Appeal No. 95-2880
Application 08/091,294
knowledge to interlock the bead and groove to the extent
sufficient to seal against migration therethrough of the material
being dispensed, considering such factors as the dispensing
pressure and the viscosity of the material, to insure that the
dispenser is operative.
For the reasons expressed above, it is our conclusion that
the combined teachings of Colin, Yu and Yoshioka establish a
prima facie case of obviousness with regard to the subject matter
recited in claim 1. This rejection of claim 1 therefore is
sustained.
An alternative rejection of claim 1 is based upon Colin and
Yu, this time taken further in view of Schneider. Colin and Yu
were discussed above. Schneider discloses a squeeze-type
dispenser in which a rotatable spout is attached to the
dispensing end by means of an interlocking bead and groove.
According to the specification, "[t}his guarantees that the spout
is mounted . . . securely, sealed, and is capable of being turned
by 360E" (translation, page 7).
The analysis and conclusions expressed above with regard to
the rejection utilizing Yoshioka apply as well to Schneider, and
therefore we also will sustain this rejection of claim 1.
