Abstract: A metal gasket is composed of a plurality of metal sheets superimposed one above the other and including a plurality of joints. Each of the joints includes a plurality of cut lines defining inner side edges of the metal sheets, and a bent portion located between the cut lines and having outer side edges which are frictionally engaged with the inner side edges of the metal sheets. The joints are oriented in different directions to accommodate a shear force.

Abstract: A container from which its contents can be readily taken out by a simple one-hand finger operation, is provided. The container comprises a lid and a container main body and is sealed at least at its peripheral flange. The container main body can be bent outwardly, and it comprises two contents-holding portions which are divided by the portion for bending and which are designed such that when the container main body is bent these two portions may be pressed by each other. The lid comprises at least a monoaxially oriented film. The lengthwise direction of the portion for bending coincides with the direction of orientation of the monoaxially oriented film. A non-sealed portion is provided at an edge portion of the peripheral flange coincident with at least one end of the portion for bending, and at least two slit lines for initiating tear are provided in a part of the lid which constitutes the non-sealed portion.

Abstract: The apparatus for sealing the heads of containers with a biaxially oriented plastic film comprises a horizontal conveyor for conveying the containers to be sealed, and a horizontal endless belt disposed above the conveyor in parallel thereto and including a lower traveling portion adapted to be driven in the same direction as the conveyor at a speed equal to the speed of the conveyor.

Abstract: The apparatus for sealing the heads of containers comprises means for cutting out from a continuous plastic film a sealing sheet, means for folding the peripheral portion of the sealing sheet toward the outer peripheral surface of the container and means for applying hot air against the folded peripheral portion of the sheet to heat-shrink the same.
