Abstract: The invention relates to a bottle case (10, 10?), including a case base (11), four side elements (12, 13, 14, 15) extending from the base, and a framework (16) having compartments (17) for accommodating bottles, wherein the bottle case (10, 10?) also has a mechanism (20) on at least two opposite side elements and on the case base for rotated stacking of a plurality of bottle cases. The bottle case (10, 10?) is suitable for transporting bottles whether the bottles are full or empty and for transporting the cases back and forth in an empty state.

Abstract: The ignition cable of a motor vehicle engine is permanently connected at each end to the shell component of a connector. Each shell is of the same design and has sawtooth catch ridges. A mating plug connector, for example a apart of an interposed connector housing an interference suppression resistor and fitting onto an electrical component such as a spark plug, distributor cap, spark coil or the like, likewise, has sawtooth catch ridges so that the force for joining the shell and plug is substantially less than necessary for pulling them apart. The steeper sides of the catch ridges on the plug, however, are less steep when the plug is a connection stud of an electrical component of the ignition system, such as the distributor cap, spark coil or the like, so that when the ignition cable is pulled, the cable or interposed connector will come off the distributor cap or spark plug without separating the cable from any detachable "interposition" connector that may be connected to the cable.
