1. Field of the Invention

The present invention discloses a method for dispensing scented coupons in a way that activates the scents as they are removed from a coupon dispenser.

2. Description of the Prior Art

Over the years, there have been many dispenser boxes developed for the dispensing of sheets of paper or coupons of some sort. This type of device has become more important in the market place as grocery and other stores have installed coupon dispensers on their shelves to give consumers incentives to make impulse purchases based on lower prices given at their stores on any given day of the week.

To accommodate consumer needs, there has been a number of different paper dispensing devices over the years.

U.S. Pat. No. 2,253,742 (W. H. West et al.) discloses a dispenser for interfolded paper. The dispenser comprises a vertically disposed container having a dispensing opening and a spring-actuated follower plate in the container adapted to support a vertically disposed stack of interfolded paper sheets. A plate is secured to the under side of the cover at one side of the dispensing opening, and engages the upper end of the stack while maintaining a predetermined spacing between the stack and the dispensing opening. A second plate is secured to the underside of the cover, the ends of the plates adjacent the dispensing opening being rounded to form deflecting surfaces.

U.S. Pat. No. 5,390,820 (Wright et al.) discloses an elevating dispensing device for flexible sheet material. The dispensing aperture has flaps to retain the end of successively drawn sheets above the aperture for ease of withdrawal. The stack of sheets rests within the carton on an elevating platform which is flexibly attached on two opposing sides to the base of the adjacent side walls of the carton by flexibly folded extension panels which allow upward urging of the elevating platform.

U.S. Pat. No. 2,237,424 (S. N. Hope) discloses a sheet dispenser comprising a casing adapted to contain a pack of interfolded sheets and having opposite end walls with inwardly directed embossments adjacent to the opposite sides of the casing. A pair of cover members extend between the casing end walls and having end walls with outwardly directed embossments adapted to register with the casing embossments. A coiled spring for each cover member urges the cover member against the pack, with the spring surrounding a cooperating pair of the embossments on the casing and cover member.

U.S. Pat. Nos. 4,993,590 (Windorski), and U.S. Pat. No. 5,165,570 (Windorski et al.) are for dispensers for a stack of partially adhesive coated sheets stacked with the adhesive coating on each successive sheet disposed along alternate opposite sides of the stack and releasably adhering the sheets together.

In U.S. Pat. No. 4,993,590, the dispenser for adhesive coated sheets has opposed end surfaces having parallel upper ends adapted to be engaged by the opposite sides of the stack with the with the top sheets in the stack parallel to the adjacent upper ends, with the opposed end surfaces diverging slightly from each other toward the upper ends of the end surfaces to cause movement of the end portions of the stack along the end surfaces toward the upper ends in response to forces applied to the stack to sequentially remove sheets from the stack through the opening.

U.S. Pat. No. 4,993,590 (Simpson, assigned to Comakr Bates) discloses a dispenser box allowing for the removal of individual coupons without the chance of another coupon being removed at the same time. The dispenser comprises walls defining a cavity adapted to receive the stack of sheets, a rectangular flat top wall having an opening through which the sheets may be individually dispensed, a flat bottom wall having approximately the same dimensions as the flat top wall, with the flat bottom wall being approximately parallel to the flat top wall, and resilient means to push the stack of said sheets to the opening in the top wall of the dispenser.

The present invention discloses a method for dispensing scented coupons in a way that activates the scents as they are removed from a coupon dispenser. Specifically, the dispenser allows scented coupons or pieces of paper to be individually removed without the chance of another coupon being removed at the same time. The scented coupons have a perfume, cologne, or other fragrance, in a slurry, which is preferably encapsulated along the edges of a fold in the coupon.

Microencapsulation is a process to enclose very small-sized core materials, either solids or liquids, in the coating materials. This technique has played a significant role in a variety of industries for many years. These include pharmaceutical, cosmetic, food, agricultural, plastic, paper, photographic, printing, paint, adhesive and computer industries.

Microencapsulation is a process in which very thin coatings of inert natural or synthetic polymeric materials are deposited around microsized particles of solids or droplets of liquids. Products thus formed are known as microcapsules.

Microcapsules consist of two major parts. The inner part is the core material comprised of one or more active ingredients. These active ingredients may be solids, liquids, or gases. The outer part is the coating material which is usually a high molecular weight polymer or a combination of such polymers. The coating material can be chosen from a wide variety of natural and synthetic polymers. The coating material must be nonreactive to the core material, preferably biodegradable, and nontoxic. Other components, such as plasticizers and surfactants, may also be added to microcapsules.

The unique feature of microcapsules is the diminutive size of the coated particle the particle size usually ranges from several nanometers to several micrometers. Particles between 1 and 2000 micrometers in diameter are called microcapsules, whereas the products with the diameter smaller than 1 micrometer are referred to as nanocapsules. Various types of physical structures of the product of microencapsulation such as mononuclear spheres, multinuclear spheres, and multinuclear irregular particles, can be obtained depending on the manufacturing process. The most common structure formed is the mononuclear sphere.

The encapsulation of a fragrance protects the core materials against atmospheric deterioration. There is an enhancement of stability of the core materials.

The coupons themselves are folded and preferably have a mild adhesive. As the coupon is removed from the dispenser, the slurry or microencapsulation is broken, and the scent is released.

The dispenser is placed in a supermarket, on a shelf, where consumers would remove coupons to get discounts on particular grocery products when they go to the cashier's counter. The scent, could have the aroma of perfume, pizza, chocolate, or any other enticing smell which would entice the shopper to purchase the product in question.

In the proposed invention, there is no "divergence" of any possible equivalent end surfaces. The surfaces of the proposed invention are all either perpendicular or parallel to each other, except for the semi-circular piece of styrene that keeps pressure on the coupons so that they stay up against the opening of the box for easy withdrawal from the dispenser. In one embodiment of the invention, the inside of the dispenser is a triangular shape that assists the semi-circular piece of styrene in keeping an upward pressure on the coupons which helps the coupons "sit up" in the dispenser box to allow them to be easily pulled out by a folded edge of the coupon.

In another one embodiment of the invention, the design of the dispenser allows it to be printed, die-cut and folded out of one piece of paper stock.

In yet another embodiment of the invention, the dispenser contains a header piece for hanging on the store shelf and for adding graphics. This header piece can be located on several other panels of the dispenser box.

In another embodiment of the invention, the dispenser may be part of an in-store display. The dispenser may also be part of an in-store easel.

FIG. 1 is a perspective view of the coupon dispenser;

FIG. 2 is a cross-sectional view of the coupon dispenser;

FIG. 3 is a perspective view of one of the coupons;

FIG. 4 is a cross-sectional view of the coupon dispenser; and

FIG. 5 is a side view of one of the scented coupons.

Referring to FIGS. 1-5, the dispenser 1 comprises a top section 2 having an opening 3 through which the scented coupons ons or flexible sheets 4 may be dispensed. The dispenser has a stack of scented coupons 4 disposed one on top of another and folded at a specific length, allowing for the dispensing of individual scented coupons 4.

The scented coupons 4 are folded at an edge 30, thereby creating a bottom sheet 31 integrally and continuously connected along the folded edge 30 to a top flap 32. Between the bottom sheet 31 and the top flap 32 is the microencapsulated scent 33. This scent may be along a specific strip 34, or the microencapsulated scent may be evenly distributed over the surface area covered by the top flap 32. On top of or around the miscroencapsulated scent is a light adhesive 37. This light adhesive allows the top flap 32 and the bottom sheet 31 to be held together until it is removed from the dispenser 1 by means of the flap 32. A front "tab" section 35 of the flap 32 preferably has no adhesive on its underside, thereby allowing the user of the dispenser to pull the tab 35 to remove the scented coupon 4 from the dispenser 1. As the scented coupon 4 is removed from the dispenser 1, the top flap 32 is pulled from the bottom sheet 31. This pulling action separates the adhered flap 32 and sheet 31, and further breaks the microcapsules 36 holding the scent as the adhesive "tugs" on the microcapsules 36, thereby releasing the scent.

The walls of the dispenser define a cavity 5 adapted to receive the stack of scented coupons 4. The dispenser 1 is generally rectangular or box shaped, having a large enough interior area to store a number of scented sheets or coupons 4. A rectangular flat top wall 3 has an opening 3 through which the scented coupons 4 may be individually dispensed.

The dispenser 1 has two short flat end walls 6. Edges 7 of these short flat end walls 6 are positioned perpendicularly to edges 8 of the width of the flat top wall 2 at opposite ends of the flat top wall 2. The two short flat end walls 6 are parallel to each other, with each of the two short flat end walls 6 having the same dimensions as the other flat end wall.

Between the two short flat end walls 6 are two long flat side walls 9. The edges 10 of each of the two long flat side walls 9 are positioned along the edges of the length 11 of the top wall 2 with the long flat side walls 9 positioned perpendicularly to the flat top wall 2. Each of the long side walls 9 are located on opposite sides of the width of the top wall 2, such that the two long side walls 9 are parallel to each other.

The dispenser 1 also has a flat bottom wall 12 having approximately the same dimensions as the flat top wall 2, without an opening. The flat bottom wall 12 is approximately parallel to the flat top wall 2, wherein one edge 13 along the length of the flat bottom wall is affixed to the bottom of the dispenser 1. The stack of scented coupons 14 is positioned between the two short end walls 6.

In a preferred embodiment of the invention, a resilient means is used to push the stack of scented coupons 14 up to the opening 3 in the top wall 2 of the dispenser 1. In one embodiment of the invention, the means to push the scented coupons to the opening of the dispenser is an arc type structure 15 positioned underneath the stack of scented coupons 14. This arc type structure 15 is positioned between the short end walls 6 and above the flat bottom wall 12. The peak of the arc type structure 15 is in communication with the stack of scented coupons 14, pushing the stack of scented coupons 14 towards the opening 3 in the dispenser 1. In another embodiment of the invention, the arc type structure 15 may be flexed and inserted between the stack of scented coupons 14 and the bottom wall 12.

Another preferred feature of the dispenser directs the stack of scented coupons towards the opening in the top wall of the dispenser. More preferably, this feature is an angular formation 16 positioned between one of the end walls 6 and the top wall 2, to direct the stack of scented coupons 14 towards the opening 3 in the top wall 2 of the dispenser 1. Preferably, this angular formation 16 is a triangular shaped piece 16 positioned between the end wall 6 and the top wall 2. This triangular shaped piece is most preferably in the form of a right trangle which fits into one of the top corners of the dispenser 1. In a more preferable embodiment of the invention, the angular formation 16 is the material from opening 3 folded back toward wall 6.

The exterior walls of the dispenser 1 may be made out of one unitary piece of material wherein the material is selected from the group consisting of paper, styrene, and plastic. In line with this arrangement, it is a preferred embodiment to have flaps or tongues 17 on one edge of each wall so that the unitary piece of material may be folded into the box like dispenser. In such an arrangement, the bottom wall of the device may be secured in place to an overlapping flap or tongue by means of an adhesive of some sort such as tape or glue. In yet another embodiment of the invention, the box may have slits 17 into which the flaps or tongues are inserted to hold the dispenser 1 in its box-like shape.

The dispenser may also have a header 18 for displaying the dispenser 1. This header 18 may be positioned along virtually any wall or edge of the dispenser 1 but it is most preferable to have the header positioned along the same plane as that of the bottom section 12, to allow for the display of the dispenser 1.

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.
