Description

[Detailed description of the invention] "Field of industrial application" This invention relates to a cap with an elastically reversible lid plate.

``Prior Art'' As disclosed in, for example, Japanese Utility Model Application Publication No. 53-154152, a cap with a so-called three-point hinge and an elastically reversible lid plate has become widespread. The cap usually has a lid plate that opens and closes the top surface of the cap body via two first thin hinges on the left and right sides, at the rear upper end of the cap body where the peripheral wall for fitting the container body mouth neck hangs from the outer periphery of the top plate with the mouth part. and the above first
An L-shaped elastic plate is erected from the lower circumferential wall portion between the hinges via the second hinge, and the other end of the elastic plate is connected to the first
It is attached to the upper surface of the intermediate portion of the lid plate in front of the hinge area via a third hinge.

``Problem to be solved by the invention'' Since the conventional three-point hinged cap described above connects the cap body and the lid directly through the first hinge, an L-shaped elastic plate is used to elastically invert the lid. It has to be provided between the narrow cap body and the lid body, which makes its formation cumbersome, complicates the structure, and increases costs.

The present invention proposes a cap with a lid plate that is simple in structure and easy to mold by connecting the cap body and the lid body through an elastic reversing mechanism instead of directly connecting them as described above.

"Means for Solving the Problem" A recess 6 with an open top and rear surface is formed at the rear of a cap main body 2 that is removably fitted into the opening of a container main body, and a base plate from which a bottom wall 6a of the recess stands upright. 7 First and second elastic arms 8, 9 from the upper end to the front, rear, upper and outer sides.
protrudes with a gap between the first elastic arm 8 and the front wall surface of the recess, and connects the first and second elastic arms from the upper ends of both arms via the first and second hinges 10 and 11. 1st and 2nd along 8 and 9
The arcuate pieces 12 and 13 are protruded downward and inward, and the lower ends of the first and second arcuate pieces are connected via the third hinge 14, and from the upper end of the second arcuate piece 13, the main body top wall 2a of the cap is connected. It is characterized by having a protruding lid plate 4 that closes a spout 3 that opens on the top surface.

"Function" When the front end of the cover plate 4 is pushed upward and backward from the state shown in FIG. Push up the third hinge 14.

The distance between the first and second hinges 10, 11 is
Since it is smaller than the sum of the distance between the hinge 10 and the third hinge 14 and the distance between the second hinge 10 and the third hinge 14, the first and second arcuate pieces 1
As the third hinge 14 portion that connects the first and second hinges 10 and 13 rises, the first and second elastic arms 8 and 9 are elastically deformed and the distance between the first and second hinges 10 and 11 is widened. , when the third hinge 14 is positioned on the straight line connecting the second hinges, and the third hinge 14 moves upward on the straight line, the first and second elastic arms 8 and 9 elastically restore the second hinge.
As shown in the figure, the cover plate 4 stands up due to elastic reversal. Also when the lid plate is closed, the third hinge 14 is elastically reversed when moved downward in the above-mentioned straight line.

``Example'' 1 is a container body, a cap body 2 is fitted to the upper end of the container body, and a spout hole 3 communicating with the inside of the mouth neck of the container body is bored in the front part of the top wall 2a. . A recess 6 with an open top and rear surface is bored in the rear part of the cap body. As shown in the illustrated example, the left and right sides of the recess may also be opened.

A base plate 7 stands up from the bottom wall 6a of the recess 6, and first and second arms 8, 9 project from the upper end of the base plate 7 in an arc shape forward, backward, upward, and outward. Between the first arm 8 on the front side and the front wall surface of the recess 6, a first
A gap is provided as an allowance for arm deformation.

From the upper ends of both arms are the first and second hinges 1.
0, 11 and the first and second elastic arms 8,

Connect with. Further, from the upper end of the second arcuate piece 13, a lid plate 4 with a stopper 5 for closing the spout hole 3 mentioned above projects. Each hinge V-shaped groove 10a, 11a, 14 mentioned above
By providing a, a thin hinge can be obtained.

Base plate 7, first and second elastic arms 8, 9, first,
The second circular arc pieces 12, 13, the cover plate 4, etc. form an elastic reversing mechanism, and may be integrally molded with the cap body 2 from a synthetic resin material, or the lower surface of the base plate 7 may be formed as a separate member. It may also be glued.

``Effect of the invention'' The present invention has the above-described structure, and instead of directly connecting the cap body and the lid body as in the conventional example described above, the base plate 7 and the first and second elastic arms 8, 9 are connected to each other. Since the cap body and the lid plate are connected through the elastic reversing mechanism formed by the first and second arcuate pieces 12 and 13, the installation space for the elastic reversing mechanism is narrowed, which increases the complexity of the structure and increases costs. Since a gap is provided between the first elastic arm 8 and the front wall surface of the recess 6, the elastic deformation of the first elastic arm 8 will not be a hindrance. Furthermore, since the cap body and the lid are connected through the elastic reversing mechanism, the lid does not wobble when the lid is opened.
