PACKAGE Filed Oct, l0, 1938 Patented Apr. 23, 1940 #UNITED vsTATlazs PATENT OFFICE PACKAGE John- Melvin Freed, Perkasie, Pa. l *Application* October 10, 1938, Serial No. 234,079
. L This invention relates to packages and particularly to a combined package for shipping, displaying and dispensing small planar articles such asmicroscopic slides.
f' In the use of vmicroscopic slides vfor biological and other research' purposes the slides preferred are usually` rectangular in outline and suiiiciently elongated as to be manipulated beneath a microscope. In the ordinary course smears or the like i0 are impressedupon the' surface of a slide, and
the slide placed in operable relation to the microscope for examination purposes and if no more or less permanentfrecord' is desired the slide may be dispensed with or the smear removed for subsequent 1re-utilization of the slide. It frequently happens, however, that for purposes of record it is desired to preserve the smear or other specimen against either contamination or injury and it has become common practice to delicately cover the smear with an extremely thin rectangular or round protecting cover which is caused to be adherent to' the main s'lide in any suitable manner as by adhesive between the slide and cover. In this connection it will be understood that the cover plate mustbe such as to have no adverse optical effect upon the assembly and this necessitates the provision of cover plates of extreme thinness and of consequent fragility.
It is among the objects of this invention; to providev a package combining in a single entity oblong'slides for microscopic purposes and also a package of thin cover plates in mutually guarded relation; .to provide a dispensing pack- 35.- age and slides and cover plates therefore arranged forselectivealternative withdrawal without 'disturbing the other unselected elements; to provide an improved package for microscope slides; to, provide a package containing heavy 4u microscope slides and vlight slide covers with spacing shock absorbing means, and many other objects and advantages will become more apparent as the description proceeds.
In the accompanying drawing:
Fig. 1 represents' a plan of the package of this invention with the cover partially removed to show the relation of the heavy slides, wooden or analogous spacing bar and the fragile cover plates and showing the cover plates as of two grades or relative thicknesses.
Fig. 2 represents an end elevation of the 'package of Fig. 1 but with the cover indicated in dotted lines.
u Fig. 3 represents a longitudinal vertical section (Cl. 20G- 46) online 33 of Fig. 1 but with the cover indicated in dotted lines.
Fig. 4 represents ra perspective of a slide and an associated cover plate as `assembled subsequent to Withdrawal to the package of Fig. 1, Vt5 for instance.
Fig. 5 represents a perspective of a package of cover plates as' wrapped and initially disposed in the package of this invention.
A cardboard shell is provided having a bottom 10 lll, side edge II, rear edge I2, edge I3 and front Wall I4. The side and end Walls are preferably each of a vertical extent substantially the same as the width of the elongated slide elements I5. The slides I5 have top and bottom surfaces re- 15 spectively I6 and I1 connected bythe lateral side edges' I8 and 20 and the length of the slides is such-that edges I8 and 20 are in substantial abutment with a slight clearance relative to the inner surface of the side Walls Il and I3 of the l20 box. I A desired number of slides I5 are mounted transversely in the box with one end of the stack engaging the inner surface of wall I2 while the front end abuts the rear surface 29 of a wooden or analogousl abutment 22 having a front Wall 23 25 in turn engaging the inner surface of the front wall I4 of the box. It will be observed that the block 22, which may be of anysuitable dampening or shock absorbing material other than wood, such as rubber, a molded plastic, or vthe like, is 30 recessed as at 24 and 25. The recesses are separated from the side walls by the solid portions' 26 and 21 and from each other by the solid front Wall portion 28. The recesses 24 and 25 form with the front wall I4 of the box a cover plate 3 5 receiving rectangular pocket or recess Within which a plurality of thin cover plates can be vertically slidably mounted. Illustratively recess 24 receives a plurality of one grade of cover plates as, for instance, the thinner plates 30, vwhile 4.o
pocket 25, hasa different grade of slide thicker cover plates, 3I. It is preferred that there be a slight clearance 32 between the rear surface of the package of thin cover plates and the front Wall of the separating or spacing block 22 at the 45 recesses 24 and 25. It will be observed that the heavy slides resting their full weight upon the block 22, in other positions or attitudes of the box, will transmit their Weight directly to the front wall I4 without` imposing any crushing strains 50 upon the pluralities of thin cover plates.
To facilitate withdrawal of selected slides a pair of registering thumb holes, respectively 33 and 34 are provided in the respective side walls II and I3, so as to facilitate grasping of the side edges I8 and 2D of the elongated slides between a thumb and finger of the user of the package. Similarly, to facilitate withdrawal of the thin cover plates thumb holes 35 and 36 are provided in the front wall I4 of the box in registration with the upper portions of the respective cover plates. In this connection, it will be apparent that the thiclmess of spacer block 22 between the rear wall of each of the recesses 2li and 25 to the slide engaged inner wall 29 thereof is such as to enable the nger of the user of the device to enter sufficiently as to cooperate with the thumb engaging the front cover plate 30 or 3l so as to withdraw same easilyy and quickly if it does not move upward readily enough by frictional engagement with the thumb alone. This latter is the usual operation.
It is customary, although not in any way necessary, to wrapv the individual groups or pluralities of thin cover plates in a transparent Wrapper 31 to form compact units 38 disposed in the appropriate recess 24 or 25 during the shipment and sale of the package. The operator or user of the goods will remove the cover 37 when the package is opened ready for use.
When the lid All, preferably provided with suitable depending walls 4|, is applied to the box all of the thumb holes are covered and the inner surface of the lid 40 is disposed in substantial contact with the longitudinal side edges IG or I1 of the slides l5, and in such close relation to the upper edges of the small cover plate packages as to prevent either the package or individual cover plates from falling'out of the respective recesses 24 or 25 during manipulations of the package.
It will be understood that the clear glass of the slides I5 may be used to enable the observation of printed indicia on the inner surface of the bottom wall I0 of the box and that with the lid removed the package effects an ornamental display of the articles contained in the package and that for dispensing purposes the device provides a single compact unit within which the operator nds eachl of the elements he will need for instant and easy dispensing.
It will be obvious that various changes might be made in the structure disclosed as by changing the number of cover plate sockets, for instance, as by providing more or less than the two illustratively disclosed. Such changes are to be construed as within the scope of the invention unless otherwise specifically limited in the appended claims.
