Description

[Detailed Description of the Invention] The present invention relates to a dispensing structure of a dispensing cosmetic stick container.

Most conventional dispenser cosmetic stick containers require a length that is at least twice as long as the length of the cosmetic stick contained therein, making it difficult to make the container compact. Therefore, as seen in Japanese Utility Model Publication No. 52-16932, when the base cylinder is rotated while holding the sliding cylinder, the middle plate rises while the sliding cylinder descends, and when the base cylinder is reversed, the middle plate A decorative stick container has been proposed in which the sliding tube is raised while the sliding tube is lowered. However, since a keyway is bored in the inner wall of the sliding tube to stop the rotation of the inner plate, the thickness of the sliding tube becomes thicker, resulting in an ungainly container. In addition, the present applicant has filed Utility Application No. 14122 (1983)
Publication No. 139212) and Utility Application No. 58-33252 (Publication No. 139212)
59-119209) has proposed a dispensing cosmetic stick container that utilizes a screw tube with spirally intersecting spiral grooves; Since the threaded piece has the same slope as the spiral groove and is long, the width of the guide groove in the stem wall of the inner plate, which is cut out to prevent rotation, is also wide, and is used to raise and lower the cosmetics contained in the inner plate. It lacked strength.

The present invention has been improved in the above points, and will be explained in detail below with reference to the drawings.

The inner plate 2 that accommodates and holds the decorative stick 1 has a leg tube 3 hanging thereon, and a rotation stopper piece 4 and a cylindrical threaded piece 5 are protruded from the outer wall at the lower end and the inner wall at the lower end, respectively.

Further, the opposing leg tube wall of the threaded piece 5 protruding from the leg tube 3 is cut out in the vertical direction as a guide groove 6. The sliding tube 7 is a cylindrical body, and a cylindrical screwing piece 5' is provided protruding from the lower end of the inner wall. A guide groove 6' is cut out in the wall of the sliding tube 7 that the screwing piece 5' faces. Further, the inner plate 2 is slidably inserted into the sliding tube 7, and a guide groove 6' cut out in the sliding tube 7 allows the rotation prevention piece 4 of the inner plate 2 to slide. It can be freely penetrated and engaged, and the threaded engagement piece 5' protruding from the inner wall of the lower end of the sliding tube 7 slides into the guide groove 6 cut out in the leg tube 3 of the inner plate 2. It is movably penetrated and engaged. Further, the screw rod 8 has a right-up spiral groove 8a and a left-up spiral groove 8b carved into the outer wall, and the right-up spiral groove 8a has a groove width 8a' that is wider than the left-up spiral groove 8b'. The groove is wide, and the groove depth 8b'' is shallower than the groove depth 8a''. Further, the lower end of the threaded rod 8 is in contact with the tail plug 9, and the right-up spiral groove 8a is connected to the threaded engagement piece 5' protruding from the sliding tube 7, and the left-up spiral groove 8b.
are respectively screwed into screwing pieces 5 protruding from the inner wall at the lower end of the leg tube 3. The outer cylinder 10 has a rotation prevention groove 11 cut in the vertical direction to slidably engage the rotation prevention piece 4 protruding from the lower end of the leg cylinder 3 of the inner plate 2, and furthermore, the outer cylinder 1
A protrusion 12 is provided on the inner wall of the lower end of the tail plug 9 and engages with a rotation groove 13 provided around the upper circumferential wall of the tail plug 9.

The present invention has the above-mentioned structure, and when the present invention is used, when the tail plug 9 is rotated in the forward direction, the outer cylinder 10 can be freely rotated by the rotation groove 13 provided around the upper part of the tail plug 9. Because it is irremovably engaged, the outer cylinder 1
0 remains stopped, and the threaded rod 8 that abuts the tail plug 9 is interlocked and rotates forward. Furthermore, a right upward spiral groove 8a and a left upward spiral groove 8b are carved on the outer wall of the screw rod 8.
are threaded pieces 5' protruding from the inner wall of the lower end of the sliding tube 7, respectively.
are screwed together, and a screwing piece 5 protruding from the inner wall of the lower end of the leg tube 3 of the inner plate 2 is screwed together, and a rotation stopper piece 4 protruding from the lower end of the outer wall of the leg tube 3 is screwed together. Since the inner plate 2 is engaged by the anti-rotation groove 11 formed in the outer cylinder 10, the inner plate 2 starts to be raised. At the same time, since the threaded piece 5' protruding from the inner wall of the lower end of the sliding tube 7 passes through the guide groove 6 of the leg tube 3, it begins to move down. Furthermore, the above-mentioned screw engagement piece 5,
5' starts rotating forward after a temporary stop, the right-up spiral groove 8a is wider than the left-up spiral groove 8b.
a' is wider than 8b', and the depth of the groove is 8a''
Since b'' is shallow, it is impossible to screw into spiral grooves opposite to each other, and the screw can be screwed smoothly. When the sliding cylinder 7 is rotated further in the forward direction, the lower end of the sliding tube 7 comes into contact with the screw rod 8. It contacts the base cylinder 9 and cannot rotate forward.

The present invention has the above-mentioned effects, and it is necessary to widen the guide groove width of the leg tube of the inner plate as seen in Utility Application No. 58-14122 and Utility Application No. 58-33252 filed by the present applicant. The structure is such that the strength to support the cosmetics is increased, and the cylindrical threaded piece, which has been commonly used in the past, is used to sufficiently satisfy the raising and lowering mechanism. .
