When closing the lid, the lid may be pushed down so as to disengage the hook-shaped tips of the first and second engaging protrusions and fit into the spout opening.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

As shown in FIG. 1, the spout 1 of the present invention can be attached to any liquid packaging container C. In the illustrated example, the container C is a Goebelt-tup seal paper container for beverages such as milk and juice, and the spout 1 is attached to a slanted wall C ₁ at the top of the container C. The container may be a rectangular parallelepiped paper container or a container of other shapes.

The spout 1 can be made integrally by injection molding or the like from an elastic synthetic resin such as polyethylene, and as a whole, as shown in Fig. It is composed of a lid 2.
The cylindrical main body 3 is integrally provided with a flanged peripheral edge 4 at its base, and this flanged peripheral edge 4 is brought into contact with and joined to the inner surface of the wall surface _C1 of the container C as shown in FIG. By projecting the cylindrical main body 3 to the outside through a hole provided in the container wall surface _C1 , the spout 1 is connected to the container C1.
mounted on. As shown in FIG. 2, the outer surface of the cylindrical body 3 is provided with protrusions 5 for temporary fixing to the container at a distance from the brim-shaped peripheral edge 4, and the protrusions 5 are provided on the outer surface of the cylindrical body 3 for temporary attachment to the container.
The peripheral edge of the hole _C1 is inserted between the collar-shaped peripheral edge 4 and the protrusion 5.

As shown in Figure 3, the lid 2 is higher on the right side of the figure;
It is slanted so that the left side is lower. The lower end of the lid 2 is integrally connected to the upper part of the cylindrical body 3 by a linear thin section 7. This thin portion 7 constitutes a hinge portion 6 of the lid 2.

On the other hand, a cylindrical portion 8 is integrally formed on the back side of the lid 2 excluding the hinge portion 6. This cylindrical part 8
is highest on the left side of the figure, which causes the lid 2 to tilt as described above. The lower end of the cylindrical part 8 is integrally connected to the upper part of the cylindrical main body 3 via a thin-walled part 9 for separation. The thin section 9 for separation is formed in an arc shape along the upper end of the cylindrical main body 3, and both ends thereof are near both ends of the linear thin section 7 and terminate at a position a little distance therefrom. An engaging protrusion 8a is provided at the highest portion of the cylindrical portion 8 in a protruding manner. The cylindrical portion 8 is formed in such a size that its outer surface is in contact with the inner surface of the cylindrical body 3 and can be fitted into the interior of the cylindrical body 3 .

First and second linear engagement pieces 1 are provided on the outer surfaces of the cylindrical main body 3 and the lid 1 with the hinge portion 6 in between, respectively.
0 and 11 are integrally provided so as to be lined up with the hinge portion 6. Note that the engaging pieces 10 and 11 do not have to be linear. The engaging piece 10 extends diagonally outward and upward, and the distal ends of both the engaging pieces 10 and 11 are formed into a hook shape. The hook-shaped tip of the second engagement piece 11 is formed to face the first engagement piece 10, and the hook-shaped tip of the first engagement piece 10 is formed to face the second engagement piece 10.
A portion is formed facing away from the engagement piece 11. Further, an opening/closing knob piece 12 is integrally formed on the lid 2 on the side opposite to the side where the engaging pieces 10 and 11 are provided. By connecting the knob 12 to the lid 2 in a flexible manner (for example, by making the connecting portion between the knob 12 and the lid 2 somewhat thin), force may not be applied to the knob 12 by mistake. Even if the grip piece is bent, the cutting force will not reach the thin wall portion 9, so opening caused by mischief or the like can be prevented.

Since the spout according to the present invention is constructed as described above, by pulling the knob 12 upward,
The lid 2 is torn away from the cylindrical body 3 of the spout along the thin wall portion 9 to the vicinity of the hinge portion 6, and forms a linear thin wall portion 7.
The spout is opened by rotating the hinge portion 6 formed by the spout upward. In addition, in order to prevent the thin wall portion 7 of the hinge portion 6 from also being torn when cutting the thin wall portion 9, the thin wall portion 9 and the thin wall portion 7 of the hinge portion should not be connected as described above. There is.

As the lid 2 is rotated upward, the hook-shaped tip of the engagement piece 11 provided on the lid engages with the hook-shaped tip of the engagement piece 10 provided on the cylindrical body 3 as shown in FIG. The lid 2 is held open. Therefore, the contents can be poured out easily.

After dispensing the contents from the container, press down on the lid 2 and the cylindrical portion 8 of the lid will open as shown in FIG.
