Abstract
A spray cap for a spray container constitutes a one-piece moulding of polymeric material and includes a cap plate in which a plurality of spray slits is formed.

- a cap plate;
- a cylindrical wall depending from the cap plate;
- a recess formed in the cap plate;
- an upwardly and inwardly inclined annular region formed in the cap plate about the recess;
- a plurality of spray slits formed in the inwardly inclined annular region of the cap plate;
- and
- a non-return valve extending from the recess, the non-return valve arranged to permit air to flow through said non-return valve in one direction which, in use, is towards an interior of the spray container but substantially to prevent the flow of air through it in the opposite direction;
