BOX .AND METHOD or MAKING THE sum.

7 Application filed February 2, 1922, Serial No. 533,624. Renewed August 5, 1924.

The present'invention is an improvement upon the method and box structure disclo2sed in my Patent No. 1,408,4t7 9, March 7, 19 2.

According to that disclosure blank as- I semblies are produced by what I have described as a, continuous method, or in some cases they may be otherwise produced, and these blank assemblies are so formed that when they are folded into box shape and properly secured they present a. close approximation in appearance to the highest class of covered boxes, the inner 'peripheral margins of the shellwalls being covered by an overlapped marginal portion of the cover sheet, and all exposed walls and edges of the shell material being concealed by the cover paper, with the exception of certain edges of the shell end wings which are left more or less exposed. V

While boxes having the described characteristics are suitable for many purposes, the presence of exposed shell edges renders them undesirable in cases where the highest possible finish is desired. The object of the present invention is to provide modifications and improvements in the above mentioned method and structure, so that boxes previous structure may be produced, but

- with the important difference that the shell end wing edges as well as all other exposed surfaces and edges of the shell material are overlaid and concealed by the cover blank.- The present improvements are also devised so that the boxes may be produced when desired, by a continuous production method generally conforming to the method disclosed in the above identified application, with improvements for the present purposes, as sufficiently described hereafter.

The accompanying drawings show certain exemplifying embodiments Ofthe invention. After considering these persons versed in the art will understandthat many modifications may be made within the principles of the invention, and I contemplate the employment of any method of production and structures which are properly within the scope of the appended claims.

In the drawings:- I Fig. 1 is a perspective and largely diagrammatic view, explanatory of the continuous production method.

Fig. 13 is a similar view of a'box made from an assembly like Fig. 11.

In accordance with the'continuous assembly method (Fig. 1) a continuous stri of shell material W, usually card boar of suitable grade and thickness, is advanced from a suitable source of supply, such as a roll (not shown) and during its advance at a suitable point is provided with longitudinal creases or score marks 12. At a suitable point in the advance of the shell strip, apertures are punched in it by suitable cutting or punching devices, and this punchin as may ota may be done in one or two stages. e convenient, the punchlng operations, however performed, resulting in the formation of major transverse openings a, of substantially rectanguar form. Rectangular enlargements b of these openings are also provided, resulting in the resent specific embodiment in a substantial y H -shaped Opening of which the margins c are usually substantially in line with the longitudinal score'marks 12. These .apertures define the I shape .of the shell end wings when the blank assembly is completed. I

At a suitable point in theadvance of the shell strip it is brought into association with a continuous strip of cover material X which,

may beadvanced from a roll B andis ad hesively conditioned Onthe surface which is to erigagethe shell material, a glue roll 5 being shown to exemplify means for applying adhesive to the cover strip. The

cover strip is brought in contact with they 1. The apertures of the shell leave exposed the adhesively coated cover material, readyfor subsequent box forming operations.

Successive portions of the continuous assembly are .then severed along the transverse individual blank assemlines 15, producin imilar assemblies may-be blies A, Fig. 2.

also produced by association of properly formed shell and cover blanks assufliciently explained in the reviously identified application. The in ividual blank assem 1y,

however produced, in the present representative form, comprises a piece of shell material including a body portion 20, side wings 21', corner laps 23 extending from the ends of the side. wings, and end wings 22. The outer or under'face of the shell is covered by the cover material which includes portions corresponding generally to the parts of the shell blank above described,

and identified by the same'reference characters with the addition of a prime mark. Margins a: of the cover are-turned over and secured to inner marginal portions of the shell along the outer edges-of the side wings and corner laps. The'shelllend-wings are soformed that a stripor margin 1 portion of the cover end wing 22 extends beyond.

theshell end wing about all of its free sides,

and this marginal portion of the cover ma terial is provided with adhesive which may have been applied during the continuous assembly operations as above described, or

- may be otherwise applied inidifierent ass'embly methods. The side margins 26 of the shell end-wings are located inward considerably from the adjacent edges of the cover end wings, for reasons later'described.

a suitable point in the box-,'formation operations, and in some cases before the individual blank assemblies are severed from the continuous assembly, cuts are made along the lines 24, severing the cover material along hnes corresponding to the inner Ion-- gitudinal hues of the shell corner laps '23.-

In oneway of forming the cuts 24, they I may be made' at;the same time that the transverse severing cuts '15 .are'made,

s ntably formed cutter or knife. j The assemblyis now folded up into, box

manner corner laps at a suitable point in the assembly operations are provided with adhesive 25, and this application may be made while the blank assembly is still in flat form, as shown in Fig. 3, or at any convenient later stage up to the time of lip-folding the assembly end wings.

Fig. 6 shows the assembly end wings folded up against the corner laps, the shell end wings 22 being pressed against the adhesive surfaces 25. The material of the cover end wings 22' extends beyond all the edges of the shell and the outer marginal portions of the cover end wings are pressed against the outer surfaces of the corner laps and firmly secured. The upstanding marginal portions 2 of the cover end wings are then turned in and adhesively secured to inner end wall surfaces and the box part is then complete as shown in Fig. 7.

The apertures b in the shell material are shown of considerable width in Fig. 1, largely-for the sake of clearness of illustration and While, of course, the apertures may be so made, resulting ill-the edges 26 of the shell end wings being located considerably inward from the sidewalls ofthe box, these edges may otherwise be located much nearer tion method asshown in Fig. 1,'the ape'r:

tures b will be made correspondingly narrow. Fig. 9 shows a completed box part made from the bIankmf Fig. '8, showing that the marginal portions k of the-cover end wing material. extending beyond the shell edges 26 may. be quite narrow, and

ciently wide in fact, to provide for only su proper covering of the shell edges 26 and proper'adhesion to outer surfaces of the box end wall. Figs. 8 and 9 also illustrate'an arrangement in which the corner laps 23 are relatively'short so that their inner ends do not approximately meet, but aria in fact, 1 'widely separated in the completed box part,

as shown in Fig. 9.

In some'cases the'end end wings may be diiferently arranged or proportioned. For instance, in Fig. 10 these edges 40 are cut diagonally. When such a blank is .folded into box form, as shown in Fi 12,-the shell edges 40 while fully concea ed by the cover paperproduce an ap-. 'preciable irregularity or shoulder onthe edges of the shell v exterior surface of the box end "and in this way produce an appearance resembling that of one typical form of loose-wrapped box. Insome cases the cover material adjacent to, the diagonal shell edge 40, for instance, at

45, Fig. 11, may be cut approximately parallel to the shell edge, that is on a diagonal line, leaving, however, a marginal portion .46 of the cover material, sufiicient to overlap and cover the shell edge in the completed box, Fig. 13, and also of sufficient Width to properly adhere tothe outer sur-- face of'the adjacent corner lap. This arrangement'produces a box still more closely resembling a ty ical loose-wrapped box. o' By thedescn ed methods and principles of construction all portions,including the edges of the shell end wings, are fully covered and concealedby overlying portions. of the cover material and the box part corre sponds to the highest requirements of the folding mechanism, with adhesive applied where necessary, to make the completed box parts; or, of course, the folding and securing of the blanks into box formmay be done by hand operations where machines are not available.

As sufliciently explained in my prior patents and pending'applications, the formation of the central openings w in the shell web is in one respect required only for boxes of certain dimensions. Where the dimensions vary so that the end wings and esspecially the shell portions of the endwings are only as long as the corner laps, the formation of these openings w may be omitted; and in that case the shell end wing and corner la formations will be sufficiently duced y forming the longitudinal openings 6. The severing cuts along the lines 15 will then sever the corner laps and the shell end wings at the same time. On account ofother dimensional variations, the length of the openings w may also be varied'as desired.

The broader aspects of the production of the cover margins or flaps k alongside the longitudinal end wing edges 26, as herein disclosed, are claimed in the present application; but the production of such cover margins or flaps in certain other aspects or more limited aspects, and different variation s of the present method and structure,

are disclosed and claimed in my companion applications Ser. No.,612,170, filed January 12, 1923, and Ser. No. 612,171, filed-January 12, .1923. i What I claim is g V 1.
