Definitions

  • This invention relates to a trigger actuated pump arrangement which can be connected to a fluid container for dispensing the fluid in the container.
  • a manually operable liquid dispensing pump for use and incorporation on a container for a liquid to be dispensed comprising in combination:
  • the invention encompasses a combination of the present pump arrangement and a fluid container.
  • FIGS 1 and 2 show a pump mounted on a container 14.
  • the pump 10 is held onto the container neck 12 by a screw cap 24.
  • screw cap 24 could be replaced with any conventional closure, such as a snap-on closure.
  • the pump 10 includes a housing, generally indicated by reference number 16, which housing is preferably one-piece and integrally molded and has, preferably, an integrally molded trigger 18.
  • trigger 18 can be connected to the pump assembly or housing 16 by any conventional means, for example, such as by pinning or bolting.
  • Housing 16 has a generally horizontal portion 16a and a generally vertical'portion 16b.
  • Horizontal portion 16a forms an approximate right angle with vertical portion 16b.
  • horizontal portion 16a is approximately horizontal and vertical portion 16b is vertical.
  • Horizontal portion 16a has a generally horizontal cavity 19 therein for receipt of a bladder 20 and a nozzle 22.
  • cavity 19 has a tapered upstream end 19b for receipt of the tapered end 20a of bladder 20.
  • a vertical channel 21 in vertical portion 16b connects a suction tube 28 with cavity 19.
  • the end 20a of bladder 20 covers the upper end of channel 21.
  • Suction tube 28 is connected to the lower end 16c of vertical portion 16b.
  • the lower end 16c of vertical portion 16b can be tapered so that it may be easily inserted in the top of cap 24 and may be provided with a shoulder 16d for force fitting into hole 24a in cap 24.
  • the lower end 16c of vertical portion 16b could also be threaded to screw into a conventional closure, or formed in any other conventional manner.
  • Bladder 20 which is seen separately in Figures 12 and 13, is made of an elastic material such as rubber, plastics material, or other flexible material, which can be depressed and relaxed and expanded to regain its natural profile.
  • the bladder has a cylindrical end port 20b on its left hand end or downstream end which cooperates with a post 50 (see later) to function as a one-way nipple-type valve that allows fluids to pass outwardly only from the bladder.
  • the upstream end or right hand end 20a of bladder 20 is tubular in shape and open at the end.
  • bladder 20 has a relatively thin wall thickness as can be seen in Figure 3 at 20c so that the end 20a of bladder 20 can act as a flapper valve as shown in Figure 6.
  • the section 20c may be tapered to aid in assembly.
  • Nozzle 22 Located downstream from bladder 20 is a nozzle 22.
  • Nozzle 22 can be any conventional type of nozzle and has an orifice 22a therein.
  • a preferred nozzle is that disclosed in U.S. Patent Specification No. 4,257,561.
  • Nozzle 22 has a hollow cavity 111 therein for receipt of a conduit 122.
  • Conduit 122 is shown in detail in Figures 8 and 9.
  • Conduit 122 has an upstream end 122a which can be glued or force fitted into the downstream end of housing 16.
  • Conduit 122 has a hollow channel 122b therein through which liquids flow when trigger 18 is depressed.
  • Conduit 122 has a solid post 50 in the upstream end thereof.
  • Two channels 122c-122c are formed in the upstream end for liquids to enter channel 122b.
  • Flexible valve member 128 has a central, generally hemispherical portion 130 surrounded by apertures 132.
  • the apertures 132 provide fluid flow passages between the outlet conduit 122 and the aperture 22a in nozzle 22 when flexible outlet valve 128 is open.
  • Valve 128 is opened and closed by screwing nozzle 22 outwardly and inwardly, respectively.
  • the main housing 16 has a thin leaf-like strip 30, as shown in Figure 3, molded into the open area 31 into which the upper portion 18a of trigger 18 rests in the normal, undepressed position.
  • the leaf-like strip 30 acts as a skid plate for upper portion 18a and easily deforms upwards when trigger 18 is depressed as indicated in Figure 4.
  • Strip 30. can include a bump or raised portion 30a to increase the volume of liquid displaced from bladder 20.
  • the thin leaf-like strip 30 can be omitted to permit the upper portion 18a of trigger 18 to contact bladder 20 directly and/or a burp may be incorporated on the upper portion 18a of trigger 18 to increase the volume of liquid displaced.
  • Housing 16 can be seen to have a recess 17 therein.
  • Recess 17 is a hollow portion in housing 16 which is provided for the purposes of saving material and decreasing cost of the housing.
  • the front portion of recess 17 can best be seen in Figure 1 to lie directly behind the trigger.
  • a similar recess 17 is provided on the back part of housing 16.
  • a vent 45 allows air to enter the container 14 when the pump is actuated.
  • the path of the air flow is from the atmosphere through slots 33, shown in Figure 5, into the space 32, shown in Figure 1, which is immediately behind thin leaf-like strip 30, and downwards through vent 45.
  • Such a means for venting is desirable when the pump has an air-tight seal with the container.
  • the preferred complete pump assembly includes a relatively small number of component parts, i.e. a main housing with an integrally formed trigger, a nozzle, a bladder, a screw cap, a gasket, and a dip tube.
  • the main housing snap fits into the screw cap and incorporates a leakproof seal.
  • the screw cap preferably has integrally molded score marks (not shown) on the underside which allow air to enter the container between the gasket and cap to displace fluid discharge by the pump.
  • the preferred pump of the present invention can thus be seen to be easily assembled.
  • To assemble the pump one merely inserts the bladder 20 into cavity 19 and then inserts conduit 122, valve 128, and nozzle 22 into cavity 19 downstream from the bladder 20. Dipper tube 28 may then be forced upwardly into channel 21.
  • the entire pump may, if"desired, be made entirely of plastics material as is well known in the art.
  • the bladder of course, should be made of a flexible material which will return to its natural profile after being deformed and depressed.
