摘要:
Liquid dispensing apparatus comprises a tubular casing having at one of its ends a mouthpiece and an elongate cap, and at the other of its ends a nozzle having an orifice in communication with an expansion chamber bounded by sides which diverge away from the orifice. A liquid source including an elongate body and an absorbent nib (e.g. a felt-tipped pen) is located within the casing with side surfaces of the pen body spaced from internal wall surfaces of the casing to define an air flow passageway therebetween. First and second stop means are provided within the casing against the first of which a surface of the elongate body can abut to position the nib of the liquid source within or in close proximity to the nozzle orifice, and against the second of which a rearward end of the elongate body can abut to position the nib of the liquid source in a relatively airtight manner into one end of the elongate cap. The other end of the elongate cap is closed. Thus the liquid source can selectively be positioned with its nib within or in close proximity to the casing nozzle or with its nib effectively sealed within the elongate cap when the apparatus is not in use.
摘要:
The invention concerns a device for dispensing in spray form a fluid product, comprising a reservoir (13) containing the product to be dispensed and a spray outlet (16), said reservoir (13) including at least an actuating wall (131) deformable by application of a vertical force (F) so as to reduce the reservoir (13) internal volume, thereby exerting pressure on the fluid product to deliver it through the spray outlet (16). The invention is characterised in that said at least one actuating wall (131) has a predetermined threshold of resistance to deformation which must be overcome so as to deform it.
摘要:
Apparatus for dispensing a fine spray of liquid particles comprises a manually operated pump (1) connected to supply air under pressure directly to a nozzle (3) so positioned that air leaving the nozzle (3) is directed onto and over the nib (9) of a pen (8) releasably supported within a holder (5) with the pen (8) nib (9) in close proximity with the nozzle (3) outlet to cause liquid from the pen (8) to be dispensed as a fine particulate spray in air.
