In addition, the spout and cap in the above embodiment are as follows.
Although a description has been given of a structure that is screw-fitted, the present invention is not limited to this, and any structure that can be detachably attached may be used.

"Effects of the Present Invention" As is clear from the above description, the present invention has the following effects.

(1) A container body capable of storing fluid, a spout plug mounting part integrally molded on the top plate of the container body and having an L-shaped half cross section and a crimped ring at the upper end, and the spout plug mounting part. a spout plug body formed of a soft synthetic resin material, which is inserted and supported in the spout plug body, and whose outer peripheral portion is fixed by caulking by curling the upper end of the spout plug mounting portion inward in a ring shape; and a spout plug body formed integrally with the spout plug body. When closed, the half cross section is bent into a roughly U-shape and stored inside, and when opened, it is pulled out and becomes a spout. and a cap smaller than the inner diameter of the ring-shaped curled part of the spout stopper attachment part, so even if the spout stopper and the cap are assembled together, the spout stopper cannot be attached to the spout stopper attachment part of the container body. Can be fixed by caulking. Therefore, the spout plug can be installed more easily than the conventional method in which the spout plug body and the cap are separated and the spout plug main body is attached to the spout plug mounting portion.

(2) Due to (1) above, spout plugs can be easily packed and delivered.

(3) The upper end of the spout attachment part, which is integrally formed with the top plate of the container body, is fixed as a caulking ring by caulking the spout body, so the spout can be kept in a sealed state without using a separately formed ring. Can be installed with.

Therefore, the number of parts is small, and manufacturing costs can be reduced.

(4) Since the upper end of the spout plug attachment part is caulked and used as a caulking ring, the caulking condition can be easily checked.

Therefore, when crimping is done using a separate crimping ring as in the past, the crimping ring may shift and the crimping may not be done properly.
It is possible to prevent problems such as difficulty in confirming the state in which the crimping ring has not been sufficiently crimped.

(5) Since the top plate and the spout plug attachment part are integrally molded, it is easier to attach the top plate and the spout plug, compared to the conventional case where they are formed separately and attached together by caulking. It is possible to reliably prevent an accident in which the spout plug attachment part falls off from the top plate even if a large external force is applied to the spout plug or leaks from between the spout plug and the spout plug.
