Definitions

  • the present invention relates to a double tube dispenser of the above-mentioned type in which the said disadvantage has been remedied, and which consists of a rigid tube member and ahousing member, the tube member consisting of two juxtaposed cylindrictubes' of substantially equal wallthickness united along'a common generatrix, said tubes being open at one end andclosed at the opposite end by a wall integral with a substantially cylindric nozzle portion, the axis of which is central between the axes of the two tubes, said nozzle portion having channels leading to the interior part of each tube, and the housing member comprising two part-cylindric walls united to form a tubular body, and a base plate closing said tubular body at one end and carrying two shafts protruding in coaxial'position into the tubes and carrying at their ends pistons fitting therein.
  • the tube body By giving the tube body the shape of two completely or almost completely cylindrical tubes which atmost are connected at a narrow joint surface alonga generatrix of each, it is possible to manufacture the tube body from plastic without the risk that thebody deforms unduly during the hardening of the plastic or during the cooling after the hardening; consequently the cylinder surfaces of the tube body are able to slide close to the cylinder surfaces of the housing member.
  • T his latter may also be of plastic, and still have no tendency to di'stort'during the hardening and the subsequent cooling, as the walls of the said tube case have practically equal thickness throughout.
  • the tube compartments may be filled, the dispensing container has been assembled, the filling being made through cannulae to the channels of the dispensing nozzle.
  • the dispensing container After the filling the dispensing container will be in its expanded position with the connection portion EJ652231 Fatented Jan. 19, 1965 ice of the tube member engaging the intruding portion of the housing member, and with the pistons being at open ends of the tubes of the tube'rnember.
  • the tube member is pushed slowly down into the housing member a quantity of the contents of thetubes of the tube membercorresponding to the quantity filled into the tubes will be pressed out in the shape of two closely juxtaposed bands.
  • a convenient method for assembling the dispensing container enabling the. two tube compartments to be filled through the open ends of the tubes of the tube member mayaccording to the present invention consist in the dispensing nozzle having notches on a level with surfaces which continue the cylinder surface of the housing member facing each other; the bottom of the housing member may consequently be one separate piece which is not mounted on the cylindrical part of the housing member until the tubes ofthe tube member have been filled, and the said member drawn out with'its connection portion engaging the intruding portion at the other end of the housing member.
  • the pistons In connection with the mounting of the said bottom the pistons, too, are mounted in the tubes of the tube body.
  • the tube member and the housing may therefore be manufactured from two different plastics, chosen with a view to causing a minimum of friction. According to the present invention it is particularly convenient if the tube member'is manufactured from low pressure polyethylene, and the housing member from impact proof polystyrene.
  • FIG; 1 shows the dispensing container without a covering cap, in perspective, in its extended position
  • FIG. 2 shows the tube member in side elevation
  • FIG. 3 shows the tube member seen from above
  • FIG. 4 shows a section of the tubemember on the line
  • FIG. 5 shows a section of the tube member on the line V-V of FIG. 2;
  • FIG. 6 shows the housing member in a sectional view through the longest symmetry plane
  • FIG. 7 shows a section of the housing member on the line VII--V1I of FIG. 6;
  • FIG. 8 shows a section of the housing member on the line VIIIV1II of FIG. 6;
  • FIG. 9 in side elevation and part section, shows the separate bottom with pistons for the tubes
  • FIG. 10 shows the bottom seen from above in a horizontal sectional view through the piston rods.
  • 1 is a tube member, and 2 a housing member.
  • the tube member (FIGS. 2-5) is shaped as two juxtaposed tubes 3 and 4, the axes of which are parallel, and which in the embodiment shown 'are mutually connected at a narrow strip 5 along a common generatrix.
  • the said tubes are provided with cylindrical tube compartments 6 and 7 which are open at the bottom but at the top are closed by a plane wall 8 which carries a cylindrical dispensing nozzle 9, common toboth tubes, with a thread 10 for the screwing on of a tube cap, not shown in the figure.
  • the dispensing nozzle 9 is provided with channels 11 which leads each to its own of the two tube compartments 6 and 7.
  • connection portion 14 which partly fills the space between those sections of the cylindrical external walls of the tubes 3 and 4 which face each other but is of slight extension in the axial direction.
  • the housing member 2 is made of a material which is substantially of the same thickness throughout the length of the housing member, as shown in FIG. 8, and consists of two part cylinder surfaces 12 and 13 which are mutually connected with more or less plane partitions 15 parallel with the symmetry plane 16 of the tube case, and at such a distance from the said symmetry plane that the connection portion 14 of the tube member may pass freely within the said partitions.
  • the housing member is provided with internal intruding portions 17 which fit into the angle between the tubes of the body member.
  • the dispensing nozzle is provided with notches 18 cut at opposite angles into the surface of the said nozzle which notches form a continuation of the cylinder surfaces of the tubes facing each other, and through which the intruding portions 17 may pass when the tube member is inserted into the housing member from the bottom of the latter, and is pushed so much forward that the dispensing nozzle will project from the uppermost edge of the housing member.
  • FIGS. 9 and 10 depict a bottom 19 with piston rods 20 and pistons 21.
  • Double-tube dispensing container consisting of a rigid tube member and a housing member, the tube member consisting of two juxtaposed cylindric tubes having parallel axes, the distance between the axes being greater than the sum of the radii of the said tubes, said tubes being open at one end and closed at the opposite end by a wall integral with a substantially cylindric nozzle portion, the axis of which is central between the axes of the two tubes, said nozzle portion having channels leading into the interior part of each tube, and the housing member comprising two part-cylindric walls united to form a tubular body and a base plate closing said tubular body at said one end and carrying two shafts protruding in coaxial position into the tubes and carrying at their ends pistons fitting therein.
  • Double-tube dispensing container according to claim 1 in which the tube member and housing member are of different synthetic materials so chosen as to give minimum friction.
  • Double-tube dispensing container according to claim 2 in which the tube body is of low-pressure polyethylene and the housing member is of impact-resisting polystyrene.
  • Double-tube dispensing container consisting of a rigid internal tube member and a housing member the tube member consisting of two closely juxtaposed cylindric tubes of substantially equal wall thickness having parallel axes, the distance between the axes being greater than the sum of the radii of the said tubes, said tubes being open at one end and closed at the opposite end by a wall integral with a substantially cylindric nozzle portion, the axis of which is central between the axes of the two tubes, said nozzle portion having channels leading into the interior part of each tube, and the housing member comprising two part-cylindric walls united to form a tubular body and a base plate closing said tubular body at one end and carrying two shafts protruding in coaxial position into the tubes, each tube carrying at its end a piston fitting into a tube, each tube having adjacent to its open end a connection portion, extending only a short distance from the end, and the housing having at its open end an intruding portion, which likewise has only a slight extension in axial direction
