Abstract
Abstract An integral support post body adapted for mounting in an aperture in a bottom plate of a medical device sterilization case, said body comprising a disk-shaped base whose maximum transverse dimension is greater than the maximum transverse dimension of said aperture, a reduced diameter; cylindrical neck; and a generally frusto-conical tip which comprises an extended frusto-conical side wall extending both upwardly in a direction away from said neck and inwardly and a convex top wall of a transverse peripheral configuration which conforms to and merges with the upper extremity of said side wall, the maximum transverse dimension of said side wall at its lower extremity being greater than the maximum transverse dimension of said aperture and the maximum transverse dimension of said side wall at its upper extremity being less than or equal to the corresponding transverse dimension of said aperture, and the axial length of said body being sufficient that the clearance between the undersurface of the top wall of the case and the upper extremity of the top surface is less than the vertical dimension of a medical device to be supported by said body.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
220 words
In a medical device sterilization case which is adapted to support a medical device during sterilization and which includes an apertured bottom plate, a top wall disposed in spaced relationship above said bottom plate and at least one integral support post body disposed in mounted relation with an aperture of said bottom plate, the improvement comprising 1. said aperture being circular, 2. said support post body comprising a. a disk-shaped base whose maximum transverse dimension is greater than the maximum transverse dimension of said aperture; b. a reduced diameter, cylindrical neck comprising a cylindrical side wall having a diameter approximately equal to the diameter of said aperture and a height approximately equal to the thickness of said bottom plate; and c. a generally frusto-conical tip comprising i. an extended frusto-conical side wall which extends upwardly in a direction away from said neck and inwardly and ii. a convex top wall provided with a transverse peripheral configuration which conforms to and merges with the upper extremity of said side wall, iii. the maximum transverse dimension of said side wall at its lower extremity being greater than the maximum transverse dimension of said aperture and iv. the maximum transverse dimension of said side wall at its upper extremity being less than or equal to the corresponding transverse dimension of said aperture, and
Claim 2
Dependent Claim

Claim 3
Dependent Claim
45 words
the axial length of said body being sufficient that the clearance between the undersurface of the top wall of the case and the upper extremity of the top surface is less than the vertical dimension of a medical device to be supported by said body.
Claim 4
Dependent Claim
