Abstract
A device for dispensing a dosage material has a container with an outlet spout and a metering element adjoining the outlet spout. The metering element has an inlet opening on a side facing the container and an outlet opening on a side that faces away from the container. A wall of the metering element extends between the openings. A film material can be inserted into the device which passes at least through the inlet opening and the slot-shaped outlet opening and covers the inside of the wall. The device also has a feature that stretches a portion of a tube section of the film material. This stretching device includes at least two locations for fastening the portion to be stretched, the two locations being arranged on a stretch line that is at an angle to the lengthwise direction of the tube section.
Claims18
A device for dispensing a material in dosages, comprising:
- a container for the dosage material;
- an outlet spout of the container;
- and
- a metering element, adjoining the outlet spout, the metering element comprising:
- an inlet opening on a side that faces towards the container;
- an outlet opening on a side that faces away from the container, the outlet opening being slot-shaped when in a closed condition;
- and
- a wall with an inside and an outside, extending between the inlet and outlet openings
- a film material which is inserted into the metering element to reach at least through the inlet opening and the outlet opening while covering the inside of the wall, the inserted film material formed into a tube section from at least the inlet opening through the outlet opening, the tube section extending into a space below the outlet opening;
- and
- a stretching device that stretches a cross-sectional perimeter of a portion of the tube section, the cross-sectional perimeter defined by a plane arranged at an angle to a lengthwise direction of the tube section, the stretching device comprising:
- a first location for fastening the portion;
- and
- a second location for fastening the portion,
- the respective fastening locations positioned on the stretch line, with at least one of the fastening locations being linearly displaceable therealongalong the stretch line, the fastening locations dividing the cross-sectional perimeter into two perimeter segments of essentially equal length.
