Abstract
Abstract A container and a hermetically sealable and removable cover therefor each formed of locally deformable thermoplastic material and each having depending skirts. The container skirt forms part of a rim flange with a semi-circular upper portion and the skirt is of decreasing thickness viewed downwardly. The closure skirt forms an outer wall of a downwardly open groove for receiving the container rim flange and which has a complementary semi-circular top groove wall. The cover skirt increases gradually in thickness viewed downwardly and serves to flex the container skirt inwardly on engagement of the cover whereby to provide a resilient gripping engagement of the cover and container.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
174 words
A container and a hermetically sealable and removable cover therefor, said container and cover being formed of a resilient and locally deformable thermoplastic material and said container having a bottom and a generally Vertical side wall and an upwardly open mouth, said side wall having adjacent said mouth and outwardly disposed therefrom an integral peripheral rim flange with a generally horizontally outwardly projecting portion and a depending skirt spaced outwardly from and flexible inwardly toward said side wall, said skirt having a generally vertical outer peripheral surface, said cover having a peripheral downwardly open groove with an outer wall thereof defined by an inner surface of a depending peripheral skirt and inclined inwardly and downwardly from the vertical, said skirt being of a somewhat greater thickness than said container skirt, said container rim flange being fully seated in said cover groove forming a frictional telescopic, and hermetical engagement with said container skirt, and said container skirt being flexed inwardly be said cover skirt thereby providing a resilient gripping engagement between said cover and flange.
Claim 2
Dependent Claim
174 words
A container and a hermetically sealable and removable cover therefor, said container and cover being formed of a resilient and locally deformable thermoplastic material and said container having a bottom and a generally Vertical side wall and an upwardly open mouth, said side wall having adjacent said mouth and outwardly disposed therefrom an integral peripheral rim flange with a generally horizontally outwardly projecting portion and a depending skirt spaced outwardly from and flexible inwardly toward said side wall, said skirt having a generally vertical outer peripheral surface, said cover having a peripheral downwardly open groove with an outer wall thereof defined by an inner surface of a depending peripheral skirt and inclined inwardly and downwardly from the vertical, said skirt being of a somewhat greater thickness than said container skirt, said container rim flange being fully seated in said cover groove forming a frictional telescopic, and hermetical engagement with said container skirt, and said container skirt being flexed inwardly be said cover skirt thereby providing a resilient gripping engagement between said cover and flange.
Claim 3
Dependent Claim
29 words
A container and hermetically sealable and removable cover therefor as set forth in claim 1 wherein said container skirt is of gradually decreasing thickness viewed from top to bottom.
Claim 4
Dependent Claim
48 words
A container and hermetically sealable and removable cover therefor as set forth in claim 1 wherein said cover has an integral outwardly projecting peripheral rim at a lower end portion thereof, said rim providing for ease in manual manipulation during engagement and disengagement of said container and cover.
Claim 5
Dependent Claim
52 words
A container and hermetically sealable and removable cover therefor as set forth in claim 1 wherein said cover groove has an arcuate top wall and wherein said rim flange has an arcuate upper surface on said generally horizontal portion which is complementary to said arcuate top wall for hermetic sealing engagement therebetween.
Claim 6
Dependent Claim
60 words
A container and hermetically sealable and removable cover therefor as set forth in claim 4 wherein said arcuate groove top wall and said arcuate upper surface on said rim flange are each partially circular in cross section with the aforesaid downwardly and inwardly inclined outer groove wall lying in a plane depending from and tangent to said arcuate top wall.
Claim 7
Dependent Claim
36 words
A container and hermetically sealable and removable cover therefor as set forth in claim 5 wherein said arcuate groove top wall and said arcuate upper surface on said rim flange are each semi-circular in cross section.
Claim 8
Dependent Claim
41 words
A container and hermetically sealable and removable cover therefor as set forth in claim 6 wherein an integral upright peripheral portion is formed on a generally flat horizontal body portion of said cover to provide said inner wall of said groove.
Claim 9
Dependent Claim
44 words
A container and hermetically sealable and removable cover therefor as set forth in claim 7 wherein said container skirt is of gradually decreasing thickness viewed from top to bottom, and wherein said cover skirt is of gradually increasing thickness viewed from top to bottom.
Claim 10
Dependent Claim
45 words
A container and hermetically sealable and removable cover therefor as set forth in claim 8 wherein said cover skirt is substantially longer than said container skirt and has a rounded inner and lower edge portion for ease in engagement and disengagement with said container skirt.
Claim 11
Dependent Claim
48 words
A container and hermetically sealable and removable cover therefor as set forth in claim 9 wherein said cover has an integral outwardly projecting peripheral rim at a lower end portion thereof, said rim providing for ease in manual manipulation during engagement and disengagement of said container and cover.
