Spray gun with rotatable reservoir

A liquid spraying apparatus comprising a spray gun having an inlet, a reservoir for a liquid to be sprayed, connector means connecting an outlet from the reservoir to the inlet of the spray gun to permit the liquid to be withdrawn from the reservoir in use, the connector means being releasable for detaching the outlet from the inlet, and permitting rotation of the outlet relative to the inlet while the reservoir is attached to the spray gun without compromising the integrity of the connection between the reservoir and the spray gun, wherein the connector means comprises at least one resilient clip on one of the reservoir and spray gun engageable with an abutment on the other of the reservoir and spray gun to resist axial separation of the reservoir and spray gun while permitting rotation of the reservoir outlet relative to the spray gun inlet, wherein the reservoir outlet and spray gun inlet are connectable by push fit and the resilient clip comprises a spring leg arranged to extend substantially parallel to the direction of movement of the reservoir outlet towards/away from the spray gun inlet and the abutment comprises a ledge transverse to said direction of movement such that the spring leg engages behind the ledge when the reservoir outlet is connected to the spray gun inlet and can rotate relative to the ledge while resisting axial separation of the reservoir outlet from the spray gun inlet, and wherein one of the spring leg and ledge has a cam face arranged to deflect the spring leg when the reservoir outlet is connected to the spray gun inlet to allow a distal end of the spring leg to pass the ledge and latch behind the ledge to secure releasably the reservoir to the spray gun.
