Total Claims: 4
Claim 1
Independent Claim
161 words
A thin-walled plastic closure lid for a container, said plastic characterized by the property of exhibiting stress patterns in areas proximate to cuts in said lid in response to the formation of said cuts, said stress pattern causing the weakening of said plastic in the area thereof, said lid having a frangible portion for selectively providing a straw receiving aperture therein, said fragible portion comprising: a first continuous score line on a surface of said lid extending along a first path; a second score line on said surface extending along a second path which intersects said first path at a predetermined point, said second score line stopping short of said predetermined point on both sides thereof on said second path; said score lines being of sufficient depth to facilitate puncturing of said lid in the area of said score lines to form a straw receiving aperture in said lid; said frangible portion being air tight and leak proof prior to puncturing.
Claim 2
Dependent Claim
161 words
A thin-walled plastic closure lid for a container, said plastic characterized by the property of exhibiting stress patterns in areas proximate to cuts in said lid in response to the formation of said cuts, said stress pattern causing the weakening of said plastic in the area thereof, said lid having a frangible portion for selectively providing a straw receiving aperture therein, said fragible portion comprising: a first continuous score line on a surface of said lid extending along a first path; a second score line on said surface extending along a second path which intersects said first path at a predetermined point, said second score line stopping short of said predetermined point on both sides thereof on said second path; said score lines being of sufficient depth to facilitate puncturing of said lid in the area of said score lines to form a straw receiving aperture in said lid; said frangible portion being air tight and leak proof prior to puncturing.
Claim 3
Dependent Claim
129 words
A thin-walled plastic closure lid for a container, said plastic characterized by the property of exhibiting stress patterns in areas proximate to cuts in said lid in response to the formation of said cuts, said stress pattern causing the weakening of said plastic in the area thereof, said lid having a frangible portion for selectively providing a straw receiving aperture therein, said frangible portion comprising: a plurality of cuts disposed along two paths which intersect at a predetermined point, said cuts stopping short of said predetermined point defining a diamond-shaped area which is weakened by the stress pattern of said cuts, thereby facilitating the puncturing of said lid in the diamond-shaped area to form an aperture in said lid; said frangible portion being substantially leak proof prior to puncturing.
Claim 4
Dependent Claim
129 words
A thin-walled plastic closure lid for a container, said plastic characterized by the property of exhibiting stress patterns in areas proximate to cuts in said lid in response to the formation of said cuts, said stress pattern causing the weakening of said plastic in the area thereof, said lid having a frangible portion for selectively providing a straw receiving aperture therein, said frangible portion comprising: a plurality of cuts disposed along two paths which intersect at a predetermined point, said cuts stopping short of said predetermined point defining a diamond-shaped area which is weakened by the stress pattern of said cuts, thereby facilitating the puncturing of said lid in the diamond-shaped area to form an aperture in said lid; said frangible portion being substantially leak proof prior to puncturing.
