BACKGROUND ART Conventionally, various containers for storing cosmetics and the like have been developed and put into practical use. Among them, recently,
There are compacts on the market in which an inner lid is attached to the inside of an outer container composed of a container body and an outer lid to separately store cosmetics and cosmetic puffs. As such a thing, for example, there is one as shown in FIG. That is, as shown in the figure, this compact has a shallow dish-shaped container body 1 containing cosmetics on the upper surface, and an outer lid 2 that covers the upper surface of the container body 1 hinged at the rear end. Inside the outer container,
It is configured by hinge-connecting an inner lid 3 having a mirror 3a attached to its lower surface. A concave portion 4 having an open upper surface is formed on the front wall surface of the container body 1, and an engaging projection 6 that engages with the engaging claw 5 of the outer lid 2 is provided on the inner surface of the concave portion 4 so as to project from the left and right sides. A shaft hole 7 is formed on both side surfaces. A shaft body 8 supported by the shaft hole 7 has an operating piece 9 projecting from both left and right side surfaces thereof.
Is rotatably mounted in the recess 4. When applying makeup using the compact, the operation piece 9 is pushed in the depth direction of the recess 4 to rotate the operation piece 9 around the shaft body 8 as shown by an arrow A. As a result, the upper surface of the operation piece 9 pushes up the lower surface of the front end portion of the outer lid 2, disengages the engagement protrusion 6 and the engagement claw 5, and the outer lid 2 is slightly opened. From this state, the outer lid 2 is lifted to expose the upper surface of the inner lid 3, and the puff 10 placed on the upper surface of the inner lid 3 is picked up by hand. Then, the inner lid 3 is lifted up to expose the cosmetic material of the container body 1. In this state, the cosmetic is transferred to the puff, and makeup is performed while looking at the mirror 3a attached to the back surface of the inner lid 3.

[Problems to be solved by the device]

However, the above compact does not have a mechanism for holding the inner lid 3 with the upper surface of the container body 1 covered.
For this reason, when the compact is inverted during carrying, etc., the inner lid 3 moves to the outer lid 2 side and a gap is created between the container body 1 and the inner lid 3, so that the cosmetic material in the container body 1 is removed from the gap. Inner lid 3
There is an inconvenience that it flows between the outer cover 2 and the outer cover 2. Further, in the compact, the operation piece 9 is attached to the recess 4 by utilizing the shaft body 8 of the operation piece 9. Therefore, when the engagement claws 5 of the outer lid 2 and the engagement protrusions 6 of the container body 2 are firmly engaged, the force pressing the operation piece 9 acts on the shaft body 8 and the shaft body 8 moves. The operation piece 9 is dropped from the shaft hole 7 and the operation piece 9 is recessed 4
There is an inconvenience that it comes off.

This invention was made in view of such circumstances,
Providing a lid opening / closing mechanism for a container that can fix the inner lid to the container body by closing the container and can properly open and close the outer lid and the inner lid without damage even if the opening / closing operation is repeated. Is its purpose.

[Means for solving the problem]

To achieve the above object, a lid opening / closing mechanism for a container according to the present invention comprises a container body, an inner lid and an outer lid hingedly connected to a rear end of the container body, and a notched recessed portion at a front end portion of the inner lid. A guide portion is provided on the inner wall surface of the cutout recess, and the operation piece accommodated in the cutout recess is engaged with the guide portion so that the operation piece can be moved back and forth in the cutout recess. The operation piece is provided with a notch concave portion on the back surface thereof, an engaging portion is provided on a portion of the front wall surface of the container body corresponding to the notch concave portion, and an engaged portion that engages with the engaging portion is the outside. A configuration in which the lower end edge of the back surface of the operation piece is formed as a downward taper surface that slides in contact with the engagement portion, and the upper end edge is formed in an upward taper surface that slides in contact with the engaged portion, provided at the front end portion of the lid. Take

[Operation] That is, in order to change the container provided with the lid opening / closing mechanism from the closed state to the open state, the operation piece attached to the notch recess of the inner lid so as to be movable back and forth is pressed in the depth direction of the notch recess. As a result, the operating piece is guided in the engaging portion by the guide portion of the cutout recess and moves in the depth direction of the cutout recess. Simultaneously with this movement, the upwardly tapered surface of the operation piece pushes the engaged portion of the outer lid upward, and the downwardly tapered surface of the operation piece bends the engagement portion of the container body rearward. As a result, the engagement between the engaging portion and the engaged portion is released, and the outer lid and the inner lid are slightly opened. From this state, the outer lid is pushed up and rotated backward to expose the upper surface of the inner lid. Then, the inner lid is pushed up and rotated rearward to expose the upper surface of the container body. In order to close the container in the open state, the outer lid is pushed down, and the engaged portion of the container body is engaged with the engaged portion thereof through the notched concave portion of the operation piece. Easy to do.

Next, this invention will be described in detail based on embodiments.

〔Example〕

FIG. 1 shows one embodiment of a compact using the container lid opening / closing mechanism of the present invention. That is, as shown in the figure, this compact includes a plastic container body 11 having an open upper surface, and a plastic inner lid 12 and outer lid 13 hinged to the rear end of the container body 11. There is. The outer lid is provided on the front wall of the container body 11 approximately at the center.
An engaging claw 15 that engages with an engaging claw 14 that is vertically provided at a substantially center of a front end portion of 13 is provided upright. Reference numeral 13a is a mirror attached to the back surface of the outer lid 13.

The inner lid 12 has a flange portion 16 formed at the upper edge thereof, and a notch recess 17 formed at the front end portion thereof. A guide piece 18 is provided on the inner surface of the cutout recess 17 so as to project left and right, and a guide protrusion 19 is provided on both left and right surfaces. 20
Is an operation piece attached to the cutout recess 17, and as shown in FIG. 2, a vertical piece 20a made of plastic and having a horizontally long plate shape,
It is composed of a horizontal piece 20b which extends vertically rearward from the upper end of the back surface thereof, and wall portions 21 which are provided on both left and right end surfaces of the vertical piece 20a and the horizontal piece 20b. A notch concave portion 22 for allowing the engaging claw 15 of the outer lid 13 to come in and out is formed substantially at the center along the longitudinal direction of the horizontal piece 20b, and the guide convex portion is formed on the outer wall surface of the left and right wall portion 21. A laterally long engagement recess 21a that engages with 19 is provided. Then, the corners on the outer wall surface side of the left and right wall portions 21 are chamfered along the vertical edges to form inclined surfaces 21b. As a result, when the operation piece 20 is attached to the cutout recess 17, the guide projection 19 can be smoothly fitted into the engagement recess 21a. Reference numeral 23 denotes a guide piece, which is provided on the left and right of the vertical piece 20a so as to be located below the horizontal piece 20b. And this guide piece
The guide piece 18 of the cutout recess 17 is loosely fitted in the gap 23a between the 23 and the horizontal piece 20b. Reference numeral 24 denotes a pressing portion provided from the deep portion of the cutout concave portion 22 to a portion of the vertical piece 20a, and as shown in FIG. 3, the compact is in sliding contact with the engaging claw 15 of the container body 11 in the closed state. Thus, the lower end edge is formed on the downward taper surface 24a, and the upper end edge is formed on the upward taper surface 25 so as to be in sliding contact with the engaging claw 14 of the outer lid 13.

The operation piece 20 uses the inclined surface 21b of the wall portion 21 to engage the guide convex portion 19 with the engagement concave portion 21a, and at the same time, the guide piece 18 of the cutout concave portion 17 with the gap portion 23a. By being loosely fitted, it can be attached to the notched recess 17 so as to be able to move back and forth.

In order to change the thus constructed compact from the closed state shown in FIG. 3 to the opened state, the operation piece 20 is pressed in the depth direction of the cutout recess 17. As a result, the engaging recess 21a of the operation piece 20 is formed.
Is guided by the guide protrusion 19 of the notch recess 17,
The gap 23a of the operation piece 20 is guided by the guide piece 18 of the cutout recess 17, and the operation piece 20 moves in the depth direction of the cutout recess 17. At the same time as this movement, the upward taper surface 25 of the operation piece 20
The engaging claw 14 of 13 is pushed upward, and the downward taper surface 24a pushes the engaging claw 15 of the container body 11 in the inner direction to bend it. As a result, the engagement between the engaging claws 14 and 15 is released, and the state shown in FIG. 4 is obtained. From this state, the outer lid 13 is lifted to the opened state in which the upper surface of the inner lid 12 is exposed, and then the inner lid 12 is lifted to the opened state in which the upper surface of the container body 11 is exposed. In order to bring the compact in the open state to the closed state, the outer lid 13 is pushed down to the state shown in FIG. When the upper surface of the outer lid 13 is pressed from that state, the engaging claws 14 of the outer lid 13 penetrate through the notch recesses 22 of the inner lid 12 and engage with the engaging claws 15 of the container body 11, and the compact is shown in FIG. Will be closed.

[Effect of device]

As described above, in the container lid opening / closing mechanism of the present invention, as in the prior art example, the operation piece rotates about the shaft body to push up the lid body to release the engagement between the container body and the lid body. Instead, the downward taper surface of the lower end edge of the operation piece pushes the engaging portion of the container body in the depth direction of the notch recess of the inner lid to bend it, and at the same time, the upward taper surface of the upper end edge of the operation lid engages with the outer lid. It is designed to push the joint up. Therefore, since both tapered surfaces work to release the engagement, the operation piece can be opened by only lightly pressing it, and the operation piece does not come off from the inner lid. Even when the engaging portion and the engaged portion are tightly engaged with each other, the action of the both tapered surfaces allows the lid to be opened with a comparatively light pressing force. Further, the engagement claw of the outer lid penetrates the notch recess of the operation piece attached to the inner lid and engages with the engagement claw of the container body. Therefore, in the closed state, the inner lid is fixed while covering the upper surface of the container body, so that the inner lid does not move to the outer lid side and contains the cosmetics unlike the conventional example. There is no inconvenience of flowing out to a part.
