Description

[Detailed Description of the Invention] Kishin I-ko 1 The present invention relates to a film for packing food, and specifically,
Tubular food casings that are not shirred and used for storage and transportation, and for filling sausages, cheese, meat, etc.
Regarding how to pack that casing.

Food-grade casings have long been used to process and package foods such as frankfurters, bologna, ham and chicken. Typical low reinforcement regenerated cellulose-viscose casings are made by extruding tubular viscose into a coagulation bath where it is regenerated, washed, plasticized and dried.

Fibrous casings for large meat products are made in a manner similar to the conventional casings described above, except that paper or other tubular reinforcement is impregnated with continuous viscose material in a manner well known. The fibrous casing is generally recycled, washed, treated with glycerine, dried, and rolled onto large reels into flat tubular casings.

For ease of handling and filling, the casing, which is flattened on a reel, is formed into tubular strands (or sticks) by means of a high-speed shearing machine. Typically, about 12 to 60 meters (40 to 200 feet) of casing is shirred into compact strands of 0.251 to 0.762 meters (10 to 30 inches) or more, and the food Packed into boxes for transport to the vendor. Large diameter casings, such as for large meat products, may also be supplied flattened and relatively short, in which case they are moistened just before they are used. A type of casing that is fully moistened to eliminate the normal soaking required by meat processors before filling is an example of casing that is fed on large reels.

Casing wound on a reel and shirred s1
-Land has become standard, but it has not been completely satisfactory for casing manufacturing and food processing. For example, shirred strands tend to tear easily and the end walls are often not shirred.

When shearing a tubular film, if the film is not properly moistened, problems such as sticking of the film to the mandrel and clogging occur. Overwetting the film will cause it to become overly plastic;
If it is filled with contents, it will be overfilled, and if the moisture content is low, it will easily tear due to pinholes. Attempts to solve these problems by applying surfactants during filling can result in irregular pleats in the shirred film, making it susceptible to tearing during packaging, storage, and handling of the strands. Such strands are not suitable for high speed automatic filling operations. If a strand breaks, it takes time to load a new strand, wasting time.

A typical example of a casing wound on a reel is U.S. Pat. No. 4,358,873, No. 4°276.8.
No. 15, and No. 3,919,739. Such casings are dry, for example with a moisture content of around 10%, and are passed through a humidification bath before entering the filling operation. Some casings wound on reels have sufficient moisture, in which case there is no need to pass them through a humidification bath before shearing or filling. Although casing on a reel can eliminate the above-mentioned problems of shirred casing, it does not eliminate the wasted time taken to connect casing during the filling operation, once the strands on the reel are gone. The filling operation must be interrupted and a new casing passed through the filling machine. Therefore, production efficiency is poor. Furthermore, the casing wound on a reel is inefficient for storage, considering the space the reel occupies and its circular shape.

Attempts have also been made to remove the reel as a method of packaging the casing for transportation, storage, and distribution for filling. U.S. Patent No. 3,550,
No. 977 and German application DE-3318373 disclose storage boxes in which a casing that is not wound on a reel or shirred is laid across the bottom wall of the storage box. Each box is about 110 meters long (360
Each bundle is made by bending the natural casing of 1-) into a serpentine shape. The box has a watertight liner and the casing is kept wet before use. However, each casing must be removed from the box one by one by an operator and manually passed through the filling machine. The above US patent does not discuss packaging flat casings at high speed so that the casings can be removed without interruption during filling.

German patent application DE-3318373 describes an Enstubular casing which minimizes interruptions in continuous filling by looping the casing into a box. The folded part is stacked on top of the previous folded part.

Such a method of storing the tubular casing by folding it loosely does not make sufficient use of the internal space of the storage box.

In view of the above points, the present invention provides shirring (shirring)
In addition to efficiently storing unfilled casings in a relatively small storage space and making them easier to transport, the casings are continuously stored at 0° l u us so that filling operations are not interrupted when filling the contents. *Z,k

The first end wall is moved from the previous folded part to the second end wall, and the second layer is made, and the required number of layers are made in the same manner. do.

Furthermore, the packaging casing according to the present invention is an unshirred flat casing packed in two or more layers in a substantially rectangular box, and the inside of the box has a bottom wall, first and second opposed arrangement. a first and second opposed end wall, and a lid, each layer being folded back and forth between the first and second side walls, with the first layer extending from the first end wall to the second end wall. Each fold is offset relative to the previous fold so that the second layer progresses in a zigzag manner toward the end wall (1) from the second end wall toward the first end wall. It is characterized by The present invention has the above-mentioned configuration, and is capable of efficiently storing items in a relatively small box.
The above-mentioned objective can therefore be achieved. DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on embodiments shown in the accompanying drawings.

The present invention includes square or rectangular cartons and sheaths filled with two or more layers of unshirred, flat tubular film or casing patterned into a layerer 1 as shown in FIG. A generally rectangular storage container is provided. The box 10 includes a bottom wall 12, first and second side walls 14.16, and first and second end walls 18.2.
0. The flattened tubular casing 22 is first placed on the bottom wall 12 near the first end wall 18 and the first side wall and laid diagonally towards the second side wall 16. When the casing reaches the second side wall, it is folded back at the folded portion 30.

The folded section is angled one inch closer to the second end wall as it advances and is offset from the section in front of it.

The casing is folded back in a zigzag manner between the first and second side walls. The left edge of each folded portion of the first layer thus produced is indicated at 28. The offset of each fold is approximately 25 to 1 of the width of the casing.
00%. Preferably it is between 35 and 75 percent, with 50 percent being most preferred.

When the casing reaches the second end wall, the angle of the fold is reversed so that it now zigzags between the side walls in the opposite direction from the second end wall 20 towards the first end wall. Therefore,
The second and subsequent layer of casing becomes transverse to the fold of the previous layer of casing. For the most favorable packaging efficiency, the casing should be folded as it reaches each side wall. However, if, for example, space is required to put water into the box before filling, it is necessary to make a bend 30 before reaching the side wall and pack it loosely. It can be decided according to. However, a feature of the invention is to minimize the interruptions caused by joining the casings during the day's filling operation, and to provide the casings with sufficient length for this purpose. Enough casing for one day's filling operation means storing enough casing in one box to last for at least one production shift. FIGS. 2-4 show a layered casing box mounted on a bullet 31. FIG.

This box is delivered to the filling station at the beginning of the day when the filling operation begins (a lift truck (not shown) is fed directly from this box to the filling machine.

Such a box would have a width of about 25.4 centimeters (10 inches) and a width of about 12.7 centimeters (or 5 centimeters), or about 12 to 122 centimeters (12 to 122 centimeters) filled with 50 percent folded casings. 48 inches) long, about 10 J? There are about 30 such boxes.
It is possible to hold layers of length between 12 and 48 inches. A box of this size is 1
8.75 meters to 25.4 meters (750-1
250.4 meters to 381 meters (100 inches) compared to a reel holding a casing of 250.4 meters to 381 meters (100 inches)
It has the capacity to accommodate casings from 0.00 to 15000 inches. The present invention also contemplates providing a box containing a small and lightweight casing. Such boxes contain casings that are less than the length required for one day's filling operation. In this case, the end wall 32 (Fig. 3) of the casing that is paid out last can be contacted from the outside of the box, and before the casing is completely paid out, the next casing It is made to connect. This makes it possible to avoid interruptions in work.

The casings stored in the boxes described above are not limited to edible ones, and are not limited to small-diameter reinforced casings, but also include large-diameter ones such as frankfurton sedges and gnomes. The present invention is suitable for casings containing sufficient moisture to obviate the need for moistening operations prior to filling operations. Such boxes include polyethylene or other moisture barrier materials. The box according to the present invention can have a layer made of a polyolefin inner box or bag. It can be in the form of a box that is commonly used.
