Description




BACKGROUND OF THE INVENTION




This invention relates generally to the field of dispensing devices and systems. More particularly, this invention relates to the field of devices and systems for dispensing paper products such as napkins, towels, toilet tissue, etc.




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.




Unfortunately, large dispensers are subject to a number of drawbacks. First, it is difficult to uniformly dispense individual paper products from a large dispenser without dispensing more paper products than necessary to a user. Thus, too many paper products are removed by a user, and some of the paper products are wasted. If too many paper products are removed from a dispenser, the benefits provided by a larger dispenser are eliminated as the dispenser is emptied more rapidly.




Second, many dispensers are difficult to load, and that difficulty can increase with the size of the dispenser. 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. Also, 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 again defeating the benefits of the larger dispenser.




A further drawback of many currently available dispensers regardless of size is that it is impossible to determine without opening the dispenser how many paper products remain within the dispenser. Thus, a person must either periodically check the dispenser to determine how many paper products remain or be vigilant to refill the dispenser as soon as it is empty. Both alternatives involve much personal attention and, especially during peak usage, can lead to empty dispensers if dispensers are not vigilantly monitored.




OBJECTS AND SUMMARY OF THE INVENTION




It is a principle object of the present invention to provide an improved container and cartridge for dispensing paper products that can be readily adapted to various applications.




Another object of the present invention is to provide a container and cartridge for dispensing paper products that are simple and inexpensive to manufacture, and that are reliable in use.




Still another object of the present invention is to provide a container and cartridge for dispensing paper products that provide metered delivery of individual paper products.




Yet another object of the present invention is to provide a container and cartridge for dispensing paper products that reduce the incidence of waste of the paper products, either due to dispensing too many paper products to a user or due to dropping of the paper products during refilling of the container.




Still another object of the present invention is to provide a container and cartridge for dispensing paper products that provide an indication of the remaining amount of the paper products ready for dispensing to users.




Yet another object of the present invention is to provide a container and cartridge for dispensing paper products that reduce the incidence of jamming of paper products and the resultant inability to dispense further paper products.




Still another-object of the present invention is to provide a container and cartridge for dispensing paper products that supports the weight of paper products so that individual paper products are readily removed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




Reference will now be made in detail to the presently preferred embodiments of the invention, one or more examples of which are illustrated in the drawings. 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.




As broadly embodied in

FIGS. 1-5

, a first embodiment of container


10


is disclosed for dispensing paper products


12


. Container


10


includes a housing


14


in which paper products


12


are placed and from which paper products


12


are dispensed. Paper products


12


may be paper napkins, paper towels, toilet tissue, or any other similar material.




Housing


14


includes a number of exterior walls


16


for housing paper products


12


. The housing


14


includes a first end wall


40


and a second end wall


42


opposite the first end wall


40


. The first end wall


40


includes a dispensing throat


32


through which paper products


12


are individually removed by a user, as will be described below. A first wall


18


, a second wall


20


and a third wall


22


intersect the first end wall


40


, the second wall


20


and third wall


22


being on opposite sides of the first wall


18


. A fourth wall


24


extends between second wall


20


and third wall


22


. The exterior walls


16


(i.e., first wall


18


, second wall


20


, third wall


22


and fourth wall


24


) together define an interior surface


30


of housing


14


, within which an interior area


28


is located. As shown in

FIGS. 1 and 2

, exterior walls


16


and end walls


40


and


42


may each, if desired, be made of two planar portions. Such construction strengthens housing


14


and is useful in locations where the housing might be vandalized. The outer portions of walls


16


help withstand any blow or impact to housing


14


to prevent its destruction or removal of the housing from its mounting or paper products from the housing.




As shown in

FIG. 1

, fourth wall


24


includes a door


34


which may be hingedly attached to third wall


22


(or to the second wall


20


). Door


34


is openable for insertion of paper products


12


into interior area


28


of housing


14


when the supply of paper products


12


runs low. Door


34


includes a latching mechanism


36


including a number of interfering notched tabs


38


on door


34


and second wall


20


that hold door


34


closed. Tabs


38


on either door


34


or second wall


20


are movable when desired to reopen door


34


by turning a key lock (not shown). The lock may be either located on door


34


, in which case the tabs


38


on door


34


are movable, or on the main part of housing


14


, in which case the tabs


38


on second wall


20


are movable. Leaf springs


39


may be provided to assist in reopening door


34


upon unlocking. Any other type of latching mechanism for reopenably securing door


34


may be used within the scope of the invention.




It is contemplated that the fourth wall


24


may be fixed and the paper products


12


may be inserted into the interior area


28


of the housing


14


through the second end wall


42


. In such case, the second end wall


42


may be fitted with latches, springs and the like. It is also contemplated that the second end wall may be removed entirely and that portion of the housing be left open.




In accordance with the invention, a means is provided for urging paper products


12


within interior area


28


toward dispensing throat


32


in a dispensing direction


44


. Various alternatives are possible within the scope of the invention to urge paper products


12


toward dispensing throat


32


in dispensing direction


44


.




For example, as shown in

FIGS. 1 and 2

, an attachment portion


46


of housing


14


may be provided for attaching housing


14


to a substantially nonhorizontal surface such as vertical wall


48


. As shown in

FIG. 2

, attachment portion


46


may define holes through first wall


18


of housing


14


for receiving attachment members (not shown) such as screws, bolts, nails, etc. for attaching housing


14


to wall


48


. Alternately, a mounting bracket could be formed on an exterior surface of first wall


18


for contacting and being supported by another bracket, screws, bolts, nails, etc. extending from wall


48


. Further, housing


14


could be secured to wall


48


via a glue, epoxy, etc., or any other type of adhesive. Also, it would be possible to locate attachment portion


46


on any part of housing


14


, such as second wall


20


, third wall


22


, first end


40


, or second end


42


, and to use combinations of mounting devices on several of the above-identified parts of housing


14


. Further, housing


14


could simply be positioned such that first end


40


is lower than second end


42


, and so that first end


40


and possibly first wall


18


are supported in some way without fixing housing


14


to any particular structure.




Thus, the means for urging paper products


14


toward dispensing throat


32


in dispensing direction


44


may comprise any structure or orientation, or both, of housing


14


and/or wall


48


that allows paper products


12


to be dispensed from dispensing throat


32


and to be urged in dispensing direction


44


by gravity. A second type of a mechanism for urging paper products


12


toward dispensing throat


32


in dispensing direction


44


will be discussed below in relation to a second embodiment (


110


) of container


10


.




In accordance with the invention, at least one protrusion, referred to generally as


50


, extends from interior surface


30


on at least one of exterior walls


16


into interior area


28


of housing


14


. Preferably, as shown in

FIG. 2

, second wall


20


and third wall


22


include protrusions


50


extending into interior area


28


. Protrusions


50


preferably comprise curved bumpers


52


, which may include a plurality of ridges


54


extending across the curved bumpers perpendicular to dispensing direction


44


.




As shown best in

FIG. 2

, bumpers


52


extend into interior area


28


to contact paper products


12


and thereby oppose the means for urging paper products


12


in dispensing direction


44


. By extending into interior area


28


to contact paper products


12


, bumpers


52


impede the movement of paper products


12


toward dispensing throat


32


, but do not prohibit such movement. Ridges


54


allow numerous paper products


12


to be contacted by an individual bumper and allow for a smoother movement of paper products through housing


14


. In embodiments where the means for urging paper products


12


in dispensing direction


44


includes mounting housing


14


so that gravity causes such movement, protrusions


50


also support paper products


12


against the force of gravity. Protrusions


50


therefore reduce the gravitational force of the bottom of the paper products


12


on dispensing throat


32


, thereby making it easier for a user to remove individual paper products from dispensing throat


32


.





FIG. 3

shows a preferred profile of one of the bumpers


52


. As shown, the exterior curve of bumper is defined by a radius r of from about 1.125 to 1.750 in. The bumper has a chordal length


1


of from about 1.625 to 1.875 in. Two ridges


54


each have a radius of from about 0.125 to 0.250 in., and their centers are each spaced about 0.250 in. from the center of bumper


52


. While the disclosed bumper shape is the currently preferred shape, other shapes could be used if desired.




In accordance with the invention, protrusions


50


on second wall


20


are desirably staggered from protrusions


50


on third wall


22


relative to dispensing direction


44


. Such staggering provides a smooth movement of paper products


12


along dispensing direction


44


and out dispensing throat


32


. Paper products


12


, being supported alternately on one side or the other by the staggered protrusions


50


, “walk” down housing


14


in dispensing direction


44


and out dispensing throat


32


. Staggering protrusions


50


in dispensing direction


44


is important in embodiments where paper products


12


are moved in dispensing direction


44


due to the mounting or orientation of housing


14


by gravity. For example, if protrusions


50


were spaced opposite from each other on second wall


20


and third wall


22


, paper products


12


might be entirely prevented from moving in dispensing direction and thus sit on top of a pair of protrusions


50


. Also, paper products


12


might unevenly move in spurts past a pair of non-staggered protrusions


50


which could lead to misaligning of paper products and ultimately jamming of paper products within housing


14


. Thus, staggering of protrusions


50


allows an orderly walking of paper products


12


along housing


14


in dispensing direction


44


where first one side of the paper products, and then the other, moves more steadily toward dispensing throat


32


.




Preferably, container


10


includes a second group of protrusions


50


extending from first wall


18


and fourth wall


24


into interior area


28


to contact paper products


12


. The second group of protrusions


50


is preferably disposed in a staging area


56


near dispensing throat


32


for spacing, slowing, aligning and supporting paper products


12


as they are moved in dispensing direction


44


through dispensing throat


32


. Preferably, the second group of protrusions


50


includes several rib members


58


extending parallel to dispensing direction


44


on both sides of the dispensing throat


32


as shown in FIG.


4


A. Rib members


58


may have different dimensions to properly support and guide the paper products


12


into the dispensing throat


32


as illustrated in FIG.


4


B. In particular, a tall rib member


59


which is adjacent first wall


18


and first end wall


40


extends into the interior area


28


by a greater amount than short rib member


60


. Tall rib member


59


is illustrated to show an exemplary sloping configuration and an optional radius of curvature. As can be seen in

FIG. 4A

, a top surface


62


of the tall rib member


59


closest to the dispensing throat


32


may be offset from the first end wall


40


. The short rib member


60


is adjacent the fourth wall


24


and the first end wall


40


. The short rib member


60


is illustrated to show an exemplary sloping configuration. As illustrated in

FIG. 4A

, a top surface


64


of the short rib member


60


may be configured so there is no offset from the first end wall


40


.




Generally speaking, the tall rib member


59


may have a height ranging from about 1 to about 2 inches at the location where it intersects with the first wall


18


and an offset or height ranging from about 0.1 to about 0.5 inch adjacent the dispensing throat. As an example, the tall rib member


59


may have a height of about 1.5 inch at the location where it intersects with the first wall


18


and an offset or height of about 0.25 inch adjacent the dispensing throat.




The short rib member


60


may have a height ranging from about 0.5 to about 1.5 inch at the location where it intersects with the fourth wall


24


and an offset or height ranging from 0 to about 0.24 inch adjacent the dispensing throat. As an example, the short rib member


60


may have a height of about 0.75 inch at the location where it intersects with the fourth wall


28


and no offset or height adjacent the dispensing throat.




However, it should be understood that the dimensions of these rib members may be varied to accommodate a variety of factors including, but not limited to, the size of the paper product, basis weight of the paper product, composition/texture of the paper product, fold pattern of the paper product, height of the stack of paper products, force supplied by the means to urge the paper products to the dispensing throat, amount and dimensions of protrusions located on the second and third walls of the container as well as amount of other rib members positioned proximate the dispensing throat.

59


.

FIG. 4C

is a sectional view taken along line

in

FIG. 4A

showing a portion of an exemplary short rib member


60


. 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.

Housing


14


may be made of injection-molded plastic such as polyethylene or nylon. However, other suitable materials, such as other plastics or metals, may be provided for any or all of the parts of housing


14


. Curved bumpers


52


and rib members


58


are preferably formed integral with housing


14


. However, curved bumpers


52


and rib members


58


may be formed separately from housing


14


and attached later. Also, curved bumpers


52


and rib member


58


may be made of different material from housing


14


if desired. For example, curved bumpers


52


and/or rib members may be made of a more resilient material than the materials described above, such as an elastomer or rubber.




While curved bumpers


52


have been described as disposed on second and third walls


20


and


22


, which are side walls in

FIGS. 1 and 2

where housing


14


is mounted to wall


48


, curved bumpers


52


could be disposed on any pair of opposite walls of housing


14


. Also, although rib member or members


58


have been described as disposed on first and fourth wall


18


and


24


, which are front and back walls in

FIGS. 1 and 2

, rib member or members


58


could be disposed on any wall or pair of opposite walls of housing. Preferably, curved bumpers


52


are disposed on one such pair of walls and rib member or members


58


are disposed on one or both of a different pair of side walls located


90


from those on which curved bumpers


52


are located.




Dispensing throat


32


may have many shapes within the scope of the present invention, as long as the throat provides easy access for a user and metered delivery of individual paper products.




Preferably, paper products


12


are interfolded or tab interfolded to provide metered feeding of individual napkins one at a time. However, the present invention does not require the use of interfolded paper products.




Housing


14


may hold multiple clips of paper products


14


, as shown in

FIG. 5.

, and may extend from


30


to as much as


48


in. from end to end. Preferably, first wall


18


is angled between 0-5 from the vertical to prevent paper products from falling out of housing


14


during refilling.




A second embodiment of the present invention is shown in

FIG. 6

, which discloses a container


110


similar to container


10


in most ways. Container


110


includes a housing


114


holding paper products


112


and including exterior walls


116


. The paper products


112


are dispensed in a dispensing direction


144


through a dispensing throat


132


. At least one protrusion


150


extends from interior surface


130


into interior area


128


to contact paper products


112


.




Protrusions


150


include curved bumpers


152


including ridges


154


similar to those discussed above in connection with the first embodiment of the invention. Curved bumpers


152


are staggered in dispensing direction


144


as discussed above. A staging area


156


is provided adjacent dispensing throat


132


at first end


140


of housing


114


. Staging area


156


includes additional curved bumpers


153


not staggered in dispensing direction


144


. Bumpers


153


allow paper products


112


to bow at the middle toward dispensing throat


132


to make it easier for a user to remove a single paper product from dispensing throat


132


.




In container


110


, the means for urging paper products


112


from interior area


128


toward dispensing throat


132


in dispensing direction


144


is different from that of container


10


. As shown in

FIG. 6

, a spring-loaded plate


155


is disposed within second end


142


of housing


114


along with at least one spring


157


. When spring


157


is compressed by spring-loaded plate


155


, spring


157


urges spring-loaded plate


155


in dispensing direction


144


. Thus, when paper products


112


are placed in container


110


and spring-loaded plate is pushed to the right (as shown in

FIG. 6

) thereby compressing spring


157


, spring-loaded plate


155


and spring


157


urge paper products


112


in dispensing direction


144


toward dispensing throat


132


. Use of a spring-loaded plate and spring mechanism allows container


110


to be used in situations where dispensing direction


144


is substantially horizontal. Thus, container


110


, which provides spring-loaded urging, can be used in locations where container


10


, which provides gravity-assisted urging, could not. It should be understood that the staging bumpers


153


of container


110


could be replaced with rib members similar to those used with container


10


shown in FIG.


1


and as depicted, for example in FIG.


4


A through FIG.


4


D.




In accordance with the third embodiment of the present invention, a container


210


is provided for holding paper products


212


to be dispensed to a user. As shown in

FIGS. 7-9

, container


210


includes a housing


214


defined by exterior walls


216


, including first wall


218


, second wall


220


, third wall


222


, and fourth wall


224


. Exterior walls


216


define an interior surface


230


, within which is disposed an interior area


228


. A dispensing throat


232


is provided through first end wall


240


which is positioned opposite a second end wall


242


. Paper products


212


are dispensed in a dispensing direction


244


through dispensing throat


232


. Housing


214


includes plurality of protrusions


250


, including curved bumpers


252


having ridges


254


and rib members


258


disposed in a staging area


256


.




However, housing


214


need not include a door, as found in some other embodiments of the invention, although a door may be provided for security reasons. In this embodiment, the fourth wall


224


is quite small and located near the dispensing opening


232


in the first end wall


240


leaving a face of the container


210


substantially open Further, housing


214


can also be constructed with double walls, as in housing


14


, for security reasons. Also, paper products


212


are not directly loaded into interior area


228


, as in the first and second embodiments.




As shown in

FIG. 8A

, a cartridge


262


is provided for insertion into interior area


228


of housing


214


for containing paper products


212


to be dispensed. As shown in

FIG. 7

, cartridge


262


is sized to fit snugly within interior area


228


of housing


214


. If desired, leaf springs


264


may be provided attached to the inside of second end


242


of housing


214


to hold cartridge


262


in place. Any other suitable mechanism such as a tab or other interlock may be used to hold cartridge


262


in housing


214


within the scope of the invention.




Preferably, cartridge


262


includes a plurality of removable portions


268


, the removal of which creates openings


270


through cartridge


262


. As shown in

FIG. 8A

, cartridge


262


includes a plurality of removable portions


268


that create openings


270


upon removal. Removable portions


268


are disposed in outside walls


272


of cartridge


262


so that, once removable portions


268


are removed, openings


270


encompass and receive protrusions


250


extending from interior surface


230


of housing


214


. Thus, upon removal of removable portions


268


and placement of cartridge


262


in housing


214


, curved bumpers


252


and rib members


258


contact the paper products


212


within cartridge and act just as the bumpers and rib members do in the first two embodiments of the invention.




Cartridge


262


may also include another removable portion


278


disposed at end


280


of cartridge


262


. Removable portion


278

FIG. 6

with a spring-loaded plate.




As shown in

FIG. 8A

, a removable portion


274


may be provided at end


276


of cartridge


262


so that paper products


212


can be supported and aligned by rib member


258


for dispensing through dispensing throat


232


. Alternately, end


276


of cartridge


262


may be formed as shown in

FIG. 8B

, so that removable portion


274


is not required and cartridge


262


fits into housing


214


without substantial modification of end


276


. Thus, if desired, a plurality of smaller removable portions


274




a


(see

FIG. 8B

) may be provided corresponding to rib members


258


and a smaller removable portion


274




b


may be provided corresponding to dispensing throat


232


. Of course, these removable portions


274




a


and


274




b


may simply not be formed or may be removed during manufacture of the cartridge.




Removable portions


268


,


278


, and


274




a


may either be removed (or simply not formed) during manufacture of cartridge


262


or removed during installation of cartridge


262


in housing


214


. If removable portions


268


,


278


, and


274




a


are to be removed as part of the manufacturing process, cartridge


262


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 removable portions


268


,


278


, and


274




a


are to be removed as part of the installation process, the edges of the removable portions should be weakened, scored, etc. for easy removal. Removable portion


274


should not be removed as part of the manufacturing process to ensure that paper products


12


remain properly loaded in cartridge


262


.




As shown in

FIG. 8A

, optional removable portions


268




a


may be placed on front wall


272


(and/or a back wall which is not shown) of cartridge


262


. Removable portions


268




a


may be used if optional protrusions


258


(i.e., rib members of the type shown in

FIGS. 4A-4D

) are used on the first wall


218


and the fourth wall


224


of housing


214


(see, for example, FIG.


7


). Such protrusions or rib members


258


may also be used on the first wall


18


and the fourth wall


24


of first embodiment housing


14


, if desired.




Preferably, cartridge


262


includes at least one slot


282


extending through one of the cartridge walls


272


. Slot


282


is visible from outside of housing


214


when cartridge


262


is mounted in interior area


228


. A user can visually determine the amount of paper products


212


remaining within cartridge


262


by inspecting the amount of paper products visible through slot


282


. As shown in

FIG. 8A

, two slots may be provided to provide a greater range of visual inspection. Any number or arrangement of slots is possible within the scope of the invention.




Cartridge


262


is preferably made of heavy paper or cardboard, but may be made of any other suitable material within the scope of the invention.
