  • Patent number: 6082567
    Abstract: A container, preferably of small capacity, such as a school milk plastic bottle, has a neck having an in-turned lip flange, a vertical surface spaced below the lip flange and an external shoulder below the vertical surface. A second external shoulder below the first-mentioned shoulder is preferably slanted upwardly-outwardly. A cap for the neck has a top and a skirt depending from the top formed with internal bead segments which snap under the first mentioned shoulder. The lower edge of the skirt fits tightly against the second shoulder to prevent the fingernails from being used to overcome the tamper-evident feature of the cap. A tear tab (preferably chevron-shaped in cross-section) depends from the skirt. An external, vertical scoreline adjoins the tab and at its upper end is adjacent a second scoreline which is formed on the interior of the top. Pulling the tab tears the skirt from the top for about 342.degree. of its circumference.

  • Patent number: 6003699
    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. The exterior of the neck is formed with shoulders which engage over locking beads 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.
