Definitions

  • the invention concerns a device for the packaging and preparation of food.
  • a device for the packaging and preparation of food.
  • Such a device is known from EP 0971849.
  • This known device particularly suitable for use in a microwave oven, comprises a plastic container, closed at the topside by means of a film sealed onto the container. In the film a part is made which functions as a valve. During heating of food present m the container, a vapour pressure will develop in the container, by means of which the pressure within the container will rise to above atmospheric pressure.
  • valve can become clogged up with food, as a result of which no vapour or at any rate only a limited amount of vapour can escape.
  • a further disadvantage is that the device has to be opened by the user rather quickly after heating since otherwise the device will be compressed together because of the pressure differences. When opening the container the risk exists that the user thereby gets into contact with the hot vapour which is still present.
  • This sticker should be removed by the user before heating. Disadvantage of it is that no quick pressure build-up takes place in the device and the user firstly has to manipulate the device before use.
  • a device o fe the advantage that the layers of film can be fastened in an easy manner, whereby during use a desired overpressure in the packaging can be obtained automatically and can be maintained,
  • Vapour will only be able to escape when a certain, increased vapour pressure has been obtained Because no valves are necessary, the above mentioned disadvantages are prevented " 1 he films can be fed in together when producing the dev ice and fastened onto the container, for example as a pre-formed laminate, but can also be fed in separately from each other The films can easily be fed in from a roll and be cut to size, by which also various sizes of containers can be applied easily. Moreover, in this way always a suitable combination of films and containers can be chosen, for example depending on the food to be packaged and prepared. Preparation should be understood in this context as at least preparing for consumption, including heating.
  • a device according to the invention is characterised by the measures according to claim 3.
  • the advantage is obtained that pressure can build up relatively fast between the bottom and the mentioned gastight and liquid tight film, whereby moreover also a fast build up of pressure to the desired level in the container is achieved.
  • multiple perforated films are envisaged, whereby in the direction away from the bottom layer the film or each film located above it has perforations with a total permeability surface which is smaller than that of the bottom film.
  • a device according to the invention is characterised by the measures according to claim 5.
  • Such a device vapour, entrapped between the two films can escape because the second film comes loose, at any rate partly, when the pressure between the films surpasses a certain increased preselected pressure.
  • Such a device can be manufactured particularly easy, while an automatic action is achieved immediately, whereby allowable overpressures can be set easily by the choice of the mentioned connections.
  • the film or each second film is implemented such that it tears when a certain pressure is surpassed to allow the release of the overpressure.
  • Use of a closed, gastight and liquid tight film above the perforated bottom film for a device according to the invention offers the advantage that in a closed condition it is prevented that moisture can leak away to the outside through the perforations, while moreover an airtight sealing can be obtained.
  • a modified atmosphere can be created within the container prior to or during packaging, for example for the preservation of packaged food
  • the gas in such an atmosphere can only escape when the films separate from each other or at any rate partly separate
  • the perforations in the bottom film are relatively small, for example round with a diameter between 50 and 5000 ⁇ m, preferably between 100 and 750 ⁇ m or openings with a different shape but with a comparable surface
  • a dimension between 200 and 500 ⁇ m is particularly suitable
  • a favourable flow-through resistance for vapour is obtained with it, while such perforations can be manufactured relatively accurate
  • the bottom film preferably is manufactured from a thermic stable laminate, particularly a laminate manufactured from polyester and polypropylene
  • the bottom film or each film placed above the bottom film thereby preferably is a heat-sealable plastic film, particularly polyester, which can be peeled off
  • a heat-sealable plastic film particularly polyester, which can be peeled off
  • other film materials consisting of one or more layers could be chosen, depending on the application, which choice will be immediately obvious for a skilled worker
  • the invention further concerns a method for the manufacture of a device for the packaging and preparation of food, characterised bv the measures according to claim 10
  • Such a method offers the advantage that a packaging can be manufactured in a particularly quick and easy manner in which food can be packaged, transported and prepared
  • various films put on top of each other can be fed in, for example as a laminate, prior to the joining thereof with the container, while the films furthermore can be fed in separately from each other
  • the films for example, can be fed m from a roll and directly be cut to size prior to or during the positioning In this way a particularly great freedom of design can be obtained, whereby packaging of various sizes can be manufactured in an easy way
  • the invention further concerns a method for the preparation of food, characterised by the measures according to claim 13
  • the advantage is achieved that packaged food can be put directly into an oven, particularly a microwave oven or steam oven, in which the food can be heated and prepared quickly, without the quality of it being influenced negatively
  • the quality of the food is retained in a particularly favourable manner
  • the packaged food for example, is drying out or is losing texture, colour, aromas or such, or at any rate that these qualities are influenced in an undesired way
  • vitamins are retained this manner
  • the invention further concerns an assembly of at least two layers of film for the closing of food containers, characterised by the measures according to claim 14
