DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to a measuring device for dispensing preferably viscous liquids and comprising a container for the liquid having a main space and a smaller space which is below the main space and is in communication with the main space through a passage and opens through another passage. The part which constitutes the smaller space and the two passages is compressible. A member is adapted to compress the second passage under the influence of spring force, in a first position. Against the action of said spring force, the member can be brought into a second position in which it compresses the first passage while the second passage is open, so that in a third position, in which the member compresses the smaller space with continued compression of the first passage, the liquid squirts out through the second passage while at the same time the flowing back of the liquid through the first passage to the larger space is prevented.
BACKGROUND ART
Measuring devices of the kind indicated are often intended for portioning out washing agents such as soap solution for washing the hands and body. Such devices are often used in nursing. In this case it is important to meet high hygienic demands which indicates the use of throw-away containers and a portioning out device of a once-only character. As a result, said parts are replaced at uniform intervals, in time with the consumption of the washing agent, which reduces the need for maintenance and reduces the risk of the growth of bacteria. With devices used in nursing it is also important that the manipulation during the portioning out should be as simple as possible with the control member of such a construction that manipulation can take place with the elbow so that the control member does not need to be touched by the hand.
From the publication of the Swedish Patent Application No. 7603865-2, a two-chamber pack is known for dispensing liquids in determined doses. This pack comprises a relatively complicated valve construction and therefore, if it is made as a throw-away pack, the pack encumbers the product with a relatively high cost while it must require complicated tool equipment for its manufacture.
THE TECHNICAL PROBLEM
The object of the present invention is to provide a measuring device which is suitable for use in connection with a throw-away pack and which, through its simplicity, can involve a low price and which can be manufactured in a simple manner.
One problem, which is also to be solved by the present invention, is to provide a simple and practical manipulation possibility for the device.
THE SOLUTION
The solution, which is indicated by the invention consists in that the liquid container is formed like a soft bag which is provided with passages and chambers in such a manner that these parts form the liquid-carrying part of the measuring member which is completed by other members which do not come into contact with the liquid. Furthermore, in the invention, a hood is designed as a control member.
ADVANTAGES
As a result of the fact that the bag-shaped throw-away container for liquid is fashioned with the liquid-carrying measuring member, this is also replaced as soon as the liquid is used up, as a result of which a satisfactory hygiene is maintained in comparison with devices in which the measuring mechanism is never replaced during the life of the device, while at the same time a very simple construction is obtained through the division of the member into liquid-carrying and non-liquid-carrying parts. As a result of the fact that the hood is used as an external control member no separate control member need to be provided but an integration of covering and control member is obtained. At the same time, the member becomes easily manipulated as a result of a large surface in comparison with conventional buttons, levers and the like.
