BACKGROUND OF THE INVENTION 
     This invention pertains to cardboard boxes, and more particularly, to a display carton. 
     Numerous products displayed in stores, such as video tapes, toys, groceries, etc. are typically shipped to the stores in cardboard boxes. At the stores, the products are tediously unpacked and removed from the boxes and stacked on a shelf, stored in a bin, or placed on a separate display stand. The boxes are subsequently collapsed and usually discarded. This procedure is cumbersome, laborious, and inefficient. It requires extra labor, extra supervision, and extra space to store and dispose the cartons. Disposal of cartons is wasteful. The use of bins, such as in discount stores, is unattractive and decreases the appeal of the merchandise. The use and replacement of separate display stands is expensive. 
     Over the years a variety of cartons and containers have been suggested with windows or other devices for viewing or displaying merchandise. These prior cartons and containers have met with varying degrees of success. They usually have not been, however, aesthetically appealable or successfully marketable without a display stand. 
     It is, therefore, desirable to provide an improved carton which overcomes most, if not all, of the preceding problems 
     SUMMARY OF THE INVENTION 
     An improved display carton provides a strong sturdy container for safe and dependable shipment of merchandise and an attractive display case and stand for displaying the merchandise shipped in the container. Advantageously, the novel display carton is easy to use, aesthetically pleasing, attractive, economical, and effective. It is simple to assemble and readily changeable from a shipping box to a display case. 
     To this end, the novel carton has lateral walls, end walls, and side walls, with at least one of the walls comprising a moveable display panel. Desirably, the moveable display panel is pivotable from a normally closed shipment position to an open display position. In the closed shipment position, the outer exterior surface of the display panel blocks access to the interior of the carton. In the open display position, the inner display surface of the display panel provides a wall to support and display at least some of the merchandise in the carton. 
     In the preferred form, the display carton provides a stable, steady, display stand, rack and easel, which extends above the top of the box to display the merchandise. Desirably, the display case has an access opening and window for viewing the remaining merchandise in the box. 
     A more detailed explanation of the invention is provided in the following description and appended claims taken in conjunction with the accompanying drawings

     A rectangular bottom panel 110 is integrally hinged and connected along a bottom, forward horizontal score 112 line to the bottom of said chin panel 62. The bottom panel provides the bottom lateral wall of said carton, container, and box. An elongated generally trapezoidal-shaped glue flap 114 is integrally hinged and connected along a bottom, rearward, horizontal score line 116 to the bottom of the bottom panel. The bottom panel is glued or otherwise fixedly secured to the bottom inner surface of said back wall 18. 
     A lower left, transverse glue flap 118 is integrally hinged and connected along a left, bottom horizontal score line 120 to the left side of the bottom wall. A lower right, transverse glue flap 122 is integrally hinged and connected along a right, bottom horizontal score line 124 to the right side of the bottom wall. The transverse glue flaps 118, 120, 46 and 50 are generally foot-shaped and similar in size. Each of the transverse glue flaps has a rectangular-shaped ankle portion 125 with a transverse outer edge 126 spanning approximately the same distance as the lateral width of said forward and rearward flaps. The ankle portion has a slanted edge 128 which extends at an angle of inclination ranging from about 45 degrees to about 75 degrees and has a front edge 130 which is aligned with the edges 131 (FIG. 3) of the left or right side flaps. In the illustrative embodiment, the slanted edges are positioned at an angle of about 60 degrees relative to the transverse outer edges. 
     When the box is assembled, the right glue flaps are positioned transversely across and secured to the right side flaps and the left glue flaps are positioned transversely across and secured to the left side flaps. The outer surfaces of the glue flaps are glued or fastened to the inner, inwardly-facing, surfaces of the side flaps. 
     As shown in FIGS. 2 and 3, when properly assembled and fastened to each other, the left side flaps and left glue flaps form the left side wall 132 of the shipping box, container, and display case, and the right side flaps and right glue flaps form the right side wall 133 of the shipping box, container, and display case. 
     In order to efficiently and aesthetically display the merchandise in the box at a store, without the use of a separate exterior display stand, rack or bin, the front display panel, forehead panel, upper panel, and ears are partially detachable from the box to provide an attractive, sturdy display stand 16 (FIG. 3). The display stand extends upwardly from the top panel of the display case 14 and when detached from the front wall of the box provides an access opening and window 134 for viewing the contents inside the display case. 
     When the carton and display stand are in the open display position as shown in FIG. 3, the inner support surface 136 of the front display panel provides a back support portion to support and display some of the merchandise that was shipped in the box. The inner support surface can have a sign, advertisement, promotional material, pricing information, product descriptions, writing, or other indicia printed thereon. When the carton and stand are in the closed shipment position as shown in FIG. 2, the outer exterior surface 138 of the front display panel provides a barrier portion which blocks and prevent access and viewing through the opening and window of the front wall of the box. 
     As shown in FIG. 3, the forehead panel 54 of the display stand provides a rearward support ledge 140 which extends forwardly at an upward angle of inclination from the bottom of the front panel of the display case. The rearward support ledge carries and help support merchandise on the display stand. 
     The upper panel 40 of the display stand provides a forward ledge and lip 142 which extends forwardly of the rearward support ledge at a downward angle of inclination. The top of the lip is integrally hinged and connected to the rearward support ledge. The bottom of the lip is integrally hinged and connected to the top panel of the display stand. Writing or other indicia can be printed on the lip. 
     The ears 76 and 96 provide support legs and sides of the display stand to support the front display panel at a rearward angle of inclination. The locking tabs 78 and 98 of the ears are inserted into and lockably engage the locking tab-receiving holes 32 and 33, or 34 and 35, to securely fasten and lock the support legs of the display stand to the top panel of the display case. When the locking tabs are inserted into and lockably engage the rearward set of locking tab-receiving holes 32 as shown in FIG. 4, the included angle between the rearward and forward ledges is an obtuse angle. When the locking tabs are inserted into and lockably engage the optional forward set of locking tab-receiving holes 34 as shown in FIG. 5, the included angle between the rearward and forward ledges is an acute angle. 
     Most preferably, there is only one set of locking tab-receiving holes to enhance the structural strength, rigidity, and mechanical integrity of the carton and display case. The set of locking tab-receiving holes can be positioned in accordance with the preference of the customer to attain the desired angle of inclination of the display panel. While one set of locking tab-receiving holes is preferred for best results, it may be desirable in some circumstances to include one or more additional sets of locking tab-receiving holes or knockouts therefore, although the strength of the box will be somewhat reduced. 
     In the illustrative embodiment, the elongated upright edges 144 (FIGS. 3-5) of the support legs (ears) are positioned at an angle of about 15 to 30 degrees relative to the outer edges of the display panel and the top panel-engaging bottom edges 146 of the support legs, adjacent the locking tabs, are perpendicular to the upright edges of the support legs, so that the display panel is positioned at a rearward angle of inclination of about 60 to 75 degrees relative to the vertical axis. While these angles are preferred, in some circumstances it may be desirable to use other angles. 
     If desired, the central middle knockout sections 147 and 148 (FIG. 3) of the main body portions of the forward side flaps can be detached from optional slanted perforation lines 149-152 and removed from the display case, to provide a larger opening and window through the sides of the display case for viewing the contents inside the display case. In the illustrative embodiment, the slanted perforation lines are at an angle of inclination of about 30 degrees relative to the vertical axis and edges of the side flaps and are aligned in registration with the slanted edges of the glue flaps. The knockout sections are generally trapezoidal in shape. 
     In use, the carton is assembled to from a box-like shipping container as shown in FIG. 2 for shipment and storage of merchandise. When the container arrives at the store, the display panel, forehead panel, and ears are detached from the container and pivoted upwardly to form an attractive display case with a front window (opening) and an upwardly extending display stand as shown in FIG. 3. Merchandise shipped in the container is neatly stacked and attractively displayed upon the display stand. 
     Among the many advantages of the display carton are: 
     1. Improved transport and display. 
     2. Economical to manufacture. 
     3. Cost effective. 
     4. Savings of storage, shelf space, and material.
