Abstract
Abstract An impact-resistant wrapping system includes a sheetlike wrapping body having a cavity surrounded by a flexible wall member with gas-barrier properties and a gas-generating capsule having at least two types of materials for generating a gas to expand the cavity of the sheetlike wrapping body. The materials are separately sealed by a film and can be mixed with each other upon being depressed. A portion permeable only to the gas is formed in at least a part of the gas-generating capsule, while the gas-generating capsule is accommodated in the cavity of the sheetlike wrapping body.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
152 words
An impact-resistant wrapping system, comprising: a wrapping body comprising a flexible wall member that is substantially impermeable to gas and a cavity inside said flexible wall member; and a gas-generating capsule accommodated in said cavity of said wrapping body, said gas-generating capsule comprising at least two types of materials that are separately sealed therein and that are mixable with each other upon said gas-generating capsule being pressed, said at least two types of materials having the properties of generating a gas upon being mixed with each other, and said gas-generating capsule at least partly comprising a portion permeable to the gas generated by said two types of materials, whereby said cavity of said wrapping body can be inflated by the gas generated by pressing said gas-generating capsule so as to mix said at least two types of materials and the gas exiting said gas-generating capsule through said portion permeable to the gas.
Claim 2
Dependent Claim
152 words
An impact-resistant wrapping system, comprising: a wrapping body comprising a flexible wall member that is substantially impermeable to gas and a cavity inside said flexible wall member; and a gas-generating capsule accommodated in said cavity of said wrapping body, said gas-generating capsule comprising at least two types of materials that are separately sealed therein and that are mixable with each other upon said gas-generating capsule being pressed, said at least two types of materials having the properties of generating a gas upon being mixed with each other, and said gas-generating capsule at least partly comprising a portion permeable to the gas generated by said two types of materials, whereby said cavity of said wrapping body can be inflated by the gas generated by pressing said gas-generating capsule so as to mix said at least two types of materials and the gas exiting said gas-generating capsule through said portion permeable to the gas.
Claim 3
Dependent Claim
24 words
The system of claim 1, wherein said flexible wall member has inner surfaces opposite to each other that are partially adhered to each other.
Claim 4
Dependent Claim
32 words
The system of claim 1, wherein said cavity in said wrapping body is partitioned into a plurality of separate compartments, and each of said compartments has a said gas-generating capsule disposed therein.
Claim 5
Dependent Claim
55 words
The system of claim 1, wherein said wrapping body further comprises a second cavity inside said flexible wall member, the first said cavity and said second cavity being layered such that said cavities are stacked on top of each other inside said flexible wall member, each of said cavities having a said gas-generating capsule therein.
Claim 6
Dependent Claim
43 words
The system of claim 1, wherein said flexible wall member has an outer surface and said outer surface has a connecting means thereon for connecting portions of said flexible wall member together in order to hold said wrapping body in a desired shape.
Claim 7
Dependent Claim
18 words
The system of claim 1, wherein said cavity has an elastic impact resistant material compressed and accommodated therein.
Claim 8
Dependent Claim
34 words
The system of claim 1, and further comprising an exhaust valve mounted on said wrapping body and communicating with said cavity for exhausting the gas from said cavity to the outside of said cavity.
Claim 9
Dependent Claim
29 words
The system of claim 7 herein said exhaust valve further comprises means for reinjecting a gas into said cavity after said cavity has been exhausted and resealing said cavity.
Claim 10
Dependent Claim
24 words
The system of claim 1, wherein said gas-generating capsule is provided with means for preventing accidental pressing of said gas-generating capsule in said cavity.
Claim 11
Dependent Claim
35 words
The system of claim 1, wherein said gas-generating capsule is located at a predetermined position in said cavity, and said flexible wall member has indicia thereon corresponding to the predetermined position of said gas-generating position.
Claim 12
Dependent Claim
47 words
The system of claim 1, wherein said gas-generating capsule comprises one vessel half made of a hard material, another vessel half connected to said one vessel half and comprising said portion permeable to the gas, and a partition film separating said at least two types of materials.
