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.

A container for fragile articles, comprising: an outer container body of flexible material composed only of first and second, forward and rear, walls constituting the outer walls of the container, the walls being sealingly connected directly to each other at the bottom and at the side margins of the container and open at the upper end of the container; and an inner container body of flexible material composed only of first and second, forward and rear, walls sealingly connected directly to each other at the bottom and at the side margins and open at the upper margins to provide a storage compartment for reception of articles to be protected; the side margins of the inner container body being sealingly connected directly to the side margins of the outer container body; the upper margins of the forward and rear walls of the inner container body being sealingly connected to the upper portions of the respective forward and rear walls of the outer container body below the top of the outer container body; and the bottom margin of the inner container body being sealingly connected to at least one of the outer walls of the container; and fastener means on the upper portions of the outer walls of the container to hold the free ends in adjacency; the inner and outer container bodies cooperating to define a first inflation chamber between the inner container body and a first wall of the outer container body and a second inflation chamber between the inner container body and the second wall of the outer container body, with the inner container body serving as a partition to prevent flow of air between the two chambers; and a valved air flow port in each outer wall for independent inflation of each of the chambers; the chambers being inflatable to form air cushions pressing toward each other to force the major portion of the air out of the storage compartment and cause its walls to conform to and grip a stored article.
