Description

  The present invention relates to a structure of a portable pouch for storing a beverage container or the like, and more particularly to a structure of a portable pouch in which a bottom portion of a storage portion such as a beverage container or the like is formed of a resin member.

  Recently, various types of portable beverage containers in which a stainless steel container having a heat insulating structure is configured as a drink bottle or a soup cup have been provided.

  And in such a beverage container, in order to protect the damage at the time of carrying and to make it easy to carry, a portable pouch (water bottle cover) for storing a beverage container etc. according to the shape and dimensions of the beverage container. In general, the user stores the beverage container or the like in the pouch and carries it.

  Conventionally, this portable pouch for storing beverage containers or the like is composed of a cloth cylindrical portion that forms the storage portion main body and a cloth dish-shaped portion that forms the bottom of the cylindrical portion.

  And since this type of portable pouch is used for a long period of time, for example, by hand, or stored in a bag as needed, it is possible to maintain the shape, friction and impact. Resistant to damage caused by For this reason, the cloth member has a relatively high rigidity and is thick.

  However, adults often walk while dragging the ground with straps with longer dimensions in the case of heels and corners, and in such cases, damage due to friction at the bottom (corner) is particularly severe.

  For this reason, some products employ a three-dimensional molding structure in which a synthetic resin material is molded into a dish-shaped portion that forms the bottom of the pouch.

  However, simply molding a synthetic resin material on a cloth-made bottom member has a limit in improving the strength, and cracks and the like are assumed.

  Therefore, for example, the main body portion is a cloth member as used in a conventional handbag, but the bottom portion may be composed of a non-fabric member such as a synthetic resin plate (a publicly known handbag using the same structure). For example, see the configurations of Patent Document 1 and Patent Document 2, for example).

  In the portable pouch for storing the beverage container or the like, if such a configuration is adopted, the strength of the bottom portion of the pouch can be sufficiently improved, and the above-described problems are solved.

No. 6-4734 Utility Model Registration No. 3003575

  By the way, as described above, the main body part is a cloth member, but when the bottom part is composed of a non-fabric member such as a synthetic resin member, it is a problem how to connect them together. Become.

  Although the technical field is different from the portable pouch for storing beverage containers, etc., in the case of the handbag of the above-mentioned Patent Document 1, a flexible ring-shaped synthetic resin pipe is sewn into the lower end of the cloth body to form a convex portion. These are fixed and integrated by sandwiching them using a frame member on the lower surface side of the flange-shaped flange portion formed on the outer periphery of the opening of the bottom member made of synthetic resin.

  However, in such a configuration, when the frame member is detached, the bottom member is separated, which is not a reliable connection structure. In addition, many components such as a pipe member, a flange portion, and a frame member are required, and the dimensions of the connecting portion are partially increased, resulting in a great design restriction.

  On the other hand, in the case of the above-mentioned Patent Document 2, there is no problem as in the case of the above-mentioned Patent Document 1, but by making an elastic ring such as a rubber band at the end of the cloth body member, the tea width can be drawn. They are simply integrated by placing the bottom plate made of a synthetic resin, drawing the width of the tea, and thermally fusing the periphery to the bottom surface of the bottom plate.

  Therefore, the outer peripheral surface of the bottom plate is also a cloth member, and the bottom corner portion is easily torn, and does not solve the problem of the conventional portable pouch.

  The present invention was made in order to solve such problems, and in a portable pouch in which a bottom member made of a resin material is provided at the lower end of a storage body main body made of a cloth member, the storage portion of the bottom member It is an object of the present invention to provide a portable pouch that solves the above-described conventional problems by allowing a part of the side wall corresponding to the main body to be sewn and integrating the bottom member with the storage body. .

In order to solve the above-described problems, the present invention includes the following problem solving means.
(1) First Problem Solving Means In the present invention, as a first problem solving means for solving the above problems, a beverage comprising a bottom member made of a resin material at the lower end of a storage body body made of a cloth member. In a portable pouch for storing a container or the like, the thickness of the inner peripheral surface side of the upper side predetermined width portion of the side wall corresponding to the storage portion body of the bottom member is made thinner than the lower side portion, and a sewing tape is used. The sewing unit is integrated with the lower end of the storage body.

  In the case of such a configuration, unlike the conventional case where the synthetic resin is molded only on the cloth bottom member, the bottom member is entirely made of a resin material, so that it has sufficient strength. Is expensive.

In addition, the side wall upper part, which is the connecting part corresponding to the housing part main body of the bottom member, is formed so that the inner peripheral surface side is thinner than the lower part and can be sewn through the sewing needle. Since it is formed in a simple structure portion, it can be effectively sewn to the lower end portion of the storage portion main body.

  When making the upper side portion of the side wall, which is the connecting portion of the bottom member with respect to the storage unit main body, into a structure that can be sewn through the sewing needle, the material of the bottom member side wall portion should be partially low in hardness, It is conceivable to form pores corresponding to perforations in advance, but in any case, the processing is complicated and the cost increases.

However, as described above, if a structure in which the thickness on the inner peripheral surface side of the upper predetermined width portion corresponding to the storage portion main body on the side wall of the bottom member is made thinner than the thickness of the lower side portion, molding is easy, No special processing is required and sewing can be performed at low cost.

Further, in the case of the configuration of this problem solving means, the upper side predetermined width portion whose inner peripheral surface side is thinner than the lower side portion of the side wall of the bottom member eliminates the step inside the sewing tape. And after forming the flush contact surface inside the said side wall, it is sewn on the lower end part of the said accommodating part main body. Accordingly, the binding force of the sewing portion is improved as compared with the case where the upper predetermined width portion having a small thickness on the inner peripheral surface side of the bottom member side wall is directly sewn to the storage portion main body.

  As a result, the cloth storage unit main body and the resin bottom member are firmly connected and integrated, and the bottom of the portable pouch for storing a beverage container or the like is durable against long-term use.

(2) Second Problem Solving Means In the present invention, as a second problem solving means for solving the above problems, the sewing tape in the first problem solving means is folded in both the inner and outer directions at the center in the width direction. In addition, it is characterized in that the upper side predetermined width portion thinner than the lower side portion of the bottom member side wall is stitched and integrated.
Thus, when the upper side predetermined width portion having a thickness smaller than the lower side portion of the side wall of the bottom member is sewn to the lower end portion of the storage portion main body via the sewing tape, the sewing tape is When folded in both the inner and outer directions at the center in the width direction and stitched and integrated with the upper predetermined width portion that is thinner than the lower side portion of the bottom member side wall, the folded portion of the sewing tape is more than the lower side portion. In addition, it fills the step with the lower part of the predetermined width part on the upper side, making the thickness thinner, facilitating sewing with the lower part of the storage unit body, and covering the connection between the bottom member side wall and the storage unit body part So it looks better.

(3) Third Problem Solving Means In the present invention, as a third problem solving means for solving the above problems, the thickness of the corner portion of the bottom member in the first or second problem solving means is as follows: It is characterized in that it is formed thicker than the part.

The corners of the bottom member are required to have the highest strength. Therefore, when the thickness of the corner (corner) of the bottom member is formed to be thicker than that of the other parts, it is possible to appropriately respond to the request.
(4) Fourth Problem Solving Means In the present invention, as a fourth problem solving means for solving the above problems, the bottom surface of the bottom member in the first, second or third problem solving means has a convex shape. It is characterized by providing leg parts.

  As described above, when a plurality of convex leg portions are provided on the bottom surface of the bottom member made of a synthetic resin material, the bottom member may be rattled when the bottom member is installed due to distortion during molding of the bottom member or deformation after molding. Even in this case, it will be possible to absorb it and install it without rattling.

  As a result, according to the problem solving means of the present invention, the cloth storage unit body and the synthetic resin bottom member are firmly connected and integrated, and the portable pouch bottom for storing beverage containers and the like is long-lasting by the resin member. It is possible to provide a portable pouch for storing beverage containers and the like that are durable enough to withstand use.

It is sectional drawing of the principal part which shows the structure of the convex surface part for rattle absorption formed in the bottom wall part (convex part belt | band | zone part) of the portable pouch.

  Hereinafter, with reference to attached FIGS. 1-7, the structure and effect | action of a portable pouch for storage, such as a drink container, concerning embodiment of this invention are demonstrated in detail.

  A portable pouch for storing beverage containers or the like (hereinafter simply referred to as a portable pouch) 1 according to this embodiment includes, as its basic constituent parts, a cylindrical storage body 2 extending vertically and made of a cloth member, It is comprised from the dish-shaped bottom member 3 which consists of a synthetic resin material provided in the lower end part 2b side of the accommodating part main body 2. As shown in FIG.

  For example, as shown in FIG. 1, the storage unit main body 2 is provided with a fastener 30 that is located on the front side and extends from the opening 30 a portion on the upper end side to the opening stop portion 30 b portion on the lower end side. Is opened by lowering the slider 30c from the upper side to the lower side, and conversely, it is closed by pulling it from the lower side to the upper side, and is used for beverages such as drink bottles with the fastener 3 opened. A container 4 is placed and is stored in a portable manner with the fastener 3 closed.

  As shown in FIG. 2, for example, the cylindrical portion of the storage unit body 2 has a triple structure of a front cloth (surface) 21, an intermediate member 22, and an inner cloth (lining) 23, and on the upper end 2a side. Further, a synthetic resin sewing tape 6 such as a polypropylene tape with both side strips folded back in an inverted U shape is used, and a front cloth 21 and an intermediate member 22 are provided between the inner and outer side pieces 6a and 6b of the sewing tape 6. The end portions of the inner cloth 23 are sandwiched and sewn together to form a bag.

  The front cloth 21 and the inner cloth 23 are made of, for example, water-repellent polyester fiber and have high water resistance, while the middle member 22 is formed by, for example, a slightly thick urethane pad having elasticity and stored. While maintaining the rigidity (shape) of the main part 2, the shock to the stored beverage container 4 is absorbed and relaxed.

  And the strap 5 of the length which can be shouldered is attached to the right and left of the upper end 2a side part of the storage part main body 2 of the same structure via the length long member 5a, 5b. The strap 5 is formed of a sewing tape (ribbon tape) made of, for example, a mixed fiber of polypropylene and polyester.

  By the way, the dish-shaped bottom member 3 is formed of a synthetic resin material having high strength (hardness) such as polypropylene, for example, and as shown in FIGS. It has a bottom wall 31 and a side wall 32 corresponding to the diameter.

  In the case of this embodiment, the predetermined upper and lower width portion W1 corresponding to the lower portion of the storage body 2 of the side wall 32 has a lower portion 32b whose thickness (wall thickness) is lower than that. Further, by forming it sufficiently thinner than the bottom wall 31 portion, a thin-walled portion (sewable structure portion) 32a through which a sewing needle of an industrial sewing machine passes can be formed, and the thin-walled portion 32a portion that is the sewable structure portion As described above, it is sewn to the lower portion side predetermined height position portion of the storage body 2 via the synthetic resin sewing tape 7.

  The sewn portion between the side wall 32 of the bottom member 3 and the lower side portion of the storage unit main body 2 has a structure as shown in the cross-sectional view of FIG.

  That is, the upper and lower predetermined width W1 portion of the side wall 32 of the bottom member 3 is thinned considerably thinner than the lower portion 32b and the bottom wall 31 portion by shaving the inner peripheral surface side to a predetermined thickness. It is formed in the portion 32a, and the thin portion 32a has a sewing tape (ribbon-like tape) 7 made of synthetic resin such as polypropylene folded in a U shape in both the inner and outer directions at the center in the width direction. The inner and outer side pieces 7a and 7b, which are arranged so as to cover the upper end and both inner and outer surfaces of the thin portion 32a and are folded back at the lower end side first stitching portion 11 portion, are respectively sewn to the thin portion 32a portion. It is integrated by.

  In this case, the synthetic resin sewing tape 7 has a relatively large thickness and a relatively high rigidity. When the synthetic tape 7 is firmly integrated with the thin-walled portion 32a, the thin-walled tape 7 is formed. The step inside the portion 32 a (step due to cutting) is eliminated, and a contact surface with the outer peripheral surface of the storage portion main body 2 that is flush with the inside of the side wall 32 is formed.

  On the other hand, as described above, the storage unit main body 2 is composed of a triple structure of the front cloth 21, the middle member (urethane pad) 22, and the inner cloth 23, and the lower end portion 2 b portion is slightly of the inner cloth 23. After the front end 23c of the long lower end 23b is folded back to the outer peripheral surface of the lower end 21b of the front cloth 21 in a J shape, the middle member 22 together with the front cloth 21 is sewn together by the second stitching section 12. Closed up.

  Then, the lower end 2b side in the same state is fitted inside the bottom member 3 until it comes into contact with the upper surface of the thick portion 31c portion of the predetermined width W3 on the outer peripheral end side of the upper surface 31a of the bottom wall 31 as shown in FIG. The outer peripheral surface of the side wall portion is brought into close contact with the entire inner peripheral surface of the side wall 32 of the bottom member 3, and the third stitching portion 13 portion on the upper end side of the thin portion 32a of the side wall 32 of the bottom member 3 in the same close state. The sewing tape 7 is sewn together through the thin-walled portion 32a to which the sewing tape 7 is sewn.

  In the case of such a configuration, the bottom member 3 is made of a synthetic resin material having high strength such as polypropylene as a whole, unlike the case where the synthetic resin material is simply molded with respect to the conventional cloth bottom member. Therefore, the strength and durability are sufficiently high.

  In addition, the connection part corresponding to the storage part body 2 made of polyester or the like of the bottom member 3 is formed in a sewable structure part through which a sewing needle of an industrial sewing machine passes, for example. It is possible to easily sew and integrate the storage unit main body 2 through the same part.

As a result, the cloth storage unit main body 2 and the synthetic resin bottom member 3 are firmly connected and integrated, and the bottom of the portable pouch 1 for storing the beverage container 4 and the like is durable to withstand long-term use. Moreover, in the structure part that can be sewn, the thickness of the predetermined width W1 on the upper end side of the side wall 32 to be sewn with the storage body 2 is made thinner than other parts such as the lower part 32b of the side wall 32 and the bottom wall 31. It is formed by the thin portion 32a.

  When forming a stitched portion to be sewn to the storage portion main body 2 of the bottom member 3 in a sewable structure portion through which such a sewing needle passes, the material of the stitched portion corresponding to the storage portion main body 2 is partially made of hardness. It can be considered to be low, or pores corresponding to perforations are formed in advance, but in any case, the processing becomes complicated and the cost increases.

  However, as described above, when a structure in which the thickness of the upper end side opening upper and lower side predetermined width W1 portion of the side wall 32 of the bottom member 3 is made thinner than the thickness of the other portions as the sewn structure portion, Molding is easy, no special processing is required, and a structure that can be sewn at low cost can be obtained.

  In addition, in the case of the above-described configuration, the lower end 2b side of the storage portion main body 2 is extended until it comes into contact with the upper surface of the thick portion 31c portion of the predetermined width W3 on the outer peripheral end side of the upper surface 31a of the bottom wall 31 as described above. Are fitted inside the bottom member 3, and the outer peripheral surface of the side wall portion is brought into close contact with the entire inner peripheral surface of the side wall 32 of the bottom member 3. The three stitching portions 13 are sewn together through the thin-walled portion 32a so as to be sewn together.

  In this way, fraying and the like are less likely to occur compared to the case where the bottom portion 3 is sewn to the side wall 32 only at the lower end portion of the storage portion main body 2, and a stable sewn state is realized. It becomes possible to protect the stitched portion of the storage unit main body 2 at the side wall 32 portion.

  Moreover, since the cylindrical storage part main body 2 is continuing straight to the bottom 31 part, the drink container 4 can be stored smoothly and can be more effectively protected after storage.

  A first stitching portion 11 for sewing the sewing tape 7 to the lower end of the thin portion 32a, and a third portion for sewing the lower portion of the storage portion main body 2 to the thin portion 32a to which the sewing tape 7 is sewn. For example, the perforation (pitch) in the stitching portion 13 is larger in the former perforation and smaller in the latter perforation, and is softer than the storage portion main body 2 which is soft and easy to fray. A stable stitching state is achieved.

  Moreover, in the 1st stitching | suture part 11 which sews the said sewing tape 7 to the lower end of the thin part 32a, and the 3rd stitching part 13 which sews the accommodating part main body 2 to the thin part 32a by which this sewing tape 7 was sewn. Since each perforation is visible from the outside (see FIG. 1), it is sewn using, for example, a thread having the same color as the fabric of the sewing tape 7.

  Further, as described above, when the sewing tape 7 is used and the sewing tape 7 is sewn to the thin portion 32a and then the storage portion main body 2 is sewn to the thin portion 32a, the sewing tape 7 is stored. Since the connecting portion between the main body 2 and the bottom member 3 is covered, not only the appearance is improved, but also the binding force of the sewing portion is increased, and a more stable connection state can be realized. .

  Further, in the case of this embodiment, the corner wall 33 portion and the bottom wall 31 portion on the rounded surface from the lower portion 32b portion of the side wall 32 to the bottom wall 31 portion are used for preventing deformation after molding and durability by use. In order to ensure the property, the strength needs to be higher than the predetermined width W1 portion (thin wall portion 32a) on the upper end side of the side wall 32, and a sufficient thickness is ensured. In particular, the corner wall 33 portion is easily dragged by, for example, the elongated strap 5 or is subject to an impact at the time of dropping. Therefore, the corner wall 33 portion is formed to be particularly thicker than the other portions to increase the strength and absorb the impact. It is getting bigger.

  Further, the bottom wall 31 of the bottom member 3 is basically flat on the upper surface 31a side, and can only stably support the bottom of the beverage container 5 to be stored. On the other hand, on the lower surface 31b side, for example, first to third three annular ribs 15a to 15c having different diameters are provided concentrically, each being located in a predetermined radius area portion in the center. The outer peripheral end portion on the outer peripheral side in the radial direction is provided with a wide convex band 16 having a predetermined width W2 in the radial direction and extending in a band shape in the peripheral direction, and the convex band having the predetermined width W2 The 16 portions include, for example, first to twelfth predetermined 12 pieces extending in the radial direction (radial direction) at intervals of 30 degrees in the circumferential direction and finally extending to the side wall surface portion of the corner wall 33 on the rounded surface. Depth grooves 17a-17l are provided.

  Further, the convex band 16 portion having the predetermined width W2 provided with the first to twelfth grooves 17a to 17l extending in the radial direction at intervals of 30 degrees in the circumferential direction has an interval of 120 degrees in the circumferential direction, for example. The length of each 60 degrees (for example, between the second groove 17b and the fourth groove 17d, between the sixth groove 17f and the eighth groove 17h, and between the tenth groove 17j and the twelfth groove 17l). First to third arcuate leg portions 14a to 14c that are convex downward are provided (see FIGS. 2 to 4, 6, and 7).

  As described above, when the first to third annular ribs 15a to 15c having different diameters are provided at predetermined intervals in the radial direction on the lower surface 31b of the bottom wall 31, they have the same predetermined height. The first to third annular ribs 15a to 15c protect the flat lower surface portion of the bottom wall 31, and the entire lower surface 31b portion is hardly damaged. Further, for example, since only the narrow annular ribs 15a to 15c are damaged even if they hit something, the attached scratches are hardly noticeable.

  Further, the convex band 16 portion of the predetermined width W2 provided with the first to twelfth grooves 17a to 17l extending in the radial direction at intervals of 30 degrees in the circumferential direction is also the same as the annular ribs 15a to 15c. However, as described above, the convex band 16 portion extends to the vertical wall surface of the corner wall 33 on the rounded surface to make the corner wall 33 portion thick. In this case, the predetermined width W3 portion 31c at the outer peripheral end portion on the upper surface side of the bottom wall 31 is also formed thicker than the inner side, thereby further improving the strength of the corner wall 33 portion.

  Further, as described above, the convex band 16 portion having the predetermined width W2 provided with the first to twelfth grooves 17a to 17l extending in the radial direction at intervals of 30 degrees in the same circumferential direction is 120 in the circumferential direction. 60 degrees (for example, between the second groove 17b and the fourth groove 17d, between the sixth groove 17f and the eighth groove 17h, and between the tenth groove 17j and the twelfth groove 17l). The first to third arc-shaped (band-shaped) leg portions 14a to 14c that are convex downward are provided.

  These first to third arc-shaped legs 14a to 14c are, for example, as shown in FIGS. 6 and 7, arc-shaped in the circumferential direction (see FIG. 6), and mountain-shaped in cross section in the radial direction (see FIG. 7). The height of the peak portion is the highest at the center position between the circumferential ends. On the other hand, in the second and fourth grooves 17b and 17d, the sixth and eighth grooves 17f and 17h, and the tenth and twelfth grooves 17j and 17l on both ends in the circumferential direction, It is continuous with the side wall.

  According to such a configuration, even if, for example, deformation of the shape of the bottom member 3 occurs due to molding, the circumferential direction is spaced 120 degrees apart so as not to cause actual rattling at the time of installation. The first to third arc-shaped leg portions 14a to 14c that are convex to the side can be stably supported at the tops of the three central portions without rattling.

  The present invention is not limited to that described in the above embodiment, and it goes without saying that the design can be changed as appropriate without departing from the gist of the invention.

  For example, in the above-described configuration, the whole upper end side predetermined vertical width W1 of the side wall 32 of the bottom member 3 is formed in the thin portion 32a so as to realize a sewable structure. This can also be realized by thinning only the portion through which the groove passes.

  Moreover, the said 1st-3rd circular-arc-shaped leg part 14a-14c which protruded below is comprised so that the height of a peak part may become the highest in the center part position between the circumferential direction both ends. However, even if the height is substantially the same between both ends in the circumferential direction, substantially the same backlash absorbing action can be realized.

  For example, as shown in FIG. 4, dowels 18 necessary for alignment at the time of sewing can be provided at predetermined positions of the side wall portion 32 of the bottom member 3.

  Various modifications can be made to the other parts.
