Further, the aerosol container according to claim 1 is a cylindrical nozzle 4a having a front surface at a lower end portion connected to a front portion of an inner peripheral edge of a top plate 12 of a shoulder cover via a thin hinge 18.

[0011]

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 squirt part 4.

The aerosol container body 2 is mainly made of metal, and has an injection pipe 7 protruding through the center of the top wall 6 of the body 5, and pushes the injection pipe 7 in an upwardly biased state. It is possible to employ a so-called push-down type which is provided so as to be possible, or a so-called tilt type in which the pouring pipe 7 is always urged in the erect direction and tiltable.

These are equipped 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 shown in the figure has an annular wall 8 formed by tapering the outer peripheral upper end of the body 5 into a tapered shape, and by winding the top plate periphery around the upper surface periphery of the body 5. Has been established.

The shoulder cover 3 is made of a synthetic resin, 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 projection 9 protruding from the lower part of the inner periphery is engaged with the locking projection 9 provided on the upper end of the outer periphery of the body 5 so that the engaging projection 10 protrudes from the lower peripheral part of the peripheral wall 11. A flange-shaped top plate 12 extends inward from the edge. Further, an outer peripheral wall 13 is vertically suspended from the upper peripheral part of the peripheral wall 11 in a double cylindrical shape, and the lower end edge thereof is suspended down to the lower end edge of the reduced diameter portion of the container body 5. In the illustrated example, a locking ridge 9 is provided around the outer periphery of the annular wall 8.

In the present invention, a pair of cuts extending upward from the lower end of the shoulder cover peripheral wall 11 are provided at intervals at the rear of the shoulder cover peripheral wall 11 so that the shoulder cover 3 can be easily removed from the container body 2 after the stored liquid has been used up. Grooves 14 and 14 are provided, and a finger hook 15 is provided which bulges outward from the lower end of the rear part of the outer peripheral wall 13 to the upper part.

By providing the cut groove and the finger hook portion, for example, when the finger cover portion 15 is pulled up by pressing the shoulder cover 3 or the jetting portion 4, the lower portion of the peripheral wall 11 therebetween is raised due to the presence of the cut grooves 14, 14. The engaging ridge 9 and the engaging ridge 10 at that portion are easily disengaged. Next, since the engaging ridge 10 in front of each of the cut grooves 14 forms an end in each of the cut grooves 14, the peripheral wall 11 between the cut grooves 14 is easily disengaged from the part by lifting upward. Therefore, the shoulder cover 3 is configured to be easily removed.

The engaging ridge 10 may be provided only at a position in front of the cut grooves 14 at the front portion of the shoulder cover peripheral wall 11, as shown in the illustrated example. In this case, the rear portion of the shoulder cover peripheral wall may be provided. Since there is no engaging portion between the cut grooves 14, 14, that is, there is no engaging portion at the portion where the initial force is applied, the rear peripheral wall 11 between the cut grooves is more easily lifted, and the shoulder cover Can be removed.

The ejection section 4 has a built-in liquid flow path a having one end fitted to the ejection pipe 7 in a liquid-tight manner and the other end communicating with the ejection port 16. Or
A vertical cylinder whose lower end is liquid-tightly fitted to the injection pipe 7 is vertically provided from the back surface of the top wall, and a peripheral wall is vertically provided from the peripheral edge of the top wall. A jet head type consisting of a cylinder or the like can be adopted, and its specific structure may be appropriately selected depending on the above-described type of the container body and the like.

In the illustrated example, an example is shown in which the ejection portion 4 is a cylindrical nozzle 4a, and the upper portion of the cylindrical portion is erected at a front eccentric position via a step portion, and is at the same level as the upper surface position of the step forming portion. A push button 17 protrudes from the lower part of the rear outer surface by hanging a vertical wall through the top plate of the rear surface. The front surface of the lower end portion is integrally connected to the front edge of the inner peripheral edge of the top plate 12 of the shoulder cover 3 via a thin hinge 18.

The spout 4 is formed integrally with the shoulder cover 3 as shown in FIG.
Alternatively, it may be formed separately.

After the aerosol container 1 as described above is used up, the push button 17 is pressed and the finger hook 15 is pulled up from below as shown in FIG. The engagement of the ridge 10 is disengaged from the rear part, and finally the ejection part 4 is disengaged and the shoulder cover 3 is easily disengaged.
And the ejection part 4 can be removed from the container body 2.

[0023]

As described above, in the container of the present invention, the shoulder cover 3 is fixed to the container body 2 so as not to be disengaged by the overhanging engagement between the locking ridge 9 and the engaging ridge 10, as in the prior art. Therefore, there is no danger of being securely fixed and inadvertently coming off during use, and a pair of cutting grooves 14, 14 extending upward from the lower end are provided at intervals at the rear of the shoulder cover peripheral wall 11, The outer peripheral wall 13 vertically suspended from the outer peripheral upper part of the peripheral wall 11 is provided with a finger hook 15 which bulges outward from the lower end of the rear part of the outer peripheral wall 13 so that the shoulder cover can be easily used after the stored liquid is used up. Can be removed, and the separation process between the synthetic resin material such as the shoulder cover and the metal container can be easily performed. Moreover,
It can be easily detached without any special tools.

Further, in the case where the engaging ridge 10 is provided only at a position forward of each cut groove in the front portion of the peripheral wall of the shoulder cover, the shoulder cover can be more easily separated from the container body.

Further, the lower end is fitted up to the pouring pipe 7 in a liquid-tight manner and rises upward, a push button 17 is protruded below the rear outer surface, and the front end of the lower end is formed inside the top plate 12 of the shoulder cover. In the case where the ejection part 4 is configured as a cylindrical nozzle 4a connected to the front part of the periphery via a thin hinge 18, if the finger catch is pulled up by pressing the push button, the principle of leverage makes it easier. Since the shoulder cover comes off sequentially from the rear, and then the nozzle comes off in a series of operations, it becomes easier to remove the synthetic resin material.
