Description

【０００１】
【発明の属する技術分野】
本発明は、可撓性シート体によって形成された内部に飲料や食品、薬品等の液体や粘体等が充填される袋状の容器本体に取り付けられる容器用口部材の改良に関する。
【０００２】
【従来の技術】
近年、図７に示すような、合成樹脂フィルムとアルミホイル等のラミネートシート等の可撓性を有するシート体の縁部をヒートシールすることによって形成される袋状の容器21が飲料、食品、薬品等の液体や粘体を被充填物として充填する容器として使用されているが、該容器21には通常上端縁部21a に合成樹脂から成形された別体の口部材20がヒートシール等の取付け手段によって取り付けられている。
【０００３】
この口部材20は、容器21と周面がシールされる取付台部14と該取付台部14の中央部に突設された容器21内部の飲料等が注出可能な注出口13a が形成された注出部13とからなる取付部12と、該取付部12の下方に延設されたストロー状の棒状体15から形成されている。
尚、前記取付部12の注出部13には注出口部13a を密封するために蓋体16が冠着されている。
【０００４】
棒状体15は容器21内の被充填物の残量が少ない場合に、シート体からなる容器21の前後のシート体同士が密着して、被充填物が取り出しにくくなることを防止すると同時に、上記注出部13に直接口を着けて被充填物を注出口部13a から吸い出す場合にはストローとしての役割も果たす。
【０００５】
【発明が解決しようとする課題】
このような口部材20は、通常、射出成形等の一体成形によって形成されているが、上記のように口部材20の取付部12は凹凸が多い複雑な形状である上に、細長く且つ内部が空洞であるストロー状の棒状体15も一体に成形しなければならず、その成形型の形状が複雑にならざる得なかった。
【０００６】
特に、該ストロー状の棒状体15を成形する場合には、棒状体15の周壁を形成するための外枠と内部の開口部を形成するための細長いピン部材からなる成形型を使用して、外枠の内部にピン部材を嵌め込んだ該成形型内に樹脂を射出して成形するが、複雑な形状の取付部用の成形型内及び細長く薄いパイプ状の型内に同時に樹脂を充填しなければならないため、樹脂が隅々まで充填されるまでに時間がかかり、またこのような樹脂を成形後に冷却して成形品として取り出すにも時間がかかり成形効率が悪いという問題があった。
【０００７】
また、成形用のピン部材と外枠、及び取付部用の成形型がそれぞれ多数連結され一度に複数個を成形する型の場合には各成形型部分を正確な位置に誤差なく嵌め合わせることが難しく、この嵌め合わせがずれた場合等に細長いピン部材が折れたりするおそれがある。
従って、１つの金型で一度に成形できる口部材の数には限度があり（通常１６個程度）、大量に成形することが困難であった。
【０００８】
また、取付部12の大きさや厚み等は取り付ける容器や被充填物等によって変更する必要があり、或いは棒状体15を使用せずに取付部12のみを容器に取り付ける場合や、また棒状体15の長さや太さ、形状も容器の大きさや被充填物によって変更する必要がある。
従って、このような口部材20の設計変更の度に成形型全体を作り直さなければならなかった。
【０００９】
【課題を解決するための手段】
本発明は、このような問題点を解決するためになされたもので、大量生産が容易な経済的な容器用口部材を提供することを課題とする。
【００１０】
本発明が、このような課題を解決するためになされた手段としては、可撓性シート体からなる容器にヒートシールにより取り付けられる口部材本体１を備え、該口部材本体１は、空間部４ａが形成されて容器にヒートシールされる取付台部４を有する取付部２と、該取付部２とは別体として形成されて取付部２の下方に延設するように取り付けられた棒状体３とからなり、取付台部４の空間部４ａ内には嵌合溝７を有する支持板６が一体に形成され、棒状体３の上部には嵌合突起８が形成され、棒状体３の嵌合突起８を取付部２における支持板６の嵌合溝７に嵌合させることによって取付部２に棒状体３が取り付けられる構成とされていることにある。
【００１１】
また、別の手段としては、棒状体３が断面略十字形状であってその上部中央部分には切り欠き１１が形成され、取付部２の支持板６に棒状体３の切り欠き１１を係合させることによって取付部２に棒状体３が取り付けられる構成とされていることにある。
また、別の手段としては、可撓性シート体からなる容器にヒートシールにより取り付けられる口部材本体１を備え、該口部材本体１は、空間部４ａが形成されて容器にヒートシールされる取付台部４と該取付台部４から上方に立設されて注出口部５ａが前記空間部４ａと連通する注出部５とを有する取付部２と、該取付部２とは別体として成形されて取付部２の下方に延設するように取り付けられた棒状体３とからなり、注出口部５ａから棒状体３の下端を挿入して取付部２の空間部４ａ内の嵌合溝７に棒状体３の上部の嵌合突起８を嵌合させることによって取付部２に棒状体３が取り付けられる構成とされていることにある。
【００１２】
すなわち、本発明の容器用口部材は、取付部2 と、該取付部2 の下方に延設された棒状体3 を別体として成形し、該取付部2 と棒状体3 を嵌合あるいは係合によって取り付けることによって口部材本体1 を形成するため、取付部2 と棒状体3 を成形する際に、従来のように複雑な形状の成形型を使用する必要がなく、成形作業の効率が向上するとともに一度に多量の成形を行っても成形型が損傷したり成形不良が生じるおそれがない。
【００１３】
また、成形型の形状が複雑ではないため、形成型内に樹脂等を射出する場合にも短時間で樹脂を完全に充填することができ、また、成形樹脂を冷却する時間も短縮できる。
【００１４】
【発明の実施の形態】
以下、本発明の実施の形態の一例を図面を参照しながら説明する。
まず、図１に示す１は合成樹脂から成形された口部材本体で、該口部材本体１は、可撓性シート体からなる容器にヒートシール等によって取り付けられる取付台部４を有する取付部２と、該取付部２とは別体として成形され空洞部3aを有するストロー状の棒状体３が取付け部を介して連結されている。
【００１５】
口部材本体１の材質は一般的に成形材料として使用されるポリプロピレンやポリエチレン等、任意の合成樹脂が使用できるが、取り付ける容器にヒートシール等によって取付け可能な樹脂であることが必要である。
【００１６】
4aは前記取付台部４内に形成された空間部で、該空間部4a内の両側位置には図１及び図２（イ）に示すように一対の支持板６が一体に形成されている。５は該取付台部４の中央部に立設された注出口部5aを有する注出部で、該注出部５の注出口部5aと前記空間部4a及び棒状体３の空洞部3aは連通されている。７は、該支持板６の対向位置に形成された嵌合溝である。
【００１７】
８は、図１及び図２（イ）（ロ）に示すように前記棒状体３の上部両側に外向きに突設された嵌合突起で、該嵌合突起８は前記取付部２の空間部4aに形成された嵌合溝７に嵌合されることによって取付部２と棒状体３が連結されている。
また、この嵌合突起８及び嵌合溝７は、容易に抜けない形状に形成されている。
尚、この嵌合溝７と嵌合突起８から取付け手段が形成されている。
【００１８】
上記のような構成からなる容器用口部材10を製造する場合には、まず取付部２と棒状体３をそれぞれ別の成形型によって成形する。
【００１９】
従って、複雑な形状の取付部２と、細長い形状の棒状体３の両方の形を有する金型を嵌め合わせる必要がないため、多数の金型を連結して一度に多数の成形を行うようにしても、金型の嵌め合わせ時にずれ等が生じにくく、成形不良や金型に損傷等が生じにくい。
【００２０】
また、各成形部材は小型であるため、金型内に樹脂を充填する場合に短時間で充填することができ、且つ冷却も短時間で行えるため、成形時間を短縮できる。
【００２１】
特に、棒状体３を成形する場合には空洞部3aを形成するために細長いピン部材が外枠の内部に挿入された金型を使用するが、このような金型と上記取付部２のような複雑な形状の金型を一体として取り付けた金型により成形を行う場合には金型を合わせる際に誤差が生じるとピン部材が外枠内に挿入されなかったり、装置の振動や離型する時の力等で折れるおそれがある。
しかし、上記のように棒状体３のみを個別に成形するため、このような問題が生じにくく多数の棒状体３を一度に成形することができる。
【００２２】
次に、図３に示すようにそれぞれ別体として成形された棒状体３と取付部２を連結するが、まず、前記取付部２側の空間部4a内に棒状体３の上端部を下方から挿入する。
そして、空間部4a内部に形成された支持板６の嵌合溝７に、棒状体３の上端部に突設された嵌合突起８を嵌合して、棒状体３と取付部２を連結し、口部材本体１が形成され、さらに、注出部５の上部は、容器に口部材本体１を取り付けて被充填物を充填した後に蓋体（図示セズ）を冠着できるように形成されている。
【００２３】
この容器用口部材10を、例えば可撓性シート体からなる飲料等用の容器に取付ける場合には、前記取付台部４の周面を容器の上端部の内面側とヒートシールすることによって簡単に取り付けることができる。
【００２４】
該容器の飲料等は、容器内に上下方向に収納された棒状体３の空洞部3a及び取付台部４の空間部4aを介して注出口部5aから注ぎ出したり、或いは注出部５に直接口を着けて吸い出すことができる。
【００２５】
この時、棒状体３はストローとして働くと同時に、容器内の飲料等の被収納物が残り少なくなった時に、容器を形成する可撓性シート体の内面同士が密着して被収納物が吸い出しにくくなることを防止でき、被収納物が残り少なくなった場合にも最後まで確実に取り出すことができる。
【００２６】
さらに、例えば、別の容器において容器用口部材10を使用する場合に、棒状体３は同じ型のものを使用するが取付部２は大きさ等を変更したい場合や、或いは逆に取付部２はそのまま使用するが被充填物によって棒状体３の形状等を変更したい場合等には、取付部２のみ又は棒状体３のみを他の成形型を使用して製造すればよく、成形型の全体を変更する必要がない。
【００２７】
尚、上記実施の形態では、棒状体３は空洞部3aを有するストロー状に形成したが、棒状体の形状はこれに限定されるものではなく、図４（イ）に示すように断面視が略Ｎ字状や、図４（ロ）に示すような周面に突起が形成されたもの、あるいは図４（ハ）に示すような一対の板状体からなる棒状体等、要は上部が取付部２に取付け可能に形成され、且つ容器内の被収納物の残量が少なくなった時に容器を形成するシート体が密着して取り出しにくくなることを防止できるような棒状体であればどのような形状のものでもよい。
【００２８】
また、上記実施の形態では、取付部２と棒状体３を取付ける取付け手段として、取付部２内の空間部4a内に形成された嵌合溝７と、棒状体３の上部に突設された嵌合突起８から形成したが、取付け手段としてはこれに限定されるものではない。
【００２９】
例えば、図５（イ）に示すような断面が略十字形状で且つ上部中央部分に切り欠き11を形成した棒状体３を、図５（ロ）に示すような取付部２の空間部4a内に形成された支持板６に図５（ロ）の点線に示すように前記切り欠き11を係合させることによって取付部２と棒状体３を取り付けてもよい。
【００３０】
この他、ネジ止め等を取付け手段としてもよく、要は、別体として成形された取付部２と棒状体３を後から取付けることができる手段が形成されていればよい。
【００３１】
さらに、上記実施の形態では、棒状体３を取付部２に取り付ける際に、空間部4aの下方から棒状体３を挿入して取り付けたが、例えば図６に示すように、取付部２の注出部５から棒状体３の下端を挿入してそのまま下方に移動させて、取付部２の空間部4a内に形成された嵌合溝７内に棒状体３の上部の嵌合突起８を嵌合させることによって棒状体３を取付部２に取り付けてもよい。この場合には、注出口部5aの内径が棒状体３の上部の外径よりも大きく形成されることが必要である。
【００３２】
また、上記実施の形態では、容器用口部材を容器の上端部に取り付ける場合について説明したが、容器用口部材は容器の上端部に取り付けられることは条件ではなく、容器の側部や前面部等に取り付けてもよい。
この場合には棒状体３の形状を容器に収納可能なように任意に変形させることができる。
【００３３】
【発明の効果】
叙上のように、本発明は、容器用口部材の成形作業の効率化を図り簡単且つ経済的に容器用口部材を大量生産することができる。
また、容器の設計変更に合わせて容器用口部材の設計変更も容易且つ経済的にできる。

BACKGROUND OF THE INVENTION
The present invention relates to an improvement in a container mouth member attached to a bag-shaped container body in which a liquid, a viscous material, or the like such as a beverage, food, or medicine is filled in an interior formed by a flexible sheet body.
[0002]
[Prior art]
In recent years, as shown in FIG. 7, a bag-like container 21 formed by heat-sealing the edge of a flexible sheet body such as a laminate sheet such as a synthetic resin film and aluminum foil is used for beverages, foods, It is used as a container that fills liquids such as chemicals and viscous substances as filling materials, but the container 21 is usually provided with a separate mouth member 20 molded from a synthetic resin at the upper edge 21a, such as a heat seal. Attached by means.
[0003]
The mouth member 20 is formed with a mounting base part 14 whose peripheral surface is sealed with the container 21, and a spout 13a which can be poured out of the beverage inside the container 21 protruding from the central part of the mounting base part 14. It is formed of a mounting portion 12 composed of a pouring portion 13 and a straw-like rod-like body 15 extending below the mounting portion 12.
A lid 16 is attached to the extraction portion 13 of the mounting portion 12 to seal the outlet portion 13a.
[0004]
When the remaining amount of the filling material in the container 21 is small, the rod-shaped body 15 is in close contact with the front and rear sheet bodies of the container 21 made of the sheet body, and at the same time prevents the filling material from becoming difficult to take out. When a mouth is directly attached to the pouring part 13 and the filling material is sucked out from the pouring part 13a, it also serves as a straw.
[0005]
[Problems to be solved by the invention]
Such a mouth member 20 is usually formed by integral molding such as injection molding, but the mounting portion 12 of the mouth member 20 has a complicated shape with many irregularities as described above, and is elongated and has an inner portion. The hollow straw-like body 15 that is a hollow must also be integrally molded, and the shape of the molding die has to be complicated.
[0006]
In particular, when the straw-shaped rod-shaped body 15 is molded, a molding die composed of an outer frame for forming the peripheral wall of the rod-shaped body 15 and an elongated pin member for forming an internal opening is used. The resin is injected into the mold with the pin member fitted inside the outer frame and molded, but the resin is filled into the mold for the mounting part with a complicated shape and into a long and thin pipe-shaped mold at the same time. Therefore, there is a problem that it takes time until the resin is filled to every corner, and it takes time to cool such resin after molding and take it out as a molded product, resulting in poor molding efficiency.
[0007]
In addition, in the case of a mold in which a large number of molding pin members, outer frames, and molds for attachment portions are connected to form a plurality at a time, each mold part can be fitted to an accurate position without error. It is difficult, and there is a possibility that the elongated pin member may be broken when the fitting is displaced.
Therefore, there is a limit to the number of mouth members that can be molded at one time with one mold (usually about 16), and it has been difficult to mold in large quantities.
[0008]
In addition, the size and thickness of the mounting portion 12 need to be changed depending on the container to be filled, the object to be filled, etc., or when only the mounting portion 12 is mounted on the container without using the rod-shaped body 15, or The length, thickness, and shape also need to be changed depending on the size of the container and the filling material.
Therefore, the entire mold must be remade every time the design of the mouth member 20 is changed.
[0009]
[Means for Solving the Problems]
The present invention has been made to solve such problems, and an object thereof is to provide an economical container mouth member that can be easily mass-produced.
[0010]
As means for solving the above-mentioned problems, the present invention includes a mouth member main body 1 that is attached to a container made of a flexible sheet by heat sealing, and the mouth member main body 1 has a space portion 4a. And a mounting portion 2 having a mounting portion 4 that is heat-sealed to the container, and a rod-shaped body 3 that is formed separately from the mounting portion 2 and is attached to extend below the mounting portion 2. A support plate 6 having a fitting groove 7 is integrally formed in the space 4 a of the mounting base 4, and a fitting protrusion 8 is formed on the upper part of the rod-shaped body 3. The mating protrusion 8 is fitted in the fitting groove 7 of the support plate 6 in the attachment portion 2, whereby the rod-shaped body 3 is attached to the attachment portion 2 .
[0011]
Further, as another means, the rod-shaped body 3 has a substantially cross-shaped cross section, and a notch 11 is formed in the upper central portion thereof, and the notch 11 of the rod-shaped body 3 is engaged with the support plate 6 of the mounting portion 2. By doing so, the rod-like body 3 is attached to the attachment portion 2 .
As another means, the mouth member main body 1 is attached to a container made of a flexible sheet body by heat sealing, and the mouth member main body 1 is attached to be heat sealed to the container by forming the space portion 4a. A mounting part 2 which has a base part 4 and a pouring part 5 which stands up from the mounting base part 4 and whose spout part 5a communicates with the space part 4a is molded separately from the mounting part 2. And the fitting groove 7 in the space part 4a of the attachment part 2 by inserting the lower end of the rod-like body 3 from the spout part 5a. This is because the rod-like body 3 is attached to the attachment portion 2 by fitting the fitting protrusions 8 on the upper portion of the rod-like body 3 to each other.
[0012]
That is, the container mouth member of the present invention is formed by separately forming the attachment portion 2 and the rod-like body 3 extending below the attachment portion 2, and fitting or engaging the attachment portion 2 and the rod-like body 3. Since the mouth member body 1 is formed by mounting together, it is not necessary to use a mold having a complicated shape as in the conventional case when forming the mounting portion 2 and the rod-shaped body 3, and the efficiency of the molding work is improved. In addition, even if a large amount of molding is performed at one time, there is no possibility that the mold is damaged or defective molding occurs.
[0013]
Further, since the shape of the mold is not complicated, even when the resin or the like is injected into the mold, the resin can be completely filled in a short time, and the time for cooling the mold resin can be shortened.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings.
First, reference numeral 1 shown in FIG. 1 denotes a mouth member main body molded from a synthetic resin. The mouth member main body 1 has an attachment portion 2 having an attachment base portion 4 attached to a container made of a flexible sheet by heat sealing or the like. And the straw-shaped rod-shaped body 3 which is molded separately from the mounting portion 2 and has a hollow portion 3a is connected via the mounting portion.
[0015]
The material of the mouth member main body 1 can be any synthetic resin such as polypropylene or polyethylene, which is generally used as a molding material. However, the mouth member main body 1 needs to be a resin that can be attached to a container to be attached by heat sealing or the like.
[0016]
Reference numeral 4a denotes a space formed in the mounting base 4, and a pair of support plates 6 are integrally formed at both side positions in the space 4a as shown in FIGS. . 5 is a spout portion having a spout portion 5a erected on the central portion of the mounting base portion 4, spout 5a and the space 4a and the cavity 3a of the rod-shaped body 3 of the noted output section 5 It is communicated. Reference numeral 7 denotes a fitting groove formed at a position facing the support plate 6.
[0017]
1 and 2 (A) and (B), 8 are fitting protrusions projecting outward on both sides of the upper portion of the rod-shaped body 3, and the fitting protrusion 8 is a space of the mounting portion 2. As shown in FIG. The mounting portion 2 and the rod-shaped body 3 are connected by being fitted into the fitting groove 7 formed in the portion 4a.
Further, the fitting protrusion 8 and the fitting groove 7 are formed in a shape that does not easily come off.
The fitting means is formed by the fitting groove 7 and the fitting projection 8.
[0018]
In the case of manufacturing the container mouth member 10 having the above-described configuration, first, the attachment portion 2 and the rod-shaped body 3 are formed by separate molding dies.
[0019]
Accordingly, since it is not necessary to fit the molds having both the shape of the mounting portion 2 having a complicated shape and the elongated rod-shaped body 3, a large number of molds are connected to perform a large number of moldings at once. However, a shift or the like hardly occurs at the time of fitting the molds, and molding defects or damage to the molds hardly occur.
[0020]
In addition, since each molded member is small, when the resin is filled in the mold, it can be filled in a short time and can be cooled in a short time, so that the molding time can be shortened.
[0021]
In particular, when the rod-shaped body 3 is formed, a mold in which an elongated pin member is inserted into the outer frame is used to form the cavity 3a. When molding is performed using a mold with a complicated and complicated shape, the pin member may not be inserted into the outer frame, or the device may vibrate or release when there is an error when aligning the mold. There is a risk of breaking with the power of time.
However, since only the rod-shaped bodies 3 are individually molded as described above, such a problem is unlikely to occur and a large number of rod-shaped bodies 3 can be molded at a time.
[0022]
Next, as shown in FIG. 3, the rod-shaped body 3 and the mounting portion 2 which are formed as separate bodies are connected to each other. First, the upper end portion of the rod-shaped body 3 is inserted into the space portion 4a on the mounting portion 2 side from below. insert.
Then, a fitting protrusion 8 projecting from the upper end of the rod-like body 3 is fitted into the fitting groove 7 of the support plate 6 formed in the space 4a, and the rod-like body 3 and the mounting portion 2 are connected. In addition, the mouth member body 1 is formed, and the upper portion of the pouring part 5 is formed so that the lid body (sew shown in the figure) can be crowned after the mouth member body 1 is attached to the container and the object to be filled is filled. ing.
[0023]
When the container mouth member 10 is attached to a container for beverages or the like made of, for example, a flexible sheet body, it is easy to heat-seal the peripheral surface of the mounting base 4 with the inner surface of the upper end of the container. Can be attached to.
[0024]
The beverage or the like in the container is poured out from the spout part 5a through the hollow part 3a of the rod-shaped body 3 and the space part 4a of the mounting base part 4 stored in the container in the vertical direction, or is poured into the spout part 5. It can be sucked out directly from the mouth.
[0025]
At this time, the rod-shaped body 3 functions as a straw, and at the same time, when the stored items such as beverages in the container are reduced, the inner surfaces of the flexible sheet members forming the container are in close contact with each other and the stored items are difficult to suck out. It can be prevented, and even when there are few remaining items to be stored, it can be reliably taken out to the end.
[0026]
Further, for example, when the container mouth member 10 is used in another container, the rod-shaped body 3 is of the same type, but the mounting portion 2 is to be changed in size, or conversely, the mounting portion 2. Is used as it is, but when it is desired to change the shape or the like of the rod-shaped body 3 depending on the object to be filled, only the mounting portion 2 or only the rod-shaped body 3 may be manufactured using another mold. There is no need to change.
[0027]
In the above embodiment, the rod-shaped body 3 is formed in a straw shape having the hollow portion 3a. However, the shape of the rod-shaped body is not limited to this, and as shown in FIG. In general, the upper part, such as a substantially N-shape, a protrusion formed on the peripheral surface as shown in FIG. 4 (B), or a rod-like body consisting of a pair of plate-like bodies as shown in FIG. Any rod-shaped body that can be attached to the mounting portion 2 and that can prevent the sheet body forming the container from coming into close contact and becoming difficult to take out when the amount of the contents to be stored in the container decreases. Such a shape may be used.
[0028]
Moreover, in the said embodiment, as the attachment means which attaches the attachment part 2 and the rod-shaped body 3, it was provided in the upper part of the fitting groove 7 formed in the space part 4a in the attachment part 2, and the rod-shaped body 3. Although formed from the fitting protrusion 8, the attaching means is not limited to this.
[0029]
For example, a rod-like body 3 having a substantially cross-shaped cross section as shown in FIG. 5 (a) and a notch 11 formed in the upper central portion is provided in the space 4a of the mounting portion 2 as shown in FIG. 5 (b). The attachment portion 2 and the rod-like body 3 may be attached by engaging the notch 11 with the support plate 6 formed in FIG. 5 as shown by the dotted line in FIG.
[0030]
In addition, screwing or the like may be used as the attaching means. In short, it is only necessary to form means capable of attaching the attaching portion 2 and the rod-like body 3 formed separately as later.
[0031]
Furthermore, in the above embodiment, when attaching the rod-shaped body 3 to the mounting portion 2, the rod-shaped body 3 is inserted from below the space portion 4a and mounted. However, as shown in FIG. The lower end of the rod-shaped body 3 is inserted from the protruding portion 5 and moved downward, and the fitting protrusion 8 on the upper portion of the rod-shaped body 3 is fitted into the fitting groove 7 formed in the space portion 4a of the mounting portion 2. You may attach the rod-shaped body 3 to the attachment part 2 by making it match. In this case, the inner diameter of the spout portion 5a needs to be larger than the outer diameter of the upper portion of the rod-shaped body 3.
[0032]
In the above embodiment, the case has been described in which the container mouth member is attached to the upper end of the container. However, it is not a condition that the container mouth member is attached to the upper end of the container. You may attach to etc.
In this case, the shape of the rod-shaped body 3 can be arbitrarily changed so as to be housed in the container.
[0033]
