A method and apparatus for sealing a container with a cap and a seal member which is adhered to the neck. The seal member is inserted into the cap before the cap is applied to the neck by moving the cap in an axially downward direction relative to the neck to substantially seat the cap on the neck so that the cap cannot be removed without unscrewing the cap. The seal member is firmly held against the neck by the cap while the seal disc is adhered to the neck. In one modification, a pressure application applies a downward directed force to urge the cap against the neck while the seal disc is adhered to the neck. In another modification, the cap is tightened onto the neck at a fine adjustment station to eliminate gaps between the underside of the cap and the neck before the seal disc is adhered to the neck.

[ What is claimed is:] [1.] A method of sealing a container comprising the steps of:positioning a closure on a neck of said container, said closure having a top, a closure skirt depending from said top and a seal disc disposed beneath said top, said neck having an opening, a lip surrounding said opening and a downward extending neck stretch below said lip, said closure skirt and said neck stretch being configured to interengage and retain said closure on said neck when said closure is applied to said neck;moving said closure and said container below a pressure applicator having a profile which is directed downwardly from an inlet end of said pressure applicator to a lowermost level to apply pressure to at least one of said closure and said container to move said closure in a downward direction relative to said neck to bring said closure skirt and said neck stretch into interengagement, said closure being substantially applied to said container as said container and said closure pass below the lowermost level of said pressure applicator;heating said seal disc to at least partially adhere said seal disc to said lip of said neck; andapplying pressure with said pressure applicator to at least one of said closure and said container to hold said seal disc against said lip during said step of heating said seal disc.
