Japanese Patent No. 5229542

  However, in the conventional application container, when the tip of the application plug located at the application position is brought into contact with the application part, a large amount of contents may unexpectedly flow out from the discharge hole to the application part. .

  This invention is made | formed in view of the situation mentioned above, Comprising: It aims at suppressing a large amount of contents flowing out from a discharge hole to a to-be-coated part unexpectedly.

In order to solve the above problems, the present invention proposes the following means.
The application container according to the present invention has a bottomed cylindrical container main body in which contents to be applied to the application target part 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 tube in which a measuring chamber communicating with the inside of the container body through the communication hole is formed between the inner plug member formed and the inner plug member, and a discharge hole communicating with the measuring chamber is formed at the top. And a coating plug provided at the measuring chamber and having a tip protruding from the discharge hole to the outside of the measuring chamber. The coating plug communicates with the discharge hole and the measuring chamber. A measuring position that blocks and connects the measuring chamber and the communication hole, and is positioned closer to the bottom of the container body along the container axial direction than the measuring position, and communicates between the measuring chamber and the communication hole. And the discharge hole is connected to the weighing chamber. Between the application position and the application position to be moved in the container axial direction, and when the application plug is positioned at the application position on the outer peripheral surface of the application plug, Guide protrusions that are in contact with or close to each other are formed, and at least one of the inner peripheral surface of the discharge hole and the guide protrusions, the application plug is located at the application position, and the measurement chamber is directed to the outside of the container. A communication groove through which the contents can be distributed is formed.

According to the present invention, when the coating plug is positioned at the coating position, the guide projection is formed on the outer circumferential surface of the coating plug so as to come into contact with or close to the inner circumferential surface of the ejection hole. Since the communication groove is formed in at least one of the guide protrusions, the flow path is narrowed by passing through the communication groove before the contents of the measurement chamber are discharged from the discharge hole to the application portion, It is possible to increase the flow resistance, and it is possible to suppress a large amount of contents from flowing out of the discharge hole to the application portion.
In addition, when the application plug is located at the application position, the guide protrusion is in contact with or close to the inner peripheral surface of the discharge hole in the radial direction, so that the application plug is attached to the measuring tube member at the application position. On the other hand, even if an external force for shifting the position in the radial direction is applied, the guide protrusion can be brought into contact with the inner peripheral surface of the discharge hole in the radial direction. Therefore, it is possible to prevent the coating plug from being inclined with respect to the measuring cylinder member when the tip of the coating plug located at the coating position is brought into contact with the coated portion, and a large amount of contents are unexpectedly generated. It is possible to reliably suppress the outflow from the discharge hole to the application portion.

  Here, the application plug includes a fitting portion that is fitted into the discharge hole when positioned at the metering position, and the guide protrusion is connected to the fitting portion from above the fitting portion. It may be arranged.

  In this case, since the guide protrusion is arranged continuously from above the fitting portion to the fitting portion fitted into the discharge hole when the application plug is located at the measurement position, the guide projection is located at the measurement position. With the application plug, the communication between the discharge hole and the measuring chamber can be reliably blocked.

  The communication groove may be formed on the guide protrusion and open upward.

  In this case, the communication groove is formed on the guide protrusion and is opened upward, so that the flow path of the contents from the measuring chamber to the outside of the container is stabilized with the application plug positioned at the application position. Can be secured.

  In addition, the communication groove is formed on the inner peripheral surface of the discharge hole, and the lower end is opened downward, and the upper end of the communication groove is the guide protrusion in a state where the application plug is located at the application position. It may be located above the upper end of the outer peripheral surface.

  In this case, the communication groove is formed on the inner peripheral surface of the discharge hole, the lower end is opened downward, and the upper end of the communication groove is located on the outer peripheral surface of the guide projection with the application plug positioned at the application position. Since it is located above the upper end, it is possible to stably secure a flow path for contents from the measuring chamber to the outside of the container in a state where the application plug is located at the application position.

It has a connection cylinder part 20 which is located between the part 18 and the top part 19, and connects these 18,19.
In the illustrated example, the diameter of the measuring cylinder member 7 is gradually reduced from the lower side toward the upper side in the order of the mounting cylinder part 18, the connecting cylinder part 20, and the top part 19.

  The mounting cylinder portion 18 has a top cylinder shape having an annular ceiling wall and a peripheral wall. The peripheral wall of the mounting cylinder part 18 is externally fitted to the upper end part of the mouth part 3 of the container body 2 and the outer fitting cylinder 17 of the inner plug member 4.

The top portion 19 is formed in a cylindrical shape and protrudes upward from the inner peripheral edge portion of the top wall of the connecting tube portion 20. Note that the top portion 19 may be formed in, for example, a rectangular tube shape. Further, the inner peripheral edge of the annular top wall of the connecting cylinder part 20 may be used as the discharge hole 8 without providing the top part 19. That is, the top of the measuring cylinder member 7 may be the top wall of the connecting cylinder part 20.
In the present embodiment, the space defined by the connecting tube portion 20 of the measuring tube member 7 and the main fitting tube 13 of the inner plug member 4 is the measuring chamber 6. That is, the inner peripheral surface of the measuring chamber 6 is constituted by the inner peripheral surface of the main fitting tube 13 of the inner plug member 4 and the inner peripheral surface of the peripheral wall of the connecting tube portion 20 of the measuring tube member 7.

The application plug 9 blocks the communication between the discharge hole 8 and the measurement chamber 6 and connects the measurement chamber 6 and the communication hole 5 (for example, the state shown in FIG. 3), and below the measurement position ( It is located on the bottom side of the container main body along the container axial direction, blocks communication between the measurement chamber 6 and the communication hole 5, and allows the discharge hole 8 and the measurement chamber 6 to communicate (here, "to communicate"). Means that it includes both the meanings of “communicating or enabling communication”) between the application position (for example, the state shown in FIGS. 1, 2, and 5) and the container axis O direction (vertical direction). ) Is movably disposed.
In the illustrated example, the contents in the measuring chamber 6 can be discharged through the gap between the outer peripheral surface of the application plug 9 and the inner peripheral surface of the discharge hole 8 with the application plug 9 positioned at the application position. Yes.

  The coating plug 9 extends downward from the top wall of the sealing cylinder 24 disposed in the measuring cylinder member 7 and from the top wall of the sealing cylinder 24, and is surrounded from the outside in the radial direction by the peripheral wall of the sealing cylinder 24. And the cylindrical tip portion 26 erected on the top wall of the seal cylinder 24. The seal cylinder 24, the extrapolation cylinder 25, and the distal end portion 26 are arranged coaxially with the container axis O and are integrally formed.

As shown in FIG. 3, the upper portion of the seal cylinder 24 is slidably fitted inside the discharge hole 8 when the application plug 9 is located at the measurement position, and the communication between the discharge hole 8 and the measurement chamber 6 is established. The fitting part 24b which interrupts | blocks is provided. The fitting portion 24b is the entire area excluding the upper end portion in the upper portion of the seal cylinder 24. The lower end portion of the seal cylinder 24 is slidably fitted inside the cylinder cylinder 12 when the application plug 9 is positioned at the application position as shown in FIGS. In the illustrated example, the thickness of the lower end portion of the seal cylinder 24 is thinner than the thickness of other portions.
When such a lower end portion of the seal cylinder 24 is located at the application position, the lower end of the seal cylinder 24 is fitted into the cylinder cylinder 12 to block communication between the measurement chamber 6 and the communication hole 5, while when positioned at the measurement position, The measurement chamber 6 and the communication hole 5 are communicated with each other by detaching upward from the cylinder cylinder 12.

  The application plug 9 includes a stopper step 24c that protrudes outward in the radial direction. The stopper step portion 24 c is formed at an intermediate portion in the container axis O direction on the outer peripheral surface of the seal cylinder 24. The stopper step portion 24c is arranged continuously from the lower portion of the fitting portion 24b to the fitting portion 24b. The stopper step 24c is formed in an annular shape extending along the circumferential direction. As shown in FIG. 3, the stopper step portion 24 c can come into contact with the peripheral edge portion of the discharge hole 8 in the measuring cylinder member 7 from below when the application plug 9 is positioned at the measuring position. . In the illustrated example, the stopper step portion 24 c can be brought into contact with the inner peripheral edge portion of the top wall of the connecting tube portion 20 of the measuring tube member 7 from below.

In a state where the application plug 9 is located at the measurement position, the stopper step 24c of the application plug 9 abuts the peripheral edge of the discharge hole 8 in the measurement cylinder member 7 from below, so that Even when an external force is applied to move the applicator plug 9 upward, the applicator cap 9 positioned at the measuring position is restricted from moving further upward.
Here, an annular or arcuate first engagement protrusion 24a is formed on the outer peripheral surface of the upper portion of the seal cylinder 24 so as to protrude outward in the radial direction and extend in the circumferential direction. The first engagement protrusion 24a is disposed at a connection portion between a guide protrusion 21 and a fitting part 24b, which will be described later. The first engagement protrusion 24a climbs upward over the second engagement protrusion 8a formed on the inner peripheral surface of the discharge hole 8 when the application plug 9 moves from the application position to the metering position. The engaging protrusion 8a is engaged from below the first engaging protrusion 24a. In addition, the 1st engagement protrusion 24a and the 2nd engagement protrusion 8a do not need to mutually engage over a perimeter.

  The outer insertion cylinder 25 is inserted on the guide shaft 11a of the inner plug member 4 so as to be movable up and down. In the illustrated example, the extrapolation cylinder 25 moves up and down in a non-contact state with the guide shaft 11 a of the inner plug member 4. Thereby, the coating stopper 9 can be moved up and down smoothly. Further, the lower end opening edge of the extrapolation cylinder 25 is located below the lower end opening edge of the seal cylinder 24.

  As shown in FIG. 2, the lower end opening edge of the outer insertion tube 25 is in contact with the upper end edge of the restriction portion 11 b of the support body 11 in a state where the application plug 9 is located at the application position, and the restriction portion 11 b of the support body 11. Is supported from below. At this time, a gap in the container axis O direction is provided between the upper end edge of the guide shaft 11 a of the support 11 and the top wall of the seal cylinder 24. Instead of this, the upper end edge of the guide shaft 11a and the top wall of the seal cylinder 24 may be brought into contact with each other to restrict further downward movement of the coating plug 9.

With the application plug 9 positioned at the application position, the distal end portion 26 of the application plug 9 is disposed in the top portion 19 of the measuring cylinder member 7. The outer diameter of the tip portion 26 is smaller than the outer diameter of the fitting portion 24b. A gap through which the contents can flow is provided between the outer peripheral surface of the distal end portion 26 and the inner peripheral surface of the discharge hole 8 in a state where the application plug 9 is located at the application position.
An annular or arcuate engaged portion 26 a that protrudes inward in the radial direction and extends in the circumferential direction is formed on the inner peripheral surface of the upper end portion of the distal end portion 26.

The application container 1 includes a cap body 10 that is detachably attached to the mouth portion 3 of the container body 2 and covers the discharge hole 8 and the distal end portion 26 of the application plug 9.
The cap body 10 has a top tube shape, and 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 lower portion of the peripheral wall. The female thread portion may be, for example, a double thread.
Instead of the cap body 10 being detachably screwed to the mouth portion 3, for example, the smooth outer peripheral surface of the mouth portion 3 is detachably fitted to the smooth inner peripheral surface of the cap body 10. Or, the cap body 10 may be appropriately changed such that the cap body 10 is detachably fitted into the mouth portion 3. Further, instead of attaching the cap body 10 to the mouth portion 3, for example, the cap body 10 may be attached to the measuring cylinder member 7.

  The top wall of the cap body 10 is formed with a lifting cylinder 31 that protrudes downward and has a lower end portion detachably fitted in the distal end portion 26 of the application plug 9 located at the application position. . On the outer peripheral surface of the lifting cylinder 31, an annular or arc-shaped lifting protrusion 31 a that protrudes outward in the radial direction and extends in the circumferential direction is formed. The lifting protrusion 31 a is undercut fitted to the engaged portion 26 a of the distal end portion 26 of the application plug 9. As the cap body 10 moves upward with respect to the mouth portion 3 and the measuring cylinder member 7, the application plug 9 is moved. Pulled up and moved from the application position to the weighing position.

Here, when the lifting protrusion 31 a of the cap body 10 is disengaged from the engaged portion 26 a of the application plug 9, the stopper step portion 24 c of the application plug 9 positioned at the measurement position is the opening of the discharge hole 8 in the measurement cylinder member 7. By abutting the peripheral edge from the lower side, the movement of the coating plug 9 further upward is restricted. Therefore, when the lifting protrusion 31a of the cap body 10 is disengaged from the engaged portion 26a of the coating plug 9, an elastic repulsive force directed downward is generated in the coating plug 9.
However, as described above, the first engagement protrusion 24a of the application plug 9 is engaged with the second engagement protrusion 8a of the measuring cylinder member 7 from below the first engagement protrusion 24a. Therefore, the downward movement of the coating plug 9 from the measuring position can be restricted.

The top wall of the cap body 10 is formed with an external fitting cylinder 28 that protrudes downward and is detachably fitted to the top portion 19 of the measuring cylinder member 7.
The cap body 10 includes a contact portion 27 that contacts the top portion 19 of the measuring cylinder member 7 from above. The contact portion 27 protrudes downward from the top wall of the cap body 10. The abutting portion 27 is disposed on a portion of the top wall of the cap body 10 that is located inside the outer fitting tube 28. A plurality of contact portions 27 are arranged at intervals in the circumferential direction, and are formed integrally with the inner peripheral surface of the outer fitting tube 28. The lower end edge of the contact part 27 is located above the lower end opening edge of the external fitting cylinder 28. The lower end edge of the contact portion 27 is in contact with the upper end opening edge of the top portion 19 of the measuring cylinder member 7. The contact portion 27 may be formed in an annular shape.

  On the inner peripheral surface of the cap body 10, a step portion 32 having a wall surface facing the circumferential direction is formed. In a state where the cap body 10 is attached to the mouth portion 3 of the container main body 2, the stepped portion 32 can be brought into contact with the rotation preventing rib 3 b of the container main body 2 from the circumferential direction. When the stepped portion 32 abuts against the rotation preventing rib 3b from the circumferential direction, the cap body 10 is restricted from being excessively tightened into the mouth portion 3.

In the present embodiment, when the coating plug 9 is located at the coating position, the guide projection 21 that is in contact with or close to the inner circumferential surface of the discharge hole 8 is formed on the outer circumferential surface of the coating plug 9. In addition, a communication groove 22 through which contents can flow from the measuring chamber 6 toward the outside of the container is formed.
The guide protrusion 21 is arranged continuously to the fitting portion 24b from above the fitting portion 24b. The guide protrusion 21 is disposed on the upper end portion of the seal cylinder 24. The guide protrusion 21 is formed on the outer peripheral surface of the seal cylinder 24 over the entire periphery. The outer peripheral surface of the guide protrusion 21 is positioned slightly inside in the radial direction from the outer peripheral surface of the fitting portion 24 b and is positioned outside in the radial direction from the outer peripheral surface of the tip end portion 26. The radial positions of the outer peripheral surfaces of the guide protrusion 21 and the fitting portion 24b may be equal to each other. The contents cannot flow between the outer peripheral surface of the guide protrusion 21 and the inner peripheral surface of the discharge hole 8. The upper end edge of the guide protrusion 21 gradually extends upward as it goes inward in the radial direction, and continues to the outer peripheral surface of the lower end portion of the distal end portion 26 of the application plug 9. In addition, the upper end edge of the guide protrusion 21 may extend straight in the radial direction.

A plurality of communication grooves 22 are formed in the guide protrusion 21 at intervals in the circumferential direction. The communication groove 22 is formed on the outer peripheral surface of the guide protrusion 21 and opens at the upper edge of the guide protrusion 21. That is, the communication groove 22 is open upward. The communication groove 22 extends in the container axis O direction. With the coating plug 9 positioned at the coating position, the lower end of the communication groove 22 opens into the measuring chamber 6.
Here, a vertical groove extending in the container axis O direction is formed on the outer peripheral surface of the distal end portion 26, and the positions of the vertical groove and the communication groove 22 in the circumferential direction are different from each other. Thereby, the momentum of the content which goes to the to-be-coated part S from the measurement chamber 6 can be suppressed. Note that the circumferential positions of the longitudinal grooves and the communication grooves 22 may coincide with each other, or the longitudinal grooves may not be formed in the distal end portion 26.

  The sum total of the channel cross-sectional areas of the plurality of communication grooves 22 is smaller than the cross-sectional area of the gap between the outer peripheral surface of the distal end portion 26 of the application plug 9 and the inner peripheral surface of the discharge hole 8. The cross-sectional view shape orthogonal to the container axis O of the communication groove 22 is a rectangular shape that is long in the circumferential direction, as shown in FIG. Note that the cross-sectional view shape of the communication groove 22 may be a rectangular shape that is long in the radial direction, or may be a semicircular shape or a triangular shape that is recessed inward in the radial direction. Further, the communication groove 22 may be configured such that the width changes as it goes in the container axis O direction.

  The applicator container 1 is provided with a cap body 10 after a metering applicator formed by assembling the inner plug member 4, the measuring cylinder member 7, and the applicator plug 9 is attached to the mouth 3 of the container body 2 filled with the contents. Is screwed into the mouth 3.

  Hereinafter, the operation of the application container 1 of the present embodiment will be described.

As shown in FIG. 2, before use of the application container 1, the lower end portion of the seal cylinder 24 of the application plug 9 is fitted inside the peripheral wall of the cylinder cylinder 12, so that the measurement chamber 6 and the communication hole 5 communicate with each other. Blocked.
In order to apply the contents in the container body 2 to the application portion S, first, the cap body 10 is moved upward to be detached from the mouth portion 3 of the container body 2, and the discharge holes 8 and the distal end portions of the application plugs 9. 26 is exposed outside the container. Here, when the cap body 10 is detached, the pulling protrusion 31a of the pulling cylinder 31 and the engaged portion 26a of the tip end portion 26 of the coating plug 9 are engaged with each other in the container axis O direction. The application plug 9 is pulled up by the cap body 10 and moved to the measuring position. At this time, since the male screw portion of the mouth portion 3 and the female screw portion of the cap body 10 are double-threaded screws, the lead of the screw is larger than that of the single-threaded configuration. For this reason, the amount of displacement in the container axis O direction with respect to the amount of rotation of the cap body 10 in the circumferential direction can be increased. As a result, the coating plug 9 can be quickly moved upward, and the cap body 10 can be quickly detached from the mouth 3 of the container body 2.

  As shown in FIG. 3, when the application plug 9 is moved to the measuring position, the upper part of the seal cylinder 24 of the application plug 9 is fitted inside the discharge hole 8, and the stopper step 24c of the application plug 9 is connected to the measurement cylinder. The first engaging protrusion 24 a of the application plug 9 is in contact with the top wall (opening peripheral edge of the discharge hole 8) of the connecting cylinder part 20 of the member 7, and the second engaging protrusion 8 a of the measuring cylinder member 7. The first engagement protrusion 24a is engaged with the second engagement protrusion 8a from below the first engagement protrusion 24a. At this time, the communication between the discharge hole 8 and the measuring chamber 6 is blocked. From this state, the cap body 10 further moves upward with respect to the mouth portion 3 of the container body 2, so that the lifting protrusion 31 a of the lifting cylinder 31 of the cap body 10 is engaged with the distal end portion 26 of the coating plug 9. The cap body 10 is removed from the container main body 2 and the application plug 9 over the portion 26a.

Next, the content in the container body 2 is caused to flow into the measurement chamber 6 through the communication hole 5 by placing the application container 1 in an inverted posture with the application plug 9 positioned at the measurement position. At this time, since the communication between the discharge hole 8 and the measuring chamber 6 is blocked by the application plug 9, a predetermined amount of content is measured in the measuring chamber 6.
Next, as shown in FIG. 5, when the distal end portion 26 of the application plug 9 located at the measurement position is pressed against the application portion S, the application plug 9 moves toward the application position. In this process, a gap between the outer peripheral surface of the distal end portion 26 of the coating plug 9 and the inner peripheral surface of the discharge hole 8 is opened to the outside of the container, and the outer insertion tube 25 is pushed into the regulating portion 11b of the inner plug member 4. Further, the lower end of the seal cylinder 24 is fitted inside the peripheral wall of the cylinder cylinder 12. Further, at this time, the guide protrusion 21 is disposed in the discharge hole 8.
As a result, the application container 1 is disconnected from the measurement chamber 6 and the communication hole 5, and is connected to the discharge hole 8 and the measurement chamber 6, and the communication groove 22 of the guide protrusion 21 and the discharge hole 8 are connected. The contents can be applied to the application portion S through the gap between the inner peripheral surface and the outer peripheral surface of the distal end portion 26 of the application plug 9.

  After use (after application), the lower end portion of the lifting cylinder 31 of the cap body 10 is fitted into the distal end portion 26 of the coating plug 9, and the lifting protrusion 31 a of the lifting cylinder 31 is engaged with the distal end portion 26. With the female threaded portion of the cap body 10 screwed into the male threaded portion of the mouth portion 3 of the container body 2 with the mating portion 26a being in contact with the engaged portion 26a from above, the lifting protrusion 31a is The cap 26 is mounted on the mouth 3 of the container body 2 while the joint 26a is moved downward.

  As described above, according to the application container 1 according to the present embodiment, when the application plug 9 is located at the application position on the outer peripheral surface of the application plug 9, the inner surface of the discharge hole 8 comes into contact with or approaches. Since the guide protrusion 21 is formed and the communication groove 22 is formed in the guide protrusion 21, the content in the measuring chamber 6 passes through the communication groove 22 before being discharged from the discharge hole 8 to the application portion S. As a result, the flow path can be narrowed, the flow resistance can be increased, and a large amount of contents can be prevented from unexpectedly flowing out from the discharge hole 8 to the application portion S.

  Further, when the application plug 9 is located at the application position, the guide protrusion 21 is in contact with or close to the inner peripheral surface of the discharge hole 8 in the radial direction, so that the application plug 9 is positioned on the application plug 9 located at the application position. Even if an external force is applied to the measuring cylinder member 7 in the radial direction, the guide protrusion 21 can be brought into contact with the inner peripheral surface of the discharge hole 8 in the radial direction. Therefore, it is possible to prevent the application plug 9 from being inclined with respect to the measuring cylinder member 7 when the tip end portion 26 of the application plug 9 located at the application position is brought into contact with the application portion S. Thereby, when the tip end portion 26 of the application plug 9 located at the application position is brought into contact with the application portion S, the size of the gap between the outer peripheral surface of the application plug 9 and the inner peripheral surface of the discharge hole 8 is reduced. It is possible to reliably suppress the change, that is, the change in the cross-sectional shape of the flow path, and it is possible to reliably suppress a large amount of contents from flowing out of the discharge hole 8 to the application portion S. .

Further, since the guide protrusion 21 is arranged continuously from above the fitting portion 24b to the fitting portion 24b fitted into the discharge hole 8 when the coating plug 9 is located at the measurement position, The communication between the discharge hole 8 and the measuring chamber 6 can be reliably blocked by the application plug 9 located at the position.
In addition, since the communication groove 22 is formed in the guide protrusion 21 and opens upward, the flow of the contents from the measuring chamber 6 to the outside of the container in the state where the application plug 9 is located at the application position. The road can be secured stably.

  The technical scope of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.

  For example, by forming at least a part of the application plug 9 with a soft material or the like, it is possible to make the application feel of the application plug 9 less irritating and comfortable and comfortable.

  In the above embodiment, the communication groove 22 is formed on the guide protrusion 21 formed on the outer peripheral surface of the coating plug 9. However, the communication groove 22 may be formed on the inner peripheral surface of the discharge hole 8. You may form in both the internal peripheral surfaces of the hole 8. FIG. When the communication groove 22 is formed on the inner peripheral surface of the discharge hole 8, as shown in FIGS. 6 and 7, the lower end of the communication groove 22 is opened downward, and the application plug 9 is located at the application position. Thus, the upper end of the communication groove 22 may be positioned above the upper end of the outer peripheral surface of the guide protrusion 21. In the example shown in the drawing, the lower end of the communication groove 22 is open to the lower surface of the top wall of the connecting cylinder portion 20. The upper end of the communication groove 22 faces the upper end edge of the guide protrusion 21 in the radial direction. Even in this case, it is possible to stably secure the flow path of the contents from the measuring chamber 6 to the outside of the container in a state where the application plug 9 is located at the application position.

  Moreover, in the said embodiment, when the guide protrusion 21 was located in the application | coating position, the guide protrusion 21 showed the structure which contact | abutted or adjoined to the internal peripheral surface of the discharge hole 8 in radial direction, but the container axis O direction It may be in contact or close. In this case, for example, a configuration in which an upward stepped portion (tapered surface) is formed on the inner peripheral surface of the discharge hole 8 as the measuring tube member 7, and a measuring tube is formed at the lower end portion of the distal end portion 26 as the application plug 9. You may employ | adopt the structure in which the guide protrusion contact | abutted or adjoined to the upper surface of the upward step part of the member 7 was formed. In this configuration, as the application plug 9, a configuration in which the outer insertion tube 25 and the distal end portion 26 are formed integrally and formed separately from the seal tube 24 may be employed.

  In addition, it is possible to appropriately replace the constituent elements in the embodiment with known constituent elements without departing from the spirit of the present invention, and the above-described modified examples may be appropriately combined.
