Abstract
Abstract Envelope of supple material, such as plastic, having a sealed chamber confines the substance. The chamber is formed with a narrowing portion, and the envelope has a cut in one side adjacent the narrowing portion to insure a tearing open of the envelope across the narrowing portion. Thus, a restricted pouring nozzle is provided. The envelope has a stiffener therewithin to make it handy to hold during pouring. Also, the stiffener cooperates with the cut to facilitate a tearing of the envelope across a predetermined line.

Means providing a dosage of oral hygienic substance, comprising: a pair of leaves of supple, light-transmissive material, said leaves being superimposed, one upon the other thereof, and being sealed together by means of a first, continuous seal fully about the periphery of said leaves to define an envelope; said leaves being further sealed together by a second seal which, cooperative with said first seal, forms two separate chambers within said envelope, and defines each of said chambers with a first, narrowed-off portion and a second, widened portion; wherein said first, narrowed-off portion of one of said chambers is juxtaposed with said second, widened portion of the other of said chambers, and vice versa; a dosage of oral hygienic substance confined within one of said chambers; and a substantially triangular-shaped stiffener confined within the other of said chambers, said stiffener occupying substantially all of said other chamber; said leaves having a common cut formed in edges thereof adjacent to both said first seal and said second, widened portion of said other, stiffener-confining chamber; said stiffener having a linearly disposed line of perforations formed therein, one end of said line being in immediate, aligned adjacency to said common cut; said cut and said perforations being cooperative to facilitate a tearing open of said envelope, and a resultant opening of said first and second portions, respectively, of said one and other chambers; said stiffener, cooperative with said first and second portions of said other chamber, providing for an efficient handling of said envelope during a pouring of said substance from said one chamber via said first portion of said one chamber; and wherein said first portion of said one chamber, on being torn open, defines a restricted pouring nozzle more readily to control evacuation of said substance.

Means providing a dosage of oral hygienic substance, comprising: a pair of leaves of supple, light-transmissive material, said leaves being superimposed, one upon the other thereof, and being sealed together by means of a first, continuous seal fully about the periphery of said leaves to define an envelope; said leaves being further sealed together by a second seal which, cooperative with said first seal, forms two separate chambers within said envelope, and defines each of said chambers with a first, narrowed-off portion and a second, widened portion; wherein said first, narrowed-off portion of one of said chambers is juxtaposed with said second, widened portion of the other of said chambers, and vice versa; a dosage of oral hygienic substance confined within one of said chambers; and a substantially triangular-shaped stiffener confined within the other of said chambers, said stiffener occupying substantially all of said other chamber; said leaves having a common cut formed in edges thereof adjacent to both said first seal and said second, widened portion of said other, stiffener-confining chamber; said stiffener having a linearly disposed line of perforations formed therein, one end of said line being in immediate, aligned adjacency to said common cut; said cut and said perforations being cooperative to facilitate a tearing open of said envelope, and a resultant opening of said first and second portions, respectively, of said one and other chambers; said stiffener, cooperative with said first and second portions of said other chamber, providing for an efficient handling of said envelope during a pouring of said substance from said one chamber via said first portion of said one chamber; and wherein said first portion of said one chamber, on being torn open, defines a restricted pouring nozzle more readily to control evacuation of said substance.
