BOX AND METHOD OF MAKING- THE-SAME.

Specification of Letters Patent.

Patented Mar. '7, 1922.

, Application filed December 31, 1920. Serial No. 434,313.

To all whom it may concern:

. Be it known that I, HARRY BRIDGMAN SMITH, a citizen ofthe United States, and resident of Brooklyn, in the county of Kings and State of New York,'have invented certain new and useful Improvements in Boxes and Methods of. Making the Same, of which the following is a specification.

My invention relates to a box of novel and economical construction, and to a method of rapidly and economically making such boxes. I

In several prior applications I have disclosed boxes and methods of making them, in which a box blank assembly is first produced, either by bringing a shell blank and a cover blank together with adhesive between them and turning over marginal portions of the cover and securing them adhesively to margins of the shell blank, or by bringing together continuous strips or webs of shell and cover material with adhesive properly supplied between them, turning over the margins of the cover strip and securing them to the shell strip, and severing the combined strips to produce box blank assemblies, which are substantially identical with those produced by the blank? or .sepahave usually been devised so that all ex posed parts of the completed boxes are covered by the cover paper, including all the outward edges of the shell.

4 The presentbox structure and method resemble previous. structures and methods referred to in a general way, but for certain classes of boxes 1t 1s found to be unnecessary to provide such a highly finished ox-.

In previous continuous assembly methods of my invention, that is. methods in which continuous strips of shell and cover material are brought together as a preliminary to forming the complete box blank assemblies, it has usually been necessary to out out portions of the continuous assembly strip and alsoto sever portions of the strip Such methods and boxes,

to produce complete blanks of desired forms. My present method avoids the necessity for cutting out portions of the strip assembly and reduces the operation of forming assembly blanks from the continuous assembly strip practically to the operation of cutting off sections of suitable length. This simplification and economy in the-continuous assembly method may be obtained without regard to whether-the boxes to be made from the blanks so produced are completely covered or not, that is, whether all exposed partsof theshell are protected by portions of the cover paper or some of them are ex posed. I

The characteristics and advantages of the invention are further sufficiently explained in connection with a detail description of the accompanying drawing, which shows structures and sufficiently illustrates certain method steps embodying my invention; and after considering theseexemplifications persons skilled in the art will understand that many variations may be made within the principles of the invention, and I contemplate the employment of any structures, methods and method steps which are properly within the scope of the appended claims.

In the drawings:

Fig. 1 is a perspective view of a continuous blank assembly, illustrative also of certain steps in its production method.

Fig. 2 is a perspective view of a complete, severed, box blank assembly.

Fig. 3 is a reverse view of the same.

Fig. 4 shows the assembly with side wings folded up.

Fig. 5 shows the corner or end laps folded 6 shows the end wings folded up against the end laps.

Fig. 7 shows a complete box structure. According to the continuous assembly method, sufficiently illustrated in Fig. l, a continuous strip or web W of box shell material, usually card board of suitable thickness, is fed, most conveniently from a roll.

not shown. A continuous strip or web X ofcover material, usually relatively thinner paper of suitable quality and finish, is fed into contact with the shell strip, usually also from a roll, and one of the strips iscoated on one of the contacting faces with adhesive y. This may be applied to a surface of either strip, but most conveniently for certain reasons is preferably applied as here shown to the upper surface of the cover strip X, and this application of adhesive may be made by means of aroller 10 or any other suitable instrumentality.

Previous to assemblycontact of the strips the shell strip is usually perforated at regular intervals providing apertures w, usually rectangular, as shown. The cover strip is usually substantially wider than the shell strip so that as the initial assembly is formed adhesively coated margins 50 of the cover strip extend beyond the edges of the overlying cover sirip.-

At a suitable point in the progress of the shell strip, or in the progress of the assembled strips, the shell strip, or both the shell and cover strip, as the case may be, are desirably creased or scored to facilitate subsequent bending. In the present case the shell'strip is scored along the longitudinal lines 12 previous to assembly contact and the assembled strips are scored along the transverse lines 13 after assembly contact; or all of the scorings may be made after assembly contact, or all of the scorings may he made upon the shell strip only, beforer initial assembly.

As the respective strips advance contact they are suitably pressed together and at a suitable point in their advance suitable instrumentalities are applied to turn over thecover margins at and press them'in ad hesive contact with margins of the shell strip, as shown in the left hand portion of Fig. 1. At a convenient point in'its advance the web assembly is then cut transversely as at 15, this transverse. cut extending centrally through the shell apertures 10 and through the portions of the cover paper underlying these apertures and thus a complete box blank assembly A, Fig. 2 is produced, comprising a body portion 20, side wings 21, end wings 22 and corner or end laps 23, which are desirably disconnected from the adjacent end wings by slit ting the blank assembly along the lines 24, this slitting operation being performed either before the blank A is severed from.

the web assembly, or after, as may be convenient. The severing of the combined webs along the lines 15 also produces marginal portions 2 of the cover extending beyond the ends of the shell end wings 22, ad-

. hesively coated in the original application of adhesive to the cover strip. in addition separate method; that is, separate cover and shellblanks of the same forms may be provided and brought into flatwise contact with adhesive between them and the margins 50 of the cover blank folded over and secured upon marginal portions of the shell blank.

r'u lhe blank-assembly, produced in either way, is now shaped into complete box form,

' involving at a suitable point in the shaping process the application of adhesive to outer (lower) surfaces 25 of the assembly, these surfaces being c-o-extensive with the outer surfaces of the assembly end laps 23. Regardless of the exact time in the complete method at which the adhesive is applied to the surfaces 25, the side wings 21 with their" connected end fiaps 23 are folded up as shown in Fig. l; and the end laps 25 arethen folded in, as shown in Fig. 5, whereupon their inner edges mayexactlyor approximately meet, or these edges may be sep arated more or less, depending upon the dimensions of the blank, or the desired structural characteristicsof the completed box. The end wings 22 are now folded up against the adhesive outer surfacesof the end laps and pressed in engagement, as shown in Fig.

(3, and the upstanding margins 2 of the cover (4 into box form, the shell end wings 22 may.

be separated from the cover end wings 22, thus exposing-inner surfaces of these wings both covered with adhesive, and the end or corner laps 25 may then be turned in and placed between these adhesive surfaces and the formation of the box completed above described in which case the edges e of the shell end wings will be overlapped and covered by the covered corner surfaces of the blank adjacent to the intersection of the blank side wings and corner laps.

A. suitable plunger or former is usually placed within the box structure as it is shaped into box form, and other instrumentalities are used: but a showing of these devices is omitted for the sake oli clearness;

and all of the method steps mayevidently be performed without the use of any instrumentalities, except hand instruments of the simplest sort.
