1. In a squeezable plastic pouch-like article of manufacture defining a cavity for containing a dispensable fluid and having flexible sidewalls, a bottom, a pair of spaced-apart outwardly-extending deformable side-edge margins, and a deformable upper-edge margin which is unitary with the side-edge margins and which defines a fluid passageway means that is able to communicate with the fluid cavity, wherein deformation of the upper-edge margin in the vicinity of the inlet of the fluid passageway means tends to block fluid communication between the fluid passageway means and the fluid cavity, wherein the improvement comprises:

  • the fluid passageway means being defined by a minor portion of the surface area of the deformable upper-edge margin, wherein the fluid discharge means is of generally serpentine configuration and has a fluid discharge end;

    deformation-causing means defined by at least one of the outwardly-extending side-edge margins and spaced from the upper-edge margin by a distance that is effective for causing deformation to occur in the side-edge margin that is in the vicinity of the deformation-causing means, rather than in the vicinity of the generally serpentine fluid passageway means, upon application of a predetermined squeezing pressure to the cavity-contained fluid via the article sidewalls, for purposes of enabling fluid to be discharged from the fluid-discharge end of the fluid passageway means;

    whereby fluid communication between the generally serpentine fluid passageway means and the fluid cavity is maintained upon application of the predetermined squeezing pressure to the cavity-contained fluid via the article sidewalls.
