Textile intestine sections with opening aid

Abstract

A textile gut section made of a coated textile material, composed of two identical halves which are joined at the edges, but not in the area of ​​an opening (1), by a seam (2), characterized in that the coated textile material essentially consists of a textile carrier material which is coated identically on both sides, wherein the two halves each have a non-centrally arranged recess (3) in the area of ​​the opening and the two halves are oriented to each other such that the recesses are located at different places of the opening and do not overlap or only overlap slightly.

Description

[0001] The invention relates to textile casing sections for packaging foodstuffs, which have an opening on one side for filling.

[0002] Food casings based on coated textile material are known and described, for example, in the monograph by B.-A. Lang and G. Effenberger “Sausage casings - artificial intestine”, Deutscher Fachverlag GmbH, Frankfurt, 3rd edition

[2006] pp. 71 / 72.

[0003] Also known are sections of artificial intestine that are closed on one side, e.g. from DE 102 25 619 A1.

[0004] A solution to this problem is presented in Polish utility model PL 69751 Y1. This patent discloses a food wrapper, open on one side, composed of two layers of material. The two layers are joined at their edges, for example, by a glued, welded, or sewn seam. The layers can be made of coated textile material. At one edge on one side of the opening, the two layers are not joined, allowing a corner of one layer to be folded over. This facilitates opening the wrapper.

[0005] One-sided closed artificial intestine sections made of seamless, tubular, single- or multi-layered plastic material are described in WO 03 / 103405 A1 (= DE10 225 619 A1 and PL 372752 A). The sections are closed at one end by a flat transverse seam. The inner surface of the sections preferably has a heat-sealable layer. Heat sealing in the area of ​​the transverse seam allows the sections to be sealed grease-tight on one side. The seamless, tubular plastic material is produced by extrusion or co-extrusion. Accordingly, it does not include a textile backing material.

[0006] The task therefore remained to modify textile gut sections that are open on one side so that they can be easily opened by hand even when soaked.

[0007] The problem was solved by creating two recesses in the opening area that do not overlap or only overlap to a small extent.

[0008] The invention relates to a textile gut section made of a coated textile material, which is composed of two identical halves (side A and side B) that are joined together at the edges, but not in the area of ​​an opening, by a seam (1), characterized in that the coated textile material essentially consists of a textile carrier material that is coated identically on both sides, wherein the two halves each have a non-centrally arranged recess in the area of ​​the opening and the two halves are oriented to each other such that the recesses are located at different places of the opening and do not overlap or only overlap slightly (i.e., not more than 20%).

[0009] The seam (2) is preferably a sewn seam. The edges of the two sections can also be welded together. To create a particularly grease-resistant and strong seam, the edges of the two sections can additionally be joined by heat sealing or welding.

[0010] The term ‘not centered’ used in connection with the recess (3) refers to an imaginary axis of symmetry that runs in the longitudinal direction of the textile gut section through the center of the opening (1) of the section.

[0011] The textile casing sections according to the invention have an elongated shape with an open and a closed end. They thus essentially have the shape of a pouch. The closed end preferably has a more or less rounded shape. The textile casing sections are composed of two identical halves. Each half has a recess on the side intended for the opening (1), which is not arranged centrally, as shown in Fig. Figure 1 shows the process. The two halves are placed on top of each other and joined together such that the recesses (3) are located in different positions and do not overlap, or only overlap slightly. The recesses themselves preferably have a rounded to semicircular shape to prevent the casing from tearing at these points during subsequent filling with the food. The size of the recesses (3) is such that each half of the casing can be grasped with the fingers of one hand. Advantageously, the recess has a maximum depth of 0.5 to 2.0 cm, preferably 1.0 to 1.5 cm, measured from the edge of the opening (1). In this way, the textile casing sections can be opened easily and quickly before filling.

[0012] A textile gut section according to the invention is in Fig. Figure 1 illustrates the following. The length of a section is preferably about 350 to 450 mm, more preferably 370 to 420 mm, and the maximum width in the flattened state is 150 to 230 mm, more preferably 160 to 210 mm. The width of the opening of the flattened casing is expediently about 70 to 150 mm, more preferably about 80 to 120 mm. Such a section holds about 2.5 kg of food. The food is preferably sausage meat. The sections can, of course, also have a smaller or larger filling volume than that required for 2.5 kg of sausage meat. A filling volume of 300 ml to 3,000 ml, more preferably 400 to 2,000 ml, and particularly preferably 500 to 1,500 ml has proven advantageous.

[0013] The material of the textile gut sections according to the invention is a carrier material coated on both sides. The carrier material is, for example, a woven, knitted, nonwoven, or crocheted fabric. It can consist of fibers made of cotton, linen, rayon, hemp, flax, and / or synthetic fibers. It generally has a weight of 15 to 110 g / m². 2 It is coated on one side.

[0014] The substrate is coated with a coating paste comprising an aqueous dispersion of a thermoplastic polymer, thickeners, and optionally dyes and / or color pigments. Particularly suitable thermoplastic polymers are those based on polyacrylates and / or polymethacrylates (collectively referred to below as "poly(meth)acrylates"). Of these, poly(methyl(meth)acrylate) and poly(n-butyl(meth)acrylate) have proven especially suitable. The poly(meth)acrylates may contain monomer units with crosslinking properties. These are, for example, monomer units of (meth)acrylic acid esters with polyols, such as ethylene glycol di(meth)acrylate, triglycol di(meth)acrylate, trimethylolpropane tri(meth)acrylate, or allyl(meth)acrylate.In a particular embodiment, the coating paste comprises, in addition to poly(meth)acrylates, other natural or synthetic polymers, such as polyvinylpyrrolidone, polyacrylamide, copolymers with vinyl alcohol units, or proteins. The color pigments are preferably fat-insoluble. The viscosity of the coating paste is expediently in the range of 20,000 to 80,000 mPa s. The coating can be applied in two or more steps and accordingly comprise two or more layers, produced with coating pastes of the same or different composition. The additional layers are, for example, layers with barrier properties for water vapor and / or oxygen. Depending on the type of coating of the substrate material, the textile gut sections according to the invention can also be more or less permeable to water vapor and / or oxygen. This depends on the type of food to be packaged.By selecting a sufficiently permeable coating, food contained within the textile casing section can also be smoked. With a textile material made of coarse yarn, the textile structure may still be visible after coating. The total weight of the coating(s) (after drying) is generally 7 to 80 g / m². 2 on one side of the substrate. The coating paste can be applied using standard equipment such as roller squeegees, air squeegees, or blanket squeegees. The layers created with the coating paste are then dried, for example, at a temperature of 100 to 180 °C for a period of 30 seconds to 2 minutes. If desired, a specific texture can be created on the surface of the coating using an embossing roller, e.g., a pattern with numerous small bumps (similar to "chicken skin").

[0015] The uniform coating ensures that the surface of the finished cover has the same structure, gloss, and color throughout. This is important because one of the two halves is turned over and placed on top of the other. The two halves are then joined at the edges, generally with a sewn seam (2). Additionally, the thermoplastic coatings on both halves can be heat-sealed or welded together at the edges to increase the cover's tightness, particularly its grease resistance.

[0016] A particular advantage of the textile casing sections according to the invention is that the two halves can be die-cut from a textile material uniformly coated on both sides using the same device and the same tool. The textile casing sections preferably have wave-shaped contoured lateral edges, as shown in Fig.1 shown.

[0017] The sections according to the invention are used as packaging for sausage meat, specifically sausage meat based on chicken, pork, beef, or other animal and / or plant-based foods. The sausage meat is preferably salami meat. It can be smoked inside the textile casing section.
