JPH063804Y2 - Distributing mirror hinge cap - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial Application" The present invention relates to a distributed mirror hinge cap.

"Prior art" Caps that are installed in the bottles of bottles must be easy to open and close, and the closure of the container must be reliably achieved when closed, but the cap is lost when opened. In order to prevent this from happening, a lid has been integrally provided in a separable manner through a hinge with an inner plug provided with a spout that is assembled to the mouth tube.

However, if the inner stopper and the lid are simply integrated via the hinge portion, the lid may float up from the upper end of the inner stopper when closed, and the closure may not be reliably achieved. There is a drawback in that the lid rotates to obstruct the pouring when pouring the stored liquid while opening the body and tilting the bottle container. Therefore, in order to eliminate such defects,
For example, as disclosed in Japanese Utility Model Laid-Open No. 58-33442, not only is a pair of hinge pieces projecting between the inner plug and the lid, but also a bent shape is formed between the pair of hinge pieces. A so-called mirror hinge cap has been developed in which a highly flexible connecting piece is arranged.

This is a self-holding type that tries to maintain the closed posture or open posture of the lid body by the returning action to the bending posture before and after the dead center formed by the hinge piece of the connecting piece, and is extremely effective. Produce an effect.

However, in this mirror hinge cap, since the inner plug and the lid are integrally formed, the inner plug and the lid have the same material and the same color.

In this way, if the inside plug and the lid are of the same color, there is no whiteness on the upper surface of the appearance, and since the inside plug and the lid cannot be recognized at a glance, it takes time to distinguish and operate only the lid.

Functionally, the inner plug is preferably made of synthetic resin such as polyethylene, which has a suitable sheath property for the bottle mouth, whereas the lid having the hinge and the connecting piece has repeated bending and bending elasticity. Since a synthetic resin such as strong polypropylene is preferable, a separate type, that is, a distribution type is proposed in Japanese Utility Model Publication No. 57-52452.

"Problems to be solved by the invention" In the distribution type mirror hinge cap described in the prior art, the sealing structure for the bottle mouth is such that the inner plug is only in contact with the inner peripheral edge of the bottle mouth and the two surfaces of the upper end. , The three-sided contact pressure is sealed by receiving the support of the cylinder part on the lid side that is fitted to the outer periphery of the other side of the bottle mouth while pressing the contacting portion to the upper end of the pin mouth. In comparison with a crotch type seal, which is the most ideal seal for the above, the problem is that the concern about seal leakage due to shock during transportation cannot be eliminated.

The present invention has been made in view of the above problems of the prior art, and the purpose thereof is to make a saddle-shaped one-piece body which is the most ideal seal for the three faces of the bottle mouth due to the inner stopper. It is an object of the present invention to provide a distribution type mirror hinge cap in which a separately constructed lid body is assembled without any hindrance while having a crotch type.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the distribution-type mirror hinge cuff according to the present invention has an outer cylinder and an inner hanging piece, and is attached to a bottle mouth like a saddle. Between the outer cylinder and the inner cylinder at the rear end portion of the top wall of the topped triple cylinder having a cylinder, an insertion recess is formed in the up-down direction, and a spout cylinder is formed at the center of the top wall. At the rear end of the standing inner plug, and the lower end of the cylindrical wall of the topped cylindrical member capped at the upper end of the inner plug, a locking tongue piece fitted and locked in the insertion recess, and a pair of hinge pieces are provided. Of the U-shaped connecting piece that is elastically deformable and is located inside the pair of hinge pieces by locking the lower end of the locking tongue piece to the lower end of the insertion recess from below. A lid body in which the upper end is connected to the top plate of the toped tubular body via a thin portion and the lower end is connected to the outer surface of the locking tongue piece via a thin portion. It consists of

[Operation] In the cap of the present invention, the inner plug provides the most ideal seal when the integrally molded saddle portion is fitted on the pin mouth.

Further, since the assembly portion of the lid body with respect to the inner stopper is secured outside the saddle portion, that is, outside the bottle mouth, the seal of the inner stopper is not disturbed at all.

[Example] An example will be described with reference to Figs. 1 and 2.

The inner stopper 1 is a capped triple cylinder having an outer cylinder 3 and a middle cylinder 4 having a middle hanging piece 23 and attached to a bottle mouth like a saddle.
The inner cylinder 4 is attached to the bottle mouth, and an insertion recess 6 is formed in the up-down direction between the outer cylinder 3 and the inner cylinder 4 at the rear end of the top wall 2 to form an opening. This is a configuration in which the spout cylinder 9 is erected in the central portion.

The height of the inner cylinder 4 is smaller than that of the outer cylinder 3, and the inner peripheral surface of the inner cylinder 4 is a screw thread that is screwed into a screw thread provided around the outer peripheral surface of a predetermined bin opening (not shown). 5 are installed around.

A notch 7 is provided at the upper end of the rear end of the outer cylinder 3 facing the insertion recess 6.

The cutout portion 7 has an inverted convex shape in which the central portion of the relatively wide cutout is further deeply cut, and a step portion 8 facing upward is formed.

The lid body 10 is a topped cylinder body, and has a locking tongue piece 13 fitted and locked in the insertion recess 6 at the rear end of the lower end of the cylindrical wall 12 thereof.
It is integrally provided via a pair of hinge pieces 17, and the lower end of the locking tongue piece 13 is locked to the lower end of the insertion recess 6 from below.

Further, a U-shaped connecting piece 18 capable of elastic deformation is positioned inside the pair of hinge pieces 17, and the upper end of the connecting piece 18 is connected to the above-mentioned topped cylindrical body through a thin portion 19. The locking tongue piece 13 is connected to the top plate 11 and has the lower end through the thin portion 20.
Are connected to the outer surface of.

As a result, the connecting piece 18 has a dead point at the upright posture point during the swing of the lid 10. Before and after the most extended posture point, the restoring force to the U-shape is released and the lid is closed and the lid is held.

The locking tongue 13 is provided with a locking strip 14 on the inner surface of the lower end in the shape of a horizontal strip, and when the locking tongue 13 is fitted into the insertion recess 6, the locking strip 14 has the above-described inner cylinder 4 Lock from the bottom to the bottom.

A thick portion 15 is formed on both sides of the upper end of the locking tongue 13 so as to project outward, and the hinge piece 17 is projectingly provided on the thick portion 15, and A connecting piece 16 is provided so as to project from the central portion of the outer surface of the tongue piece 13.

When the locking tongue piece 13 is fitted into the insertion recess 6, the thick portion 15
The connection piece 16 is mounted on the step portion 8 of the cutout portion 7, and the connection piece 16 is mounted on the lowermost end portion of the cutout portion 7.

Then, from the lower end of the cylindrical wall 12 at the rear end of the lid 10 to the top plate 11
A cutout 22 is formed in the central portion,
The upper end of the connecting piece 18 is connected to the upper end of the cutout portion 22 through the first thin wall portion 19, and the lower end of the connecting piece 18 is connected through the second thin wall portion 20 to the locking tongue piece 13 described above. Is connected to the connecting piece 16 and the connecting piece 18 is located inside the cutout portion 22 when the lid 10 is closed.

In the illustrated embodiment, the lid 10 is dome-shaped and has a top plate.
