Patent Application
20200375414
The present application relates generally to towel or wipe dispensers, and more particularly, to an assembly and method of providing a pull-through towel dispenser assembly wherein the towel dispenses from a core of a bulk or source roll of towel paper web material.
Towel and wet wipes are commonly understood as sheets of a web of paper type material. Such towels and wipes can be provided in a number of configurations and provided as a dry wipe material or moistened with a fluid associated with the intended use of the discrete towel or wipes. Largely due to the convenience associated with their use, towels and wipes can be provided in various configurations associated with the intended use of the discrete web materials. Some such uses include cleaning parts of the human body, hand towels or wipes, use as toilet paper or baby wipes, degreasers, electronics cleaners, dust wipes, automotive applications including tire, leather, window, glass, and/or vinyl or plastic treatment, cleaning, and/or conditioning materials, etc. It is appreciated that the list provided above is in no way exhaustive or all-inclusive of the uses of such towels or wipes. It is further appreciated that the material and/or construction of the web material, as well as the material associated with moistening the towels or wipes, can be provided in a plethora of combinations associated with the intended use of the discrete towels or wipes for cleaning, sanitation, and/or surface or material conditioning treatments. It is further appreciated that, depending on the intended use of the discrete towels or wipes, such web materials can be provided in either of a non-moistened or dry configuration.
Whether provided in a wet or dry modality, such towels or wipes are occasionally provided in a disposable bag or canister that includes a dispensing structure that allows sequential extraction of one or more wipes when desired. The dispensing structure commonly includes a lid or other closure assembly that movably cooperates with a cover or bezel associated with the container. When provided to dispense wet or pre-moistened towels or wipes, the lid commonly provides a sealed interaction with the remainder of the container or cover to mitigate drying out of the wipes prior to use. Some towel or wet wipe containers are provided as disposable bags of wipes whereas other wipe dispensing containers are formed as selectively operable boxes or canisters that are configured to be re-useable and/or refillable. Such distribution or use approaches tend to produce substantial waste when deployed in heavy or frequent use environments.
Many such dispensers also include a wipe or towel separation structure defined by the cover or lid of the contained and that is configured to interact with the web material to effectuate sequential dispensing and/or separation between adjacent discrete units of the web material until the contents of the container are consumed. That is, many dispensing structures are constructed to cooperate with the web material of the towel or wipes so that at least an end portion of a subsequent towel or wipe is restrained by the separation structure in a manner such that the end of the subsequent towel or wipe can be grasped by the user but does not otherwise interfere with the desired opening and closing of the lid and a preferred sealed interaction between the lid and the remainder of the cover or container after each use of a discrete towel or wipe. Such approaches tend to increase manufacturing costs associated with formation of such dispenser assemblies and can detract from a desired sanitary operation of the dispensing container as each user interacts with the operable lid structures.
Unfortunately, many known personal use towel and wipe containers or dispensers are of relatively simple construction and the lids occasionally fail to provide desired separation between adjacent towels or wipes during the sequential use of the same. If left unaddressed, failure to adequately attend to the desired separation between the towels and wipes can result in undesirable waste of the towels or wipes due to the undesirable dispensing operation of the dispenser.
Many such personal use towel and wipe containers or dispensers suffer from additional drawbacks associated with use of the same. For instance, many such dispensers or containers are constructed to be easily transported and/or require two-handed interaction with the dispensing container to effectuate each dispensing event. Commonly, the user must grip, restrain, or otherwise secure the container or dispenser with one hand while extracting a desired number of towels or wipes. Whether provided as a personal supply or a bulk or multiple user supply of towels or wipes, if the restriction or separation mechanism fails to adequately effectuate the desired separation between adjacent towels or wipes, the user must interact with each of the adjacent wipes to effectuate the desired separation therebetween. Such operations detract from sanitary operation of the dispenser and can expose subsequent users to any materials associated with the prior user's interaction with the exposed or graspable portion of a subsequent towel or wipe.
Still further, many such towel or wipe dispenser assemblies are commonly constructed to effectuate sequential removal of towels or wipes from an exterior surface of the bulk source of towel or wipe web material. Such methodologies commonly employ a sequential folded interaction between adjacent wipes or must be configured to accommodate rotational support of a roll of web material such that the roll of bulk web material is consumed in a sequential manner from an exterior surface of the roll—a manner customary to dispensing of toilet tissue. Each methodology presents unique considerations to the manufacturer and proper presentation of the towels or wipes during the dispense operation and providing the desired separation between the adjacent towels or wipes when desired. Unfortunately, such approaches also operate in a dispense methodology wherein the exterior of most towels or wipes associated with the bulk source roll, the towels and wipes most susceptible to the undesirable effects of evaporation, are dispensed in a sequential manner Such approaches can result in excessive waste of the web material in that users tend to discard towels or wipes perceived to be insufficiently moist relative to previously used towels or wipes. Further exacerbating this shortcoming, each use of a desired towel or wipe or number of towels or wipes, leaves the next to be dispensed towel or wipe exposed to the conditions that resulted in drying out and/or ultimate waste of a preceding towel or wipe or wipes.
Accordingly, there is a need for a towel or wipe dispenser system or assembly that can support a bulk roll of web material and that is constructed to facilitate single handed interaction therewith. There is a further need for a web material dispenser assembly that accommodates a center-pull dispense methodology from the bulk source of web material. There is a further need for a web material towel or wipe dispenser system having an adjustable dispense assembly such that the dispenser assembly can be deployed with towels or wipes having different separation methodologies and/or various different dispense performance characteristics when dispensed in a center-pull manner There is a further need for a center-pull dispenser assembly having an adjustable dispensing aperture that can be secured in a desired orientation to mitigate nefarious interaction with the dispenser assembly.
The present application discloses a center pull-through web material dispenser assembly and method that overcomes one or more of the shortcomings disclosed above. One aspect of the present application discloses a dispenser assembly that includes a housing having a base and a moveable cover. A roll support is disposed in the housing and defines a portion of a material dispense passage. A restrictor plate is supported by the roll support and is rotatable and axially translatable relative to the roll support. The restrictor plate defines a number of dispense openings that can each be selectively aligned with the portion of the dispense passage defined by the roll support. Each of the discrete dispense openings defined by the restrictor plate have a size and/or shape that is different than a size and/or shape of the other discrete dispense openings such that the characteristics associated with the pull-through dispense activity of the dispenser assembly can be quickly and conveniently configured to achieve a desired dispense action.
Another aspect of the present application that is useable or combinable with one or more of the above features or aspects discloses a pull-through web material dispenser assembly having a housing that defines a cavity shaped to receive a roll of web material. A platform is disposed in the housing and shaped to support an end of a roll of web material disposed in the housing. A passage is formed through the platform and has a frustoconical shape such that a cross-sectional area of the passage reduces as the passage progresses away from the cavity toward atmosphere. A dispense plate is attached to the platform such that the dispense plate is rotatable relative to the platform. A plurality of openings are formed through the dispense plate and each of the plurality of openings is oriented relative to the dispense plate and an axis of rotation of the dispense plate such that each of the plurality of openings can be independently selectively aligned with the passage formed through the platform. Such a construction allows the web material dispenser assembly to be quickly and conveniently configured to provide the desired separation between adjacent towels or wipes when dispensed in a pull-through manner.
Another aspect of the present application that includes various aspects or features that can be combined or are usable with various features or aspects of the apparatuses disclosed above includes a center pull-through towel dispenser assembly that includes a base and a cover that is connected to the base and movable between an open position and a closed position. A roll support extends in a generally horizontal direction between the base and the cover and a passage is formed through the roll support. The passage is defined by an inlet having an oblong cross-section shape and an outlet that is offset in a radial direction toward an edge of the roll support. A restrictor plate is rotationally connected to the roll support and a plurality of restrictor holes are formed through the restrictor plate. Each of the restrictor holes is offset in a radial direction from an axis of rotation of the restrictor plate relative to the roll support and oriented to be selectively axially aligned with the outlet of the passage formed through the roll support.
A further aspect of the present application that is usable or combinable with one or more of the aspects or features of the assemblies disclosed above includes a method of forming a pull-through dispenser assembly that includes providing a housing having a base and a cover that is moveably connected to the base so the housing is configured to provide an open configuration and a closed configuration. A support plate is provided that cooperates with the housing and is oriented to support a roll of web material in a vertical orientation. An opening is formed through the support plate and shaped to have an oblong inlet that extends in a radial direction across a portion of the support plate. A restrictor is provided that has a plurality of dispense openings and is configured to be supported by the support plate. The restrictor is supported relative to the support plate such that each of the plurality of dispense openings formed in the restrictor can be selectively axially aligned with an outlet of the opening formed through the support plate.
Yet another aspect of the present application that is combinable or usable with one or more the aspects or features of the methods and apparatuses disclosed above includes a method of adjusting a dispense passage defined by a center pull-through towel dispenser assembly. The method includes axially translating an orifice plate that has a plurality of discrete dispense orifices relative to a roll support plate that has a fixed shape dispense opening. Once translated, orifice plate can be rotated relative to the roll support plate until a desired one of the plurality of dispense orifices is axially aligned with the single dispense passage defined by the roll support plate. Releasing the orifice plate allows the orifice plate to translate in an opposite axial direction to a position wherein the orifice plate is non-rotatable relative to the roll support plate.
A dispenser assembly and method of providing a web material dispenser assembly that is configured to dispense web material in a pull-through manner from a core of a roll of web material. The dispenser assembly includes a housing having a base and a moveable cover. A roll support is disposed in the housing and defines a portion of a material dispense passage. A restrictor plate is supported by the roll support and is rotatable and axially translatable relative thereto. The restrictor plate defines a number of dispense openings that can be selectively aligned with the portion of the dispense passage defined by the roll support such that the characteristics associated with the pull-through dispense activity of the dispenser assembly can be quickly and conveniently configured to achieve a desired dispense action.

However, it is not intended that the invention be limited to the specific terms so selected and it is to be understood that each specific term includes all technical equivalents which operate in a similar manner to accomplish a similar purpose. The various features and advantageous details of the subject matter disclosed herein are explained more fully with reference to the non-limiting embodiments described in detail in the following description.
As disclosed further below, cavity 28 is shaped to accommodate and support a bulk roll 35 of web towel or wipe material 30 (
Base 24 includes a top wall 37, a lower wall 34, and opposing sidewalls 36, 38 that each extend from a rear wall 40. A forward facing edge 42 of base 24 has a shape that generally corresponds to a base facing edge 44 of cover 26. At least an upward oriented portion of forward facing edge 42 of base 24 optionally preferably sealingly cooperates with an upward oriented portion of base facing edge 44 of cover 26 when housing 22 is oriented in a closed orientation. A latch 46 is supported by base 24 and is shaped to selectively cooperate with a catch 48 defined by cover 26. One or more keys 50 are supported by rear wall 40 in a knock-out manner such that keys 50 can be selectively be removed from rear wall 40 when desired. Keys 50 are shaped to selectively cooperate with a keyhole 52 defined by cover 26 to manipulate the interaction between latch 46 and catch 48 to allow opening and closing of housing 22 and limit access to cavity 28 by only authorized personnel. One or more openings 54, 56, 58, 60, 62 are formed through rear wall 40 of base 24 and constructed to facilitate securing housing 22 relative to a support structure such as a wall or the like.
As disclosed further below, dispenser assembly 20 includes a guide, a roll support, a platform, a roll support plate, or a support assembly 66 that is preferably constructed to snap-fittingly cooperate with base 24 and oriented to support a bulk roll 35 of web material 30 placed thereupon when dispenser assembly 20 is deployed in a vertically upward directed orientation wherein the dispense opening is oriented to face in a generally downward vertical direction as reflected by the orientation shown in
Cover 26 includes a top wall 68 and a generally arcuate shaped sidewall 70 that is bounded by base facing edge 44 of cover 26. When deployed in an upright orientation, top wall 37 of base 24 and top wall 68 of cover 26 are oriented at a vertical uppermost position relative to the remainder of dispenser assembly 20. When deployed in an inverse or inverted orientation, top wall 37 of base 24 and top wall 68 of cover 26 are oriented at a vertical lowermost position relative to the remainder of dispenser assembly 20. It should be appreciated that a generally downward or radially outward directed extraction event is associated with upright positioning of dispenser assembly 20 and an upward or radially outward directed extraction event is associated with the inverted or upwardly directed orientation of the dispense passage when dispenser assembly is oriented such that top wall 37 of base 24 and top wall 68 of cover 26 are oriented in a generally downward facing direction relative to the remainder of the structure of housing 22. The remainder of the directional references, such as “upper”, “lower”, etc., provided hereafter will be provided relative to the upright orientation of dispenser assembly wherein top walls 37 and 68 are oriented in a vertically upward directed orientation as shown in
A lower portion 72 of cover 26 includes a recess 74 that is shape to cooperate with a forward facing edge 76 of support assembly 66 when cover 26 is oriented in a closed orientation 78 (
A lower portion 80 of dispenser assembly 20 includes a shroud 82 that extends generally circumferentially about a dispense area 84 of housing 22. Shroud 82 includes a first portion 86 that is defined by lower portion 72 of cover 26 and a second portion 88 that is generally defined by a lower portion 90 of base 24. Shroud 82 includes a lower edge 94 having one or more cutouts or a generally curvilinear shape that accommodates visual inspection of terminal end 32 of web material 30 during use of dispenser assembly 20 from one or more angles of approach to dispenser assembly 20 and whether dispenser assembly 20 is deployed in the upright or inverted vertical orientations.
Lower portion 72 of cover 26 includes a support, a partition, a stop, or a guard 96 that is configured to selectively interfere with operation or manipulation of an adjustable dispense assembly 100 supported by base 24. Guard 96 includes a channel 102 that is shaped to be generally aligned with the longitudinal axis associated with terminal end 32 of web material 30 during use of dispenser assembly 20. That is, channel 102 optionally defines a portion of the dispense passage associated with the sequential extraction of web material 30 in the pull-through manner during use of dispenser assembly 20. Alternatively, guard 96 could be provided with a generally arcuate terminal end that is shaped to obstruct axial translation of dispense assembly 100 with a deminimis contribution to the definition of the dispense passage.
Referring to
As disclosed further below, manipulation of restrictor plate 120 relative to support assembly 66 manipulates the configuration or shape associated with a portion of the dispense passage attributable to restriction plate 120 and associated with extracting the towel or wipe web material from dispenser assembly 20 during the pull-through activity. Referring to
Each of openings 130-142 are sized and shaped to facilitate passage of towel or wipe web material therethrough in a manner that effectuates passage of a next to be dispensed web material partially through the respective opening and in a manner that effectuates separation between adjacent discrete towels or wipes at a desired location associated with the extraction of the web material from the radial core 33 of the bulk roll 35 of web material 30. It should be appreciated that the web material is preferably intermittently partially perforated to effectuate the desired separation during extraction of the towels or wipes of web material during extraction from housing 22 while progressing the terminal end 32 of a subsequent towel or wipe, i.e. the end opposite the discrete perforation, to present through the respective opening 130-142 and to be positioned to be grasped for a subsequent dispense event.
It is further appreciated that the web materials, whether considered as towels or wipes, may be presented in dry or treated with cleaning or treatment fluids or solutions and/or prepared with different woven material thicknesses or weights depending on manufacturer preferences or the intended use of the discrete towels and/or wipes. Dispenser assembly 20 is constructed to accommodate dispensing of woven web materials having various dispense characteristics as a function of the construction and/or composition of the discrete towels or wipes and/or the formation of the discrete bulk roll 35. The constricting operation associated with the interaction of the web material 30 with the discrete opening 130-42, when properly selected, facilitates single-handed dispensing interaction with dispenser assembly and the ability of dispenser assembly 20 to be configured for single handled operation with web materials have varied constructions and in a manner that provides the desired separation between adjacent towels of the bulk roll without excessive roping of the towel web material during each discrete dispense event.
Restrictor plate 120 includes an interference engagement in the form of a toothed interface 150 that is defined by a plurality of discrete recesses 152 and projections 154 that extend about a circumference 156 of a post 158 that extends from a support plate facing surface 161 of restrictor plate 120. Toothed interface 150 of restrictor plate 120 is constructed to operatively cooperate with an interference engagement or toothed interface 160 associated with a post 162 extending from lower surface 112 of roll support assembly 66. Toothed interface 160 includes a number of projections 164 that are each separated from one another by respective recesses 166 and oriented to extend about a circumference 168 of post 162. Toothed interface 150 and toothed interface 160 mesh with one another so as to provide selective rotational cooperation between restrictor plate 120 and roll support 66 when desired. That is, when engaged with one another, toothed interfaces 150, 160 prevent rotation of restrictor plate 120 relative to roll support 66 and thereby prevent rotation of restrictor plate 120 relative to dispenser assembly 20 either by the user or inadvertently during the discrete dispense events.
Referring to
Referring to
Interfaces 150, 160 are each constructed such that the discrete projections or teeth 154, 164 and corresponding respective cavities or recesses 152, 166 mesh and thereby prevent rotation of restrictor plate 120 relative to support assembly 66 and such that the discrete axes associated with the cross-sectional continuous perimeters associated with each of the discrete openings 130-142 are preferably centrally disposed relative to the axis defined by outlet 118 associated with passage 114 of support assembly 66. Such a construction ensures the desired axial alignment of each discrete opening 130-142 with passage 114 defined by support plate 66 when desired to achieve the desired center pull-through web material dispensing performance.
Referring to
It should be further appreciated that opening of cover 26 of housing 22 translates stop 184 to a position that is offset from restrictor plate 120 such that, when housing 22 is open, a user can translate restrictor plate 120 in a generally downward or generally axially away from support assembly 66, and against the bias provided by spring 172, to effectuate disengagement of the interference engagements defined by toothed interfaces 150, 160 and subsequent rotation of restrictor plate 120 relative to roll support assembly 66 until a discrete or desired one of openings 130-142 is oriented in alignment with outlet 118 of support assembly 66.
Preferably, toothed interfaces 150, 160 are configured to engage or mesh with one another in a manner that inhibits rotation of restrictor plate 120 relative to support assembly 66 only when one of discrete openings 130-142 is axially aligned with the outlet 118 defined by passage 114. Such a consideration would mitigate the user's ability to unintentionally “misalign” relative to the axial alignment of a desired opening 130-142 relative to passage 114 but could also detract from the adjustability of restrictor plate 120 relative to support assembly 66 for those web materials wherein a degree of “misalignment” of the openings 130-142 relative to the axis of passage 114 may be desired to achieve a desired web material towel dispensing and separation performance.
In a preferred configuration, upon positioning of a desired one of openings 130-142 in the desired alignment with outlet 118, releasing restrictor plate 120 allows toothed interfaces 150, 160 to re-associate with one another and to define the general rotational orientation of restrictor plate 120 relative to support assembly 66 with the desired opening 130-142 restrained in the aligned orientation relative to outlet 118 of support assembly 66. Such a construction allows the user to quickly and conveniently manipulate the output dispense performance associated with passage 114, roll support assembly 66, and restrictor plate 122 and to manipulate the dispense performance associated with use of dispenser assembly 20. That is, openings 130-142 are shaped to facilitate the discrete incremental dispensing of web material from the core 33 of the bulk roll 35 source thereof and in a guided and constricting manner that allows and/or facilitates single-handed dispense activity with separation between adjacent towels or wipes associated with portions of the bull roll of web material and to achieve the desired separation between adjacent discrete towels or wipes at desired lines of perforation associated therewith during a dispense activity.
Preferably, when the user subjects terminal end 32 of web material 30 to a generally downward directed pulling load, discrete selected opening 130-142 associated with restrictor plate 120 provides a resistance to the downward directed pulling load and a resistance that is sufficient to effectuate the desired separation between adjacent towels, wipes, or portions of the bulk roll 35 of web material 30 during each extraction event and in a manner that presents a terminal end 32 of the next subsequent towel of web material at a grippable outboard location proximate restrictor plate 120. For instance, upon loading, if desired repeatable separation between adjacent towels does not occur, passing the terminal end 32 of the web material 30 through the next smallest bounded opening 130-142 defined by restrictor plate 120 will alter the separation performance between adjacent towels or wipes of the web material being dispensed.
Similarly, if too much force is required to effectuate each extraction event, passing the terminal end 32 of web material 30 through the next largest opening 130-142 will reduce the force associated with the pull-through extraction event and will also manipulate the discrete towel or wipe separation performance provided by dispenser assembly 20. Such considerations allow the user to individualize the use of dispenser assembly 20 to provide the desired dispense performance for web materials having various dispense performance characteristics due to the nature of the varied construction of the discrete bulk web material constructions associated with sourcing web material 30 and the core dispensing performance of such bulk materials.
As alluded to above, it is appreciated that dispenser assembly 20 can be deployed in an upright vertical orientation or an inverted vertical orientation and is configured to dispense, in a pull-through manner, towel or wipe web materials from a core of a bulk roll of web material. When deployed in the inverted vertical orientation, it is appreciated that housing 22 is shaped to accommodate a bulk roll of web material that could be supported by the surfaces of top wall 37 and top wall 68 of housing 22 that face cavity 28. Alternatively, it is appreciated that housing 22 could be constructed to cooperate with a supplemental support plate having a construction generally similar to support assembly 66 but without a passage formed therethrough.
It should be appreciated that such a support plate has a perimeter circumferential shape generally similar to assembly 66 and could preferable be constructed to snap-fittingly cooperate with base 24 in a manner similar to roll support assembly 66 but at a location proximate the cavity 28 facing sides of walls 37, 68. When deployed in an inverted orientation, such a supplemental plate would support the bulk roll of web material placed in cavity 28. Alternatively, base 24 and cover 26 are constructed such that a bulk roll of web material 30 can cooperate with the interior surfaces of walls 37, 68 when disposed in cavity 28 such that the center of gravity of the bulk roll 35 is located toward the base facing side of the plane defined by the interface of edges 42, 44 of base 24 and cover 26. Such a consideration allows self-supported position of a bulk roll of web material during loading operations and in a manner that allows two handed interaction by the user with the terminal end 32 of the roll of web material to effectuate adjustment of restrictor plate 120 when necessary and the threading of the terminal end 32 of the towel web material through passage 114 and subsequently through the selected or desired one of openings 130-142 during the initial web material loading operation.
Once loaded and the terminal end of the web material is threaded through the passage 114 of support plate assembly 66—which rests generally above the bulk roll of web material; and the desired opening 130-142 of restrictor plate 120, dispenser assembly operates and functions in the same manner as disclosed above. One distinct advantage to the inverted orientation of the dispenser assembly is that the bulk roll of web material 35 can be associated with cavity 28 and provided in a moistened configuration or contained in a plastic bag or the like such that the bulk web material can be maintained in a moistened or wet condition throughout the incremental consumption or usage of the entire or proximate the entire bulk roll of web material during a normal period of use.
The inverted orientation of the dispenser assembly and the containment of a volume of fluid therein allows use of dispenser assembly 20 to dispense pre-moistened web material towels or wipes from a core of a bulk roll of such material and in an orientation wherein any excess moisture associated with the discrete towels or wipes is communicated to the bulk source of web material during each extraction event and via the rope of web material progressing from the core of the bulk roll. Such considerations enhance the applicability and fields of use associated with dispenser assembly 20 and mitigate the costs associated with the manufacture of more personal use volumes of pre-moistened towels and wipes. Further, upon consumption or usage of a bulk roll of web material, any residual moistening agent can be conveniently communicated to the next bulk roll of web material associated with the dispenser assuming similar moisture agents exist between a consumed roll and a subsequent roll of bulk web material. Such concerns further mitigate production of waste associated with incremental dispensing of towel and wipe web materials from bulk sources.
Therefore, one embodiment of the application includes a pull-through web material dispenser assembly having a housing that defines a cavity that is shaped to receive a roll of web material. A platform is disposed in the housing and is shaped to support an end of the roll of web material received in the housing. A passage is formed through the platform and has a frustoconical shape such that a cross-sectional area of the passage reduces as the passage progresses away from the cavity toward atmosphere. A dispense plate is attached to the platform such that the dispense plate is rotatable relative to the platform. A plurality of openings are formed through the dispense plate, each of the plurality of openings is oriented relative to the dispense plate and an axis of rotation of the dispense plate such that each of the plurality of openings can be aligned with the passage formed through the platform. Such a construction defines a dispenser assembly that can be used to sequentially dispense web materials from bulk roll sources and in a manner that provides an adjustable pressure associated with the pull-through activity to provide a desired separation between the discrete towels or wipes associated with the bulk source.
Another embodiment of the present application that includes various features and aspects combinable with one or more of the embodiments, features, or aspects disclosed above includes a center pull-through towel dispenser assembly that include a cover that is connected to a base and that is movable between an open position and a closed position. A roll support extends in a generally horizontal direction between the base and the cover and a passage is formed through the roll support. The passage is defined by an inlet that has an oblong cross-sectional shape and an outlet that is offset in a radial direction toward an edge of the roll support. A restrictor plate is rotationally connected to the roll support and includes a plurality of restrictor holes that are formed through the restrictor plate. Each of the restrictor holes is offset in a radial direction from an axis of rotation of the restrictor plate relative to the roll support and is oriented to be selectively axially aligned with the outlet of the passage formed through the roll support such that each of the restrictor holes can be selectively deployed as a portion of the dispense passage defined by the housing.
A further embodiment of the present application that is useable or combinable with one or more of the above aspects or features discloses a method of forming a pull-through dispenser assembly. A housing is provided that has a base and a cover that is moveably connected to the base so the housing provides an open configuration and a closed configuration. A support plate is provided that cooperates with the housing and is oriented to support a roll of web material in a vertical orientation when the dispenser assembly is deployed in an upright vertical orientation. An opening is formed through the support plate and is shaped to have an oblong inlet that extends in a radial direction across a portion of the support plate. A restrictor is provided that has a plurality of dispense openings and that is supported by the support plate such that each of the plurality of dispense openings can be selectively axially aligned with an outlet of the opening formed through the support plate.
Yet a further embodiment combinable or usable with one or more of the aspects, features, or embodiments disclosed above includes a dispenser assembly and method of providing a web material dispenser assembly that is configured to dispense web material in a pull-through manner from a core of a bulk roll of web material. The dispenser assembly includes a housing having a base and a moveable cover. A roll support is disposed in the housing and defines a portion of a material dispense passage. A restrictor plate is supported by the roll support and is rotatable and axially translatable relative thereto. The restrictor plate defines a number of dispense openings that can be selectively aligned with the portion of the dispense passage defined by the roll support such that the characteristics associated with the pull-through dispense activity of the dispenser assembly can be quickly and conveniently configured to achieve a desired dispense action.
It is also to be understood that, although the foregoing description and drawings describe and illustrate in detail the preferred aspects of the present invention, to those skilled in the art to which the present invention relates, the present disclosure will suggest many modifications and constructions as well as widely differing embodiments and applications without departing from the sprit and scope of the invention. The present invention, therefore, is intended to be limited only by the scope of the appended claims and the applicable prior art.
Further, the invention may be implemented in a variety of configurations, using certain features or aspects described herein and others known in the art. Thus, although the invention has been herein shown and described in what is perceived to be the most practical and preferred embodiment, it is to be understood that the invention is not intended to be limited to the specific features set forth above. Rather, it is recognized that modifications may be made by one of skill in the art of the invention without departing from the spirit or intent of the invention and, therefore, the invention is to be taken as including all reasonable equivalents to the subject matter of the claims.
