<p>A bottle 1 for the introduction of an additive into a central heating system, said bottle comprising a hollow body 2 with an elongate outlet spout 3. One end of the spout is attached to the body adjacent one end of the body via a swivel joint 4, such that the spout is manually rotatable with respect to the body, the other end of the spout is externally threaded 6 such that the spout diameter and threads will enable that end of the spout to be screwed into a tapped hole of a central heating radiator (fig 2, 7) or towel heater, with a removable closure cap 8 screwed onto the tapped end of the spout. The bottle may comprise a carry handle and the top wall may be inclined such that, when the bottle is inverted, the contents move downwards to the spout. A method of use is also claimed, where the bottle body is located below the tapped hole whilst the spout is threadably secured to said tapped hole. Once secure, the bottle body is manual rotated about the swivel joint so the body is inverted and the contents may be dispensed.</p> |
