Description

  The present invention relates to a sealed handbag having a structure in which a bag such as a shopping bag is airtight.

For example, Patent Document 1 discloses a conventional technique in which an opening of a bag is closed. The general configuration is that a sealing tape for closing the opening is attached to the outer surface of the front wall or rear wall near the upper edge of the bag so that the upper end protrudes from the upper edge of the bag, and peeled off from the protruding portion of the sealing tape It is made by attaching paper.
Japanese Utility Model Publication No. 62-203835

The bag closed using the conventional sealing tape for closing the opening is difficult to remove the sealing tape and reuse the bag. Further, when using a bridle, it is not suitable when sealing is required because it is pulled out through a slit provided in the front and rear walls.
An object of the present invention is to provide a hermetic handbag which can easily open and close the opening repeatedly and has a sealing property with the opening closed.

  The means of the present invention is a handbag having front and rear walls made of a non-breathable sheet, both side walls folded inside, and a bottom, wherein the upper edges of the both side walls are formed slightly lower than the upper edges of the front and rear walls. The upper edge portion of the front and rear walls is provided with a linear fastener that can be in close contact with the entire width of the front and rear walls (Claim 1).

  In this means, the bag is made of a non-breathable sheet, and the upper edge portions of the front and rear walls can be opened and closed with a fastener over the entire width thereof, so that the bag can be sealed and closed by closing. Since it can be repeated, there is no problem in reuse. As the non-breathable sheet, a sheet made of polyethylene, polypropylene, vinyl chloride, or a resin-coated cloth can be used.

  The non-breathable sheet is preferably made of polypropylene (Claim 2). In this configuration, no toxic gas is generated even if the bag is incinerated when it is disposed of, and the generation of environmental pollutant gas is small.

  The handbag may have a pocket on the inside (Claim 3). In this configuration, a cold material or a low-temperature material such as dry ice to keep a low temperature according to the application at the time of use, and conversely, a warm material or a heat-generating material for keeping a warm temperature is put in a pocket. And the refrigeration effect or heat retention effect of the bag contents can be obtained. In addition, when used as a bag for storing gifts such as clothing, a fragrance can be put in the pocket, which has the effect of being appreciated by the recipient and enhancing the gift.

  It is preferable that the front and rear walls each have a handle (claim 4). In this configuration, it can be used as an ordinary shopping bag with a sealed opening and closing port. It is preferable that the upper edge portion of the front and rear walls is folded inward, and a bridle is attached to the folded portion (Claim 5). In this configuration, it is possible to attach a sturdy holder.

The device according to the first aspect of the present invention has the effect of being able to be repeatedly opened and closed while being capable of being sealed.
The invention described in claim 2 has an effect that the generation of environmental pollutant gas is small even if the bag is incinerated when disposed of.
The invention according to claim 3 exhibits a refrigeration effect by placing a cold material or a low-temperature material in the pocket, and exhibits a heat retention effect by placing a warm material or a heating material in the pocket. In addition, by using a fragrance in the pocket when used as a bag for storing gifts such as clothing, the gift recipient is pleased and the gift is enhanced.
The invention according to claim 4 has an effect that it can be used as an ordinary shopping bag with a sealed opening and closing port.
The device according to the fifth aspect of the present invention has an effect that a sturdy holder can be attached and a relatively heavy object can be used.

  An embodiment of the present invention will be described with reference to FIGS. This handbag 1 uses a polypropylene sheet as an air-impermeable sheet, and forms a rectangular parallelepiped container-like bag opened upward as shown in FIG. 1, that is, a continuous rectangular front and rear walls 2, 3. The side walls 4, 5 and the bottom wall 6 are provided, the side walls 4, 5 are folded in two along the vertical folding line 7, and the upper end edges of the side walls are set to the upper end edges 2a, 3a of the front and rear walls. About 1 cm lower. This is for attaching the linear fastener 8 to the front and rear wall upper edge 2a, 3a, and corresponds to the width dimension of the linear fastener 8 to be used. The linear fastener 8 is a well-known one, and is formed of a flexible synthetic resin. One of the narrow belts forming a pair has a linear protrusion, and the other corresponds to the protrusion. It has a linear recessed part which meshes | engages with a shape part elastically and will be in an engagement state. One of the linear fasteners 8 is bonded and fixed to the portion of the front wall upper edge 2a and the other to the portion of the rear wall upper edge 3a by heat welding or the like. The engagement state of the linear fastener 8 is obtained by pressing the convex portions and the concave portions of both narrow belt-shaped portions facing each other, and the release is performed by pulling the narrow belt-shaped portions apart.

  The handbag 1 is provided with a pocket 9 on the inner side, for example, on the inner surface of the rear wall 3. The pocket 9 is large enough to accommodate dry ice for cold insulation or a heat generating material that generates heat when exposed to commercially available air for heat insulation. Further, the handbag 1 is provided with hands 10 and 10 on the front and rear walls 2 and 3, for example. For example, the handle 10 is made by cutting a synthetic fiber knitted string into an appropriate length, inserted into the circular holes 11 formed near the upper edges of the front and rear walls 2 and 2 by two from the outside, and the inside. A knot is formed at the end portion of the, and the retaining portion 12 is formed.

  This handbag 1 has an open state in which the linear fastener 8 shown in FIG. 1 is opened on both sides, and puts an object through the opening, puts dry ice or the like into the pocket 9 as necessary, and closes the linear fastener 8. As shown in FIG. 2, the opening is closed. In the handbag 1 with the fastener 8 closed, the bag is formed of a non-breathable material, the fastener portion is hermetically sealed, and the upper edge 4a is folded in half on each of the side walls 4 and 5. 5a is sandwiched and regulated by the front and rear wall upper edge portions 2a and 3a at positions along the fastener 8 and is almost airtight. Therefore, it is optimal for relatively simple heat insulation or cold insulation of the contents. In addition to keeping warm and cold, for example, it can be used to carry pickled vegetables with a strong smell, dried fish, etc., so that almost no odor leaks to the outside.

  In the above-described embodiment, the handle 12 is an attachment structure in which a narrow belt-like material made of a synthetic resin is thermally welded to the wall surface of the bag without drilling the circular hole 11 so that the air in the bag does not enter and exit. Also good. Further, the upper edge portion of the front and rear walls may be folded back inward to increase the strength, and a relatively strong supporter may be attached to this portion. Further, the bottom may have a configuration in which the bottom wall 6 is omitted and both side walls are folded inward so that the lower end edges of the front and rear walls are welded and joined, and the shape of the bottom is a sealed structure in the present invention. There is no particular limitation as long as there is.

  Since it is a sealed type, it can be used as a shopping bag for storing clothing, food, confectionery, etc., and it can also be used as a packaging bag for gifts.

It is a perspective view which shows one Example of this invention. It is a schematic front center longitudinal cross-sectional view of the Example.
