Abstract: A piece of jewelry includes at least one chain having two ends, at least one of the two ends including a hollow clip fixed by a fixing device, the clip consisting of two half-shells, each half-shell including an extended edge delimiting a hollow internal space of the half-shell, the edges including notches into which the chain can be inserted, the half-shells being hinged together by an articulation between a closed position in which the two edges are brought together to close the clip and an open position in which the two edges are separated over at least part of their extents in order to allow a portion of the chain to be inserted between the two edges and through the internal space and so that the portion of the chain is retained in the clip by being blocked as to extraction and translation once the clip is closed.

Abstract: A convertible illuminated display case for drawing attention to an object or image. The display case includes a box having a front opening with a rim extending along at least a portion of its perimeter. The box has a removable front panel with a translucent wall. The display case also includes a support adapted to provide a base for displaying an object, and the support is further adapted for placement within the box. Rear cold light sources are disposed at the back of the box, and front cold light sources are disposed inside the box near the rim. A power supply device is connected to the front and rear cold light sources.

Abstract: A trim member is fixed to one sheet wall of a two sheet article of fabric or leather made by cojoining the two sheets around their edges, by locating a rigid plate between the sheet walls, forming an opening in the one sheet wall to bear the trim member over the plate and providing the trim member with a tongue which enters the opening and sandwiches an area of the one sheet wall overlying the plate between the tongue and the trim member.

Abstract: A device for preventing the self-unscrewing of a screw cap from a container, e.g. a bottle for use in pharmacy or perfumery and typically containing a volatile liquid product. The container has a neck having formed thereon a screwthread and a projection at or below the lower end of the neck screwthread. The cap screwthread has such a length that, during screwing of the cap onto the neck, the front or lower end of the cap screwthread strikes against the projection when the inside surface of the top portion of the cap is in contact with the top end of th neck. Final screw tightening of the cap causes the front or lower end of the cap screwthread to ride over the projection so that the cap is held more securely in a tightened condition on the container neck.

Abstract: An abutment face is provided in or adjacent the shoulder of a bottle or other container onto the neck of which a cap is screwed to seal the bottle. The cap has two parts--an inner part which screw-threadedly engages the neck and resiliently seals with it; and an outer part which is in driving engagement with the inner part. In order to ensure proper orientation of the outer part with the body of the bottle (if for example a flat surface on the outer part is to be aligned with a flat surface on the body of the bottle) while still ensuring a seal between the inner part and the bottle, a stop face is provided inside the outer part and, when the inner part has already sealed, abuts with the abutment face to cause such orientation. Upon initial capping of the bottle, the inner part is screwed tight onto the neck and the outer part is then forced over the inner part in a proper orientation until engagement between them is established.
