Referring to FIGS. 1-11, the dispenser 1 comprises a top section 2 having an opening 3 through which coupons or flexible sheets 4 may be dispensed. The dispenser 1 which is generally rectangular or box shaped, 4 has a stack of flexible sheets disposed one on top of another and folded at a specific length, allowing for the dispensing of individual sheets. In a preferred embodiment of the invention, each coupon or flexible sheet 4 is folded upon itself. The body of the dispenser is preferably made of one unitary piece of material, cut to allow for folding of the material. Creases are made in the appropriate areas of the material to form edges. The material from which the dispenser is made is either paper, cardboard, styrene or plastic.
The dispenser 1 has two long flat end walls 6 and 10. Edges 11 and 12 of these long flat end walls 6 and 10 are positioned perpendicularly to two long flat side wails 7 and 8. The two long flat end walls 6 are parallel to each other, with each of the two long flat end walls 6 and 10 having the same dimensions as the other flat end wall. The two long flat side walls are preferably wider than the two long flat end walls. The two long flat side walls 7 and 8 are parallel to each other, and the two long flat side walls 7 and 8 parallel to one another.
The walls of the dispenser define an opening 3 through which coupons or sheets may be removed. The opening 3 is formed by opposing foldable flaps 9 formed by an extension from and integral with at least one of the walls, preferably from at least one, and most preferably from both long flat end walls 6 and 10. The foldable flaps 9 positioned at a top end of each of the flat end walls, comprises a lip 15 foldable upon flap 9. In a preferred embodiment, there is at least one tab positioned at each corner of a top end of two long flat side walls, resulting in four tabs 16, 17, 18, and 19 such that each foldable flap of a long flat end wall, fold over two tabs, thereby forming the opening of the dispenser.
The dispenser 1 also has a flat bottom wall 13 wherein at least one edge 14 of the flat bottom wall 13 is affixed to the bottom of the dispenser. The flat bottom wall 13 fits within the dimensions of the two long flat side walls 7 and 8 and the two long flat end walls 6 and 10. In a preferred embodiment, the flat bottom wall 13 has bottom wall flaps 20, 21, 22, and 23 positioned around each side of a flat rectangular section 24. One of the flaps 20, 21, 22, and 23 is integrally connected to one of the walls of the dispenser. Each flap of said bottom wall is positioned against an inside section of each of a wall of said dispenser.
In another preferred embodiment, an insertion tab 25 on one of said walls, preferably on said long flat side wall, fits into a slip opening 26 in one of said flaps 20, 21, 22, and 23 of said bottom wall 13, allowing said long flat side wall 7 or 8, (preferably 8) to secure said bottom wall 13 in position.
In another preferred embodiment of the invention, since the dispenser is comprised of a unitary structure, one of the long flat end walls 6 further comprises an extension integral with the other long flat end wall 10, such that the extension forms one of the long flat side walls 8, and an inside support wall 32 for the other long flat end wall. The inside support wall further comprises a flap 33 integral with the inside support wall, with the flap 33 attachable to one of said long flat side walls 7.
At various other locations in and around the dispenser, the glue or tape may be used to secure the various sides or flap of the dispenser. The opposing flaps 9 and lips 15 are glued or taped into position.
A resilient member is used to push the tack of sheets 5 up to the opening 3 in the top wall 2 of the dispenser 1. Any form of spring may be used. In one embodiment of the invention, the member used to push the sheets to the opening 3 of the dispenser is an arc type structure 27 positioned underneath the stack of sheets 5. This arc type structure 27 is positioned between the long flat end walls 6 and 10 and above the flat bottom wall 13. In one embodiment of the invention, one side 29 of the arc type structure is in communication with the bottom of the stack of sheets, wherein the apex 28 of the arc type structure 27 is facing one of the walls of the dispenser, pushing the stack of sheets 5 towards the opening 3 in the dispenser 1. In another embodiment of the invention, the arc type structure 27 may be flexed and inserted between the stack of sheets 5 and the bottom wall 13, such that the apex 28 of the arc type structure is in communication with the stack of sheets.
A filler 30 may be positioned between said resilient member and said bottom wall of said dispenser, thereby putting more stress on the resilient member, which in turns allows the coupons to be dispensed with greater ease. The filler 30 is preferably made of a unitary piece, which folds up to form a small box like structure which fits within the dispenser.
To attract attention, the dispenser may further comprise a specialized advertising tag, known as a shouter 34. The shouter 34 is used to draw attention to the dispenser, and is comprised of a display area for printed matter, known as the head 35, integrally (preferably) attached to a leg 36, wherein one end of the leg is attached to the head, and the other end of the leg is inserted into a slot 37 in the dispenser, allowing for the display of the printed matter. In a preferred embodiment, the shouter further comprises a foot 38, integrally attached to the leg 36 at the end which is inserted into the slot 37 in the dispenser. The foot 38 is a tab which is turned upward, thus serving the purpose of securing the shouter 34 in the dispenser 1. A split 39 in the head 35 from the leg 36 further helps to secure the shouter 34 to the dispenser.
The dispenser 1 is preferably secured to the shelf. There are a number of methods to attach the dispenser to the shelf. One method for attaching the dispenser to the shelf is a rail clip attachment 40 for attachment to a rail of a shelf. The rail clip attachment 40 is attached to the flat bottom wall 13 of the dispenser, and comprises a base member 41, two brackets 42, 43 intersecting and extending outwardly from the base member, the brackets having, at their ends, foot-like projections 44, 45 facing away from each other and fitting into retaining rails of a shelf, at least one hole 46, 47 in each of the brackets, and a screw 48, fitted through the holes in the brackets whereupon the tightening or loosening of the screw pushes together or allows for the expansion of the two brackets, thereby allowing for a placement or removal of the device on a shelf edge.
There are many other methods and devices for attaching this dispenser to a shelf or wall. Any of them may be used.
Many modifications and variations of the present invention are possible in light of the above teachings. It is, therefore, to be understood within the scope of the appended claims the invention may be protected otherwise than as specifically described.
