Abstract
Abstract A process for obtaining a package containing at least two mutually reactive materials comprises the steps of introducing the reactive materials into an envelope suitable for vacuum packing, placing the reactive materials within said envelope in separate layers with at least one intervening separating layer of a material which is inert relative to the adjacent layer of a reactive material, evacuating and sealing the envelope.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
70 words
A process for providing a package containing at least two mutually reactive particulate materials, characterized in that it comprises the steps of introducing the reactive materials into an envelope suitable for vacuum packing, placing the reactive materials within said envelope in separate layers with at least one intervening separating layer of a material which is inert relative to the adjacent layer of a reactive material, evacuating and sealing the envelope.
Claim 2
Dependent Claim
70 words
A process for providing a package containing at least two mutually reactive particulate materials, characterized in that it comprises the steps of introducing the reactive materials into an envelope suitable for vacuum packing, placing the reactive materials within said envelope in separate layers with at least one intervening separating layer of a material which is inert relative to the adjacent layer of a reactive material, evacuating and sealing the envelope.
Claim 3
Dependent Claim
28 words
A process according to claim 1, characterized in providing between the reactive materials a single separating layer of a material which is inert relative to both reactive materials.
Claim 4
Dependent Claim
27 words
A process according to claim 1, characterized in providing between the layers of the reactive materials at least two separating layers of materials which are mutually inert.
Claim 5
Dependent Claim
43 words
A package comprising a sealed envelope comprising separate layers of at least two mutually reactive materials separated by at least one layer of a material which is inert relative to the material of the adjacent layer, the pressure within said envelope being subatmospheric.
Claim 6
Dependent Claim
43 words
A package comprising a sealed envelope comprising separate layers of at least two mutually reactive materials separated by at least one layer of a material which is inert relative to the material of the adjacent layer, the pressure within said envelope being subatmospheric.
