DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the drawings. FIG. 1 is an explanatory view showing one embodiment of a mouth cap of the present invention and a method of using the same. FIG. 1 (A) is a perspective view, FIG. 1 (B) is a cross-sectional view, and 10 is a container. ,
20 is a mouth cap of the present invention.

The mouthpiece cap 20 of the present invention shown in FIG.
Is inserted into the opening 12 provided on the upper surface of the container 10 and is attached thereto.
1 and a liquid leakage prevention cover 22 provided on the outside thereof, and a straw mounting tube 25 provided on the upper portion of the insertion tube 21.

As shown in FIG. 1B, the insertion tube 21 is a cylindrical body communicating between the inside and outside of the container through the opening 12.
Below this, there is provided a locking ring 26 as a fitting means for fitting inside the container opening 12, so that the mouthpiece cap 20 can be attached to the container 10.

Outside the insertion tube 21, there is provided a cylindrical liquid leakage prevention cover 22 which slightly protrudes outward from the upper end of the insertion tube 21 and then goes downward. The lower end of the liquid leakage prevention cover 22 is a skirt 23 surrounding the opening 12 and in contact with the upper surface of the container, so that even if the contents leak from the opening 12, it does not leak to the outside. .

Above the insertion tube 21, there is provided a straw mounting tube 25 to which a straw for sucking contents can be mounted. The upper end of the straw mounting cylinder 25 has a slightly enlarged diameter and is formed in a trumpet shape. The straw mounting cylinder 25 is for inserting a straw, but also functions as a mouthpiece for directly attaching a mouth to take in contents.

As shown in FIG. 1A, the mouthpiece cap 20 is pushed into the opening 12 from the outside of the container, and the locking ring 26 is locked on the inner side of the container of the opening 12. Can be installed.

The mouth cap 20 is made of a flexible resin such as an elastomer or silicone rubber or natural rubber. By being made of a flexible resin in this way, even if the user puts on the mouth directly, there is no uncomfortable feeling, it is easy to attach to the opening of the container, and the sealing property is good.

As the container 10, a can-shaped container made of any material such as metal, plastic, glass or paper can be used.

FIG. 2 shows an embodiment of the spout of the present invention. As shown in FIG. 2A, a spout cap 120 having substantially the same shape as the spout cap 20 shown in FIG. An overcap 30 provided with a straw-mounting cylinder cover 35 that covers the mouthpiece cap 120 so as to be fitted to the peripheral edge 14 of the upper surface of the container. A top plate 34 having a through-hole 33 through which the straw mounting tube 25 of the mouthpiece cap 120 can penetrate, and a straw mounting tube cover 35 connected to the peripheral portion 32. .

A connection rib 31 is provided around the inner surface of the top plate of the through hole 33 provided in the top plate 34 of the overcap 30.
The connection rib 31 engages with the connection groove 28 provided in the mouthpiece cap 20 to connect them in a liquid-tight manner.

A peripheral portion 32 provided on a peripheral edge of the top plate 34
Has a fitting structure composed of an outer peripheral wall 36 and an inner peripheral wall 38 that can be engaged with each other so as to sandwich the peripheral edge 14 of the upper surface provided with the opening 12 of the container 10.
Can be attached to the container 10.

The overcap 30 is provided with a straw-attached cylinder cover 35 that covers the mouthpiece cap 20. The straw-attached cylinder cover 35 is shown in FIG.
As shown in the figure, the outer peripheral portion 32 is connected to the peripheral portion 32 via a connecting piece 33. In addition, the straw-attached cylinder cover 35 is shown in FIG.
As shown in (B), the inner ring 39 provided on the inner side of the top surface is fixed so as to be inserted into the straw mounting cylinder 25. In addition, the straw mounting cylinder cover 35 may be connected to the top plate 34.

The spout having the straw-mounting cylinder cover 35 is preferable because the container can be sealed when the contents in the container are not consumed at once.

The material of the overcap 30 can be made of a polyolefin resin such as polyethylene or polypropylene, in addition to the same flexible resin as the mouth cap.

FIG. 3 shows another example of the plug of the present invention, and the same reference numerals are given to the same structural parts as those of the plug shown in FIG.

The plug shown in FIG. 3 comprises an insertion tube 21 inserted into the opening of the container 10 and an overcap 30 fitted and mounted on the upper surface of the container. A top plate 34 with 25;
It comprises a peripheral edge portion 32 provided on the peripheral edge of the top plate 34, which can be fitted to the peripheral edge of the upper surface of the container, and a straw mounting cylinder cover 35 connected to the peripheral edge portion 32 via a connecting piece 33.

A connection rib 31 is provided around the inner surface of the top plate of the straw mounting tube 25 provided on the top plate 34 of the overcap 30. The connection rib 31 is connected to the upper edge of the insertion tube 21. And the two are connected in a liquid-tight manner.

The structure of the peripheral portion 32 of the overcap 30 is the same as that shown in FIG. 2. With this peripheral portion 32, the overcap is fitted to the upper peripheral portion of the container.

It is needless to say that a liquid leakage prevention cover similar to that shown in FIGS. 1 and 2 may be provided outside the insertion tube 21. The liquid leakage prevention cover may be provided integrally with the insertion tube 21 so as to be located outside the insertion tube 21, or may be provided inside the top plate 34 of the overcap 30 so as to be located outside the insertion tube 21. May be provided so as to hang down.

[0031]

According to the present invention, since the member having the above structure and attached to the opening of the container is made of a flexible resin when used in the opening of the container, the leakage of the contents from the opening is smaller than that of the conventional product. Be improved. In particular, by employing a structure provided with a liquid leakage prevention cover, leakage is further prevented.
Further, by mounting the straw on the straw mounting cylinder, the contents can be easily taken out from the container, and the convenience is high.
