SPOOL FOR A WASTE STORAGE DEVICE |
摘要 |
A spool (10) for storing film for a waste storage device includes a core (12) and a flared funnel portion (14). Film is stored on the core (12) and can be retained in place by shrink-wrapping (34) as a result of which the core can be formed without an outer wall or base, reducing material and moulding costs.
