Definitions
- the present invention relates generally to films used in packaging food products, and more specifically, to containers of unshirred tubular food casings and methods for efficient packaging of such casings for storage, shipment and use by food processors for stuffing with meat, sausage and.cheese products.
- Food casings fabricated from nonedible and edible films have been widely used for many years in processing and packaging various meat products like frankfurters, sausages, bolognas, hams, deli loaves, poultry products and the like.
- the popular unreinforced regenerated cellulose-type casings are prepared, for instance, by extruding tubular viscose in a coagulating bath where it is regenerated, washed, plasticized and dried.
- Fibrous casings for larger meat products are prepared in a similar manner except a paper or other tubular reinforcement is saturated with a continuous matrix of viscose according to known methods. Fibrous film is customarily regenerated, washed to remove by-products, treated with glycerin, dried and formed into flattened tubular film by winding onto large reels.
- casing manufacturers For convenience in handling and filling, it has been the practice of casing manufacturers to convert much of the flat reelstock into tubular strands or sticks on high speed shirring machines. Typically, 40 to 200 feet of casing material is pleated into tightly compacted strands of 10 to 30 inches or more in length and packaged into corrugated caddies for storage and shipment to food processors.
- Other casings such as large diameter fibrous types for heavier meat products, may be supplied by manufacturers as relatively short discontinuous lengths of flattened tubular film which are moistened immediately before use.
- Premoisturized, ready-to-stuff types of casing having sufficient moisture as to eliminate the usual soaking requirements by meat processors prior to stuffing is one example of casing being supplied on large reels.
- Lubricating surfactants when applied to remedy such problems can result in shirred pleats becoming noncoherent making strands difficult to package, store and handle without breaking. Such strands are unacceptable for high speed automated stuffing operations.
- continuous filling operations with shirred strands have poor stuffing efficiencies because of a loss of time for indexing and inserting new strands onto the stuffing horn.
- FIG. 1 Representative examples of flat tubular casing wound onto reels are illustrated in U.S. Patents 4,358,873; 4,276,815; and 3,919,739.
- Such casing may be substantially dry, e.g. 10T. moisture content, where it is transported from the reel through a moisturizing bath prior to stuffing.
- reelstock may contain sufficient moisture in it as to allow shirring and/or stuffing without adding further moisture immediately prior to filling.
- packaging tubular casing on reels offers advantages by eliminating several problems associated with shirred casing, as previously described, reeled film does not eliminate interruptions in filling operations. When film on a reel is exhausted, stuffing operations must be shutdown to allow an operator to attend to threading a fresh reel of tubular film through the stuffing apparatus.
- the packing efficiency i.e...the length of flattened film which can be packaged in a volume of space occupied by reels shipped in a rectangular container, is relatively low because of the annular configuration of storage reels.
- U.S. Patent 3,550,977 and West German Application DE-33 18 373 disclose sausage casing boxes with lengths of unreeled, unshirred tubular film laying across their bases.
- U.S. 3,550,977 discloses a sausage casing box having a base and a cover. The box is packed with separate bundles of natural casings each having up to 360 feet of film folded in a serpentine-like pattern. The box has a water tight liner permitting moisturizing the casing in-situ before use. However, each bundle is removed from the container by an operator and manually transported to the stuffing bench for filling.
- the U.S. patent does not teach as its objective high packing efficiency methods in containerizing flattened tubular film for continuous uninterrupted payout at the stuffing site.
- the present invention generally relates to improved packages of tubular food casing and methods for their manufacture. It was discovered that tubular food film, especially large diameter, nonedible casings for packaging bolognas, deli loaves, whole hams, picnics, poultry, etc., can be packaged advantageously as continuous, uninterrupted flat lengths of tubular film in large, generally rectangular shaped containers with higher packing efficiencies than if wound on reels, or if simply folded to and fro to form multiple stacked layers of piddled casings where one layer is folded to cover the immediate preceding layer. The space occupied by a length of film on reels or folded by stacking layers in a container is greater than the space occupied by the same length of film layered according to the present invention.
- the containers as disclosed herein perform as the sole packaging means for the tubular film at the time of manufacture, storage and shipment to food processors where the filled container is positioned adjacent to a stuffing apparatus. Payout of the film may be directly to the stuffing apparatus. Because the containers high packing efficiency, they can be filled with a day's capacity of casing so that interruption and downtime for rethreading a new supply of film can be totally eliminated.
- the container formed from a base, spaced first and second opposing sidewalls and spaced first and second opposing endwalls is ,filled with a continuous length of flattened food film by passing to and fro between the first and second sidewalls until a first layer covers the container base.
- the film is folded over to make a return pass in the direction opposite from the preceding pass forming a layer as the film moves gradually from the first endwall to the second endwall.
- a zigzag pattern is used to form layers of the film utilizing virtually all available space in the container, including most container corners.
- the walls of the container may be moisture proof allowing for soaking the film in the container by the addition of water thereto by the food processor prior to use.
- the film may be shipped to food processors in a premoistened condition so it can be stuffed without additional moisture being added immediately prior to stuffing.
- the present invention provides for generally rectangular containers which includes substantially square or rectangular shaped cartons and boxes filled with two or more layers of unshirred, flattened tubular film laid out according to the pattern shown in FIG. 1.
- the carton of tubular film 10 has an interior defined by a container base 12, spaced first and second opposing sidewalls 14 and 16 and spaced first and second endwalls 18 and 20.
- a layer of the tubular film 22 in a flattened condition is started by first placing film end 24 at a far end of the container adjacent to the first endwall 18 and container base 12 running the film from the first sidewall 14 to the second sidewall 16 on a diagonal in the direction of arrow 26..
- the film is passed to and fro between the first and second sidewalls 14 and 16 to provide a generally zigzag pattern to the film by means of offset folds 30.
- the left edge 28 of the first layer of film 22 is shown in FIG. 1.
- the offset of the folds is equivalent to about 25 to about 1007. of the width of the flattened film. More preferably, the film offset is equivalent to about 35 to about 757. of the width of the flattened film, and most optimally, approximately 507. of the film width.
- the angle of offset folds 30 is reversed causing the second layer of film to gradually advance from the second endwall back to the first endwall 18 as passes of the film are made back and forth in a generally zigzag pattern between the sidewalls of the container.
- second and subsequent layers of the flattened tubular film are formed in a crisscross pattern with the previous layer.
- the film is preferably layered so the folds 30 are formed when the sidewall is reached.
- folds may also be formed before the sidewall has been reached during a given pass when a looser, less dense pack is desired, for instance, where some additional space is needed for water added to the container prior to stuffing for in-situ moistening.
- one further feature of the present invention includes a sufficient length of continuous casing in a single container for a day's stuffing in order to avoid interruption and lost production.
- Sufficient casing for a day's stuffing is intended to mean that amount of tubular film in a single container to last for at least one production shift. This would include containers of layered tubular film mounted on pallets 31, like that shown in FIGS. 2-4.
- a lift truck (not shown) may transfer a large carton of casing on a pallet adjacent to a stuffing apparatus at the beginning of a production shift and be allowed to run continuously without interruption and with minimal operator supervision required. Payout of the film takes place from the carton directly to the stuffing apparatus.
- a container for example, 48 inches long, 40 inches wide and 40 inches deep filled with tubular food casing having a flat width of 10 inches and packed with 5 inch (50%) offset folds.
- a container would be capable of holding a layer of 12-48 inch long sections (see FIG. 1).
- a container of this dimension would have a capacity of from about 10,000 to about 15,000 feet of casing compared to a reel which would hold only from 750 to 1,000 feet of flattened tubular casing.
- Smaller lighter weight containers of layered casing are also contemplated according to the present invention. Such containers may have less casing than required for a day's stuffing.
- This embodiment includes layering the film into the container such that the trailing end of the casing 32 (FIG. 3) is accessible during payout of the film. This permits additional containers of film to be spliced to the trailing end eliminating downtime intervals and production interruptions for rethreading purposes.
- the containerized casings disclosed herein are intended for all types of casings, including edible and nonedible, small diameter non-fibrous reinforced as well as larger size fibrous reinforced casings for stuffing frankfurters, sausage links, bolognas, hams, deli loaves, poultry and turkey loaves, etc.
- the invention is especially desirable for premoisturized, ready-to-stuff type casings which are manufactured and packaged with sufficient moisture as to eliminate prestuffing soaking operations.
- Such casings are packaged in cartons having polyethylene or other type moisture barriers.
- the casings of the present invention may also be layered in polyolefin container inserts or bags.
- the containers themselves may be of any standard form of boxes customarily used in packaging operations, such as corrugated paperboard boxes, thermoplastic containers, paperboard boxes with moisture proof liners, etc.
