Abstract
The present invention is concerned with flexible cooking containers which the user can fill with selected foodstuff and then seal same prior to inserting in the microwave oven for preferably cooking the contents at greater than atmospheric pressure for improved health/hygiene reasons and for improved taste and flavour. The user can thus select the nature of the foodstuffs which are to be cooked.
Claims15
A cooking container in the form of a bag or pouch, formed of plastics film material with the bottom and sides of the container being sealed together or closed and the top or upper portion thereof being provided with sealing means for enabling sealing of the container after foodstuffs have been inserted into the container body, such sealing means being adapted to or being such as to remain sealed when the product is cooked, such container containing venting means to enable the pressure within the container to be controlled when cooking takes place.
A pouch or bag of flexible plastics material for enabling food to be cooked therein under pressure having an access opening or mouth closable by means of a releasable sealing or closure means in the form of a press-fit bead-and-groove or rib-and-channel closure means wherein the projection portion is on a first strip of plastics material secured along its length to an inner surface of one side of the bag wall, and the groove or channel forming portion is formed on a second strip of plastics material secured along its length to an inner surface of a second and opposite side of the bag wall, one said strip portion being secured so as to leave a freely extending portion carrying the bead or the groove, and presenting, when the closure is closed, a surface opposite to that where the bead or groove is formed such as to present said surface exposed to steam and other pressure during cooking the contents of the bag as to urge the bead and groove portions together to maintain the seal.
A bag or pouch for enabling food to be cooked therein, formed of film or sheet plastics material and having an access opening provided with releasable and re-sealable closure or sealing means for enabling sealing of the container after foodstuffs have been inserted, said closure or sealing means being adapted to or being such as to enable steam and/or other pressure within the bag to act to urge the two parts of the closure/sealing means together to assist in the bag remaining sealed when the product is cooked, such container containing venting means to enable the pressure within the container to be controlled when cooking takes place.
A pouch or bag of flexible plastics material for enabling food to be cooked therein under pressure having an access opening or mouth closable by means of a releasable sealing or closure means in the form of a press-fit bead-and-groove or rib-and-channel closure means wherein the projection portion is on a first strip of plastics material secured along its length to an inner surface of one side of the bag wall, and the groove or channel forming portion is formed on a second strip of plastics material secured along its length to an inner surface of a second and opposite side of the bag wall, one strip portion being secured so as to leave a freely extending flap portion carrying the bead or the groove presenting when the closure is closed a surface remote from that where the bead or groove is formed such as to present said surface exposed to steam and other pressure during cooking the contents of the bag as to cover the bead and groove portions and/or to urge the press fitter bead and groove potions together to maintain the seal.
