JP3072363U - Binding material of bag mouth - Google Patents

Abstract

(57) [Summary] [Purpose] A binding material for sealing a squeezing opening of a bag for storing an article to be packaged, the binding material being recyclable integrally with the bag when the bag is recycled. Also formed by plastic. A polycarbonate wire rod is formed into a U-shape or a U-shape to form a tightening clip having a pair of parallel hands, and a cut is made in a substantially middle opposing portion of the entire length of the hands. It is composed. Cover the bag mouth with the U-shaped binding material and apply external force to the bag.
The pair of parallel hands 11 is cold-bent inward. in this case,
The wire 10 is plastically deformed, and the parallel hand 11 is cut 12
The part bends intensively. The fastening to the bag mouth does not loosen naturally due to the stickiness characteristics of polycarbonate.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a binding material that binds and tightens and seals a mouth of a packaging bag that stores an article to be packaged.

[0002]

[Problems to be solved by the invention]

 For example, it is important to bind bags containing moisture-containing foods or the like so that the moisture does not leak from the mouth of the bag. Therefore, as a binding material of this kind of package, an aluminum as shown in FIG. A U-shaped material is known as a material, which is bent as shown in FIG. 8 to bind the bag mouth. However, when recycling packaging containers, mixing metal such as aluminum into plastic containers requires a metal sorting process.

[0003] Therefore, it is easy to change the above-mentioned binding material to a plastic material, but since a thermoplastic or thermosetting plastic requires a sufficient cooling time, it is necessary to use these binding materials. The sealing process is inefficient, but when plastic is plastically deformed, the inherent elasticity of the plastic has the disadvantage that the fastening force at the bag mouth is naturally loosened.

[0004]

[Solution]

 According to the present invention, in order to maintain the tightening of the bag mouth, a polycarbonate wire rod 10 is formed into a U-shape or a U-shape as shown in FIG. 1 to form a tightening clip having a pair of parallel arms 11, and A cut 12 is made in each of the substantially middle opposing portions of the entire length of both hands 11.

After the U-shaped binding material is placed on the bag opening 20 narrowed down as shown in FIG. 4, an external force is applied to the binding material, and the pair of parallel arms 11 are cold-bent inward. In this case, as shown in FIG. 5, the wire 10 is plastically deformed. In particular, the parallel arm 11 is intensively bent at the cut 12 portion. Considering the mechanical properties of polycarbonate, it has so-called sticky material properties, and the bent part exceeding the elastic limit does not recover naturally, so the bag mouth can be tightened and held.

[0006]

[Embodiment of the invention]

 As shown in FIGS. 1 and 2, the binding material obtained by bending a round wire 10 having a diameter of 2 mm into a U-shape as shown in FIGS. 1 and 2 includes a pair of parallel hands 11 having a length 04 of 12 mm. Cuts 12 each having a depth 03 of 0.5 mm are formed in opposing portions 5 mm from the end. In some cases, as shown in FIG. 3, the wire 10 is formed into a U-shape. In both cases, the interval 05 between the two hands 11 is 9 mm, and the area occupied by the cut 12 with respect to the cross-sectional area of the wire 10 is 5% as shown in FIG. Or 30%.
