Beverage container with extendable drinking straw

A beverage container comprising:

• a body having an open top end;
• a removable cap for closing the top end of the body and including a cylindrical side wall having a lateral opening and a top member having a tubular projecting from the underside of the top member to form a nipple;
• a dip tube secured to the nipple and extending into the body;
• an upper straw means linearly movable in the cap and including a tube section and a guide section;
• a dome including a top member and a cylindrical side wall having an elongate slot;
• connector means for mounting the dome on the cap for rotational movement relative to the cap;
• and
• link means for translating the rotational movement of the dome into the linear movement of the upper straw means on the cap, whereby the rotation of the dome causes the upper straw means to linearly move on the cap between a first position wherein the tube section of the upper straw means extends through the lateral opening of the cap and the elongate slot of the dome and is in liquid communication with the nipple of the cap, and a second position wherein the tube section of the upper straw means is withdrawn within the dome and is not in liquid communication with the nipple of the cap.
