Abstract
A sealed airtight container and a method for forming the same produces an increased resistance between the seal and a flange on the container to pressure differences between the inside of the container and the outside environment. The container includes a body having a hollow interior with sidewalls, a bottom, and having a planar opening at one end. The opening in the hollow interior is surrounded by an outwardly extending flange. A multi-layer peelable cover is sealed to the flange surrounding the opening. The cover and the flange are deformed towards the bottom of the container from the plane of the opening to be sealed.
Claims12
A method for forming a sealed airtight box-like hollow container having an opening extending in a plane at a top thereof, sidewalls, a bottom and having a peelable cover over said top planar opening, said container having increased resistance between the container and the outside environment comprising the steps of:
- forming a container having an outwardly extending flange around the top planar opening of the container and parallel thereto;
- heat sealing a multi-layer peelable cover to said flange;
- and
- deforming said sealed cover and said flange at an angle toward said bottom with respect to said plane of said top planar opening.
A container comprising:
- a plastic body having a hollow interior with sidewalls, a bottom, and having a planar opening extending in a plane at a top thereof, said plank opening at said top surrounded by an outwardly extending flange and
- a multi-layer peelable cover sealed to said flange surrounding said top planar opening, said cover and said flange after deformation extending permanently at an angle towards said bottom with respect to said plane of said planar opening.
A method for forming a sealed airtight box-like hollow container having an opening extending in a plane at a top thereof sidewalls, a bottom and having a peelable cover over said top planar opening, said container having increased resistance between the inside of the container and the outside environment comprising the steps of:
- forming a container having a flange extending around the top planar opening and parallel thereto;
- and
- simultaneously heat sealing a multi-layer peelable cover to said flange and deforming said cover and said flange at an angle toward said bottom with respect to said plane of said top planar opening.
