Description

  The present invention relates to a storage container for stick-shaped cosmetics for storing stick-shaped cosmetics such as lipstick, lip balm, and eyeline.

A plate member comprising a conventional plate for storing a bar-shaped cosmetic, a screw rod having a screw thread formed on the outer peripheral portion protruding downward from the center of the bottom surface of the plate, and a screw thread of the screw rod of the plate member In this case, the container for a bar-shaped cosmetic product provided with a helical body having a female screw part of approximately one rotation formed on the upper inner wall surface forms a stopper part through which the female screw part passes by being pushed into the lower end part of the screw bar.
Those formed with such a stopper part have a problem such that when the plate member is rotated so as to be positioned at the top dead center, the stopper part acts like a jackie and the stopper part is damaged. .
In order to solve this problem, the stopper portion is formed by forming a notch in the U-shaped portion near the lower end portion of the screw rod, and the stopper member is rotated so that the plate member is positioned at the top dead center. Although it is considered that the rotation is stopped by the stopper piece when it is moved, when setting the plate member to the spiral body, the stopper piece of the plate member must pass through the female screw part of the spiral body, forming a sturdy stopper piece However, if the stopper piece is weak, there is a disadvantage that the plate member is detached from the spiral body due to the screw force during rotation.

JP-A-8-126526

  In view of the above-described conventional drawbacks, the present invention can easily perform the setting operation of the spiral body and the dish member, and when the dish member is rotated so as to be positioned at the top dead center, It is an object of the present invention to provide a storage container for a bar-shaped cosmetic product that can prevent rotation of the dish member and the spiral body and can reliably prevent a problem that the dish member is detached from the spiral body.

  The above and other objects and novel features of the present invention will become more fully apparent when the following description is read in conjunction with the accompanying drawings.

  However, the drawings are for explanation only and do not limit the technical scope of the present invention.

In order to achieve the above object, the present invention provides a plate member comprising a plate for supporting a bar-shaped cosmetic product, and a screw rod having a thread formed on the outer peripheral portion thereof excluding a lower end portion protruding downward from the bottom center portion of the plate. In a container for a bar-shaped cosmetic product provided with a helical body in which a female screw portion of approximately half rotation or one rotation that engages with a screw thread of the screw rod of the plate member is formed on the upper inner wall surface, the female screw portion of the helical body faces each other. An anti-rotation piece that is formed integrally with the screw groove of the screw rod of the countersunk member and that can pass through the screw groove of the helical body, It is formed on the screw rod of the plate member so as to be integrated with the lower position, or is formed through a gap at the lower position of the rotation prevention piece, and when the plate member is positioned at the top dead center, Female thread thread groove Retaining formed protrusion is positioned in the gap, it constitutes a container for rod-like cosmetic by the retaining preventing means can be inserted into the screw groove.

As is clear from the above description, the present invention has the following effects.
(1) According to claim 1, the screw of the screw rod of the countersink member is rotated by positioning the rotation prevention piece at the lower position of the screw rod of the countersunk member in the screw groove of the female threaded portion of the spiral body, and pushing and rotating the counterplate and the spiral member. The mountain and the female threaded portion of the spiral body are screwed together, and the plate member can be moved up and down relative to the spiral body.

Therefore, it is possible to easily perform the setting operation of the dish member to the spiral body.
(2) When the plate member is positioned at the top dead center according to the above (1), the rotation preventing piece formed on the screw rod of the plate member collides with the end of the female screw portion of the helical body, and further rotates. Is impossible.

For this reason, even if an unnecessary force is applied, it is possible to efficiently prevent damage without applying a screw force as in the prior art.
(3) When the dish member is positioned at the top dead center according to (1), it is possible to reliably prevent the dish member from coming out of the spiral body by the retaining prevention means.
(4) According to the above (1), it is only necessary to provide the anti-rotation piece and the retaining means, so that the structure is simple and can be implemented easily.
(5) According to the second aspect, the same effects as in the above (1) to (4) can be obtained, and the rotation prevention piece and the retaining means can be integrally formed in an inverted L shape, which can be easily manufactured.

  Thereafter, as shown in FIG. 10, when the plate member 6 and the spiral body 5 are rotated so that the plate member 6 is lowered, the threads 11, 11 of the screw rod 12 of the plate member 6 become the female thread portion of the spiral body 5. 21 and 21 are screwed together. For this reason, the plate member 6 can be moved up and down by rotating the plate member 6 and the spiral body 5 forward and backward.

  When the countersunk member 6 is positioned at the top dead center, the anti-rotation pieces 13 and 13 of the screw rod 12 of the countersunk member 6 are end portions 21a and 21a of the female threaded parts 21 and 21 of the spiral body 5 as shown in FIGS. And the upper surfaces of the projecting pieces 22 and 22 of the retaining means 23 and 23 are the lower end portions of the female thread portions 21 and 21 of the spiral body 5 near the end portions 21a and 21a. It abuts and prevents the dish member 6 from coming off the spiral body 5.

  After setting the plate member 6 and the spiral body 5, the O-ring 16 is set in the O-ring insertion ring groove 17 of the spiral body 5, and the cylindrical member insertion recess 15 of the spiral body 5 is inserted into the lower end portion of the cylindrical member 7. The crimping part 18 is formed in the recessed part 19 site | part, and the cylinder member 7 is attached rotatably.

  At this time, the engaging pieces 10, 10, 10, 10 of the dish 9 of the dish member 6 are engaged with the engaging recesses 26, 26, 26, 26 of the cylinder member 7, and the dish member 6 is moved up and down in the cylinder member 7. It is attached so that it can move and rotate integrally.

  Thereafter, the spiral body 5 is covered with the hook member 4 and the cap 8 is attached to the cap fitting portion 3 of the hook member 4 to complete the assembly.
