Appeal No. 97-4049
Application 08/456,802
A joint tab as 52 need not always be used and indeed the end closure
flaps may be secured by a tape or they may be secured by a tuck-in flap [column
4, line 53 through column 5, line 10].
As conceded by the examiner (see page 4 in the answer), the Ohlbach carton does
not meet the limitations in independent claims 1 and 20 pertaining to the electrically
conductive tape on the inner surface of the packaging member or packing container.
Although the Ohlbach reference teaches that the end closure flaps of the carton may be
secured by a tape, it does not indicate that this tape is or should be electrically conductive.
Holley discloses an electrostatic-dissipating packaging tape composed of a
transparent polymeric substrate, a transparent adhesive layer on one surface of the
14
substrate and a transparent clay coating having a surface resistivity of 10 ohms per
square or less on the opposite surface of the substrate. Figure 2 shows a typical use of
the tape wherein it serves as a cover or closure member for a packaging structure
containing electronic components which are sensitive to static electricity.
The Electronic Circuit Part Application Manual discloses the use of metallic foil as
an external shield to reflect electromagnetic energy.
