Definitions

  • the lower check valve actuator is mounted to the actuating arm which will cause a delay of the closing of the lower check valve, during retraction of the actuating arm, by restricting the action of the lever arms which stretch closed the discharge port.
  • Tensioning pins are used as the lever arms.
  • the actuating arm 24 is pivotably connected to the front cover 14, near its top at pin connectors 28a, 28b (see Figure 6). Inside the dispenser 10 between the front cover 14 and the back plate 12 is located an elongated conical trough 32 having a wide open top end 34, generally straight sides 36, a cone section 38 and a bottom opening 40. The trough 32 is supported in the dispenser by clips 44 attached to the back plate 12.
  • a film pouch 48 Placed within the trough 32 is a film pouch 48 having a sealed top end 50, a liquid containing volume or straight section 52, a generally conical section 58 below the straight section 52, and a cylindrical pathway 60 terminating in a narrow channel section 62 having an aperture 64 at its terminal end.
  • a tube 70 Mounted within the cylindrical pathway 60 is a tube 70 having a sufficient thickness to retain a structural memory after collapsing. That is, the tube will spring back to its tubular shape after being compressed.
  • Figure 2 illustrates another embodiment of the dispenser 10 described with regard to Figure 1, referred to as dispenser 160.
  • the trough 32 is supported within the dispenser 160 by a plurality of clips 166.
  • a film pouch 170 is similar to the film pouch 48 except for a substantially shorter polymeric tube 172 located therein.
  • the tube 172 provides V-shaped notches 72 at a top end thereof and notches 178 at a bottom end thereof.
  • a front portion of the tube 172 has a shorter length than a rear portion 172b.
  • Figure 5 illustrates the functioning of the check valve 106.
  • the pins 116, 118 are shown extended through the holes 136, 138 in the narrow channel section 62 of the pouch.
  • the pins have annular slots 262a, 262b to hold the narrow channel section 62 thereon.
  • the pins have distal ends 280, 282 with surfaces 280a, 282a tapered outwardly.
  • FIGS 6 and 7 illustrate the tubular section 260 that is used in the present invention.
  • V-shaped notches are formed both in the top section and the bottom section.
  • an angle B is provided for the V-shaped notches.
  • One actuator of the system of the present invention has several features which achieve these inventive advantages.
  • the portion of the pump actuator arm at its upper end described as the upper check valve actuator tip portion, progressively engages and compresses the upstream end of the pump tube against a "pump anvil" projection on the dispenser back molding.
  • the progressive engagement involves slidably engaging the contoured surfaces of the anvil and the tip in a manner which utilizes the physical properties of the polymer that is used to mold the actuator (high memory, low set retention) and the contoured shapes of the two parts in a rolling, wedging effect, rather than a knife effect. Because of the engagement, a reduced resistance to the closing of the pump sleeve is achieved by the unique notching at the point of engagement with the tip and anvil.
