A body has a threaded inner surface removably engageable with an open end
portion of a beverage bottle. A lid is directly conjoined to the body and
is offset below a top surface of the body for minimizing accidental
contact therewith during non-use conditions. A mechanism for detaching
the lid from the body is included in such a manner that a first perimeter
portion of the lid becomes disengaged from an inner perimeter of the
aperture while a second perimeter portion of the lid remains directly
affixed to the inner perimeter of the aperture and thereby defines a
linear fulcrum axis about which the lid can be repeatedly articulated
during operating conditions. The lid is selectively articulated
thereafter by placing a user's lips against the detaching mechanism so
that the user may quickly and readily pivot the detaching mechanism
without using the user's hands.
