Abstract
Abstract A container for packaging semiconductor components is formed by a tube adapted to longitudinally contain a stack of components and having a body portion made of electrically conductive opaque plastic and a window portion made of electrically non-conductive transparent plastic. In this way EMI shielding is provided and visual inspection of the components is possible.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
88 words
A container for packaging a stack of electronic components requiring EMI shielding, said container comprising an elongated tube adapted to longitudinally contain the stack, said tube having a body portion made of electrically conductive opaque plastic so as to provide said shielding and a longitudinally extending windowpane portion made of electrically non-conductive transparent plastic so as to permit inspection of the components when in said tube, said body portion integrally forming electrically conductive plastic internal projections positioned so as to prevent said components from contacting said windowpane portion.
Claim 2
Dependent Claim
88 words
A container for packaging a stack of electronic components requiring EMI shielding, said container comprising an elongated tube adapted to longitudinally contain the stack, said tube having a body portion made of electrically conductive opaque plastic so as to provide said shielding and a longitudinally extending windowpane portion made of electrically non-conductive transparent plastic so as to permit inspection of the components when in said tube, said body portion integrally forming electrically conductive plastic internal projections positioned so as to prevent said components from contacting said windowpane portion.
Claim 3
Dependent Claim
44 words
The container of claim 1 in which said projections are in the form of longitudinally extending ribs positioned adjacent to the sides of said windowpane portion and extending inwardly so as to be contacted by said components if they move towards the windowpane portion.
Claim 4
Dependent Claim
49 words
The container of claim 2 in which the tube's said body portion integrally forms an internal longitudinally extending shelf spaced from and opposite to said windowpane portion and adapted to support said components, said shelf having rails on which said components can slide longitudinally with respect to said tube.
Claim 5
Dependent Claim
24 words
The container of claims 1, 2 or 3 in which the container tube is a coextrusion of the electrically conductive and electrically non-conductive plastics.
