Description

  The present invention relates to a horizontal holding handbag and a method for manufacturing a horizontal holding handbag. More specifically, the present invention relates to a structure and a manufacturing method suitable for application to a handbag used for carrying a packaging container used to provide, for example, a lunch box, side dish, cake or sweet.

  Made of polystyrene, polypropylene, pulp, etc., made of polyethylene, etc. as a bag for carrying topless packaging containers filled with lunch boxes, side dishes, cakes, sweets, etc. Handbags, often called plastic bags or convenience store bags, are often used.

  In the case of the combination of the packaging container and the handbag, it is very difficult to keep the horizontal posture by fixing the position of the container accommodated in the bag during carrying.

  As a cause of this, there is a heat-sealing sealing part where the side surfaces are bound to each other at the lower end of the conventional handbag, it is easy to be folded and closed at this heat-sealing sealing part, and the bottom part is bent to be folded. The tendency to do is strong. Since the bottom of the bag tends to be folded and folded in this way, the fitting range between the size of the bag and the size of the container for maintaining the horizontal posture of the packaging container in the bag (in other words, The preferred range of combinations) is limited and narrow. Nonetheless, conventional handbags have a bag width that is defined by the width (length) of the heat-sealing seal at the bottom, and the bag circumference (waist circumference) including the bag (also called gusset). The size is fixed to a specific design value for each bag, and the combination of the size of the bag and the size of the container is often outside the preferred range for maintaining a horizontal posture. And if the combination of the bag and the container is out of the preferred range even a little, the movement of the center of gravity due to walking occurs in the container or external force such as hitting the feet of the carrier from the outside of the bag is applied to the container, Among them, there was a problem that the packaging container easily tilted, and finally the container stood vertically in the bag in such a manner that one side surface of the container was along the heat-sealing sealing line at the bottom of the bag. In addition, the problem of the tilting of the packaging container in this bag is that a plastic bottle or the like is a heavy article with an unstable placement position when placed on the lid (top) of the container contained in the bag. It was further increased by joining.

  In this way, when a heavy bag whose placement position is unstable such as a combination of a handbag and a packaging container that is not within the preferred range or a plastic bottle is further mixed and loaded, the container is inclined in the bag, and the container It is said that the convenience and comfort are high due to inconveniences such as losing the aesthetics of the arrangement, mixing different dishes, spilling liquid contents such as sauce etc. There is no problem.

  In order to solve the above-described problems, the following prior art proposes a mechanism for maintaining a horizontal posture of a container accommodated in a bag.

  Specifically, the plastic bag of Patent Document 1 is provided with horizontal holes at the four corners of the bottom portion when the container is accommodated in the bag, and the four corners of the container when the container is accommodated in the plastic bag. Is fitted and held in the horizontal hole.

  In addition, the plastic bag of Patent Document 2 is provided with cuts, irregularities, and needle holes at the edge of the container when the container is stored in the peripheral surface (side surface), and the container is stored in the plastic bag. When this occurs, the edge of the container is caught by the cut or the like and held.

  However, according to the technique of the above-mentioned patent document 1, the handbag used is lacking in versatility corresponding to the difference in size and shape of the container accommodated therein, and a dedicated handbag is prepared for each size and shape of the container. There is a problem of having to.

  In addition, according to the technique of the above-mentioned Patent Document 2, in order to ensure versatility corresponding to the difference in size of the container accommodated in the handbag, it is necessary to provide a considerable number of cuts that become holes in the handbag. There is a trade-off between securing the tensile strength of the handbag and ensuring versatility corresponding to the size difference of the container, and there is a problem that the tensile strength is lowered when trying to improve versatility. In addition, there is a problem in that the cut that becomes the hole of the handbag may not function at all depending on the shape of the container, such as the absence of an edge.

  Further, in any of the techniques of Patent Document 1 and Patent Document 2, since the waist of the bag needs to exceed the waist of the container, a container having a large planar area such as a large lunch box is accommodated. In some cases, it is necessary to use a large-sized bag even if only one item is accommodated, leading to a waste of bag material resources and costs.

  Therefore, the present invention can improve the convenience and comfort by maintaining the horizontal posture when carrying the contents, and can ensure the tensile strength as a hand-carrying tool. It is an object of the present invention to provide a handbag and a method for manufacturing the handbag that can deal with different sizes and shapes, and can have high versatility that can exhibit the function of maintaining the horizontal posture of the contents regardless of the shape of the container.

  In order to achieve such an object, the horizontal holding handbag according to claim 1 is continuous with the opposed peripheral wall portions and the lower ends of the opposed peripheral wall portions, and is sandwiched between the opposed peripheral wall portions to constitute the bottom portion.

  Therefore, according to this horizontal holding handbag, there is no sealing part at the bottom, and the shape of the bag when the object is accommodated therein is not affected by the dimensions of the sealing part at the bottom. It can be accommodated and packaged in close contact with and adaptable to any shape, and the position of the contents with respect to the handbag when carrying can be fixed to maintain the horizontal posture and to accommodate various sizes and shapes. In addition, since there are no cuts, irregularities, needle holes, etc. on the peripheral surface (side surface), the strength as a handbag is not impaired, and the function of maintaining the horizontal posture of the container is demonstrated regardless of the shape of the container. Is done.

  According to a second aspect of the present invention, there is provided a horizontal holding handbag manufacturing method in which gusset portions are formed at opposite positions in the cross-section perpendicular to the axis of the cylindrical raw material, and perpendicular to the original axial direction of the cylindrical raw material. A circumferential wall sealing portion in a direction to be spaced apart and a grip sealing portion in a direction perpendicular to the axial direction is separated from a portion where the gusset portion is formed, and a mountain fold ridge line of the gusset portion A part including at least a part of the is cut off.

  According to this method for producing a horizontal holding handbag, a handbag having the same effects as the horizontal holding handbag of claim 1 is produced.

  The horizontal holding handbag according to claim 3 includes grip portions 3 and 3 extending laterally from both side ends of the peripheral wall portions 2 and 2 which face each other and are continuous at the lower end, and both sides of the opposed peripheral wall portions 2 and 2. The peripheral wall sealing portions 2a and 2a are formed closer to the opening end side of the peripheral wall portion than the handle portions 3 and 3 at the end portions, and the handle sealing portions 3a and 3a are formed at the side end portions of the grip portion 3. ing.

  Therefore, according to this horizontal holding handbag, there is no sealing part at the bottom, and the shape of the bag when the object is accommodated therein is not affected by the dimensions of the sealing part at the bottom. It can be accommodated and packaged in close contact with and adaptable to any shape, and the position of the contents with respect to the handbag when carrying can be fixed to maintain the horizontal posture and to accommodate various sizes and shapes. In addition, since there are no cuts, irregularities, needle holes, etc. on the peripheral surface (side surface), the strength as a handbag is not impaired, and the function of maintaining the horizontal posture of the container is demonstrated regardless of the shape of the container. Is done.

  According to the horizontal holding handbag and the method of manufacturing the horizontal holding handbag of the present invention, it is possible to realize a stepless adaptable structure without restriction, and to fix the position of the contents with respect to the handbag when carrying, so that the horizontal posture can be maintained. It will be possible to improve convenience and comfort. Moreover, since it can respond to various sizes and shapes, it is possible to improve versatility. In addition, since the peripheral surface (side surface) is not provided with cuts, irregularities, needle holes, or the like, and the strength is not impaired, the strength as a handbag can be ensured. Furthermore, since the horizontal posture maintaining function of the stored item can be exhibited regardless of the shape of the stored item, it is possible to improve versatility also in this respect.

The horizontal holding handbag 10 is connected to the opposed peripheral wall portions 2 and 2 and the lower ends of the opposed peripheral wall portions 2 and 2 and sandwiched between the opposed peripheral wall portions 2 and 2 to form a bottom portion. The gusset portion 1, the peripheral wall portion opening end 4 facing the gusset portion 1, and the lower end portions of the gusset portion 1 and the peripheral wall portion 2 are respectively provided at both ends of the fold line 1 a in the direction X of the gusset portion 1. Of the grip portion 3, the cut-out portions 12, 12 formed across the mountain fold ridge line 1a at both ends in the direction X of the mountain fold ridge line 1a of the gusset portion 1, and the direction of the mountain fold ridge line 1a of the gusset portion 1 The peripheral wall sealing portions 2a and 2a on the peripheral wall opening end 4 side and the handle sealing portions 3a and 3a on the gusset portion 1 side formed on both ends of X with the cutout portion 12 interposed therebetween.

  As shown in FIG. 1, the horizontal holding handbag 10 of the present embodiment includes a peripheral wall portion 2, a gusset portion 1 provided continuously with a lower end of the peripheral wall portion 2, and both lateral ends of the gusset portion 1 (in FIG. 1). And left and right ends) and a handle portion 3 provided continuously. And the end (upper end in FIG. 1) which opposes the gusset part 1 of the surrounding wall part 2 is the surrounding wall part opening end 4. FIG.

  The peripheral wall portions 2 and 2 are configured so as to face each other on the front surface and the back surface in a state where the peripheral wall portion opening end 4 is closed and the handbag 10 is folded as shown in FIG. An integral side peripheral wall as the handbag 10 is formed while facing the opening bag 4 in a state where the opening bag 4 is opened and the handbag 10 is used.

  As shown in FIG. 1, the gusset portion 1 is sandwiched between opposing peripheral wall portions 2 and 2 (front and back surfaces) in a state where the peripheral wall portion opening end 4 is closed and the handbag 10 is folded to form peaks and valleys. As shown in FIG. 2, the bottom of the handbag 10 is formed in a state where the peripheral wall opening end 4 is opened and the handbag 10 is used. In the present embodiment, the gusset portion 1 is composed of one mountain and two valleys between the peripheral wall portions 2 and 2 on both sides of the mountain, but the number of peaks and valleys of the gusset portion 1 is as follows. It is not limited to this.

  The gusset portion 1 and the lower end of the peripheral wall portion 2 are continuous in a direction orthogonal to the direction X of the mountain fold ridge line 1a of the gusset portion 1 sandwiched between the opposing peripheral wall portions 2 and 2 (hereinafter referred to as the gusset ridge line direction X).

  And the accommodation space 5 of the handbag 10 is formed by the bottom part comprised by the gusset part 1, and the side surrounding wall comprised by the surrounding wall parts 2 and 2. As shown in FIG.

  The handle portion 3 is provided on both sides of the gusset portion 1 and the peripheral wall portion 2 in the gusset ridge line direction X and continuously with the lower portions of the gusset portion 1 and the peripheral wall portion 2 in the gusset ridge line direction X. In the handle portion 3, the portion that continues from the lower portion of the peripheral wall portion 2 and the portion that continues from the gusset portion 1 face each other, and a combination of these portions faces each other in one handle portion 3 (front view). , Reverse side).

  Further, the peripheral wall portion 2 includes peripheral wall sealing portions 2a and 2a at the peripheral wall portion opening end 4 side of the gusset portion 1 at both ends in the gusset ridge line direction X, respectively. Furthermore, the handle portion 3 includes handle sealing portions 3a and 3a at the end portions that are not continuous with the gusset portion 1 and the peripheral wall portion 2 (in other words, at both ends in the gusset ridge line direction X). In addition, these sealing parts 2a and 3a are formed by heat-bonding or adhere | attaching the surrounding wall parts 2 and 2 which oppose, for example.

  And since the sealing part by heat sealing | fusion etc. is not formed in the gusset part 1, this invention becomes a structure which does not have a sealing wire (sealing part) in a bottom part.

  Here, in the present embodiment, the handle sealing portion 3a is formed from the peripheral wall sealing portion 2a in the gusset ridge line direction X in a state where the peripheral wall portion opening end 4 is closed and the handbag 10 is folded as shown in FIG. Is also located outside. That is, in the folded state as shown in FIG. 1, the dimension L1 between the peripheral wall sealing parts 2a, 2a on both sides (in other words, the dimension in the gusset ridge line direction X direction of the peripheral wall part 2) is L1. It is formed shorter than the dimension L2 between the stop parts 3a and 3a (in other words, the dimension in the gusset ridge line direction X in which the peripheral wall part 2 and the handle parts 3 and 3 on both sides are combined).

  Note that the overall size of the handbag 10 and the dimensions of the gusset portion 1, the peripheral wall portion 2, and the handle portion 3 are not limited to specific sizes and values, but are intended for use and the shape of the contents. , Size and number are set appropriately.

  The handbag 10 is manufactured using, for example, a polyethylene cylindrical raw material.

  Specifically, as shown in FIG. 7, peaks and valleys are formed with respect to the axial center so that the mountain fold ridge line 1 a is in the axial direction at positions facing each other in the cross section perpendicular to the axis of the cylindrical raw material 11. The gusset portions 1 and 1 to be folded are formed in advance. And the cylindrical raw material 11 is leveled flat in a state where the gusset portions 1 and 1 are folded in opposition to the inside.

  The gusset portions 1, 1 are formed and folded and flattened into a cylindrical raw material 11, and the axial center direction is set to a portion centered on the original axial center position (position 18 in FIG. 7). The peripheral wall sealing portion 2a in the orthogonal direction is formed by thermal fusion at a predetermined interval (interval based on the dimension L1), and the gusset portion 1 is formed at both edge portions separated from the original axial position. A grip sealing portion 3a in a direction orthogonal to the axial direction is formed by thermal fusion at a predetermined interval (interval based on the dimension L2) and a predetermined positional relationship with the peripheral wall sealing portion 2a. And the cylindrical raw material 11 is cut | disconnected in the direction orthogonal to an axial direction by the dimension L2 of an axial direction (cut lines 17 and 17 in FIG. 7). In the example shown in FIG. 7, two handbags 10 are manufactured from the original form 11a cut by the dimension L2.

  Then, a predetermined number of original shapes 11a cut with a dimension L2 in the axial direction are overlapped to perform cutting for forming the grip portion 3. Cut portions (shaded portions indicated by reference numeral 12 in FIG. 7) cut by cutting are folds of the gusset portion 1 at both end portions in the gusset ridge line direction X of the original shape 11a (that is, the axial direction of the cylindrical raw material 11). A range including at least a part of the ridge line 1a is set. And in this embodiment, the surrounding wall sealing formed in the direction orthogonal to an axial direction at the part centering on the original axial center position (18) of the cylindrical raw material 11 folded and made flat. The portion 2a is cut without reaching the gusset portion 1 portion on both edge portions of the cylindrical raw material 11.

  In the present embodiment, the dimension L1 between the peripheral wall sealing parts 2a and 2a is shorter than the dimension L2 between the grip sealing parts 3a and 3a, which is the dimension of the original shape 11a, and therefore, between the peripheral wall sealing parts 2a and 2a. A portion that is not required when the dimension is set to L1 is also cut as a cut-out portion 12.

  By opening the peripheral wall portion open end 4 upward by setting the cutout portion 12 in a range including at least a part of the mountain fold ridgeline 1a of the gusset portion 1 at both ends of the original shape 11a in the gusset ridgeline direction X The gusset portion 1 is easy to expand, the bottom portion of the handbag 10 is easily formed, and the side wall of the handbag 10 is formed by the peripheral wall portion 2 having the peripheral wall sealing portions 2 a, 2 a, and the bottom portion and the peripheral wall portion 2 formed by these gusset portions 1. A storage space 5 for the handbag 10 is formed by the side peripheral wall.

  Further, by setting and cutting the cut portion 12 so as to include a part of the mountain fold ridge line 1a of the gusset portion 1, a loop-shaped handle 3 having the cut portion as a hole portion is formed.

  Finally, the horizontal holding handbag 10 is completed by cutting at the original axial position of the cylindrical raw material 11 (cut line 18 in FIG. 7).

  By manufacturing the handbag 10 as described above using the cylindrical raw material 11, the handbag 10 can be efficiently laid out on the cylindrical raw material 11, and waste of bag material resources and costs is saved. be able to. However, the manufacturing method / manufacturing process of the handbag 10 described above is an example, and the manufacturing method of the horizontal holding handbag of the present invention is not limited to the above.

  Specifically, the above-mentioned horizontal holding handbag 10 is used as shown in FIGS. First, as shown in FIG. 2, the peripheral wall portion opening end 4 is opened upward, and the gusset portion 1 is expanded. Thereby, the accommodation space 5 is formed.

  Then, as shown in FIG. 3, for example, a food container 13 such as a general lunch box is accommodated in the accommodation space 5. At this time, when the horizontal, vertical, and horizontal dimensions of the food container 13 are different as in the example shown in FIG. 3, it is preferable to arrange the container 13 so that the plane major axis direction is perpendicular to the gusset ridge line direction X.

  For example, when a columnar beverage container 14 such as a plastic bottle is further accommodated, the beverage container 14 is placed on the food container 13 as shown in FIG. At this time, it arrange | positions so that the column-axis direction of the container 14 for drinks may become in parallel with the gusset ridgeline direction X. FIG. And when there is only one container 14 for drinks, it arrange | positions so that the pillar axis | shaft of the container 14 for drinks may be located on the mountain fold ridgeline 1a of the gusset part 1. FIG.

  Subsequently, as shown in FIG. 5, the peripheral wall sealing portions 2 a, 2 a of the peripheral wall portion 2 are abutted above the food container 13 and the beverage container 14, and the food container is formed by the upper portion of the peripheral wall portion 2. 13 and the upper part (top surface) of the beverage container 14 are covered.

  Then, as shown in FIG. 6, the size and shape of the bottom surface and the side wall of the handbag 10 are automatically adjusted by the weight of the containers 13 and 14 by lifting both the grip portions 3 and 3 together, and the bottom surface of the handbag 10 ( That is, the gusset portion 1) and the side peripheral wall (that is, the peripheral wall portion 2) are brought into close contact with the bottom and side surfaces of the containers 13, 14, and the containers 13, 14 are securely fixed to maintain the horizontal.

  Further, due to the weight of the contents, triangles 15 and 15 of tension connecting the bottom surface of the handbag 10 (the gusset portion 1) and the handle portion 3 sandwich the containers 13 and 14 (on the front side and the back side in FIG. 6). Opposed. Accordingly, when the column axis direction of the beverage container 14 is arranged so as to be parallel to the gusset ridge line direction X, the heads and the bottoms of the beverage container 14 at both ends in the column axis direction are sandwiched by the tension triangles 15. And fixed (the position of the circle 16 in FIG. 6). Thereby, even if the container 14 for drinks is a column shape, a position is fixed reliably so that it does not roll, and the gravity center position of the stored thing in the handbag 10 is stabilized in the position substantially right under the handle part 3. FIG.

  According to the horizontal holding handbag 10 configured as described above, the peripheral wall 2 is not provided with cuts, irregularities, needle holes, or the like, so that the strength of the handbag is not impaired.

  Further, according to the horizontal holding handbag 10, since there is no sealing wire (sealing portion) at the bottom (ie, the gusset portion 1), a relatively thin rectangular parallelepiped side surface like a lunch box is applied to the sealing wire. Thus, it is possible to prevent the contents from standing upright.

  Moreover, according to the horizontal holding handbag 10, the bottom portion (the gusset portion 1) has no sealing portion, and the shape of the bag when an object is accommodated therein is not affected by the size of the bottom sealing portion. Therefore, it can be accommodated and packaged in close contact with and conforming to the size and shape of the contents, and the position of the contents relative to the handbag when carrying can be fixed and the horizontal posture can be maintained. In particular, the position of the columnar beverage container can be reliably fixed by the tension triangle formed by the bottom surface (the gusset portion 1) and the handle portion 3, and the misalignment and posture of the stored item relative to the handbag when being carried Disturbance can be reliably prevented.

  In addition, although the above-mentioned form is an example of the suitable form of this invention, it is not limited to this, A various deformation | transformation implementation is possible in the range which does not deviate from the summary of this invention. For example, in the above-described embodiment, the horizontal holding handbag 10 is made of polyethylene, but the material of the handbag in the present invention is not limited to this, and is appropriately selected in consideration of the contents, usage scenes, and the like. Specifically, for example, nylon, nonwoven fabric, hemp or cotton may be used. Depending on the material, the peripheral wall sealing portion 2a and the handle sealing portion 3a may be formed by adhesion or by sewing.

  Moreover, the shape and form of the horizontal holding handbag of the present invention are not limited to the specific shapes and forms shown in FIGS. 1 to 7 as the above-described embodiment. As long as it corresponds to the above-mentioned embodiment, if at least the cut-out portion 12 is formed to straddle the mountain fold ridge line 1a in each of both end portions in the direction X of the mountain fold ridge line 1a of the gusset portion 1, other specific Various shapes and forms may be appropriately arranged.

  For example, in the above-described embodiment, the dimension L2 between the handle sealing portions 3a and 3a is formed longer than the dimension L1 between the peripheral wall sealing portions 2a and 2a. The size relationship is not limited to this, and the dimension L1 between the peripheral wall sealing portions 2a, 2a and the handle sealing portions 3a, 3a depending on the intended use and the shape, size, and number of items to be accommodated. The dimension L2 may be the same (FIG. 8 (A); the cutout portion 12 is formed across the mountain fold ridge line 1a at each of both end portions in the direction X of the mountain fold ridge line 1a of the gusset portion 1). The dimension L1 between the peripheral wall sealing parts 2a and 2a may be longer than the dimension L2 between the handle sealing parts 3a and 3a (FIG. 5B). The mountain fold ridge line 1a is straddled across each of the both end portions in the direction X of the mountain fold ridge line 1a. Since the dimension L2 between the sealing parts 3a and 3a is shorter than the dimension L1 between the peripheral wall sealing parts 2a and 2a, the unnecessary part is included when the dimension between the handle sealing parts 3a and 3a is set to L2. Is formed). Further, the shape of the cutout portion 12 may be a rectangle, a triangle, an ellipse, or the like.

  In the above-described embodiment, the peripheral wall sealing portion 2a is cut at the cutout portion 12 so as not to reach the gusset portion 1 portion. The peripheral wall sealing portion 2a may extend (in other words, the peripheral wall sealing portions 2a and 2a may be formed with the cutout portion 12 interposed therebetween).

  Moreover, in the above-mentioned embodiment, although the bottom part is comprised by the gusset part 1, you may make it a form which does not have a gusset part. Specifically, as shown in FIG. 9, grip portions 3, 3 extending laterally from both side ends of the peripheral wall portions 2, 2 facing each other at the lower end, and both sides of the opposed peripheral wall portions 2, 2. The peripheral wall sealing portions 2a and 2a formed on the peripheral wall portion opening end 4 side of the end handle portions 3 and 3 and the side end portions of the handle portion 3 (in other words, on the side opposite to the peripheral wall portion 2). You may make it have the handle sealing parts 3a and 3a which are. In the example shown in FIG. 9, the peripheral wall portions 2 and 2 facing each other are continuous (folded back) at the lower end (that is, the end opposite to the peripheral wall portion opening end 4). Further, in this case, in order to form the handle portion 3, a portion cut out on the upper side (the peripheral wall portion opening end 4 side) and the lower side (the lower end (bottom side) of the peripheral wall portion 2) with the handle portion 3 interposed therebetween. 12 is set. The handle portion 3 in which the handle sealing portion 3a is formed by the cut portions 12 and 12 has a loop shape in which both the upper side and the lower side are cut off and opened. In this case, the lower portions of the opposed peripheral wall portions 2, 2 constitute the bottom portion 1 '. And also in this case, there exists an effect similar to the horizontal holding handbag 10 of the above-mentioned embodiment.

  Further, in the above-described embodiment, all of the gusset portion 1, the peripheral wall portion 2, and the handle portion 3 are configured as a single unit. However, a part of these may be configured separately and attached. Each part may be configured as a separate body and assembled. In this case, each part may be made of different materials.

  In addition, for example, when it is supposed to be used repeatedly a plurality of times, such as an eco bag, a specification may be added in order to further improve usability. For example, a magic tape (registered trademark), a fastener, a snap button, or the like that enhances the prevention of spillage of the contents by joining the edges of the peripheral wall parts 2 facing each other to the edge part of the peripheral wall part 2 near the opening end 4 of the peripheral wall part May be provided. Moreover, you may provide the pocket etc. which can store accessories, such as gum and chocolate, and the net pocket etc. which can store bag confectionery, such as a snack. Further, the handle may be formed of a cylindrical core material in order to improve ease of holding.
