3 Claims.

'Ihe invention relates to cartons and particularly those of the type used for transporting beverage bottles.

In the past cartons of the type mentioned have been made of cardboard and the like, which material has the advantage of reduced cost and a considerable saving inwweight over previously used wooden cases. However, such cardboard cartons have the disadvantage that they are lacking in strength, and hence are apt to be crushed when a number of lled cartons are stacked one upon another, or injured during handling because of the weight of the contents. Accordingly it Ais the general object ofthe present invention to provide an improved composite cardboard and metal carton, in which the sheet metal portions are so arranged as to materially strengthen the carton without materially increasing its cost.

A further object of the invention is to provide 20 a composite cardboard sheet metal carton in which the cardboard portions may be readily replaced as they wear.

Other objects and advantages of. the invention will become apparent from the following specication, the accompanying drawing, and the appended claims.

In the drawing wherein like numerals are applied to like parts in several views;

Fig. 1 is a perspective view of the carton in a partially closed condition.

Fig. 2 is a horizontal section taken along th line 2-2 of Fig. 1. i

Fig. 3is a longitudinal section taken on the line 3-3 of Fig. 1.

Fig. 4 is a longitudinal section similar to Fig. 3 but of a modified form of the invention.

Referring to the drawing, the main body of the carton is formed of a substantially rectangular blank of. cardboard, or the like, such as commonly used in the manufacture of cartons. The blank is provided with a plurality of parallel crease lines which divide it from end to end into a top ilap I I, a half top member I2, a side panel I3, a bottom member I4, a second side panel I5, a second half top member I6, and a second top nap member I'I of the carton. It will be observed that these portions constitute the entire carton with the exception of the end members, and that they are formed of a single substantially rectangular sheet of material, thus avoiding waste and providing an exceedingly simple means for forming a carton.

The carton is completed by a pair of identical end members or walls I8, only one of which will be described in detail. Each end wall I8 is pro- Cil 1936, Serial No. 107,330

vided with a pair of side channels indicated generally at I9 and 20, and a bottom channel indicated generally at 2l. The channels I 9, 20 and 2| are substantially identical to each other and as shown best in Figs. 2 and 3 comprise an out` wardly extending ilange 22 integral with the main body portionv of the end member I8 which forms the inner side of the channel. The material of the end member is then turned outwardly at 23 to form a bottom for the channel and thence inwardly at 24 to form the outer side of the channel, thus providingan inwardly opening channel adapted to receive the ends of the side and bottom walls of the blank III. The channels are so formed that the end member I8 may be assembled with the remainder of the carton by simply sliding the ends of the side and bottom walls into the channels IS, and 2|.

In addition to the side and bottom channels the end members I8 are provided with top rein,- forcing channels 25 which are similar to the side and bottom channels previously described. It will be noted that the side walls I3 and I5 extend outwardly of the upper end of channels I9 and 20 through openings or gaps 26 at the upper ends of the top and side channels, and that the half top members I2 and I6 when in closed position overlie the outer surface of the top channel 25. The top iiaps II and I'I are shorter than the half top members and are adapted to project into the interior of the carton between the end members I8 when the top is closed. Preferably the proportions oi the parts are so chosen that there will be sufficient friction between the end members I8 and the edges of the top iiaps II and I'I to hold the top members in closed position.

After the end members I8 are assembled with respect to the side and bottom walls of the container, a plurality of longitudinal and transverse partition members 3i and 32, respectively, are positioned within the box to divide it into a plurality of bottle-receiving sections. These partition members are interlocked together in the usual manner to provide a honeycomb arrangement, and end pieces 33 are provided to prevent contact between the bottles and the sheet metal end members I8. After the end members I8 are assembled and thehoneycomb partition members 3l, 32 and 33 are placed in position, a bolt 28 is inserted through aligned holes in the end members I8. The bolt 28 is provided with a head 28 and a nut 30 for retaining the end members against accidental displacement from the container. It is apparent, however, that when desired, the nut can be removed and the blank I8 released from the channels I9, 20 and 2| of the end members.

In Fig. 4 is shown a modied means for soeuring the end members in position. In this form of the invention the structnre of the container 5 is the same in every1 respect with that previously described except that the end members are provided with inwardly extending perforated tongues 4I and a rod 42 having downwardly extending end portions 43 is inserted within the box with the end portions 43 received within the periora tions of the tongues 4|. The bent-over end portions 43 of the rod 42 are preferable bent slightly more than 90 from the axis of the rod in order that they will have to be bent apart slightly to i5 be inserted within the apertures. 'I'his prevents accidental'displaceinent of the rod without interfering with its removal when such is desired.

It is apparent that in accordance with the present invention there is provided an exceedingly 20 inexpensive carton which is of great strength. In use these cartons are frequently stacked one upon the other to a relatively great height with the result that considerable pressure is applied upon the lower cartons. In the present invention 25 this weight is sustained entirely by the sheet metal end members which are of sufficient strength to withstand relative heavy loa-:is and -tlnus the weaker card board sections are protected from injury. In addition the form of the 30 end members is such that they are materially reinforced by the channel members and the channel members being extended outwardly of the box provide a suitable means by which the box may be lifted. Thus thebox can be readily lifted 35 by placing the fingers beneath the uppermost channels of the end members, and this can be done regardless of the position of the bex. The upper channel 25 is of course not necessary but it is preferably provided to reinforce the end mem- 40 bers and to provide means for lifting the container. If desired a suitable hand hole may be provided inmediately below the central portion of the top channei 25 but such is not necessary as the channel itself provides suicient means for 45 engagement by the hand of one who is desirous of lifting the container. When the card board portions of the carton become worn or injured they may be replaced without any difiiculty.

While only two forms of the invention are disclosed herein, it will be understood that other modicatior: s may be indulged in within the spirit of the inventionas set forth in the above specification, and as iilustrated in the drawing, and within the scope of the appended claims.

What I claim is: f

1. A composite carton comprising card board side and bottom walls, and a pair of sheet metal end wall members having peripheral 'channels adapted to receive the ends of said side and bottom walls, said end wall members having inwardly projecting perforated ears formed thereon inwardly of the channels, and a tension rod having bent-over end portions inserted in said apertures for releasably holding the end wall members in position.

2. A composite carton comprising a pair y of sheet metal end members each `saving peripheral vchannels formed at the four sides thereof, said channels opening in a direction perpendicular to the plane of the end member and havingtheir side walls projecting in the opposite direction from said plane, a bottom wall having its ends received in said channels at the lower edge of the respective end members, cardboard side walis having their ends received in the channels at the sides of the end members, a cardboard top member integral with one side member and adapted tok swing ,into contact with the outer sides of said channels at the top of said end members, respectively.

3. A composite carton comprising a pair of sheet rnetal end members each having peripheral channels formed at the four sides thereof, said channels opening in a direction perpendicular to the plane of the end member and having their side walls projecting in the opposite direction from said plane, a. bottom wall having its ends received in said channels at the lower edge of the respective end members, cardboard side walls having their ends received in the channels at the sides of the end imembers, means urging said end members toward each other, a cardboard top member integral with one side member` and a tab on said top wall adapted to extend int-o the carton when the top is closed and to t snugly between the end members for maintaining the lid closed.
