  However, since the application part and the massage part are integrated, it is very difficult to perform an operation when only massage is desired without supplying the application liquid.

In view of such circumstances, the present invention provides a liquid applicator with a massage function that can be easily applied and massaged independently.

The present invention relates to a liquid applicator with a massage function having a shaft cylinder that stores liquid and an application portion that is attached to the tip of the shaft cylinder.
The application part has an application core made of a fiber core or a porous body (sintered core ) for supplying a liquid, and a tip shaft provided with a massage part made of resin ,
The application core and the massage part are both arranged on the distal end side of the applicator, and each is configured separately, and the outer peripheral wall behind the massage part on the front shaft has a helical elastic deformation A liquid applicator with a massage function, characterized in that a part is formed and a resilient force is applied to the massage part by the elastic deformation part .

In the present invention, the massage part and the coating core are supported by being elastically repelled relative to the shaft tube, and the elastic force toward the tip of the massage part is the elastic force toward the tip of the coating core. together they make lower than the central portion of the massaging portion is exposed coated core to form a through hole, a plurality of protrusions are protruding shaped exposed from the distal end surface, front barrel preferably be integrally formed It is.

  Further, in the present invention, it is preferable that a helical elastic deformation portion is formed on the outer peripheral wall of the front shaft behind the massage portion, and the elastic deformation portion provides a resilient force to the massage portion. It is.

  In the present invention, the coating core is surrounded by the elastic deformation portion of the front shaft and is mounted so as to be able to advance and retract from the opening at the tip of the massage portion, and between the rear portion of the coating core and the shaft cylinder Is provided with a valve mechanism for bringing the liquid in the shaft cylinder into a non-leading state to the coating core, and passes through the coating core when the coating core is pressed and the valve mechanism is opened. It is preferable that the liquid is supplied to the tip of the coating core.

  The tip shaft is formed such that the elastic deformation portion is formed in a substantially spiral shape so as to be elastically deformable, and the massage portion, the elastic deformation portion, and the mounting portion to the shaft cylinder are integrally molded with resin. Is preferred.

According to the applicator with a massage function of the present invention, it is easy to switch between massage and application by separating the application part and the massage part.
In addition, the elastic force toward the tip of the massage part is lower than the elastic force toward the tip of the application core, so that the load that can move to the rear of the massage part is behind the application core from which the liquid discharges. Since the coating core does not move backward with a light load when the application portion is pressed against the target portion, only the massage can be performed, and further pressing allows the coating core to move backward. If the valve is opened by moving the application core backward, the application state is established, and switching between massage and application can be facilitated.

A cap 30 is provided for fitting with the tip of the rear shaft 10 to prevent the coating core 14 from volatilizing.

  When the applicator is not used, as shown in FIG. 1, the cap 30 is fitted on the outer diameter portion of the tip shaft 18 to prevent volatilization due to the exposure of the applicator core 14 and the massage portion 16, and when the applicator is used. As shown in FIG. 2, the cap 30 is removed to expose the coating core 14 and the massage portion 16. The cap 30 is formed into a bottomed cylindrical body using a synthetic resin made of PP or the like.

[Rear axle 10]
The rear shaft 10 is a cylindrical container whose rear end is closed, and a coating liquid is accommodated in the rear shaft 10. The rear portion of the front shaft 18 is fixed to the front end portion 10a of the rear shaft 10 by screwing.

  The rear shaft 10 is formed into a bottomed cylindrical body using, for example, a synthetic resin made of PP or the like, and functions as an applicator main body. The entire rear shaft 10 and the front shaft 18 are formed to be opaque or transparent (and translucent), but any of them may be adopted from the viewpoint of appearance and practical use. Further, the front shaft 18 is fixed to the outer peripheral portion of the tip portion 10a that is opened in a cylindrical shape of the rear shaft 10 by press fitting or the like.

FIG. 2 is a view showing a liquid applicator with a massage function with the cap 30 removed.
The massage part 16 and the coating core 14 of the front shaft 18 are ejected and supported so as to be movable back and forth with respect to the front shaft 18.

  The massage portion 16 of the tip shaft 18 is formed with a plurality of massage projections 16a protruding from the tip of the tip shaft 18, and the tip of the coating core 14 is exposed from the through hole 16b in the middle (center) thereof. It is desirable that the distal end surface of the massage projection 16 a is exposed from the distal end surface of the coating core 14. In use, after the front shaft 18 is compressed in the axial direction, the coating core 14 moves in the axial direction, so that the valve mechanism 28 opens, and the liquid in the rear shaft 10 can flow out toward the coating core 14. Become.

  At that time, only the front shaft 18 is compressed (the elastic deformation portion 32 is compressed and deformed, and the valve mechanism 28 is not opened), so that only the massage can be performed without discharging the liquid.

  The coating core 14 is inserted into the hollow of the joint 20 so as to be movable back and forth, and the rear end of the coating core 14 operates the valve mechanism 28.

  FIG. 3 is a view showing the liquid container with the front shaft 18 removed. As in this state, it is possible to apply a liquid without the tip 18 but it is not possible to massage. The tip of the coating core 14 protrudes from the joint 20.

[Fitting 20]
As shown in FIG. 4, the joint 20 has a substantially cylindrical shape, and the rear end portion has a larger diameter than the front end portion, and a flange is provided around the large diameter. As shown in FIG. 1, the rear end portion of the joint 20 is fitted into the opening at the front end of the rear shaft 10 via the valve seat 24 of the valve mechanism 28.

  As shown in FIG. 4, a flow path 20a into which the coating core 14 can be inserted is provided at the center of the joint 20, and a plurality of grooves are formed on the inner surface of the flow path 20a. By forming the groove, even when the flow rate from the coating core 14 is insufficient, the liquid can be supplied from the groove, so that an appropriate liquid flow rate can be secured. The joint 20 is molded using a synthetic resin made of PP or the like.

[Lead shaft 18]
2 and 5, the front shaft 18 is formed in a substantially cylindrical shape, and the massage portion 16 has a ring shape at the tip, and a plurality of massage protrusions 16 a are exposed and formed from the tip surface. Yes.

  Further, in the massage part 16, an application core exposed part including a through hole 16 b is formed in the center part where the massage protrusions 16 a are arranged in an annular shape, and the application core 14 is exposed when the massage core 16 is attached to the rear shaft 10 of the liquid container. It is supposed to be.

  A substantially spiral elastic deformation portion 32 is formed in the outer peripheral portion of the side surface of the front shaft 18 and provided with a space portion that penetrates the spiral inside and outside in order to obtain a spring force (spring load). It is desirable that the elastic force of the elastically deforming portion 32 be lower than the elastic force of the coating core 14 in preparation for performing only massage by the protrusion 16a.

  A fitting portion 18b with the rear shaft 10 is formed on the inner surface of the mounting portion 18a provided at the rear portion of the front shaft 18. Note that the fitting portion 18b is not limited to the annular protrusion, and there is no particular problem as long as the fitting method is a structure that does not easily come off the rear shaft, such as screwing or press fitting with a screw.

  The tip shaft 18 is formed by resin-molding, for example, polypropylene (PP), with the massage portion 16 at the tip thereof integrally with the mounting portion 18a via the elastic deformation portion 32.

[Valve mechanism 28]
In the applicator, as shown in FIGS. 2 and 6, the application core 14 is mounted so as to be able to move forward and backward from the through hole 16 b at the tip of the massage portion 16, surrounded by the elastic deformation portion 32 of the tip shaft 18. Has been.

  Between the rear part of the coating core 14 and the inside of the rear shaft 10, a valve mechanism 28 for bringing the liquid in the rear shaft 10 into the coating core 14 and in a non-leading state is provided.

  In the valve mechanism 28, as shown in FIGS. 2 and 3, a rear center hole 24a of a roughly mortar-shaped valve seat 24 is provided so that a valve rod 22 having a coating core 14 inserted into the rear portion of the joint 20 can be moved forward and backward. The valve rod 22 is ejected toward the front by a spring 26. The valve rod 22 and the valve seat 24 of the valve mechanism 28 are made of polyethylene (PE).

  An O (O) ring 34 is interposed between the rear surface of the valve seat 24 and the front end surface of the rear shaft 10 (front end portion 10a) to maintain watertightness.

  Also, a sealing portion (indicated by reference numeral 36 in FIG. 2) where the shoulder portion of the valve stem 22 with a taper opening at the rear and the corner portion of the valve seat 24 whose diameter is increased in the rearward direction abuts is provided. The seal portion 36 is closed in a state in which it is urged forward, and the seal portion 36 is opened when the valve rod 22 moves rearward against the urging force of the spring 26.

  Further, the rear end portion of the valve rod 22 is inserted into the central hole 24a at the rear end of the valve seat 24, and the central hole 24a is closed by the rearward movement of the valve rod 22 more than a predetermined amount.

  According to the applicator with a massage function of this embodiment, when the tip of the application part 12 is pressed against the target surface, the elastic deformation part of the front shaft 18 is elastically deformed, and the application core 14 is pushed backward. Then, as shown in FIG. 6, when the coating core 14 is pressed to open the valve mechanism 28 and the valve mechanism 28 is opened, the coating core 14 itself and the coating core 14 and the joint 20 are connected. The coating liquid (liquid) is supplied to the tip of the coating core 14 through the flow path 20a provided in the gap.

  Accordingly, since the valve mechanism 28 is opened at the same time as the application core 14 is pressed and the application liquid is applied, the user presses the application core 14 and presses the valve mechanism 28 when the application unit 12 is pressed against the target portion. Therefore, an appropriate amount of coating solution can be supplied to the coated surface for convenient use.

  In addition, the elasticity of the massage part 16 toward the front is lower than the elasticity of the application core 14 toward the front. That is, the load capable of moving the massage portion 16 backward is set lower than the load capable of moving the coating core 14 that discharges the liquid backward.

Therefore, when the user holds the applicator and presses the applicator 12 against the target part such as the scalp, the following state occurs.
(1) In the applicator, when a relatively light load is applied to the application part 12, the protrusion 16a of the massage part 16 and the application core 14 of the application part 12 hit the target part, and the elastic deformation part 32 is elastically deformed. It is assumed that the spring 26 of the mechanism 28 is not deformed. In this state, since the coating core 14 does not move backward, the valve mechanism 28 is not opened and the coating solution is not supplied to the coating core 14, while the protrusion 16 a of the massage unit 16 abuts on the target part such as the scalp. Only the target area can be massaged sufficiently.

(2) Further, when a relatively heavy load is applied to the application part 12, the application part 12 is pushed in and the application core 14 is pressed by the target part and moves backward. Since the valve mechanism 28 is opened by the rearward movement of the coating core 14, the coating liquid is supplied to the coating core 14 to be in a coating state.

  From the above, it is possible to easily switch between massage and application by adjusting the pressing force. Therefore, as a pen-type applicator that is easy to grasp, it is possible to massage at the same time while applying the application liquid by pressing it in a timely manner.

  For example, if the applicator of the present invention is a pen-shaped hair growth agent container, the valve mechanism 28 is opened by pressing the application part against the scalp, and the application liquid drops. The massage unit 16 repels with an appropriate force in accordance with the movement of the valve mechanism 28.

  The applicator of the present invention is a mechanism of an applicator with a massage function having a structure in which a coating liquid is dropped and a structure in which a massage instrument is integrated. Cost benefits can also be expected with a simple mechanism using some of the existing parts. In addition, it is a pen type that is easy to grip, and it is possible to massage at the same time while dripping the contents liquid.

  The present invention is not limited to the above embodiment, and various other modifications can be implemented. For example, although the massage part and the elastically deforming part are integrally molded with the front shaft, the front shaft can be formed as a separate body and assembled into a single part. At that time, the material can be formed of a metal material other than the resin material or the like with an appropriate material as required.

  The applicator with a massage function of the present invention can be used for scalp cosmetics, hair restorers, and skin drugs.
