LIQUID SPRAYING APPARATUS Russian patent published in 1997 - IPC

FIELD: liquid dispensing devices such as air brushes. SUBSTANCE: liquid spraying apparatus has balloon 1 with neck 20. Inner surface of neck 20 is provided with annular rib 21. Apparatus is further provided with nozzle whose inlet end has first annular step 16 with inclined portion 15 and second annular step 18 spaced from first annular bead 16 and provided with inclined portion 17. Upon assembling of apparatus neck 20 of balloon embraces second annular step 18 of nozzle inlet end. Annular rib 21 of end neck 20 is arranged behind first annular step 16 to be coupled with inlet end of nozzle. During assembly of balloon 1 annular stop 19 projecting from outer surface of nozzle is brought into contact with end of neck 20 and neck 20 is forced to overlap inclined portions 15,17 of nozzle till neck end is seated adjacent to stop 19. At this point annular step is positioned behind projecting rib 21 of balloon 1 and balloon 1 is reliably retained on nozzle in spite of pressure created within balloon 1 or nozzle. EFFECT: increased efficiency and simplified construction. 7 cl, 3 dwg
