Abstract

Abstract The invention relates to improvements in securing a liner within a flexible container such as an intermediate bulk container. The container has first attachment means in the form of a connecting ring and mounting straps therefor attached to the exterior of the container adjacent the upper and lower peripheries thereof. The linear has corresponding second attachment means at the top and bottom thereof. The bottom liner attachment means includes a strap which can pass through a corresponding opening ajacent the bottom of the container and which is provided with an appropriate connector for connection to the corresponding ring of the first attachment means. The top liner attachment means is similar to the bottom liner attachment means and, if no cover for the container is required, will pass over the upper edge of the container for connection to an appropriate upper connecting ring. If a cover is provided appropriate openings may be provided to pass the straps of the second attachment means from the interior to the exterior. In this manner a light-weight container may be used; the linear can bear a portion of any loads placed on the container; the liner can be readily removed for repair or replacement; and a container which is otherwise not waterproof can be made waterproof by the addition of a waterproof liner.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 149 words
An intermediate bulk container including at least side walls having upper and lower peripheries respectively and a bottom wall, and a releasably mounted internal liner, which comprises:- a plurality of first attachment means secured externally to the side walls of the container adjacent the upper and lower peripheries thereof, and spaced uniformly around said container; a plurality of first openings through said container adjacent said bottom wall, there being one opening associated with each first attachment means adjacent said lower periphery; and a plurality of second attachment means secured to said liner adjacent the top and bottom thereof, there being one second attachment means for each first attachment means; whereby, with said liner located within said container each of said second attachment means can extend from the interior of the container to the exterior thereof and can be releasably secured to a corresponding one of said first attachment means.
Claim 2
Dependent Claim 149 words
An intermediate bulk container including at least side walls having upper and lower peripheries respectively and a bottom wall, and a releasably mounted internal liner, which comprises:- a plurality of first attachment means secured externally to the side walls of the container adjacent the upper and lower peripheries thereof, and spaced uniformly around said container; a plurality of first openings through said container adjacent said bottom wall, there being one opening associated with each first attachment means adjacent said lower periphery; and a plurality of second attachment means secured to said liner adjacent the top and bottom thereof, there being one second attachment means for each first attachment means; whereby, with said liner located within said container each of said second attachment means can extend from the interior of the container to the exterior thereof and can be releasably secured to a corresponding one of said first attachment means.
Claim 3
Dependent Claim 42 words
A container according to claim 1 wherein each of said first attachment means includes a pair of first straps each having one end thereof connected to a connecting ring and the other end thereof secured to the side wall of said container.
Claim 4
Dependent Claim 40 words
