Abstract
Abstract A container for handling, transportation and storage of microscope slides includes a plurality of individual microscope slide-receiving compartments. Each compartment includes a plurality of rounded protuberances extending upwardly in each individual compartment for contacting a lower surface of the microscope slide to space the microscope slide upwardly from an inner surface of the compartments and a plurality of rounded protuberances extending downwardly from one or more cover members to restrain vertical slide movement while maintaining longitudinal and lateral spacing of the microscope slides. The container includes one or more plastic cover members having a generally planar surface overlying the plurality of microscope slides when the cover is in a closed position including a plurality of downwardly extending rounded protuberances within each of the slide-receiving compartments for vertical restraint of each microscope slide with minimum contact against the specimen-receiving face of each slide. The container covers are secured to the container by elongated, flexible hinge material to enable the cover member to be rotated or articulated from the closed position to an open, stackable position disposed adjacent an outer, lower surface of the container. Each cover member includes a plurality of alignment posts received within indentations within a ledge surface of partition walls forming the container compartments to maintain the cover members in a fixed position.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
303 words
A container for removably retaining a plurality of microscope slides in a predetermined spaced relationship, one to another, comprising: a generally planar lower wall having a generally planar inner surface and a generally planar outer surface; a plurality of partition walls extending upwardly from said inner surface of said lower wall defining a plurality of rectangular microscope slide-receiving compartments for spacing a plurality of microscope slides in a predetermined, spaced relationship, longitudinally and laterally one to another, above said inner surface of said lower wall; a plurality of protuberances within each of said slide-receiving compartments extending upwardly from the inner surface of said lower wall a shorter distance than the upward extension of the partition walls, said protuberances adapted to contact a lower surface of a microscope slide to space the microscope slide upwardly from the inner surface of said lower wall while maintaining longitudinal and lateral spacing of said microscope slides; a plastic cover member having a generally planar first surface adapted to overlie a plurality of microscope slides, in spaced relationship therewith, when the cover member is in the closed position, and a generally planar second surface forming an outer surface of the container when said cover member is in a closed position; said first surface including a plurality of rounded protuberances extending thereform within each of the slide-receiving compartments when the cover is in a closed position; and an elongated hinge member formed of a flexible material secured to an outer surface of the container and to said plastic cover member, said hinge member disposed to enable said cover member to be rotated from said closed position wherein the first surface overlies a plurality of microscope slides to an open, stackable position wherein the second surface of the cover member is disposed adjacent the outer surface of the lower wall.
Claim 2
Dependent Claim
303 words
A container for removably retaining a plurality of microscope slides in a predetermined spaced relationship, one to another, comprising: a generally planar lower wall having a generally planar inner surface and a generally planar outer surface; a plurality of partition walls extending upwardly from said inner surface of said lower wall defining a plurality of rectangular microscope slide-receiving compartments for spacing a plurality of microscope slides in a predetermined, spaced relationship, longitudinally and laterally one to another, above said inner surface of said lower wall; a plurality of protuberances within each of said slide-receiving compartments extending upwardly from the inner surface of said lower wall a shorter distance than the upward extension of the partition walls, said protuberances adapted to contact a lower surface of a microscope slide to space the microscope slide upwardly from the inner surface of said lower wall while maintaining longitudinal and lateral spacing of said microscope slides; a plastic cover member having a generally planar first surface adapted to overlie a plurality of microscope slides, in spaced relationship therewith, when the cover member is in the closed position, and a generally planar second surface forming an outer surface of the container when said cover member is in a closed position; said first surface including a plurality of rounded protuberances extending thereform within each of the slide-receiving compartments when the cover is in a closed position; and an elongated hinge member formed of a flexible material secured to an outer surface of the container and to said plastic cover member, said hinge member disposed to enable said cover member to be rotated from said closed position wherein the first surface overlies a plurality of microscope slides to an open, stackable position wherein the second surface of the cover member is disposed adjacent the outer surface of the lower wall.
Claim 3
Dependent Claim
72 words
The container of claim 1 wherein the protuberances extending from the inner surface of the lower wall are rounded and cooperatively disposed with respect to the rounded protuberances extending from the first surface of the cover member to form a pair of tri-axial microscope slide restraints within each microscope slide receiving compartment to restrain each microscope slide from both faces against vertical movement when the cover member is in a closed position.
Claim 4
Dependent Claim
15 words
The container of claim 1 wherein the flexible hinge material is a polymeric mesh material.
Claim 5
Dependent Claim
46 words
The container of claim 1 wherein the flexible hinge material is secured to the container by disposing the hinge material in contact with material within a mold, and thereafter molding the material into a predetermined container shape to embed the hinge material within the container material.
Claim 6
Dependent Claim
51 words
The container of claim 4 wherein the flexible hinge material is secured to the plastic cover by disposing the hinge material in contact with a plastic material within a cover member mold, and thereafter molding the plastic into a predetermined cover shape to embed the hinge material within the cover member.
Claim 7
Dependent Claim
31 words
The container of claim 1 wherein the container includes a continuous peripheral partition wall extending upwardly from, and extending around the entire periphery of, the inner surface of the lower wall.
Claim 8
Dependent Claim
19 words
The container of claim 6 wherein the peripheral wall includes an uppermost surface lying in a generally horizontal plane.
Claim 9
Dependent Claim
72 words
The container of claim 7 wherein the uppermost surface of the peripheral wall includes a plurality of indentations adapted to receive alignment posts extending from the first surface of the cover member, and wherein the first surface of the cover member includes a plurality of alignment posts cooperatively disposed with respect to said indentations such that the alignment posts are received in said indentations with the cover member in a closed position.
Claim 10
Dependent Claim
115 words
The container of claim 8 wherein the second surface of the cover member includes a plurality of indentations in alignment with the alignment posts extending from the first surface of the cover member, and wherein the outer surface of the lower wall includes a plurality of alignment posts extending therefrom cooperatively disposed with respect to the indentations in the second surface of the cover member such that with the cover member in an open, stackable position wherein the second surface of the cover member is disposed adjacent the outer surface of the lower wall, the alignment posts extending from the outer surface of the lower wall are received within the indentations in the cover member.
Claim 11
