Description

  The present invention relates to a kind of lipstick case inner tube rotation control structure. In particular, several elastic engaging and fixing pieces that protrude appropriately on the annular peripheral surface of the inner tube bottom of a kind of lipstick are installed. The tube forms an overhang installation, has an appropriate gap between it and the lipstick filling stand, can match the rotational force of the lipstick and ensure a smooth lifting operation, and it is not necessary to use any lubricant, so lipstick The present invention relates to a rotation control structure for the inner tube of a lipstick case that is safe and hygienic to use.

The structural design in which the inner tube and the lipstick body of a known lipstick case are combined with each other and controlled in rotation is formed by inserting a filling table 22 of the lipstick body 21 into the inner tube 20 as shown in FIGS. The L-shaped slide tanks 23 are respectively installed on both side pipe surfaces of the inner pipe 20. A rotary base is connected to the bottom of the tube body, and a rotation control operation for raising and lowering the lipstick body 21 is performed.
The entire raising / lowering operation is performed by forming a fitting tube 24 mainly on the outer side of the inner tube 20 and providing a spiral introduction tank 25 on the inside thereof, so that the convex shafts 26 on both sides of the filling table 22 are moved to the slide tank 23. After the insertion and combination, the fitting tube 24 is fitted into the spiral introduction tank 25, and the lipstick body 22 is moved up and down along the introduction tank 25 and the slide tank 23 on the inner tube 20 surface.
The raising / lowering operation of the known lipstick main body 21 is usually performed by grasping the outside of the fitting tube 24 with a hand, holding the bottom filling table 22 with the opposite hand, operating the filling table 22, and moving up and down according to the spiral introduction tank 25. Therefore, the lipstick body 21 can be expanded and contracted up and down by operating corresponding to the upright slide tank 23 of the inner tube 20.
However, in the known mutual combination design between the fitting tube 24 and the inner tube 20, all parts are made of a plastic material. Therefore, due to lack of roundness or poor size control during rotation, Causes mutual friction. Furthermore, the actual lipstick filling table 22 is deformed after assembly, such as deformation or looseness of the parts, or the entire part enters the structure or the size does not fit. And so on. In order to improve the situation where the rotation is not smooth, a lubricant is usually applied to the tank hole to reduce friction, but the lubricant can be mixed with the lipstick with a very high probability. However, since the lipstick is manufactured with a chemical pigment, the color of the lipstick may change when mixed with a lubricant which is a chemical material. Furthermore, the safety and hygienic conditions of the lipstick in use may be adversely affected. In addition, when the lipstick main body 21 is extended and used by applying a lubricant, it is often inconvenient because it automatically contracts to the inside due to the pressure applied to the lips.

The known structure has the following drawbacks.
That is, in the known structure, there is a situation where the rotation becomes non-smooth, loose, and sliding due to insufficient hardness of the pipe surface, insufficient roundness due to plastic deformation during molding, and bias due to indentation that may occur during assembly. To do.
The present invention provides a rotation control structure for the inner tube of a lipstick case that solves the problems of the above structure.

In order to solve the above-mentioned problems, the present invention provides the following rotation control structure of the lipstick case inner tube.
It is mainly equipped with several elastic engaging and fixing pieces that protrude appropriately on the annular peripheral surface of the lipstick inner tube bottom, and after being fitted with the fitting tube bottom, it exhibits an appropriate engagement state. Maintains a constant coefficient of friction when rotating the tube, can improve the rotation bias due to insufficient roundness of the tube,
Since it is not necessary to use any lubricant, the use of the lipstick body is safe and hygienic, and the rotation control structure of the lipstick case inner tube is characterized in that the quality of the product can be improved effectively.

  As described above, the present invention arranges the elastic engagement fixing pieces directly on the tube surface between the inner tube and the turntable, punctures in the fitting tube, and then naturally aligns and combines them in the lipstick case. A stable assembly between the tube and the spiral fitting tube can be realized, and various defects caused by the deformation of the lipstick case tube surface can be improved. Furthermore, since the application of the lubricant can be omitted, the safety in using the lipstick and the comfort of the rotating operation can be greatly improved.

As shown in FIGS. 1, 2, and 3, the present invention mainly constitutes a rotatable structure by connecting a turntable 11 to the bottom of the inner tube 10 and coupling them together. L-shaped slide tanks 12 are formed on both sides of the tube surface of the inner tube 10, and a plurality of flaky elastic members are arranged on the peripheral edge of the tube bottom connected to the turntable 11. The mating piece 13 is installed in equal parts to form a protrusion with an appropriate height. In this way, after insertion and assembly, a structure that is appropriately curved and tightly fixed is formed.
Further, a lipstick filling table 14 that slides up and down along the slide tanks 12 on both sides is inserted and installed inside the tube body. By projecting the convex shaft 15 on both sides of the filling table 14 and installing it in the slide tank 12, the slide tank 12 moves up and down in the fixed direction. Further, since the outer side of the inner tube 10 is covered by the fitting tube 16, when the fitting tube 16 is fitted by the engagement fixing piece 13 installed on the annular peripheral surface of the bottom of the inner tube 10, the elastic support assembly is made. Form. Thus, both pipe surfaces are combined while maintaining an appropriate gap.
A spiral introduction tank 17 is installed on the inner edge surface of the fitting tube 16, and the convex shafts 15 on both sides of the filling table 14 protrude into the introduction tank 17 of the fitting tube 16. By the rotation control of the turntable 11, the filling stand 14 is driven by the spiral introduction tank 17 of the fitting pipe 16, and performs the up and down operation in the fixed direction corresponding to the slide tank 12 of the inner pipe 10.
Due to the tight orientation of the engagement fixing piece 13, when the inner pipe 10 is rotated, the two pipes drilled to each other maintain a constant elastic friction inhibiting force, so that interference due to assembly deformation is caused. I will not receive it. Thus, the expansion and contraction use of the lipstick body 18 filling the inside becomes smooth. In particular, the appropriate support by the elasticity of the engagement fixing piece 13 prevents the occurrence of a situation in which the inner tube 10 is rotated by pressure even when the lipstick body 18 is extended and used, and the lipstick body 18 contracts to the inside. can do. That is, it is possible to ensure safety, stability and practicality when using lipstick.

The present invention provides a fixed gap in the insertion assembly between the inner tube 10 and the fitting tube 16 through the projecting engagement design of the engagement fixing piece 13 that is equally arranged on the annular peripheral surface of the bottom of the inner tube 10. Hold. In addition, the two tube surfaces are not in direct contact with each other, and only the engagement fixing piece 13 on the bottom annular peripheral surface is fixed and brought into close contact with each other, so that the two tube surfaces are appropriately separated. In this way, when the entire inner tube 10 is rotated, the operation can be performed stably and smoothly and without unnecessary force.
Further, since the frictional force of the entire pipe edge is constant and does not contact each other, a point contact slide movement is formed between the slide shaft 17 and the slide tank 17 that slide on both sides of the filling table 14. Therefore, it is not necessary to apply a lubricant at all, and in the packaging use of the lipstick body 18, it is possible to completely eliminate the possibility of contact with foreign substances. Thus, safety and hygiene can be ensured. Further, it is possible to improve the disadvantage that the mutual friction due to deformation at the time of assembly due to plasticity or insufficient hardness of the tube surface becomes non-smooth.
That is, the structural design between the inner tube 10 and the fitting tube 16 of the present invention can greatly reduce the number of lipstick components, and can improve the disadvantage that the rotation operation does not go smoothly in a known lipstick case. .
