Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention mainly relates to a cap with an elastically reversible small lid for fitting into the opening of a liquid storage container.

``Prior Art'' As a conventional cap with a small lid that flips elastically, a cap having the structure described below is widely used.

That is, grooves with upper and rear openings are vertically provided in the rear upper part of the peripheral wall of the cap body that fits into the container mouth neck, and the upper half is bent forward from the lower edge of the groove via the second hinge. or a curved leaf spring, the lower part of the leaf spring is removably fitted into the groove and erected, and the front end of the leaf spring is opened with its lower end surface in the latter half of the small lid that covers the top wall of the cap main body. The leaf spring part is fitted into the long hole through the third hinge and connected to the front edge of the vertically installed long hole, and the rear part of the top wall of the cap body and the rear part of the small lid on both sides of the leaf spring are connected to the front edge of the long hole provided vertically. The first
They are connected together via a hinge, and a stopper hanging from the back of the small lid is removably fitted into an outflow hole drilled in the top wall of the cap main body.

In this configuration, when the small lid is rotated rearward and upward with respect to the cap body around the first hinge, the leaf spring is elastically deformed and then elastically restored, and the small lid opens with respect to the cap body, and returns to this state. When the front part of the small lid was pushed forward, the leaf spring was elastically deformed and returned to its original state, and the plug of the small lid was formed to close the outflow hole in the top wall of the cap body.

``Problems to be solved by the invention'' Conventionally, this type of cap with a small lid that is elastically inverted by a so-called three-point hinge has a small lid part cut out inside the leaf spring that has the second and third hinges. The plug that hangs down from the inner surface of the cap body and closes the outflow hole on the top wall of the cap body will be installed hanging down from the part that does not have the above notch. It was necessary to provide a small portion at each front portion.

This proposal makes it possible to increase the diameter of the outflow hole on the top wall of the cap body and the plug of the small lid by eliminating the notch in the small lid of a cap with a small lid that can be elastically reversed using a three-point hinge. In addition to widening the range of uses, the cap is made easy to mold from a synthetic resin material by forming the leaf spring of the cap separately.

``Means for solving the problem'' A small lid 7 is attached to the upper rear surface of the cap body 1 which is fitted to the mouth and neck of the container body via an elastic reversing mechanism, and a small lid 7 is bored in the top wall 3 of the cap body. In a cap whose through hole 2 is opened and closed by a stopper 8 hanging from the lower surface of a small lid 7, the rear edge of the cap main body peripheral wall 4 and the rear edge of the small lid 7 are connected with two first hinges 6, 6 with an appropriate gap between them. A bent or curved leaf spring 12 with second and third hinges is attached along each outer surface of the small lid and the rear part of the cap main body which are in contact with an imaginary vertical plane passing through the gap and the center of the small lid. , the lower end of the leaf spring is fixed to the lower rear surface of the cap body 1, and the front end of the leaf spring is fixed to the upper surface of the small lid.
The second hinge 16 was provided in the leaf spring portion below the hinge 6, and the third hinge 17 was provided in the leaf spring portion in front of the first hinge 6, respectively.

"Operation" When the small lid 7 is closed and the finger hook 11 at the front of the small lid is pushed up against the cap body 1, the small lid is elastically inverted by the elasticity of the leaf spring 12 around the first hinges 6, 6. The plug 8 is connected to the through hole 2 in the top wall 3 of the cap body.
Get out of. Next, push the finger hook forward,
The small lid is elastically inverted again and the stopper 8 is fitted into the through hole.

``Embodiment'' The cap of the present invention includes a cap main body, a small lid integrally connected to the rear upper end of the outer cap main body via a first hinge, a lower part to the lower rear surface of the cap main body, and a front part to the small lid. Each consists of a fixed leaf spring.

Further, it is preferable to provide a groove on the outer surface of the peripheral wall above the fitting portion to fit the lower portion of the leaf spring. The above-mentioned through hole is formed by the nozzle hole of the nozzle 2a which stands up from the top wall.

A small lid 7 is attached to the rear edge of the top wall 3 of the cap body via a first hinge 6. Two first hinges are provided with appropriate gaps between them, and a plug 8 for closing the aforementioned through hole 2 is suspended from the lower surface or inner surface of the small lid.
Inside the stopper is a first blind hole 9 with an opening on the top surface, and a second blind hole 10 is bored in the upper surface of the small lid in front of the first blind hole 9, and a finger hook 11 is further protruded forward from the front end of the small lid in front of the second blind hole 9. I'm letting you do it. The first blind hole 9 is bored in the center of the upper surface of the small lid, and the first blind hole, the second blind hole,
The gap between the finger hook 11 and the aforementioned first hinge is located on the diameter line in the front-rear direction of the small lid, and a groove for fitting the leaf spring portion described later is provided in the small lid portion on the diameter line.

The leaf spring 12 has its upper part bent or curved forward, and is fitted into the grooves of the cap main body and the small lid, and its lower end 13 is fitted into the above-mentioned fitting part,
Also, first and second rods 14 and 15 hanging down from the front are fitted into the first and second blind holes 9 and 10. The leaf spring has a thin second hinge 16 at the bottom and a third hinge 17 at the top, the second hinge being lower than the first hinges 6, and the third hinge 17 being lower than the first hinge. It is located in the front.
