Abstract
Abstract A package for transporting a glass slide which carries a specimen for laboratory analysis makes use of a particularly light-weight yieldable material of the nature of Styrofoam. A thin base sheet of the material is provided with a rectangular recess slightly smaller than the glass slide and into which the slide may be pressed. Three edges of the base are each provided with a ridge leaving a fourth edge clear and a thin cover sheet of the same Styrofoam material fits snugly within the ridges where it is yieldably held in position covering the glass slide.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
157 words
A holder for a specimen slide of substantially rectangular shape, said holder comprising a base sheet of lightweight yieldable moldable material of the same general configuration as said slide, a recess in the upper face of the base sheet of substantially the same configuration as said slide and spaced inwardly of peripheral edges of the base sheet forming a frame around said recess, said recess having a size no greater than the size of the slide and providing thereby retention means for holding the slide in the recess, a cover sheet of light-weight formable material and of substantially the same configuration as said base sheet, a retention ridge at the edge of said base sheet and extending for a distance around the perimeter defining a receptive area, said cover sheet having a size no smaller than said receptive area whereby the cover sheet is adapted to be held by the ridge in closed position over the recess.
Claim 2
Dependent Claim
157 words
A holder for a specimen slide of substantially rectangular shape, said holder comprising a base sheet of lightweight yieldable moldable material of the same general configuration as said slide, a recess in the upper face of the base sheet of substantially the same configuration as said slide and spaced inwardly of peripheral edges of the base sheet forming a frame around said recess, said recess having a size no greater than the size of the slide and providing thereby retention means for holding the slide in the recess, a cover sheet of light-weight formable material and of substantially the same configuration as said base sheet, a retention ridge at the edge of said base sheet and extending for a distance around the perimeter defining a receptive area, said cover sheet having a size no smaller than said receptive area whereby the cover sheet is adapted to be held by the ridge in closed position over the recess.
Claim 3
Dependent Claim
