Abstract
Abstract A video disc package comprises a base member and a cover member hingedly secured to the base member. The members define a cavity for enclosing a centrally-apertured disc record when juxtaposed. A center post includes first and second portions attached respectively to the base and the cover members. Each of the portions has arcuate peripheral surfaces dimensioned for engagement with diametrically opposite portions of the wall defining the central aperture of the record when it is enclosed in the cavity. The first and the second portions are constructed such that they nest within the central aperture during the reception of the record in the cavity.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
166 words
A package comprising: (A) a first member; (B) a second member; said first member and said second member defining a cavity for enclosing a centrally apertured disc record when said members are juxtaposed; and (C) a split center post including: (a) a first portion attached to said first member; said first portion having arcuate peripheral surfaces dimensioned for engagement with diametrically opposite portions of the wall defining said central aperture of said disc record when said disc record is enclosed in said cavity; and (b) a second portion attached to said second member; said second portion also having arcuate peripheral surfaces dimensioned for engagement with diametrically opposite portions of said wall defining said central aperture of said disc record when said disc record is enclosed in said cavity; the construction of said first portion and said second portion being such that said first and second portions interlock and nest within said central aperture of said disc record when said disc record is enclosed within said cavity.
