Victor 7.' Spam Isl I Wm (am Wave; 3m 7 COMBINATION VIAL AND TEST TUBE RACK This invention relates to certain new and useful im provements in portable box-type compartmental and cellular article racks and has to do, more particularly, with a multipurpose vial and test tube rack which has been expressly constructed for expedient chemistry assaying in industrial laboratories and which, because of its unique construction, saves valuable time, space and labor and insures more efficacious mixing consistency of the contained solutions.
Under prevailing practice, vials used for controls, standards, reagents and the like are sequentially lined up and'pipettes drained into them to provide a predetermined amount after which they are inverted one by one. A time clock is then set. At the end of the alloted time these vials are then returned to their initial upright positions and the clock is reset. They are then manually mixed one by one until all of the contents are in solution.
An object of the present invention is to simplify the currently followed tedious and exasperating steps. Where, for example, prior racks can accommodate and house vials of one size only, the innovation herein revealed can be acceptably used with requisite nicety to house 5 ml., ml., 25 ml., and 50 ml. volume vials and also serves to rack test tubes.
The reader, if conversant with the over-all problem and state of the art to which the invention relates is aware that portable boxes, receivers and carriers for racking containers of various types and wherein the receptacle portion is partitioned to provide individual compartments for individual articles are known. For example it can be assumed, broadly stated, that the thermometer rack covered in US. Pat. No. l,474,89l, granted to Mary A. Burt, et al., is exemplary but nonanalogous art. Secondly, the Leo Katz US. Pat. No. 2,759,337, which relates to containers for food and drink and which is used for carrying and cooling of articles for transporting, is of general reference value. Also, and because it is somewhat closer as a citation, the reader may refer to the article carrier of Jack Worthington, U.S. Pat. No. 3,279,648, wherein the bottom wall is provided with apertured well-like bottle seats. However, it is not the purpose here to analyze and explicity compare the present invention with the prior reference patents but merely to call attention to those mentioned for background purposes.
Briefly, the concept herein disclosed with a view toward acceptably solving the problem pertains, generally stated, to a portable invertible multipurpose rack characterized by coordinating and oriented facilities for orderly and accessibly confining a plurality of readily insertablc and removable solution-mixing vials (containers, test tubes or the like) and comprising an open-top box-like receiver. The receptacle portion of the receiver is provided with marginally encompassed interconnected partitions which are arranged in coordinating relationship to define individual open-top article receiving and positioning cells or compartments. These compartments function to accommodate a plurality of containers which are individually pocketed in their respectively cooperable compartments. Readily applicable and removable retainer means is cooperable with and functions for maintaing the containers in given (normally upright) positions. This retainer means also permits the rack to be bodily vials and thus turned upside-down. The containers when thus turned upside down are effectually supported when used in incubated water bath, or alternatively, used outside of the water bath. The compartments are of a size that they lend themselves to feasible use for retentively racking vials of different sizes which are used for controls, standards, reagents and the like.
More specifically, the compartments are of a predetermined size in plan and depth that they lend themselves to practical and safe use for retentively racking vials of different sizes such as for example 5 ml., 10 ml., 25 ml., and 50 ml. volume vials and, in addition, function to rack test tubes of varying sizes.
These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being bad to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:
FIG. 1 is a top plan view of a combination vial and test tube rack constructed in accordance with the principles of the present invention and which is shown as made of transparent material with certain component parts showing through other connecting components and wherein the vials have been omitted for clearness of presentation.
FIG. 2 is a fragmentary detail section showing the small neck-equipped or bottle-like vials (5 ml.) with the stopper-equipped necks extending up through the holes in the first panel and with the second panel covering the stoppers to permit inversion (not shown), taken on the plane of the section line 2-2 of FIG. 1.
FIG. 2A is a view at the right similar to FIG. 2 and which shows basically the same parts with the first or bottom panel omitted and with the second retaining panel fitted into a slot provided therefor.
FIG. 3 is a view taken approximately on the plane of the vertical section line 33 of FIG. 2 looking in the direction of the indicating arrows. 7
FIG. 4 is a fragmentary perspective view showing the notched panel elevated and the cooperating retaining latch in an open position.
And FIG. 5 is a fragmentary view in section and elevation similar to FIG. 3 and showing how the rack can be used to assemble and support test tubes.
With reference now to the views, singly and collectively, the aforementioned box or box-like receiver, is denoted by the numeral 6. This receiver is preferably made of transparent plastic material and comprises a flat self-standing horizontal bottom wall 8, a pair of opposed parallel upstanding longitudinal side walls 10 and a pair of complemental transverse end walls 12. The upper free edges (FIG. 4) of the side walls are denoted at 14. It is significant to note that the upper half portion of each end wall is provided with an upstanding extension which is denoted at 16. These extensions have their upper terminal edges 18 disposed in a common plane as perhaps best brought out in FIGS. 2 and 2A. Each extension is provided with a plurality of horizontal vertically spaced correspondingly performing slots. The lowermost slot is denoted at 20 (FIGS. 2, 3 and 5), the uppermost slot at 22 and the intervening slot at 24. The receptacle portion of the box or receiver is provided with interconnected longitudinal and transverse partitions 26 and 28 respectively which coaet in defining the individual compartments for the insertable and removable containers. The upper edges of the partitions are flush with each other and also with the upper edges 14 of the side walls 10.
Passing over the function of the slotted extensions 16 at this point, attention is now directed to what is here designated as a first horizontal optionally usable panel 30. This panel is generally rectangular in plan and has notched transverse end portions 32. The notched end portions define projecting longitudinal flanges 34. These notched end portions are guidingly fitted over the extensions or end walls 16 and the flanges 34 rest on the upper edges 14 of the side walls 10. Panel 30 is provided with openings or holes 36 which are lined up with the individual compartments and these holes serve to accommodatingly receive the stopper-closed neck portions of the containers. For example in FIG. 2 the small ml. containers are referred to as vials and are denoted at 38. It follows that the neck portions 40 are lined up with and extend into the holes or openings 36, the stoppers being denoted at 42. The substantially flat bottom portions of these small vials are retained in place on the interior surface of the bottom wall 8. In this connection it will be seen that the bottom wall at the lower portion of each compartment is provided with circular concave depressions 44 each of which has an orifice 46 centrally therein. These concave depressions provide seats for the lower convex ends of optionally usable test tubes 48 as shown for example in FIG. 5. Each depression 44 has its marginal portion surrounded by an upstanding ring-like rib 48 which provides a seating retainer for the bottom portion of the vial as shown at the left in FIG. 2. Thus, the apertured depressions and accompanying rings provide proper seating and retaining facilities for the insertable and removable containers. In this presentation it will be seen in FIG. 2 that the various sized vials (four sizes illustrated) are properly accommodated and for best results it has been found that the first panel 30 should be held down in the position shown and this is accomplished by using substantially U-shaped retaining latches such as are denoted at 50 in FIG. 4. The latches are pivotally mounted at 52 and positioned so that the jaw portions swing up over the flanges 34 as best shown in FIG. 3. Thus by latching down the plate 30 this plate assists in properly positioning and retaining the small 5 ml. vials as illustrated at the left in FIG. 2. Panel 30 can be and is used in conjunction with 5 ml. and ml. vials but is not intended to be used for 25 ml. or 50 ml. vials. When, however, it is desired to provide support for the test tubes 48 a second pane (not detailed) but illustrated at 54 in FIG. 5 can be brought into play. The use of the rack for supporting test tubes is significant but incidental compared with the use of a single multipurpose rack for the vials of different sizes, that is, in diam eter and height.
Referring again to the slots 20, 22 and 24 it will be seen that these slots serve to accommodate the insertable and removable second horizontal panel which is denoted for example at 56 in FIG. 2 in particular. This panel has right hand end portions 58 and left hand end portions 60. The right hand end portions protrude beyond the slotted extension and are provided with attached ribs 62 which constitute limit stop abutments and which facilitate in inserting the left hand end portions 60 through the slots, passing the panel over the stopper-equipped vials (FIG. 2A) and then passing the left hand ends through the slots provided therefor and securing the same removably in place. To the ends desired, each end portion 60 is provided with a keeper hole 64 to accommodate an insertable and removable T-shaped keeper or retainer 66.
It is believed that by taking into account the use of the first apertured panels 30 (FIGS. 2 and 3) and the optional use of the second insertable and removable panel 56 it will be clear that the rack serves primarily for the purpose of housing controls, standards, reagents and test tubes and for the purpose of using the rack in incubated water baths when necessary for use in an industrial laboratory.
The insertable and removable and sliding panel 56 is sometimes referred to as a sliding slab and of course prevents the vials from floating to the surface when immersed in a water bath. When used outside of a water bath, as it would be most commonly used, the entire rack is inverted and the slab prevents the vials from falling out. Prior art adaptations cannot be inverted without loss of the containers plus the fact that the rack cannot ordinarily stand upright in an upside-down position when used outside of a water bath. It follows that the extended slotted portions 16 of the end walls serve as supporting legs when the rack is in the upside-down position.
It is submitted that a careful consideration of the views of the drawings, singly and collectively will enable the reader to understand the simplicity of construction of the overall rack and the self-contained features which enable the user to accomplish the improved result desired. Accordingly, a more extended description is deemed to be unnecessary.
The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
