Closure device for a container

A closure device for a container neck, the closure device having a cap which is actuatable between a closed configuration and an open configuration relative to the container neck, the cap comprising:

• a base;
• an outer wall extending circumferentially around the base;
• a plug seal extending from the base, at an inner face of the cap, and spaced from the outer wall to define a channel for receiving the container neck and for forming a seal against an inner wall of the container neck when the cap is in the closed configuration;
• a lifting member extending from the base and positioned radially inwardly from the plug seal, the lifting member having a contact face at a free end of the lifting member for contacting a top end of the container neck during actuation of the cap from the open configuration to the closed configuration, wherein the lifting member is partially connected to the plug seal.

A closure device for a container neck, the closure device having a cap which is pivotable between a closed configuration and an open configuration relative to the container neck, the cap comprising:

• a base;
• outer wall extending circumferentially around the base;
• a plug seal extending from the base, at an inner face of the cap, and spaced from the outer wall to define a channel for receiving the container neck and for forming a seal against an inner side wall of the container neck when the cap is in the closed configuration;
• a lifting member extending from the base and positioned radially inwardly from the plug seal, the lifting member being positioned at a pivot-side of the cap and having a contact face at a free end of the lifting member for contacting the container neck during actuation of the cap from the open configuration to the closed configuration;
• and
• a protruding member extending from the base and positioned radially inwardly from the plug seal, the protruding member being positioned on a side of the cap which is opposite to the pivot-side.
