Abstract

The present invention relates to systems and methods involving interconnected plate components, including bases, lids and covers, interconnected in a manner such that a continuous strip of each component is prepared. The continuous strips may be stored as rollstock in a reel style. The physical properties of each continuous strip allow the base, lid and/or cover to include means for positive control. In one embodiment, the continuous strip of bases is advanced and processed through an automated system with positive control, and remains in the form of a continuous strip until agar in the bases is cured, at which time the bases are singulated. When a lid is applied to a base using methods described herein, an airtight seal is formed improving the quality of culture media used in testing.

First claim

The invention claimed is:

1. A system of dispensable plates for preparing and inoculating media comprising:
a first continuous strip of bases each having a reservoir portion and a lip surrounding the reservoir;
a second continuous strip of lids, each lid adapted to be placed on and attached to the lip of the base; and
a third continuous strip of covers having a peripheral planar surface extending between an at least one edge of the cover and a raised portion remote from the at least one edge of the cover, the raised portion rising from the peripheral planar surface such that the raised portion includes a wall extending upward from the peripheral planar surface, each cover adapted to be placed over the lip of the base and attached directly to the base.

2. The system of claim 1 , wherein the base, the lid and the cover are made from a thermoplastic material.

3. The system of claim 1 , wherein the base, the lid and the cover are adapted to advance through an automated injection and inoculation system subject to positive control.

4. The system of claim 3 , wherein the base, the lid and the cover include a plurality of timing holes.

5. The system of claim 1 , wherein the wall of the raised portion includes an at least one opening for ventilation.

6. The system of claim 4 , wherein the lid and the base each include four edges and two edges of the lid are longer than two corresponding edges of the base.
