Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a bag that can be opened and closed with a fastener.

[0002]

[Prior art]

 In a bag to which a fastener is attached, the force of pulling the slider acts every time the fastener is opened and closed, so that there is a problem that the fastener attachment point in the base of the bag body is easily damaged. In addition, this type of bag usually has earpieces attached to its gusset. These ear pieces are used to hold the bag body with fingers so that the bag body does not move when pulling the slider of the fastener. And, the conventional ear piece is a single member, and its mounting is troublesome.

[0003]

[Problems to be solved by the device]

 Therefore, an object of the present invention is to provide a novel bag in which the fastener attachment point is strong and does not have a risk of being damaged, and the earpiece attachment is not troublesome.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the bag of the present invention has a long hole 10 formed in a base body 9 integrally forming at least the upper surface portion 6 of the bag body 5 and the gusset portions 7 and 8 on both sides. A long hole 11 is formed in the central portion, and a strip-shaped body 3 in which ear pieces 1 and 2 are integrally projected is formed at both ends in the longitudinal direction, and the strip-shaped body 3 is formed on the outer surface side of the base body 9 by the long hole 10. , 11 are overlapped with each other in position, and further, the fastener 4 is overlapped on the inner surface side of the base body 9 so as to close the long holes 10, 11 of the base body 9 and the strip-shaped body 3, and the periphery of the long hole 10 of the base body 9 is overlapped. In this section, the band-shaped body 3, the base body 9 and the tape 12 of the fastener 4 are integrally fixed, and the ear pieces 1 and 2 at both ends of the band-shaped body 3 are made free without being fixed. To do.

[0005]

[Action] Since the belt-shaped body 3 is superposed and integrally fixed to the attachment portion of the fastener 4, that is, the peripheral portion of the elongated hole 10 of the base body 9, the reinforcing effect is produced and the damage is less likely to occur. Further, since the earpieces 1 and 2 are integrally provided on the belt-shaped body 3 beforehand, if the belt-shaped body 3 is attached to the base body 9 of the bag body 5, the earpieces 1 and 2 are simultaneously attached to the bag body 5. Since it has been attached to the earpieces, the trouble of attaching the earpieces 1 and 2 is eliminated.

[0006]

【Example】

 Hereinafter, one embodiment of the present invention illustrated will be described. This embodiment shows a small bag that can be held. First, as shown in FIG. 2, it is made of a sheet of thermoplastic resin such as vinyl chloride and has a strip shape that constitutes the upper surface portion 6 of the bag body 5, the gusset portions 7 and 8 on both sides, and the bottom surface portion 14 in series. The base body 9 is provided with the long holes 10 at the upper surface portion 6 and the upper half portions of the gore portions 7 and 8 on both sides. Similarly, as shown in FIG. 2, a strip-shaped body 3 made of the same material as that of the base body 9 and having a long hole 11 formed at the center and ear pieces 1 and 2 protruding from both ends in the longitudinal direction, respectively. To form. Then, the strip 3 is superposed on the outer surface side of the base body 9 with the positions of the long holes 10 and 11 aligned. Then, the outer peripheral end of the strip 3 is integrally welded to the base body 9. In the figure, the portion indicated by reference numeral 15 is this welded joint. At this time, the ear pieces 1 and 2 at both ends of the strip 3 are not welded and are kept in a free state. Next, the fastener 4 is superposed on the inner surface side of the base body 9 in such a manner that the base body 9 and the elongated holes 10 and 11 of the strip 3 are closed. Then, the strip 3, the substrate 9 and the tape 12 of the fastener 4 are integrally welded to each other at the peripheral portion of the elongated hole 10 of the substrate 9. In the figure, the portion indicated by reference numeral 13 is this welded joint. The base body 9 to which the strip-shaped body 3 and the fastener 4 are fixed in this manner is then integrally bonded to the other base bodies constituting the front body portion 16 and the rear body portion 17, respectively, and the bag shown in FIG. Is completed.

[0007]

[Effect of device]

 The present invention is as described above, and the base body 9 integrally forming at least the upper surface portion 6 of the bag body 5 and the gusset portions 7 and 8 on both sides is formed with the elongated hole 10, and the elongated hole 11 is also formed in the center portion. A strip-shaped body 3 is formed by integrally projecting the earpieces 1 and 2 at both ends in the longitudinal direction, and the strip-shaped body 3 is aligned on the outer surface side of the base body 9 between the long holes 10 and 11. Then, the fastener 4 is superposed on the inner surface side of the base body 9 so as to close the base body 9 and the long holes 10 and 11 of the base body 3, and the belt body 3 and the base body 9 are attached to each other at the peripheral edge portion of the base body 9. And the tape 12 of the fastener 4 are integrally fastened, and the ear pieces 1 and 2 at both ends of the band-shaped body 3 are in a free state without being fastened. It is possible to make the mounting point of 4 strong and prevent damage. And one in which an effect that can be eliminated troublesome mounting ear pieces 1 and 2.
