A material supply assembly for use with a spraying device, which material supply assembly includes a housing of stiff material comprising a side wall having a top end defining an opening into a recess defined by the housing; and a pre-filled container comprising a stiff annular lip adapted to be positioned along the top end of the side wall, and a flexible portion fixed to the annular lip and adapted to extend into the cavity in the housing when the annular lip is positioned along the top end of the side wall. The flexible portion has an inner surface defining a cavity, and a quantity of material is within the cavity in the flexible portion. A polymeric membrane extends across and is sealed to the annular lip to retain the material in the cavity. The material supply assembly also includes an adapter assembly having a through opening, at one end of which is a transverse portion including a peripheral part adapted for engagement with the annular lip positioned on the top end of the container, and at the other end of which is a portion adapted to engage the inlet port of a liquid spraying device. Means are provided for securing the peripheral part to the housing with the annular lip therebetween. A piercing structure projects from the central portion and has a distal end portion adapted to pierce the membrane as the peripheral part is engaged with the annular lip positioned on the top end of the housing.
A cup (6) for spray guns, comprising a disposable container (8) joined in removable fashion to a lid (5) with axial outflow fitting (7), independent of the cup and integrated with the body (4) of the gun (1), and a lining element (18) whose shape is complementary to that of the lid (5) and which is inserted in removable fashion within said lid (5) between the container (8) and the outflow fitting (7).
A connector system for releasably securing a reservoir to a spray gun includes hook members on a lid of the reservoir that engage a flange of an inlet adaptor on the spray gun with a push/twist action to secure the reservoir to the spray gun. A retainer clip mounted on the inlet adaptor is movable between an inoperative position to allow the reservoir to be connected to and disconnected from the spray gun, and an operative position in which the clip blocks release of the reservoir. The clip provides security against accidental release of the reservoir in use of the spray gun.
A fluid supply assembly having a measuring guide comprising a fluid container, a lid, and a measuring guide. A method of measuring fluid components in a fluid supply assembly is also described.
A fluid supply assembly. The fluid supply assembly includes a disposable cup and lid, and a reusable cup holder and outer lid. A method of preparing a fluid supply assembly for use with a fluid supply applicator is also described.
