Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
147 words
A container and removable interlocked closure of circular form; the container being comprised of a base and an upstanding perimeter wall defining an open topped fluid tight vessel, a circumferential and outwardly disposed peripheral bead in a normal plane at the open top of the container, the closure being comprised of a wall engaged with the bead and a rim circumferentially coextensive with and conforming to said bead and with a ridge continuously underlying the said bead to interlock therewith, seal means disposed between the closure wall and the bead, and a circumferentially continuous conical skirt depending divergently from the said ridge and presenting a manually engageable edge remote from the rim for outward upward deflection deforming the rim and causing it to revolve the ridge outward from the bead in opposite circumferential directions from any point of deflection to thereby release the closure from the container.
Claim 2
Dependent Claim
147 words
A container and removable interlocked closure of circular form; the container being comprised of a base and an upstanding perimeter wall defining an open topped fluid tight vessel, a circumferential and outwardly disposed peripheral bead in a normal plane at the open top of the container, the closure being comprised of a wall engaged with the bead and a rim circumferentially coextensive with and conforming to said bead and with a ridge continuously underlying the said bead to interlock therewith, seal means disposed between the closure wall and the bead, and a circumferentially continuous conical skirt depending divergently from the said ridge and presenting a manually engageable edge remote from the rim for outward upward deflection deforming the rim and causing it to revolve the ridge outward from the bead in opposite circumferential directions from any point of deflection to thereby release the closure from the container.
Claim 3
Dependent Claim
61 words
The container and reusable interlocked closure as set forth in claim 1, wherein the outward peripheral bead of the container is a flattened roll adjacent the perimeter wall of the containeer and having a surface tangent to the opposed underside of the closure wall, and wherein the rim and ridge formed on the cover conform to the said flattened roll configuration.
Claim 4
Dependent Claim
52 words
The container and reusable interlocked closure as set forth in claim 1 wherein the skirt is substantially rigid with the said ridge, there being a continuous circumferential weakening at the joinder of the skirt and rim for revolvement of the skirt as a lever when deformed by manual upward and outward lifting.
Claim 5
Dependent Claim
104 words
The container and reusable interlocked closure as set forth in claim 1, wherein the outward peripheral bead is a flattened roll adjacent the perimeter wall of the container and having a surface tangent to the opposed underside of the closure wall, wherein the rim and ridge formed on the cover conform to the said flattened roll configuration to which it is thereby interengaged, and wherein the skirt is substantially rigid with the said ridge, there being a continuous circumferential weakening at the joinder of the skirt and rim for revolvement of the skirt as a lever when deformed by manual upward and outward lifting.
