Description

[Detailed description of the invention] The present invention aims to avoid overlapping of parts as much as possible by integrally forming a guide tube with a vertical hole for raising and lowering the cosmetic container in the lower part of the container, and to avoid overlapping of the parts as much as possible. By making the diameter smaller than that of the container and by concentrating the functional part for raising and lowering the cosmetic container in the lower half of the container, a slender and good-looking bar-shaped cosmetic container is obtained. A guide cylinder 4 formed integrally with the lower part of the container cylinder 3 and having a smaller diameter than that of the container cylinder 3 is inserted into a rotating cylinder 1 made of synthetic resin and having a spiral groove 2 carved on its circumferential surface. In addition, a long leg tube 7 with a reduced diameter compared to the cosmetic container 6 is integrally formed at the bottom of the cosmetic container 6 stored in the container 3.
is inserted into the guide tube 4, and a pin 8 protruding from the lower part of the leg tube 7 is engaged with the vertical hole 5 formed on both sides of the guide tube 4 and the spiral groove 2 of the rotary tube 1, and the An annular diameter-reducing recess 11 having an appropriate width is formed on the outer circumferential surface of the rotary cylinder 1, and longitudinal locking protrusions 12, which are shorter and smaller than the width of the diameter-reducing recess 11, are provided at arbitrary locations on the diameter-reducing recess 11. A metal inner tube 9 is forcibly fitted between the rotary tube 1 and a metal outer tube 10 fitted on the outside of the rotary tube 1, and the inner peripheral surface of the inner circumferential tube 9 is The annular convex portion 13 formed in the diameter-reducing recess 11 is engaged with the upper step 11', and the locking protrusion 12 is engaged with the vertical groove 14 provided in the inner tube 9. The main structure is as follows.

The specific structure of the present invention will be described below with reference to an embodiment shown in the drawings. Reference numeral 1 denotes a synthetic resin-type rotary cylinder having a spiral groove 2 carved on its inner circumferential surface; 3 a container cylinder; A guide tube 4 with vertical holes 5 bored on both sides is connected to the lower part of the container, and the guide tube 4 has a reduced diameter compared to the container tube 3.

Reference numeral 6 designates a cosmetics container, which is integrally formed with a long leg tube 7 having a pin 8 at the bottom, and this leg tube 7 is also reduced in diameter compared to the cosmetics container 6. Insert the guide tube 4 and the leg tube 7 of the cosmetic container 6 in the container 3 into the guide tube 4, respectively.
The pins 8 of the leg tube 7 are engaged with the vertical hole 5 and the spiral groove 2, respectively, and the makeup platform 6 is raised and lowered by rotation of the rotary tube 1.

Reference numeral 9 denotes a metal inner tube fitted on the outside of the rotary tube 1, and 10 denotes a metal outer tube tightly fitted to the inner tube 9 and the rotary tube 1.

A diameter-reducing recess 11 is formed on the outer peripheral surface of the rotary cylinder 1, and a vertical locking protrusion 12 is provided protruding from the diameter-reducing recess 11, and an annular projection is formed on the inner peripheral surface of the inner member cylinder 9. 13 is engaged with the upper step portion 11' of the diameter-reducing recess 11, and the engagement protrusion 12 is engaged with the vertical groove 14 cut out in the inner tube 9.

In order to prevent the guide tube 4 from coming off, an annular protrusion 16 protruding from the upper outer periphery of the guide tube 4 is engaged with an annular groove 15 formed on the upper inner peripheral surface of the rotary tube 1. 1 has an inner circumferential collar 17 that supports the guide tube 4 inside in place of the conventional bottom cover.
An outer peripheral collar 18 for supporting the outer cylinder 10 is integrally formed on the outside.

The present invention has a rotary cylinder 1 made of synthetic resin with a spiral groove 2 carved on the inner circumferential surface as shown in the upper part, and is smaller than the container cylinder 3 which is formed integrally with the lower part of the cylinder 3. A guide tube 4 with a smaller diameter is inserted into the guide tube 4, and a long leg tube 7 with a reduced diameter is inserted into the guide tube 4. The pins 8 protruding from the lower part of the leg cylinder 7 are engaged with the vertical holes 5 formed on both sides of the guide cylinder 4 and the spiral groove 2 of the rotary cylinder 1. An annular diameter-reducing recess 11 having an appropriate width is formed on the outer circumferential surface, and a longitudinal locking protrusion 12 that is shorter and smaller than the width of the diameter-reducing recess 11 is provided at any location of the diameter-reducing recess 11.
A metal outer cylinder 10 that protrudes and fits on the outside of the rotating cylinder 1.
A metal inner tube 9 is forcibly fitted between the rotary tube 1 and the rotary tube 1,
The annular convex portion 13 formed on the inner circumferential surface of the inner tube 9 is engaged with the upper step 11' of the diameter-reducing recess 11, and the annular convex portion 13 formed on the inner circumferential surface of the inner tube 9 is engaged with the vertical groove 14 provided in the inner tube 9. This configuration allows the locking protrusion 12 to engage with the locking protrusion 12, and has the following effects.

(1) Place the container 3 at the top, and place the vertical 7L at the bottom of this container 3.
By integrally forming the guide tube 4 having a diameter of 5, and by carving the spiral groove 2 on the inner circumferential surface of the rotary tube 1, the number of parts can be reduced by several parts compared to conventional containers of this type. In addition, polymerization of the parts (cylindrical bodies) can be avoided as much as possible, and the diameter of the guide cylinder 4 is reduced compared to the container cylinder 3, and the makeup height 6 is
A long leg tube 7 with a reduced diameter compared to the makeup platform 6 is integrally formed at the bottom of the container, and the functional part that controls the elevation of the makeup platform 6 is concentrated in the lower half of the container, resulting in a slim body. A container with a good appearance can be obtained, and furthermore, it is easy to assemble, and together with a reduction in the number of parts, this is very beneficial in reducing product costs.

(2) If the rotary tube 1 is made of resin and the inner tube 9 and the outer tube 10 are made of metal, the resin rotary tube 1 is thermal contraction occurs, and a gap is created between the forcibly fitted outer cylinder 10 and inner cylinder 9 and the rotary cylinder 1. As a result, the outer cylinder 10 and the inner cylinder 9 idle, and the rotation cylinder 1 However, in this case, the locking protrusion 12 protruding from the diameter-reducing recess 11 of the rotary tube 1 is engaged with the groove 14 of the inner tube 9, so that the rotary tube 1 is temporarily prevented from being heated. Even in the case of contraction, the rotating tube 1 can be rotated reliably, and the annular convex portion 13 of the inner tube 9 is engaged with the upper step 11' of the diameter-reducing recess 11, thereby preventing the inner tube 9 from being pulled out. The constantly rotating cylinder 1, the inner cylinder 9 and the outer cylinder 10
This allows the makeup platform 6 to be raised and lowered comfortably.
