ABSTRACT:
The invention concerns a device on a rigid or deformable container with a container neck, for the dosage and delivery of a variable, measurable quantity of a medium that can flow, trickle or be poured, according to the description of patent claim
1
.
Containers on which such devices are installed are employed with the container neck pointing downward, in which case manual pressure on the device enables the medium in the container to flow into a metering chamber, until a desired quantity is reached. If the manual pressure on the device, in the direction of the bottle, is released, the flow is stopped.
Known dosing and metering devices are known in the most diverse execution variants. Their configuration is thereby dependent essentially upon the type of container on which they are installed. For example, such devices are installed on bottles for alcoholic beverages and are only suitable for dosing very specific, always identical quantities. Other devices, for example, those for dentifrice mouthwashes, require deformable containers in order to discharge the liquid into a metering chamber, their return flow being made impossible by a type of siphon. If not all the dosed quantity is used, the residual quantity will remain in the metering chamber, which is not tight enough to keep the residual quantity from drying out. This leads not only to unhygienic conditions, but often likewise impairs the operation of the device, or makes it impossible.
There are many known dosing devices which are not tight or not precise. Finally, however, dosing and metering devices are also known that belong rather to the realm of the laboratory and that, if only by reason of cost, are not usable in the consumer field of interest here,
It is consequently the task of the present invention to create a simple dosing and metering device, in particular one that can be produced simply using plastics technology, in which the above-indicated disadvantages are avoided.
