Below the pouring spout, there is provided a boat-shaped fusion part 2 that is boat-shaped when viewed from the top and is narrow on the left and right. On the outer surface of the boat-shaped fusion part 2, a sink prevention recess (meat stealing) 21 is run sideways so that the surface will not sink due to molding so that the fusion force does not decrease. In addition, ribs 22 that are thin and pointed are provided at the left and right ends, and designed so that no gap is generated at the boundary where the front and back films begin to overlap.

  Above the boat-shaped fusion part 2, there is a flange 10, and a spout 3 is provided at the center. Standing walls 11 are formed on the left and right sides of the spout 3, and the spout surface with the spout rises from the periphery, and has a stepped surface 32. On the opposite side of the stepped surface 32 to the hinge 40, the engaging recess 321. Is provided.

The hinge cap 4 has an inner ring 41 that can be inserted into the spout at the center. Further, there is a cap side wall 42 around the inside of the hinge cap, and when the hinge cap is closed, the periphery of the spout is covered.

As shown in FIG. 4, the tip of the hinge cap opposite to the hinge has a partially cut shape. If a nail or a finger is hooked on the notched portion and the hinge cap 4 is forcibly peeled off, the fragile portion 4210 is broken and the sealing claw 421 is detached and can be opened.
Thus, since the engagement between the sealing claw 421 and the sealing recess 111 is also added and the hinge cap is sealed in a triple manner, it is not unintentionally opened.
Further, even after opening, since there are the locking claw 422, the engaging recess 321 and the protruding ring 411 shown in FIG. 4, the hinge cap is designed to be sufficiently closed.

The pouring stopper used in the present invention is preferably manufactured from a material that can be fused to the film container body, has good compatibility with the contents, and is suitable for long-term storage.
For example, high-pressure low-density polyethylene, linear low-density polyethylene, medium-density polyethylene, high-density polyethylene, polypropylene, ethylene / vinyl acetate copolymer, and the like can be used.
In addition, production can be performed with high productivity using an injection molding machine, a compression molding machine, or the like.

The front film and the back film used for the film container of the present invention use a thermoplastic resin that can be fused to the inner surface side, and there is no problem in any configuration as long as the storability and strength of the contents can be secured.
For example, from the outside
Polyethylene terephthalate / polyethylene,
Polyamide / polyethylene / inorganic oxide vapor-deposited polyethylene terephthalate / polyethylene,
Polyethylene terephthalate / polyethylene / ethylene vinyl acetate copolymer saponified product / polyethylene,
Saponified ethylene vinyl acetate copolymer / polyamide / adhesive resin / polyethylene,
Polyethylene terephthalate / polyethylene / adhesive resin / polyamide / adhesive resin / polyethylene,
Polyethylene terephthalate / polyamide / adhesive resin / polyethylene / aluminum foil / polyethylene,
A general configuration such as
These films can be bonded together using a normal dry lamination machine, an extruder laminating machine or the like, or can be produced using a multilayer inflation molding machine.

The pouring spout of the present invention and the film container fused with the spout are as described above, and the click feeling when closing the hinge cap is very large, and the opening and closing can be clearly conscious. In addition, it is a plug that can confirm virginity with or without sealing nails.
Further, even if an unintended impact such as dropping is applied, the cap is not easily opened and the cap is connected by a hinge, so there is no risk of losing and it can be used for a film container having a small capacity.
In particular, the plug of the present invention can be reduced in size, but the hinge of the hinge cap is provided in a direction perpendicular to the longitudinal direction of the flange with respect to the boat-shaped flange portion of the plug body. I can do it. For this reason, in the case of a rotating cap that is screwed, even if it is a hard and hard-to-open small-diameter plug, this pouring plug is very easy to open. Moreover, since the plug is not opened carelessly, it is a very easy-to-use plug. The pouring plug of the present invention and the film container fused with any plug have great advantages.
