A composite closure type container assembly that is designed for use with unthreaded containers includes a container having an unthreaded outer surface and an opening that is defined by an upper rim, a sealing disc that is sized and shaped to cover the opening and to seal against the upper rim and a securement member that is removably anchored to the container for securing the sealing disc on the container. In one embodiment, the securement member is removably anchored to the container by using a tight frictional engagement. In a second embodiment, the anchoring is accomplished by shaping the container so as to have a downwardly depending skirt that engages and retains the securement member in position until the container assembly is opened.

What is claimed is: 1. A composite closure for sealing a container having an outer surface and an opening that is defined by an upper rim, comprising: a sealing disc that is sized and shaped to cover the opening, said sealing disc having a sealing surface on a lower side thereof that is constructed and arranged to contact and form a seal with the upper rim of the container, said sealing disc and said container being engaged so that only said sealing surface engages the container; and securement means for securing said sealing disc on the container, said securement means being heat-shrunk onto the container being securely anchored to the container through frictional engagement, said securement means further comprising a removable upper portion that is frangibly connected to the remainder of said securement means, said removable upper portion comprising disc engaging structure for engaging and lifting the sealing disc away from the upper rim of the container when said removable upper portion of said securement member is removed; said securement means further comprising cam means, interposed between said removable upper portion and the remainder of said securement means, for exerting an upward force on said removable upper portion when said removable upper portion is being removed during opening of the closure. 2. A composite closure according to claim 1, wherein said cam means is constructed and arranged to be operative when said removable upper portion is twisted relative to the remainder of said securement means. 3. A container assembly, comprising: a container comprising an outer surface and an opening that is defined by an upper rim, said outer surface having no threading for engaging a closure; a sealing disc that is sized and shaped to cover the opening, said sealing disc having a sealing surface on a lower side thereof that is constructed and arranged to contact and form a seal with the upper rim of the container, said sealing disc and said container being engaged so that only said sealing surface engages the container; and securement means, removably anchored to said container, for securing said sealing disc on the container, said securement means comprising a securement member that engages an upper side of said sealing disc to prevent the sealing disc from disengaging from the upper rim of said container, and wherein said securement member further comprises a tamper evident band that is constructed and arranged to engage said container so as to prevent upward movement of said tamper evident band, whereby said tamper evident band anchors said securement member to said container in order to prevent the sealing disc from disengaging with the upper rim of said container; said securement member further comprising cam means, interposed between said tamper evident band and said removable upper portion for exerting an upward force on said removable upper portion when said removable upper portion is being removed during opening of the closure. 4. A container assembly according to claim 3, wherein said tamper evident band is constructed and arranged to frictionally engage the outer surface of the container in order to secure the tamper evident band to the container. 5. A container assembly according to claim 3, wherein said securement member further comprises a removable upper portion that is frangibly connected to said tamper evident band, said removable upper portion comprising disc engaging structure for engaging and lifting the sealing disc away from the upper rim of the container when said removable upper portion of said securement member is removed. 6. A container assembly according to claim 3, wherein said cam means comprises at least one projection on one of said tamper evident band and said removable upper portion and a ramp for engaging said projection on the other of said tamper evident band and said removable upper portion. 7. A container assembly according to claim 3, wherein said cam means is constructed and arranged to be operative when said removable upper portion is twisted relative to said tamper evident band. 8. A container assembly according to claim 7, wherein said removable upper portion comprises gripping means on an outer surface thereof for facilitating secure gripping of said removable upper portion during removable of the closure by a consumer. 9. A container assembly, comprising; a container comprising an outer surface and an opening that is defined by an upper rim, said outer surface having no threading for engaging a closure; a sealing disc that is sized and shaped to cover the opening, said sealing disc having a sealing surface on a lower side thereof that is constructed and arranged to contact and form a seal with the upper rim of the container, said sealing disc and said container being engaged so that only said sealing surface engages the container; and securement means, removably anchored to said container, for securing said sealing disc on the container, said securement means being heat-shrunk onto the container so that it is securely anchored to the container through frictional engagement, and wherein said securement means comprises a removable upper portion that is frangibly connected to the remainder of said securement means, said removable upper portion comprising disc engaging structure for engaging and lifting the sealing disc away from the upper rim of the container when said removable upper portion of said securement member is removed; said securement means further comprising cam means, interposed between said removable upper portion and the remainder of said securement means, for exerting an upward force on said removable upper portion when said removable upper portion is being removed during opening of the closure. 10. A container assembly according to claim 9, wherein said cam means is constructed and arranged to be operative when said removable upper portion is twisted relative to the remainder of said securement means.
