FIELD OF THE INVENTION 
     A wide variety of different types of merchandising units are used to store, dispense, and display consumer goods at the point of sale. For example, in shops and kiosks, the majority of consumer goods are displayed on free standing counter top displays or similar wall mounted display units. However, it may be desirable to dispense certain items from units provided inside the kiosk or behind the counter top area. In such instance, it may be preferred to allow consumers to still view the goods, but not have them directly accessible by the consumer. 
     WORKING ENVIRONMENT 
     It would be desirable to provide a novel merchandising unit for consumer goods and in particular, for smoking articles, which provides increased flexibility in the display and access of the consumer goods at the point of sale. 
     The present invention relates to a folded merchandising unit adapted to be glued and shipped in a folded state and erected at a point of sale into a merchandising display carton. The invention finds particular application as a merchandising unit for smoking articles.

Thereafter, folding the first and second dust flaps  59 ,  69  by an angle of 90° with respect to the first and second side panels  50 ,  60  so as to overlie a bottom of the rectangular opening  110 . The tuck flap  79  is then folded by an angle of 90° with respect to the bottom flap  70  and the bottom flap  70  is folded by an angle of 90° with respect to the third rectangular panel  30  so as to overlie the bottom of the rectangular opening  110  with the tuck flap  79  against an inside of the second rectangular panel  20 . The first rectangular panel  10  is folded by an angle of 180° with respect to the second rectangular panel  20  so as to be inside the rectangular opening  110  against the second rectangular panel  20 . The first, second and third reinforcement sections T 1 , T 2 , T 3  are separated from the remaining portions of the carton blank  100  by tearing the carton blank  100 ′ along the perforation lines P 1 -P 6  and the material removed may be discarded. 
     Referring also to  FIG. 5 , the method further comprises folding the first reinforcement section T 1  90° with respect to the second reinforcement section T 2 ; folding the second reinforcement section T 2  90° with respect to the third reinforcement section T 3 ; and folding the third reinforcement section T 3  180° about the third score line  35  such that the third reinforcement section T 3  abuts an inside of a lower portion of the third rectangular panel  30 , the second reinforcement section T 2  abuts the bottom panel  70 , and the first reinforcement section T 1  abuts a lower portion of the second rectangular panel  20 . The method further comprises inserting the locking tab  21  into the slit  71 . 
     When erected, as shown in  FIGS. 4 and 5 , the merchandising unit includes the glue flap  40  adhered to an inside of the second side flap  60 , and the first and second side panels  50 ,  60  being at an angle of 90° with respect to the second and third rectangular panels  20 ,  30  to form a rectangular opening  110  between the first and second side panels  50 ,  60  and between the second and third rectangular panels  20 ,  30 . The first and second dust flaps  59 ,  69  are at an angle of 90° with respect to the first and second side panels  50 ,  60  so as to overlie a bottom of the rectangular opening  110 , the bottom flap  70  is at an angle of 90° with respect to the third rectangular panel  30  and overlies the bottom of the rectangular opening  110  with the tuck flap  79  at an angle of 90° with respect to the bottom panel  70  and against an inside of the second rectangular panel  20 , and the first rectangular panel  10  is folded over the second rectangular panel  20  and located inside the rectangular opening  110  against the second rectangular panel  20 . 
     Referring to  FIGS. 1 and 5 , the arcuate extent of cut lines C 1  and C 2  can be of sufficient length such that bottom section T 2  may be disposed between dust flaps  59  and  69  so as to provide the unit with a bottom portion of generally uniform double thickness. Such arrangement promotes an even (level) display of product. Perforation (or cut) lines P 5 , P 6  of  FIG. 3  may be sized for similar purpose and effect. In the alternative, the arcuate extent of cut (perforated) lines C 1  and C 2  of  FIG. 1  and the arcuate extent of perforated (or cut) lines P 5  and P 6  may be shortened so as to increase the transverse extent of the bottom section T 2  and increase an overlap of section T 2  over the dust flaps  59  and  69 , to enhance rigidity of the display structure. 
     The merchandising unit or display carton provides a large area on first rectangular panel  10  on which advertisements or merchandising information can be displayed and be viewed above the product P when it is loaded into the carton. The merchandising unit can be displayed on a counter top or, alternatively, holes H 1 -H 4  allow suction cups  200  or other securing means to be used to hang the merchandising unit on a wall surface. Still further, if the merchandising unit is going to be maintained within a kiosk or the like, a rear surface (not shown) of second rectangular panel  20  can be provided with desired advertisements or information. When the merchandising unit is disposed with the rear surface abutting a transparent wall or window, the advertisements or information is viewable to the consumer outside of the kiosk yet the product within the unit can only be accessed by the employee working within the kiosk. 
     While the above blank for the merchandising unit and method of forming the same have been described in detail with reference to specific embodiments thereof, it will be apparent to those skilled in the art that various changes and modifications can be made, and equivalents employed, without departing from the scope of the appended claims.
