Abstract

PURPOSE:To conduct sewing a fastener on a storage bag through one process by the use of a twin needle sewing machine by conducting sewing of a fastener part only through one process of the sewing operation of the fastener and by omitting the sewing operation of a cloth from the sewing places of fastener ends to the bottom of the bag and the sewing operation of a stay cloth. CONSTITUTION:When respective ends of a fastener 1 to be attached to the top face of a bag from the center of the bag over both left and right side faces are extended long and the joints of the side face (b) or (c) and the bottom face (d) of the bag are sewn together, they are sewn simultaneously.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage bag made of a woven cloth made of cotton, hemp, chemical fiber or the like or a non-woven cloth made of polypropylene, polyester, nylon or the like. Concerning the omitted storage bag.

[0002]

2. Description of the Related Art As a storage bag using a fastener, there are a type that opens from the center of the top surface to the left and right sides of the fastener and a type that opens from the center, and a type that opens the fastener from the front side to the left and right sides of the bag. known. In any of these cases, the fasteners are attached from the middle part of one side of the storage bag to the middle part of the other side, and when attaching the bags, traditionally, sewn cloth from the place where the fastener end is sewn to the bag bottom or back side. After that, the fasteners were sewn, and then the sewn cloth was sewn to each end of the fastener to improve the appearance of the sewn fastener and to reinforce it.

[0003]

As described above, in the conventional storage bag, when the fastener portion is sewn, the cloth is sewn from the place where the fastener end is sewn to the bag bottom portion or the bag back surface, and the fastener is sewn. It is necessary to perform three steps of work, such as attaching and sewn the sewn cloth, and it is necessary to change the direction of the cloth in each process. It was burning.

According to the present invention, the steps and time for sewing the fastener portion can be shortened by omitting the steps of sewing the cloth and sewing the cloth, and the appearance and the strength can be maintained even if the cloth is omitted. The purpose is to provide a storage bag.

[0005]

A storage bag according to the present invention is one in which an end portion of a fastener is extended and sewn together with a joint between a bag side surface and a bottom surface or a bag side surface and a back surface. That is, in the case of center opening with fasteners attached to the upper surface and both side surfaces of the bag, each end of the fastener is extended to the joint portion between the bag side surface and the bottom surface and sewn together with the joint portion, and the fastener is attached to the front surface and both side surfaces of the bag. In the case of the attached three-way opening, each end of the fastener is extended to the joint between the side surface of the bag and the back surface and sewn together with the joint.

[0006]

Since the end of the fastener is sewn at the joint between the side surface of the bag and the bottom surface or the back surface, it is possible to sew the cloth from the place where the fastener end is sewn to the bag bottom or the back surface, It is omitted and the fastener is attached only by the sewing process of the fastener.

In the sewing process of the fastener, a single-needle sewing machine can be used, but a two-needle sewing machine is preferably used so that the sewing can be performed simultaneously with the cloth on both side edges of the fastener. In the conventional storage bag, when sewn with a two-needle sewing machine, only the fastener end can be sewn, and it is necessary to sew with a single-needle sewing machine from the sewn point of the fastener end to the bottom surface or back surface before sewn with the fastener. However, since the fastener is attached until it reaches the bottom surface or the back surface of the bag, the above problem does not occur and the two-needle sewing machine can be used. By using a two-needle sewing machine, the fastener can be sewn in one step, and the sewing time can be halved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a center-opening storage bag 2 in which a fastener 1 is mounted over the center a of the bag and both side surfaces b and c on the left and right sides, and each end 3 of the fastener is extended to a side surface b or c. It is sewn at the same time when the joint portion with the bag bottom surface d is sewn, and FIG. 2 shows a three-way open storage bag 4 in which a fastener 4 is attached over the upper part of the front surface e of the bag 5 and the left and right side surfaces b, c. The ends 6 of the fastener are sewn at the same time when the side b or c and the sewn portion of the back face f are sewn together.

[0009]

As described above, the storage bag of the present invention has the fastener end extended to the cloth side surface or the joint portion between the cloth side surface and the back surface and sewn together with the joint portion. Since it is only necessary to sew, it is possible to omit the sewing work of cloth from the sewn portion of the fastener end to the bag bottom or the rear part, and the work of sewn cloth.
The time and effort for sewing the fastener part can be greatly reduced, and the appearance of the bag and the strength of the fastener end are not impaired by this. Further, the sewing of the fastener can be performed in one step using a two-needle sewing machine without impairing the appearance.
