Sip lid for a container

A container having a closed top and a lid, thereover, the lid having a sip opening with a recloseable sip cover, the lid further having a mechanism for:

• moving the sip cover away from the sip opening, and
• opening the closed top of the container, thereby simultaneously providing access to container contents through the sip opening.

A lid for a container having a membrane cover, the lid comprising:

• a top and a bottom, a stationary main body and a rotatable center portion, the center portion having a projection extending downwardly from the bottom,
• the center portion being rotatable relative to the main body to cause the projection to move downwardly towards the membrane cover.

A lid for a container having a membrane covering its open top, the lid comprising:

• a main body;
• and
• a rotatable member, rotatable relative to the main body, the rotatable member comprising an arm radially spaced from a main part of the rotatable member and having a projection, the projection being movable in a direction to pierce a membrane of a container on which the lid is mounted when the rotatable member is rotated.

A container lid having a main body surrounding a rotatable center portion, the main body having a sip opening and the center portion having a sip cover which selectively covers and uncovers the sip opening, the center portion also having a projection which, upon rotation of the center portion relative to the main body, moves downwardly in a position whereat the projection would pierce the membrane of a container when the lid is located on a container,

• and wherein movement of the center portion relative to the main body essentially simultaneously uncovers the sip opening and pierces the membrane.
