Definitions

  • a package of thin abrasive disks comprising a stack of disks in a moisture impervious container.
  • the container comprises a cylindrical tube with a bottom enclosing one end of the tube and a removable top fitting tightly over the opposite end of the tube.
  • This invention relates to packaging and, more particularly, to a package of thin abrasive disks.
  • abrasive disk that is in common usage has a paper or cloth backing and abrasive particles or grit covering the face of the disk.
  • the abrasive particles are bonded to the backing by means of a resin which is applied in the form of a coating over the entire face of the disk.
  • abrasive disks mount on a fiat, rotary face plate which forms a rigid backing for the disk.
  • the disk is thin and flexible and therefore requires the support of the face plate in order to apply the necessary grinding pressure against the workpiece.
  • the abrasive disk usually has a hole at the center to fit over a mounting stud and is clamped against the face plate by a washer at the center of the rotary face plate.
  • the disk usually is not secured in any manner around the periphery of the face plate and therefore it is necessary for the disk to have a slight curvature which is concave on the backing side of the disk.
  • the concave shape of the abrasive disk causes the peripheral edge of the disk to be urged against the face plate around the rim where the center of the disk is clamped against the face plate by means of a conventional nut and washer. When the face plate and disk are rotated, the peripheral edge of the abrasive disk tends to remain pressed against the face plate.
  • an abrasive disk package in the form of a cylindrical tube with a bottom enclosing one end of the tube and a removable top fitting tightly over the opposite end of the tube.
  • the side wall of the tube has an inner lamina of heavy paper or cardboard, with an intermediate lamina of moisture impervious sheet material, such as aluminum foil, and the other lamina is formed of heavy paper or cardboard.
  • the internal diameter of the tube is slightly larger than the outer diameter of the abrasive disks and the disks are stacked in the tube between the bottom and the top.
  • FIG. 1 is a side elevational view, partially in cross section, of the package of this invention.
  • FIG. 2 is an enlarged detail view of a portion of the package.
  • FIGS. 1 and 2 A package 2 of abrasive disks in accordance with this invention is illustrated in FIGS. 1 and 2.
  • the package 2 includes a cylindrical tube 4.
  • the tube 4 has a bottom 6 in the form of a rigid circular plate that is impervious and preferably formed of metal.
  • a rim 8 is formed on the bottom 6 and the rim has a channel 10 for receiving one end of the tube 4. The opposite sides of the rim 8 are crimped toward each other to secure the tube in the channel 10.
  • a plurality of abrasive disks 12 are supported on the bottom 6 of the package.
  • the disks 12 have a paper or fabric backing and have one face covered with a layer of abrasive grit which is bonded to the backing by a resin coating.
  • the abrasive disks 12 are slightly spherical, and the lowermost disk engages the bottom 6 along the peripheral edge of the disk, while the center of the disk is spaced above the bottom 6. All of the disks have substantially the same shape, so that there is no tendency for the disk to become flattened by the weight of other disks piled on top of it.
  • the internal diameter of the tube 4 is slightly larger than the diameter of the disks to provide sufiicient clearance for removal of the disks from the package, but the tube has a sufiiciently small diameter to restrict lateral displacement of the disks.
  • the tube 4 is laminated of metal foil 14 which is sandwiched between an interior layer 16 and an exterior layer 18 of fibrous material, such as heavy paper or cardboard.
  • the tube is spiral wound with an interior layer 16 of jute paper of the order of .022 inch thickness, a layer of aluminum foil of .0035 inch thickness and the exterior layer 18 of 30 pound weight heavy kraft paper.
  • the metal foil 14 acts as a moisture barrier to prevent the entry of moisture into the interior of the package, while the interior layer of paper protects the metal foil from abrasion by the disks 12. Otherwise, the abrasive grit on the disks would quickly wear through the metal foil and destroy its effectiveness.
  • the peripheral edges of the disks 12 fit closely adjacent the interior surface of the paper layer 16, there is space for slight lateral movement of the disks against the paper, but the interior laminate is sufficiently thick to prevent the abrasive disk from wearing through the paper and the metal foil.
  • the top of the package is closed by a lid 20, which is preferably formed of metal.
  • the lid 20 has a recessed rim 22 and the edge 24 of the lid 20 is flared outwardly to facilitate pressing the lid over the end of the tube 4.
  • a sheet of heavy paper may be placed on the uppermost disk to protect the lid from the abrasive grain and also to act as a filler.
  • the lid 20 fits tightly around the tube 4 to prevent the entry of moisture between the lid and the tube.
  • the lid may be secured to the tube by a tape (not shown) extending around the edge 24 and bonded to the lid and the tube. The tape is removed when the package is opened for the first time.
  • the recessed rim 22 of the lid 20 is adapted to receive the rim 8 of the bottom 6 of another package, so that the packages may be easily stacked one on top of the other.
  • the cooperation of the lid 20 and the bottom 6 causes the packages to be centered and resists accidental displacement of a stack of packages 2.
  • the abrasive package of this invention protects the abrasive disks 12 from moisture and physical damage. Consequently, the disks retain their desired shape.
  • the lid 20 is easily removed and the disks may be withdrawn one at a time, as needed. The package then may be resealed merely by replacing the lid 20.
  • the packages themselves may be easily stacked on top of each other because the depressed rim 22 on the lid 20 allows the bottom of another container to rest on the center portion of the lid 20 with the rim 8 directly above the rim 22.
  • a package of abrasive disks comprising a plurality of disks each having a backing on one side of the disk and having abrasive grit bonded to the other face of said disk, said disks being stacked in substantially axial align ment, a cylindrical tube extending around the circumference of said disks, a bottom closing one end of said tube, and a lid closing the opposite end of said tube, said bottom and lid and tube being impervious to moisture.
  • a package of abrasive disks comprising a plurality of disks each having a backing on one side of the disk and having abrasive grit bonded to the other face of said disk, said disks being stacked in substantially axial alignment, a cylindrical tube extending around the circumference of said disks, a bottom closing one end of said tube, said disks being of substantially uniform thickness and being concave on the backing side, said disks having the backing side facing said bottom, and a lid closing the opposite end of said tube, said bottom and lid and tube being impervious to moisture.

  • a package of abrasive disks comprising a plurality of disks each having a backing on one side of the disk and having abrasive grit bonded to the other face of said disk, said disks being stacked in substantially axial alignment, a cylindrical tube extending around the circumference of said disks, a bottom closing one end of said tube, and a lid closing the opposite end of said tube, said bottom having a channel formed in the rim thereof, said tube extending into said channel, and means for securing said tube in said channel, said bottom and lid and tube being impervious to moisture.
  • a package of abrasive disks comprising a plurality of disks each having a backing on one side of the disk and having abrasive grit bonded to the other face of said disk, said disks being stacked in substantially axial alignment, a cylindrical tube extending around the circumference of said disks, a bottom closing one end of said tube and having a rim projecting below the center portion of said bottom, a lid closing the opposite end of said tube, said lid having a rim extending around the periphery thereof, said rim being displaced below the central portion of said lid and engaging over the end of said tube, said bottom and lid and tube being impervious to moisture, whereby the bottom rim is received on said lid when packages are stacked on top of each other.
