Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
176 words
A package comprising a. a container having a body portion terminating at its upper end in an inwardly directed flange defining a mouth for removing the contents therefrom, said flange having an annular bead extending upwardly therefrom adjacent said mouth, the top of said annular bead forming the highest point of said container and means on said container for retaining a closure. b. a membrane extending across said mouth and adhered to said annular bead to seal said container, said membrane having a peripheral portion extending outwardly from said annular bead and overlying said flange, said outwardly extending peripheral portion being in unsealed relation to said container, and c. a closure engaged to said container, said closure having a top panel, an annular skirt depending therefrom and a shoulder positioned at the juncture between said top panel and annular skirt, said shoulder being spaced downwardly from said top panel in a position to engage the upper end of said container outwardly from said annular bead to limit the downwardly movement of the closure on the container.
Claim 2
Dependent Claim
176 words
A package comprising a. a container having a body portion terminating at its upper end in an inwardly directed flange defining a mouth for removing the contents therefrom, said flange having an annular bead extending upwardly therefrom adjacent said mouth, the top of said annular bead forming the highest point of said container and means on said container for retaining a closure. b. a membrane extending across said mouth and adhered to said annular bead to seal said container, said membrane having a peripheral portion extending outwardly from said annular bead and overlying said flange, said outwardly extending peripheral portion being in unsealed relation to said container, and c. a closure engaged to said container, said closure having a top panel, an annular skirt depending therefrom and a shoulder positioned at the juncture between said top panel and annular skirt, said shoulder being spaced downwardly from said top panel in a position to engage the upper end of said container outwardly from said annular bead to limit the downwardly movement of the closure on the container.
Claim 3
Dependent Claim
175 words
A package comprising a. a container having a body portion, a neck portion extending upwardly therefrom, a flange extending inwardly and upwardly from the top of said neck defining an open mouth, the uppermost portion of said flange being an upwardly extending annular bead, b. a membrane member extending across said mouth and sealed to said annular bead, said membrane member having a tear tab capable of being grasped extending radially outwardly beyond said annular bead, and c. a closure engaged to said container, said closure having a top panel portion, a wall portion extending downwardly from the periphery of said top panel portion, a shoulder extending outwardly from said wall portion, an annular skirt extending downwardly from said shoulder, and means for retaining the closure on the container, said shoulder engageable with the top of said neck to limit the downward movement of the closure on the container, said top panel urging the membrane member against the annular bead while permitting the tear tab portion thereof to remain out of contact with said flange.
Claim 4
Dependent Claim
175 words
A package comprising a. a container having a body portion, a neck portion extending upwardly therefrom, a flange extending inwardly and upwardly from the top of said neck defining an open mouth, the uppermost portion of said flange being an upwardly extending annular bead, b. a membrane member extending across said mouth and sealed to said annular bead, said membrane member having a tear tab capable of being grasped extending radially outwardly beyond said annular bead, and c. a closure engaged to said container, said closure having a top panel portion, a wall portion extending downwardly from the periphery of said top panel portion, a shoulder extending outwardly from said wall portion, an annular skirt extending downwardly from said shoulder, and means for retaining the closure on the container, said shoulder engageable with the top of said neck to limit the downward movement of the closure on the container, said top panel urging the membrane member against the annular bead while permitting the tear tab portion thereof to remain out of contact with said flange.
Claim 5
Dependent Claim
20 words
The package as defined in claim 2 wherein said tear tab extends completely around the periphery of the annular bead.
Claim 6
Dependent Claim
28 words
The package as defined in claim 6 wherein said flange is disposed at an angle greater than 10* from horizontal when the container is in an upright position.
Claim 7
Dependent Claim
232 words
A package comprising a. a container formed of flexible material, said container having a body portion terminating at its upper end in a neck portion having means thereon for retaining a closure, a flange extending inwardly and upwardly from said neck, said flange having an annular bead extending upwardly therefrom Adjacent said mouth, the top of said annular bead forming the uppermost portion of said container. b. a membrane extending across said mouth and adhered to said annular bead to seal said container, said membrane having a peripheral portion extending outwardly from said annular bead, said outwardly extending portion being in unsealed relation to said container and of sufficient radial extent to permit grasping, and c. a closure engaged to said container, said closure having a top panel, an annular skirt depending therefrom, and means engageable with the retaining means of said container, the application of said closure to said container causing said membrane to first engage the annular bead of the flange and then to deflect said flange downwardly to a position at which said bead remains as the highest point of the container, said closure having a shoulder at the juncture between the top panel and the annular skirt, said shoulder being spaced downwardly from said top panel in a position to engage the top of said container neck to limit the downward movement of the closure on the container.
Claim 8
Dependent Claim
232 words
A package comprising a. a container formed of flexible material, said container having a body portion terminating at its upper end in a neck portion having means thereon for retaining a closure, a flange extending inwardly and upwardly from said neck, said flange having an annular bead extending upwardly therefrom Adjacent said mouth, the top of said annular bead forming the uppermost portion of said container. b. a membrane extending across said mouth and adhered to said annular bead to seal said container, said membrane having a peripheral portion extending outwardly from said annular bead, said outwardly extending portion being in unsealed relation to said container and of sufficient radial extent to permit grasping, and c. a closure engaged to said container, said closure having a top panel, an annular skirt depending therefrom, and means engageable with the retaining means of said container, the application of said closure to said container causing said membrane to first engage the annular bead of the flange and then to deflect said flange downwardly to a position at which said bead remains as the highest point of the container, said closure having a shoulder at the juncture between the top panel and the annular skirt, said shoulder being spaced downwardly from said top panel in a position to engage the top of said container neck to limit the downward movement of the closure on the container.
