[Problems to be solved by the invention]
However, in the conventional configuration, the reinforcing adhesive member is provided on the inner surface of the bag body, and the release paper is temporarily attached. Therefore, when the article is put into the bag, the article contacts the release paper. The release paper was peeled off by contact, and the adhesive force of the adhesive member was lowered, and there were some that could not seal the bag satisfactorily.
[0005]
Moreover, when the adhesive force of the reinforcing adhesive member is strong, it is difficult to open the article when the article is taken out, and it is necessary to cut the bag with a blade or the like. Furthermore, when the article is taken in and out, the adhesive of the reinforcing adhesive member may adhere to the article and the article may become dirty.
[0006]
In particular, when the handbag is a cold bag for storing fresh food such as agricultural products and marine products, refrigerated or frozen products, it is important that a reliable sealing state is obtained together with further reinforcement of the handle portion of the handbag. . In addition, when the cold insulation bag is composed of a laminated bag body having a surface with an embossed metal deposition surface, it is difficult to print on the surface, and it is effective for advertising and product display. Display is not possible, and the design is lacking.
[0007]
The present invention solves the above-mentioned conventional problems, and prevents the article from coming into contact with the binder when the article is put in and out of the bag, thereby preventing a decrease in the adhesive force or adhesive strength of the binder. Reinforcing sheets for handbags that can be applied to cold storage bags such as perishable foods, refrigerated products, and frozen products that can prevent contamination of articles, can be surely sealed, and can be easily opened An object is to provide a material, a handbag using the same, and a method for reinforcing the handbag.
[0008]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention provides a reinforcing sheet material used for a handbag having an opening at the upper end of the bag body and a pair of opposite handle holes for handbags on each side surface of the bag body. Because
The reinforcing sheet material is composed of at least a sheet-like base material and a binder layer to which the sheet-like base material is attached,
The sheet-like base material is folded and pasted at the opening from the outer surface of each of the side surfaces, and a sealing portion that seals at least a part of the opening at the top of the bag body from the outside, and is continuous to the sealing portion. A pair of peripheral reinforcing portions provided in accordance with the peripheral shape of each handle hole for the hand-holding, and a pair of hand-holding holes having a cut line corresponding to the peripheral shape of the peripheral reinforcing portion. It is a reinforcing sheet material for handbags having a forming portion.
[0009]
Thereby, for example, the reinforcement sheet material is attached to the outer surface of one side surface portion of the bag body so that the hand hole forming portion of the reinforcement sheet material matches the handle hole of the bag body, and the reinforcement is attached. If the hand hole formation part is cut off from the sheet material cutting line, the hand hole of the reinforcing sheet material is used as the handle hole of the bag body while the peripheral edge portion of the handle hole of the bag body is reinforced by the peripheral edge reinforcing portion of the reinforcing sheet material on the outer surface. It can be penetrated.
[0010]
Further, the reinforcing sheet material is folded back from the outer surface of the one side surface portion at the opening of the bag body, and the other hand hole forming portion of the reinforcing sheet material is formed on the outer surface of the other side surface portion of the bag body. If it sticks so that it may correspond to the other handle hole of a body, at least one part of the opening part of a bag body upper part can be sealed from the outer side of a bag body.
[0011]
Furthermore, if the hand hole forming part is cut out from the cut line of the reinforcing sheet material attached to the outer surface of the other side surface part, the peripheral edge part of the reinforcing sheet material on the outer surface of the peripheral part of the other handle hole of the bag body The other hand hole of the reinforcing sheet material can be passed through the other handle hole of the bag body while being reinforced.
[0012]
Therefore, the reinforcing sheet material of the present invention is in contact with the reinforcing sheet material of the present invention when the article is put in and out of the bag as compared with the reinforcing adhesive member described in the conventional document 1. The structure can be eliminated, and a decrease in the adhesive force or adhesive force of the binder attached to the reinforcing sheet material can be prevented, and the article can be prevented from being soiled. Further, even if the load of the stored article acts in the direction of opening the bag, unlike the conventional inner surface-attached type bag described in Document 1, the force is difficult to act on the structure, so it is reliable. A sealed state is obtained.
[0013]
Further, the reinforcing sheet material of the present invention is configured to be folded and pasted at the opening from the outer surface of each side surface of the bag body, and to seal at least a part of the opening of the bag body from the outside, Furthermore, since the peripheral edge reinforcing portion of the reinforcing sheet material is adhered to the outer peripheral surface of the peripheral edge portion of the handle hole of the bag body,
Even if the load of the article put into the handbag acts on the peripheral edge of the handle hole of the handbag, especially the upper edge of the handle hole and tears the upper edge, the force is applied to the peripheral edge of the reinforcing sheet material. It can be received at the reinforcement.
[0014]
Further, since the handbag is reinforced by the handbag reinforcing material as described above, it is possible to suppress the deformation of the handbag due to the unevenness or weight of the contents during handbag transportation.
[0015]
In addition, as described above, the load of the article put into the handbag acts in the direction in which the side portions of the bag body are separated from each other. Therefore, the upper end side of the handle hole alone at the peripheral edge of each handle hole of the handbag. Although it is likely to receive tearing force at the edge portion, the reinforcing sheet material of the present invention is folded and pasted from the outer surface of each side surface portion of the bag body at the opening as described above. It becomes possible to receive the tearing force on the entire side surfaces of the body.
[0016]
Furthermore, since the thing of the conventional literature 1 is affixed on the inner surface of each said side part of a bag body, it acts in the direction which separates each said side part of the said bag body from each other, and it is easy to separate and open. However, as described above, the reinforcing sheet material of the present invention is folded and pasted from the outer surface of each side surface portion of the bag body at the opening portion, so that the opening portion of the bag body is reliably sealed. .
[0017]
Therefore, since it is possible to suppress the influence due to the transition of air or water vapor from the outside of the bag, especially in the case of a cold insulation bag of a laminated sheet in which a metal vapor deposition layer is formed on this using a thermoplastic resin foam sheet, The cooling effect can be sufficiently improved without impairing the cooling effect.
[0018]
Furthermore, since the reinforcing sheet material of the present invention has a structure in which the binder layer is covered with a release sheet and adhered to the outer surface of the bag body, the adhesive strength / adhesive strength of the binder is higher than that of the conventional literature 1. Can be held for a long time.
[0019]

FIG. 3 is a front view of a handbag showing a state in which the reinforcing sheet material is partially attached to a cold bag for carrying, and FIG. 4 is an enlarged cross-sectional view of a main part of the handbag showing a state in which the reinforcing sheet material is further folded and attached. It is.
[0020]
1 to 3, reference numeral 1 denotes a reinforcing sheet material according to an embodiment of the present invention. As shown in FIGS. 3 and 4, the reinforcing sheet material 1 has an opening 202 at the upper end portion 201 of the bag body 2, and faces the side portions 204 and 205 of the upper portion 203 of the bag body 2. Used for handbags having a pair of handle holes 206, 207 for handbags. In particular, the handbag according to this embodiment is a cold bag, and is formed of a heat insulating sheet. That is, as shown in FIG. 4, thermoplastic resin foam sheets 210 and 211 are placed on metal vapor-deposited layers 208 and 209 obtained by vapor-depositing metal on one side of a synthetic resin film layer via a thermoplastic resin film layer (not shown). The laminated sheet 212 is heat-fused.
[0021]
As shown in FIG. 2, the reinforcing sheet material 1 is composed of a sheet-like base material 101, a binder layer 102 to which the sheet-like base material 101 is attached, and a release sheet 103 disposed on the back surface of the binder layer 102. Yes.
[0022]
As shown in FIGS. 1 and 2, the reinforcing sheet material 1 has a dotted line-like notch 104 at a center position 105 where the sheet is divided into two, and the release sheet 103 is divided into two at substantially the same center position 106. The release sheets 103a and 103b are attached to the binder layer 102.
[0023]
Further, as shown in FIGS. 3 and 4, the reinforcing sheet material 1 is attached by folding back from the outer surface of each side surface portion 204, 205 of the bag body 2 at the opening 202, and from the outside to the upper portion of the bag body 2. A pair of sealing portions 107a and 107b for sealing at least a part of the opening 202 and a pair of the sealing portions 107a and 107b provided in accordance with the peripheral shapes of the handle holes 206 and 207 for carrying Peripheral reinforcement portions 108a and 108b and a pair of hand hole forming portions 110a and 110b having cut-out lines 109a and 109b corresponding to the peripheral shapes of the peripheral reinforcement portions 108a and 108b are formed. Has been. In FIGS. 3 and 4, 111a is a hand hole formed by cutting the hand hole forming portion 110a along the cut line 109a of one peripheral reinforcing portion 108a, and 111b is a cut portion of the other peripheral reinforcing portion 108b. This is a hand hole formed by cutting the hand hole forming portion 110b along the line 109b.
[0024]
In addition, 112 is a 2nd folding | turning part provided in the peripheral reinforcement part 108b of the sheet-like base material 101. FIG. As shown in FIG. 4, the second folded portion 112 protrudes into a hand hole 111b formed by being cut along the cut line 109b. Therefore, the second folded portion 112 is connected to the bag body 2 by the folded line 112a. It can be folded back in the direction of the handle hole 207, can be folded back to the other peripheral reinforcing portion 108a through both the handle holes 207, 206, and pasted on the peripheral peripheral reinforcing portion 108a. The second folded portion 112 is also formed with a dotted cut 113 along the folded line 112a of the peripheral reinforcing portion 108b of the sheet-like base material 101.
[0025]
Therefore, when this reinforcing sheet material 1 is used for a cold bag for carrying, for example, the release sheet 103a is peeled off from the reinforcing sheet material 1, and as shown in FIG. 3, the carrying hole forming portion 110a of the reinforcing sheet material 1 is removed. Is attached to the outer surface of the side surface portion 204 of the bag body 2 so as to come to the position of the handle hole 206 of the bag body 2 of the cold insulation bag. Next, the hand hole formation part 110a is cut along the cut line 109a to form a hand hole 111a penetrating the handle hole 206 of the bag body 2. Subsequently, as shown in FIG. 4, the opening portion of the bag body 2 is peeled off the open surface of the reinforcing sheet material 1 with the release sheet 103 b attached as shown in FIG. 3 while the release sheet 103 b is peeled off. Folded at the opening 202 of the bag body 2 so that the dotted notch 104 of the reinforcing sheet material 1 comes to 202, and further on the outer surface of the other side surface portion 203 of the bag body 2, the other hand hole of the reinforcing sheet material 1 Affixing is performed so that the forming portion 110b is positioned at the other handle hole 207 of the bag body 2. Then, the hand hole forming part 110b is cut along the cut line 109b to form the hand hole 111b, and the second folded part 112 that appears after cutting is folded back along the line 112a toward the handle hole 207 of the bag body 2. Through the two grip holes 207 and 206, the second peripheral reinforcing portion 108a is again folded and pasted on the peripheral reinforcing portion 108a.
[0026]
Since the reinforcing sheet material 1 of the present embodiment can be applied to a cold-holding bag for carrying in this manner, at least a part of the opening 202 at the top of the bag body 2 is sealed from the outside of the bag body 2. Further, since the peripheral reinforcing portions 108a and 108b of the reinforcing sheet material 1 are adhered to the peripheral portions of the grip holes 206 and 207 of the bag body 2 on the outer surface, the load of the article put into the handbag is loaded. Even if a force that acts on the peripheral edge portions of the handle holes 206 and 207, particularly the upper edge portion 206a of the handle hole 206 and tears the upper edge portion is generated, the force is applied to the peripheral reinforcing portion 108a of the reinforcing sheet material 1. Can be accepted. Similarly, the upper end side edge of the handle hole 207 can be received by the peripheral reinforcing portion 108b of the reinforcing sheet material 1.
[0027]
Moreover, since the load of the article put into the handbag acts in a direction to separate the side portions 204 and 205 of the bag body 2 from each other, the handle hole 206 alone is provided at the peripheral portion of each handle hole 206 and 207 of the handbag. However, the reinforcing sheet material 1 is folded and pasted from the outside of the side portions 204 and 205 of the bag body 2 at the opening 202. Therefore, the tear force can be received by the entire side surfaces 204 and 205 of the bag body 2 and the opening 202 of the bag body 2 can be reliably sealed.
[0028]
Further, since the second folded portion 112 is formed in the reinforcing sheet material 1 in particular, it is folded in the direction of the handle hole 207 of the bag body 2 along the folded line 112a, and through both the handle holes 207 and 206, Since it can be folded back to the other peripheral reinforcing portion 108a and pasted on the peripheral reinforcing portion 108a again, the side portions 204, 205 of the bag body 2 are combined with the folding at the opening 202 of the bag body 2. Since the tight mating surfaces are formed, the grip holes 206 and 207 are further reinforced, and the sealing of the opening 202 of the bag body 2 is further ensured.
[0029]
In addition, since the reinforcing sheet material 1 has a dotted line-like cut 104 in the opening 202 of the bag body 2 after sealing, it can be easily opened by breaking the cut 104. Moreover, since the 2nd folding | turning part 112 sealed through the handle holes 207 and 206 can be open | released by breaking the dotted-line notch 113, it can open easily.
[0030]
By the way, this reinforcement sheet material is not limited to said embodiment. As the sheet-like substrate, for example, a synthetic resin film, a synthetic resin fiber sheet, pulp paper, synthetic paper, synthetic resin processed paper, or the like can be used.
[0031]
Since such a sheet-like substrate can be printed on its surface, for example, it is possible to add information such as display of the provider and contents of articles such as agricultural products and fishery products, and designs such as symbols and characters. And can be rich in design. In particular, in order to ensure heat insulation, when the sheet-like base material is composed of a heat insulating sheet using a thermoplastic resin foam sheet as a base material sheet, the thermoplastic resin foam sheet is used as a base material sheet, and the metal vapor deposition layer is a surface. In addition to these, if it is a handbag bag, such as when it is configured with an uneven surface such as embossing the surface of a metal vapor deposition layer etc., in addition to these, this handbag bag will inhibit the heat insulation properties It is possible to give designability without any problems.
Moreover, if it is such a sheet-like base material, since the tolerance with respect to a water | moisture content will improve, the peeling resistance from a bag main body can be improved.
In this respect, it is particularly preferable when the bag is a cold bag.
[0032]
As the dotted line-like cuts, it is only necessary to be able to cut the reinforcing sheet material. For example, a combination of cuts formed in dots or lines such as perforations and dot-dash lines can be used.
[0033]
As the binder that can be used in the present invention, known binders such as adhesives such as polyvinyl alcohol, dextrin and starch, and acrylic, rubber and silicone adhesives can be used.
[0034]
Further, the reinforcing sheet material is provided with a release sheet that is divided into two parts in the binder layer, but there is also a configuration in which the release sheet that is not divided or the release sheet is not provided in all or part of the reinforcing sheet material. Can be adopted.
[0035]
The release sheet is not particularly limited as long as it has releasability from the binder layer. For example, a release sheet using a silicon compound, a fluorine compound, or the like is applied to a plastic sheet, paper, paper laminated with a plastic film, or the like. Can be used.
[0036]
The present reinforcing sheet material can be provided as a single component of the reinforcing sheet material alone, but can also be provided as a handbag set comprising a combination of the reinforcing sheet material and the handbag of the present invention.
[0037]
Further, instead of an independent reinforcing sheet material, a reinforcing sheet material provided with a hand hole penetrating the handle hole of the bag body is already attached to the outer surface of one side surface portion of the bag body. It can also be provided as a handbag having a release paper attached to the back of the remaining open surface.
[0038]
For example, on the outer surface of one side of the bag body, the reinforcing sheet material is attached so that the handbag hole matches the handle hole for the handbag of the bag body, and release paper is attached to the back surface of the remaining open surface A handbag having the reinforcing sheet material. In such a case, an article is put through the opening of the bag body, and then the release sheet of the reinforcing sheet material is peeled off, the reinforcing sheet material is folded back at the opening of the bag body, and is attached to the other side surface portion of the bag body. And sealing at least a part of the opening at the top of the bag body from the outside, and cutting the handbag hole forming portion of the reinforcing sheet material before or after sealing the opening at the top of the bag body If the hand hole is formed by cutting along the line, the handle hole of the hand bag can be well reinforced. As a case of cutting before opening the opening at the top of the bag body, for example, when peeling the release sheet of the reinforcing sheet material, along the cut line while attaching a hand-hole forming part to the release sheet A cutting method can be exemplified. In short, in the present invention, the cutting of the handbag hole forming portion of the reinforcing sheet material may be performed before or after sealing the opening of the bag.
[0039]
The reinforcing sheet material of the present invention can be applied as long as it is a handbag, and the material or structure thereof is not limited, such as paper, a synthetic resin sheet, a heat insulating sheet, etc., but a handbag made of a heat insulating sheet, particularly a cold bag is preferable. Can be used.
[0040]
As the heat insulating sheet, for example, a thermoplastic resin foam sheet or a thermoplastic resin foam sheet in which a film is laminated on the surface can be used.
As the thermoplastic resin foam sheet, it is preferable to use at least one selected from the group of thermoplastic resins such as polyethylene, polystyrene, high impact polystyrene, or polypropylene molded into a foam sheet.
As a film laminated | stacked on a thermoplastic resin foam sheet, the film etc. in which the metal vapor deposition layer was formed in the transparent film thru | or a transparent film can be used.
As the transparent film, it is preferable to use at least one selected from the group of synthetic resins such as polyethylene terephthalate, polybutylene terephthalate, polyamide, polycarbonate, or high heat-resistant polypropylene formed into a film.
[0041]
It is preferable to use at least one selected from the group of aluminum, chromium, nickel or copper for the metal vapor deposition layer formed on the transparent film.
The temperature change inside the handbag can be reduced by forming the handbag from the heat insulating sheet.
[0042]
Moreover, when the thing which laminated | stacked the film in which the metal vapor deposition layer was formed on the surface of a thermoplastic resin foam sheet is used as a heat insulation sheet, since heat radiation from the outside or a light ray can be interrupted | blocked by reflection, heat insulation improves.
[0043]
Thus, although the handbag of the heat insulating sheet is excellent in heat insulating properties, it is preferable to retain the structure as much as possible in order to ensure this heat insulating property, but in this respect, the reinforcing sheet material of the present invention is pasted on the hand bag. If worn, the peripheral edge of the handle hole of the bag body is remarkably reinforced while maintaining the heat insulation inherent in the bag, even if the bag is a handbag of a heat insulating sheet having a peripheral edge of a fragile handle hole.
[0044]
