Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention consists of a case body that covers the outer peripheral surface of a liquid container, and a liquid in the container from the upper side of the container by pressurizing air into the liquid container. an air pump for sending out of the container and its manual operation member; a liquid injection pipe for guiding the liquid sent out of the container by the air pump downwardly outside the case main body; and a cover for covering the liquid injection pipe.

[Conventional technology]

The above-mentioned liquid storage container with an air pump is equipped with a manually operated air pump that sends the liquid inside the container out of the container from the top of the container, so it is possible to pour the desired amount of stored liquid without tilting the entire liquid storage container. In addition to being easy to take out, it is also equipped with a liquid injection pipe that guides the liquid sent out of the container by operating the air pump to the bottom of the case body, so it can be used in liquid storage containers that do not have such a liquid injection pipe (for example, an actual liquid container). 1977

49-139656), even if you operate the pump with a container such as a pot placed at almost the same height as the surface of the liquid storage container, the liquid will not splash up or
The desired amount of liquid is delivered in a state where there is little variation in the drop position of the liquid to the container during pump operation, and the liquid is unlikely to fall outside the container, in other words, there is little risk of wasting the liquid or contaminating the surrounding area. It has the advantage that it can be easily taken out.

Furthermore, a through hole is formed in the bottom of the container, and a liquid guide pipe equipped with an on-off valve is connected to the through hole,
A type of liquid storage container without an air pump that takes out the liquid by gravity flowing through the liquid conduit (for example, Japanese Utility Model Application Publication No. 59-93353, Japanese Utility Model Application No. 57)
-Refer to Publication No. 169237, Publication No. 145440 of Japanese Utility Model Publication No. 1983)
This method is advantageous in that it is easier to avoid inconvenient situations such as the stored liquid gradually leaking out from the connection point of the liquid guide pipe.

In addition, since the bulky but lightweight air pump is installed above the outer surface of the liquid container, liquid containers with the air pump installed below the liquid container (for example, Utility Model No. 50-98371) The center of gravity of the liquid container as a whole is lower than that of the liquid storage container (see Japanese Patent Publication No. 2003-111002), and there is an advantage that overturning moment is less likely to occur especially when operating the air pump manually, and it can be operated in a relatively stable posture.

Conventionally, a thermos flask, which is an example of the above-mentioned liquid storage container equipped with an air pump, has such advantages. It is known that the upper cover is provided with a manual operating member for compressing the air and a safety stopper for restricting the operation of the manual operating member (for example, Utility Model Application No. 181341/1983, No. 112734/1983). (see official bulletin).

[Problem that the invention attempts to solve]

However, in order to operate the operating member and safety stopper, it is necessary to extend your hand from a high position above the top cover, and it is difficult to operate the operating member and safety stopper from diagonally above the liquid container. This method has the disadvantage that a large overturning moment is generated and the posture of the liquid container tends to be unstable.
This device has the advantage that the liquid is unlikely to fall to the outside of the container even if you operate the air pump with the container placed on the same surface as the liquid storage container without holding it with one hand. However, operating the air pump requires a large movement, and since the operating position of the air pump and the position where the liquid falls from the injection pipe are far apart, it is difficult to know how the liquid is falling into the container and the amount taken out. The problem was that it was difficult to operate the manual operation member and safety stopper accurately while monitoring the system, and the overall operability was poor.

The present invention was developed in view of the above-mentioned circumstances, and by devising the mounting structure of the air pump, its manual operation member, and the safety stopper, it is possible to avoid increasing the size of the entire liquid storage container.
The purpose of the present invention is to provide a liquid storage container with an air pump that has excellent operability.

[Means for solving problems]

The characteristic structure of this invention to achieve the above purpose is as follows:
In the above-mentioned liquid storage container with an air pump, the air pump is provided inside the case body outside the shoulder of the liquid container, and an interlocking member that operates the air pump in conjunction with the vertical operation of the manual operation member. a safety stopper extending to the cover side and switching the manual operating member between a locked state that prevents the manual operating member from moving to the liquid pouring operation position and an unlocked state that allows the movement; The cover is mounted in a position facing the outside of the manual operation member, and a vertically long guide surface is formed on the cover to guide the vertical movement of the manual operation member.This structure provides the following effects.

[Effect]

(b) Since the air pump is installed inside the case body on the outside of the shoulder of the liquid container, the center of gravity of the entire liquid storage container is higher than if a relatively lightweight air pump were placed at the bottom of the case body. The manual operation member and the safety stopper of the air pump can be mounted at a relatively low position on the side of the case body, rather than at a high position on the upper side of the case body, while avoiding the risk of causing problems.

(b) By effectively utilizing the cover of the liquid injection pipe protruding from the side of the case body, an interlocking member that operates the air pump in conjunction with the operation of the manual operation member is installed on the cover side, and a safety stopper is installed. Since the manual operation member is mounted in a position facing the outside of the cover, there is no need to provide a separate space for installing the safety stopper, manual operation member, and interlocking member, which means that the entire liquid storage container can be made larger. The safety stopper and the manual operation member can be installed in a position close to the liquid injection pipe without having to do so.

(c) If the manual operation member is configured to be operated by sliding laterally along the cover, the cover needs to be long in the horizontal direction, which increases the size of the cover and prevents liquid from flowing when the manual operation member is operated. If you do not hold the container with one hand,
Although there is a risk that the entire liquid storage container may shift laterally, the relatively long vertically long cover that covers the liquid injection pipe can be effectively used to operate the manual operation member vertically along the cover. Since the cover is formed with a vertically long guide surface that guides the vertical movement of the manual operation member, the manual operation member can be attached without increasing the size of the cover, and the liquid container can be opened with one hand. You can operate the manual operation member in a comfortable posture without having to hold it.

(d) Since the safety stopper and manual operation member are mounted in a position facing the outside of the cover, a series of operations such as unlocking the safety stopper, operating the manual operation member, and locking the safety stopper can be performed in a small manner. The operation can be done rationally, and the switching position of the safety stopper can be easily confirmed.

[Effect of idea]

Due to the effects of (a) and (d) above, a series of operations on the safety stopper and the manual operation member can be performed rationally with small movements while maintaining a stable posture that does not cause a large overturning moment when operating the manual operation member. I can do it.

Due to the effects of (b) and (d) above, the entire liquid storage container does not need to be enlarged, and the safety stopper,
Manual operation members and devices such as tips can be easily monitored and operated accurately.

Due to the effect of (c) above, the manual operation member can be operated in a comfortable posture without increasing the size of the liquid injection tube cover.

Therefore, it has become possible to provide a liquid storage container with an air pump that has excellent operability without increasing the size of the entire liquid storage container.
