The device tosqueeze paste out of tubes, has a housing with a cylindrical recess, a lengthwise slot, and a tube key fitting in the recess, in which it, with the tube, is easily fitted and removed. The slot opening (3) is elastic, this being typically achieved by regulating the material thickness of the housing (1) adjacent to the slot so that the opening yields elastically at a predetermined pressure. There can be a support for wall mounting, so that the tube inserted in the housing hangs downwards, with its nozzle fixed to a holder plate. Either the housing or the plate slide on the support. |
