Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
199 words
An open-mouth container comprising: (a) a body composed of at least two longitudinal protruding portions and at least two longitudinal inset portions, said protruding and inset portions having inner surfaces which define the inner surface of the body, and (b) extensions of the protruding and inset portions of the body which extensions define the perimeter of the mouth of the container, (c) wherein the inner surface of each protruding portion lies outside the perimeter of the mouth and the inner surface of each inset portion lies within the perimeter of the mouth so that the mouth-defining extension of each protruding portion extends inwardly of the inner surface of the body and the mouth-defining extension of each inset portion does not extend inwardly of the inner surface of the body and (d) wherein the dimensions of the inner surfaces of the protruding and inset portions are such that, if the inset portions were notionally removed from the body and the protruding portions were notionally moved inwards until they touched along their longitudinal boundaries, the notional inner surface defined by the inner surfaces of the touching protruding portions would then be capable of being passed through the mouth of the container.
Claim 2
Dependent Claim
199 words
An open-mouth container comprising: (a) a body composed of at least two longitudinal protruding portions and at least two longitudinal inset portions, said protruding and inset portions having inner surfaces which define the inner surface of the body, and (b) extensions of the protruding and inset portions of the body which extensions define the perimeter of the mouth of the container, (c) wherein the inner surface of each protruding portion lies outside the perimeter of the mouth and the inner surface of each inset portion lies within the perimeter of the mouth so that the mouth-defining extension of each protruding portion extends inwardly of the inner surface of the body and the mouth-defining extension of each inset portion does not extend inwardly of the inner surface of the body and (d) wherein the dimensions of the inner surfaces of the protruding and inset portions are such that, if the inset portions were notionally removed from the body and the protruding portions were notionally moved inwards until they touched along their longitudinal boundaries, the notional inner surface defined by the inner surfaces of the touching protruding portions would then be capable of being passed through the mouth of the container.
Claim 3
Dependent Claim
31 words
A container according to claim 1 wherein the protruding and inset portions of the body are curved in transverse section, the protruding portions being of greater curvature than the inset portions.
Claim 4
Dependent Claim
14 words
A container according to claim 2 wherein the body of the container is bi-lobate.
Claim 5
Dependent Claim
22 words
A container according to claim 3 wherein the body of the container in transverse section has the shape of an oblate circle.
Claim 6
Dependent Claim
29 words
A container according to claim 4 wherein the maximum diameter of the inset portions of the body is at least 90% of the maximum diameter of the oblate circle.
Claim 7
Dependent Claim
25 words
A container according to claim 5 wherein the inset portions subtend an angle of from 20° to 80° to the principal axis of the container.
Claim 8
Dependent Claim
16 words
A container according to claim 1 wherein the inset portions of the body are re-entrant flutes.
Claim 9
Dependent Claim
21 words
A container according to claim 7 wherein each flute provides less than 10% of the internal transverse perimeter of the container.
