TH32434A - Cellulose casing for stuffing meat products - Google Patents

Abstract

Areas containing protective agents, particularly polyvinyl chloride (PVDC), are impermeable to both gases and liquids, thus creating zones that display symbols, text, anagrams, or other designs. When the cellulose casing is filled with fatty meat and smoked or colored through the casing, the protective agent creates a layer that hinders subsequent absorption. That is, only the smoking or coloring that penetrates these areas of the cellulose casing, which haven't reacted with the protective agent, creates a color that forms a background where the printed devices appear as a dimensional image, precisely positioned according to the design on the cellulose casing. When the casing is finally peeled off, these "prints" are appropriately transferred onto the sausage.

Claims (34)

1. A cellulose casing for stuffing meat products, consisting of a tubular body of unlimited length designed to receive the meat and fat during the stuffing process to create a stuffed meat product. This casing is removed after at least one subsequent step in the smoking, heat treatment, and coloring processes—a subsequent step including at least one marking operation for applying a marking agent to the meat product. The casing consists of such a tubular body with a single, discontinuous layer of protective material in a chosen pattern to provide an obstruction to the passage of the marking agent, defining areas of color difference on the surface of the meat product after the marking operation and after the removal of the cellulose casing to create a stuffed meat product with areas of color difference. 2. The cellulose casing for stuffing meat products, as described in Claim 1, is permeable to liquids. 3. The cellulose casing for stuffing meat products, as described in Claim 1, is permeable to gases. 4. The cellulose casing for stuffing meat products, as described in Claim 1, is permeable to liquids and gases. 5. Cellulose casing for stuffing meat products, as specified in claim 1, is manufactured by Mezzotint. 6. Cellulose casings for stuffing meat products, as specified in Claim 1, are printed by flexography. 7. The cellulose casing for stuffing meat products, as specified in Claim 1, is printed with spray ink. 8. The cellulose casing for stuffing meat products, as specified in Claim 1, is printed by any means of printing. 9. Cellulose casing for stuffing meat products, as stated in Patent 1. The protective substance is polyamide. 10. Cellulose casing for stuffing meat products, as per claim 9, a polyamide carrying a crosslinking agent that promotes optimal adhesion of the casing to the cellulose. 11. Cellulose casing for stuffing meat products, as per claim 9, a polyamide carrying a wax that prevents self-adhesion of the protective substance when the cellulose casing is folded. 12. Cellulose casing for stuffing meat products, as in claim 9, a polyamide that carries a pigment supplied to it with a visible coloring agent. 13. Cellulose casing for stuffing meat products, as per claim 9. Protective agents are polyamides carrying crosslinking agents, waxes, and coloring agents. 14. Cellulose casing for stuffing meat products, as stated in Patent 1. The protective substance is polyacrylonitrile. 15. Cellulose casing for stuffing meat products, as per claim 14, polyacrylonitrile carrying a crosslinking agent that promotes optimal adhesion of the casing to the cellulose. 16. Cellulose casing for stuffing meat products as per claim 14, a polyacrylonitrile carrying a wax that prevents the self-adhesion of the protective substance when the cellulose casing is folded. 17. Cellulose casing for stuffing meat products as per claim 14, polyacrylonitrile carrying a pigment supplied to it with a visible coloring agent. 18. Cellulose casings for stuffing meat products as per claims 14 or 17. Protective agents are polyacrylonitrile carrying crosslinking agents, waxes, and coloring agents. 19. Cellulose casings for stuffing meat products, as specified in Patent 1, are protected by the ethylene vinyl alcohol copolymer (EVOH). 20. Cellulose casing for stuffing meat products, as per claim 19, ethylene vinyl alcohol copolymer (EVOH) carrying a crosslinking agent that promotes proper adhesion to the casing's cellulose. 21. Cellulose casing for stuffing meat products as per claim 19, ethylene vinyl alcohol copolymer (EVOH) carrying a wax that prevents self-adhesion of the protective substance when the cellulose casing is folded. 22. Cellulose casings for stuffing meat products, as per claim 19, ethylene vinyl alcohol copolymer (EVOH) carrying a pigment supplied to it with a visible coloring agent. 23. Cellulose casings for stuffing meat products, as per claim 19, with the protective agent being ethylene vinyl alcohol copolymer (EVOH) carrying crosslinking agent, wax and coloring agent. 24. Cellulose casings for stuffing meat products as per claim 1. The pattern may be in the form of symbols, lettering, or anagrams. 25. The protective substance is located on the inner anterior portion of the cellulose casing used for stuffing meat products, as per claim 1. 26. Cellulose casings for stuffing meat products as per Reputation 1, where the pattern is appropriately visible on the cellulose casing. 27. Cellulose casing for stuffing meat products as per claim 1, where the pattern is a background print, leaving the casing area for symbols, lettering or anagrams free of protective agents, the area is suitable for the insertion of the marking agent in such a way that the marking is achieved directly on the area placed in the free of protective agents. 28. Sausages made with cellulose casings in compliance with claims 1 through 27. 29. A cellulose casing for stuffing meat products, consisting of a tubular body of unlimited length designed to receive the meat and fat during the stuffing process to create a stuffed meat product. This casing is removed after at least one subsequent step of smoking, heat treatment, and coloring; a subsequent step including at least one marking operation for applying a marking agent to the meat product. The casing consists of such a tubular body with a single, discontinuous layer of a protective agent in a chosen pattern to provide a barrier to the passage of the marking agent, defining areas of color difference on the surface of the meat product after the marking operation and after the removal of the cellulose casing to create a stuffed meat product with areas of color difference. The protective agent is polyvinylidine chloride (PVDC). 30. Cellulose casing for stuffing meat products as per claim 29, polyvinylidene chloride (PVDC) carrying a crosslinking agent that promotes optimal adhesion of the casing to the cellulose. 31. Cellulose casing for stuffing meat products, as per claim 29, polyvinylidene chloride (PVDC) carrying a wax that prevents the self-adhesion of the protective agent when the cellulose casing is folded. 32. Cellulose casings for stuffing meat products as per claim 29, polyvinylidene chloride (PVDC) carrying a pigment supplied to it with a visible coloring agent. 33. Cellulose casing for stuffing meat products as per claim 29. The protective agent is polyvinylidine chloride (PVDC) which carries the crosslinking agent, wax and coloring agent. 34. A cellulose casing for stuffing meat products, consisting of a tubular body of unlimited length designed to receive the meat and fat during the stuffing process to create a stuffed meat product. This casing is removed after at least one subsequent step of smoking, heat treatment, and coloring; a subsequent step including at least one marking operation for applying a marking agent to the meat product. The casing consists of such a tubular body with a single, discontinuous layer of a protective substance in a chosen pattern to provide a barrier to the passage of the marking agent, defining areas of color difference on the surface of the meat product after the marking operation and after the removal of the cellulose casing to create a stuffed meat product with areas of color difference. This protective substance is located on the outer face of the cellulose casing.
