Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aerosol sprayer, and more particularly to an aerosol sprayer capable of easily separating an aerosol container and a cover member.

[0002]

An aerosol sprayer in which a plastic sprayer and a cover member are attached to a metal aerosol container has been well known.

In a conventional container, a fitting tube of the cover member is firmly fitted to a mounting ring formed on a periphery of a head of the aerosol container so that the cover member does not come off from the aerosol container during use. I was When disposing of the used container, the aerosol container with the sprayer and the cover member attached was directly discarded.

[0004] Recently, when collecting waste, it has been required to separate metal and plastic and place them at a collection place in order to reuse resources. However, the conventional aerosol-type container has a problem that it is difficult to separate the cover member from the aerosol container, and it is necessary to use some kind of device to separate the cover member from the cover member. However, even if the collected aerosol container is separated in a reprocessing plant, the operation is not easy.

An object of the present invention is to provide an aerosol sprayer in which a cover member is firmly fitted to an aerosol container and can be easily separated after use, with the technical problem of solving the above-mentioned problems. Aim.

[0006]

In order to achieve the above technical object, the present invention provides, as an aerosol sprayer, an aerosol container having a stem and a mounting ring formed on the periphery of a head, and attached to the stem. In an aerosol sprayer having a sprayer and a cover member fitted to a mounting ring, the cover member includes an inner cover and an outer cover, and the inner cover extends from a lower end of the base cylinder and the inner circumference of the mounting ring. And a conical cylinder that spreads downward with the upper end as a step from the middle of the base cylinder, and the outer cover has an opening that is inserted into the base cylinder of the inner cover. It has a top wall and a fitting cylinder provided with a bulging ring at the lower end to be engaged with the outer circumference of the mounting ring, and a plurality of cutout grooves having a fixed length from the lower end on the inner circumference. Adopt a configuration that

[0007]

Next, embodiments of the present invention will be described with reference to the drawings. 1 and 2, A is an aerosol container, B is a cover member attached to the aerosol container, C is a sprayer, and D is a cap. The aerosol container A is made of metal and the other members are made of synthetic resin.

The aerosol container A is attached to the container body 1 and a valve member having a stem 2 urged upward by a spring, and supports the valve member and seals the opening of the container head. And a mounting ring 4 for mounting the cover member B on the periphery of the container head by the mounting portion of the mountain cup 3. The spray liquid is enclosed in the aerosol container together with the high-pressure gas.

The cover member B includes an inner cover B1 and an outer cover B2. As shown in FIG.
1 includes a cylindrical base cylinder 5 and a conical cylinder 6 that extends downward from an intermediate portion of the outer periphery of the base cylinder 5. The upper end of the conical cylinder 6
A stepped portion 7 protrudes from the outer periphery of the base cylinder 5,
Are provided with slits 8 at regular intervals on the circumference. A bulging ring 9 is provided on the outer periphery of the upper end of the base cylinder 5, and a fitting cylinder 11 having a slit 10 provided at a constant interval on the circumference and having an inner diameter enlarged at the lower end is provided vertically. .

As shown in FIG. 4, the outer cover B2 has a fitting tube 12, a diameter reduced from the fitting tube 12, and a top wall 13 at the upper end.
And a cap holding cylinder 14 provided with Top wall 13
Is provided with an opening 15 into which the inner cover B1 is inserted, and a swelling ring 16 is provided on the outer periphery of the upper end of the cap holding cylinder 14. A swelling ring 17 protruding inward is provided on the inner periphery of the lower end of the fitting cylinder 12, and a notch groove 18 having a predetermined length from the lower end is formed on the inner periphery at a predetermined interval. ,
A thin portion is formed. The circumferential interval of the notch groove 18 is the same as that of the slit 8 formed in the conical cylinder 6 of the inner cover B1, and the number of the slit 8 and the notch groove 18, the notch groove 1
The depth and shape of the groove 8 are appropriately set according to the mechanical properties of the material used.

As shown in FIG. 2, the atomizer C has a fine pore 20
Is provided, and a stem insertion hole 22 and an inner hole 23 connecting the both are provided. The stem insertion hole 22 is fitted to the stem 2 to be directly attached to the aerosol container A. The cap D includes a top wall 25 and a side cylinder wall 26, and a bulging ring 27 is provided on the inner periphery of the lower end of the side cylinder wall 26.

Next, the attachment of the cover member B to the aerosol container A and the operation at that time will be described. Attachment is performed by first fitting the outer cover B2 into the inner cover B1 and joining them together to assemble the cover member B. At this time, the opening 15 of the top wall 13 of the outer cover B2 descends over the swelling ring 9 at the upper end of the base cylinder 5 of the inner cover B1, and the outer cover B2 is connected to the swelling ring 9 of the inner cover B1 and the stepped portion 7. The vertical position is regulated by this, and it is inserted into the base cylinder 5.

Next, the assembled cover member B is fitted to the mounting ring 4 of the aerosol container A. At the time of fitting, first, relative positions in the circumferential direction of the inner cover B1 and the outer cover B2 are determined by marks, irregularities, etc. (not shown) provided on the respective notches so that the notch groove 18 and the slit 8 coincide with each other. To engage with the mounting ring 4.

Next, when the outer cover B2 is pressed, the swelling ring 17 provided on the inner periphery of the lower end of the fitting tube 12 of the outer cover B2 is pressed.
However, the cover member B is firmly attached to the aerosol container A by fitting the lower part of the outer circumference of the mounting ring 4 and fitting the fitting tube 11 of the inner cover B1 to the inner circumference of the mounting ring 4. . At this time, the lower end of the conical cylinder 6 of the inner cover B1 is joined to the outer peripheral edge of the upper end of the mounting ring 4.

In use of the container, when the cap D is removed and the sprayer C is pressed, the sprayer C pushes down the stem 2 and the contents are sprayed from the spray nozzle 21 in response to the pushing down.

Next, separation of the cover member B from the aerosol container A will be described. When disposing of the used container, the sprayer C is removed from the aerosol container A, and the inner cover B1 is pushed down.
Descends along the inner circumference of the mounting ring 4, and the lower end of the conical cylinder 6
It detaches from the upper end of the mounting ring 4, slides outward and expands, and acts to expand the fitting tube 12. Due to its spreading action,
As shown in FIG. 5, the notch groove 18 of the fitting cylinder 12 is cut open to form a slit 18 a, the fitting cylinder 12 is expanded, and the bulging ring 17 at the lower end is detached from the mounting ring 4. Thus, the fitting state between the fitting cylinder 12 and the mounting ring 4 is released. Thus, the cover member B can be easily removed from the aerosol container A.

[0017]

Since the present invention is configured as described above, it has the following effects. In the aerosol sprayer, since the cover member of the sprayer can be separated from the mounting ring of the aerosol container, the metal aerosol container, the cover member made of synthetic resin, and the sprayer can be separately disposed.
