b and a convex portion 7c provided inside the peripheral side 7b. The bottom member 7 is also attached to the container body 1 by the same adhesive 8 as the shoulder member 6.

Therefore, by rotating the shoulder member 6 or the bottom member 7, the convex portions 6 d and 7 c provided on the respective members can ride on the inclined surfaces at the ends of the concave portions 35 and 37 and can be separated from the container body 1. Thus, when the container is discarded, the shoulder member 6 or the bottom member 7 which is a dissimilar material member can be easily separated.

In the above embodiment, the end of the convex portion in the rotation direction is formed at a right angle, and the concave portion is formed of the central portion and the three inclined surfaces at both ends. As shown, the present invention can be implemented in other configurations.

The recess 42 shown in FIG. 10 (a) has a recess center 42a which is a flat surface recessed from the upper surface of the shoulder 41, one end in the circumferential direction is an inclined surface 42b, and the other end is a right-angled surface. 42c. Therefore, when the shoulder member 40 is rotated, the convex portion 40a is formed.

The concave portion 45 shown in FIG. 10 (b) is one in which the entire concave portion 45 is formed into a concave curved surface by gradually changing the inclination angle of the inclined surface. Therefore, when the shoulder member 43 is rotated, the convex portion 43a has a shoulder portion without a sudden change in resistance.
It will be pushed up to the upper surface of 44 and can be rotated and separated smoothly.

FIG. 10C shows the shape of the convex portion 46a as two inclined surfaces.
The recess 48 is also formed to have a substantially triangular cross section composed of two inclined surfaces 48a. Therefore, when the shoulder member 46 is fitted to the shoulder step portion 47, the convex portion 46a and the concave portion 48 do not shift from each other, and it is possible to eliminate the backlash of the shoulder member or the bottom member during use of the container.

The projection 49a shown in FIG. 10D is formed in a substantially triangular cross section composed of two inclined surfaces 49b similarly to the projection 46a shown in FIG. 10C. The concave portion 51 formed in the shoulder step portion 50 includes a concave central portion 51a formed of a flat surface and right-angled surfaces 51b formed at both ends in the circumferential direction. By making the convex portion 49a and the concave portion 51 in line contact in this manner, it is possible to prevent the dissimilar material member from rising due to a dimensional error in molding and to securely fit the member.

Although the container has both the bottom member and the shoulder member attached to the container main body, the container may have only one member attached. Further, in each of the embodiments, the container body is made of glass, and the shoulder member and the bottom member are formed of a synthetic resin. However, other containers such as a spray can such as a container in which a metal member and a resin member are mixed, or a PET bottle. Needless to say, the present invention can be applied to a container using a different synthetic resin (for example, ABS and polypropylene).

In the above-described embodiment, the convex portion is provided on the dissimilar material member side in view of the problem of the molding accuracy of the glass. However, it is needless to say that the convex portion may be provided on the container body side.

[0040]

According to the present invention, the dissimilar material-attached container according to the present invention can be easily removed when the container is discarded, even if the dissimilar material member is attached with a certain strength. In particular, the container of the present invention has the effect that the dissimilar material member is simply rotated with respect to the container main body, and can be easily removed without requiring another object such as a coin.
