Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a pump-type liquid container used as a thermos flask, kettle, etc.

(Prior art) In general, in a pump-type liquid container, the liquid in the liquid container provided in the main body is pumped up by an appropriate pump device and led to the outside through a liquid injection passage that communicates between the inside and outside of the liquid container. It is made possible to do so. Therefore, the spout at the tip of the liquid injection passage is usually opened at a position that projects outward from the outer peripheral surface of the main body for reasons of liquid injection operation. However, with such a structure, the spout portion locally protrudes from the outer circumferential surface of the main body, which poses a problem in that it requires a storage space when not in use or is bulky in terms of product packaging.

Therefore, some attempts have been made to solve the above problem by configuring the spout so that it can be moved in and out of the main body by manual operation (for example,
Publication No. 13873). However, in this case, there is a problem in that it is troublesome to operate the spout portion to extend and retract it.

(Purpose of the invention) The present invention has been made in view of the problems pointed out in the above section of the prior art. The purpose is to obtain.

(Means for Achieving the Object) In order to achieve the above-mentioned object, the present invention provides a pump type liquid container in which a liquid injection passage configured to communicate between the inside and outside of the liquid container can be freely retracted from and retracted from the main body. The guide tube operates so that its outer end surface is flush with the outer circumferential surface of the main body when immersed, and the guide tube is inserted into the sideways dispensing tube fixed to the main body so as to be freely retractable. A spout unit is provided, which includes a downward spout pipe extending from the top of the pipe, and a cover member that covers the outside of the downward spout pipe and the guide tube, and the spout unit is biased in the projecting direction by a spring. At the same time, the retracting operation of the spout unit acts to lock the spout unit to the retracted position, and the lock is operated by an operating section that is located at a location independent from the spout unit and can be operated externally. A stopper mechanism is attached that acts to release the lock.

(Function) In the present invention, the following effects can be obtained by the above-mentioned means.

(1) When not in use, by recessing the spout unit into the main body, the protrusion on the outer peripheral surface of the main body can be eliminated.

(2) Simply by releasing the stopper mechanism from the outside, the spout unit will automatically protrude due to the biasing force of the spring, making it ready for liquid injection.

(3) The spout unit is automatically positioned at the retracted position by the locking operation of the stopper mechanism accompanying the retracting operation of the spout unit.
