i sirable feature in View ofthe huge sumsl expended by bottlersl in establishing a distinctive bottle. The novel portable can carrier or` pack of' this invention has the desirable feature of displaying the distinctivecan label in addition to being readily loadedby machine.

The. portable cancarrier or pack of" this. invention is made from al single blank; Solid sections" constituting a part' of! lthe top and bottom of said'lcarrier` in'. loaded position are connected' to' one another' by af plurality4 of panels and struts. Advanta'geously,.the carrier conta-ins a carrying handle which is simply formed from the top section; a crease is placed in the top'section and; the handle is formed by bending a portion of the' top section at `right angles. The plurality of panels and struts which connect the top and bottom sectionsl are in hinged relationship thereto; the struts are medially positioned between two panels. Each panel consists of a' strip and hinged ilaps attached to said strips'l in hinged relationship; these aps can be bent fromfthe plane of' the' strips along the'hinges and are designed to hug a canlin the carrier;l The panels and struts are creased laterally'at positions deningthe top and bottom rims'ofy the' can tobe inserted in the carrier. The portions off the panelsl'ocated between said topand bottom-delining creases and the hinges connecting the panels withI the top and" bottom sections of` the carrier form part ofthe top and bottom of the carrier'in loaded position. In the' panels' the strips gradually' widen and the apsdiminish in'w-idth' a' corresponding amount in the portions of' the'panels'forming part of' the top andl bottom ofv the carrier' in loaded position?. Each can receptacle is dened'fby' two panels and a strut; the panels engage the' sides' of the can and the strut engages the back of the can and prevents rearward motion of the` can.

The portable carriers' of this invention are loadedY by bending each can receptacle' and insertingv a can into the receptacle while the panels `are spread by the. circular distortion of the carrier. When the carrier revertsl to planar position, each can' is snugly held bytwo panels and a strut. The strips' confine' the outer portion of the, can whilel the liaps snugly'l hug the side of' th'e can; a strut confines the can in thev proper position' by acting asl a support' for'the back of the can; Advantageou'sly, a carrier'unitin unassembled position is passed along a belt and formed'. As eachsuccessive can receptacle, that is, the space defined by two panels' and a strutV is bent out of planar' position, a can is inserted therein.l A clearer picture of the novel manner of loading' the carrier or pack of' this invention willbe apparent from the detailed 2,889,957. Patented June 9, 1959 description and drawings which will be presented hereafter.

The carrier is characterized by a plurality of advantages which make it outstandingly superior to available portable can carriers. The carriers of this' invention possess merchandising attractiveness, structural strength and compactness in addition to their readyadaptability to machine loading and economic preparation vfrom one strip of.'` box board.

Since the carrier of this invention displays theflabels of! the cans, as has been indicated previously, it is an aid to merchandizing. The color scheme of the carrier can be blended with the distinctive color scheme` of the canned merchandise so that the combination of carrier a'n'dldisplayed-y can is avery effective sales promoter.

The carrier or pack makes a compact unit so that a' plu"- ralityV of units may be loaded into packing cases for transportation ofwholesale lots. This feature of the container permits simple delivery of` multiple units from the packaging house to wholesale distributor and then to the retainer.

Another outstanding feature of the novel can carrier is that its structure allows the use of lighter paperl in its manufacture. The outstanding structural strength of this carrier derives from the fact that shock is absorbedby contiguous cans rather than bythe carton or a portion thereof.

The major advantage ofthe carrier or pack of this invention is its adaptability to machine loading. Time con'- suming and expensive hand loading is antiquated'by the use'of this carrier. Cans are inserted in the carrierv as it passes along a belt; as' each opening, which is framed by' two panels and a strut,.is distorted out of a straight plane, a can is inserted therein'. When the carrier reassumes a planar position, the inserted cansV are tightly and securelypositioned in` the carrier; eachcan is bound on either side 'by the strip portions' of adjacent panels; the flaps of adjacent panels snugly embrace side surfaces of the can and a strut outlines the back of the can thereby preventing movement away from the supporting strips and aps;

A further advantage ofx the novel' carrier of this in; vention is that' it can bev constructed of less paper than previously known carriers. Because of the inherent strength of the carrier, it can be made' from light weight box board. Inv addition; a carrier can' be prepared from a single strip of box board by relatively few operations which comprise merely printing, cutting and creasing. The simplicity of preparation of' this carrier willl be ap'- parent when theV accompanying drawings' are discussed in detail.

This invention characterized by' its' novel mode ofmachine loading and its feature of displaying the canned merchandise can be used either' in the form of carriers whichpossessv handles or in the form of packs which do notl possess a handle. Beer and canned juices are particularly suited for packing in carriers. A preferred carrier is of the suitcase type wherein the cans are introduced intothe carrier in'open position in double' rows and is then folded like a suitcase -to form a double row of can'swhose backs are adjacent' to one another. Other canned goods, such as frozen fruit concentrates, are par'-' ticularly adaptable tomerchandizing in handle-less. packs containing two or more cans` In the packs a row-fof cans is backed by a solid'section of box board rather than byan identical assembly of cans;

IntheV accompanying drawings there are shown various views of the novel can carrier. These drawings` will visibly demonstrate the superior features of the carrier of this invention. Figure l is a planar view of the preferred' suitcase type carrier as it' appears in: unassembled position prior to loading; Figure Z-is` aperspeotiveofart unloaded carrier which has been folded into its normal configuration; Figure 3 is a side elevation of the carrier loaded with cans. Figure 4 is an end elevation of the loaded carrier along the plane 4 4 of Figure 3; Figure 5 demonstrates how the carrier is loaded by angular distortion of the carrier resulting in spreading of the can- .cngaging panels.

Figure l is a View of an unassembled suitcase carrier. .The two portions of the carrying handle are designated .by 1 and 1. The top, 2 and 2', of the carrier comprises a solid top section 3 and 3 and the parts of the panels and struts of the carrier falling between the hinges 4 and 4' and the creases 5, 5'. The sides 7 Vand 7 of the carrier comprise those portions of the panels and struts falling between the top defining creases 5, 5 andthe bottom defining creases 6, 6. The bottom 10 of the carrier comprises the bottom section 11 and the portions of the panels and struts falling between the bottom dening creases 6, 6' and the hinges 12, 12. The panels 14, 14 comprise flaps 15, 15 and strips 16, 16'. The dotted . lines 17, 17 designate the creases which connects the strips and aps in hinged relationship. The struts 20, 20 act as a support for the back portion of the can. The solid lines 21, 21 designate the cuts by which the struts 20, 20 are separated from the panels 14, 14'.

It is apparent from an inspection of Figure l that the carrier of this invention can be manufactured from a single strip of box board. Ihe only operations involved in its manufacture from a single strip are printing, cutting and creasing.

Figure 1 is also representative of the open position in which the carrier is loaded. The carrier in open planar position is formed by hand or machine into a unit having a can receptacle and passes along a belt; as the carrier is distorted from the planar position two cans are fed into the two horizontal receptacles passing through the area of maximum distortion; thus the carrier is loaded two cans at a time until the unit is lled. When the unit is filled, the open carrier is folded like a suitcase along hinges 12, 12 adjacent to bottom section 11 of the carrier. The carrier can be locked in assembled position by staples or other conventional means locking together handle sections 1 and 1'.

Figure 2 is a perspective of an empty carrier which has been folded into the configuration it possesses when loaded. It is apparent from Figure 2 how the struts 20, 20' confine the cans and prevent backward motion thereof. It is also apparent how the strips 16, 16 and aps 15, 15' snugly contain the sides of each can. It is further apparent from Figure 2 how the top of the carrier in assembled position comprises top sections 3, 3 and portions of the panels and struts falling between the hinges 4, 4 and the creases 5 and 5. The bottom of the carrier 10 comprises solid bottom section 11 and the portions of the panel and struts falling between the bottom-defining crease 6, 6' and the hinges 12, 12.

Figure 3 is a side elevation of the loaded carrier. The cans 30 are clearly visible outlined by the Strips 16. It is apparent from Figure 3 that the close juxtaposition of the cans absorbs the shocks which the carrier is subjected to in normal usage. Figure 3 also illustrates the value of the carrier of this invention as a merchandizing aid. It is apparent that a distinctive can marking is clearly visible.

Figure 4 is an end elevation of the loaded carrier along the axis 4-4' of Figure 3. It is clearly apparent from this figure how the struts 20, 20 confine the cans 30 in their designated place in thecarrier. Moreover, it is apparent there is no undue strain on struts 20, 20' because of the close, substantially contiguous position of the cans. The major portion of any shock is not taken by the struts but by the cans which they confine.

Figure 5 shows how the carrier of this invention is simply loaded. Angular distortion of the carrier from planar position results in separation of the panels 14 comprising strips 16 and aps 15. In the drawing the major 4 amount of angular distortion is realized at the points 28 on the top and bottom of the carrier on the top hinge 4 and bottom hinge 12. The can 30 is inserted in the opening between the panels 16 while the carrier is in the spread position. As the carrier reassumes its normal plane of position, the can 30 is confined in its receptacle between strut 20 and between flaps 15 and strips 16 of each panel. It is apparent from this gure that the carrier can be readily loaded by machine.

Although the carrier of this invention has been illustrated with conventional flat top cans, it can also be employed for cone-top cans. All that is required to adapt the carrier to cone-top cans is a slight rearrangement in the positioning of the creases at the top of the cans. The creases in the struts are placed higher than the creases in the accompanying panels to adapt the carrier to conetop cans. Thus referring to Figure l the carrier is adapted to the use of cone-top cans by staggering the creases 5 and 5'; the creases 5, 5 are made higher on the struts 20, 20' than on the strips 16, 16' and aps 15, 15' of the panels 14, 14.

Y The invention has been described as adapted for a unit of six cans. It is apparent that the carrier is adaptable to use of either more or fewer cans per unit.

The description of the can container of this invention has been entirely devoted to suitcase carrier. It is reiterated that the invention is equally as well suited for handle-less packs. A pack would utilize but half the unit shown in the aforesaid diagrams; the row of cans which serves as a backing in the described suitcase carrier' would be supplanted by a solid section of box board. In addition, the pack does not contain a handle.

The pack-type carrier is illustrated in Figures 6 and 7.

Figure 6 is a view of an unassembled pack type carrier while Figure 7 is a perspective of an empty pack-type carrier. In both these gures the top 35 of the carrier comprises a solid top section 36 and parts of the panels 45 and stints 50 of the carrier falling between the hinge 37 and the crease 38. The bottom 39 of the carrier comprises a bottom section 40 and the portions of the panels 45 and struts 50 falling between the bottom-defining crease 42 and the hinge 41. The panels 45 comprise strips 46 and aps 47. The crease lines 53 connect the strips 46 and the aps 47 in hinged relationship. The struts 50 are separated from the panels 45 by the cut score lines 52. The back 55 of the pack-type carrier is connected to the bottom of the carrier 39 by the crease line 57. There is attached to the back 55 a glueing tab 56.

It is apparent that the novel carrier of this invention can be used with other cylindrical containers as well as with cans. For example, the carrier of this invention serves well in the packing of two or more glass jars.

Obviously many modifications and variations of the invention, as herenbefore set forth, may be made without departing from the spirit and scope thereof, and therefore only such limitations should be imposed as are indicated in the appended claims.
