HEXAGONAL CONTAINER FOR FOOD PRODUCTS OR THE LIKE BACKGROUND OF THE INVENTION This'invention relates to containers and, more particularly, to cartons for packaging foodstuffs and the like.
In many instances it is desirable to package foodstuffs and the like in canister or box-like containers that can be readily opened yet that are recloseable if the contents thereof is not immediately consumed. One typical instance is the fast-food service establishments where a consumer can purchase a pre-prepared meal such as fried chicken, for example, in a carry-out container. At the same time, in large volume operations, it is desirable that unused cartons be collapsible for shipment and storage, yet the cartons must be readily erectable when needed.
It is an object of the present invention to provide a collapsible, yet readily erectable container which is formed from an integral blank of a foldable material and which is provided with a self-locking, foldable end closure.
It is a further object to provide a container with exposed peripheral surfaces that are available for the display of promotional materials.
Still other objects will readily present themselves to one skilled in the art upon reference to the ensuing specification, the drawings, and the claims.
SUMMARY OF THE INVENTION The present invention contemplates a carton adapted to be erected from a unitary or integral blank and having six hingedly connected side panels which together define a substantially hexagonal cross-section when the carton is erected. The carton may have either straight or tapered sides, depending on the intended use. The present carton is provided with a self-locking foldable top end closure which is connected to the side panels and comprises first and second closure flaps, each hingedly connected to an opposing side panel and adapted to overlap when folded and a pair of web means associated with each closure flap, each web means being hingedly connected between the closure flap and the side panel adjacent to the side panel which isconnected to the closure flap. A pair of outwardly extending locking tabs are provided on opposing sides of the second closure flap and a pair of locking tab retaining flaps are provided on the web means associated with the first closure flap.
Preferably, the closure flaps are hingedly connected to their respective side panels along a curved score line.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the following description reference will be made to the accompanying drawings for a better understanding of this invention. In the drawings all parts are numbered, and the same numbers are used to identify the same parts in the several FIGURES. Additionally, areas having an adhesive applied thereon are indicated by stippled shading.
Referring to FIG. 1, an integral carton blank 10 cut and scored so as to provide a carton of the present invention comprises six side panels 11, 12, 13, 14, 15 and 16 hingedly connected by means of creased score lines l7, l8, 19, 20 and 21. Glue flap 22 is provided alongside side panel 11 and is hingedly connected thereto by creased score line 23. Adhesive region 24 on side panel 16 is adapted to contact and secure glue flap 22 when blank 10 is folded over.
Closure flap 25 is hingedly connected to side panel 14 along creased score line 26 which is preferably curved so as to gain additional pull strength. Closure flap 25 is also provided with locking tabs 27 and 28 situated diametrically opposite each other along the sides of flap 25. Creased score lines 19 and 20 may be extended so as to traverse also flap 25 in order to facilitate the manipulation thereof; however, this isoptional. Web means 29 and 30, preferably trapezoidal in shape, are also associated with closure flap 25 and are hingedly connected by means of creased score lines between flap 25 and side panels 13 and 15, respectively. Cut- outs 31 and 32 in flap 25 provide finger grip means for carrying the erected carton.
Another closureflap, flap 33 (FIGS. 3, 4 and 5), is constructed upon gluing from flap means 34 which constitutes a major portion thereof and is hingedly con- I nected to side panel 11 (FIGS. 1 and 2) by creased score line 35 which is preferably curved. Web means 39 is hingedly connected between flap means 34 and side panel 12. If desired, creased score lines 17 and 23 may be extended so as to traverse flap means 34 in a manner similar to flap 25. Appendage 36 constitutes a minor portion of flap 33 and is hingedly connected to web means 37 along a creased score line. Web means 37, in turn, is hingedly connected to side panel 16 by a creased score line. Adhesive region 38 on appendage 36 is adapted to contact and secure flap means 34 when blank is folded over. Appendage 36 and flap means 34 when glued together form closure flap 33. Cut- outs 40 and 41 in flap means 34 are adapted to be substantially coextensive with cut- outs 31 and 32 when blank 10 is folded over and provide finger grip means for carrying the erected carton.
Web means 37 and 39 are preferably triangular in shape, and are provided with locking tab retainer means 42 and 43, respectively, along the free sides thereof, which retainer means are adapted to removably engage locking tabs 28 and 27, respectively, thereby securing closure flap 25 in a folded down position.
Bottom closure flaps 44, 45, .46, 47, 48 and 49 are hingedly connected to respective side panels l1, 12, 13, 14, and 16. Flaps 45 and 48 are provided with quadrilateral glue tabs 50 and 51 hingedly connected thereto along lines of perforations. Flap 47 is provided with a substantially trapezoidal glue tab 52 hingedly connected thereto along a perforated line. Preparatory to folding and gluing of the carton blank, bottom closure flaps 44, 45, 46, 47, 48 and 49 are folded inwardly as shown in FIG. 2 with glue tabs 50, 51 and 52 folded back against their respective flaps thereby exposing the adhesive regions of these tabs. When blank 10 is folded over, glue tab 50 is adapted to contact and adhesively secure bottom closure flap 46, glue tab 51 is adapted to contact and adhesively secure bottom closure flap 49, and glue tab 52 is adapted to contact and adhesively secure bottom closure flap 48. With the flaps and the respective tabs arranged in the foregoing manner the gluing can be effectively carried out on the socalled right-angle gluing machine. A folded over and glued carton blank is shown in FIG. 3.
When it is desired to erect a carton from the folded over and glued carton blank, the outer edges thereof are simply pushed towards each other whereupon the carton bottom automatically snaps in place and the carton assumes the configuration shown in FIG. 4. The desired contents can then be placed in the erected carton and closure effected by first folding down closure flap 33 and then closure flap 25 so that the finger gripping means of both flaps are in substantial registry and locking tabs 27 and 28 snap under the respective locking tab retainer means 43 and 42. The closed carton is shown in FIG. 5.
Another embodiment of the present invention is shown in FIGS. 6, 7, 8, 9 and 10. In these FIGURES, the reference characters used in connection with the various parts are correlated to like parts shown in FIGS. 1 through 5 by using the lOO-series of reference characters. That is, like parts of carton blank 10 and carton blank 100 are designated by reference characters XX and IXX, respectively. For example, glue flap 22 of blank 10 is similar to glue flap 122 of blank 100. Thus no further description of the like parts and their interaction is necessary inasmuch as the foregoing description of blank 10 is equally applicable to blank 100.
tion of flap means 134 and closure flap 125 when folded thereover. Preferably at least portions of members 153 and 154 are covered with an adhesive and are adapted for adhesive affixation to flap means 134 and closure so that openings 155 and 156 of member 153 are in substantial registry with cut-outs and 141 and'so that openings 157 and 158 of member 154 are in substantial registry with cut- outs 131 and 132, respectively. Of course, the strengthening members such as 153 and 154 need not be hingedly connected to flap means 134 and closure 125 but can also be fabricated of a separate piece of paperboard or the like and then adhesively affixed in place.
A The foregoing description and the drawings are intended as illustrative but are not to be construed as limiting. Still other variations within the spirit and scope of this invention will readily present themselves to one skilled in the art.
