Patent Searching and Data

Document Type and Number:
WIPO Patent Application WO/2017/209285
Kind Code:
A bag-closing device is disclosed which is capable of using general-purpose bags and which keeps the loss of capacity to the necessary minimum, and a shredder is provided which, even when shredded pieces of trash are stored in a bag, does not cause scattering of the shredded pieces of trash when closing the bag. The bag-closing device comprises one pair of horizontally facing winding shafts having tip parts for detachably holding a bag, which is open so as to allow objects to be put inside, at two facing opening edge parts from the outside of the bag, whereby the entire opening edge of the bag containing objects put therein is formed into a single horizontal roll-like shape by driving the one pair of winding shafts to rotate. In addition, the device may be provided with a cabinet, which allows a frame having one pair of winding shafts to be stored therein and to be pulled out therefrom together with a bag in an open state, and configured such that the one pair of winding shafts are restricted from rotating when the frame is pulled out from the cabinet whereas the one pair of winding shafts are allowed to rotate when the frame is placed in the cabinet. It is also feasible to construct a shredder having this bag-closing device installed below a shredding unit. In this case, preferably outer peripheral surfaces at the tips of the winding shafts are formed into a tapered shape.
