Easy-to-open food packaging component and method

Abstract

The invention provides an easy-to-open PVDC packaged sausage-shaped food such as ham sausage, a cheap, reliable and easy-to-implement packaging method and components, which can be realized only by changing the nail-pressing mold of the existing packaging line. . Specifically, punch out the sharp part, guard part and pressure part at one end of the nail. The sharp part faces the direction of the casing column, and the lower part of the casing bundle is opposite to the seam of the casing. The sharp part is slightly raised including the hypotenuse. The short side and the beveled side are smooth to prevent accidental damage to the casing, the short side is sharp and easy to puncture the casing, the guard part covers the sharp part, and the pressure part is easy to press. When opening, press the pressing part and use the beveled edge of the sharp part to press the sausage body into a depression, then push the nail body toward the sharp part to make a small hole under the casing bundle at the opposite side of the casing seam, and then pull it toward the casing seam The tied casing bundle (the casing will break from the small hole when pulled, but the longitudinal seam of the casing will not be easily broken due to two layers), and then tear the entire casing down along the longitudinal seam direction of the casing.

Description

technical field [0001] The invention relates to the field of food packaging, in particular to PVDC-packaged sausage-shaped food such as ham sausage and the like. Background technique [0002] Ham sausages are generally packaged with PVDC casings and aluminum buckles tied at both ends. People usually open the casing by biting off the aluminum buckle and tearing the casing or twisting it into two pieces from the middle and squeezing out the sausage meat, or using a knife, toothpick, etc. The tool scratches and punctures the casing and tears it apart. There are tools in the above method that it is impossible to carry with you, and it may scratch your hands, bite your teeth, not elegant, and it is laborious and slow to unscrew. [0003] There are patents disclosing the following easy-to-open ham sausage solutions: [0004] 201520417485.4 discloses the scheme of adding a blade to the head of the intestine; [0005] 200720017706.4 and 200720017706.4 disclose the scheme of inden...

AI Technical Summary

Problems solved by technology

[0008] In the above scheme, setting traces and patches on the casing will increase the possibility of packaging air leakage, increase the cost of packaging materials, and the packaging material production line needs to be redesigned. Adding blades in the packaging will increase additional costs and waste, because PVDC adhesion is not good. And it is also very difficult to heat seal the sausage meat on the casing after filling

[0009] Since the appearance of the existing ham sausage packaging, the problem of convenient, cheap and reliable opening has not been effectively solved
