ABSTRACT:
A container (10) having a line of weakness (18) at which the container is opened includes an inner closure (20) mounted within the container cover (16) above the line of weakness (18), and an annular sidewall (22) depending below the frangible line of weakness (18). The inner closure (22) protects the line of weakness (18) from the liquid contents, thereby preventing spillage of liquid contents onto outer non-sterile surfaces upon opening of the container. The container prevents the commercially undesireable retention of moisture in the volume (40) defined by the cover (16) and the inner closure (20). The container may be integrity tested using standard testing procedures.
