Abstract

A glass container (12, 112, 212) includes a side wall (18) circumscribing a central longitudinal axis (A), and includes a neck finish (26, 126, 226), which includes a wall (29, 229) having a radially internal surface (46, 246) and a radially external surface (48, 148, 248) and a rim (30, 130, 230) extending from the wall. The rim has a closing flange (32, 132), a pouring flange (36, 136, 236), and a retaining flange (38, 138) extending between the pouring flange and the radially external surface of the wall. Various dimensions of the rim are disclosed. A packaging (10) includes the glass container and a circular cap plug (14) attached to the rim.

Description

The disclosure refers to glass containers in general and, more particularly, to glass containers that have chamfered neck finishes. BACKGROUND OF THE INVENTION A wide-mouth glass container typically has a neck finish with an outside diameter greater than 38 mm. Some wide-mouth glass containers have chamfered neck finishes that accept foil stoppers, for example, as described in US patent 9,856,059. Other wide-mouth glass containers have neck finishes that flare outwards to accept circular metal caps, for example, as disclosed in US patent 3,561,631. And despite the popularity of circular cap stoppers for use with narrow-neck bottles, these stoppers have not been successfully implemented for wide-mouth glass containers.A round cap includes a metal base wall, a metal skirt for flange fitting onto the container rim, a polymeric O-ring carried by the metal base wall adjacent to the metal skirt, and a metal pull ring extending from one side of the skirt with lateral edges that engage the weakened portions of the skirt and base wall. After the round cap is fitted to the container rim by bottle-capping equipment at a bottling plant, a user can remove the cap by inserting a finger through the pull ring, pulling radially outward and then axially upward to pry the handle from the skirt and base wall along the weakened portions, and then continuing to pull the pull ring until the cap is removed from the container.This type of stopper has not been used successfully in glass containers because it has been difficult to produce a chamfered neck finish for a glass container that meets the pressure and pull-out force specifications of round-top stoppers, but is also consumer-friendly and can be manufactured without significant commercial variations. BRIEF DESCRIPTION OF THE INVENTION According to one embodiment of this disclosure, a glass container includes a base and a side wall extending from the base, circumscribing a central longitudinal axis, and including a neck finish terminating the side wall. The neck finish includes a wall having a radially internal surface and a radially external surface, and a lip extending from the wall and terminating the neck finish.The edge has a sealing flange oriented axially outward and extending substantially perpendicular to the central longitudinal axis, an outer flange oriented radially and axially outward, a retaining flange oriented axially inward and radially outward and extending between the outer flange and the radially external wall surface, a first rounded surface extending between the sealing flange and the outer flange, and a second rounded surface extending between the outer flange and the retaining flange. A fillet surface extends between the retaining flange and the radially external wall surface. The ratio of the radial thickness of the edge at the largest outside diameter of the outer flange of the edge to the radial thickness of the neck finish wall below the edge and between the radially internal and external surfaces is between 1.9:1 and 2.2:1.

DETAILED DESCRIPTION OF THE INVENTION In general, this disclosure applies to a glass container with a neck finish configured solely for use with a circular stopper for favorable manufacturing of the glass container and acceptable pressurization and retention performance of the glass container and stopper. The neck finish configuration may also provide a pleasant feel against the lips of the consumer when drinking a beverage from the container. Referring now specifically to FIGURE 1, a package 10 includes a glass container 12 and a circular lid 14 attached to the container 12. The package 10 can be used for packaging food, beverages, or any other product suitable for use with a glass container. In the illustrated embodiment, the container 12 may include a drink container. In other embodiments, the container 12 may include a pitcher, a bowl, RQRznn / zznz / E / YiAi a cup or any other container suitable to accept the circular lid stopper 14. In any embodiment, the vessel 12 includes a base 16 establishing a base plane P that may be normal or perpendicular to a central longitudinal axis A of the vessel 12. The base 16 need not be entirely flat and may include a butt or trough (not shown). In addition, the vessel 12 includes a side wall 18 extending from the base 16 and circumscribing the axis A.

With reference to FIGURE 1A, the neck 24 may be cylindrical and has a neck finish 26 that terminates the side wall 18 and defines an open mouth 28 of the vessel 12. The neck finish 26 is what is known in the art as a chamfered finish and is not a crown finish or a threaded finish. The neck finish 26 includes a wall 29 that may be cylindrical, and a bead or edge 30 that extends from the wall 29 and projects radially outward from the wall 29 and terminates the neck finish 26.

The skirt 54 includes a cylindrical portion 53 surrounding the outer flange 36 of the container edge 30, and a flanged portion 55 overlapping at least a portion of the retaining flange 38 of the container edge 30. The cylindrical portion 53 may be separated from the outer flange 36, while the flanged portion 55 may be in direct contact with the retaining flange 38.The metal of the stopper 14 may be aluminum, or any other material suitable for joining with glass and being torn.

In the assembly, the seal 56 may extend from the mouth transition flange 34, over the sealing flange 32 and the upper rounded outer surface 42, and down to the outer flange 36. With reference again to FIGURE 2, the rim of vessel 30 is configured for commercially successful use with circular-capped stoppers, such that the configuration facilitates acceptable pressurization and retention performance of the glass vessel 12 together with the circular-capped stoppers, and facilitates the manufacture of the glass vessel 12.
