Y A lfurther object of this invention is toprovide a means for packing frangible articlesV which will be relatively simple in construction, compact, ofpleasing appearance, and very durable in use'.

With these and other objects in view, which will'appear as the vdescription proceeds, there has been illustrated in the accompanying draw,- ings one yform in which the invention may be conveniently embodied in practice. l i `Irv thevdrawings, whereinlike reference nu-` merals designate like parts throughout the severa-l views: t Y 'l Figure l is a sectional View of an opened container, for packages of frangible-,disc-like viiying targets, constituting and embodying the features and principles of this invention; Figure 2 `is a top view of the same; i Figure 3 is a side view of a partition member;

The frangibe` article selected to illustrate the features and principles of this-invention in re:

spect -to an improved means for packing the samev comprises a target similar 'to Ytheftarget shown and-'described in a copending application Serialltlh. 3,718,857 filed February 20, i946). Such forms of targets are generally yfrusto-conical in shape "and, by being hollow and having a vbase rimv Il adapted to -t over a rst vertical'shouh der L2 and rest on the upper surface I3 ofthe base rim Hof a similar target, are adapted to be nested together to form a vertical -pileoftargets as illustrated in Figure '7.- In this instance thirteen targets are shown nested together and in direct contact with each other at their base rims, .but it will be understood that more. or less than, thirteen targets may be so nestedto'- gether in the manner herein shown if it is so desi-red. f' 'f'After' nesting a plurality of v targets together, a narrow band, -or -cord, `of material i4, vsuch as a com-mon rubber elastic ba-nd,vis placed over and about the same from one end `of'the 'pile to theother-:so as to "resi-l-iently and -rmly bind the plurality of targets together and against each other.l --A strip of, :preferably corrugated, cardboard 15,- with the corrugations thereof prefer-i ably onthe inside and extending lengthwise of the package, is then Wrapped transversely about the sides' ofthe pile of nested targets, as indi; cated in Figures 5 and 6. The end edges I6 `and Il of the cardboard strip l5 overlap to some expoints, as at 22, 23 and 24, 25 respectively, to;y

position the pile of targets within and spaced from the ends of the package so formed'. Prefff erably the band I8 is disposed about the package f to lie in these crimped-in portions and to extend,

along one side of the package ,over the overlapped end edges I6 and I I of the strip I5.

is also preferable that one crimped l,portion atv each end of the package be disposed at the overlapping end edges I6 and II of the stripv I'5-to=- form an interlock between these ends to assist in preventing this strip from unwinding. As shown, it is preferable to vstart 'the bent, or crimped-in, portions 22,v 23 at the top edge 26 of the uppermost target of the pile, and to start the bent, or crimped-in, portions 24, 25 at the bottom edge ofthe base rim, or bottom, II, of the lower-most target of the pile so that the pile of targets will be held between these crimped-in portions and be spaced from the protruding ends I9 and 2| of the package so formed.

By so packing a plurality of nested targets, each directly in contact with the other, a pack.-` age is formed which, in this instance, is cylin- -`adjacent end of the container.

locking partitions 38 and 39 of corrugated cardboard with the corrugatlons disposed vertically in respect to the packages, which form vertically disposed pockets 4I in which the packages of targets are vertically slipped, and the Walls o1' which rmly engage these packages of targets. The lengthwise partitions 38 extend at each of their ends beyond the cross-wise partition 39 adjacent thereto to snugly engage against the The cross-wise partitions 39 likewise extend beyond the length- .'fwisel partition38 adjacent their ends to snugly engage against the adjacent side of the container. .-Thisconstruction forms a protecting space 42s`urrounding-V the packages of targets between e the partitions 38 and 39 and the ends 28, 29 and thesides 3I,-32 of the container, and the partidric'al in form, and has its ends I9 and 2| spaced Y from the respective upper and lower-most target of the nested pile thereof, whereby the end targets are protected against contact with any other article when the package is seated on either of its ends, and are also protected against contact with any surface upon which the package may be dropped, and the inner targets of the pile are relieved from shattering shocks which might be imposed upon the package. Due to the provision of a rubber elastic band I4 about the nested targets and that the cardboard strip I5 while tightly wrapped thereabout'frictionally engages this band I4. an added means Ais provided to resist endwise slipping of the pile of targets in respect to its wrapper. the cardboard strip I5. "Ihe provision of a rubber elastic band I8 to constantly and resiliently urge the crimpedin portions of the wrapper, or cardboard strip I5 into tight engagement with the targets enfolded thereby, insures that no side slip will result between the wrapper and the targets or between the targets themselves, but will allow some expansion of either, or both, of these crimped-in portions lengthwise of the package to absorb any shocks imposed thereon when the package is dropped.

After packaging each pile of nested targets as above described they are disposed in a container illustrated in FiguresV l-4 inclusive, and which comprises a rectangular box. preferably made of corrugated cardboardv and having ends 28, 29, sides 3I`, 32, end cover and bottom aps 33, 34, side cover and bottom naps 35, 36, and a sepa-A rate cover and bottom end flap spacer 3'I. The end cover and bottom flaps 33 and 34 with the spacer 3l form a flat inner surface and with the side cover and bottom flaps 35, 36 which abut at the center form a double thickness wall of corrugated cardboard at the top and bottom of the container.

The container also includes two sets of intertions 38'a'nd 39 reinforce the container sidewise "'The sets of interlocking partitions 38 ande39 are superimposed one above the other, being sep'- 'arated by a loose horizontal partition 43, also of corrugated cardboard with the corrugatlonsrdi'sposed transversely across it, upon which the upper plurality of packages are seated; When filled with packages of targets, the container is closed at its top by the respective cover flapsV and suitably sealed with gummed paper disposed along the jointure of the abutting side flaps 35', 33. When closed, the container, due to the ver--y tical reinforcement of the partitions which,` with the' horizontal partition 43, extend betweenl vthe top and bottom cover parts and arer engaged thereby, resists crushing forces to protect the packages of targets therein. When again opened, the rst layer of packages of'targets may be re'- moved intact. one at a time, without disturbing the others. Preferably, and to insure that th packages of targets do not slip lengthwise-in the pockets 4I, theheight of the partitionsl 38 and 39 is substantially equal to the height ofthe packages from one `end I9 to the'other end l2| thereof, so vthat these package ends will be en` gaged by the top or bottom double wall ofl th container and the horizontal partition 43far1d firmly held in place. 'fj

By means for packing frangibl'e 'articlesas above described, a plurality of the articles',l in

this instance the disc-'like flying targets II,`are

walls 'and the'partitions therein before the pack-J ages are effected thereby and then by the pro-y truding ends I9 and 2l of the packages.` While there has been shown and described hereinone means for packing frangible artiJ cles, it is to be understood that the inventionA may be embodied in other forms without depart` ing from the spirit and essential attributes thereof. It is therefore desired that the present embodiments be considered in all respects asl illustrative and not restrictive, and it will be further understood that each and every novel featureA and combination thereof, present in, or possessed by, the means herein disclosed, forms a partof the invention included in this application.

What is claimed as new and for which it is desired to secure Letters Patent, is:

l. Means to package a plurality of frangible articles'nested together in contact with each other in the form of a pile, a band of material 10 extending lengthwise about said pile of articles, a wrapping of crushable material, such as corrugated cardboard, wrapped transversely about aboutg'the wrapping and disposed between the 20 upstanding portions and upon the bent over portions to hold it about the pile of articles and to suspend said articles between its ends.

2. Means to package a frangible article comprising a wrapping Vof material encircling the article with its side edges overlapped and having end portions extending beyond the upper and lower ends of said article, said extending end portions being crimped inwardly against the peripheral edge of the adjacent end of said article at peripherally spaced apart points, one of the crimped-in points being disposed at the overlapped joint of the side edges to interlock them the remaining portion of the extended wrapping ends being left projecting beyond the crimpedin portions to protect the article against endwise shocks, and means to resiliently press the crimped-in portions of the wrapping at both ends of the article against the adjacent end thereof.
