  Hereinafter, various forms of the stopper cap according to the present invention will be described in detail with reference to the drawings.

  FIG. 1 shows a hinge-type cap (hereinafter referred to as “hinge cap”) 10 according to a first embodiment of the present invention. The hinge cap 10 is entirely made of synthetic resin.

  In FIG. 1, reference numeral 11 includes a mounting cylinder 12 fixed to a mouth part (hereinafter referred to as “container mouth part”) 51 of a container 50 and a dispensing cylinder 13 leading to a bottle container (hereinafter referred to as “container”) 51. The main body is provided with a plug 15 that can be removed from the top wall 14 on the top wall 14 that closes the inside of the pouring tube 13.

  The mounting cylinder 12 has an outer cylinder 12a and an inner cylinder 12b, and the container mouth 51 is fitted into an annular groove G formed between the outer cylinder 12a and the inner cylinder 12b. 51 is fixed.

  More specifically, an annular protrusion 12c is provided on the inner peripheral surface of the outer cylinder 12a. The annular protrusion 12 c is locked to an annular protrusion 52 provided on the outer peripheral surface of the container mouth portion 51. On the other hand, the outer peripheral surface of the inner cylinder 12b is in close contact with the inner peripheral surface of the container mouth portion 51, thereby sealing the container mouth portion 51 in a liquid-tight state.

  The plug body 15 has a pull ring 15 a for hooking a finger, and a main body portion 15 b is formed by a thin cutting line L formed on the top wall 14. When the finger is hooked on the pull ring 15a and then pulled up as it is, the main body portion 15b is cut off along the planned cutting line L. As a result, a spout formed by the planned cutting line L is formed in the top wall 14.

  Furthermore, the main body 11 is connected between the mounting cylinder 12 and the extraction cylinder 13 by an annular partition wall 16 that can be bent and deformed. In this embodiment, the partition wall 16 has a dome shape that decreases in diameter while being curved from the inner cylinder 12 b toward the extraction cylinder 13, and is connected to the extraction cylinder 13. Thereby, the partition wall 16 is comprised so that it may be easy to produce the bending deformation between the mounting cylinder 12 and the extraction pipe | tube 13. As shown in FIG. According to the present invention, the partition wall 16 has a tapered shape that is reduced in diameter while being inclined at a certain angle from the inner cylinder 12 b toward the extraction cylinder 13, and is connected to the extraction cylinder 13. The same is true.
