Description

[Detailed Description of the Invention] Industrial Technical Field The present invention relates to the structure of a stopper for a liquid container such as a magic bottle, and particularly relates to the structure of a stopper for a liquid container such as a magic bottle. This relates to the structure of the stopper that can be created.

BACKGROUND ART Conventionally, in a stopper for a liquid container such as a magic bottle, a liquid flow path is provided in the stopper, a valve is provided in the liquid flow path so that the valve can be opened and closed from the outside, and the stopper is removed from the liquid container. A device is known that allows the liquid content to be poured out without removing it.

Problems to be Solved by the Invention However, in the above-mentioned conventional stopper, although the valve is provided in the stopper body, the sprue is provided in the liquid container body, and the content liquid passes through the liquid flow path of the stopper body. The liquid is poured out through a spout formed in the container body. Therefore, the sprue always protrudes from the liquid container body, which often gets in the way when it is being carried around.

The present invention was devised in view of the above circumstances, and the sprue is provided in the stopper, the sprue is normally housed within the stopper, and the sprue is made to protrude from the liquid container at the same time as the valve is opened or closed.

Means for Solving the Problems Accordingly, the present invention provides a sprue sliding chamber in the upper part of the plug body, forms a liquid flow path and an air vent hole leading from the inside of the liquid container to the sprue sliding chamber, and An annular packing is fitted to the bottom of the chamber surrounding the liquid flow path and the air vent hole, and the sprue sliding chamber has a sprue member having a sprue at the tip and a liquid passage hole drilled on the bottom surface. It is characterized by being able to slide freely back and forth.

Embodiment The drawings show an embodiment of the present invention.
This figure shows a magic bottle to which the stopper of the present invention is applied.

Reference numeral 1 denotes a magic bottle body, in which a vacuum double bottle 2 as an inner bottle is housed, and a stopper 3 is screwed onto the top. The plug body 4 has a sprue sliding chamber 5 at the top.
, and a liquid flow path 6 communicating from the bottom of the sprue sliding chamber 5 into the main body 1 of the magic bottle is formed. In this embodiment, the upper half of the liquid flow path 6 is inclined forward. Also, an air vent hole 7 is bored from the middle of this liquid flow path 6 to the bottom surface of the sprue sliding chamber 5, and the bottom surface of the sprue sliding chamber 5 has the following features:
An annular gasket 8 is fitted around the air vent hole 7 and the upper end opening of the liquid flow path 6.

Reference numeral 9 denotes a sprue member housed in the sprue sliding chamber 5 so as to be slidable back and forth. The sprue member 9 has a substantially rectangular shape with a flat cross-section and a cylindrical shape with a sprue 10 open at the tip. A liquid passage port 11 is bored in the bottom surface of the sprue member 9, and a knob 12 is protruded from the top surface. An air vent hole 13 is bored at the end.

When the sprue member 9 slides backward, the liquid passage port 11 is located outside the gasket 8, and the sprue 10 is housed within the plug body 4. When the sprue member 9 slides forward, as shown in FIG. As shown in FIG. 2, the liquid passage port 11 is located at the opening at the upper end of the liquid flow path 6 provided in the plug body 4, and the sprue 10 projects from the plug body 4. A flap 14 is swingably provided at a position on the plug body 4 facing the sprue 10.

Function: According to the present invention, first, the sprue member 9 is always slid backward and housed within the plug body 4, and the flap 10 is swung downward. Further, the liquid passage port 11 is located outside the packing 8, and the liquid passage 6 of the plug body 4 is sealed between the bottom surface of the sprue member 9 and the packing 8, and the liquid passage 6 and the liquid passage port 11 do not communicate with each other. Therefore, the magic bottle main body 1 is in a sealed state, and the liquid content will not leak out even if it falls over.

Next, when the knob 12 is pressed and the sprue member 9 is slid forward, the tip of the sprue member 9 is pushed into the flap 14.
is pushed open, the sprue 10 protrudes from the stopper 4, and the liquid passage port 11 coincides with the upper end of the liquid flow path 6. Therefore, when this magic bottle is tilted, the liquid content flows from the liquid flow path 6 through the liquid passage port 11 into the sprue material 9, and can be poured out from the protruding sprue 10. Furthermore, air flows into the magic bottle main body 1 through the air vent holes 13 and 7, allowing smooth dispensing of the contents.

Effects of the Invention According to the present invention, the sprue 10 is provided in the sprue member 9, and the sprue 10 is housed in the plug body 4 when the sprue member 9 is slid backward.
Therefore, the sprue 10 does not protrude from the plug body 4, and the sprue 10 does not get in the way when handling the magic bottle, and the design of the liquid container is not restricted by the sprue, making it easy to clean. be excellent. Further, the open/closed state of the plug 3 can be easily determined based on whether or not the sprue 10 protrudes from the plug body 4, and no special means for determination is required. Furthermore, the structure is simple and can be provided at low cost. Also, according to the present invention,
Since the air vent hole 7 communicates with the liquid passage port 11,
Even if the liquid content leaks from the air vent hole 7 during dispensing, etc., it will be mixed with the poured content liquid and will not wet other parts, and the air vent hole 7 will not be exposed to the outside, so it will not get dirty. It is hygienic.

Further, as shown in the embodiment, by slanting the upper part of the liquid flow path 6 in the direction of the sprue 10, the streamline of the liquid content curves gently when pouring out the liquid content, allowing smooth pouring.
