Definitions

  • Caulkers that are widely used as dispensing containers for sealants, adhesives, and caulking compounds have not been available for two component materials such as epoxies that require separate storage of highly viscous materials and mixing these materials together immediately before use.
  • the two component dispensers that exist for liquids, pastry decoration, and other light duty purposes are not suitable for highly viscous, resinous materials presently used in two component adhesives and sealants.
  • My inventive caulker dispenses two viscous components contained in two separate, molded resin chambers.
  • a generally cylindrical outer chamber contains a collapsible inner chamber having accordion pleats that fold in a predetermined accordion collapse when compressed.
  • the inner chamber has a rear end filling opening, and a molded resin plunger is secured to the rear end of the inner chamber and shaped to fit closely within the outer chamber.
  • the forward regions of both chambers are joined, and passageways from each chamber merge at the forward end
  • An openable barrier seals the forward end of the inner chamber, and a removable closure element .seals the forward end of the outer chamber.
  • a static mixer and nozzle are attached to the forward end of the outer chamber in communication with the passageways after the barrier seal is opened and the closure element is removed. The plunger then advances within the outer chamber while collapsing the inner chamber to force both components from their chambers through the passageways, static mixer, and nozzle.
  • My illustrated preferred embodiment uses an accordion-pleated, collapsible inner chamber 11 arranged within a generally cylindrical outer chamber 12 in which a plunger 13 is fitted.
  • One component 14 is stored in outer chamber 12 around inner chamber 11, and the other component 15 is stored within inner chamber 11.
  • Advancing plunger 13 then collapses inner chamber 11 to force component 15 forward and also presses component 14 forward with a piston action so that both components are expelled at the forward end of the caulker.
  • the preferred way to accomplish this is explained below relative to FIGS. 3 and 4.
  • Outer chamber 12 is generally cylindrical and molded of resin material in dimensions that preferably fit existing caulking guns and dispensing equipment so that caulker 10 can be used just like existing caulkers. Forming caulker 10 of plastic materials also keeps the cost low, protects both the stored components, and takes advantage of known technology in the caulker art.
  • Inner chamber 11 is also molded of resin material with preformed accordion pleats 16 shaped to fold in a predetermined accordion collapse when inner chamber 11 is axially compressed.
  • Chamber 11 is preferably arranged concentrically within chamber 12 as illustrated, but can also be axially offset, have a shape other than cylindrical, and even be divided to hold more than one component.
  • Its rear end has a filling opening 17 and external screw threads 18 that mate with a threaded socket 19 on plunger 13. This allows collapsible chamber 11 to be filled with component 15 via rear opening 17, which is then closed by screwing socket 19 of plunger 13 over threads 18.
  • Plunger 13 thus serves both as a closure cap and mounting support for inner chamber 11 and as a piston dispenser sliding within outer chamber 12.
  • Inner chamber 11 also has an external thread 20 formed on its forward end for screwing into a socket 21 formed in the forward end of outer chamber 12 as best shown in FIGS. 3 and 4. This anchors inner chamber 11 securely relative to the forward end of outer chamber 12.
  • An openable barrier 22 closes the forward end of inner chamber 11, and barrier 22 is removable around a line of weakness 23 to open inner chamber 11 for dispensing. Foil seals secured in place and molded tips that can be cut away are alternative possibilities for sealing the forward end of chamber 11.
  • outer chamber 12 has an external screw thread 25 on a neck 27 on which closure cap 26 is screwed to seal the forward end of caulker 10 before use.
  • Radial spacer fins 28 support threaded socket 21 within neck 27 and also form a passageway 29 for component 14.
  • Closure cap 26 is shaped to fit snugly against the forward surfaces of neck 27 and socket 21 to close off and seal passageway 29. Cap 26 also preferably fits snugly against the forward end of inner chamber 11 so that both components are securely sealed in place before use.
  • Caulker 10 also includes a dispenser nozzle 30 with a static mixer 31 in a dispensing passageway forming an output from caulker 10.
  • Nozzle 30 screws onto thread 25 in place of cap 26.
  • passageway 29 for component 14 is opened up; and when barrier 22 is removed, the forward end of chamber 11 forms an open passageway for component 15.
  • components 14 and 15 are forced forward by plunger 13 to merge within nozzle 30 and mix together as they are forced through static mixer 31 and dispensed from caulker 10.
  • nozzle 30 can be unscrewed and replaced with cap 26, which is preferably shaped to seat and seal both the inner and outer chambers to protect both components. Cap 26 can bear against several surfaces of each chamber for this purpose.
  • a foil seal adhered to the forward end of outer chamber 12 can be substituted for screw cap 26, especially for caulkers intended for the building trades, with their dispensing equipment and relatively rapid consumption.
  • Chamber 11 can be filled either before or after it is screwed into chamber 12, and plunger 13 doubles as a cap for chamber 11.
  • Chamber 12 is preferably filled from the front after chamber 11 is in place, and chambers 11 and 12 can be properly dimensioned to dispense components 14 and 15 in the right proportions.
  • FIGS 5-7 show several other alternatives for practicing the invention.
  • a pouch 40 can be arranged within inner chamber 11 to hold component 15.
  • Pouch 40 can be formed in generally known ways of foil, resin, or foil and resin laminates that can securely seal in component 15.
  • Using a pouch 40 within inner chamber 11 also allows caulker 10 to serve as a three-component dispenser because one component can be placed within pouch 40, the remainder of inner chamber 11 can be filled with another component around pouch 40, and a third component can be filled into outer chamber 12 around inner chamber 11.
  • chamber cap 41 can be used without vent holes 42 for closing the rear end of chamber 11 when it is directly filled with component 15 or filled with a third component surrounding pouch 40.
  • Pouch 40 has to be punctured or torn near its forward end before dispensing begins, and a preferred way of accommodating this is shown in FIG. 5.
  • Barrier 22 for inner chamber 11 is formed as a rounded tip that can be cut off to open a dispensing passageway 43 from inner chamber 11. Then a puncturing tool such as a nail or awl can be inserted through passage 43 and into pouch 40 to puncture the forward end of pouch 40 and allow its contents to escape through passageway 43 as chamber 11 collapses.
  • FIG. 6 Another way of puncturing pouch 40 as shown in FIG. 6 is with a needle 45 that is pushed into dispenser passageway 43 to puncture bag 40 before nozzle 30 is screwed in place.
  • pouch 40 can be made large enough to hold a volume equal to the full volume of chamber 11 and extend rearwardly of chamber 11 before use. Outer chamber 12 is preferably extended rearwardly as illustrated in FIG. 7 to accommodate a longer pouch 40 for this purpose. Pouch 40 can then be opened and emptied into chamber 11 just before dispensing begins, and chamber 11 can be closed with an unvented chamber cap 41. Nozzle 30 and cap 41 can be stored in the space around pouch 40 provided by elongating outer chamber 12 so that all necessary components are available in a single package.
