Then, the inner periphery of the inner peripheral frame (31) is vertically protruded in correspondence with the locking portion (30) recessed in the container cover (23), so that the locking receiving portion (37) is formed. Has formed. This locking receiver
(37) is engaged with the locking portion (30), so that the shoulder cover
(25) and the container cover (23) are non-rotatably connected to form a rotation preventing function of the shoulder cover (25).

As shown in FIG. 1, the shoulder cover (25) is provided with an annular engaging ridge (38) perpendicular to the axial direction on the inner periphery of the inner peripheral frame (31). As shown in FIG. 4 and FIG. 5, the abutment ridge (38) is fitted to the engaging step (28) of the container cover (23) so that the shoulder cover (25) cannot be removed. ). Due to the engagement between the engagement step (28) and the engagement ridge (38), and the engagement between the engagement part (30) and the engagement receiving part (37), the shoulder cover (25) is moved up and down. Is also fixed so that it cannot advance or retreat.

Further, an annular flange (40) is formed in the opening (36) to protrude inward to prevent the shoulder cover (25) from sliding in the direction of the container body (21). Also, the outer frame
In (34), the upper portion is formed as a double cylinder, so that an insertion portion (41) of the actuator (26) is provided between the cylinders, and as shown in FIG. A mating groove (42) is provided. Thus, the container cover (23)
By fitting the shoulder cover (25) to the stem cover (25), the stem (35) projecting from the container cover (23) is arranged in the outer peripheral frame (34) of the shoulder cover (25) as shown in FIG.

The actuator (26) connected to the shoulder cover (25) is provided with a jet path (43) for aerosol contents therein as shown in FIGS.
A stem (35) is connected to the lower end of (43) so that the stem (35) can be pressed toward the container body (21).
Furthermore, a brush body (46) provided with a plurality of comb teeth (45) for applying a hair dye to the hair on the side surface of the jet path (43).
And a cylindrical connecting portion (47) for connecting to the shoulder cover (25) is provided on the outer periphery of the lower end of the ejection path (43).

Further, the ejection path (43) is provided with the ejection path (4).
The plurality of injection paths (48) communicating with the brush body (4) are connected to the brush body (4).
6) The projection is formed in the direction, and the injection port (50) is
It is open on the surface side of (46). In addition, several squirt paths (4
3) are arranged vertically in a row on the surface of the brush body (46). Then, a baffle plate (44) is provided on the surface of the brush body (46) facing the respective injection ports (50) so that the aerosol contents can flow out from both sides as shown in FIG. This prevents the contents of the aerosol sprayed from the spray port (50) from scattering outside the brush body (46) and can be widely spread between the comb teeth (45) of the brush body (46). And

On the outer periphery of the connecting portion (47), a pair of engaging projections (51) protrude outward, and as shown in FIG. 2, a crank-shaped engaging groove (42) of the shoulder cover (25). And the inside of the engagement groove (42) can be slid in a crank shape. The connecting portion (47) is formed so that the upper surface thereof can be pressed by a finger, and serves as a pressing portion (52) for pressing the actuator (26) toward the container body (21).

Further, the actuator (26) is provided with a shoulder cover.
When connected to (25), the aerosol container (27)
The length of the product becomes long, and the storage efficiency and appearance of the product on the display shelf may deteriorate, and it may be difficult to carry the product during transportation or purchase. Therefore, during manufacture and sale,
(26) is removed and stored compactly. At this time, if the opening (36) of the shoulder cover (25) is covered with a lid (not shown), the stem (35) can be protected and erroneous injection of the hair dye can be prevented.

The aerosol container (27) formed as described above
To use the actuator, attach the actuator to the shoulder cover (25).
(26) is connected. To do this, insert the shoulder cover (25)
The connecting portion (47) of the actuator (26) is inserted into the (41), and the actuator (2) is inserted into the crank-shaped engaging groove (42) provided in the outer peripheral frame (34) of the shoulder cover (25).
The engagement protrusion (51) of 6) is engaged. Then, the engagement groove (4
After sliding the connecting portion (47) in the axial direction along the crank of (2) and then in the circumferential direction, the actuator (26) is attached to the shoulder cover (25) as shown in FIGS. ) Can be connected. In this connection work, the actuator
Even if (26) is slid in the circumferential or vertical direction, the shoulder cover
Due to the function of preventing rotation of (25) and the container cover (23), the connection work can be performed reliably without shaking each component. The connection between the shoulder cover (25) and the actuator (26) can be carried out by appropriate known means, such as by providing a screw groove or an uneven groove in each of them and engaging them.

[0026] Also, by this connection, the actuator
The lower end of the ejection path (43) of (26) is connected to a stem (35) arranged in the opening (36) of the shoulder cover (25), and this stem (35) and the ejection path (43) are connected. The hair dye can be jetted.

By pressing the pressing portion (52), the lower end of the injection path (43) causes the stem (35) to be connected to the container body.
Push down in the direction (21). Then, the valve mechanism (24) is opened, and the hair dye in the aerosol container (21) is supplied to the stem (3).
Through 5), it flows out into the jet channel (43). The hair dye flows in the ejection path (43), and is then ejected to the outside from the ejection port (50) through a plurality of ejection paths (48) branched from the ejection path (43). Then, the hair dye injected from the injection port (50) strikes the U-shaped baffle plate (44) arranged facing the injection port (50), and thus the comb teeth (45) of the brush body (46). ) Does not fly outside. Thereafter, the hair dye is widely diffused to the surface of the brush body (46) from the gap between the outer periphery of the injection path (48) and the baffle plate (44), and
It adheres to (45). Then, by combing the hair with the comb teeth (45), a hair dye can be applied to the hair to perform a hair dyeing operation.

Also in this hair dyeing operation, the engagement between the engagement groove (42) and the engagement projection (51) ensures that the shoulder cover (25) and the actuator (26) are securely connected. ,
Since the shoulder cover (25) and the container cover (23) are non-rotatably connected by the engagement between the locking portion (30) and the locking receiving portion (37), each component may rotate or wobble. Without using it, it is possible to use it with excellent operability.

Since such a rotation preventing function is provided not on the container body (21) but on the metal container cover (23) which is excellent in durability and shape stability and is easy to form,
Deformation and abrasion hardly occur even when an impact is applied during the coating operation, and it is possible to maintain an excellent rotation preventing function.
Also, since the container body (21) can be formed with a uniform thickness,
Without impairing pressure resistance, avoiding dangers such as rupture,
It is possible to obtain an aerosol container (27) having excellent safety, to simplify the working process and technology, and to form a product at low cost.

When the hair dyeing operation is completed, the actuator (26) is removed from the shoulder cover (25) again, and
It can be discarded compactly or separately. If the hair dye remains, it can be stored and stored compactly, and the next hair dyeing operation can be performed well.

In the above embodiment, the actuator
(26) is formed in a brush shape, and is an aerosol container for hair dyeing.
Although used as (27), it may be formed by connecting a brush, an impregnated body such as a sponge member or a felt member, and the like. The aerosol contents ejected from the stem (35) are included in these members, and various operations can be performed by bringing the contents into contact with the hair, the vehicle body, and other objects.
In addition, various actuators (26) provided with injection nozzles having different injection modes are formed, and these are selectively connected to the shoulder cover (25) according to the intended use, and the aerosol contents are ejected to the intended use part. It may be formed as follows. In any of the above-mentioned methods of use, since the shoulder cover (25) is non-rotatably fitted with the container cover (23), the intended coating operation can be performed satisfactorily.

In the above embodiment, the container cover (23)
The locking portion (30) is formed by recessing the outer periphery of the container cover (23). However, in another different second embodiment, as shown in FIGS. By protruding, a locking portion (30) is formed in the vertical direction. And
Eight locking portions (30) are arranged at equal intervals in the circumferential direction. Corresponding to the projecting locking portion (30), a shoulder cover
The inner peripheral frame (31) of (25) forms an engagement receiving portion (37) by recessing the inner periphery in the vertical direction.

Then, as shown in FIG. 8 and FIG.
(37) and the engaging portion (30) are engaged to form a shoulder cover.
The rotation of (25) is favorably prevented, and constitutes a rotation prevention mechanism. As shown in FIG. 7, the inner peripheral frame (31) of the shoulder cover (25) has a projection formed at an interval between the respective engagement receiving portions (37) on the inner periphery. ) Are provided in the circumferential direction. Then, as shown in FIG. 9, the engaging ridge (38) is fitted into the engaging step (28) of the container cover (23), and the annular flange is formed.
By disposing the upper surface of the container cover (23) against (40), the shoulder cover (25) is prevented from falling off from the container cover (23).

Then, similarly to the first embodiment, by connecting the target actuator (26) to the shoulder cover (25), the aerosol contents can be jetted and the target application operation can be performed. Since the container cover (23) and the shoulder cover (25) are securely fitted in a non-rotatable manner also in the operation of attaching / detaching or applying the actuator (26), it is possible to use with excellent operability. Further, since the container cover (23) is formed separately from the container body (21) in which the pressure resistance is important, the locking portion (30) provided on the outer periphery of the container cover (23).
There are few restrictions on the shape and the like, and the formation is easy.

In the above embodiment, the capacity is 200 cc.
The aerosol container of the present invention is used, but the rotation preventing function of the shoulder cover of the present invention can be used for a relatively small aerosol container having a capacity of 220 cc or less. However, it is not preferable to use a large aerosol container having a capacity of more than 220 cc because it is difficult to implement the container cover in terms of molding.

[0036]

Since the present invention is constructed as described above, it has a function of preventing rotation of the shoulder cover of a relatively small aerosol container having a capacity of 220 cc or less, is easy to mold, and has excellent shape stability and durability. By providing the cover on the container cover, a product having excellent functionality can be formed by a simple manufacturing technique. In addition, the pressure resistance of the aerosol container can be favorably formed, and the safety of the product is improved.
And even if the actuator is attached or detached or the aerosol contents are ejected by this actuator, each part does not rotate or wobble, and excellent operability can be realized.
