Definitions

  • caulking guns for providing sealant beads in building construction and the like.
  • Such guns are adapted to use disposable tubular cartridges which contain the caulking compound or sealing material.
  • a piston operated by a gun applies pressure to a rear portion of the cartridge, forcing the caulking compound out of the nozzle at the front of the cartridge.
  • caulking compounds or sealing materials are known for various specific applications and can be packaged in cartridges such as those mentioned above.
  • sealant compounds designed for caulking use which compounds remain in freely flowable form until exposure to water vapor in the air. The water vapor reacts with the compound to form a rigid or semirigid sealing material.
  • the present invention a construction in which the improvement resides in (l) forming a tighter seal against water vapor between the plunger and interior of the tubular cartridge body, and (2) to dry, insofar as possible, any air which reaches the vicinity of the plunger.
  • the problems inherent in the prior art are solved very simply by providing a coating of silicone oil between the plunger and the Wall of the tubular member and by providing a quantity of drying agent, or desiccant, immediately adjacent the plunger by enclosure of the desiccant with the cartridge end cap.
  • the resulting construction is simple to manufacture, extremely efiicient and solves the problems inherent in the prior art.
  • a plunger 4 Disposed within the tubular member 1 at the end opposite the nozzle end is a plunger 4 having a generally cylindrical surface conforming to the interior of the tubular member 1.
  • a quantity of caulking compound 5 fills the space between the plunger 4 and the nozzle seal 3.
  • the plunger Upon application of pressure to the plunger in a direction toward the nozzle, the plunger is designed to slide toward the nozzle, forcing the caulking compound 4 out through the nozzle 2.
  • the plunger 4 is coated with a silicone oil, preferably having a viscosity between and 1000 centistokes. Such coating can be applied by dipping the plunger 4 into the silicone oil prior to insertion into the tubular member 1.
  • the object of coating the plunger with the silicone oil is to provide a silicone oil film between the plunger and the inside surface of the tubular member '1. It is, therefore,
  • a quantity of drying agent such as calcium chloride, is introduced behind the plunger, and a cap 6 is slideably fitted over the open end of the tubular member 1 to enclose the drying agent between the cap and plunger 4.
  • alumina Mg(ClO and Ba(ClO are useful in this application.
  • desiccants can absorb water from air by either adsorption, absorption or both.
  • suitable desiccants are, of course, those which would react chemically with the end cap, the tubular member or the plunger to cause deterioration. For this reason the construction materials must be considered in the choice of drying agent in any given application.
  • a caulking cartridge comprising a tubular body adapted for insertion in a caulking gun, a nozzle for ejection of caulking compound mounted at one end of said body, and a slideable plunger adapted upon application of pressure for sliding from an initial position at one end of said tubular body to the nozzle end substantially in contact with the inner surface of said tubular body to eject said caulking compound from said body, the improvement which comprises:
