[0008] The following are embodiments of the present invention, as shown in Figures 1 to 1. 7 This will be explained in detail based on [the relevant information].

[0009] The zipper opening and closing device 1 of the zippered bag consists of a sliding contact means 7, which has a pair of sliding contact parts 6 that slide against the outer surface of the zippered bag 5, which is equipped with a zipper 4 composed of a recessed groove 2 and a convex rib 3 that engages with the recessed groove 2, and a zipper opening and closing means 8 provided between the sliding contact parts 6 at the center position of the sliding contact means 7, and the length of the zipper opening and closing means 8 is set to penetrate between the recessed groove 2 and the convex rib 3 and be inserted into the inside 9 of the zippered bag. The outside of the zipper 4 is the outside of the bag 10.

[0010] The sliding contact means 7 has a base 11 that is bent into a triangular cross-sectional shape, and sliding contact portions 6 are formed at the four corners of the base 11, with each end being folded back in an annular shape. The edge of a pinch portion 12, which is used to spread the sliding contact portions 6 apart by pinching it with the fingers, is rotatably supported on the inner surface of the sliding contact portions 6. By pinching the pinch portion 12 with the fingers and spreading the sliding contact portions 6 apart, the sliding contact portions 6 can slide against the outer surface of the zippered bag 5. The sliding contact means 7 consists of the base 11 and the pinch portion 12. If the zipper opening / closing device 1 of the zippered bag is clip-shaped, it has the effect of maintaining airtightness because it is locked to the outer surface of the zippered bag 5 when the zipper 4 is closed and does not come off. Furthermore, if the clip-shaped sliding contact portion 6 is designed to lock outside the zipper 4, the sliding contact portion 6 does not get in the way, and it is possible to enclose the zipper opening / closing means 8 with the zipper 4, which has the effect of improving airtightness.

[0011] The zipper opening / closing mechanism 8 is located in the center of the ceiling plate 13 of the base 11, which is bent into a triangular cross-sectional shape. The zipper opening / closing mechanism 8 is set to be a rod-shaped body made of a material and thickness that does not bend during zipper opening and closing operations, and a diameter of 0.6 mm or more is desirable. The zipper opening / closing device 1 of the zippered bag can be manufactured from synthetic resin, and the zipper opening / closing mechanism 8 can also be formed from synthetic resin, and bonding or welding can be done as needed.

[0012] Zipper opening and closing device 21 of a zippered bag referenceFor example, as shown in FIGS. 4 to 6, the legs 23 that form a pair of the sliding contact means 22 face each other with a gap S of 1.4 millimeters therebetween. A sliding contact portion 24 is provided on the inner surface of the sliding contact means 22, and the legs 23 are fixed to the base 25 by means such as adhesion or welding. A rod-shaped chuck opening / closing means 26 is provided at the center of the base 25. The chuck opening / closing means 26 is bent so as to protrude and incline toward the side that moves when opening the chuck 4. By bending it so as to protrude and incline toward the moving side, an angle can be given to the chuck 4, and the chuck 4 can be opened with a small force. The gap S was not a problem even when it was 1.9 millimeters, but when it was 2.4 millimeters, it was too wide and the usability deteriorated. The chuck opening / closing device 21 for the bag with a chuck is composed of the legs 23, the base 25, and the chuck opening / closing means 26, and may be integrally formed of a synthetic resin. Also, as shown in FIG. 7, the chuck opening / closing means may be provided directly on the sliding contact means 22 without a base. The tip of the leg 2 of 3 is curved outward to form a guide portion 27.

[0013] The chuck opening / closing means 8 and 26 of the chuck opening / closing device 1 for the bag with a chuck are formed of a rod-shaped body, but may be formed of a flexible string-like body. By making it a string-like body with a flexible diameter of about 0.17 millimeters, the chuck 4 can be closed with the chuck portion opening / closing means 27 entering the chuck 4, and the airtightness of the inside 9 of the bag can be maintained. When the chuck opening / closing means 27 is made string-like, it is desirable to provide a weight so that it does not fly up.
