Abstract

Abstract A tray-like holder for flat rectangular objects, such as microscope slides, into which such objects can be easily placed and from which such objects can be easily withdrawn comprises a base with upstanding elongated sidewalls and transverse endwalls to form a major elongated receptacle. This major receptacle is divided into individual smaller receptacles by a plurality of vertical partitions which extend transversely inwardly from each of the longitudinal sidewalls. Between adjacent partitions there is located an abutment on or adjacent to the corresponding longitudinal sidewall. A row of openings in the base is located adjacent and generally parallel with at least one of the longitudinal sidewalls, each of the openings being located between adjacent transverse partitions. An object can be easily placed on the base between adjacent partitions with one end of the object engaging an abutment and the other end of the object extending partially over a corresponding opening in the base. The object can be easily removed by placing a finger into the base opening against the exposed end of the object and lifting the object.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 225 words
A tray-like holder for accommodating a plurality of like elongated flat rectangular objects, such as microscope slides, in side-by-side spaced relation and from which such objects can be easily withdrawn, comprising a tray-like member having a base portion and opposing first and second longitudinal side walls, spaced first abutment means on said base extending transversely inwardly from said first longitudinal side wall, located for engagement by side edge portions of flat rectangular objects placed on said base and operabLe to position such objects in spaced relation, and second abutment means on said member projecting longitudinally from said first abutment means located for engagement by end edge portions of said flat rectangular objects when the latter are so positioned by said first abutment means, said base having circular cut-away portions formed by hemispherical depressions in said base located between adjacent first abutment means for positioning adjacent thereto of end edge portions of said flat rectangular objects when the latter engage said first and second abutment means, the wall surfaces of said first longitudinal side wall between adjacent spaced first abutment means being curved to correspond to the vertical projected edge of the adjacent cut-away portions in said base, said second abutment means being formed as a ridge joining said cut-away portions facilitating digital access to the end edge portions of said flat rectangular objects adjacent thereto.
Claim 2
Dependent Claim 225 words
A tray-like holder for accommodating a plurality of like elongated flat rectangular objects, such as microscope slides, in side-by-side spaced relation and from which such objects can be easily withdrawn, comprising a tray-like member having a base portion and opposing first and second longitudinal side walls, spaced first abutment means on said base extending transversely inwardly from said first longitudinal side wall, located for engagement by side edge portions of flat rectangular objects placed on said base and operabLe to position such objects in spaced relation, and second abutment means on said member projecting longitudinally from said first abutment means located for engagement by end edge portions of said flat rectangular objects when the latter are so positioned by said first abutment means, said base having circular cut-away portions formed by hemispherical depressions in said base located between adjacent first abutment means for positioning adjacent thereto of end edge portions of said flat rectangular objects when the latter engage said first and second abutment means, the wall surfaces of said first longitudinal side wall between adjacent spaced first abutment means being curved to correspond to the vertical projected edge of the adjacent cut-away portions in said base, said second abutment means being formed as a ridge joining said cut-away portions facilitating digital access to the end edge portions of said flat rectangular objects adjacent thereto.
Claim 3
Dependent Claim 111 words
A holder according to claim 1 having spaced third abutment means extending transversely inwardly from said second longitudinal sidewall in opposing alignment with said first abutment means, said third abutment means located for engagement by side edge portions of flat rectangular objects placed on said base and being cooperable with said first abutment means to position such objects in spaced relation, said second longitudinal sidewall having substantially flat wall surface portions between adjacent spaced third abutment means which form fourth abutment means for engagement with end edge portions of said flat rectangular objects opposite those engaged by said second abutment means when said objects are in operative position on said holder.
Claim 4
Dependent Claim 35 words
A holder according to claim 2 wherein the base is divided into two equal segments by a transverse wall member formed by extension and joinder of an opposing pair of first and third abutment means.
Claim 5
Dependent Claim 19 words
A holder according to claim 2 also having cut-away portions in the base located between adjacent third abutment means.
Claim 6
Dependent Claim 40 words
A holder according to claim 4 wherein the cut-away portions located between adjacent third abutment means are generally rectangular with rounded corners and are formed by depressions in the base generally in the form of vertical projections of such shape.
