3 Claims. Cl. 229-44 This invention relates to a folded cardboard carton for the reception of cigarettes or similar articles and ,with the major elements of the carton being formed from a single blank.

The invention contemplates a folded cardboard carton formed from a blank whereby an enclosing receptacle is formed for the conventional number of cigarettes and with the carton being provided with an encompassing band or slide with integral portions that are scored and bent in a manner that constitutes a foldable closure to completely overlie the ends of the cigarettes when the band is shifted upwardly and with the several sections being outfolding when the band is shifted downwardly to completely uncover the cigarettes.

The invention contemplates a carton as above recited that is also cut away upon opposite sides to expose a considerable length of the cigarettes when the slide is in the lower position to facilitate the removal of the cigarettes from the carton.

The invention further contemplates a carton having the above named characteristics wherein the cut away side portions are fully closed by one of the integral sections and with means being provided to prevent the closing means from shifting inwardly of the carton when the slide is shifted upwardly to fold the closure members over the tops of the cigarettes.

The invention further contemplates a cart-on having the above noted characteristics wherein stop means has been provided to limit the upward sliding movement of the band to the point where the carton is completely closed.

Novel features of construction and operation of the device will be more clearly apparent during the course of the following description, reference being had to the accompanying drawings wherein has been illustrated the preferred forms of the device and wherein like characters of reference are employed to denote like parts throughout the several figures.

Referring particularly to Figure 1, there has been illustrated a cardboard blank illustrated as a whole by the numeral 5. The blank includes carton forming sections that comprises side walls 6, a bottom 7 and infolding flaps 8 together with the tabs 9. The blank is scored at 10, 11 and. 12 whereby to facilitate the folding in of the flaps 8 and 9 with respect to the side walls 6 and bottom 7 to form a generally rectangular carton 13, see particularly Figure 3. It will be apparent, that the flaps in their folded assembled position will be cemented together, while the flaps 9 will be cemented to the bottom wall 7. The side walls 6 of the carton have been cut, as at 14 and scored as at 15 to form a generally V-shaped tongue portion 16 that is bendable along the line 15 in a manner to be presently described. The cut 14 forms a generally V-shaped opening 17 at the upper extremity of each side wall 6 and whereby to expose a considerable portion of the upper ends of the cigarettes, as shown more clearly in Figure 5. The tongue 16 is also scored along the line 18 and a section of the blank 5 at opposite ends, illustrated at 19 is scored along the lines 20 and 21 to be foldable and to constitute an overlying cover for the upper ends of the cigarettes. The score lines 20 and 21 define strips 22 and 23 together with a strip 24 that is connected at a line of scoring 25 with a slide forming section 26. As will be apparent, the blank is identical at opposite ends. The section 26 corresponds in width to the outer width of the cartonlS. The section 26 carries wing portions 27 that are bendable along score lines 28 and with the wings 27 being folded upon the wings 27 of the opposite end of the blank and cemented together whereby to form a slide band 29.

As illustrated in Figure 3, the assembly of the carton 'will be entirely apparent, while the slide has been illustrated in the initial step of assembly, with the flaps 27 adapted to be overlapped and cemented to each other as before noted. The sections 26 are cut away at 30, forming an opening whereby to expose a portion of the carton that may be engaged by the fingers of the operator to assist in holding the carton while the slide is operated. It may be found however that this opening is not essential.

In assembling the device, the carton is first formed by bending the flaps 8 inwardly along their score lines 10. Then bending the flaps 9 inwardly so that they overlie the bottom 7 when the side walls are bent upwardly along their score lines 11. After the flaps have been cemented to the bottom 7 and the flaps 8 cemented with respect to each other, a carton has been formed having the dimensions corresponding generally to the dimensions of a conventional cigarette package and wherein to receive the usual 20 cigarettes. The sections 22 and 23 and the section 24 are then folded along their score lines 20, 21 and 25 and also along the 'score line 18 to take a rela tively accordion-like shape. The section 16 is bent outwardly from the cut 14, with the section 22 bent in a reverse direction while the sections 23 and 24 are each reversely bent along their score lines. The sections 22, 23 and 24 as before stated, constitute the closure means for the top of the carton and are infolding from opposite sides so that the closure at each side extends inwardly to overlie the end of the cigarettes and to terminate in substantial abutment along the center line of the carton. The sections 26 having been bent downwardly and the flaps 27 bent inwardly, with the side walls of the carton with the flaps 27 in overlapping relation and in such position they are cemented together. With the flaps 27 in fixed engagement with each other, the slide 29 may now be shifted in the vertical plane to cover and uncover the opening or" the carton. As the slide 29 is shifted downwardly, it pulls upon the strips 24, causing the strips 23 and 22 to swing upwardly and outwardly in an unfolding manner, as illustrated in Figure 9, and as the sliding is continued in a downward movement, the section 16 moves away from the opening 17 and in a completely lower position of the slide, the sections to will be angularly disposed outwardly from the sides of the carton to fully uncover the openings 17 and expose the cigarettes at each side for ready removal. i /hen the device is to be closed, the operator grasps the lower end of the carton 13 through the cut-out of the slide and then shifts the slide in an upward direction forcing the strips 24 and 23 upwardly, swinging the sections 16 into recessed and flush engagement with the opening l7 and a continued upward movement causes the strips 23 and 22 to hinge over the top of the carton to the point where the strips 22 and 23 are folded together in overljng parallel relation to each other and with the strip 24 ill f,- wise extending partially over and dow; vardly into t opening of the carton and whereby to slightly recess tx, covers into the carton.

Since the opening 1'7 is for the major width of the upper end of the carton, means are desirable to prevent the shifting inwardly of the tongues 16 beyond their normal closure position when relatively few cigarettes are left in the carton. The means to prevent the inner movement of the tongues 16 comprises strips 34 that are cemented to the inner sides of the side walls o. The strips 34 carry flaps 35 and the strips have been cut away at 36 to form a generally V-shaped opening that is slightly smaller than the opening 17 and whereby to extend over the marginal edges of the opening, thus forming an abutment flange across the bottom end along the sides of the opening 17, and forming a stop against which the tongues in abut when the slide is shifted to fully cover the carton. The flaps 35 are scored along the lines 31 so that they may be folded inwardly with the flaps 8 to be cemented upon the inner sides of the innermost flap 8, as shown clearly in Figure 3.

in Figure 10, there has been illustrated a slightly modified form of the invention wherein stop means has been provided to limit the sliding movement of the slide The construction of this form of dispenser is substantially identical to that illustrated in Figures l-9 inclusive. Since it would be possible for a person to force the slide upwardly and above its normal range of travel, there has been provided flexible stop strips 38, having one end cemerited at 39 to the outer side walls 6 of the carton intermediate tlteir widths. The strips 33 at the opposite ends are cemented to the web portions in and with the strips 38 being of such length as to permit the slide to be shifted upwardly for fully closing the upper end of the carton to the point illustrated in Figure 8 and, in this position, the strips 38 will pr vent further upward movement of the slide. It will be recognized, that the entire structure described will be formed of a suitable cardboard recognized for its ability to bend at frequent inter vals, such as the necessary opening and closing of a carton of the type for dispensing cigarettes. It is also contemplated that the carton shall be dimensioned to accommodate the recognized standard lengths of cigarettes and, while the device has been illustrated primarily as a cigarette dispensing carton, that the construction may readily be adapted to cartons conta' ng other articles of the type whereby their upper extremities shall be exposed upon opposite sides of the carton to facilitate their removal and the invention is in no sense restricted to the dispensing of cigarettes.

in Figures ll and 12, a further modified form of the invention has been disclosed. The structure is substantially identical to that previously described, embodying the carton forming walls 16, bottom '7, side flaps t5 and infolding flaps 9, all scored as before pointed out to faciliate their folding and interlocking engagement. In this form of the invention, the wall forming blanks s have been cut along the lines 4%, being an extension of the score lines it). Such cuts ll? provide closure flaps 41 that are scored at d2; to be bendable outwardly to exnos openings at opposite sides of the carton for the The fla"s 4d are formed integral with the e forming members 26 through the medium of flaps that constitutes the closure means for the top The flaps 43 and are bendable along 1 lines 45, 4-5 and 4"), all being folded in the same that previously described. in this form of the pening extending from the end walls 8 of the carten, shown clearly in Figure 12. in this form of the invention, when the slide 29 is shifted upwardly, the flaps 41 swing upwardly to abutting engagement with the edges of the end walls 8 of the carton, thus preventing the flaps irom moving i wardly against the sides of the cigor, in ons where the major numbers of cigarettes have been removed, the flaps 41 could conceivably collapse into the carton unless they were stopped in their swi. a movement, and in such case it would destroy the closing action of the flaps 3 and Since the end obviously are relatively flexible, they w be held against outward spreading as the slide 29 moves upwardly, since the slide 2'? will effectively engage and prevent the outward movement of the end walls and maintain their edges in the path of movement of the llaps 4 1. in this form of the invention, the entire width of the package is ex rosed at opposite sides of the carton and results in a structure having no separately installed strips, such as that illustrated in the first form of the invention.

It will be apparent from the foregoing that an extremely novel form of carton device has been provided, the structure is extremely simple, being stamped from a single blank and folded in a novel manner to constitute a fixed carton, and an encompassing slide device and flap means connected with the carton and the slide that jointly fold over and upon the tops of the cigarettes within the carton. Much thought has been given to cigarette packages having a definite closing cover and whereby to protect the cigarettes and prevent the spilling of tobacco in the pockets or purses of the users. The device as hererol "c employed having closure covers are relatively expensive to manufacture and fail to a high degree in functioning properly to permit the cover to swing to and from the closed position without the flexing of the upper ends of the carton. The device of this invention provides a very novel form of slide that is shiftable upon the outer side of the carton in a snug sliding action and whereby to additionally support the carton against distortion and quickly and easily opens the upper end of the carton to expose a substantial length of the cigarettes at oppo .e si es and with the exposed lengths of the cigarettes being such as to permit their individual Withdrawal with a minimum of elfort.

is to be understood that the invention is not limited to the precise construction shown, but that changes are contemplated as readily fall within the spirit or" the invention as shall be determined by the scope of the subjoined claims.
