  • Patent number: 4941594
    Abstract: The present invention is a dispensing-tube and cap holder for use in combination with an aerosol can and a dispensing-tube. The aerosol can includes a cylindrical container which has an annular sidewall, a top peripheral rim and a bottom peripheral rim, a valve and a cap. The valve is fluidly coupled to the cylindrical container. The cap covers the valve when the aerosol can is not in use. The dispensing-tube may be fluidly coupled to the valve. The dispensing-tube and cap holder includes a curved, rectangular sheet having a front surface, a rear surface, a top edge, a bottom edge and two side edges. The length of the two side edges is slightly shorter than the length of the cylindrical container. The dispensing-tube and cap holder also includes a sheath, a tube-tensioning mechanism and a cap-holding mechanism. The sheath is disposed on one of two sides of the curved, rectangular sheet and holds the dispensing-tube.

  • Patent number: 4542863
    Abstract: An improved reel for dispensing threaded-pipe sealing tape is disclosed, wherein a tape retarding element is provided and mounted for circular movement about the periphery of the reel. The tape retarding element is mounted between the side flanges of the reel so that an applied force must be tangentially directed thereto to overcome the friction between the tape retarding element and the side flange portions between which the tape retarding element is mounted. The tape retarding element allows for the paying out of the tape for its wrapping about the threaded end of a pipe, but prevents the accidental unwinding of the tape upon the dropping of the reel from a user's hand.
