JP 2012-232776 A

In the conventional applicator container, it is desired to reuse the applicator by replacing it with a new tube container after the contents in the tube container have been used.

The present invention has been made in view of the circumstances described above, and an object of the present invention is to provide a reusable applicator container.

<1> An application container according to an aspect of the present invention includes a tube container containing a content, a joint part fixed to the tube container, and an applicator detachably attached to the joint part. The applicator includes an inner plug member attached to the joint part and having a communication hole communicating with the inside of the tube container; an application member having a hole formed therein, the application member rotating with respect to the inner plug member to open and close the pouring hole, the joint part having an elastic piece capable of elastic displacement; An operation button and a first locking portion provided on an elastic piece are provided, and the inner plug member is provided with a window through which the operation button is exposed to the outside of the inner plug member, and the first locking portion. and a second locking portion that restricts detachment of the inner plug member from the joint part by being locked, and the first locking portion and the second locking portion are provided when the elastic piece is elastically displaced. The lock with the part is released.

According to the present invention, the user removes the applicator from the joint part when the tube container runs out of contents. The user attaches the removed applicator to the joint part of the new tube container. This reuses the applicator. When removing the applicator, the user elastically displaces the elastic piece of the joint part. Since the operation button is exposed through the window hole of the inner plug member, the user can easily operate the elastic piece via the operation button. When the elastic piece is elastically displaced, the locking between the first locking portion and the second locking portion is released. As a result, the restriction on the detachment of the inner plug member from the joint part is released. As described above, the applicator can be easily removed from the joint part.

<2> In the application container according to <1> above, the inner plug member has a topped cylindrical shape having a first top wall portion, and the application member includes a plurality of application balls and a plurality of the application balls. a support member having a second top wall portion formed with a plurality of support recesses that are rotatably supported separately; and a female screw cylinder screwed to the inner plug member; a topped cylindrical covering member having a third top wall portion formed with a plurality of through-holes for separately projecting upward the upper portion of the ball, wherein the second top wall portion The third top wall portion is formed in an annular shape surrounding the central axis of the tube container, and the pouring hole is formed through the third top wall portion in the vertical direction and is open toward the inside of the second top wall portion. A configuration may be employed in which a plug extending upward and detachably fitted to the pouring hole is formed on the top wall.

In this case, since the plug of the first top wall closes the spout hole of the third top wall, in the standby state before the support member and the covering member are raised with respect to the inner plug member, It is possible to prevent communication between the inside of the tube container and the pouring hole, and it is possible to reliably suppress the leakage of the contents inside the tube container. Furthermore, it is possible to prevent the contents from coming into contact with the outside air that has passed through the pouring hole.
When applying the contents, the user unscrews the support member from the inner plug member and raises the support member and the covering member relative to the inner plug member, and the plug opens the spout hole. Here, since the application container is provided with a plurality of application balls, the plurality of application balls can be pressed almost simultaneously against the portion to be applied, and the contents poured out from the spout hole can be applied. As a result, during application, for example, the applied part such as the skin can be embedded between adjacent application balls, or the pressing force against the applied part can be relaxed, etc., resulting in a massage effect. can be improved.
The second top wall is formed in an annular shape surrounding the central axis of the tube container when viewed from above and below, and the pouring hole is open toward the inside of the second top wall. To smoothly pour out the content from the pouring hole even when the coating ball is pressed against the part to be coated without blocking the pouring hole when the coating ball supported in the supporting concave portion of the coating ball is applied. can be done.

<3> In the applicator container according to <2> above, the third top wall portion is formed with an upper connecting cylinder that extends downward and surrounds the pouring hole from the outside in the radial direction, and the first top wall A lower connecting tube that extends upward and surrounds the communication hole from the outside in the radial direction and is slidably fitted to the upper connecting tube is formed in the portion, and the inner plug member and the support member are formed. wherein the supporting member and the covering member contact each other when they move upward with respect to the inner plug member, so that the supporting member and the covering member move further toward the inner plug member, A first regulating projection and a second regulating projection are formed separately for regulating upward movement. A configuration may be adopted in which the stopper is removed from the pouring hole while the lower connecting cylinder is fitted.

In this case, since the first restricting protrusion and the second restricting protrusion are separately formed on the inner plug member and the support member, the support member and the covering member move upward further with respect to the inner plug member. In this state, the pouring hole can be opened by removing the stopper from the pouring hole while keeping the lower connecting tube fitted to the upper connecting tube. As a result, the contents in the tube container can be poured out from the pouring hole through the communicating hole, the inside of the lower connecting cylinder, and the inside of the upper connecting cylinder without leaking from between the lower connecting cylinder and the upper connecting cylinder. can.

<4> In the applicator container according to <2> or <3> above, the shape of the second top wall when viewed from the top and bottom has a major axis and a minor axis that intersect each other on the central axis. A configuration may be employed in which the plurality of support recesses are formed in a flat shape, and are provided at respective positions on both sides of the central axis in the long axis direction in which the long axis extends in the second top wall.

In this case, since the plurality of support recesses are provided in the second top wall portion at respective positions sandwiching the central axis in the longitudinal direction, the pouring holes correspond to the plurality of application balls when viewed from the top and bottom. Since they are sandwiched in the long axis direction, the contents can be evenly applied to the part to be applied with little bias.
A plurality of support recesses are provided at intervals in the longitudinal direction on the second top wall portion, which has a flat shape in plan view when viewed from above and below, so that a large diameter of each application ball is ensured. Therefore, the massage effect can be effectively improved.

<5> In the applicator container according to any one of <1> to <4> above, the plan view shape of the joint part when viewed from the top and bottom direction has a long axis and a short axis that intersect each other on the central axis. A plurality of said elastic pieces are provided in said joint part at respective positions sandwiching said central axis in the longitudinal direction in which said longitudinal axis extends, and said plurality of window holes are provided in said inner plug member In the above, a configuration may be adopted in which they are provided at respective positions sandwiching the central axis in the longitudinal direction.

In this case, a plurality of elastic pieces are provided at respective positions on both sides of the central axis in the longitudinal direction of the joint part. In addition, a plurality of window holes are provided at respective positions on both sides of the central axis in the longitudinal direction of the inner plug member. Therefore, when the user elastically displaces the elastic piece, the joint part can be pinched in the longitudinal direction by, for example, the user's thumb and forefinger. This improves operability.

<6> In the applicator container according to any one of <1> to <5> above, the operation button may project from the window hole to the outside of the inner plug member.

In this case, the operation button protrudes from the inner plug member through the window hole. Therefore, the user can elastically displace the elastic piece by pressing the operation button. This improves operability.

According to this invention, the applicator can be reused.
