Abstract: The valve described, which is suitable for use in bag-in-box packaging, consists of a housing (1), an obturator (2) and actuating means (3). The obturator (2) has a bottom plate (20) which seals off the valve outlet (11). The obturator (2) consists essentially of a piston (22) with an internal thread (27). The internal thread in the piston (22) engages with the external thread (31) of a pin (30) forming part of the actuating means (3) which is designed as a twist grip. Suitable positively locking means (16, 17, 34, 37) enable the actuating means (3) to be snapped directly on to the valve housing (1).

Abstract: A snap-on, plastic hinged closure in a single piece has a bottom part and a lid interconnected by an integral hinge in the area of the superimposed outer walls of the bottom part and lid, as well as at least one intermediate element that ensures the snap-on effect. The hinge consists of at least two non-intersecting swivelling axes (6). A pressure-resistant tilting element (7) is arranged between two adjacent swivelling axes (6), so that during opening or closing, first the bottom part (1) and the tilting element (7), then the tilting element (7) and the lid (2) partially swivel around the swivelling axis (6).

Abstract: A lower wall (22) is arranged at a distance beneath an upper wall (21). The lower wall (22) is convex from a central region (23) and then at least approximately espouses the shape of the upper wall (21). An overlap region (27) is thus formed. On the opposite side the lower wall (22) is bent upwards parallel to and flush with the longitudinal edge (26) towards the upper wall (21) and follows the latter back to the centre of the plate. A second overlap region (28) is thus formed. This design avoids the formation of a hollow space in the bonding region of the neighbouring metal plate. In addition, it permits the insertion of metal strips running parallel to the longitudinal edges of both walls. It is also possible to fit a spacer extending over the entire central region (23) in the space between the upper (21) and lower (22) walls to reinforce the entire structure.

Abstract translation: 下壁（21）布置在下壁（21）下方的距离处。 下壁（22）从中心区域（23）凸出，然后至少近似地支撑上壁（21）的形状。 由此形成重叠区域（27）。 在相对侧，下壁（22）向上平行向上弯曲并朝向上壁（21）与纵向边缘（26）齐平，然后将后壁回到板的中心。 因此形成第二重叠区域（28）。 该设计避免了在相邻金属板的接合区域中形成中空空间。 此外，它允许插入平行于两个壁的纵向边缘延伸的金属带。 也可以在上部（21）和下部（22）壁之间的空间中安装一个在整个中心区域（23）上延伸的间隔物，以加强整个结构。
