DETAILED DESCRIPTION

FIG. 1 shows an isometric view of one exemplary embodiment of the present invention. Dispenser 10 includes housing 14, a substantially transparent cover 12, and an article bearing a multi-dimensional image 13. The cover contains a first aperture adapted for dispensing an item in a pad of material, such as repositionable note 16 in a pad of material. Exemplary pad of material include, but is not limited to, repositionable notes such as Post-it® pop-up notes, repositionable flags such as the Post-it® flags, and precut tape, such as pop-up tape, all commercially available from 3M Company, St. Paul, Minn.
FIG. 2 is a cross-sectional view of the dispenser of FIG. 1. Housing 14 is polygonal and is similar in shape to that of pad of material 17. The housing has a base and four upright walls extending from the base. The housing includes cavity 19 adapted for receiving the pad of material. The housing further includes spring 18 serving as a means for biasing the pad of material against the cover thereby allowing for continual dispensing of the pad of material until the entire pad is consumed. This particular dispenser is particularly suited for a pad of material that is assembled in a z-stack format, i.e., where the repositionable adhesive of a first item in the pad is disposed at the opposite edge of the repositionable adhesive of the next subsequent item in the pad. The figure shows repositionable note 16 exposing from and to the right hand side of the dispenser. In the z-stacked configuration, when a user pulls on the exposed note, the next available note will be dispensed to the left hand side of the dispenser. The housing further includes post 20. As best shown in FIG. 1, four posts are used in this embodiment, each post residing approximately in the corner of the housing.
Cover 12 has opposing inner and outer surfaces, 12 a and 12 b, respectively. The cover includes first aperture 21 adapted for dispensing a pad of material and second aperture for mating with posts 20 in the housing. The second apertures are aligned with the posts of the housing. This particular design allows the cover to be attached and detached from the housing when a new pad of material needs to be loaded into the dispenser. The posts provide an interference fit with second apertures in the cover. If desired, the outer surface of the cover may include indicia, such as those used in the promotional market for advertising.
Dispensers that can be used in the present invention include but are not limited to those disclosed in U.S. Pat. Nos. 4,796,781; 4,921,127; 4,986,440; 4,993,590; 5,080,255; 5,167,346; 5,671,866, and 6,068,138. While these dispenser patents recited may not disclose that the cover is transparent, one can practice the invention by substituting a transparent cover.
FIG. 3 shows one exemplary article 30 bearing a multi-dimensional image. The article is of multilayer construction and includes a substantially transparent lenticular film 32. The lenticular film has first structured surface 32 a and opposing second substantially flat surface 32 b. Base sheet 36 includes first surface 36 a containing an image (not shown) and opposing second surface 36 b. Adhesive 34 attaches the lenticular film to the base sheet. Any adhesive can be used in the present invention, so long as it does not interfere with the visual appearance of the article. In one embodiment, the adhesive is substantially transparent. In this particular construction, the image disposed on surface 36 a of the base sheet is buried and thus protected.
While the article in FIG. 3 shows a multi-layer construction, it is within the scope of the present invention to have the image disposed directly on the second, substantially flat side 32 b of the lenticular film. If desired, a white ink can be printed directly over the image covering substantially all of the second side of the lenticular film. Whether a single or multi-layer construction is used, the image can be formed using any of a variety of printing techniques, including but not limited to inkjet printing, and other printing techniques, such as, but not limited to, silk screening, offset printing, and flexo-printing.
FIG. 4 shows a top plan view of an exemplary article bearing a multi-dimensional image. In this particular case, for ease of understanding, the lenticular portion of the article has been removed. Article 40 includes images 41, first opening 43 adapted for dispensing the pad of material, and second opening 45. The first opening 43 is in alignment with the first aperture 21 of the cover and the second opening 45 is in alignment with the second aperture of the cover. The openings in the articles are typically formed by die-cutting. Once assembled, as best shown in FIG. 2, the article 40 covers substantially all of the inner surface 12 a of the cover.
In use, in one embodiment, the consumer is provided with at least one article bearing multi-dimensional image. A plurality of these articles can be provided and they can be coordinated with a particular holiday season (e.g., Easter, Christmas). Thus, the dispenser is designed to allow for different images to be displayed at different times by changing the article bearing the multi-dimensional image. The consumer aligns the article bearing the multi-dimensional image with the cover so that the apertures in the cover coincide with the openings in the article, loads the housing cavity with a pad of material, and then places the cover with the article on the housing.
In alternative embodiments, the cover may include mechanical means (such as, but not limited to, hooks, hook and loop fastening means) that allows for attachment of the article bearing the multi-dimensional image, thereby eliminating the need to rely on the consumer to align the article with the cover. In yet another embodiment, the article bearing the multi-dimensional image can be attached adhesively to the cover, so long as the adhesive does not visually detract from the image. The adhesive may be repositionable, allowing for easy removal of the film bearing the multidimensional image and for replacement of a different film containing a different image.
In a lenticular film, a plurality of linear corrugations or grooves that are molded, embossed, or extruded. Such films are typically colorless, although they can be tinted. A one-dimensional image can be printed onto a base sheet and attached, such as by a lamination process, to the lenticular film. Alternatively, a photo can be used as the image. The combination of the printed base sheet or photo with the lenticular film transforms the one-dimensional image into a multi-dimensional image. Care should be taken to align the image with the lenticular film to produce a quality multi-dimensional image. If desired, the printed image or photo can be subjected to known photography techniques where commercially available software can be used to alter the picture so it is better suited with the lenticular film. As stated above, in an alternative embodiment, the lenticular film is the article bearing the multi-dimensional image. Commercially available lenticular films that may be used in the present invention include those supplied from LentiClear™ Lenticular Lens, Inc. in Itasca, Ill. under product name LentiClear™ Elliptical High Performance Lenticular Lens.
U.S. Pat. No. 6,288,842 discloses another useful article for use in the present invention, where various types of microlens sheeting with composite images are described. The composite image may be two-dimensional or three-dimensional. The image floats above and or below the sheeting. Suitable microlens sheeting that can be processed to include the composite images include exposed lens sheeting, embedded lens sheeting, encapsulated lens sheeting, and microlens sheeting comprises a transparent plano-convex or aspheric base sheet. The exposed lens type of microlens sheeting that includes a monolayer of transparent microspheres partially embedded in a binder, as described in greater detail in U.S. Pat. No. 2,326,634. The embedded lens type sheeting that includes a monolayer of transparent microspheres embedded in a transparent protective overcoat, as described in greater detail in U.S. Pat. No. 3,801,183. The encapsulated lens type sheeting is described in U.S. Pat. No. 5,064,272. The transparent plano-convex or aspheric base sheet has first and second broad faces, the second face being substantially planar and the first face having an array of substantially hemispheroidal or hemi-aspheroidal microlenses, as better described in U.S. Pat. No. 5,254,390.
Articles bearing holograms may also be used in the present invention. Holograms are typically generated by using small prisms or small ridges that scatter to diffract light in a periodic fashion. There are commercially available films that generate holograms.
Although specific embodiments of the present invention have been shown and described, it is understood that these embodiments are merely illustrative of the many possible specific arrangements that can be devised in application of the principles of the invention. Numerous and varied other arrangements can be devised in accordance with these principles by those of ordinary skill in the art without departing from the spirit and scope of the invention. Thus, the scope of the present invention should not be limited to the structures described in this application, but only by the structures described by the language of the claims and the equivalents of those structures.
