Description

Detailed Description of the Invention [Industrial Field of Application] The present invention includes a case body that covers the outer peripheral surface of a liquid container, and a case body that is installed above the outer surface of the liquid container to allow air to flow into the liquid container. An air pump that sends liquid inside the container out of the container from the upper side of the container by press fitting, and its manual operation member, and a liquid injection member that guides the liquid sent out of the container by the air pump to the lower part of the case body. The present invention relates to a liquid storage container with an air pump that includes a pipe and a cover that protrudes from the side surface of the case body and covers 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. Although it is easy to take out, 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 this through hole, and the liquid flows under its own weight through this liquid guide pipe. A type of liquid storage container without an air pump to take out the liquid (for example,
93355 (see Publication No. 93355), it has the advantage that the stored liquid will not gradually leak out from the connection point of the liquid conduit pipe, and the liquid that is sent out of the container by the operation of the air pump. Since it is equipped with a liquid injection pipe that guides the liquid downward into the case body, liquid storage containers without such a liquid injection pipe (for example,
Publication No. 13263, Publication No. 49-143255, Publication No. 143255, Publication No. 143255, Publication No. 143255
50-63655, Japanese Utility Model Application Publication No. 50-54663, and Japanese Patent Application Publication No. 50-65906), the container such as a gop is placed at almost the same height as the mounting surface of the liquid storage container. Even if you operate the pump by using the pump, there is little splashing of the liquid or fluctuation in the position of the liquid falling into the container during pump operation, and the liquid is unlikely to fall to the outside of the container, which means that the liquid is not wasted. It has the advantage of being able to easily take out the desired amount of liquid with little risk of contaminating the surrounding area.Furthermore, the air pump, which is bulky but lightweight, is installed above the outer surface of the liquid container. A liquid storage container with a pump installed below the liquid container (for example,
50-98371), the center of gravity of the entire liquid storage container is lower, and the advantage is 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. be.

As shown in FIG. 13, a conventional thermos flask, which is an example of the above-mentioned liquid storage container with an air pump, has such advantages, and air is pressurized into the liquid container through the upper side of the case body, that is, the top lid B of the container. It is known that an air pump P is housed inside, and a cylindrical manual operation member 01 for compressing the pump P is fitted in a recess 02 formed on the upper surface of the upper cover so as to be vertically movable. .

[Problem that the invention seeks to solve]

However, in order to move the operating member 01 up and down, the operating member 01 must be inserted into the recess 02 of the upper cover B by extending your hand from a high position above the upper cover B.
must be recessed into the upper lid B, and when operating the operating member 01 from diagonally above the liquid container, a large overturning moment is generated and the posture of the liquid container tends to be unstable. Even if you operate the air pump P with the container placed on the same surface as the liquid storage container without holding it with one hand, the liquid is unlikely to fall to the outside of the container. The operation of the pump P requires a large movement, and since the position of the operating member 01 of the air pump P 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. There was a problem in that it was difficult to use the operating member 01 accurately while monitoring the operation member 01, and the overall operability was poor.

The present invention has been made in view of the above-mentioned circumstances, and by devising the mounting structure of the air pump and the manual operation member thereto, the present invention achieves excellent operability without increasing the size of the entire liquid storage container. The object of the present invention is to provide a liquid storage container with an air pump.

[Means for solving problems]

The characteristic structure of the present invention for achieving the above object is as follows:
In the above-mentioned liquid storage container with an air pump, the air pump is provided in the case body, a swinging member for operating the air pump is provided, one end of which extends toward the cover side, and the swinging member A swingable manual operating member that swings by pressing one end of the member is pivotally supported on the cover, and this configuration provides the following effects.

[Effect]

(a) Since the air pump is provided inside the case body, the manual operation member in the through hole can be mounted at a low position on the side of the case body, rather than at a high position on the upper side of the case body.

(b) A manual operation in which one end of the swinging member that operates the air pump is extended to the cover side, making effective use of the cover of the liquid injection pipe protruding from the side of the case body, and the swinging member is operated. Since the components are attached to the cover, there is no need to provide separate space for attaching manual operation components and swinging components.
In other words, the manual operation member is mounted at a position close to the liquid injection pipe without increasing the size of the entire liquid storage container.

(c) If the manual operation member is configured to slide along the cover, the cover will need to be long in the sliding direction, which may increase the size of the cover. Since the operating member is configured to be swingable and pivotally supported on the cover, there is little risk that the cover will become large.

(d) If the manual operation member and the swinging member are integrally connected and pivoted to the cover so as to be able to swing freely, when it is desired to operate the manual operation member with a small operating force, the manual operation member protruding outward from the cover may be The disadvantage is that the operating lever must be long;
When it is desired to shorten the operating lever, there is a disadvantage that the operating force becomes large. However, in the present invention, a swinging member for operating the air pump is provided in addition to the swinging manual operating member that is pivotally supported on the cover. Since the swinging member is configured to swing in conjunction with the swinging operation of the manual operating member, it is possible to reduce the operating force even if the operating lever is made relatively short.

〔Effect of the invention〕

Due to the effect of (a) above, the manual operation member can be operated in a stable posture in which a large overturning moment is unlikely to occur when the manual operation member is operated, and moreover, with small movements.

Due to the effect of (b) above, the manual operation member can be operated accurately without increasing the size of the entire liquid storage container, and while monitoring both the manual operation member and a container such as a tip.

Due to the effect of (c) above, even if the cover of the liquid injection tube is small, the manual operation member can be attached.

Due to the effect (d) above, it can be easily operated with a small operating force.

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.
