Title:
多層材料の周辺シールおよび包封継ぎ目
Document Type and Number:
Japanese Patent JP4065033
Kind Code:
B2
Abstract:
A container is provided having first and second side walls. The first side wall comprises first and second layers with the second layer overlapping a portion of the first layer to define an overlap area. A sealing flange extends from the first layer outward of the overlap area and the second side wall is connected to the first side wall along the sealing flange to define an inner chamber therebetween. The second side wall and the sealing flange define a first layered structure comprising a plurality of layers along the sealing flange. The overlap area and the second side wall define a second layered structure that has more layers than the first layered structure. The container is sealed by positioning peripheral edges of the first and second side walls into registration so that the overlap area is centrally disposed over the second side wall. Sealing energy is then applied to the first layered structure to define a peripheral seam.
