H. L. GREVE CARTON March 2, 1937.

Filed Jan. 17, 1955 IIIJIIIIIIIIIIIIIIIVIII!II INVENTOR an L. Grl/e' Harm &/c 6% ATTORNEY3 Patented Mar. 2, 1937 UNITED STATES PATENT OFFICE CARTON Application January 1'7, 1935, Serial No. 2,229

Claims.

My invention relates to cartons of cardboard or fibre board and a principal object of my invention is to provide an economical box or carton erected from a flat blank and having improved reenforced and interlocked end wall portions to obtain more secure assembly and better packing at the ends of the box.

Another principal object is to provide a carton having a locking means associated therewith and portions integral with the carton for concealing the. locking means and rendering the locking means inaccessible so that it is necessary to mutilate or partially destroy the carton in order to open it or to gain access to the lock.

Myimproved carton, embodying the features of construction making possible the attainment of the latter object, has been found especially useful in packaging bottles and particularly bottles containing spirituous liquors. As is well known, manufacturers of whiskey, brandy, gin, etc., are at considerable pains to render the packages in which their products are sold difficult of emulation in order that spurious products cannot be foisted upon their customers and, to this end, distinguishing marks are blown in the bottle and labels calculated difficult to counterfeit have been designed with the object of guaranteeing the authenticity of the brands. Despite these precautions, however, a substantial percentage of this character of merchandise is spurious. Therefore, it is a further object of this invention to provide a bottle carton which will render imitation more difficult, if not impossible.

Other and further objects will appear from the following specification.

Referring to the drawing:

Figure 1 is a plan view of a blank which, when erected and assembled, embodies all the features of my improved carton.

Figure 2 is a plan view of the box or carton completely erected, assembled, and locked.

Figure 3 is a sectional view on a larger scale, taken on line 3-3 of Figure 2.

r Figure 4 is a sectional view taken on line 4-4 of Figure 3. v

The blank comprises a flat sheet of cardboard or fibre board shaped substantially as shown in Figure 1 and scored to facilitate relative folding of its several parts which include a bottom portion It), side walls ll-ll and inner end wall portions I 2--l2 and I3--l3, respectively, carried by the side walls. Cover portions I l-l4 adapted to partially overlap and interlock with each other 55 are also carried by the side walls and their integral interlocking means comprise the edge tabs l5-l5, as will be readily understood.

The inner end walls portions l2 and 13 are of a length corresponding to the inside width of r the box, each portion l2 having a slot l6 therein extending from the outer edge of the blank, and each portion i3 having a corresponding slot l'l extending from its inner edge, whereby the inner end Wall portions at each end of the box may be assembled together edgewise and interlocked, as 10 shown in Figure 4.

The inner end wall portions 13 are preferably assembled outwardly of the portions !2 and carry flaps 18-48 adapted to be folded inwardly, as shown in Figure 3, and serving to carry the metal lock 25, hereafter referred to. Integral with each end of the bottom portion I0 is an outer end wall l9 carrying a flap divided by a score line into relatively foldable portions 20 and 2t, respectively, the flap having a slot or 20 perforation 22 therethru adjacent the end wall I9 to receive one of the metal locking tongues 26 carried by the overlying ends of the cover portions M-M, whereby the tongue may be extended into engagement with the lock 25. The flap portions 20 may also be provided with tabs 29-20', respectively, adapted to engage over end edges of the flaps l8, if desired.

The lock comprises a strip of sheet metal having a slotted flanged extension, the length of the slot corresponding to the width of the tapered metal tongue 26, and the tongue 26 has angular teeth 2625' struck up from its side edges to engage the lock adjacent the margins of its slotted area. Both the locks and the tongues are provided with a transverse score to facilitate bending. This locking means is more particularly taught in my co-filed application Serial No. 2,228. Other locking means may be employed in place of the

parts

25 and 26 if desired, such as the device disclosed in U. S. Patent No. 1,487,363 to Rothermund.

To assemble the carton, the sides and inner end wall portions are erected and the portions l2 and I3 are folded into laminated relation and interlocked. The bottle or other package content may then be placed in the box and the flaps l8 folded inwardly and the tabs 20 are engaged I over the adjacent end edges of the flaps IS. The flap portions 2| are then wrapped under the flaps l8 and pressed down against the package content.

To complete the assembly, the tongues 26 are bent inwardly at right angles, the cover portions l4 interlocked and the tongues inserted thru the 351 ner wall, a lock carried by the outer of said layers,

slots 22 into engagement with the locks 25 which lie between the inner and outer end walls.

Referring to Figure 4, it will be noted that the flap 2|, by reason of the resilience of the box material, bears against the bottle packaged in the carton and serves to cushion and nest the contents; also that the locks 25 and the interlocking portions of the tongues 26 are completely covered and obscured by the outer end walls Where they are inaccessible and cannot easily be tampered with. Therefore, to open the carton it is necessary to mutilate or partially destroy it, either by tearing or cutting the box material or breaking the metal locking parts.

Having thus described my invention, I claim:

1. A box or carton of the character described comprising a, bottom portion, a cover portion, and walls extending between said portions, one of said walls comprising a plurality of layers, the outer of said layers extending inwardly under said cover portion, a lock located between said layers, and means carried by the cover and extending thru the inwardly extending part of said outer layer and between said layers for engagement with said lock.

2. A carton of the character described comprising a bottom portion, a cover portion, and walls extending between said portions, one of said walls comprising two laminated layers of inaterial, an inwardly extending flap carried at the top of the outer of said layers, an outer wall carried by the bottom portion and overlying said laminated layers, and a flap carried by said outer wall and surrounding the flap carried by the inand means carried by the cover portion extending through said outer wall flap for engagement with said lock.

3. In a carton of the character described having a bottom portion, a cover portion, and walls extending between said portions, a lock carried by one of said walls, an outer wall carried by the bottom portion and overlying said look, a flap carried by said outer wall and extending inwardly under said cover portion, and means carried by the cover extending through said flap and between said outer and inner walls for engagement with said lock.

4. A carton of the character described having a bottom portion, a cover portion, side walls and end walls extending between said portions, said end walls comprising a double layer of material, one layer carried by a side wall and the other layer carried by the bottom portion, and a flap carried by each of said layers, said flaps extending inwardly in laminated relation at the top of the carton under said cover, the outer of said flaps being longer than the inner flaps and wrapped around the inner flap.

5. A carton of the character described comprising a bottom portion, a cover portion, and walls extending between said portions, an inwardly extending flap carried by one of said walls, an outer wall carried by the bottom portion and overlying said wall, and a flap carried by said outer wall overlying said flap, and extending around the free end thereof to provide integral means for securing said flaps together.
