Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
159 words
A container comprising a molded plastic body having an open end formed with an outwardly projecting peripheral lip; at least one plastic handle molded integrally with said body; integrally formed outwardly projecting lugs disposed on opposite sides of the body; plastic ligament hinge portions molded integrally with said lugs and with said at least one handle, said hinge portions being spaced outwardly from said lip, and said at least one handle having a shape conforming to part of said lip, and being movable about said hinge portions between an inoperative position at one side of the container body and an operative, carrying, position extending across the open end of the container body, and a lid having a peripheral flange which fits over the lip of the body, each handle-supporting lug being formed with a recess facing towards the open end of the container body and adapted to accommodate the flange of the container lid when the latter is fitted.
Claim 2
Dependent Claim
159 words
A container comprising a molded plastic body having an open end formed with an outwardly projecting peripheral lip; at least one plastic handle molded integrally with said body; integrally formed outwardly projecting lugs disposed on opposite sides of the body; plastic ligament hinge portions molded integrally with said lugs and with said at least one handle, said hinge portions being spaced outwardly from said lip, and said at least one handle having a shape conforming to part of said lip, and being movable about said hinge portions between an inoperative position at one side of the container body and an operative, carrying, position extending across the open end of the container body, and a lid having a peripheral flange which fits over the lip of the body, each handle-supporting lug being formed with a recess facing towards the open end of the container body and adapted to accommodate the flange of the container lid when the latter is fitted.
Claim 3
Dependent Claim
73 words
The container defined in claim 1, including a radially inwardly projecting lip formed on the lid flange, wherein the lip of the container body is formed at its outer end with a depending skirt portion, each handle-supporting lug having a root portion spaced radially inwardly from the said skirt portion to allow snap-engagement of the lipped flange of the lid over the skirt portion upon fitting of the lid to the container body.
Claim 4
Dependent Claim
28 words
The container defined in claim 1, wherein the container body, the ligament hinges, and said at least one handle are molded with said handle in its inoperative position.
Claim 5
Dependent Claim
41 words
The container defined in claim 1, wherein the body is molded integrally with two handles, the ligament hinges supporting said handles being arranged so that the handles are disposed symmetrically on opposite sides of the container body in their inoperative positions.
Claim 6
Dependent Claim
63 words
The container defined in claim 4, wherein the two handles are molded integrally with two supporting lugs arranged on opposite sides of the container body, the ligament hinges connecting each lug to the two handles defining respective parallel hinge axes which are separated by the thickness of the lug, so that the two handles lie alongside each other in their operative, carrying positions.
Claim 7
Dependent Claim
37 words
The container defined in claim 4, wherein the container has a rectangular shape, the ligament hinges defining the hinge axes of the two handles being parallel to each other and equidistant from opposite sides of the container.
