Description

[Detailed description of the invention] [Industrial application field] This invention relates to caps. More specifically, the present invention relates to a cap used for a shaker container or a shaker bottle.

However, there is no problem in using it for other general bottles, containers, etc.

[Conventional technology]

A conventional example of this kind of cap is
A cap as shown in Publication No. 34595 has been proposed.

This cap is as shown in FIGS. 11 and 12, and in FIG.
By engaging and attaching the engaging plate part d of the rotating plate part c to the outer end b of the rotary plate part c, elasticity can be achieved without using a metal spring.

Note that e is the drawing hole, f is the protrusion, and the rotating plate c is indicated by the arrow.
It rotates in the Af direction, thereby making it possible to unclog the dispense hole e.

[The problem that the idea attempts to solve]

However, the conventional cap described above has the following drawbacks.

The reason is that the structure for imparting elasticity to the rotary plate c is complicated and manufacturing is troublesome.

Its complexity is that, as shown in the figure, the outer end b and the engagement plate part d are bent downward, and both b and d are engaged at the lower end g as shown in the figure. It has an extremely complex structure. For this reason, manufacturing is extremely complicated.

This invention was made to solve these problems, and its purpose is to provide a simpler structure than the conventional cap described above, and to be able to provide a spring action to the lid without using a metal spring. Therefore, it is an object to provide a cap that is easier to manufacture.

[Means for solving problems]

To describe this invention which achieves the above object, it consists of a cap base 3 formed by providing a top wall 2 at one end of a cylindrical wall 1; on one side of the top wall 2;
A through hole 4 formed through the top wall 2; A fixing member 7 made of synthetic resin fixedly provided on the upper surface of the other end of the top wall 2; From approximately the center of the fixing member 7,
A protrusion 5 that is integrally provided and protrudes toward the one end of the top wall 2; a protrusion 5 that is located correspondingly on one side of the top wall 2 and has an end that faces the other side and whose upper portion extends from the protrusion; A lid 9 integrally connected to the end of the portion 5; an upper surface 9a of the lid 9 and an upper surface 7 of the fixing member 7;
A step 16 is formed between the lid 9 and the upper surface 9a of the lid 9 to be higher than the upper surface 9a; a cap consisting of legs 11 provided in the lid 9 so as to protrude from both sides of the projection 5.

[Effect]

Put your finger on the tip of the lid 9 and rotate it upward and toward the other side of the top wall 2 to open it. Then, the lid 9 rotates around the connecting portion 8 against the elasticity of the protruding portion 5 caused by the step 16, and rises up on the top wall 2 by the leg portions 11. . In this case, the protrusion 5 is elastically deformed. In this way, the lid 9 is opened. In this case, a point occurs during the rotation of the lid 9, and when the lid 9 passes the point, it becomes difficult to return and the opening is completed.

Next, in order to close this lid 9, when the lid 9 is biased in the opposite direction to the above-mentioned point, the elastic deformation of the protruding portion 5 returns, and the lid 9 is removed from the lid 9 with the finger. Even if it is released, it automatically rotates to reach one side of the top wall 2 where the through hole 4 is formed and close it.

〔Example〕

In FIGS. 1 and 2, 1 is a cylinder wall;
It is made of synthetic resin, and has a top wall 2 formed at one end thereof, and a base body 3 of the cap. 4
is a through hole formed on one side of the top wall 2 through the top wall 2, and a plurality of through holes are formed. Next 5
3 is a protruding part formed to protrude from approximately the center of a plate-shaped fixing member 7 made of synthetic resin, and the upper part of the lid 9 is integrally connected to the protruding part 5 as shown in FIG. It is provided. Further, in the lid 9, leg portions 11 are provided on both sides of the protruding portion 5. As shown in FIG. 4, the fixing member 7 is bent from the protrusion 5 and fixed to the other side of the top wall 2. Note that this fixation is performed by fusion, adhesion, and various other methods.

Reference numeral 10 indicates an imaginary line extending from the connecting portion 8, and the leg portion 11 is formed from a portion of this imaginary line 10 toward the fixing member 7.

Furthermore, although both the lid 9 and the fixing member 7 are made of polypropylene as an example, they may be made of other synthetic resins. As shown in FIG. 4, the fixing member 7 is bent from the protrusion 5, so that the upper surface 7a of the fixing member 7 is bent from the upper surface 9a of the lid 9.
A step 16 is formed against the surface. Note that the lid 9
As shown in FIG. 10, a projection 13 that enters and exits the through hole 4 may be provided. This allows the through hole 4
You can clean the inside.

The cap of this invention is manufactured as shown in FIGS. 3 and 4, for example. That is, in FIG. 3, the lower surface of the fixing member 7 is pressed from above and comes into contact with the top wall 2, and is fixed 6 by an adhesive (not shown) applied to the lower surface or by welding, as shown in FIG. 4. 5 indicates a protrusion that is not fixed.

Further, in FIG. 7, reference numeral 14 denotes a thread, which is adapted to be attached to a threaded groove in a bottle mouth, etc. (not shown). However, this portion may be formed to engage rather than screw together. Further, in FIG. 1, reference numeral 15 is a recess, which makes it easy to put a finger on the lid 9. In addition, as shown in FIGS. 5 and 8, the leg portion 1
If the lower surface 11a of 1 is formed perpendicular to the lid 9, the lid 9
can be stopped in a vertical position.

[Effect of idea]

This device is configured as described above, the fixing member 7 is fixed 6 to the other side of the top wall 2, and the fixing member 7 is fixed to the other side of the top wall 2.
A protrusion 5 protruding from the top of the lid 9 is connected 8 to the top of the end of the lid 9, and is connected to the top surface 9a of the lid 9 and the fixing member 7.
By forming a step 1 between the upper surfaces 7a in which the upper surface 9a of the lid 9 is higher, the cap has an extremely simple structure instead of the complicated structure of the conventional cap, and uses a metal spring. It can have the function of a spring without having to do so. Therefore, it is possible to provide a cap that is extremely easy to manufacture and has a spring function for opening and closing the lid.
