Abstract: A system for introducing a flowable additive (3) from a capsule (1) to paint (4), varnish, woodstain or the like in a closed (preferably lidded) container (2) (for example a paint container) modified by the provision of a relatively easily openable inlet (9) into the container. Preferably the inlet is located in a lid (6). The capsule comprises a chamber (23) which defines a volume which contains the additive. The system is provided with means (25 and 34) for creating an opening in the chamber which can communicate with the inlet and means (preferably a compressible chamber) for positively expelling additive through the opening by contracting the volume which contains the additive. The capsule and container are also provided with co-operable locating means (10 and 30 with 25) which can co-operate to assist in locating the opening created in the chamber in communication with the inlet. Also a capsule and a closed container for use in the system and a method of introducing additive using the system.

Preferably the inlet (9) is located in a lid (6). Capsule (1) comprises a chamber (23) which contains the additive (3). The system is provided with means (25 and 34) for creating an opening in chamber (23) which can communicate with inlet (9) and means (preferably a compressibe chamber (23)) for expelling additive 3 through the opening. Capsule (1) and container (2) are also provided with co-operable locating means (10 and 24) which can co-operate to assist in locating the opening created in chamber (23) in communication with inlet 9. Also a capsule (1), a closed container (2) for use in the system and a method of introducing additive (3) using the system. Use of the system reduces the risk of spillage and splasing and is more suitable for use by inexperienced people.
