[0002]

2. Description of the Related Art In a conventional device for applying a liquid hair restorer, for example, when the container body is inverted and the hair restorer is sprinkled on hair under conditions where the outside air temperature is high and the internal pressure of the container body is rising, the hair restorer is not used. There is a drawback that the user squirts directly toward the user, and the user feels discomfort.

[0003] In addition, conventional instruments for applying a liquid have a positive effect of applying the liquid by an additional use mode of irritating and massaging the skin with a brush in addition to the original function of applying the liquid. A device that can be effectively used has also been proposed.

For example, when applying a hair tonic, it is conceivable to incorporate a brush unit having a brush element for stimulating hair roots into an applicator. In this case, it is desirable that the brush unit is retracted inward in the axial direction from the valve body of the valve unit when applying the hair growth material, and that the brush unit is protruded outward in the axial direction from the valve body of the valve unit during hair root stimulation. . When the brush unit is movable between the retracted position and the protruded position of the brush element, the brush unit is positioned with respect to the valve unit at the above two positions, and the user is assured that the positioning is completed. It is desirable to adopt a configuration that can achieve the operational feeling informed of the above. In this respect, further improvement is expected in the conventional hair restorative application device.

[0005]

SUMMARY OF THE INVENTION In view of the above-mentioned prior art, an object of the present invention is to sprinkle a liquid so that the liquid is directed toward a user even when the pressure inside the container increases due to an increase in the outside air temperature. An object of the present invention is to provide a liquid application apparatus having a structure that can effectively prevent ejection and can be used more comfortably.

[0006]

In order to achieve the above object, a liquid application device according to the present invention comprises a container containing a liquid such as a hair restorer, a valve unit mounted on an opening of the container, and a valve unit. And a cover cap removably attached to the container to cover the cover.
The valve unit is coupled to the opening of the container, and has a valve seat formed on the inner peripheral surface of a relatively small-diameter extension having a substantially cylindrical shape, and is elastically pressed against the valve seat. And a valve body. The distal end of the valve body projects from the valve seat member in a closed state pressed against the valve seat, and the valve body separates from the valve seat when the distal end is pushed into the valve seat member. It is arranged to be in the open state. Further, the cover cap has an outer peripheral wall having a substantially cylindrical shape,
It includes a top wall connected to the upper end of the outer peripheral wall, and a hollow cylindrical projection protruding inward in the axial direction from the center of the inner surface of the top wall. When the cover cap is mounted, the outer surface makes sealing contact with the inner peripheral surface of the distal end portion of the valve seat member, and the inner surface contacts the valve body to eccentrically position the valve body with respect to the valve seat. Are arranged in a semi-open state in which a gap is generated between the valve body and the valve seat. When the cover cap is removed from the container while the internal pressure of the container is rising, the internal pressure that has been released to the internal space of the inner peripheral wall in the cover cap through the gap is released while the valve unit is in a semi-open state, and the valve unit is released. In a closed state in which the valve element is positioned coaxially with the valve seat.

According to the above configuration of the present invention, in a semi-open state of the valve unit where a gap is formed between the valve body and the valve seat, the internal pressure of the container is transmitted to the internal space of the projection of the cover cap through this gap. This eliminates the disadvantage that the liquid such as the hair restorer does not spout directly toward the user even under use conditions where the outside air temperature is high, and the user feels discomfort at the start of use.

In the above construction, as a means for eccentricizing the valve body with respect to the valve seat, a projection protruding radially inward is provided on the inner surface of the inner peripheral wall of the cover cap, and the projection is attached to the valve. Preferably, it is accessible to the body.

The distal end of the valve body projects from the valve seat member in a closed state pressed against the valve seat, and the valve body separates from the valve seat when the distal end is pushed into the valve seat member. It is arranged to be in the open state. Also,
The brush unit includes a peripheral wall arranged to face the peripheral wall of the valve unit, and a top wall connected to the upper end of the peripheral wall and having a plurality of brush elements arranged to protrude outward in the axial direction. . An opening is provided at the center of the top wall so as to penetrate the valve seat member of the valve unit. The valve unit of the valve unit projects from the brush element in an axially outward direction. Is mounted on the valve seat member so as to be slidable between a retracted position which is retracted inward in the axial direction of the brush element. Then, at least one guide groove is provided on one of the peripheral wall of the brush unit and the peripheral wall of the valve unit, and at least one protrusion guided by the guide groove is provided on the other, and the guide groove is close to the container. A closed end on the side, an open end on the side remote from the container, and first and second projections provided between the ends. The protrusion is introduced into the guide groove from the open end, and when the brush unit is moved over the first and second protrusions to the closed end, the brush unit is locked at the retracted position, and the protrusion is moved to the second position. The brush unit is positioned at the protruding position when the brush unit is brought into contact with the first projection over the projection, and the brush unit is removed from the valve unit by moving over the first projection to the open end. It is composed.

According to the above configuration of the present invention, two positions of the brush unit with respect to the valve unit, that is, the protrusions are introduced into the guide grooves from the open ends to get over the first and second projections and close to the closed ends. And a brush corresponding to a state in which the brush unit is positioned at the protruding position when the protruding portion goes over the second protrusion and abuts on the first protrusion. It is possible to determine the projecting position of the unit, and to achieve an operational feeling for surely informing the user that the positioning has been completed.

In this case, the guide groove can be formed in a helical shape on the peripheral wall of the brush unit or the valve unit. By forming the groove in a helical shape, the operation required to displace the brush unit between the two positions becomes a rotation operation of the brush unit with respect to the valve unit, and a linear operation when the groove is linear. In contrast, the operability is improved, and the required operating force can be kept low.

Also, one of the peripheral wall of the brush unit and the peripheral wall of the valve unit is provided with the two guide grooves facing each other on the diametrical line, and the other is provided with two projections respectively guided by the guide grooves. be able to. When two pairs of the guide groove and the protrusion are used, the required rotation angle required to align the protrusion with the guide groove is reduced by half, and the operability is improved.

The lower outer surface of the inner peripheral wall 23 comes into sealing contact with the inner peripheral surface of the extension portion 8 of the valve seat member 5 over the entire circumference when the cover cap 4 is attached to the container 1 (see FIGS. 2 and 3). (See FIG. 4). On the lower inner surface of the inner peripheral wall 23, as shown in FIG. 5, a crescent-shaped projection 24 that can come into contact with the outer surface of the valve body 13 is arranged so as to protrude radially inward. The lower end surface of the projection 24 is formed as an inclined guide surface, and guides the valve body 13 when the valve body 13 and the inner peripheral wall 23 are relatively displaced. Note that the height of the outer peripheral wall 21 of the cover cap 4 is such that the brush element 15 is fixed to the top wall of the cover cap 4 even when the brush element 15 of the brush unit 3 is in the protruding position with the cover cap 4 attached to the container. It is desirable that the height be set so as not to contact the inner surface of the first member 21. According to such a configuration, the user can securely attach / detach the cover cap 4 to / from the container 1 regardless of whether the brush unit 3 is at the projecting position or the retracted position with respect to the valve unit 2. It is possible to use the hair-growing agent application device more easily.

When the cover cap 4 is attached to the container 1 (see FIGS. 2 and 3), the inner peripheral wall 23 inside the cover cap 4 has an outer surface formed by the valve seat member 5 on its outer surface as shown by a solid line in FIG. It is in sealing contact with the inner surface of the extension 8. Also, the inner peripheral wall 23 of the cover cap 4
A crescent-shaped projection 24 provided on the inner surface of the valve seat 13 causes the valve body 13 to be eccentric with respect to the valve seat member 5, and a gap exists between the valve seat 9 and the valve body 13. That is, the valve unit 2 is in a semi-open state. Therefore, the air in the container 1 passes through the gap between the valve seat 9 and the valve body 13 and passes through the cover cap 4.
Inner space of the inner peripheral wall 23, that is, the inner peripheral wall 23
, The outer surface of the valve body 13 and the upper surface of the valve seat 9.

On the other hand, when the cover cap 4 is removed from the container 1, the valve body 13 is released from the above-mentioned eccentric state, and is aligned coaxially with the valve seat 9. That is, the valve unit 2 is completely closed. At the same time, the air that has escaped into the inner space of the inner peripheral wall 23 of the cover cap 4 is released to the space between the inner peripheral wall 23 and the outer peripheral wall 21. Thereby, even under conditions where the outside air temperature is high and the internal pressure of the container body 1 is rising, when the container body is inverted and the hair restorer is sprinkled on the hair, the hair restorer directly squirts toward the user. Thus, the problem of discomfort for the user is avoided.

To bring the valve body 13 of the valve unit 2 into contact with the scalp of the user, and press down the container body 1 in this state. By this pressing operation, the valve body 13 is displaced relative to the valve seat 9 toward the container body 1. That is, the original open state of the valve unit 2 in which an annular gap is formed between the valve body 13 and the valve seat 9 is achieved, and the hair restorer can flow toward the scalp and penetrate into the hair root. Further, when the brush unit 3 is in a protruding position with respect to the valve unit 2 as shown in FIG. 3, the scalp can be stimulated by pressing the brush element 15 against the scalp of the user and performing massage. It is possible.

As is clear from the above detailed description,
According to the present invention, when sprinkling a liquid such as a hair tonic, it is possible to effectively prevent the liquid from directly squirting toward the user even when the internal pressure of the container increases due to an increase in the outside air temperature. A liquid application device having a structure that can be used more comfortably is provided. Further, based on a configuration in which a guide groove is provided on one of the peripheral wall of the valve unit and the inner peripheral wall of the cover cap and a projection is provided on the other, two projections corresponding to the retracted position and the projected position of the brush unit are provided. It can be selectively locked in position. As a result, the retracted position and the projected position of the brush unit with respect to the valve unit can be determined, and the user can selectively use the application device at the projected position and the retracted position of the brush unit. Further, an operational feeling for surely informing the user that the positioning operation has been completed is achieved.

The above-described embodiment is merely an example, and does not limit the present invention. It goes without saying that the present invention can be implemented in many forms without departing from the technical scope thereof. For example, a guide groove may be provided on the inner peripheral wall of the cover cap, and a protrusion may be provided on the peripheral wall of the valve unit.
