The receiving edge (A3) is formed at the position reached by the end surface of the container by tapering (T) from the outer circumference of the container body.

At the center position on the lateral side of the opening edge (A1), there is a bearing recess (A4) in which the shaft pin (S2) of the following locking device (C) is rotatably pivoted inward from the outside. Extruded,
This limits the level to the outer wall of the receiving edge (A2).

A shaft hole (S1) penetrating into the container main body is formed on both inner sides of the bearing recess (A4) on the same line, and the locking member (C) is provided.
Both shaft pins (S2) are fitted, the shaft is rotatably fixed, and the locking tool (C) is attached to the container body.

The lid body (B) is arranged outside the lid body (B) at a depth such that the opening edge (B1) reaches the outer peripheral edge (A3) at the end of the opening edge (A1) of the container body (A). It is extended to one side, and the protruding curved surface is used as a receiving edge (1B). With this as a surface, a narrow groove (B3) is formed at a position where the locking tool (C) engages, and this length is Make it slightly longer than the length of the standing piece of the locking tool (C) described below.

The shape of the locking groove (C) to be attached to the container body (A) is such that the length and width are such that all four fingers except the thumbs can be easily engaged from both sides parallel to the longitudinal direction of the substrate (C1). The opposite standing pieces (C2) (C3) are formed, the finger hanging edge (C4) is formed on the base, and both ends of one standing piece (C2) are parallel to the longitudinal direction of the substrate (C1). A shaft pin (S2) is projected on the wire.

In the figure, (D) is a bearing of a holding frame (H) formed on both sides of the opening edge (A1) of the container body (A), and a pair of shaft holes (D1) are bored in this bearing.

[Action]

Since the locking tool (C) of the present invention is configured as in the above embodiment, the lid body (B) is covered on the container body (A), and the opening edges (A1) and (B1) are overlapped inside and outside. End face, that is,
The end surface of the opening edge (A1) abuts on the inner step surface of the lid (B), and the end surface of the opening edge (B1) of the lid (B) abuts on the receiving edge (A3) of the container body (A). Is a fitting combination, and in order to prevent them from coming off, the locking tool (C) is a locking hole (S1) and the locking pin (S2) is a fulcrum. C) is pulled up to the outer peripheral edge (B2) side of the lid (B) and one standing piece (C3) of the locking tool is received on the edge (B2) of the lid (B).
It is placed on top and both are locked.

When releasing the locking tool (C), it can be easily and lightly released by putting a finger on the finger hanging edge (C4) of the locking tool and rotating the locking tool with the shaft as a fulcrum.

Also, when carrying the container body (A), place four fingers on the standing pieces (C2), which are the lower surfaces of both locking tools (C), and attach the thumbs to the standing pieces (C3) on the upper surface. When used as a hand, the edge (B) of the lid (B) of the locking tool (C)
The load of the container main body is exerted on the end of the standing piece (C3) engaged with 2), and it is possible to reliably prevent the lid (B) from coming off when carrying the container main body.

This action is achieved by making the shape of the locking tool U-shaped in cross section and projecting a shaft pin on one of the upright pieces so that the shaft hole (S1) of the bearing recess (A4)
When the locking device is used as a handle instead of the locking device, the load of the container main body is tilted forward with the shaft of the locking device (C) as a fulcrum. Since the standing one end is locked so as to fall into the narrow groove (B3) of the receiving edge, the locking action is strengthened, and the detachment of the lid (B) is exhibited during transportation of the container body.

In addition, since the locking tool has finger hooking edges (C4) formed on the bases of both standing pieces (C2) (C3) of the board (C1), finger hooking is secure, and the locking and unlocking action of the locking tool is achieved. Has an effect that can be reliably achieved.

[Effect of device]

Since the present invention is constructed as described above, firstly, the locking tool can also be used as a handle of the container body.

Secondly, the locking tool has a U-shaped cross section and is axially fixed to the standing piece and the container body so that the locking tool can be raised and lowered, and the other standing piece is locked to the receiving edge of the lid. Therefore, the locking and unlocking action of the locking tool is extremely reliable and easy.

Thirdly, when the locking device is used as a handle for carrying the container body, due to the structure of the locking device, the load of the container body causes the one end of the locking device to fall into the narrow groove of the receiving edge of the lid. Therefore, when carrying the container body, there is no possibility that the lid will come off from the container body.

Fourthly, since the locking tool is formed with a finger hanging edge, it has a simple structure such as a locking and releasing action of the locking tool, and a beneficial effect when carrying it. It has a practical effect.
