ATTORNEYS United States Patent CARTON Application April 16, 1956, Serial No. 578,323

Claims. (Cl. 22944) This invention relates to a carton, particularly to a carton having a reclosable lid.

The carton provided by this invention is intended primarily for use in packaging cigarettes and similar rodlike articles, although this carton could be readily adapted to the packagingof other materials. Particularly, the present invention relates to a carton blank which may be readily adapted to the folding operations of the AMP 3-79 Standard Cigarette Packer such as generally shown in United States Patent 1,926,192. In this regard, reference is made to the copending applicationof William A. Ringler, Serial No. 542,368, filed October 24, 1955, in which application the advantages of a carton blank adaptable to the AMP 3-79 machine are set forth.

The present invention relates to such a carton blank and to certain features of the blank which provide for interlocking or nesting of a plurality of such blanks in their flat form, as cut from a sheet of material, with a minimum of space between adjacent such blanks. Such nesting of the blanks provides for the maximum utilization of material when cutting the blanks from a sheet of paperboard material or the like, with resultant economy of manufacture.

Accordingly, the primary object of this invention is to provide a blank for forming a carton having a reclosable lid and including recessed portions for receiving parts of identical such blanks in interfitting relation, and thus to provide for close inter-fitting or nesting of the blanks when cutting the blanks from a sheet of paper board material or the like.

A further object of the invention is to provide such a carton. blank which is adaptable to the folding operations of high speed packaging machines now in general use.

An additional object is to provide such a carton blank which is economical to manufacture, yet which provides a carton having a neat outward appearance'and of stiff and sturdy construction to afford adequate protection for the contents packaged therein.

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

2,824,684 Patented Feb. 25, 1958 Referring to the drawings, which illustrate a preferred embodiment of the present invention, a blank according to the invention is shown in Fig. l as including a rear panel 10 at one end thereof having an outer side panel 12 hinged to one side of panel 10 along a score line 13. An outer front panel 15 is connected to the opposite 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 glue flap 20 is hinged at 21 to the other edge of panel 18 for adherence to 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 a carton. I

The outer panels, arranged in longitudinal alignment,

and which constitute the main portion or outer member the completed carton. A slit, preferably continuous, is

provided through panels 12, 15 and 1S and includes a central portion 30 extending longitudinally 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 and 18, toward but spaced below the upper edges of these outer side panels. A score line 33 extends transversely of rear panel 10, spaced below the upper edge thereof and spaced somewhat above the end of slit 32 in the adjacent side panel 12, and a score line 33 is also provided across glue flap 20, intersecting fold line 21 above 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.

Short vertically extending slits 34 connect the adjacent ends of score line 33 and slit 32 and score line 33 and slit 31, extending along thefold lines 13 and 21, respectively. Thus, these slits and the associated score lines divide the main portion of the blank into upper and lower sections, with the parts of the blank between the upper edge thereof and the slits and score lines providing front, side, rear and top walls of a reclosable lid which is hinged to the main body of the carton along line 33. The portions of the blank below the slits and score line are foldable to provide an open top box to which the reclosable lid is integrally hinged, and the portion of the rear panel 10 below score line 33 and between the slits 34 provides a flexible connection between the lid and the remainder of the carton, distributing the flexing and bending stresses due to opening and closing movements of the lid over a wider area, and thus minimizing the tendency of the lid hinge connection to break or tear in use.

At the bottom of rear panel 10 a bottom flap 35 is articulated, and is provided with a cut-away or relieved,

portion 35 at its free end. A second bottom flap 36 is articulated to the lower edge of panel 15, and partial bottom side flaps 37 and 38 are hinged to a major portion of the lower edges of side panels 12 and 18. An inner member including an inner front panel 40 and inner side panels 42 and 43 extends from the lower edge of the outer member. A continuous slit 44 separates flap 36 from all adjacent portions of the inner member, and the inner side panels are integrally hingedly connected to the outer member along fold lines 45 and 46 separating outer and inner side panels 12 and 42, and outer and inner side panels 18 and 43, respectively. Slits 47 and 48 separate the inner side panels from the bottom side flaps 37 and 38, and thus the entire inner member is foldable as aunit into superposition upon the outer member. The. he ight of the inner panels is such that panels and'te'rmin'ate slightly beneath the upper edges of these panels, as shown in Fig. 3. Portions of the fold lines separating inner front panel 40 from the inner side panels 42 are slit and offset 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 edge of inner front panel 40 is provided with a central cut-away portion 50 which affords an access opening in the completed carton.

Blanks in accordance with the invention are particularly adapted for arrangement in their flat form, as cut from a sheet of material, for interlocking or nesting with each other to minimize the amount of material wasted when cutting such blanks from a sheet of paperboard material or the like. Thus, the presentinvention provides for the maximum utilization of such material with resultant economy of manufacture. In order to provide for such interlocking or nesting the free sides of the inner side panels are formed with recesses 55 therein defining full width portions at the ends of the. inner panels including projecting parts 56 which arearranged to overlie the slits in the outer side panels in the folded form of the blank as shown in Fig. 3. Recesses 55 are complementary in dimension to projecting parts 56, and thus the recesses of one such blank will receive the projecting parts of another such blank laid out in inverted form beneath the first blank.

The interlocking or nesting arrangement is illustrated in Fig. 2, wherein one corner of a sheet 60 of paperboard material or the like is indicated by the dot-dash lines, and wherein a plurality of the blanks such as shown in Fig. 1 are arranged in the interlocking or nesting relation provided by the invention. It will be apparent upon inspection of Fig. 2 that the area of sheet material between adjacent blanks and not forming a part of any blank is slight in comparison of the overall area of the sheet. The interlocking arrangement thus provides for maximum utilization of the sheet material and thereby reduces the overall cost of manufacture of the blanks.

The carton blank of this invention is particularly adapted to the folding operations of the AMP 3-79 cigarette packing machines, such as set forth in the above identified copending application of William A. Ringler. With the inner member panels superimposed onto corresponding outer panels, as shown in Fig. 3, the blank may be folded into open tubular form about a rectangular tubular mandrel such as embodied in these machines, with a series of only four folds providing for complete tubing of the blank. Thus, referring to Fig. 4, the inner and outer side panels are folded about the sides of the mandrel, substantially at right angles to the front panels as shown in Fig. 4. A suitable adhesive is applied to the outer surface of glue flap 20, as indicated by the stippled portions in Fig. 4, and the glue flap is folded over as indicated by arrow 65 substantially at right angles to the adjacent side panels. The rear panel 10 is then folded along line 13, as indicated by arrow 66, to complete the tubing of the blank and provide for adherence of the free edge of the rear panel to the glue flap.

The top and bottom walls of the carton are formed in the usual manner, as described in the above identified copending application, to complete the assembly of the carton as shown in Fig. 5. With the lid open, as illustrated in Figs. 6 and 7, access to the contents is readily provided by the recess 50, and tabs 48 extend against the side walls of the lid to provide a frictional resistance to opening and closing movements thereof, tending to retain the lid in its closed position. Furthermore, the upper edges of front panel 40, particularly at the connections thereof with the upper edge of inner side panels 42 and 43 which form the upper front corners of the open top box portion of the carton, extend within the lid substantially to the top wall thereof and intersect the path of movement of the front wall of the lid. This arrangement of the parts requires that a certain amount of intentional pressure be exerted to swing the lid between its open and closed positions.

The carton blanks provided by the invention are also adaptable to use in a number of other high speed packaging machines. For example, the blanks of Fig. 3 can be assembled into flat folded tubular form for shipping and/or storage, and'in this form the blanks are adaptable to use in highspeed packaging machines which erect the fiat tubed blank, form the bottom wall'thereon, fill the erected carton, and finally form the'top Wall from the top flaps thereof. The fiat tubing of the blanks can be performed by high speed glueand folding machines which apply a suitable adhesive to 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 carton provided by this invention is preferably formed from relatively stiff paperboard stock and thus is resistant to crushing and affords ample protection to cigarettes during normal handling. Such protection is necessary in present day packaging operations with cigarettes, since many brands of cigarettes incorporate filters or other special tips which tend to break away from the remainder of the cigarette when the package is crushed or bent. Also, since the outer panels of the cartons are continuous across the slits 30, 31 and 32 there is no problem of registry between the adjacent portions of the carton body and the lid when it is desired to print upon the outer surface of the blanks.

The present invention therefore 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. Thus, this invention provides a carton which is readily adaptable to present day packaging operations.
