Abstract: A pressure control device for isolating a section of a conduit comprises a support member, a flexible cup member mounted to the support member, a first swellable element, the first swellable element adapted, upon activation by an activation fluid, to urge a first portion of the cup member outwards into engagement with a conduit surface and at least one bypass arranged to permit the activation fluid to bypass the swellable element and build up behind a second portion of the cup member.

Abstract: A sealing apparatus for sealing a well bore is described. The sealing apparatus comprises a sealing element adapted to be moved from a run-in configuration to a set configuration, a first back-up layer and at least one second back-up layer sandwiched between the sealing element and the first back-up layer. The at least one second back-up layer comprises a thinner material than the first back-up layer. The first back-up layer and the at least one second back-up layer are adapted to be moved from the run-in configuration to the set configuration under the action of the sealing element.

Abstract: A sealing element for a packer is described. The sealing element comprises an annular body having an internal surface defining a throughbore, the internal surface adapted to engage a mandrel having a mandrel diameter. The annular body internal surface defines first and second regions, the throughbore diameter of the regions being less than the mandrel diameter.

Abstract: A container (12) suitable for use in packaging pharmaceutical products such as tablets and capsules. The container (12) can be withdrawn from a box or sleeve (14) in a first direction X to a fully extended position whereby a user can remove any item stored by the container (12). The container (12) has a base (32) which includes an end portion (40) that remains substantially within the box or sleeve (14) when in the fully extended position. The base (32) carries at least one chamber formation (42) for containing an item to be removed by the user. The base (32) also has at least one stabilizing formation (44) on the end portion (40) that interacts with the box or sleeve (14) when in the fully extended position to resist pivoting of the container (12) relative to the box or sleeve (14). The or each stabilizing formation (44) differs in size and/or shape to the or each chamber formation (42), and has a length in the first direction X that is greater than or equal to its width in a second direction Y.
