Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention relates to a thin container with a lid.

"Prior Art" As a container of this type, as seen in a compact cosmetic container, the rear edge of the main body of the container and the rear edge of the lid are pivotally attached to each other, and a torsion spring is incorporated in this pivotal portion to attach the lid. There is one that always urges in the opening direction.

[Problems to be solved by the invention] However, in the conventional container as described above, there is a problem that the cost is increased due to an increase in the number of parts due to a torsion spring and a complicated structure of the lid holding means for the lid. There was a point.

Then, this invention aims at providing the container with a lid which can achieve cost reduction by adoption of an elastic inversion mechanism.

[Means for Solving the Problems] In order to achieve the above object, the container with a lid of the present invention has a recess 4 for accommodating articles in the upper surface thereof, and at least the circumference from the front end surface to one of the left and right side surfaces. A plate-like base body 1 having a curved surface 6 formed in the front-rear direction, a rear end portion of a top plate 2a closing the upper surface of the plate-like base body, and the rear end portion of the plate-like base body are provided with a first bending portion 9 therebetween. A lid spring 2 connected between the plate-shaped base body side surface and the lid front portion, and the plate spring is provided between the plate-shaped base body side surface intermediate portion and the second bending portion. 5 and projecting along the curved surface to the front end face of the plate-shaped base body, the tip end of the leaf spring is connected to the rod-shaped connecting portion 8 hung from the front end portion of the top plate via the third bending portion 7, and By forcibly rotating the base body from the state to the outside of the curved surface with the first bending portion 9 as the center, the leaf spring is moved. Sex reversed and the lid towards plate substrate rear side, characterized in that is formed movably.

[Operation] For example, when the lid 2 is forcibly rotated outward from the curved surface 6 around the first bending portion 9 from the state shown in FIG. 1, the leaf spring 3 is also bent and rotated around the second bending portion 5. The locus of movement of the front end of the lid ₁ and the locus of virtual rotation of the tip of the leaf spring l ₂
When the lid rotates to the point P where and intersect, the leaf spring elastically reverses (see FIG. 3). As a result, the lid moves rearward of the plate-shaped substrate to open the upper surface of the plate-shaped substrate and is positioned at the position.

On the contrary, when the lid is closed, the lid body may be forcedly rotated to the upper side of the plate-shaped substrate.

[Embodiment] An embodiment of the container with a lid of the present invention will be described below with reference to the accompanying drawings.

As shown in FIG. 1 to FIG. 3, in this embodiment, the upper surface of the plate-like base 1 having an oval shape elongated in the front-rear direction is provided with two lids 2 and 2 which are symmetrically arranged. An example is shown in which the two leaf springs 3 and 3 that are symmetrical are elastically reversed to open and close. Of course, it is also possible to open and close the upper surface of the plate-shaped substrate 1 with one lid 2 by elastically reversing one plate spring 3.

The plate-shaped substrate 1 is made of synthetic resin and has an article storage recess 4 ...

Further, the leaf springs 3 are projected from the middle portions of the left and right side surfaces of the plate-shaped base 1 through the thin bent portions 5 and 5 along the curved surfaces 6 and 6 of the plate-shaped base 1 to the front end face of the base. At the same time, strips 8 and 8 as rod-shaped connecting portions from the tips of the leaf springs 3 and 3 are provided along the outer surface of the leaf spring 3 and the side surface of the plate-shaped substrate 1 through the thin bent portions 7 and 7. The strip plates 8 and 8 are extended so as to be folded back to the rear end face, and the front ends of these strip plates 8 and 8 are connected to the rear end face of the plate-shaped substrate 1 through thin bending portions 9 and 9.

An intermediate portion of the strip plate 8 is formed as a ring-shaped portion 10 which is long in the front-rear direction.

Further, on the upper end surfaces of both the strip plates 8 and 8, semi-elliptical lids 2 and 2 for closing the upper surface of the plate-shaped base body 1 are fixedly mounted via connecting members 11 and 11.

As shown in FIG. 4, the connector 11 has a pair of front and rear elastic engagements penetrating a long hole 12 formed in one side of the lid top plate 2a and the ring-shaped portion 10 corresponding thereto. Boards 13 and 13, 14
It is hung from the bottom surface.

The lid 2 and the band plate 8 may be integrated by bonding or the like without using the connecting tool 11. Further, 2b in the figure indicates a cover side wall of the lid.

Then, by forcibly rotating the lid body 2 outward of the curved surface 6 around the bending portion 9, the leaf spring 3 is elastically inverted and the lid body 2 can be moved to the rear side of the plate-shaped substrate 1. The length and the like of the leaf spring 3 are set.

[Advantages of the Invention] As described above, according to the present invention, the upper surface of the plate-shaped substrate can be opened and closed by horizontally rotating the lid using the elastically reversing plate spring. As described above, it is not necessary to use a torsion spring or a lid holding means, and a simple structure and a simple synthetic resin material can be easily manufactured, and a large cost reduction can be achieved.
