Abstract
A lubrication package for lubrication of paper shredders wherein a lubricant is sandwiched between two coversheets which are sealed together near their peripheral edges to contain the lubricant. When the package is inserted into an operating paper shredder, the coversheets are shredded and release the lubricant to lubricate the shredding mechanism. The lubricant is prevented from all migrating towards one of the peripheral edges by interior seals that divide the package into at least two interior regions that do not contact sealed together peripheral edges of the package.
Claims3
A lubrication package to be shredded by a paper shredder so as to lubricate the paper shredder, said package comprising:
- two juxtaposed cover layers having peripheral edges;
- a peripheral seal bonding the peripheral edges of the two cover layers together;
- a lubricant disposed in a space between the two bonded cover layers;
- and
- inner seals spaced apart from the peripheral seal, said inner seals not in contact with the peripheral seal or in contact with or continuous with any seals in contact with the peripheral seal, to separate the space into at least two interior regions not in contact with the peripheral seal and one peripheral region in contact with the peripheral seal, wherein the inner seals do not contact the peripheral seal.
