(Cl. 20G-65) 3 Claims.

This invention relates to shipping containers of theY kind comprising an upwardly vopening lower'section and a downwardly opening upper section4 of substantially identical rectangular cross-section disposed with their open' ends in abutting relation and means for securing said sections together. The invention relates more specically to relatively tall heavy duty master shipping containers of the above type that are made of paperboard and are used for shipping in stack formation a multiplicity of relatively small packages each containing a plurality of rayon yarn cones held upright therein in horizontally spaced relation. In some cases, the container is provided with an open ended liner which extends from top to bottom of the container and is provided above the lower container section with a hinged side door through which access may be had to the liner for stacking the packages in the lower portion thereof. In other cases, the liner is dispensed with and the packages stacked in the lower container section and to the required height thereabove, after which the downwardly opening upper container section is telescoped over the exposed upper end portion of the stack and brought into endwise abutting relation with the lower container section. In the first case, the liner 4increases the cost of the container and it is diificult to pack; and in the second case no means is provided for holding the superposed packages in vertical alinement above the lower container section, thereby making it diicult to telescope the upper container section over the exposed upper portion of the stack of packages.

The principal object of the present invention is to dispense with the liner and thereby save the cost thereof and alord ready access to the upwardly openingr lower container section and to provide the lower container section with separate upright members in the interior vertical corners thereof which' extend above said lower container section and position and hold the packages above the level thereof in vertical alinement. These uprightmembers also serve to pilot or guide the uppercontainer section over the upper portion ofthe stack and stiften and strengthen the sides of the container and resist sidewise shifting of the upper and lower sections thereof. Another objectf is to provide cone holding packages in the form of easily stackable rectangular paperboardj,` trays that are provided with means for anchoring the cones therein in spaced upright position.

I The invention consists in providing the upwardly opening lower container section with uptrays and for holding right paper-board corner members of angular cross-section that t in the interior vertical corners of said section and have portions extending thereabove over which the downwardly openingcontainer section is telescoped into abutting relation with said lower section. The invention also consists in providing the container with a series of article containing trays adapted for stacking one on another in and above said lower section and with their corners fitting in the interior angles of said upright corner members. The invention also consists in providing the trays with means for laterally interlocking the stacked the cones in spaced upright position therein; and it also consists in the parts and arrangements and combinations of parts hereinafter described and claimed.

In the accompanying drawings, which form 1. part of this specication and wherein like symstacked mounted in the lower Vtending thereabove with its upper portion held bols refer to like parts wherever they occur,

Fig. 5 is a perspective view of one of the cone holding trays and the cone spacing bottom pad therefor; and

Fig. 6 is a perspective view of one of the upright corner members of the container.

In the accompanying drawings my invention is v shown embodied in a relatively tall heavy duty :shipping container opening lower section comprising an upwardly l and a downwardly opening upper section 2, both of substantially identical rectangular cross-section and disposed with their open ends in abutting relation, the two container sections being preferably made of folded paperboard or other suitable material. The two container sections are preferably held together v`by means of crossed metal securing bands or straps 3 that extend around the container along the top, bottom and sides thereof and are locked in contracted position by means of suitable coupling members 4.

The container also includes separate upright members 5 of angular cross-section which fit in the interior vertical corners of the container and extend continuously from the closed bottom of the lower container section I to theclosed top of the upper container section 2. These upright corner members 5 are preferably also made of folded paperboard and have overlapped horizon;- tal base or foot flanges 6 that are stapled or otherwise secured together, as at 1, and seat on the bottom of the lower container. section I.

Located within the container is a sere'sof coun.- 8 that Vare stacked one` terpart rectangular trays on another from top to bottom of the container with their corner portions snugly fitting in the interior angles of the upright corner members. These trays are preferably also made of VVfolded paperboard and have pesite. side .wallsthereof has. afseries, of relativelyY small circular.` holes extendingl through the bottom prcv-idedV with a oirthe bottom thereof series of.;relatively large circular holes I2 that register with Itherelatively bottomfqfthe tray. Each tray 8 is adapted to. contanalplurality ofiarticles, such as truncated conesy I3 ;of rayon yarn wound. upon tapered spools o`r-cores 14u/hose ends project from said cones. Ther-ayonyarn'cones I3 arepositioned in each trayf with theirlarge Aends seated on the bottom'Y pad-` II nthereinandltheir'small upperends disposed substantially flush with the top edge of said tray andl with the large lower ends of the spools Ofvsaft @Ones fitting in Y bottom pad and the small'upperends of' said spoolsiextending above top. edge` of said tray. Eacwtrmay m'seats onv the` top edgefof Ythe tray .located immediatelyvv upper ends of lowertray; and the small upper ends of the spools I4 of said cones extend into in the bottom of the upper tray. The. topmost trayin hestack is provided with a separate cover pad I5 which is preferably'also madeof Apaper-` boardand seatson top of said tray and the small upper.' ends of theeones I3 rtherein and has relatively snfiallvertical holes IIS adapted to receive the smallprojecting upperends'of the spools' Illy Offs @genes Themaster shipping carton is assembled and paciiedv inY the followingl manner. The upright. corner` members 5Y are positioned in the vertical corners of the upwardly opening lower` container section` I5 and-extend -thereabove with their lapped base flanges 5. seated on the` bottom thereof. The trays 8 with the cones I3 positionedtherein, in thew manner above described, are then stacked one on another in the lowery container section I and above the level thereof until the stack reaches thetops ofthe upright corner members 5. The

cover pad I5 for the topmost tray is then applied thereto,V after which the upper container seccn 2 is telescoped downwardly, over the upright corner members 5Vyinto abutting relation with the upper end of the lower container section I'. The completely packed and assembled container, is then bound with the securing straps 3. As shown in the drawings, the joint between the abutting ends of they two container sections `is located substantially midway between the topand bottomof hand holesS in tworfop-, Each of said trays 8v l thereof and is. pad II of paperboard. orother suitable-material which snugly fits therein andA and has a similar,

The hereinbefore described master shipping container has numerous important advantages. The open tray 8 with the cones I3 held in proper spacedy relation therein are quicklyiand easily stacked oney on another infand.abovev the lower section I and the trays in the portion of the stack or. tier that extends above said lower section are heldin vertical alinement by the upright corner members 'which also serve to pilot and guide the upperlcontainersection 2 when it is telescoped into placed The upright corner members 5 also serve to'stiifer'ifar-1dfV strengthen the vertical corners of the carton and also provide added protectiorifor 'thevertical corners of the trays; and they. also serve to resist relative shifting of the two container sections, such shifting movement being also resistedby the tray locatedopposite th.jlt'thferebetween The cones', I3;.of each, tray 5, are Supported of and ,provide vsupport for the bottom of thejtray seatedonthe upperedge ofthe rst mentioned tray; and thefbctto'm of 'each tray ,provides sup'- port for`r` the'lowerfends of the lspoolsseat'ed in the bottom pad of said tray.
