Abstract

A one-way valve for a food package having a venting opening is provided. The one-way valve (100) is arranged to open in response to a release of excess steam (144) from within the food package (110), and comprises a membrane (102) comprising a sealing portion (104) and a barrier portion (106). The sealing portion (104) is arranged to be attached to the food package (110) to cover the venting opening (118) and to form a sealing interface (120) between the membrane (102) and the food package (110) such that the food package (110) is sealed. The barrier portion (106) is arranged at a periphery (122) of the membrane (102). A valve outlet (124) is arranged at a distal end (122) of the sealing portion (104) thereby spatially separated from the venting opening (118) when the membrane (102) is attached to the food package (110). The valve outlet (124) is arranged between the sealing portion (104) and the barrier portion (106). The sealing interface (120) is arranged such that a channel (142) is formed between the food package (110) and the membrane (102) when the release of excess steam (144) from within the food package (110) exceeds a threshold value. The channel (142) extends from the venting opening (118) to the valve outlet (124) such that a flow (146) of excess steam (144) from within the food package (110) is channeled to the valve outlet (124).

The second adhesive is arranged on each of two intermediate portions between each lateral edge portion and the center portion. The two intermediate portions extend from the first longitudinal edge to the opposite second longitudinal edge of the overlapping surface area. Moreover, a bond strength of the second adhesive is stronger than that of the first adhesive. The first membrane further comprises an opening such that a canal is formed between the first membrane and the second membrane when the one-way valve is mounted over the aperture of the food package and a gas pressure inside the food package exceeds a threshold value.

Abstract

A method is provided to present a cost- and environmentally-efficient method of pasteurizing and vacuum packing food, comprising the steps of providing a tray (1) with a first separating barrier (11) which divides the tray (1) into a first compartment (4) and a second compartment (5). Both the first compartment (4) and the second compartment (5) each have a flexible bottom, e.g. a first flexible bottom (6) and a second flexible bottom (7). The barrier (11) is formed such that it has a first channel (12) which connects the first compartment (4), which has a valve (16), with the second compartment (5). The contents inside each compartment is pasteurized and cooled, whereby a vacuum is created in the package (15) in such a manner that the flexible bottoms (6, 7) are caused to be concave relative the first compartment (4) and the second compartment (5) respectively. The result is a more hygienic and easier to prepare ready-to-eat meal with several compartments for different servings, having only one valve. Moreover, a package (15) is provided to be used in the implementation of said method.

Abstract

The invention relates to a system and package for food products which comprises a tray and a cover film which comprises an opening for venting of gas at overpressure that arises when cooking a food product contained in the package during supply of microwaves at a power P, wherein the opening has an opening area A adapted such that the ratio between the opening area and the supplied effect is in the range of 0,005 and 0,06mm2/W, preferably between 0,01 and 0,03 mm2/W, more preferably between 0,015 and 0,025 mm2/W, so that the opening has a sufficiently large opening area A that it allows a sufficient flow of gas during cooking to avoid that the package breaks due to overpressure, and so that the opening area A is sufficiently small to maintain an overpressure in the package during a time period after the supply of microwave power has ceased, which time period allows the package to be sealed in a subsequent processing step. Further there is described a method for packaging of food products.
