Abstract

PROBLEM TO BE SOLVED: To provide a cap which is not removed by a force working from the outside. SOLUTION: For the present cap, an inner cap 4 for fixing to the mouth of a container is fitted to the inside of an outer cap 3. As the outer cap 3 is pressed toward the inside, fixation is made with a projected part 7 of the outer cap engaged with an indent of the inner cap 4 and an indent of the outer cap 4 engaged with a projected part 9 of the inner cap 4. The projected part 7 of the outer cap projects at an angle of 90 deg. in the direction of engagement while projecting diagonally in the direction of disengagement. Therefore, even though the indent of the inner cap 4 is slightly engaged with the projected part 7 of the outer cap 3 while being unfixed, a force applied to the outer cap 3 is not transmitted to the inner cap because of slippage and thereby, the inner cap 4 is not detached.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a container cap.

[0002]

2. Description of the Related Art A conventional container cap is fixed to the mouth of a container by a single cap. Therefore, after the cap is fixed to the mouth of the container, it is necessary to stop the cap and the container with a tape or the like in order to prevent the cap from being detached by an external force.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to prevent a cap from being detached by an external force.

[0004]

Means for Solving the Problems The present invention relates to a container cap in which an inner cap for fixing to a mouth of a container is fitted inside an outer cap.

[0005]

According to the container cap of the present invention, since the cap is composed of the outer cap and the inner cap fitted to the outer cap, it is possible to prevent the cap from being detached from the container by an external force. it can.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS For fixing the container cap of the present invention to a container, a usual fixing means is used, but it is particularly preferable to use screwing.

In the container cap of the present invention, the outer cap and the inner cap are not usually fixed, but when the outer cap is pressed or pulled when the cap is fixed to the container, the inner cap is moved to the outer cap. The inner cap is preferably fixed to the outer cap when the outer cap is pressed. By fixing the outer cap and the inner cap, the inner cap can be fixed to the mouth of the container by screwing by rotating the outer cap. When the cap is detached from the mouth of the container, the outer cap is pressed and rotated.

Although the inner cap may be fitted to the outer cap by any means, it is preferable that the inner cap is fitted to the outer cap by a rib provided on the outer cap. The ribs are preferably provided in a linear or dotted shape along the end of the outer cap.

In fixing the outer cap and the inner cap, it is preferable that the outer cap and the inner cap are fixed by the concave or convex portion of the outer cap and the convex or concave portion of the inner cap. The projections or depressions are preferably provided on or around the cap, but are particularly preferably provided on the top. The number of protrusions or recesses may be one or more, respectively, or may be point-like or linear, so that the outer cap and the inner cap can be fixed with a slight movement. It is particularly preferred to configure.

The cross-sectional shape of the projection is preferably such that the projection protrudes vertically in the direction in which it is fixed, and that it projects obliquely in the direction in which it is detached. By protruding obliquely, the inner cap can be made hard to come off even when rotated in the detaching direction.

[0011] Although the mouth of the container is secured by the inner cap, the outer cap may be further configured to be secured to the mouth of the container. By doing so, the container can be double-fixed with the cap.

The material of the container or cap is preferably plastic. As the plastic, commonly used plastics are used, such as polyethylene terephthalate, a polyolefin, or a laminate of polyolefin containing gas barrier properties, a laminate of polyethylene, polyethylene and ethylene vinyl alcohol, or the like.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. FIG. 1 is a perspective view showing a container 1 to which a cap 2 of the present invention is fixed, in which an outer cap 3 and an inner cap 4 are not fixed. FIG. FIG. 3 is a perspective view showing a state in which the outer cap 3 and the inner cap 4 are fixed, and FIG. 3 shows a state in which the outer cap 3 and the inner cap 4 are not fixed. FIG. 4 is a cross-sectional view of the cap 2, and FIG.
5 is a cross-sectional view of the inside of the outer cap 3, FIG. 6 is a plan view of the inside of the inner cap 4, and FIG. ,
It is a perspective view of the convex part of an outer side cap. As shown in FIGS. 1 and 3, a container 1 to which a cap 2 of the present invention is fixed.
Since the outer cap 3 and the inner cap 4 are not fixed, the outer cap 3 is not fixed to the container 1. Therefore, even if the outer cap 3 rotates, the inner cap 4 does not rotate. When the outer cap 3 is pressed inward as shown in FIGS. 2 and 4, the convex portion 7 of the outer cap and the concave portion 10 of the inner cap engage, and
The outer cap is fixed by engaging the concave portion 8 of the outer cap with the convex portion 9 of the inner cap. The convex portion 7 of the outer cap is
As shown in FIG. 7, it protrudes at an angle of 90 ° C. in the fixing direction, and obliquely protrudes in the demounting direction.
Therefore, the projection 7 of the outer cap is not fixed.
Even if the concave portion 10 of the inner cap is slightly engaged with the inner cap, the force applied to the outer cap is not transmitted to the inner cap because it slides, and the inner cap is not detached.

[0014]

Effect of the Invention The container cap of the present invention has a double cap, and since no external force acts on the inner cap, the cap can be prevented from coming off. It is particularly preferable that the outer cap is transparent because the state of the inner cap can be easily identified.
