Problems solved by technology

[0002] In the case of dropper bottles with metering pumps, it has been shown that operational difficulties with regard to pump actuation may occur, especially for elderly or disabled persons, if, for example, an equivalent amount of preferably liquid medicine is to be drawn from the bottle, e.g. With each metering stroke of the metering pump, the actuating device of the metering pump with a smaller actuating surface will not be able to be actuated due to, for example, disability or disease.

Embodiment Construction

[0019] In the drawings, a drop bottle 1 is shown as an application example, for example for metered delivery of liquid medicine (equivalent to a certain number of drops of medicine). In the figures, only the upper head region of the dropper bottle 1 is shown.

[0020] In the area of ​​the upper opening of the dropper bottle 1 there is a metering pump shown as a whole by the reference number 2 . With the aid of this metering pump, a certain amount of eg liquid medicine can be delivered from the dropper bottle 1 in each metering stroke without the user having to count the number of drops to be delivered. The metering pump 2 has a pump head 3 and a pump outlet 5 in the region of its pump neck 4, through which a certain amount of liquid delivered by each metering stroke of the metering pump 2 can be discharged, for example for later collection In a small spoon or other container. Several possibilities are possible for the configuration of the pump outlet 5, and the invention is ...

Abstract

A pump actuation device intended in particular for a manual metering pump, provided on a drop bottle, for example for metering a quantity of liquid medicine. The actuating means on the pump head has a pump actuating surface which is substantially larger than the pump base to facilitate and aid handling. The pump actuation means can be made as a separate add-on part connected to the pump head or the actuation means can be formed as a single piece with the pump head.

Description

technical field [0001] The present invention relates to a pump actuator for a container-mounted manual metering pump having a pump base such as that provided on a drop bottle, preferably for metering quantities of liquid medicines and lotions. Background technique [0002] In the case of dropper bottles with metering pumps, it has been shown that operational difficulties with regard to pump actuation may occur, especially for elderly or disabled persons, if, for example, an equivalent amount of preferably liquid medicine is to be drawn from the bottle, e.g. With each metering stroke of the metering pump to withdraw and administer the drug, the actuation means of the metering pump with the smaller actuation surface will not be able to be actuated due to, for example, disability or disease. On the other hand, however, it is also very important that the delivered quantity metered by the metering pump can be collected easily and that the metering pump can perform its intended fu...
