  • In the pipette tip container according to the invention, the feeder has protruding corners, which lower edges are below tips placed therein.
  • In the pipette tip container according to the invention, the feeder has elastic links between side walls and elastic holders.
  • In the pipette tip container according to the invention, opposite base side walls have groves for elastic feeder links.
  • In the pipette tip container according to the invention, the tray has rings around holes, on upper edge of which short tips are set.
  • In the pipette tip container according to the invention, the feeder top part has an inner stabilising ring surrounding upper portions of long tips, outside diameter dimension of which is close to the spacing of holes in the tray.
  • In the pipette tip container according to the invention, the base has in its lower part an additional bottom base to house the lower ends of long tips.
  • An advantage of the solution according to the present invention is a fact that the invention enables—by the use of the feeder, to take and carry trays with tips upon the container base, and next to close the container with the feeder which simultaneously is the container cover.

    • DETAILED DESCRIPTION OF THE INVENTION
  • Reference will now be made in detail to the preferred embodiment of the invention, an example of which is illustrated in the accompanying drawings.
  • The container shown in FIG. 1 includes a base (1) and a cover superimposed on it constituting the feeder (2) for trays with pipette tips. The base (1) has, as it is shown in FIG. 2, rigid side walls (3, 4, 5, 6) as well as corner guides (7, 8, 9, 10) protruding above its upper surface, upon which trays with tips are placed. The base (1) has in its upper portion fins (11) with stabilising pins (12). Moreover, two opposite side walls (3, 5) of the base (1) have groves (13, 14). In turn, the feeder (2) has disposed out corners (15, 16, 17, 18), lower edges of which are positioned below tips placed therein. In the base (1) a tray (19) is positioned with plurality of holes (20) for pipette tips (21), as it is shown in FIG. 3
  • FIG. 4 illustrates the feeder (2) which is built from flat and preferably rigid upper portion (22) and four side walls (23, 24, 25, 26), whereas two opposite side walls (23, 25) have elastic holders (27, 28) in their middle portion. Elastic holders (27, 28) are joined with the side walls (23, 25) by the means of elastic links (29, 30), and they have wedge-shaped projections (31, 32) on the feeder (2) inner side.
  • When the feeder (2) is positioned on the tray (19) with tips (21), and the feeder (2) is pressed downwards, the tray (19) with tips (21) nests in the feeder (2) in a stabile manner so that it is supported on wedge-shaped projections (31, 32), while the top portions of the tips (21) abut against the top part (22) of the feeder (2), as it is shown on a view in FIG. 5 and on a section in FIG. 6.
  • Next the tray (19) may be displaced and set—by the use of the same feeder (2)—in another base shown in FIG. 2. To achieve this, the feeder (2) with the tray (19) and pipette tips (21) are set in the base (1) by sliding corners (15, 16, 17, 18) of the feeder (2) on corner guides (7, 8, 9, 10) of the base (1). When the feeder (2) is pressed downwards, edge-shaped projections (31, 32), which abut against side walls (3, 5), decline sideways together with the elastic holders (27, 28) and release the tray (19) with tips (21). The tray (19) is stable set in the base (1) by the use of stabilising pins (12) in the base (1) and corresponding stabilising holes in the tray (19), as it is shown in relation to FIG. 3. This way the tray (19) with tips (21) is prepared for analytical tests, whereas it is then possible to place the feeder (2) on the base (1) and to close the container with tips (21).
  • In case of using short tips (33), which flange length is shorter than the distance between the tray (19) and the upper portion (22) of the feeder (2) as compared to tips (21) shown in FIG. 6, in order to stabilise their position in the feeder (2) by abutting against upper portion (22) of the feeder (2), the tray (19) has rings (34) around holes, on which upper edges short tips (33) are set, as it is shown on a view in FIG. 7 and on a section in FIG. 8.
  • In turn, for long tips (35), which flange outside diameter dimension is close to the spacing of holes in the tray (19), for the sake of stabilising their position in the feeder (2), the upper portion (22) of the feeder (2) has internal, preferably rectangular stabilising ring (36) which surrounds all upper portions of long tips (35). Moreover, the height of a side wall of the feeder (2) is adjusted to the flange length of long tips (35), while the base (1) has in its lower portion an additional bottom base (37) to house lower parts of long tips (35), as it is shown on a view in FIG. 9 and on a section in FIG. 10.
  • Pipette tips (21) are supplied in a bulk container which contains, as it is shown in FIG. 11, a stack of trays (19) with holes (20) placed one upon another, wherein tips (21) are set. From this stack by the use of the feeder (2) subsequent trays (19) with tips (21) are taken, beginning with the topmost tray (19), and they are carried onto the base (1).
