Definitions

  • the invention described in this application comprises the use of three distinct parts to make up the single capsule, in which one part may be used to receive one of the materials being used in the finish product, and the second part of the capsule is fastened to this first part in such manner that the first material becomes completely sealed between those first two parts.
  • the remaining material is placed in the third part of the capsule and the third part of the capsule is fastened to the second part, such that the closure between the second part and the first part of the capsule retains the first material separated from the second material in the third part of the capsule, which is normally the larger and mixing portion of the capsule.
  • the invention utilizes a unique stem on the first portion of the capsule, with a constricted neck on the second portion which is plugged by the stem on the first portion to make the sealed container, asheretofore described.
  • This invention relates generally to dental materials and the like and more particularly to a method and apparatus for packaging and preparing the same.
  • Most devices and methods used involve a two part capsule or container with a valving action of some sort to dispense one material into contact with another.

  • a preferred embodiment of the container used in this invention comprises three basic parts 210, 230 and 250.
  • a bottom section 210 comprising an elongated container 213 open at one end and essentially concave-convex on its closed end 212 with a suitable knurled flange or the like 211 adjacent its closed end.
  • the lower section has a threaded portion 214 adjacent the open end. It will be observed that a suitable shoulder 215 is provided for sealing against the adjacent portion as will be clear from the drawing and as is hereinafter described.
  • the intermediate section 230 consists of an elongated cylindrical portion having both its ends open and having a restricted portion 235 between the ends with concave shape towards the restricted portion. It will be observed that one end has threads 231 suitable to engage the threads 214 on the lower portion herebefore described, and it has suitable matching configurations at 232 so that the shoulder 215 of the lower portion as before mentioned will seal directly therein to make a tight seal to prevent materials from leaking out.
  • a knurled portion 236 is provided for easy handling.
  • the top portion 250 consists of an essentially cup shaped portion, the open end of which is provided with threads suitable to engage threads 233 of the intermediate portion and with suitable configuration to engage the configuration of the upper portion of the intermediate portion to effect a tight seal with portion 235 as is clear from the drawing.
  • the upper portion also has a stem 253 depending towards its open end from the center of the closed end, which stem is configured so as to form a seal as indicated in the drawing. at 234 against the restricted portionof the intermediate section.
  • the material in the upper cup shaped portion of the capsule shown in FIGURE 6 may be silica powder with a resin reactive agent 300 and the material in the lower portion of the same capsule may be a resin liquid 310 for use in silicate dental fillings.
  • a mixing pestle 320 there may be added as desired a mixing pestle 320 so that when the container is shaken vigorously, as is usually the case for mixing such materials, the materials will be pounded together by the action of the pestle.
  • a mechanism comprising a frame with a pair of roller chains 70 and 71 having blocks 90 of suitable material 91 such as Masonite or the like suspended between them as indicated may be used. It will be noted that there are sprocket units and suitably mounted for moving the chain and at Geneva motion or the like with drive chain and gears 60 for indexing so that the chains 70 and 71 may be stopped at various places as desired. Power may be imparted by hand wheel 41 or a motor.
  • FIG- URE 7 a typical holding hole 97 in one of the Masonite blocks 90, which holding hole has three basic dimensions 97a, 97b and 970. It will be observed in all of the FIG- URES 7, 8 and 9 and 10 that this same hole numbering system has been followed and that the hole 97a is of sufficient diameter that the portion of the capsule or container 2'50 rests within that part of the hole and is shown there.
  • the knurled portion 211 rests within the cavity 97a and the end clears in the portion 97b.
  • amalgam fillings For dental materials the most common materials in present use are silver amalgam fillings and silica fillings. The identical situation illustrated herein may be used for either the amalgam or the silica fillings and, of course, is applicable to many other materials of similar nature which 'must be kept separated prior to use at which time they react with one another.
  • silicate material has been placed into the portion 250 of the capsule while the liquid used with this has been placed into the portion 210.
  • mercury will normally be used in the place where the silicate powder is indicated and the silver powder or pellets will be in the place where the silicate liquid is indicated. Basically, the reason for this transference is that it is generally easier to move the mercury from the top portion into the bottomportion for mixing with the silver when the amalgam is used and generally it is easier to move the powder from that portion into the larger chamber when the silicate system is used.
  • a filling device In filling the materials into the various portions of the containers, a filling device is extremely important and I have discovered that the filling device indicated generally by the reference numeral and in detail in FIGURES 11, 12, 13 and 14 is most desirable and unique for certain of these materials.
  • mercury is notoriously diflicult to feed in controlled quantities and there are available commercial devices of some complexity for achieving this. I have, however, devised a new and improved and unique feeding system for mercury, which feeding system is also applicable to powder and other items. being fed in this overall filling method.
  • top container portions 250 are placed in the holes 92, 93, 94, 95, 96 and 97 in the blocks 90.
  • the blocks are caused to advance a fixed distance through the Geneva mechanism. This fixed distance is the distance between the center lines of the'holes on one block to the next block.
  • the alignment point is at the point where the holes in the block are immediately under the holes in the filling mechanism.
  • the container portion may be placed in the blocks by hand or a bowl feeder as is well known in the art may be employed.
  • the handle 140 is moved to carry the material to be fed into the container portion.
  • the handle 140 is then removed to its original position where the holes in the Teflon strip may once again be filled with the material contained in the trough.
  • the intermediate portion 230 is placed into the part 250 and. screwed together by hand or by power screwdriver, as are well known in the art and as indicated in FIGURE 8.
  • a tight seal has been caused between the parts, both at the shoulder between the two parts and at the place where the stem meets the restricted portion of the intermediate section. This seal as effected is clearly illustrated in FIG- URE 6.
  • top portion 250 joined through the intermediate portion 230 is removed from the block 90 and can be stored until used in the remaining part of the filling operation as will be described below.
  • Teflon strip it may be necessary to substitute a Teflon strip for the original Teflon strip used in the filling device 100, but the only reason for doing this will be to provide a different quantity when it is desired to provide a different quantity of the material next used.
  • the manner in which the quantity being dispensed is changed is by having a different strip with a different sized set of holes 160, 162, 163, 164, 165 and 166. Obviously, by altering the size of the hole in this Teflon strip or by altering the thickness of the Teflon strip the amount of material may be altered.
  • the lower portion of the container as specifically indicated at FIGURE '9 is fed by hand or by bowl feeders into the holes in the carrying blocks 96.
  • the material being used will be dropped into this portion 210 of the container.
  • the pestles 320 may be then placed by a customary bowl feeder, or by hand.
  • top and intermediate sections will be placed upon the upstanding end of portion 210 and screwed on as indicated in FIG- URE 10. This may be accomplished by hand or by power screwdrivers as is well known in the art.
  • the entire unit may be removed and shipped, stored or used as the case may be.
  • a silicate dental filling material may be prepackaged in proper proportions for use by feeding the top portion of the container illustrated in FIGURE 6 with silicate powder through the feeding device indicated and assembling the intermediate portion of the capsule indicated in FIGURE 6 as specifically heretofore described and sealing the same so that there may be accumulated a supply of portions of the container with the silicate powder sealed so that it cannot escape from the top.
  • liquid material used with the silicate powder together with a mixing pestle may be placed in the lower portion as will be clear from the drawings, after which the stockpiled top portions with the intermediate portions may be screwed on to the lower portions to effect the complete unit.
  • a mercury silver amalgam material for dental fillings may be used in the same manner, but in this case it is deemed desirable to place the mercury in the top portion of the capsule in the place where the silicate powder 300 is indicated in FIGURE 6 of the drawings. This is accomplished by filling the mercury through the unique feeders I have described and then combining it with the intermediate portion as shown in FIGURE 8. At this point because of the very effective seal accomplished no mercury will be spilled even though this portion of the capsule is stock-piled and the handled.
  • silver powder or pellets may be placed in the place of the liquid 310 shown in FIGURE 6 and in the operation shown more specifically in FIGURE 9.
  • the pestle 320' may also be added and thereafter the entire unit assembled as indicated in FIGURE 10
  • Medical products may also be used in this identical manner; for example, a water mixed medication which is normally preserved in powder or crystalline form without special treatment, but which will deteriorate rapidly after mixing with water, may be placed in its powder or crystalline form in the upper portion of the container in the place where the silicate powder 300 is indicated in FIGURE 6. Utilizing the same filling system as heretofore described, and which will not be repeated, this is sealed off with the intermediate portion and thereafter distilled water or other liquid or other mixing agents may be placed in the lower portion 213 as indicated in FIGURE 6. When the entire unit is assembled as heretofore described this item may be kept ready for use without danger of deterioration.
  • the top portion is once again tightened onto the intermediate portion and the stem once again seals so that on mixing all materials will be retained within the basic cavity 213.
  • the container may be placed in a mechanical device such as an amalgamator or the like in the case of dental materials.
  • Amalgamators are customarily used in dental offices for mixing materials and consist of a device to shake a container very rapidly.
  • the intermediate section is gripped at its knurled portion 236 and the lower portion is gripped at its knurled portion 211 and the two are completely separated.
  • the mixed materials may then be removed from the lower portion 210 and all portions of the container may be disposed of if desired.
  • a container for handling materials which must be kept separated until used comprising a first portion open at one end and closed at the other end and having a cavity intermediate the ends, a second portion detachably attached to the said first portion having both ends open and defining a passageway between the ends with 'a constriction in said passageway inter-mediate its ends; a third portion detachably attached to the said second portion having one end open and one end closed and having a cavity between the ends, said third portion having attached thereto means for temporarily closing the restriction between the ends of the second portion.
  • a container for handling materials which must be kept separated until used comprising: a first generally cylindrical portion open at one end and closed at its other end, having threads around its outer circumference adjacent said open end and having its closed end in a generally concave shape, and having an enlarged knurled portion around its outer circumference intermediate the ends; a second cylindrical portion having both its ends open and having threads adjacent each of its ends and having a constricted opening through its axis intermediate its ends, said second portion being attached by mean of said threads to the threads on saidfirst portion; and a third cylindrical portion being opened at one of its ends and closed at its other end and having its closed end in a generally concave shape with a stem depending from its closed end towards its open end, said stem being so designed as to seal the. constricted opening in said second portion, threads adjacent said open end, said threads being fastened upon threads of said second portion.
  • Acontainer for materials comprising: a first cylindrical portion being open at both ends and having an opening through its length, said opening at some position intermediate its ends bein somewhat constricted, and having threads adjacent each of its ends, and having an enlarged portion vof its outer circumference intermediate said ends and intermediate said threads; a second cylindrical portion having one of its ends closed in a concave shape and defining an open end container with threads adjacent the open end, said threads being detachably attached to one set of threads in the said first portion, said second portion having a well defined shoultion, the said third portion being detachably attached by threads adjacent its open end to the second set of threads on said first portion, said second portion and third portion having a shoulder arrangement which matches and forms a seal on the interior of the said third portion and said third portion having an enlarged area intermediate its ends on the outer circumference thereof.
  • connection be tween the first and second portions comprises male tl reads on said first portion cooperating with female threads on said second portion
  • connection between the second and third portions comprises male threads on the said second portion cooperating with female threads on the said third portion.
