Title: Packaging bag
Inventor: YAMAMOTO TETSUHIRO
IPC: B65D30/08
Filed: 1992-05-15
Abstract: PURPOSE:To provide a packaging bag which is capable of being completely sealed, protected against a sudden breakage upon heating and produced at a low cost and which lends itself to the production by an automatic packaging machine. CONSTITUTION:The packaging bag 1 is made of a flexible packaging material 2 having a plurality of easily separable sealant layers 4 laminated on the inner surface of a base material 3 by heat sealing with the sealant layers 4 facing each other. The packaging bag 1 can be completely sealed with its contents therein and, upon heating, the sealant layers 4 separate from each other slowly to open the bag and, therefore, a sudden breakage of the bag can be prevented. This also produces the effect of suitably heating the contents with steam inside the bag until it opens. Thus, this packaging bag can be produced by the conventional automatic packaging machine at a low cost.

The displacement of the adhesive layer in the up-and-down direction generated at this time is sensed by the sensor 6 and the quantity of rotation in the rotary direction is similarly sensed by a gap sensor 8. Further, the load state of the adhesive layer is sensed by three triaxial measuring load cells 10. From the data of those sensors 6, 8 and cells 10, the material physical properties of the adhesive layer can be determined by the microcomputer 13.
