Abstract
Abstract A package of disposable pipette tips in which tapered pipette tips are supported on trays by projecting through apertures provided in the tray and in which the trays have sidewalls that extend downwardly from the tip supporting surface of the tray a distance greater than the distance the pipette tips project through the supporting surface. The sidewalls of the trays may be configured such that the bottom edge of the sidewall of a tray is supported by a shoulder formed in the sidewall of a tray on which the first tray is stacked. When the trays are thus stacked, the pipette tips on one tray project into the pipette tips on the tray below.

Claim 1
Independent Claim
339 words
A package of pipette tips comprising a first tray having a planar tip supporting surface provided with a plurality of apertures through which pipette tips can project, a first group of tapered pipette tips projecting through the apertures of the tip supporting surface of said first tray, each of said tips having abutment means on the outside periphery of the tip for supporting the tip on the tip supporting surface of said first tray so that the lower part of said tip projects loosely through an aperture thereof, a second tray having a planar tip supporting surface provided with a plurality of apertures through which pipette tips can project, each of said trays being provided with walls depending from the tip supporting surface of the tray a distance at least equal to the length of that portion of a pipette tip projecting through the tip supporting surface of the tray, each of said depending walls being provided with a shoulder below which the wall lies in a substantially vertical plane and above which the wall is inclined inwardly towards the tip supporting surface of the tray, said second tray being supported by the shoulders provided on the walls of said first tray, and a second group of tapered pipette tips projecting through the apertures of the tip supporting surface of said second tray, each of said tips having abutment means on the outside periphery of the tip for supporting the tip on the tip supporting surface of said second tray so that the lower part of said tip projects loosely through an aperture thereof, the position of the abutment means on said second group of pipette tips and the taper and the thickness of the wall of the pipette tips included in said first and said second groups of pipette tips being such that when said second tray of pipette tips is supported on said first tray of pipette tips the pipette tips supported by said second tray nest loosely in the pipette tips supported by said first tray.
