US Patent:

RE367176, May 30, 2000

Filed:

Jan 28, 1998

Appl. No.:

9/014518

Inventors:

Roderick Thompson - Solana Beach CA

Assignee:

New Age Products, Inc. - Oceanside CA

International Classification:

B32B 2700
A23P 100

US Classification:

426518

Abstract:

A thin polypropylene sheet is extruded flat, with a thickness in the range of 0. 008 to 0. 060 inches with a Rockwell hardness between 72 and 90 and a flexural modulus between 55,000 psi and 200,000 psi. The resultant surface may be utilized for cutting and chopping foods. A sharp knife will penetrate, but not perforate, the sheet material to not dull the knife while maintaining the integrity of the surface. When flexed around its longitudinal centerline, the sheet material develops substantial cantilever beam strength, so as to transport food articles after preparation into an appropriate container. The questions raised in reexamination request No. 90/004,752, filed Sep. 17, 1997, have been considered and the results thereof are reflected in this reissue patent which constitutes the reexamination certificate required by 35 U. S. C. 307 as provided in 37 CRF 1. 570(e).
