ABSTRACT:
A cap liner for sealing an opening between a bottle and a cap secured to the bottle. The cap liner includes a substantially fluid impervious film and a resilient, compressible foraminous reinforcing web bonded to one side of the film. The cap liner is mounted on the cap so that the opposite side of the film is adjacent to the bottle when the cap is secured to the bottle. The foraminous web is compressed between the bottle and the cap so as to resiliently urge the film into sealing contact with the bottle circumferentially about the opening.
