Abstract
Abstract For vial samples of milk collected along a route of dairy farms, a sample vials tray is provided of foldable mode that can be readily accommodated within the limited-volume ice chest of the route agent's truck. At the agent's milk processing plant, the same tray, and with the sample vials undisturbed therein, can be employed in the non-folded and latched condition required for automated laboratory analysis of milk samples contained in the tray-housed vials. A multi-prongs type holder holds each vial in a secure condition during the vehicular journey from dairy farm to milk processing plant. The foldable tray utilizes a special hinge that is relegated to a non-obtrusive location that does not interfere with the tray's usage in concert with automated laboratory analytical equipment.

Claim 1
Independent Claim
296 words
Sample vials tray having a finite-length extending between a lead-end and a trail-end, said tray having a midpoint located substantially midway said lead-end and trail-end and comprising: (A) a first-channel extending lengthwise from said trail-end to said midpoint and comprising: (Ai) a horizontal roof-panel having means defining a plurality of apertures spaced therealong to accommodate an upper portion of each of a plurality of sample vials, (Aii) a horizontal floor-panel, and (Aiii) an upright side-panel connection between said first-channel roof-panel and said floor-panel, said side-panel having a pair of upright planar opposed surfaces including an inner-surface and an outer-surface; (B) a second-channel extending lengthwise from said lead-end to said midpoint and comprising: (Bi) a horizontal roof-panel having means defining a plurality of apertures spaced therealong to accommodate an upper portion of each of a plurality of sample vials, (Bii) a horizontal floor-panel, and (Biii) an upright side-panel connection between said second-channel roof-panel and said floor-panel, said side-panel having a pair of upright planar opposed surfaces including an inner-surface and an outer-surface; (C) at said tray midpoint, hinge means pivotably connecting said first-channel to said second-channel, said hinge means being located at the side-panels of both channels but being relegated inwardly from outer-surfaces of said side-panels whereby said tray can be alternatively employed: (Ci) a stored vials, folded mode wherein the outer-surface of the first-channel side-panel lies alongside the outer-surface of the second-channel side-panel, and (Cii) a vials laboratory analysis mode wherein the side-panels of the two channels extend colinearly in opposite directions from the tray midpoint; and (D) located wholly remote from said hinge means, latch means attached to one channel to releasably latch the other channel into colinearity with the one channel and thereby releasably maintain the laboratory analysis mode for said sample vials tray.
Claim 2
Dependent Claim

Sample vials tray having a finite-length extending between a lead-end and a trail-end, said tray having a midpoint located substantially midway said lead-end and trail-end and comprising: (A) a first-channel extending lengthwise from said trail-end to said midpoint and comprising: (Ai) a horizontal roof-panel having means defining a plurality of apertures spaced therealong to accommodate an upper portion of each of a plurality of sample vials, (Aii) a horizontal floor-panel, and (Aiii) an upright side-panel connection between said first-channel roof-panel and said floor-panel, said side-panel having a pair of upright planar opposed surfaces including an inner-surface and an outer-surface; (B) a second-channel extending lengthwise from said lead-end to said midpoint and comprising: (Bi) a horizontal roof-panel having means defining a plurality of apertures spaced therealong to accommodate an upper portion of each of a plurality of sample vials, (Bii) a horizontal floor-panel, and (Biii) an upright side-panel connection between said second-channel roof-panel and said floor-panel, said side-panel having a pair of upright planar opposed surfaces including an inner-surface and an outer-surface; (C) at said tray midpoint, hinge means pivotably connecting said first-channel to said second-channel, said hinge means being located at the side-panels of both channels but being relegated inwardly from outer-surfaces of said side-panels whereby said tray can be alternatively employed: (Ci) a stored vials, folded mode wherein the outer-surface of the first-channel side-panel lies alongside the outer-surface of the second-channel side-panel, and (Cii) a vials laboratory analysis mode wherein the side-panels of the two channels extend colinearly in opposite directions from the tray midpoint; and (D) located wholly remote from said hinge means, latch means attached to one channel to releasably latch the other channel into colinearity with the one channel and thereby releasably maintain the laboratory analysis mode for said sample vials tray.
Claim 3
Dependent Claim
27 words
The sample vials tray of claim 1 wherein the side-panels of both channels have means defining ratchetable-openings spaced therealong and for usage during said laboratory analysis mode.
Claim 4
Dependent Claim
42 words
The sample vials tray of claim 1 wherein the first and second channels floor-panels are provided with an array of upstanding springy prongs to removably engage a lower portion of a sample vial, each in vertical alignment with a respective roof-panel aperture.
Claim 5
Dependent Claim
42 words
The sample vials tray of claim 3 wherein the latch means comprises a pair of springy plates including an upper-plate and a lower-plate attached to opposite sides of the second-channel roof-panel and extending beyond said second-channel toward the roof-panel of the first-channel.
Claim 6
Dependent Claim
27 words
The sample vials tray of claim 4 wherein the side-panels of both channels have means defining ratchetable-openings spaced therealong and for usage during said laboratory analysis mode.
Claim 7
Dependent Claim
47 words
The sample vials tray of claim 1 wherein the hinge means comprises an upright bar that is pivotably connected with first-pin means to the roof-panel and floor-panel of the first-channel and that is also pivotably connected with second-pin means to the roof-panel and floor-panel of the second-channel.
Claim 8
Dependent Claim
30 words
The sample vials tray of claim 6 wherein for the laboratory analysis mode a finite gap exists between the colineal side-panels and wherein said upright bar bridges said finite gap.
Claim 9
Dependent Claim
41 words
The sample vials tray of claim 7 wherein the latch means comprises a pair of plates including an upper-plate and a lower-plate attached to opposite sides of the second-channel roof-panel and extending beyond said second-channel toward the roof-panel of the first-channel.
Claim 10
Dependent Claim
42 words
The sample vials tray of claim 8 wherein the first and second channels floor-panels are provided with an array of upstanding springy prongs to removably engage a lower portion of a sample vial, each in vertical alignment with a respective roof-panel aperture.
Claim 11
Dependent Claim
25 words
The sample vials tray of claim 9 wherein the side-panels of both channels have ratchetable-openings spaced therealong and for usage during said laboratory analysis mode.
