My invention is an improved'y container formed without substantial waste from a plurality of nested and adhering blanks forming a box having integral flaps-tor the attachment of a complementary box or closure. Such containers are suitable for the shipment of a great variety of loads, but are particularly adapted for the transportation of ,loads sub ject to injury by shock, blows or'torsional strains. By my improvements, the loads may be readily and securely housed and the package automatically sealed.

In the preferred practice of my invention, boxes are economically and rapidly manufactured from a plurality of laminated blanks cut from boxboard without substantial waste, and either lilled with a loose load or tele scoped over opposite ends of a can orlike load. When colnplementary boxes are used in forming a package, their edges are positioned in abutting relation and the ljoint sealed by projecting integral flaps on one or more of the blanks comprised in the container, so that the package cannot be opened without rupturing, and the load is held against bulging or vibration as well as protected against knocks, blows and torsional strains.

Preferably, a pair of boxes of similar shape are provided with spaced projecting flanges or flaps, and the anges or flaps of one box fit between the flanges or flaps of the comple mentary box so that the edges of the boxes may be brought into abutting relation and are held in such relation by the adhesion of the flanges of one box to the walls of the other box.

The bases of the boxes form non-detachable ends therefor and when the edges of the box` mouth form equilateral geometrical figures a single type of box may be used for both the top section and the bottom section of the container.

In the preferred practice of my invention each end of a blank of substantially rectangular form is slit along parallel'lines for a distance substantially equal to the distance between parallel lines. The blank is scored along parallel lines transversel to the slits at substantially the inner end thereof and is also scored along parallel lines in alignment y Iccirrranvisza 1930.

with the slits and between the ends thereof. If desired, the blank section between the slits may be trimmed transversely to the slits so that the length of their edges along the slits equals the distance between the slits and the edge of the blank.

A blank so slit and scored is bent so that the extensions or flaps of upturned sides thereof lap the trimmed sections between the slits. The parts are preferably held in folded position by a suitable adhesive and one or more of the resulting boxes may be housed within a second blank secured to the boX or boxes by an adhesive and providing projecting flaps adapted for attachment to a Acomplementary box or other closure.

By suitable treatment of the boxboard or of the assembled boxes with sulphur or the like and by the lamination of a suitable number of blanks of proper strength and thickness any desired degree of strength and rigidity may be secured. The exposed edges of the inner blanks form a ledge on which a lcomplementary box or other closure may rest independently of the contents of the container.

The characteristicv features and advantages of my improvements will further appear from the following description and the accompanymg drawlngs of illustrative embodiments theeofl.1 d

As illustrated in Fig. 1, a. substantially rectangular blank of cardboard is scored along lines 1, 2, 3 and 4 to form a square base 5 in the center of the blank. The blank is slit alon theextensions 6 and 7 of the score line 3 and along the extensions 8 and'9 of the score line 4. The length of each slit is preferably substantially equal to the distance between lines 3 and 4.

The slitting and scoring of the blank permits the bending at right angles to the base 5 of sections 10 and 11 forming side walls and of sections 12 and 13 forming side Walls transverse to the walls 10 and 11. The scor-l ing of the blank also permits the bending of flaps 14 and 15 of the section 12 along score lines 16 and 17 to la the sections 10 and 11, and the bendin o? flaps 18 and 19 lie score lines 2O and 21 to lap the sections 10 and 11. The fla s 14, l5, 18 and 19 preferably lap substantial the entire width ofthe walls 10 and 11 whic project above such flaps and the side walls 12 and 13.

As illustrated in Fig. la, a second blank is scored and slit similar to the blank shown in Fig. 1 but with slightly smaller dimens'ions. As it is usually suicient to have sealing flaps projecting from but one of the blanks of a box, the en'ds of the sections 10a and 11a may be trimmed off so that the height of these sections is substantially equal to` the height of the flap 14a, 15a, 18a and 19a lapped thereon.

In assembling the blanks of Figs. 1 and 1a into a box, the blank shown in Fig. 1a may be first bent so that the sections 10a, 11a, 12a and 13a sta-nd at right angle to the base 5a, and the flaps 14a, 15a, 18a and 19a la the outer surfaces of the sections 10a and 11a, the parts being preferably held in position by an adhesive covering surfaces of the parts 10a, 11a, 14a, 15a, 18a and 19a.

rectangular blank p 5b and the walls 12b The carton resulting from the bendin of the blank shown in Fig. la may be placed on the blank shown in Fig. 1 and the parts 0f the latter bent so that the walls 12 and 13 lap the flaps 18a and 15a; the flaps 14, 15, 18 and 19 lap the walls 12a and 13a; and the walls 10 and 11 lap the flaps 18 and 19 and project above the same to form sealing flaps or flanges 22 and 23 projecting above the ledges 24, 24', 25, 25 formed by the edges of the remaining wall and flap members. The parts are secured in position by adhesive between the bottoms 5 and 5a, and on the surface of the members 12a, 13a, 18a, 19a, 12, 13, 14, 15, 18, 19, 10 and 11. The assembled box is subjected to suitable pressure and when the adhesive has set it has a smooth inner and outer surface and is leak-proof.

It will, of course, be understood that if the ends of the sections 10c and 11a are not trimmed oil' these sections will provide additional projecting Iiaps similar to the flaps 22 and 23.

To form a container such as shown in Fig. 5, two boxes formed as above described and as shown in Fig. 3 are abutted so that the ledges 24, 24of one box engage the ledges 25, 25 of the other box, and vice versa, and the sealing flaps 22, 23 of each box may be and are secured by an adhesive to the exterior surfaces of the walls 12 and 13 ofthe other box. Such containers are particularly useful for housing cans making a relative] close slip fit therewith to prevent undue bulging or v1- bration of the can walls. The containers are, however, adapted for the packaging of numerous other products and the contents of one box may be kept separated from the contents of the other box b the insertion of a separator such as the boxboard .blank 26 (shown in Figs. 7 and 8) between the abutting ledges of the boxes.

If desired, the individual boxes may be closed and handled as a unit, as illustrated in Figs. V7 and 8, by placing a blank or flat closure 26 of proper shape u on the ledges of the blank or closure 26. hen the boxes are utilized as individual units, of may be provided with projecting laps 22 and 23 so that the closure will be sealed around its entire periphery.

y improvements are also applicable to the production of packages having several units housed and sealed to form a single container having a lurality of compartments, as illustrated in igs. 9 to 13 inclusive.

As illustrated in Fig. 9, a substantially of boxboard is cut and scored similarly to the cutting and vscoring of the blank shown in Fig. 1a but with the base and 13b having a length equal to substantially twice the width of the bottom 5b between the score lines by which the walls 12b and 13b are hinged thereto. The free edges of the members 12b and 13b each blank there.`

are provided with projections or flaps 226 and 231). This blank is adapted to be combined with two blanks such as shown in Fig. 1a which when folded as before described are positioned with their bases 5a resting upon the base 5b and their flaps 18a and 19a adapted to be engaged by the side walls 12b and 13b. The end walls 10a and 11a of the respective inner blanks are lapped by the flaps 1412, 15b, 18?) and 19b of the outer blank and the walls 10b and 11b of the outer blank lap and the flaps 18b and 19b thereof. The parts are coated with adhesive and subjected to suitable pressure to form a leak-proof box such as shown in Fig. 11.

To form a box complementary to the box shown in Fig. 11, a blank is cut and scored as shown in Fig. 10 similarly to the cutting and scoring shown in Fig. 1, but the length of the base 5c and the walls 12e and 13o is equal to substantially twice the distance between the score lines by which the walls 120 and 130 are hinged to the base. When blanks like those shown in Fi 1a are assembled with the blank shown in ig. 10 inthe manner described in connection with the assembly of the blanks to produce the box like that shown in Fig. 11, there is produced a box similar to that shown in Fig. 11 but with projecting flaps 220 and 230 on the walls 10c and 110. The boxes thus formed from the blanks shown in Figs. la, 9 and 10 may be combined to form a container like that shown in Figs. 12 and 13 with the flaps 2211 and 23?; of one box engaging the walls 12o and 130 of theother box and the projecting flaps 220, 23e of the last named box engaging the walls 10b, 11b of the former box. By securing the flaps to the walls by a suitable adhesive, there is provided a sealed container having therein a plurality of compartments adapted to house either a pluralit of cans or other loads.

Having descri d my invention I claim 1. A container comprising a plurality of nested blanks each having a base section, side sections bent transversely to said base section, side sections aforesaid having aps on ends thereof lapping other side sections of the same blank and the flaps of one of said blanks lapping unlapped side sections of the other of said blanks, and one of said blanks having integral members projectingbeyond the edges of the remaining side sections away from said base, said projecting members being on opposite sides ofthe container and projecting from the outer wall thereof.

2. A container comprising a plurality of boxes having abutting edges, each of said boxes consisting of a plurality of nested blanks each having a base section, each of said blanks having side sections bent transversely to its base section, side sections aforesaid of each blank having flaps on ends thereof lapping other side sections of the same blank and the flaps of one of said blanks a plurality of nested blanks each having a ase section, side sections bent transversely to said base section,

side sections aforesaid having aps on ends thereof lapping other side sections of the same blank and forming therewith a ledge, the flaps of one of said blanks lapping unlapped side sections of the other of said blanks, one of said blanks having integral members projecting beyond the edges of the remaining side sections, said projecting members being on opposite sides of the container and projecting from the outer walls thereof and a closure nesting on said ledge and engaged thereto by said projecting members.

In testimony whereof I have hereunto set my hand this 11th day of June, 1930.

PAUL D. JONES.
