Abstract
Abstract A container for delicate articles which includes an inner envelope, and an inflatable outer envelope sealed to the ends thereof. The inner envelope is vented to the exterior of the container so that, on inflation of the outer envelope, the inner envelope is collapsed tightly about the article, which is thus suspended in and protected by the inflated outer envelope. Preferably, the inflation is accomplished within an outer protective casing, which is coated on its interior with an adhesive. Should the casing and outer envelope be punctured, the parts will then still be kept in essentially established positions.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
112 words
A container for fragile articles comprising an outer envelope of flexible sheet material, an elongated inner envelope of flexible sheet material for receiving an article, extending across said outer envelope, said outer envelope having normal dimensions in all directions greater than said inner envelope, the walls of said outer envelope being sealed to said inner envelope only adjacent each end of the latter, the interior of said inner envelope being vented to the atmosphere outside said outer envelope, and means for inflating said entire outer envelope, thereby expelling air from said inner envelope and collapsing said inner envelope tightly about said article, said outer envelope being empty except for said inner envelope.
Claim 2
Dependent Claim
112 words
A container for fragile articles comprising an outer envelope of flexible sheet material, an elongated inner envelope of flexible sheet material for receiving an article, extending across said outer envelope, said outer envelope having normal dimensions in all directions greater than said inner envelope, the walls of said outer envelope being sealed to said inner envelope only adjacent each end of the latter, the interior of said inner envelope being vented to the atmosphere outside said outer envelope, and means for inflating said entire outer envelope, thereby expelling air from said inner envelope and collapsing said inner envelope tightly about said article, said outer envelope being empty except for said inner envelope.
Claim 3
Dependent Claim
39 words
A container as defined in claim 1 and further comprising a substantially rigid casing surrounding and in contact with said outer envelope over a substantial portion of the surface of the latter and adhesively joined to said outer envelope.
Claim 4
Dependent Claim
145 words
A container for fragile articles comprising an outer envelope of flexible sheet material, an elongated inner envelope of flexible sheet material for receiving an article, extending across said outer envelope, said outer envelope having normal dimensions in all directions greater than said inner envelope, the walls of said outer envelope being sealed to said inner envelope only adjacent each end of the latter, the interior of said inner envelope being vented to the atmosphere outside said outer envelope, an intermediate envelope within said outer envelope and surrounding said inner envelope, said intermediate envelope being sealed to said outer and inner envelopes, means for introducing liquid into said intermediate envelope, and means for inflating said entire outer envelope, thereby expelling air from said inner envelope and collapsing said inner envelope tightly about said article, said outer envelope being empty except for said inner and intermediate envelopes.
Claim 5
Dependent Claim
145 words
A container for fragile articles comprising an outer envelope of flexible sheet material, an elongated inner envelope of flexible sheet material for receiving an article, extending across said outer envelope, said outer envelope having normal dimensions in all directions greater than said inner envelope, the walls of said outer envelope being sealed to said inner envelope only adjacent each end of the latter, the interior of said inner envelope being vented to the atmosphere outside said outer envelope, an intermediate envelope within said outer envelope and surrounding said inner envelope, said intermediate envelope being sealed to said outer and inner envelopes, means for introducing liquid into said intermediate envelope, and means for inflating said entire outer envelope, thereby expelling air from said inner envelope and collapsing said inner envelope tightly about said article, said outer envelope being empty except for said inner and intermediate envelopes.
Claim 6
Dependent Claim
57 words
A container as defined in claim 1 wherein said inner envelope is open at one end to provide a vent to the atmosphere and permit insertion of the article to be packaged and is sealed at a point within said outer envelope spaced from both ends of said inner envelope, to position the article to be packaged.
Claim 7
Independent Claim
124 words
A method of packaging an article comprising: (a) providing a container comprising an outer envelope of flexible sheet material and an elongated inner envelope of flexible sheet material, within and extending across said outer envelope, said outer envelope having normal dimensions in all directions greater than said inner envelope, said outer envelope being sealed to said inner envelope solely adjacent the ends of the latter, said inner envelope being open at at least one end, said outer envelope being empty except for said inner envelope; (b) inserting said article into said inner envelope; and (c) inflating said entire outer envelope while said inner envelope is open to the atmosphere, thereby expelling air from said inner envelope and collapsing said inner envelope about said article.
Claim 8
Independent Claim
124 words
A method of packaging an article comprising: (a) providing a container comprising an outer envelope of flexible sheet material and an elongated inner envelope of flexible sheet material, within and extending across said outer envelope, said outer envelope having normal dimensions in all directions greater than said inner envelope, said outer envelope being sealed to said inner envelope solely adjacent the ends of the latter, said inner envelope being open at at least one end, said outer envelope being empty except for said inner envelope; (b) inserting said article into said inner envelope; and (c) inflating said entire outer envelope while said inner envelope is open to the atmosphere, thereby expelling air from said inner envelope and collapsing said inner envelope about said article.
Claim 9
Dependent Claim
21 words
A method as defined in claim 5 wherein said outer envelope is adhesively secured to a surrounding substantially rigid protective casing.
Claim 10
Dependent Claim
35 words
A method as defined in claim 6 comprising inserting said container in a casing coated on the inside with a contact adhesive prior to inflation and inflating said outer envelope into contact with said casing.
Claim 11
Dependent Claim
19 words
A method as defined in claim 6 and further comprising sealing said inner envelope after inflating said outer envelope.
