PACKAGING CONTAINER FOR HEATING IN MICROWAVE OVEN

摘要

PROBLEM TO BE SOLVED: To easily breathe out steam by providing an expected unsealing part for breathing out steam at the tip of a spout formed at an upper corner part. SOLUTION: A spout 8 projected sideways like a beak is provided at an upper corner. The front face sheet 2a and the rear face sheet 2b are extended sideways respectively to form the spout 8 and the external edges of the extended parts are stuck to the front face sheet and the rear face sheet to form a seal part 6. The seal part 6 at the projected part is formed to have a V-shape when viewing it from the front face. The tip 9 of the projected spout 8 is formed to position at the farther side than the position 10a of the external edge in the longitudinal direction of the container of the lower side 10 of the packaging container 1. An expected unsealing part 11 for breathing out steam is formed at the farther side than the position 10a at the front end side of the spout 8 to extend to the height direction of the container and indicated by printing so as to be easy to understand the cutting position.
