Abstract

Abstract A dispenser package (10) is provided for flowable substances, where the flowable product is contained within a flexible pouch adhered to a relatively stiff sheet (12) which is opened along a fault line or pattern (24) with one hand by folding the stiff ends toward one another into a "V" shape. The pouch is formed with a shallow duct or channel area (25) directly behind the fault line (24) connecting two laterally spaced pockets (20, 21) located on either side of the fault line (24) to eliminate squirting or "spitting" of the flowable product upon rupture of the fault line. The stiff sheet (12) also may contain one or more protrusions (26) displacing at least a portion of the fault line out of the plane thereof, the protrusions (26, 30) comprising substantially pyramidal shapes having either straight-lined or curved profiles.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 224 words
A dispenser package for a flowable substance, said package including a relatively stiff substantially flat sheet and a flexible sheet secured to one face of said relatively stiff substantially flat sheet, said flexible sheet forming an enclosed pouch adjacent said one face of said relatively stiff substantially flat sheet for containing a flowable substance, said relatively stiff substantially flat sheet having a fault pattern of predetermined length whereby, upon bending said relatively stiff substantially flat sheet into a "V" about an axis extending along said fault pattern so that the arms of said "V" encapture said enclosed pouch, said fault pattern ruptures to create at least one opening through which said flowable substance is dispensed, said enclosed pouch having a pair of enlarged product-containing pockets spaced laterally on either side of said fault pattern and a connecting wall extending between said pockets located directly behind said fault pattern, said connecting wall forming a shallow connecting channel area adjacent the back side of said relatively stiff substantially flat sheet, whereby, upon initial bending of said relatively stiff substantially flat sheet and prior to rupture of said fault pattern, said connecting wall is caused to flex into pressing engagement with the back side of said relatively stiff substantially flat sheet thereby to force flowable product out of said channel area and into each of said pockets.
Claim 2
Dependent Claim 224 words
A dispenser package for a flowable substance, said package including a relatively stiff substantially flat sheet and a flexible sheet secured to one face of said relatively stiff substantially flat sheet, said flexible sheet forming an enclosed pouch adjacent said one face of said relatively stiff substantially flat sheet for containing a flowable substance, said relatively stiff substantially flat sheet having a fault pattern of predetermined length whereby, upon bending said relatively stiff substantially flat sheet into a "V" about an axis extending along said fault pattern so that the arms of said "V" encapture said enclosed pouch, said fault pattern ruptures to create at least one opening through which said flowable substance is dispensed, said enclosed pouch having a pair of enlarged product-containing pockets spaced laterally on either side of said fault pattern and a connecting wall extending between said pockets located directly behind said fault pattern, said connecting wall forming a shallow connecting channel area adjacent the back side of said relatively stiff substantially flat sheet, whereby, upon initial bending of said relatively stiff substantially flat sheet and prior to rupture of said fault pattern, said connecting wall is caused to flex into pressing engagement with the back side of said relatively stiff substantially flat sheet thereby to force flowable product out of said channel area and into each of said pockets.
Claim 3
Dependent Claim 30 words
A dispenser package as claimed in Claim 1, wherein said connecting wall is substantially parallel to and closely spaced from the back side of said relatively stiff substantially flat sheet.
Claim 4
Dependent Claim 15 words
A dispenser package as claimed in Claim 1, wherein said connecting wall is arcuately shaped.
Claim 5
Dependent Claim 30 words
A dispensing package as claimed in Claim 3, wherein the apex of said arcuate connecting wall is closely spaced from the back side of said relatively stiff substantially flat sheet.
Claim 6
Dependent Claim 25 words
A dispensing package as claimed in any preceding Claim, wherein said connecting wall-extends along substantially the entire width of each of said laterally spaced pockets.
Claim 7
Dependent Claim 41 words
A dispensing package as claimed in any preceding Claim, wherein the width of said connecting wall forming said channel area is sufficient to prevent said laterally spaced pockets from engaging one another during bending until after rupture of said fault line.
Claim 8
Dependent Claim 31 words
A dispensing package as claimed in any preceding Claim, wherein the wall of each of said laterally spaced pockets adjoining said connecting wall slopes laterally away from said connecting channel area.
Claim 9
Dependent Claim 145 words
A dispensing package as claimed in any preceding Claim, including protrusion means displacing at least a portion of said fault pattern out of the plane of said relatively stiff substantially flat sheet in a direction away from said one face for substantially maximally increasing the stress in said relatively stiff substantially flat sheet at the dispaced portion of said fault pattern, whereby, upon said bending of said relatively stiff substantially flat sheet, said fault pattern initially ruptures at the locus of said protrusion means to create at least one opening through which said flowable substance is dispensed in a directed flow, said protrusion means having a configuration which is substantially symmetrical on either side of said fault pattern and on either side of an axis normal to said fault pattern and in which the point of greatest displacement is located substantially on said fault pattern.
Claim 10
Dependent Claim 21 words
A dispensing package as claimed in Claim 8, wherein said protrusion means has a peaked cross-sectional shape along said fault pattern.
Claim 11
Dependent Claim 38 words
A dispensing package as claimed in Claim 8, wherein said protrusion means comprises a substantially pyramidal configuration and said fault pattern is displaced from said relatively stiff flat sheet material across the apex of said substantially pyramidal configuration.
