Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention relates to a cap used for cream bottles and the like.

"Problems to be solved by conventional techniques and devices" It is common to use a cream bottle that contains cream, etc. with a large opening and a screw lid to close this opening. Each time, loosen the screw lid back and open it,
There is also the trouble of tightening and closing the lid.

The present invention is intended to obtain a convenient cap that can be opened and closed with one touch.

[Means for Solving the Problems] The cap of the present invention is a piece in which a rear end is pivotally attached to the opening of the peripheral wall member 1 for attachment and a front end is engaged with the peripheral wall member 1 for attachment which is attached to the bottle 4 mouth portion. An openable canopy 2 for opening and sealing, and a ring shape arranged so as to surround the outer surface of the canopy, are pivotally attached to the canopy 2 on both left and right sides, and have the canopy 2 on the front rear surface. The lever 5 located at the engaging portion is pivotally attached, and when the front portion is pushed downward, the lever 5 is rotated to release the engagement of the canopy 2 and open the lid. I am trying.

[Operation] In the above cap, the mounting peripheral wall member 1 is normally screwed to the mouth of the bottle body 4, and the one-sided canopy 2 engages the front end of the front wall of the peripheral wall member 1 with the front end thereof. The opening of the member 1 is unsealed and the lever 5 of the operating ring 3 rests on the shoulder 6 at the front of the peripheral wall member 1.

Here, in order to open the cap, the front portion of the operation ring 3 may be pushed downward. Then, since the lever 5 rotates counterclockwise in FIG. 1 with the point on the shoulder 6 as a fulcrum, the engaging portion on the front rear surface of the canopy 2 is pushed up and the engagement is released by this pushing up. Therefore, the canopy 2 is opened. Therefore, it suffices to open the combined body of the rear operation ring 3 and the canopy 2 rearward with the rear pivot portion as a fulcrum. When the lid is closed, conversely, the combined body of the operation ring 3 and the canopy 2 may be pushed into the opening of the peripheral wall member 1.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.
The cap of the present invention comprises a mounting peripheral wall member 1, a canopy 2 and an operating ring 3.

The mounting peripheral wall member 1 has a shape in which a mouth portion 8 whose diameter is reduced from the upper end of the screw cylinder 7 via a shoulder portion 6 is provided at a position slightly closer to the rear portion, and thus the shoulder portion 6 has a shape in which the rear portion is steeply inclined. Shoulder 6
A groove 9 for a hinge is formed in a concave shape on the rear side, a seat 10 is raised on the upper surface on the front side, and an engaging projection 11 is protruded on the upper front surface of the mouth section 8. It is attached by screwing to the outer surface of the mouth. 12 is a ring stopper.

The canopy 2 has a circular basin shape somewhat wider than the mouth portion 8. The canopy 2 projects a hinge boss 13 fitted into the hinge groove portion 9 from the mouth portion side, and engages with the engaging protrusion 11 on the front rear surface. An engaging member 15 having an engaging protrusion 14 that forms a stopper plate together is provided vertically, and pins 16 and 16 are provided so as to project from both left and right outer surfaces,
The hinge 13 is pivotally attached to the hinge groove portion 9 by a hinge pin 17 so as to be capable of opening one side. A spring with a beard on this hinge
18 is provided, and this spring 18 constantly biases the canopy 2 in the opening direction.

A packing 19 is adhered to the back surface of the canopy 2 with a double-sided tape 20 to keep the canopy 2 in a hermetically closed state.

The operation ring 3 has a ring-like shape with the gutter upside down.
Is formed so that the holes 21 and 21 are fitted into the pins 16 and 16 so as not to come out, and the canopy 2 is connected to the periphery of the canopy 2, and a V-shaped hinge 22 is provided inside the front face portion. A lever 5 having a character shape is integrally provided. The corner of the lower end of the lever 5 rides on the seat 10 and serves as a fulcrum, and the free end of the lever 5 is close to the lower end surface of the engaging member 15 from below.

Therefore, in this embodiment, when the front portion of the operating ring 3 is pushed downward, the lever 5 rotates counterclockwise in FIG. 1 with the corner portion in contact with the seat 10 as a fulcrum. Then, the free end that pops up pushes the coupling member 15 upward to unlock the stopper plate, so that the canopy 2 is opened. Therefore, it suffices to open the combined body of the canopy 2 and the operation ring 3 upward and rearward using the hinge of the rear part as a fulcrum, and the lid can be opened with one touch.

 Each of the above parts is molded and manufactured from a synthetic resin material.

[Advantage of the Invention] As described above, in the present invention, the canopy 2 of the cap is formed as a separate single-sided member, and the canopy 2 is opened via the lever 5 by pushing up the operation ring 3 arranged around the canopy 2. Since it is configured to be opened, it is extremely convenient to open and close with one touch. Further, the outer shape is substantially the same as that of the conventional screw cap, and the designability is not impaired. Rather, there is an advantage that the designability can be improved by color-coding each part.
