Container Neck Finish And Method And Apparatus For Forming Same And Cap For Use Thereon
Laszlo G. Sandor - Fremont CA Daniel Luch - Morgan Hill CA Richard E. Repp - San Jose CA
Assignee:
Portola Packaging, Inc. - San Jose CA
International Classification:
B65D 4148
US Classification:
215 43, 215 45, 215256, 215344, 264536, 425527
Abstract:
The neck of a container has a smooth seal surface engaged by the inner skirt or plug of a cap. Such surface is free of trim and parting line flaws which are characteristic of blow-molded jars because the surface is formed in such a way that the seal surface is not in contact with mold parting lines and further the trim (excess plastic) of the neck is located away from the sealing surface. In one form of the disclosure, above the sealing surface the neck wall slants outward and then bends upward-inward in a short, tapered stretch about 18 degree to the horizontal which engages the underside of the cap disk to compress against the disk or a liner or foil. Other forms of seal surfaces are disclosed In another form of the invention, above the seal surface the neck extends outward and then upward and then inward in a flange which is trimmed along a line which has a circumference no less than the circumference of the seal surface. The exterior of the neck is formed with shoulders or screw threads which engage over locking beads or threads on the interior of the outer skirt of the cap. Caps suitable for combination with the neck, methods of forming the neck and mold apparatus for forming the neck are also disclosed.

Assignee:
Portola Packaging, Inc. - San Jose CA
International Classification:
B65D 3900 B65D 4134
US Classification:
215256
Abstract:
A container neck is used with a tamper-evident, snap-on, screw-off closure. The neck has a multiple of four first helical threads on a neck stretch portion, and at least one external ratchet tooth on a locking wall portion below the neck stretch. The closure has an upper skirt having second helical threads mating with the first helical thread of the neck and a lower skirt with at least one internal ratchet tooth shaped and positioned to engage the external ratchet tooth when the closure is applied to the neck. The teeth formed on the skirt interior and neck exterior are arranged to provide at least one circumferentially extending stretch of the tamper-evident band where the teeth are not engaged. A line of weakness extending vertically through the disengaged stretch of the tamper-evident band is ruptured when the closure is unscrewed from the neck. The number of helical threads is preferably eight and, in any event, a multiple of four.

Brian M. Adams - Newark CA Rawson L. Chenault - San Francisco CA Laszlo G. Sandor - Fremont CA Daniel Luch - Morgan Hill CA
Assignee:
Portola Packaging, Inc - San Jose CA
International Classification:
B65D 2542
US Classification:
215 45
Abstract:
A fitment for use as a pour spout for a paper carton or flexible bag for liquids and powders has a flange which may be welded around a hole in the carton. A spout projecting outward from the flange is provided with a removable membrane integral with an inward projection positioned on the interior of the spout approximately midway of its height. Preferably the membrane is concave. A horizontally disposed pull ring is attached to the membrane by a connector so that pulling the ring removes the membrane by fracturing the tear line at the juncture of the outer edge of the membrane and the projection. A cap snaps over the spout and may be removed by unscrewing the complementary threads on cap and spout. A tamper-evidencing band frangibly connected to the lower edge of the cap skirt engages the exterior of the spout so that the cap cannot be removed without breaking the fragible connection.
