    • B65D31/142—Valve bags, i.e. with valves for filling the filling port being formed by folding a flap connected to a side, e.g. block bottoms

Definitions

  • a kind of check valve is formed by the check.
  • the contents can not penetrate into the valve tube, since it is retained by the kickback.
  • an accumulation of the filling material in the return or a filling of the flashback, which is designed like a bag, after filling leads to a compression and closing of the tubular structure.
  • the checklist also prevents unintentional closing or sticking of the valve.
