Title: Nighttime locatable dispenser

Description:
BACKGROUND  
      Disposable articles, such as facial tissues, are often placed into packaging for storing and dispensing of the articles. For example, facial tissues are often packaged into either an upright or flat carton for dispensing. Many people keep a box of facial tissues located near their bed for use by placing them on a nightstand, a table, or the floor. While placement of the tissue box near the bed is convenient, during the middle of the night, when the room is dark, the tissue box can be hard to locate without the assistance of a light. European patent application EP 1 357 046, filed Apr. 17, 2003 entitled Packaging Wrapper for Hygiene or Wiping Products and herein incorporated by reference, discloses a packaging wrapper having part or parts that exhibit an afterglow in the dark for assistance in locating the product in the dark.  
      However, even if the wrapper is located or observable by glowing in the dark, finding the exact location of the exposed tissue sheet can also be a problem when the tissue must be grabbed quickly to catch a sneeze, cough, or otherwise be rapidly found without fumbling with the box to find the exposed sheet. Another situation where it might be necessary to quickly locate the dispensing opening is for packages containing disposable articles that are used while driving at night. The dispensing opening needs to be quickly located so as not to prolong the driver&#39;s distraction while reaching for the article. Thus, there is a need for a package containing disposable articles that can be readily found in the dark. There is also a need for a package that helps direct a person to the dispensing opening for ease of dispensing the disposable articles in the dark.  
     SUMMARY  
      The inventors have found that the above problems can be overcome by a package having at least a portion that glows in the dark to help a person find the package in the dark. Furthermore, by placing the glow in the dark material at specific locations on the package, the dispensing opening can be highlighted, enabling a person to immediately locate the disposable article.  
      Hence, in one aspect, the invention resides in a product comprising: a package having an exterior and an interior, the interior of the package containing at least one disposable article; a dispensing opening located in the package for withdrawing the disposable article from the interior; and wherein at least a portion of the exterior comprises a glow in the dark material that highlights the location of the dispensing opening.

     DETAILED DESCRIPTION  
      It is to be understood by one of ordinary skill in the art that the present discussion is a description of exemplary embodiments only, and is not intended as limiting the broader aspects of the present invention, which broader aspects are embodied in the exemplary construction.  
      Referring now to  FIG. 1 , a package  20  having an exterior  21  and enclosing an interior is shown. Disposed within the package&#39;s interior is a disposable article  22 . In this embodiment, the package comprises an upright facial tissue carton and the disposable article comprises a plurality of facial tissues. In an upright tissue carton, the facial tissues are formed into an inverted U-shaped stack before being placed into the carton. The package includes a top  24 , a bottom  26 , and a sidewall  28 . In the illustrated embodiment, the sidewall comprises four generally rectangular panels, such as panels  30 , and  32 , that intersect at approximately 90 degree angles. Located in the top is a dispensing opening  34 .  
      The dispensing opening  34  can comprise a simple cutout through the package exterior enabling access to the package&#39;s interior. In other embodiments, the dispensing opening can include additional elements such as a dispensing film  36  having an aperture  38  in the form of an X-shaped cut. In yet another embodiment, the dispensing opening can include a removable cover or surf board that is removed to access the facial tissue. The facial tissues  39  are dispensed through the dispensing opening and can be prevented from falling back into the carton&#39;s interior by the aperture within the film. The package can also have a brand indicator  40  that can be placed on any portion of the exterior. The brand indicator can either identify the manufacturer of the product or represent a trademark linked to the manufacturer of the product. At least a portion of the exterior surface of the package comprises a glow in the dark material.  
      To further enhance the functionality of the package, and in particular to aid in finding the exposed facial tissue residing within the dispensing opening, the placement of the glow in the dark material is optimized. For example, the entire top  24 , exclusive of the dispensing opening and dispensing film, can comprise a glow in the dark material. Thus, the darkened location of the dispensing opening  34  would be easily observable in the top, quickly enabling a person to find the exposed facial tissue in the dark.  
      In another embodiment, the dispensing film  36  can comprise a glow in the dark material to highlight the location of the dispensing opening  34 . The glow in the dark dispensing film can have multiple fingers or petals that would help to find the exposed tissue and could even illuminate portions of the exposed tissue adjacent the film.  
      In another embodiment, the sidewall  28  can comprise a glow in the dark material such that the top and dispensing opening would appear darkened. This also serves to highlight the dispensing opening&#39;s location. Because the top would appear dark relative to the other visible exposed portions of the package, a person could simply move their hand towards the darkened area and grab the exposed tissue.  
      In another embodiment, different portions of the package&#39;s exterior can comprise different colors or contrasting glow in the dark materials to highlight the location of the dispensing opening. For example, the top can comprise one color such as fluorescent green and the sidewall can comprise another color such as fluorescent orange. Alternatively, the dispensing film and top can comprise contrasting glow in the dark materials. In either case, the contrast in color between different portions of the package&#39;s exterior can be used to highlight the dispensing opening or its location.  
      In addition to highlighting the location of the dispensing opening with the glow in the dark material, the brand indicator  40  can comprise a glow in the dark material. Thus, by means of the glowing brand indicator, the package will function similar to a billboard or advertisement when placed into a darkened environment. Illumination of the brand indicator will further strengthen the brand&#39;s recognition with the purchaser and enhance the comfort or satisfaction of the consumer in using that particular brand. In one embodiment, a glow in the dark brand indicator was placed onto each of the four panels comprising the sidewall. Thus, regardless of the package&#39;s orientation relative to the observer, at least one of the glowing brand indicators should be visible in the dark reinforcing the supplier or source of the product.  
      Referring now to  FIG. 2 , another package  20  having an exterior  21  and enclosing an interior is shown. Disposed within the package&#39;s interior is a disposable article. In this embodiment, the package comprises a flat facial tissue carton and the disposable article comprises a plurality of facial tissues. In a flat facial tissue carton, the stack of tissues within the carton is not bent or folded as done in an upright carton. As before, the package includes a top  24 , a bottom  26 , and a sidewall  28 . In the illustrated embodiment, the sidewall  28  comprises four generally rectangular panels, such as panels  30 , and  32 , that intersect at approximately 90 degree angles.  
      Located in the top is a dispensing opening  34 . The dispensing opening can comprise a simple cutout through the package exterior enabling access to the package&#39;s interior. In other embodiments, the dispensing opening can include additional elements such as a dispensing film  36  having an aperture  38  in the form of a slit. In yet another embodiment, the dispensing opening can include a removable cover or surf board that is removed to access the facial tissue. The facial tissues  39  are dispensed through the dispensing opening and can be prevented from falling back into the carton&#39;s interior by the aperture within the film. At least a portion of the exterior surface of the package comprises a glow in the dark or phosphorescent material.  
      To further assist in locating the dispensing opening or the exposed facial tissue, the package can include at least one indicia  42  comprising a glow in the dark material The indicia can be stripes, arrows, straight lines, curved lines, circles, figures, geometric shapes, or other patterns that point towards, surround, or intersect with the dispensing opening.  
      In the illustrated embodiment, the phosphorescent indicia includes a plurality of arrows  44  pointing towards the dispensing opening, a plurality of diagonal lines  46  intersecting with the dispensing opening, and at least one curved line  48  that surrounds the dispensing opening. The arrows, diagonal lines, curved lines, or other indicia can be used either independently or in any desired combination. Because the glow in the dark indicia are used to highlight the location of the dispensing opening, the exposed facial tissue is readily found in the dark.  
      Variations of the illustrated indicia are possible. For example, the location, number, size, and shape of the arrows can be varied. More than one curved line surrounding the dispensing opening can be included forming a figure similar to a bull&#39;s-eye. The curved line can be spaced away from the dispensing opening instead of being immediately adjacent to it. The curved line could be discontinuous or dashed. The location, number, and size of the diagonal lines can be varied.  
      Referring now to  FIG. 3 , another package  20  having an exterior  21  and enclosing an interior is shown. Disposed within the package&#39;s interior is a disposable article. In this embodiment, the package comprises a wet wipes dispenser and the disposable article comprises a plurality of wet wipes. The package includes a top  24 , a bottom  26 , and a sidewall  28 . In the illustrated embodiment, the sidewall comprises four generally rectangular-panels, such as panels  30 , and  32 , that intersect at approximately 90 degree angles.  
      The top of the dispenser is connected to the sidewall with hinges such that the entire top can be opened for refilling the dispenser. Located in the top is a dispensing opening  34 . The dispensing opening comprises a dispensing cover  50 , a flexible dispensing membrane  52  with an aperture  38  and a button  54  for opening the dispensing cover. The dispensing cover is connected to the top with hinges. Upon actuation of the button, the dispensing cover can spring open to reveal the exposed wet wipe (not shown) located beneath the cover. At least a portion of the exterior of the package comprises a glow in the dark material.  
      In one embodiment of the invention, the glow in the dark portion of the package comprises the button, thus pointing out to someone using the package in the dark exactly where to apply pressure to open the dispensing cover for access to the exposed portion of the wet wipe. Highlighting the button with a glow in the dark material highlights the dispensing opening&#39;s location. In another embodiment of the invention, the dispensing cover can be transparent and both the button and the flexible membrane can comprise a glow in the dark material. Thus, after the button is actuated and the dispensing cover springs open, the glowing flexible dispensing membrane would further assist in locating the exposed portion of the wet wipe and the location of the dispensing opening.  
      In another embodiment of the invention, the top, exclusive of the dispensing cover and button, can comprise the glow in the dark material, thereby highlighting the darkened dispensing opening. Alternatively, the top and the dispensing cover can comprise the glow in the dark material and thereby highlight the non-glowing or darkened button. In either case, the contrast between the glowing portions of the package&#39;s exterior and the dark portions will highlight the dispensing opening&#39;s location.  
      In another embodiment of the invention, the glow in the dark portion of the package comprises the dispensing cover to highlight the dispensing opening&#39;s location. By making the cover glow in the dark, a person could conveniently locate the adjacent button, which could have a raised or otherwise textured portion  56 , thus enabling rapidly finding the button even if the button itself did not glow.  
      In another embodiment, different portions of the package&#39;s exterior can comprise different colors or contrasting glow in the dark materials to highlight the location of the dispensing opening. For example, the dispensing cover can comprise one color such as fluorescent green and the button can comprise another color such as fluorescent orange. Alternatively, the top exclusive of the dispensing cover comprise one contrasting glow in the dark material and the button another contrasting glow in the dark material. Any two or more elements such as the top, the dispensing cover, the button, or the dispensing membrane can comprise contrasting glow in the dark materials. In any case, the contrast in color between different portions of the package&#39;s exterior can be used to highlight the dispensing opening or its location.  
      Referring now to  FIG. 4 , another package  20  having an exterior  21  and enclosing an interior is shown. Disposed within the package&#39;s interior is a disposable article  22  (not shown). In this embodiment, the package comprises a dispenser suitable for placement in an automobile cup holder, and the disposable article can comprise either wet wipes or facial tissue. The package includes a removable top  24 , a bottom  26 , and a sidewall  28 . At least a portion of the exterior of the package comprises a glow in the dark material.  
      In the illustrated embodiment, the sidewall is generally circular and comprises a larger diameter upper portion and a smaller diameter lower portion for insertion into a cup holder. Alternatively, the circular sidewall can be straight or tapered for insertion into the cup holder. Alternatively, the maximum dimension of the lower portion of the sidewall can be designed to fit into the cup holder and the remaining portions of the sidewall can be configured in any suitable manner.  
      The dispensing opening  34  is hidden beneath the dispensing cover  50 , which is attached to the removable top by a flexible strap  58 . The dispensing cover also includes a finger tab  60 , which can be used to open the dispensing cover to reveal the dispensing opening and the exposed portion of the wipe or facial tissue.  
      In one embodiment, the location of the dispensing opening is highlighted by applying a circular glow in the dark pressure sensitive label to the dispensing cover. In another embodiment, only the finger tab is highlighted by a glow in the dark material. As with the other embodiments of the invention, contrasting glow in the dark materials or contrasts between the glowing exterior portions and the darkened exterior portions of the package can be used. For example, the dispensing cover, finger tab, and/or strap can be one glow in the dark color or appear darkened if the top glows, and the removable top can be another glow in the dark color or appear darkened if the dispensing cover, finger tab, and/or strap glows.  
      The glow in the dark material can be incorporated to the exterior of the package in a number of ways. For example, in-mold labeling with glow in the dark materials can be used. Glow in the dark pressure sensitive labels can be used. Glow in the dark shrink wrap sleeves or films can be used. Glow in the dark materials forming various portions of the package can be used such as glow in the dark pigments suitable for incorporation into thermoplastics or thermosetting plastics. Glow in the dark inks can be used.  
      The glow in the dark material can glow for a length of time suitable to the intended purpose and have a luminance or brightness suitable for the intended purpose. In one embodiment of the invention, the brightness during the afterglow period can be about 0.32 millicandelas per square meter (mcd/m 2 ) or greater, which is approximately 100 times the limit of human perception in order to ensure that the glowing material was sufficiently visible. In other embodiments of the invention, the brightness of the glow in the dark material can be about 0.6 mcd/m 2  or greater, about 1 mcd/m 2  or greater, about 2 mcd/m 2  or greater, about 10 mcd/m 2  or greater, about 40 mcd/m 2  or greater, between about 0.3 mcd/m 2  to about 2000 mcd/m 2 , or between about 1 mcd/m 2  to about 500 mcd/m 2 .  
      In various embodiments of the invention, the extinction time for the brightness of the afterglow to diminish to less than 0.32 mcd/m 2  at a temperature of 73 degrees Fahrenheit can be about 1 hour or greater, about 3 hours or greater, about 5 hours or greater, about 8 hours or greater, between about 1 hour to about 12 hours, or between about 8 hours to about 10 hours.  
      Longer duration extinction times and higher brightness levels can be used for applications where a person may need to find the dispenser and the dispensing opening&#39;s location in the middle of the night quickly without disturbing someone else who may be sleeping. However, the brightness level should not be too great, which could serve as a distraction while attempting to fall asleep. For this embodiment, in order to ensure that the dispenser remains visible overnight when placed adjacent to the bed, the glow in the dark portions of the package should have a brightness of about 0.32 mcd/m 2  or greater for a duration of about eight hours or greater.  
      Examples of suitable glow in the dark materials include phosphorescent, long after glow phosphorescent, light emitter, or fluorescent substances. The glow in the dark material may be for example a polycrystalline inorganic zinc sulphide which can create a green illumination or an alkaline earth sulphide which can create a red or blue illumination. In general, there are two categories of phophors: zinc sulfide and oxides of strontium aluminate that are suitable glow in the dark materials, with the zinc sulfide having a shorter extinction time as compared to the longer lived strontium aluminate.  
      The glow in the dark material may be a SAFE-GLO or SPARKLE-GLO film available from Coburn Corporation in New Jersey. SAFE-GLO film comprises a rigid PVC copolymer with an incorporated second surface of an inorganic zinc sulfide phosphor. SPARKLE-GLO has transparent polyester particles harmoniously dispersed within the second surface and is offered in four different color hues.  
      Suitable glow in the dark materials are available from LUNA Technologies International in Kent, Wash., who are makers of high performance photoluminescent lighting, coatings, compounds, films and paints. LUNAPLAST long afterglow photoluminescent pigment, available from LUNA Technologies, can be used for the glow in the dark material.  
      Suitable glow in the dark materials are available from Nemoto &amp; Co. Ltd, Tokyo, Japan, makers of phosphorescent and fluorescent pigments. LUMINOVA is a suitable glow in the dark material based on strontium aluminate and is disclosed in U.S. Pat. No. 5,424,006 entitled Phosphorescent Phosphor issued on Jun. 13, 1995, to Murayama et al., and herein incorporated by reference.  
      Suitable glow in the dark materials are available from Honeywell Specialty Chemicals Seelze GmbH, Seelze, Germany. Honeywell Specialty Chemicals makes several LUMILUX branded glow in the dark materials, including LUMILUX SN and N pigments that qualify as long afterglowing products according to DIN 67510 part 4 that are suitable for the glow in the dark material.
