Appeal 2007-0343
Application 09/745,702
Hamilton discloses the coating of flexible films with pressure
sensitive adhesive for releasable sealing to a target surface, the flexible films
having protrusions formed on an adhesive side which act to space a pressure
sensitive adhesive from a target surface until the film is pressed against the
target surface (Hamilton, col. 1, ll. 6-16; col. 3, ll. 51-61).
With respect to the shape of the passageway 25 and inlet and outlet
openings 23 and 24, Appellants' Specification teaches:
The cross-sectional shape of the passageway 25, or
the shape of either or both the inlet opening 23 and
outlet opening 24, can be circular, or can be
preferably oval or elliptical. It has been found that
an outlet opening and at least a portion of the
passageway that are oval or elliptical can
accommodate the human hand more readily than a
circular shape. The passageway can be cylindrical,
wherein the axis along the passageway is a straight
line, or elbowed, wherein the axis along the
passageway is curved or non-linear. The selection
of the shape and orientation of the passageway and
openings can depend on design and aesthetic
considerations of the use of the device.
(Specification 3:31 to 4:4.)
DISCUSSION
Richards' teaching that a cutter for severing the topmost package from
the remainder of the flexible tubing can be provided beneath the pack
location, and thus adjacent the outlet opening of the core 1 of said pack,
satisfies the limitation in claims 1 and 10 of a cutting blade positioned
adjacent the outlet opening of the inner core.
We also conclude that the combined teachings of Richards, Meissner
and Hamilton are sufficient to establish that it would have been obvious to
