BOX.

Specification of Letters Patent.

Patented-Nov. 8, 1910.

Application filed January 27, 1910. Serial No. 540,412.

To all whom it may concern:

Be it known that I, JAMES H. CARTER,- citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Boxes, of which the following is a specification.

My invention relates to boxes and has particular reference to the construction of containers or cartons designed for the protection of the contents while in storage or being transported through the mails or otherwise.

The chief object of the improvements which constitute the subject matter of this application for patent is, to provide a .du-

plex or double-walled box for the purpose stated formed of a single piece of sheet material havingcooperating parts so arranged that when properly folded and interlocked, two complete integrally joined boxes will be produced, one of said boxes being contained within and protected by the other.

Another object of this invention is to 'provlde a double-walled container formed rom a single blank that can be produced by a single operation, thus promoting rapidity and economy in the manufacture.

Other objects of the invention are to furnish a .carton formed of a single piece so constructed that the box can be easily and quickly assembled by folding and interfold-v 'ing, and when put together, will combine the desired properties 0 strength, rigidity and light weight to an unusual degree; to furnish a duplex 'or double walled container, in which the outer and innerwalls of sides and top are spaced apart by integral'lugs or cars that project at right angles to the 'wall faces, and to .arrange hinged closures or covers that will permit both boxes to be opened or closed, the outer cover being adapted to interlock with adjacent spacing members thus afiording a secure fastening that will not be likely to be accidentally released, but that may be manually detached to give access to the interior of the box.

particular advantage pertaining to the novel construction of the duplex container herein described lies in the opportunity afforded to utilize both the inner and outer boxes. Thus the chamber between the spaced walls may be filled with a protective material which may be of a nature calculated to withstand pressure or rough usage,= or a non-conductor of heat or cold or a moisture resisting substance may be used, -thus preventing the entrance of liquids into the inner b0x although the outer enveloping wall may be 1n contact therewith. I

I accomplish the desired results by means of the construction illustrated in the accompanylng drawing, which forms a part of this application, the details of the blank and manner of folding and interfolding being disclosed in the following views Figure 1 is a side elevation of a duplex box or carton embodying my improvements,

a portion of the outer wall being broken away to disclose the interior parts; Fig. 2 s a transverse section taken on the line 22 of Fig. 1; Fig. 3 is a top plan view with the outer cover open and the inner cover closed;

Fig. 4 is an elevation showing another side of the carton, with portions of the outer wall broken away; 5 is a plan view of the completed blank. showing the outer face,

and Fig. 6 is a diagrammatic view showmg' the manner of folding the blank to produce a duplex or double box.

The construction of the receptacle will be best understood by referring first to the blank from which it is formed, and designating the various parts thereof, and'thereafter pointing out the particular manner of bending and arranging the said parts so as to produce a finished box. The completed blank composing the receptacle is shown in lar carton, the section 21 being slightly nar-' rower than thesections 22. The fifth section 23 is left at the outer end to form an attaching flap. The sections 22 lie between the sections 21 and 23, .and the section 22 adjacent the section 21 is provided at the ends with the extensions '15, which form closures for the ends of the carton when completed. The portion 7) is slightly narrower and shorter than the portion a, and

is divided in like manner by transverse scores 20 into sections 24, 25, and 26, which form the walls of the inner box or compart- IIlGIlt. There are two of the sections 25,

' precisely alike, arranged between the see- I points between the said lugs as shown, thustions 24 and 26. Arr'anged at spaced intervals and in staggered relation with each other upon opposite sides of the score 'lines which separate the sections from the adjacent sections and from each other, are lugs 27 formed by rectan ula'r cuts 28.- The score lines20 are ma e in the material at leaving the lugs firmly attached to their re. spective sections. As a result of this arrangement, when the sections are folded at right an les along the lines of said scores, the said Figs. 2 and 3. Projecting from the ends of the section 24 are extensions 14, rovided with scores 16*.at the line, of junctlon with the said section, and-adjacent the said scores 3 16 and 16 are lugs 27*, 27', formed in the same manner as the lu 27. The lugs 27 areattached to the section 24, and the lugs 27 to the corresponding tongue 17, so that f when the parts are assemble the said lugs will project at a right angle with the cover. The free margin of the end section 26 is provided with spaced tongues 29. which are adapted when the sectionsare folded to project through similarly spaced slots arranged near one edge ofthe section'24.

To assemble the blank/to form a carton the sections 25 and 26 are bent relatively to each other along their score lines and'the tongues 29 passed through the slots 30, thus forming a rectangular structure or tube 0 en "at both ends. These open ends are t en closed by bendin the extensions 14 along the scores 16, t e tongues 17 being inserted within the cavity 13. The portion a is then folded along the score lines and;

, carried entirely around the said inner recthe corresponding lug 27, unt1l the' said lug enter the slots in the said tongue, thus securing the cover in closed wlth the inner wall an abutting the outertangular structure, the section 23, forming the attaching flap, engagmg a corresponding portion of the outer surface of the sec' tion 21, to which a suitable adhesive 31- is applied, thus binding the entire structure firmly together. The inner faces of the outer walls formed by the sections of the portion a will be held away from the inner walls by the projecting lugs and tongues, as previously explained. One or both of the outer covers are then folded along the scores at their junction with the corresponding section and the tongues .18 passed between the outer ends of the adjacent ton e 29 and tongue an position. l

Having thus described my invention what I claim as new, is-:

1. A foldin box, comprising an inner and an outer wa l, spacin members integral ugs remaining in the lanes of the sections to which they are attac ed will pr o jectoutwardly from the bend, as shown in piece of wall, and closures integral with the inner and outer walls, respectively, some of said closures adapted to interlock with said spacing members,

2. A duplezi .box formed of a single piece of material and comprising two complete boxes, one of said boxes entirely inclosed within the other box and integral therewith,

integral means for spacing the. said boxes 4 apart, integral closures for-the boxes, and integral locking means for some of said closures.

3. A duplex box formed of a single piece of flexible material and comprising an inner box, an outer box completely surrounding the said inner box and integral therewith,

spacing means integral with the inner box,

a plurality of closures for each of said boxes,

the closures of the outer box being adapted to removably interlock with the spacing means on the inner box.

4. A dlgJlGX carton formed of a single exibler material and comprising two complete boxes, one of said boxes con jtaining the other box and integral therewith, means for spacing the said boxes apart, and a plurality of closures for each of said boxes, the closures 'of the outer box being adapted to interlock with portions of the innerbox.

'5. Abox blank adapted to bev folded to form a duplex container, said blank comprlslng two portions having diflerent dimensions, foldable extensions on the larger or- "tions provided with slots, tongues rojecting from one margin of the smallgr portion, and adapted to engage said slots when the blank is folded, spacing lugs on the smaller portion, and foldable extensions on said portlon.

6. A blank for a foldin two connected portions di provided with scores dividing the blank into box, comprising ice ering in size and a series of parallel sections, foldable exten- -sions attached to the ends of one section in each portion, a series of spaced to ueson the mar in of one sectiono thesmaller portion an adapted to enga e slots forme in another section, and lugs formed ycuts made adjacent to the scoresseparating the intermediate sections, said lugs being arranged in staggered relation-upon opposite a1 rectangular receptacles elr centers comcldent. and

of material and comprisin a plurality of I receptacles having coinci ent geometrical centers, integral s acing means between said receptacles, and c os-ures for the receptacles adapted to interlock with some of said spacing means.
