Abstract
Abstract A lidded container comprising a segmental body portion and a lid pivoted thereto, the lid having an innermost planar surface and wherein when the lid is moved through 180* the innermost planar surface will sweep the inner surface of the body portion and remove the contents therefrom and present them for use upon the inverted lid of the container.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
64 words
A lidded container comprising a segmental body portion and a lid having an innermost planar surface, said lid being pivotally mounted about an axis coincident with the center of curvature of the segmental body portion, a portion of said lid being movable through the container closely adjacent the walls thereof to remove the contents from the container and present said contents on said surface.
Claim 2
Dependent Claim
64 words
A lidded container comprising a segmental body portion and a lid having an innermost planar surface, said lid being pivotally mounted about an axis coincident with the center of curvature of the segmental body portion, a portion of said lid being movable through the container closely adjacent the walls thereof to remove the contents from the container and present said contents on said surface.
Claim 3
Dependent Claim
60 words
A lidded container as claimed in claim 1 wherein the body portion is semi-circular in cross-section in a plane normal to the pivotal axis of the lid, the lid having a substantially plane inner surface and being adapted to move through substantially 180* whereby one half of the lids inner surface can sweep through the whole of the container body.
Claim 4
Dependent Claim
27 words
A lidded container as claimed in claim 2 wherein the body portion is hemi-spherical, the lid having a semi-circular portion which can sweep through the container body.
Claim 5
Dependent Claim
32 words
A lidded container as claimed in claim 3 wherein the lid is a planar disc of substantially the same diameter as the body portion and which can sweep through the container body.
Claim 6
Dependent Claim
27 words
A lidded container as claimed in claim 2 wherein the body portion is semi-cylindrical and the lid planar and rectangular or substantially rectangular in plan cross section.
Claim 7
Dependent Claim
28 words
A lidded container as claimed in claim 1 wherein the lid touches or scrapes the inner wall or walls of the container throughout its movement within the container.
Claim 8
Dependent Claim
23 words
A lidded container as claimed in claim 1 wherein means are provided for preventing reclosure of the lid after it has been opened.
Claim 9
Dependent Claim
42 words
A lidded container as claimed in claim 7 wherein such means provide a lip or ledge on the body portion over which the lid moves in one direction to open the container but past which it cannot return to close the container.
Claim 10
Dependent Claim
59 words
A lidded container as claimed in claim 8 wherein the lip or ledge may be provided with two opposed faces one of which is inclined to the path of movement of the lid but permits movement thereover, the other of which is disposed transversely of the path of movement to form an abutment past which the lid cannot move.
Claim 11
Dependent Claim
53 words
A lidded container as claimed in claim 9 wherein the lid is provided with a handle in the form of a planar extension which co-operates with a tapered slot in the wall of the body portion which slot provides some resistance to opening and maintains the lid closed until pressure is applied thereto.
Claim 12
Dependent Claim
48 words
A lidded container as claimed in claim 10 wherein the handle may be tapered in section, a slot in the opposed wall of the body portion also being similarly tapered whereby the handle can becOme irremovably locked in the opposed tapered slot when the lid is fully opened.
Claim 13
Dependent Claim
38 words
A lidded container as claimed in claim 1 wherein the lid is provided with a peripheral wall providing a greater depth closely adjacent the wall of the body and thus restricting flow of the contents past the lid.
Claim 14
Dependent Claim
32 words
A lidded container as claimed in claim 1 wherein the lid has opposed cylindrical spigots adapted to snap into corresponding apertures formed in the body portion to provide the pivotal connection therebetween.
Claim 15
Dependent Claim
16 words
A lidded container as claimed in claim 13 wherein the spigots are integral with the lid.
Claim 16
Dependent Claim
25 words
A lidded container as claimed in claim 1 wherein the segmental body portion is provided with a base or legs to render the body stable.
