发明名称 PROCESS FOR FORMING A THERMOPLASTIC BAG
摘要 A disposable or reusable and reclosable microwave-compatible thermoplastic bag (10) capable of being compactly stored as a food container in freezers, yet capable of standing with an upright spout in a microwave oven for non-spill thawing and cooking of food (27) contained in the bag (10). The bag (10) is formed of two wing-shaped pouches (12, 14) on either side of the upright spout, which is smaller than the pouches (12, 14). A preferred closure of a zipper type is provided in the spout which is adapted to automatically open to vent vapours from the bag upon softening of its thermoplastic structure during the cooking stage. A second aspect is a package for use as a cold storage and cooking utensil, comprising a thermoplastic bag (10) and a food product (27) therein. The bag (10) is formed of two wing-shaped pouches (12, 14) on either side of a spout, the spout forming the only exit for the food product (27) from the bag (10), whereby spilling of the food product (27) from the bag (10) is avoided during heating.
