A concertina dispensing container with adaptor for the addition of water treatment chemicals to a heating system through the common traditional means of either a standard filling loop or alternatively, through a standard radiator point. The container consists of a concertina body 1 attached to a valve mechanism 2, 3. The container has a tapered screw thread so as to attach to a central heating system without the need for compound or sealing tape. The valve mechanism 2, 3 includes a plunger 3 provided with locating lugs. The container provides an advantage in that no draining down is required which leads to the chemical being easily added to a system with minimal disruption and time. Minimal force need be applied through the concertina bottle in order to directly discharge the contents into the heating system. The container also includes a barrel nipple adaptor to use when filling directly to a filling loop fitting, which allows the easy addition of chemicals to any heating system. |
