Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic container in which an inner container filled with a cosmetic such as a lotion or a liquid foundation is replaceably housed.

[0002]

2. Description of the Related Art A relatively inexpensive inner container filled with cosmetics is replaceably attached to an expensive exterior container with a beautiful design, and when the contents are used up, a new inner container filled with cosmetics is replaced. BACKGROUND ART Cosmetic containers in which an outer container is continuously used are well known. As a conventional container of this type, for example, a cosmetic container shown in FIG. 5 disclosed in Japanese Patent Publication No. 4-24045 has been proposed.

This conventional cosmetic container has a decorative cover 51.
The inner container 5 that can be freely inserted into and removed from the outer container body 51 decorated with a
The neck of the inner container 52, which is attached to the outer container body 51, is fitted with a shoulder cover 53 that prevents the inner container 52 from slipping out of the outer container body 51 and is screwed over the opening of the outer container body 51. It is configured by fitting a lid 54 to 52a.

Since the inner container 52 in this conventional container has a circular cross-sectional shape, the protrusions 56 provided on the outer peripheral surface of the inner container 52 are engaged with a plurality of groove grooves 55 provided inside the outer container body 51. The inner container 5 inside the outer container body 51 is aligned with the inner and outer containers by interlocking with each other to prevent rotation.
The rattling in the vertical direction of 2 is regulated and prevented by tightening the shoulder cover 53.

In the cosmetic container, when the inner container 52 is replaced, the shoulder cover 53 is attached to the outer container body 5.
Since the shoulder cover 53 is screwed into the outer container body 1, it is troublesome to attach and detach the shoulder cover 53, and when the inner container 52 is mounted on the outer container body 51, the ridge 56 of the inner container 52 and the groove 55 of the outer container body 51. However, there is a problem in that the operability of replacing the inner container 52 is not good.

Further, since the inner cover 52 is fixed by pressing the shoulder portion 57 of the inner container 52 by tightening the shoulder cover 53, if the inner container 52 has a large dimensional variation, the inner container 52 will be the outer container. The shoulder cover 53 hits the shoulder portion 57 of the inner container 52 and cannot be completely tightened, and a gap is formed at the lower end portion of the shoulder cover 53, which makes it unsightly. Therefore, a high dimensional accuracy is required for manufacturing the inner container 52, and an inexpensive hollow bottle molded by direct blow using a general-purpose synthetic resin material such as polyethylene or polypropylene has a large variation in height dimension, which makes it difficult to adopt. However, there is a problem that an expensive inner container 52 having high dimensional accuracy must be used.

Further, for example, JP-A-7-303517 and JP-A-7-315414 disclose cosmetic containers that solve the above problems. However, these cosmetic containers are limited to cosmetic containers whose cross-sectional shape is oval or polygonal, which does not require rotation prevention and alignment between the inner and outer containers, and the cross-sectional shape is circular. It is not possible to configure.

[0008]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and improves the operability when exchanging the inner container, relaxes the dimensional accuracy, and reduces the cross-sectional shape of the inner container. An object is to be able to configure any shape such as a circle, an ellipse, and a polygon.

[0009]

SUMMARY OF THE INVENTION According to the present invention, an inner container having a pair of vertical grooves sandwiching a neck portion on the periphery of a shoulder, and the inner container being removably housed and having a pair of recesses in an opening. A cylindrical outer container body opened opposite to each other, and a shoulder cover detachably hung on the inner container and detachably attached to the opening of the outer container body; A tongue piece is vertically provided on the outer peripheral edge of the shoulder cover to prevent the mutual rotation of the shoulder cover and the outer container body and the vertical groove is formed on the back surface of the tongue piece. A vertical rib that engages with and prevents the inner container from rotating is provided so as to solve the above problem.
