CROSS REFERENCE TO RELATED APPLICATIONThis application is a divisional application of U.S. patent application Ser. No. 10/424,655, filed Apr. 28, 2003, which is incorporated herein by reference.
BACKGROUNDCurrently, disposable absorbent pant products, such as training pants, are displayed in the diaper aisle of a retail store and are typically packaged in bulk conventional packages containing from about 15 to about 100 products. The disposable absorbent pant products are generally stacked within the conventional package in either one or two stacks similar to how diapers are packaged. The packages generally sit on the store shelf and cannot be hung from other merchandising apparatus.
The use of disposable absorbent pant products is a next logical step in the toilet training process after diapers, but prior to regular reusable underwear. Caregivers frequently transition directly from diapers to reusable underwear for their toddler. One reason is that caregivers are overly optimistic that training will go quickly and smoothly, or do not recognize that specifically designed training pants will promote an easier transition by more readily accommodating accidents than reusable underwear.
Thus, what is lacking and needed in the art is a method for displaying or merchandising disposable absorbent pant products in a retail store with reusable clothing to encourage or remind caregivers that training pants can be used after diapers and before reusable underwear to promote the toilet training process, as well as a package for disposable absorbent pant products.
SUMMARYIn response to the above-referenced unfulfilled need in the art, a new method for displaying such disposable absorbent pant products and a new package for disposable absorbent pant products have been invented.
One aspect of the invention pertains to a method for displaying disposable absorbent pant products in a retail store. The method includes displaying clothing in the store, and displaying a package of disposable absorbent pant products in the store in the same region in which the clothing is displayed. Such packages can include from 1 to about 5 disposable absorbent pant products, to provide a cost effective vehicle for caregivers to try training pants, and thereby realize the benefits they can bring to the toilet training process.
Another aspect of the invention pertains to a package containing at least one disposable absorbent pant product. The package includes a pocket and can also include a display window through which consumers may view the disposable absorbent pant product inside the package. The package is similar to packages currently used for reusable underwear. The package also includes a device for hanging the package in a retail store, such as for example, an aperture in a flap attached to the pocket through which the package may be hung on a hook, or a small hanger, or any other hanging or displaying means known in the art. The pocket may be reclosable to allow the package to be used as a waste container to hold soiled pants.
One of the benefits provided by the method and package of the invention is an increased perception of the disposable absorbent pant product being more “underwear-like” than a diaper. This increased perception benefits not only the user, but also the caretaker. Another benefit provided by the method and package of the invention is greater ease for consumers to try the disposable absorbent pant products without the necessity of purchasing a conventional package containing a larger number of the products. Another benefit applies to consumers who use disposable absorbent pant products for overnight use and/or other incontinence use. The package of disposable absorbent pant products of the invention marketed discreetly in the durable goods section of a store helps to preserve the modesty and privacy of these consumers, i.e., a discretion benefit. Furthermore, the ability to try disposable absorbent pant products (without a big purchase commitment for a larger sized package) can allow consumers to experiment with different routes toward toilet training with the greatest ease. Such experimenting with different routes toward toilet training can be beneficial because children differ in their abilities and will train at various rates, using a variety of methods, depending on each child's capabilities and preferences at the time.

DETAILED DESCRIPTIONReferring toFIG. 1, there is illustrated a disposableabsorbent pant product10, or disposable training pant. The disposableabsorbent pant product10 includes afront panel12, aback panel14, acrotch panel16 interconnecting front andback panels12 and14, and a pair ofelastic side panels18. Eachelastic side panel18 is formed from two separate elastic portions and are suitably joined together, such as by ultrasonic bonding, to form aside seam20. Theside panels18 can be partially or fully integral with the front andback panels12 and14. Upon construction of the side seams20, awaist opening22 andleg openings24 are formed. The side seams20 may be constructed to be manually tearable in order to allow the disposableabsorbent pant product10 to be disassembled manually by the caregiver, so that it can be easily removed from the child after a bowel movement. A more detailed description of the construction and design of the above-described disposableabsorbent pant product10 can be found in U.S. Pat. No. 4,940,464, herein incorporated by reference. The manufacture of training pants can be accomplished in the manner described in U.S. patent application Ser. No. 09/855,484, filed 15 May 2001 (U.S. Publication US 2002/0000291, Jan. 3, 2002) by Joseph D. Coenen et al., which is incorporated herein by reference. One specific manner of supplyingelastic side panels18 is described in U.S. Pat. No. 5,224,405 and in U.S. Pat. No. 5,104,116, both of which are incorporated herein by reference. The provision of side seams20 can be accomplished in the manner described in U.S. Pat. No. 5,046,272, herein incorporated by reference. The side seams20 can be permanent seams or refastenable seams.
The disposableabsorbent pant product10 can have multiple appearance-related and/or function-related components. Examples of components that are appearance-related include, but are not limited to, graphics; the highlighting or emphasizing of leg and waist openings in order to make product shaping more evident or visible; the highlighting or emphasizing of areas in the article to simulate functional components such as elastic leg bands, elastic waistbands, simulated “fly openings” for boys, or ruffles for girls; the highlighting of areas of the product to change the appearance of the size of the product; selectively positioned wetness indicators; back labels or front labels; and selectively positioned written instructions at a desired location on the article.
Examples of function-related components include, but are not limited to, waist elastics, leg elastics, areas of breathability, fluid repellent areas, fluid wettable areas, adhesives, coatings, encapsulated inks, chemically-sensitive materials, environmentally-sensitive materials, heat-sensitive materials, moisture-sensitive materials, perfumes, odor control agents, inks, fasteners, fluid storage areas, textured or embossed areas, or the like.
The disposableabsorbent pant product10 can further comprise a front waist elastic26, suitably joined tofront panel12, a back waist elastic28 suitably joined to backpanel14, leg elastics30 suitably positioned incrotch panel16, and anabsorbent pad32 positioned between a liquid impermeable outer cover or backsheet34 and a liquid permeable liner ortopsheet36. Theabsorbent pad32, positioned between thebacksheet34 and thetopsheet36, can be any structure which is generally compressible, conformable, non-irritating to the skin, and capable of absorbing and retaining liquids and certain body wastes. Theabsorbent pad32 can be manufactured in a wide variety of sizes and shapes, and from a wide variety of liquid absorbent materials commonly used in the art. For example, theabsorbent pad32 can suitably include a matrix of hydrophilic fibers, such as a web of cellulosic fluff, and the cellulosic fluff may be mixed with particles of a high-absorbency material commonly known as superabsorbent material. In a particular embodiment, theabsorbent pad32 includes a matrix of cellulosic fluff, such as wood pulp fluff, and synthetic fibers, such as coform or airlaid materials. The wood pulp fluff can be exchanged with synthetic, polymeric, meltblown fibers or with a combination of meltblown fibers and natural fibers. The superabsorbent particles can be substantially homogeneously mixed with the hydrophilic fibers or can be nonuniformly mixed. The fluff and superabsorbent particles can also be selectively placed into desired zones of theabsorbent pad32 to better contain and absorb body exudates. The concentration of the superabsorbent particles can also vary through the thickness of theabsorbent pad32. Alternatively, theabsorbent pad32 can include a laminate of fibrous webs and superabsorbent material or other suitable means of maintaining a superabsorbent material in a localized area.
Suitable superabsorbent materials can be selected from natural, synthetic, and modified natural polymers and materials. The superabsorbent materials can be inorganic materials, such as silica gels, or organic compounds, such as crosslinked polymers. Suitable superabsorbent materials are available from various commercial vendors, such as Dow Chemical Company located in Midland, Mich., U.S.A., and Stockhausen GmbH & Co. KG, D-47805 Krefeld, Federal Republic of Germany. Typically, a superabsorbent material is capable of absorbing at least about 15 times its weight in water, and desirably is capable of absorbing more than about 25 times its weight in water.
In one embodiment, theabsorbent pad32 is generally rectangular in shape, and includes a blend of wood pulp fluff and superabsorbent material. One type of fluff is identified with the trade designation CR1654, available from U.S. Alliance, Childersberg, Alabama, U.S.A., and is a bleached, highly absorbent sulfate wood pulp containing primarily soft wood fibers. As a general rule, the superabsorbent material is present in theabsorbent pad32 in an amount of from about 0 to about 90 weight percent based on total weight of theabsorbent pad32. Theabsorbent pad32 suitably has a density within the range of about 0.10 to about 0.35 grams per cubic centimeter. Theabsorbent pad32 may or may not be wrapped or encompassed by a suitable tissue wrap that maintains the integrity and/or shape of theabsorbent pad32.
A graphic38 can be selectively positioned onfront panel12, and as illustrated includes a design of a simulated “fly opening”40, typical of a male's underwear, along with a rainbow, sun, clouds, and cars. The graphic38 can be any type of desired pattern, artistic feature, or the like, and is desired to be positioned in the article at a selected location. The graphic38 can also include, for example, simulated waist ruffles and/or, simulated leg ruffles (not shown). Again any suitable graphic can be utilized so as to convey an aesthetically and/or functionally pleasing appearance to the user and caregiver.
As representatively illustrated inFIGS. 2-5, an embodiment of apackage50 of the present invention includes apocket54. Thepackage50 can include a flap ortab52 attached to thepocket54. Thepocket54 includes anouter surface56, aninner surface58, afront surface60 and a back surface66 (FIG. 4) opposite thefront surface60. Thepackage50 has a generally rectangular shape, but can be any desired shape. The length of theflap52 is generally less than one-third of the length of theentire package50 as shown, but can be any desired length. The width of theflap52 can be greater than, equal to, or less than the width of thepocket54.
Thepackage50 further includes a disposableabsorbent pant product10, such as for example, a training pant or the like, on the inside of thepocket54. The pocket can include adisplay window62 disposed or positioned within a portion of thefront surface60 of thepackage50.Display window62 includes awindow periphery64 that has a shape that is substantially semi-circular, but any desired shape is contemplated.Display window62 at least substantially frames a component of the disposableabsorbent pant product10. InFIGS. 2-3 and5, the component framed bydisplay window62 is a portion or segment of graphic38, which is visually perceivable throughdisplay window62.
Thepocket54 can contain at least one disposableabsorbent pant product10, desirably up to five disposableabsorbent pant products10, but desirably not more than ten disposableabsorbent pant products10. The graphic38 of the disposableabsorbent pant product10 can be selectively positioned on the disposableabsorbent pant product10, and the disposableabsorbent pant product10 can be selectively positioned in thepocket54 so that the graphic38 shows at least partially through thedisplay window62. The graphic38, as illustrated inFIGS. 2-3 and5, can be a cat illustration, or any other design as previously mentioned.
As shown inFIG. 2 each of the disposableabsorbent pant products10 can be disposed inside thepocket54 in a flat configuration stacked one on top of another in a manner such as that described in U.S. Pat. No. 6,318,555 issued Nov. 20, 2001 to Kuske et al., herein incorporated by reference. As an alternative, as shown inFIGS. 3 and 4 each of the disposableabsorbent pant products10 can be disposed inside thepocket54 in a rolled configuration by rolling the disposableabsorbent pant product10 from thecrotch panel16 in the direction of arrow70 (FIG. 1) upward toward the back waist elastic28. As another alternative, as shown inFIGS. 5 and 6, each of the disposableabsorbent pant products10 can be disposed inside the pocket in a folded and staggered configuration in a manner similar to how reusable underwear is folded by folding theside panels18 in the direction of arrows72 (FIG. 1) and by also folding thecrotch panel16 back towards theback panel14 and then staggering the disposableabsorbent pant products10 as shown. It is contemplated that the disposableabsorbent pant product10 can be in any folded or other configuration known within the art in thepocket54.
In particular embodiments, thepocket54 including the disposableabsorbent pant products10 can be sealed so as to provide a sanitary environment inside thepocket54 for the disposableabsorbent pant products10. Thepocket54 can be heat sealed, adhesively-sealed, or sealed by any sealing method known in the art.
Referring to displaywindow62 framing a component, such as graphic38, the terms “framing,” “substantially framing,” or variations thereof, mean that thewindow periphery64 surrounds or encompasses all or at least a portion of the component for visual display. Within the context of this description, a component is visually perceivable if the portion of thedisplay window62 over the component is clear or substantially clear to the person viewing it. The term “clear” refers to the material's capability of transmitting light so that the component, or a portion thereof, can be seen as clearly as if there were no intervening material between the component and the individual. The term “substantially clear” refers to the capability of transmitting light, but causing sufficient diffusion of the light to eliminate perception of distinct images, shapes, forms or the like.
Thedisplay window62 can cover either all or a portion of thefront surface60 of thepocket54 of thepackage50. In particular embodiments, thedisplay window62 covers at least 10%, but not more than 90% of thefront surface60 of thepackage50.
The present invention thus provides the feature of permitting a user, a caregiver, or the like, to visually see or perceive a component, or a portion thereof, of the article they are purchasing. The purchaser may also be able to see or determine the size of the article, thereby providing a degree of confidence in proper fit. This provides product visibility at the time of purchase to the user and the caregiver. For example, when thepackage50 contains a training pant, a child can see the gender-specific graphic, as well as the specific product being selected. This provides the child with a sense of ownership and an active role in the toilet training process. This encourages the child to become toilet trained. In addition, the increased perception of the disposable absorbent pant product being more “underwear-like” than a diaper also helps to encourage the child to become toilet trained. The caregiver can also see a desirable feature or component of the product. For example, if a training pant has a unique outer cover that is, for example, both cloth-like in texture and includes a unique design or graphic, then the caregiver can have a high degree of confidence in the appropriateness of the product being selected for purchase.
In manufacturing packages, such aspackage50, for containing, for example, disposableabsorbent pant products10, it is customary to print the package material, either on its outermost surface or its innermost surface, with a color, illustrations, written instructions, source of manufacture, or the like. In this description, the term “background” or variations thereof refers to the surrounding, primarily discernible or perceivable color ink image printed on thepackage50. For example, if disposableabsorbent pant products10 are manufactured as gender-specific pants, such as training pants, then thepackage50 can have a background color of blue for boys, and pink for girls. In this case, the surrounding, primarily perceivable or discernible color would be blue or pink in areas other than in thedisplay window62. The term “copy” refers to written indicia, numbers, letters, symbols, artistic images or patterns, or the like. Generally, copy is either printed over the background, or over areas of thepackage50 not printed with background.
Referring toFIGS. 2-5,package50 includes copy to indicate the product as training pants, weight range (i.e., 32-40 lb, 15-18 kg), size range (i.e., 3T-4T), and the number of items in the package (i.e., 3).
Desirably, thepackage50 includes a device for hanging thepackage50 for sale in a retail store. Such device can include, for example, a flap ortab52 with anaperture80. Theaperture80 can be adapted to fit over a J-hook so that thepackage50 can hang vertically from the J-hook for display on the display rack or shelf. It is also contemplated that the device for hanging thepackage50 can include small hangers attached to thepocket54 or to theflap52. Other examples of devices for hanging include, for example, an aperture in the pocket, hook or loop fastener material on thepackage50 which will attach to corresponding loop or hook fastener material on a display shelf or wall, or a flap or tab adapted to be hung or secured by a clip located on a display shelf or wall, or other hanging apparatus or means known in the art.
In addition, it is also contemplated that thepocket54 can include areclosable feature82, such as for example, a zip-type seal. One example of such a reclosable feature is the ZIPLOC® food storage plastic bag manufactured by the Dow Chemical Company, Midland, Mich., U.S.A. Thereclosable feature82 will also enable the caregiver to use thepocket54 as a receptacle for soiled disposable absorbent pant products. Alternatively, thereclosable feature82 can include buttons, snaps, hook and loop fastening components, or any other reclosable devices known in the art. It is contemplated that thepocket54 can include thisreclosable feature82 in addition to being sealed to provide a sanitary environment as discussed above.
Thepackage50 may be composed of different materials, or may be composed of substantially a single type of material. Typically, the material may be a polymer film which is flexible for accommodating the desired number of disposableabsorbent pant products10. In addition, the material should have sufficient strength to hold and contain the disposableabsorbent pant products10 without breaking and without excessive bulging or stretching of the film material. For example, the film material may be composed of a polyethylene film or film laminate having a thickness of about 2.5 mils (about 0.0635 millimeters). Other examples include a LDPE (low density polyethylene) film, a LDPE/LLDPE (linear low density polyethylene) film laminate, a LDPE/MDPE (medium density polyethylene) film laminate, a LDPE/HDPE (high density polyethylene) film laminate or the like.
Thepackage50 can also include other items, such as an interactivity device and/or an activity device.
Interactivity devices and activity devices are described, for example, in U.S. Pat. No. 5,725,382 issued to Walter et al. on Mar. 10, 1998, herein incorporated by reference. Interactivity devices can serve to encourage and motivate the wearer to begin and successfully progress through the toilet training process and also to promote interaction between the caregiver and the wearer. In order to promote interaction between the caregiver and the wearer, interactivity devices to be used by the caregiver and wearer for instructing and aiding in toilet training can be included in thepackage50. Typical examples of interactivity devices include, but are not limited to, a two-dimensional learning graphic illustrating a child using the toilet properly, a two-dimensional learning graphic illustrating a child pulling up or pulling down a training pant properly; educational materials; informational materials; flash cards; reward items; videotapes; or the like. These examples are typical of an interactivity device that creates the appropriate interaction between a caregiver and the wearer. For example, a graphic illustrating a child using the toilet properly can be used by the caregiver to explain to the child how he or she can use the toilet in the same manner. Similarly, other two-dimensional learning graphics, flash cards, stickers and an associated progress chart, educational or informational materials, or the like can be used by the caregiver to encourage and motivate the wearer in toilet training. These interactivity devices can be linked or associated together with common graphics or characters to reinforce the learning process in toilet training. This positive interaction between the caregiver and the wearer, which creates an encouraging and motivational atmosphere for the wearer, encourages the wearer to progress through the toilet training process easily and quickly.
Another feature of the present invention, in addition to the interactivity devices described above, are activity devices to be used by the child in toilet training. These activity devices are intended to be used independently by the child to encourage and motivate the child through the toilet training process. For example, the activity devices can acquaint and educate the child to toilet training, provide the motivation for the child to desire to toilet train, create a sense of ownership and independence in the child that encourages the child to progress through toilet training, or the like. Examples of these activity devices include, but are not limited to, crayons, a graphic to be colored, colored pre-printed graphics, urine targets, or the like.
Thepackage50 can also include purchase incentive items. Such purchase incentive items can include the interactivity devices and activity devices described above, or other items such as coupons.
The present invention is also directed to a method for displaying disposableabsorbent pant products10 for sale in a retail store. Within a retail store, disposable goods are generally separated from durable goods (i.e., non-disposable). Usually, separate buying units are responsible for purchasing the disposable goods and durable goods for the retail store. In addition, the purchase dynamics on the part of the consumers are often significantly different. Disposable products may be purchased in bulk on a more frequent (e.g. weekly) basis than durable goods. However, durable goods may be purchased in smaller numbers less frequently (e.g. every month or two, or longer.)
As illustrated schematically inFIG. 7, aretail store200 can include different regions for displaying different categories of products. Theretail store200 can include afirst region202. Thefirst region202 can includedisplay units204. Thedisplay units204 can, for example, be shelves, partitions, racks, or any other appropriate unit for displaying products. Thedisplay unit204 can defineaisles206 through which consumers can walk and from which consumers can see and access thedisplay units204. Thefirst region202, for example, can be the region of theretail store200 havingdisplay units204 displaying diapers, training pants, or other disposable absorbent pant products, wipes and other disposable absorbent products for infants, toddlers, and adults, and related items. Theretail store200 can also include asecond region220 spatially separated from thefirst region202 in theretail store200. Thesecond region220 can also havedisplay units204, andaisles206. Thesecond region220, for example, can be the region of theretail store200 havingdisplay units204 displaying clothing and regular reusable or durable (i.e., launderable) underwear. It is contemplated that some retail stores (e.g. some department stores) will sell clothing such as reusable or durable underwear but not sell disposable products, in which case they will be considered for purposes of the present invention to have one region but not first and second regions as those terms are used herein.
According to the invention, a previously described disposableabsorbent pant product10 is placed into the previously describedpackage50. The disposableabsorbent pant product10 can be a training pant. Desirably, thepackage50 is generally the same size and shape as packages of reusable underwear, for example children's reusable underwear. Clothing is displayed in thesecond region220 of theretail store200. The clothing can be reusable children's clothing. Thepackage50 is then displayed in theretail store200 in thesecond region220 of theretail store200. Conventional packages of disposable absorbent pant products and/or packages of diapers may also be displayed in theretail store200 in thefirst region202. In those retail stores that do not sell disposable products, thepackage50 can be displayed in the region of the store that also displays clothing.
In an alternative embodiment, the method of the invention includes displaying reusable clothing in theretail store200 and hanging apackage50 of disposableabsorbent pant products10 in the region of theretail store200 displaying the reusable clothing. Thepackage50 of disposableabsorbent pant products10 is hung in the same aisle as and in visual proximity to a hanging package of reusable children's underwear.
