Definitions

  • This invention relates to viscous liquid dispensers and, in particular, to a dispenser containing at least two disposable cartridges of the viscous liquid with means for selectively dispensing only from a single cartridge at any one time.
  • Patent 4,130,224-Norman, et al. assigned to the assignee of the present invention.
  • the dispenser of Norman, et al. is used to dispense liquids such as soap from a single disposable cartridge.
  • the Norman, et al. dispenser has a sight window located adjacent to the bottom of the disposable cartridge so that a maintenance person can see that the cartridge needs to be replaced.
  • One problem with the single cartridge dispenser is that when the maintenance person looks at the window, the level of the fluid may be only slightly above the window with the result that the cartridge is completely used up before the maintenance person returns to service the dispenser.
  • U.S. Patent 2,619,386-Dalrymple discloses a trigger operated spray gun for simultaneously spraying two liquid solutions onto an object.
  • Dalrymple describes a trigger operated mechanism that simultaneous opens or closes a pair of fluid passages.
  • Dalrymple provides for individual adjustment of the fluid flow through each fluid passageway.
  • Another object of this invention is to provide a dispenser, having two disposable liquid cartridges, that can only dispense from one cartridge at a time.
  • a dispenser that can support two disposable liquid cartridges, each cartridge having an exit orifice through which fluid is dispensed when a pump portion of the cartridge is compressed.
  • the dispenser has a movable compression member located in the apparatus having a first position adjacent the pump portion of the first cartridge and having a second position adjacent the pump portion of the second cartridge.
  • the movable compression member is connected to a knob extending outside the dispenser which is used to move the compression member to the first position or to the second position to thereby select the cartridge that is compressed.
  • the dispenser has a movable dispensing member which compresses between the compression member and an opposing pinch surface in the dispenser only that cartridge pump portion that is adjacent the compression member.
  • the dispenser 10 of this invention has a rear base member 12, a front face 20, a top wall 22, bottom wall 24 and side walls 26, 28.
  • the base 12 is provided with a number of mounting holes, not shown, so that it can be mounted by means of bolts to a wall behind a washroom sink.
  • the front wall 20, top wall 22, bottom wall 24, and side walls 26, 28 of the dispenser 10 form a cover 14 that, as best illustrated in Figs. 4 and 4a, is pivotally connected to the base 12 by means of short hinge pins 30 on the cover 14 which extend into pivot holes 32 in support member 34 of base 12.
  • a shelf 36 for supporting two disposable viscous liquid cartridges 11a and 11b, such as soap or shampoo, side by side in the dispenser 10.
  • a typical viscous liquid cartridge 11 includes a flexible bag 13, a pump assembly portion 17 and a paperboard box 21 for controlling the shape of the flexible bag 13 both in the dispenser 10 and during shipment.
  • the pump assembly 17 consists of a connector element 23, a flexible tube 25 having one end connected to the connector 23 and the other end connected to a discharge element 27 which includes exit orifice 15 through which the liquid is dispensed.
  • the discharge element 27 includes a normally closed, spring loaded, ball valve as described in the aforementioned patent to Norman, et al.
  • a fitment 19b attached to the bottom of the flexible bag 13b provides an outlet port through which liquid can flow out of flexible bag 13b.
  • the connector element 23b of pump assembly 17b is inserted into the fitment 19b to provide fluid flow from the flexible bag 13b into the pump assembly 17b.
  • the filled flexible bag 13b, and attached pump assembly 17b are packaged inside the paperboard box 21b for shipment.
  • a handle 40 or dispensing means, is pivotally connected to the base 12 by means of short hinge pins 42 which extend into pivot holes 44 in support member 34 just below the shelf 36.
  • the support member 34 has a central opening 38 and the handle 40 is mounted so that it extends through the central opening 38 with the end 40d spaced a short distance below the bottom of the dispenser 10.
  • Assembled to the handle 40 is a spring loaded, pivoted pinch block 46.
  • Pinch block 46 has a pair of hooks 46a which fit around a bar element 40a of handle 40 so that the pinch block 46 can pivot around the bar element 40a.
  • a movable compression block 52 mounted within the cover 14 is a movable compression block 52.
  • a slide plate 54 is affixed to the compression block 52 and a knob 56 to provide a movable compression means.
  • the upper and lower edges of slide plate 54 move in slide tracks formed between horizontal guide walls 58 and inner surfaces 62 of cover 14.
  • the sloping side 66a of ledge 64 cooperate with a raised projection 52a on the upper edge 52c of compression block 52 to fix the location of the compression block 52 adjacent to the flexible tube 25b of cartridge 11b.
  • the sloped side 66a applies a compressive force to projection 52a and, because of slot 52b, the upper edge 52c of the compression block 52 yields to allow the projection 52a to slide along ledge 64.
  • the movable compression means reaches the position represented by the dashed lines 70, the projection 52a rides up the sloped side 66b which retains the movable compression block 52 in a second position adjacent the flexible tube 25a of the pump assembly 17a of the other cartridge 11a.
  • the dispenser 10 has a viewing window 72 located in the center of the front face 20 of the dispenser.
  • the viewing window 72 is located above knob 56 and even with the lower portion of the cartridges 11a and 11b supported in the dispenser 10.
  • each box 21 has two small rectangular cutouts 29 at the front lower corners of the box 21.
  • the cover 14 is unlocked, or unlatched as the case may be, and pivoted down about hinge pins 30.
  • Spent cartridges 11 are removed and replacement cartridges 11 are prepared by tearing out the vertical front wall strips 31 and the bottom wall strips 33, shown in Fig. 3, from cartridge boxes 21. Removal of those strips 31, 33 allows the pump assemblies 17 to be withdrawn from the boxes 21 so that they extend down from the lower left or lower right portion of the box 21 depending upon whether the cartridge 11 is placed on the support shelf 36 in the left or right position.
  • the rear wall 12 of dispenser 10 has two locating bosses 74 which fit into a locating hole 35 in the cartridge box 21 so that the two cartridges 11a and 11b are precisely positioned in the dispenser.
  • Locating bosses 74 also prevent shifting of the cartridges 11a and 11b in the dispenser 10 when replacing cartridges.
  • the discharge element 27 of each cartridge 11 is placed into the discharge element holder 50.
  • the bore of the discharge orifices 15 make a slight angle with the vertical so that fluid discharged from the orifices 15 is directed toward a common point at the same level as lower edge 40d of the handle 40.
  • the cover 14 is now pivoted upward to close the dispenser 10.
  • the knob 56 placed to the right as shown in Fig. 2
  • the movable compression block 52 will be located adjacent the pump assembly 17b of cartridge 11b.
  • Dispensing of the fluid from cartridge 11b commences by a user placing his hand palm upward with his fingertips behind the handle 40 and moving handle 40 in the direction indicated by arrow 41 in Fig. 4.
  • pinch surface 46c of pinch block 46 first pinches the upper portion of flexible tube 25b against compression block 52 to seal the tube 25b and prevent any back flow of fluid from the lower portion of pump assembly 17b into the flexible bag 13b.
  • pinch block 46 rotating about bar 40a and compression of spring 48 so that pinch block 46 builds up fluid pressure in the lower part of pump assembly 17b thereby causing fluid to be expelled through the exit orifice 15b into the palm of the user.
