Since operations such as touching and pushing the lid 102 and the upper box 110 are required, the workability is poor, and there is a risk of forgetting to lock the lid 102 and the upper box 110.

Furthermore, if the stops 109 and 116 are temporarily attached only to the lid 102 and the upper box 110, there is a risk that the stops 109 and 116 will be lost because they are likely to come off from the lid 102 and the like. There was a problem that the lock could not be locked if you were out and did not have a spare fastener.

[Means for Solving the Problems] In order to solve all the problems of the prior art described above, the present invention provides through holes 6 and 7 formed in a continuous manner at the overlapping portion of the container body 1 and the lid 4, and the through holes. It consists of a locking member 8 that is slidably inserted into 6 and 7, and the following a~
The present invention provides a lid lock structure for a container having the configuration f.

a. Make the through hole 6 of the lid 4 narrower than the through hole 7 of the container body 1.

Since the side surface of the hole 6 is tapered downward, if it is pushed in with strong force, the peripheral edge of the through hole 6 and the hanging piece 10 will bend to each other, and the side edge of the through hole 6 will move into the sliding groove 1.
Fits in 3. As a result, the locking member 8 is held without coming off from the lid 4, and is also able to freely slide within the through hole 6 in the longitudinal direction. Further, since the resilient piece 11 engages with the side edge of the through hole 6, the lock member 8 is biased toward the rear edge side of the through hole 6.

Next, when the lid 4 with the lock member 8 attached is placed over the container body 1, the rear surface of the hanging piece 10 of the lock member 8 comes into contact with the side edge of the through hole 7 of the container body 1. However, since the rear surface of the hanging piece 10 is tapered, as the lid 4 is lowered, the lock member 8 is gradually pushed forward against the bias of the resilient piece 11. And hanging piece 10
When most of the lock member 8 sinks into the through hole 7 of the container body 1 and the engagement groove 15 at the rear of the hanging piece 10 reaches the lower edge of the through hole 7, the elasticity of the elastic piece 11 causes the lock member 8 to move toward the rear side. the lid 4 and the container body 1 through the engagement groove 15.
The side edges of the through holes 6 and 7 are integrally held together.

On the other hand, when removing the lid 4, the cover plate 9 can be slid forward with a finger to disengage the engagement groove 15 and the through holes 6, 7, and then the lid 4 can be pulled upward.

[Examples] Examples of the present invention will be described below with reference to the drawings.

The container body 1 has a rectangular parallelepiped shape with an opening at the top, and a flange 3 that horizontally projects outward at the upper end of the side wall 2.
is provided.

The lid 4 has approximately the same shape as the opening of the container main body 1, and has a side edge 5 that is inscribed in the side wall 2 of the container main body 1 and is vertically provided on the lower surface of the lid 4. Through holes 6 and 7 are formed in the overlapping portion of the lid 4 and the flange 3 of the container body 1, respectively. The lengths of these through holes 6 and 7 are the same as shown in Fig. 3, and the width is the same as that of the lid 4 as shown in Fig. 4.
The width of the through hole 6 is narrowed, and the through hole 7 of the container body 1 is formed wider than that.

On the other hand, the lock member 8 is integrally molded from synthetic resin, and includes a contact plate 9 that comes into contact with the upper surface of the through hole 6 of the lid 4.
, a hanging piece 10 inserted into both the through holes 6 and 7, and a resilient piece 11 extending integrally from the lower end of the hanging piece 10.

The hanging piece 10 is formed to have approximately the same width as the through hole 6 of the lid 4 from the lower surface of the plate 9 to a height corresponding to the wall thickness of the lid 4, and the lower part thereof is formed in the container body 1.
By forming the lateral width to be approximately the same as the width of the through hole 7, a sliding groove 13 that engages with the side edge of the through hole 6 of the lid 4 is provided on the side surface of the base end of the hanging piece 10. Also, hanging piece 1
The side and rear surfaces of 0 are formed in a tapered shape that tapers downward from the contact plate 9 side.

A resilient piece 11 protruding from the lower end of the hanging piece 10
is curved from the lower end of the hanging piece 10 toward the front of the cover plate 9, and its tip engages with a through hole 14 bored in the front of the cover plate 9 to be held in an arcuate shape.

On the other hand, an engagement groove 1 is formed on the rear surface of the base end of the hanging piece 10 at a height equivalent to the thickness of the lid 4 and the container body 1.
5, the locking member 8 is pressed toward the rear side by the biasing force of the resilient piece 11, and the lid 4 and the peripheral edges of the through holes 6, 7 of the container body 1 are simultaneously inserted into the engaging groove 15.

Next, the action will be explained.

First, insert the hanging piece 1 of the locking member 8 into the through hole 6 of the lid 4.
0 is inserted and pressed, the part of the hanging piece 10 below the sliding groove 13 is thicker than the width of the through hole 6, so it does not pass through easily. However, hanging piece 1
Since the side surface of the hole 6 is tapered downward, if it is pushed in with strong force, the peripheral edge of the through hole 6 and the hanging piece 10 will bend to each other, and the side edge of the through hole 6 will move into the sliding groove 1.
Fits in 3. As a result, the locking member 8 is held without coming off from the lid 4, and is also able to freely slide within the through hole 6 in the longitudinal direction. Further, since the resilient piece 11 engages with the side edge of the through hole 6, the lock member 8 is urged toward the rear edge side of the through hole 6.

Next, when the lid 4 with the lock member 8 attached is placed over the container body 1, the rear surface of the hanging piece 10 of the lock member 8 comes into contact with the side edge of the through hole 7 of the container body 1. However, since the rear surface of the hanging piece 10 is tapered, as the lid 4 is lowered, the lock member 8 is gradually pushed forward against the bias of the resilient piece 11. And hanging piece 10
When most of the lock member 8 sinks into the through hole 7 of the container body 1 and the engagement groove 15 at the rear of the hanging piece 10 reaches the lower edge of the through hole 7, the elasticity of the elastic piece 11 causes the lock member 8 to move toward the rear side. the lid 4 and the container body 1 through the engagement groove 15.
The side edges of the through holes 6 and 7 are integrally held together.

On the other hand, when removing the lid 4, the cover plate 9 can be slid forward with a finger to disengage the engagement groove 15 and the through holes 6, 7, and then the lid 4 can be pulled upward. Even after the lid 4 is removed from the container body 1 in this manner, the lock member 8 is retained within the through hole 6 as it is.

If a protruding finger hook 16 is provided on the upper surface of the plate 9 as shown in FIG. 1, the operability when unlocking the locking member 8 can be improved. In addition, as shown in FIG. 5, a handle 1 is attached to the side wall of the container body 1.
