THIN-WALLED DOSING DEVICE HAVING AN INTEGRALLY MOULDED TRIGGER AND SPRING, AND METHOD FOR ASSEMBLING SAME

摘要

The invention relates to a device for dosed dispensing of a liquid from a container, comprising a housing (3) manufactured from plastic which can be connected to the container, a pump accommodated therein which can be operated by a trigger (8), and means (14) for resetting the trigger to a starting position. The housing takes a thin-walled form, for instance of polypropylene with a wall thickness of less than 1 mm, and has a number of stiffening ribs (17) extending inward from its side walls, while the pump can have a number of protruding supports engaging on the side walls of the housing. The trigger and the resetting means of the dosing device can be manufactured from a relatively more rigid type of plastic than the housing, for instance from a stiffer variant of the plastic used in the housing and/or the pump, and can be manufactured integrally. The invention also relates to a method for assembling such a dosing device.
