〔Example〕

Hereinafter, preferred embodiments of the clip of the present invention as a bag clip will be described based on the drawings.

The bag clip of the present invention has two limbs 1 which are hinged at one end by a hinged connection part 12 with a snap-in structure.
, 2. The limbs have snap-on locking elements 8-10 at their other ends, by means of which the two limbs are fastened together.

This rim 1.2 is manufactured in each case as a one-piece construction from a plastics material of suitable elasticity or resilience, by known plastic molding or pressure molding techniques, but in particular from nylon 6.6, nylon Plastic materials selected from polyamides, polyethylene homopolymers and copolymers, polypropylene homopolymers and copolymers, such as 6.12, nylon 12, nylon 11, nylon 6; and polyoxymethylene, PET resin, PBT resin, are suitable for the purpose of the present invention. suitable.

Note that the walls 6a and 6b of the channel 4 may be constructed using an elastic body such as an elastomer or rubber.

Examples of elastomers include EVA, polyurethane,
Examples include polyester elastomer and polyamide elastomer.

A raised portion 19 extending from the bottom 18 of the rim 1 has a plurality of reinforcing ribs 5 extending outwardly along both sides thereof and perpendicular to the bottom 18 . The upper free end of the raised part 19 is formed with two mutually parallel legs 3a, 3b, which are separated from each other by a central channel 20 (see FIG. 3). These legs 3a, 3b can be three or more in order to improve the sealing performance of the clipped bag.

The other rim 2 has two legs 5a standing upright from the bottom of the rim.
, 5b, the edges of these legs are tapered at 7. Legs 6a, 6b and 3a, 3b
in cooperation with the tapered portion 7, the legs 3
a, 3b are pressed in the direction facing each other and guided by the tapered part 7 on the one hand to tightly press the bag, for example the part of the plastic bag 22 (see FIG. 5) inserted between the rims, between the rims. Configured to tighten. The channel 4 is wider than the other channel 20 with upright free channel walls, and the walls 3a, 3b of the narrower channel 4 are connected to the walls 5 (1, 3b) of the wider channel 4.
6b, it is configured to be pushed together with the bag portion between these walls. wall 3a of channel 20,
3b and the walls 6a, 6b of the channel 4 are formed in such a shape and dimension that when they are fitted together, they create a margin after fitting in response to changes in the thickness of the bag. The walls 3a, 3b of the narrow channel 20 are the walls 5a, 6b of the wide channel 4.
The upper surfaces of the walls 5a, 5b of the wide channel 4 are formed with a tapered portion 7, so that the channel 4 is biased along the height of its walls 6a, 6b. The area above it is wider than the area below it. As shown by the symbol 16°15,
Both ends of rim 1 are rounded, and rim 2 is similarly rounded.
The end 17 adjacent to the fold 12 is rounded. Of course, it may not be rounded, but may be at a right angle. The free end 15 of the rim 1 is formed with an outwardly projecting shoulder 8.

A fastening tab is formed at the free end of the rim 2, and the top end thereof has a serrated tongue piece 10 for releasing the fastening action between the rims 1 and 2. This tongue lO is connected to the bottom 21 of the rim 2 via the shaft 11 and the knuckle bend 9. At the bottom of the tongue 10 or below the tongue 10 facing the shaft 11, there is provided another shoulder 13, which is connected to the fastening shoulder of the rim 1, as shown in FIG. 8 and is configured to be in an engaged state. The rim 2 terminates at its free end in an upright wall 14.
extends at right angles to both the bottom 21 and the legs 5a, (ib). When the rims 1 and 2 are moved relative to each other to a sufficient extent, these rims are automatically fastened together at their free ends and the rims In order to release them, it is necessary to hold the tongues 10 at right angles and downwards, as can be seen from FIG.

In the present invention, as described above, the two rims 1 and 2 are hingedly connected at one end by a hinged connection part 12 of a snap-in structure. A clip in which the end portions are integrally connected to each other by integrally molded notched bent portions and is hinged has already been proposed in Japanese Patent Application No. 62-275217, but the actual effective length of the hinge method is 70 m/m. When designing the above-mentioned clip, the mold becomes large and the mechanism becomes complicated, which is disadvantageous because it increases the cost.

The inventors have determined that the actual effective length (the actual length of the clip 0)
In the case of a lip with a length of 50 m/m or an actual effective length of 210 m/m, we have found that it is more advantageous to adopt a rotatable hinge system rather than a hinge type, and have arrived at the present invention.

Various known types of hinge type connections with a fitting structure can be employed, examples of which are shown in FIGS. 6(a), (b), and (C). In FIGS. 6(a) and 6(b), at the corresponding ends of the rims 1 and 2, a longitudinal groove 12a (IJ rim 1) and a protrusion 12b (IJ rim 2) that fits into the groove are formed. A horizontal receiving hole portion 12C and a protruding shaft portion 12d that fits into the receiving hole portion 12C are formed on the side surfaces of the groove portion 12a and the protruding portion 12b that face each other. If the ends of the rims 1 and 2 molded from thermoplastic resin are softened by raising the temperature and fitted so that the protruding shaft portion 12d enters the receiving hole portion 12c,
Both are integrally and hingedly connected to be rotatable about the protruding shaft portion 12d.

In Fig. 6(C), on the contrary, the groove 12a (!Jmu1)
A protruding portion 12d'' is formed on the inner surface of the rim, and a receiving hole 120' is formed on the outer surface of the protruding portion 1211 (rim 2) facing the protruding portion 12d'', and the protruding portion 12d'' fits into the receiving hole 12C''. , a hinged joint with a telescoping structure is formed.

As shown in FIGS. 1 and 2, the clip of the present invention may have protuberances made of several lines on the outer surfaces of the rims 1 and 2 to prevent slipping, or The retainer on the outer surface adjacent to the snap-locking element may be provided with a finger cleat that bulges toward the snap so that the clip can be fastened with a single touch.

You can also attach a retaining ring to make it a hang type. Furthermore, a holding magnet may be integrally attached to the outer surface of the rim 1 or 2 in order to allow the clip of the present invention to be installed at any location and used as required.

On both longitudinally outer sides of the rims 1 and 2, first
．． Although reinforcing ribs 5 as shown in FIG. 2 can be provided, the shape of these ribs is arbitrary, and of course they do not need to be provided. Several examples of preferable rib shapes are shown in FIGS. 7(a) to 7(e).

〔Effect of the invention〕

When the clip of the invention is used as a bag clip, it can be used with narrow bag widths not exceeding its length, and in the case of wide bags, with the upper part of the bag or the neck of the bag. The sections may be used by folding or twisting them together before placing the clip around them. The illustrated clip construction also allows the bag to be tightly sealed, thus preventing the contents from leaking out of the bag.

Plastic materials forming the clip of the present invention include nylon 6/6, nylon 6/12, nylon 12, nylon 11, nylon 6, polyethylene homopolymers and copolymers, polypropylene homopolymers and copolymers, and polyoxymethylene, as described above. Although the selected plastics have excellent features, it is also possible to fill these plastics with inorganic fillers to improve rigidity, heat resistance, dimensional stability, etc.
