Definitions
- the present invention is generally directed to a dispenser product lockout system and, more particularly, to a rolled web material dispenser having a mechanical lockout feature that prevents use of a dispenser assembly for dispensing rolled web material that is acquired from non-approved or unauthorized sources.
- conventional paper and web material roll dispensers are not commonly configured to selectively dispense only a particular type, style, or roll of web material or a roll of web material from a particular manufacturer. Accordingly, it is possible for a size discrepancy or mismatch to occur between the dispenser and the roll of web material, thereby inhibiting the proper dispensing of the web material.
- Such systems also present the potential that service providers or employees may configure such dispensers to dispense product having less desirable construction or performance characteristics via cheaper source suppliers or the like. Shortcomings in the dispense operation can sometimes be incorrectly attributed to subpar operability of the dispenser assembly rather than being attributable to deviations in the manufacture of the discrete rolled web material and/or use of rolled web materials that are ill-suited for being dispensed from a given dispenser assembly or produced with subpar manufacturing practices.
- US6027069 A describes a plastic membrane dispenser is composed of a holding member and a pivoting member fastened pivotally with the holding member.
- the holding member has a cylindrical shaft which is provided at one end thereof with a protruded lip and a recess extending toward another end of the cylindrical shaft.
- the recess is provided with a retaining surface.
- the pivoting member has a cylindrical body and an arresting surface.
- the cylindrical body is provided with a receiving hole dimensioned to receive therein the cylindrical shaft of the holding member.
- US2015150422 A1 describes a paper roll end support plug includes a first plug member non-rotatably mounted on a dispenser and a second plug member inserted in the paper roll end and rotatable relative to the first plug member, the plug members being in frictional engagement to prevent overspin of the paper roll during dispensing of paper from the roll.

- insert 504 and hub 502 are engaged with one another such that projections 560 associated with fingers 550 are engaged with channel 530 defined by hub 502, rotational interaction of insert 504 and the roll of web material associated therewith relative to hub 502 is provided in a manner that allows the roll of web material to be rotated but with limited free rotation therebetween after each dispense event.
- Such considerations mitigate instances of dispensing more web material than is desired and/or free spinning of the roll of web material 172 between dispense events.
- hub 502 and insert 504 cooperate with one another so as to define a first bearing surface 580 and a second bearing surface 582 that are formed between the respective adjacent radially facing surfaces of hub 502 and insert 504.
- Bearing surface 580 of roll lockout system 500 is radially nearer axial centerline 526 than bearing surface 582.
- bearing surfaces 580, 582 are also offset relative to one another along axis 526.
- Such a construction provides stable rotational support between insert 504, and a roll of web material associated therewith, and the hub 502 associated with the respective underlying dispenser assembly and/or respective support arm 22, 122 associated therewith and as disclosed further above.
- Bearing surfaces 580, 582 further each provide a generally circumferential rotationally supported interaction between hub 502 and insert 504 when associated with one another and do so in a manner that offsets the rotational support between hub 502 and insert 504 from the axial indexing cooperation associated with the cooperation of projections 560 with channel 530.
- Such considerations provide robust rotational support between hub 502 and insert 504 to better accommodate the mass of a full roll of web material when associated therewith.
- the construction and orientation of the plurality of retainers or fingers 550 associated with roll lockout system 500 can similarly be provided in numerous configurations.
- user manipulation of insert 504 allows fingers 550 to deflect in respective outward radial directions, indicated by arrows 576, to facilitate the removal or disengagement of a discrete insert 504 from the relative underlying hub 502 to accommodate replacement, replenishment, or re-loading of dispenser assembly equipped with hub 502 with a roll of web material having an insert 504 associated with its bore and thereby correlating to an authorized respective roll of web material.
- roll lockout system 500 can be configured with other radially spaced and/or numbers of deflectable retainers or fingers and/or numbers and constructions other than that which is shown in the drawings.
- fingers 550 may be provided in more of fewer fingers 550 than shown in the figures, other radial shapes or sizes, and/or to have projections 560 associated therewith and/or configured to cooperate with a respective portion of insert 504 so as to facilitate the rotational cooperation therebetween, the axially indexed relative position therebetween, and do so in a manner that mitigates axial dissociation or translation of insert 504, and the roll of web material associated therewith, relative to hub 502, during use of the underlying dispenser assembly.
- insert 504 is preferably constructed to interchangeably cooperate with hubs or hub assemblies having constructions that differ from hub 502.
- body 538 of insert 504 of roll lockout system 500 includes an overlapping portion 592 such that body 538 of insert 504 has a generally S or Z shaped cross-sectional shape as the shape or cross-section of insert 504 progresses between end 544 associated with fingers 550 and hub facing end 540 of body 538.
- overlapping portion 592 of insert 504 is may be disposed in alignment with bearing surface 582 or disposed between bearing surfaces 580, 582.
- overlapping portion 592 of insert 504 is disposed between bearing surfaces 580, 582 in both the axial direction associated with axis 526 and the radial direction as indicated by arrows 576. As shown, the separation between adjacent fingers 550 extends between an open end proximate projections 560 and a closed end proximate overlapping portion 592 such that each finger 550 extends in a cantilevered manner relative to the remainder of body 538 from a position proximate overlapping portion 592.
- overlapping portion 592 is formed toward the hub directed side of insert 504 relative to axis 526 and relative to end 544 thereof. That is to say, although insert 504 could be constructed such that overlapping portion 592 be oriented axially outboard of each of bearing surfaces 580, 582, overlapping portion 592 is preferably shaped and positioned to be axially aligned or overlapping in radial directions one of bearing surfaces 580, 582 or located axially therebetween.
- overlapping portion 592 is constructed to maintain the deflectable nature associated with operation of fingers 550 relative to hub 502, facilitate initial alignment of an insert 504 equipped roll of web material with hub 502, attain the desired engagement of a roll of web material with the dispenser, removal of any residual portion associated with a previously consumed roll of web material, and do not otherwise interfere with or detract from the dual bearing surface 580, 582 rotational support associated with the rotational dispensing engagement provided by the selectively severable association of discrete inserts 504 and hub 502.
- Figs. 6-9 disclose a roll lockout system 600 according to yet another embodiment of the application.

Description
- The present invention is generally directed to a dispenser product lockout system and, more particularly, to a rolled web material dispenser having a mechanical lockout feature that prevents use of a dispenser assembly for dispensing rolled web material that is acquired from non-approved or unauthorized sources.
- Conventional rolled web material dispensers for use in dispensing hand towel and toilet tissue material or the like often advance the web material from a roll as the roll rotates about a spindle, bobbin, or hub located within the dispenser. Upon depletion of the rolled web material, the dispenser housing is opened, and a replacement roll of web material is then placed within the dispenser. Conventional rolls of web materials may be coreless or include a hollow core for receiving a generic or common spindle that extends laterally through the core and whose opposing ends are supported by the dispenser housing. When provided in a coreless configuration, the axially opposing end located portions of the web material may be pinched between opposing fingers or compression assemblies that collectively define the rotational axis of the roll of web material relative to the dispenser.
- Whether provided in a cored or coreless configuration of rolled web material, conventional paper and web material roll dispensers are not commonly configured to selectively dispense only a particular type, style, or roll of web material or a roll of web material from a particular manufacturer. Accordingly, it is possible for a size discrepancy or mismatch to occur between the dispenser and the roll of web material, thereby inhibiting the proper dispensing of the web material.
- Such systems also present the potential that service providers or employees may configure such dispensers to dispense product having less desirable construction or performance characteristics via cheaper source suppliers or the like. Shortcomings in the dispense operation can sometimes be incorrectly attributed to subpar operability of the dispenser assembly rather than being attributable to deviations in the manufacture of the discrete rolled web material and/or use of rolled web materials that are ill-suited for being dispensed from a given dispenser assembly or produced with subpar manufacturing practices. Improper or less than efficient operation of the rolled web material dispenser to dispense rolled web material in a repeatable manner, but attributable to improper loading or use of a dispenser with web material not properly configured for cooperation with a discrete dispenser assembly, may reflect adversely on the manufacturer of the dispenser rather the establishment or service provider associated with maintaining operation of the discrete dispenser assemblies once deployed and ensuring that only suitable rolled web materials are associated therewith. Accordingly, there is a need for a roll dispenser that is constructed to limit use of the dispenser assembly to dispense only desired rolled web materials and thereby inhibit use of the dispenser assembly to dispense rolls of web material that have not be authorized to be dispensed from the corresponding dispenser.
- Further, a need exists for lockout features that prevent necessary positioning or support of unauthorized rolls of web material relative to a given dispenser. In such a lockout system, in the event that there is an inconsistency between a registration component associated with a core of the roll and a mating registration portion associated with the hub or spindle of the dispenser, the roll of material will not be accepted into the dispenser in an operable manner thereby inhibiting use and/or proper support for dispensing of an unauthorized roll of web material.
- A further need exists for a lockout roll dispensing system that is relatively inexpensive to manufacturer, produce, and maintain in a useable condition, inhibits use of unauthorized rolls of web materials, and solves other problems associated with existing configurations. A still further need exists for a dispenser assembly roll of web material lockout system that can be quickly and conveniently implemented into existing or previously deployed dispenser assemblies and which includes separable elements that can be configured to designate rolls of web material as authorized to be dispensed with dispenser assemblies that have been reconfigured to include the lockout system. A need further exists for roll web material lockout systems that provide robust support of authorized materials to facilitate the sequential rotational dispensing of the web material from the bulk roll. A further need exists for rendering a dispenser assembly incapable of supporting those rolled web material rolls that do not include the mating registration element.

Continued axial translation ofinsert 504 relative tohub 502 indirection 570 allowsdistal end 528 ofhub 502 to deflect discrete retainers orfingers 550 in outward radial directions, indicated byarrow 576, untildiscrete projections 560 associated withfingers 550 seat or otherwise slideably cooperate withchannel 530 defined byhub 502 such thatinsert 504 is axially positioned relative tohub 502 and such thatdistal end 528 associated withpost 522 is oriented laterally outboard relative to insert 504. Althoughpost 522 extends throughinsert 504, it should be appreciated that thedistal end 528 ofpost 522 is oriented in the bore associated with the roll ofweb material 172 associated withinsert 504. Wheninsert 504 andhub 502 are engaged with one another such thatprojections 560 associated withfingers 550 are engaged withchannel 530 defined byhub 502, rotational interaction ofinsert 504 and the roll of web material associated therewith relative tohub 502 is provided in a manner that allows the roll of web material to be rotated but with limited free rotation therebetween after each dispense event. Such considerations mitigate instances of dispensing more web material than is desired and/or free spinning of the roll ofweb material 172 between dispense events. - Cooperation of one or more of
projections 560 with cavity orchannel 530 restricts axial translation ofinsert 504 relative tohub 502 when a respective roll of web material is associated therewith and without being acted upon by outside forces, such as a user's removal of remainder of a mostly consumed roll of web material or adiscrete insert 504 associated with a recently consumed or fully dispensed roll ofweb material 172. As shown inFig. 5 ,hub 502 and insert 504 cooperate with one another so as to define afirst bearing surface 580 and asecond bearing surface 582 that are formed between the respective adjacent radially facing surfaces ofhub 502 and insert 504.Bearing surface 580 ofroll lockout system 500 is radially neareraxial centerline 526 than bearingsurface 582. It should also be noted that in addition to the radial spacing of bearingsurfaces surface 580 and bearingsurface 582 are also offset relative to one another alongaxis 526. Such a construction provides stable rotational support betweeninsert 504, and a roll of web material associated therewith, and thehub 502 associated with the respective underlying dispenser assembly and/orrespective support arm 22, 122 associated therewith and as disclosed further above. Bearing surfaces 580, 582 further each provide a generally circumferential rotationally supported interaction betweenhub 502 and insert 504 when associated with one another and do so in a manner that offsets the rotational support betweenhub 502 and insert 504 from the axial indexing cooperation associated with the cooperation ofprojections 560 withchannel 530. Such considerations provide robust rotational support betweenhub 502 and insert 504 to better accommodate the mass of a full roll of web material when associated therewith. - It is appreciated that the construction and orientation of the plurality of retainers or
fingers 550 associated withroll lockout system 500 can similarly be provided in numerous configurations. As mentioned above, upon consumption of a discrete roll of web material associated withdispenser assembly 28 and supported bylockout system 500, user manipulation ofinsert 504 allowsfingers 550 to deflect in respective outward radial directions, indicated byarrows 576, to facilitate the removal or disengagement of adiscrete insert 504 from the relativeunderlying hub 502 to accommodate replacement, replenishment, or re-loading of dispenser assembly equipped withhub 502 with a roll of web material having aninsert 504 associated with its bore and thereby correlating to an authorized respective roll of web material. - It is further appreciated that
roll lockout system 500 can be configured with other radially spaced and/or numbers of deflectable retainers or fingers and/or numbers and constructions other than that which is shown in the drawings. For instance, it is appreciated thatfingers 550 may be provided in more offewer fingers 550 than shown in the figures, other radial shapes or sizes, and/or to haveprojections 560 associated therewith and/or configured to cooperate with a respective portion ofinsert 504 so as to facilitate the rotational cooperation therebetween, the axially indexed relative position therebetween, and do so in a manner that mitigates axial dissociation or translation ofinsert 504, and the roll of web material associated therewith, relative tohub 502, during use of the underlying dispenser assembly. It is envisioned that as few as twofingers 550 may be provided and may be provided to extend a similar or dissimilar circumferential distance aboutchannel 530 and be spaced about the circumference thereof so as to maintain the desired rotational cooperation betweenhub 502 and arespective insert 504 associated therewith and without negating the manually separable cooperation ofinsert 504 withpost 522 upon consumption or use of a discrete roll of discrete web material. As disclosed further below, it is appreciated that, due to the similarities in their size and constructions, insert 504 is preferably constructed to interchangeably cooperate with hubs or hub assemblies having constructions that differ fromhub 502. - Referring to
Figs. 2 ,4, and 5 ,body 538 ofinsert 504 ofroll lockout system 500 includes an overlappingportion 592 such thatbody 538 ofinsert 504 has a generally S or Z shaped cross-sectional shape as the shape or cross-section ofinsert 504 progresses betweenend 544 associated withfingers 550 andhub facing end 540 ofbody 538. Although shown as being generally axially aligned with bearingsurface 580 wheninsert 504 is engaged withhub 502, it is appreciated that overlappingportion 592 ofinsert 504 is may be disposed in alignment with bearingsurface 582 or disposed between bearingsurfaces portion 592 ofinsert 504 is disposed between bearingsurfaces axis 526 and the radial direction as indicated byarrows 576. As shown, the separation betweenadjacent fingers 550 extends between an open endproximate projections 560 and a closed end proximate overlappingportion 592 such that eachfinger 550 extends in a cantilevered manner relative to the remainder ofbody 538 from a position proximate overlappingportion 592. - Preferably overlapping
portion 592 is formed toward the hub directed side ofinsert 504 relative toaxis 526 and relative to end 544 thereof. That is to say, althoughinsert 504 could be constructed such that overlappingportion 592 be oriented axially outboard of each of bearingsurfaces portion 592 is preferably shaped and positioned to be axially aligned or overlapping in radial directions one of bearingsurfaces portion 592 is constructed to maintain the deflectable nature associated with operation offingers 550 relative tohub 502, facilitate initial alignment of aninsert 504 equipped roll of web material withhub 502, attain the desired engagement of a roll of web material with the dispenser, removal of any residual portion associated with a previously consumed roll of web material, and do not otherwise interfere with or detract from thedual bearing surface discrete inserts 504 andhub 502. -
Figs. 6-9 disclose aroll lockout system 600 according to yet another embodiment of the application. Likelockout system 500 as disclosed above,lockout system 600 includes ahub 602 that is constructed to selectively cooperate with an insert such asinsert 504 in the manner disclosed above. As such, like reference numbers are used hereafter with respect to the construction ofinsert 504. As disclosed above, insert 504 is constructed to cooperate with abore 607 of a roll ofweb material 609 such that, when disposed therein, insert 504 is preferably rendered non-removable from roll ofweb material 609 save for the depletion thereof and/or destruction of any residual portion of the respective roll of web material such thatinsert 504 can be considered reusable, recyclable, and/or disposable. - Unlike the
lockout system 500,hub 602 cooperates with a support arm or support arm assembly such thathub 602 is rendered movable relative thereto. As shown,hub 602 cooperates with a support assembly that includes asupport arm 606 and acarriage 608 that is engaged therewith.Support arm 606 is defined by abody 610 that is constructed to engage a housing such as housing 202 (Fig. 1 ) in a manner according to one or more of the methodologies disclosed above. Preferably,body 610 ofsupport arm 606 is constructed to snap-fittingly cooperate with the respecting housing such that a forward oriented hub supporting portion ofbody 610 is offset from the interior facing surfaces of the housing and such that roll ofweb material 609 can be supported byhub 602 whenhub 602 is engaged withsupport arm 606. - A
passage 612 is formed throughbody 610 ofsupport arm 606 and is shaped to cooperate with respective portions ofcarriage 608 andhub 602 associated therewith as disclosed further below. One ormore openings body 610 ofsupport arm 606 and are generally disposed aboutpassage 612. One or more handles ortabs body 610 relative topassage 612.Tabs support arm 606 and a respective core or cigar associated with a sufficiently depleted roll ofweb material 609 to assist with the selective separation betweenhub 602, the core or any portion of a spent roll ofweb material 609, or aninsert 504 that may be associated therewith during reloading of a dispenser assembly equipped therewith. - Referring to
Figs. 7 and8 ,carriage 608 is defined by abody 630 having a roll or insert facing surface orside 632 and a support arm facing surface orside 634. Apassage 636 and one ormore openings body 630 ofcarriage 608.Openings passage 636 such that each ofpassage 636 andopenings body 630 ofcarriage 608. As disclosed further below, such a construction maintains a relative rotational orientation ofhub 602 relative tocarriage 608 whenhub 602 is associated therewith and in a manner that accommodates selective axial translation ofhub 602 relative tocarriage 608 in the manner disclosed further below. - A
wall 644 is generally formed about a perimeter ofbody 630 and includes one ormore projections support arm 606. Acatch 654 is formed proximate the distal end of eachprojection Catches 654 andprojections respective openings support arm 606 such thatcarriage 608 snap fittingly cooperates therewith such thatcarriage 608 is positionally fixed relative to supportarm 606 when engaged therewith. A plurality of projections orarms arm facing side 634 ofcarriage 608 and are disposed radiallyproximate openings barb 672 is formed near the free ordistal end 674 of one or more ofarms Arms hub cavity 678 therebetween.Arms hub 602 withinhub cavity 678 and have an at-rest orientation whereinbarbs 672 overlap the radial footprint ofhub 602 oncehub 602 is position therein. As should be appreciated fromFig. 8 ,hub 602 is insertable intohub cavity 678 from a direction facingsupport arm 606 such that, once assembled, removal ofhub 602 fromhub cavity 678 in a direction toward the roll cavity of the dispenser cavity is prevented. As disclosed further below,hub cavity 678 is shaped to supporthub 602 such thathub 602 is axially moveable or slideable therein relative tocarriage 608. - Still referring to
Figs. 7 and8 ,hub 602 is defined by abody 680 having apost 682 and one ormore projections Body 680 ofhub 602 defines acavity 690 that is disposed between a portion ofpost 682 and generally bounded byprojections Cavity 690 is shaped to cooperate with a biasing device, such as aspring 692 or the like. When assembled, opposing ends ofspring 692 cooperate withcarriage 608 andhub 602 to urgehub 602 andcarriage 608 toward one another. When assembled, biasingdevice 692biases hub 602 relative tocarriage 608 andsupport arm 606 toward an orientation whereinpost 682 ofhub 602 passes throughpassage 636 ofcarriage 608 and extends axially beyondroll facing surface 632 ofcarriage 608. When oriented in such a position,projections hub 602 pass throughrespective openings body 630 ofcarriage 608 and similarly extend axially beyondroll facing surface 632 ofcarriage 608 such thatpost 682 andprojections respective insert 504 and a roll ofweb material 609 associated therewith. Such an orientation is shown inFig. 6 whereinpost 682 andprojections hub 602 are oriented in an exposed oraccessible orientation 696 available for interaction withinsert 504 and a respective roll ofweb material 609 associated therewith. - Referring to
Fig. 9 , when oriented in theaccessible orientation 696,post 682 defines a first bearing surface orinterface 700 associated with interaction withinsert 504 andprojections interface 702 associated with engaging arespective insert 504 having a construction suitable to allow operative rotational but axially fixed engagement therewith such that theprojections 560 associated withrespective fingers 550 are engaged with achannel 704 defined bypost 682. Overlappingportion 592 ofinsert 504 rotationally cooperates with an exterior surface ofpost 682 and a radially outward directed surface ofprojections insert 504. It is appreciated that the relative position and construction of bearingsurfaces portion 592 associated with the cooperation and engagement ofinsert 504 andhub 602 can be provided in any of the alternate relative constructions, relative to one another and/or each other, disclosed above with respect to the cooperation ofinsert 504 withhub 502. Regardless of the relative configuration therebetween, biasingdevice 692 provides sufficient force to tolerate the slideable association ofinsert 504 withhub 602 such thatprojections 560 defined byinsert 504 can achieve operative engagement withchannel 704 defined byhub 602 when an insert constructed for operative engagement withhub 602 is associated therewith. - If however a user attempts to associate or otherwise engage a roll of web material having an improperly configured insert with
hub 602, such action translateshub 602 in an axial or lateral direction, indicated byarrow 708, relative tocarriage 608 withinhub cavity 678 such thatpost 682 andprojections carriage 608, and against the bias ofspring 692, such thathub 602 is rendered no longer available or exposed for operative interaction with such an insert.Barbs 672 associated witharms hub 602 andcarriage 608 during such instances and are oriented to interact with astop 712 defined bybody 680 ofhub 602.Barbs 672 and stop 712 are configured and oriented to prevent continued lateral displacement ofhub 602 relative tocarriage 608 and to maintain the desired slideable association betweenpost 682 andprojections hub 602 withpassage 636 andopenings carriage 608, respectively. - During dissociation of the conflicting insert from interaction with
hub 602, biasingdevice 692 acts to returnhub 602 from retracted positions relative tocarriage 608 toward the exposed, available, or accessible orientation orconfiguration 696 as the conflicting insert is moved away from or otherwise dissociated from interaction withhub 602. As such, when an appropriately configuredinsert 504 is associated withhub 602, the interface therebetween provides a configuration having multiple bearing supports and a methodology that prevents use of dispenser assemblies equipped withhub 602 for use with rolls of web material having inserts that are improperly configured for suitable rotational interaction withhub 602 by physical movement ofhub 602 to positions wherein the hub is rendered unavailable for operational interaction with such inserts. - Therefore, a web material roll lockout assembly according to one embodiment of the present application discloses a hub that is constructed to be supported by a dispenser. An insert is constructed to rotationally cooperate with the hub when the insert is disposed in a bore of a roll of web material and the roll of web material is associated with the dispenser. A channel is formed in a radially outward oriented surface of the hub and positioned such that the channel is formed proximate an end of the hub. The assembly includes an insert that is constructed to removeably cooperate with the hub and has an overlapping portion formed between opposing ends of the insert. A plurality of projections are defined by the insert and constructed to limit axial translation between the insert and the hub when at least one of the plurality of projections is engaged with the channel and such that the overlapping portion of the insert improves flexibility associated with movement of the plurality of projections. A first rotational bearing surface and a second rotational bearing surface are defined between the insert and the hub when the at least one of the plurality of projections is engaged with the channel. The first rotational bearing surface and the second rotational bearing surface are positioned so that the overlapping portion of the insert is disposed therebetween.
- Another embodiment of the present application discloses a method of restricting rolls of web material that can be dispensed from a roll dispenser. The method includes providing a hub that defines an axis of rotation of a roll of web material associated with the roll dispenser. An insert is provided that has an outer diameter that is constructed to securely engage a bore of a roll of web material and has a radially inward directed shape that slideably cooperates with the hub. A portion of the insert is formed to overlap itself as the insert traverses from opposing ends thereof and such that, when the insert is engaged with the hub, cooperation of the insert and the hub restricts axial translation between the hub and the insert and accommodates rotation of the insert relative to the hub during rotation of a roll of web material. Engagement of a respective insert with the hub defines at least two bearing surfaces between the insert and the hub wherein each of the at least two bearing surfaces are offset in an axial direction from respective longitudinal ends of the insert and the hub and such that the overlapping portion of the insert is preferably disposed between the at least two bearing surfaces.
- A further embodiment of the present application discloses an insert for use in a roll web material dispenser assembly. The insert includes a body that extends between a first end and a second end of the insert. An outer surface of the body of the insert is shaped to be received in a roll of web material and an inner surface of the body of the insert is shaped to removeably cooperate with a hub associated with a dispenser and to define at least two bearing surfaces that are axially offset from one another when engaged with the hub. The insert includes a plurality of deflectable fingers that are associated with a first end of the body and a projection is associated with at least one of the plurality of deflectable fingers and oriented to engage a groove defined by the hub. The body defines an overlapping portion of the insert between the first end and the second end of the insert and is positioned between the at least two bearing surfaces.
- Another embodiment of the application discloses a web material roll lockout assembly having a support arm that is constructed to engage a dispenser housing. A carriage is engaged with the support arm and a hub is supported by the carriage and movable relative to the carriage between an exposed position wherein a portion of the hub is accessible and a retracted position wherein the portion of the hub is inaccessible. A biasing device is configured to bias the hub toward the exposed position and an insert is constructed to be disposed in a bore of a roll of web material and to slideably cooperate with the hub so that the hub engages the insert without translating the hub relative to the carriage to the retracted position.
- A further embodiment of the present application discloses a method of forming a web material lockout assembly. The method includes forming an insert so that an outer geometric shape allows the insert to be slideably received in a bore of a roll of web material and an inner geometric shape that is shaped to removeably cooperate with a hub supported by a dispenser. The hub is supported so that the hub is slideable relative to the dispenser so that the hub is unavailable for engagement if an insert having a different inner geometric shape is attempted to be associated therewith.
- A further embodiment of the present application discloses a web material dispenser lockout system that includes a support assembly that is constructed to cooperate with a dispenser housing. A hub slideably engages the support assembly so that the hub is movable between an extended position and a retracted position. A biasing device is engaged with the hub and oriented to bias the hub toward the extended position.
