Cl. 229-41 Claims ABSTRACT OF THE DISCLOSURE This invention comprises a hexagonal one-piece carton designed to enclose a cylindrical or hexagonal product such asan ice cream cake roll or the like. The carton includes two semihexagonal tray "sections foldably connected. The arrangement is such that as the ends of the two sections are folded outwardly into parallel relation, the sections automatically fold into semihexagonal shape for filling. The sections are then folded together, and a glue flap on one section is adhered to a panel of the other section. A tear strip permits separation of the glue flap for opening the carton. Locking means are provided for reclosing.

This invention relates to an improvement in hexagonal one-piece cartons and deals particularly with a carton designed to contain a generally cylindrical or hexagonal product such as an ice cream cake roll and the like.

Products such as ice cream cake rolls and the like which are of generally cylindrical formare diflicult to package in conventional rectangular cartons. Due to the cylindrical shape of the product, they'require a rectangular carton considerably larger than the product itself. Furthermore, a rectangular carton does not provide a particularly good support for the product in the event the product softens. Obviously, a carton of hexagonal cross section provides much better support for the product and leaves considerably less waste space between the product and the walls of the carton. Due to the fact that products of this type 'are specialty items, they are often times not sold in suflicient quantity to require automatic machinery to seal.- It is an object of the present invention to provide a hexagonal carton which may be glued and stored in fiat form, and which may be manually erected for filling, and manually closed after filling.

A further feature of the present invention resides in the provision of a carton of the type described which includes locking means for holding the carton reclosed. In many instances only a part of the product is used at one time, and the remaining product must be effectively contained until the rest of the contents are used. I provide a novel and effective lock which may be used to hold the carton reclosed after it has been once opened and after a portion of the carton contents has been removed.

A further feature of the present invention resides in the provision of a carton which may be glued in flat form, and which may be manually erected to provide a pair of side by side tapered tray sections hingedly connected together. When in this condition, the product is inserted in one of the tray sections, and the other tray-like sections may be folded to enclose the contents. In forming the carton from fiat position into position to contain the contents, the ends of the carton automatically fold into right angular relation to the hexagonally arranged side walls. The closure may be completed by adhering a glue fiap on one of the sections in face contact with the adjoining wall of another section, the carton being thus sealed. Preap'plied adhesive may be employed if desired. In preferred form, the glue flap includes a removable tear strip which may be detached to allow the two sections to 3,467,298 Patented Sept. 16, 1969 fold apart. A supplemental lock is provided which may be used in the event the carton is to be reclosed.

These and other objects and novel features of the present invention will be more clearly and fully set forth in the following specification and claims.

FIGURE 2 is a perspective view of the carton in position for receiving the carton contents.

FIGURE 3 is a cross sectional view through the closed carton.

FIGURE 4 is a diagrammatic view of the carton blank from which the carton is formed.

FIGURE 5 is a diagrammatic view showing the bank after the fiat blank has been folded.

FIGURE 6 is a plan view of the carton after it has been reclosed.

The hexagonal one-piece carton is indicated in general by the letter A. The carton A was originally designed for containing an ice cream cake roll which is shown in broken lines in FIGURE 3 of the drawings and indicated by the letter B. Obviously, the carton could be used for other products.

The carton A is foldable into two tray-like sections as shown in FIGURE 2 of the drawings prior to filling and closing. These sections may be considered to comprise a bottom section 10 and a top section 11 which are foldably connected along a line of fold 12. Obviously, the terms are merely relative. The bottom tray section 10 includes a rectangular bottom panel 13 and a pair of upwardly and outwardly inclined rectangular

side wall panels

14 and 15 connected to the bottom panel 13 along

parallel fold lines

16 and 17. A tuck flap 19 which is substantially equal in width to the

panels

13, 14, and 15 is provided with generally diagonal corners 20 designed to simplify the manual closing of the carton.

The walls which have been described are defined at their ends by a pair of parallel fold lines 21. Hexagonal end wall panels 22 are foldably connected to the ends of the bottom panel 13 along these fold lines 21. A pair of triangular gusset panels 23 are hingedly connected to the ends of the side wall 14 along extensions of the fold lines 21, and similar trianguar gusset flaps 24 are hingedly connected to the gusset flaps 23 along inclined fold lines 25, and are hingedly connected to an edge of each hexagonal end wall 22 along inclined fold lines 26. The triangular gusset flaps 23 and 24 are of equal size and fold int-o face contact when the carton is erected, as will be later described. The fold lines 21 and 25 are at an angle of 30, as are the

fold lines

25 and 26.

A similar gusset flap construction is provided between the ends of the side wall 15 and the hexagonal end wall 22. Triangular gusset flaps 27 are foldably connected to the ends of the side wall 15 along extensions of the fold line 21. The gusset flaps 27 are hingedly connected along fold lines 29 to similar gusset flaps 30, the gusset flaps 30 being foldably connected to an edge of the hexagonal end wall 22 along inclined fold lines 31. The

gusset flaps

27 and 30 are also of similar size and shape and are designed to fold into contiguous relation when the carton is set up, as will be later described. The fold lines 21 and 29 define an angle of substantially 30, as do the fold lines 29 and 31.

Triangular corner flaps 32 are foldably connected to fourth sides of the hexagonal end panels 22 along fold lines 33. Generally triangular closure flaps 34 are foldably connected along fifth edges of the hexagonal end walls 22 along fold lines 35. The purpose of the flaps 32 and 34 is to overlap adjoining walls of the hexagonal carton when it is closed so as to avoid any area of exposure of the carton contents. Triangular flaps 36 are also provided connecting the ends of the gusset flaps 27 to the ends of the tuck flap 19. The triangular fiaps 36 are defined by extensions of the fold line 37 connecting the tuck fiap 19 to the side wall 15, and extensions of the fold lines 21.

The other tray section 11 is somewhat similarly made. Tray section 11 includes a top panel 40 which is hingedly connected along opposite edges by fold lines 41 and 42 to

rectangular wall panels

43 and 44 respectively. The wall panel 4 is hingedly connected along the fold line 12 to the wall panel 14. The wall panel 43 is hingedly connected along a weakened line of separation 45 to a removable tear strip 46, the other edge of which is connected along a weakened line of separation 47 tothe glue flap 49. Diagonal fold lines 50 extend across the Wall panels 43 from the juncture of the fold lines 21 and 41, the fold lines 50 being at an angle of 30 from the fold lines 21. Substantially trapezoidal closure flaps 51 are hingedly connected to opposite ends of the wall panel 43 along a fold line 21. The closure flaps 51 are separated from the remainder of the closurefiap structure by cut lines 52 forming the continuation of the fold line 41.

The top panel 40 and adjoining wall panel 44 are hingedly connected along each fold line 81 to a flap structure which is indicated in general by the numeral 53. Each flap structure 53 includes a trapezoidal flap 54 having an outer edge which is parallel to, and is considerably wider than, the width of the top panel 40. An edge of each trapezoidal flap 54 is connected by a fold line 55 to the remainder of the flap structure, the fold lines 55 being at an angle of substantially 30 from a continuation of the fold line 42. A triangular gusset flap 56 is hingedly connected to the wall panel 44 along the fold line 21, and a similar triangular gusset flap 57 is hingedly connected to the flap 56 along a fold line 59, and is connected to the adjoining trapezoidal flap 54 along the fold line 55. The gusset flaps 56 and 57 are of equal size and are designed to fold into contiguous face contact when the carton is erected. The angle defined by the fold lines 21 and 59 is substantially 30 as is the angle between the fold lines 55 and 59.

A triangular locking tongue 60 is hingedly connected to the wall panel 43 along a fold line 61 which is parallel to the fold line 41. Laterally extending generally triangular locking wings 62 are connected to opposite edges of the locking tongue 60 along converging fold lines 63.

One side of the locking 'wings 62 is defined by the weak ened line of separation 45 so that when the tear strip 46 is removed, the locking tongue and the locking wings are free to hinge along the fold line 61.

The tuck flap 19 is provided with a pair of angularly inclined converging cut lines 64 which are designed to accommodate the locking wings 62 for reclosing the carton. These cut lines 64 are normally concealed within the package until the carton is first opened.

In the gluing of the flat carton, the closure flaps 51 together with the triangular areas 65 outwardly of the fold line 50 are folded along the fold lines 50 so that the trapezoidal closure flaps 51 overlie a portion of the wall panel 43 and a portion of the top panel 40, the angularly extending edges 66 which are substantially at an angle of 60 from the fold lines 21 extending generally parallel to these fold lines as is indicated in FIGURE of the drawings. Areas of adhesive 67 are applied to the trape-- zoidal flaps 54, and the flap structures 53 are folded to overlie the closure flaps 51 and are adhered in surface contact thereto. Areas of adhesive 69 are applied to the triangular gusset flaps 56, and these gusset flaps 69 are adhered in face contact to the wall panel 44.

Areas of adhesive 70 are applied to the gusset-flaps 23, and similar areas 71 are applied to the gusset flaps 27. The flap structures are folded inwardly along the fold lines 21, and the

flaps

23 and 27 are adhered in face contact to the wall panels 14 and respectively. After the folding operation, the carton appears as indicated in FIGURE 5 of the drawings.

When the carton is to be used, it is normally folded into the form illustrated in FIGURE 2 of the drawings, the carton then havingtwo

tray sections

10 and 11 connected by the fold line 12. The tray section 10 has full hexagonal end panels 22, while the tray 2 section 11 has semi-hexagonal end portions. The product B is then placed in the carton, the product usually being placed inthe tray section 10. The triangular flaps 32 and 34 are then bent into right angular relation to the end panels 22 the flaps then being in the position indicated in FIGURE 2 of the drawings. The tuck flap 19 is next folded to overlie the triangular flaps 34,- and the cover section 11 is swung this operation the carton may be rolled over to rest upon' the wall panel 14 as shown in FIGURE 1 of the drawings. In other words, while the

wall panels

13 and 40 have been described as the-bottom panel and top panel respectively, this terrn is merely a relatively'term' to sim-' plify the description. a

The anchoring flap or glue flap 49 may have preapplied hot melt adhesive thereon if desired. This permits the flap to be adhered to the panel 15 by the use of heat and pressure sufiicient to render the adhesive tacky.

When it is desired to. open the carton, the tear strip 46 is removed, leavin the anchoring flap adhered to the wall panel 15. The carton may be'opened' up and the contents removed or partially removed. If his desired to reclose the carton, this is done by folding the locking wings 62 into substantially right angular relation to the locking tongue 60, and inserting these wings'throu'gh the slots 64 to lock the carton in reclosed position. When reclosed, the carton appears as indicated in FIGURE 6 of the drawings.
