Abstract: A drinking tube (1) consisting of two channels (2, 3) which when connected to one another and which form a closed cross section in which the edge regions (4) overlap, lie one on top of the other in a sealing manner or interlock with each other. The channels (2, 3) are each formed symmetrically with respect to a common axis of symmetry (5), wherein a) the height (h) of the channels (2, 3) in relation to the axis of symmetry (5) is smaller than the width (b) and/or b) the cross section of the inner channel (3) is equal to or slightly larger than the cross section of the outer channel (2), so that a tension exists between the channels (2, 3) lying one inside the other.

Abstract: A flat electronic storage medium, in particular a USB memory stick which has a fastening facility. The fastening means (1) is integrated into the housing (2) of the storage medium in that the housing (2) has a slit through-opening (3) or a lateral hook-shaped housing extension (11) of a flat side of the housing, the hook end (12) of which extension forms a slit (4) with the housing (2), and each slit of the slit through-opening (3) or slit (4) can be closed off by a pin (5) arranged in a guide (6) such that said pin can slide in the housing (2).

Abstract: A grill device which has a frame in which heating means are arranged below a grate. The heating means have a grease-deflecting cover supported on the frame and has oblique guide plates for dripping grease below the heating means, via which the dripping grease can be directed towards a collecting channel. The grate (2) is arranged on a support (1.1) on the upper edge region of the frame (1) and is divided into grate sections. The grease-deflecting cover (3) is made of flat fins (3.1-3.m) that are arranged in sequence like blinds and are adjustably arranged above the heating means (4). The guide plates (5) are divided into overlapping guide plate sections (5.1, 5.2) which can be removed from the frame (1).
