No. 4,416,392, U.S. Pat. No. 5,086,946, U.S. Pat. No. 4,653,666, EP 157 628 A1 and WO 03/002357 A1.
- the packaging of the dispenser and device is incorporated inside a pencil.
- the packaging of the dispenser is made out of one piece having a slot on the top of the piece, whereas in EP 157 628 the packaging of the dispenser is made out of a sheet or a plate which can be folded to construct a box-like structure for enclosing and surrounding the stack of sheet material.

- the present invention provides a dispenser device for holding and retaining a stack of sheets and for individually dispensing the sheets, wherein the sheets are arranged in a Z-fold manner within the stack, comprising a single dispenser platform having clamping means being integral with the dispenser platform for as well holding and clamping the stack in the dispenser apparatus.
- the present invention further provides a cover device for a file folder, a loose leaf, a book, a notebook, a file wrapper or the like, comprising at least one first cover sheet having at least one dispenser apparatus according to the present invention.
- the dispenser apparatus comprises on one hand a generally planar contact area for holding and carrying the stack.
- the dispenser apparatus comprises on the other hand at least two tongue-shaped devices for putting pressure on the top of the stack which is lying at least partially on the planar contact area.
- the contact area and the two tongue-shaped devices are arranged in such a way that the stack is clamped between those parts of the dispenser apparatus.
- the contact area and the two tongue-shaped devices of the dispenser apparatus therefore have a function of a clamping means. By clamping a stack between two tongue-shaped devices and a more or less planar contact area the stack is at least fixed within the dispenser apparatus.
- the contact area and the two tongue-shaped devices which are putting force or pressure on the top of the stack and thus are pressing the stack against the contact area advantageously allows dispensing a single sheet on top of the stack one after the other.
- the sheet on the top of the stack therefore can be easily removed out of the dispenser apparatus since the two tongue-shaped devices are impinging a force on the stack only at the end portions of the stack with the consequence that single sheets can be taken out of the dispenser apparatus one after the other.
- a particular advantage of the dispenser resides in the simplicity of the whole construction of the dispenser apparatus since it may be constructed only out of one single page, sheet, leaf, foil or the like comprising as well the contact area and the tongue-shaped devices for putting force or pressure on the top of the stack and clamping the stacks.
- a further advantage of the dispenser is the simplicity of its manufacturing process since only very simple process machines are necessary for making cuttings or slittings to create the contact area and the tongue-shaped devices. In a very simple process these features are just cut, punched, rotary-grinded and/or lasered out of a planar sheet-like base material. These process steps may also be applied for producing the other parts of the dispenser apparatus and especially to set the outer shape of the dispenser apparatus.
- a further advantage is the refillable functionality of the dispenser apparatus. If the dispenser apparatus is empty, that is, if the last sheet is withdrawn from the dispenser apparatus a new stack may be clamped between the contact area and the tongue-like apparatus. With this smart and useful functionality the dispenser apparatus does not have to be thrown away after it is empty.
- the dispenser apparatus consequently has a significantly longer life time. This is especially very attractive for those individuals who do not want to exchange the dispenser device after every stack especially for economic reasons.
- the stack contains a plurality of repositionable sheets wherein each sheet having a band coated (e.g. a narrow band) with a pressure sensitive adhesive layer on a back surface along one edge portion of the sheet by which the sheet is adhered together with a sheet below, with the sheets being stacked with a band of adhesive layers of adjacent sheets at alternating opposite edges of the stack, wherein removal of a first sheet withdraws one end of a second sheet below which then can be separated from the first sheet without withdrawing the second sheet.

Abstract
The present invention relates to a dispenser apparatus for holding and retaining a stack of sheets, such as notepapers or index flags, and for individually dispensing the sheets, wherein the sheets are arranged in a Z-fold manner within the stack, comprising a single dispenser platform having clamping means being part of the dispenser platform for as well holding and clamping the stack in the dispenser apparatus. The invention further relates to a cover device having such dispenser apparatus.
Description
- This application claims priority from European Application No. 05104056.6, filed May 13, 2005.
- The present invention relates to a dispenser apparatus for individually dispensing sheet material, such as notepaper or the like, wherein the sheet material is disposed in a Z-fold manner within the stack. The sheets having a band of adhesive layer coated on one surface along one edge by which the sheets are adhered together with the sheets being stacked with a band of adhesive of adjacent sheets at alternate opposite edges of the stack, wherein removal of one sheet withdraws one end of the next sheet which can be then separated without withdrawing the following sheet.
- The present invention in particular relates to sheets that can be adhered to and removed from a substrate such as written documents without damaging this substrate, wherein said sheets can have a portion coated with an adhesive layer to provide secure engagement with a substrate until it is intentionally removed. The adhesive layer comprises a repositionable adhesive, i.e. while the adhesive allows for the sheets to be sufficiently adhered such that they can withstand normal handling without being removed from the substrate, upon removal, the sheets do not destroy or damage the substrate, which may be for example a paper sheet.
- The present invention is further related to a cover device for a file folder, a loose leaf, a book, a notebook, a file wrapper or the like.
- In the course of reviewing and studying printed material it is common and convenient for individuals to write down short notes on a note paper and/or to use small flags to identify a position of a book or a file wrapper which is deemed to be important. Especially for locating passages within a book or a file wrapper often a search of several marked-up pages is required. One product that facilitates locating a particular page or a section of a page is a tape flag such as those manufactured by the 3M Company, St. Paul, Minn. under the trademark “Post-it®”. The material of these flags may be an elastic or flexible material, such as plastics, or a writeable sheet, such as paper.
- The prior art is provided with structures for the sheets adapted to mark positions of substrates such as written documents and dispenser packages for such sheets. Sheets from “Post-it®” note paper available from the 3M company are used extensively as such sheets and are particularly useful for that purpose because a repositionable pressure sensitive adhesive layer with which they are coated allows them to be placed and also to be removed from a document without damaging the document.
- It is known that a plurality of these flexible sheets having the same size are disposed in a stack and each of them comprising a layer of pressure sensitive adhesive on a back side of the sheet. The sheets have first and second ends and are adhered to each other within the stack with the first and second end of successive sheets in the stack and have first end portions adjacent their first ends that are not adhered to (or can be easily separated from) the underlying sheet in the stack to facilitate removal of the uppermost sheet in the stack. This arrangement of the sheet material or the note papers, respectively, disposed within a stack and adhered to each other with a releasable adhesive layer along alternating opposing edges is hereinafter referred to as an arrangement of sheet material in a so-called Z-fold manner.
- A typical manner of packaging this stack is to use a dispenser package for at least holding and covering the stack of sheets.
- U.S. Pat. No. 4,770,320 describes a dispenser package including such a stack of sheets—which is commercially available from 3M, St. Paul, Minn. under the trade designation “Post-it®” tape flags—wherein the layers of pressure sensitive adhesive extend only over a portion of the back sides of the sheets and wherein the single sheets are disposed within the stack in a Z-fold manner. The packaging dispenser has a box-like structure. For dispensing a single sheet or note paper, respectively, the housing of the dispenser package contains a slot on top of the dispenser package for dispensing one single sheet after the other through the slot.
- Various other dispenser packages containing and covering a stack of sheet material—such as the above-mentioned stack having Z-folded sheets—are widely known in the art, including WO 92/12072, WO 96/00659, EP 345 057 A1, U.S. Pat. No. 4,416,392, U.S. Pat. No. 5,086,946, U.S. Pat. No. 4,653,666, EP 157 628 A1 and WO 03/002357 A1.
- In WO 03/002357 the packaging of the dispenser and device is incorporated inside a pencil. In WO 96/00659, WO 92/12072, EP 345 057 A1 the packaging of the dispenser is made out of one piece having a slot on the top of the piece, whereas in EP 157 628 the packaging of the dispenser is made out of a sheet or a plate which can be folded to construct a box-like structure for enclosing and surrounding the stack of sheet material.
- In all above referenced applications the dispenser package forms a box-like structure in which the stack of sheet material is almost covered completely. This box-like package structure has the function to cover the stack and therefore to serve as a housing to prevent that the sheets are dispensed in an uncontrolled manner. Therefore, the box-like structure of the packaging not only holds and covers the stack but also surrounds the stack.
- The problem of nearly all dispenser package applications mentioned in the above reference documents is that the stack is surrounded completely and covered by a single-piece box-like housing structure. As a consequence of this it is not or at least with some effort possible to refill the dispenser apparatus if it is empty and if there is no sheet material left in the dispenser package. An empty dispenser apparatus is often not any more re-useable and, therefore, is thrown away. Furthermore, in case a sheet fails to dispense from such a closed dispenser, it is generally difficult or sometimes even impossible to restart the dispensing of sheets therefrom.
- Another problem being inherent to the dispensers referenced above is the more or less complicated fabrication and manufacturing of said devices. Especially, with the single-piece box-like housing structure of the dispenser it is rather difficult and complex and thus costly to fabricate the box like package having a slot for dispensing the sheet material on the top of the package. Especially, if the package is made of a coherent, non-detachable material, such as plastics, several process steps are necessary. In addition to that, more or less complex and thus expensive machines are necessary to fabricate the dispenser packages.
- It would now be desirable to provide a further dispenser device, in particular an improved dispenser device preferably having a construction as simple as possible. It would further be desirable to provide a dispenser device which can be fabricated in a more easy way. Furthermore, it would be desirable to provide a refillable dispenser device, wherein the refill process is as easy as possible. Desirably, the dispenser device can be readily combined or provided in for example a notebook.
- In accordance with the present invention, there is provided a dispenser apparatus having the features of claim 1 and/or a cover device having the features of
claim 11. - Accordingly, the present invention provides a dispenser device for holding and retaining a stack of sheets and for individually dispensing the sheets, wherein the sheets are arranged in a Z-fold manner within the stack, comprising a single dispenser platform having clamping means being integral with the dispenser platform for as well holding and clamping the stack in the dispenser apparatus.
- Accordingly, the present invention further provides a cover device for a file folder, a loose leaf, a book, a notebook, a file wrapper or the like, comprising at least one first cover sheet having at least one dispenser apparatus according to the present invention.
- In accordance with an embodiment of the invention, the dispenser apparatus comprises on one hand a generally planar contact area for holding and carrying the stack. In addition to that, the dispenser apparatus comprises on the other hand at least two tongue-shaped devices for putting pressure on the top of the stack which is lying at least partially on the planar contact area. In this dispenser apparatus the contact area and the two tongue-shaped devices are arranged in such a way that the stack is clamped between those parts of the dispenser apparatus. The contact area and the two tongue-shaped devices of the dispenser apparatus therefore have a function of a clamping means. By clamping a stack between two tongue-shaped devices and a more or less planar contact area the stack is at least fixed within the dispenser apparatus.
- It has thus been found that for implementing a simple and easy manufactured dispensing apparatus it is not necessary to cover the stack almost completely by means of a housing or the like. It is only necessary to provide a contact area to place the stack with its bottom portion on and to provide any means for exerting some force or pressure on top of the stack at opposite ends of the stack (i.e. the opposite ends between which the repositionable adhesive on the sheets of the stack alternate) in a way that the stack is fixed between the contact area and the means. With the dispenser apparatus according to the present invention the stack is not covered completely, but is fixed in a way that a movement of the stack is not possible at normal conditions when no force is impinged on the stack.
- However, the contact area and the two tongue-shaped devices which are putting force or pressure on the top of the stack and thus are pressing the stack against the contact area advantageously allows dispensing a single sheet on top of the stack one after the other. The sheet on the top of the stack therefore can be easily removed out of the dispenser apparatus since the two tongue-shaped devices are impinging a force on the stack only at the end portions of the stack with the consequence that single sheets can be taken out of the dispenser apparatus one after the other.
- A particular advantage of the dispenser resides in the simplicity of the whole construction of the dispenser apparatus since it may be constructed only out of one single page, sheet, leaf, foil or the like comprising as well the contact area and the tongue-shaped devices for putting force or pressure on the top of the stack and clamping the stacks.
- A further advantage of the dispenser is the simplicity of its manufacturing process since only very simple process machines are necessary for making cuttings or slittings to create the contact area and the tongue-shaped devices. In a very simple process these features are just cut, punched, rotary-grinded and/or lasered out of a planar sheet-like base material. These process steps may also be applied for producing the other parts of the dispenser apparatus and especially to set the outer shape of the dispenser apparatus.
- A further advantage is the refillable functionality of the dispenser apparatus. If the dispenser apparatus is empty, that is, if the last sheet is withdrawn from the dispenser apparatus a new stack may be clamped between the contact area and the tongue-like apparatus. With this smart and useful functionality the dispenser apparatus does not have to be thrown away after it is empty. Advantageously, the dispenser apparatus consequently has a significantly longer life time. This is especially very attractive for those individuals who do not want to exchange the dispenser device after every stack especially for economic reasons.

- Referring now to
FIG. 1 of the drawing, there is shown an exemplified embodiment of a single sheet of a stack according to the present invention generally designated by thereference numeral 10.FIG. 1 (a) shows a top view of the back side of thesheet 10 andFIG. 1 (b) shows a side view (b) of thesheet 10. - The
sheet 10 comprises an elongate preferably rectangular shape having afront side 11 and aback side 12 and first and second opposite ends 13, 14. Thesheet 10 typically comprises a single layer of transparent, semi-transparent or non-transparent flexible material. Thesheet 10 may be of any sheet material, such as paper, polymeric material or any other more or less flexible material. Thesheet 10 further can be designed to be a writeable note paper or an index for the marking of portions of documents (such as the “Post-it® Index” or the “Post-it® notes”). - The sheet thickness D5 depends on the sheet material and the desired application and is conveniently between 0.01 mm and 0.2 mm.
- The
sheet 10 further comprises acoating layer 15 on itsback side 12. Thecoating layer 15 comprises a repositionable pressure sensitive adhesive such as described for example in U.S. Pat. No. 3,691,140 and U.S. Pat. No. 4,166,152. Thecoating layer 15 is applied on asecond end portion 16 of theback side 12 adjacent thesecond end 14 while thesheet 10 is free of thecoating layer 15 of pressure sensitive adhesive as well at the wholefront side 11 surface and at afirst end portion 17 of thebackside 12 adjacent thefirst end 13. In the embodiment ofFIG. 1 the area of thefirst end portion 17 is smaller than the one of thesecond end portion 16. However, it may also be possible that both areas are equal in their size or thesecond end portion 16 is greater than thefirst end portion 17. - Generally, the width L1 of the
coating layer 15 is significantly smaller than the length L2 of saidsheet 10. - Referring now to
FIG. 2 of the drawing, there is shown an exemplified embodiment of a stack according to the present invention designated by thereference numeral 20.FIG. 2 shows three illustrations (FIG. 2 (a)-FIG. 2 (c)) of thestack 20 in different positions to illustrate the construction of thestack 20 as well as to illustrate the function of dispensing of asingle sheet 10. - The
stack 20 comprises a plurality (e.g. 10, 15, 50, 100, etc.) of flexible similar or equalsized sheets 10 such as those illustrated with respect toFIG. 1 . Thesheets 10 are disposed in alignment in thestack 20 with each of thesheets 10 having a top surface 11 (front side) and a bottom surface 12 (back side) and a more or less narrow band of athin coating layer 15 of pressure sensitive adhesive coated on thebottom surface 12 along oneedge portion 16 by which thesheet 10 is adhered to thetop surface 11 of anadjacent sheet 10 in the stack. Thesingle sheets 10 are stacked with theircoating layers 15 to twoadjacent sheets 10 at alternateopposite sides stack 20. In this arrangement thesheets 10 are arranged within thestack 20 in a Z-fold manner. Thebottom sheet 23 typically does not comprise acoating layer 15 such as thesheets 10 arranged above thebottom sheet 23. -
FIG. 3 shows in a top view a first application of a dispenser apparatus according to the present invention. The dispenser apparatus is referenced byreference numeral 30. In the embodiment inFIG. 3 thedispenser apparatus 30 is shown without astack 20.FIG. 4 shows a perspective view of thedispenser apparatus 30 ofFIG. 3 for dispensing single sheets out of a stack carried by elements of thedispenser apparatus 30. - The
dispenser apparatus 30 is made out of a generallyflexible sheet material 31, for example plastic, hereinafter referred to asdispenser platform 31. The thickness of thedispenser platform 31 is referenced by the reference numeral D1 inFIG. 4 . It is generally desirable for the functionality of thedispenser apparatus 30 that the material of thedispenser platform 31 is generally elastic or resilient which allows parts of thedispenser apparatus 30 to be elastically deformed. It is further desirable that after deformation of thedispenser platform 31 or parts thereof these parts return to at least in part to their original position. The material of thedispenser platform 31 may be a polymeric material such as polypropylene, polyester and the like. - The
dispenser apparatus 30 comprises two (first) tongue-shapeddevices 32 being connected with thedispenser platform 31. In the embodiment as shown inFIG. 3, 4 the tongue-shapeddevices 32 have (but not necessarily) a rectangular shape wherein each of the tongue-shaped devices have afront end side 33, twolateral sides back end side 36. The two tongue-shapeddevices 32 are arranged within thedispenser platform 31 such that their two front end sides 33 are faced vis-A-vis each other but are distanced from each other. The distance between the two front end sides 33 is referenced by the reference numeral D2 inFIG. 3 . - Both tongue-shaped
devices 32 are connected to thedispenser platform 31 at their respective back end sides 33 for example by means of a folding line 33 (dotted line inFIG. 3 ). The other sides 33-35 of the tongue-shapeddevices 32 are not connected to thedispenser platform 31. Typically, there are a more or less wide slits (not shown inFIG. 3, 4 ) between the tongue-shapeddevices 32 and the surrounding portions of thedispenser platform 31. In a preferred method of producing the tongue-shapeddevices 32 the slits are cut, punched, lasered or the like. - The
dispenser apparatus 30 further comprises a (generally planar)contact portion 37 for bearing and carrying thestack 20 of sheet material. Thiscontact portion 37 is a integral part of thedispenser platform 31. Thecontact portion 37 is formed on the one hand by a bridge-like structure 38. The bridge-like structure 38 is defined by those parts of thedispenser platform 31 being arranged right between two adjacent tongue-shapeddevices 32. Additionally, thecontact portion 37 may be formed on the other hand by thoseparts 39 of thedispenser platform 31 which are basically arranged adjacent to the lateral sides 34, 35 of a respective tongue-shapeddevice 32. In general, in the embodiment illustrated inFIG. 4 thecontact portion 37 is formed by thoseportions dispenser platform 31 bearing or carrying the bottom part of thestack 20. - Typically, the width L3 of a stack 20 (see
FIG. 1 ) is smaller than the length D3 (seeFIG. 3 ) of the front end side of the respective tongue-shapeddevices 32. In this case, when astack 20 is clamped between the tongue-shapeddevices 32 and the remaining parts of thedispenser platform 31 thestack 20 is being carried only by the bridge likestructure 38. Therefore, in this case thecontact portion 37 consists of the bridge likestructure 38 only. - However, the
dispenser apparatus 30 according to the present invention is not limited to this application. Especially, the functionality of thedispenser apparatus 30 is also fulfilled if the width L3 of astack 20 is greater than the length D3 of the front end side of the tongue-shapeddevices 32; that is in other words, if the width L3 of thestack 20 is wider than the width D3 of atongue 32. In this case, when astack 20 is clamped between the tongue-shapeddevices 32 and the remaining parts of thedispenser platform 31 thestack 20 is laterally overlappingparts 39 of thedispenser platform 31. Theselateral parts 39, which are arranged lateral to the lateral sides 34, 35 of the tongue-shapeddevices 32 then also have the function of bearing and carrying the clampedstack 20. Therefore, in this case theseparts 39 together with the bridge likestructure 38 are part of thecontact portion 37. - The functionality of the
dispenser apparatus 30 is hereinafter described with respect toFIGS. 3 and 4 . - In the starting position when the
dispenser apparatus 30 is empty it does not contain anystack 20 of sheet material. In this empty state thedispenser platform 31 of thedispenser apparatus 30 forms a basically flat, planar surface wherein thecontact portion 37 as well as the tongue-shapeddevices 32 are arranged more or less in the same plane. Thedispenser apparatus 30 according to the present invention contains a fillable and/or refillable functionality. For this the both tongue-shapeddevices 32 are lift off from thedispenser platform 31 in directions X, Y as shown inFIG. 4 , whereas the back end side 36 (or the respective fold line) represents the axis the both tongue-shapeddevices 32 are moved around. By lifting of the tongue-shapeddevices 32 it is possible to place and position astack 20 on top of thecontact portions 37 provided for this. Afterward the tongue-shapeddevices 32 may be released. Since the material of thedispenser platform 31 is elastic the tongue-shapeddevices 32 at least partially get in contact with the top of thestack 20 and thus exert some pressure on the top of thestack 20. Consequently, thestack 20 is clamped and fixed between the both tongue-shapeddevices 32 and thecontact portion 37 such that a lateral movement and or a vertical movement of thestack 20 is not possible (i.e. under normal conditions where there is no great lateral or vertical pressure put on the clamped stack 20). - For achieving the dispensing functionality of the
dispenser apparatus 30 it is necessary that thesheet 10′ on top ofstack 20 is positioned such that after release of the tongue-shaped devices 32 afree end 40 of thissheet 10′ is sticking out of anopening 41 of thedispenser apparatus 30. When thisfree end 40 is grasped and pulled in a direction Z to dispense thesheet 10′ its coating layer (not shown inFIG. 4 ) pulls the adjacent free edge of thenext sheet 10″ below thetop sheet 10′ from thestack 20 and brings this adjacent free edge of the next sheet through the opening 42. Upon withdrawing the entiretop sheet 10′ and the free edge of thenext sheet 10″ through theopening 41 thetop sheet 10′ is separated from thenext sheet 10″ by peeling the twosheets 10′, 10″ apart. Thetop sheet 10′ and itscoating layer 15 are released from thenext sheet 10″. Thetop sheet 10″ has now a free edge (not shown inFIG. 4 ) extending from theopening 41 of thedispenser apparatus 30 so it may be readily grasped for use, and upon doing so, the other edge of thenext sheet 10″ will be withdrawn from thedispenser apparatus 30 through theopening 41 and so on until the last sheet of thestack 20 is withdrawn. - At the beginning the
stack 20 has a stack thickness D4. By withdrawingsheets 10′, 10″ through theopening 41 of thedispenser apparatus 30 the stack thickness D4 decreases. However, although the stack thickness D4 decreases thestack 20 is well positioned and fixed within thedispenser apparatus 30 since the elastic tongue-shapeddevices 32 follow the decreasingstack 20 and thus continue to put pressure on top of thestack 20 i.e. atthick stacks 20 as well as atthinner stacks 20. That means that the stack thickness D4 advantageously does not affect the functionality of thedispenser apparatus 30. Consequently, thedispenser apparatus 30 is not restricted (of course within a given range) to a specific number ofsheets 10 within thestack 20. This opens a rather wide range of applications of thedispenser apparatus 30 according to the present invention. - At this point it is necessary to mention that for the function of the
dispenser apparatus 30 in the basic application according toFIG. 3 and 4 it is not important whether the tongue-shapeddevices 32 are lift-off in the directions X, Y or lift down directly opposed to these directions X, Y. - The length of a
front end side 33 of the tongue-shapeddevice 32 is referenced by the reference numeral D3 inFIG. 3 . Preferably, thestack 20 clamped between thecontact portion device 32 has a width L3 (seeFIG. 1 ) being equal or smaller than the length D3 of the front end side 33 (i.e. L3≦D3). However, it shall be understood that thedispenser apparatus 30 is also working if the length L3 is greater than the length L3 (i.e. L3>D3). - Referring now to
FIG. 5 of the drawing, there is shown a second embodiment of a dispenser apparatus.FIG. 5 shows the dispenser apparatus in a top view. - Different to the
dispenser apparatus 30 thedispenser apparatus 50 in FIG. S additionally comprises two second tongue-shapeddevices 51 each being assigned to a first tongue-shapeddevice 32. In the embodiment inFIG. 5 , both second tongue-shaped devices 51 (typically but not necessarily) have a rectangular shape each having afront end side 52, twolateral sides back end side 55. The two tongue-shapeddevices 51 each are connected to adispenser platform 31′ at their respective back end sides 55 for example by means of a fold line 55 (dotted line inFIG. 5 ). The other sides 52-54 of the second tongue-shapeddevices 32 are not connected to thedispenser platform 31′. - The two second tongue-shaped
devices 51 are arranged within thedispenser platform 31′ such that the two front end sides 52 quasi extend into the respective tongue-shapeddevice 32 such that the second tongue-shapeddevices 51 are at least partially arranged inside the first tongue-shapeddevices 32. The fold line of the second tongue-shapeddevices 51 are preferably (but not necessarily) arranged outside the first tongue-shapeddevices 32. Typically, both second tongue-shapeddevices 51 have a similar shape compared to the first tongue-shapeddevices 32, however, both second tongue-shapeddevices 51 are smaller than the respective ones of the first tongue-shapeddevices 32. - The second tongue-shaped
devices 51 forms part of thecontact portion 37 and thus has the function of carrying thestack 20. The second tongue-shapeddevices 51 additionally act as a stopping point such as to prevent thestack 20 sliding through the portions of thedispenser platform 31′ after being clamped between the first tongue-shapeddevices 32 and thecontact area 37. - In
FIG. 5 only one single second tongue-shapeddevice 51 assigned to each one of the first tongue-shapeddevices 32 is shown, however, it shall be understood that also more than one second tongue-shapeddevices 51 may be assigned to each one of the first tongue-shapeddevices 32, typically depending on the width L3 of astack 20 and/or the length D3 of a front side of the first tongue-shapedapparatus 32. - The
dispenser apparatus 50 inFIG. 5 further comprises several more or less round or oval holes 5, 7 at each end of the slits of the tongue-shapeddevices devices -
FIG. 6 shows in a top view a first application for adispenser apparatus 50, e.g. such as the one shown inFIG. 5 . Thedispenser apparatus 50 inFIG. 6 shows acover 60 having twocover sides fold line 63. Thecover 60 is suitable for holding a plurality of documents, a folder, a file wrapper, a ring binder, a book or the like. - One
cover side 61 of thecover 60 according to the present invention contains in this embodiment threedispenser apparatuses 50, e.g. such as the ones shown inFIG. 5 . In the embodiment inFIG. 6 thedispenser apparatus 50 each have a different size and are therefore suitable for carryingstacks 20 of sheet material having different lateral size. -
FIG. 7 shows in a top view a second application of a dispenser apparatus.FIG. 7 shows asingle sheet 70, e.g. for use in a ring binder, a file folder or the like and havingholes 71 at oneedge side 72 of thesheet 70. Similar to the first application shown inFIG. 6 thesheet 70 comprises threedispenser apparatuses 50 of different size. -
FIG. 8 shows in a top view a further application of adispenser apparatus 80, e.g. such as the one shown inFIG. 5 .FIG. 8 shows acover 80 for a folder, a file wrapper, a ring binder, a book or the like. Thecover 80 inFIG. 8 comprises basically four cover sides 81-84 being connected at least to one adjacent cover side 81-84 by means of fold lines 85-87. In the embodiment inFIG. 8 only one cover side 81 contains twodispenser apparatus 50 according to the present invention having the same size. This cover side 81 is arranged at the outer part on the left side of thecover 80. - In addition to the two
dispenser apparatus 50 this cover side 81 contains further means for collecting other dispenser apparatus or utensils. These further means which hereinafter are not described in more detail are designated inFIG. 8 byreference numeral 88. - In the embodiment shown in
FIG. 8 the single cover sides 81-84 of thecover 80 are provided to be turned down using the fold lines 85-87. By doing this the cover side 81 can be clapped on top of thecover side 82 using thefold line 85 and thecover side 84 can be clapped on top of thecover side 83 using thefold line 87. Thecover 80 further contains means for fixing each of the twocover sides 81, 82 and the cover sides 83, 84, respectively. To perform the fixing the cover side 81 contains on itslateral edges 92 three tuck-in flaps 89. These tuck-inflaps 89 are used for inserting in respective recess means 90 provided in thecover side 82. These recess means 90 are provided byslots 90. Theseslots 90 are arranged inflaps 91 atlateral edges 93 of thecover side 82. Theflaps 91 are connected with thesingle cover side 82 next to the cover side 81. If the cover side 81 is clapped on top of thecover side 82 theflaps 91 may be clapped on their part on top of the cover side 81. In this arrangement the tuck-inflaps 89 can be inserted in theslots 90 of theflaps 91, thereby fixing the twocover sides 81, 82 to each other. - The other cover sides 83, 84 also contain respective tuck-in
flaps 89, recess means 90 and flaps 91 to fix the twocover sides - The so-constructed
cover 80 may then be used for a ring binder, a writing pad, a book or the like whereas the front side and the back side of these tools each may be stuck between two fixed cover sides 81, 82 and 83, 84, respectively. Especially, when using a writing pad or a ring binder these tools gain a new functionality since in addition to their typical functionality with the new implementation havingdispenser apparatus 50 according to the present invention the user now has a possibility also to use notes for writing down short messages or use index flags for marking several pages within the writing pad, the ring binder or any other book or document. - If the used writing pad or the ring binder inside the
cover 80 is empty, that is if there is no more paper within the writing pad or the ring binder, thecover 80 may be easily removed and can be used for a new writing pad or ring binder. - Another aspect of this improved application in
FIG. 8 is that thecover 80 according to the present invention is also suitable for upgrading the appearance of a normal ring binder, writing pad, file wrapper or the like. - Above, embodiments of the dispenser apparatus and especially embodiments of covers having those dispenser apparatuses have been described. However, this should be seen as merely non-limiting examples. Many modifications are possible within the scope of the invention as defined in the claims and the description without deviating from the scope of the present invention.
