Description

[Detailed description of the invention] The present invention relates to a container for volatile cosmetics, which stores the cosmetics in an excellent airtight sealing mechanism, and
It is an object of the present invention to provide a container having a rotation stop mechanism that prevents cosmetics from being damaged due to erroneous rotation when the cap is attached or removed.

Hereinafter, the gist of the present invention will be explained based on various embodiments shown in the drawings.

Fig. 1 is a vertical sectional side view showing an embodiment of a cosmetic container equipped with the anti-rotation mechanism of the present invention, Fig. 2 is a partially cutaway exploded perspective view showing the main parts thereof, and Fig. 6 is an exploded perspective view of the container. A threaded cylinder 10 is fixed in the outer cylinder 8 forming the outside of the main body via a knurl 10c and an adhesive part 9, and a threaded rod of the core chuck 6 is inserted into the threaded hole 10a of the threaded cylinder 10. 6a is screwed into the chuck portion 6b provided at the front of the core chuck 6, and a cosmetic 11 is held in the chuck portion 6b.

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 the top end located in front of the tip of the threaded barrel 10 has a rectangular opening 7b and mutually opposing positions continuing from the top end, as shown in FIG. A notch 7c is provided in the opening 7b, and the threaded rod 6a passing through the opening 7b has a threaded part 6e having a flat cross section by cutting off both opposing sides as shown in FIG. It is formed of a stopper part 6d with only the end left uncut and a thread left.

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 the protrusion 7a of the joint tube 7 and the annular shape of the screw tube 10 are inserted. 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'.

Since the middle tube 4 also covers the notch 7c of the joint tube 7, the notch 7c cannot expand after assembly, so the stopper portion 6d does not come out from the opening 7b.

The opening 4a at the tip of the inner cylinder 4 is covered and sealed by the inner plug 2 which is inserted and fixed in the cap 3 as will be described later.

The cap 3 has an opening 3a that is detachably fitted into a relay ring 5, and the relay ring 5 is fixed to an opening 8a of an outer cylinder 8.

Further, a bottomed cylindrical inner stopper 2 is fixed to the inner depth of the cap 3 via double-sided tape 1 or adhesive, and a sealing circumferential rib 2a provided on the inner circumferential wall of the inner stopper 2 is attached.
is pressed and sealed against the outer circumferential wall of the middle cylinder 4.

Furthermore, a sealing circumferential 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 middle cylinder 4, and together with the sealing circumferential rib 2a provided on the middle cylinder. Cosmetics 1 by blocking the circulation with outside air
It is designed to prevent the dispersion of 1.

13 are three protrusions provided on the relay ring 5;
As shown in the second figure, it forms a convex shape consisting of a bottle-shaped neck 13a and a bulging portion 13b, and is fitted into a concave groove 14 consisting of a knurl provided on the side of the cap 3, and by engagement with the neck 13a. This prevents the cap 3 from rotating, and the cap 3 is also frictionally engaged by pressure contact with the bulge 13b, thereby preventing the cap 3 from falling off.

To describe how the container of the present invention having the above-mentioned structure is used, first, the cap 3 is removed from the relay ring 5 to expose the middle cylinder 4, and the middle cylinder 4 is removed from the middle cylinder 4.
If you grasp it with your fingers and rotate the outer cylinder 8 with the fingers of your other hand, the threaded cylinder 10 will also rotate integrally, while
Since the middle cylinder 4 is gripped and held still, the joint cylinder 7 fixed thereto is also held still, and as a result, the joint cylinder 7
Rotation of the flat threaded portion 6e penetrating into the rectangular opening 7b is prevented, and as a result, the threaded rod 6
The threaded rod 6a moves forward due to the thread provided in a and the thread provided in the threaded tube 10, and the chuck portion 6b moves within the middle tube 4, exposing the tip of the cosmetic 11 from the opening of the middle tube 4. It is something.

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.

By the way, when trying to remove the cap 3 during use, it is very common to think that the cap 3 is screwed in and try to remove it by turning it, but in the present invention, the concave groove 14 of the cap 3 and the relay ring 5 are Since the cap cannot be rotated due to the rotation of the projection 13, the cap must be removed by pulling.

In the present invention, if the above-mentioned concave groove portion 14 and protrusion portion 13
If the cap 3 does not stop and can be turned, the bottomed cylindrical inner stopper 2 may be stuck inside the cap 3.
Since the sealing circumferential rib 2a is in pressure contact with the outer periphery of the inner tube 4, it is the same as holding the inner tube 4 and rotating the outer tube 8, and the core chuck 6 is advanced by the rotational feeding mechanism, and the cosmetic 11 is There is a risk that the cylindrical inner stopper 2 may collide with the inside of the bottomed cylindrical inner stopper 2 and collapse.

In this embodiment, three convex protrusions 13 are provided, but it goes without saying that only one of them may be convex and the rest may be linear ribs.
Alternatively, all three points may be elongated protrusions that engage with the troughs of the groove portion 14.

Next, in the case of FIG. 3, the concave groove part 14 consisting of a knurl is formed a little deeper from the cap opening, and only the neck part 13a of the protrusion part 13 engages with the knurl concave groove part 14 to prevent rotation. , bulge 13b
is designed to be able to slide by friction.

In the case of the horseshoe-shaped ridge 13c shown in FIG. 4, two elongated ridges 13b, 1 provided on opposite sides of the horseshoe
3b' engages with the concave groove 14, and the horseshoe part 13c slides into pressure contact with the mouth of the cap 3, and FIG. 5 shows the knurled concave groove 14 having a wide groove width d. When there are a plurality of protrusions 13, for example, three as shown in the figure, one of the protrusions 13 collides with the peak 15 forming the groove 14 and connects to the relay ring 5 of the cap 3. Even in such a case, since the groove width d of the concave groove 14 is wide, the cap can easily avoid the peak 15 and fit into the concave groove 14 by slightly rotating the cap. This allows the cap 3 to fit smoothly into the relay ring 5. In this case, the cap 3
Even if there is some play in the rotational direction of the cap in the crowned state, since the rotation is slight, the cosmetic will not advance to the extent that it hits the innermost part of the inner stopper.

As mentioned above, in the present invention, the chuck portion 6b
A sealing circumferential rib 6c provided on the cap 3 and a sealing circumferential rib 2 provided on the inner wall of the bottomed cylindrical inner plug 2 inserted into the cap 3.
A allows the cosmetics to be stored in the inner cylinder 4 in an airtight manner, and even if the user attempts to remove the cap by mistakenly thinking that it is screwed in when removing the cap, the cap and the relay ring 5 are provided with a Since the cap cannot be turned due to the locking mechanism, the feeding mechanism does not operate via the inner stopper 2 which is inserted into the cap 3 and is fixed. Therefore, damage to the cosmetics can be reliably prevented, which is practical. The effect is great.
