a one-sided figure consisting of a tapered tube the narrow end of which is bent back, run through the side of the tube, and flared to join the wide end, thereby allowing any two points on the figure to be joined by an unbroken line.
(maths) a surface formed by inserting the smaller end of an open tapered tube through the surface of the tube and making this end contiguous with the other end
A smooth surface that has no inside or outside. It is often pictured in ordinary space as a tube that bends back upon itself, entering through the side and joining with the open end.

The Klein bottle is named after the German mathematician Felix Klein (1849-1925). Compare Möbius strip.
