TECHNICAL FIELD

The present disclosure generally relates to rolls of web material and to dispensers of rolled web material. More particularly, the disclosure relates to a spindle assembly to support a roll of web material in a dispenser; to a rolled web material dispensing assembly and to a method for inserting a roll of web material in a dispenser of rolled web material.

BACKGROUND

Several types of paper roll dispensers exist in the prior art that are used to gradually provide a user of the paper roll dispenser with different types of paper. The most common of these types of paper roll dispensers, dispenses paper items such as paper towels or toilet paper. Some of these paper rolls include a bushing provided in a cavity thereof, to interact with the mandrel of the dispenser. The bushing provided in the cavity of the roll can facilitate and improve roll replacement in the dispensers. However, the bushing might make the paper roll unusable in certain types of paper roll dispensers.

It could be advantageous to allow the use of paper rolls which include a bushing, in paper roll dispensers that are not originally configured to be used with such paper rolls.

Referring to the drawings, and more particularly toFIGS. 1 to 12, a first embodiment of a spindle assembly100is shown, for supporting a roll20of web material21—or web material roll20(as represented inFIG. 20)—in a dispenser10(or web material dispenser). The web material roll20defines a central cavity26of the roll20. Moreover, the web material roll20has a bushing30provided in its central cavity26. As it will be further detailed, the spindle assembly100comprises first and second spindle elements200,300(or a bushing-engaging member200and a spindle connection member300, or first and second roll support members200,300) configured to be assembled together (i.e. to be configured in an assembled configuration) thereby allowing use of the web material roll20with the bushing30in the web material dispenser10. The term “use” should be understood as referring to the delivery or dispensing of the web material21via a dispenser opening (not represented) of the web material dispenser10. The spindle assembly100may also be referred to as a “spindle adaptor”, since it allows replacing the conventional spindle (or mandrel) of dispensers for instance configured to receive web material rolls without a bushing provided in their cavity, with the “spindle assembly” or “spindle adaptor”, so as to allow receiving rolls provided with a bushing inserted therein.

Web Material Dispenser and Web Material Roll

Referring to the drawings, and more particularly toFIGS. 12, 19 and 21 to 23, the dispenser10(or web material dispenser10) is configured to dispense rolled web material21. The dispenser10comprises a first (or left) side12and a space-apart second side16(or right side), the first and second sides12,16defining at least partially a dispenser cavity19in between, to receive the roll20of web material21. The roll of web material21can be a roll of hygienic paper for example.

In the embodiment shown, the first and second sides12,16are substantially parallel to each other and extend, for instance, in substantially vertical planes. First and second guiding rails14,18are formed respectively in the first and second sides12,16. The rails can take other shapes and configuration, as long they allow receiving opposite ends of the spindle assembly100. For instance, and without being limitative, the dispenser10could comprise first and second substantially U-shaped receiving portions mounted respectively to the first and second sides12,16dimensioned and shaped to receive the opposite ends of the spindle assembly100. Elongated slots could also be formed in the first and second sides12,16communicating with the dispenser cavity19and be shaped and dimensioned to receive the opposite ends of the spindle assembly100.

Referring toFIGS. 8, 11, 12 and 20, the roll20of web material21illustrated is a toilet/hygienic paper roll and has a central axis X1. The roll20of web material has first and second opposed extremities22,24. The rolled web material21defines two opposed lateral sides25,28that extend, in this embodiment, substantially parallel to each other in substantially vertical planes. In other words, in the embodiment shown, the opposed lateral sides25,28extend substantially perpendicularly to the central axis X1.

In the illustrated embodiment, the roll20of web material further comprises a hollow central core23inserted in the central cavity26defined by the rolled web material21, typically made of cardboard, around which the web material21is rolled. Even though the hollow central core23might be useful to help and maintain the shape and dimensions of the central cavity26of the web material roll20, it could be conceived a web material roll20in which the central cavity26would only be defined by the rolled web material21. Such rolls of web material are sometimes referred to as “coreless” rolls.

The roll20of web material can be a toilet paper roll, a hand towel paper roll, or any other type of rolled paper or more globally any other type of rolled web material product.

The web material roll20illustrated is a toilet/hygienic paper roll, comprising the bushing30inserted therein, provided in the roll's central cavity26, toward the first extremity22, as best shown inFIG. 20. In the embodiment shown, the central cavity26has a cross-section27(FIG. 8) substantially constant along the central axis X1. The central cavity26is shaped and dimensioned for the bushing30to be at least partially inserted therein. This embodiment of a bushing is only one of many possible other configurations of bushings that can be used according to the present invention. Different possible embodiments of the bushing30are described in CA 3.036.028 filed by the Applicant. In this example, a single bushing is inserted at one of the extremities22,24of the roll20of web material, but in other embodiments, it is possible to have two bushings, one bushing being inserted in each of the two extremities of the roll of web material.

When inserted into the roll20of web material, the bushing30defines a central axis that substantially coincides with the central axis X1of the roll20. In other words, when the bushing30is inserted in the roll20of web material, the central axis of the bushing30is preferably substantially coaxial with the central axis X1of the roll20of web material.

Referring toFIGS. 8 to 12, the bushing30comprises a body32sized, shaped and configured to be fitted at least partially into the central cavity26of the roll20. The bushing30has first and second ends34,36. When the bushing30is fitted in the central cavity26of the roll20, the first end34is proximate to the first extremity22of the roll20.

It is thus understood that the bushing30is configured to be mounted in at least one of the extremities of the roll20by being snugly fitted into the central cavity26thereof, so that the bushing30cannot rotate relative to the roll20around the central axis X1once in place.

The bushing30may further comprise an outside collar38extending from and encircling the first end34. As illustrated inFIG. 8, when the bushing30is inserted into the roll20of web material, the outside collar38abuts the first lateral side25of the roll20.

As best shown inFIGS. 9 and 10, the bushing30may further comprise a wall40that is configured to extend, when the bushing30is at least partially inserted into the central cavity26of the roll20of web material, across the central cavity26of the roll20. The wall40includes an opening or hole42. In the embodiment shown, the wall40of the bushing30is configured to be at least partially broken, as will be described below, when the first spindle element200is removed from the roll20of web material.

As best shown inFIGS. 9 and 10, the body32of the bushing30has an inner surface43having a portion located near the first end34of the bushing30and defining a first bearing surface or contact surface44. This first bearing surface44has a first diameter d1(identified inFIG. 10). The surface of the opening42formed in the wall40defines a second bearing surface or contact surface46having a second diameter d2, the second diameter d2being smaller than the first diameter d1. In this embodiment, the bushing30is fixedly inserted in the roll. In the embodiment shown, the first spindle element200or bushing-engaging member200of the spindle adaptor/assembly100can be rotatable with respect to the bushing30(and with respect to the web material roll20provided with the bushing30) about the central axis X1. For instance, the first and second bearing surfaces44,46contact the bushing-engaging member200when the bushing-engaging member200and the bushing30are rotated relative to each other about the central axis X1. The first spindle element200of the spindle assembly100can thus be rotated about the first axis X1with respect to the roll20provided with the bushing30.

Depending for instance on the pulling force exerted on the web material21and/or on the material forming the bushing30and/or the material forming the first spindle element200, the first spindle element200can be in frictional engagement with the bushing30so that the first spindle element200be substantially fixedly inserted in the bushing30, with the wider section230(or proximal portion230—identified inFIG. 1) being in contact with the inner surface of the bushing30near the first end34, and the narrower section250(also identified inFIG. 1) being in contact with the edge of the bushing's wall40, the edge of the wall40delimiting the bushing's opening/hole42. The assembly formed by the bushing30and the first spindle element200of the spindle assembly100can thus be fixed with respect to the roll20(i.e. the assembly of the bushing30and the first spindle element200can be prevented from rotating relative to the roll20around the central axis X1once in place in the central cavity26), in which case the roll rotates in the dispenser via a first dispenser mounting portion210of the first spindle element200(identified inFIG. 1) on one side, and via a second dispenser mounting portion310of the second spindle element300on the other side, as will be described in more detail below.

First Spindle Element: Bushing-Engaging Member

Referring toFIGS. 1 to 6, the first spindle element200(or first roll-supporting member200or bushing-engaging member200) defines a central axis extending substantially parallel to the central axis X1of the web material roll20(for instance substantially coinciding with the central axis X1of the roll20of web material) when the first spindle element200is at least partially engaged in the bushing30and/or in the central cavity26of the roll20.

The first spindle element200has a first end202(or outer end, in that it is configured to be located outwardly with regards to the central cavity26of the roll20, or proximal end, with regards to the first side12of the dispenser10) and an opposed second end204(or inner end, with regards to the central cavity26of the roll20, or distal end, with regards to the first side12of the dispenser10) and comprises a first dispenser mounting portion210and a bushing mounting portion220(or roll-supporting portion or bushing-engaging portion220).

The first dispenser mounting portion210is removably mountable to the first side12of the dispenser10, and the bushing mounting portion220(or roll-supporting portion or bushing-engaging portion220) is sized and configured to fit in and at least partially connect to the bushing30provided in the roll20of web material.

First Dispenser Mounting Portion

The first dispenser mounting portion210(or first dispenser-connecting portion) forms the first end202(or outer end) of the first spindle element200and is removably mountable to the first side12of the dispenser10.

Optionally, the first dispenser mounting portion210comprises a first shaft212receivable in the first guiding rail14of the first side12or slidably positionable in the first guiding rail14of the first side12. The first shaft212is substantially cylindrical.

The first dispenser mounting portion210further comprises a first blocking disk214(or first outer member) forming at least partially the first end202of the first spindle element200. The first shaft212extends between the first blocking disk214and the bushing mounting portion220. The first blocking disk214presents a cross-section greater than a cross-section of the first shaft212so that, when the first shaft212is received in the first guiding rail14, as illustrated inFIG. 12, the first shaft212cannot be moved (for instance cannot be translated) along the central axis X1of the roll20) for the first dispenser mounting portion210to be removed from the first side12of the dispenser10. In other words, the first blocking disk214is configured to abut against a portion of the first side12of the dispenser10(for instance to abut against a portion of an outer face of the first side12, considered with respect to the dispenser cavity19of the web material dispenser10) when the first spindle element200is mounted to the first side12and is translated inwardly along a direction substantially parallel to the central axis X1of the roll20. Even though in the embodiment shown, as represented inFIG. 12, the first blocking disk214extends proximate to the outer face of the first side12of the dispenser10when the first spindle element200is mounted thereto, a first spindle element200dimensioned so that the first blocking disk214would be spaced apart from the first side12of the dispenser10when mounted thereto could also be conceived. A first spindle element200having no first blocking disk214could also be conceived.

It is appreciated that the shape and the configuration of the first dispenser mounting portion210, and more particularly the shape and configuration of the first shaft212and the first blocking disk214, can vary from the embodiment shown.

In the second embodiment of the spindle assembly700represented inFIGS. 13 to 19, the first spindle element800(or bushing-engaging member800) also comprises a first dispenser mounting portion810and a bushing-engaging portion820. The first dispenser mounting portion810further comprises a first spacing element811removably mounted to the first shaft812. The first spacing element811is shaped and dimensioned to increase a cross-section of the part of the first dispenser mounting portion810configured to be mounted to the first side12(for instance the part of the first dispenser mounting portion810configured to be at least partially received in the first guiding rail14) for the first dispenser mounting portion810to be adapted to web material dispensers having first guiding rails of different dimensions. The first spacing element811is shaped and dimensioned to surround at least partially an outer periphery of the first shaft812. The first spacing element811can be made in a material different from a material forming the first shaft812, or in a same material. The first spacing element811is shaped, dimensioned and configured not to prevent the first dispenser mounting portion810from being rotated with respect to the first side12of the dispenser10, upon exertion of a pulling force on the web material21of the web material roll20(i.e. on a free end of the web material roll20). In some embodiments (not represented), the dispenser might be configured to receive upper and lower web material rolls20in a superposed configuration (i.e. the upper web material roll is engaged with upper portions of the first and second sides of the dispenser, whereas the lower web material roll is engaged with lower portions of the first and second sides). The dispenser might further comprise a restraining assembly configured to maintain the upper web material roll engaged with the upper portions of the first and second sides until the lower web material roll is empty; once the lower web material roll is empty, the upper web material roll is driven downwardly for its web material to be dispensed. The first spacing element811might thus be shaped and dimensioned so as to prevent the upper web material roll from being driven downwardly before the lower web material roll is empty.

The bushing mounting portion220(or roll-supporting portion or bushing-engaging portion) comprises, inwardly along the central axis (with regards to the roll receiving cavity19or dispenser cavity19of the dispenser10), a proximal portion230proximate to the first dispenser mounting portion210, a central portion240, a distal portion250and a free end260. In the embodiment shown, a cross-section of the bushing-engaging portion220decreases from the proximal portion230towards the free end260.

In the embodiment shown, the proximal portion230and the distal portion250are both substantially cylindrical. The proximal portion230has a cross-section232that is greater than a cross-section252of the distal portion250.

The central portion240is thus located between the proximal portion230and the distal portion250. For instance, the central portion240has a substantially truncated cone shape: a cross-section of the central portion240decreases from a first extremity (or proximal extremity) proximate to the proximal portion230towards a second extremity (or distal extremity) proximate to the distal portion250.

The first spindle element200further comprises a head270(for instance a tapered head270) bulging at the free end260. In other words, the head270is tapered and has a cross-section decreasing from a first extremity (or outer extremity, with regards to the roll receiving cavity19of the dispenser10) proximate to the distal portion250towards an opposed second extremity (or inner extremity). A shoulder272(FIG. 10) is thus formed between the bulging tapered head270and the distal portion250.

The bushing mounting portion220defines a rod receiving cavity278. In the embodiment shown, the rod receiving cavity278extends at least partially along the proximal portion230, the central portion240, the distal portion250and the free end260, and the rod receiving cavity278opens onto the free end260. The bushing mounting portion220further comprises first and second blocking windows234,236(or first and second blocking members) formed in a peripheral wall of the proximal portion230. Optionally, the first and second blocking members234,236comprise substantially rectangular windows formed at two distinct longitudinal positions—considered along the central axis X1when the spindle assembly100is mounted to the web material roll20—of the bushing mounting portion220.

It is appreciated that the shape and the configuration of the bushing mounting portion210, and more particularly the shape, the configuration and the relative location of the proximal portion230, the central portion240, the distal portion250, the head270forming the free end260and the rod receiving cavity278formed therein can vary from the embodiment shown. The shape, number, configuration and location of the first and second blocking windows234,236might also vary from the embodiment shown. For instance, non-through recesses could be formed in the peripheral wall of the proximal portion230.

For instance, as represented inFIG. 13, the bushing-engaging portion820of the first spindle element800also comprises first and second blocking windows834,836formed in the peripheral wall of the proximal portion830. The first spindle element800further comprises visual indications proximate the first and second blocking windows834,836(for instance numerals).

Connection Assembly: Assembling Rod

In the embodiment shown, the spindle assembly100further comprises a connection assembly configured to connect together the first and second spindle elements200,300when configured in the assembled configuration.

The connection assembly firstly comprises an assembling rod400of the first spindle element200extending from the free end260of the bushing mounting portion220.

The assembling rod400comprises a free end402forming the second end204(or inner end or distal end, considered with respect to the first side12of the web material dispenser10) of the first spindle element200. Optionally, the free end402has a substantially cylindrical shape and extends in a direction substantially parallel to the central axis X1of the roll20, when the first spindle element200is engaged in the central cavity26of the roll20. The free end402of the assembling rod400has a cross-section403smaller than the cross-sections232,252of the proximal portion230and the distal portion250of the bushing mounting portion220.

The assembling rod400further comprises a proximal part404(or mounting portion) received in the rod receiving cavity278formed in the bushing mounting portion220, so that only the free end402of the assembling rod400is visible from the outside of the first spindle element200and protrudes from the head270of the bushing mounting portion220. As represented inFIGS. 9 and 10, the proximal part404comprises a mounting base406optionally having a substantially truncated shape, for the mounting base406to substantially fit in the portion of the rod receiving cavity278formed in the central portion240of the bushing mounting portion220. The mounting base406further comprises at least a blocking tongue408(or blocking piece) having a blocking end409dimensioned to be selectively received in each of the first and second blocking windows234,236(or to cooperate with the first and second blocking members) of the bushing mounting portion220.

It is thus understood that the assembling rod400is configurable into a first configuration (or retracted configuration), as represented in solid lines inFIG. 2, in which the blocking end409of the blocking tongue408is received in the first blocking window234. When configured in the first configuration (or retracted configuration), the free end402of the assembling rod400is at a first distance410from the first dispenser mounting portion210(the first distance410corresponding to the distance between a distal extremity407of the free end402and the first blocking disk214). The assembling rod400is further configurable into a second configuration (or extended configuration), as represented in dotted lines inFIG. 2, in which the blocking end409of the blocking tongue408is received in the second blocking window236. When configured in the second configuration (or extended configuration), the free end402of the assembling rod400is at a second distance420from the first dispenser mounting portion210. The second distance420is greater than the first distance410. In some embodiments, the second distance420is less than about 95% of the first distance410. In some other embodiments, the second distance420is less than about 92% of the first distance410. In yet some other embodiments, the second distance420is equal to or smaller than about 90% of the first distance410.

It is thus understood that the first blocking window234and the blocking tongue408, on the one hand, and the second blocking window236and the blocking tongue408, on the other hand, form first and second blockers to block the assembling rod400respectively in the first and second configurations. By removing the blocking tongue408from one of the first and second blocking windows234,236, displacing the assembling rod400in the rod receiving cavity278, and placing the blocking tongue408in the other one of the first and second blocking windows234,236, it is easy to configure the assembling rod400from one of the first and second configurations to the other one of the first and second configurations.

Similarly, the first spindle element800of the spindle assembly700in accordance with the second embodiment also comprises an assembling rod1000configurable into first and second configurations (or retracted and extended configurations). The assembling rod1000comprises a blocking tongue1008(FIGS. 17 and 18) selectively engageable in the first and second blocking windows834,836. The use of visual indicators proximate to the first and second blocking windows834,836allows to easily identify in which of the first and second configurations the assembling rod1000is configured.

It is appreciated that the shape, the configuration, and the location of the first and second blockers can vary from the embodiments shown, as long as they allow an easy axial or longitudinal positioning and blocking of the assembling rod400,1000with regards to the first mounting portion210,810. It could also be conceived a first spindle element200,800in which the assembling rod400,1000could be configurable into more than two discrete positions.

Moreover, it is appreciated that the shape and the configuration of the assembling rod400,1000and more particularly the shape and the configuration of the free end402,1002and the proximal part404,1004, can vary from the embodiment shown. For instance, as represented inFIGS. 17 and 18, recesses1001can be formed in the assembling rod1000, to reduce a weight of the first spindle element800and/or to ease the manufacturing of the first spindle element800.

Additional Features of the First Spindle Element

The first spindle element200further comprises a first abutting portion280(or first handling portion or first insertion-limiting portion or first engagement-limiting portion) located between the bushing mounting portion220and the first dispenser mounting portion210. In other words, the first abutting portion280and the first blocking disk214form two axially spaced enlargements at the first dispenser mounting portion210. It is appreciated that the shape and the number of the axially spaced enlargements can vary from the embodiment shown.

Optionally, the first abutting portion280is substantially cylindrical and has a cross-section282greater than the cross-section232of the proximal portion230, and thus greater than the cross-section252of the distal portion250. The cross-section282of the first abutting portion280is greater, in the embodiment shown, than a cross-section of the first blocking disk214. The cross-section282of the first abutting portion280is also greater that the cross-section27of the central cavity26, so that the first abutting portion280abuts against the lateral side25of the roll20when the assembling rod400is engaged into the bushing30provided in the central cavity26of the roll20. The first abutting portion280thus limits the engagement of the first spindle element200into the bushing30provided in the central cavity26of the roll20. Optionally, when the bushing30comprises the outside collar38configured to limit the insertion of the bushing30into the central cavity26, the first abutting portion280of the first spindle element200abuts against the outside collar38when the first spindle element200is inserted into the bushing30. In other words, the outside collar38is sandwiched between the first abutting portion280and the web material21(the first lateral side25of the web material roll20, in the embodiment shown).

Grapping recesses284, for instance substantially trapezoidal, are formed in the first abutting portion280, that are configured to ease the handling of the first spindle element200.

Optionally, a recess (or groove or peripheral recess)274is formed in the bushing mounting portion220of the first spindle element200, behind the head270. In other words, the recess274is formed between the distal portion250and the head270. The recess274extends along at least a portion of an outer periphery of the bushing mounting portion220, optionally along substantially the entirety, i.e. along all of the outer periphery of the bushing mounting portion220. As shown, the recess274can define a substantially truncated portion extending between a front end of the distal portion250and a rear end of the head270. In other words, the recess274is shaped and dimensioned so that the cross-section of the bushing mounting portion220regularly decreases between the front end of the distal portion250and the rear end of the head270. It is however appreciated that the shape and the dimensions of the recess274can vary from the embodiment shown.

The recess274is configured so that, when the first spindle element200is removed from the roll20of web material with the bushing30inserted therein, the wall40is at least partially received in the recess274. Thus, the abutment surface of the substantially vertically extending face formed between the front end of the distal portion250and the tapered head270(i.e. at the shoulder272formed between the bulging head270and the distal portion250) against the wall40of the bushing30is increased. Consequently, breaking of the wall40of the bushing30upon removal of the first spindle element200is facilitated. In other words, the recess274eases breaking of the wall40when the first spindle element200is forced out of the bushing30.

Moreover, as represented for instance inFIGS. 9 and 10, the bushing mounting portion220further comprises a blocking protrusion276(comprising for instance a blocking ring) mounted to the front end of the distal portion250. The blocking protrusion276extends from an outer surface of the bushing-engaging portion220(an outer surface of the distal portion250thereof, in the embodiment shown). The blocking protrusion276—or peripheral protrusion—extends along at least a portion of an outer periphery of the distal portion250. Optionally, the blocking protrusion276extends along substantially the entirety of the outer periphery of the distal portion250. The blocking protrusion276might be integrally formed with the bushing mounting portion220, and more particularly with its distal portion250. It is appreciated that the shape and the dimensions of the blocking protrusion276can vary from the embodiment shown.

It is thus understood that, considered along the central axis of the bushing mounting portion220of the first spindle element200towards the free end260, an outer diameter of the bushing mounting portion220increases from the cross-section252of the distal portion250to the cross-section of the blocking protrusion276. Then the cross-section of the bushing mounting portion220decreases in the recess274and then increases when passing the shoulder272defined between the distal portion250and the tapered head270.

The blocking protrusion276is configured to limit the engagement of the first spindle element200in the bushing30: the blocking protrusion276forms a longitudinal blocker to cooperate with the wall40of the bushing30so as to ensure that, once the first spindle element200is introduced in the bushing30, the first and second bearing surfaces44,46of the bushing30are adequately arranged with regards to the first spindle element200(and more particularly with regards to the proximal portion230and the distal portion250of the bushing mounting portion220), thus resulting in an inadequate dispensing of the web material.

It is appreciated that the shape, the configuration, the relative arrangement and the number of blocking protrusion and peripheral recess can vary from the embodiment shown. For instance, as represented inFIG. 14of the second embodiment of the spindle assembly700, a plurality of axially spaced peripheral recesses874,875(two, in the embodiment shown) can be formed in the bushing-engaging portion820of the first spindle element800.

Construction of the First Spindle Element

As shown inFIGS. 5 and 6, the first spindle element200might be composed of a plurality of distinct elements secured together. For instance, the first spindle element200is composed of three distinct elements, at least some of them being partially hollow, connectable together (for instance removable mountable to each other) so as to form the rod receiving cavity278when assembled together.

In the embodiment shown, the first spindle element200comprises a first piece201forming the bushing mounting portion220and a portion of the first abutting portion280. The first spindle element200further comprises a second piece203forming a complementary portion of the first abutting portion280and the first dispenser mounting portion210. The first and second pieces201,203are detachably mountable to each other, for instance with closing tongues formed on the second piece203that are configured to be received in closing windows formed in a portion of the first piece201, optionally configured to form a peripheral wall of the first abutting portion280. The first spindle element200further comprises a third piece205forming the assembling rod400.

The present disclosure might also concern a kit for forming a first spindle element200, the kit comprising the first, second and third pieces201,203,205. To form the first spindle element200, the third piece205is firstly introduced in the rod receiving cavity278formed in the first piece201, via an extremity of the first piece201opposed to the free end260. Then the second piece203is secured to the first piece201so as to maintain the assembling rod400in the rod receiving cavity278. The kit might further comprise the piece(s) forming the second spindle element300.

It is appreciated that the shape and the configuration of the first spindle element200, and for instance the shape, configuration, cooperation and number of pieces composing the first spindle element200can vary from the embodiment shown.

Second Spindle Element: Spindle Connection Member

Referring toFIGS. 1 to 6, the second spindle element300of the spindle assembly100(or spindle connection member300or second roll-supporting member300) defines a central axis extending substantially parallel to the central axis X1of the web material roll20(for instance substantially coinciding with the central axis X1of the web material roll20when the second spindle element300is at least partially engaged in the central cavity26of the roll20via the second extremity24and mounted to at least one of the second extremity24of the web material roll20and the first spindle element200. It is understood that, in particular depending on the shape and dimensions of the first and second spindle elements200,300, and depending on whether the second spindle element300is directly mounted to the first spindle element200, the central axis of the second spindle element300might be inclined with respect to the central axis X1of the web material roll20when the second spindle element300is at least partially engaged in the central cavity26of the web material roll20. In other words, depending on the shape and dimensions of the first and second spindle elements200,300, a portion of a weight of the web material roll20supported by the first spindle element200can differ. In some embodiments, the first spindle element200can directly support a major part of the weight of the web material roll20.

The second spindle element300has a first end302(or outer end, with regards to the central cavity26of the web material roll, or a proximal end, considered with regards to the second side16of the dispenser10, or a dispenser-mounting end) and an opposed second end304(or inner end, or distal end or first spindle element-engaging end) and comprises a second dispenser mounting portion310and a connecting portion320mountable or connectable to at least one of the second extremity24of the roll20and the first spindle element200. Even though in the different figures (for instanceFIGS. 11 and 12) the second spindle element300is in contact with the roll20of web material, it could be conceived a spindle assembly wherein the second spindle element would not contact the roll of web material when connected to the first spindle element and/or engaged with the dispenser. The connecting portion320extends from the second dispenser mounting portion310. The second dispenser mounting portion310is removably mountable to the second side16of the dispenser10.

Second Dispenser Mounting Portion

The second dispenser mounting portion310(or second dispenser-connecting portion) of the second spindle element300forms at least partially the first end (or outer end or proximal end)302of the second spindle element300and is removably mountable to the second side16of the dispenser10.

Optionally, the second dispenser mounting portion310comprises a second shaft312receivable in the second guiding rail18of the second side16or slidably positionable in the second guiding rail18of the second side16. The second shaft312is substantially cylindrical.

The second dispenser mounting portion310further comprises a second blocking disk314(or second outer member) forming at least partially the first end302of the second spindle element300. The second shaft312extends between the second blocking disk314and the connecting portion320. The second blocking disk314presents a cross-section greater than a cross-section of the second shaft312so that, when the second shaft312is received in the second guiding rail18, as represented inFIG. 12, the second shaft312cannot be moved (for instance cannot be translated) along the central axis X1of the roll20for the second dispenser mounting portion310to be removed from the second side16of the dispenser10. In other words, the second blocking disk314is configured to abut against a portion of the second side16of the web material dispenser10(for instance to abut against a portion of an outer face of the second side16, considered with respect to the dispenser cavity19of the web material dispenser10) when the second spindle element300is mounted to the second side16and is translated inwardly along a direction substantially parallel to the central axis X1of the roll20. Even though in the embodiment shown, as represented inFIG. 12, the second blocking disk314extends proximate to the outer face of the second side16of the dispenser10when the second spindle element300is mounted thereto, a second spindle element300dimensioned so that the second blocking disk314would be spaced apart from the second side16of the dispenser10when mounted thereto could also be conceived. A second spindle element300having no second blocking disk314could also be conceived.

It is appreciated that the shape and the configuration of the second dispenser mounting portion310, and more particularly the shape and configuration of the second shaft312and the second blocking disk314(or second outer member), can vary from the embodiment shown.

In the second embodiment of the spindle assembly700represented inFIGS. 13 to 19, the second spindle element900(or spindle connection member900or second roll-supporting member900) also comprises a second dispenser mounting portion910and a connecting portion920. The second dispenser mounting portion910further comprises a second spacing element911removably mounted to the second shaft912. The second spacing element911is shaped and dimensioned to increase a cross-section of the part of the second dispenser mounting portion910configured to be mounted to the second side16(for instance the part of the second dispenser mounting portion910configured to be at least partially received in the second guiding rail18) for the second dispenser mounting portion910to be adapted to web material dispensers having second guiding rails of different dimensions. The second spacing element911is shaped and dimensioned to surround at least partially an outer periphery of the second shaft912. The second spacing element911can be made in a material different from a material forming the second shaft912, or in a same material. Similarly to the above-described first spacing element811, the second spacing element911is shaped, dimensioned and configured not to prevent the second dispenser mounting portion910from rotated with respect to the second side16of the dispenser10, upon exertion of a pulling force on the web material21of the web material roll20(i.e. on the free end of the web material roll20) and/or to prevent the upper web material roll from being driven downwardly before the lower web material roll is empty, in the above-mentioned embodiment in which the dispenser is configured to receive the upper and lower web material rolls in a superposed configuration.

In the embodiment shown, the connection assembly of the spindle assembly100further comprises the connection portion320configured to connect together the first and second spindle elements200,300when configured in the assembled configuration.

As illustrated, in the embodiment shown, the connection portion320comprises an assembling sleeve500defining an assembling cavity510to receive the assembling rod400of the first spindle element200for the first and second spindle elements200,300to be connected together when configured in the assembled configuration, thereby allowing use of the roll20of web material with the bushing30therein in the dispenser10. It could also be conceived a second spindle element300having a connection portion320that would be configured to be only or additionally mountable to the second extremity24of the roll20. In other words, the assembling rod400and the connection portion320form together the connection assembly of the spindle assembly100configured to connect together the first and second elements200,300of the spindle assembly100when configured in the assembled configuration.

Optionally, the assembling cavity510is substantially cylindrical and defines a central axis. In some embodiments, the central axis of the assembling cavity510substantially coincides with the central axis X1of the web material roll20when the second spindle element200is at least partially engaged in the central cavity26.

As shown inFIG. 7, in the first embodiment of the spindle assembly100, the assembling sleeve500has an inner surface512and at least one fitting rib514radially extending from the inner surface. The fitting rib514is configured to further secure the first and second spindle elements200,300together, when the assembling rod400is received in the assembling cavity510(i.e. when the first and second spindle elements200,300are configured in an assembled configuration).

The plurality of fitting ribs514protruding inwardly—considered with respect to the assembling cavity510—from the inner surface512of the assembling sleeve500are shaped and dimensioned to form axial couplers of the assembling sleeve500and the assembling rod400. In other words, the plurality of fitting ribs514protruding inwardly from the inner surface512of the assembling sleeve500are shaped and dimensioned to axially couple together the assembling rod400and the assembling sleeve500upon translation along a direction substantially parallel to a longitudinal axis of the spindle assembly100(for instance upon translation along a direction substantially parallel to the central axis X1of the web material roll20) of one of the bushing-engaging member200and the spindle connection member300when configured in the assembled configuration.

Moreover, the plurality of ribs514protruding inwardly—considered with respect to the assembling cavity510—from the inner surface512of the assembling sleeve500are shaped and dimensioned to form angular couplers between the assembling sleeve500and the assembling rod400. In other words, the plurality of ribs514protruding inwardly from the inner surface512of the assembling sleeve500are shaped and dimensioned to angularly couple together the assembling rod400and the assembling sleeve500upon rotation about of the longitudinal axis of the spindle assembly100(for instance upon rotation about the central axis X1of the web material roll20) of one of the bushing-engaging member200and the spindle connection member300when configured in the assembled configuration.

Other axial and/or angular couplers of the assembling rod400and the assembling sleeve500could be conceived.

For instance, in the second embodiment of the spindle assembly700, as represented for instance inFIG. 14, a connection recess1003is formed in an outer surface1005of the assembling rod1000. The connection recess1003is configured to cooperate with a coupling protrusion921protruding from an inner surface1112of the assembling sleeve1100of the second spindle element900. In other words, the connection recess1003and the coupling protrusion921are engageable together to connect the first and second spindle elements800,900when configured in the assembled configuration.

In the embodiment shown, the connection recess1003comprises an annular groove formed in the outer surface1005of the assembling rod1000, at the free end1002thereof. For instance, the connection recess1003extends substantially along an entirety of an outer periphery of the free end1002of the assembling rod1000.

In the embodiment shown, the coupling protrusion921is substantially bendable (for instance by being made in a material being substantially resilient and/or flexible) to be engaged in the coupling recess1003upon insertion or engagement of the assembling rod1000in the assembling cavity1110defined by the assembling sleeve1100. Moreover, the bending of the coupling protrusion921further allows the disengagement of the assembling rod1000from the assembling cavity1110upon translation of the first and second spindle elements800,900along opposed directions. The coupling protrusion921and the coupling recess1003thus form together another possible embodiment of the axial coupler of the spindle assembly700.

In the embodiment shown, the coupling protrusion921and the coupling recess1003are configured to generate, upon engagement of the coupling protrusion921in the coupling recess1003, an audible indication of a proper configuration of the bushing-engaging member800and the spindle connection member900in the assembled configuration. For instance, the audible indication is a clicking sound.

It could also be conceived a coupling recess that would only extend along a portion of the outer periphery of the outer surface of the assembling rod so that the coupling recess and the coupling protrusion would also form an angular coupler of the spindle assembly.

It is appreciated that the shape, the configuration, and the location of the axial and angular couples can vary from the embodiments shown.

Referring back toFIGS. 1 to 12of the first embodiment of the spindle assembly100, the assembling sleeve500has a length502and the assembling cavity510extends partially along the length502of the assembling sleeve500. In other words, the assembling cavity510has a length512smaller than the length502of the assembling sleeve500. Optionally, the length512of the assembling cavity510is more than about 30% of the length502of the assembling sleeve500, optionally more than about 40%, optionally more than about 50%.

The assembling cavity510has a cross-section516—considered between facing ribs514protruding inwardly from the inner surface512—corresponding substantially to the cross-section403of the free end402of the assembling rod400, for the assembling rod402to be fitted in and connected to the assembling cavity510(i.e. for the assembling rod400and the assembling sleeve500to be in frictional engagement together).

The assembling sleeve500further comprises a proximal portion522located between the portion of the assembling sleeve500in which the assembling cavity510is formed, and the second dispenser mounting portion310. Recesses and/or a central opening517might be formed in the proximal portion522, for instance to reduce a weight of the second spindle element300and/or to ease the manufacturing of the second spindle element300.

As shown, the assembling sleeve500has a cross-section520substantially constant along the length502of the assembling sleeve500. Optionally, the cross-section520is smaller than the cross-section27of the central cavity26, so that the assembling sleeve500does not support the central core23of the web material roll20when inserted in the central cavity26. However, an assembling sleeve500dimensioned and configured to at least partially support the central core23of the web material roll20(so that the second spindle element300supports at least partially the web material roll20) could be conceived.

It is appreciated that the shape and the configuration of the assembling sleeve500can vary from the embodiment shown.

Second Abutting Portion

The second spindle element300further comprises a second abutting portion330(or second handling portion or second insertion-limiting portion or second engagement-limiting portion) located between the assembling sleeve500and the second dispenser mounting portion310. In other words, the second abutting portion330and the second blocking disk314form two axially spaced enlargements at the second dispenser mounting portion310. It is appreciated that the shape and the number of the axially spaced enlargements can vary from the embodiment shown.

Optionally, the second abutting portion330comprises an abutting disk332having a cross-section334greater than a cross-section of the second blocking disk314. The cross-section334of the second abutting disk332is also greater than the cross-section27of the central cavity26, so that the second abutting portion330abuts against the lateral side28of the roll20when the second spindle element300is engaged into the central cavity26of the web material roll20via the second extremity24. The second abutting portion330thus limits the engagement of the second spindle element300into the central cavity26of the roll20. It could also be conceived a second spindle element300that would be shaped and dimensioned for the second abutting portion330not to contact the roll20.

Construction

Optionally, the second spindle element300is made of a single partially hollow piece, but a second spindle element made of a plurality of distinct pieces assembled together, could be conceived. For instance, the second spindle element900of the second embodiment of the spindle assembly700is made of two pieces (i.e. the second spacing element911and the remaining of the second spindle element900).

Roll Dispensing Assembly

According to another aspect of the disclosure, there is provided a roll dispensing assembly600,1200comprising a roll20of web material21having first and second extremities22,24and defining a central cavity26provided with a bushing30, toward the first extremity22. The roll dispensing assembly600,1200further comprises a spindle assembly100,700according to the present disclosure, having first and second spindle elements200,300,800,900mountable respectively to the first and second extremities22,24of the roll20of web material.

Method

According to another aspect of the disclosure, there is provided a method for inserting a roll20of web material21in a dispenser10, the dispenser10having first and second sides12,16, and the roll20of web material21having first and second extremities22,24and defining a central cavity26provided with a bushing30, toward the first extremity22.

The method according to embodiments of the present disclosure may be carried out with a spindle assembly100,700as described above.

The method firstly comprises providing a spindle assembly100,700such as the ones described above, comprising first and second spindle elements200,300,800,900. The method then comprises, as represented inFIGS. 8 to 10, engaging the first spindle element200in the bushing30of the roll20of web material21.

The free end402of the assembling rod400is firstly introduced in the central cavity26of the roll20via the first extremity22. In the embodiment shown, the free end402of the assembling rod400is engaged in the bushing30, until the first abutting portion280abuts against the lateral side25of the web material roll20and against the outside collar38of the bushing30, in the embodiment in which the bushing30comprises an outside collar38.

While inserting the first spindle element200in the bushing30, the tapered head270is introduced in the opening42of the wall40and deforms/pivots the wall40of the bushing30. When the first spindle element200is fully engaged in the central cavity26, as shown inFIGS. 8 to 10, the free end402of the assembling rod400extends beyond the wall40of the bushing30, so that the wall40extends between the free end402and the proximal portion230of the bushing mounting portion220. In this configuration, the first and second bearing surfaces44,46of the bushing30, as shown inFIGS. 9 and 10, cooperate respectively with the outer surface of the proximal portion230and with the outer surface of the distal portion250. It is thus understood that the first diameter d1of the first bearing surface44and the second diameter d2of the second bearing surface46substantially correspond respectively to the cross-section232of the proximal portion230and to the cross-section252of the distal portion250. As shown, the second bearing surface46is kept at an adequate position of the distal portion250via the blocking protrusion276.

The method then comprises introducing the second spindle element300in the central cavity26of the roll20via the second extremity24. Optionally, the second end304(or inner end) of the second spindle element300is introduced in the central cavity26until the free end402of the assembling rod400reaches a proximal portion of the assembling cavity510, i.e. until the free end402abuts against the proximal portion522of the assembling sleeve500to configure the first and second spindle elements200,300in the assembled configuration. In the embodiment shown inFIG. 19, the method further comprises engaging the coupling protrusion921in the connection recess1003and/or comprises generating an audible indication (for instance a clicking sound) when the first and second spindle elements800,900are properly configured in the assembled configuration.

In the embodiment shown, the second end304of the second spindle element300is introduced in the central cavity26until the second abutting portion330abuts against the lateral side28of the roll of web material20. The spindle assembly100could also be used mounted onto smaller rolls of web material, in which case the second abutting portion330might not abut against the lateral side28of the web material roll20.

The method further comprises mounting (for instance removably) the first and second dispenser mounting portions210,310respectively to the first and second sides12,16of the dispenser10, as represented inFIG. 22. In the embodiment shown, the mounting of the first and second dispenser mounting portions210,310comprises sliding the first and second dispenser mounting portions210,310in the first and second guiding rails14,18formed in the first and second sides12,16of the web material dispenser10.

The web material21can thus be delivered to a user by grapping the free end of the web material21and rotating the roll20of web material in the dispenser10. Depending, for instance, on the pulling force exerted by the user, the first and second spindle elements200,300might be rotated respectively in the first and second guiding rails14,16, or remain fixed. Moreover, as mentioned above, depending also, for instance on the pulling force exerted by the user, the bushing-engaging member200might be rotated in the bushing30or remain fixed with respect to the web material20provided with the bushing30.

In the embodiment shown, as represented inFIG. 23, the web material dispenser10is shaped and dimensioned to receive two roll dispensing assemblies600in a vertically-superposed configuration. Other web material dispensers could be conceived that would be configured to receive one or more roll dispensing assemblies600,1200in accordance with the present disclosure.

The spindle assembly100,700in accordance with the present disclosure can be used to support different types of web material rolls, such as web material rolls having a central cavity with a bushing inserted therein, in different types of dispensers. The cooperation between the first and second spindle elements200,300,800,900can be adjusted depending on the dimensions of the web material rolls and the dispensers. For instance, the distance between the first and second dispenser mounting portions210,310,810,910can be adjusted by configuring the assembling rod400,1000in one of the first and second configurations (or retracted and extended configurations) or by inserting either a portion or an entirety of the free end402,1002of the assembling rod400,1000in the assembling cavity510,1110defined by the assembling sleeve500,1100.

The steps of the method can be carried out in a reverse order to remove and replace the roll20of web material, for instance when the entirety of the web material21has been dispensed. The method firstly comprises removing the first and second dispenser mounting portions210,310,810,910from the first and second sides12,16of the dispenser10. The method then comprises disassembling the first and second spindle elements200,300,800,900and removing the second spindle element300,900from the central cavity26of the web material roll20. The method then comprises removing the first spindle element200,800from the bushing30. Optionally, the removal of the first spindle element200,800can at least partially break the wall40of the bushing30: the wall40can indeed be at least partially received in one of the recess274,874,875of the first spindle element200,800and abut against the substantially vertical rear face of the tapered head270,870.

The spindle assembly100,700according to the present disclosure (or spindle adaptor) thus allows replacing a conventional spindle (or mandrel) of dispensers with the “spindle assembly” or “spindle adaptor”, so as to allow receiving rolls provided with a bushing inserted therein.FIG. 21represents a possible embodiment of a conventional spindle11(or mandrel, or web material roll support) that would prevent a web material roll20having a central cavity26provided with a bushing30from being dispensed by the dispenser10. In the embodiment shown, the mandrel11comprises first and second dispenser mounting portions13,15mountable respectively to the first and second sides14,16of the dispenser10. The mandrel11further comprises a body17extending between the first and second dispenser mounting portions13,15and having a substantially constant cross-section that prevents the mandrel11from being engaged in the bushing30provided in the cavity26of the web material roll20.

The spindle assembly100,700thus allows dispensing different types of rolls of web material with a bushing inserted in the cavity of the roll in different types of dispensers. In other words, thanks to the spindle assembly100,700, the type of rolled material web dispensable by the dispenser10is not limited solely to the rolls configured to cooperate with the conventional spindle of the dispenser10.

For instance, the assembling rod400,1000could extend from the inner end304,904(opposed to the outer end302,902) of the second spindle element300,900and the assembling sleeve500,1100could be formed in the first spindle element200,800.

In another embodiment (not represented), the bushing-engaging member of the spindle assembly could be dimensioned to extend from the first extremity of the web material roll to the second extremity and would comprise first and second dispenser mounting portions to be mounted to the first and second sides12,16of the web material dispenser10. In other words, the bushing-engaging member could comprise a bushing-mounting portion extending between the first and second dispenser mounting portions. For instance, the second dispenser mounting portion of the bushing-engaging member would have an outer cross-section smaller than an inner cross-section of the bushing, for the second dispenser mounting portion to be introduced into the central cavity of the web material roll via the first extremity.

It could also be conceived a web material roll that would be shaped and dimensioned to be dispensed in a web material dispenser with a spindle assembly comprising only a bushing-engaging member with a first dispenser mounting portion. In other words, it could be conceived a web material roll that would be shaped and dimensioned to be mounted to the web material dispenser only by the first dispenser mounting portion of the bushing-engaging member. For instance, the bushing-engaging portion of the bushing-engaging member could be shaped and dimensioned to fully support the web material roll.

As can be appreciated, the spindle assembly described above advantageously allows insertion of paper rolls provided with bushings in conventional dispensers. Of course, numerous modifications could be made to the embodiments described above without departing from the scope of the present disclosure.
