<p>A material supply assembly for use with a spraying device, which material supply assembly includes a housing (12) of stiff material comprising a side wall (13) having a top end (14); and a pre-filled container (19) comprising a stiff annular lip (22) adapted to be positioned along the top end (14) of the side wall (13), and a flexible portion (20) fixed to the annular lip (22) and adapted to extend into the cavity of the housing (12) when the annular lip (22) is positioned along the top end (14) of the side wall (13). The flexible portion (20) contains a quantity of material. A membrane (26) extends across and is sealed to the annular lip (22) to retain the material. 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 (22) positioned on the top end (14) of the container (12), and at the other end of which is a portion (35) adapted to engage the inlet port of a liquid spraying device. Means are provided for securing the peripheral part to the housing (12) with the annular lip (22) therebetween. A piercing structure (32) projects from the central portion and has a distal end portion (34) adapted to pierce the membrane (26) as the peripheral part is engaged with the annular lip (22) positioned on the top end (14) of the housing (12).</p> |
