Description

[Detailed Description of the Invention] The present invention relates to a liquid container such as a thermos flask.

In conventional liquid containers of this type, the beak that constitutes the liquid injection passage that communicates between the inside and outside of the container body is fixedly attached to the main body, and the opening and closing operations of the liquid injection passage are performed using a separate member. This was done by screwing a certain plug or moving the valve up and down. For this reason, there was an inconvenience that the open/closed state of the liquid injection passage could not be easily confirmed from the outside.

In view of the above points, the present invention makes the beak unit horizontally rotatable with respect to the container body, and allows the opening and closing of the spout of the beak unit and the opening and closing of the inlet opening of the liquid injection passage in the beak unit. The purpose of this is to make it possible to link the liquid injection passage and to easily know the open/closed state of the liquid injection passage by the rotational posture of the beak unit.To achieve this purpose, there is a A beak unit equipped with a liquid injection passage that communicates between the inside and outside of the container body is provided so that the position of the spout at the outer end of the liquid injection passage can be changed by horizontal rotation, and the spout at the outer end of the liquid injection passage can be changed in position by horizontal rotation. A closing part is provided to close the mouth at the conversion position, and further, the opening/closing operation of the spout and the opening/closing operation of the inlet opening at the inner end of the liquid injection passage are linked by horizontal rotation of the beak unit. It features a unique configuration.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Liquid containers according to embodiments of the present invention will be described below with reference to the accompanying drawings.

A first embodiment of the invention is shown in FIGS. 1-3.

In the figure, the container main body (hereinafter simply referred to as the main body) indicated by the reference numeral 1 has an outer case 2 forming the outer peripheral surface and a liquid container 3 made of a vacuum double bottle forming the inner peripheral surface at their upper and lower parts. It is constructed by integrally connecting a lower mouth member 4 and a bottom member 5.

A handle 6 for tilting the main body is provided on one side of the main body 1 and extends integrally from the lower opening member 4.

A stopper 8 for sealing the liquid supply port 7 into the liquid container 3 is removably screwed onto the lower opening member at the top of the main body 1 .

A beak unit 9 having a liquid injection passage 10 communicating between the inside and outside of the main body 1 is provided on the stopper 8 so as to be horizontally rotatable. That is, a rotatable cylinder 13, which is vertically disposed at the center of the beak unit 9, is forcefully fitted into a receiving cylinder 12, which is protruded from the center of the upper surface of the plug body 8, so as to be freely rotatable.

The outer end of the liquid injection passage 10 is a spout 11, and the spout 11 can be changed in position from the side opposite to the handle to the side of the handle by horizontal rotation of the beak unit 9. .

The inlet opening 10a at the inner end of the liquid injection passage 10 is connected to the communication hole 14 formed in the stopper 8, and the spout 11
The polymerization or non-polymerization state occurs as the position of the material changes to the side opposite to the handle or to the handle side. Reference numeral 15 is a gasket interposed between the beak unit 9 and the stopper 8 to seal the periphery of the inlet opening 10a of the liquid injection passage 10 and the communication hole 14.

Further, the spout 11 is opened downward.

Further, the stopper 8 is integrally provided with a protruding closing portion 16 that overlaps the upper portion of the handle 6 and closes the spout 11 at the converted position. The closed part 1
6 is integrated into the main body 1 side with a plug 8 screwed onto the main body 1.

This closing portion 16 is provided with a positioning protrusion 17 . Instead of the protrusion 17, a ball supported by a spring may be used for positioning.

Next, the operation of the liquid container of the first embodiment will be explained.

As shown in FIGS. 1 and 2, when the spout 11 is positioned on the side opposite to the handle, the spout 11
Of course, the inlet opening 10 of the liquid injection passage 10 is opened.
a is also overlapped with the communication hole 14, and the handle 6
By holding the main body 1 and tilting it toward the spout 11, the liquid inside the main body 1 can be poured out.

Then, when the beak unit 9 is horizontally rotated to change the position of the spout 11 to the handle side as shown in FIG. At the same time, the inlet opening 10a of the liquid injection passage 10 is in a non-overlapping state with the communication hole 14 of the stopper 8. Therefore, the liquid in the main body 1 cannot be poured out, and the intrusion of dirt, insects, etc. into the liquid container 3 can be almost completely prevented.

Furthermore, by visually checking the position of the spout 11 (on the side opposite to the handle or on the handle side) from the outside, it is possible to easily know whether the liquid injection passage 10 is open or closed.

Further, when the stopper 8 and the beak unit 9 are unscrewed from the main body 1, the liquid supply port 7 is opened and liquid can be supplied into the liquid container 3.

A second embodiment of the invention is shown in FIGS. 4-6. In this case, the plug body 8 is removably attached to a plug insertion hole 19 in a peripheral wall 18 projecting from the upper surface of the lower mouth member 4 . Further, the beak unit 9 is fitted to the outer periphery of the peripheral wall 18 of the lower mouth member 4 so as to be horizontally rotatable. A communication hole 14 that is polymerized or non-polymerized with the inlet opening 10a of the liquid injection passage 10.
