- Folding devices such as boards or plates, have long been used to longitudinally fold webs and other sheet-like materials in order to form a stack of folded sheets. The sheets are, generally speaking, drawn over the folding device wherein the shape and configuration of the device causes the sheet to twist and bend thereby producing the desired fold.
- Folding devices have heretofore been provided in a variety of shapes and configurations in order to achieve the desired fold lines and folding patterns. Folding devices have been used to form a number of different folds including, for example, half-folds, quarter folds, c-folds, v-folds, j-folds, w-folds, z-folds, and so forth.
- folding boards have also been used in series to achieve inter-folded or inter-leafed sheets, that is to say sheets folded such that they partially envelope portions of another sheet.
- Inter-leafed sheets are commonly employed in stacks as a mechanism to facilitate removal of the individual sheets from a dispenser. Withdrawal of a first sheet through a dispenser opening pulls the enveloped portion of a second sheet through the dispenser opening such that it extends out of the dispenser opening and is exposed. Having a portion of the subsequent sheet extending out of the dispenser opening greatly facilitates removal of the same from the dispenser by the user.
- the housing 14 may be made from numerous materials and by numerous methods known to those skilled in the art.

- the openings in the cartridge described above can be formed by removal of removable portions that may either be removed (or simply not formed) during manufacture of the cartridge or removed just prior to installation of the cartridge in the housing. If the removable portions are to be removed as part of the manufacturing process, the cartridge should be shipped to the user wrapped, for example in a polyethylene bag, to preserve the sterility of the paper products in the cartridge. If the removable portions are to be removed as part of the installation process, the edges of the removable portions should be weakened, scored, etc. for easy removal.
- the cartridge 70 is desirably made of heavy paper or cardboard, but may be made of any other suitable material known to those skilled in the art such as, for example, durable plastic films and so forth.
- the member 100 is shown having a first portion 104 extending into the interior area 32 of the housing 14 .
- the first portion 104 of the member 100 engages and applies force to the paper products 12 .

- the first portion 104 extends from about 1 ⁇ 3 to about 1 ⁇ 2 of the way across the width of the interior area 32 of the housing 14 .
- the first portion 104 of the member 100 should be sufficiently sturdy to withstand substantial deflection from application of force against the paper products 12 .
- the member 100 further includes a second portion 106 disposed substantially within the slot 60 in the sidewall of the housing 14 .
- the second portion 106 of the member 100 is attached to a moveable slide 107 disposed within a track 108 .
- the cross-sectional area of the slide 107 is slightly smaller than the cross-sectional area of the track 108 to allow for free movement of the slide within the track.
- the slide 107 is also sufficiently long to substantially reduce and/or eliminate rocking within the track 108 that would inhibit free movement.
- the track 108 is defined within a track housing 110 .
- the track housing 110 is external to the sidewalls of the housing 14 .
- the track housing 110 is be attached to the sidewall over the slot 60 by any of a variety of ways known to those skilled in the art including, but not limited to, using adhesives, screws, nuts and bolts, and/or nails, and so forth.
- Force is applied to the slide 107 in the dispensing direction 62 by a spring 102 disposed within the track 108 .
- the slide 107 and the spring 102 move within the track 108 , but are constrained from falling out of the track because the slot 60 in the side wall of the housing 14 is narrower than the slide and the spring. Because the spring 102 is compressed within the track 108 , the spring 102 urges the slide 107 and the attached member 100 in the dispensing direction 62 .
- the extension force of the spring acting on the member urges the paper products 12 toward the dispensing opening 40 .
- the member 100 extends through the cartridge slot 88 (shown in FIG. 4) to engage the paper products 12 .
- Use of the spring mechanism described above allows the container 10 to be used in those situations where paper products are to be dispensed in a substantially horizontal or upward direction, i.e., where the paper products will not be urged towards the dispensing opening by the force of gravity.
- the spring 102 is sized to provide sufficient force to urge the paper products 12 to the dispensing opening 40 .
- the spring 102 applies substantially constant pressure against the paper products 12 at all positions of travel. Application of substantially constant pressure helps to prevent over-application of force when the member 100 is towards the end wall 20 of the housing 14 and under-application of force when the member is closer to the dispenser opening 40 .
Abstract
Description
- Various types of dispensers for paper products have been developed to provide ready availability of the paper products to users. Such dispensers are often provided in public places such as restaurants or rest rooms where customers remove from the dispenser a desired amount of paper products for personal use. In some high traffic areas, such as fast food restaurants, a large number of customers may use a paper product dispenser such as a napkin dispenser in a short period of time. Therefore, dispensers have been developed that hold a large number of paper products for use by a large number of consumers.
- For many applications, it is desirable to have a large dispenser that will function well in a horizontal position as well as a vertical position. This is particularly desirable when there is limited vertical space available. Unfortunately, large horizontal dispensers are subject to a number of drawbacks. First, because access to the body of the dispenser may be limited by structures such as counters or cupboards surrounding the dispenser, it can be difficult to load large quantities of napkins into a large dispenser. Second, if paper products are not properly loaded into the dispenser, the paper products may jam as they are removed thereby preventing further removal of paper products by users. Third, a person refilling a large dispenser is more likely, due to the larger number of paper products involved, to drop some of the paper products onto a floor. Any dropped paper products are then unsanitary and must be discarded, thereby creating more waste and defeating certain benefits of the larger dispenser. Fourth, lacking an assist from gravity, horizontal dispensers require an external force to move the paper products through the dispenser.
- Therefore, there is a need for large dispensers, both horizontal and vertical, that reduce the incidence of waste of paper products due to dropping of the paper products during refilling of the container. There is likewise a need for such dispensers that reduce the incidence of jamming of paper products and the resultant inability to dispense further paper products, and further that have a mechanism for moving the paper products toward the dispenser opening so that individual paper products are readily removed.
- The present invention will be more fully understood from the following detailed description, taken in conjunction with the accompanying drawings (not to scale), wherein like reference numerals refer to like parts, and in which:
- FIG. 1 is a perspective view of an exemplary container for dispensing paper products that contains a cartridge filled with paper products;
- FIG. 2 is a perspective view of the empty container of FIG. 1;
- FIG. 3 is an exploded perspective view of the container and cartridge of FIG. 2 with the cartridge being inserted into the container;
- FIG. 4 is a perspective back view of an exemplary cartridge;
- FIG. 5 is a cross-sectional view of the container of FIG. 1 taken along line1-1 of FIG. 1; and
- FIG. 6 is a perspective view of an exemplary force-applying mechanism for use with the container and cartridge of FIG. 1.
- Reference will now be made in detail to various embodiments of the invention, one or more examples of which are illustrated in the drawings (not to scale). Each example is provided by way of explanation of the invention and not meant as a limitation of the invention. For example, features illustrated or described as part of one embodiment or figure can be used on another embodiment or figure to yield yet another embodiment. It is intended that the present invention include such modifications and variations.
- The present invention is directed to a container for dispensing sheet-like materials. Various sheet-like materials can be dispensed from the container of the present invention such as, for example, paper, nonwoven, and other products. Exemplary sheet-like products include, but are not limited to, facial tissue, towels, bathroom tissue, wipers, napkins, seat covers and so forth. The specific composition of the sheet materials dispensed can vary as desired. Exemplary sheet-like materials and methods of making the same include, but are not limited to, those described in U.S. Pat. Nos. 3,301,746; 3,322,617; 3,650,882; 4,100,324; 4,436,780; 4,659,609; 4,737,393; 5,048,589; 5,284,703; 5,399,412; 5,494,554; 5,607,551; 5,672,248; 5,716,691; 5,772,845; 5,776,306; 6,077,590; 6,273,996; 6,096,152 and so forth. While paper products are generally discussed with regard to the embodiments described herein below, it will be understood that various other products could be substituted therefore.
- The container of the present invention can hold and dispense significant numbers of individual sheets. Desirably, the container is sized to hold and dispense at least about 250 sheets. By way of example, the container can contain between about 400 and about 1000 sheets. In certain embodiments, the container can contain and dispense between about 700 and about 900 sheets.
- Referring to FIG. 1, a
container 10 is disclosed for dispensingpaper products 12. Thecontainer 10 includes ahousing 14 in which thepaper products 12 are placed and from which thepaper products 12 are dispensed in a dispensingdirection 62. Optionally, thepaper products 12 may be contained within a cartridge which is placed within thehousing 14. The container can be positioned in a vertical or horizontal orientation either alone or within a supporting structure or surface. - The
housing 14 includes anend wall 20 and a number of side walls including afirst side wall 22, asecond side wall 24, athird side wall 26, and afourth side wall 28 for housing thepaper products 12. Theside walls end wall 20 to define an interior surface 30 (see FIG. 2) ofhousing 14, within which an interior area 32 (see FIG. 2) is located. Theside walls housing 14. Theside walls end wall 20 may each, if desired, be made of two or more planar portions. Such construction strengthens thehousing 14 and is useful in locations where the housing might be vandalized. The outer portions of theside walls housing 14 to prevent destruction of the housing, removal of the housing from its mounting, or removal ofpaper products 12 from the housing. - The
container 10 further includes adoor 34 which is removably or hingedly attached to one of theside walls door 34 may be attached to one of theside walls more hinges 46. Thedoor 34 is openable for insertion ofpaper products 12 into the interior area of thehousing 14 when the supply ofpaper products 12 is depleted and/or runs low. - Desirably, the
door 34 includes one ormore fasteners 36 that releasably hold the door closed. As used herein, the term “fasteners” means devices that fasten, join, connect, secure, hold, or clamp components together. Fasteners include, but are not limited to, hooks, hook and eye fasteners, latches, snaps, snap-fits, clips, clasps, loop fasteners, interlocking male/female connectors, fishhook connectors, and so forth. Thefastener 36 is openable when desired to reopen thedoor 34. In one embodiment, the fastener 36 pivots from apivot point 38. Alternatively, thefastener 36 may be made of a resilient material that is bendable to release thedoor 34. Many other types of suitable releasable fasteners are known to those skilled in the art. - The
door 34 further defines a dispensing opening 40 through which thepaper products 12 pass as they are dispensed. - Optionally, one or more protrusions may extend into the interior area of the housing. In one embodiment, as partially shown in FIG. 2, the
second side wall 24 and thefourth side wall 28 includeprotrusions 42 extending into the interior area of thehousing 14. However, theprotrusions 42 could be disposed on any of the walls and one wall can have multiple protrusions. In those embodiments wherein pairs of protrusions are disposed on opposing walls of thehousing 14, they can be disposed at the same height or different heights (i.e., staggered). Theprotrusions 42 desirably comprise a generally downwardly angled structure and can have a geometric and/or curvilinear structure. By way of example only, the protrusions can comprise curved bumpers that may include a plurality of ridges extending across the curved bumpers perpendicular to the dispensing direction. Theprotrusions 42 extend into theinterior area 32 to contactpaper products 12 and thereby oppose the movement ofpaper products 12 in the dispensing direction. By extending into theinterior area 32 to contactpaper products 12, theprotrusions 42 impede the movement ofpaper products 12 toward the dispensing opening, but do not prohibit such movement. The use of protrusions to control dispensing is described, for example, in U.S. Pat. No. 6,241,118 to Tramontina and U.S. Pat. No. 6,378,726 to Chan et al., the entire contents of which are incorporated herein by reference. - As noted above, the
door 34 may be hingedly attached to one of theside walls door 34 is openable for insertion ofpaper products 12 into theinterior area 32 of thehousing 14 when the supply of paper products is depleted and/or runs low. Thefastener 36 that holds thedoor 34 closed may, for example, include interlockingtabs 48. The interlockingtabs 48 are movable when desired to reopen thedoor 34. In one embodiment, the interlockingtabs 48 are movable by pressing an attachedbutton 49 or other actuating mechanism. Any other type offastener 36 known to those skilled in the art for reopenably securing thedoor 34 may be used. - Desirably, the
door 34 further includes one ormore control ribs 52 that extend into theinterior area 32 to contact paper products when the door is in the closed position. Thecontrol ribs 52 space, slow, align, and/or support paper products as the same are moved toward thedoor 34 and through the dispensingopening 40. Size, shape, and spacing of the control ribs can be used to control dispensing of the paper products. Thecontrol ribs 52 may have different dimensions to properly support and guide the paper products into the dispensingopening 40. For example, atall rib member 56 extends into theinterior area 32 by a greater amount than ashort rib member 58. Thetall rib members 56 andshort rib members 58 are illustrated to show an exemplary dispensing configuration. As one example, thetall rib member 56 may have a height ranging from about 1 to about 2 inches at the location where it intersects with thethird side wall 26 and an offset or height ranging from about 0.1 to about 0.5 inch adjacent the dispensingopening 40. Theshort rib member 58 may have a height ranging from about 0.5 to about 1.5 inch at the location where it intersects with thefirst side wall 22 and an offset or height ranging from 0 to about 0.25 inch adjacent the dispensingopening 40. The rib members may have various widths or thicknesses and the width of a rib member may vary along any dimension or dimensions. Desirably, the portion of the rib member contacting the paper product will be relatively thin and smooth to minimize friction. The use of rib members is further described in U.S. Pat. No. 6,241,118 to Tramontina and PCT Publication WO 99/30601, the entire contents of which are incorporated herein by reference. - The
container 10 further includes a means for urgingpaper products 50 toward the dispensingopening 40 in thedoor 34. Various alternatives are possible within the scope of the invention to urge paper products toward thedoor 34. The means for urgingpaper products 50 may comprise any structure that allows paper products to be urged towards and dispensed from the dispensingopening 40 in thedoor 34. In one embodiment, the means for urgingpaper products 50 includes amember 100 that extends through aslot 60 in thethird sidewall 26 of thehousing 14. As discussed more fully below in conjunction with FIGS. 5 and 6, themember 100 is engaged to a spring which, when compressed, applies force to the member in the dispensingdirection 62. Themember 100, in turn, applies an urging force to the stack of paper products. - The dispensing
opening 40 may have many shapes within the scope of the present invention, as long as the opening provides easy access for a user. Optionally, the dispensing opening may also be configured to provide metered delivery of individual paper products. Desirably, the paper products are interfolded, tabbed, or tab interfolded to provide metered feeding of individual paper products one at a time. Folding devices, such as boards or plates, have long been used to longitudinally fold webs and other sheet-like materials in order to form a stack of folded sheets. The sheets are, generally speaking, drawn over the folding device wherein the shape and configuration of the device causes the sheet to twist and bend thereby producing the desired fold. Folding devices have heretofore been provided in a variety of shapes and configurations in order to achieve the desired fold lines and folding patterns. Folding devices have been used to form a number of different folds including, for example, half-folds, quarter folds, c-folds, v-folds, j-folds, w-folds, z-folds, and so forth. - In addition, for more complex folds requiring multiple fold lines, it is known to form the necessary fold lines using two or more folding devices in series. In this regard, folding boards have also been used in series to achieve inter-folded or inter-leafed sheets, that is to say sheets folded such that they partially envelope portions of another sheet. Inter-leafed sheets are commonly employed in stacks as a mechanism to facilitate removal of the individual sheets from a dispenser. Withdrawal of a first sheet through a dispenser opening pulls the enveloped portion of a second sheet through the dispenser opening such that it extends out of the dispenser opening and is exposed. Having a portion of the subsequent sheet extending out of the dispenser opening greatly facilitates removal of the same from the dispenser by the user. By way of example only, various folding devices, folding patterns and inter-folding schemes are described in the following U.S. Pat. Nos. 3,401,928; 3,679,094; 3,817,514; 3,841,620; 4,131,271; 4,502,675; 5,868,276; 6,045,002; and 6,168,848. However, the present invention does not require the use of interfolded paper products.
- The
housing 14 may be made from numerous materials and by numerous methods known to those skilled in the art. Thehousing 14 may be made of plastic such as polyethylene, nylon, and so forth. However, other suitable materials, such as other plastics or metals, may be provided for any or all of the parts of thehousing 14. As one example, thehousing 14 may be made of an injection-molded plastic. Theprotrusions 42 andcontrol ribs 52 are desirably formed integral with thehousing 14. However, theprotrusions 42 andcontrol ribs 52 may be formed separately from thehousing 14 and attached later. Also, theprotrusions 42 andcontrol ribs 52 may be made of different material from thehousing 14 if desired. For example, theprotrusions 42 andcontrol ribs 52 may be made of a more resilient material than the materials described above, such as an elastomer or rubber. - Desirably, as mentioned above, a cartridge may be provided for holding paper products to be dispensed to a user. As shown in FIG. 3, a
cartridge 70 havingoutside walls 72 is provided for insertion into theinterior area 32 of thehousing 14 for containing paper products to be dispensed. The cartridge has abottom end 74 that is adapted to dispense paper products. Opposing thebottom end 74 is atop end 76. Thecartridge 70 is sized to fit within theinterior area 32 of thehousing 14. Desirably, thecartridge 70 is sized to be only slightly smaller than thehousing 14 to maximize the number ofpaper products 12 contained within the cartridge. If thehousing 14 includes a partial side wall, the cartridge should be large enough to prevent the cartridge from falling from the opening in thehousing 14. - The
cartridge 70 can hold and dispense significant numbers of individual sheets. Desirably, thecartridge 70 is sized to hold and dispense at least about 250 sheets. By way of example, thecartridge 70 can contain between about 400 and about 1000 sheets. In certain embodiments, thecartridge 70 can contain and dispense between about 700 and about 900 sheets. - The cartridge includes a plurality of openings. The
bottom end 74 of thecartridge 70 has anopening 94 corresponding to the dispensingopening 40 through whichpaper products 12 are dispensed. Additionally, one ormore openings 90 corresponding to thecontrol ribs 52 may be at thebottom end 74 of thecartridge 70. Thecontrol ribs 52 extend through theopenings 90 to support and/or align thepaper products 12 for dispensing through the dispensingopening 40. - To permit visual inspection of the amount of paper products remaining in the
cartridge 70, thecartridge 10 may define at least oneadditional opening 96 in one of the cartridge outsidewalls 72. The contents of thecartridge 70 are visible through theopening 96. Desirably, at least onesuch opening 96 is visible from outside thecontainer 10. Two ormore openings 96 may be provided in a single wall to provide a greater range of visual inspection. - FIG. 4 is a perspective view showing the
cartridge 70 fully inserted into thehousing 14 mounted in the countertop 16. - As noted above, the cartridge includes a plurality of openings through the cartridge. One such opening is a
slot 88 through which extends the means for urgingpaper products 50 when thecartridge 70 is loaded into thehousing 14. Theslot 88 is disposed at one of theoutside walls 72 of thecartridge 70. Alternatively, theslot 88 may extend around thetop end 76 of thecartridge 70 to allow the means for urgingpaper products 50 to be received by thetop end 76 of the cartridge. - Optionally, the
cartridge 70 may include one or more of anotheropening 92 that corresponds to theoptional protrusions 42 in thehousing 14. Theopenings 92 are disposed in theoutside walls 72 of thecartridge 70 so that theopenings 92 can encompass and receive theprotrusions 42 extending from the interior surface 30 of thehousing 14. Thus, upon placement of thecartridge 70 in thehousing 14, theprotrusions 42 andrib members 58 contact thepaper products 12 within thecartridge 70 and act upon the paper products as described above. - The openings in the cartridge described above can be formed by removal of removable portions that may either be removed (or simply not formed) during manufacture of the cartridge or removed just prior to installation of the cartridge in the housing. If the removable portions are to be removed as part of the manufacturing process, the cartridge should be shipped to the user wrapped, for example in a polyethylene bag, to preserve the sterility of the paper products in the cartridge. If the removable portions are to be removed as part of the installation process, the edges of the removable portions should be weakened, scored, etc. for easy removal.
- The
cartridge 70 is desirably made of heavy paper or cardboard, but may be made of any other suitable material known to those skilled in the art such as, for example, durable plastic films and so forth. - Referring now to FIGS. 5 and 6, the
member 100 is shown having afirst portion 104 extending into theinterior area 32 of thehousing 14. Thefirst portion 104 of themember 100 engages and applies force to thepaper products 12. Thefirst portion 104 extends into the interior area 32 a sufficient distance to engage the paper products and may extend substantially to the opposing side wall of thehousing 14. Desirably, thefirst portion 104 extends from about ⅓ to about ½ of the way across the width of theinterior area 32 of thehousing 14. Thefirst portion 104 of themember 100 should be sufficiently sturdy to withstand substantial deflection from application of force against thepaper products 12. - The
member 100 further includes asecond portion 106 disposed substantially within theslot 60 in the sidewall of thehousing 14. Thesecond portion 106 of themember 100 is attached to amoveable slide 107 disposed within a track 108. The cross-sectional area of theslide 107 is slightly smaller than the cross-sectional area of the track 108 to allow for free movement of the slide within the track. Theslide 107 is also sufficiently long to substantially reduce and/or eliminate rocking within the track 108 that would inhibit free movement. - The track108 is defined within a
track housing 110. Desirably, thetrack housing 110 is external to the sidewalls of thehousing 14. Thetrack housing 110 is be attached to the sidewall over theslot 60 by any of a variety of ways known to those skilled in the art including, but not limited to, using adhesives, screws, nuts and bolts, and/or nails, and so forth. - Force is applied to the
slide 107 in the dispensingdirection 62 by aspring 102 disposed within the track 108. Theslide 107 and thespring 102 move within the track 108, but are constrained from falling out of the track because theslot 60 in the side wall of thehousing 14 is narrower than the slide and the spring. Because thespring 102 is compressed within the track 108, thespring 102 urges theslide 107 and the attachedmember 100 in the dispensingdirection 62. Thus, whenpaper products 12 are placed in thecontainer 10, thereby engaging themember 100, moving the member towards theend wall 20 of thecontainer 10, and compressing thespring 102, the extension force of the spring acting on the member urges thepaper products 12 toward the dispensingopening 40. Whencartridge 70 containingpaper products 12 is loaded incontainer 10, themember 100 extends through the cartridge slot 88 (shown in FIG. 4) to engage thepaper products 12. Use of the spring mechanism described above allows thecontainer 10 to be used in those situations where paper products are to be dispensed in a substantially horizontal or upward direction, i.e., where the paper products will not be urged towards the dispensing opening by the force of gravity. - The
spring 102 is sized to provide sufficient force to urge thepaper products 12 to the dispensingopening 40. Desirably, thespring 102 applies substantially constant pressure against thepaper products 12 at all positions of travel. Application of substantially constant pressure helps to prevent over-application of force when themember 100 is towards theend wall 20 of thehousing 14 and under-application of force when the member is closer to thedispenser opening 40. - It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope and spirit of the invention. It is intended that the present invention include such modifications and variations as come within the scope of the appended claims and their equivalents.
