allegedly due to a molding manufacturing step; (2) a related problem with an
anchor band riding up the bottle neck during closure of the cap on the
container; (3) a leakage problem; (4) molding problems resulting from
complicated neck profile designs used in efforts to overcome the
aforementioned problems; and (5) bung deformation adjacent to the prong
that rendered an integral sealing bond ineffective (Davis col. 1, l. 42 – col. 2,
l. 21).
Davis teaches an intricate plastic container neck and closure assembly
design to address the above-noted problems. Davis provides a container
neck profile that includes:
a main external bead and an auxiliary external bead for co-
operation with a modified anchor band with an internal profile
for engagement with the beads. In addition, a primary internal
sealing bead is provided remote from the mouth of the
container and its accuracy is more easily controlled.
Davis at col. 2, ll. 26-32.
Specifically, Davis teaches that:
As shown in FIG. 3 the closure has a cap-retaining and
sealing internal projection 36 to fit under the snap-over bead 1
to hold the cap part in place. The closure also has a first
internal main projection 6 on the anchor band to fit under the
main band retaining bead 2 and a second auxiliary projection 7
on the anchor band to fit under the auxiliary bead 3. Reference
to Fig. 3 will show that the mouth or upper edge of the
container really plays no part in the sealing effected by the
closure.
