A gasket for sealing a channel of a mounting cup to a bead of a container, comprising gasket material having a first and second portion, the first portion for being positioned at least partially within the channel portion of a mounting cup and the second portion having an inner surface and an outer surface, the inner surface for being positioned contiguous to a smooth skirt of the mounting cup, and at least one self supporting protrusion associated with the second portion of the gasket material, the protrusion extending radially outward from the second portion.
A gasketed mounting cup comprising a panel, a smooth skirt integral with and depending from a periphery of the panel, the skirt being outwardly flared to form an annular channel for receiving a container bead that defines a container opening, and a gasket comprising a first and second portion, the first portion being at least partially within the channel of the mounting cup and the second portion being in contact with the skirt of the mounting cup, the gasket further comprising at least one self supporting protrusion associated with the second portion of the gasket, the protrusion extending radially outward from the second portion such that the protrusion can engage the container bead, maintaining the gasket on the container bead during a filling operation.
A gasketed mounting cup comprising a panel, a smooth skirt integral with and depending from a periphery of the panel, the skirt being outwardly flared to form an annular channel for receiving a container bead that defines a container opening, and a gasket comprising a first and second portion, the first portion being at least partially within the channel of the mounting cup and the second portion being in contact with the skirt of the mounting cup, the second portion of the gasket comprising a self supporting, folded over section of the gasket extending outwardly and away from the skirt, for engaging the container bead and maintaining the mounting cup in position on the container bead prior to clinching of the mounting cup to the container bead.
