Beschreibung
Zusammenfassung:	A container ( 1 ) for releasing a chemical additive ( 7 ) in a fluid material selected from a lubricant or hydraulic fluid composition comprises a fluid material-impermeable casing ( 3 ) having a hollow interior and an additive composition ( 7 ) comprising at least one fluid material-soluble additive. The additive ( 7 ) is held within the container ( 1 ) by a least one fluid material-permeable element ( 11 ) provided at or near an opening ( 13 ) in the casing ( 1 ) and is effective to provide for release of additive(s) ( 7 ) into the fluid material. Methods of releasing additives ( 7 ) into fluid material are also provided.
