AI Technical Summary

Technical Problem

Existing food packaging for cheeses, such as those described in JP H07-101463, WO 2011/058237, FR 2957062, and FR 2880869 A1, suffer from leaks, leading to water evaporation, oxygen ingress, and mold formation, which affect product preservation and appearance, while also being complex and material-intensive to produce.

Method used

A packaging solution that forms a volume from a single sheet, allowing direct filling with hot food products, minimizing ambient exposure, and featuring a sealing system that maintains high production rates and hygiene, using materials like paper or cardboard with specific weakenings and seals to prevent leaks.

Benefits of technology

The solution provides effective sealing, reduces contamination risks, and maintains high production rates by forming a package that minimizes exposure to ambient air, improving preservation and appearance while being economical to produce.

Abstract

Food product package formed by a sheet (10) resulting from a blank (70) with a plurality of sheets, each sheet of the blank having weakened portions (30, 31, 32, 33, 42, 43, 44, 53, 45, 46, 47, 48, 49, 50, 51, 52, 53, 62, 63, 64, 65, 66), and a tongue (56) which is secured to a transverse edge (40) of the sheet, the sheet being folded along transverse weakened portions (42, 43, 44, 53, 66) in order to form a tube with a rectangular cross-section and being sealed on itself along a peelable or tearable transverse joint, the tongue (56) projecting longitudinally from the transverse joint, the sheet being sealed longitudinally along a longitudinal base joint, and the package being closed by longitudinally sealing the sheet on itself along a longitudinal top joint.
