Containers, each of which may be used as such and as a lid when they cooperate to form a closed container, and which can be stacked and thus is secured against mutual displacement to intrude laterally

摘要

Vessels, in particular plates and pots, can be used respectively as receptacles (1) and covers (2), can be stacked, together with the closed vessels thus formed, and are prevented from lateral mutual displacement owing to the fact that their contact surfaces are provided with mutually-engaging alternating ridges or lugs and grooves or slots (3, 4).
