Abstract: The invention relates to an insulating jug (1) having a housing (2) with a handle (4) or like grip formed thereon and a cap (5) and a pouring opening (6) closable by a closure member (9) movable vertically between a closed and an open position by a displacement mechanism (11) with an operating member extending through the cap. The object of the invention is to improve the insulating jug so that it can be opened and closed by a simple operation with one hand, and so that improper handling is avoided. This is achieved in that the closure member (9) is pre-tensioned in the direction (30) of the closed position by the force of a spring (18), and can be held in the open position against the force of the spring (18) by the displacement mechanism (11), in that the operating member (38) of the displacement mechanism (11) is automatically restored to its closed position by the spring (18), and in that the operating member (38) extends to within finger reach of the handle (4).
