Abstract

A dosage-dispensing device, which can be used for dosage materials in the form of powders or pastes, includes a housing with at least one receptacle compartment formed inside the housing for the purpose of holding the dosage material. The dosage-dispensing device further includes at least one dispensing head that comprises an elastic material and has an outlet for the dosage material. In the non-stressed condition, i.e. when there is no mechanical force or pressure acting on it, the outlet is tightly closed against the outside. When a force or pressure is applied, the outlet opens up, with the aperture width being variable, dependent on the applied force. Furthermore, inside the receptacle compartment and/or the dispensing head, there is at least one mechanical actuator element arranged through which the outlet can be opened.

Dependent claims

A dosage dispensing device, for dosage materials in the form of powders or pastes, comprising:

a housing;
a receptacle compartment formed inside the housing adapted to hold dosage material;
a dispensing head, the dispensing head comprising an elastic material and including an outlet, the outlet closes tightly against the outside in the absence of mechanical force and opens to a variable aperture width when force is applied;
a mechanical actuator element capable of linear movement along the lengthwise axis of the housing, the mechanical actuator element is arranged in at least one of a receptacle compartment and a dispensing head;
the outlet opens when force generated by the mechanical actuator, substantially from the direction of the receptacle compartment, is directed toward the outlet;
and
a mechanical conveyor means arranged in at least one of the receptacle compartment and the dispensing head, the conveyor means operable to advance the dosage material towards the outlet.
