Definitions

  • One wall of the housing contains an opening through which the nozzle is displaced from its normal charging position within the housing to the dispensing position relative to a receptacle that is arranged externally of the housing. Tem perature-responsive means are provided for maintaining the interior of the housing at a desired storage temperature.
  • the reservoir and the dosage means within a storage housing that contains an opening through which the nozzle is transported during displacement between the charging position within the housing to the dispensing position external of the housing.
  • the means for displacing the nozzle between its charging and dispensing positions comprises a rocker am that is actuated by means arranged external of the housing, said rocker arm including a support portion that extends through the housing opening when the apparatus is in its normal storage condition to support the nozzle in the charging position relative to the reservoir.
  • the nozzle support portion of the rocker arm includes closure means arranged to automatically close the housing opening when the nozzle is in the charging position.
  • temperature-responsive means are provided for maintaining constant the temperature of the fluid within the storage chamber within the housing.
  • FIGURE of drawing which figure illustrates diagrammatically the preferred embodiment of the invention, certain parts being omitted for clarity of illustration.
  • the reservoir 1 is filled with the liquid to be dispensed via a supply tube 2 the lower extremity of which terminates at the desired liquid level to be maintained in the reservoir.
  • Dosage pump means of the type including a cylinder 3 and piston 4 are provided for withdrawing from the reservoir a desired charge of liquid 5 via nozzle 7 and flexible conduit 6.
  • the reservoir and dosage means are contained within the storage chamber 8 of a closed housing 9.
  • the nozzle 7 is initially maintained in a downwardly depending storage position, the free extremity of the nozzle being submerged beneath the level of liquid in the reservoir 1.
  • the nozzle is supported in this position by the nozzle support arm 11 that extends through opening contained in the right-hand end wall of the housing.
  • closure means 12 secured to the support arm 11 serve to automatically close the opening 10 when the nozzle is stored in the normal charging position.
  • the storage chamber 8 is sealed in a dustproof manner, the walls of the housing 9 preferably being formed of a heat-insulating material.
  • Temperature-responsive means in the form of a thermostat 18 control the setting of regulating valve means 19 to control the supply of temperature-modifying fluid to the chamber 8, thereby maintaining the storage temperature at a desired value (generally slightly less than ambient temperature). Vapors produced by evaporation of the liquid are removed from the chamber 8 by suction means 21.
  • nozzle support arm ll has integrally connected therewith a rocker arm 13 the ends of which are connected with a pair of pinions l4, l5 that me driven by the drive pinion 16.
  • nozzle-displacing means are arranged externally of the housing 9, and thus are readily accessible for inspection and servicing.
  • additional closure means may be provided for closing the opening 10 when the nozzle is withdrawn to the dispensing position.
  • the additional closure means (not shown) may be connected with support arm 11 adjacent the nozzle 7.
  • a dispensing apparatus of the type including dosage means (3-6) having a nozzle (7) operable alternately to initially remove a measured quantity of liquid from a reservoir (1) and to subsequently dispense said liquid quantity into a receptacle (17), respectively; and nozzle-displacing means (13-16) for displacing said nozzle between charging and dispensing positions adjacent said reservoir and said receptacle during said liquid removing and dispensing operations, respectively; the improvement which comprises housing means (9) completely enclosing said dosage means and said reservoir, said housing means containing an opening (10), said nozzle means nonnally being stored in the charging position relative to said reservoir;
  • said nozzle-displacing means being operable to transport said nozzle from said charging position outwardly through said opening to the dispensing position relative to a receptacle arranged externally of the housing.
  • nozzle-displacing means is arranged externally of the housing and includes a nozzle support arm (11) that extends through said opening to support said nozzle adjacent said reservoir when said nozzle is in its normal charging position.
  • nozzle-displacing means further includes a rocker arm (13) integrally connected with said support arm, and pinion means (l4, 15) for displacing said rocker arm in a parallel manner to displace the nozzle between said charging and dispensing positions.
