Description

[Detailed description of the invention] (Industrial field of application) The present invention relates to a tilting liquid container such as a thermos flask, and more specifically to a liquid passage opening/closing mechanism for dispensing liquid in such a tilting liquid container. It is related to.

(Prior art) In conventional tilting liquid containers such as thermos flasks, a screw stopper is generally used as the stopper for opening and closing the liquid supply port, and when dispensing liquid, the entire stopper is turned in the opening direction. Turn the screw to open the liquid passage,
It was used by screwing the stopper in the closing direction after dispensing the liquid. However, when the liquid passage is opened and closed by screwing the stopper in this way, the operation of turning the stopper becomes troublesome.

By the way, instead of the conventional method of opening and closing liquid passages by screwing a stopper, a liquid container has been proposed that adopts a liquid passage opening and closing method called a so-called one-touch stopper (for example, Japanese Utility Model Publication No. 56-53797). . This type of one-touch stopper type liquid container (Jikko 56-
53797), a liquid passage 126 that communicates the inside of the inner container 104 and the liquid guide portion 113 is formed in a stopper 120 that opens and closes the liquid supply port 112, as shown in FIG. A valve body 130 that opens and closes the liquid passage 126 is housed in the valve body 126. When a valve opening operation member 140 provided approximately in the center of the top surface of the stopper body 120 is pressed once, the valve body 130 is moved downward to the valve open position. When the handle 110 is grasped in this state and the liquid container is tilted forward, the liquid in the inner container 104 is transferred to the stopper liquid passage 1.
26 and the liquid guide portion 113 so that it can be poured out from its tip to the outside. When the valve opening operating member 140 is pressed once more, the valve body 130 is unlocked and maintained in the upwardly moving valve closing state by the biasing force of the spring 138. However, in such a conventional one-touch stopper type liquid container, when dispensing liquid, the valve opening operation member 140 is operated to open the liquid passage 126.
There was a problem in that two operations were required: opening the handle 110, then grasping the handle 110 and tilting it, making the liquid pouring operation cumbersome.

(Purpose of the invention) In view of the above-mentioned conventional problems, the present invention has been developed to make it possible to easily perform the opening (valve) operation for dispensing liquid, and also to perform the liquid dispensing operation easily. It is an object of the present invention to provide a tilting liquid container with a tilting liquid injection type.

(Means for Achieving the Object) The present invention seals the liquid supply port of a liquid container main body with a stopper having a liquid passage formed inside, further opens and closes the liquid passage with a valve body, and the liquid container main body In a tilt-injection type liquid container that can be operated by tilting and injecting liquid by grasping a handle provided on the rear outer surface of the stopper, the valve body is opened at a portion of the stopper body where a thumb is positioned while grasping the handle. an operating part of the valve opening operating member is installed, and further comprising an operating member locking mechanism for holding the valve opening operating member in the valve opening operating position between the plug body and the valve opening operating member. It is characterized by:

(Function) In the tilting liquid injection type liquid container of the present invention, the operation part of the valve opening operation member that opens and closes the liquid passage inside the stopper is located at the part of the stopper where the thumb is placed while grasping the handle. Since this is installed, it becomes possible to operate the operating section of the valve opening operating member with the thumb at the same time as gripping the handle when dispensing liquid. In addition, since an operating member locking mechanism is provided between the plug body and the valve opening operating member to maintain the valve opening operating member in the valve opening operating position, the valve opening operating member can be positioned at the valve opening operating position.

The rest of the structure of the tilting liquid container of the second embodiment is almost the same as that of the first embodiment, and the common components are denoted by the same reference numerals. Use explanation.

(Effect of the invention) In the tilting liquid container of the invention, the operating part 41 of the valve opening operating member 40 that opens and closes the valve body 30 is installed at the part of the stopper 20 where the thumb is positioned while grasping the handle 10. Since the handle 10 is
It becomes possible to operate the operating part 41 of the valve opening operating member 40 with the thumb at the same time as grasping the handle 10, and the action of grasping the handle 10 and the operation of operating the operating part 41 of the valve opening operating member 40 can be performed continuously. This has the effect of making it easier to perform a series of operations for pouring out liquid.

Further, since the valve opening operating member 40 is provided with an operating member locking mechanism 50 for holding the valve opening operating member 40 in the valve opening operating position, the operating member locking mechanism 50 positions the valve opening operating member 40 in the valve opening operating position. If the valve opening operating member 40 is held in place, the valve opening operating member 40 will not return to its original position even if the thumb is removed from the valve opening operating member 40, and the liquid container can be tilted and operated with the thumb free. Alternatively, there is an effect that the fingers are less likely to get tired and the liquid pouring operation becomes easier.
