A SELF-CLOSING DISPENSING DEVICE

摘要

The present invention relates to a device for dispensing and/or metering flowable substances, such as powders, liquids or pastes, wherein the device includes a rigid open channel or basin-shaped first main part (1, 21) which includes a channel-like dispensing opening (2, 22), and a basin- or chanel-like second main part (3, 23) which is comprised of a resilient material and which has a shape complementary to the first main part (1, 21), wherein the first main part and the second main part are intended to be joined together to form a closed dispensing container, and wherein the second main dispenser part (3, 23) includes a closure part (9, 29) which is complementary to the dispensing part of the first main part and which lies resiliently against the dispensing opening. The closure part is comprised of an end-wall (4, 24) which lies against the side walls of the channel-like dispensing part at two points (8, 8') located inwardly of the dispensing opening of the dispensing channel, and a closure wall (9, 29) which is formed integrally with the resilient end-wall (4, 24) and, in a non-assembled state, is located essentially in a plane with the end-wall and has a longitudinal extension which is greater than the depth of the dispensing channel so that, in an assembled state, the closure wall will lie resiliently against the dispensing channel (2, 22) at an angle thereto, wherein the end-wall (4, 24) has a material thickness which is greater than the material thickness of the remainder of the second main dispenser part (3, 23) so that the main part will be deformed elastically in the vicinity of the end-wall (4, 24), whereas the end-wall will be deformed to only a slight extent, wherewith pressure applied to the end-wall will cause the wall to pivot against a spring force that derives from the deformation of the second main part (3, 23), wherewith the closure part (9, 29) swings away from the dispensing channel (2, 22) of the first main part.
