Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial application field" The present invention relates to a container with a lid plate that is elastically inverted. In the present specification, the term “container or the like” is used to include both a cap and a container.

"Prior Art" Conventionally, many containers with lid plates that are elastically inverted are known, and a typical one is a so-called three-point hinge cap or container. The cap or container includes a pair of left and right cap main bodies or container body upper ends and a rear lower end of a lid plate placed on the upper surface of the cap body or container body, the mouths of which are opened on the upper surfaces thereof. First
The ends of the inverted L-shaped elastic plate provided between the first hinges are connected to each other by a hinge, and one end of the inverted L-shaped elastic plate is connected to the rear part of the cap body or the like below the first hinge via the second hinge, and the other end of the elastic plate is the first hinge. It is connected to the upper surface of the lid plate in front of each other via the third hinge.

[Problems to be Solved by the Invention] In a conventional container with a lid plate by a so-called three-point hinge mechanism, its inverted L-shaped elastic plate is largely exposed to the upper surface of the rear half of the lid plate, which impairs the appearance. There is a drawback that the rear surface of the bent portion of the hinge becomes a sharp edge on the rear surface of the container or the like and easily protrudes, and the protruding portion impairs the feel. Further, since there are three thin-walled hinge portions, it is difficult to design the mold and the cost is increased.

Therefore, an object of the present invention is to provide a container with a lid plate that is elastically inverted and has a good appearance and feel and can be manufactured at low cost.

[Means for Solving the Problems] In order to achieve the above object, an elastically inverting container with a lid plate according to the present invention has a mouth portion 5 on the upper surface, and a concave portion 7 having an upper surface and a rear surface open at the rear upper portion of the main body. It has a container 8 or the like that has been bored and a lid plate 9 that closes the mouth, and an elastic piece 18 extends from the rear edge of the recess to the front inside the recess via a first hinge 17. The one front end is connected to the lower end of the support wall 19 that hangs from the rear edge of the lid plate into the recess via the second hinge 20, and the second hinge upper support wall portion of the support wall is located in front of the recess. The left and right parts are pivotally attached to each other, and a curved portion 18a is attached in the middle of the elastic piece 18,
By rotating the cover plate 9 around the pivotally connecting portion 21,
The elastic piece is elastically deformed and then elastically restored so that the lid plate is elastically reversible.

[Operation] For example, when the front portion of the cover plate 9 is rotated clockwise with respect to the container portion 8 around the pivot portion 21 from the state of FIG. 1, the elastic piece 18 is elastically deformed in the expanding direction and then elastically deformed. Since it is restored, the lid plate is elastically inverted to open the upper surface of the container or the like (see FIG. 4).

When the front portion of the lid plate is rotated counterclockwise from the above state, the lid plate elastically reverses and closes the upper surface of the container or the like as described above.

[Example] An example of the container of the present invention will be described below with reference to the accompanying drawings.

In FIGS. 1 and 2, 1 is a container body with a mouth / neck portion 2, and 3 is a cap attached to the mouth / neck portion 2 of the container body.

The cap 3 is provided with a peripheral wall 4 screwed onto the outer surface of the mouth / neck portion 2 of the container body so as to vertically extend from a peripheral edge of a top wall 6 having a mouth portion 5.
The top wall 6 includes a cap body 8 having a first recess 7 opened at the rear surface and an upper surface and a rear surface, and a lid plate 9 closing the opening 5.

A second recess 10 is bored in the front part of the top wall 6 of the cap body, an engaging projection 11 is provided laterally on the rear surface of the second recess 10, and a first support is provided from the intermediate part of the lower surface in the front-rear direction. The wall 12 is erected with the upper end surface of the support wall slightly protruding from the upper surface of the top wall 6. On the other hand, from the lower surface of the front portion of the cover plate 9, an elastic engagement piece 13 that engages with the lower edge of the engagement projection 11 is hung, and forward from the front edge of the cover plate 9 via a bending line 14. The rear lower surface of the extended operation piece 15 is placed on the upper end surface of the support wall 12.

Further, as shown in FIG. 3, the second support wall 16 is erected upward from the rear edge of the first recess 7, and the elastic piece 18 is inserted from the upper end of the support wall 16 through the first thin hinge 17 into the recess. The front end of the elastic piece 18 extending forward is connected to the lower end of the third support wall 19 hanging from the rear edge of the cover plate 9 into the recess via the second thin hinge 20, and at the same time, the third support wall 19 An intermediate portion in the up-down direction is pivotally attached (joined to the pin 21) to both left and right portions located in front of the recess 7. Reference numeral 22 in FIG. 3 denotes a pin fitting hole.

Then, a curved portion 18a is provided in the middle of the elastic piece 18, and the cover plate 9 is rotated around the pin 21 coupling portion, whereby the elastic piece 18 elastically deforms and then elastically restores. The cover plate 9 is formed so as to be elastically reversible. That is, as shown in FIG. 4, the pin 21 coupling portion of the second thin hinge 20 is centered on the outside of the virtual rotation locus l ₁ of the second thin hinge 20 about the first thin hinge 17. It is set so that a part of the rotation locus l ₂ is projected. Reference numeral 23 in the drawing denotes an elastic seal plate fixed to the lower surface of the cover plate 9.

Therefore, in this embodiment, when the operation piece 15 is pushed down,
The front portion of the cover plate 9 is lifted by the action of the "lever", whereby the elastic engagement piece 13 is disengaged from the lower edge of the engagement projection 11.

In addition, in the above-mentioned embodiment, each part is appropriately molded and manufactured by a synthetic resin material.

[Advantages of the Invention] As described above, according to the present invention, although the elastically reversing lid plate is integrally formed with the container or the like, only two thin hinge portions are required, which makes it possible to design the mold. It becomes easier and cost can be reduced. In addition, since the lid plate is not formed with a cut or the like as in the conventional example, it is possible to close the large-diameter opening portion and is good in appearance. Furthermore, since there is no protruding part that becomes an edge, it feels good.
