PCT No. PCT/SE81/00014 Sec. 371 Date Sep. 21, 1981 Sec. 102(e) Date Sep. 21, 1981 PCT Filed Jan. 23, 1981 PCT Pub. No. WO81/02094 PCT Pub. Date Aug. 6, 1981.A measuring device for dispensing preferably viscous liquids comprising a container (4) for the liquid with a main space (28) and below the main space, a smaller space (29) which is in communication with the main space through a passage (37) and opens out through another passage (30). The portion which constitutes the smaller space (29) and the two passages (37, 30) is compressible. A member (3) is adapted, under the influence of spring forces, in a first position to compress the second passage (30). The member can be moved, against the action of said spring forces, into a second position in which it compresses the first passage (37) while the second passage (30) is open, so that in a third position, in which the member compresses the smaller space (29) and still the first passage (37), the liquid squirts out through the second passage (30). The measuring device comprises a first portion (1) which is intended to be mounted fixed and a second portion (2) which is adapted to be able to be displaced towards and away from the first portion (1) , the container (4) being adapted to be fitted between the first and second portions. The member (3) is supported between the two portions in such a manner that when the second portion is uninfluenced the member is held in its first position and when the second portion (2) is moved towards the first portion (1), the member (3) assumes the second and the third position in turn. The second portion has the form of a hood over the container (4) which is of soft material in which the passages (37, 30) and the spaces (28, 29) are formed. |
