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 membe

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).

An insulating jug having a housing with a handle or like grip formed thereon; a connecting piece in the upper part of the housing; a hollow cap insertable into said connecting piece; a pourer formed on the housing; a pouring opening on said housing; a displaceable closure member having a guide stem, said closure member being arranged on the underside of the bottom of the cap; and a displacement mechanism with an operating member extending through the cap for vertically displacing said closure member between a closed and an open position; characterized in that a spring exerts a force on the closure member to pretension said closure member in the direction of the closed position; said displacement mechanism being actuatable to retain said closure member in the open position against the force of the spring, said operating member being automatically restorable to its closed position by the force of the spring, said operating member extending to within finger reach of the handle, the displacement mechanism and the spring being arranged in the hollow cap; a ring seal for sealing the guide stem in or on the inner side of the bottom of the cap; a stop for limiting the opening movement of the closure member, said stop comprising an annular extension projecting from the guide surface of a guide cylinder in the side of the cap; and a ring seal being arranged between the stop and a shoulder on the guide stem, said ring seal concurrently cooperating with a cylindrical surface of the guide stem and the guide surface of the guide surface in the side of the cap.
