Appeal No. 96-4162
Application 08/313,901
Figure 2, the molding process of the invention uses a mold having at least three parts
including an end member (21) and a pair of side members (30 and 31). The inner surface
of the end member (21) is provided with a frusto-conical recess (25). The molded
container is thus free of “either axially oriented or transversely oriented parting lines on the
sealing surface itself” (specification, page 3). The process of the invention also includes
providing a transfer ring (12) and a closure engaging surface (16) on the container.
Claims 1 and 3 are representative and read as follows:
1. In the process of molding a container having a finish at an open end thereof in
which the end of the finish is provided with an end surface and a frusto-conical sealing
area thereon, including the steps of providing a mold having at least three parts including
an end member and a pair of side members forming the end and side surfaces of said
finish, said end and side members being positioned in abutted relation during a molding
operation; the additional step of: forming an axially extending recess in an inner surface of
said end member corresponding to the end surface and said frusto-conical sealing area
whereby all parting lines formed by said mold members during molding are positioned
outside said frusto-conical sealing area.
3. An improved mold for containers having a finish incorporating a frusto-conical
sealing surface on an outer surface thereof adjacent the end of said finish; said mold
comprising at least an axially displaceable end member having a recess therein enclosing
said frusto-conical sealing area, and a pair of laterally displaceable side members forming
the remaining outer surfaces of said finish.
The examiner has rejected claims 1 through 6 under the first paragraph of 35
U.S.C. § 112 as being based on a specification which fails to provide an enabling
disclosure of how to make and/or use the invention and under 35 U.S.C. § 101 as being
directed to an inoperative invention. Additionally, the examiner has rejected the claims as
