Description

  The present invention relates to a fixed amount discharge container capable of discharging a fixed amount of a coating liquid each time an application portion disposed in an opening of a container body is pressed against a supply location.

  For example, it is possible to control the discharge amount of the coating liquid by storing the coating liquid such as hair preparation, cosmetic liquid, or cleaning liquid in the container body and devising the structure of the inner plug attached to the opening of the container body. Discharge containers are provided.

For example, Patent Document 1 discloses a discharge container in which a spring valve is attached to an opening of a container body, and the amount of opening of the spring valve is controlled according to the pressure applied to an application part that covers 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 against the supply location (application portion).
However, the above-described discharge control of the amount of liquid by the spring valve is not always stable, and there is a problem that it is not easy to use, such as sometimes causing excessive discharge of the coating liquid.

Therefore, Patent Document 2 discloses a discharge container in which a measuring container is formed in an inner plug portion attached to an opening of a container body, and a coating liquid contained in the measuring container can be discharged by a predetermined operation. It is disclosed.
That is, in the discharge container disclosed in Patent Document 2, the container body in the upright posture is turned upside down, the coating liquid is filled in the measurement container, and the container body is put in the upright posture again to measure the container. It is necessary to move the inner coating liquid into another reservoir and remove the cap covering the opening in this state. And by making the container main body into the inverted posture again, the coating liquid moved to the storage section can be discharged from the coating section arranged so as to cover the opening.

Therefore, according to the discharge container disclosed in Patent Document 2, a series of operations for discharging a fixed amount of coating liquid is extremely complicated, and the measuring container and the coating liquid in the measuring container are placed on the inner plug portion. A structure including another storage unit to be moved is required.
Thus, it is necessary to provide an extremely complicated mechanism in the inner plug portion, which increases the number of parts of the entire discharge container, and inevitably increases the manufacturing cost of the discharge container.

Therefore, the present invention has been made to solve the problems of the conventional discharge containers described above, and the object thereof is to simplify the structure and reduce the manufacturing cost, and to discharge the coating liquid. Is to provide a metered discharge container which can be easily achieved.
In addition, the opening of the container body is provided with a coating portion made of a soft elastic material, and a fixed amount of coating liquid can be continuously discharged for each operation by a unique pump action by the pressing operation of the coating portion. It is an object of the present invention to provide a fixed amount discharge container.

The metering discharge container according to the present invention, which has been made to solve the above-mentioned problems, has a container body in which an opening is formed at the upper end of the body part and the coating liquid is stored in the body part in an upright posture, The cylinder body is attached in a state where the opening of the container body is closed, and is configured to be elastically deformable in the axial direction of the opening, and a cylindrical cylinder is formed along the axial direction inside the cylinder. An application member made of a soft elastic material that forms a discharge part that communicates with the inside of the discharge liquid and discharges the application liquid to the outside, and is disposed below the cylinder part in the upright posture , and the application member is in the axial direction And a piston member that closes the coating liquid flow path between the cylinder portion and discharges the coating liquid in the cylinder portion to the outside through the discharge portion when elastically deformed. In a state that is not subjected to deformation in the axial direction, the cylinder part and the piston member are separated from each other, and the coating liquid in the container body can be supplied into the cylinder part in the inverted posture of the container body, The piston member has a cylindrical outer peripheral surface along the axial direction, and is disposed in a cylindrical body portion that is attached to the opening of the container body via a support rib and an annular surface connected to the cylindrical body portion. An annular abutting portion is formed on the lower bottom portion of the cylinder portion inside the application member, and the annular abutting portion is formed when the pressure applied by the pressing operation is applied to the application member. It abuts on the surface.

In this case, preferably, the piston member is disposed in a cylindrical body portion attached to the opening of the container body via a support rib connected to the cylindrical body portion, and the cylindrical body portion, the support rib, and the piston. A configuration in which the member is integrally formed of a resin material to constitute the inner plug member is employed.
And in one preferable example, the said application member is attached in the state which obstruct | occluded the opening part of the container main body via the said cylinder part which comprises the said inside plug member.
In addition, it is desirable that the entire application member is formed of a soft elastic material such as silicon rubber, urethane resin, or thermoplastic elastomer.

  According to the quantitative discharge container having the above-described configuration, the coating member that covers the opening of the container body is made of a soft elastic material, and a discharge section that discharges the coating liquid to the outside is formed. Then, the application member can be deformed in the axial direction of the opening by pressing the tip of the application member against the supply location (applied part), and thereby the cylinder part and the piston member arranged inside As a result, a certain amount of coating liquid can be discharged from the discharge portion.

Therefore, in an example in which a hair preparation is contained as an application liquid in the container body, an appropriate massage effect can be given to the scalp by placing the container body in an inverted posture and pressing the application member against the scalp. .
And since a fixed amount of coating liquid can be discharged by the pumping action of the cylinder part and the piston member for each pressing operation of the coating member, an appropriate amount corresponding to the number of times the coating member is pressed It becomes possible to supply the hair preparation to the scalp.

It is the perspective view which showed the whole structure of the fixed discharge container which concerns on this invention. It is the longitudinal cross-sectional view of the center part. It is the top view which expanded and showed the inner stopper member with which the opening part of a container main body is mounted | worn. It is sectional drawing of the inner stopper member seen from the AA line in FIG. 3 in the arrow direction. It is an expanded sectional view of the application member which covers the opening of a container main part. It is an expanded sectional view of the application member which shows the state elastically deformed by pressing an application member against an application part.

A quantitative discharge container according to the present invention will be described based on an embodiment shown in the drawings. In the drawings shown below, the same parts are indicated by the same reference numerals. However, in some drawings, the representative parts are indicated by reference numerals for the sake of space, and the detailed configuration is shown in other drawings. In some cases, the reference numerals attached to are used for reference.
In the following, description will be made on the basis of an example in which a hair preparation is stored as a coating liquid in a fixed discharge container and a fixed quantity of hair preparation can be supplied to the scalp.

FIG. 1 and FIG. 2 show an overall configuration of a constant-volume discharge container. A constant-rate discharge container 1 shown in this example includes a container body 2 in which a coating liquid (hair preparation) is stored, and an opening of the container body 2. And a coating member 4 made of a soft elastic material that covers the opening of the container body 2.
An O-ring 5 is attached to the inner plug member 3, and the inner plug member 3 is attached to the opening of the container body 2 in a liquid-tight state by the O-ring 5.

  The container body 2 is formed of a synthetic resin such as polypropylene resin, and includes a cylindrical body 2b having a bottom 2a as shown in FIGS. 1 and 2, and the upper side of the body 2b is formed to have a slightly small diameter. An annular opening 2c is formed at the end. That is, the container body 2 is in an upright posture, and the coating liquid (hair preparation) is stored in the body portion 2b.

The inner plug member 3 is attached to the opening 2c of the container body 2 as described above.
The single-piece structure of the inner plug member 3 is shown in an enlarged state in FIGS. 3 and 4, and the inner plug member 3 is mounted in the opening 2 c of the container main body 2, so that the inner plug member 3 is attached to the container main body 2. A cylindrical body 3a attached in a fitted state is provided.
On the upper end portion side of the cylindrical body portion 3a, an outer diameter is formed to be slightly narrow, and a cylindrical surface 3b for mounting the application member 4 is formed. Then, on the inner side of the upper end portion of the cylindrical surface 3b, a piston member 3c having a cylindrical outer peripheral surface along the axial direction is attached concentrically with the cylindrical body portion 3a via a support rib 3d. ing.

In this embodiment, the piston member 3c is attached via three support ribs 3d that are radially formed with an interval of 120 degrees on the inner peripheral surface of the cylindrical portion 3a as shown in FIG. The cylindrical portion 3a, the support rib 3d, and the piston member 3c are integrally formed of a resin material to constitute the inner plug member 3.
Therefore, when the fixed discharge container 1 is turned upside down, the coating liquid can be caused to flow into the coating member 4 through the arc-shaped gap formed between the three support ribs 3d.

As shown in FIGS. 3 and 4, the inner plug member 3 is formed with an annular horizontal surface 3e (also referred to as an annular surface 3e) so as to surround the bottom of the piston member 3c . The horizontal surface 3e functions as a stopper for preventing the application member 4 from being deformed in the axial direction beyond a predetermined level, as will be described later.
Reference numeral 3f applied to the inner plug member 3 is an annular groove for mounting the O-ring 4. The reference numeral 3g contacts the annular opening 2c of the container body 2, and the container body 2 is a flange that performs positioning of the inner plug member 3 with respect to 2. Reference numeral 3h denotes an overhang portion that prevents the application member 4 from being detached from the inner plug member 3 by mounting the proximal end portion of the application member 4.

5 and 6 are enlarged sectional views of the coating member 4 attached so as to cover the opening 2c of the container body 2 via the inner plug member 3, and FIG. 5 is subjected to deformation in the axial direction. FIG. 6 shows a state in which the applying member 4 is elastically deformed by receiving a pressing force indicated by a white arrow.
In addition, as above-mentioned, this application | coating member 4 is comprised with the soft elastic material as a whole, Preferably it is comprised with soft elastic materials, such as a silicone rubber, a urethane resin, or a thermoplastic elastomer.

The application member 4 has a base end portion 4a formed in a cylindrical shape and is attached to the overhang portion 3g and the cylindrical surface 3b of the inner plug member 3 so that the opening of the container main body 2 is opened via the inner plug member 3. The part 2c is attached in a closed state. The central portion of the application member 4 in the axial direction is formed in a conical shape to form a thin portion 4b, and the upper end portion is formed in a slightly thick state in the axial direction, and the top surface as the application surface 4c is formed in a flat shape.
Further, a cylindrical cylinder portion 4d is formed inside the coating member 4 along the axial direction, and a discharge portion 4e that communicates with the inside of the cylinder portion 4d and discharges the coating liquid to the outside is formed. . In this example, a small-diameter hole as the discharge portion 4e is formed in a state of penetrating the center portion of the top surface 4c.

Further, following the cylinder portion 4d, a tapered surface 4f whose inner diameter increases toward the container body 2 side is formed, and a lower bottom portion provided with the tapered surface 4f constitutes an annular contact portion 4g. ing.
As shown in FIG. 6, the annular contact portion 4 g is formed in the inner plug member 3 when pressure is applied by a pressing operation indicated by a white arrow on the top surface 4 c of the application member 4. It contacts the annular surface 3e that functions as a stopper, and acts to prevent the coating member 4 from being deformed beyond a predetermined level.

Thus, the quantitative discharge container 1 having the above-described configuration is used in a state where the application member 4 is turned downward by inverting the upright posture shown in FIGS. 1 and 2 to the inverted posture.
When the fixed discharge container 1 is in an inverted posture, the coating liquid stored in the container body 2 arrives immediately after the discharge part 4 e in the coating member 4. However, since the discharge part 4e has a small diameter hole with a diameter of 0.6 to 1.4 mm formed in a portion that is slightly thickened in the axial direction, it can be applied by the surface tension of the coating liquid. It is possible to prevent the liquid from leaking out of the discharge part 4e and so-called dripping.

Then, with the application member 4 facing downward, the top surface 4c of the application member 4 is pressed against the scalp, so that the conical thin portion 4b formed on the application member 4 is as shown in FIG. Bends and undergoes deformation in the axial direction.
Thereby, the piston member 3c formed in the inner plug member 3 enters relatively to the cylinder portion 4b formed in the application member 4. At this time, the tapered surface 4f following the cylinder portion 4d functions as a guide so that the piston member 3c surely enters the cylinder portion 4b.
Then, the pressure in the cylinder part 4b increases, but the gap between the cylinder part 4b and the piston member 3c becomes extremely narrow, so that the coating liquid (hair agent) is unlikely to flow out of the gap between the cylinder part 4b and the piston member 3c. The flow path between the portion 4b and the piston member 3c is almost closed.

Accordingly, the coating liquid (hair preparation) in the cylinder portion 4b is relatively pushed by the piston member 3c and discharged from the discharge portion 4e to the top surface 4c side.
The discharge amount of the coating liquid at this time corresponds to the volume inside the cylinder part 4b, and a fixed amount of the coating liquid is discharged from the discharge part 4e of the coating member 4 for each pressing operation of the coating member 4. Will be.

  Therefore, the top surface 4c of the application member 4 formed of a soft elastic material can give an appropriate massage effect to the scalp, and an appropriate amount of hair according to the number of times the application member 4 is pressed. Can be supplied to the scalp, and the effects as described in the above-mentioned column of the effect of the invention can be obtained.
