Title:
PACKAGING DEVICE AND WASTE ACCOMMODATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/074706
Kind Code:
A1
Abstract:
The present invention increases a film draw-in force while increasing the reliability of rotating operation of two film draw-out rollers. Drive transmission rollers 53 and 63 made of elastic members are provided at respective ends of each of film draw-out rollers 50 and 60. Accordingly, a rotating force of a motor 70 transmits a rotating force to one film draw-out roller 50 so that the other film draw-out roller 60 can rotate more reliably compared to a conventional structure in which such drive transmission rollers are not provided. Further, because the drive transmission rollers 50 and 60 are made of elastic members, when sealing films 31 and 41 are caught between the opposed drive transmission rollers 50 and 60, breakage such as rupture of the films 31, 41 does not occur.
