Description

この発明は手用温熱具に関し、より特定的には、乾燥した手のケアに用いられる手用温熱具に関する。   The present invention relates to a hand warmer, and more particularly to a hand warmer used for dry hand care.

この種の従来技術の一例として、非特許文献1,2においてヒートミトンという手用温熱具が開示されている。ヒートミトンは、セパレートタイプのミトン型温熱具であり、左右両手に対応する一対のミトン本体と、各ミトン本体内に設けられかつ内部を温めるための電熱線と、電熱線に接続される電気コードと、電気コードに設けられかつヒートミトンを起動/停止するためのスイッチとを含む。   As an example of this type of prior art, Non-Patent Documents 1 and 2 disclose a hand warmer called a heat mittens. Heat mittens are separate type mittens type heating devices, a pair of mittens main body corresponding to both left and right hands, a heating wire provided in each mittens main body for heating the inside, and an electric cord connected to the heating wire And a switch provided on the electric cord and for starting / stopping the heat mittens.

使用時には、両手にハンドクリームや美容液を塗った後、両手をラッピングしておく。そして、電気コードのプラグをコンセントに差し込み、一対のミトン本体に両手を差し込んだ後、スイッチによりヒートミトンを起動し、その状態で両手をたとえば15分程度温める。所定時間が経過すると、一対のミトン本体から両手を抜き出す。   When using, wrap both hands after applying hand cream or serum to both hands. Then, after inserting the plug of the electric cord into the outlet and inserting both hands into the pair of mittens main bodies, the heat mittens are activated by the switch, and both hands are warmed for about 15 minutes, for example. When a predetermined time has elapsed, both hands are extracted from the pair of mittens main bodies.

セレクション ヒートミトン(1双)、[online]、[平成27年6月29日検索]、インターネット<URL:http://www.lifebeauty.jp/products/detail.php?product_id=17169>Selection Heat Mittens (1 pair), [online], [Search June 29, 2015], Internet <URL: http://www.lifebeauty.jp/products/detail.php?product_id=17169> エレクトリック ヒートミトン、[online]、[平成27年6月29日検索]、インターネット<URL: http://fontanamoco.jp/products/detail/1611>Electric Heat Mittens, [online], [Search June 29, 2015], Internet <URL: http://fontanamoco.jp/products/detail/1611>

しかしながら、ヒートミトンを使用するためには電源が必要であり、使用できる場所が制限される。また、ヒートミトンは一対のミトン本体を有するセパレートタイプであるため、一方の手に一方のミトン本体を装着した状態で他方の手に他方のミトン本体を装着する際には、未装着のミトン本体をミトン本体装着済の手で保持しなければならず、ミトン本体を円滑に装着できない場合がある。また、両手にミトン本体を装着した状態で一方のミトン本体を取り外す際にも、ミトン本体装着済の手で他方の取り外すべきミトン本体を保持しなければならず、ミトン本体を円滑に取り外すことができない場合がある。さらに、ヒートミトンは電熱線および電気コード等の電気部品を含むので電気部品の劣化や感電を防ぐために、非特許文献2に記載されているように、折りたたんだ状態での使用や洗濯機での洗濯が禁止されている。このようにヒートミトンは取扱いが容易ではない。   However, in order to use heat mitten, a power source is required, and the place where it can be used is limited. In addition, since the heat mittens are a separate type having a pair of mittens main bodies, when one mittens main body is attached to one hand and the other mittens main body is attached to the other hand, the unattached mittens main body Must be held by the hand with the mittens body already mounted, and the mittens body may not be mounted smoothly. Also, when removing one of the mittens bodies with both hands attached, the other mittens body to be removed must be held with the mittens body attached hand so that the mittens body can be removed smoothly. There are cases where it is not possible. Furthermore, since heat mittens include electric parts such as heating wires and electric cords, as described in Non-Patent Document 2, in order to prevent deterioration of electric parts and electric shock, it is used in a folded state or in a washing machine. Washing is prohibited. Thus, heat mittens are not easy to handle.

それゆえにこの発明の主たる目的は、使用場所が制限されず取扱いが容易である、手用温熱具を提供することである。   Therefore, a main object of the present invention is to provide a hand warmer that is easy to handle without being restricted in place of use.

この発明の或る見地によれば、少なくとも使用時において筒状に形成される温熱具本体と、温熱具本体に収容される断熱部材とを備える、手用温熱具が提供される。   According to a certain aspect of the present invention, there is provided a hand warming tool including at least a heating tool main body formed in a cylindrical shape during use and a heat insulating member accommodated in the heating tool main body.

この発明では、筒状に形成された温熱具本体の両側開口部から両手を挿入しその状態を維持することで断熱部材が体温を逃がさず、手を温めることができる。これによって血行を促進し、手に潤いを与えることができる。このように体温を利用するので、高温にならず、電源は不要であり、使用場所が制限されることなく任意の場所で使用できる。また、温熱具本体が両手一体型であるため、片手を挿入するだけで温熱具本体は保持され、他方の手への温熱具本体の着脱が容易になる。さらに、電熱線および電気コード等の電気部品も不要であるので、折りたたんだ状態での使用や洗濯機での洗濯が禁止されることもない。したがって、取り扱いも容易である。   In this invention, a heat insulating member does not escape body temperature and can warm a hand by inserting both hands from the both-sides opening part of the heating tool main body formed in the cylinder shape, and maintaining the state. This can promote blood circulation and moisturize the hands. Since the body temperature is used in this way, the temperature does not become high, a power source is unnecessary, and the device can be used in any place without being restricted in use place. Moreover, since the heating tool main body is a two-hand integrated type, the heating tool main body is held only by inserting one hand, and the heating tool main body can be easily attached to and detached from the other hand. Furthermore, since electric parts such as a heating wire and an electric cord are not necessary, use in a folded state or washing in a washing machine is not prohibited. Therefore, handling is also easy.

好ましくは、温熱具本体を筒状に形成した状態において少なくとも温熱具本体の軸方向に延びるように温熱具本体に形成される第1ステッチと、第1ステッチと交差する方向に延びるように温熱具本体に形成される複数の第2ステッチとをさらに含む。この場合、第1ステッチと第2ステッチとによって温熱具本体内での断熱部材の移動範囲を制限できる。すなわち、第1ステッチおよび第2ステッチによって、温熱具本体における断熱部材の収容バランスを調整でき、第1ステッチおよび第2ステッチが形成されない場合よりも高い保温効果を得ることができる。   Preferably, in a state where the main body of the heating tool is formed in a cylindrical shape, the first stitch formed in the main body of the heating tool so as to extend at least in the axial direction of the main body of the heating tool, and the heating tool so as to extend in a direction intersecting the first stitch And a plurality of second stitches formed on the main body. In this case, the movement range of the heat insulating member in the heating tool body can be limited by the first stitch and the second stitch. That is, the accommodation balance of the heat insulating member in the heating tool body can be adjusted by the first stitch and the second stitch, and a higher heat retention effect can be obtained than when the first stitch and the second stitch are not formed.

また好ましくは、温熱具本体を展開した状態において、第1ステッチの少なくとも一端は温熱具本体の縁部に至らず、各第2ステッチの両端は温熱具本体の縁部に至らない。この場合、第2ステッチの延長線上にある温熱具本体の縁部は、第2ステッチによって区切られないので、温熱具本体を展開した状態において、温熱具本体の中央寄りよりも温熱具本体の当該縁部寄りの方が、温熱具本体の厚み方向に膨らむことができる。よって、温熱具本体の当該縁部寄りには多くの断熱部材が収容され、温熱具本体の厚みは、温熱具本体の中央寄りよりも温熱具本体の当該縁部寄りの方が大きくなる。したがって、たとえば温熱具本体の中央部で温熱具本体を折り返し、温熱具本体の当該縁部を重ね合わせて温熱具本体を筒状にした場合の厚みは、温熱具本体の当該縁部を重ね合わせた側の方が、他方(折り返された側)より大きくなる。温熱具本体の厚みが大きい方を身体に対して外側(奥側)に位置するように温熱具本体を配置すれば、温熱具本体の高さは手前側が低くなり奥側が高くなる。よって、本等を温熱具本体の外表面にもたれかけさせると紙面が身体側に向くように本等が傾き鑑賞しやすくなる。また、筒状にした温熱具本体内部に手を挿入したとき、温熱具本体の内面においても手前側が低くなり奥側が高くなるので、温熱具本体に挿入された手の位置を安定させることができる。さらに、断熱部材は温熱具本体の縁部を通って温熱具本体内の全域に移動可能であるので、たとえば、一箇所の断熱部材収容口から温熱具本体内の全域に断熱部材を供給できる。   Preferably, in a state where the heating tool body is deployed, at least one end of the first stitch does not reach the edge of the heating tool body, and both ends of each second stitch do not reach the edge of the heating tool body. In this case, since the edge of the main body of the heating tool on the extension line of the second stitch is not delimited by the second stitch, in the state where the main body of the heating tool is expanded, the edge of the heating tool body is closer to the center of the heating tool body. The side closer to the edge can swell in the thickness direction of the heating tool body. Therefore, many heat insulating members are accommodated near the edge of the heating tool body, and the thickness of the heating tool body is larger at the edge of the heating tool body than at the center of the heating tool body. Therefore, for example, when the heating tool body is folded at the center of the heating tool body, and the edge of the heating tool body is overlapped to make the heating tool body cylindrical, the thickness of the heating tool body is overlapped. One side is larger than the other (folded side). If the heating tool body is arranged so that the thicker one of the heating tool body is positioned outside (back side) with respect to the body, the height of the heating tool body becomes lower on the near side and higher on the back side. Therefore, when the book or the like is leaned against the outer surface of the main body of the heating tool, the book or the like can be easily tilted so that the paper surface faces the body side. Moreover, when the hand is inserted into the cylindrical heating device main body, the front side is lowered and the back side is also increased on the inner surface of the heating device main body, so that the position of the hand inserted into the heating device main body can be stabilized. . Furthermore, since the heat insulating member can move through the edge of the main body of the heating tool to the entire area within the main body of the heating apparatus, for example, the heat insulating member can be supplied from one heat insulating member housing port to the entire area of the main body of the heating apparatus.

さらに好ましくは、各第2ステッチは第1ステッチに略直交する。このように第1ステッチと第2ステッチとの交差角を略直角にすることで、第1ステッチと第2ステッチとの交差箇所付近にも断熱部材を供給しやすくなり、さらに安定した保温効果を得ることができる。   More preferably, each second stitch is substantially orthogonal to the first stitch. Thus, by making the crossing angle between the first stitch and the second stitch substantially perpendicular, it becomes easier to supply the heat insulating member near the crossing point between the first stitch and the second stitch, and a more stable heat retaining effect is achieved. Can be obtained.

好ましくは、温熱具本体の中央部を跨いで位置する一対の隣り合う第2ステッチ同士の温熱具本体の軸方向の間隔が、他の隣り合う第2ステッチ同士の温熱具本体の軸方向の間隔よりも大きい。この場合、温熱具本体の中央付近の厚みは温熱具本体の軸方向両端側の厚みよりも大きく、筒状に形成された温熱具本体の内部空間は、温熱具本体の軸方向両端側では広くなり、温熱具本体の中央付近では狭くなる。したがって、使用時において、筒状に形成された温熱具本体の軸方向両端から手を挿入しやすく、手を温熱具本体の中央付近まで挿入すると、手が温熱具本体と密着し、高い保温効果が得られる。また、手を温熱具本体の中央付近まで挿入するだけで温熱具本体と手とが密着することから、温熱具本体を保持することが容易になる。   Preferably, the distance between the pair of adjacent second stitches located across the central portion of the heating tool body in the axial direction of the heating tool body is the distance between the other adjacent second stitches in the axial direction of the heating tool body. Bigger than. In this case, the thickness near the center of the heating tool body is larger than the thickness at both axial ends of the heating tool body, and the inner space of the heating tool body formed in a cylindrical shape is wide at both axial ends of the heating tool body. It becomes narrow near the center of the heating tool body. Therefore, in use, it is easy to insert a hand from both ends in the axial direction of the heating device body formed in a cylindrical shape, and when the hand is inserted to the vicinity of the center of the heating device body, the hand is in close contact with the heating device body, and a high heat retention effect Is obtained. In addition, since the heating tool body and the hand are in close contact with each other just by inserting the hand to the vicinity of the center of the heating tool body, the heating tool body can be easily held.

また好ましくは、温熱具本体を筒状に保持するための保持部材をさらに含む。この場合、保持部材によって温熱具本体を筒状に保持でき、手用温熱具を手のケアのために使用できる。また、温熱具本体を展開した状態では、手用温熱具を膝掛けや座布団等としても使用することが可能である。このように、手用温熱具は、手をケアするだけではなく様々な用途を有する。   Preferably, it further includes a holding member for holding the heating tool main body in a cylindrical shape. In this case, the heating tool main body can be held in a cylindrical shape by the holding member, and the hand heating tool can be used for hand care. In the state where the main body of the heating device is deployed, the hand heating device can be used as a lap or a cushion. Thus, the hand warmer has various uses as well as hand care.

さらに好ましくは、保持部材は、温熱具本体に設けられるファスナを含む。この場合、ファスナの取扱いは簡単であるため、使用時に温熱具本体を筒状に保持することが容易である。   More preferably, a holding member contains the fastener provided in a heating tool main body. In this case, since the handling of the fastener is simple, it is easy to hold the heating tool body in a cylindrical shape during use.

好ましくは、温熱具本体はポリエステルからなる。この場合、ポリエステルは弾力性が高くかつ吸水性が低いという特徴を有するので、温熱具本体を誤って落下させてしまっても破損する可能性は低く、また、濡れても乾きやすく、取扱いが容易である。   Preferably, the heating tool body is made of polyester. In this case, polyester has the characteristics of high elasticity and low water absorption, so it is unlikely to be damaged even if the heating tool body is accidentally dropped, and it is easy to dry even when wet and easy to handle. It is.

また好ましくは、断熱部材は発泡部材からなる。この場合、発泡部材は断熱効果が高くかつ吸水性が低いという特徴を有するので、体温を逃がさず高い保温効果を得ることができ、また、吸水による劣化はし難く長期間にわたり断熱効果を保つことができる。   Preferably, the heat insulating member is made of a foam member. In this case, since the foamed member has the characteristics that the heat insulating effect is high and the water absorption is low, a high heat retaining effect can be obtained without escaping the body temperature, and it is difficult to deteriorate due to water absorption, and the heat insulating effect is maintained over a long period of time. Can do.

この発明によれば、使用場所が制限されず取扱いが容易である手用温熱具が得られる。   According to the present invention, a hand warmer that is easy to handle without being restricted in place of use can be obtained.

以下、図面を参照してこの発明の実施形態について説明する。なお、この発明の実施形態において、長手方向とは図1において矢印Lで示す方向、短手方向とは図1において矢印Sで示す方向、厚み方向とは図2において矢印Tで示す方向、軸方向とは図6において矢印Pで示す方向である。   Embodiments of the present invention will be described below with reference to the drawings. In the embodiment of the present invention, the longitudinal direction is the direction indicated by the arrow L in FIG. 1, the short direction is the direction indicated by the arrow S in FIG. 1, and the thickness direction is the direction indicated by the arrow T in FIG. The direction is a direction indicated by an arrow P in FIG.

図1〜図3を参照して、この発明の一実施形態の手用温熱具10は、温熱具本体12と断熱部材14とを含む。この実施形態では、温熱具本体12は、変形可能なポリエステルからなる生地を縫い合わせることによって袋状に形成される。温熱具本体12の伸縮率は、矢印Lで示す長手方向より矢印Sで示す短手方向の方が大きく、好ましくは、温熱具本体12はワンウェイ生地からなる。断熱部材14は発泡部材、より具体的には発泡ビーズからなり、温熱具本体12内に収容される。   1 to 3, a hand warming tool 10 according to an embodiment of the present invention includes a heating tool body 12 and a heat insulating member 14. In this embodiment, the heating tool body 12 is formed into a bag shape by sewing together fabrics made of deformable polyester. The expansion / contraction rate of the heating tool body 12 is greater in the short direction indicated by the arrow S than in the longitudinal direction indicated by the arrow L, and preferably, the heating tool body 12 is made of a one-way fabric. The heat insulating member 14 is made of a foam member, more specifically, a foam bead, and is accommodated in the heating tool main body 12.

温熱具本体12には、第1ステッチ16と複数(この実施形態では、8本)の第2ステッチ18a〜18hとが形成され、ファスナ20および断熱部材収容口22が設けられている。   The heating tool body 12 is formed with a first stitch 16 and a plurality (eight in this embodiment) of second stitches 18a to 18h, and a fastener 20 and a heat insulating member accommodation port 22 are provided.

第1ステッチ16および第2ステッチ18a〜18hは、温熱具本体12を構成するために対向する生地(図1でいえば、上側の生地と下側の生地)を縫い合わせることによって形成される。これによって、温熱具本体12内における断熱部材14の移動範囲が制限される。   The first stitch 16 and the second stitches 18a to 18h are formed by stitching together facing fabrics (upper fabric and lower fabric in FIG. 1) to constitute the heating tool body 12. Thereby, the movement range of the heat insulating member 14 in the heating tool main body 12 is limited.

温熱具本体12を展開した状態において、第1ステッチ16は、温熱具本体12の短手方向中央部において温熱具本体12の長手方向に延びるように形成されている。したがって、第1ステッチ16は、温熱具本体12を筒状に形成した状態において少なくとも温熱具本体12の軸方向に延びるように温熱具本体12に形成される。温熱具本体12を展開した状態において、第1ステッチ16の少なくとも一端は温熱具本体12の縁部13に至らない。この実施形態では、第1ステッチ16の一方端は温熱具本体12の長手方向端部12aに位置し、第1ステッチ16の他方端は温熱具本体12の長手方向端部12bに至らない。ここで、温熱具本体12の縁部13は、温熱具本体12の長手方向両端部12a,12bおよび短手方向両端部12c,12dを含む。   The first stitch 16 is formed so as to extend in the longitudinal direction of the heating tool body 12 at the center in the short direction of the heating tool body 12 in a state where the heating tool body 12 is expanded. Accordingly, the first stitch 16 is formed in the heating tool body 12 so as to extend at least in the axial direction of the heating tool body 12 in a state where the heating tool body 12 is formed in a cylindrical shape. In a state where the heating tool body 12 is deployed, at least one end of the first stitch 16 does not reach the edge 13 of the heating tool body 12. In this embodiment, one end of the first stitch 16 is located at the longitudinal end 12 a of the heating tool body 12, and the other end of the first stitch 16 does not reach the longitudinal end 12 b of the heating tool body 12. Here, the edge 13 of the heating tool body 12 includes both longitudinal ends 12a, 12b and both lateral ends 12c, 12d of the heating tool body 12.

第2ステッチ18a〜18hは、第1ステッチ16と交差する方向に延びるように、好ましくは、第1ステッチ16に直交または略直交する(温熱具本体12の短手方向に延びる)ように、温熱具本体12に形成されている。温熱具本体12を展開した状態において、第2ステッチ18a〜18hのそれぞれの両端は温熱具本体12の縁部13に至らない。この実施形態では、第2ステッチ18a〜18hのそれぞれの両端は温熱具本体12の短手方向両端部12c,12dに至らない。各第2ステッチ18a〜18hの長さは略等しい。また、隣り合う第2ステッチ18dと18eとの間隔は、他の隣り合う第2ステッチ同士18aと18b,18bと18c,18cと18d,18eと18f,18fと18g,18gと18hのそれぞれの間隔よりも大きい。以下、隣り合う第2ステッチ18dと18eとの間を幅広部24といい、隣り合う第2ステッチ同士18aと18b,18bと18c,18cと18d,18eと18f,18fと18g,18gと18hのそれぞれの間を幅狭部26という。幅広部24は温熱具本体12の長手方向中央部を跨いでいる。各幅狭部26の間隔は、概ね等しい。   The second stitches 18a to 18h extend in a direction intersecting the first stitch 16, preferably in a direction orthogonal to or substantially orthogonal to the first stitch 16 (extends in the short direction of the heating tool body 12). The tool body 12 is formed. In the state where the heating tool main body 12 is deployed, both ends of the second stitches 18 a to 18 h do not reach the edge 13 of the heating tool main body 12. In this embodiment, both ends of each of the second stitches 18 a to 18 h do not reach the short-side ends 12 c and 12 d of the heating tool body 12. The lengths of the second stitches 18a to 18h are substantially equal. The intervals between the adjacent second stitches 18d and 18e are the intervals between the other adjacent second stitches 18a and 18b, 18b and 18c, 18c and 18d, 18e and 18f, 18f and 18g, and 18g and 18h. Bigger than. Hereinafter, the space between the adjacent second stitches 18d and 18e is referred to as the wide portion 24, and the adjacent second stitches 18a and 18b, 18b and 18c, 18c and 18d, 18e and 18f, 18f and 18g, 18g and 18h The space between each is referred to as a narrow portion 26. The wide portion 24 straddles the central portion in the longitudinal direction of the heating tool body 12. The intervals between the narrow portions 26 are substantially equal.

第1ステッチ16および第2ステッチ18a〜18hの長さや間隔を変えることによって、温熱具本体12に断熱部材14を収容したときの温熱具本体12の厚み方向の膨らみを調整できる。   By changing the lengths and intervals of the first stitch 16 and the second stitches 18a to 18h, the bulge in the thickness direction of the heating tool body 12 when the heat insulation member 14 is accommodated in the heating tool body 12 can be adjusted.

保持部材としてのファスナ20は、温熱具本体12の短手方向両端部12c,12dにそれぞれ設けられる一対のテープ20a,20bと、一対のテープ20a,20bにそれぞれ設けられる一対の務歯20c,20dと、テープ20aにおける温熱具本体12の長手方向の両端部に設けられるストッパー20e,20fと、テープ20bにおける温熱具本体12の長手方向の一端に設けられるストッパー20gおよび他端に設けられるピン20hと、務歯20cに摺動可能に取りつけられる第1スライダ20iおよび第2スライダ20jとを含む。ストッパー20eおよび20gは、第1スライダ20iの摺動範囲を規制し、ストッパー20fは、第2スライダ20jの摺動範囲を規制する。ピン20hは、一対の務歯20c,20d同士を結合する際に、第1スライダ20iと第2スライダ20jとに差し込まれ、一対の務歯20c,20d同士の位置関係を定めるためのものである。ストッパー20fおよびピン20hはファスナ開始点に相当し、ストッパー20eおよび20gはファスナ終点に相当する。   The fastener 20 as a holding member includes a pair of tapes 20a and 20b provided at both ends 12c and 12d in the short direction of the heating tool body 12, and a pair of service teeth 20c and 20d provided at the pair of tapes 20a and 20b, respectively. And stoppers 20e and 20f provided at both ends in the longitudinal direction of the heating tool body 12 in the tape 20a, a stopper 20g provided at one end in the longitudinal direction of the heating tool body 12 in the tape 20b, and a pin 20h provided at the other end. The first slider 20i and the second slider 20j are slidably attached to the engagement teeth 20c. The stoppers 20e and 20g regulate the sliding range of the first slider 20i, and the stopper 20f regulates the sliding range of the second slider 20j. The pin 20h is inserted into the first slider 20i and the second slider 20j when the pair of service teeth 20c and 20d are coupled to each other, and determines the positional relationship between the pair of service teeth 20c and 20d. . The stopper 20f and the pin 20h correspond to the fastener start point, and the stoppers 20e and 20g correspond to the fastener end point.

断熱部材収容口22は、温熱具本体12の長手方向端部12bの略中央部において、温熱具本体12の外側へ突出するように設けられている。図1において一点鎖線の矢印Xで示すように、断熱部材14は、断熱部材収容口22から温熱具本体12の内部へ供給され、その後、断熱部材収容口22は閉じられる。断熱部材収容口22は、図1において二点鎖線で示すように温熱具本体12の内部に収納できる。   The heat insulating member accommodation port 22 is provided so as to protrude to the outside of the heating tool body 12 at a substantially central portion of the longitudinal end portion 12 b of the heating tool body 12. As shown by the one-dot chain line arrow X in FIG. 1, the heat insulating member 14 is supplied from the heat insulating member accommodation port 22 to the inside of the heating device main body 12, and then the heat insulation member accommodation port 22 is closed. The heat insulation member accommodation port 22 can be accommodated in the heating tool main body 12 as shown by a two-dot chain line in FIG.

図1および図2を参照して、各第2ステッチ間における温熱具本体12の厚み方向の膨らみを比較すると、幅広部24の膨らみは、各幅狭部26の膨らみよりも大きい。これは、幅広部24の方が各幅狭部26よりも断熱部材14を収容できる容積が大きく厚み方向に膨らむことができ、幅広部24の方が各幅狭部26よりも多くの断熱部材14を収容しているからである。   Referring to FIG. 1 and FIG. 2, when comparing the swelling in the thickness direction of the heating tool body 12 between the second stitches, the swelling of the wide portion 24 is larger than the swelling of each narrow portion 26. This is because the wide portion 24 has a larger volume capable of accommodating the heat insulating member 14 than each narrow portion 26 and can expand in the thickness direction, and the wide portion 24 has more heat insulating members than each narrow portion 26. It is because 14 is accommodated.

図1および図3を参照して、幅狭部26を通る温熱具本体12の短手方向において、温熱具本体12の厚み方向の膨らみを比較すると、温熱具本体12の中央寄り(第1ステッチ16側)の膨らみよりも温熱具本体12の両端部12c,12d寄りの膨らみの方が大きい。これは、温熱具本体12において、第1ステッチ16と第2ステッチ18a〜18hとで区分けされた温熱具本体12の中央寄りよりも、ステッチ等によって区分けされていない温熱具本体12の両端部12c,12d寄りの方が、厚み方向に膨らむことができ、温熱具本体12の両端部12c,12d寄りには多くの断熱部材14が収容されているからである。   Referring to FIG. 1 and FIG. 3, when the swelling in the thickness direction of the heating tool main body 12 is compared in the short direction of the heating tool main body 12 passing through the narrow portion 26, the center of the heating tool main body 12 (first stitch) is compared. The bulges near the both end portions 12c and 12d of the heating tool body 12 are larger than the bulges on the 16 side). This is because both ends 12c of the heating tool main body 12 that are not divided by stitches or the like are located closer to the center of the heating tool main body 12 divided by the first stitch 16 and the second stitches 18a to 18h. , 12d side can swell in the thickness direction, and many heat insulating members 14 are accommodated near both end portions 12c, 12d of the heating tool body 12.

したがって、温熱具本体12を展開した状態では、幅広部24を含む温熱具本体12の中央部の厚み、および温熱具本体12の短手方向両端部12c,12dにおいて温熱具本体12の長手方向に延びる部分の厚みは、幅狭部26の厚みより大きい。   Therefore, in the state where the heating tool main body 12 is deployed, the thickness of the central portion of the heating tool main body 12 including the wide portion 24 and the longitudinal direction both ends 12c and 12d of the heating tool main body 12 are arranged in the longitudinal direction of the heating tool main body 12. The extending portion is thicker than the narrow portion 26.

図4を参照して、温熱具本体12の形状(平面視輪郭)を断熱部材14の収容前後で比較すると、温熱具本体12の長手方向全長および短手方向全長ともに、断熱部材14の収容前よりも断熱部材14の収容後の方が短い。これは、温熱具本体12の内部に断熱部材14を収容することで、温熱具本体12が温熱具本体12の厚み方向に膨らみ、それに伴って、温熱具本体12の長手方向の長さおよび短手方向の長さが短くなるからである。また、温熱具本体12の長手方向全長の減少量については、温熱具本体12の短手方向中央における減少量L1が、温熱具本体12の短手方向両端部12c,12d付近における減少量L2よりも大きい。これは、第2ステッチ18a〜18hで区分けされた温熱具本体12の短手方向中央寄りでは、温熱具本体12は隣り合う第2ステッチ間ごとに温熱具本体12の厚み方向に膨らみ、隣り合う第2ステッチ間ごとに温熱具本体12の長手方向の長さが短くなる(隣り合う第2ステッチの間隔が短くなる)からである。温熱具本体12の長手方向全長の減少率についても、第2ステッチ18a〜18hに区分けされている温熱具本体12の短手方向中央付近の減少率の方が、第2ステッチ18a〜18hに区分けされていない温熱具本体12の短手方向両端部12c,12d付近の減少率よりも大きい。   Referring to FIG. 4, when comparing the shape (planar outline in plan view) of the heating tool body 12 before and after housing the heat insulating member 14, both the length in the longitudinal direction and the length in the short direction of the heating tool body 12 are both before housing the heat insulating member 14. It is shorter after the insulation member 14 is accommodated. This is because the heat insulating member 14 is accommodated in the heating tool main body 12 so that the heating tool main body 12 swells in the thickness direction of the heating tool main body 12, and accordingly, the length and short length of the heating tool main body 12 in the longitudinal direction. This is because the length in the hand direction is shortened. In addition, regarding the amount of decrease in the overall length in the longitudinal direction of the heater main body 12, the amount of decrease L1 at the center in the short direction of the heater main body 12 is less than the amount of decrease L2 in the vicinity of both ends 12c and 12d in the short direction of the heater main body 12. Is also big. This is because the heating tool body 12 swells in the thickness direction of the heating tool body 12 between adjacent second stitches and is adjacent to the center of the heating tool body 12 divided by the second stitches 18a to 18h. This is because the length of the heating tool body 12 in the longitudinal direction is shortened between the second stitches (the interval between adjacent second stitches is shortened). Regarding the rate of reduction of the overall length in the longitudinal direction of the heating device body 12, the rate of reduction near the center in the short direction of the heating device body 12 divided into the second stitches 18a to 18h is divided into the second stitches 18a to 18h. It is larger than the decrease rate in the vicinity of both ends 12c and 12d in the short direction of the heating tool body 12 that is not provided.

温熱具本体12(手用温熱具10)はファスナ20によって筒状に保持される。   The heating tool body 12 (hand heating tool 10) is held in a cylindrical shape by a fastener 20.

展開された状態の温熱具本体12を筒状に形成する際には、まず、温熱具本体12を温熱具本体12の短手方向中央(第1ステッチ16)で折り返し、一対の務歯20cと20dとを向い合せる。次に、第2スライダ20jをストッパー20fの方向へ、ストッパー20fによって動きが規制されるまで摺動させ、第1スライダ20iを第2スライダ20jの方向へ、第2スライダ20jによって動きが規制されるまで摺動させる。そして、ピン20hを、第1スライダ20i,第2スライダ20jの順に、ストッパー20fに対応する位置まで差し込む。その後、第2スライダ20jを摺動させず、第1スライダ20iをストッパー20e,20gの方向に、ストッパー20e,20gによって動きが規制されるまで摺動させる。すると、一対の務歯20cと20dとが結合し、温熱具本体12を筒状に保持することができる。   When the heating tool main body 12 in the unfolded state is formed into a cylindrical shape, first, the heating tool main body 12 is folded back at the center of the heating tool main body 12 in the short direction (first stitch 16), and a pair of service teeth 20c and Face 20d. Next, the second slider 20j is slid in the direction of the stopper 20f until the movement is restricted by the stopper 20f, and the movement of the first slider 20i is restricted in the direction of the second slider 20j by the second slider 20j. Slide until. Then, the pin 20h is inserted in the order of the first slider 20i and the second slider 20j to a position corresponding to the stopper 20f. Thereafter, without sliding the second slider 20j, the first slider 20i is slid in the direction of the stoppers 20e and 20g until the movement is restricted by the stoppers 20e and 20g. Then, the pair of service teeth 20c and 20d are combined, and the heating tool main body 12 can be held in a cylindrical shape.

務歯20cと20dとを結合できる範囲は、第1スライダ20iと第2スライダ20jとの間である。したがって、第1スライダ20iおよび/または第2スライダ20jを摺動させ、第1スライダ20iおよび第2スライダ20jの停止位置を調整することで、筒状の手用温熱具10の軸方向両端から両手を挿入し易いように、温熱具本体12の結合範囲を変更することができる。   The range in which the engagement teeth 20c and 20d can be coupled is between the first slider 20i and the second slider 20j. Therefore, by sliding the first slider 20i and / or the second slider 20j and adjusting the stop positions of the first slider 20i and the second slider 20j, both hands from both ends in the axial direction of the tubular hand-heated heater 10 can be obtained. It is possible to change the coupling range of the heating tool body 12 so that it can be easily inserted.

図5および図6を参照して、温熱具本体12を筒状に保持した状態では、温熱具本体12は、第1ステッチ16側が収縮し略円弧状を呈する。これは、上述したように、温熱具本体12の展開時において、温熱具本体12の長手方向全長の減少率(減少量)については、第2ステッチ18a〜18hによって区分けされた温熱具本体12の短手方向中央付近の減少率(減少量)の方が、第2ステッチ18a〜18hによって区分けされていない温熱具本体12の短手方向両端部12c,12d付近の減少率(減少量)よりも大きいためである。すなわち、温熱具本体12を筒状に保持した状態において、温熱具本体12の展開時に温熱具本体12の短手方向中央に位置していた第1ステッチ16側が、温熱具本体12のファスナ20側よりも、温熱具本体12の軸方向全長の減少率が大きくなるため、温熱具本体12は自然と略円弧状を呈する。   With reference to FIG. 5 and FIG. 6, in a state where the heating tool body 12 is held in a cylindrical shape, the heating tool body 12 contracts on the first stitch 16 side and has a substantially arc shape. As described above, when the heating tool main body 12 is deployed, the reduction rate (decrease amount) of the overall length in the longitudinal direction of the heating tool main body 12 is that of the heating tool main body 12 divided by the second stitches 18a to 18h. The reduction rate (decrease amount) near the center in the short direction is less than the reduction rate (decrease amount) in the vicinity of both ends 12c and 12d in the short direction of the heating device body 12 that is not divided by the second stitches 18a to 18h. Because it is big. That is, in a state where the heating tool body 12 is held in a cylindrical shape, the first stitch 16 side that is located at the center of the heating tool body 12 in the short direction when the heating tool body 12 is deployed is the fastener 20 side of the heating tool body 12. Since the decreasing rate of the axial direction full length of the heating tool main body 12 becomes larger than that, the heating tool main body 12 naturally exhibits a substantially circular arc shape.

また、図7および図8を参照して、筒状にしたときの温熱具本体12の軸方向端部付近および図6に示すD−D断面における厚みは、第1ステッチ16側よりもファスナ20側の方が大きくなる。これは、上述したように、展開時の温熱具本体12において、第1ステッチ16および第2ステッチ18a〜18hによって区分けされた温熱具本体12の中央寄りよりも、第1ステッチ16および第2ステッチ18a〜18hによって区分けされていない温熱具本体12の両端部12c,12d寄りの方が、厚み方向の膨らみが大きいからである。すなわち、温熱具本体12を筒状にすると、第1ステッチ16側の厚みは展開時の温熱具本体12の中央寄りの厚みを重ね合わせた厚みとなり、ファスナ20側の厚みは展開時の温熱具本体12の両端部12c,12d寄りの厚みを重ね合わせた厚みとなるため、温熱具本体12の厚みは、第1ステッチ16側よりもファスナ20側の方が大きくなる。   7 and 8, the thickness in the vicinity of the axial end portion of the heating tool body 12 and the DD cross section shown in FIG. The side becomes larger. As described above, this is because the first stitch 16 and the second stitch are located closer to the center of the heating tool body 12 divided by the first stitch 16 and the second stitches 18a to 18h in the heating tool body 12 at the time of deployment. This is because the bulge in the thickness direction is larger in the direction closer to both ends 12c and 12d of the heating tool body 12 that is not divided by 18a to 18h. That is, when the heating tool body 12 is formed in a cylindrical shape, the thickness on the first stitch 16 side is a thickness obtained by superposing the thicknesses of the heating tool body 12 near the center of the deployment, and the thickness on the fastener 20 side is the heating tool on deployment. Since the thickness of the main body 12 near the both end portions 12c and 12d is superposed, the thickness of the heating tool main body 12 is larger on the fastener 20 side than on the first stitch 16 side.

また、図9を参照して、筒状にした温熱具本体12の内側において、温熱具本体12の両端側は開口されているが、温熱具本体12の軸方向(長手方向)中央付近は温熱具本体12同士が接触し閉じられている。これは、温熱具本体12の厚み方向の膨らみを比較すると、幅広部24の膨らみが幅狭部26および幅狭部26より端の部分の膨らみよりも大きいからである。すなわち、温熱具本体12を筒状にすると、温熱具本体12の厚み方向の膨らみは、幅狭部26よりも幅広部24の方が大きく、幅広部24では温熱具本体12同士が接触するが、幅狭部26では温熱具本体12同士は接触しない。また、温熱具本体12の端部12aと第2ステッチ18aとで区分けされた範囲、および温熱具本体12の端部12bと第2ステッチ18hとで区分けされた範囲においては、幅広部24および幅狭部26よりも断熱部材14の収容量が少なく、温熱具本体12の厚み方向の膨らみは小さいので、温熱具本体12同士は接触しない。したがって、温熱具本体12の内側において、温熱具本体12の両端側は開口されているが、温熱具本体12の軸方向中央付近は温熱具本体12同士が接触し閉じられている。   Referring to FIG. 9, both ends of the heating tool body 12 are opened inside the cylindrical heating tool body 12, but the vicinity of the center in the axial direction (longitudinal direction) of the heating tool body 12 is warm. The tool bodies 12 are in contact with each other and closed. This is because the bulge of the wide portion 24 is larger than the bulge of the narrow portion 26 and the end portion of the narrow portion 26 when the bulges in the thickness direction of the heating tool body 12 are compared. That is, when the heating tool main body 12 is formed into a cylindrical shape, the swelling in the thickness direction of the heating tool main body 12 is larger in the wide portion 24 than in the narrow portion 26, and the heating tool main bodies 12 are in contact with each other in the wide portion 24. In the narrow portion 26, the heating tool bodies 12 do not contact each other. Further, in the range divided by the end portion 12a of the heating tool body 12 and the second stitch 18a, and in the range divided by the end portion 12b of the heating tool body 12 and the second stitch 18h, the wide portion 24 and the width Since the accommodation amount of the heat insulating member 14 is smaller than that of the narrow portion 26 and the bulge in the thickness direction of the heating tool body 12 is small, the heating tool bodies 12 do not contact each other. Therefore, both ends of the heating tool body 12 are opened inside the heating tool body 12, but the heating tool bodies 12 are in contact with each other and are closed near the center in the axial direction of the heating tool body 12.

手用温熱具10の実際の使用例について説明する。   An actual usage example of the hand warmer 10 will be described.

まず、手を洗って汚れを落として手を完全に拭く。次に、手に潤いを与える第1ハンドクリームまたは美容液を両手に塗布し、手袋(通気性のあるものが望ましい)を両手に装着し、筒状の温熱具本体12を、第1ステッチ16側を手前にして身体の前に配置する。そして、一方の手(たとえば左手)で温熱具本体12を保持しつつ他方の手(たとえば右手)を温熱具本体12の他端開口部28bから温熱具本体12内部の中央まで挿入し、その後、一方の手(たとえば左手)を温熱具本体12の一端開口部28aから温熱具本体12内部の中央まで挿入する(図9,図10参照)。ここで、片手を温熱具本体12内部の中央まで挿入した状態であれば、温熱具本体12と手とが密着し温熱具本体12は手によって自然と保持される。なお、片手が手首程度まで温熱具本体12内部に挿入されれば、挿入した手と温熱具本体12が置かれている台(机等)とによって温熱具本体12を挟むように保持することができる。また、温熱具本体12に挿入された手の指は温熱具本体12内部でも動かせるので、指で温熱具本体12内側を掴んで保持することもできる。なお、温熱具本体12は第1ステッチ16側が収縮して略円弧状を呈し、温熱具本体12の両端開口部28a,28bが少し手前に向くので、手の挿入が容易になる。   First, wash your hands, clean and wipe your hands thoroughly. Next, a first hand cream or cosmetic liquid that moisturizes the hands is applied to both hands, gloves (preferably breathable) are attached to both hands, and the tubular heating device body 12 is attached to the first stitch 16. Place it in front of you with the side facing you. And while holding the heating tool body 12 with one hand (for example, the left hand), the other hand (for example, the right hand) is inserted from the other end opening 28b of the heating tool body 12 to the center of the heating tool body 12, and then One hand (for example, the left hand) is inserted from one end opening 28a of the heating tool body 12 to the center of the heating tool body 12 (see FIGS. 9 and 10). Here, if one hand is inserted to the center of the heating tool body 12, the heating tool body 12 and the hand are in close contact with each other, and the heating tool body 12 is naturally held by the hand. In addition, if one hand is inserted into the heating tool main body 12 to the wrist level, the heating tool main body 12 may be held between the inserted hand and a table (desk or the like) on which the heating tool main body 12 is placed. it can. Moreover, since the finger of the hand inserted into the heating tool main body 12 can be moved also inside the heating tool main body 12, the inside of the heating tool main body 12 can be grasped and held by the finger. The heating tool body 12 is contracted on the first stitch 16 side so as to have a substantially arc shape, and both end openings 28a and 28b of the heating tool body 12 face slightly forward.

図10に示すように、両手を温熱具本体12内部の中央まで挿入しその状態を維持し続けると、断熱部材14が体温を逃がさず手に暖かさを感じるようになり、手を温めることができる。   As shown in FIG. 10, if both hands are inserted to the center of the heating tool main body 12 and the state is continuously maintained, the heat insulating member 14 feels warmth in the hand without releasing the body temperature. it can.

手用温熱具10によって両手を温めることができれば、両手を温熱具本体12内部に挿入した状態から、一方の手(たとえば左手)で温熱具本体12を保持しつつ他方の手(たとえば右手)を温熱具本体12から引き抜き、その後、引き抜いた手(たとえば右手)で温熱具本体12を保持しつつ一方の手(たとえば左手)を引き抜く。   If both hands can be warmed by the hand warming tool 10, the other hand (for example, the right hand) is held while holding the heating tool body 12 with one hand (for example, the left hand) from the state in which both hands are inserted into the heating tool body 12. Pull out from the heating tool body 12, and then pull out one hand (for example, the left hand) while holding the heating tool body 12 with the pulled hand (for example, the right hand).

温熱具本体12から両手を引き抜いた後、両手に装着されている手袋をはずす。ここで、手用温熱具10による手のケアを終了してもよい。しかし、保温することによって両手に馴染んだ第1ハンドクリームまたは美容液の効果をより長く持続させるために、手をコーティングする第2ハンドクリームを両手に塗布して、先に第1ハンドクリームまたは美容液を塗布した後に施したのと同様の工程を施してもよい。この場合、第2ハンドクリームを塗布しない場合よりも保温・保湿効果を長く得ることができる。   After pulling out both hands from the main body 12 of the heating tool, remove the gloves attached to both hands. Here, hand care by the hand warming tool 10 may be terminated. However, in order to maintain the effect of the first hand cream or cosmetic liquid familiar to both hands by keeping warm, the second hand cream for coating the hands is applied to both hands, and the first hand cream or beauty is first applied. You may perform the process similar to having performed after apply | coating a liquid. In this case, the heat retaining / moisturizing effect can be obtained longer than when the second hand cream is not applied.

このような手用温熱具10によれば、筒状に形成された温熱具本体12の両側開口部28a,28bから両手を挿入しその状態を維持することで断熱部材14が体温を逃がさず、手を温めることができる。これによって血行を促進し、手に潤いを与えることができる。このように体温を利用するので、高温にならず、電源は不要であり、使用場所が制限されることなく任意の場所で使用できる。また、温熱具本体12が両手一体型であるため、片手を挿入するだけで温熱具本体12は保持され、他方の手への温熱具本体12の着脱が容易になる。さらに、電熱線および電気コード等の電気部品も不要であるので、折りたたんだ状態での使用や洗濯機での洗濯が禁止されることもない。したがって、取り扱いも容易である。   According to such a hand warming tool 10, the heat insulating member 14 does not let the body temperature escape by inserting both hands from both side openings 28 a and 28 b of the heating tool body 12 formed in a cylindrical shape and maintaining the state. Can warm hands. This can promote blood circulation and moisturize the hands. Since the body temperature is used in this way, the temperature does not become high, a power source is unnecessary, and the device can be used in any place without being restricted in use place. Moreover, since the heating tool main body 12 is a two-hand integrated type, the heating tool main body 12 is held only by inserting one hand, and the heating tool main body 12 can be easily attached to and detached from the other hand. Furthermore, since electric parts such as a heating wire and an electric cord are not necessary, use in a folded state or washing in a washing machine is not prohibited. Therefore, handling is also easy.

第1ステッチ16と第2ステッチ18a〜18hとによって温熱具本体12内での断熱部材14の移動範囲を制限できる。すなわち、第1ステッチ16および第2ステッチ18a〜18hによって、温熱具本体12における断熱部材14の収容バランスを調整でき、第1ステッチ16および第2ステッチ18a〜18hが形成されない場合よりも高い保温効果を得ることができる。   The movement range of the heat insulating member 14 in the heating tool body 12 can be limited by the first stitch 16 and the second stitches 18a to 18h. That is, the accommodation balance of the heat insulating member 14 in the heating tool body 12 can be adjusted by the first stitch 16 and the second stitches 18a to 18h, and the heat retention effect is higher than when the first stitch 16 and the second stitches 18a to 18h are not formed. Can be obtained.

第2ステッチ18a〜18hの延長線上にある温熱具本体12の縁部13(短手方向両端部12c,12d)は、第2ステッチ18a〜18hによって区切られてないので、温熱具本体12を展開した状態において、温熱具本体12の中央寄りよりも温熱具本体12の両端部12c,12d寄りの方が、温熱具本体12の厚み方向に膨らむことができる。よって、温熱具本体12の両端部12c,12d寄りには多くの断熱部材14が収容され、温熱具本体12の厚みは、温熱具本体12の中央寄りよりも温熱具本体12の両端部12c,12d寄りの方が大きくなる。したがって、使用時に温熱具本体12の中央部で温熱具本体12を折り返し、温熱具本体12の両端部12c,12dを重ね合わせて温熱具本体12を筒状にした場合の厚みは、温熱具本体12の両端部12c,12dを重ね合わせた側の方が、他方(折り返された側)より大きくなる。温熱具本体12の厚みが大きい方を身体に対して外側(奥側)に位置するように温熱具本体12を配置すれば、温熱具本体12の高さは手前側が低くなり奥側が高くなる。よって、本等を温熱具本体12の外表面にもたれかけさせると紙面が身体側に向くように本等が傾き鑑賞しやすくなる。また、筒状にした温熱具本体12内部に手を挿入したとき、温熱具本体12の内面においても手前側が低くなり奥側が高くなるので、温熱具本体12に挿入された手の位置を安定させることができる。   The edge 13 (both ends 12c and 12d in the short direction) on the extension line of the second stitches 18a to 18h is not delimited by the second stitches 18a to 18h. In this state, it is possible to swell in the thickness direction of the heating tool body 12 closer to the both ends 12c and 12d of the heating tool body 12 than to the center of the heating tool body 12. Therefore, many heat insulating members 14 are accommodated near the both end portions 12c and 12d of the heating tool main body 12, and the thickness of the heating tool main body 12 is larger than both end portions 12c and 12c of the heating tool main body 12 than the center of the heating tool main body 12. The one closer to 12d becomes larger. Therefore, when the heating tool body 12 is folded at the center of the heating tool body 12 during use and the both ends 12c and 12d of the heating tool body 12 are overlapped to make the heating tool body 12 cylindrical, the thickness of the heating tool body is as follows. The side where 12 both ends 12c and 12d are overlapped is larger than the other (the folded side). If the heating tool body 12 is arranged so that the thicker one of the heating tool body 12 is positioned on the outer side (back side) with respect to the body, the height of the heating tool body 12 becomes lower on the near side and higher on the back side. Therefore, when the book or the like is leaned against the outer surface of the heating tool body 12, the book or the like can be easily tilted and viewed so that the paper surface faces the body. Further, when the hand is inserted into the cylindrical heating tool body 12, the front side is lowered and the back side is also raised on the inner surface of the heating tool body 12, so that the position of the hand inserted into the heating tool body 12 is stabilized. be able to.

温熱具本体12を展開した状態において、第1ステッチ16の一端は温熱具本体12の長手方向端部12bに至らず、第2ステッチ18a〜18hのそれぞれの両端は温熱具本体12の短手方向両端部12c,12dに至らないので、温熱具本体12の内部は1つの空間として繋がっている。したがって、断熱部材14を温熱具本体12に供給する際には、図1において一点鎖線の矢印Xで示すように、断熱部材14は温熱具本体12の縁部13を通って温熱具本体12内の全域に移動可能であるので、一箇所の断熱部材収容口22から温熱具本体12内の全域に断熱部材14を供給できる。   In the state where the heating tool body 12 is unfolded, one end of the first stitch 16 does not reach the longitudinal end portion 12b of the heating tool body 12, and both ends of the second stitches 18a to 18h are in the short direction of the heating tool body 12. Since it does not reach both ends 12c and 12d, the inside of the heating tool main body 12 is connected as one space. Therefore, when the heat insulating member 14 is supplied to the heating tool main body 12, the heat insulating member 14 passes through the edge 13 of the heating tool main body 12 in the heating tool main body 12 as shown by a dashed line arrow X in FIG. Therefore, the heat insulating member 14 can be supplied from one heat insulating member accommodation port 22 to the entire area inside the heating tool main body 12.

第1ステッチ16と第2ステッチ18a〜18hとの交差角を直角または略直角にすることで、第1ステッチ16と第2ステッチ18a〜18hとの交差箇所付近にも断熱部材14を供給しやすくなり、さらに安定した保温効果を得ることができる。   By making the crossing angle of the first stitch 16 and the second stitches 18a to 18h at right angles or substantially right angles, it is easy to supply the heat insulating member 14 near the crossing points of the first stitch 16 and the second stitches 18a to 18h. Thus, a more stable heat retaining effect can be obtained.

温熱具本体12の中央付近の厚みは温熱具本体12の軸方向両端側の厚みよりも大きく、筒状に形成された温熱具本体12の内部空間は、温熱具本体12の軸方向両端側では広くなり、温熱具本体12の中央付近では狭くなる。この実施形態では、温熱具本体12の中央付近では、温熱具本体12同士が接触する。したがって、使用時において、筒状に形成された温熱具本体12の軸方向両端から手を挿入しやすく、手を温熱具本体12の中央付近まで挿入すると、手が温熱具本体12と密着し、高い保温効果が得られる。また、手を温熱具本体12の中央付近まで挿入するだけで温熱具本体12と手とが密着することから、温熱具本体12を保持することが容易になる。温熱具本体12の矢印Sで示す短手方向の伸縮率を大きくすることによって、筒状に形成された温熱具本体12はその径方向に伸縮容易になるので、温熱具本体12と手とはさらに密着し易くなる。   The thickness in the vicinity of the center of the heating tool body 12 is larger than the thickness at both axial ends of the heating tool body 12, and the internal space of the heating tool body 12 formed in a cylindrical shape is at both axial ends of the heating tool body 12. It becomes wider and becomes narrow near the center of the heating tool body 12. In this embodiment, the heating tool bodies 12 are in contact with each other near the center of the heating tool body 12. Therefore, in use, it is easy to insert a hand from both axial ends of the heating tool body 12 formed in a cylindrical shape, and when the hand is inserted to the vicinity of the center of the heating tool body 12, the hand is in close contact with the heating tool body 12, High heat retention effect is obtained. Moreover, since the heating tool main body 12 and the hand are in close contact by simply inserting the hand to the vicinity of the center of the heating tool main body 12, the heating tool main body 12 can be easily held. By increasing the expansion / contraction ratio in the short direction indicated by the arrow S of the heating tool main body 12, the heating tool main body 12 formed in a cylindrical shape can be easily expanded and contracted in the radial direction. Furthermore, it becomes easy to adhere.

ファスナ20によって温熱具本体12を筒状に保持でき、手用温熱具10を手のケアのために使用できる。また、温熱具本体12を展開した状態では、手用温熱具10を膝掛けや座布団等としても使用することが可能である。このように、手用温熱具10は、手をケアするだけではなく様々な用途を有する。さらに、ファスナ20の取扱いは簡単であるため、使用時に温熱具本体12を筒状に保持することが容易である。   The heater 20 can be held in a cylindrical shape by the fastener 20, and the hand warmer 10 can be used for hand care. In addition, in the state where the heating tool body 12 is deployed, the hand heating tool 10 can be used as a lap or a cushion. Thus, the hand warmer 10 has various uses as well as care for the hand. Furthermore, since the fastener 20 is easy to handle, it is easy to hold the heating tool body 12 in a cylindrical shape during use.

温熱具本体12は、弾力性が高くかつ吸水性が低いという特徴を有するポリエステルからなるので、温熱具本体12を誤って落下させてしまっても破損する可能性は低く、また、濡れても乾きやすく、取扱いが容易である。   Since the heating tool body 12 is made of polyester having the characteristics of high elasticity and low water absorption, it is unlikely to be damaged even if the heating tool body 12 is accidentally dropped. Easy to handle.

断熱部材14は、断熱効果が高くかつ吸水性が低いという特徴を有する発泡部材からなるので、体温を逃がさず高い保温効果を得ることができ、また、吸水による劣化はし難く長期間にわたり断熱効果を保つことができる。   Since the heat insulating member 14 is made of a foamed member having a high heat insulating effect and low water absorption, a high heat retaining effect can be obtained without escaping body temperature, and the heat insulating effect is difficult to deteriorate due to water absorption over a long period of time. Can keep.

温熱具本体12がポリエステルからなりかつ断熱部材14が発泡部材からなるので、筒状に形成された手用温熱具10の内部と外部との通気性を保つことができる。   Since the heating tool main body 12 is made of polyester and the heat insulating member 14 is made of a foamed member, the air permeability between the inside and the outside of the hand-made heating tool 10 formed in a cylindrical shape can be maintained.

筒状の手用温熱具10は、たとえば、枕やクッション等としても使用できる。   The tubular hand warmer 10 can be used as, for example, a pillow or a cushion.
