Description

[Detailed Description of the Invention] The present invention is characterized in that the bottom part is folded inward, the edges excluding the opening are glued in a strip shape, and the four corners of the folded part are glued to the outer layer in a substantially triangular shape. It has a fitting part consisting of a male claw and a female claw that can be opened and closed over the entire length of the opening near the opening, and the handle is provided so as to extend beyond the fitting part to the bag body, and a reinforcing strip is fitted on top of it. The purpose of the synthetic resin carrier bag, which is fixed across two parts, is to prevent the contents from escaping outside the bag when storing liquids such as drinking water or powder or granules. It does not fall over even when placed on a horizontal surface, and the tightening force applied by the handle to the mating part during transportation prevents the mating part from accidentally collapsing even when a considerable amount of weight is stored. To provide a synthetic resin carrying bag with a fitting that does not open and has self-reliance for use as a water supply bag in times of disaster.

Conventional carrier bags have a fitting part consisting of a male claw and a female claw near the opening of the carrier bag, and the edges and bottom of both sides excluding the opening are glued in a band shape, and the fitting part It is made of a synthetic resin sheet or film with a finger insertion part of an arbitrary shape in the hand part above the position, or a belt-shaped handle is used as a fitting part instead of providing a finger insertion part in the hand part. Some were attached using adhesives or hot melt adhesives to prevent them from straddling the surface. However, since the above-mentioned carrier bag has a flat sealed bottom, when the contents are stored and placed on a flat surface, it does not have a wide bottom and is not self-supporting, and is susceptible to pressure caused by falling. However, when the contents are stored in a bag and hung, there is no particular problem if the bag is lightweight, but the weight is large. If this increases, the load may be applied to the finger insertion part or the handle, resulting in deformation of the finger insertion part or the handle, resulting in instability of the hand, damage to the finger insertion part or handle, or damage to the interface between the finger insertion part or the handle and the fitting part. There were drawbacks such as damage and difficulty in opening the fitting part.

The present invention eliminates the drawbacks of the conventional carrier bags mentioned above, and has a fitting device that prevents the fitting part from opening accidentally even when storing a considerable amount of weight, and allows the bag to stand upright stably on a flat surface. This is a synthetic resin carrier bag, and one embodiment of its configuration will be described below with reference to the drawings.

In FIG. 1, 1 is a male claw 8 and a female claw 9 for fitting into the inner surface of a set of two films as shown in FIG.
This is a fitting portion having separate and opposing parts. This fitting part can be easily disassembled by separating the two films of the fitting part left and right or front and back, and also by fitting both ends of the male claw 8 and female claw 9 in advance, and then It is designed so that the whole part can be easily fitted together by pressing the entire claw part with your finger. 2 is a handle, and the reinforcing strip 3 at the bottom end of the handle 2 is the fitting part 1.
The bag body 5 is provided so as to extend beyond the bag body 5. A method of fixing a part of the reinforcing strip 3 of the handle 2 below the fitting part 1 may be by using an adhesive sheet, an adhesive, or an adhesive sheet, or by fixing a part of the reinforcing strip 3 of the handle 2 below the fitting part 1. A suitable adhesive may be applied to the surface, the surface thereof covered with a release paper, and the release paper may be peeled off and attached at the time of use. Reference numeral 4 denotes an adhesive portion, which is usually bonded by heat sealing. Reference numeral 6 denotes an adhesive section in which the outer layer of the bag 5 and the folded section 7, in which the bottom is folded inward, are adhered in a substantially triangular shape, and are usually heat-sealed. 7 is a folding part for providing independence, and when the contents are stored in the bag body 5,
As shown in FIG. 4, it becomes flat according to the weight of the contents, providing a stable bottom surface 10.

Examples of the synthetic resin in the bag 5 of the present invention include polypropylene, high-density polyethylene, low-density polyethylene, polyvinyl chloride, polyester, etc., and these can be used as a single film or sheet, or as various films or sheets of these. Can be used as a laminated film or sheet pasted together. Also,
Crosslinked products, low foam products, and pigmented products of these can also be used. Hand carriers made of these synthetic resins are usually used as they are, but they may be subjected to surface treatments such as printing or embossing as appropriate.

The method of attaching the fitting part 1 to the bag body 5 is as follows.
Fusion may be performed using a high frequency welder, an ultrasonic welder, or a heated metal, or an adhesive, an adhesive, an adhesive tape, etc. may be used, and these may be selected as appropriate. The fitting part 1 is connected to the bag body 5
The entire surface in contact with the bag 5 may be bonded or fused, or a portion of the surface in contact with the bag 5 may be bonded or fused. Further, multiple point bonding, fusion bonding, line bonding, or fusion bonding can be applied, but at least the male claw 8 and female claw 9 must be adhesively fixed.

Further, a reinforcing band is provided on the outer surface of the bag body 5 near the fitting part 1. The material of the reinforcing band is not limited to synthetic resin, and may be any material that is useful for reinforcing the vicinity of the mouth. The reinforcing band can be attached to the bag body 5 by either adhesion or fusing.

In addition, the handle 2 may be of the same quality as the bag 5, or may be of a different type.

As described above, in the present invention, the male claw 8 and the female claw 9 for fitting are provided in the vicinity of the opening of the bag body 5 so as to fit against the inner surface of each film, so that the product can be easily removed. Not only can loading and unloading be carried out efficiently with one touch, but also the stored articles are completely isolated from outside air and dust by fitting the male claw 8 and female claw 9 together. In addition, in order to attach the handle 2 to the fitting part 1 of the carrying bag so as to cross over the fitting part 1 and hang onto the bag body 5, the tensile force applied to the fitting part 1 when the contents are stored and hung is Since it is supported by the handle 2, there is no deformation of the fitting part 1, the supporting force of the fitting part 1 against the load is increased, and a stable holding condition is maintained. Further, the opening and closing operations of the fitting portion 1 can be smoothly performed without causing any hindrance to the opening and closing operations.
Furthermore, the bottom of the bag 5 is folded inward, and the four corners of the folding part 7 are glued to the outer layer of the bag 5 in a substantially triangular shape, so when an item is stored, the folding part 7 is folded inward. It becomes flat, forming a stable and wide bottom surface 10 that can stand upright, and therefore does not fall over even when placed on a horizontal surface.
