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; andthe container is evacuatable to a reduced pressure of at least 90,000 Pascals below atmospheric pressure. 2. The container according to claim 1, wherein the sealing element is in the form of an O-ring seal. 3. The container according to claim 1, wherein the projecting portion is adjacent the open end of the container and has a greater wall thickness than the wall thickness of other portions of said wall. 4. The container according to claim 1, wherein the sealing element is releasably connected to the container body. 5. The container according to claim 4, further comprising a clamping or snap connection for maintaining an engagement of the cover to the container body. 6. The container according to claim 1, wherein the cover and the container body are fixedly connectable or connected together. 7. The container according to claim 1, wherein at least one of the container body and the cover comprise a plastic material. 8. The container of claim 7, wherein the plastic material comprises one of polyvinyl chloride (PVC), polypropylene (PP), or polyethylene terephthalate (PETP). 9. The container according to claim 1, wherein the container body additionally comprises at least one reinforcing rib. 10. The container according to claim 9, further comprising respectively mutually oppositely disposed said reinforcing ribs. 11. The container of claim 10, further comprising four of said reinforcing ribs. 12. The container according to claim 9, wherein the at least one said reinforcing rib extends along the container wall. 13. The container according to claim 9, wherein the at least one said reinforcing rib extends along said wall and said bottom. 14. The container according to claim 1, further comprising a scale. 15. The container according to claim 1, wherein the cover comprises at least one connection portion for the connection of a hose. 16. The container according to claim 1, wherein the cover comprises at least one suspension device for suspending the container from a holding device. 17. The container according to claim 16, wherein the holding device comprises an infusion stand. 18. The container according to claim 1, wherein the cover further comprises a rim portion which adjoins the downward-facing flat surface and which is angled substantially at a right angle relative thereto, and an inward flange which is so arranged at a spacing relative to the rim portion such that the receiving space is between the rim portion and the flange. 19. The container according to claim 18, wherein said flange sealingly engages said downward-facing surface of the projecting portion of the container body. 20. The container according to claim 1, wherein the wall portion narrows in a direction distal-to-proximal to the bottom. 21. The container according to claim 1, wherein the downward facing surface of said protrusion has a dimension for engaging an upward-facing rim portion of said cover and locking said cover to said container by a snap-fit. 22. 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;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; andthe container is evacuatable to a reduced pressure of at least 90,000 Pascals below atmospheric pressure wherein the cover and the container body are welded together.
