Abstract

A molding apparatus for molding a closure device for a container. The closure device may be tethered to the container, and may open and close via a hinged articulation. The closure device includes a cylindrical body comprising hinge-connecting areas with pockets formed in the interior wall and defining an inner surface of the hinge-connecting areas, and hinges extending downwardly from the hinge-connecting areas and positioned at or below a bottom edge of the cylindrical body. The molding apparatus comprises a cavity insert component and a core component that cooperate to form mold surfaces to mold the closure device such that hinges are located below the cap area of the closure device, and hinge-connecting areas formed by projections in the core mold component and recesses in the cavity mold component are located within the cap area are flanked by membranous areas.

First claim

1 . A closure device for a beverage container comprising:
a substantially cylindrical body with a closed end and an open end; a central protrusion extending radially outwardly from a bottom edge of the cylindrical body; a first hinge-connecting area and a second hinge-connecting area flanking the central protrusion on either side thereof; a first pocket formed in the interior wall of the cylindrical body defining an inner surface of the first hinge-connecting area; a second pocket ( 52 ) formed in the interior wall of the cylindrical body defining an inner surface of the second hinge-connecting area; a first hinge extending downwardly from the first hinge-connecting area, the first hinge positioned at or below the bottom edge of the cylindrical body; a second hinge extending downwardly from the second hinge-connecting area, the second hinge positioned at or below the bottom edge of the cylindrical body; a first leash connected to the bottom of the first hinge at a first end and to a tamper band at a second end; a second leash connected to the bottom of the second hinge at a first end and to the tamper band at a second end; the tamper band ( 16 ) further connected to the bottom edge ( 48 ) of the cylindrical body via frangible connections.

2 . The closure device of claim 1 , further comprising:
a first membranous area adjacent the first hinge-connecting area distally from the central protrusion.

3 . The closure device of claim 2 , further comprising:
a second membranous area adjacent the second hinge-connecting area distally from the central protrusion.

4 . The closure device of claim 3 , further comprising:
a third membranous area between the central protrusion and the first hinge-connecting area.

5 . The closure device of claim 4 , further comprising:
a fourth membranous area between the central protrusion and the second hinge-connecting area.

6 . The closure device of claim 2 , further comprising:
the first pocket formed in the interior wall of the cylindrical body also defining an inner surface of the first membranous area.

7 . The closure device of claim 3 , further comprising:
the second pocket formed in the interior wall of the cylindrical body also defining an inner surface of the second membranous area.

8 . The closure device of claim 4 , further comprising:
the first pocket formed in the interior wall of the cylindrical body also defining an inner surface of the third membranous area.

9 . The closure device of claim 5 , further comprising:
the second pocket formed in the interior wall of the cylindrical body also defining an inner surface of the fourth membranous area.

10 . The closure device of claim 1 , further comprising:
a first longitudinal groove defined in the first hinge at or below the bottom edge of the cylindrical body.

11 . The closure device of claim 10 , further comprising:
a second longitudinal groove defined in the second hinge at or below the bottom edge of the cylindrical body.

12 . A molding apparatus for molding a closure device for a container, comprising:
a cavity mold component; and a core mold component; wherein the cavity mold component and the core mold component cooperate to form a molding cavity for molding a closure device having hinges at or below a lower edge of a cap body connected to hinge-connecting areas on the lower edge of the cap body; the core mold component comprising projections proximate the area within the molding cavity for forming the hinge-connecting areas of the closure device during the molding process.

13 . The molding apparatus of claim 12 , further comprising:
the cavity mold component comprising recesses positioned proximate the projections for forming the hinge-connecting areas of the closure device during the molding process.

14 . The molding apparatus of claim 13 , further comprising:
the cavity mold component comprising a recess positioned between the recesses for forming a central protrusion on the closure device during the molding process.

15 . The molding apparatus of claim 12 further comprising:
a first slide component comprising recessed molding surfaces positioned at a top edge of an inner surface thereof for forming leashes, hinges and half of the TE band of the closure device.

16 . The molding apparatus of claim 12 further comprising:
the cavity mold component comprising grooves on an inner molding surface for forming knurls on an outer surface of the cap body of the closure device.

17 . The molding apparatus of claim 12 further comprising:
the core mold component comprising copper or a copper alloy.
