That is, if the pressing of the operation piece 2e is released, the operation piece 2e returns to the initial position before the pressing as shown in FIG.

  Therefore, according to the present invention, it is opened by torsional deformation, and the operation piece 2e is restored toward the initial position by its restoring force, so that it is possible to obtain good operability.

Further, the pier member 2c ₂ according to the present invention is such that the side end portion 2c _{2 (a)} can generate a restoring force against torsional deformation accompanying the rotation (tilting) of the operation piece 2e. For example, in this embodiment, a flat plate extending in the vertical direction (in order to obtain a more efficient restoring force can be obtained with an easy die cutting operation. It is a plate-shaped part.

In addition, in this embodiment, as shown in FIGS. 4 and 5 (particularly FIG. 5), the pier member 2c ₂ is formed in a convex flat plate, and the portion 2c _{2 (b)} protruding upward is operated. While connecting with the lower end of the piece 2e, the part protruded in the left-right lateral direction is connected to the side wall 2c1 _(s) as _a side end 2c2 _(a) . If comprised like this form, the connection margin of the up-down direction (height direction) of the side edge part 2c2 _(a) with respect to the side wall 2c1 _(s) will become small, and the operation piece 2e can be rotated with small force. .

The above is a preferred embodiment of the present invention, but various modifications can be made within the scope of the claims. For example, in this embodiment, the peripheral wall 2b is formed in an annular shape, but the rear end 2e ₂ side of the operation piece 2e can be cut out as in the prior art.

In this embodiment, the operation piece 2e is connected to the side wall 2c1 _(s) via the breakable connecting portion 2g to prevent the operation piece 2e from rotating unexpectedly during transportation. However, the number and layout of the connecting portions 2g are arbitrary. Further, according to the present invention, the connecting portion 2g can be omitted. In addition to tilting the opened container and pouring the contents, the contents can be poured by inserting a straw or the like into the opening.

  The present invention is not limited to containers that store liquid contents, but can also be applied to containers that store semi-liquid, fluid, and solid-liquid mixed contents. As the contents, food and drink are most suitable.
