Morton KOLTZ ATTORNEY United States Patent 3,207,416 SIDE-HINGED CARTON AND BLANK FOR PRODUCING THE SAME Irving Morton Koltz, Montreal, Quebec, and Jack Benjamin Rozen, Chomedy, Quebec, Canada, assignors to Pop Design Consultants of Canada, Ltd, Quebec, Quebec, Canada Filed June 1, 1964, Ser. No. 371,264 7 Claims. (Cl. 22944) This invention relates generally to an improved carton having an integral, hinged lid.

In many instances, when packaging certain commodities, such as cigarettes, ice-cream, cake-mixes, pancake flour, etc., a carton with a hinged lid is desirable since the lid may be pivoted out of the way to permit ready access to the carton contents and pouring of powder-like materials is facilitated. Further, there is a demand for a carton which is substantially pilfer-proof, and which can be substantially sealed when closed so the remaining carton contents can be kept fresh.

Still further, it is desirable to have a carton which uses a minimum amount of paperboard material, which is readily assembled and erected, and which is highly versatile and satisfactory for the purpose intended.

A primary object of the present invention is to provide a carton produced from a one-piece blank which is cut and scored to produce a hinge-end carton having the desirable features mentioned above.

Another object of the present invention is to provide a carton of the character mentioned above, and produced from a one-piece blank, in which the lid of the carton is not only hingedly connected to the lower product-receiving portion of the carton, but which is also connected to an element limiting rearward pivotal action of the hinged lid and which affords a toggle-like snap-action to urge the lid toward either an open or closed position with respect to the product-receiving portion of the carton.

A further object of the present invention is to provide in a novel carton produced from a one-piece blank, means for detachably connecting the lid to the product-receiving portion of the carton, and in which detachable-connection means which must be severed or ruptured when opening the carton are provided to readily appraise one of the fact that the carton has been previously opened.

A still further object of the present invention is to provide in a carton of the character set forth, a simulated sleeve-like extension integral with the upper edge of the lower product-receiving portion of the carton, and in which the sleeve is disposed within the hinged lid to provide an effective and desirable seal to maintain the product being packaged in a relatively fresh, usable condition.

Other and more specific objects and the nature and advantages of hte invention will become apparent from a consideration of the following description, taken in conjunction with the drawings forming a part thereof, where- FIGURE 1 is a perspective view of the erected carton in a closed condition;

FIGURE 2 is an enlarged, perspective View of the upper portion of FIGURE 1, looking into the corner opposite that shown in FIGURE 1, and showing the lid in open condition;

FIGURE 8 is a plan view of a blank used to produce the carton construction illustrated in FIGURES 1-7;

FIGURE 9 is a fragmentary plan view of the top portion of the blank showing the initial folding step during assembly of the carton;

FIGURE 10 is a fragmentary plan view illustrating the second fold step in the assembly of the carton;

FIGURE 11 shows a third folding step after which the carton is assembled to form a rectangular tube; and

FIGURE 12 is a top plan view of the carton when erected as a rectangular tube from the conditions shown in FIGURE 11, and showing particularly the manner in which the toggle-panel engages on the upper edge of the simulated sleeve of the carton as the lid or top is pivoted toward an open or closing position.

Referring to the drawings in detail, and first referring to FIGURE 8, a one-piece planar blank is indicated generally at 10 and may comprise any suitable material for the purpose intended, for example, paperboard, plastic-coated board, plastic, etc. The blank 10 is substantially rectangular, and thus lends itself to production with a relatively small waste of material. Additionally, although the blank is illustrated and has the proportions of a carton useful for packaging cigarettes, pancake flour, etc., this disclosure is only by way of illustration and not limitation.

The blank 10 comprises a first end wall panel 12, a first side Wall panel 14, a second end wall panel 16, a second side wall panel 18, and a glue-flap panel 20. Adjacent panels 12-20 are respectively connected to each other on mutually parallel fold or score lines 22, 24, 26 and 28. The first end wall panel 12 includes a free side edge margin 30 and the glue-flap panel 20 has a free side edge margin 32. Panels 12-18 include a lower margin defined by a single transverse fold or score line 34. Hingedly connected in depending relationship to the panels 12-18 are lower rectangular closure flaps 36, 38, 40 and 42, respectively. Panels 36-42 are separated from each other by cut-lines 44, 46, and 48, respectively, colinear with fold-lines 22, 24 and 26.

The panels 12-18 include an upper margin defined by a transverse, linear fold-line 50 parallel to fold-line 34 and colinear with fragmentary, horizontal free-edge portion 54 forming a portion of the upper margin of gluefiap panel 20. The glue-flap panel 20 has cut from the marginal portions 32 and 54, a substantially rectangular segment 55 which is the same dimensions as portion 56 (see upper right-hand corner of FIGURE 8), which will subsequently be described in detail and which has a particular function with respect to the erected and assembled carton.

The first side Wall panel 12 has extending transversely across the upper portion thereof and parallel to the foldline 50 and the margin 30, a manually-separable perforated line 58, forming a separable panel segment portion 60. Likewise, the glue-flap panel 20 has extending parallel .to the free marginal portion 54, and in colinear relationship to the perforated, severable portion 58, a fragmentary, severable portion 66, which extends between the fold-line 28 and the adjacent vertical portion of the rectangular segment 55. The second end wall portion 16 has extending transversely thereacross, parallel to the foldline 50 and disposed somewhat below the severable portions 58 and 62, a manually-severable perforated line 64.

The severable line 62 forms a severable or separable panel segment 66, and the severable line 64 forms a panel portion 68 which will ultimately appear at the rear of the hinged lid of the carton, as will be apparent during the description of the erected carton. Extending from the terminal ends 70 and 72 of line 64 and extending angularly and upwardly to the terminal ends 74 and 76 of lines 58 and 62, respectively, are manually severable, diagonal perforated lines 78 and 80 which, respectively, form side wall segmental panel portions 82 and 84, of the hinged lid.

The first end wall panel 12 has hingedly connected at the upper marginal fold-line 50, a rectangular or square top or cover panel 88 having a free margin 90 extending from the fold-line. 50 to an upper free edge 92 extending the'entire width of the closure flap 88. The segment 82, i.e., the upper margin of the first side wall panel 14, has connected at the fold-line 50 a cover panel 94 which has a pair of fragmentary free marginal portions 96 and 98 formed by cut lines in colinear alignment with the free margin 92 and terminating in opposite ends of a score or fold-line 100. Depending from the fold-line 100 are a pair of die cuts 102 and 104 which terminate in a transverse fragmentary hinge or fold-line 106 parallel to the fold-line 100 and forming in the panel 94 a stabilizing panel element 108 which faciliates the assembly of the novel carton.

The second side wall panel 18 has hingedly connected at the upper margin of segment 84 at the fold-line 50, a transversely disposed rectangular cover panel 110, the upper margin of this cover panel being defined by a transverse die cut 112; this will be the outermost panel of the hinged lid as will subsequently become apparent.

The second end panel 16, i.e., at the upper edge of the panel segment 68, has hingedly secured at the hinge line 50 a rectangular panel 114 conveniently described as a toggle-and-restraining panel which is formed with free side margins 116 and 118 separating the panel 114 from flanking panels 94 and 110, respectively. The panel 114 has formed thereon by means of suitably scored foldlines a first transverse fold-line 120 forming a panel segment 122, and a second transverse fold-line 124 forming a pair of narrower panel segments 126 and 128.

Hingedly connected at the fold-line 100 at the top of panel 94 and an upper transverse fold or score line 130 forming the upper edge of panel segment 128 is a rectangular sleeve-simulating side panel segment 132, hinged at 100 and bordering or overlying panel segment 94, and

a rear panel segment 134 overlies the panel 114 and is hinged at 130, as previously mentioned. A second simulated-sleeve panel segment 136 overlies the cover panel 110 and is separated therefrom by the transverse cut 112, and finally a square or rectangular panel segment 138 is spaced vertically from the glue-flap panel 20 and is connected to panel segment 136 at fold-line 144.

The panels 132, 134, 136 and 138 are hingedly connected to each other by means of vertically extending fold-lines 140, 142 and 144, respectively. The panel segment 132 has connected thereto in alignment with the free edge portion 146 thereof, the previously mentioned rectangular segment 56, this segment being connected to the free edge by means of a crease 148.

Assembly and erection of the carton First comparing FIGURES 8 and 9; the first fold is made on fold-lines 106 and 120. The panels 132-138 will have applied, as seen in FIGURE 8, spots of a suitable adhesive as indicated at 150; it being noted that the panel 134 has a strip of adhesive material 152 across the upper edge.

When the first fold is made, on lines 106 and 120, as clearly indicated in FIGURE 9, in the assembled carton, panels 132-138 will comprise a simulated sleeve projecting vertically above the upper marginal outer portion of the carton after the lid has been pivoted away from the contents-containing portion, as seen, for example, in FIGURE 2.

It will be noted that. the portion 56 will now be disposed in overlying relationship with respect to the perforated, severable line 58, on the end wall 12, and will be disposed in a substantially mirror-like position with respect to the rectangular recess 55. As will subsequently become apparent, when the carton is finally assembled, portion 56 will be received within the rectangular cutout portion 55, and the portion of panel 138 adjacent to the rectangular cut-out will be disposed adjacent and coplanar with the portion 56, with the parts disposed in the position shown in FIGURE 9, panels 88, 94, 126, 128 and 108 and panel will provide the top closure flaps for the erected carton. The glue spots and strip 152 will adhere to underlying portions.

Referring to FIGURE 10, the glue-flap panel 20 is next folded on fold-line 28 so that panel 20 overlies side wall panel 18.

Next, in order to complete the formation of a rectangular tube, panels 14 and 12 are folded in coplanar relationship into overlying relationship on panels 16, 18 and 20 at fold-line 24, as seen in FIGURE 11. The panel 12 will adhere to glue-flap panel 20, and the rectangular portion 56 will fill the rectangular notch 55 at the top of panel 20 and adhere to a portion of panel 138.

In order to erect the assembled rectangular tube, the side walls 14, 18 and end walls 12, 16 are disposed in mutually parallel relationship, see FIGURE 12. The panel segments 136, 138, 132 and 134 form a simulated sleeve; see FIGURE 2. The panel segments 122, 126, 128 will engage at their outer ends on the upper edges of panels 132 and 136, as indicated at 132' and 136' in FIGURE 12.

The bottom closure panels are folded and conventionally glued in overlying relation as seen in FIGURE 12. Next, panels 126, 128' are folded onto edges 132' and 136 as previously mentioned. Panel 88 is next folded inwardly onto the upper edges of sleeve panels 132, 136 over the upper edge of panel 20 and segment 56. Next, panel 94 is folded onto and preferably glued to panel 88 and panel 122.

Finally, panel 110 is secured onto panel 94 to complete the hinged lid, as shown in FIGURE 1.

In order to open the carton to the condition shown in FIGURE 2, the tear lines 58, 78, 80, 100 and 62 are ruptured and the sleeve formed from portions132, 134, 136, 138 and segment 56 adheres to the inner surface of Walls 14, 16, 18 and 12, respectively. The segment 56 will complete the front of the sleeve and the segment 108 remains with the end panel 136. The sleeve formed with the side and end wall panels aids to form a good seal when the hinged lid is reclosed. It will be noted that segment 108 stabilizes the initial fold described above, and subsequently, this segment is detached from panel 132 when the lid is opened.

When the lid is hinged or pivoted open, see FIGURES 1, 2, 4 and 6, the panel segments 128, 126, 122 will assume the intermediate posit-ion shown in solid lines on FIGURE 6. Continued movement of the lid toward an open position results in the panel element moving suddenly to the right angular postion of FIGURE 4, i.e., a toggle action over the sleeve edges 132', 136', causing the lid to snap open. The panel segments 126, 128, 122 retain the lid in the open condition shown in FIGURES 2 and 4.

Reclosing of the lid causes a snap action from the solid line position of FIGURE 4, toward that of FIG- URE 6.

The panelsegments 126 and 128 have a combined length greater than the arc of the :hinged lid at which these panel segments are located and thus there is a slight toggle action of these segments 126, 128, 122 as the lid is hinged. The panel segments 122, 126 and 128 retain the lid against excessive pivotal movement on hinge line 64.

There has been disclosed a novel carton and blank which fully conform with the objects of invention.

Obviously, many modifications may be made without departing from the basic spirit of the present invention, and therefore, within the scope of the appended claims, the invention may be practiced other than has been specifically described.
