It is a well known fact that the trend of the dairy marliet has for some time been turning with increasing impetus toward universal use of paper or cardboard containers for milk and cream, these containers being generally of rectangular cross section. However, the means for safely and conveniently handling such containers have not kept pace with the popular adoption of the containers, so that an appreciable loss through damage of the-latter is as yetconsidered unavoidable and therefore expected in the trade. In fact, the general and. unlimited use of such milk containers is partly hampered and delayed for lack of proper facilities for safely handling the containers so that they will ultimately be dlivered to the consumer'intact and with full contents.

One weakness of the delivery cycle with respect tomilk and creamicontainers is specifically that the boxes used heretofore have not been sumciently strong to ,be durable nor designed to pretect the containers effectively. Aside from the mentioned disadvantages remains the further serious and costly trouble of rapid deterioration of the boxes used, as they usually break apart in so short a time that their frequent replacement isan item of heavyexpense with no remedy available on the market.

Having recognized the need for-solving the very evident difficulties thus lying athwart the dairy business, we have now provided a box for holding milk containers of cardboard or paper, which will facilitate convenient and safe handling of such containers without likelihood of the containers being injured or broken. If a carton or container should be injured or actually broken in the box, as is all too often the case in conventional boxes, loss of the product by leakage results. Even if injured or merely weakened in the box, the container is then in such condition that the subsequent handlingof the same after removal from the box, may cause breakage of the container, principally by opening of the seams or joints near the bottom, whereby it will leak and thus lose the product.

One particular evil to which the milk boxes are exposed during transportation is a twisting action or distortion which conventional boxes are not rigid enough to withstand. Such distortion is especially harmful to milk containers, as they fit rather snugly in the boxes, which renders them subject to damage in that they are irresistibly caused to split open at the joints and scams, as already intimated.

Our box, by virtue of its special construction, features and mechanical design overcomes these disadvantages.

The box shown in Figures la, 1 to 9, and 14, comprises a metal bottom 28, having a centrally arranged raised portion 21 formed therein. This raised portion supports one or more of the milk contai'nera-cartons, or bottles in raised position so that their tops project visibly above the other containers whereby they may be conveniently removed, rendering the subsequent removal of the remaining containers easy. This bottom 20 has and spaced inwardly therefrom. This rectangular rib stifiens the bottom and will fit into the open end of a companion box so that the boxes may be stacked. The rib 23 is provided with drain openings 2d and the rib 23 has depending hollow domes i5 formed thereon. The box slides upon these domes, in use, thus taking the wear off of the rib 23, and retaining the drain openings 24 uncovered. The bottom 26 has horizontal longitudinal extensions 26 and these horizontal extencarr'y upstanding vertical longitudinal flanges Formed integral with the metal bottom 20 are metal ends 28, vertically arranged and disposed at right angles to the bottom. The ends of the rib are spaced inwardly from the ends or end plates 28. Each end 28 is stiffened and reinforced by outwardly bulging rib 29, which is rectangular, carries outwardly bulging diagonal ribs at its corners. The rectangular rib 29 affords a space iiii which may be used'as a name plate or the like. At its vertical edges, each end 28 is formed. into vertical channels or sockets 3 I. Each generally U-shaped in horizontal cross section and includes a wide inner side 32, a narrow outer side 33 and an end 34. Each outer side has its free end bent inwardly to provide a locking tongue 35, disposed at right angles thereto. The channels 31 are open at their tops and bottoms.

Each end is extended at its top and bent outwardlyand downwardly, providing a wide inclined plate as, the free end of which is rolled into a cylindrical sleeve 31, the outer face of which is substantially flush with the outer face of the end 34. The plate 36 and associated elements form a handle construction. The plate 36 covers the fingers, protecting them when the user passes the fingers beneath the handle construction, in lifting the box.

In Figure l l, is shown a sheet metal blank'from which the bottom ends and associated elements "e formed. In this figure, the bottom 29 is bent upon longitudinallines 38 to form the inclined portion-s 22 and upon lines 38 to form the longi iii) - boards 46, as shown in Figure 5'.

tudinal extensions 26, and these extensions are bent upon lines to form the flanges 2'5. The rib is between the lines 38 and 38'. The ends {28 are carried by the bottom 20 and are formed by bending the bottom upon the transverse lines dd. At their vertical edges, the ends 28 carry the channels 35, formed by bending the metal .Mes Ali, 32, and 43, forming the inner sides outer sides 33 and ends 34. The blank has transverse folding lines 35', providing the tongues 35. The blank has transverse slits d3 terminating the line 33'. The channels :3! are separate from the extensions 25 and flanges 21. At their tops, the ends 28 are bent upon lines M, to form the inclined wide plates 35, the free ends of which are rolled into the sleeves 37!. These plates are I ate from channels 3!, are arranged betv en them, and contact therewith.

. of hebox are formed of wood. This reduces the weight of the box and eliminates ur clue n in hand}; side is prefered of two if These boards are provided near and inwardly of their opposite ends with verticai gr oves ii, to snugly receive the locking tongues The lower boards 56 are provided upon their outer faces and at their bottom edges with hori ntal rabbets 58 to receive the flanges 2i, and these flanges have their outer facesfiush with the outer faces of the lower Since the bottom 20 is rendered stiff or rigid by the rectangular nib 23 and the longitudinal extensions 26 are also rendered rigid by the inclination of the bottom 2!), there is no tendency for the flanges 21 to spring out of the rabbets it.

In assembling, the boards 55 are moved downwardly into the channels 3i through the upper ends of the channels, until the lower boards d6 rest upon the longitudinal extensions 2%. The sides 32 and 33 have openings 49 and 5!! formed therein, Figure 8, and openings '55 are also formed in the upper boards 46 near their ends. The tubes 52 or connecting elements are Passed through these openings and the sleeves 37, and the ends of these tubes are spread, flatten-ed or expanded, as shown at 53, to draw the sides 32 into clamping engagement with the ends of the sleeves 31 and wide plates 36 and thereby pinch the channels between the latter and tube ends 53. This is an important feature of the invention as it imparts stiffness or rigidity to the box. This feature provides handles of sufiicient strength, to withstand the pull thereon when the boxes are stacked and the handle of the lowermost box is pulled for raising, tipping, or carrying the stacked boxes. Rivets 5d extend through the sides 32 and 33 and the upper boards d5, near their lower edges, and rivets 55 extend through the sides 32 and 33 and the lower boards 35 near their lower edges, in a similar manner to the rivets 5d. The rivets 54 and 55 are arranged longitudinally inwardly of the tubes 52, so that they have a more secure connection with the upper and lower boards 66, Figure 9. These rivets securely lock the upper and lower boards to the channels so that these boards cannot have relative longitudinal movement. The tubes 52 and rivets 5d and 55 retain the tongues 35 within the grooves, and this tongue and groove connection securely holds the channels upon the ends of the boards The upper edges oi" the boards 45 extend for a short distance above the tops of the channels, thus preventing the hands from readily contacting with such upper ends.

In Figure 26, is shown a slight modification of the handle construction. In this figure, the plate 313', corresponding to the plate 36, is vertically curved and extends downwardly, as shown. The same sleeve and connecting element or tube 52 is used. This curved plate 3% and sleeve have clamping engagement with the sides of the channels 31. The elements 32 may be a solid rod instead of a tube. All other parts of the box remain identical with those before shown and described.

In the second form of the invention, shown in Figures 15 to 24, the metal bottom 28 is omitted. Formed integral with the lower edges of the ends 28' are metal bottom sections 56, see [more particularly Figure 18a. These metal bottom sections are provided at their outer edges with transverse inwardly facing channels 5?, the outer ends of which extend beneath the sides 32 and 33 of the channels 3 i. The bottom sections 56 have downwardly'projecting transverse horizontal stiffening ribs 58, terminating at their ends short of the ends of the bottom sections, Figure 16. These ribs 58 are also spacer. longitudinally inwardly of the ends 28. The ribs 58 have downwardly pressed sliding domes 59 and have drainage openings 6B.

The boards 46 constituting the sides 45 are held within the vertical channels 35 and are secured in place by the tubes 52 and rivets 54 and 55. The rabbets 18 may be omitted from the lower boards. The same handle constructions are provided comprising the plates 36 provided with the sleeves 3i, and the plates and sleeves are clamped to the inner faces of the sides 32.

The bottom comprises boards Ell, held within the horizontal channels 5? and secured thereto by rivets 6i, passing through the inner ends of the bottom sections 55 and the boards 60. It is preferred to employ two rivets for each bottom board Gil. The bottom boards have their outer longitudinal edges substantially flush with the outer faces of the lower side boards 46. The bottom side boards to are vertically spaced from the bottom boards 6d for affording drainage spaces 62 and the bottom boards have their inner edges spaced for providing a drainage space 63, Figures 18 and 22. The transverse ribs 58 are spaced inwardly sufficiently from the inner faces of the ends and their ends are spaced inwardly from the inner vfaces of the lower side boards dii so that the ribs 58 may enter the upper end of a companion box, whereby the boxes may be stacked, Figure 22. All other parts of the box remain id cal with those shown and described in connection with the first form of the invention.

As a further modification of the invention, Figures 10 and 11, metal ends 28 are substituted for the unetal ends 23 which are shown in. Figures The top edges of the ends 28 are rolled into beads lid. The tubes 52 are passed through the openings ill, 5i}, and 5E, Figure 11, and serve to connect the channels ti. The sleeves 3i and plates are omitted. All other parts of the ends 28 remain identical with the ends 28' 1 ends 28.

shown and described in Figures 15 to 24.

In Figures 12 and 13, we have shown a further modification of the invention. The numeral 28 designates metal ends, corresponding to the metal The metal ends 2& are slit vertically as shown at 65, and the lower portions of the ends 28 are bent outwardly, forming an upper inclined portion 66 and lower vertical portions 61. The portions 6% and t? are rigidly secured to the This affords suificient finger space beneath the sleeves 31. All other parts of the ends and EbOX remain identical with those shown and described in connection with the first form of the invention as shown in Figures 1 to 9.

In Figure 25, a slight modification of the box which is shown in. Figure 23, is provided. In Figure 25, the lower side board 46 upon each side of the box contacts with the upper face of the bottom board Ell. This is rendered possible by a. notch it cut in the lower edge 68 of the bottom board The side board M5 and bottom board be secured together by nails or the like, desired.

A further modification of the box is shown in Figures 27 to 29. In these figures, the numeral 230 designates metal ends, provided at their vertical edges with vertical channels 3 l corresponding to the channels 3!, Figure 1A. These channels 3 l project outwardly bovond the outer of the ends 280. These channels receive side boards M3, held therein by rivets 41'. The ends 230 are provided at their top edges with inclined plates 35 corresponding to the plate 36, Figure 7, and the plates 36 are provided with sleeves Cili receiving tubes 52 corresponding with the tubes 52. These tubes 52 clamp the inner sides of the channels 3i against the plate 36 and the sleeve 37*. The ends 280 do not have the horizontal channels 51, Figure 23. Each end continues straight to its lower edge, and has lugs Ill stamped therefrom and bent inwardly to assume a horizontal position and arranged upon the inner side of the end 28C. The lugs ill engage the upper surface of a bottom board 60A, and rivets 'H pass through these lugs, the bottom board 60A and a bottom extension l2. This bottom extension is formed integral with the end 280 and is bent at right angles thereto and extends upon the inner face of the end ZdC. Horizontal diagonal hollow stiffening ribs or gussets 73 are stamped from the inner sides of the channels Sl and the ends 280, and serve to render the unit rigid. These ribs or gussets are disposed upon the outer face of the side 2323. While the box sides are shown and described made of wood, this is not intended to form any necessary feature of the invention, as they may be made of any other suitable material, such as various non-metallic compositions, press board or even plastics, if desired. On the other hand, the handle member at the ends of the box is shown hollow in the form of a tube, which is, of course the preferred form, but a solid rod of smaller diameter but of the same tensile strength could be used. Such a rod is obviously too thin to form a convenient handle and is preferably built up to form a comfortable grip by having a tube or sleeve mounted thereon, which is even true of the inner tube shown in several of the views, although the sleeve in most cases is formed of the projecting upper portion of the metal ends of the box projecting out to the handle tube and surrounding the same as a sleeve.

It is to be understood that the forms of our invention herewith shown and described are to be taken as preferred examples of the same, and that various changes in the shape, size, and arrangements of parts may be resorted to, without departing from the spirit of our invention, or the scope of the subjoined claims.
