Abstract

The total container comprises inner and outer container bodies, each closed at the bottom and sides and open at the top. The side margins of the inner container body are sealingly connected to the side margins of the outer container body, and the bottom margin of the container body is sealingly connected to at least one wall of the outer container body. The bottom of the compartment within the inner container body is a substantial distance above the bottom of the outer container body. The upper margins of the inner container body are sealingly connected to upper portions of the walls of the outer container body, so that the inner container body serves as a partition between first and second inflation chambers having valved air flow ports. The upper end of the outer container body may be wrapped up into a spiral formation to seal the compartment and the container as a whole. An article is placed in the compartment, the open end is sealed, and the chambers are inflated, forcing excess air out of the compartment through an outlet port. The stored article is suspended within the compartment, gripped by its walls and spaced from all of the outer parts of the container, which protects it from mechanical shock and moisture. The sealing of the container may be improved by including a resiliently yieldable filler strip within the spiral formation to increase its bulk and hence the sealing pressure.
