Definitions

  • This invention relates to the improvements and/or modifications in muIti-chamber devices for packaging of predosed substances.
  • the first of my aforesaid prior applications discloses a cartridge-like device comprising two chambers or compartments or the like separated from one another by a releasable partition in the form of a disc or flat object clamped resiliently between the walls of the device and adapted to be expelled into one-of the chambers by means of a pusher or plunger or the like sliding in the opposite end of the other chamber, the partition serving after its expulsion as an agitator to grind the mix of substances by agitation.
  • a ball is used as the partition member.
  • Devices of this kind are of use more particularly when, to ensure an intimate and homogeneous mixing of the ingredients, the mixing is performed by means of a weight whichg'rinds the mixture when the cartridgelike device is shaken inconventional agitators. This occurs inter alia with dental amalgams.
  • FIGS. 1, 2 and 3 are elevational views in crosssection along the lines I-I of FIG. 4, and
  • FIG. 4 is a view in cross-section on the line lV-IV of FIG. 3.
  • the cartridge-like device is embodied, in just the same way as in the aforesaid parent applications, by a casing of plastic material comprising two members 1, 7 which engage telescopically with one another and which bound two chambers or cavities or compartments or the like l0, 11 respectively each receiving one of two substances to be mixed together, namely a powder 12 and a liquid 13.
  • a plunger or pusher or the like 3 can slide in member l and can act in the internal cylindrical part of member 1.
  • the partition is moved by the plunger as it produces a hydrostatic force on liqclosed in the first of my aforesaid applications, or in able for some mixtures, including mixtures of two substances to be used in the preparation of dental cements such as the conventional products which are prepared by mixing a metal oxide base powder with an acid Iiq- A separates from one another in two chambers containing the substances to be mixed, and a final or mixing position, in which the partition cooperates with the pusher to close the chamber in which mixing is carried out.
  • the wall of the device has, in a zone intermediate the two chambers corresponding to movement of the partition between its two positions, one or more passages in permanent communication with the mixing chamber, the passage or passages providing communi' cation between the two chambers when the partition is moved by the pusher to a position where the contents of one chamber is to be placed into the mixing chamber and the contents are to be mixed and being closed at other times.
  • the moving partition completes the contourof the mixing chamber while the pusher closes the passages between the two chambers and engages with the rear surface of the partition.
  • the partition 2 can remain in a stable position just by friction or, if forcefitted, by the resilience of the plastic used to make it or the housing.
  • the lower cylindrical part of member 1 extends until it telescopes over the lower part7 to form a space for the chamber lll.
  • upper part 1 has an edge 6 serving as an abutment and as a stop for the partition 2 when the same has moved into its final position shown in FIG. 3 as a result of the plunger 3 having been pushed all the way home.
  • the inner wall of member 1 is formed at the bottom of chamber 10 with passages 4.
  • Two passages 4 are provided in the present case but their number and distribution can vary as appropriate.
  • the passages 4 extend from the bottom surface of partition 2, when the same is in its chamber-separating position shown in FIG. 1, to the chamber 11 into which the passages 4 open without restriction.
  • partition member 2 Since partition member 2 is above the passages d (FIG. 1), it closes the chamber 10 hermetically so that no liquid 13 can leak to the product 12 in the other chamber.
  • the plunger 3 is pushed in.
  • the partition 2 is part-way along the length of the passages 41 clearing the openings to the passages in the top chamber 10, so that the two chambers 10, ll communicate with one another and the liquid 13 descends into the chamber 11, as indicated by arrows, and mixes with the product 12.
  • a container for the packaging and mixing of predetermined amounts of materials comprising a housing formed by first and second interconnectable sections, said second section having a closed lower end, a movable partition member located in one of said sections of said housing, said partition member when in a first position dividing the interior of said housing into first and second chambers each for holding a respective first and second material which are to be admixed, said second chamber being formed at least in part by said second housing section including its closed lower end, the internal volume of the second chamber being sufficiently great to accommodate the materials in both said chambers, a plunger accessible from outside of said housing having a portion extending through said housing for moving within said first chamber from a first position to a second position to move said partition member within said housing in a corresponding manner from its first position in which the partition member separates the two chambers to a second position, means on the interior of said housing in the zone between the first and second positions of said partition member forming a passage for transfer of the material in said first chamber to said second chamber as the material in said first chamber
  • a container as in claim 1 wherein said means on the interior wall of the housing for engaging and holding the partition means comprises a projection on said housing.
  • a container according to claim 1 wherein the passage forming means between the two chambers comprises at least one recess formed on the inner wall of the housing starting at a point adjacent the point of rest of the partition member at its first position.
  • a container according to claim 1 wherein said partition member is disc shaped.
