Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an aerosol container.

[0002]

2. Description of the Related Art As an aerosol container, there is known an aerosol container in which a shoulder cover and a jet head are fitted to an aerosol container body having a pouring pipe projected through a central portion of a top wall.

In general, a shoulder cover is provided with a flange-like top plate extending inward from an upper edge of a peripheral wall fitted to an outer peripheral upper end of a container body to cover a peripheral edge of an upper surface of the container body. It is provided for the purpose of protecting fingers and improving appearance.

[0004] In addition, the jetting head has a vertical pipe whose lower end is liquid-tightly fitted to the injection pipe, which is vertically suspended from the center of the top wall, and whose peripheral wall is vertically suspended from the peripheral edge of the top wall. The ejection horizontal cylinder extends further forward, and is configured such that, for example, by pushing down the ejection head, the built-in discharge valve is opened to eject the liquid.

[0005]

Since the base of the vertical cylinder is fitted to the outer periphery of the upper end of the spouting pipe, the ejection head is pulled upward despite being fitted in a liquid-tight manner. It is possible to remove it relatively easily. On the other hand, the shoulder cover is forcibly engaged with the locking ridge provided on the outer periphery of the container body by the engaging ridge provided on the inner periphery of the peripheral wall, so that the shoulder cover cannot be disengaged. Is common, and
Since the aerosol container body is generally formed of metal and the shoulder cover is formed of synthetic resin, the synthetic resin of the engaging portion tends to bite into the metal and is difficult to come off.

In addition to such circumstances, in recent years, there has been a demand for a separation treatment between synthetic resin and metal. After use, the synthetic resin material such as a shoulder cover is removed from a metal container and discarded. Is required.

[0007] In view of the above, the present invention does not risk that accessories such as the shoulder cover are securely fixed to the container during use and come off accidentally, and are relatively simple after use. The present invention proposes an excellent aerosol container which can be easily removed by a simple operation and can easily perform a sorting process.

11 is fitted so that it cannot be pulled out, and a synthetic resin shoulder cover 3 in which a flange-shaped top plate 12 extends inward from the upper end edge of the peripheral wall, and a vertical cylinder whose lower end is fitted to the injection pipe 7. 15 is provided vertically from the center of the top wall 16, the peripheral wall 17 is provided vertically from the peripheral edge of the top wall 16, and the horizontal cylinder 18 is ejected forward from the upper part of the vertical cylinder 15.
In the aerosol container comprising the synthetic resin ejection head 4 formed by extending the protrusion, the claw-shaped protrusion 21 is protruded from the peripheral wall 17 of the ejection head 4 and the claw-shaped protrusion 21 is insertable and the claw-shaped protrusion 21 can be inserted. The aerosol container is characterized in that a fitting hole 22 whose lower side is equal to or lower than the upper surface of the peripheral portion of the container body is formed in the peripheral wall 11 of the shoulder cover.

Further, in the container according to the second aspect of the present invention, the claw-shaped projection 21 is a claw-shaped projection formed by projecting an inclined ridge 23 which is inclined downward toward an outer edge at the center of one surface. It was configured as an aerosol container.

[0010] The container according to the third aspect of the present invention is arranged such that the fitting hole is
An aerosol container according to claim 1, wherein a cutout portion 24 is formed in the engaging ridge 10 of the portion formed by 22.

[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 jet head 4.

The aerosol container body 2 is provided with an injection pipe 7 projecting through the center of the top wall 6 of the body 5 and is provided so as to be able to push the injection 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 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 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 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 ridge 9 projecting from the lower part of the inner periphery is engaged with the locking ridge 9 provided on the outer peripheral upper end of the body part 5 so as to fit over the peripheral wall 11 so as not to come out. A flange-shaped top plate 12 extends further inward.

In the illustrated example, a locking ridge 9 is provided on the outer periphery of the annular wall 8.
Has been established. The shoulder cover 3 is formed by extending the lower portion of the peripheral wall 11 in a tapered shape along the tapered portion at the upper end of the outer periphery of the container body 5, and the top plate 12 is formed as the upper surface of the annular wall 8. A fitting cylindrical portion 13 that fits into the inner surface of the annular wall 8 extends downward from an inner peripheral edge of the annular wall 8 while extending inward with a gap that allows insertion of the claw-shaped protrusion. In addition, a cap 14 is detachably attached to the outer peripheral upper portion of the peripheral wall 11 by fitting a lower end portion thereof.

The jet head 4 is also made of a synthetic resin. A vertical cylinder 15 having a base end liquid-tightly fitted to the injection pipe 7 is erected from the center of the top wall 16 and a peripheral edge of the top wall 16. More peripheral wall
17, and a jetting horizontal tube 18 extends forward from the upper part of the vertical tube 15, and the tip thereof is formed as a jet outlet 19. The ejection head 4 may be formed separately from the shoulder cover 3 as shown in FIG. 1 or, as shown in FIG. 4, may be formed by thinning the front lower end of the peripheral wall 17 and the front end of the inner peripheral edge of the shoulder cover top plate 12. The hinges 20 may be integrally connected, and the whole may be formed by integral molding of a synthetic resin.
The ejection head 4 can be easily manufactured by being formed integrally with the shoulder cover 3.

According to the present invention, the claw-shaped projection 21 is projected from the peripheral wall 17 of the ejection head 4, and a fitting hole 22 into which the projection can be inserted and fitted is formed in the shoulder cover peripheral wall 11.

The claw-shaped projection 21 may be a simple flat plate. Alternatively, an inclined ridge 23 which is inclined downward toward the outer edge may be provided at the center of one surface thereof. By providing the inclined ridges 23, the thickness of the claw-shaped projections 21 can be reduced by the fitting holes 22.
Make it slightly smaller and easily insert it into the fitting hole 22,
In addition, the fitting can be performed densely.

The projecting position of the claw-like projection 21 is not particularly limited as long as it protrudes outward from the head peripheral wall 17. For example, as shown in FIG. Alternatively, as shown in FIG. 4, a configuration projecting rearward from the upper portion of the rear surface of the peripheral wall 17 can be adopted, but is not limited thereto.
In the former case, the projection 21 can be housed inside the shoulder cover 3, which is preferable in appearance.

The fitting hole 22 is configured such that the lower side thereof is at the same level or lower as the upper surface of the peripheral portion of the container body. Therefore, when the claw-shaped projection 21 is inserted and fitted through the fitting hole 22, the lower surface thereof can always contact the peripheral edge of the upper surface of the container body. Is configured to be detachable from the container body. Alternatively, when the lower side is expanded to a position closed by the outer periphery of the upper end of the container body, the projections 4 are disengaged by, for example, hitting the ejection head 4 against a desk or the like after fitting the claw-shaped projections 21. You can also. At this time, the claw-like projections 21 function as wedges.

A notch 24 may be formed in the engaging ridge 10 at the portion where the fitting hole 22 is formed. By providing the notch 24, the locking ridge 9 and the engaging ridge at the portion where the initial force is applied are provided.
Because there is no engaging part with the shoulder cover peripheral wall 11 of that part
Is easily deformed and lifted. As a result, it is easy to disengage both ends of the engaging portion of each ridge, and the shoulder cover 3 can be easily removed. The width of the notch 24 can be appropriately selected, but 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 fitting hole 22 because the ease of removal cannot be effectively extracted.

After the container 1 has used up the stored liquid, the ejection head 4 is removed, and the claw-shaped protrusion 21 is inserted and fitted into the fitting hole 22. At this time, when the shoulder cover 3 and the ejection head 4 are formed integrally, the ejection head 4 is detached by cutting the thin wall 20. Next, the shoulder cover 3 is removed by lifting the ejection head upward or hitting the outer end of the ejection head to a desk or the like, and the metal material and the synthetic resin material are separated.

[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 overhanging engagement between the locking ridge and the engaging ridge as in the prior art. There is no danger that it will be securely fixed and come off accidentally.In addition, a claw-like projection is projected from the peripheral wall of the ejection head, and the claw-like projection can be inserted and its lower side is the same as the upper surface of the peripheral part of the container body. The shoulder cover has a perforated hole that is below the level, so the shoulder cover can be easily removed after using up the stored liquid, and the synthetic resin material such as the shoulder cover can be separated from the metal container. Processing can be performed easily. Moreover,
Since the ejection head is used for removal, it can be easily separated without requiring special tools.

Also, in the case of the one provided with a claw-like projection having an inclined ridge that is inclined downward toward the outer edge and protruded at the center of one surface, the insertion fitting into the fitting hole is made easier. In addition to being able to carry out tightly, not only can the shoulder cover be removed by leverage by inserting and lifting it into the fitting hole, but if the fitting hole is large, the shoulder cover can be removed by the action of a wedge. There is an advantage that the range can be used widely.

Further, in the case where the notch is formed in the engaging ridge at the portion where the fitting hole is formed, the shoulder cover can be more easily separated from the container.
