Abstract: A cap (20) is provided with a sealing pad (31) made of good barrier material for the contents of a bottle on which the cap is engaged. The pad has annular projections (33, 34) which sealingly engage with the inner wall (13) and the rim (15) respectively of a mouth of the bottle. The pad is retained in the cap by a retaining ring (30) projecting radially inwardly from the skirt (22) of the cap and this ring engages the outer wall (14) of the mouth to provide a third seal between the cap and the bottle.

Abstract: A container comprising a main container portion (2) having side walls (3) closed at one end and defining an open mouth at the other end, and a moulded rim member (4) having a plug portion (6) slidingly received in the mouth of the main container portion. The plug portion (2) has a projection (8) received in a corresponding groove (30) in the main container portion to retain the rim member in engagement with the main container portion and to provide first sealing means. A flange (22) extends from the plug portion inwardly of the container and terminates at a skirt which provides a seat for a removable plug-fitting lid (40).

Abstract: A container, for example a paint pot, is generally cylindrical, with an open end (2) into which a lid (6) plug-fits by engagement with a radially inwardly spaced skirt (45) which is connected to the wall (1) of the container by a flange (3). The flange forms an angle (A) within the wall (1) which is less than 90.degree., preferably 30.degree.. Having an angled flange facilitates manufacture of the container by injection molding techniques.

Abstract: An injection molded plastic container including a bail handle having projections adjacent each end engaging in holes passing through the peripheral wall of the container. Each projection has a cylindrical shank push-fitted in a corresponding hole, with the diameter of each hole being less than the external diameter of the shank.

Abstract: Ventilating apparatus comprises an elongate component (10) having complementary formations (19,20) at opposite ends whereby the component is adapted to be interlocked end to end in series with another component (10) or other components (10) and/or a connecting member (59,60) or connecting members (59,60). The component (10) and connecting members (59,60) therefore provide a modular system comprising one or more standard units (10) with left hand and/or right connecting members (59,60) enabling any combination to be connected end to end in series and thereby fit any size window.

Abstract: The tap is particularly intended for mounting in the neck of a plastics bag for support in a cardboard box. The tap has a hollow body (11) one end of which is open to the bag, the other end being closed by a resilient diaphragm (22). A valve stem (26) is integral with the diaphragm and carries a closure member (35), the diaphragm holding the member in sealing contact with the body to close the bag to the tap outlet (24). The diaphragm is also integral with elements (40, 41) which can be squeezed together to move the diaphragm to open the tap. Resilient means (43) is integrally formed between the elements (40, 41). A plate (50) prevents squeezing of the elements until it has been removed.

Abstract: A container having a body (10) provided with a mouth (14) defined by a lip (13) located radially inwardly of the main body wall (11) by a flange (12), and a lid having a skirt (23) for plug-fitting in the lip and a peripheral rim (24) projecting outwardly of the skirt so as to extend over the flange and permitting removal of the lid by a tool engaged between the rim and the flange, both the lid and the body being plastics mouldings wherein the surface (16) of the lip (13) engageable with the lid skirt (23) is convex in cross-section and in that the skirt has a complementary surface (28) which is concave in cross-section and extends from adjacent the rim (24).

Abstract: The container comprises a body, which is a one-piece injection moulding, having a cylindrical wall (12) with a smooth exterior without projections, a mouth (13) and a rim (14). At diametrically opposite positions on the cylindrical wall is provided an inwardly projecting boss (20) having no projection to the exterior. Each boss has a recess (21) open to the exterior and receiving in snap-engagement a spigot (32) on one end of a carrying handle (30) of yoke form. The spigot has annular bearing ribs (33, 34) journalled in the recess and has a locating blip (35) for engaging a depression (23) for releasably locating the handle relative to the body.
