Abstract

PROBLEM TO BE SOLVED: To prevent air from being flowed when beverage is drunk through a suction port, enable beverage to be efficiently drunk through it and further prevent beverage from dripping from the suction port. SOLUTION: A seal member 8 brought into slidable contact with an inner circumferential wall of a suction port 7 for use in opening or closing a flow passage 6d outwardly fitted to a main body segment 6 of the suction port is installed at an outer circumference of the main body segment 6 of the suction port having the flow passage 6d.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a closure for a beverage container provided with a mouthpiece.

[0002]

2. Description of the Related Art In a stopper of a beverage container, a suction plate having a flow path is provided on a top plate of a lid member detachably provided at an opening of the container body so that the beverage in the container can be drunk without removing the lid. In some cases, a mouth main body and a mouth which is fitted to the mouth main body in the axial direction to open and close the flow path are provided.

[0003]

However, in the above-described structure, when the mouthpiece is slid upward to open the flow passage of the mouthpiece main body and the beverage is taken for drinking, the outer peripheral wall of the mouthpiece main body is opened. Air flows in through the gap between the
Inability to drink beverages efficiently. Also, when drinking
The beverage may drip from the gap between the outer peripheral wall of the mouthpiece main body portion and the inner peripheral wall of the mouthpiece portion.

[0004] Accordingly, the present invention provides a stopper for a beverage container, which can prevent the inflow of air when drinking a beverage from the mouth and can drink the beverage efficiently and does not drip the beverage from the mouth. It is intended to provide.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention provides a mouthpiece body having a flow path and an axially fitted outside of the mouthpiece body to open and close the flow path. In a beverage container plug provided with a mouthpiece on a top plate and detachably provided in an opening of the container body, a seal member is provided on the outer periphery of the mouthpiece body so as to slidably contact an inner peripheral wall of the mouthpiece. It is characterized by:

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to a stopper of a thermos bottle will be described in more detail with reference to the drawings. A plug 2 detachably mounted on the upper part of a container body 1 having a heat insulating structure is provided with a suction port 4 capable of stopping water on a top plate 3 and a decompression release valve 5. The mouthpiece 4 comprises a cylindrical mouthpiece body 6 rising from one side of the top plate 3 and a cylindrical mouthpiece 7 fitted externally to the mouthpiece body 6 so as to be movable in the axial direction. Have been.

The mouthpiece main body 6 has a top surface 6 above the cylindrical body 6a.
b, a cylindrical guide 6c is provided at the center, and a through hole is formed around the guide 6c as a flow path 6d. The cylindrical body 6
a retaining stopper 6e of the suction port 7
The suction port 7 moves downward on the outer periphery of the intermediate portion, and the flow path 6d
Each of the holding projections 6f is formed to protrude, and a sealing member 8 having a T-shaped cross section is provided on the outer periphery of the lower part of the holding projection 6f so as to be in sliding contact with the inner peripheral wall of the mouthpiece 7.

The mouthpiece 7 has a through hole 7c in which the guide 6c is inserted at the center of the top surface 7b above the cylindrical body 7a. Further, a protrusion 7d is formed on the inner periphery of the intermediate portion of the cylindrical body so as to engage with the stopper 6e and the holding ridge 6f.

The mouthpiece 7 has the top surface 7b in contact with the top surface 6b of the mouthpiece main body 6, the through hole 7c is closed by the guide 6c, and the inner surface of the top surface 7b is The path 6d is closed, and the protrusion 7d engages with the holding ridge 6f to close the mouthpiece 4. When the mouthpiece 7 is moved upward, the top surface 7b separates from the flow path 6d, and the flow path 6d
Is opened, and the through hole 7c opens apart from the guide 6c. During this time, since the seal member 8 is in sliding contact with the inner peripheral wall of the mouth 7, air flows from between the outer peripheral wall of the mouth main body 6 and the inner peripheral wall of the mouth 7 even if the user sucks the beverage. It is possible to drink the beverage efficiently without dripping, and the beverage does not drip.

[0010]

As described above, the stopper of the beverage container according to the present invention is fitted around the mouth main body having the flow passage in the axial direction on the outer periphery of the mouth main body to open and close the flow passage. A seal member is provided that slides on the inner wall of the mouth so that air can flow in between the outer wall of the mouth body and the inner wall of the mouth even if the mouth is moved upward to drink beverage. Without this, the beverage can be efficiently drunk, and the beverage does not drip from between the outer peripheral wall of the mouthpiece main body portion and the inner peripheral wall of the mouthpiece portion.
