Definitions

  • the present invention rapidly and efficiently dispenses viscous liquids into selected containers in only a fraction of the time and cost required by piston or peristaltic pump devices.
  • the invention is a device comprised of a dispensing container having either a fixed or removable dispenser bottom with multiple drainage holes adapted to correspond to selected pre-packaged containers or sorted containers to be filled.
  • a damming plate having drainage holes therein and slidable on a grooved track above said dispenser bottom is also included. While in the closed position, neither set of drainage holes (in the damming plate or the dispenser bottom) align which retains the viscous liquid in the container. In the open position, the drainage holes in the damming plate and dispenser bottom are aligned to allow the gravity transfer of the liquid into the selected containers placed below the device.
  • Figure 1 is a side view of a viscous liquid dispenser illustrating the damming plate in a closed position.
  • Figure 2 is a top view of the viscous liquid dispenser provided in Figure 1.
  • Figure 3 is a top view of the viscous liquid dispenser illustrating the damming plate in an open position.
  • Figure 4 is a side view of a dispensing container having an open top and bottom for use in a preferred embodiment of a viscous liquid dispenser wherein the dispenser bottom is removable and can be interchanged with other dispenser bottoms having different configurations, numbers or sizes of drainage holes.
  • Figure 5 is a side view of a preferred embodiment of a viscous liquid dispenser having an interchangeable, removable dispenser bottom and an interchangeable, slidable damming plate.
  • Figure 5A shows the removal of a first dispenser bottom and first damming plate having a first configuration.
  • Figure 5B shows replacement with a second dispenser bottom and second damming plate having a second configuration.
  • the viscous liquid dispenser 1 can be broken down into a dispensing container 6 having a dispenser bottom 2 with a multiplicity of drainage holes 3, a damming plate 4 with a multiplicity of drainage holes 3 and a grooved track 5.
  • the embodiment depicted by Figures 1-3 is adapted for and particularly useful in dispensing media into 23 different containers, the openings of which are depicted in Figure 3 as dotted lines.
  • the shape of the dispensing container and the number of drainage holes 3 can be easily altered in both the dispenser bottom 2 and the damming plate 4 so that the configuration and number of containers which can be filled at the same time can be altered.
  • the damming plate 4 is slidably mounted in a grooved track 5 along the inside wall of the dispensing container 6 just above the dispenser bottom so that the damming plate 4 can be slid between an open position wherein the drainage holes 3 of the damming plate 4 are aligned with the drainage holes 3 in the dispenser bottom 2 as depicted in Figure 3 and a closed position wherein the drainage holes 3 of the damming plate 4 are not aligned with the drainage holes 3 of the dispenser bottom 2 as depicted in Figure 2.
  • the viscous liquid dispenser 1 of the present invention is designed for dispensing any viscous liquid into multiple containers simultaneously.
  • the dispenser of the present invention is especially useful in dispensing hot media for laboratories where large numbers of containers containing media are used, for example in labs where Dr ⁇ sophila sp. are studied. It is also useful for the rapid dispensing of bacterial media.
  • the dispenser is useful in any area wherein there is a need to dispense a viscous liquid into multiple containers simultaneously, for example in the cosmetic or food industry.
  • the dispensing container 6 of the viscous liquid dispenser 1 of the present invention can have any size and shape adapted for selected containers to be filled with the liquid.
  • the dispensing container is comprised of a heat-retaining material, such as aluminum or stainless steel.
  • a heat-retaining material such as aluminum or stainless steel.
  • Other materials which may be used include, but are not limited to, copper, stable plastics and ceramic. Appropriate materials may be selected in accordance with the viscous liquid which will be dispensed. For example, if the viscous liquid must be sterile, a material which is suitable for autoclaving may be selected.
  • the dispensing container 6 has a dispenser bottom 2 having a multiplicity of drainage holes 3 therein. In one embodiment, as depicted in FIG 1-3, the dispenser bottom 2 is fixed and continuous with the sides of the dispensing container 6.
  • the dispenser bottom 2 is removable and can be interchanged with other dispenser bottoms having different configurations, numbers or sizes of drainage holes.
  • the dispenser bottom slides into a dispenser bottom groove 7 along the bottom of the inside walls of the dispensing container so that it can be interchanged with other dispenser bottoms.
  • the slidable damming plate 4 is also interchangeable so that the configuration, number and size of drainage holes in the dispenser bottom 2 and damming plate 4 can be matched accordingly.
  • On the inside wall of the dispensing container 6 is a grooved track 5 running parallel and just above the dispenser bottom 2.
  • a slidable damming plate 4 having a multiplicity of drainage holes 3 which is capable of moving between an open and closed position is mounted in the grooved track 5 parallel to and above the dispenser bottom 2.
  • the device has an open and a closed position. In the closed position, the drainage holes 3 in the damming plate 4 and the dispenser bottom 2 are not aligned so that any liquid placed in the dispensing container 6 is retained in the dispensing container 6.
  • the damming plate 4 is slid to a position wherein the drainage holes 3 in the damming plate 4 and the dispenser bottom 2 are aligned so that any liquid placed in the dispensing container 6 can flow through the drainage holes 3 and into containers placed beneath the viscous liquid dispenser 1 and aligned with the drainage holes 3 in the dispenser bottom 2.
  • the viscous liquid dispenser of the present invention is adapted to fit snugly over prepackaged disposable vials such as disposable polystyrene vials (AS-516, 10 x 10 row tray configuration; Applied Scientific, San Francisco, CA) .
  • disposable polystyrene vials AS-516, 10 x 10 row tray configuration; Applied Scientific, San Francisco, CA
  • Applied Scientific and many other vendors produce various polystyrene and K-resin prepackaged vials to which the device of the present invention can be readily adapted.
  • the viscous liquid dispenser is adapted to fit over glass vials such as 8-dram diameter Kimball Kimax vials.
  • the vials can be stacked, for example, in 8 x 19 rows in a stainless steel #3 mesh, 18 gauge welded wire basket, 14 1/2 inches wide x 10 1/2 inches deep x 2 1/2 inches high and having a 6 gauge top rim (Allentown Caging Co., Inc. (ACE) , Allentown, NJ) .
  • the device can also be adapted to fit over prepackaged Kimax vials, 144 per pack (model #60931-8, Fisher Scientific, Pittsburgh, PA) .
  • the viscous liquid device is adapted to fit over bottles, such as one-half pint bottles, which have been stacked in wire baskets .
  • Prepackaged containers can be filled using the device of this invention which is adapted to be of the size and shape dictated by the packaging dimensions.
  • Bulk containers can be stacked to any dimension needed by the user and the device adapted to a size and shape of appropriate dimensions.
  • petri dishes of any size and shape can be filled by placing the device upon a slightly elevated stationary or rolling platform.
  • the petri dishes can be placed on trays which are slidable under a stationary platform, or the device can be rolled down a table top rowed with dishes to achieve the same effect.
  • the device is adapted to a size appropriate for the dishes to be filled.
  • petri dishes which can be filled using the present invention include, but are not limited to, circular dishes with a diameter and depth in millimeters of 35 x 10, 50 x 9, 60 x 15, 100 x 15, 100 x 20 and 150 x 15 and square dishes 100 x 15 mm in size.
  • the device of the invention provides a rapid gravity transfer of viscous liquids into multiple containers simultaneously in a fraction of the time required by other devices.
  • the device can dispense media into vials of 10 to 15 ml or bottles of 35 to 50 ml at a rate of 4 to 15 seconds, as compared to 2 to 4 minutes for peristaltic or piston driven pump devices.
  • the present invention provides a more efficient and cost effective device for dispensing viscous liquids into a variety of containers.
