Method and apparatus for filling and sealing containers

A method of introducing a flowable material into and of sealing such material in the bags of containers which further include boxes for the bags, comprising the steps of introducing boxes which are open at two opposite ends thereof into a first portion of a predetermined conveyance path;

• inserting empty bags, each of which has an open end and a closed end, into successive boxes in a second portion of said path so that the closed end of the bag enters into and the open end of the bag is accessible via one open end of the respective box;
• introducing flowable material through the open ends of and into successive bags in third portion of said path;
• maintaining the open ends of successive bags outside of the respective boxes, at least in a fourth portion of said path;
• sealing the open ends of successive bags in said fourth portion of said path;
• and thereupon effecting relative movement between successive bags and the associated boxes so as to introduce the sealed ends of successive bags into the respective boxes, including shifting successive boxes relative to the respective bags.

Apparatus for introducing a flowable material into and for sealing such material in bags of containers which further include boxes for the bags, comprising means for transporting boxes which are open at the top and bottom in a predetermined direction and along an elongated path;

• means for inserting empty bags, each of which is open at its upper end and closed at its lower end, through the open tops of and into successive boxes in a first portion of said path;
• means for admitting flowable material through the open upper ends of and into the interior of successive bags in a second portion of said path;
• means for sealing the open upper ends of filled bags in a third portion of said path downstream of said first portion, as considered in said direction;
• and means for effecting a relative movement between the boxes and the respective bags in a fourth portion of said path downstream of said third portion so that each filled and sealed bag is fully confined in the corresponding box.

• support means for maintaining the open ends of bags at a level above the tops of the respective boxes in said third portion of said path, including platforms and conveyor means for introducing platforms from below into successive boxes ahead of said third portion and for withdrawing the platforms from successive boxes downstream of said third portion, as considered in the direction of transport of boxes along said path;
• and means for effecting a relative movement between the boxes and the respective bags in a fourth portion of said path so that each filled and sealed bag is fully confined in the corresponding box.
