Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a closure used mainly for closing the mouth of a bag.

[0002]

[Prior Art]

 The mouth of the bag of mail to be sent overseas is wrapped in multiple layers and tightly tied, and the metal caulking metal fittings are used to crimp both ends of the bag so that the cord cannot be unraveled. It

[0003]

[Problems to be solved by the device]

 According to such a conventional sealing method, the workability is low because the caulking metal fitting must be attached after the string is tied, and the string does not loosen at all, so the contents are completely prevented from being pulled out. I couldn't.

The present invention has been devised in order to eliminate such inconveniences of the conventional technology, and its main purpose is to easily attach the closure and to obtain a high locking prevention effect. To provide.

[0005]

[Means for Solving the Problems]

 According to the present invention, such an object is to provide a top plate portion integrally formed with a highly flexible synthetic resin material, a pair of side plate portions hanging from the left and right side edges of the top plate portion, and a top portion. It consists of a belt part that extends rearward from the rear edge of the plate part, and the belt part folds along the peripheral edges of both side plate parts to block the rear surface, bottom surface, and front surface between both plate parts. It consists of a possible folding plate part and a binding part extending from the rear end of the folding plate part and having ratchet teeth having a sawtooth-shaped cross section formed on one surface. Holes through which the binding parts can be inserted are provided in the parts corresponding to the bottom surface of the plate part, and the ratchet teeth of the binding parts inserted into these holes can be elastically and non-reactively engaged. Achieved by providing a closure that is characterized in that ratchet pawls are provided between both side plates It is.

[0006]

[Action]

 According to this structure, the top plate portion, the side plate portion, and the folding plate portion form a box-shaped body having the ratchet pawls built therein. Then, the bundling part is rolled into a loop and wound around the mouth of the bag, and the end of the bundling part is inserted into the holes of the top plate and the bottom face facing the top part, and the end part is pulled to the full so that the bag part Is closed like a purse. In this state, the ratchet teeth of the binding portion and the ratchet pawl between the side plates engage with each other in a non-return manner, so that the binding portion is prevented from loosening. Moreover, the joint between the ratchet teeth and the ratchet pawl is completely hidden by the top plate, the side plate, and the folding plate, making it impossible to pry open.

[0007]

【Example】

 Hereinafter, a configuration of the present invention will be described in detail with reference to specific embodiments shown in the accompanying drawings.

FIG. 1 shows a main part of a bag closed by a closure of the present invention. The bag 1 is, for example, for accommodating airmail or the like, and the contents cannot be removed by squeezing its mouth into a purse-like shape and then tightening it with the closure 2. The closure 2 is integrally formed with a thread-like body 4 for forming a loop and connecting the tag 3 thereto.

The closure 2 is integrally formed of a highly flexible synthetic resin material and, as shown in FIGS. 2 to 4, is suspended from the top plate 5 and the left and right side edges of the top plate 5. A box-shaped body having an open bottom is formed by the pair of side plates 6 and ribs 7a and 7b connecting the facing surfaces of the side plates 6 along the front and rear edges of the side plates 6, and The belt portion 8 extends rearward from the rear edge. It should be noted that the above description regarding the directions is for convenience of description, and is not related to the directionality in actual use.

The belt portion 8 is divided into a wide folded plate portion 9 on the base end side connected to the top plate 5 and a narrow binding portion 10 on the free end side. The folding plate portion 9 is formed with three thin-walled hinge portions 11 including the portion along the rear edge of the top plate 5, and is bent from the hinge portion 11 with its lower surface facing inward. By bending the folding plate portion 9 along the peripheral edges of the side plates 6, a substantially rectangular parallelepiped whose entire surface is closed is formed at one end of the binding portion 10. Ratchet teeth 12 having a sawtooth-shaped cross section are continuously formed over a predetermined length on the upper surface of most of the binding portion 10, and a plurality of protrusions 13 are arranged in the longitudinal direction on the lower surface thereof. Further, a plurality of ridges 14 along the width direction are formed at equal intervals on both upper and lower surfaces on the most free end side of the binding portion 10.

On the lower surface of the top plate 5, that is, on the inside of the box-shaped body, ratchet pawls 15 that can engage with the ratchet teeth 12 in a resilient and non-returning manner are vertically provided. The ratchet pawl 15 faces a belt guide 16 formed on the inner surface of the rib 7a on the front edge side of the side plates 6. Then, a position aligned with the portion between the ratchet pawl 12 and the belt guide 16 between the top plate 5 and the bottom face facing the top plate 5 in the folded plate portion 9 bent along the peripheral edge of the side plate 6. Belt insertion holes 17 and 18 are provided in each of these.

A relatively short collar portion 19 extends from the front edge of the top plate 5, and the thread portion 4 described above extends forward from the collar portion 19. The thread-shaped portion 4 is formed with a pear-shaped pointed protrusion 4a at the free end thereof, and the collar portion 19 is formed with a slit 20 capable of receiving the pointed protrusion 4a. Further, a slit 21 for inserting the binding portion 10 is formed at the base of the collar portion 19.

Next, a description will be given of how to use the sealing device 2 described above. First, the folding plate portion 9 is bent along the peripheral edge of the side plate 6 with its lower surface facing inward, and the tip of the binding portion 10 is inserted into the slit 21 at the base of the collar portion 19 to completely fill the binding portion 10. Pull out to. As a result, the ratchet pawl 15 is completely contained in the box-shaped body.

Next, with the surface on which the ratchet teeth 12 are formed facing outward, the bundling portion 10 is rolled into a loop shape and wound around the mouth of the bag 1, and the free end side of the baffle portion 9 and the top plate 5 is folded. Insert into the insertion holes 17 and 18 on the bottom. Here, since a plurality of ridges 14 are formed at the free end of the binding portion 10, these are preferably caught by the insertion holes 17 and 18, and the binding portion 10 is temporarily fixed without elastically jumping up. .

Next, when the binding portion 10 is pulled to the full and the mouth of the bag 1 is squeezed, the ratchet claw 15 and the ratchet teeth 12 are engaged with each other, and the tight state of the mouth portion of the bag 1 by the binding portion 10 is maintained. Here, since the protrusion 13 is formed on the inner surface of the binding portion 10, this prevents the binding portion 10 from slipping and prevents the binding portion 10 from loosening (see FIG. 5).

In this state, the joint between the ratchet pawl 15 and the ratchet tooth 12 is completely hidden, so that it cannot be prying open from the outside.

[0017]

[Effect of the device]

 As described above, according to the present invention, since both ends of the binding portion that is closed by squeezing the mouth of the bag are tightened by the ratchet type non-return means, the loosening is surely prevented. In addition, a box-shaped body is formed in the part integrally formed with the binding part, which hides the connecting part between the ratchet pawl and the tooth, so that the internal structure cannot be seen from the outside. You will not be able to pry it without destroying it. Therefore, a great effect can be achieved in preventing unauthorized opening.
