Abstract
Abstract A tissue specimen container for pathological use consists of a hollow cylindrical body member which comprises a permanent magnet and ferro-magnetic end closures which are magnetically held against the end faces of the body member to complete the container. At least one of the end closures includes a screen portion for admitting treating fluid to the interior of the container.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
70 words
A tissue specimen container comprising a tubular body member means and closure means adapted to extend across the opposite ends of said body member means in axial abutment therewith to form a tissue specimen receiving chamber, at least one of said means comprising permanent magnet means and the other of said means being magnetically attractable thereto whereby the container is releasably held in closed assembly by axially directed magnetic force.
Claim 2
Dependent Claim
70 words
A tissue specimen container comprising a tubular body member means and closure means adapted to extend across the opposite ends of said body member means in axial abutment therewith to form a tissue specimen receiving chamber, at least one of said means comprising permanent magnet means and the other of said means being magnetically attractable thereto whereby the container is releasably held in closed assembly by axially directed magnetic force.
