The shoulder 12 has a diameter smaller than the outer diameter of the container body 1, and a step is formed between the shoulder 12 and the outer periphery 13. Most of the upper surface of the outer peripheral portion 13 is formed as a horizontal contact surface 14a which coincides with the rotation direction of the shoulder member 2, and a part of the upper surface is retracted to the bottom side of the container body 1. The recessed portion is formed with inclined surfaces 14b on both sides such that both sides become narrower toward the bottom, and a bottom surface 14c parallel to the horizontal contact surface 14a is formed at the lowermost portion. The horizontal contact surface 14a, the inclined surface 14b, and the bottom surface 14c together form the contact surface 14 on the container body 1 side.

The shoulder member 2 includes a top plate 20 having a circular shape equal to the cross section of the container body 1 and a peripheral side surface 22 erected around the top plate 20.
It is composed of A hole 21 for inserting the neck 11 is opened in the center of the top plate 20, and a rib 23 having a predetermined height is provided inside the hole 21.

The contact surface 24 which is the lower surface of the peripheral side surface 22 is formed in a shape corresponding to the contact surface 14 on the container main body 1 side, and an inclined surface 24b is provided beside the projecting portion 2a, and a bottom surface 24c is provided below the projecting portion 2a.
Is formed on the horizontal contact surface 24a except for the protruding portion 2a.

The shoulder member 2 is made of a synthetic resin such as polypropylene and has elasticity. By strongly inserting the neck portion 11 into the hole 21, the rib 23 is elastically deformed and the locking projection 23a engages with the flange 11a. I do. As a result, when the shoulder member 2 is attached to the container body 1 as shown in FIG. 3, the contact surface 14 on the container body 1 and the contact surface 24 on the shoulder member are in contact all around. In addition, the two are fitted integrally in design without a gap in appearance.

Next, an operation for separating the shoulder member 2 which is a dissimilar material from the container A constructed as described above from the container main body 1 will be described. When the shoulder member 2 is rotated as shown in FIG. 4, the inclined surface 24b of the contact surface 24 of the shoulder member 2

The lower surface of the peripheral side surface 22 of the shoulder member 2 is also formed in a shape corresponding to this, and includes a horizontal contact surface 24a and an arc contact surface 24e.

Therefore, by rotating the shoulder member 2, the arc contact surface 24 e of the shoulder member 2 is changed to the arc contact surface of the emblem 15.
15a, and as a result, the shoulder member 2 is
It can be more separated. By forming the protruding portion in an arc as described above, the resistance is large when the rotation of the shoulder member 2 is started, and the resistance gradually decreases as the rotation is performed. Therefore, it is possible to prevent the shoulder member 2 from rotating carelessly.

In the container A shown in FIG. 8, the shoulder member 2 is provided with an arc-shaped projection 2c. The container body 1 has an arc contact surface 14 corresponding to the arc contact surface 24f of the protrusion 2c.
e is formed, and when the shoulder member 2 is fitted to the container main body 1, the appearance of the container A is integrally designed.

Further, by making such arc-shaped projecting portions intersect and be continuous, as shown in FIG.
f and 24g draw a waveform. Thereby, the shoulder member 2
