  However, in the above-described conventional application container, in a state where the valve member is at the application position, the discharge hole that opens to the outside of the container through the inside of the valve member remains open (fully opened state). It was difficult to control the discharge amount of the contents discharged from the container to the outside of the container. For this reason, there is room for improvement in improving the discharge accuracy.

  This invention is made | formed in view of such a situation, Comprising: It aims at providing the application | coating container which can raise the precision of discharge.

In order to solve the above problems, the present invention proposes the following means.
The application container of the present invention is provided with a bottomed cylindrical container main body in which contents to be applied to the application portion are accommodated, and a communication hole that is attached to the mouth of the container main body and communicates with the container main body. A measuring cylinder member in which a measuring chamber communicating with the inside of the container body through the communication hole is formed between the inner plug member and the inner plug member, and a discharge hole communicating with the measuring chamber is formed at the top. And an application plug that is provided in the measurement chamber and has a tip protruding from the discharge hole to the outside of the measurement chamber, the application plug blocking communication between the discharge hole and the measurement chamber. And a measurement position for communicating the measurement chamber and the communication hole, and a position closer to the bottom of the container body along the container axial direction than the measurement position, and the communication between the measurement chamber and the communication hole is blocked. And connecting the discharge hole and the measuring chamber. In a state in which the position of the coating stopper is located at the application position, the gap between the cloth position and the discharge hole is formed through a gap formed between the outer periphery of the application stopper and the discharge hole. The contents can be discharged, and the inner plug member is provided with a support that supports the application plug located at the application position from the bottom side of the container body in the container axial direction. Is supported by the inner plug member so as to be elastically displaceable toward the bottom side of the container main body along the container axial direction, and the bottom side of the container main body along the container axial direction of the application plug located at the application position The end of is supported by the support.

  In the application container of the present invention, the support member of the inner plug member supports the application plug from the bottom side of the container main body along the container axial direction of the application plug with the application plug of the measuring chamber positioned at the application position. It is like that. Then, the tip of the coating plug arranged at the coating position is pressed against the portion to be coated, so that the coating plug and the support body are elastically displaced toward the bottom side of the container body along the container axial direction.

  In other words, according to this coating container, even when the coating plug is located at the coating position, when the tip of the coating plug is pressed against the portion to be coated, the coating plug is elastically displaced together with the support according to the pressing force. Then, it can move toward the bottom side of the container body along the container axial direction.

And when the application plug located in the application position is elastically displaced, for example, a gap is formed between the outer periphery of the application plug and the discharge hole, or formed between the outer periphery of the application plug and the discharge hole. The gap can be further widened. As a result, even when the application plug is in the application position, the discharge hole can be opened and closed (the opening degree is adjusted), and the contents discharged from the measuring chamber to the outside of the container through the discharge hole The discharge amount can be adjusted according to use. Therefore, according to this application container, it is easy to control the discharge amount of the contents discharged from the measurement chamber to the outside of the container through the gap.
That is, desired application (discharge) can be performed with high accuracy by adjusting the number of times and the pressing force with which the tip of the coating plug is pressed against the portion to be coated. Therefore, according to the present invention, the discharge accuracy can be increased.

  Furthermore, when pressing the application plug against the application part such as the scalp or skin of the human body and applying the contents, the impact or external force applied to the application part during the pressing is alleviated by the cushioning action caused by the elastic displacement. In addition to being able to obtain a soft application feeling, it is possible to suppress unpleasantness and uncomfortable feeling and to perform a comfortable and comfortable application.

  Further, the coating stopper located at the coating position is supported by the support at the end on the bottom side of the container body along the container axial direction. Therefore, for example, at the same position along the container axial direction with respect to the end of the coating plug, or at the position of the mouth side (upper side) of the container body along the container axial direction, the coating plug and the inner plug member In this case, the communication between the measuring chamber and the communication hole should be more reliably blocked when the application plug is located at the application position. Can do.

  In the coating container of the present invention, the inner plug member connects the support, a bottomed cylindrical receiving tube disposed in the mouth of the container main body, and the support and the receiving tube. And an elastic piece that can be elastically deformed, and the support body abuts the bottom wall of the receiving tube from the mouth side of the container body along the container axial direction in a state of being elastically displaced. It is good also as providing a base.

According to the above configuration, when the tip of the coating plug is pressed against the portion to be coated with the coating plug positioned at the coating position and supported by the support, the elastic piece of the inner plug member receives the pressing force. Accordingly, the application stopper and the support body are elastically displaced toward the bottom side of the container body along the container axial direction with respect to the receiving tube.
Then, the base part of the support body that has been elastically displaced comes into contact with the bottom wall of the receiving tube from the mouth side of the container body along the container axial direction, so that the coating plug and the support body further exceed the container body. It is prevented from being elastically displaced toward the bottom side of the. Thereby, it is possible to prevent the elastic piece from being elastically deformed excessively, to maintain its function stably, and to obtain the above-described effects of the present invention more stably.

  Moreover, the application container of this invention WHEREIN: The said support body is good also as providing the support part which supports the said application | coating stopper located in the said application | coating position from the bottom part side of the said container main body along the container axial direction.

  According to the above configuration, since the application plug positioned at the application position is supported by the support portion of the support, the posture of the application plug is stable, and the container axial direction and radial position with respect to the inner plug member of the application plug Can be stabilized. Thereby, for example, in a state where the tip of the application plug located at the application position is pressed (elastically displaced), the flow path cross-sectional area between the discharge hole and the application plug is stabilized, and the contents are applied. The amount can be stabilized, or the communication between the measuring chamber and the communication hole can be reliably blocked.

  Further, in the application container of the present invention, the application plug is provided with a stopper protrusion protruding outward in the radial direction, and when the application plug is located at the measurement position, the stopper protrusion protrudes from the measuring tube. It is good also as being able to contact | abut from the bottom part side of the said container main body along a container axial direction with respect to the opening peripheral part of the said discharge hole of a member.

  According to the above configuration, it is possible to prevent the coating stopper located at the measuring position from being discharged from the discharge hole to the outside of the container (outside the measuring chamber).

  According to the application container of the present invention, it is possible to improve the discharge accuracy.

The gap is zero (in a state where it is not pressed against S), and the discharge hole 8 and the measuring chamber 6 are in communication with each other while being disconnected. From this state, the coating plug 9 and the support 11 are elastically displaced as described above, whereby the gap is generated (increased) and the discharge hole 8 and the measuring chamber 6 communicate with each other.

  In the example shown in the drawing, the outer peripheral surface of the upper cylindrical portion 26 has a lower end with the largest diameter, and a portion other than the lower end is formed with a small diameter. Further, the lower end portion of the upper cylindrical portion 26 is gradually reduced in diameter as it goes upward. Thereby, as described above, when the elastic piece 28 is elastically deformed and the support 11 and the application plug 9 are moved downward relative to the measuring cylinder member 7, the outer peripheral surface of the upper cylinder part 26 and the discharge cylinder part The gap between the inner peripheral surface 19 (discharge hole 8) and the inner peripheral surface 19 is widened, so that a larger cross-sectional area of the content is secured.

  In addition, an annular or arcuate protrusion 26 a that protrudes radially outward and extends along the circumferential direction is formed on the upper end portion of the outer peripheral surface of the upper cylindrical portion 26. In the illustrated example, the thickness of the upper cylinder part 26 is thicker than the thicknesses of the lower cylinder part 24 and the guide cylinder part 25.

In FIG. 2, the overcap 10 has an outer cap 29 and an inner cap 30 accommodated in the outer cap 29.
The outer cap 29 has a top tube shape.
The inner cap 30 has a crest-like shape, and projects from the top wall 30a, the peripheral wall 30b that gradually increases in diameter toward the lower side from the top wall 30a, and radially outward from the lower end of the peripheral wall 30b. And an annular flange portion 30c extending in the circumferential direction.

  The top wall 30a of the inner cap 30 is in contact with the top wall of the outer cap 29 from below. Further, on the top wall 30 a of the inner cap 30, a lifting cylinder 31 inserted from the upper side between the discharge cylinder part 19 of the measuring cylinder member 7 and the upper cylinder part 26 of the application plug 9 is suspended. Yes. As shown in the right side portion of the container shaft O in FIG. 2, the outer peripheral surface of the lifting cylinder 31 is radially inward of the discharge cylinder portion 19 with the overcap 10 attached to the mouth portion 3 of the container body 2. Is fitted.

  Further, an annular or arcuate protrusion 31 a that protrudes radially inward and extends along the circumferential direction is formed on the inner peripheral surface of the lifting cylinder 31. As shown in the right side portion of the container shaft O in FIG. 2, the protrusion 31 a of the lifting cylinder 31 is formed on the upper cylinder portion 26 of the application plug 9 in the state where the overcap 10 is attached to the mouth portion 3 of the container body 2. It faces the protrusion 26a from below.

  Further, when the overcap 10 moves upward with respect to the coating plug 9, the projection 31 a of the pulling cylinder 31 is locked from the lower side with respect to the projection 26 a of the coating plug 9 and is more than a predetermined amount. When the external force is applied, the projection 26a can be climbed upward.

  Specifically, as shown in the left part of the container axis O in FIG. 2, when the overcap 10 is removed from the mouth 3 of the container body 2, the protrusion 31 a of the lifting cylinder 31 is below the protrusion 26 a of the coating plug 9. When the overcap 10 is further moved upward from this locked state, the coating stopper 9 locked to the lifting cylinder 31 is pulled up, and the coating position is moved to the measuring position. Moving.

  When the application plug 9 is moved to the measuring position, the stopper projection 24c of the application plug 9 comes into contact with the top wall (opening peripheral edge portion of the discharge hole 8) of the connecting cylinder portion 20 of the measurement cylinder member 7, thereby The application plug 9 is restricted from rising beyond the measuring position. From this state, when the overcap 10 further moves upward with respect to the mouth 3 of the container body 2, the protrusion 31a of the lifting cylinder 31 gets over the protrusion 26a of the coating plug 9 upward, The overcap 10 is removed from the application plug 9.

On the other hand, when the overcap 10 is attached to the mouth portion 3 of the container body 2, the protrusion 31a of the lifting cylinder 31 is brought into contact with the protrusion 26a of the coating plug 9 from the upper side and locked. When the overcap 10 moves downward, when the application plug 9 is located at the measurement position, the overcap 10 is pushed down to the application position.
Then, when the lower end opening edge of the guide tube portion 25 of the coating plug 9 is supported by being in contact with the support portion 11b of the support body 11 from above, the overcap 10 is further moved downward. Then, the elastic piece 28 is elastically deformed to move the coating plug 9 and the support 11 downward, and the base 11c of the support 11 comes into contact with the bottom wall 12a of the receiving cylinder 12 from above, thereby applying the coating. Further downward movement of the stopper 9 and the support 11 is restricted. When the overcap 10 further moves downward from this state, the protrusion 31a of the lifting cylinder 31 gets over the protrusion 26a of the coating stopper 9 downward, and in the right part of the container shaft O in FIG. It will be in the state shown. In the illustrated example, the tip of the application plug 9 (the tip of the upper cylindrical portion 26) is in contact with the top wall 30a of the inner cap 30 from below in this state.

  The peripheral wall 30b of the inner cap 30 is formed corresponding to the shape of the outer peripheral surface of the measuring cylinder member 7 and the mouth portion 3 of the container body 2, and has a small diameter that gradually increases from the top wall 30a downward. It has a cylinder part, a medium diameter cylinder part, and a large diameter cylinder part. The middle diameter cylindrical portion and the large diameter cylindrical portion of the peripheral wall 30b each have a top cylindrical shape including an annular top wall and a peripheral wall. In the example shown in the right side portion of the container shaft O in FIG. The top wall of the large-diameter cylinder part is in contact with the top wall of the mounting cylinder part 18 from above. Further, an internal thread portion that is screwed to the external thread portion of the mouth portion 3 is formed on the inner peripheral surface of the large-diameter cylindrical portion of the peripheral wall 30b.

The outer peripheral edge portion of the flange portion 30 c is in contact with the inner peripheral surface of the outer cap 29. The flange portion 30 c is located above the lower end opening edge of the outer cap 29.
A stepped portion 32 having a wall surface facing the circumferential direction is formed at a connecting portion between the radially inner end of the flange portion 30c of the inner cap 30 and the lower end portion of the peripheral wall 30b, and the overcap 10 is a container. When mounted on the mouth 3 of the main body 2, the stepped portion 32 can be brought into contact with the detent rib 3 b of the container main body 2 from the circumferential direction.

  In order to apply the contents to the application portion S using the application container 1 of the present embodiment described above, first, the overcap 10 is removed from the mouth 3 of the container body 2, and the discharge hole 8 and the application plug 9 are removed. The tip of is exposed outside the container. Here, when the overcap 10 is removed, the application plug 9 in the measurement chamber 6 is pulled up and moved from the application position to the measurement position.

  Next, in a state where the application plug 9 is disposed at the measurement position, the application container 1 is turned upside down to allow the contents to flow into the measurement chamber 6. From this state, as shown in FIG. 3, the tip of the coating plug 9 is pressed against the portion to be coated S, and the coating plug 9 is moved to the coating position, so that it is shown on the left side portion of the container shaft O in FIG. As shown, the communication between the measuring chamber 6 and the communication hole 5 is blocked, and the gap between the outer periphery of the application plug 9 and the inner periphery (discharge hole 8) of the discharge cylinder portion 19 is substantially sealed (this inverted posture). In FIG. 5, when the application plug 9 is not elastically displaced, the content is sealed to such an extent that the content does not flow out of the gap, and a predetermined amount of content is measured in the measuring chamber 6. And this application | coating container 1 will be in the state which can apply | coat the content through between the discharge hole 8 and the front-end | tip (upper cylinder part 26) of the application | coating plug 9, and by pressing the front-end | tip of this application | coating plug 9 against the to-be-coated part S, etc. A predetermined amount of contents are applied.

  Here, in a state where the application plug 9 of the measuring chamber 6 is located at the application position, the support 11 of the inner plug member 4 supports the application plug 9 from the lower side of the application plug 9. . Then, the tip of the application plug 9 arranged at the application position is pressed against the application portion S, so that the application plug 9 and the support body 11 are elastically deformed in the container axis O direction by the elastic piece 28 being elastically deformed. The container body 2 is elastically displaced toward the bottom side (the lower side defined in the present specification, the upper side in FIG. 3).

  That is, according to this application container 1, even when the application plug 9 is located at the application position, when the tip of the application plug 9 is pressed against the application portion S, the application plug 9 and the support 11 are subjected to the pressing force. Accordingly, it can move toward the bottom side of the container body 2 along the container axis O direction by being elastically displaced accordingly.

When the application plug 9 located at the application position is elastically displaced, for example, a gap is formed between the outer periphery of the application plug 9 and the discharge hole 8, or between the outer periphery of the application plug 9 and the discharge hole 8. The gap formed between them can be further widened. This makes it possible to open and close (adjust the opening degree) the discharge hole 8 even when the application plug 9 is located at the application position, and discharge from the measuring chamber 6 to the outside of the container through the discharge hole 8. The amount of discharged contents can be adjusted according to use. In this embodiment, the application plug 9 is elastically displaced, so that the gap formed between the outer periphery of the application plug 9 and the discharge hole 8 is further widened so that the cross-sectional area of the gap is increased. It is configured.
Therefore, according to this application container 1, it is easy to control the discharge amount of the contents discharged from the inside of the measurement chamber 6 to the outside of the container through the gap.
That is, desired application (discharge) can be performed with high accuracy by adjusting the number of times and the pressing force with which the tip of the application plug 9 is pressed against the application portion S. Therefore, according to this embodiment, the accuracy of ejection can be improved.

  Further, when the application plug 9 is pressed against the application portion S such as the scalp or skin of the human body and the contents are applied, the impact, external force, etc. exerted on the application portion S during the pressing are caused by the cushion action due to the elastic displacement. It is alleviated and a soft application feeling can be obtained, and the feeling of discomfort and uncomfortableness can be suppressed, and a comfortable and comfortable application can be performed.

  Further, the coating stopper 9 located at the coating position has a lower end portion (the end portion on the bottom side of the container main body along the container axis O direction, specifically, the lower end opening edge of the guide tube portion 25) at the support body 11. Has come to be supported. Therefore, as described in the present embodiment, the application plug 9 and the inner plug member are located at the same position along the vertical direction with respect to the lower end portion (guide tube portion 25) of the application plug 9 or at a position above the upper position. 4 (the peripheral wall of the receiving cylinder 12) can be configured to block the communication hole 5, and the communication between the measuring chamber 6 and the communication hole 5 when the coating plug 9 is located at the coating position is blocked. Can be made more reliable.

That is, according to the above configuration, when the tip of the coating plug 9 is pressed against the coated portion S in a state where the coating plug 9 is positioned at the coating position and supported by the support 11, the elasticity of the inner plug member 4. When the piece 28 is elastically deformed according to the pressing force, the coating plug 9 and the support 11 are elastically displaced toward the bottom side of the container body 2 along the container axis O with respect to the receiving cylinder 12.
Then, the base 11c of the support 11 that is elastically displaced comes into contact with the bottom wall 12a of the receiving cylinder 12 from the side of the mouth 3 of the container body 2 along the container axis O direction, The support 11 is prevented from being elastically displaced further toward the bottom side of the container body 2.

Moreover, since the support body 11 is provided with the support part 11b which supports the application | coating stopper 9 located in the said application | coating position from the bottom part side of the container main body 2 along the container axis | shaft O direction, there exists the following effect.
That is, according to the above configuration, since the application plug 9 located at the application position is supported by the support portion 11b of the support 11, the posture of the application plug 9 is stabilized, and the container with respect to the inner plug member 4 of the application plug 9 is stable. It is possible to stabilize the position in the axis O direction and the radial direction. As a result, for example, in a state where the tip of the application plug 9 located at the application position is pressed (elastically displaced), the flow path cross-sectional area between the discharge hole 8 and the application plug 9 is stabilized and the contents are stabilized. The application amount of the object can be stabilized, or the communication between the measuring chamber 6 and the communication hole 5 can be reliably blocked.

Further, a stopper projection 24c is provided on the plug body 22 of the coating plug 9 so as to project outward in the radial direction. The stopper projection 24c is configured so that when the coating plug 9 is positioned at the measurement position, the measuring cylinder member 7 can be brought into contact with the peripheral edge of the opening of the discharge hole 8 from the bottom side of the container body 2 along the container axis O direction.
That is, according to the above configuration, the application plug 9 positioned at the measurement position is prevented from coming out from the discharge hole 8 to the outside of the container (outside the measurement chamber 6).
