Abstract

A thermoformed blister package for a surgical instrument. The package has a tray having at least one cavity having at least one undercut and an instrument can be quickly released from a cavity and from the package without touching the instrument. The package also has an interlocking projection for efficiently storing packages in a dispenser container.

Claims

1. A thermoformed blister package, comprising:

a tray having a top, a bottom and a center;

a flange extending outwardly from the tray;

a plurality of cavities in said tray for receiving a surgical instrument wherein each said cavity has a top opening and wherein at least one of the cavities has at least one undercut extending from the tray adjacent to the top of the at least one cavity for retaining at least a portion of a said instrument within the cavity, each undercut partially extending into the top opening of the cavity thereby forming a gap; and

,

means for quickly releasing a said instrument from the tray without touching the instrument wherein the means for quickly releasing the instrument from the tray comprises two finger pads extending from the bottom of the tray and spaced sufficiently apart to open up the gap sufficient to release the instrument when the pads are pressed while holding the outwardly extending flange.

2. The package of claim 1 wherein at least one cavity having the at least one undercut has a substantially circular cross-section.

3. The package of claim 1 wherein the bottom of the tray beneath one cavity in said tray extends downwardly to form an interlocking projection thereby dividing the bottom of the tray into an interlocking projection and an interlocking bottom section, wherein said projection is offset from the center of the tray such that the interlocking projection and interlocking bottom section of one package can interlock with the interlocking projection and interlocking bottom section of another package.
