Description

  The present invention relates to an application container suitable for applying an appropriate amount of contents such as a liquid agent.

As an application container for applying an appropriate amount of contents such as a liquid agent accommodated in the body part of the container, for example, the one described in Patent Document 1 is known. The coating container described in Patent Document 1 is a state in which an inner stopper (distribution cylinder) attached to the mouth of the container is urged toward the distal end side of the container along the axial direction on the inner side in the radial direction of the inner stopper And a projection (coating plug) whose tip is projected from the inner plug toward the tip. In addition, the inside and outside of the container are hermetically sealed by bringing the sealing surface of the outer peripheral surface of the projection biased toward the tip side into close contact with the sealed surface of the inner peripheral surface of the inner plug.
When applying the contents, tilt the container so that the tip of the protrusion faces downward, press the tip against the surface to be coated, and push the protrusion against the inner plug toward the barrel side of the container. The released contents are applied to the surface to be applied.
Utility Model Registration No. 2553493

By the way, in the application container described in Patent Document 1, for example, contents such as a liquid agent having a relatively high volatility may be accommodated in the container, or the container may be exposed to a high outside air temperature. It may be in a state of being increased with respect to the pressure outside the container. In this way, when the above-mentioned application is performed in a state where the internal pressure of the container is increased with respect to the external air pressure, when the seal is released, the content to be applied is larger than intended by the pressure difference inside and outside the container. There was a case that erupted.
Moreover, in such an application container, the contents may unintentionally accumulate in the inner plug, and the accuracy of application may be reduced.

  The present invention has been made in view of such circumstances, and can easily equalize the internal pressure of the container to the external atmospheric pressure and prevent the contents from being ejected onto the surface to be coated in a larger amount than intended. At the same time, an object of the present invention is to provide an application container that can sufficiently ensure the accuracy of application.

In order to achieve the above object, the present invention proposes the following means.
That is, the present invention includes a container in which the contents are stored, a flow cylinder attached to the mouth of the container, the inside communicating with the body of the container, and a distal end side along the axial direction in the flow cylinder. The distribution stopper is attached in a state of being urged toward the front end and is detachably attached to the mouth of the container by an application stopper having a distal end projecting from the distribution tube to the distal end side, and the distribution A cylinder and an overcap that covers the tip of the coating plug, and a portion of the coating plug that is located in the flow tube is sealed on a surface to be sealed formed in the flow tube along the axial direction. A coating container having a sealing surface abutting from a part side, wherein a first protrusion projecting toward the tip side is provided at a tip part of the coating plug, and the first part is provided in the overcap. 1 over the protrusion along the circumferential direction of the flow tube. A second protrusion is provided to be opposed from the tightening side for tightening the cup to the mouth portion, and at least one of the first protrusion and the second protrusion, facing each other in the circumferential direction, includes the flow tube. The sliding contact surface which inclines with respect to the orthogonal plane orthogonal to the axis line is formed.

According to the application container according to the present invention, since the first protrusion and the second protrusion are provided, the overcap and the container are relatively rotated and moved to the loose side where the overcap is loosened from the mouth of the container. In addition, when the first protrusion and the second protrusion are in sliding contact with each other on the sliding contact surface and the second protrusion gets over the first protrusion on the loosening side, the second protrusion causes the first protrusion to move to the body side. By pushing in toward the tube, it becomes possible to push down the coating plug toward the barrel portion with respect to the flow tube.
Therefore, before the contents are applied to the surface to be coated, the seal surface of the coating plug and the surface to be sealed of the flow tube are separated from each other along the axial direction to release the seal, and the internal pressure of the container is increased. The pressure can be released to the outside of the container.

As a result, when the contents are applied to the surface to be coated, the contents are prevented from being ejected onto the surface to be coated more than intended due to the difference between the external pressure and the internal pressure of the container.
In addition, if the contents have unintentionally accumulated in the distribution cylinder, the contents are surely flowed down into the container by releasing the seal as described above, so that the accuracy can be improved. High application.

  Further, in the coating container according to the present invention, a base portion that is spaced apart from the coating plug along the axial direction toward the body portion side and is supported by the flow tube, and connects the coating plug and the base portion. An urging portion that urges the coating plug toward the distal end side may be formed integrally with the coating plug, and in the circulation cylinder, in the circumferential direction with respect to the circulation cylinder of the coating plug Rotation restricting means for restricting the rotational movement may be provided.

According to the application container of the present invention, since the rotation restricting means restricts the rotational movement of the application plug in the circumferential direction with respect to the flow tube, when removing the overcap from the mouth of the container, the first protrusion and Since the second protrusions are in sliding contact with each other on the sliding contact surface, it is possible to prevent the coating plug from rotating with respect to the flow tube even when the circumferential force is applied from the overcap to the coating plug. The urging portion is reliably prevented from being twisted. Therefore, the urging portion is prevented from being damaged, the urging is performed stably, and the accuracy of the seal described above is ensured.
Further, when the overcap is attached to and detached from the mouth portion, the overcap and the coating plug are surely rotated relative to each other. Therefore, as described above, the first projection is connected to the trunk portion by the second projection. It can be pushed accurately toward the side.

  Further, in the coating container according to the present invention, in the flow tube, a rotation restriction that restricts the rotational movement of the coating plug to the loose side that loosens the overcap from the mouth portion along the circumferential direction with respect to the flow tube. Means may be provided, and the application plug may be rotatable to the tightening side along the circumferential direction.

  According to the application container of the present invention, the rotation restricting means for restricting the application stopper from rotating to the loose side of loosening the overcap from the mouth of the container along the circumferential direction with respect to the flow tube is provided. Therefore, when the overcap is removed from the mouth, the overcap and the application plug are surely rotated relative to each other. Therefore, as described above, the first projection is inserted into the body by the second projection. It can be pushed accurately toward the part side. On the other hand, since the application plug is rotatable to the tightening side along the circumferential direction, when the overcap is attached to the mouth, the overcap is rotated to the tightening side. Accordingly, since the coating plug is rotated and moved to the tightening side, it is possible to ensure a seal (sealing property) without pushing down the coating plug. Therefore, the application plug is prevented from remaining pushed into the body portion side by the attached overcap, and the above-described sealing is reliably performed.

  According to the application container according to the present invention, the internal pressure of the container can be easily made equal to the external air pressure, and the contents are prevented from being ejected to the surface to be applied in a larger amount than intended, and the application accuracy is sufficiently high. It can be secured.

Next, application of contents using the application container 10 configured as described above will be described.
First, as shown in FIG. 1, in the process of turning the overcap 5 around the axis O and removing it from the mouth in a state where the overcap 5 is attached to the mouth of the container 2, 3 moves upward. Then, the pressing surface 51a of the overcap 5 and the upper surface of the flange portion 31, the tapered surface 52c and the tapered surface 33, and the lower surface of the stepped portion 52b and the upper end opening edge of the flow tube 3 are separated in the axis O direction. The radially inner side of the wall 52a communicates with the outside of the container 2.

  Further, in FIG. 4, the second protrusion 52 d of the overcap 5 is the first protrusion 41 b of the application plug 4 as the overcap 5 rotates and moves to the loose side C <b> 1 with respect to the flow tube 3. The first sliding contact surface 7a facing the tightening side C2 of the second sliding contact surfaces 7a, 7b faces the loosening side C1 of the first and second sliding contact surfaces 9a, 9b of the second protrusion 52d. The second protrusion 52d gets over the first protrusion 41b while the second sliding contact surface 9b is in sliding contact. At this time, the second protrusion 52d pushes the first protrusion 41b downward, and the application plug 4 is pressed downward relative to the flow tube 3.

When the coating plug 4 is pushed down in this way, the sealing surface 44 of the coating plug 4 and the sealed surface 34 of the flow tube 3 are separated from each other in the direction of the axis O, and the seal is released.
In this state, the inside of the container 2, the inside of the distribution cylinder 3, the inside of the overcap 5, and the outside of the container 2 are communicated, and the pressure inside the container 2 (internal pressure) is higher than the pressure outside the container 2 (external pressure). If so, the pressure is released to the outside of the container 2.

  In the process of further removing the overcap 5 from the mouth of the container 2 from this state, the first protrusion 41b and the second protrusion 52d are in sliding contact as described above, while the second protrusion 52d is above the first protrusion 41b. The coating plug 4 is moved upward with respect to the flow tube 3 by the urging toward the upper side of the elastic member 42, and the sealing surface 44 and the sealed surface 34 are moved away from the first protrusion 41 b. Is sealed again.

  Next, after removing the overcap 5 from the mouth of the container 2, the container 2 is tilted so that the tip 41 of the coating plug 4 faces downward, and the tip 41 is pressed against the surface to be coated and pushed into the flow tube 3. Then, the seal is released, and the content flows out from the groove 41a of the coating plug 4 and is applied. At this time, the contents in the container 2 and the air (and outside air) in the flow cylinder 3 are satisfactorily replaced by the groove 62 b of the cylinder 62 and the hole 62 a of the cylinder 62.

Further, in the process of attaching the overcap 5 to the mouth of the container 2 after the application is finished, the overcap 5 is attached to the mouth of the container 2 in the reverse order as described above.
When the overcap 5 is attached to the mouth portion of the container 2, as shown in FIG. 1, the holding surface 51a of the overcap 5 and the upper surface of the flange portion 31, the tapered surface 52c and the tapered surface 33, and the lower surface of the stepped portion 52b are distributed. Since the upper end opening edge of the cylinder 3 is in close contact with each other, the radially inner side of the wall 52a and the outside of the container 2 are blocked.

  As described above, when the applicator plug 4 is pushed downward with respect to the flow tube 3, if the applicator plug 4 has moved down unintentionally, the top wall 41 c of the applicator plug 4 The lower surface is in contact with the upper end surface of the rod 61 in the push-in restricting member 6 to restrict the downward movement of the coating plug 4.

As described above, according to the application container 10 of the present embodiment, since the first protrusion 41b and the second protrusion 52d are provided, the overcap 5 and the container 2 are replaced by the overcap 5 and the opening of the container 2. When the first projection 41b and the second projection 52d are slidably contacted with each other on the first sliding contact surface 7a and the second sliding contact surface 9b, the second projection 52d When the first protrusion 41b is moved over the loose side C1, the first protrusion 41b is pushed downward by the second protrusion 52d, so that the application plug 4 is pushed downward with respect to the flow tube 3. It becomes possible.
Therefore, before the contents are applied to the surface to be coated, the seal surface 44 of the coating plug 4 and the surface to be sealed 34 of the flow tube 3 are separated from each other along the axis O direction to release the seal, and the container When the internal pressure of 2 is increased, the pressure can be released to the outside of the container 2.

As a result, when the contents are applied to the surface to be coated, it is possible to prevent the contents from being ejected onto the surface to be coated more than intended due to the difference between the external pressure and the internal pressure of the container 2. Application can be performed with high accuracy from the beginning of use.
In the present embodiment, since the first sliding contact surface 7a and the second sliding contact surface 9b are formed on both the first protrusion 41b and the second protrusion 52d, the second protrusion 52d overcomes the first protrusion 41b with less resistance. That is, the resistance when the overcap 5 is attached to and detached from the mouth of the container 2 is reduced.

  In addition, when the contents are unintentionally accumulated in the distribution cylinder 3, the contents are surely flowed down into the container 2 by releasing the seal as described above. Highly accurate application is possible.

Further, since the rotation restricting means 8 restricts the rotational movement of the coating plug 4 in the circumferential direction with respect to the flow tube 3, when the overcap 5 is removed from the mouth of the container 2, the first protrusion 41 b and the second protrusion 41 b Even if a circumferential force is applied from the overcap 5 to the application plug 4 by the protrusion 52d being in sliding contact with each other on the first and second sliding contact surfaces 7a, 7b, 9a, 9b, the application plug 4 is in the cylindrical portion. Therefore, it is possible to prevent the elastic member 42 from being twisted. Therefore, the elastic member 42 is prevented from being damaged and urged stably, and the accuracy of the seal described above is ensured.
In addition, when the overcap 5 is attached to and detached from the mouth portion, the overcap 5 and the coating plug 4 are reliably rotated and moved relative to each other. As described above, the first protrusion 41b is formed by the second protrusion 52d. Can be pushed down with high precision.

  When the application plug 4 is rotatable in the circumferential direction with respect to the flow tube 3, each of the first protrusion 41 b and the second protrusion 52 d when the attachment of the overcap 5 to the mouth is completed. Even when the tip portion 41 is pushed down with respect to the flow tube 3 by abutting the top portions 7c and 9c, the first protrusion 41b is urged by the urging force of the elastic member 42 that urges the coating plug 4 upward. And the second protrusion 52d can be slidably contacted with each other on the first and second sliding contact surfaces 7a, 7b, 9a, 9b, and the coating plug 4 can be rotated with respect to the flow tube 3. Therefore, it is possible to prevent the coating plug 4 from being pushed downward by the attached overcap 5 and to ensure the above-described sealing.

  In addition, since the contents 62 and the air are efficiently replaced by the grooves 62b in the cylindrical body 62 and the outer peripheral surface of the cylindrical body 62 of the push-in restricting member 6, the distal end portion 41 of the coating plug 4 is formed. When the content is applied by releasing the pressing seal against the surface to be coated, the content is more smoothly poured out from the tip portion 41.

Next, the application container 20 according to the second embodiment of the present invention will be described.

  Further, as shown in FIGS. 5 and 6, the first protrusion 41b and the second protrusion 52e are arranged with their relative positions in the circumferential direction being shifted. As a result, of the first and second sliding contact surfaces 19a and 19b of the second protrusion 52e, the second sliding contact surface 19b facing the loose side C1 becomes the first and second sliding contact surfaces 7a of the first protrusion 41b. 7b is opposed to the first sliding contact surface 7a facing the tightening side C2 from the tightening side C2.

  As shown in FIG. 7, in the overcap 5 of the application container 30 of the present embodiment, the portion located on the upper side of the stepped portion 52 b on the inner peripheral surface of the wall portion 52 a is below the lower surface 29 d of the top wall portion 52. A plurality of second protrusions 52f projecting toward the end are formed at intervals along the circumferential direction. Specifically, the second protrusions 52f are formed in a plate shape extending downward from the lower surface 29d along the axis O direction on the inner peripheral surface of the wall 52a. In addition, the radially inner end of the second protrusion 52f is spaced apart from the axis O.

  Further, as shown in FIG. 8, the top portion 29 c formed at the lower end portion of the second protrusion 52 f has a substantially rectangular surface shape facing downward, and extends along the radial direction on an orthogonal surface orthogonal to the axis O. It exists, and the edge part of the radial direction outer side is continuing to the internal peripheral surface of the wall part 52a. Moreover, the both ends of the said circumferential direction in the top part 29c are each formed in the convex curve shape connected to the both sides | surfaces which face the said circumferential direction in the 2nd protrusion 52f.

  Further, as shown in FIGS. 7 and 8, the first protrusion 41b and the second protrusion 52f are arranged with their relative positions in the circumferential direction being shifted. Thereby, the side surface of the second protrusion 52f facing the loose side C1 faces the first sliding contact surface 7a of the first protrusion 41b facing the tightening side C2 from the tightening side C2. Further, the side surface of the second protrusion 52f facing the tightening side C2 faces the second sliding contact surface 7b of the first protrusion 41b facing the loosening side C1 from the loosening side C1.

By pushing the first protrusion 41 b downward, the coating plug 4 can be pushed downward with respect to the flow tube 3. Accordingly, the same effects as those of the above-described embodiment can be obtained.

Next, a coating container 40 according to the fourth embodiment of the present invention will be described.

In addition, the same code | symbol is attached | subjected to the same member as the above-mentioned 1st thru | or 3rd embodiment, and the description is abbreviate | omitted.

  As shown in FIGS. 9 to 11, in the coating stopper 14 of the coating container 40 of the present embodiment, the portion located between the grooves 41 a adjacent to each other in the circumferential direction of the upper end surface of the tip 41 is directed upward. A plurality of first protrusions 41e are formed. Specifically, the first protrusion 41e has a slidable contact surface 37a whose projecting height gradually decreases from the loose side C1 to the tightening side C2 along the circumferential direction. It is inclined with respect to an orthogonal plane orthogonal to the axis O.

  Further, at the end on the loose side C1 of the slidable contact surface 37a, the radially inner end is connected to the peripheral edge of the upper end surface of the tip 41, and extends toward the radially outer side along the orthogonal surface. 37c is formed. Moreover, in the top part 37c, the edge part of the slack side C1 continues to the upper end opening edge of the groove 41a.

  Further, as shown in FIG. 9, the first protrusion 41e and the second protrusion 52f are arranged with their relative positions in the circumferential direction being shifted. Accordingly, the side surface of the second protrusion 52f facing the loose side C1 faces the sliding contact surface 37a of the first protrusion 41e facing the tightening side C2 from the tightening side C2. Further, the side surface of the second protrusion 52f facing the tightening side C2 faces the surface facing the loosening side C1 at the upper end portion of the groove 41a from the loosening side C1.

  Further, as shown in FIG. 12, in this embodiment, instead of the rotation restricting means 8 described in the above embodiment, a rotation restricting means 18 comprising a ratchet mechanism is arranged between the flow tube 3 and the application plug 14. Has been established. A known ratchet mechanism can be used as the rotation restricting means 18. That is, a plurality of first protrusions 18a protruding outward in the radial direction and extending along the axis O direction are formed on the outer peripheral surface of the large-diameter portion of the coating plug 14 at intervals in the circumferential direction. A plurality of second protrusions 18b projecting radially inward and extending along the axis O direction are formed on the inner peripheral surface of the flow tube 3 corresponding to the portion 18a at intervals in the circumferential direction. A ratchet mechanism is formed in which the first and second protrusions 18a and 18b are engaged with each other with a slight gap therebetween in the circumferential direction, and the rotation composed of these first and second protrusions 18a and 18b. The regulating means 18 is used. The rotation restricting means 18 restricts the rotational movement of the coating plug 14 to the loose side C1 with respect to the flow tube 3 and allows the rotational movement to the tightening side C2.

  As described above, in the application container 40 of the present embodiment, when the overcap 5 and the container 2 are rotationally moved relative to the loose side C1 where the overcap 5 is loosened from the mouth of the container 2, When the first protrusion 41e and the second protrusion 52f are in sliding contact with each other on the sliding contact surface 37a and the top portion 29c, the second protrusion 52f gets over the first protrusion 41e on the loose side C1, and the second protrusion 52f causes the first protrusion By pushing the protrusion 41e downward, the coating plug 14 can be pushed downward with respect to the flow tube 3. Accordingly, the same effects as those of the above-described embodiment can be obtained.

  Further, since the rotation restricting means 18 is provided, the rotational movement of the coating plug 14 to the loose side C1 with respect to the flow tube 3 is restricted, and when the overcap 5 is removed from the mouth, the overcap is surely secured. Since 5 and the coating plug 4 are relatively rotated, as described above, the first protrusion 41e can be accurately pushed downward by the second protrusion 52f. On the other hand, since the application plug 14 is rotatable to the tightening side C2, when the overcap 5 is attached to the mouth, the overcap 5 is rotated to the tightening side C2. Accordingly, since the application plug 14 is rotationally moved to the tightening side C2, it is possible to ensure a seal (sealing performance) without pushing down the application plug 14. Therefore, the application plug 14 is prevented from remaining pressed by the attached overcap 5 and the above-described sealing is reliably performed.

The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.
For example, in the above-described embodiment, the first protrusion is formed with a first sliding contact surface (sliding contact surface) that gradually decreases in height from the loose side C1 to the tightening side C2 along the circumferential direction. In the second protrusion, the second slidable contact surface is formed in which the projecting height gradually decreases from the tightening side C2 toward the loosened side C1. Is provided in at least one of the first protrusion and the second protrusion that are opposed to each other in the circumferential direction, and is not limited to the above-described embodiment.

That is, when the sliding contact surface is provided in the portion facing the tightening side C2 of the first projection, the sliding contact surface does not have to be provided in the portion facing the loosening side C1 of the second projection, and the loosening side C1 of the second projection. When the slidable contact surface is provided on the portion facing the, the slidable contact surface may not be provided on the portion facing the tightening side C2 of the first protrusion.
In addition, although it has been described that a plurality of first protrusions and second protrusions are formed along the circumferential direction, only one first protrusion and second protrusion may be formed.

  In addition, although the rotation restricting means 8 and 18 are disposed in the distribution cylinder 3, the present invention is not limited to this, and the rotation restricting means 8 and 18 may not be disposed. .

  In addition, a plurality of grooves 41a extending along the axis O direction are formed on the outer peripheral surface of the small-diameter portion of the coating plug 4 at intervals in the circumferential direction. As long as it is formed so that the contents can be passed from the top to the top, it is not limited to the shape of the present embodiment. That is, for example, a spiral groove may be formed on the outer peripheral surface of the tip portion 41.

  Further, although the push-in restricting member 6 is disposed, the present invention is not limited to this, and the push-in restricting member 6 may not be disposed.

  In addition, in the range which does not deviate from the main point of this invention, it is possible to replace suitably the component in above-mentioned embodiment with a well-known component, and you may combine the above-mentioned modification suitably.
