[0012]

Embodiments of the present invention will be described below with reference to the drawings. The container 1 of the present invention includes an aerosol container body 2, a shoulder cover 3, and a nozzle 4.

The aerosol container body 2 has a pouring pipe 7 protruding from the center of the top wall 6 of the body 5 and is provided so as to be able to push the pouring pipe 7 in an upwardly biased state. A push-down type or a so-called tilt type in which the pouring pipe 7 is always urged in the upright direction and can be tilted can be adopted.

These are provided with a well-known liquid ejection mechanism inside, and when the ejection pipe 7 is pushed down or tilted, a built-in discharge valve (not shown) is opened, and the tip of the ejection pipe 7 is opened. It is configured so that more liquid is ejected.

The container body 2 in the illustrated example is of a push-down type that opens by pushing down an injection pipe 7, and has a body 5
An annular wall 8 formed by winding the top plate peripheral portion around the upper surface peripheral portion is provided upright.

The shoulder cover 3 is made of synthetic resin and covers the peripheral edge of the upper surface of the container body 5, and is provided for the purpose of protecting the user's fingers and improving the appearance. The engaging ridge 9 provided on the lower part of the inner periphery is engaged with the locking ridge 9 provided on the upper peripheral part of the outer periphery of the body part 5 so that the engaging ridge 10 is fitted over the peripheral wall 11 so as not to come out. A flange-shaped top plate 12 extends further inward. In the example shown, the surrounding wall
The upper part of 11 is reduced in diameter, and the peripheral wall of the cap 13 is fitted to the reduced diameter portion. In addition, the locking ridge 9 of the container body
Is provided around the outer periphery of the annular wall 8.

The nozzle 4 is also made of synthetic resin, and has a cylindrical shape in which the base end is fitted in a liquid-tight manner to the pouring pipe 7 and is erected upward. In the illustrated example, a finger contact portion 14 is provided in which a vertical wall extends vertically from an outer peripheral edge of a flange-like top plate extending outward from a vertically central portion of the outer periphery of the nozzle 4. Further, the lower end of the front surface of the vertical wall of the finger contact portion and the front portion of the inner peripheral edge of the shoulder cover top plate 12 are integrally connected by a thin hinge 15, and the whole is formed by integral molding of synthetic resin. The nozzle 4 can be easily manufactured by being formed integrally with the shoulder cover 3 as in the illustrated example.
Considering the point used for removing the shoulder cover 3, the shoulder cover 3
Alternatively, it may be formed separately.

In the present invention, the nozzle 4 removed from the injection pipe 7
An insertion hole 16 into which the upper part can be inserted and the tip of the inserted nozzle 4 can be in contact with the upper surface of the container body 2 is formed in the peripheral wall 11 of the shoulder cover. It is configured so that it can be easily removed from the body 2.

That is, after the stored liquid has been used up, the nozzle 4
Is removed, and the tip of the nozzle 4 is inserted through the insertion hole 16 as shown in FIG. At this time, the shoulder cover 3 as shown in the illustrated example is used.
When the nozzle 4 and the nozzle 4 are integrally formed, the thin hinge 15 is cut to remove the nozzle. Then, FIG.
As shown in (b), the shoulder cover 3 can be easily removed by lifting the rear part of the nozzle 4 and using the principle of leverage.

In this embodiment, the notch 17 is formed in the engaging ridge 10 at the portion where the insertion hole 16 is formed. This notch
By providing 17, there is no engaging portion between the locking ridge 9 and the engaging ridge 10 at the portion where the force is initially applied, so that the shoulder cover peripheral wall 11 at that portion is easily deformed and lifted. It is easy to disengage both ends of the engaging portion of the ridge, and the shoulder cover 3 can be easily removed. The width of the notch 17 can be appropriately selected. However, if the width is too large, there is a possibility that the engagement between the shoulder cover and the container body may be insufficient. It is preferable to select a width slightly longer than the diameter of the insertion hole 16 because the ease of removal cannot be effectively extracted.

Further, as shown by a two-dot chain line in FIG. 2, a sealing material 18 which can cover the insertion hole 16 and can be peeled off may be provided on the outer surface of the shoulder cover peripheral wall 11.

FIGS. 4 to 6 show another embodiment of the present invention.
In the present embodiment, in the above-described embodiment, a tapered projection 19 having an upper surface descending outward from the upper outer surface of the nozzle 4.
And a vertically elongated elliptical shape perforated over a portion of the shoulder cover peripheral wall 11 to be fitted to the container body and the upper portion thereof, and a tip of a nozzle detached from the injection pipe 7 at an upper opening portion. Is inserted, and an insertion hole 16a is provided in the lower closed portion so that the projection 19 can be inserted.

The rest of the configuration is the same as that of the above-described embodiment, and the same reference numerals are given and the description is omitted. In the case of the present embodiment, FIG.
As shown in FIG. 6B, the tip of the removed nozzle is inserted and fitted into the upper part of the insertion hole 16, and then, as shown in FIG.
By hitting the rear end of the nozzle 4
The upper surface of the container body 2 and the shoulder cover 3 are pushed open, and the shoulder cover 3 is easily detached.

[0024]

As described above, in the container of the present invention, the shoulder cover is fixed to the container body so as not to be disengaged by the engaging ridge and the engaging ridge, as in the prior art, so that the container can be reliably used. There is no danger of accidental detachment, etc., and it is possible to insert the upper part of the nozzle removed from the pouring pipe, and the insertion hole where the tip of the inserted nozzle can contact the upper surface of the container body. Since the shoulder cover is formed in the peripheral wall of the cover, the shoulder cover can be easily detached after the stored liquid has been used up, and the processing of separating the synthetic resin material such as the shoulder cover from the metal container can be easily performed. In addition, since the nozzle is used for removal, it can be easily separated without requiring any special tool.

Further, in the case where the notch is formed in the engaging ridge of the insertion hole perforated portion, the shoulder cover can be more easily separated from the container body.

Further, a tapered projection having an upper surface descending outward is provided on the side of the upper outer surface of the nozzle, and a portion of the shoulder cover peripheral wall fitted to the container body and over the upper portion thereof. It has a vertically elongated elliptical shape, and the upper opening has an insertion hole into which the tip of the nozzle removed from the injection pipe can be inserted, and the lower blocking portion has an insertion hole configured to allow a projection to be inserted. When the nozzle and the projection are wedge-operated, the shoulder cover can be easily opened by hitting the rear end of the nozzle to a desk or the like with the nozzle tip inserted and fitted into the insertion hole opening. It can be separated.

Also, in this case, the provision of the notch makes it easier to separate the shoulder cover from the container.
