- 20. An automatic film insertion device comprising:
(a) a set of rollers configured to receive flattened hydrophobic tubing material from a supply of tubing material and to advance a predetermined length of the tubing material; (b) a mandrel being configured and positioned so that it opens the predetermined length of tubing material after it passes through the set of rollers, thereby causing the tubing material to form an open tube; (c) a cutting assembly that separates the open tube from the supply of tubing material; (d) a receiving member having an activated position and a closed position and having inner and outer walls, the receiving member being configured such that, in the activated position, it opens to receive the open tube, and when in the closed position maintains the open tube against its inner walls; (e) a plow configured such that it pushes the open tube into the receiving member when the receiving member is in the activated position; and (f) a plunger configured to be inserted into the receiving member, so that when the plunger is inserted into the receiving member it forces the opened tube down through the receiving member into a container so that the open tube buckles and remains in the container.
- 21. A method for automatically inserting filling material into a container having contents comprising:
(a) providing supply of filling material, wherein the filling material has an inner surface and an outer surface; (b) advancing a predetermined length of the filling material; (c) opening the predetermined length of the filling material to form an open tube; (d) separating the open tube from the supply; (e) placing the open tube of filling material into a receiving member having an inner surface and an outer surface, the receiving member being configured so that the open tube will contact the inner surface of the receiving member and be held in the receiving member via friction; (f) positioning a container underneath the receiving member; and (g) inserting a plunger into the receiving member so that the plunger pushes the filling material into the container.
- 22. The method of claim 21 wherein the filling material comprises a plastic tubing material.
- 23. The method of claim 21 wherein the receiving member comprises a cylinder including a first portion and a second portion that move together and apart in relation to each other to open and close the cylinder.
- 24. The method of claim 23 comprising the step of placing the filling material into the receiving member when the first and second portions are apart, and then pushing the first and second portions together to frictionally hold the filling material in the receiving member.
- 25. A device for automatically inserting filling material into a container having contents comprising:
(a) a supply of filling material disposed on an unwind assembly, the filling material being substantially hydrophobic; (b) a separating means for separating a predetermined length of filling material from the supply of filling material, the separating means being disposed downstream of the unwind assembly; (c) a container with contents having a headspace area and a mouth; (d) a receiving member having an inner surface and an outer surface, the receiving member being configured to hold the predetermined length of filling material against its inner surface via friction; (e) an insertion member disposed downstream of the separating means and configured to push the predetermined length of filling material out of the receiving member and into the container; (f) an actuator disposed adjacent the receiving member and configured to actuate an elongated member into the container; wherein the insertion member travels into the mouth of the container and forces the predetermined length of filling material to buckle in the head space area of the container, and wherein the actuator actuates the elongated member into the container to force the predetermined length of filling material to lock into a position disposed below the mouth of the container, thereby preventing the filling material from bouncing back out of the container.
