ABSTRACT:
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.
