Spool for a waste storage device

摘要

The spool (10) includes a core (12) and a flared funnel portion (14). Tubular film is stored on the core and can be retained in place by shrink-wrapping as a result of which the core can be formed without an outer wall or base, reducing material and moulding costs. Independent claims are included for a waste storage device and a method of loading tubular film onto a spool having a flared end and a loading end.
