Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
160 words
A dispensing package for a flowable substance, said package having a relatively stiff flat side and a flexible arched side secured to one side of said stiff flat side and forming between said stiff flat side and said flexible arched side a pocket for containing a flowable substance, said relatively stiff flat side having a cut pattern so as to form at least one tongue and one opening when said relatively stiff flat side is bent into a V about an axis through the base of said tongue and in a direction about said axis toward said pocket so that said flexible arched side and said flowable substance in said pocket are between the arms of said V, said arms of said V and said flexible side therebetween cooperating, as said arms are forced toward each other, and applying pressure on said flowable substance in said pocket and forcing said flowable substance to flow from said pocket through said opening.
Claim 2
Dependent Claim
160 words
A dispensing package for a flowable substance, said package having a relatively stiff flat side and a flexible arched side secured to one side of said stiff flat side and forming between said stiff flat side and said flexible arched side a pocket for containing a flowable substance, said relatively stiff flat side having a cut pattern so as to form at least one tongue and one opening when said relatively stiff flat side is bent into a V about an axis through the base of said tongue and in a direction about said axis toward said pocket so that said flexible arched side and said flowable substance in said pocket are between the arms of said V, said arms of said V and said flexible side therebetween cooperating, as said arms are forced toward each other, and applying pressure on said flowable substance in said pocket and forcing said flowable substance to flow from said pocket through said opening.
Claim 3
Dependent Claim
29 words
A package, as recited in claim 1, in which said cut pattern is an interrupted series of cuts forming a series of tongues extending across said stiff flat side.
Claim 4
Dependent Claim
