Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a liquid pumping type liquid container that allows display of the remaining amount of liquid contained therein.

Conventionally, in order to determine the remaining amount of liquid in this type of liquid container, a gravimetric method has been adopted in which the liquid container is placed on a weighing platform and the amount of water used is subtracted from the total weight. Since a spring is interposed between the liquid container and the weighing stand, which are constructed separately, there is a problem in that the liquid container swings on the weighing stand, giving the user a sense of anxiety. Furthermore, as disclosed in Japanese Utility Model Application Publication No. 52-149454, an inner container and a shoulder member having a spout are integrally connected to form a unit, and the unit can be moved vertically relative to a main body having a handle. Some systems have made it possible to visually check the amount of vertical displacement of this unit from the outside, but in this case, the problem is that the unit swings during injection, etc., giving the user a sense of anxiety. In addition, when this known technique is applied to a liquid pumping type liquid container, there is a problem in that the inner container etc. swing when the liquid pumping device is operated, making it difficult to perform the liquid filling operation.

The present invention has been made in view of the above points, and
The object of this invention is to enable reliable display of the remaining amount of liquid content without impairing operability during liquid injection.

In order to achieve the above object, the present invention provides a liquid pumping type liquid container configured such that a liquid pumping device pumps up and dispenses liquid stored in an inner container disposed within a container main body. A spring is interposed between the bottom of the inner container and the inner bottom of the container body, and a seal is provided between the upper opening of the inner container and the liquid supply port of the shoulder member constituting the upper part of the container main body. At the same time, a gasket that expands and contracts according to the vertical displacement of the inner container is provided to support the inner container within the container body so as to be able to move up and down. The structure is characterized by a display section that displays the amount of displacement so that it can be visually recognized from the outside.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

As shown in FIG. 1, the liquid pumping type liquid container of this embodiment includes a container body 1 configured to store liquid therein, and a lid 2 pivotably attached to the upper part of the container body 1 so as to be openable and closable. It is composed of.

The container body 1 is composed of a cylindrical outer case 4 made of sheet metal, and a shoulder member 5 and a bottom member 6 made of synthetic resin that cover the upper and lower openings of the outer case 4.

Inside the container body 1, an inner container 3 made of a vacuum double bottle is elastically supported by a spring 7 interposed between its bottom surface and a bottom member 6, and is movable up and down. It is located in The outer periphery of the inner container 3 is covered with a protective cover 8 to protect it from damage and accidents.

The protective cover 8 includes a support portion 8a that supports the inner container 3 and a lid portion 8b that is screwed onto the top of the support portion 8a.
In the center of the lid part 8b, there is an upper opening 3a of the inner container 3 and a liquid supply port 20 of the shoulder member 5.
An opening 9 having approximately the same diameter is formed.

A bellows-shaped elastic gasket 10 having one end fixed to the lower surface of the shoulder member 5 is attached to the edge of the opening 9. The packing 10 is attached to the inner container 3
It expands and contracts according to the vertical change of the inner container 3, and acts to seal between the upper opening 3a of the inner container 3 and the liquid supply port 20.

In addition, in this embodiment, as shown in FIG. 2, a window 12 through which the inside can be seen is formed at a suitable location in the outer case 4, and on the side of the window 12 there are symbols "0", "50", "100", etc. ” is provided as a display section 11 that displays the amount of vertical displacement of the inner container 3. That is, by observing from the outside whether the mark 14 provided on the side surface of the protective cover 8 matches the remaining amount scale 13, the remaining amount of the liquid in the inner container 3 can be determined. .

Further, inside the lid body 2, an air pump 15 is provided which acts as a liquid pumping device for pumping up the liquid stored in the inner container 3.
An operating member 16 is provided for pressing and driving the air pump 15, and pressurized air is fed into the inner container 3 by the pressure driving of the air pump 15, and the content is controlled by the pressure of the pressurized air. The liquid inside the container 3 can be led out to the outside through a liquid pumping pipe 18 and a liquid pouring pipe 19 connected to an inner stopper 17 that is tightly fitted into the liquid supply port 20.

Next, the operation of the illustrated liquid pumping type liquid container will be explained.

The inner container 3 of this liquid container is in the state shown by the solid line in FIG. 1 when the amount of the content liquid is "0",
The mark 14 on the protective cover 8 coincides with the "0" position on the remaining amount scale 13, as shown in FIG.

When the lid 2 of this liquid container is opened, the inner stopper 17 is removed together with the liquid pumping tube 18 and the liquid pouring tube 19, and liquid is supplied into the inner container 3, the inner container 3 descends against the urging force of the spring 7, and is displaced to the position shown by the dotted line in FIG. 1 when the liquid is full. At this time, the mark 14 on the protective cover 8
corresponds to the "100" position on the remaining amount scale 13, indicating a full liquid state.

Thereafter, pressurized air is blown into the inner container 3 from the air pump 15 by pressing the operating member 16, and the pressurized air moves the liquid in the inner container 3 to the liquid pumping tube 18 and the liquid spouting tube 19. When the remaining amount in the inner container 3 decreases as a result of repeating the operation of drawing it out to the outside through the inner container 3, the inner container 3 is raised by the biasing force of the spring 7, and the remaining amount is aligned with the mark 14 of the protective cover 8. The remaining amount can be determined by the point that matches the scale 13. For this purpose, it is necessary to employ a spring in which the weight of the liquid stored in the inner container 3 and the biasing force of the spring 7 are proportional.

In the above embodiment, a manual air pump is used as the liquid pumping device 15, but it goes without saying that an electric air pump or an electric axial flow pump may be used instead. be.

Next, the effects of the liquid pumping type liquid container of the present invention will be described.

According to the present invention, the spring 7 is interposed between the bottom of the inner container 3 and the inner bottom of the container body 1, and the shoulder member 5 constituting the upper opening 3a of the inner container 3 and the upper part of the container body 1 is According to the present invention, a packing 10 is interposed between the inner container 3 and the liquid supply port 20 to seal the space between the two and expand and contract according to the vertical displacement of the inner container 3. A display section 11 is provided on the outer peripheral surface of the container body 1 to display the amount of vertical displacement of the inner container 3 in a visible manner from the outside. The remaining amount of the liquid content can be displayed by vertical displacement, which not only makes it possible to accurately display the remaining amount, which is the original function, but also improves stability when operating the liquid pumping device 15 and when carrying the liquid container. It has the excellent effect of being able to be secured.
