two opposing side faces;
a lid face extending between the two opposing side faces;
a bottom face extending between the two opposing side faces opposite the lid face;
a front face extending between the two opposing side faces and pivotably hinged to the housing;
a rear face extending between the two opposing side faces opposite the front face;
a carrying handle pivotably hinged to the two opposing side faces to rotate relative to the housing, about a swivel axis extending between the two opposing side faces, between a swiveled-out state and a swiveled-in state; and
a lock comprising:
a groove body comprising a groove body surface and a first groove extending into the groove body surface in a groove direction along the swivel axis;
a rib facing the groove body and extending in the groove direction along the swivel axis, wherein the rib and the groove body are rotatable relative to one another about the swivel axis upon rotation of the carrying handle between the swiveled-out state and the swiveled-in state; and
a spring having a spring bias configured to bias the rib and the groove body together along the swivel axis, and move the rib into the first groove when the carrying handle is in at least one of the swiveled-out state and the swiveled-in state;
