Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 328 words
In a dispensing squeeze package for liquid contents wherein said package is formed from superposed sheets of flexible liquid-impermeable material connected in liquid-tight relation completely around the periphery thereof and defining therebetween (1) a contents-receiving pouch, and (2) a discharge spout communicating at an inlet end thereof with said pouch and terminating at an outlet end thereof within the periphery of said peripherally connected sheets, said sheets being tearable in proximity to said spout outlet end to disrupt said connected sheets near said spout outlet end to open the spout thereby to permit squeeze-dispensing pressure on said sheets at said pouch therein to force said contents from within said pouch through said spout to dispense the same, the improvement therein comprising: said spout defining a flow channel formed between and defined completely by said superposed flexible sheets, with said sheets being connected together along the length of the channel on either side thereof between its said inlet and outlet ends, said flow channel having a serpentine configuration including a first flow channel portion extending from said inlet end in a first direction away from said contents pouch, a seocnd flow channel portion having a curvilinear connection to said first flow channel portion and extending therefrom in a second direction and including a reversely directed component thereof directed toward said contents pouch, a third flow channel portion having a curvilinear correction to said second flow channel portion and extending therefrom in a third direction to said outlet end and including a component thereof reversely directed with respect to said second flow channel component and extending away from said contents pouch in generally said first direction, and, tear means intersecting said spout at said outlet end thereof, thereby to provide a substantially flat squeeze package, the spout configuration of which provides manual squeeze-controlled flow from said contents pouch with dripless cessation of flow from said spout upon relaxation of squeeze pressure when said spout is opened at its outlet end.
Claim 2
Dependent Claim 328 words
In a dispensing squeeze package for liquid contents wherein said package is formed from superposed sheets of flexible liquid-impermeable material connected in liquid-tight relation completely around the periphery thereof and defining therebetween (1) a contents-receiving pouch, and (2) a discharge spout communicating at an inlet end thereof with said pouch and terminating at an outlet end thereof within the periphery of said peripherally connected sheets, said sheets being tearable in proximity to said spout outlet end to disrupt said connected sheets near said spout outlet end to open the spout thereby to permit squeeze-dispensing pressure on said sheets at said pouch therein to force said contents from within said pouch through said spout to dispense the same, the improvement therein comprising: said spout defining a flow channel formed between and defined completely by said superposed flexible sheets, with said sheets being connected together along the length of the channel on either side thereof between its said inlet and outlet ends, said flow channel having a serpentine configuration including a first flow channel portion extending from said inlet end in a first direction away from said contents pouch, a seocnd flow channel portion having a curvilinear connection to said first flow channel portion and extending therefrom in a second direction and including a reversely directed component thereof directed toward said contents pouch, a third flow channel portion having a curvilinear correction to said second flow channel portion and extending therefrom in a third direction to said outlet end and including a component thereof reversely directed with respect to said second flow channel component and extending away from said contents pouch in generally said first direction, and, tear means intersecting said spout at said outlet end thereof, thereby to provide a substantially flat squeeze package, the spout configuration of which provides manual squeeze-controlled flow from said contents pouch with dripless cessation of flow from said spout upon relaxation of squeeze pressure when said spout is opened at its outlet end.
Claim 3
Dependent Claim 24 words
The improved dispensing package of claim 1 wherein said spout is tapered to define said inlet end of greater width than said outlet end.
Claim 4
Dependent Claim 19 words
The improved dispensing package of claim 1 wherein said sheets are formed at least in part from polymeric material.
Claim 5
Dependent Claim 26 words
The improved dispensing packages of claim 3 wherein said sheets are bonded in face-to-face relation throughout their superposed surfaces peripherally of said pouch and said spout.
Claim 6
Dependent Claim 15 words
The improved dispensing package of claim 4 wherein said sheets are bonded by heat seals.
Claim 7
Dependent Claim 24 words
The improved dispensing package of claim 1 wherein said tear means extends across said spout third flow channel portion near the outlet end thereof.
Claim 8
Dependent Claim 44 words
The improved dispensing package of claim 6 wherein said package is substantially rectangular in outline, and said spout outlet end is disposed adjacent one corner of said package, with said tear means extending between adjacent package sides and across said spout outlet end therebetween.
Claim 9
Dependent Claim 15 words
The improved dispensing package of claim 3 wherein said sheets include biaxially oriented polymeric material.
