Automatic film insertion device
First Claim
1. An apparatus for inserting film into a container having contents comprising:
- (a) A film supply station for supplying film; and
(b) a dispensing mechanism said dispensing mechanism receiving the film from the film supply station and dispensing it to the container, the film occupying empty space in the container, whereby the contents present in the container may be compacted by said film for better transport and to prevent the contents from loosely shifting within the container.

Abstract
An automatic film insertion device automatically unwinds a predetermined amount of plastic tubing from a roll, measures the required length, cuts and automatically inserts the cut piece into the mouth of filled pharmaceutical bottles. In one embodiment, a set of rollers receives a sheet of tubing, which is passed to a mandrel that opens the tubing. A guillotine cuts the tubing, and the tubing is pushed by a plow into a receiving member. The tubing is held inside the receiving member via friction until a plunger pushes the tubing out of the receiving member and into the bottle. The plunger then forces the tubing to buckle and remain in the bottle. In a second embodiment, the receiving member comprises a reciprocating tube attached to a shuttle cylinder. During the film advance portion of the cycle, the tube is positioned under a film feed station adjacent a cutting assembly. The film is fed vertically downward by rollers into the receiving member and cut. The film is then pushed from the tube into the headspace of the container, after which an actuator actuates a rod that forces the buckled film below the underside of the container neck so that it does not bounce out of the mouth of the container.

15. A method for preparing contents present in a container for transport such that the contents present in the container may be prevented from loosely shifting within the container comprising the steps of providing a supply of film to a supply station, and dispensing the film from the film supply station into the container such that the film occupies the empty space in the container.

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. - View Dependent Claims (22, 23, 24, 26, 27, 28, 29, 30, 31)

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.

32. A method for automatically inserting filling material into a container having a mouth, headspace and contents to prevent the contents from shifting excessively or being damaged during shipment comprising:
-
(a) advancing a predetermined length of a substantially hydrophobic filling material from a supply disposed on an unwind assembly;
(b) separating the predetermined length of filling material from the supply;
(c) transferring the predetermined length of filling material to a receiving member, the receiving member having an inner surface and an outer surface, and being configured to hold the predetermined length of filling material against its inner surface via friction;
(d) pushing the predetermined length of filling material out of the receiving member and into the container with a force sufficient to cause the predetermined length of filling material to buckle in the headspace of the container;
(e) actuating an elongated member disposed adjacent the receiving member such that the elongated member enters the mouth of the container at a slight angle;
(f) pushing the filling material with the elongated member so that the filling material is forced past an irregular portion of the container;
(g) retracting the elongated member wherein the filling material expands against and abuts the irregular portion of the container;
whereby the filling material is locked at a position between the contents and the mouth of the container thereby preventing the filling material from bouncing back out of the container. - View Dependent Claims (33, 34, 35, 36, 37, 38)
