Abstract

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.

Claims

1. A spool for storing tubular film comprising a flared end and an opposing loading end arranged to receive the film loaded in a direction towards the flared end.

2. A spool as claimed in claim 1 in which the flared end includes a funnel.

3. A spool as claimed in claim 1 in which the flared end includes cut-out portions.

4. A spool as claimed in claim 1 further comprising tubular film loaded thereon.

7. A waste storage device comprising a waste storage opening, a waste storage space and a spool therebetween and arranged to dispense film for storage of waste, the spool including a flared end and a loading end.

8. A method of loading tubular film onto a spool having a flared end and a loading end comprising the steps of mounting the spool with the loading end disposed towards a film dispenser, and loading the film from the film dispenser onto the spool.

9. A method as claimed in claim 8 further comprising the step of compressing the loaded film onto the spool.

10. A method as claimed in claim 8 further comprising the step of loading a compression ring against the loaded film.
