Abstract
A lubricant sheet comprises a blank of material folded along a fold line into a folded configuration to form a lubricant containment pocket; a lubricant in the lubricant containment pocket; and a primary barrier for the lubricant. The primary barrier extends around and seals the lubricant containment pocket to hold the lubricant in the lubricant containment pocket. The blank of material includes a fold of material along the fold line forming a secondary barrier for the lubricant. When the lubricant in the lubricant containment pocket is being compressed during shredding of the lubricant sheet so as to cause some of the lubricant to be released through the primary barrier, the secondary barrier is configured to deflect the released lubricant that is released towards the secondary barrier.
Claims12
A lubricant sheet configured to be used in a shredder to provide lubrication between cutter elements of the shredder, the lubricant sheet comprising:
- a blank of material folded along a fold line into a folded configuration to form a lubricant containment pocket;
- a lubricant in the lubricant containment pocket;
- and
- a primary barrier for the lubricant, the primary barrier extending around and sealing the lubricant containment pocket so as to hold the lubricant in the lubricant containment pocket;
- the blank of material comprising a fold of material along the fold line forming a secondary barrier for the lubricant,
- wherein the secondary barrier is configured to deflect lubricant that is released from the lubricant containment pocket through the primary barrier and towards the secondary barrier in response to being compressed during shredding of the lubricant sheet so as to relieve pressure in the released lubricant and to maintain the released lubricant in place for further lubrication of the cutter elements of the shredder.
A lubricant sheet assembly configured to be used in a shredder to provide lubrication between cutter elements of the shredder, the lubricant sheet assembly comprising:
- at least two blanks of material overlapping each other to form a lubricant containment pocket;
- a lubricant in the lubricant containment pocket;
- and
- a primary barrier for the lubricant, the primary barrier extending around and sealing the lubricant containment pocket so as to hold the lubricant in the lubricant containment pocket;
- at least one of the blanks of material folded along a fold line and comprising a fold of material along the fold line forming a secondary barrier for the lubricant,
- wherein the secondary barrier is configured to deflect lubricant that is released from the lubricant containment pocket through the primary barrier and towards the secondary barrier in response to being compressed during shredding of the lubricant sheet assembly so as to relieve pressure in the released lubricant and to maintain the released lubricant in place for further lubrication of the cutter elements of the shredder.
