ICE-CREAM-SHIPPING CASE Application filed November 9, 1928.

My invention relates to improvements in ice cream shipping cases or the like, and the object of my improvements are these: First, to supply a heat non-conducting case for an inner removable container, the latter designed particularly for containing ice cream to be kept from melting while being shipped or stored, and the case being padded or otherwise constructed so as to be non-conducting for heat and having removable end caps also similarly made non-conducting, of which the lower also serves as a wear-cap to receive frictional wear during handling or transportation ofthe case, whereby when the lower cap is worn out, it may be readily and quickly replaced without any necessity for discarding the case; second, to provide said lower wear-cap with resiliently controlled means for removably clasping it upon the body of the case, and third, to otherwise improve the construction of the end-caps and body of the case for coact-ion and for proper assemblage, including means for releasably securing the upper cap upon the case.

These objects I have accomplished by the means which are hereinafter described and claimed, and which are illustrated in the accompanying drawings, in which Fig. 1 is a central vertical section of my improved shipping case including its end-caps, and Fig. 2 is an elevation of the same. Fig. 3 is an elevation of the upper end-cap alone. Fig. l is a bottom plan of the case body after removal of the lower end-cap. Fig. 5 is a detail plan View of the annularly connected coiled spring used within and for clasping the lower endcap upon the body of the case, as unten sioned.

My invention is not restricted to the precise construction and arrangement of parts herein shown and described, nor to the various details thereof, as the same may be modified or rearranged in various particulars without departing from the spirit and scope of my invention, one practical embodiment of which has been herein illustrated and described without attempting to show all of the various forms and modications in which my invention might be embodied.

The numeral 7 denotes a hollow cylindrical Serial No. 318,110.

metal container for ice cream or other material to be kept at a desired temperature, said container being closed at the bottom, having an open top closed by -a flanged removable cover' closure 22. 1 is a hollow open ended cylindrical container 'whose spaced walls are closed at both ends to contain in the interspace heat non-conducting material padding 3, which also serves to yieldingly protect the container 7 from abrasions from without. As shown particularly in Figs. 2 and 4, flexible bands 4 and 5 are stitched along the sides of the case 1, ninety degrees apart, to cross the open bottom thereof and there to be secured together as by a rivet 6. A reinforcing flexible strip 8 is stitched around the case 1 near but spaced from its upper end and crossing the upper ends of the bands 4l and 5. Side loops 18 are endwise secured under the strip 8 to serve as handles for the case.

The top end-cap 9 is of the shape of an inverted cup and constructed with an inner wallpart 19 which is cupped upwardlythen directed outwardly to be end-connected to the side wall of the cap leaving an annular lnterspace between the said side wall and the side wall of the cup 19 to receive and fit the upper end ofthe case 1 closely, although there may be a small dead air space left at 21. The interspace of the cup part 19 and the top of the cap 1 is lled with like nonconducting padding 2O to that shown at 3. The bottom of the cupped. part 19 may bear against the looped handle of the closure 22 to retain the latter in place.

The cap 9 may have its side wall split upwardly with overlapped angular flaps 10 and 11 shown in Fig. 3 secured adjustably together by a strap connection consisting of the members 12 and 13 fastened together in the usual way by means of a buckle 14. This permits an easy adjustable fitting of the side wall of the cap 9 over the upper end of the case 1 to be tightly mounted thereon.

' y Opposite the flaps 10 and 11, a vertically positioned strap 15 is riveted to the cap 9 and has its upper end eyedor looped to receive a metal end-ring 16 which serves as a finger-hold while removing the cap. The

strap 15 is secured adjustably by means of a buckle 17 to an underlying strap member, not shown, secured to the case l.

The lower cap 23 is a wear-cap shaped as an upwardly opening cup with flexible textile wall and bottom `parts connected together by stitching or other means, the side wall being a single thickness but having its upper marginn 27 turnedV inwardly and stitched to provide aF"hollo\v l annular `receiving spaceJy for acontained elastic clasping member 28, the member 28 being preferably `a helically coiled spring bent around into a ring with its terminations eyed,,atv 29 and-interlinked together. When the said marginal part of the lower cap is.drawn over the lower .part .ofthe-case l, infthe Voperation the annular spring` 28; has tobe tensioned', to stretch it, then released to againl contract to vclasp the lside wallof the cap23 tightly zupon the case, thesiieXible.paddedwall of which yieldsso that 1.the spring hugs the case frictionally tightlyeandresists :detachment byineans. of anytordinary vforce caused accidentally or due to handling. :'Thefcap 23 may be removed byv stretching the spring enough .to permit the slippingioif of thecap. lt will be'understood thatrlanyother type of annular clasping-means maybe .employed instead of the annular spring 28, withoutfdeparti-ng fromy my infvention.

The bottom .part .ofthe wear.cap-,:28 is a padcomprising. the :spaced ywalls 24 filled with like .paddingv25to that hereinbefore described, -r thefparts,v being end-connected by stitching to each other and to the side wall of thecap 23. rllhexupper and lower.walls 24 mayLbeconnectedtogether by split pins or rivets 26, yheadedpunder the lowerlwall-to serve as wear-heads Y The wear-cap 23is a non-conductor of heat also, and a yieldable pad to receiveY knocks without injury tothe container 7. When the rap 23 is worn out by friction- 'in use, it may be easily exchanged for. a new cap, thus saving thecase lvfor further use, which effects a great economy over types of suchA cases, which must ybe `discarded when their integral lower arts, rare lworn 1 through.

[Itshould be understood that the top cap fastenings 15-17 may be duplicated at the opposite side of theicap 9 ifdesired, to co- ,operatemvith'` -tlie flap .fasteners there, inse- `curing the' cap.

, Havingfdescribedmy invention, .what I claim'asfnewmnddesire to secure by Letters Patent,is:

il. Afdevice ofthe. characterdescribed, comfarising-in combinatioma rigid hollow container, auflexible.casefsurrounding said container, aicupped fleXiblewear-cap .removably ditted uponthe, lower end partroffthe case, saicbwear-cap `having its upper marginal part shapedand secured-together to provide a hollow annularzspringwase aroundy the -Airst- 'the `upper end of said case, andan upwardly cupped bottom padded cap fitted upon the lower end of said case and containing annular :elasticmeans `for clasping it removably upon the case. I

3. lAdevice of the characterdescribed, comprising in combination, a rigid container, a

yflexiblypadded outer casing therefor having openvends, -iiexibly padded caps removably fitted. upon said vopen ends, the bottom cap vbeing elastically clasped upon the casing, the upper cap having a split rim mounted around the casing with overlapped flaps, means for -adjustably securing saidv vflaps together, un-

der ltension to hold the cap in ,placeon the casing, andcther fastening. devicestmounted respectively lupon `the cap and casing opposite said flaps and adjustablyiconnected,together to hold the cap in place against longitudinal separation from the casing while serving as a hinge connection when the yflaps areseparatedvandthe cap swung. open from vthe Y casing.

In testimony whereof Iaifix my signature.
