Abstract
A de-aeration and vacuum packaging apparatus includes porous closeable disks and a tight closing, anti-pollution filler device. The apparatus is suitable for use with a machine adapted for filling packages with a freely flowing material which includes bag supporting means comprising a clamping part formed intergral with a horizontal support which is equipped at each end with slides serving as a guide for sliding supports, each slide including side sections fitted with grips linked together by hinges or by a flexible belt. Portions of the apparatus subjacent to the vertical hinges, along with a flexible spout are distortable in the lower part thereof through hinged plates connected to the vertical hinges. Reciprocating means connected to opposite sides of the hinged portions provide lateral pressure to conform the hinged portions to the distortable part of the spout in order to prevent escape of pollutive materials during the filling process.
