Description

DETAILED DESCRIPTION OF THE INVENTION The present invention includes an openable lid and a lower body, and
In the lower body, a liquid container in which a mouth portion having a diameter smaller than the maximum body diameter portion of the container body is continuously provided on the upper portion of the container body,
The present invention relates to a liquid storage container with an air pump, which is provided with an air pump for sending the liquid in the liquid container out of the case.

As a thermos bottle, which is an example of this type of liquid container, various kinds have been used (for example, Japanese Utility Model Publication No. 58-17560, Japanese Utility Model Publication No. Sho 58-17560).
No. 58-17559 and Japanese Utility Model Publication No. 51-47091 are known, and any of these publicly known ones is, for example, as shown in FIG. 18, an upper lid (B) of a liquid container (2). The operation tool (100) of the air pump (P) was provided on the side.

In such a conventional thermos, since the operation tool (100) of the air pump (P) is provided on the top lid (B) side of the top of the container, the power point position of the pump operation also becomes high, and as a result,
Not only is it difficult to operate the pump on a table or the like, but it also contributes to a decrease in stability during pump operation. Moreover, even if the upper lid (B) is allowed to be opened and closed with respect to the main body (A), the operation tool (10) can be operated when the upper lid (B) is closed.
0) and the pump body are surely interlocked, the required manufacturing precision and assembling precision of the upper body (B), the air pump (P), and the container (2) as well as the lower body (A) are high. However, it has a drawback that it requires a high level of skill and much labor for manufacturing and assembling.

Apart from the above-mentioned conventional technique, if it is considered only to provide the operation tool at the lower position of the liquid storage container, for example, in Japanese Utility Model Application Laid-Open No. 50-987.
As disclosed in Japanese Patent Laid-Open No. 5 (1994), there is a means of disposing an air pump below the bottom of the liquid container and providing an operation tool for pressing the pump from below near the bottom of the case. However, if the operating tool is simply provided at a low position, the operating tool must be placed at a position on the back side of the case, etc., avoiding the lower portion of the discharge port for the extraction liquid from the liquid container. It was difficult to operate while watching the level.

SUMMARY OF THE INVENTION The present invention has an object to improve the operability of an air pump operating tool by reducing the above-mentioned conventional drawbacks by reasonably improving the layout of the components without requiring the overall manufacturing and assembling accuracy.

A characteristic configuration of a liquid storage container with an air pump according to the present invention, which has been devised to achieve such an object, is provided with an openable and closable upper lid and a lower main body, and the maximum body diameter portion of the container main body is provided in the lower main body. A liquid container in which a mouth portion having a diameter smaller than that of the liquid container is continuously provided on the upper part of the container body, and an air pump for sending the liquid in the liquid container out of the case is provided, and a liquid injection pipe on the front surface side of the lower body. In an air pump-equipped liquid storage container configured to pour the liquid from a liquid injection port cover portion covering the liquid injection pipe provided on the front surface side of the lower body, the operation tool of the air pump is provided. It is provided and the operation tool is configured to be vertically operable.

The operation and effect of the above characteristic configuration are as follows.

That is, (a) since the air pump operation device is arranged not on the upper lid side but on the lower body side and on the upper side of the lower body on the front side, even if the liquid container is on the table, the pump is not pumped much. The power point position of the operation does not become high, and moreover, it is easy to easily perform the pump operation while visually observing the relative positional relationship between the discharge port on the front surface side of the container and the liquid injection target container.

(B) Although the operation tool is located on the upper front surface side, which is higher than the bottom of the lower body, it is operated not vertically but in the vertical direction. On the other hand, there is little risk of acting in the falling direction, and it is easy to operate the pump with good stability.

(C) Since the operating tool and the pump main body are always in a fixed positional relationship regardless of whether the upper lid is opened or closed, the required manufacturing accuracy and assembly accuracy of each constituent member can be low even if they are reliably interlocked. In addition, the manufacturing and assembling can be facilitated and the efficiency can be improved.

(D) Since the operating tool is provided by using the dead space of the liquid inlet cover that protrudes forward from the peripheral wall of the lower body, it is reasonably possible to place the operating tool very close to the liquid inlet that is the easiest to operate. Since the arrangement space of the liquid container in the lower body is not reduced by the installation of the operation tool, the liquid container can be further downsized.

Embodiments of the present invention will be described below with reference to the drawings.
