Description

  The present invention relates to a fixed amount discharge container, and more particularly to a fixed amount discharge container that measures a predetermined amount from a coating liquid stored in a container and discharges the measured coated liquid.

For example, by storing a coating solution such as a hair agent, a cosmetic solution, or a cleaning solution in the container body and devising the structure of the inside plug mounted on the opening of the container body, the amount of discharge of the coating solution can be controlled. A dispensing container is provided.
For example, Patent Document 1 discloses a discharge container in which a spring valve is attached to an opening of a container main body, and an opening amount of the spring valve is controlled according to a pressure applied to an application portion covering the opening. It is disclosed.

According to the discharge container disclosed in Patent Document 1, it is possible to adjust the discharge amount of the coating liquid by properly using the pressing force of the application unit with respect to the portion to be supplied (the application portion).
However, discharge control of the liquid volume by the above-mentioned spring valve is not always stable, and sometimes there is a problem that the usability is poor, such as excessive discharge of the coating liquid more than expected.

In order to solve such a problem, Patent Document 2 discloses a measuring and pouring container capable of pouring out a coating solution measured in advance in a container to a portion to be supplied (a portion to be coated). FIG. 15 shows a side view (in a state in which the cap is tightened) of the measuring and dispensing container disclosed in Patent Document 2 partially in cross section, and FIG. 16 shows a cross-sectional view in a state where the cap is removed.
The measuring and dispensing container 60 shown in FIG. 15 includes a container portion 61 for storing the coating solution, a dispensing unit 62 for dispensing the coating solution contained in the container portion 61, and the dispensing unit 62 so as to cover the dispensing unit 62. And a cap 63 attachable to the container 61.

  As shown in FIG. 16, the pouring unit 62 is fitted inside the upper opening of the container portion 61 and has an elastic valve member 64 whose tip side is formed of an elastic body, and the periphery of the tip side of the elastic valve member 64. The cover is provided so as to cover a cylindrical movable plug 65 which can be opened and closed by advancing and retracting the rear end of the recess inflow hole 64a provided on the rear side of the elastic valve member 64 and the rear side periphery of the movable plug 65. And a shell portion 66 capable of containing a predetermined amount of coating solution. The lower end portion of the shell portion 66 is fitted to the upper opening of the container portion 61 so as to cover the outside thereof.

  The elastic valve member 64 is provided with a fixed piston portion 64b provided on the tip end side from the recessed portion inflow hole 64a, a resin spring portion 64c provided on the tip of the fixed piston portion 64b and expandable in the container axial direction, and a resin spring And a valve portion 64d provided at the tip of the portion 64c. These are covered by the cylindrical movable plug 65 as shown.

  Further, the cylindrical movable plug 65 is movable along the axial direction of the container while the inner peripheral surface is in sliding contact with the outer peripheral surface of the fixed piston portion 64b. Further, an inflow hole 65 a for moving the coating liquid in the shell portion 66 into the movable plug 65 is formed on the side surface of the movable plug 65. The inflow hole 65a is opened and closed by the movement position of the movable plug 65, and in the state of FIG. 11, the closed state is shown.

Further, the tip of the movable plug 65 is exposed to the outside, and an outlet 65b for the coating liquid is formed, and the valve portion 64d can be opened and closed by moving forward and backward with respect to the outlet 65b. A groove 64d1 for pouring out the coating liquid is formed on the side of the valve portion 64d, and the coating liquid is poured out through the groove 64d1 when the pouring port 65b is opened.
Further, as shown in FIG. 15, a rib 63 a that engages with the lip 65 d of the movable plug 65 is provided inside the cap 63.

  In the measuring and dispensing container 60 configured as described above, when the cap 63 is removed from the state where the cap 63 is mounted as shown in FIG. 15, the movable plug 65 is pulled up as shown in FIG. An inflow hole 64 a connecting the container portion 61 and the inside of the shell portion 66 is formed. In this state, when the front end side of the measuring and dispensing container 60 is directed downward, a predetermined amount of coating liquid is supplied into the shell portion 66.

Next, when the front end side of the measuring and pouring container 60 is directed downward and the movable plug 65 is pressed against the portion to be supplied (surface to be coated), the rear end portion of the movable plug 65 as shown in FIG. The inflow hole 64 a is closed, and the content liquid supplied into the shell portion 66 by a predetermined amount is separated from the container portion 61. That is, the coating solution is measured in the shell member 66. When the movable plug 65 is further pushed in, the inflow hole 65 a of the movable plug 65 is opened, and the coating liquid in the shell portion 66 is moved into the movable plug 65. At this time, the valve portion 64 d is in a state in which the outlet 65 b at the tip of the movable plug 65 is closed.
Further, when the projecting valve portion 64d is abutted against the portion to be supplied (surface to be coated) and pushed in, the valve portion 64d is pushed against the movable plug 65 as shown in FIG. 17B, and the groove 64d1 of the valve portion 64d is interposed. The coating solution in the movable plug 65 is then poured out.

However, in the measuring and pouring container 60 disclosed in Patent Document 2, it is necessary to measure the content liquid by pressing the movable plug 65 against the portion to be supplied (the surface to be coated). In order to close the inflow hole 64a to ensure air tightness, a strong load for pushing the movable plug 65 is necessary, and there is a problem that the user feels pain when the supplied portion is a scalp or the like.
In addition, even when the coating liquid is poured out, when the valve portion 64d is pressed against the portion to be supplied (surface to be applied), a relatively strong load is applied because the spring for biasing the valve portion 64d is compressed and pushed. It is necessary, and there is a problem that the user feels pain when the supplied part is a scalp or the like.
Furthermore, since the control of the discharge amount at the time of application is performed by the valve portion 64d supported by the resin spring portion 64c whose load is not stable, the discharge amount may vary and liquid drips.

  The present invention has been made focusing on the above-mentioned point, and in a fixed amount discharge container which measures a predetermined amount from the stored application liquid and discharges the measured application liquid, pain on the application surface felt by the user It is an object of the present invention to provide a fixed discharge container capable of reducing discharge and performing stable discharge without dripping.

In order to solve the problems described above, the fixed amount discharge container according to the present invention covers a liquid container for containing a coating liquid, a discharge unit provided on the tip side thereof, and covers the discharge unit and is attached to and detached from the liquid container. A quantitative discharge container comprising: a cap that can be freely attached; a measuring chamber for containing an application liquid measured from an application liquid in the liquid container; and an application unit that can be filled with the application liquid in the measuring chamber, The discharge unit is in communication with the measuring chamber and has a cylindrical cylinder having at least two through holes disposed so as to be different in axial distance from the tip of the application section, and moves along the axial direction in the cylinder A piston, and at least one of the pair of through holes is closed by the piston, in the axial direction of the piston accompanied by the pressing of the applying portion to the supplied portion. By the backward movement, the opening and closing of the pair of through holes are switched to measure the application liquid in the measurement chamber and to fill the application liquid from the measurement chamber into the application part. .
Further, it is preferable that the application part is formed of a soft member, has a discharge hole, and is deformed by pressing the tip end, and discharge the filled application liquid from the discharge hole. The soft member is preferably a silicone resin.

Further, a piston pressing portion for restricting the backward movement of the piston is provided at the rear of the piston, and by closing the cap, the cylinder and the measuring chamber move rearward, while the piston is the piston The holding portion moves forward relative to the cylinder, is reset to a position before measurement with respect to the cylinder, and enters the measuring chamber from the liquid container side through one of the pair of through holes. It is desirable to be able to fill the coating solution of
Further, the cylinder includes an elastic member for urging the cylinder and the measuring chamber forward, and when the cap is removed, the piston is moved forward together with the cylinder and the measuring chamber by the elastic member to move the piston It is desirable to leave a predetermined distance from the pressing portion.

According to such a configuration, when moving the piston for the first time, the tip of the application portion is pressed against the portion to be supplied with the coating liquid to move the piston, but the portion to be supplied includes a soft member such as silicone resin. Only the load necessary for part deformation and piston sliding is applied. Therefore, the application section can be filled without causing pain to the user. Moreover, also in the case of subsequent use, the user can discharge and use the fixed quantity application liquid in an application part by pressing down an application part, without feeling pain.
In addition, since the application portion is easily deformed, the compressed and deformed portion of the inner surface of the application portion is discharged, and the discharge amount does not vary, so that liquid drip can be prevented.

  According to the present invention, in the fixed amount dispensing container which measures a predetermined amount from the stored application liquid and discharges the measured application liquid, the pain on the application surface felt by the user is reduced and the liquid is stabilized without dripping. It is possible to provide a fixed amount discharge container capable of discharging.
