[Technical field to which the device belongs]

 The present invention attaches a locking body having a rotatable locking piece to the body side of a bag or bag, and a locked body having an insertion hole into which a locking piece can be inserted on the lid side of a bag or bag. Mounting, insert the locking piece into the insertion hole, and rotate the locking piece to lock the locked body, and lock the lid of the bag or bag to the main body to stop the lid. Regarding the base.

[0002]

[Prior art]

 The main body a of the locking body A of the conventional bag and the mouthpiece of bags of this type is elliptical upward from the mounting portion 2 having the mounting hole 1 for the bag as shown in FIGS. Two grooves 4 and 5 intersecting at right angles to each other are formed in the raised surface 3, and a hole 6 is formed at the intersection of the grooves 4 and 5.

As shown in FIG. 9, the locking piece b is provided with a protrusion 7 on the lower surface of the knob portion 8, and a shaft 9 is formed at the center of the protrusion 7 on the lower surface of the knob portion 8. There is something.

After inserting the shaft 9 into the hole 6 of the raised surface 3 in the mounting portion 2, a washer 11 is fitted to the shaft 9 with a compression spring 10 interposed below the raised surface 3 to The locking piece A is constructed by attaching the locking piece b to the locking body a in a rotatable state by caulking the center hole 12 formed at the tip end to be enlarged.

On the other hand, as shown in FIGS. 10 and 11, the main body c of the locked body B is formed to have substantially the same inner shape as the outer shape of the knob portion 8, and bending claws 13 are provided at two opposite positions. The projecting upright collar 14 is upright at the center of the plate portion 15. The upright collar 14 of the main body c is fitted into the hole formed in the bag or the lid C of the bag or the like.

Next, an insertion hole 16 having the same internal shape as the outer shape of the upright collar 14 is formed in the seat plate d at the center of the plate portion 17, and at a position corresponding to the bending claw 13 with respect to the plate portion 17. A recess 18 is provided, the insertion hole 16 of the seat plate d is fitted into the upright collar 14 inserted into the hole of the lid C, and the bending claw 13 is bent in the recess 18 to lock the locked body. B is constructed and fixed to the bag and the lid C of bags.

The locking body A is attached to the bag, the bag on which the locked body B of the lid C of the bag is overlapped, and the rivet 19 inserted into the mounting hole 1 at the position of the body of the bag, and the locking body A is attached. After inserting the knob portion 8 of the locking piece b of the above into the hole formed by the upright collar 14 of the locked body B, the knob portion 8 is rotated by 90 degrees so that the two angles are eclipsed, The part 8 is prevented from coming off, and the lids of bags and bags are not opened.

[0008]

[Problems to be solved by the device]

 In such a bag or bag mouthpiece, the seat plate 11 for locking the spring 10 is fitted on the shaft 9, and the center hole 12 of the shaft 9 is enlarged by caulking work to attach the spring 10. There is a problem that the gap with the raised surface 3 changes each time the caulking work is performed, the compression force of the spring 10 varies depending on the product, and the caulking is excessively crushed or the amount of crushing is small so that the product is not constant.

Since the present invention intends to solve the above-mentioned problems, its purpose is to replace the troublesome work due to the caulking work and the variation of the product with a simple work of just fitting the speed nut. The company intends to provide a base for bags and bags that can improve the production efficiency and reduce the unit price of products.

[0010]

[Means for Solving the Problems]

 The bag and bag mouthpiece of the present invention is intended to achieve the above-mentioned object, and the means is to insert the bag or bag book into the insertion hole of the body to be inserted attached to the bag or bag lid. Insert the knob that rotatably attaches the shaft into the main body that is attached to the body side, and rotate the knob to lock the locked body. A thick shaft and a thin shaft are formed by a step portion, a spring is inserted into the thick shaft, and a speed washer having a plurality of cuts formed around a hole having a diameter smaller than that of the thin shaft is formed in the thin shaft. It is fixed by inserting it into the shaft.

[0011]

[Embodiment]

 Next, an example of an embodiment of the present invention will be described below with reference to FIGS. Also in this embodiment, the main body part a and the locking piece b of the locking body A, and the main body c and the seat plate d of the locked body B are the same as those of the bag and the bag mouthpiece.

Further, the shaft 9 is also formed in two steps in thickness, and the spring 10 is fitted to the thick shaft 9 a, but it is not necessary to form the central hole 12 in the shaft 9.

As in the conventional case, instead of the seat plate 11 attached to the shaft 9 by the enlarged caulking of the central hole 12, the peripheral edge of the hole 20 slightly smaller than the outer diameter of the thin shaft 9b provided at the center is provided. A speed washer e is used in which radial cuts 21 are formed and each piece 22 between the cuts 21 is formed of a strong elastic thin plate such as spring steel that bulges toward one surface.

When the bulging side of each piece 22 of the speed washer e is set to the opposite side of the thick shaft 9a and the thin shaft 9b is fitted, the respective pieces 22 are slid, so that the fitting operation can be performed without trouble. On the other hand, even if it is attempted to pull it out to the opposite side, each piece 22 will bite into the thin shaft 9b and will not come off.

Therefore, even if the pressing force of the spring 10 is applied to the speed washer e, it cannot be removed, the spring 10 can be reliably supported, the need for caulking work is eliminated, and the speed washer e Since the gap with the raised surface 3 is constant due to the stepped portion of the shaft, the spring force of the spring 10 is constant and the product variation is eliminated.

[0016]

[Effect of device]

 As described above, the present invention can eliminate the work of crimping the seat plate fitted on the shaft by the speed washer, and the position where the speed washer is fitted is restricted by the stepped portion of the shaft, and the work is easy and can be done in a short time. As a result, work efficiency is improved, production efficiency is improved, cost is reduced, and product variation is eliminated.
