Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aerosol container in which a socket for holding a jet button with a long nozzle facing downward is provided integrally on a peripheral surface portion by projecting and is detachably mounted on the top of the aerosol container. It concerns a cover cap.

[0002]

2. Description of the Related Art A cover cap integrally formed with an injection button socket with a long nozzle of this type is actually used as a cover cap.
It is well known from Japanese Unexamined Patent Publication No. 87160 that the jet button is detached from the socket when the long nozzle is used, and the cap is detached from the top of the head and mounted on the stem.
Therefore, if there are multiple types of injection buttons to be held by the cover cap of the same shape that is manufactured by injection molding, molds can be independently prepared unless one cover cap is attached to a plurality of sockets at different locations. It was necessary to prepare and manufacture multiple types of cover caps.

[0003]

SUMMARY OF THE INVENTION In view of the above-mentioned problems, the present invention provides an aerosol container which is manufactured by the same mold and which can form two kinds of sockets in a switchable manner at the same place on the peripheral surface of the cap. The purpose is to provide a cover cap.

[0004]

In order to achieve this object, the invention according to claim 1 is removably mounted on the crown of the aerosol container so as to cover the stem region projecting from the crown. In addition, in the cover cap of the aerosol container in which the socket for holding the injection button with the long nozzle facing downward is integrally formed on the peripheral surface so as to project, the socket detachably engages the injection button with the large elongated nozzle. Consists of a large socket with an engaging groove and a small socket that is connected to the lower end of this large socket via an integral hinge and that is detachably engaged with the engaging groove. It is characterized in that an engagement groove for detachably engaging the ejection button with a long nozzle is formed.

When the cover cap holds the jet button with a small elongated nozzle, the small socket is mounted in the engagement groove of the large socket. When holding the jet button with a large long nozzle, detach the small socket from the large socket.

BEST MODE FOR CARRYING OUT THE INVENTION A cover cap for an aerosol container according to an embodiment of the present invention will be described with reference to FIGS. 1 to 3. The mounting cap 2 attached to the top of the aerosol container 1 is provided with an injection valve so that the spring-biased stem 3 projects upward. An ejection head is attached to this stem, and when it is pushed down, the contents are ejected.

The outer cap portion of the cover cap 9 is an aerosol container 1 so as to cover such a stem portion.
It is formed in a shape that surrounds the lower end of the shoulder portion 1a and covers the upper side thereof, and the inner cylinder portion is detachably attached to the curl portion 2a of the mounting cap 2. On the peripheral surface 9a of the outer cylindrical portion of the cover cap 9, the large socket 10
And a socket 8 composed of a small socket 20
Resin is injected from the injection port 9b on the upper surface and is integrally formed by injection molding.

The large socket 10 has a U-shaped engaging groove 1 which is opened upward by a peripheral wall portion 12 protruding from the peripheral surface 9a.
1 is formed and a large injection button 1 with a long nozzle 19
8 is detachably engaged. Engagement groove 11
The bottom surface 11a is slightly flatter than the peripheral surface 9a and is formed in a flat shape, and the air vent hole 13 of the cover cap 9 is formed to ventilate the inside to suppress the deformation of the cover cap 9.

The small socket 20 has a bottom surface portion 21a, and a peripheral wall portion 22 of the outer peripheral surface corresponding to the engagement groove 11 forms a U-shaped engagement groove 21 opening upward, and is relatively outside. A small injection button 28 with a long nozzle 29 having a small diameter is detachably engaged. The small socket 20 has an integral hinge portion 1 at an intermediate position.
It is connected to the large-sized socket 10 via connecting arms 14 and 24 in which 4a is formed. The connecting arm 14 is retracted by the plate thickness of the connecting arm 24 connected to the lower end of the peripheral wall portion 22 and is installed under the lower end of the peripheral wall portion 12. The height and the vertical width of the peripheral wall portion 22 correspond to the depth and the vertical width of the engagement groove 11, so that the front surface of both sockets 10, 20 in the state where the small socket 20 is engaged with the engagement groove 11. The part and the upper end surface are set to be flush with each other.

Further, on the peripheral surface 9a located below the large-sized socket 10, a pair of projecting pieces 26 are formed in correspondence with the distance between both sides of the peripheral wall portion 22. As a result, the small socket 20 which is released from the engaging groove 11 and folded back to the peripheral surface 9a is held by engaging the peripheral wall portion 22 with the projecting piece 26. Further, on the back surface of the bottom surface portion 21 a of the small socket 20, a concave curved groove 23 having a shape corresponding to the long nozzle 19 is formed.

The method of using the cover cap 9 of the aerosol container thus constructed is as follows. As shown in FIG. 2A, the small injection button 28 is attached to the cover cap 9
1A, the small socket 20 is engaged in the engagement groove 11 of the large socket 10 in the same plane without protruding the front surface and the upper end surface forward and upward as shown in FIG. 1A. The injection button 28 is inserted into the engagement groove 21 so that the elongated nozzle 29 faces downward from the opening above the engagement groove 21. In this state, the injection button 28 is detachably held on the peripheral surface 9a of the cover cap 9, and the internal stem 3
Is equipped with a normal injection button. However, the stem 3 may be an aerosol container dedicated to a long nozzle, which is not provided with a normal injection button.

In use, the injection button 28 is detached upward, the cover cap 9 is removed, and the long nozzle 29 is attached to the stem 3 and directed forward, as shown in FIG. When the ejection button 28 is detached, the folded connection arms 14 and 24 restrain the ejection button 28 from being pulled out in an interlocking manner.

As shown in FIG. 2B, when attaching a relatively large injection button 18 to the cover cap 9, the socket 20 is detached from the socket 10 and inverted with the integral hinge portion 14a as a fulcrum. The mating groove 21 is locked to the projecting piece 26. The injection button 18 is
The long nozzle 19 having a relatively large outer diameter is partially housed in the groove 23 and engaged with the engaging groove 11.

As the shape of the engaging groove, various modifications are conceivable, such as a shape in which the upper side is closed so that the engaging groove can be attached and detached by forward and backward operations.

[0015]

According to the first aspect of the present invention, it is possible to switch the types of the ejection buttons for the long nozzles formed on the cap having the same shape, and therefore, the two types of ejection buttons can be attached to the same place. Can be manufactured without preparing two types of molds, which is advantageous in manufacturing cost.

According to the second aspect of the present invention, since the engaging groove is formed in a U-shape, the small socket or the injection button can be easily attached / detached in the vertical direction to engage the small socket. There is no protruding part and it looks good.
