Definitions

  • This invention relates to a manually actuated liquid pump sprayer capable of being operating in both an upright position and in an inverted position by the provision of first and second oppositely extending fluid flow passages extending within the liquid in the container to which the pump sprayer is mounted in one of the upright and inverted positions, and extending into air in the container and the other of such positions.
  • Pump dispensers having only a single fluid flow passage comprising a dip tube extend from the pump into the liquid at the bottom of the container such that liquid is suctioned into the pump sprayer during its operation so long as there is liquid in the container and while the container is held in a position in which its bottom is located substantially below the pump sprayer.
  • U.S. patent 4,277,001 discloses a manually actuated pump sprayer adapted for upright and inverted spray by the provision of a three-way valve assembly mounted to the sprayer. Such assembly is, however, of complex structure requiring ball check valves associated with both oppositely extending fluid flow passages.
  • the adapter has confronting upright and inverted valve seats located within an adapter chamber in communication with the pumping mechanism, there being a single gravity shifting ball check valve provided for both valve seats.
  • the adapter for the manually actuated pump sprayer is a two-part structure comprising an elongated liner mounted to the pump body of the sprayer, and a hollow insert element coupled to the liner and extending into a terminal end of the liner.
  • the liner has an inner elongated coaxial cylinder which defines an adapter chamber and which is coupled to a valve controlled inlet passage of the pump body. A first of the valve seats projects into the adapter chamber from a wall of the cylinder.
  • the insert element supports a second of the valve seats which projects into the adapter chamber.
  • the liner of the two-part adapter has an internal longitudinal first groove which forms a portion of the second passage together with the pump body.
  • the insert element has an external longitudinal second groove which forms another portion of the second passage together with the liner, and the cylinder has an external longitudinal third groove which forms a portion of the first passage together with the insert element.
  • a manually actuated pump sprayer of any known type such as the finger actuated pump disclosed in U.S. patent 5,064,105 commonly owned herewith, is generally designated 10 in Fig. 1 has an internally threaded closure cap 11 to facilitate mounting the pump sprayer to a container 12 of liquid 13 to be dispensed.
  • the pump sprayer mounted to an externally threaded neck 14 of the container further includes a pump body 15 which extends into the container interior, and a dispenser head 16 having a discharge orifice (not shown) through which liquid product is sprayed upon depression of the head usually by the finger of the user for actuating the pumping mechanism, as disclosed in the aforementioned patent.
  • Other fingertip sprayers are capable of being utilized together with the adapter according to the invention.
  • the terminal end of the pump body which extends into the container forms an inlet passage 17, as is typical for fingertip pump sprayers of this type, which is valve controlled by, for example, a ball check valve 18 although other inlet valving may be provided.
  • a dip tube, such as 19, would normally depend directly from inlet passage 17 except that, in accordance with the invention, the dip tube extends from an upright/inverted adapter provided according to the invention, generally designated 21.
  • the adapter comprises a two-part structure shown in detail in Figs. 5 and 7, and is shown assembled together in Figs. 1 to 4.
  • an elongated liner generally designated 22 is shown as forming one part of the adapter, the liner having a first section 23 of a shape complementary to that of pump body 15 such that the liner can be conveniently attached thereto and be secured by a friction fit.
  • the liner has an internal cylinder 24 which defines an adapter chamber 25, the cylinder being mounted within the liner as by a plurality of spaced radial arms 26 more clearly shown in Fig. 6.
  • the cylinder is telescoped over sleeve 26 of the pump body, such that adapter chamber 25 communicates with inlet passage 17 of the pump.
  • the adapter comprises a pair of confronting, upright and inverted valve seats, a first valve seat 27 being shown in Fig. 5 as projecting into adapter chamber 25 from a wall of cylinder 24.
  • First section 23 of liner 22 has an internal longitudinal first groove 28 which together with pump body 15 forms a portion of a second fluid flow passage extending into the adapter chamber which will be described more fully hereinafter.
  • cylinder 24 has an external longitudinal third groove 29 extending between free end 31 of cylinder 24 and a transverse port 32 leading to valve seat 27.
  • the second part of the adapter according to the invention comprises a hollow insert element generally designated 33 in Figs. 7, 8 and 9.
  • the insert element has a first cylindrical section 34 which extends into second section 35 of liner 22 so as to be frictionally coupled together with the liner as shown in Figs. 3 and 4.
  • First section 34 of the insert element supports a second of the valve seats 36 which projects into adapter chamber 25.
  • First section 34 of insert element 33 has an external longitudinal second groove 37 more clearly shown in Figs. 8 and 9, the groove forming a second fluid flow passage 30 together with the liner when assembled.
  • Second groove 37 extends from the terminal end of portion 34 to port 38 which communicates with valve seat 36.
  • the insert element further has an external sleeve 39 into which one end of dip tube 19 is fitted for suspending the dip tube inside the container.
  • groove 29 forms together with portion 34 of the insert element a portion of first fluid flow passage 20 which is in communication with the interior of the dip tube.
