The present invention relates to an open top dispenser. In particular, the present invention relates to a dispenser that allows for easy loading and reloading of pads of repositionable notes of different sizes. The dispenser is particularly suited for dispensing repositionable notes in a z-stacked configuration.
BACKGROUNDRepositionable paper notes are used widely today. Some notes are assembled in a z-stacked (also referred to as “fan fold”) construction. In such a construction, the note, typically square, but can also be rectangular, or special die cut shaped, has opposing front and back surfaces. On the back surface, along an edge or region of the note is a stripe of repositionable adhesive. The front of the note may contain a release coating. The notes are stacked so that the adhesive stripe of each note is positioned on alternating ends of the pad of notes. Commercially available pads of repositionable notes are available from 3M Company under the Post-it® brand.
There are a wide variety of dispensers for pads of repositionable notes. Examples of commercially available dispensers include those from 3M Company, St. Paul, Minn., such as the Designer Series Pop-Up Notes Dispenser, DS440-VP or DS330-VA for 4 by 4 inch or 3 by 3 inch notes respectively, the Professional Design Pop-Up Notes Dispenser, PRO440-VP or PRO330 for 4 by 4 inch or 3 by 3 inch notes respectively. 3M also offers a Professional Design Pop-Up Dispenser PRO331-RB for 3 by 3 inch note with a pen holder where the dispenser is mountable on a vertical surface. These dispensers offer attractive designs and are functional.
There is a continuing need for different dispensers for the market place.
SUMMARYIn one aspect, the invention pertains to a dispenser having a primary cavity having first and second sides and an open end and a closed end, the open end allowing for the insertion and the removal of a pad of notes. The dispenser further comprises a base defining the closed end of the dispenser; front and rear portions, each portion having first and second ends and opposing inside and outside surfaces, the front and rear portions disposed on the base such that the second end of each portion is proximate to the base, the front portion comprises a slot extending from the first end to the second end; and a biasing mechanism disposed proximate the rear portion.
An advantage of the present invention is that it provides the user with the versatility of using differently sized pads of repositionable notes. In one exemplary application, the dispenser is mounted on a vertical surface and has a cavity for holding writing instruments providing the user with added convenience.
Most commercially available dispensers require two motions or steps to load a pad of repositionable notes, such as, e.g., one motion to open a cover and a second motion to load the pad. Alternatively, one motion is used to depress a plunger in the dispenser and another motion is used to slide in the pad. One advantage of present invention is that it allows the loading of the pad in one motion, simply by sliding the pad into the opening of the dispenser. The sliding action simultaneously depresses a plate on the biasing mechanism and loads the pad, as further explained in detail below.

These figures are idealized, are not drawn to scale, and are intended merely for illustrative purposes.
DETAILED DESCRIPTIONIn this particular embodiment, the front and rear portions are separate components joined together at side seams 50a and 50b. In another exemplary embodiment, the front and rear portions are formed as an integral unit. In yet another exemplary embodiment, the front and rear portions and the base are formed as an integral unit. Optionally, the front and or back portion can be made with translucent materials and can further include indicia and or graphics.
Disposed on outside surface 31 of the rear portion is means for attaching the dispenser to a surface, such as work surfaces, walls, refrigerator doors, and the like. This particular embodiment shows that one exemplary means for attaching the dispenser is a composite 60 having releasable adhesive strip 62 and hooking devices 64 that would mate with complementary hooking devices pre-attached to the surface. Exemplary releasable adhesive strip products are available from 3M Company under the Command™ brand of product lines.
The dispenser can be made of a variety of materials including, plastics, metals, and woods. Suitable plastic materials include, but not limited to, ABS (acrylonitrile-butadiene-styrene polymer) and polystyrene.
In one embodiment, the dispenser has a length L of 5½ inch, a height H of 3.63 inch, and a depth D of 1 inch. The dispenser has a first internal wall disposed 1 inch from its first side (depicted schematically as L2 in
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.
