CARTONS FOR ELONGATED ARTICLES Filed June 28, 1956 2 Sheets-Sheet 2 INVENTOI? John E.Tulberr ATTORNEY United States Patent 3,099,382 CARTONS FOR ELONGATED ARTICLES John E. Talbert, New Canaan, CDIHL, assignor to American Machine and Foundry Company, a corporation of New Jersey Filed June 28, 1956, Ser. No. 594,630 7 Claims. (Cl. 229--44) This invention relates to a carton, and particularly to a carton having a reclosable lid.

The carton provided by this invention is intended primarily for use in packaging cigarettes and similar rod-like articles, although this carton could be readily adapted to the packaging of other materials. There are in use many cigarette packing machines manufactured by the American Machine and Foundry Company of New York, and such machines are generally shown in United States Patent 1,926,192. These machines are at present used to provide the well known cigarette package comprising an (inner foil wrap and an outer paper pouch which is in turn covered with a cellophane wrapper.

Cigarette cartons having integral hinged lids heretofore proposed have met with little commercial success largely because they are not, generally speaking adaptable to the folding operations of the American Machine and Foundry Company packing machine, and because the conversion of these machines for use with such cartons has either not been possible or has been prohibitive from the standpoint of cost. In spite of the fact that a reclosable lid type of carton provides many advantages from the standpoint of neatness of appearance and resistance to crushing during handling and use, the packaging industry, particularly with regard to cigarette packaging, has largely continued the use of the present well known cigarette package and has not employed the paperboard carton type of package.

It is therefore a primary object of this invention to provide a blank for forming a carton having a reclosable lid which is adapted to the high speed folding and packaging operations of folding and packaging machines now in general use.

Another object of this invention is to provide such a blank which is simple and economical to manufacture, yet which provides a carton having a neat and sturdy appearance.

A further object of the invention is to provide in such a carton an inner member comprised of three panels which include inner side panels hinged to the lower edges of the main or outer side wall panels of the carton for lateral folding with respect to the lower edge of the outer side panels to a position wherein the inner member is superimposed upon the main portion of the carton blank, providing a member for supporting and presenting the contents when the carton top is open.

An additional object of the invention is to provide such a carton wherein the inner front panel only may be adhered to the outer member, leaving the inner side panels free to slide relative to the outer member during the folding operations.

Another object of this invention is to provide a package for cigarettes and like articles wherein the articles are completely covered by a sheet of foil, and wherein the foil enclosed articles are packaged in a paperboard carton having a reclosable lid, and to provide a blank of paperboard material which may be folded by high speed packaging machines to provide such a package.

A further object of this invention is to provide a method of forming a carton having a reclosable lid by providing a blank including inner and outer members, and folding the inner member into superposition upon the outer member, and then folding the blank about the mandrel into open tubular form and securing the blank in this form.

Another object of this invention is to provide an inner carton member which is an integral part of the outer carton blank.

Still another object of this invention is to provide an outer carton folded together with an inner foil liner so that the foil is locked to the outer carton to prevent the pull out of the liner when the package is opened.

Other objects and advantages of the invention will be apparent from the following description, the accompanying drawing and the appended claims.

' a rear panel 10 at one end thereof having an outer side panel 12 hinged to one side of panel 10 along the score line 13. An outer front panel 15 is connected to the op posite side of panel 12 along line 16 and the other outer side panel 18 is attached to the opposite side of panel 15 along line 19. A vgl-ue flap 20 is hinged at 21 to the other edge of panel 18 for connection with rear panel 10 to retain the blank in tubular form. A series of top flaps 22 23, 24 and 25 are independently hinged to the upper edges of

panels

10, 12, 15 and 18, respectively, for forming a top wall on the carton.

The outer panels, which constitute the main portion of the blank in FIG. 1, are provided with slitted and scored portions for the fonm-ation of a reclosable lid on the completed carton. A continuous slit is provided through

panels

12, 15 and 18 including a central portion 30 extending horizontally across front panel 15 parallel to and spaced below the upper edge thereof, and slanted or bias-cut

portions

31 and 32 extending from opposite ends of slit portion 30 upwardly at an angle across panels 12 land 18, toward but spaced below the upper edges of these outer side panels. A score line 33 extends transversely of rear panel 10, spaced from the upper edge thereof and intersecting the end of slit portion 32, and a score line 33' is also provided across glue flap 20, intersecting the end of slit portion 31 and located on the glue flap to register with score line 33 when the blank is folded into tubular form. Thus, the continuous slit and the associated score lines 33 and 33' divide the main portion of the blank into upper and lower sections, with the sections of the blank between the upper edge thereof and the slit and score lines providing front, side, rear and top walls of a reclosable lid which is hinged tothe carton along line 33. The portions of the blank below the slit and score line are foldable to provide an open top box to which the reclosable lid is integrally hinged.

At the bottom of rear panel 10 a bottom flap 34 is articulated. A second bottom flap 36 is articulated to the rear edge of panel 15, and surrounding this flap is a series of inner panels providing an inner member for the completed carton. Thus, the inner member includes an inner front panel 46 and

inner side panels

42 and 43. A continuous slit 4-4 separates flap 36 from all adjacent portions of the inner member, and the inner member is in tegrally hingedly connected to the outer member along

score lines

45 and 46 separating outer and

inner side panels

12 and 42, and outer and

inner side panels

18 and 43, respectively. The advantage of this structural method is that it provides a neater package bottom than generally results from connecting the inner member to the back panel. Thus, the entire inner member is foldable as a unit along

lines

45 and 46 into superposition upon the outer member, and the height of the inner panels is such that they extend across

slit portions

30, 31 and 32 and terminate slightly beneath the upper edge of the

outer panels

12, 15 and 18. A portion of the fold lines separating inner front panel 40 from the

inner side panels

42 and 43 is slit and oifset somewhat adjacent the outer edge of the blank to provide tabs 48' extending outwardly from opposite sides of panel 40. These tabs serve to retain the lid of the carton in its normally closed position as will presently be described. Also, the free upper edge of inner front panel 40 is provided with a central cutaway portion 50 which affords an access opening in the completed carton.

In order to adapt the carton of the present invention to high speed packaging operations, it is desirable to fold the inner member onto the outer member, as shown in FIG. 2, by the use of automatic folding equipment either separate from or in combination with a high speed packaging machine. Thus, it is desirable that flap 36 remain coplanar with panel 15 for further folding operations.

The blanks, either in flat condition or in the flat folded assembled condition, are readily adaptable to feeding from a magazine of a packaging machine. In the former instance a preliminary told is made in the blank feeding mechanism of the packaging machine to superimpose the inner blank member upon the outer member. Or, the blanks may be pre-folded in a high speed machine and then placed in the packaging machine magazine, as in the latter instance. In either event only four folds are required to tube the blank, that is, to assemble it in open tubular form. The upper portions of the inner member overlie the continuous slit through

panels

12', 15 and 18, and the free upper edges of these panels provide continuations of the front and side panels of the open top box referred to above ivhich extend into the closable lid of the car-ton.

The sequence of steps shown in FIGS. 11-12, 3, 4 and illustrates the formation of a carton from the blanks shown in FIGS. 2 and 9. These steps may be performed by high speed packaging machines, for example of the type shown in :above mentioned United States Patent 1,926,192. As previously explained, the blanks are fed from a magazine. As the inner member of the blank is folded onto the outer member, bottom fiap 36 remain-s coplanar with the outer front panel 15. FIG. 11 shows a hollow mandrel 65 of the type shown in the above men-j tioned patent, for example, in FIGS. 33-37 thereof. A sheet of foil 70, having a perforation 72 extending across one of its ends, is wrapped about the mandrel in the usual manner. Such a foil sheet is also shown in FIG. 7 of this application.

The carton blank, with the inner and outer members folded together, is positioned against the mandrel with the inner front panel 40 abutting one of the larger flat faces thereof and overlying foil sheet 70, preferably on the side of the foil, opposite from the overlapped edges thereof. The side panels of the blank are then folded around the smaller sides of the mandrel, as shown in FIG. 12. Suitable adhesive is applied to the outer face of glue flap 2i), and the glue flap is then folded along line 21 onto the other large side of the mandrel as indicated by arrow 73, and finally rear panel 10 is folded in the direction of arrow 74 into contact with glue flap 20 for adherence thereto. Thus, the blank is folded into open tubular form about the mandrel.

The top wall of the carton is next formed by folding

flaps

23 and 25 inwardly over the foil, as shown in FIG. 3. Flap 22 is then folded across the end of the carton in the direction of arrow 75, and finally flap 24- is folded over in the direction of arrow 76 and adhered to the outer surface of flap 22 by a suitable adhesive (not shown). With the top Wall of the carton formed, the articles to be packaged, for example cigarettes indicated generally at 8i? in FIG. 4, are pushed into the interior of the hollow mandrel by a plunger (not shown) and the stroke of the plunger is extended until the cigarettes abut the now closed top wall of the carton and push the entire assembly of carton, foil and cigarettes off the hollow mandrel.

The sides of the foil sheet, which extend below the lower edges of

side Walls

12 and 18, are next tucked inwardly over the open bottom of the carton, the bottom fiaps 96 are folded in, and the flap 34 is folded over as shown in FIG. 4 to fold the part of the foil overlying that flap across the bottom of the carton. Finally, flap 36 is folded over along fold line 56 across the bottom of the carton, carrying with it the remaining portion of the foil.

Flaps

36 and 34 are secured together by a suitable adhesive (not shown) to complete the forming of the carton. Due to the provision of cut away portion 35' in flap 34 when that flap is folded downwardly, it contacts only portions of the foil sheet which have been tucked in from the sides, and when flap 36 is folded over the portion of the foil folded in by this movement contacts the foil already folded over and none of the carton material comes into contact with the contents packaged within the carton.

The completed carton is shown in FIG. 6 with the lid in its closed position, and in FIG. 7 the carton is shown with the lid swung to its open position. It will be noted that the cut away portion 50 provides an access opening in the upper frontal edge of the open top box portion of the carton. The height of panel 40 is such that the free upper edges thereof at the corner of the box intersect the are through which the front wall of the lid swings about hinge line 33, and thus a certain amount of force is required to slide the front wall of the lid over the upper edge of the box. In addition, tabs 48 engage the front corners of the lid and assist in retaining it in its normally closed position.

FIGS. 8-12 show a modified form of the invention. The bottom flaps 96 are omitted from the

side panels

12 and 18. Two extra parallel transverse folds are provided at the hinge position 45 in the

inner side panels

42 and 43 as shown in FIGS. 10 and ll. An integral corrugated connection is thus formed between inner and outer side panels. This expedient provides a pleated or corrugated tuck 46 at the bottom of the side panels of the finished box as shown in FIG. 12 and thereby automatically eliminates any gap which slightly irregular forming operations introduce between the bottom and side panels in the absence of the bottom side flaps 96. 1

So far, the present invention has been described in connection with cigarette packaging machines, but it is to be understood that the cartons provided by the invention are adaptable to use in any number of high speed packaging machines. Thus, for example, the blanks of FIGS. 2 or 9 can be assembled into flat folded tubular form for shipping and/or storage, and in this form the blanks are adaptable to use in high speed packaging machines which erect the fiat tubed blank, form the top wall thereon, fill the erected carton, and finally form the bottom wall from the bottom flaps thereof. This folding can be performed by high speed gluing and folding machines which apply a suitable adhesive to the glue flap 20, fold the glue flap and adjacent side panels over onto the front panels, and then fold the rear panel 10 onto the glue flap for adherence thereto.

The inner foil wrapper 7 0 is provided within the carton to enclose the cigarettes, as previously described, and this foil includes the weakened or perforated line 72 extending around its entire periphery, as shown in FIG. 7. The perforations 72 are preferably located to extend across the upper end of the package between the upper and lower ends of access opening 59. Thus, the upper section of the foil wrapper above perforation line 72 may be removed to provide access to the cigarettes. The reclosable lid for the carton provides easy access to the cigarettes at all times, yet keeps them enclosed and thus relatively fresh. Furthermore, the still? stock from which the carton component of the package is made is resistant to crushing and affords ample protection to the cigarettes during normal handling.

Thus, the present invention provides a carton having a reclosable lid which is simple and economical to manufacture and assemble, and which is particularly adaptable to use with high speed folding and packaging machines now in general use. The present invention provides a carton which is readily adaptable to present day packaging operations.

Also, since the outer front panels of the cartons are continuous across the slits 30, there is no problem of registry between adjacent portions of the box portions and the lid portions of the carton when it is desired to print upon the outer surface of the blanks.

While the method and the articles herein described constitute preferred embodiments of the invention, it is to be understood that the invention is not limited to this precise method and these forms of articles, and that changes may be made therein without departing from the scope of the invention which is defined in the appended claims.
