Nov. 28, 1967 R. B. INGLE 3,355,086

CARTON Filed June 21, 1965 INVENTOR. ROBERT B, INGLE RONALD E. BARRY ATTORNEY United States Patent 3,355,086 CARTON Robert B. Ingle, Fort Worth, Tex., assignor to Hoerner- Waldorf Corporation, St. Paul, Minn, a corporation of Delaware Filed June 21, 1965, Ser. No. 465,311 6 Claims. (Cl. 229-31) This invention relates to an improved construction for a carton or container which can be formed from a single, precut blank of carton forming material.

The cartons contemplated herein are used by retail stores to Wrap suits or dresses and are assembled by the clerk and given to the purchaser. Cartons of this type generally include advertising material printed on one side and are made of a light weight carton forming material in order to provide a printable surface. These cartons are not designed to carry any substantial weight but must be strong enough to maintain their shape under ordinary loads in order to protect the suit or dress which is to be carried within the carton.

One of the principal objects of the present invention is to provide an improved type carton which is made from a single blank of light weight carton forming material and has sufficient rigidity to withstand normal loads.

Another object of the present invention is to provide a carton which will retain its shape under normal loads.

Still another object of the present invention is to provide a carton that can be formed from a single blank of carton forming material in a minimum of time and little effort.

A further object of the present invention is to provide an improved carton for carrying dresses or the like which is substantially sealed at all corners to prevent foreign matter, such as dust, from entering the carton.

A still further object of the present invention is to provide an improved carton which can be formed from a single blank of carton forming material with the bottom and top side walls automatically locked in their upright positions.

A still further object of the present invention is to provide a carton blank which can be formed into a carton for carrying dresses or the like that has the top wall locked to the bottom wall.

These objects are accomplished by cutting and scoring a carton blank of light weight carton forming material with the top and bottom side walls interconnected by an end wall flap that is integral with the carton blank. The end wall flap is divided by diagonal score lines into equal quadrants that fold' to an overlapping relationship to hold the top and bottom side walls in an upright position. The overlapping action is automatically accomplished as the carton is folded and will hold the side walls in the upright position under considerable loads. The other end of the bottom side walls are also held in position by folding the front wall into overlapping relation with dust flaps which are connected to the bottom side wall flaps.

A carrying handle is also provided in the front flap on the top wall which also acts to lock the top wall to the front wall on the bottom wall when the carton is closed. The handle is so located on the top wall that it will project through an opening in the front Wall. This arrangement for closing the top wall provides a distinct advantage in that no special attaching means is required to hold the carton closed.

Other objects and advantages will become more readily apparent from the following detailed description when read in connection with the accompanying drawings, in which:

FIG. 1 is a plan view of a carton blank cut and scored to form the carton of the present invention.

FIG. 2 is an isometric view of the carton blank folded to form the carton.

Referring to the drawing in detail, the carton is shown formed from a unitary, rectangular cardboard blank which is provided with transverse score lines 10, 12, 14, 16, 18 and 20 to form front flap 22, top wall 24, end wall 26, bottom wall 28, front wall 30, connecting wall 32 and lock flap 34.

Longitudinal score lines 36 and 38 are provided a spaced distance inward from the longitudinal edges of the carton blank to form side walls 40 and 42, bottom side walls 44 and 46 and end wall flaps 48 and 50. These score lines are extended by cuts 52 and 54, respectively, to form dust flaps 56 and 58 which are hingedly connected to the bottom side walls by score line 16.

The end wall flaps are each divided into quadrants 48a, 48b and 480 and 50a, 50b and 50c with a hole 49 and 51 cut out of the center of each end Wall flap. The quadrants are separated by diagonal score lines 47 and 53, respectively, which are angled outward at a forty-five degree angle from the intersection of score lines 12 and 14 with score line 36, so that the fold line will lie on score line 12 or 14 when the carton is erected.

The lock flap is provided with tabs 62 on its outer edge 60 which are inserted into slots 64 in the bottom wall when the front wall is erected. The connecting panel 32 separates the lock flap from the front wall, forming a space for the dust flaps 56. A handhole 66 is provided in the lock flap which is aligned with an opening 68 in the front wall. A closure flap 70 is hingedly connected to the front wall at score line 72 with a finger notch 74 provided in theflap to open it.

A pair of slots 76 are cut in the front flap which will also be aligned with holes 66 and 68 when the carton is erected. Flexible plastic handle 76 having flanges 78 at each end is mounted in the flap by inserting the flanges into the slots. Since the handle is flexible it can be easily attached to the front flap by merely twisting the ends and inserting them through slots 76.

In erecting the carton, the bottom side walls and top side walls are folded upward on score lines 36 and 38. Dust flaps 56 and 58 are then turned inward until aligned with score line score line 16 against the dust flaps and connecting panel 32 is folded on score line 18 over the dust flaps. The lock flap is folded on score line 20 until tabs 62 can be inserted into slots 64 With the dust flaps enclosed in the space between the front wall and lock flap. The bottom side walls will be held in their upright position by the dust flap.

The end wall is folded upward on score line 14 with quadrants 48b and 50b folded inward on score line 36 against the inside surface of the end wall. Quadrants 48c and 500 will fold on score lines 47 and 53, respectively, into engagement with the surfaces of quadrants 48b and 5012, respectively. The top wall is then folded on score line 12 with the top side wall folded inside of the bottom side wall and quadrants 48a and 50a folded on score lines 47 and 53 into engagement with quadrants 48c and 500. The action of the quadrants on the end wall Jlap in folding the top wall into position tends to draw the top side wall and bottom side wall tightly against each other to close the carton.

The flexible plastic handle is inserted in the slots in the front flap and the front flap folded downward on score line 10 so that the front flap will fit inside of the front wall. When the top wall has been fully closed, the handle will be aligned in holes 66 and 68 and on opening of flap 78 the carton can be carried by the handle.

Mounting the handle on the front flap so that it projects outward through the holes 66 and 68 also serves to lock the carton closed. The top wall cannot be opened until the 16. The front wall 30 is folded upward on handle has been pushed back through holes 66 and 68 in the front wall and lock flap of the carton.

Although only one embodiment of the present invention has been shown and described, it should be apparent that various changes and modifications of the present invention can be made Without departing from the scope of the appended claims.
