Rollers to seal waste between film sheets

摘要

A waste disposal device comprises first 600 and second 602 rollers, each comprising first 605 and second 610 end portions and a joining portion 608 therebetween. The end portions receive and seal first and second film portions therebetween as the rollers rotate. The joining portions 608 define an aperture 606 for receiving waste in a first rotary configuration and seal the film portions therebetween in a second rotary configuration. The cassette 400 comprises first and second film dispensers 402, 404 connected together. The cassette can expand or contract. Ideally the film dispenser can be installed in the device via the main disposal aperture. The rollers can be biased together, the rotation of one causing the rotation of the other so that their end portions are in contact throughout their rotation to seal the sheets edges to form a tube. The central joining portion could have the cross section of a sector of a circle.
