3 Claims.

The Vpresent invention relates to special constructions oi polyliedral boxes or the like, and more particularly, but not necessarily, to cigar boxes which are preferably made entirely from laminated paper board. Preferably also, the invention relates to polyliedral boxes made of laminated paper board wherein there is a supercial lamination of thin, tough and strong material, permitting the board to be angularly bent, without breaking, when grooves or open cuts are made in the other, but thickly built up, laminations to a depth substantially down to that of the tough and strong surface lamination which is to become one substantially continuous surface of a box body, Laminated paper board suitable for this purpose cannot easily be cut with grooves unless the board is thinner than the wooden board generally used in cigar boxes, for example, and which has a thickness of approximately, one hundred and nity points. 1f the so cut and grooved paper board is thinner than the usual wooden board, then the outside dimensions of the box constructed entirely from such board will be less than the standard dimensions for any given brand of cigars, if the interior dimensions are to be the same as preferably required for such a brand of cigar. Furthermore, it is usually required by cigar manufacturers, for example, that vcertain walls at least, of a cigar box be thick enough for safely receiving a nail. Y

Partly in view of the above considerations, the present invention contemplates a box including a bottom wall or the like and upright walls, together with a substantial thickness of laminated paper board covering and intimately unitedV With the inner surface or at least one of the upright Walls, preferably ol a box the upright Walls of which are also composed of laminated paper board of the character herein above referred to.

A specific object of the present invention is to provide a box, which is constructed mainly of the angularly bendable laminated board herein referred to, with a lining in the form of an inner collar and composed of laminated material which is thick enough so that when secured or gummed to the upright walls of the box, the interior dimensions of the lined box and the exterior dimensions of such box will correspond respectively -to the interior and exterior dimensions required in a wooden cigar box, for example, for any given brand or size of cigar.

These being among the objects of the present invention, the same consists of certain features 'of construction and combinations of parts to be hereinafter described and then-claimed with reierence to the accompanying drawing, showing two embodiments of the invention, and wherein Fig. 1 is a perspective view of a pre-cut and formed blank for a cigar box, the laminations not being shown;

Fig. 2 is a perspective view of the collar before it is placed in a box body which has been set up from the blank shown in Fig. l;

Fig. 3 is a top view of the box body as set up, including an inner collar or lining;

Fig. 4 is a plan of a strip of paper or fibre board from which the collar is formed;

Fig. 5 is a broken top View of a box constructed as in Fig. 3, but more clearly showing certain 'laminated characteristics; 1 (l Fig. 6 is a transverse section of the box as shown in Fig. 5; f

Fig. '7 is a perspective view of a modified construction of box according to the present invention; and 5 Fig. 8 is an enlarged transversed section of Fig. 7. Y

Referring to Fig. l, a box blank 10 is seen, which is preferably made of laminated paper board, of such character that there is an outer surface or skin of tough and strong thin paper and a thick inner, laminated, layer of weaker and inferior paper so that laminated paper board is provided which is bendable at angles formed by bending the outer superficial lamination into angles. The drawings herein are of such scale that paper board 0f the character referred to cannot be specically illustrated to disclose the multitudinous laminations of which the board is composed, but such character of board is disclosed in the application of George C. Snyder, Serial No. 304,424. Such application also discloses a novel box blank and a novel box made from such board.

The blank 10 is formed with a panel 11 of oblong rectangular shape, longitudinal side panels 12, 13 and transverse end'panels 14 and 15. These panels are deined at their inner edges by grooves, formed by cutting substantially V-shaped longitudinal grooves 16 into the paper board and also substantially V-shaped transverse grooves 17 into the board, such grooves being .in the thicker, preferably inferior, material. These grooves may extend as far as the tough super- 105 ficial skin of the paper board or substantially thereto. The practical vextent of depth to which these grooves may be cut in suitable material is more or less limited, for if the inferior laminated material is too thick, this will make much slower 110 the operation of cutting and grooving, and make the same more or less undesirable. The blank so described may now be shaped into the form of a box body 11,12, l3,14,15, (Fig. 3) in a machine for setting up boxes, and corner stays 18 of thin paper, or the like, may be applied to the upright corners of the box body.

When the blank has been properly cut it will have not only substantially V-shaped, intersecting, grooves 16, 17, but the parallel end edges of the panels 12, 13, 14 and 15 will be beveled, inasmuch as here the side portions of one-half of the grooves which were originally out along these lines will be removed with the corner pieces which are cut out as waste from the blank. When the box body is set up, as shown in Fig. 3, it will have a bottom 11, sidewalls 12, 13 and end walls 14, 15, composed of the corresponding panels formed in the blank of Fig. 1. Furthermore, the beveled side portions of the grooves 16, 1.7 and the corresponding edges of the ends of the upright walls will be substantially in abutting angular relation to form miter joints. inasmuch as the invention has been disclosed preferably in connection with a cigarbox, the end walls 14, l5 will be somewhat higher than the walls 12, 13, as shown in Fig. 6.

Now referring to Fig. 4, a length of laminated paper board in the form of a strip 19 is disclosed, and the thickness of this strip is preferably less than the thickness of the laminated board from which the described box body is made. The laminated structure and material of the strip 19 is preferably the same as for the box body, Fig. 3, but thinner, although the relatively tough lamination of the strip 19 need not be as tough as the corresponding lamination of the box body. Again, the drawings prohibit illustration of the laminated structure of strip 19, but such laminated paper board is well known and many thousands of laminated paper board boxes of the type illustrated in Fig. 3, but without a collar, have been manufactured and sold; these have had a thickness of 125 points. The laminated strip 19 of paper board has its laminations of inferior and weaker material grooved or scored trans- Versely at 20, preferably without removing material, so as to provide a panel 21, a panel 22, a panel 23 and a panel 24, the panels 22, 24 being of less` length than the other panels. The panels 22 24 are furthermore provided with upward extensions` 25, as shown in Figs. 2 and 4.

The box body 11, 12, 13, 14, 15, of Fig. 3 being now ready to receive the strip 19, suitable glue or adhesive substance, such as silicate` .of soda, for example, is applied to the creased or scored surface of the strip 19, either before lor after the strip has been bent upon the lines 20 to form a collar. The strip is best rst formed as in Fig. 2 into a collar which should have outside dimensions corresponding wlth the inside dimensions of the formed box body of Fig. 3, and inside dimensions required for the particular box. If the .strip is first formed into a collar, it is now inserted into the box body and glued to the inner surfaces of the upright walls so that it constitutes an inner lining for the box body, as in Fig. 3, except that the bottom 11 of the body remains desirably of the original thickness. rIhe inner surfaces of the upright walls of the box body will then be continuously lined by panels 21, 22, 23 and 24 of the original strip 19 of paper board.

Preferably the breadth of the lining or collar corresponds exactly with the height of the upright walls or" the box body, and when the lining has been correctly glued to the inner surfaces of such walls, and the ends of the strip 19 brought around into abutting relation at 26 in an inner corner of the box body, a box of the required standard thickness for the wooden board of cigar boxes will be provided. When the lining is neatly in place the upward extensions 25 of panels 22, 24 will be pasted or glued to the corresponding upward extensions of the end Walls 14, 15 of the box body. Whether silicate of soda or some other gluing or pasting medium is employed for securing the collar or lining in place, that is for adhesively securing together all of the surfaces of inferior laminated material at the inside of the vertical walls of the box body and at the outside of the collar, it is to be noted that preferably a glue is used which is without smell and which has a very low bacterial count so as to be unobjectionable to the users of the boxes.

Referring to Figs. 5 and 6, a box is shown on such scale that while the laminations of the inferior material cannot well be disclosed, yet the laminations are shown so far as the tough and strong skins or sheets in contrast with the thicker layers of laminated inferior material are concerned. In these gures the relatively tough and strong, but very thin, sheet 10a of paper or the like extends over and outside of the relatively thick layer 10b of laminated paper of inferior and cheap quality. Figs. 5 and 6 also disclose the relatively tough, strong and thin sheet or lamination 19a of the collar or lining, and the relatively thicker layer 19h of laminated inferior paper material.

A desirable thin and tough paper for the surface laminations 10a and 19a is kraft paper, al-

though cheaper yet tough and strong substitutes may be employed, and the lamination 19a may be of any suitable surface finishing material instead of kraft paper and of inferior quality thereto, yet capable of being bent at angles without breaking. TheY relatively thick layers 10b and 195 may well be composed of chip paper. It will be seen that the thickness of the collar or lining 19a, 195 need not be, and preferably is not, as great as the thickness. of the box body proper, Fig. 3. The relatively thick layer 19h of inferior laminated paper board is nevertheless preferably thicker than the thickness of the outer surface lamination 10a of the box body.

From Fig. 5 itis perfectly clear that the diagonal or miter joints formed at the substantial meeting edges of the upright walls of the box body are concealed and hidden from View at the inside of the box, by the continuous lamination of the collar. Fig. 5 also makes it clear that the scoring or creasing at 20 of the inner lining or collar, comes between the relatively tough inner lamination of the lining and the joints referred to. Fig. 6 makes it clear that the lower edge of the collar hides the miter joints between the bottom of the box andthe upright Walls. Hence, the collar completely hides all possible defects in the miter joints.

1n practice it has been found that the. thickness of the paper board composing the boxl body, such as shown in Fig. 3, may be 100 points and the thickness of the paper board from which the inner collar or lining is made may be of 50 points, so as to correspond with the number of points of thickness of solid walls of wooden, boxes. The bottom 11 of the box, however, preferably retains its original thickness of 100 points. However, the box body and lining may be of the same thicknesses and the thickly built up laminations of the lining may be cut and grooved like the box body.

Referring to Figs. '7 and 8, there is disclosed a modification wherein some, but not all, of the upright walls of the box are shown as having an additional substantial thickness over and above the original thickness 0I" the box body, such as shown.

In these gures the box is provided with a bottom 27, side walls 28, 29 and end walls 30, 3l, all of laminated material. Here the end walls 30, 31 are not additionally thicker. Referring to Fig. '7, the inner surfaces of the longitudinal laminated side walls 28, 29 are provided with complete laminated linings 32, 33 to give them an extra thickness, sufcient to meet the requirements as to nailing the cover to the box and of hinging the same thereto. In Fig. 8 the lamination formed by the relatively tough sheet or inner surface material 34 of each o1" the extra layers 32, 33 is shown, as well as the relatively thicker layer 35 of inferior laminated material. Desirably, corner stays 36 are applied to the box either before or after the thick layer of lining material is applied.

Obviously after a cigar box, for example, has been made according to the present invention, the well known wrapper and labels, binding strips, etc. are applied to give the finishing touches to the box, but as these are so well known they are not illustrated.

So far as the present invention is concerned it is not to be considered as limited to definite materials, nor to making the bottom and the upright walls ofthe box body from a single blank, but the invention is only to be limited as defined in the appended claims.

What I claim as new is:

l. A laminated polyhedral box, the body o which includes a main body-portion composed of a relatively thick inner layer of laminated paper board of inferior material and a continuous supercial outer layer of relatively thin paper material capable of being bent to provide the outsidey angular edges of the box, the relatively thick layer being pre-cut within and for the length of the running angular edges of the box so as to provide cut surfaces which are in mutual abutting relation, with joints between, and an inner lining of laminated paperboard glued throughout to the inner surfaces of vertical walls of the body-portion so as to cover the joints inwardly of the running angular edges of the box and to thicken such vertical walls, the lining terminating at the upper edges of such walls of the body-portion, such thickened walls being of a thickness of approximately one hundred and fty points, the thickness of the lining being approximately one-half of the thickness of the main body portion, so as to provide vertical walls having the thickness of the walls of standard cigar boxes, and adapted to receive and secure nails.
