Abstract
A waste storage device includes a waste storage part for storing a waste item and a packaging device arranged in an upper part of the waste storage part. The packaging device includes two film feed rollers, two waste sealing rollers which pull out films and are arranged in parallel that the peripheral surfaces thereof are in contact via the pulled out respective films in a normal state and at least one of which has the peripheral surface that is elastically deformed along the shape of the waste item, and a driving part which rotates the rollers. Two friction rollers which are driven and rotated to sandwich the films sealing the waste item having passed between the waste sealing rollers and pull them downward are provided below the waste sealing rollers. The device prevents a waste item sealed with resin films from being caught in rollers such as waste sealing rollers.
