Abstract
Abstract To provide improved protection for a fragile or delicate article in the event that an inflated packaging structure in which the article is disposed for transportation is punctured there is provided a light weight, simple and inexpensive inflatable packaging structure in which an inflatable inner liner attached within an outer envelope comprises two inflatable zones each incorporating a plurality of inflatable cells, with the cells of one of the zones alternating with the cells of the other zone. Thus, with the inner liner inflated and the fragile or delicate article disposed between two superposed layers of the liner the article is still substantially protected by the inflated cells of one of the zones even if the other zone is punctured.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
121 words
An inflatable packaging structure comprising an envelope, and an inner liner disposed within the envelope, the inner liner comprising first and second superposed inflatable layers between which an article to be packaged is adapted to be disposed and each of which comprises two inflatable zones each incorporating a plurality of inflatable cells with the cells of one of the inflatable zones alternating with the cells of the other inflatable zone, a barrier of serpentine configuration separating the two inflatable zones of each inflatable layer and defining said alternating cells of said two inflatable zones, and closable valve means communicating with the zones for admission thereto of pressurized gaseous fluid to inflate the inflatable zones of the first and second inflatable layers.
Claim 2
Dependent Claim
121 words
An inflatable packaging structure comprising an envelope, and an inner liner disposed within the envelope, the inner liner comprising first and second superposed inflatable layers between which an article to be packaged is adapted to be disposed and each of which comprises two inflatable zones each incorporating a plurality of inflatable cells with the cells of one of the inflatable zones alternating with the cells of the other inflatable zone, a barrier of serpentine configuration separating the two inflatable zones of each inflatable layer and defining said alternating cells of said two inflatable zones, and closable valve means communicating with the zones for admission thereto of pressurized gaseous fluid to inflate the inflatable zones of the first and second inflatable layers.
Claim 3
Dependent Claim
25 words
an inflatable packaging structure according to claim 1, wherein the first and second inflatable layers each comprise two superposed portions of flexible sheet plastics material.
Claim 4
Dependent Claim
50 words
An inflatable packaging structure according to claim 1, wherein said first and second inflatable layers comprise a single inflatable layer folded upon itself, each inflatable zone of said first inflatable layer being in communication across the fold with a respective one of the inflatable zones of the second inflatable layer.
Claim 5
Dependent Claim
30 words
An inflatable packaging structure according to claim 3, wherein portions of the barrier of serpentine configuration are transversely disposed, said fold extending along one of said portions of the barrier.
Claim 6
Dependent Claim
46 words
An inflatable packaging structure according to claim 3, wherein each of said first and second inflatable layers has opposed side edges, with the side edges of the first inflatable layer each being secured to a respective one of the side edges of the second inflatable layer.
Claim 7
Dependent Claim
31 words
An inflatable packaging structure according to claim 3, wherein the valve means comprises a single valve in communication with each of the inflatable zones of the first and second inflatable layers.
Claim 8
Dependent Claim
76 words
An inflatable packaging structure according to claim 6, wherein the valve means is of flexible material and has a bifurcated outlet end portion the limbs of which are each in communication with a respective one of the inflatable zones of the first and second inflatable layers thereby to provide said communication with each of said inflatable zones, the limbs being collapsible to close the valve means by pressure of pressurized fluid within the respective inflatable zones.
Claim 9
Dependent Claim
17 words
An inflatable packaging structure according to claim 1, wherein the inner liner is attached to the envelope.
Claim 10
Dependent Claim
38 words
An inflatable packaging structure according to claim 8, wherein the envelope has a closed end and an opposed closable end, said attachment of the inner liner to the envelope being at or adjacent to said closed end thereof.
