9 Claims. (o1. 229-) The present invention has relation to the manufacture of boxes of a particular type and while the invention is especially applicable in the manufacture of cigar boxes, the invention may also be applied with advantage to boxes used for packing and displaying other kinds of merchandisc.

The invention will be hereinafter described in connection with the manufacture of cigar boxes or other cases where certain special requirements have to be filled. Heretofore cigar boxes have generally been made of wood because the first requirement in packing of cigars is a rigid box so that the cigars may be safely shipped or handled without danger of being crushed. Another requirement is the distinctive appearance of the box because since the trade has become accustomed to the use of wooden cigar boxes for a. great many years it might be difficult to substitute paper boxes unless the box made of paper has the features of a wooden box. Heretofore cigar boxes have been made partly of wood and partly of paper board and various methods of manufacture have been employed. Such boxes have apparently not satisfied the demand for the special box required for cigars and it is the main purpose of the present invention to produce a box made entirely of paper board which will meet all the requirements for a practical cigar box. In common practice folding and set up boxes of all kinds are made entirely of paper board and said board is of different gauge from the very light weight to comparatively heavy board. Furthermore, in the manufacture of boxes made of paper board it is customary to score or crease the board where it is to be bent or in some instances, the board is partly cut at the bending point so as to permit of the bending without breaking the board. It is proposed, according to this present invention, to use extra heavy board ordinarily incapable of being bent without breaking and the purpose of using this heavy board is to meet one of the requirements for cigar boxes, viz, a rigid box.

In carrying out the invention'the paper board used may be of ordinary stock but to get the full advantage of the invention, the stock is composed of laminated sheets of which the outer or top lamina or lamina: is composed of comparatively tough material and the inside laminae are of a common stock kind which is more or less deficient of fiber. Other kinds of board may be employed provided the outer surface has sufficient tensile strength to permit it to stand the bending operation without breaking.

In the manufacture of the improved box. the board is blanked out into sheets from which the box is ultimately made up. Various alternative methods of carrying out the invention will be hereinafter described and in each example or embodiment of the invention the blank is divided into a number of sections by a cut score or groove at the point where said blank is folded to form the walls of the box body. These grooves or scores are cut partly through the stock, that is, up to the outer lamina or covering of the top surface of the board and the uncut portion acts as a hinge on which the various sections are bent to form the walls of the box body or frame forming the base for the box. The cut scores may beon either side of the board depending whether or not the sections fold inwardly or outwardly and when the sections fold inwardly, said out scores are preferably V-shaped so that the edges will come together with a mitre fit but where the sections fold outwardly the cut is straight throughthe board up to the binding or surface lamina. When the blank is folded to form said box body or frame the corners of said body are held together and reinforced by strips or stays which are preferably secured by adhesive means. The next operation is to add a covering shell preferably composed of foldable paper board which may be of superior quality. Said board may be printed or otherwise decorated to represent different kinds of wood, for example. This covering may be on the outside of the box only, but if desired, a similar lining may be applied to cover the inside of the box.

The box body built up, as above described, is then ready for the final finish and this usually is the application of binding of the usual strip or ,Webbing commonly employed in the manufacture' of cigar boxes. It will be understood that the lining may be applied to the box body not only for decoration purposes but as a strengthening means. An outer wrapper is generally employed to cover the complete outside surfaceof the box and which wrapper may be suitably printed and decorated.

The improved method of manufacturing the box briefly outlined above and more fully described hereinafter has the advantage that boxes made by this method are produced with greater facility, more economically and the box is strengthened to the maximum degree obtainable with the material employed and the appearance of the box is greatly improved.

The several embodiments of the invention will be hereinafter described with reference to the accompanying drawing, wherein- Figure l is a perspective view showing the invention as applied to a cigar box;

Figure 2 is a detail view of the frame member of the box body; and

Figure 3 is a perspective view showing a separate member forming the shell or covering for the box body. 7

Referring to the embodiment illustrated in said drawing the box body 1 is of a rectangular shape having a front wall 2, back wall 3 and end walls 45. Following the usual practice, in making a cigar box, the end walls 45 are slightly higher than the front and back walls so as to provide a recess 6 to receive the cover 7 when in a closed position, so that the top surface of the cover will lie flush with the upper edges of the side walls 4-5. The purpose of this fitting of the cover is to ensure a tight closure and to stiffen the box structure. The box body is composed of several members or parts of which the main member is the frame 8 composed of heavy, non bendable paper board. This frame may be in the form of a strip which is divided into sections by cut score lines 9, said sections being numbered 2', 3', 4', 5' forming respectively the front, back and end walls of the structure. The board preferably employed is of such a thickness and weight that the box produced therewith is equally as rigid as the boxes heretofore made of wooden strips or panels. The paper board employed may be composed of laminated sheets or the board may have a pressed paper pulp filler which is covered by a paper sheet 10 on one side and sheet 11 on the other side. The covering sheet 10 should be of comparatively tough material so as to hold the frame together, in its set up position for it will be understood that the sections, when folded, are hinged on the uncut surface sheet 10. The cut 9, it will be understood, in one form is cut through the outer covering sheet 11, through the filler but the inner sheet 10 is not out. It will be noted when so prepared the folded frame presents neat and unbroken corners on the inner side of the box but on the outside, in folding, angular grooves are left but which latter are covered in a manner hereinafter set forth.

As hereinbefore stated, the frame 8 of the box body may be composed a continuous strip and when the frame is formed, the two ends of the strip are brought together with a butt joint, as shown at 12, and a stay piece 13 is adhesively secured preferably on the outside to hold the ends together. In order to keep the front and side walls perfectly parallel to each other to provide a squared box structure, the end wall section 5' is of a greater length than the opposite section 4 so that the butt joint referred to may be employed. v

Another component part of the box body is a shell 14 as shown in Figure 3 of the drawing. This shell 14 is composed of box board of the usual kind employed for making folding boxes.

This board is cut out in the form of a blank having sections 2" 3", 4", 5". which form reinforcements or coverings respectively for the back, front and end walls of thestructure. The shell 14 has the central section 15 which constitutes the'bottom of the box when said shell is located in its operative position with relation to the open frame 8. When this shellis locatedin place the corners are united and retentively heldby corner stays in the usual manner followed with the manufacture of set up boxes.

The'body of the box having been formed by the assembling of the frame.8 and shell 14, the

box body is then ready to be finished in the customary Way by covering the same with a printed or decorated wrapper 16. The outer shell 14 may, however, be printed or decorated directly so as to represent cedar wood, for example, and the corners and edges of the box body may be covered by a binding web in the usual manner.

It will be obvious with the embodiments of the invention hereinbefore described, that the hinges or cut scores 9 of the frame 8 may be inside of the box structure and in which case the cuts would be in the form of V-shaped grooves so as to produce a mitre joint. .With this modification the reinforcing shell may be placed inside of the set up frame 8 for it will be understood that when the frame 8 is folded as in this example, the outer corners of the structure are not broken.

Various modifications may be made in carrying out the constructional details of the invention or in the application of the same other than hereinbefore described and it is therefore to be understood any modification coming fairly within the terms of the appended claims shall be covered thereby.
