A container for fluids which is closed by a cap which is inserted into the neck of the container. A coupling member is interposed between the neck and the cap which is fitted to the container after it has been formed. The coupling member is readily attachable to the container from its exterior without requiring any modification to the container and has a central bore to receive the cap.
A closure is used for selectively closing an opening of a container, the container including a tubular collar defining an opening and surrounded at the opening by an annular collar flange. An embossment includes a tubular collar retainer having an outer diameter slightly less than an inner diameter of the container collar and defining a through passage. A cap is threaded into the through passage to close the same. An annular retainer flange extends outwardly from an outer wall of the collar retainer and is seated on the collar flange incident to the retainer being inserted in the container collar. The retainer flange is secured to the collar flange by vibration welding so that the cap closes the container opening.
A bush for a valved closure unit of the kind used in beer kegs comprises two-parts and when in a unit engages an opening in the keg. One part of the bush which engages the opening, is in the form of a hot brass stamping or stainless steel or aluminium casting. The other part of the bush is of stainless steel and is held in the first part by an interference fit and/or interfitting ribs and grooves and/or adhesive. The interstices between the parts are sealed by a sealant. A closure unit employing such a bush has a valve seat formed by an internal flange on the second member and a valve is guided as it moves towards and away from the seat.

A plastic drum and closure assembly for providing a replaceable two-inch straight pipe thread flange includes a synthetic material drum having a drum end which is molded with a two-inch buttress thread opening and an internally splined raised annular boss which is suitably designed and arranged to receive an externally splined plastic flange member which includes an internal series of two-inch straight pipe threads. The flange is secured to the raised annular boss by means of a metal retaining ring which is shaped and conforms to the outer lip portion of the flange thereby providing an outwardly-deformable surface and an inner back-up surface. Installation of the flange into the raised annular boss begins with the alignment of the internal and external splines and once the flange is fully seated within the raised annular boss the metal retaining ring is crimped so as to conform the outwardly radiating lip portion of the flange to the lip portion of the raised annular boss thereby providing a liquid-tight interface between the two members. The style of the retaining ring and the shape and contour of the raised annular boss permit the plastic flange to be removed, once damaged, and a replacement flange to be installed and reassembled.
A filter-retainer assembly performs both the function of filtering the inlet fuel flow and retaining the inlet tube O-ring of a top-feed fuel injector of the type commonly used in fuel injection systems of internal combustion engines. The assembly has a snap-on, snap-off feature.
