1. A pre-evacuatable or pre-evacuated container for medical purposes, comprising a container body, a cover and a sealing element for sealingly engaging the container body to the cover when the cover is locked on the container body, wherein:
the container body comprises a bottom, a wall extending upward from said bottom defining a cavity, and an open end, the wall comprising a side wall portion and a projecting portion disposed near the open end of the container body, the projecting portion comprising a first upward-facing flat surface perpendicular to said wall, a second upward-facing surface perpendicular to said wall and forming an inward-facing step, and an outward-facing protrusion having a downward-facing surface, the first upward-facing flat surface comprising a groove within said upward-facing flat surface into which the sealing element is inserted, said groove being dimensioned such that said sealing element is fully disposed within said groove when the cover is locked on the container body, a wall thickness below the inward-facing step greater than a thickness of the side wall; the cover comprises a receiving space for receiving the projecting portion therein, said receiving space having a flat surface for contacting said sealing element and said flat surface facing downward; a gripping element disposed on a perimeter of the cover; the cover and the container body are configured to sealingly engage one another so as to encompass the cavity within said container and to sealingly engage said respective flat surfaces by compressing said sealing element within said groove when the cover is locked on the container body; so that during medical use, said container is capable of sucking in and containing fluids within said cavity when evacuated; said container is capable of maintaining a reduced pressure within said cavity in the absence of an applied vacuum; and the container is evacuatable to a reduced pressure of at least 90,000 Pascals below atmospheric pressure.
