A B S T R A C T A dispensing container or a liquid or paste-like sub- stance, consisting of two sheets of foil material, the edges of which are interconnected by means of a liquid-tight con- necting seam, enclosing therebetween a filling space, the in- terior of said filling space communicating with a tube fixed in said connecting seam, said tube forming an outflow opening, said sheets being extended beyond the end of this tube to form a handle, and being interconnected there in a liquid-tight man- ner in order to close the dispensing opening of said tube, at least a portion of these extended sheet portions being adapted to be loosened in order to uncover the dispensing opening of said tube so as to allow to dispense the contents of said fil- ling space, which is characterised in that the connecting seam between the foil sheets (1) near said tube (5) is provided with a preformed channel portion (4) in which said tube (5) is fixed in a liquid-tight manner, said channel (4) being extended (4') beyond the extremity of said tube (5) and into the handle por- tion (6), in that said tube (5) is made of a rigid pressure- elastic material, and in that the diameter of the bore (10) of said tube (5), depending on the viscosity and the surface tension of the contents (8) in respect of the tube material is, on the one hand, so small that the contents (8) in the closed condition of the container will be kept by the surface tension outside the bore (10) of said tube (5), and, on the other hand, the diameter of the bore (10) of said tube (5) is so large that, therein, no capillary effect occurs which would enhance the penetration of the contents (8) therein.
