Container for spraying liquids by hand - has spray formed by Venturi effect when container squeezed and spray head movable downwardly to admit air (BR 1.11.77)

摘要

The container is used for spraying liquids by hand and is made from a flexible fabrics. The spray is formed by the Venturi effect of internal air expelled through side holes (10), drawing liquid with it. A cap (1) clips over the container neck (2). The lower part of (8) the spray head forms a diaphragm (12) held by the cap. The head contacts (11) the inner face (7) of the cap, the spray being expelled through a central orifice (6, 9) and pick-up tube (5). Replacement air returns rapidly into the container through holes (13) in the diaphragm, the spray head being pulled downwards by the inner vacuum.
