A first embodiment of a package including superimposed flexible opaque and transparent sides and a circumferential peripheral seal determining an interior sealed enclosure for storing a liquid material includes two contiguous depending seals separated by a preformed slot dividing the enclosure bilaterally into a storage reservoir and a dispensing channel in fluid communication. The dispensing channel includes a closed lower end contiguous to a notch in the peripheral seal. Tearing the package at the notch results in collaterally tearing open the channel lower end and a contiguous portion of the peripheral seal, thereby enabling removal of package contents. Use of a ruled scale imprinted on the opaque side proximate to the dispensing channel and viewing through the transparent side the disposition of material in the channel enable the selection of a measured quantity of material to be expelled from the channel. A second embodiment is identical to the first embodiment except that a continuous divider which is easily torn to define a slot replaces the vertical slot separating the reservoir and channel. A third embodiment is identical to the second embodiment except that a scored line adjacent to the channel lower end enables a flap, formed when the package is torn open, to be folded upwardly where it can be secured to the package, thereby sealing the channel to prevent material leakage.

[ What is claimed is:] [1.] A dispensing package comprising:a sealed enclosure determined by superimposed first and second flexible sides and a peripheral seal circumscribing the sides, the seal comprising a top edge, a bottom edge, and opposed first and second side edges;means for dividing the sealed enclosure into a storage reservoir and a dispensing channel, the dispensing channel including an open distal end portion in fluid communication with the storage reservoir via a confluence, and an opposed closed proximal end portion contiguous to a section of the bottom edge of the peripheral seal and to a section of the second side edge, said dividing means comprising contiguous first and second depending seals determined by a preformed longitudinal divider defining a slot and extending from the bottom edge of the peripheral seal, each depending seal comprising an upper portion and an opposed lower portion, the upper portions being proximate to the confluence, and the lower portions being contiguous to the bottom edge of the peripheral seal;tear-open means, responsive to force means, for tearing open said sections of the second side edge and bottom edge and the proximal end portion; andmeasuring means for predetermining a quantity of liquid material to be expelled from the dispensing channel.
