  • the sheet dispenser is a non- shuttling dispenser, it is more compact (i.e., has a smaller footprint) than the dispenser described in US Patent Nos. 4,770,320; 4,907,825; 6,719,472 and 6,837,395 where the stack typically shuttles from one end wall to the opposite end wall when a sheet is removed.
  • the inventive dispenser can be integrated into writing instruments, which inherently has limited space, at a smaller footprint.
  • the compactness of the inventive dispenser allows for efficient use of space, which becomes more and more important for many people, including on-the-go workers, who may not have a dedicated work area but instead move from one work area to another.
  • shuttling dispenser generally means that upon initiating the removal of a first sheet in the stack through the slot, the next subsequent sheet also begins the dispensing process by moving into the slot without requiring the stack to first move from one end wall to an opposing end wall of the dispenser. In this way, the end walls of the dispenser that defines the length of the dispenser is only slightly larger than the length of the stack of sheets.
  • FIG. IA depicts an enlarged sectional side view of a prior art sheet dispenser having a stack of sheets in a first position with a first sheet within the stack extending through a slot in the sheet dispenser;

  • Figure 7 depicts a cross-sectional view of embodiment of Figure 4.
  • Sheet dispenser 10 comprises housing having an upper housing portion 11 attached to a lower housing portion 13.
  • Upper housing portion has an upper surface 14 and side walls 15 suitable for containing a stack of sheets.
  • Upper housing portion may be temporarily or permanently attached to lower housing portion 13 along perimeter 16.
  • Sheet tab portion 17 extends from the dispenser through slot 18 in upper housing portion.
  • a stack of sheets 30 is positioned within the housing of the sheet dispenser.
  • the stack of sheets comprises, for ease of discussion, seven individual sheets referred to herein as sheets 20a to 2Og. As a user removes first individual sheet 20a from the dispenser, the stack moves from a first position 31 towards a second position 32 within the dispenser.
  • Figures IB to ID below further describe the shuttling motion.
  • portion 202b of second individual sheet 20b is positioned near the mouth of slot 18.
  • adhesive layer 24a on a lower surface of first individual sheet 20a remains adhered to individual sheet 20b and causes portion 202b of second individual sheet 20b to exit slot 18.
  • Figure ID depicts a final stage in the shuttling motion, wherein the stack of sheets is in second position 32, first individual sheet 20a has been completely removed from the dispenser and disconnected from second individual sheet 20b, and a portion of second individual sheet 20b extends through slot 18. At this stage, the stack of sheets is in position to shuttle back to first position 31 when individual sheet 20b is fully removed from the dispenser.
  • This prior art dispenser has a length that is longer than that of the stack of sheets by a distance generally denoted as reference "L".
  • Figure 2 shows a side view of an exemplary stack 130 of sheets releaseably adhered to one another in a fan-fold configuration and, for purposes of discussion, expanded in an accordion-like manner.
  • the stack includes seven sheets, 120a to 12Og. Each sheet has a tab end portion and an adhesive end portion.
  • first sheet 120a has a tab end portion 120ax and adhesive end portion 120ay.
  • second sheet 120b has a tab end portion 120bx and adhesive end portion 120by.
  • Each sheet also includes opposing first and second surfaces.
  • the first surface is adhesive free and preferably writeable.
  • An adhesive coating 124 is disposed on the second surface and at the adhesive end portion.
  • the tab end portion is adhesive free on both of its first and second surfaces.
  • a plurality of sheets is stacked together such that the adhesive on any two adjacent sheets lie at opposing ends of the stack.
  • the sheets and the resulting stack of sheets are rectangular.
  • the stack has a length that is equal to its longest side.
  • adhesive coating 124 covers about 45% to 55% of the surface area of the second surface of the sheet. Preferably the adhesive covers about 50% of the surface area.
  • the stack of sheet will no longer be able to fan out in like an accordion because of the adhesive overlap from one sheet to the next subsequent sheet. Because of the fan-fold configuration, the overlap occurs at the midsection of the stack. Thus, a stack of sheets where each sheet has about 60% adhesive coverage would result in a stack that is essentially a block of sheets. While the present invention is operable where individual sheets have adhesive coverage of 60%, the force required to dispense such a sheet from the stack can be excessively high, which is an undesirable feature for the consumer. Furthermore, in a flag application wherein the sheet is typically used to mark or to index a document, each sheet needs to have a sufficient amount of adhesive so as to remain adhered to the document. Thus, while the present invention is operable with a sheet having less than 45% adhesive coverage, such a sheet may not be as useful in a flag-type application.
  • the tab end portion of the sheet is brightly colored to highlight the area of the document that has been marked. Any color can be used, so long as it is capable of attracting a consumer's attention. If desired, the tab end portion can also include indicia or graphics.
  • the adhesive end portion is substantially transparent, so as not to obscure any text present on a document that may happen to lie underneath the sheet.
  • the sheet can be made of a variety of materials including paper, synthetic paper, and polymeric films. In a preferred embodiment, the sheet is a polymeric film such as, but not limited to, cellulose acetate and polypropylene.
  • Figures 3A and 3B depict enlarged sectional side views of one exemplary sheet dispenser of the present invention 110 equipped with a stack of sheets 130.
  • the dispenser has a longitudinal axis, generally denoted as reference line 125.
  • the dispenser has a second axis that is disposed transverse to the longitudinal axis, the transverse axis being denoted as reference line 128.
  • the dispenser includes an upper member 112 having a centrally located slot 118 disposed transverse to the longitudinal axis at about the midpoint along the length of the dispenser.
  • the slot divides the upper member into two substantially equal portions.
  • a first portion includes a first upper wall 112a.
  • the second portion includes a second upper wall 112b.
  • Four lateral walls 115 extend from the upper walls.
  • the lateral walls include two opposing end walls, a first end wall 115a and a second end wall 115b. The distance between the two end walls defines the length of the dispenser.
  • the dispenser includes a lower member 113. The upper member is at least temporarily attached to the lower member via the lateral walls to form a housing.
  • Each sheet in the stack has about 50% adhesive coverage, although as previously stated, the adhesive coverage can be from about 45% to 55%.
  • each of the first and second upper walls, 112a and 112b respectively contact more than about 40% of the surface area of the top most sheet 120a.
  • a first sheet 120a in the stack has its tab end portion 120ax extending through the slot. The adhesive end portion 120ay remains inside the housing such that the repositionable adhesive 124 of the first sheet is in contact with the tab end portion of a second sheet 120b.
  • the point at which the tab end portion meets with the adhesive end portion is referred to herein as the "adhesive line" or an “interface” and is generally denoted as reference line 127.
  • the interface lies underneath the slot.
  • Figure 3A shows the interface lies at about the middle of the slot, although it can lie anywhere along the slot width as further described below.
  • a pulling force is exerted on the second sheet 120b to force a portion of the second sheet, in this case the tab end portion 120by, into the slot.
  • a next adjacent sheet also begins the dispensing process by folding in the slot.
  • FIG. 3C shows a perspective view of the dispenser of Figure 3A and 3B.
  • the dispenser has a slot width, labeled as S w , parallel to the longitudinal axis 125. In one embodiment, the slot width is from 1% to 10% of the length of the stack of sheets.
  • the slot width is from 1% to 5% of the length of the stack of sheets.
  • the slot has a length that is sufficient large to allow an individual sheet to extend through the slot.
  • the slot length is slightly less than the distance between the two lateral walls that lie parallel to the longitudinal axis 125.
  • the dispenser has a length that is substantially equal to the distance between the two lateral end walls 115a and 115b.
  • the dispenser has a length that is at most 110% of the length of the stack of sheets, thereby minimizing the footprint of the dispenser.
  • the exemplary sheet dispenser as shown in Figures 3A, 3B, and 3C has a rectangular shape and is suitable for dispensing rectangular sheets. It should be noted that the sheet dispensers and sheets of the present invention may have any other shape. Suitable alternative shapes include, but are not limited to, square, circular, oblong, rhombus, trapezoidal, barbell, diamond, or any other shape. In any of these shapes, the stack of sheets will have a length that is equal to the longest linear dimension of the stack. For example, in the case of a square stack, the longest linear dimension of a square stack is the diagonal of the square. For a circular stack, the longest linear dimension is the diameter. For the ellipse, the longest linear dimension is its major axis.
  • the sheet dispenser is described as having separate upper and lower members. It should be noted that the upper and lower member can be formed integrally and have an opening therein for inputting a new stack of sheets.
  • the dispenser may be made from a variety of materials including, but not limited to, plastic, paper, glass, metal, or a combination thereof. Desirably, the dispenser is formed from a moldable plastic material.
  • the upper member comprises a molded plastic material and the lower member comprises a paper substrate. In some cases, it is desirable for the upper member to be formed from a transparent material so that a user can see the interior of the sheet dispenser.
  • Figures 4 to 7 depict various views of a writing instrument integrated with the dispenser of the present invention.
  • An illustrative writing instrument includes, but is not limited to, a highlighter, a pen, a marker, and a pencil.
  • Figure 4 depicts a perspective view of an unassembled writing instrument 200 without a writing element.

  • Dispensing Force Test Method The force required to dispense a polymeric sheet, having dimensions of 0.375 inch (9.5 mm) wide by 1.75 inch (44.4 mm) long, from a stack of sheets was done using an Instron machine. The sheets were stacked in a fan-fold configuration. The stack was held in a dispenser integrated with a writing instrument, such as a Post-it ® Flag Highlighter, available from 3M Company. US Patent No. 6,179,472 shows a schematic view of the dispenser used in this testing. The dispenser had a length of about 2.3 inch (59 mm) with a slot width of about 0.0625 inch (1.6 mm). The highlighter was attached to the Instron fixture using double sided tape. In addition, two pieces (about 5 inches in length) of Scotch ® Magic tape, product no. 810, was used to further secure the highlighter to the fixture. The two tape pieces straddled the dispenser region of the highlighter.
  • the tab end portion of the sheet was fed into the jaws of the Instron fixture, which pulled the tab end portion from stacks of sheets inside the dispenser at a rate of about 100 inches per minute. This type of testing is similar to a 90 peel test commonly used in evaluating peel adhesion. The peak force required to dispense the sheet was then recorded in gram- force.
  • the dispenser discussed in the "Dispensing Force Test Method" above was retrofitted with two spacers, each about 7.6 mm in length and 9.5 mm wide. Each spacer was used to block an end of the dispenser. Thus, the effective length of the dispenser was about 43.8 mm, or a reduction of about 25% from the original length.
  • Example 1 This example was done as in Example 1 above except that each of the flag had a minimum repositionable adhesive coverage of greater than about 60% (on average, about 63%) on its second surface at its second end.
  • three different stacks were used for a total of 25 samples. The stacks were manufactured by 3M Company, St. Paul, MN and sold as part of the Post-it ® Flag Highlighter as flag refills. The peak load required to dispense each sample is reported in Table 1 along with the average of the peak load values.
  • the dispensing force for the inventive compact, non- shuttling dispenser is about an order of magnitude less than the dispensing force for a prior art flag, i.e., a flag having on average about 63% adhesive coverage on its second side, dispensed through the same compact non-shuttling dispenser.
  • a prior art flag can be dispensed through the non-shuttling dispenser of the present invention
  • the pulling force required to remove (i.e., to dispense) the flag is on average about 749 grams, which is similar to having a consumer forcefully yank the flag out of the dispenser. Such a high dispensing force is undesirable.
