BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container suitable for containing cosmetics, and more particularly to a cosmetics container in which a refill container filled with cosmetics can be detachably contained in a container body.

[0002]

2. Description of the Related Art In recent years, cosmetic containers have been provided in which a refill container is filled with cosmetics and the refill container is housed in another container body. This cosmetic container uses a refill container manufactured at a low cost and a container body manufactured at a relatively high cost so as to be excellent in design and practical use. When the cosmetic in the refill container is used up, a new (filled with cosmetic) refill container is stored in the container body instead of the same, and the container body is used repeatedly. This has made it possible to realize cost reduction of cosmetic products.

Conventionally, as a cosmetic container of this type, as shown in FIG.
7 to 7 are known (Japanese Patent Publication No.
-24045). As shown in these figures, the cosmetic container B includes an exterior body 21 (see FIGS. 4 and 5) in which a protector 24 is detachably attached to an opening 22a of a bottomed tubular main body 22, and the exterior body 21. A refill container 30 (see FIG. 6) that is removably mounted inside the main body 22 of the body 21 and has its spout 34 side fixed by the protector 24 and is removably attached to the outer body 21. An outer cap 43 (see FIG. 7) corresponding to the outer body 21 detachably attached to the spout 34 of the refill container 30.

In this case, the protector 24 is attached to the main body 22 by providing the screw portion 26 on the outer periphery of the opening 22a of the main body 22 while the protector 24 has an annular main body 24.
The screw portion 25 is provided on the inner peripheral wall of a, and both 25 and 26 are screwed together. Further, the refill container 30 is mounted on the main body 22 by forming a plurality of protrusions 32, 32 ... on the outer peripheral wall 31a of the main body 31 of the refill container 30 and forming a wide groove 33 for positioning with respect to the main body 22. On the other hand, on the inner peripheral wall 2b of the main body 22,
.. which engage with the protrusions 32, 32 ... And also a protrusion 28 which engages with the recessed groove 33. These protrusions 32, 32. This is done by engaging the groove 33 and the protrusion 28.

In the cosmetic container, when replacing the refill container, it is necessary to first remove the protector from the container body, and then remove the refill container from the container body. In this case, according to the cosmetic container B, the screw portion 25 of the protector 24 and the screw portion 26 of the main body 22 need to be unscrewed, and the grooves 27, 27 ...
And the ridges 32, 32 of the ridge 28 and the refill container 30.
Since it is necessary to release the engagement with the groove and the concave groove 33, there is a problem that the workability of exchanging the refill container is not good.

Further, since the outer peripheral wall 31a of the main body 31 of the refill container 30 is provided with a plurality of ridges 32, 32, ... And concave grooves 33, the refill container 30 needs to have a certain thickness. However, there is also a problem that the amount of synthetic resin used in the container increases.

Therefore, as a cosmetics container using a refill container which makes replacement of the refill container simpler and uses a thin wall and a small synthetic resin portion, there is provided a cosmetics container shown in FIGS. 13713). As shown in these figures, the cosmetic container C has a cylindrical outer casing 5
In the cosmetics container in which the refill container 60 is housed in a replaceable manner, the cylindrical outer casing 50 is formed without a bottom,
A plurality of recessed grooves 52, 52 are provided on the inner periphery of the opened upper end of the outer casing 50, screws 54 are provided on the outer periphery of the outer casing 50, and the body of the refill container 60 is thinned. And a cap 80 is detachably attached to the neck portion of the refill container 60, and a plurality of outer circumferences of the body portion 61 of the refill container 60 are engaged with the recessed grooves 52, 52 of the exterior body 50. By providing convex ribs 67, 67, the refill container 60 can be detachably fitted and stored in the exterior body 50, and the refill container 60 is locked by being screwed onto the outer periphery of the mouth portion of the exterior body 50. The holding ring 70 for holding is arranged detachably.

According to the cosmetic container C, when the refill container 60 is replaced, first, the fixing ring 70 is attached to the exterior body 5.
Then, the bottom portion 68 of the refill container 60 is pushed up from below the bottomless outer casing 50. As a result, the convex ribs 67, 67 ...
It is possible to easily detach the used refill container 60 and easily remove the used refill container 60. Further, since the refill container 60 does not need to be provided with a protrusion or the like other than the convex ribs 67, 67, it can be formed thin.

[0009]

As described above, according to the cosmetic container C, when the refill container 60 is replaced, it is easy to remove the refill container 60 from the outer casing 50, but the fixing ring is used. In order to remove 70 from the exterior body 50, it is necessary to unscrew the screw 72 of the fixing ring 70 and the screw 54 of the exterior body 50, and there is a problem that the replacement workability is still not good. Also,
In connection with this, the fixing ring 70 and the exterior body 50 are rotated relative to each other with respect to the other 70,
Since the screws 72 and 54 of 50 are screwed into each other to be attached to each other, the sectional shapes of both 70 and 50 are necessarily limited to circles. Therefore, there is a problem in that the cosmetic container, which is required to be excellent in design, is a great limitation in terms of design.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a cosmetic container which improves the workability of exchanging the refill container and expands the degree of freedom in design creation.
