having a first sealing portion which is contiguous with the top portion. The rib further includes a second sealing portion that is separated from the top portion by the first portion and which, prior to attachment of the closure to the container, extends inwardly to a free edge. The closure further has a continuous nub member extending downwards and outwards from the underside of the top portion that is positioned radially inwards of the first sealing portion. On attachment of the closure to the container end portion, the nub member seals with the inner surface of the container end portion and the sealing rib seals the outer surface.

brittle component, such as glass is ultrasonically welded to a body. The moulded edge and body are comprised of ultrasonically weldable materials. Locating features permit accurate positioning of the lid relative to the body, and energy directors can be included. Pins of various lengths having a relieved portion and a protruding portion can also be hermetically sealed to the body. The pins can be within channels, which can hold a sealant. The body can include a device that is electrically connected to the pins. Patent number: WO 03/023821 Inventors: S.W.Crane, M-S.Jeon, M.E.Doty Publication date: 20 March 2003
Annulus seal Applicant: FMC Technologies Inc, USA. This patent describes a metallic seal for sealing the annulus between two concentric components, such as the casing and a riser in an oil well. The inner component, 406, has a tapered outer surface, 410. The outer component, 408 has an inner surface that is concentric with the inner component. The metallic

sealing element, 402, has a tapered inner surface, 416, that substantially matches the taper on the outside diameter of the inner component. The seal is assembled to be an interference fit by means of press or shrink fitting. A further embodiment allows for a galling fit of the seal. Fitting the seal onto the taper creates the sealing contact on the inside diameter of the outer casing. The design of the seal is such that increasing pressure in the annulus above the seal will increase the sealing force at the seal lip, 426. Provision is made for an elastomeric secondary sealing means, such as an O-ring. The metallic component may be manufactured from a range of materials with yield strengths from 450MPa to 1000MPa depending on the pressure and the corrosion resistance required. Various alloys including, nickel/chromium, beryllium copper and nickel copper are included. A number of variations on the arrangement are included, there are a total of 82 claims. Patent number: WO 03/024634 Inventor: Q.S Zheng Publication date: 27 March 2003
