Description

[Detailed description of the invention] The present invention relates to a cosmetic container, and in particular to its feeding mechanism, which simplifies the component parts and facilitates assembly, and also prevents the core chuck holding the cosmetic from separating from the container. The aim is to provide containers that are easy to use by reliably preventing this.

For this reason, the present invention is equipped with a feeding mechanism that facilitates accurate lifting, stopping, and assembly of the core chuck that holds the solid cosmetic.
The gist of the present invention will be explained below based on the embodiments shown in the drawings.

FIG. 1 is a longitudinal sectional front view showing one embodiment of the container of the present invention, in which 1 is a general term for the container, and inside the outer cylinder 8 forming the outside of the main body, there is a threaded cylinder 10 through a knurl 10c and an adhesive part 9. is fixed, and the threaded rod 6a of the core chuck 6 is screwed into the threaded hole 10a of the threaded tube 10, and the cosmetic 11 is held in the chuck part 6b provided at the front part of the core chuck 6. There is.

At the rear end of the middle tube 4 enclosing the core chuck 6, a joint tube 7 inserted into the threaded tube 10 is fixed by a caulking portion 4'.

The joint tube 7 has a protrusion 7a provided on the inner periphery of the rear part.
is rotatably and loosely fitted into the annular groove 10b of the threaded barrel 10, and a rectangular opening 7 is provided at the top end located in front of the tip of the threaded barrel 10, as shown in FIGS. 2 and 3.
b and a notch 7c extending from the apex and facing each other, and the threaded rod 6a passing through the opening 7b has a cross section with both opposing sides shaved off, as shown in FIG. a flat threaded portion 6e;
Only the rear end is formed with a stopper portion 6d with a thread left without being cut.

Furthermore, several notches are provided in the protruding portion 7a to facilitate insertion into the annular groove 10b.

When assembling this part, the opening 7b of the joint tube 7 is forced to pass through the stopper part 6d of the core chuck 6 while being expanded using the elasticity of the notch part 7c, and then the stopper part 6d and the flat A threaded rod 6a consisting of a threaded portion 6e having a cross-sectional shape is screwed into the threaded tube 10, and the joint tube 7 is externally inserted into the screw tube 10, and an annular shape is attached to the protrusion 7a of the joint tube 7 and the threaded tube 10. The groove 10b is fitted to make it rotatable.

Thereafter, the middle tube 4 is inserted over the core chuck 6, and the joint tube 7 is fixed to the rear end of the middle tube 4 by the caulking portion 4'.

Furthermore, by providing a notch 4e provided at the rear end of the middle cylinder 4 and a protrusion 7e that fits into this notch on the joint cylinder 7, it is possible to further ensure the prevention of displacement in the rotational direction.

Since the middle cylinder 4 covers the notch 7c of the joint cylinder 7, the notch 7c cannot expand after assembly, so the stopper part 6d closes to the opening 7b.
There's no getting out of it.

The opening 4a at the tip of the middle cylinder 4 is covered with a cylindrical inner stopper 2 which is fixed deep inside the cap 3 with double-sided tape 12 or an adhesive, and is attached to the inner circumferential wall of the inner stopper 2. The provided sealing rib 2a is configured to press and seal the outer circumferential wall of the middle cylinder 4.

Further, the cap 3 is configured to have its opening 3a removably fitted into a relay ring 5, and the relay ring 5 is fixed to an opening 8a of the outer cylinder 8.

Furthermore, a sealing rib 6c that bulges outward is also provided at the opening of the chuck portion 6b to tightly and slidably seal the inside of the inner cylinder 4, and a sealing rib 2a provided on the inner plug 2 is provided.
At the same time, circulation with outside air is blocked to prevent the cosmetic 11 from being diffused.

To explain how to use the container of the present invention having the above-mentioned structure, first remove the cap 3 from the relay ring 5 to expose the inner tube 4, grasp the inner tube 4 with your fingers, and use the other hand to remove the cap 3 from the relay ring 5. When the outer tube 8 is rotated with a finger, the threaded tube 10 is also rotated integrally, while the inner tube 4 is gripped and held still, so the joint tube 7 fixed thereto is also kept stationary. , rotation of the flat threaded portion 6e penetrating into the rectangular opening 7b of the joint tube 7 is prevented, and as a result, the threaded rod 6a
The threaded rod 6a moves forward due to the thread provided in the screw thread and the thread provided in the threaded cylinder 10, and the chuck part 6b moves inside the middle cylinder 4, and the tip of the cosmetic 11 is exposed from the opening of the middle cylinder 4. It is.

When storing next time, the cosmetic 11 can be drawn into the inner tube 4 by rotating the outer tube 8 in the opposite direction to that described above.

Furthermore, during use, if the cosmetic material 11 is consumed and the core chuck 6 is accidentally extended beyond its limit, the stopper 6d of the core chuck 6 may be pressed against the narrowed edge of the rectangular opening 7b of the joint tube 7. This prevents the core chuck 6 from falling off by coming into contact with it.

As described above, according to the present invention, a stopper mechanism is formed by the threaded rod 6a of the core chuck 6 and the rectangular opening 7b of the joint tube 7, and during assembly, the stopper mechanism is formed by the notch 7c. 6d can be easily inserted, the structure is simplified and assembly is facilitated, and the practical benefits are extremely significant.
