Description

[Detailed description of the invention] The present invention relates to a liquid container such as a thermos flask used for portable or tabletop use. , in a liquid container configured to communicate between the inside and outside of the main body and having a spouting passage opened and closed by a valve body, a stopper is removably tightly fitted therein; The purpose of this is to make it possible to easily open and close the stopper without touching the stopper.

In order to achieve this object, the present invention provides a liquid container having the above structure, in which the spout at the outer end of the spouting path is opened at a position outside the outer surface of the plug and below the bottom surface of the plug. An annular grip portion for screwing in and removing the screw is formed on the upper part of the body, and an operating lever linked to the valve body to open and close the valve body is provided so as to be externally operable, and an operating portion of the operating lever is provided on the stopper body. , it is characterized by a configuration in which the grip portion is located inside the grip portion and is exposed to a lower side than the upper surface thereof.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A liquid container according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

In the following description, a thermos flask is used as an example, but it goes without saying that the present invention can also be applied to electric pots for both heating and heat retention, cold containers, etc. other than thermos flasks.

FIG. 1 shows a portable thermos flask that is an embodiment of the present invention. In the figure, numeral 1 is the container body (hereinafter simply referred to as the main body), 2 is a sheet metal outer case that forms the outer circumferential surface of the main body 1, and 3 is a vacuum double-bottle liquid that forms the inner circumferential surface of the main body 1. A container 4 is a lower opening member made of synthetic resin constituting the upper surface of the main body 1;
6 is a liquid supply port formed in the center of the lower mouth member 4; 6 is a plug body that is removably screwed into the plug insertion hole 8 of the lower mouth member 4 to seal the liquid supply port 5; and 7 is the plug body 6
This is a lid that also serves as a top and is removably screwed onto the outer circumferential surface of the lower mouth member 4 to cover the lower mouth member 4.

A pouring passage 9 is formed in the stopper 6, which serves as a passage for leading out the liquid from the liquid container 3. The pouring passage 9 communicates into the liquid container 3 via a passage 9a provided on the bottom surface of the stopper 6.

The passage 9a is opened and closed by a valve body 10 that is movable up and down with respect to the bottom surface of the stopper 6, and the valve body 10 is always urged in the valve closing direction by a spring 11. Forced. Reference numeral 12 denotes a spring receiver provided on the valve stem 10a of the valve body 10.

On the other hand, a beak portion 13 is interposed at the outer end of the spouting passage 9 and protrudes outward from the side surface of the stopper 6 and is retractable into the spouting passage 9. The tip opening of the beak 13 is a spout 14, and the spout 14 includes:
A self-weight type flap 15 is provided which opens when dispensing and closes when not dispensing. The spout 14 is opened at a position outward from the outer surface of the stopper 6 and below the top surface of the stopper 6, so that the upper part of the stopper 6 can be screwed on and removed. An annular grip portion 16 is formed for use.

Further, an operating lever 17 that slides in the horizontal direction along the top plate 6a of the plug body 6 is disposed within the plug body 6.

The operating lever 17 is used to open and close the valve body 10, and its operating portion 17a protrudes from a window hole 18 formed in the upper surface 6a of the stopper so that it can be operated externally. The operating lever operating portion 17a is located within the gripping portion 16 and faces below the upper surface thereof. By doing so, when the main body falls over, the operating portion 17a
The grip portion 16 prevents external force from acting on the valve body 10, thereby preventing hot water or the like from flowing out due to the inadvertent opening of the valve body 10.

A cam 17b is formed on the lower surface of the operating lever 17. The cam 17b engages with the upper end of the valve stem 10a of the valve body 10 and acts to press the valve body 10 in the valve opening direction.

In this embodiment, the operating lever 17 is integrally formed with the beak portion 13, and the operating lever 17 slides in the valve-opening direction (i.e., slides in the direction of arrow A).
The beak 13 can protrude outward from the side surface of the stopper main body 6 in accordance with the condition. The amount of protrusion d of this beak 13
is designed to such an extent that it cannot allow the lid body 7 to be screwed onto the lower mouth member 4.

Next, the operation of the thermos flask shown in FIG. 1 will be explained with reference to FIG. 2.

FIG. 1 shows the state of this thermos flask when carried, with the valve body 10 closed and the beak 13 retracted, making it impossible to pour.

When pouring liquid from this thermos flask, after removing the lid 7, move the operating part 17a of the operating lever 17 in the direction of arrow A, and move the cam 1
7b is engaged with the upper end of the valve stem 10a of the valve body 10. Then, as shown in FIG.
At the same time when the valve is opened by being pushed down by b, the beak part 13
protrudes outward from the side of the stopper 6, making it ready for pouring.

Note that under this system, the beak 13 becomes an obstacle and the lid 7 cannot be screwed into the lower mouth member 4.
Therefore, it is possible to prevent liquid leakage accidents caused by carrying the valve body 10 in an open state.

When supplying liquid to this thermos flask, the cap can be easily opened by holding the grip part 16 on the top of the cap 6, and at that time, the spout 14 is not touched by fingers, which is very hygienic.

Next, the effects of the liquid container of the present invention will be listed below.

(1) Outlet 1 at the outer end of the outlet channel 9 formed in the plug body 6
4 is opened at a position outward from the outer surface of the plug 6 and below the top surface of the plug 6, and an annular grip portion 16 for screwing in and removing the screw is formed at the top of the plug 6. It is possible to easily open and close the spout 14 without touching the spout 14 with fingers or the like, and it is hygienic and easy to use.

(2) Since the spout 14 of the spout channel 9 is opened outward from the outer surface of the stopper 6, during the spouting operation,
Water drains well and pouring can be performed smoothly.

(3) An operating lever 17 linked to the valve body 6 to open and close the valve body 10 is provided so as to be externally operable, and the operating portion 17a of the operating lever 17 is located within the grip portion 16 from the upper surface thereof. Since the lower part is located at the bottom, the opening and closing operations of the valve body 10 can be easily and reliably performed, and the grip part 1 prevents external force from acting on the operating part 17a when the main body falls over.
6, it is possible to prevent hot water or the like from flowing out due to the inadvertent opening of the valve body 10.
