Abstract: A ventilator comprises an elongate strip (10) formed as a single component including an integral formation (19,23) extending adjacent an intermediate portion (13), the formation defining an opening (24,33) which is below openings (22) in the intermediate portion (13) thereby ensuring that there is no direct passage to and from the said openings (22) in the intermediate portion (13) in a direction normal thereto.

Abstract: A carrier (10) for a bottle comprises a plurality of containers (11) each having side walls (12,13,15,16) upstanding from a corresponding basal edge (19,20,21,22) of an inverted pyramidal base portion (18). When a bottle is received in a container (11), weight of the bottle causes walls (23) of the base portion (18) thereof to diverge one from another with a result that the side walls (12,13,15,16) converge towards and firmly engage the bottle.

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: Ventilating apparatus suitable for use with double glazed panels comprises an elongate cylindrical member having an outwardly circumferentially extending flange and adapted to receive removably a ventilating component therein and an annular member thereon. The cylindrical member extends through apertures in the panels and the flange and annular member are adhesively secured to adjacent panels thereby to seal the cylindrical member relative to the panels.
