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 handle portion (6), in that the tube (5) is made of a rigid pressure-elastic material, and in that the diameter of the bore (10) of the 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 the tube (5), and, on the other hand, the diameter of the bore (10) of the tube (5) is so large that, therein, no capillary effect occurs which would enhance the penetration of the contents (8) therein.

A dispensing container for a liquid or paste-like substance, comprising: two superimposed sheets of foil material, interconnected by means of a liquid-tight heat-sealed connecting seam, peripherally enclosing between said sheets a filling space, the interior of said filling space containing a liquid or paste-like substance, said sheets being extended beyond said filling space to form a handle portion; a channel pre-formed between said superposed sheets extending outwardly from said filling space into said handle portion; a tube in said preformed channel, said tube being open at both ends, having its inner open end in fluid communication with said filling space forming an outflow opening for said filling space, said tube being heat-sealed at its periphery to said sheets in said channel in a liquid-tight manner to prevent outflow of said substance from said filling space through said channel outside said tube; at least a portion of said extended sheet portions being adapted to be easily separated in order to uncover the outer open end of said tube so as to allow dispensing of the contents of said filling space; said pre-formed channel extending a substantial distance beyond the outer open end of said tube end into said handle portion, said heat seal connecting said tube to said two sheets and said heat seal connecting said two sheets of foil material being located sufficiently remote from the outer open end of said tube such that the bore of said tube is not closed by melting; said tube being made of a rigid pressure-elastic heat sealable plastics material which is resistant to the pressures and temperatures used when connecting said tube to said sheets of foil material in said liquid-tight manner, said tube being then deformed only to a slightly unround shape; a tear line formed in said handle portion for gaining access to said tube to permit discharge of the contents of the container through said tube, said tear line being situated slightly beyond the outer open end of said tube and extending in a direction which passes through said portion of said preformed channel which extends beyond the outer open end of said tube; the diameter of the bore of said tube depending on the viscosity and the surface tension of the contents of the container in respect of the tube material being, on the one hand, so small that said contents in the closed condition of the container will be kept by the surface tension outside the bore of said tube, and, on the other hand, the diameter of said tube being so large that no capillary effect occurs which would enhance the penetration of the contents of the container therein, whereby the contents of the container will not penetrate into the tube so that during opening, the contents will not splash outwards.
