  • Patent number: 4921137
    Abstract: A dispensing container for a liquid or paste-like substance, consisting of two sheets of foil material, the edges of which are interconnected by means of a liquid-tight connecting seam, enclosing therebetween a filling space, the interior of the filling space communicating with a tube fixed in the connecting seam, the tube forming an outflow opening, the sheets being extended beyond the end of this tube to form a handle, and being interconnected there in a liquid-tight manner in order to close the dispensing opening of the tube, at least a portion of these extended sheet portions being adapted to be loosened in order to uncover the dispensing opening of the tube so as to allow to dispense the contents of the filling space, which is characterized in that the connecting seam between the foil sheets (1) near the tube (5) is provided with a preformed channel portion (4) in which the tube (5) is fixed in a liquid-tight manner, the channel (4) being extended (4') beyond the extremity of the tube (5) and into the ha

  • Patent number: 4863036
    Abstract: A container for a small quantity of milk, cream or the like, comprising a tub-shaped filling cavity (1) with a flat circumferential stiff rim (4) and a cover sheet (5) thereto by means of a sealing seam, said flat rim and cover sheet at one side being extended beyond the connecting seam (6), for forming a pulling tab (5') allowing said sheet to be pulled away for forming a dispensing opening. In the extended rim portion (4') of the stiff rim (4) a channel (7) communicating with the filling cavity (1) is formed, extending slightly beyond the connecting seam (6) and transversely to the outer boundary (8) of said seam (6), said channel (7), beyond the connecting seam (6), being surrounded by an additional sealing seam (9) which is weaker than the connecting seam portion (6') extending transversely to said channel (7), so that said pulling tab (5') can be pulled away up to said connecting seam (6' ), for uncovering a dispensing opening (7') with a fixed small dimension of said channel (7).

  • Patent number: 4534353
    Abstract: An accessory for counteracting the consequences of vesical incontinency with males, comprising an annular tensioning means (8, 9) adapted to be tensioned around the penis (1) of the user, and further comprising a pressure element (7) with a rounded and relatively stiff pressing surface (10) having a curvature which is substantially adpated to the shape of the swelling bodies (3) of the penis (1) so as to pinch the urethra (5) elastically against said bodies (3) which are retained by the tensioning means (8, 9), said pressure element (7) being, in particular, a strip of a substantially rigid material having, more in particular, lateral portions (16, 17) which are substantially adapted to the shape of said bodies (3).

  • Patent number: 4428907
    Abstract: The invention provides a detector for detecting air components, e.g. contaminations, and in particular noxious or poisonous contaminations, which device comprises a housing in which an air pervious carrier containing a first reagent is arranged, this detector being adapted to draw air to be tested through said carrier so as to expose this reagent to the air, this reagent being influenced by the components to be detected, which carrier is to be contacted with a second reagent which, together with the first one, can bring about a color reaction depending on the fact whether the first reagent has been influenced or not.
