Embodiment Construction

[0022] The device designed by the present invention is intended to be used in a liquid dosing device, and its purpose is to function immediately after each liquid is dispensed, so that air can be sucked into the rigid liquid storage tank R still containing liquid (shown in the figure part of the reservoir).

[0023] This liquid dosing device has an aspirator P, in particular with a cylindrical and conical pump body C, which is located below a support flange S, and the support flange is fixed on the The neck of the reservoir R also supports the sealing gasket surrounding the pump body C.

[0024] The liquid dispenser shown in the accompanying drawings further includes a push-type adjustment cap K attached to the nozzle T attached to the spray pipe of the air pump P and a metal assembly hoop D; the metal assembly hoop The piece D is folded into a waveform and tightly connected to the flange S of the air suction pump and the neck of the liquid storage tank R, so that the sealing...

Abstract

The invention concerns an air replenishing device for a liquid product dispenser equipped with a reservoir (R) and at atmospheric pump (P) provided in particular with a cylindro-conical body (C) and a support flange (S) fixed on the reservoir (R) neck supported on a sealing joint enclosing said pump body. The invention is characterised in that it comprises a flat ring (1) forming a joint whereof the feed edge (10) is sealingly supported outwards beneath a truncated shoulder (20) borne by the pump body (C) or said flange (S) and is adapted to be deformed under the effect of an internal vacuum for air replenishment.

Description

technical field [0001] The invention relates to an air intake device usable for sucking air into a liquid doser. Background technique [0002] Liquid dispensers are usually provided with a rigid liquid reservoir and an aspirator pump; in particular, the aspirator pump has a cylindrical and conical pump body and a support flange, which is assembled with a A hoop or an assembly cap cooperates so that the latter is crimped in a folded wave form to the neck of the reservoir and at the same time supports the sealing gasket surrounding the pump body. [0003] When dispensing a metered amount of liquid, or "dosing," a vacuum develops in the fixed-volume reservoir, which must be compensated by pumping a corresponding volume of air. To this end, the pump body is equipped with vent holes suitable for communicating the internal volume of the reservoir with the external atmosphere during the final stages of dispensing. [0004] There is another method that can be used to reestablish t...
