Definitions

  • the present disclosure relates to a dispenser configured to contain and dispense a stack of sheet products.
  • sheet product dispensers in which sheet products are dispensed from a product housing through a dispensing opening.
  • Examples of types of sheet products that are known are hand towels, toilet tissue, napkins, serviettes, and other wiping products in sheet form.
  • a persistent problem with such dispensers is that users may take more than is required, causing waste.
  • dispensers are known that dispense a predetermined number of sheet products.
  • Dispensers of this type rely on precise settings, depending on the thickness of the sheet products and/or the level of compression of the stack. Further, dispensers of this type require difficult adjustments to be made in order to vary the predetermined number of sheet products to be dispensed, and are therefore often used so as to always dispense the same number of sheet products.
  • US 2010/0224647 A1 discloses a paper product dispensing system comprising a paper product holder, movable grasping fingers, and a collection tray.
  • an actuation mechanism comprises a gear mechanism providing transmission between a user interface part or parts of the actuation mechanism and a dispensing member of the dispensing mechanism, wherein the gear mechanism is configured so that an actuation stroke of differing user interface parts causes a driving member of the dispensing mechanism to dispense the differing number of sheet products.
  • US 2010/0114366 A1 discloses dispensers providing controlled dispensing and controlled dispensing methods.
  • a dispenser according to claim 1 In a first aspect of the present invention, there is provided a dispenser according to claim 1.
  • a dispenser comprising a housing for a stack of sheet products and a dispensing opening, the dispenser comprising a dispensing member for engaging a face of a sheet adjacent the dispensing opening, the dispensing member being moveable and adapted for gripping the sheet, whereby movement of the dispensing member causes the gripped sheet to slide relative to an underling sheet face in the stack to separate a sheet product adjacent the dispensing opening from the stack.
  • the dispensing member grips a sheet product adjacent the dispensing opening and causes it to slide relative to an underlying sheet product to allow the gripped sheet product to be moved relative to, and separated from, the remaining stack.
  • the stack is engaged at a face of the stack adjacent the dispensing opening and so does not rely on precise picking of a predetermined number of sheets.
  • a thickness of each sheet product from the edge side changes depending upon compression, and the compression changes depending upon weight or depth of the remaining stack.
  • the number of sheets can be controlled by setting an amount of movement of the dispensing member to dispense one sheet product and repeating this amount of movement for each further sheet product to be dispensed.
  • the amount a sheet is required to slide relative to an underlying sheet does not change depending on the number of sheet products in the remainder of the stack.
  • the first aspect allows a desired number of sheets to be dispensed in a consistent manner.
  • the dispenser housing is configured for holding the stack of sheet products in an interior volume thereof so that the front face of the stack is adjacent the dispensing opening.
  • the dispensing member is positioned to engage the front face of the stack and may protrude into the interior volume.
  • the dispensing member is positioned to press into the front face of the stack, in the stacking direction, so that the front-most sheet product in the stack is gripped and moved while being pressed against underlying sheet products in the stack. This causes the front-most sheet product at the location at which it is gripped to rub against underlying sheets in the stack as it is moved relative to the underlying sheets.
  • the stack may be weighted against or otherwise biased against the dispensing member.
  • the dispensing member is configured for moving a fold or edge of a sheet product by gripping and moving a face of the sheet product adjacent the fold or edge.
  • the dispensing member is configured for moving a fold or edge of a sheet product adjacent the dispensing opening along a face of an underlying sheet in the stack to separate that sheet product from the stack.
  • the dispensing member is configured for moving the sheet product past a barrier so that once the barrier is cleared, the sheet product passes through the dispensing opening.
  • the dispensing member itself serves as the barrier that has to be cleared for the sheet product to be passed through the dispensing opening.
  • the arrangement is such that the sheet product gripped by the dispensing member rubs against an underlying sheet product as it is moved by the dispensing member, but the frictional interaction of one face of the sheet product with the dispensing member is greater than the frictional force between the opposed face of the sheet product and the underlying sheet product in the stack, thereby allowing the gripped sheet product to move relative to a remainder of the stack in a sliding manner.
  • the dispensing member may have a suitably chosen surface that interacts with the surface of a sheet product adjacent the dispensing opening.
  • the surface is selected so as to achieve a relatively high frictional force with the sheet product.
  • the surface of the dispensing member may be made of an elastomeric material, it may be tacky to the touch, it may be textured such as by way of grooves aligned with the direction of movement or cross grooves, hatching, dimples or the like.
  • the skilled person would be able to suitably select the form and material of the dispensing member to ensure sufficiently high grip on the sheet products.
  • the dispenser comprises a support structure against which the dispensing face of the stack is supported.
  • the support structure may be configured to hold the stack in position against a weight of the stack (e.g., in a gravity feed dispenser) or for holding the stack in position against a biasing member acting on the stack (e.g., in an in-counter, on-counter or tabletop dispenser).
  • the dispensing face of the stack is pressed against the support structure by virtue of the weight of the stack or the urging provided by the biasing member.
  • the support structure includes at least one wall.
  • the support structure reveals part of the dispensing face and the dispensing member is positioned to engage the revealed part of the dispensing face of the stack.
  • the dispensing member is configured to move the sheet being gripped off the support structure to separate the sheet product from a remainder of the stack for dispensing from the dispensing opening.
  • the dispenser comprises a housing defining an interior volume in which the stack is disposed.
  • the stack includes a front face and a back face and four sidewalls extending there between.
  • the four sidewalls are made up of folds or edges of the sheet products in the stack, whereas the front face is made up of a major surface of the front-most sheet product or products and the back face is made up of a major surface of the backmost sheet product or products.
  • the dispensing member is positioned to operate on the front face of the stack. It is the front-most sheet product or products that are gripped by the dispensing member and moved relative to underlying sheets in the stack to dispense the sheet product.
  • the dispenser comprises a support structure for engaging and supporting a front face of the stack adjacent, in a stacking direction, the dispensing opening.
  • the dispensing member is positioned so as to engage the front face of the stack at or above the level of the support structure in the stacking direction. In this way, both the support structure and the dispensing member have the front face of the stack pressed thereon by virtue of the weight of the stack (i.e., by virtue of gravity) or by a biasing member.
  • the support structure in that embodiment is configured for engaging opposed margin areas of the front face of the stack.
  • the dispensing member is positioned in the space between the opposed margin areas to also engage the front face of the stack.
  • the dispensing opening is located between the part of the support structure engaging one of the margin areas and the dispensing member. The dispensing member is operable to move a sheet product that it grips and engages into the dispensing opening.
  • the support structure and the dispensing member are arranged so that one side of the sheet product is moved clear of the support structure into the dispensing opening, while another side of the sheet product remains supported by the support structure.
  • This is particularly useful in a gravity feed dispenser embodiment so that one side of the sheet product hangs through the dispensing opening for grasping by a user, while the other side remains pinched between the support structure and the remainder of the stack to keep the dispensing tidy.
  • An embodiment in which part of the sheet product is held by the support structure and another part is moved clear of the support structure by the dispensing member is discussed further below with respect to the third aspect.
  • one or more shelves are included to support the dispensing face of the stack adjacent the dispensing opening.
  • the dispensing member is positioned adjacent the shelf and is configured for moving the sheet off the shelf to separate a sheet product from the remainder of the stack for dispensing through the dispensing opening.
  • the dispensing member turns to provide the movement required to slide the sheet to separate the sheet product from the remainder of the stack.
  • An axis about which the dispensing member turns is disposed parallel to faces of the sheet products in the stack. The axis may also be aligned with a margin portion of the front face of the stack that the shelf or support structure engages.
  • the dispensing member is provided as a roller engaging the face of a sheet product adjacent the dispensing opening.
  • a peripheral surface of the roller grips the face of the adjacent sheet product.
  • the roller may define a cylindrical outer profile for engaging the sheet product or it may have a lobed outer profile.
  • the lobed outer profile may be useful for moving the gripped sheet product by a set amount as defined by the protruding portion of a lobe of the outer profile, while allowing relative rotation between the roller and the relatively recessed part of the lobed profile.
  • the lobed outer profile may have one, two, three, four or more lobes.
  • the roller may be configured for dispensing one sheet product per lobe.
  • the cylindrical outer profile allows greater tolerance in dispensing a predetermined number of sheet products because it does not require lobe registration.
  • the dispensing member is positioned closer to one edge of the front face of the stack than to an opposed edge.
  • the dispensing member is configured for moving the closer edge of a sheet product adjacent the dispensing opening into the dispensing opening for grasping by a user. This asymmetrical positioning of the dispensing member reduces the likelihood of slippage since there is a reduced distance to travel to dispense the sheet product.
  • the dispenser comprises an actuator that is user-operable to cause the dispensing member to move relative to the sheet products in the stack to dispense one or more sheet products.
  • the actuator may be as described below with respect to the second aspect.
  • the actuator may include a rotatable knob or it may include a button.
  • the rotatable knob can be rotated a different amount (e.g., a different number of turns or half-turns) to move the dispensing member by a different amount to dispense a different number of sheet products.
  • the actuator includes a plurality of buttons that may be selectively actuated to cause the dispensing member to move respective different amounts to thereby dispense different respective numbers of sheet products.
  • the dispensing member is moveable to move a sheet product adjacent the dispensing opening into or through the dispensing opening. As the preceding sheet is cleared by moving it into the dispensing opening, the dispensing member engages and grips a succeeding sheet for moving the succeeding sheet into or through the dispensing opening for grasping by a user.
  • the dispensing member is arranged to operate on the front face of a sheet product adjacent the dispensing opening so that when that sheet product moves into the dispensing opening and is clear of the dispensing member, the succeeding sheet product in the stack is engaged by the dispensing member.
  • a dispenser comprising a housing for a stack of sheet products, a dispensing opening, a dispensing member for dispensing a selected number of sheet products through the dispensing opening.
  • the dispenser also includes an actuator operatively coupled to the dispensing member that is user-operable to selectively cause the dispensing member to dispense a first predetermined number of sheet products and that is also user-operable to selectively cause the dispensing member to dispense a second, different (e.g., greater) number of sheet products.
  • the second aspect allows a user to operate an actuator to selectively cause one of at least two different numbers of sheet products to be dispensed. In this way, different dispensing requirements can be met in an easy to operate way.
  • the actuator is user-operable to selectively cause the dispensing member to dispense a third number, different from (e.g., greater than) the second number, of sheet products. In this way, small, medium and large sheet product requirements can be met.
  • the dispensing member moves to segregate a different number of sheet products from the remainder of the stack depending upon operation of the actuator to dispense the different number of sheet products.
  • the dispensing member is configured to turn relative to the stack, with the amount of turning differing depending upon operation of the actuator to dispense the different number of sheet products.
  • the dispensing member is a roller and the amount of rotation or number of revolutions of the roller differing depending upon operation of the actuator to dispense the different number of sheet products.
  • the dispensing member causes sliding movement of a sheet product adjacent the dispensing opening against an underlying sheet product in the stack. This, in turn, moves the sheet product relative to the remainder of the stack and into or through the dispensing opening. In an embodiment, the dispensing member engages a succeeding sheet product after dispensing the preceding sheet product so as to be able to move the succeeding sheet product into or through the dispensing opening by sliding against an underlying sheet in the stack.
  • the dispensing member is able to engage a succeeding sheet product in the stack once a sheet product adjacent the dispensing opening has been moved clear of the dispensing member so that both, the adjacent sheet product and the succeeding sheet product, may be dispensed.
  • the dispensing member moves by a first amount to thereby dispense the first number of sheet products and moves by a second, greater, amount to dispense the second number of sheet products.
  • the movement may be rotation.
  • a particular amount of movement e.g., rotation, dispenses one sheet product and an integer multiple of the particular amount of movement dispenses a corresponding integer multiple number of sheet products.
  • the actuator includes different user interfaces for actuating the different numbers of sheet products for dispensing.
  • the user interfaces may be, for example, buttons, levers, indexes, or electronic buttons.
  • the actuator and the dispensing member cooperate to dispense the number of sheet products depending upon the user interface operated.
  • the different user interfaces may be independently operable by a user to cause the different number of sheet products to be dispensed.
  • the different user interfaces are push buttons.
  • the different user interfaces are pressed by a user through an actuation stroke.
  • the gear assembly is configured so that an actuation stroke of different user interface parts causes the dispensing member to respectively dispense the different number of sheet products. That is, the gear assembly is configured to transmit different amounts of movement to the dispensing member despite the same length actuation stroke being applied to different user interface parts of the actuator.
  • the actuator comprises a converter for converting between types of motion so that the motion of a user interface part of the actuator in one direction is changed to motion in another direction or in another sense (i.e., linear to rotation or vice versa) of the dispensing member.
  • the converter may additionally or alternatively include mechanical advantage transmission.
  • the converter converts linear motion of an moveable part of the actuator to rotating motion of the dispensing member that is configured for engaging and moving one or more sheet products into or through the dispensing opening.
  • the actuator comprises a gear assembly providing transmission between a user interface part or parts of the actuator and a dispensing member.
  • an adjuster may be provided to allow adjustment in the amount of resulting movement of the dispensing member in a stroke of the actuator. This facilitates compensation for different degrees of slippage encountered between the dispensing member and sheet products having different slip properties.
  • the actuator has a defined stroke length defined between a moveable part of the actuator and a finger stop of a stationary part of the actuator.
  • the stroke length differs depending upon which user actuation interface is pressed. More specifically, in that embodiment, different stroke lengths correspond to different lengths of the path travelled by the moveable part to the finger stop.
  • an adjuster is provided to allow the user to change the stroke length.
  • a dispenser comprising a housing defining an interior volume for supporting a stack of sheet products, with the interior having a maximum depth in the stacking direction of the stack, and a maximum area perpendicular to the stacking direction.
  • the dispenser has a dispensing opening and stack support structure around the dispensing opening for engaging a front face of the stack having the maximum area on one side of the front face and on another side of the front face, and a dispensing member for releasing a sheet product at the one side of the front face of the stack to extend through the dispensing opening while the sheet product remains supported by the support structure at the other side of the front face of the stack.
  • the third aspect provides a dispenser in which sheet products such as napkins are present in a tidy and ready-to-grasp manner to the user.
  • the dispensing member releases at least one sheet product from one side, but does not release the other side, so that the sheet product is able to extend through or hang through the dispensing opening held or suspended from the other side.
  • the user can the reach into a grasping area of the dispenser adjacent the dispensing opening to take the at least one sheet product.
  • This two step, tidy dispensing process provides certainty as to the number of napkins dispensed, and prevents users from simply reaching in and grabbing an undetermined (typically large) number of napkins..
  • this aspect also provides a support structure around the dispensing opening that can be made small in size to minimize the risk of tearing.
  • the dispensing member may be a dispensing member according to the first aspect, with the dispensing member having the above releasing functionality while the support structure holds a side of the sheet product.
  • the dispensing member of the third aspect and its functionality with the support structure and dispensing opening may be combined with the second aspect so that the actuator is operable by a user to actuate the dispensing member.
  • the one side and the other side are opposed sides of the stack.
  • the maximum area is defined by a maximum x and a maximum y dimension (perpendicular x and y, as is conventional), wherein the one side and the other side are opposed in the y direction and the dispensing opening takes on the x dimension for at least part, optionally most, and optionally all, of the way between the one side and the other side.
  • the dispensing member is configured to engage and operate on the front face of the stack to move the one side of the sheet product off the support structure.
  • the dispensing member separates the engaged sheet product from the support structure at the one side and into the dispensing opening to clear the sheet product from the dispensing member so that the dispensing member engages an underlying sheet product.
  • the dispensing member is operable to subsequently release the underlying sheet product for extension through the dispensing opening.
  • the dispensing member includes a roller that is arranged to engage the front face of the stack and rotate to move the sheet product relative to the support structure on the one side to release the one side of the adjacent sheet product and to position that sheet product in/through the dispensing opening.
  • the dispensing member is configured to release a plurality of sheet products at the one side while the plurality of sheet products remains secured at the other side so that a plurality of sheet products extends through the dispensing opening.
  • the dispensing member may be configured to release the sheet products in a one-at-a-time fashion.
  • the dispensing member is configured to grip the sheet product and the dispensing member is operable to release the sheet product from the dispensing member to allow the sheet product to extend through the dispensing opening while being secured at the other side.
  • the dispenser is configured so that the stack is pressed against the support structure. This could be by way of gravitational force (gravity feed dispenser) or by way of spring force (table top, countertop or in-counter dispenser) or the urging force of some other biasing member.
  • gravitational force gravitation feed dispenser
  • spring force table top, countertop or in-counter dispenser

  • the finger stop 29 defines a stopping point for the stroke of the moveable actuator part 19.
  • the lower user interface ledge 27 has a shorter distance to move, before aligning with the finger stop 29, than does the upper user interface ledge 28.
  • the two distances thereby respectively define shorter and longer linear movements for the rack component 25, which in turn correspond respectively to smaller and larger amounts of rotation of the roller 15.
  • the user interface ledges 27, 28 respectively define a first number of sheet products for dispensing and a second, larger, number of sheet products for dispensing.
  • the first user interface ledge 27 may correspond to dispensing of one individual sheet product or it may correspond to dispensing of one fold of interfolded sheet products, which would for example thus yield/dispense two individual sheet products.
  • the second user interface ledge 28 may dispense twice this number, so it may dispense two individual sheet products or two folds of interfolded sheet products, specifically four individual sheet products.
  • the moveable actuator part 19 abuts against an abutment portion 42 that defines a rest position of the moveable actuator part 19 relative to the stationary actuator part 18.
  • the moveable actuator part 19 is biased to return to the starting position defined by the moveable actuator par 19 abutting against the abutment portion 42 of the stationary actuator part 18, such as by way of a spring.
  • the one-way clutch 24 allows rotation of the circular gear 23 to be transferred to the central shaft 14 of roller 15 when the user imparts linear motion to the rack component 25 by moving the moveable actuator part 19.
  • the spring returns the moveable actuator part 19 back to its rest position with the abutment portion 42, the one-way clutch 24 causes the circular gear 23 to disengage so as not to impart further rotational movement to the central shaft 14 or any other portion of roller 15.
  • FIG. 4 that figure shows the relative positions of the proximal shelf 22, the distal shelf 21 and the roller 15.
  • that figure shows the shelves 21, 22 and the outer surface of the roller 15 being positioned generally in alignment with respect to the stacking direction, so that the front face of the stack 10 contacts and is supported on the distal support shelf 21, the roller 15 and the proximal support shelf 22.
  • the roller 15 is positioned adjacent the proximal support shelf 22 and a dispensing opening 41 is defined in the gap between the distal support shelf 21 and the roller 15.
  • At least a portion of the outer surface of the roller 15 is positioned above the proximal support shelf 22 to cause the front face of the stack 10 to curve around the roller 15 to some degree, so as to ensure a large contact area and also sufficient pressure between the front-most sheet product and the roller 15, to avoid or at least minimize slippage.
  • the roller 15 functions to grip a major surface of part of a sheet product at the front of the stack, and to move it off the proximal shelf 22 by sliding same relative to an underlying sheet in the stack.
  • the roller 15 then passes the sheet product into the dispensing opening 41 once the fold or edge of the gripped sheet product is moved beyond the roller 15. Once a particular sheet product has been moved into/through the dispensing opening 41, the succeeding sheet in the stack will rest against the roller 15.
  • the roller 15 in this embodiment has a circular cross-section.
  • the outer surface of the roller 15 is required to grip the material of the sheet product.
  • the outer surface of the roller 15 may include sandpaper, may be textured, or may include dimples or ribs, or may be made of a material that has a high frictional relationship with the material defining the sheet product, such as an elastomeric material.
  • the outer surface may additionally or alternatively include a grooved or raised pattern such as a hatching pattern to increase grip.
  • the outer surface of the roller 15 may be provided by axially or radially extending teeth, with the teeth being angled toward or against the direction of rotation when dispensing a sheet product, or they may have a rectangular or sharp profile.
  • the roller 15 rotates so that the outer surface thereof moves in the direction away from the proximal shelf 22 and towards the distal shelf 21 at the location of engagement with the front face of the stack 10. This causes the sheet product to move away from the proximal shelf 22 and toward the distal shelf 21.
  • the roller 15 thus does not cause the sheet product to move off the distal shelf 21, so that the proximal part of the sheet product moves into/through the dispensing opening -41, while a distal margin of the sheet product remains supported on the distal shelf 21, pinched between the remainder of the stack and the distal shelf 21.
  • the sheet product gripped by the roller 15 will be released into/through the dispensing opening 41 to hang suspended from a distal margin at the distal shelf 21.
  • the support structure 12 may include proximal ribs extending in the stacking direction at the proximal shelf 22 for engaging a proximal side of a front portion of the stack 10 to ensure that the stack is suitably urged toward the roller 15.
  • the height of the proximal shelf 22 in the stacking direction may be adjusted, for example by a user operable adjuster, in order to relieve or increase this pressure so that the configuration of the support structure 12 is optimized to ensure that the correct number of sheet products is dispensed according to a user's choice at the actuator 2.
  • a fill line 6 indicates to a user a stack level that should be maintained for desired function of the dispenser.
  • a weight could be applied in addition to the stack weight to ensure suitable pressure on the roller 15.
  • a biasing element such as a spring, could push the stack onto the roller 15.
  • a support chute 4 is provided that is positioned beneath the dispensing opening 41.
  • the support chute 4 is located beneath the distal shelf 21 so that sheet products hanging in the dispensing opening 41, suspended at the distal margin, lie on the support chute 4.
  • the support chute functions to relieve some of the weight of the sheet product tending to pull that sheet product away from the distal shelf 21, which would result in undesirable complete or uncontrolled release of the sheet products from the support structure 12.
  • the support chute 4 includes a peripheral cut-out 30 positioned so that the hanging sheet product or products lie over the cut-out 30, thereby allowing a user to grasp the hanging sheet product(s) from both sides, one side through the cut-out 30.
  • the support chute 4 is angled so as to curve the folds or edges of the hanging sheet products toward a user for ease of grasping and quality of presentation purposes.
  • the support chute 4 thus provides an angled slide intercepting direct vertical hanging of the sheet products.
  • a user presses on the user interface ledge 27 or on the user interface ledge 28 with fingers, depending on whether a smaller or larger number of sheet products is required.
  • the user interface ledge 27 could be associated with a small food order and the user interface ledge 28 could be associated with a large food order.
  • further user interfaces could be provided to provide a greater range of numbers of sheet products that can be dispensed.
  • the moveable actuator part 19 moves linearly under direction of the user pressing on one of the user interface ledges 27, 28. Linear motion of the moveable actuator part 19 is converted to rotational motion of the roller 15 by way of the rack and pinion device.
  • the stack 10 is disposed in the housing 40 and rests against the distal and proximal shelves 21, 22.
  • a front face of the stack 10 curves partially around the roller 15 as a result of the relative positioning of the distal and proximal shelves 21, 22.
  • the roller 15 is pressed into the front face of the stack of sheet products to engage a front-most sheet product, rather than edges or folds which would be the case with engagement of the side faces of the stack. Rotation of the roller 15 causes the front-most sheet product of the stack 10 in engagement therewith to retract relative to the proximal shelf 22 in a manner that involves sliding against an underlying sheet in the stack.
  • the grip between the outer surface of roller 15 and the front-most sheet product is greater than a corresponding frictional force between the front sheet product and the underlying sheet product in the stack 10 so that it is able to be slid or moved relative thereto.
  • the sheet product will, in the illustrated gravity feed embodiment, fall from the proximal edge or fold into a hanging position extending through the dispensing opening 41.
  • a distal margin of the sheet product is not acted on by the roller 15 and thus remains pinched between the proximal shelf 21 and the remainder of the stack 10 to provide a suspension point allowing the sheet product to hang.
  • the above-described dispensing process will be repeated by rotation of the dispensing roller 15 by a different amount so that one or a plurality of sheet products is/are hanging through the dispensing opening 41, suspended at the distal shelf 21.
  • the hanging sheet products will lay to some extent on the underlying support chute 4, ready to be grasped by a user. A user may then reach in and grasp from both sides of the hanging sheet products, by making use of the cut-out 30 in the support chute 4, and pull them to release the hanging sheet products from the pinch at the distal shelf 21.
  • the sheet products can then be bagged or immediately used for wiping.
  • the hanging sheet products define a tail 44 that extends beyond the support chute 4. This may result from the use of the roller 15 in an interfolded sheet product arrangement.
  • an initial position of the tail 44 can be seen before the roller 15 has been operated to release the sheet product associated with the tail 44.
  • This tail 44 is not pinched at a distal margin between the remainder of the stack and the distal shelf 21, so that when the roller 15 is rotated, the tail 44 hangs beyond the folded sheet products that are still suspended at the distal shelf 21.
  • This tail 44 is folded behind the hanging sheet products by a user when grasping them, thereby making further use of the peripheral cut-out 30 of the support chute 44.
  • the cross-section of the roller 15 is generally circular, as shown in, for example, Figs. 4 and 7i.
  • Figs. 7a to 7h show yet further alternatives in which the cross-section is different from that of exemplary roller 15.
  • the profile of the roller includes fins, paddles or lobes. Between the fins, paddles or lobes are relatively recessed parts of the profile that will slip, e.g., slide or not contact, with respect to the front face of the stack 10.
  • the slip parts of the alternative roller designs allow a front-most sheet to be dispensed without disturbing a succeeding sheet, whereby the slip part of the roller is positioned in registration with the succeeding sheet. It is only when the roller is further rotated such that the next fin, paddle or lobe engages and grips the succeeding sheet, that a succeeding sheet begins to be dispensed.
  • An indexing system may be applied in association with non-circular alternatives of the roller, to promote an intended starting position for a particular fin, paddle or lobe thereby ensuring that the dispensing process selected by the user at the actuator 2 is properly implemented.
  • the non-symmetrical configuration of the roller designs of Figs. 7a to 7h include a particular starting position for the roller in the dispensing process of engaging, gripping and moving a front-most sheet of the stack 10 into the dispensing opening 41 as a result of a set amount of movement in the actuator 2.
  • An exemplary indexing system 45 is shown in Fig. 8 .
  • a cam wheel 46 is mounted to, and rotates with, the central shaft 14 of the roller.
  • the cam wheel 46 may be mounted on the other side of the support structure 12 to the actuator 2.
  • a cam follower 47 is urged by a torsion spring 49 onto an outer profile of the cam wheel 46.
  • the outer profile of the cam wheel 46 includes recessed portions 48 that are registered with starting or finishing points, as defined by at least one fin, paddle or lobe of the roller. In this way, if the dispensing cycle does not finish so as to eject a sheet product into the dispensing opening 41, the biasing force to which the cam followed 47 is subjected will tend to force or at least bias registration of the cam follower 47 and the recessed portion 48 of the cam wheel 46.
  • the indexing system 45 is able to complete this actuation stroke to ensure that the required number of sheet products is dispensed and to also ensure that the desired starting point for the roller in the dispensing cycle is provided for the next use.
  • a catch chute 50 is provided that is located between feet of the stand 5 and positioned so as to catch any sheet products that fall from the dispensing opening 41 and the support chute 4.
  • the catch chute 50 provides a sloped surface as a downward slide for any sheet products that have fallen, and also includes tabs 53 to stop movement of the fallen sheet products so as to hold them supported on the slide surface.
  • the catch chute 50 further comprises a recessed portion 51 that is generally centrally located and recessed relative to the slide surface of the catch chute 50 and which provides an opening at the tabs 53 to allow a user to grasp the sheet products from both faces.
  • Fig. 9 provides a further modification, which was mentioned as a possibility in the description above, of a further user interface ledge 52, so that a third, yet larger number of sheet products may be dispensed.
  • This embodiment has first, second and third user interface ledges 27, 28 and 52 for allowing a user to select between small, medium and large numbers of sheet products, which may correspond to small, medium and large food orders at, for example, a fast-food drive-through widow.
  • Each of the user interface ledges 27, 28 and 52 defines different stroke lengths for the moveable actuator part 19, which correspond to different respective amounts of rotation of the roller 15.
  • the first user interface ledge 27 could cause the roller 15 to rotate an amount sufficient to dispense one fold of interfolded sheet products, thereby providing two individual sheet products.
  • the second user interface ledge 28 could be associated with dispensing four individual sheet products and the third user interface ledge 52 could be associated with dispensing six individual sheet products.
  • the actuator is in the form of a geared rotation knob that meshes with a gear fixed to the central shaft 14 of the roller 15.
  • the actuator transmits rotational movement imparted by a user to cause rotational movement of the roller 15.
  • Fig. 11 shows another alternative embodiment for which there are provided three separate push buttons 61, 62, 63 that are moveable through the same actuation stroke, but respectively impart differing amounts of rotation on the roller 15 so as to cause different numbers of sheet products to be dispensed.
  • each of the push buttons 61, 62, 63 is respectively associated with a rack gear that engages a compound gear 65.
  • the compound gear 65 meshes with a gear 64 associated with the roller 15.
  • the compound gear 65 has gear components of different sizes respectively meshing with one of the rack gears associated with the push buttons 61, 62, 63.
  • the compound gear 65 thus transmits different amounts of rotation to the gear 64 so as to impart a different amounts of rotation to the roller 15 depending upon which of the push buttons 61, 62, 63 is pressed. Further, in the embodiment of Fig. 11 , the push buttons 61, 62, 63 are moved perpendicularly to the stacking direction, rather than parallel to the stacking direction as with the embodiments of Figs. 1 to 9 , to cause rotation of the roller 15.
  • FIG. 12 A yet further alternative embodiment of the actuator is shown in Fig. 12 .
  • the actuator includes three different push buttons 66, 67, 68 that impart different amounts of rotation to the roller 15 using the same stroke length.
  • a compound gear 69 is provided that has different gear size portions that mesh with sector gears 70, 71, 72, respectively associated with the first to third push buttons 66, 67, 68.
  • the stroke length associated with each of the push buttons 66, 67, 68 is the same, while respectively dispensing different numbers of sheet products, which is enabled by way of the compound gear 69 having differing gear size portions.
  • Fig. 12 the alternative embodiment of Fig.
  • each of the push buttons 66, 67, 68 moves along an arc, rotating about a pivot 73, in order to effect the dispensing process.
  • the various embodiments support linear motion along different axes, arc-like motion, and rotational motion for the user actuation interface.
  • Fig. 13 shows one exemplary modification not within the scope of the present invention in which the actuator includes an adjustable stop 75 allowing the start and finish point of the actuation stroke to be adjusted in order to calibrate the length of the actuation stroke to ensure the desired number of sheet products is dispensed.
  • different sheet properties such as calliper, embossing depth and/or maternal,
  • the actuator or the dispensing device may include an adjuster in order to compensate for changes in that relationship for different types of sheet product..
  • the stop 75 can be adjusted to shorten or increase the stroke length, thereby changing the amount of rotation of the dispensing roller for each of the user interface ledges 27, 28.
  • the actuator could be electronic.
  • an electric motor could be provided to turn the dispensing roller.
  • one or more actuation buttons could be utilized to dispense the desired number of sheet products.
  • respective control buttons could be provided that cause the electric motor to rotate the dispensing roller by a different amount in order to respectively dispense different numbers of sheet products.
  • the shelves 21, 22 are provided as plantar ledges, although alternative forms of the shelves are also contemplated.
  • a rod or rods could be used in place of the proximal shelf 22 and/or the distal shelf 21. Such a rod or rods would still be shelf-like and support a margin of the front face of the stack, allowing them to be described as shelves.
  • the roller 15 could be oriented in alignment with a short side of the stack, rather than with a long side of the stack.
  • the shelves 21, 22 could also be arranged at opposed short sides of the stack for contracting margins of the short sides of the front of the stack, rather than the long sides as shows.
  • Embodiments not within the scope of the present invention also contemplate an alternative dispensing process that obviates the user operating the actuator.
  • the user could simply grab the tail 44 to dispense the front-most sheet product.
  • the user grasping the tail 44 could dispenser a first number of sheet products (e.g., two) and the actuator may be configured to cause the dispensing member to dispense second and third greater numbers of sheet products (e.g., four and six, respectively).
