Abstract: A closure for a container having a circular opening defining an axis, the closure being securable to the container so as to close said opening, the closure having an o-ring sealing member mounted thereon so as to provide a seal with a sealing surface of the container, when the closure is secured to the container, the sealing surface extending around an upper surface or an internal surface of the container. The closure may comprise a bore feature which, in use, extends through the opening into the interior of the container and the o-ring seal may be provided on the bore feature. Various forms of closure are described, eg for closing a bottle neck and a wide-mouth closure. The closure may comprise an inner component and an outer component, eg a cap-on-collar closure, and the container preferably has no thread features on the exterior thereof so it is comfortable to drink from.

Abstract: A closure for a container having a circular opening defining an axis and a lip around said opening, the closure comprising: an inner component having a collar portion for locating about the exterior of the container beneath the lip of the container and a sealing portion which extends from said collar portion over an upper surface of said lip; and an outer component for fitting over the inner component and interacting therewith for releasably securing the collar portion under the lip, wherein the outer component has a skirt part for locating about the collar portion of the inner component, and the collar portion comprising a plurality of spaced apart radially moveable parts around its circumference pivotally joined at their lower ends by a ring extending around the entire circumference of the collar portion. The sealing portion may be formed of flexible material or may be formed of a relatively rigid material with a flexible sealing member, eg an o-ring, carried thereby.

Abstract: A security device for attachment to a container having external walls such that a transponder thereon is located externally of or adjacent to one of said external walls so as to avoid being shielded by a metal layer within the container (e.g. the metal layer within a disk such as a CD or DVD). The security device is arranged to trigger an alarm signal if the container is moved within the range of an alarm unit with the security device attached thereto, and has a releasable locking mechanism to secure it to the container such that release of the locking mechanism requires the use of authorized release means. In one embodiments the transponder is located in the vicinity of a window in a metal layer, e.g. at the centre of the disk.
