The present invention is directed to sheet dispensers and uses for sheet dispensers. The present invention is further directed to methods of making sheet dispensers and applications using sheet dispensers.
Sheet dispensers are known in the art. Various sheet dispensers are disclosed in U.S. Pat. No. 4,770,320 issued to Miles et al., U.S. Pat. No. 5,411,168 issued to Mertens et al., U.S. Pat. No. 5,551,595 issued to Mertens et al., and U.S. Pat. No. 5,755,356 issued to Bastiaens et al., all of which are assigned to 3M Innovative Properties Company (St. Paul, Minn.), and all of which are herein incorporated by reference. Known sheet dispensers provide sheets or flags, such as Post-its® notes or flags, to a user.
The present invention is directed to new sheet dispensers, which provide sheets to a user, but also provide one or more additional features.
The present invention is directed to new sheet dispensers, which provide one or more types of feedback to a user and/or one or more unique functions. The sheet dispensers of the present invention provide one or more types of feedback and/or functions due to the movement of a stack of sheets within the sheet dispenser. As a user removes a sheet from the sheet dispenser, the stack of sheets moves from a first location to a second location within the sheet dispenser. This movement of the stack of sheets either directly or indirectly provides feedback to a user and/or some event to take place. Examples of feedback include, but are not limited to, visual feedback, audio feedback, aromatic feedback, or a combination thereof. Exemplary events include, but are not limited to, associating data with a given sheet removed from the sheet dispenser.
In one exemplary embodiment of the present invention, the sheet dispensers provide visual feedback to a user, wherein the visual feedback is indicia, which is at least partially blocked from view by the stack of sheets. As the stack of sheets moves from a first location to a second location within the sheet dispenser, the indicia becomes viewable to a user. The indicia may be any indicia including, but not limited to, printed text, handwritten text, artwork, etc. The sheet dispenser may be utilized as an advertising media by providing visual feedback to a user in the form of a company logo or slogan. In addition, the advertising sheet dispenser may also provide audio feedback in the form of sound alone or in combination with visual advertising feedback. For example, the sheet dispenser may provide visual feedback in the form of a company name or logo, as well as, audio feedback in the form of a company slogan or theme song.
In other exemplary embodiments of the present invention, the sheet dispensers provide one or more unique functions resulting in the occurrence of an event. For example, the sheet dispenser may act as a switch to turn “on” or “off” a switch-activated device, such as a lamp, a sound system or an alarm clock. In this embodiment, as the stack of sheets moves from a first location to a second location within the sheet dispenser, the movement of the stack of sheets causes a signal (or electrical current) to be sent to a signal-receiving device (or switch-activated device).
The sheet dispensers of the present invention may also function as a room deodorizer providing aromatic feedback, such as a desirable scent. In this embodiment, removal of an individual sheet may produce the aromatic feedback. Alternatively, movement of the stack of sheets from a first location to a second location within the sheet dispenser may cause a signal (or electrical current) to be sent to a scent-generating device, which produces the aromatic feedback.
In yet a further embodiment of the present invention, the sheet dispensers provide a flame for use as a match or other fire-starting device. In this embodiment, removal of an individual sheet may produce the flame. Alternatively, movement of the stack of sheets from a first location to a second location within the sheet dispenser may cause a signal (or electrical current) to be sent to a fire-starting device, which produces the flame.
The present invention is also directed to methods of using the new sheet dispensers, and systems containing at least one sheet dispenser of the present invention. The sheet dispensers of the present invention may be used in an office or home environment to provide one or more types of feedback to a user and/or one or more unique functions. As discussed above, the sheet dispensers of the present invention may be used as a switch for activating a switch-activatable device. The sheet dispensers may cooperate with a signal-receiving device, such as a personal computer, for associating data with a given sheet removed from the sheet dispenser. Other applications include, but are not limited to, use as an advertising media, use as a room deodorizer, use as a flame-generating device, and combinations thereof.
The present invention is further directed to methods of making sheet dispensers, which provide one or more types of feedback and/or functions as described above.

No. 5,755,356 issued to Bastiaens et al., all of which are assigned to 3M Innovative Properties Company (St. Paul, Minn.), and all of which are herein incorporated by reference. A description of exemplary sheet dispensers of the present invention, methods of making sheet dispensers, and uses is given below.
I. Sheet Dispenser Components
Sheet dispensers of the present invention comprise one or more components as described below.
A. Housing
An exemplary sheet dispenser is shown in
The exemplary sheet dispenser as shown in
Housing 11 of sheet dispenser 10 may comprise a variety of materials including, but not limited to, plastic, paper, glass, metal, or a combination thereof. Desirably, housing 11 is formed from a moldable plastic material. In one embodiment of the present invention, upper housing portion 12 comprises a molded plastic material and lower housing portion 13 comprises a paper substrate. In some cases, it is desirable for the upper housing portion 12 and/or the lower housing portion 13 to be formed from a transparent material so that a user can visually inspect the interior of sheet dispenser 10 enclosed by upper housing portion 12 and lower housing portion 13.
In a further embodiment of the present invention, the sheet dispenser comprises a transparent upper housing portion 12 and a lower housing portion 13, wherein an upper surface of lower housing portion 13 is coatable or printable. Printed messages, slogans, symbols, handwritten notes, or any other indicia may be adhered to, coated, printed, or written onto the upper surface of lower housing portion 13 as described below with reference to
Although not required, upper housing portion 12 and/or lower housing portion 13 may further comprise stack restrictors (not shown) along one or more interior edges of upper housing portion 12 and/or lower housing portion 13. The stack restrictors restrict the movement of the stack of sheets within housing 11 so that the stack of sheets moves in a single, straight shuttle pathway between a first position and a second position within sheet dispenser with substantially no movement perpendicular to the single shuttle pathway.
B. Stack of Sheets
The sheet dispensers of the present invention further comprise a stack of sheets positioned within housing 11 of sheet dispenser 10. The stack of sheets comprises one or more sheets releasably attached to one another to form a stack. An exemplary individual sheet suitable for use in the stack of sheets is shown in
As shown in
One or more individual sheets 20 may be combined to form a stack of sheets suitable for use in the sheet dispenser of the present invention.
As shown in
In
The movement of stack of sheets 30 to one or more intermediate positions or “stops” between a first position 31 and a second position 32 may be facilitated by using a stack of sheets formed from individual sheets as shown in
As shown in
It should be noted that two or more separate and disconnected adhesive coatings (e.g., coatings 46 and 47) may be present on a lower surface of an individual sheet in order to have multiple intermediate stops as the individual sheet is removed from sheet dispenser 10. Further, the location of the adhesive coatings may be adjusted along the lower surface of each individual sheet to control the “stop” locations of stack of sheets 30 within sheet dispenser 10 between first position 31 and second position 32.
It should be understood that other methods of producing multiple intermediate stops may be used in the present invention in addition to or independent from multiple adhesive coatings as described above. For example, stack of sheets 30 may be stopped mechanically at multiple locations between first position 31 and second position 32 within sheet dispenser 10 by placing mechanical barriers along the pathway between first position 31 and second position 32. Suitable mechanical barriers may include, but are not limited to, protrusions extending upward from the lower housing portion 13, protrusions extending downward from the upper housing portion 12, protrusions extending horizontally from side walls 15 of upper housing portion 12, or combinations thereof. In some embodiments of the present invention, a mechanical switch or electrical contact may be used to temporarily stop stack of sheets 30 between first position 31 and second position 32.
In a further embodiment of the present invention, individual sheets 40 may be coated with high release material and low release material to provide low adhesion and higher adhesion between adjacent sheets. For example, an upper surface of each individual sheet 40 may be coated with (1) one or more strips of high release material to provide one or more areas of low adhesion between adjacent sheets, and (2) one or more strips of low release material to provide one or more areas of higher adhesion between adjacent sheets. As a user pulls on an individual sheet, the stack of sheets 30 moves from first position 31 to one or more intermediate positions between first position 31 and second position 32 depending on the number of high adhesion regions on the individual sheet (i.e., the pulling force extended by a user is enough to overcome a single high adhesion region).
The dimensions of stack of sheets 30 may vary depending on a number of factors including, but not limited to, individual sheet size, number of individual sheets in the stack, and the dimensions of the sheet dispenser. The height of stack of sheets 30, hs, is less than housing height, hh, in order to provide free movement of stack of sheets 30 within sheet dispenser 10. Typically, the height of stack of sheets 30, hs, is less than about 90% of housing height, hh. Desirably, stack of sheets 30 contains from about one to about 500 individual sheets, more desirably, from about one to about 100 individual sheets.
Individual sheets 40 within stack of sheets 30 may also have a given shape and dimensions, which vary depending on the given application. Although individual sheets are described throughout the present invention as having a rectangular shape, it should be noted that individual sheets may have any shape. Suitable shapes include, but are not limited to, rectangular, square, circular, oblong, rhombus, trapezoidal, barbell, diamond, or any other shape. Typically, each individual sheet has a thickness ranging from about 0.001 to about 0.01 centimeters. As discussed above, individual sheets 40 may be formed from a variety of sheet-forming materials. Suitable sheet-forming materials include, but are not limited to, plastics, paper, metal, or combinations thereof. Desirably, the sheet-forming material comprises a polymeric material, such as, polyester (PET), polypropylene, or cellulose acetate.
Stack of sheets 30 may comprise individual sheets 40 without additional components or may comprise one or more additional components. In one embodiment of the present invention, stack of sheets 30 comprises one or more individual sheets 40 positioned on a substrate referred to as a “backsheet” (shown and described further in
A variety of adhesives may be used to form an outer coating on the individual sheets including, but not limited to, repositionable pressure sensitive adhesives and permanent PSAs. Examples of suitable repositionable pressure sensitive adhesives include, but are not limited to, repositionable pressure sensitive adhesives disclosed in U.S. Pat. No. 3,691,140 issued to Silver, and U.S. Pat. No. 4,166,152 issued to Baker et al., both of which are herein incorporated by reference in their entireties.

It should be understood that in any of the above described sheet dispensers including those suitable for use as an advertising medium, individual sheets within the stack of sheets may be printed or coated with a desired image, indicia or message to a user.
B. Use as a Switch
In one desired embodiment of the present invention, the sheet dispensers may be used to provide a unique function, namely as a switch as described above. The sheet dispenser switch may be used to turn “on” or “off” one or more electrical devices. The sheet dispenser switch may be activated by one or more methods described below.
In one embodiment of the present invention, a first method of activating a switch is disclosed, wherein the method comprises a step of at least partially removing a first sheet from a stack of sheets within a sheet dispenser, wherein the step of at least partially removing a first sheet moves the stack of sheets from a first position to an intermediate position between the first position and a second position within the sheet dispenser (as was previously described with respect to
In the first method or the second method, the method may further comprise one or more of the following steps:
C. Use as a Switch In Combination With A Personal Computer
In a further desired embodiment of the present invention, the sheet dispenser is used in combination with a personal computer to provide a particular function and/or feedback to a user, namely, the ability to associate data inputted into a computer with a particular flag removed from the sheet dispenser. The sheet dispenser may be connected to a personal computer via a USB port. Each sheet removed from the sheet dispenser may be associated with a set of data entered into the personal computer via a user interface, such as a keyboard, document scanning device, etc. For example, a sheet removed from the sheet dispenser may be placed on a document to flag the document. Data related to the document may already be in the personal computer or may be entered immediately prior to or after removal of the sheet from the sheet dispenser.
In this embodiment, a method of associating a set of data with one or more sheets removed from a sheet dispenser is disclosed, wherein the method comprises (a) at least partially removing a first sheet from a stack of sheets within a sheet dispenser, wherein the step of at least partially removing a first sheet shifts the stack of sheets from a first position to a second position within the sheet dispenser; and (b) inputting a set of data into a personal computer via a user interface, wherein the set of data is associated with the first sheet.
In this embodiment, computer software on the personal computer may be used to monitor the activity of the switch. Upon receiving a signal generated by the switch in the dispenser (i.e., a change in position of the stack of sheets), the software executes one or more appropriate actions, such as initiation of KwikTag™ software, a software package commercially available from ImageTag, Inc. (Chandler, Ariz.). Coupling of the sheet dispenser of the present invention with the KwikTag™ software leads to a number of desirable results.
Prior to the present invention, a user was required to enter a barcode value from a first tag (or sheet) of a new pad (i.e., stack of sheets) into the KwikTag™ software. After each tag (or sheet) was dispensed and attached to a document, the user was required to launch the software, enter the tag number on the document, move to the data entry interface, and then add descriptors for the document to be scanned. While the KwikTag™ software was sophisticated enough to assist the user in every phase of this operation, the loose coupling of (1) the tag dispensing operation, (2) the scanning of documents, and (3) the entry of data offered significant opportunity for errors, especially omission errors. As with any loosely coupled system, the opportunity for tags and associated data to become “out of sync” was significant and created a generally unsatisfactory system.
The present invention eliminates possible errors in the above-described process. In one embodiment of the present invention, a user still enters the first barcode number from the first sheet of a new pad (or stack or sheets). When a document is to be scanned, a tag is dispensed. The resident software on the PC senses the dispenser's switch activation, and launches the KwikTag™ software. The interface of the software is immediately switched to the data entry interface, with the barcode number of the current tag. Upon completing the data entry, the user submits the document description, the counter increments by one, and the KwikTag™ software closes. The resident software then continues to monitor the USB port for further sheet dispensing. Bar codes from additional tags removed from the sheet dispenser are already calculated by the software, eliminating the need to input additional barcode information. By tying the dispensing action directly to the data entry interface, the coupling between the physical, tagged document and its associated digital data is tightened significantly, increasing system accuracy and user satisfaction, while streamlining the document archiving process.
D. Use as a Scent-Generating Device
In another embodiment of the present invention, the sheet dispensers may be used as a scent-generating device as described above.
E. Use as a Flame-Generating Device
In yet another embodiment of the present invention, the sheet dispensers may be used as a flame-generating device as described above.
F. Use as a Switch and a Scent-Generating Device
In a further embodiment of the present invention, the sheet dispensers may be used as both a switch and a scent-generating device (or a flame-generating device) as described above. For example, the switch component of the sheet dispenser may turn off an alarm clock when a sheet is removed from the sheet dispenser, while the scent-generating component provides a fresh scent to aid in waking-up a user.
While the specification has been described in detail with respect to specific embodiments thereof, it will be appreciated that those skilled in the art, upon attaining an understanding of the foregoing, may readily conceive of alterations to, variations of, and equivalents to these embodiments. Accordingly, the scope of the present invention should be assessed as that of the appended claims and any equivalents thereto.
