Description

[Detailed description of the invention] "Industrial application field" This invention relates to a cap for a container that stores shampoo, rinse, etc.

``Prior art'' For example, as disclosed in Japanese Patent Publication No. 50-34471, a cap is made up of a cap body that fits into the mouth of a container, and a lid member attached to the cap body, and the front and back diameters of the upper surface of the top wall of the cap body are In this direction, a shallow groove is provided in the front half and a deep groove is provided in the rear half, and a discharge hole is bored in the front half of the groove, and the lid member extends from the rear end of the deep groove of the cap body to the first elastic plate portion. standing up, and protruding the second elastic plate portion forward from the upper end of the first elastic plate portion via the first thin hinge, and further protruding the third elastic plate portion forward from the front end of the plate portion via the second thin hinge; The third
The left and right sides of the rear portion of the middle portion of the elastic plate portion are pivotally connected to the groove wall portion at the boundary between the deep groove portion and the shallow groove portion, and the third elastic plate portion in front of the pivot portion is used to open the aforementioned drawing hole. When a lid plate that opens and closes is formed and the front end of the lid plate is pushed up, the third elastic plate portion rotates around the pivot portion by elastic reversal against the elasticity of the first and second elastic plate portions. A cap is known in which the lid plate is raised by moving the cap.

``Problem to be solved by the invention'' The conventional cap mentioned above has the convenience of being able to open and close by elastically reversing the lid plate, but the opening and closing of the lid plate utilizes the principle of levers, and is pivoted from the front end of the lid plate. By making the length from the pivot point longer than the length from the pivot point to the rear end of the cover plate, rotation becomes easier. In the above-mentioned conventional cap, the diameter of the container neck and the diameter of the cap body are approximately equal, and the length of the lid plate is made shorter than the equal diameter. Therefore, when the diameter of the container neck becomes smaller, As the diameter becomes smaller, the length from the front end of the lid plate to the pivot point also becomes shorter, and therefore, when the diameter of the cap becomes smaller, the practicality of the conventional cap is lost. In addition, the elastic deformation for reversing the elasticity of the cover plate is mainly performed only by the first and second elastic plate parts mentioned above, and these two elastic plates often do not perform very well due to their relationship with the cover plate. However, the first and second elastic plates are likely to be strained, and therefore the lid member often has to be molded from a high quality synthetic resin material.

The present invention eliminates the above drawbacks, allows the length of the lid plate to be longer than the diameter of the mouth and neck of the container body, and prevents strain on the first and second elastic plates. This is provided so that the cap can be easily molded.

"Problem to be solved by the invention" Cap part 6 to be fitted into the mouth and neck part 5 of the container body 4
A cap main body 1 having a spouting hole 3 bored in the top wall 2 of the cap, and extending the left and right side walls of the peripheral wall of the cap part parallel to the rear and connecting the rear ends of these both sides with a rear wall 1a. , the first one from the upper end of the rear wall 1a.
The first elastic plate 7 is protruded downward and forward via the thin hinge 11, and the second elastic plate 8 is erected from the lower end of the first elastic plate via the second thin hinge 12, and the upper part of the second elastic plate is erected. A plug 14 is attached to the front surface, and a support plate 9 is suspended from the front part of the second elastic plate below the plug,
It consists of a swinging lid plate 10 whose lower end of the support plate is rotatably pivotally connected to the cap main body portion between the rear surface of the cap portion 6 and the lower end of the second elastic plate, and the pivotally attached 13
When the second elastic plate 8 is tilted forward using the portion as a fulcrum, the stopper 14 closes the spout hole 3 and the second elastic plate 8 and the first elastic plate 7 are formed to open approximately 180°.

"Operation" From the state shown in FIGS. 1 and 2, the swinging lid plate 10
When the upper end is pushed forward, the swinging lid plate will move to the pivot point 1.
3 as a fulcrum, and due to this rotation, the lower end of the second elastic plate 8 moves from the pivot portion 13 to the second thin hinge 1
2, the lower end of the first elastic plate 7
Since it is about to move through an arc A whose radius is the distance from the thin hinge 11 to the second thin hinge 12, the dead center is the inclined position shown by the two-dot chain line in FIG. 15, the swinging cover plate 10 resists the elasticity of both elastic plates, and after passing through the dead center, the swinging cover plate 10
falls down, and at this time the stopper 14 closes the spout hole 3.
By pushing up the front end of the swinging cover plate from the collapsed state, the cover plate passes the dead center again, and then moves and stands up by elastic reversal to the position shown in the figure.

``Example'' 4 is a container body, and a neck portion 5 is erected from the upper end of the body via the shoulder portion. The shoulders are narrow at the front of the container body and on both left and right sides, and wide at the rear, so that the neck and mouth stand up from the front of the body. The body of the container body is preferably formed to be elastically compressible.

The cap consists of a cap body 11 and a swinging lid plate 10.
to form.

The cap body 11 has a cap portion 6 that is screwed into the mouth and neck portion 5. Top wall 2 of the cap part
has a pouring hole 3, and a peripheral wall hangs down from the periphery of the top wall thereof. Right and left side walls extend rearward in parallel from both the left and right sides of the peripheral wall, and the rear ends of these side walls are connected by a rear wall 1a. Further, the support plate 2a may protrude rearward from the rear end of the top wall 2. A finger rest recess 16 is provided in the front part of the top wall, and 17 is a reinforcing plate for the support plate.

The swinging lid plate 10 has a first elastic plate 7 protruding downward and forward from the upper end of the rear wall 1a via a first thin hinge 11, and a first elastic plate 7 protruding downward and forward from the lower end of the first elastic plate via a second thin hinge 12. to stand up the second elastic plate 8.
Further, a plug 14 is attached to the upper front surface of the second elastic plate,
The support plate 9 is suspended diagonally downward and forward from the front part of the second elastic plate below the plug, and the lower end of the support plate is rotated to the cap main body part between the rear surface of the cap part 6 and the lower end of the second elastic plate 8. Pivot as possible. In the illustrated example, pins protrude from both left and right sides of the lower end of the support plate, and these pins are fitted into bearings that protrude rearward from both left and right ends of the rear end of the support plate 2a described above, but if no support plate is provided, , the above-mentioned pins are pivoted 1 to the inner surfaces of both side walls 1b and 1b extending from the left and right sides of the cap peripheral wall to the rear.
3.

The first and second elastic plates and the support plate 9 are as follows:
When the swinging lid plate 10 is folded down, the plug 14 closes the spout hole 3, and the first and second elastic plates 7, 8 are formed to open approximately 180°.

"Effect of the invention" The present invention has the above-described structure, and the lower end of the support plate 9 is rotatably attached 13 to the cap main body portion between the rear surface of the cap part 6 and the lower end of the second elastic plate 8. Since the attachment portion is the center of rotation of the swinging lid plate 10, the length of the swinging lid plate can be made larger than the diameter of the container neck 5 and the cap portion 6 fitted to the neck. Therefore, it is possible to easily push up and push down for rotating the swinging lid plate, and the rear wall 1
A support plate 9 is suspended from the upper front surface of the second elastic plate 8 which stands up from the lower end of the first elastic plate 7 hanging from the upper end via the second thin hinge 12, and the lower end of the support plate is connected to the rear surface of the cap part and the second elastic plate. Since the second elastic plate 8 is pivotally attached to the lower end of the plate, the length of the second elastic plate 8 can be increased compared to the conventional one, and thus the elastic deformation of the first and second elastic plates can be facilitated. I can do it.

Furthermore, in this case, the lower end of the support plate 9 is formed by being pivoted to the cap main body portion between the rear surface of the cap part and the lower end of the second elastic plate 8, so when forming the cap, the two-dot chain line in Fig. 1 is formed. As shown, the swinging lid plate 10
is integrally molded from a synthetic resin material in such a manner that it protrudes rearward from the upper end of the rear wall 1a, and after the molding, the support plate 9 is attached.
The lower end can be pivoted as described above, and therefore the cap according to the present invention can be easily molded. The present applicant previously filed Utility Application No. 60-42961, but since the device connects the lower end of the support plate and the rear end of the support plate via the third thin hinge, it does not swing as in the above-mentioned proposal. It is not possible to integrally mold the cap with the lid plate tilted backward from the upper end of the rear wall.
