[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spout, and more particularly to a spout attached to an aerosol container.

[0002]

2. Description of the Related Art For example, many hairdressing compositions having a structure in which contents are discharged from a container in the form of foam are sold. This type of container has a configuration in which an aerosol container is filled with a liquid content (such as a hairdressing agent) together with a propellant (eg, LPG). The liquid content filled in the aerosol container is urged by the propellant by a user's spraying operation and is sprayed to the outside in a foamy state.

FIG. 8 and FIG. 9 show an enlarged view of the vicinity of the injection section of a conventional container of this kind. In each figure, 1 indicates an aerosol container, 2 indicates a valve, 3 indicates a stem, and 4 indicates a spout.

[0004] As described above, the aerosol container 1 is filled with contents such as a hairdressing agent and a propellant therein. The valve 2 is a valve body that opens and closes when the stem 3 is swung or pressed, and is closed when the stem 3 stands upright and opened when the stem 3 is swung or pressed. It has a configuration.

The spout 4 has a structure in which a fitting part 5, a base part 6, a nozzle part 7, and an operation button 8 are integrally formed. The fitting part 5 is for fixing the spout 4 on the upper part of the aerosol container 1, and the fitting part 5 and the base part 6 are connected via a connecting part 9. Since the connecting portion 9 is narrow, the base portion 6 can be displaced with respect to the fitting portion 5. Further, the nozzle portion 7 is connected to the stem 3, and the contents ejected from the stem 3 pass through holes formed in the nozzle portion 7 and are ejected from the nozzle tip.

In order to eject the contents in the container having the above structure, the operation button 8 is pressed. Thereby, the base 6
8 is flexibly displaced around the connecting portion 9 in the direction of arrow A in FIG. 8, whereby the stem 3 is swung or pressed, whereby the valve 2 is opened and the contents are ejected from the tip of the nozzle portion 7. Had been configured.

As described above, the valve 2 ejects the contents when the stem 3 is swung, and the stem 3 is swung or pressed in a direction other than the direction indicated by the arrow A in FIG. Even if it does, the contents will be jetted. Also,
As described above, the conventional spout 4 has a configuration in which the base portion 6 is displaced about the connecting portion 9, so that the arrow A
It is configured to be displaceable in directions other than the direction. Therefore, in the spout 4 having the above configuration, for example, when the spout 4 is displaced in any direction, the cap is detached when the spout 4 is displaced in any direction. Then, there is a problem that the inside of the bag may be stained, or the propellant may be exhausted before the entire contents are not used.

In order to solve the above-mentioned problems, the inventor of the present invention has first made the mounting portion rotatable at the upper end of the aerosol container, and when the mounting portion is at the predetermined rotation position, the base portion. And a spout provided with a lock mechanism for restricting displacement of the base portion and releasing the displacement restriction of the base portion when the mounting portion is at a rotation position different from the predetermined position (actually, No. 2-78988).

According to the spout according to the above-mentioned application, the displacement of the base portion can be locked and unlocked by simply rotating the attachment portion, and the displacement of the base portion is restricted in the locked state, so that the contents are locked. Discharge is prevented.

[0010]

[Problem to be solved by the invention] In the above spout,
The displacement of the base can be locked and unlocked with a simple operation, and the discharge of the contents can be prevented.

However, in the spout having the above structure, it is necessary to make the mounting portion rotatable with respect to the base portion. Therefore, the base portion and the mounting portion are formed independently of each other and mounted on the aerosol container. That was being done.

For this reason, the mold for the base portion and the mold for the mounting portion must be separately manufactured, which increases the cost of the mold, which affects the product cost and increases the product cost. there were. Further, since the base and the mounting portion are separately mounted on the aerosol container, there is a problem that the assembling work is troublesome.

The present invention has been made in view of the above points, and has as its object to provide a spout with improved moldability and assemblability.

[0014]

In order to solve the above-mentioned problems, according to the present invention, by attaching to an aerosol container and forming an engagement step portion, the attachment portion is operated by taking out the contents. An operating part for opening the aerosol valve provided on the aerosol container, a nozzle part for discharging the contents, and a base part formed with a flange part engaging with the engaging step part The mounting portion is configured to be rotatable at the upper end portion of the aerosol container, and when the mounting portion is at a predetermined rotation position, the engaging step portion engages with the flange portion and the base portion. When the engaging step is in a rotational position different from the predetermined position, the engaging step and the flange are separated from each other to allow the base to be displaced. In the above, the mounting part and the base part are integrated When the attachment portion is at a predetermined rotation position, the joint portion is formed by being cut at the time of attachment to the aerosol container to separate and attach the attachment portion and the base portion independently. And a lock projection which is engaged with the joint portion and locks the rotation of the mounting portion.

[0015]

According to the spout constructed as described above, the mounting portion and the base portion can be formed integrally, and the cost of the mold can be reduced. Further, since the mounting portion and the base portion can be collectively mounted on the aerosol container, the assembling work can be simplified. Further, by providing the lock projection, it is possible to recognize that the attachment portion is at the lock position by a click feeling generated when the joint portion and the lock projection are engaged.

[0016]

Next, an embodiment of the present invention will be described. FIG.
Shows spout 10 which is one embodiment of the present invention,
FIG. 2 is an exploded perspective view showing the spout 10 attached to the aerosol container 11.

The spout 10 is attached to an aerosol container 11 filled with contents such as a hairdressing material. The aerosol container 11 is a cylindrical airtight container, and a mountain cap 12 is attached to an upper portion thereof. A valve 13 is provided at a central position of the mountain cap 12, and a stem 14 is provided upright on the valve 13. The stem 14 can swing and move up and down.
The valve 13 is opened by swinging and vertically moving the valve 4, and the contents are urged by the propellant and discharged from the stem 14.

The spout 10 is roughly attached to the mounting portion 1.
5 and a base 16.

The mounting portion 15 has a substantially cylindrical shape, and a skirt portion 17 formed below the mounting portion 15 is
1 can be fitted into the upper end. This hakama part 1
The fitting portion 15 is attached to the aerosol container 11 by fitting the 7 into the aerosol container 11. At this time, by appropriately selecting the fitting force, the mounting portion 15 can be rotated above the aerosol container 11 (to be able to rotate in the directions of arrows B ₁ and B _{2 in} the figure) and mounted. The portion 15 is configured so as not to be easily separated from the aerosol container 11.

Further, an opening 15a formed in the upper part of the mounting portion 15 has two engaging steps 18, 1 opposed to each other.
9 are formed. The engagement steps 18 and 19 are formed over a predetermined range, and therefore,
When viewed from above (FIG. 3 shows the mounting portion 15 as viewed from above), the opening 15a is formed with engagement step portions 18 and 19 projecting inward in a flange shape, Engaging step 1
8 and 19 are not formed (arrows A in FIGS. 2 and 3).
) Is present. Further, a lock protrusion 24 protruding inward is formed at a predetermined position of the engagement step portion 18.

On the other hand, the base section 16 is composed of a nozzle section 20, an operation section 21, and a plate section 22. The nozzle unit 20 and the operation unit 21 are formed above the plate unit 22. The lower end of the nozzle section 20 is connected to a stem 14 attached to the valve 13 and the upper end of the nozzle section 20 is provided with a discharge port 2.
3 are formed. The operation unit 21 is operated when it is desired to take out the contents filled in the aerosol container 11, and the base unit 16 swings by pressing the operation unit 19.

When the contents are to be taken out, the operating section 21 formed on the base 16 is pressed. The base 16 is displaced by pressing the operation unit 21, and accordingly, the nozzle 20 also swings to swing or press the stem 14. As a result, the valve 13 is opened, and the contents filled in the aerosol container 11 are urged by the propellant and discharged from the stem 14, and the discharged contents pass through the nozzle 20 and are discharged from the discharge port. It is discharged from 23 in the form of a foam.

The plate portion 22 constituting the base portion 16 has a disk-like shape.
An engaging flange 25 is provided on the outer peripheral portion on the opposite side via the nozzle portion 20.
Are formed to protrude outward. A joint protrusion 27 is formed at a predetermined position on the outer periphery of the engagement flange 25 (the joint protrusion 27 will be described later in detail). Further, the outer peripheral position of the operation unit 21 is configured to protrude outward by a certain amount from the outer peripheral position of the plate unit 22. In FIG. 1, reference numeral 26 denotes a cap, which is attached to an upper portion of the spout 11 when the aerosol container 11 is carried.

The spout 10 having the above-described structure is mounted on the mounting portion 1.
By rotating the 5 on the aerosol container 11,
The displacement of the base 16 can be locked and unlocked, and the discharge of the contents can be prevented by restricting the displacement of the base 16 in the locked state. Hereinafter, this lock mechanism will be described with reference to FIGS.

FIGS. 3 and 4 show the locked state of the spout 10. In this locked state, the engagement flange 25 formed on the base 16 is engaged with the engagement step 18 formed on the mounting part 15, and the operation part 21 is also formed on the mounting part 15. The other engagement step is engaged with the engagement 19.

Therefore, even when an external force is applied to the base 16, the engagement between the engagement flange 25 and the engagement step 18, and the engagement between the operation section 21 and the engagement step 19, can be achieved. Since the displacement of the base 16 is restricted, the base 16 is not displaced.

Therefore, even if an external force is applied, the base 16 is not displaced, the stem 14 does not swing, and the valve 13 maintains the closed state. Thus, even if the cap 26 comes off when the aerosol container 11 to which the spout 10 according to the present invention is applied is carried in a bag or the like, the contents are reliably prevented from being discharged into the bag. Can be.

On the other hand, when the aerosol container 11 is used,
A position where the engagement flange 25 and the operation portion 21 are separated from the engagement step portions 18 and 19 (a position indicated by an arrow A in FIGS. 2 and 3).
The mounting part 15 is rotated until it is turned. This state is shown in FIGS. As shown in each figure, by rotating the mounting portion 15 over the predetermined angle, the engagement flange 2
The engagement between the engagement step portions 18 and 19 with the operation portion 21 and the operation portion 21 is released, and the attachment portion 15 is configured to be displaceable.

In this state, when the operating portion 21 is pressed, the base portion 16 is displaced downward, whereby the stem 14 is also displaced and the valve 13 is opened. When the valve 13 is opened, the contents filled in the aerosol container 11 are discharged from the stem 14 together with the propellant, and discharged from the discharge port 23 through the nozzle 20 to the outside.

As described above, the lock projection 24 is formed at a predetermined position on the inner periphery of the engaging step portion 18, and the joining protrusion 27 is formed at the outer peripheral position of the engaging flange 25. . The positions where the lock projections 24 and the joint projections 27 are formed are set such that the two 24 and 27 are engaged when the mounting portion 15 is at the lock position described above.

Specifically, when the mounting portion 15 is turned from the unlocked position shown in FIG. 5 toward the locked position (when it is turned in the direction of arrow B in FIG. 5), the lock projection 24 jumps relatively. The joining projections 27 are close to each other,
4, 27 contact. When the mounting portion 15 is further rotated in the direction of arrow B, the joint projection 27 rides over the lock projection 24 and the two 24 and 27 are engaged. In this state, the engaging flange 25 and the engaging step 18 and the operating section 21 and the engaging step 19 are in an engaged state, and the base 16 is in a state where its displacement is regulated. ing.

Therefore, in order to release the above-mentioned locked state, the turning operation must be performed again so that the joining projection 27 gets over the locking projection 24, so that the locked state is released without knowing by an external force or the like. This does not occur, and the discharge of the contents can be prevented. Also, when the spout 10 is in the locked state, the joining projection 27 gets over the locking projection 24,
The user can feel this as a click feeling.
Therefore, the user can detect that the spout 10 has been locked by the click feeling, and the usability is improved.

On the other hand, the above-mentioned joining projection 27 has a function of joining the mounting portion 15 and the base portion 16 when the spout 10 is formed. This will be described with reference to FIG.

FIG. 7 shows the spout 10 immediately after resin molding using a mold. As shown in the figure,
The spout 10 immediately after resin molding has a structure in which the mounting portion 15 and the base portion 16 are joined by joining projections 27 and integrated. Therefore, by providing the joint projection 27, the mounting portion 15 and the base portion 16 can be collectively formed by the same mold, and the cost of the mold and the resulting product cost can be reduced. it can.

The mounting part 15 and the base part 16 integrated as described above are mounted on the aerosol container 11 in this integrated state. At this time, the mounting part 15 is fitted into the upper part of the aerosol container 11, and the base part 16 is fitted into the stem 14. At this time,
Since there is a slight difference between the mounting height of the mounting portion 15 and the mounting height of the base portion 16, a shear force acts on the joining protrusion 27 due to the difference in height, and the joining protrusion 27 The joining protrusion 27 is cut at the joint portion with the mounting portion 15 because of its narrow shape. Thereby, as shown in FIG. 1, the joining protrusion 27 and the mounting portion 15 have a separated and independent structure. Further, since the mounting portion 15 and the base portion 16 can be mounted simultaneously, the assembling work can be easily performed.

In general, the portion where two structures are joined together becomes a so-called burr in the case of resin molding, and it is necessary to remove the burr. However, in the present invention, the mounting portion 1
A portion for joining the base 5 and the base 16 is used as a joining projection 27, and as described above, a function such as confirmation of a locked position is provided. Therefore, the manufacturing process of the spout 10 does not become complicated even with the configuration in which the joining protrusions 27 are provided.
Rather, various benefits such as confirmation of the lock position can be realized.

[0037]

According to the present invention, as described above, the mounting portion and the base portion can be formed integrally, the cost of the mold can be reduced, and the mounting portion and the base portion can be reduced. Can be collectively attached to the aerosol container, so that the assembling work can be simplified. Further, by providing the lock projection, it is possible to confirm that the attachment portion is at the lock position by the connection between the joint and the lock projection. It has such features that it can be recognized with a click feeling generated at the time.
