FIELD: containers.

SUBSTANCE: multi-section system of containers for storage and delivery, containing at least two containers located one above the other, higher and lower, with length A and width B, while the containers consist of a base of the container and a lid of the container with the possibility of connection by contact elements, contact elements of the bottom of each overlying container are four or eight protrusions in the form of polygonal prisms with a cylindrical face in sector 90° with an outer face having a rounding diameter d₁ directed downwards and grouped into two squares with sides C₁. The contact elements of the lids are made in the form of contact elements of the lid, located at the corners of two squares with side C₂ having interconnected protrusions that are polygonal in cross section rounded inside by cylindrical faces in sector 90° with the same diameter d₂ as the cylindrical faces of the contact elements of the bottom, with d₂=d₁ and C₁=C₂. Moreover, the base of the containers and the bottom of the containers are connected by a sliding fit or by means of a loop. The group of inventions also relates to a method for using a multi-section system of containers for storage and delivery.

EFFECT: improved efficiency of the production stages, the stages of storage, delivery and display on the sales area and ability to demonstrate the maximum number of products of various sizes and volumes in a small sales area.
