Containers for cooking foodstuffs

摘要

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 flavor. The user can thus select the nature of the foodstuffs which are to be cooked.

主权项

1. A cooking container comprising:
a bag or pouch, formed of plastics film material with the bottom and sides of the container being sealed together or closed; a top or upper portion of the bag or pouch forming an initially-provided access opening; and a releasable seal on the bag or pouch for enabling sealing of the container after foodstuffs have been inserted into the container body through the access opening, such releasable seal being adapted to or being such as to remain sealed when the product is cooked; wherein the releasable seal includes a first strip of plastic material and a second strip of plastic material, said first and second strips being secured along their length on opposite inner sides of the bag, with the first strip having a bead or groove and the second strip having a free end flexible extension strip or flap extending from a section of the second strip along its length; wherein the flexible extension strip or flap of the second strip extends away from an interior of the bag or pouch and a groove or bead of the second strip facing away from the bead or groove of the first strip when not folded and, when folded, the flexible extension strip or flap of the second strip has a fold that includes a folded over portion with the groove or bead facing the bead or groove of the first strip such that the releasable seal is formed when the bead or groove of the first strip is pressed by press-fit against the groove or bead of the folded over portion on the second strip, and wherein the fold in the flexible extension strip or flap, which is located between the section of the second strip and the groove or bead of the flexible extension strip or flap, extends beyond the bead and groove and closer to the access opening than the groove or bead of the flexible extension strip or flap such that when the pressure increases inside the container when cooking takes place, the pressure exerts a force on an interior surface of the folded over portion of the flexible extension strip or flap and urges together the bead and groove of the seal formed by the first and second strips, wherein the sides of the container extend beyond the fold in the flexible extension strip or flap towards the access opening.
