Description

  The present invention relates to a liquid application container.

  As this type of liquid application container, a configuration is known in which a liquid contained in a container main body is applied to an object little by little by pressing an application body against the object (see, for example, Patent Document 1).

Japanese Utility Model Publication No. 4-41875

  However, in the conventional liquid application container, for example, when the container main body is held by hand, the inside of the container main body is heated by the heat of the hand, and as a result, in the initial stage of applying the liquid, A large amount of liquid may be unintentionally discharged from the discharge hole. This tendency is particularly strong when the liquid contained in the container body is a highly volatile liquid. For example, when the liquid is an athlete's foot drug, nail polish, or pedicure, if the liquid is unintentionally discharged in large quantities, the liquid may adhere to the skin other than the nail that is the object.

  Then, an object of this invention is to provide the liquid application container which suppressed that a large amount of liquids were not discharged unintentionally.

  The present invention employs the following means in order to solve the above problems. That is, the liquid application container of the present invention is a liquid application container that applies a liquid to the object by pressing an application body that is inserted into the discharge hole so as to be able to appear and disappear, and a container body that stores the liquid; The inside of the container body communicates with the discharge hole formed in the top wall portion, and the top has a top-coated tubular application plug body that houses the application body, and the application body faces the discharge hole. Energizing and causing the tip of the application body to protrude outside from the top wall through the discharge hole, and the outer peripheral surface of the base end portion on the base end side to contact the inner peripheral surface of the coating plug body And a coating plug mechanism having an urging member for blocking the flow path to the discharge hole, and a communication hole for communicating the inside of the container main body and the inside of the coating plug main body inside the liquid coating container An inside plug in which is formed is provided.

In this invention, for example, when the communication hole is filled with the liquid due to the surface tension of the liquid or the like, the communication between the container body and the coating plug body is blocked. Thereby, even if the air in the container body is heated by the heat of the hand holding the container body, the heat is prevented from being transmitted into the coating plug body, and a large amount due to the heating in the coating plug body Liquid ejection can be suppressed.
In addition, when the liquid application container is tilted, for example, the liquid in the container body does not reach the discharge hole directly, and the flow is hindered by the inner plug. Can be prevented from being discharged.
Therefore, it is possible to prevent a large amount of liquid from being unintentionally discharged from the discharge holes and to apply an appropriate amount of liquid.

In the liquid application container of the present invention, the opening peripheral edge of the communication hole on the surface of the inner plug facing the discharge hole side is gradually separated from the discharge hole side toward the communication hole side. It may be inclined to face.
In this invention, when the liquid in the container main body flows into the coating plug main body, it becomes possible to flow on the inclined surface of the opening peripheral edge portion of the communication hole on the surface facing the discharge hole side of the inner plug. As a result, the liquid that has passed through the communication hole does not drop toward the discharge hole, but easily flows toward the discharge hole along the inner peripheral surface of the coating plug body, and a large amount of liquid is discharged from the discharge hole. Can be suppressed more reliably.

  According to the liquid application container according to the present invention, even if the air in the container body is heated by the heat of the hand holding the container body by filling the communication hole with the liquid, the heat is applied in the application plug body. In addition to suppressing the transmission, the liquid in the container body is less likely to flow into the application plug body when the liquid application container is gripped and tilted, so a large amount of liquid is unintentionally discharged from the discharge hole. This can be suppressed.

The lower surface of the top wall portion 11A extends gradually downward from the radially inner side to the outer side, forming a first cylinder inclined surface 11B. Note that the inner diameter of the tip cylindrical portion 11 excluding the top wall portion 11A is substantially the same in the vertical direction.

The inner peripheral surface of the upper end portion of the intermediate cylinder portion 12 gradually increases in diameter as it goes downward, forming a second cylinder inclined surface 12A.

The application body 21 is arranged coaxially with the central axis O, and a columnar tip portion 23 and a conical bowl-shaped base end portion 24 opening downward are arranged in this order from the upper side to the lower side. Has been configured. The distal end portion 23 and the proximal end portion 24 are disposed coaxially with the central axis O.

The tip portion 23 is constituted by a columnar small diameter portion 25 and a columnar large diameter portion 26 that are arranged in this order from the upper side to the lower side, and the small diameter portion 25 and the large diameter portion 26 are arranged at the center. It is arranged coaxially with the axis O.
The small-diameter portion 25 is inserted into the minute hole 3A, and the upper end portion of the small-diameter portion 25 has a conical shape that protrudes upward, and extends upward from the top surface of the top wall portion 11A of the distal end cylindrical portion 11. Protruding. Moreover, the outer diameter in the part below the said upper end part among the small diameter parts 25 is substantially the same over the full length of an up-down direction. Further, a gap is formed between the outer peripheral surface of the small diameter portion 25 and the inner peripheral surface of the minute hole 3A of the top wall portion 11A. In addition, it is only necessary that the liquid can flow through between the outer peripheral surface of the small diameter portion 25 and the inner peripheral surface of the minute hole 3A of the top wall portion 11A.

The outer diameter of the large-diameter portion 26 is larger than that of the small-diameter portion 25, and is substantially the same over the entire length in the vertical direction except for the upper end portion. Further, the length in the vertical direction of the large diameter portion 26 is substantially the same as the length in the vertical direction in the portion of the tip tube portion 11 excluding the top wall portion 11A. Furthermore, the outer peripheral surface of the large diameter portion 26 and the inner peripheral surface of the intermediate cylinder portion 12 are close to each other over the entire vertical direction, and a gap is formed between them. Note that it is sufficient that the liquid can flow between the outer peripheral surface of the large diameter portion 26 and the inner peripheral surface of the intermediate cylinder portion 12, and the large diameter portion 26 is in contact with the inner peripheral surface of the intermediate cylinder portion 12. Also good.
Moreover, the outer peripheral surface in the upper end part of the large diameter part 26 is gradually diameter-expanded as it goes below, and forms 26 A of 1st stopper | inclination surfaces. The first plug inclined surface 26A faces the first tube inclined surface 11B in the up-down direction. The first plug inclined surface 26A may be in contact with the first tube inclined surface 11B, or a gap may be provided between the first plug inclined surface 11B and the first tube inclined surface 11B.
The length in the vertical direction of the large-diameter portion 26 is longer than the protruding length L of the tip portion 23 with respect to the top wall portion 11A of the coating plug body 3.

  The base end portion 24 is connected to the lower end of the large-diameter portion 26, and the inner diameter and the outer diameter gradually increase from the upper side to the lower side. And the outer peripheral surface of the base end part 24 forms the 2nd stopper inclined surface 24A, and contacts the 2nd cylinder inclined surface 12A of the intermediate | middle cylinder part 12, and the flow path R (refer FIG. 3) to 3 A of micropores ). The inclination angles of the second plug inclined surface 24A and the second tube inclined surface 12A with respect to the central axis O are the same as the inclination angles of the first plug inclined surface 26A and the first tube inclined surface 11B. Further, in the longitudinal sectional view, the second plug inclined surface 24A and the second tube inclined surface 12A are longer than the first plug inclined surface 26A and the first tube inclined surface 11B.

  The urging body 22 is a spring formed of, for example, a resin material, and the upper end is fixed to the lower end of the application body 21, and the lower end has an annular shape in a plan view and is fitted in the proximal end cylindrical portion 13. The fixing ring 27 is fixed to the proximal end cylinder portion 13. The urging body 22 constantly urges the applicator 21 upward, and in an unloaded state, the upper end of the small diameter portion 25 of the applicator 21 protrudes upward from the applicator plug body 3 and the applicator plug body 3 By making the two-cylinder inclined surface 12A and the second stopper inclined surface 24A of the application body 21 contact each other, the flow path to the minute hole 3A is blocked.

  As shown in FIGS. 1 and 2, the inner plug 5 is fitted in the proximal end cylinder portion 13 of the coating plug main body 3. The outer peripheral edge portion of the inner plug 5 protrudes in the vertical direction from the center portion, and the upper surface of the outer peripheral edge portion of the inner plug 5 is in contact with the lower surface of the fixing ring 27. A communication hole 5 </ b> A that allows the inside of the container main body 2 and the inside of the coating plug main body 3 to communicate with each other is formed at the center of the inner plug 5. The diameter of the communication hole 5A is, for example, not less than 8 mm and not more than 20 mm, but is not limited thereto. Note that the shape of the communication hole 5A is appropriately set according to, for example, the surface tension, viscosity, and volatility of the liquid. Depending on the properties of the liquid, the liquid can remain in the communication hole 5A and block the communication hole 5A. It has become.

The opening peripheral part of the communication hole 5A on the upper surface of the inner plug 5 is inclined so as to gradually go downward as it goes radially inward, and the opening peripheral part of the communication hole 5A on the lower surface of the inner plug 5 is also the same. Inclined so as to gradually go upward as it goes radially inward. The inner plug 5 is vertically symmetric with respect to the cross section in the middle portion in the vertical direction. Thereby, when attaching the inside plug 5 in the application | coating stopper main body 3, it is not necessary to match | combine the direction of the up-down direction of the inside plug 5, and attachment of the inside plug 5 becomes easy.
The communication hole 5A has a smaller diameter than the minute hole 3A, but may have a larger diameter or the same diameter as the minute hole 3A depending on the properties of the liquid such as the viscosity and volatilization temperature of the liquid.

Next, a liquid discharge method using the liquid application container 1 having the above configuration will be described.
Here, when the liquid application container 1 is tilted so that the minute hole 3A faces downward, for example, in an inverted posture, when the liquid is discharged or transported at least once, the liquid in the container body 2 passes through the communication hole 5A. And flows into the coating plug body 3. When the liquid application container 1 is returned to the upright posture, the liquid flowing into the application plug body 3 returns to the container body 2, but a part of the liquid is plugged due to the viscosity or surface tension of the liquid. 5 communication holes 5A are closed. Thereby, the communication between the container body 2 and the coating plug body 3 is blocked.

In this state, when the container body 2 is held by hand and the liquid application container 1 is in an inverted posture, for example, the air in the container body 2 is heated by the heat of the hand. However, since the communication hole 5A is blocked by the liquid and the communication between the container body 2 and the coating plug body 3 is blocked, the heat of the hand is not easily transmitted to the coating plug body 3. ing. Thereby, it is suppressed that the air and the liquid in the coating stopper main body 3 are heated.
Therefore, even if the air or liquid in the container body 2 is heated by the heat of the hand, the liquid or air in the coating plug body 3 is suppressed from being heated and the internal pressure of the coating plug body 3 is increased. It is difficult for the liquid in the coating plug body 3 to be pushed out toward the minute holes 3A. In addition, since the liquid in the coating plug body 3 is heated to prevent the liquid from volatilizing or changing physical properties such as viscosity, the liquid in the coating plug body 3 vigorously moves toward the micro holes 3A. It is difficult to flow well.

  Further, by setting the liquid application container 1 in an inverted position while holding the container body 2 by hand, the internal pressure of the container body 2 is such that the liquid in the container body 2 is heated and the viscosity decreases or volatilizes. It rises when the air in the container body 2 is heated. As a result, the liquid that has blocked the communication hole 5A flows into the coating plug body 3 to open the communication hole 5A, and the liquid in the container body 2 passes through the communication hole 5A and enters the coating plug body 3. Inflow. The liquid that has flowed into the coating plug body 3 flows along the upper surface of the inner plug 5 toward the inner peripheral surface of the coating plug body 3. Here, since the opening peripheral edge of the communication hole 5A on the upper surface of the inner plug 5 is inclined downward toward the inner side in the radial direction, the liquid is applied along the inclined surface on the upper surface of the inner plug 5. It is guided smoothly toward the inner peripheral surface of the stopper main body 3 and flows toward the minute holes 3 </ b> A along the inner peripheral surface of the coating stopper main body 3.

When the small-diameter portion 25 of the application body 21 is pressed against the object while holding the container body 2, the small-diameter portion 25 of the application body 21 resists the urging force of the urging body 22 as shown in FIG. 3. Then, it moves downward to the inside of the coating plug main body 3 so as to be submerged from the minute hole 3A. Then, the second plug inclined surface 24A of the application body 21 is separated from the second cylinder inclined surface 12A of the application plug body 3, and the flow path P to the minute hole 3A is opened.
Here, as described above, even if the container body 2 is held by hand, the increase in the pressure of the coating plug body 3 is suppressed, so that at the initial stage when the flow path P is opened, the liquid is microporous. Unintentional discharge from 3A is suppressed.

In a state in which the flow path P is opened, the flow path P includes the gap P1 formed between the lower end portion of the large diameter portion 26 and the upper end portion of the intermediate cylinder portion 12, and the upper end of the large diameter portion 26 of the application body 21. A gap P2 formed between the lower end portion of the distal end cylindrical portion 11 of the coating plug main body 3 and a gap P3 formed between the lower end portion of the small diameter portion 25 and the distal end cylindrical portion 11, and the small diameter portion 25. Is formed by a gap P4 between the upper end portion of the first cylindrical portion 11 and the top wall portion 11A of the distal end cylindrical portion 11. Here, the gaps P2 and P4 are narrower than the gaps P3 and P4.
Here, the application body 21 is pushed into the application plug body 3 so that the upper end of the small-diameter portion 25 of the application body 21 and the top surface of the top wall portion 11A of the application plug body 3 are flush with each other. The lower end edge of the first plug inclined surface 26 </ b> A is positioned above the upper end edge of the second cylinder inclined surface 12 </ b> A of the intermediate cylinder portion 12 in the coating plug main body 3.

  The liquid that has flowed into the flow path P flows upward and radially inward along the second cylinder inclined surface 12A of the application plug body 3 in the gap P1, and the outer peripheral surface of the large-diameter portion 26 of the application body 21. (Region Z1). Then, the liquid flows into the gap P3 through the gap P2, and collides with the lower surface of the top wall portion 11A of the coating plug main body 3 in the gap P3 (region Z2). Furthermore, the liquid flows upward and radially inward along the first cylinder inclined surface 11B of the top wall portion 11A, and collides with the outer peripheral surface of the small diameter portion 25 of the application body 21 (region Z3). Thereafter, the liquid is discharged to the outside through the micro hole 3A through the gap P4.

Moreover, by setting the liquid application container 1 in the inverted posture, the liquid in the container main body 2 sequentially flows into the application plug main body 3 through the communication hole 5A.
Here, the inner plug 5 divides the inside of the liquid application container 1 into the container main body 2 side and the application plug main body 3 side. Since the inner plug 5 functions as a baffle plate, the liquid in the container main body 2 is It is difficult to vigorously flow into the coating plug body 3. Further, only one communication hole 5 </ b> A is formed in the inner plug 5, and the liquid in the container main body 2 is less likely to flow into the coating plug main body 3 vigorously because air replacement is less likely to occur. Yes.
The liquid is discharged as described above.
In addition, although the liquid is discharged in a state where the liquid application container 1 is in the inverted posture, the liquid may be discharged in another posture such as tilting without being in the inverted posture.

As described above, according to the liquid application container 1 according to the present embodiment, when the communication hole 5A is filled with the liquid, the inner plug 5 blocks and holds the communication between the container body 2 and the application plug body 3. Since the air and liquid in the coating plug body 3 are not easily heated by the heat of the hand, a large amount of liquid is unintentionally discharged from the micro holes 3A due to the heating in the coating plug body 3. Can be suppressed.
In addition, when the liquid application container 1 is turned upside down, the inner plug 5 prevents the liquid in the container main body 2 from flowing into the application plug main body 3. Can be prevented from being discharged.
Further, when the liquid application container 1 is in the inverted posture, the liquid that has passed through the communication hole 5A is not dropped toward the minute hole 3A, but is flowed toward the minute hole 3A along the inner peripheral surface of the application stopper main body 3. Since it becomes easy, it can suppress more reliably that a lot of liquids are discharged from 3A of micropores.

In addition, this invention is not limited to the said embodiment, A various change can be added in the range which does not deviate from the meaning of this invention.
For example, the opening peripheral edge of the communication hole on the upper surface of the inner plug is inclined so as to gradually go downward as it goes radially inward, but it does not have to be so inclined. Further, the inner plug is vertically symmetric with respect to the transverse line in the middle portion in the vertical direction, but it may not be vertically symmetric.
The inner stopper is attached in the proximal end cylinder portion of the coating stopper main body, but may be attached in the container main body. Further, the inner plug may be formed integrally with another member.
Although only one communication hole is formed in the inner plug, a plurality of communication holes may be formed.
The application body has a cylindrical shape, but may have other shapes such as a prismatic shape. Similarly, the applicator plug body has a crested cylindrical shape, but may have other shapes such as a crested rectangular tube shape.
The outer peripheral surface of the upper end portion of the large-diameter portion of the application body and the lower surface of the top wall portion of the distal end tubular portion of the application plug body are inclined so as to gradually increase in diameter toward the lower side, but are not inclined. Also good.
Although the urging body urges the application body upward, it may be urged in a direction inclined with respect to the central axis of the liquid application container. Similarly, the liquid application container discharges the liquid upward, but the liquid application container may discharge the liquid in a direction inclined with respect to the central axis of the liquid application container.

  According to the present invention, industrial applicability is recognized for a liquid application container that suppresses unintentional discharge of a large amount of liquid.
