Definitions

  • the container has a concavity in one of its sidewalls which forms the dispensing tray for the processing liquid.
  • the concave sidewall is punctured by a pump arrangement which supplies the processing liquid to the dispensing tray from the interior of the container.
  • the container has raised end walls interconnected with the concave sidewall for preventing the escape of processing liquid from the dispensing tray.
  • This invention relates in general to a combined storage receptacle and dispensing device for liquids, and, more particularly, to a container construction and related apparatus for supplying developing liquids and dispensing the same in an electrostatic copying machine or the like.
  • a related object is to eliminate the spillage and inconvenience normally attendant to maintenance of a liquid-type developer of copying machine.
  • a further object is to provide dispensing apparatus for developer solutions and the like, wherein a dispensing tray is automatically filled with the solution as soon as the machine is turned on, is maintained at the proper level while the machine is in operation, and is drained from the dispensing tray as soon as the machine is turned off.
  • Another object is to provide means for maintaining a constant supply of fresh developer fluid in an electrostatic copying machine or the like without requiring the operator to transfer liquid from one receptacle to another by hand, without requiring elaborate disassembly, cleaning, and reassembly steps when the liquid is changed, and without requiring the liquid itself to be transferred directly through a pump from the reservoir to the liquid dispensing tray.
  • Still another object is to provide apparatus for handling liquid developer employed in copying machines or the like, wherein a minimum of time and effort is required to effect a change of the liquid and wherein this operation can be performed with a minimum of skill and withoutthe dangers of spillage and waste.
  • FIG. 1 is a fragmentary top plan view illustrating an apparatus which incorporates the principles of the present invention
  • FIG. 2 is a sectional view taken on the line 2-2 of FIG. 1;
  • FIG. 3 is an enlarged fragmentary section taken on the line 3-3 of FIG. 2;
  • FIG. 4 is an enlarged sectional view taken on the line 4-4 of FIG. I, the device being shown here in operating position;
  • FIG. 5 is a further enlarged sectional view taken on the line 5-5 of FIG. 4;
  • FIG. 6 is a sectional view taken on the line 6-6 of FIG. 5.
  • the invention comprises a receptacle or container generally indicated by the numeral 1, which is in the nature of a bottle.
  • the receptacle is preferably formed integrally of a plastic material such as polyethylene and includes a bottom 3, sidewalls 4 and 5,
  • top wall 8 is provided with a neck portion 9, which may be screw-threaded or otherwise adapted to receive a cap number 11 thereon.
  • the concavity 12 is generally arcuate in cross section, as best shown in FIG. 2, and extends across substantially the entire face of the upper sidewall 4.
  • a plurality of transverse ribs 13 is integrally formed on the upper surface of sidewall 4 to serve as a guide means for copy sheets passing thereover in a manner to be described hereinafter.
  • the container 1 be filled and capped in the nonnal manner and a plurality of containers can be packaged in conventional cartons, with the capped top walls 8 directed upwardly, for delivery to the user. Only a minimum of shipping space is lost by the provision of the concavities 12.
  • a container 1 of fresh liquid developer is laid on its lower sidewall 5 and is inserted through a suitable opening, not shown, in a side or end or the copy machine.
  • Sidewall 5 of the receptacle may be supported directly on the bottom wall 15 of the copy machine and the lower portion including bottom wall 3 is preferably received beneath a supporting flange 16.
  • a lever arm 17 pivotally mounted as at 18 on the supporting flange l6 and having a handle 21 serves to suspend a piercing tube 19 vertically disposed in a central position over the adjacent end of upper sidewall 4.
  • piercing tube 19 is provided with a sharply beveled edge 20 whereby depression of the handle 21 or other control mechanism linked to lever 17 effects a piercing of the top of wall 4 and the lower end portion of tube 19 is inserted therethrough (see FIG. 4).
  • the adjacent edges of wall 4 at the aperture formed by the piercing tube tend to closely surround the tube and form an effective seal along the periphery thereof, as shown at 21a in FIG. 4.
  • the piercing tube 19 has its upper portion bent at right angles in the fonn of an elbow 22 and the outer end thereof is connected to a conventional air pump 23, as by a flexible tube 24.
  • the pump 23 may be of any suitable type having power sufficient to generate a small amount of pressure within the container 1 by communication through the tube 19.
  • a miniature pump of the type normally employed for aerating home aquariums has been sufficient for this purpose.
  • the lower endof tube 19 is provided with ports 25 immediately above its beveled edge 20, and in operating position these parts are disposed closely adjacent the bottom of the dispensing tray formed by concavity 12.
  • a plug member 26 is fixed in the lower portion of tube 19 and is provided with two vertical passages 27 and 28 therethrough. Passage 27 serves to communicate air under pressure from the tube 19 into the container 1, through the opening formed in upper sidewall 4 by the beveled edges 20.
  • a vertical liquid transfer tube 29 is telescopically received in the tube 19, being slidably mounted 'in passage 28.
  • Tube 29 is provided with a cap 30 at the upper end thereof which shuts the upper surface of plug 26to serve as a stop member when the tube 29 is in its extended or operational position, as shown in FIGS. 4 and 5.
  • a light spring 31 extends between the elbow 20 and the cap 30 to yieldably urge tube 29 into its extended position, one end being secured by any suitable means at the elbow and the other end being preferably received in a recess 32 provided on the upper surface of cap 30.
  • a port 33 is provided in the tube 29 for registration with a peripheral groove 34 provided on the plug 26 and communication through port 25 to the dispensing tray provided by concavity 12.
  • a float generally indicated by the numeral 35 is slidably mounted on the tube 19.
  • Float 35 may be formed at expanded polystyrene material or the like and includes an upper portion 36 telescopically mounted on the tube 19 by means of a closely fitting internal bearing sleeve 37 formed of nylon or the like.
  • An annular body portion 38 is suspended below the portion 36 and in spaced surrounding relation with respect to the tube 19, as by an integral depending annular, skirt portion 39.
  • the air pressure generated by pump 23 is delivered directly to the interior of container 1 through the port 27. This pressure forces liquid developer upwardly through tube 29 and through ports 33 and into the bottom of the dispensing tray. As the liquid level in the tray rises, the float 35 is raised until venting ports provided in tube 19 are uncovered to release the air pressure within container 1, and the air is successively vented through appropriate ports 41 provided in the skirt portion 39 of the float.
