  • Patent number: 5980811
    Abstract: An improved method of molding a container finish for containers containing liquid at or above atmospheric pressures in which the frusto-conical sealing area thereof is formed in substantially unflawed condition. To accomplish this, the mold for the container includes the usual upper and lower members which move axially when the mold is opened, which members mate with a pair of side members which move laterally when the mold is opened. However, as contrasted with prior art molds of this type, the upper mold member is provided with an axially oriented cavity which encloses that portion of the neck finish which includes the sealing surface to a degree wherein the laterally extending parting line at the upper end of the side members is positioned below the lower edge of the frusto-conical sealing surface thus eliminating the presence of either axially oriented or transversely oriented parting lines on the sealing surface itself.

  • Patent number: 5368178
    Abstract: An improved container and closure therefore particularly adapted for use in storing pressurized liquid contents, such as carbonated beverages. As contrasted with conventional crown seals which employ a sealing gasket, the closure effects a sealing action between corresponding frustoconical sealing surfaces on the container finish and an inner surface of the cap, thus eliminating the need for a gasket. The closure includes a tamper indicating means at a lower peripheral edge thereof which is damaged upon engagement with an opening tool or other object.

  • Patent number: 4946055
    Abstract: An improved synthetic resinous molded threaded cap for use on necked containers permitting initial press fit installation and subsequent threaded engagement. The cap is provided with a tear seal, an inner surface of which provides mutual engagement of an inwardly projecting rib with a corresponding rib on the container neck. Rupture of the tear seal removes this rib and allows the cap to be threadedly engaged by further axial displacement of the cap upon the neck. The cap may be molded with a feathered free edge to facilitate removal from a mold without damaging the rib.

  • Patent number: 4933133
    Abstract: A container closure comprises a cylindrical molded utitary member defining a top panel and a skirt depending from the top panel to an open end for securement to the container, the skirt being interiorly tapered at the open end. The taper begins flush with the outer surface of the skirt and ends in a first circumference radially of the central axis of such cylinder. The skirt further defines a bead extending radially interiorly of the skirt to a second circumference radially closer to the cylinder central axis than the first circumference. The closure provides sealing retention pressure in accordance with the radially interior extent of the bead and exhibits evidence of initial removal from the container. The method for making the closure involves the use of a stripper plate to participate in part in defining a mold cavity.

  • Patent number: 4784817
    Abstract: A container closure is comprised of a closure member molded on a liner, the liner having a first surface secured to the closure member and a second surface opposite the first surface and including a member depending therefrom and configured both for effecting sealing of a container and for releasable securement of the liner to a forming member in the course of such molding of the closure member thereon. The closure member and liner materials may thus be diverse, since they are separately formed. While there are separate manufacturing steps for making the liner and the closure member, the customary step of assembling preformed liners with preformed closure members to obtain desired performance diversity therebetween is eliminated.

  • Patent number: 4674642
    Abstract: A container closure includes liner adapted to seal a container having contents under vacuum pressure, and a closure member securing the liner thereto about the liner periphery. An interior extent of the liner is thereby permitted movement relative to the closure member, i.e., is not secured to the closure member. At the point of container initial closure, the liner interior extent is withdrawn under vacuum pressure from its theretofore normal self-biased disposition adjacent the closure member to within the upper neck of the container and is deformed to the extent that initial container pressurization occasions. Upon loss of such initial vacuum pressure, the liner interior extent moves into its normal self-biased disposition adjacent the closure member. Discernment of the disposition of the liner interior extent relative to the closure member is thus indicative of whether the initial vacuum pressure is being maintained or has been lost.
