Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a rod-shaped cosmetic container in which the fitting structure of the cap is provided with an airtight function.

Problems to be solved by conventional techniques and ideas Various containers incorporating an airtight structure have been developed from the perspective of preventing volatile cosmetics from drying and solidifying, but conventional containers of this type do not have the function of preventing airtightness. Although there are no particular problems with respect to the surface, there are drawbacks that result in increased costs due to the complexity of the structure.

The purpose of this proposal is to eliminate the drawbacks of the conventional container by incorporating an airtight function into the fitting structure of the cap, reduce the number of container parts, and provide a bar-shaped cosmetic container that can be easily assembled and manufactured at low cost. It is.

Means for Solving the Problems The present invention is characterized in that the fitting and locking structure of the cap also has an airtight function, and includes a rotatable hakama tube 1 having a spiral groove 2 on the inner circumferential surface; A body tube 3 that is inserted into the hakama tube 1 and has an annular collar 4 protruding from the outer circumferential surface that is engaged with an annular step 5 provided on the upper inner circumferential surface of the hakama tube 1; and the hakama tube 1,
A middle fitting cylinder 6 which is fitted and fixed to the side of the hakama cylinder 1 and whose lower end abuts against the upper surface of the annular collar 4 to prevent the body cylinder 3 from being pulled out; A cosmetic dish 7 which is housed in a vertically movable manner and has an annular rib 8 protruding from its outer peripheral surface that comes into close sliding contact with the inner wall surface of the body barrel 3;
A pin 10 protruding from both sides of the lower part passes through a vertical hole 11 bored on both sides of the lower half of the body barrel 3 and passes through the spiral groove 2.
and a leg tube 9 that is engaged with the inner tube 6.
A cap body 1 made of resin and having the same shape as the cap 12 is installed inside a cylindrical cap 12 that is removably fitted into the cap 12.
3 is fixed, an appropriate gap 14 is interposed between the circumference of the cap body 13 and the cap 12, and a fitting wall 16 having an appropriate elasticity by forming an inner diameter widened part 15 in the lower part of the cap body 13, and the lower part thereof. A contact piece 17 is provided which is bent outward and whose tip contacts the inner circumferential surface of the cap 12, and an annular recess 18 that is perforated in the inner circumferential surface of the fitting wall 16 is provided to protrude from the outer circumferential surface of the inner sleeve 6. The gist of the present invention is to provide a structure in which the annular convex portions 19 are tightly fitted together.

Embodiment The details of the present invention will be explained below with reference to an embodiment shown in the drawings. 1 is a rotatable hakama tube having a spiral groove 2 on the inner circumferential surface; 3 is a rotatable hakama tube that is inserted into the hakama tube 1 and protrudes from the outer circumferential surface. A body tube 6 is interposed between the body tube 3 and the hakama tube 1, and the annular collar 4 is engaged with an annular step 5 provided on the upper inner peripheral surface of the hakama tube 1, that is, the upper part of the spiral groove 2. The middle tool tube 7 is fixed to the hakama tube 1 side, and its lower end abuts against the upper surface of the annular collar 4 to prevent the body tube 3 from being pulled out. A vertically movable cosmetic dish that comes into close sliding contact with the inner circumferential surface of the cylinder 3, and a leg cylinder 9 that is integrally suspended from the lower part.
The pins 10 protruding from both sides of the lower part pass through the vertical holes 11 bored on both sides of the lower half of the body barrel 3 and engage with the spiral groove 2, and by rotating the hakama tube 1, a cosmetic dish is formed. 7 will now move up and down inside the body cylinder 3. 12 is a cylindrical cap that is removably fitted into the inner tube 6;
Reference numeral 3 denotes a cap body made of resin with a top wall 13' fixed to the inside of the cap 12 with adhesive or the like, with an appropriate gap 14 interposed between the circumferential body and the cap 12, and an inner diameter at the bottom. A fitting wall 16 that forms a widened portion 15 and has appropriate elasticity, and a contact piece 17 that is bent outward and whose tip contacts the inner circumferential surface of the cap 12 is provided at the bottom of the fitting wall 16, and the inner circumference of this fitting wall 16 is bent outward. An annular convex portion 19 protruding from the outer peripheral surface of the inner fitting cylinder 6 is tightly fitted into an annular concave portion 18 bored in the surface.

Functions and Effects of the Invention Accordingly, in the present invention, by rotating the hakama tube 1, the cosmetic dish 7 can be moved up and down, allowing smooth delivery and storage of cosmetics, and the annular rib 8 of the cosmetic dish 7. is in close sliding contact with the inner circumferential surface of the body tube 3 to block air from entering the body tube 3 from the lower part of the container, and the annular collar 4 of the body tube 3 is locked to the annular stepped portion 5 of the hakama tube 1. , Hakama tube 1
The lower end surface of the inner sleeve 6 fixed to the side is in abutting contact with the upper surface of the annular collar 4, completely preventing the body sleeve 3 from being pulled out and allowing it to be stably assembled into the hakama sleeve 1. Therefore, smooth rotation of the hakama tube 1 can be obtained without any possibility of interfering with the rotating action of the hakama tube 1.

Furthermore, when the cap 12 is attached, the fitting wall 16 of the cap body 13 fits into the inner tube 6, and the annular convex portion 19 of the inner tube 6 tightly fits into the annular recess 18 of the fitting wall 16.
A stable fitted state is obtained by preventing the cap 12 from falling off, and the close engagement of the annular concavo-convex portions 18 and 19 blocks outside air from entering the inside of the cap 12, resulting in a sufficient airtight effect. Furthermore, an appropriate gap 14 is interposed between the circumferential body portion of the cap body 13 and the cap 12, and a contact piece 17 provided at the lower part of the fitting wall 16 is bent outward and its tip is connected to the cap 1.
2, and the fitting wall 1 comes into contact with the inner peripheral surface of the fitting wall 1.
The elasticity of the cap 6 is fully utilized, the cap 12 can be easily attached and detached, and the annular uneven portions 18 and 19 can be in a good tight fitting state, which has the advantage of further promoting the airtight effect. .
