Abstract
Abstract A container comprises an inner casing and an outer casing and an elongate member extends through a container space formed by the interior of the inner casing. The elongate member is secured to an upper and lower portion of the container, and of the casings, at least the inner casing comprises a pliant or flexible material. For the purpose of relieving the inner casing of stresses and strains, the elongate member is anchored to the upper portion of the container solely at the outer casing, while the upper portion of the inner casing is displaceable along the elongate member. In such a container only the outer casing is subjected to wear, and to the stresses and strains occurring when a full container is lifted. Filling of the container is facilitated by the displaceability of the upper portion of the inner casing along the elongate member.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
88 words
A container, comprising an inner casing and an outer casing which encloses said inner casing, wherein an elongate member extends through a container space formed by the interior of said inner casing and is secured to an upper portion and a lower portion of the container, of which casings at least the inner casing comprises a pliant material, and wherein the elongate member at said upper portion is secured solely to the outer casing, and the upper portion of the inner casing is displaceable along the elongate member.
Claim 2
Dependent Claim
88 words
A container, comprising an inner casing and an outer casing which encloses said inner casing, wherein an elongate member extends through a container space formed by the interior of said inner casing and is secured to an upper portion and a lower portion of the container, of which casings at least the inner casing comprises a pliant material, and wherein the elongate member at said upper portion is secured solely to the outer casing, and the upper portion of the inner casing is displaceable along the elongate member.
Claim 3
Dependent Claim
29 words
A container according to claim 1, characterized by means for limiting the extent to which the upper portion of the inner casing can move relative to the elongate member.
Claim 4
Dependent Claim
37 words
A container according to claim 2, characterized in that the means for limiting said movement of the upper portion of said inner casing along said elongate member comprises a connection between the inner and the outer casing.
Claim 5
Dependent Claim
52 words
A container according to claim 1 or 2, characterized by a device actuatable from outside the container in a manner such as to releasably secure the upper portion of the inner casing in the neighbourhood of the location at which the elongate member is secured to the upper portion of the container.
Claim 6
Dependent Claim
80 words
A container according to claim 4, characterized in that the device actuable from outside the container comprises a further elongate member which is connected to the upper portion of the inner casing and extends therefrom longitudinally displaceably through the upper portion of the outer casing to a location externally thereof, and which further elongate member is releasably fixable in a position in which the upper portion of the inner casing is located adjacent the upper portion of the outer casing.
Claim 7
Dependent Claim
34 words
A container according to claim 5, characterized in that the further elongate member can be fixed in a second position in which it permits limited displacement of the upper portion of the inner casing.
Claim 8
Dependent Claim
32 words
A container according to claim 1, characterized in that the casings have the form of pliant hose-like elements gathered at their open ends around the elongate member extending through the container space.
Claim 9
Dependent Claim
33 words
A container according to claim 7, characterized in that the upper portion of the inner casing is gathered around an intermediate member displaceably mounted on the elongate member extending through the container space.
Claim 10
Dependent Claim
69 words
A container according to claim 7 or 8, characterized in that the elongate member extending through said container space is enclosed in a tube of soft pliant material, which extends between the upper portion of the inner casing and the location at which the elongate member is secured to the lower portion of the container, and which shields said elongate member from the container space in a liquid-tight fashion.
Claim 11
Dependent Claim
63 words
A container according to claim 1, characterized in that the elongate member extending through the container space extends displaceably through an opening at the upper portion of the outer casing and forms between said opening and the location at which the elongate member is secured to the upper portion of the container a loop for receiving a lifting device for lifting said container.
