Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a handle in which a clamping part provided at the tip of the handle body is clamped and fixed to the mouth edge of a packaging bag, etc. This invention relates to improvement of the holding part.

(Prior Art) Conventionally, there have been handles in which a clamping part provided at the tip of the handle body is clamped and fixed to the mouth edge of a packaging bag, etc., and there are various types of handle bodies. There are some in the form of a finger hanger, and others in the form of a string with clamping parts at both ends.

(Problems to be solved by the invention) Among the above-mentioned conventional products, the structure of the clamping part is simple, for example, by simply providing opposing protrusions and holes on the clamping surface and attaching the protrusions to the mouth edge of the packaging bag. In the case of a device in which both clamping pieces are fitted after being inserted into a drilled mounting hole, the clamping force is weak, so it is not only unsuitable as a handle for heavy objects, but also can be attached to the edge of the bag. There is an inconvenience in that it cannot be attached unless it has a mounting hole drilled in it, and it also has the disadvantage that the mounting hole may tear.

In addition, in a structure in which a lever is provided on the clamping part and the lever is used to forcibly approach and clamp opposing clamping pieces, the structure is generally complicated and the lever and other members are separate members. Since the system incorporates these components, it has disadvantages such as increased costs.

The purpose of the present invention is to eliminate the above-mentioned drawbacks of the conventional products, and the structure of the clamping part is simple, and it can be easily clamped and fixed to the mouth edge of the packaging bag without the need for mounting holes. The object of the present invention is to provide a handle which has an extremely strong clamping force, can be fixed accurately, and can be integrally molded as a whole, thereby significantly reducing costs.

(Means for Solving the Problems) The handle of the packaging bag, etc. according to the present invention is such that the gripping part provided at the tip of the handle body is clamped and fixed to the mouth edge of the packaging bag, etc. The clamping part is integrally molded with two opposing clamping members each having a pressing piece formed on the rear end side and a clamping piece formed on the distal end side, and connecting the two clamping members at the midsection of both clamping members. a connecting piece, biting teeth formed on opposing surfaces of both the clamping pieces, and one pressing piece formed on the rear side of the connecting piece; A thin hinge part is held so that the entire member forms a substantially dogleg shape, and a thin hinge part is formed on the inner surface of one of the above-mentioned pressing pieces, and when both pressing pieces are pressed, the tip part of the pressing piece presses the other one. The lever part is designed to slide on the inner surface of the piece and maintains the "dog" shape when its tip is in contact with the inner surface, and the lever part is designed to slide on the inner surface of the piece. It has a lever locking part that protrudes from the surface, and the entire body is integrally molded from synthetic resin.

(Function) When the opening edge of the packaging bag is inserted between the two opposing clamping pieces and pressed so as to sandwich one pressing piece and the other pressing piece that are wide open at the thin hinge part, one side The tip of the lever portion protruding from the pressing piece comes into contact with the inner surface of the other pressing piece, but in this state, one of the clamping members is still slightly dogleg-shaped.

When both pressing pieces are further pressed, one of the clamping members becomes straight, while the tip of the lever part slides on the inner surface of the other pressing piece, and eventually the one clamping member becomes shaped like an inverted dogleg. The mouth edge etc. are strongly clamped with both clamping pieces facing each other. At this time,
The change in distance between the fulcrum at the tip of the lever part and the upper end of the connecting piece can be absorbed by the flexibility of the connecting piece, and the inverted dogleg shape is maintained by the elasticity of the connecting piece. When the tip passes through the lever locking portion, it is locked and the clamped state is maintained. Since biting teeth are formed on the inner surfaces of both clamping pieces, these bite into the mouth edges, etc.
Even if it is a packaging bag or the like having a synthetic resin film, the clamping pieces can be accurately fixed without slipping.

The entire clamping part is integrally molded from synthetic resin, and no separate parts are incorporated, which can significantly reduce costs.If the handle body is integrally molded into the clamping part,
It is possible to further reduce costs.

(Example) An example of the handle of a packaging bag or the like according to the present invention will be described based on the drawings. The clamping part 3 is clamped and fixed to the mouth edge 22 of the packaging bag 21.

The holding portion 3 has pressing pieces 6 and 7 on the rear end side.
However, there are two opposing clamping members 4 and 5 with clamping pieces 8 and 9 formed on the distal end sides thereof, and a connection molded integrally to connect the two clamping members 4 and 5 at the midsections of both clamping members 4 and 5. piece 10, biting teeth 11 and 12 formed on opposing surfaces of the clamping piece, and one pressing piece 6 formed on the rear side of the connecting piece 10, so that the one clamping piece 6 is wide open. A thin hinge portion 13 that holds one of the clamping members 4 as a whole in a substantially dogleg shape, and an inner surface 16 of one of the pressing pieces, 6 in the embodiment.
By pressing both pressing pieces 6 and 7, the tip 15 of the pressing piece 7 touches the inner surface 17 of the other pressing piece 7.
The lever portion 14 is designed to slide and maintain the dogleg shape when its tip 15 is in contact with the inner surface 17.
and a lever locking portion 18 formed on the sliding surface of the inner surface 17, and the whole is integrally molded from synthetic resin. In addition, it is preferable to provide a plurality of the above-mentioned upper and lower biting teeth 11, 12 with their positions alternately shifted.

There are various kinds of handle bodies 2 described above, but in this embodiment, the above-mentioned clamping parts 3 are provided at both ends of a string-like handle body. The handle main body 2 and the holding part 3 can be integrally molded, and as a result, the entire handle 1 can be integrally molded, so a special mold is not required, and costs can be significantly reduced.

When using the handle configured as described above, insert the mouth edge 22 of the packaging bag 21 between the opposing clamping pieces 8 and 9, and as shown in FIG.
When one pressing piece 6 and the other pressing piece 7, which are widely opened by the thin hinge portion 13, are pressed so as to sandwich them, one pressing piece 6 changes from the state shown in FIG. 5A to the state shown in FIG. 5B. The distal end 15 of the lever portion 14, which is protruded in this manner, comes into contact with the inner surface 17 of the other pressing piece 7, but in this state, one of the holding members 4 is still slightly dogleg-shaped.

When both pressing pieces 6 and 7 are further pressed, one of the holding members 4 becomes straight, and the lever part 14
The tip end 15 of the pressing member 4 slides on the inner surface 17 of the other pressing piece 7, and eventually the one holding member 4 turns into an inverted “dog” shape and presses the mouth edge portion 22 with the opposing holding pieces 8, 9. etc. firmly. At this time, the change in distance between the fulcrum of the tip 15 of the lever portion 14 and the upper end of the connecting piece 10 can be absorbed by the flexibility of the connecting piece 10, and the elasticity of the connecting piece 10 allows the change in the distance The shape of the letter is maintained, and the tip end 1 of the lever part 14
5 passes through the stepped portion of the lever locking portion 18, the tip portion 15 is locked and the clamped state is maintained.

Both clamping pieces 8, 9 have biting teeth 11 on their inner surfaces.
12 is formed, this is the mouth edge 22.
Even if it is a packaging bag or the like having a synthetic resin film, the clamping pieces 8 and 9 can be accurately fixed without slipping.

(Effect of the invention) According to the handle of the packaging bag etc. related to the invention,
Insert the opening edge of the packaging bag between the two opposing clamping pieces, and press the wide open pressing pieces to sandwich them, and one of the pressing pieces will protrude. The tip of the lever part slides on the inner surface of the other pressing piece, and soon the whole of one clamping member becomes an inverted "dog" shape, and both clamping pieces firmly clamp and fix the mouth edge etc. You can also
By locking the lever portion with the lever locking portion, the clamped state can be maintained.

When removing it, you can easily release the clamped state by lifting one of the pressing pieces.
