CA 2003923
A packaged grease composition for lubrication of fifth wheels on tractor-trailers or similar vehicles is disclosed. The packet consists of a grease composition sealed in a thin walled plastic envelope. The grease filled envelope is placed on the base plate of the fifth wheel and the envelope readily ruptures under pressure when the plates forming the fifth wheel come together releasing the grease to lubricate the plates. The plastic subsequently disintegrates as these plates rotate on each other leaving no environmental waste to dispose of. The envelope may come in different shapes or the lubricant or envelope may be color coded to indicate the type of lubricant contained within the envelope.
