Abstract: A holding device configured to support medical containers includes a supporting plate having a first surface, a second surface, a peripheral edge between the first surface and the second surface, and a plurality of openings through the supporting plate configured to receive the medical containers. The surfaces of the supporting plate include a peripheral lower portion extending inward from the peripheral edge; at least one upper portion enclosed by the peripheral lower portion; and at least one upwardly angled portion extending between the lower portion and the upper portion. The holding device further includes a plurality of chimneys protruding from the first surface and/or the second surface of the supporting plate at least partially enclosing the plurality of openings, such that the plurality of chimneys guide insertion of the medical containers into the plurality of openings.

Abstract: A holding device configured to support medical containers includes a supporting plate having an upper surface, a lower surface, and a plurality of openings through the supporting plate configured to receive the medical containers. The holding device also includes a plurality of chimneys protruding from the upper surface and/or the lower surface of the supporting plate enclosing the openings, such that the plurality of chimneys guide insertion of the medical containers into the plurality of openings: and a plurality of reinforcing ribs protruding from the supporting plate extending between the plurality of chimneys. The plurality of reinforcing ribs include a first end portion extending radially from a first chimney of the plurality of chimneys and a second end portion extending radially from an adjacent second chimney of the plurality of chimneys.
