DETAILED DESCRIPTION OF EXAMPLES OF THE INVENTION

[0088] FIG. 1 depicts an example of a dispenser 1 for dispensing web-shaped absorbent material from at least one centrefeed roll of web-shaped absorbent material. As outlined in the above, the web-shaped absorbent material may be any material suitable for cleaning and/or wiping purposes. For example, the web-shaped absorbent material may be a paper tissue or towel material or a non-woven tissue or towel material. Further, the web-shaped absorbent material is intended to be separated into individual portions or products before use. In some variants, the separation may be made at controlled locations along the web material, whereas in other variants, the separation may be made anywhere along the web-shaped absorbent material, as selected by the user, to receive a portion of the web-shaped absorbent material having a length suitable for the cleaning or wiping purpose. For example, the web-shaped absorbent material may be provided with perforation lines or other weakening lines facilitating the separation of the web material into individual products.

[0089] To accomplish the separation into individual portions or products, the dispenser 1 may be provided with suitable separation means.

[0090] The web-shaped material may typically be a disposable material, i.e. a material which is used only once or a few times and then discarded.

[0091] A roll of web-shaped absorbent material defines an imaginary roll axis X about which the web-shaped absorbent material is wound. A centrefeed roll of web-shaped absorbent material is a roll from which dispensing of web-shaped absorbent material is intended to take place from an absorbent material tail closest to the roll axis X. In some examples of centrefeed rolls, the initial absorbent material tail is located at or adjacent to the roll axis X. In other examples of centrefeed rolls, the roll is formed having an inner radius extending some distance from the roll axis X.

[0092] The centrefeed roll may be formed as a coreless roll. Alternatively, the centrefeed roll may be formed with a removable core, where the removable core is removed from the roll before dispensing of web-shaped material from the roll, e.g. a split-core.

[0093] As exemplified in FIG. 1, the dispenser 1 extends along a length direction L, a height direction H perpendicular to the length direction L, and a width direction W perpendicular to the length direction L and the height direction H. As such, the dispenser has a dispenser length Ld along the length direction, a dispenser height Hd along the height direction, and a dispenser width along the width direction Wd. The dispenser height Hd, length Ld, and width Wd may be adapted to enable the dispenser 1 to house the size of the roll or rolls to be accommodated in the dispenser. The length direction L, height direction H and width direction W refer to the dispenser 1. Although one possible orientation as illustrated in FIG. 1 is with the height direction H of the dispenser generally parallel to a vertical direction, and the length direction L of the dispenser generally parallel to a horizontal direction, other orientations of the dispenser in relation to a vertical and a horizontal direction are possible, as will be explained in the below.

[0094] Purely by way of example, as illustrated in FIG. 1, the dispenser 1 may be adapted for holding more than one roll of web-shaped absorbent material, such as the illustrated variant which is adapted for holding two rolls of web-shaped absorbent material.

[0095] For example, the dispenser length Ld may be greater than the dispenser height Hd. In the variant illustrated in FIGS. 1 to 3, the dispenser length Ld is at least 1.5 the dispenser height Hd, and may be at least 2 the dispenser height Hd.

[0096] The dispenser 1 comprises a housing 10 defining one or more roll compartments 100, 200 see FIG. 2, each roll compartment 100, 200 being dimensioned for holding one roll of web-shaped absorbent material during dispensing thereof, such that the roll axis of the one or more rolls is generally parallel with the width direction W of the dispenser.

[0097] As exemplified in FIGS. 1 to 3, for each of the one or more roll compartments 100, 200, the dispenser may define one dispensing opening 15, 25 arranged for dispensing of web material from the roll compartment 100, 200 to the outside of the dispenser 1 at least along the width direction W.

[0098] As exemplified in FIG. 1, the dispenser 1 may have a closed state, in which the dispenser 1 forms a closed exterior periphery apart from the one or more dispensing openings 15, 25, which communicate with the interior of the dispenser 1 to allow dispensing of web material from one or more rolls arranged in the dispenser 1.

[0099] As exemplified in FIG. 2, the dispenser 1 may have another, open state, in which the dispenser 1 is open to the exterior so as to allow introduction of at least one roll of web-shaped material into the dispenser 1.

[0100] Purely by way of example, as in the illustrated variant, the introduction of a roll of web-shaped material into the dispenser 1 may be made by introduction of the roll generally along the width direction W of the dispenser 1.

[0101] Purely by way of example, and as illustrated in FIG. 2, the dispenser 1 may be a dispenser for dispensing perforated web-shaped absorbent material, and may be provided with a dispensing element adapted to ensure that the web-shaped absorbent material is separated along the perforation lines when dispensed. In the illustrated variant, a dispensing element in the form of a nozzle 16, 26 is arranged for each roll compartment 100, 200. The nozzle 16, 26 may form part of the respective dispensing opening 15, 25. For example, the nozzle 16, 26 may form a conical path for the web-shaped material, which conical path is narrowing towards the dispensing opening 15, 25 so as to enable separation of the web material along the perforation lines by means of friction. As such, the dispenser 1 may provide for one-by-one product dispensing of individual products from the web-shaped material.

[0102] Purely by example, and as illustrated in FIGS. 1 to 3, the housing 10 may comprise a back wall 52 extending generally in the length direction L and in the height direction H, i.e. generally perpendicular to the width direction W. Further, purely by way of example, the housing 10 may comprise a first pair of opposing side walls 54 extending from the back wall 52 and generally in the width direction W and the height direction H. Also, the housing 10 may comprise a second pair of opposing side walls 56 extending from the back wall 52 and generally in the width direction W and in the length direction L.

[0103] For example, and as illustrated in FIGS. 1 to 3, the dispenser 1 may comprise a cover 40 arranged to the housing 10. The cover 40 may comprise the dispensing opening 15, 25 for each roll compartment 100, 200. Further, the cover 40 may comprise any dispensing elements such as a nozzle 16, 26 for each dispensing opening 15, 25.

[0104] For example, and as in FIGS. 1 to 3, the cover 40 may be hinged to the housing 10 by a hinge element 60. The hinge element 60 may be arranged to one of the side walls 54, 56 of the housing 10.

[0105] As such, in the closed position, as illustrated in FIG. 1, the cover 40 and the housing 10 form a closed exterior of the dispenser 10, apart from the dispensing openings 15, 25, through which dispensing of web-shaped material from a roll of web-shaped material when present in the roll compartment is allowed.

[0106] In the open position, as illustrated in FIG. 2, the dispenser 1 is open towards the one or more roll compartments 100, 200 such that a new roll may be inserted in the roll compartment 100, 200 by insertion of the roll generally along the width direction W of the dispenser 1.

[0107] The dispenser 1 may further comprise one or more windows 18, 28 enabling visual inspection of the content in the one or more roll compartments 100, 200. As such, the one or more windows 18, 28 may be formed by at least partly transparent material and may be arranged so as to enable visual inspection of at least a portion of a roll arranged in the roll compartment 100, 200. Purely by way of example, as illustrated in FIGS. 1 to 3, the windows 18, 28 may be arranged in the cover 40.

[0108] The cover 40 which is arranged to the housing 10 may, as in the illustrated example, form a front wall of the dispenser 1, which front wall extends essentially in the height and length directions of the dispenser 1. Further, the cover 40 may comprise cover side wall portions extending generally in the width direction W from the front wall, so as to meet with the side walls 54, 56 of the housing 10 when the dispenser 1 is in a closed state.

[0109] For example, and as in the dispenser 1 illustrated in FIGS. 1 to 3, the cover 40 may be configured to cover more than one roll compartment 100, 200, such as a first roll compartment 100 and a second roll compartment 200. In other alternatives, the dispenser 1 may comprise two or more cover portions, each cover portion covering one out of the roll compartments 100, 200 of the dispenser.

[0110] Purely as an example, the housing 10 and/or the cover 40 may comprise one or more locking members 70 for locking the dispenser 1 when in the closed state. The locking member(s) 70 may for example be lockable and openable with a key.

[0111] Optionally, the dispenser 1 may comprise a suspension arrangement adapted for suspending the dispenser 1 to a generally vertical structure, such as a wall.

[0112] Since, as will be further explained in the below, the dispenser 1 proposed herein provides for versatility regarding the orientation of the dispenser 1 in relation to a vertical axis, the suspension arrangement may be adapted for suspending the dispenser to a generally vertical structure with the height direction H of the dispenser 1 substantially extending along a vertical direction, and for alternatively suspending the dispenser to a generally vertical structure with the length direction L of the dispenser 1 substantially extending along a vertical direction. Such a suspension arrangement may for example be provided at the back wall 52 of the housing 10.

[0113] For example, such a suspension arrangement may comprise a number of hooks and/or holes on the back wall 52 of the housing, out of which some hooks and/or holes are adapted for use when suspending the dispenser 1 with the height direction H substantially extending along a vertical direction, and some hooks and/or holes are adapted for use when suspending the same dispenser 1 with the width direction W substantially extending along a vertical direction. Alternatively, the same hooks and/or holes may be used for the different orientations of the dispenser 1.

[0114] As outlined in the above summary section, to ensure the function of the dispenser 1 when oriented along different directions, it is desired that the one or more rolls 2 are adequately supported in the dispenser 1 and that the centre axis (-es) X of the one or more rolls 2 is/are correctly positioned in relation to the dispensing opening(s) 15, 25, regardless of orientation of the dispenser 1.

[0115] To this end, the dispenser 1 comprises the one or more roll compartments 100, 200.

[0116] With reference to FIG. 3, each roll compartment 100, 200 is dimensioned for holding one roll 2, 2 of web-shaped absorbent material during dispensing thereof, such that the roll axis X of each roll 2, 2 is essentially parallel to the width direction W.

[0117] Each roll compartment 100, 200 is delimited by at least three separate roll compartment surfaces 110, 120, 130; 210, 220, 230 arranged to face an outer periphery of the roll 2, 2 in direction perpendicular to the roll axis X. Each roll compartment 100, 200 defines a central width axis W1, W2 parallel to the width direction W, and a central height axis H1, H2 (see FIG. 4a) parallel to the height direction H and crossing the width axis W1, W2. Further as seen in a direction projection of the dispenser 1 in the width direction W, each roll compartment 100, 200 encompasses an imaginary circle with a radius R from the central width axis W1, W2.

[0118] In the following, reference will be made to FIGS. 4a to 4c depicting a direction projection of the dispenser 1 in the width direction W of one roll compartment such as the first roll compartment 100 of the dispenser illustrated in FIGS. 1 to 3. Thus, the description in the below is equally applicable to one or more roll compartments in a dispenser, such as to the second roll compartment 200 of the dispenser 1 illustrated in FIGS. 1 to 3.

[0119] As exemplified in FIGS. 4a to 4c, each roll compartment surface 110, 120, 130; comprises a roll contact surface portion 110c, 120c, 130c being arranged so as to contact the circumference of the imaginary circle. Thus, the roll contact surface portions 100c, 120c, 130c are all arc shaped surface portions following the periphery of the imaginary circle with the radius R about the centre width axis W1.

[0120] Each roll contact surface portion 110c, 120c, 130c thus extends over an arc of the circumference of the imaginary circle. Each roll contact surface portion is positioned on the circumference of the imaginary circle such that the arc of the circumference comprises at least a contact angle 1, 2, 3 as measured clockwise from the central height axis H1. Angle values greater than zero and angle values less than zero relate, as understood from FIG. 4a, to angles formed on two opposite sides of the central height axis H1, as seen in the plane spanned by the height and length directions H, L.

[0121] The contact angle 1 of the first roll contact surface portion 110c is located in the range from 5 to 85 degrees or alternatively located in the range from 5 to 85 degrees.

[0122] The contact angle 2 of the second roll contact surface portion 120c is located in the range from 95 to 175 degrees.

[0123] The contact angle 3 of the third roll contact surface portion 130c is located in the range from 95 to 175 degrees.

[0124] As such, the roll contact surface portions 110c, 120c, 130c are distributed around the circumference of the imaginary circle around the central width axis W1.

[0125] FIG. 5 schematically illustrates the imaginary circle of a roll compartment 100, with the contact radiuses 1, 2, 3 of the three contact surface portions 110c, 120c, 130c marked. As may be seen in FIG. 5, a normal to each contact surface portion 110c, 120c, 130c at the contact angle 1, 2, 3 will have a component in each one out of the length and height directions L, H of the dispenser 1. As outlined in the above, this implies that each contact surface portion 110c, 120c, 130c is efficient to support and maintain the roll in the compartment regardless of whether the dispenser is arranged with the height direction of the dispenser aligned with a vertical direction or with the length direction of the dispenser aligned with a vertical direction. As understood from FIG. 5, the normals to each contact surface portion 110c, 120c, 130c will meet at the central width axis W1. As such, the contact surface portions 110c, 120c, 130c are also efficient to centre the roll 2, i.e. to urge the roll 2 towards a position where the centre axis X of the roll coincides with the central width axis W1.

[0126] Optionally, one or two of the roll contact surface portions is arranged so as to contact the circumference of the imaginary circle over an arc of the circumference being less than a 5 degree arc of the circumference, such as less than a 2 degree arc of the circumference.

[0127] Optionally, each roll contact surface portion 110c, 120c, 130c is arranged so as to contact the circumference of the imaginary circle over an arc of the circumference being relatively small, such that less than a 5 degree arc of the circumference

[0128] As may be understood from e.g. FIG. 5, the minimum extension of each roll contact surface portion 100c, 120c, 130c would be a point of tangency as seen in the direction projection of the roll compartment along the width direction, the point of tangency thus being located at the respective contact angle 1, 2, 3. Thus, the roll contact surface portion would be arranged so as to contact the circumference of the imaginary circle essentially only at the respective contact angle 1, 2, 3.

[0129] For example, the contact angle 1 of the first roll contact surface portion 110c may be located in the range from 5 to 30 degrees or alternatively located in the range from 5 to 30 degrees. Purely as an example, in the illustrated dispenser 1, the contact angle 1 of the first roll contact surface portion is about 10 degrees.

[0130] For example, the contact angle 2 of the second roll contact surface portion 120c may be located in the range from 100 to 140 degrees, such as from 110 to 130 degrees. Purely as an example, in the illustrated dispenser 1, the contact angle 2 of the second roll contact surface portion is about 115 degrees.

[0131] For example, the contact angle 3 of the third roll contact surface portion 130c may be located in the range from 100 to 140 degrees, such as from 110 to 130 degrees. Purely as an example, in the illustrated dispenser 1, the contact angle 3 of the third roll contact surface portion is about 120 degrees.

[0132] The three roll contact surface portions 110c, 120c, 130c acting so as to support and centre the roll 2 such that the dispenser 1 may be arranged in numerous orientations, are per se sufficient to maintain the roll 2 in the desired position. As such, variants such as the illustrated dispenser 1, wherein no more than the three roll contact surface portions 110c, 120c, 130c are arranged so as to contact the circumference of the imaginary circle are feasible. This provides for efficient manufacturing of the dispenser 1 and may thus be advantageous.

[0133] The three roll contact surface portions 110c, 120c, 130c as distributed around the circumference of the imaginary circle will not only support the roll 2 from below regardless of the orientation of the dispenser 1, but also ensure that the central axis X of the roll 2 is centred adjacent or at the centre width axis W1.

[0134] As such, the spatial relationship between the central axis X of the roll 2 and the dispensing opening 15 see FIGS. 1 to 3 of the roll compartment 100 may be controlled regardless of the orientation of the dispenser 1, such that correct dispensing of web material from the centre of the roll 2 may be accomplished.

[0135] It may be preferred that, when seen in a direction projection of the roll compartment in the width direction W, no portion of the roll compartment extends radially inside of the imaginary radius R. As such, it may be ensured that the three roll contact surface portions are indeed efficient to centre the roll as intended.

[0136] However, it may be that in certain variants, an auxiliary element could be provided which, as seen in the direction projection in the width direction W, would indeed extend radially inside of the imaginary radius R. However, such an auxiliary element should be arranged so as not to affect the ability of the three roll contact surface portions to centre the roll in the roll compartment. Accordingly, any such auxiliary element could for example have a relatively limited extension as seen along the width direction W.

[0137] Optionally, and as exemplified in FIGS. 4a to 4c, one, two or three out of the roll compartment surfaces 110, 120, 130 may further comprise an extension surface portion 110e, 120e, 130e, arranged radially outside the circumference of the imaginary circle, as seen from the central width axis W1.

[0138] As such, the extension surface portion 110e, 120e, 130e may extend from a roll contact surface portion 110c, 120c, 130c, to an end of the roll compartment surface 110, 120, 130.

[0139] The extension surface portions 110e, 120e, 130e may optionally and as illustrated have an angular extension about the centre width axis W1 being greater than the angular extension of the corresponding contact surface portions 110c, 120c, 130c. The extension surface portions 110e, 120, 130e may for example have an angular extension at least 3 times, such as at least 5 times greater than the angular extension of the corresponding contact surface portions 110c, 120c, 130c.

[0140] For example, and as exemplified by the first roll compartment surface 110 of FIGS. 4a to 4c, the roll compartment surface 110 may comprise two extension surface portions 110e having a greater angular extension than the first roll contact surface portion 110c. In this case, the two extension surface portions 110e may be extending on each side of the roll contact surface portion 110c.

[0141] In another example, and as exemplified by the second roll compartment surface 120 and the third roll compartment surface 130 of FIG. 4a, the roll compartment surface 120, 130 may comprise one extension surface portion 120e, 130e having a greater angular extension than the second or third roll contact surface portion 120c, 130c, respectively. In this case, the extension surface portion 120e, 130e may be extending on one side of the roll contact surface portion 120c, 130c.

[0142] Thus, at the extension surface portions 110e, 120e, 130e, there is room for a roll 2 introduced in the roll compartment 100 to deviate at least slightly from the circumference of the imaginary circle. Although with the roll contact surface portions 110c, 120c, 130c as described in the above, the roll 2 is hindered from premature collapsing, there may nevertheless be some cases where the roll 2 collapses towards the end of the dispensing.

[0143] In this case, the roll 2 may fall downwards, and, depending on the direction of the dispenser, the web material of the roll may gather on one of the roll compartment surfaces 110, 120, 130, including the extension surface portions 110e, 120e, 130e.

[0144] The extension surface portions 110e, 120e, 130e may extend from the respective roll contact portion 110c, 120c, 130c and so as to extend at least over an extension angle 1, 2, 3 (see FIG. 4b). As such, each extension surface portion 110e, 120e, 130e is arranged outside the circumference of the imaginary circle over an arc of the circumference comprising at least the extension angle 1, 2, 3.

[0145] For example, and as exemplified in FIG. 4b, the extension angle 1 of the first extension surface 110e may be 0 degrees (the angle being 0 so not marked in FIG. 4b). This implies that the first extension surface 110e extends over an arc crossing the central height axis H1 of the roll compartment 100. As such, the first extension surface 110e may be efficient for supporting at least a collapsed roll 2 from below when the dispenser 1 is arranged with the height direction H of the dispenser 1 parallel to a vertical direction.

[0146] Alternatively or in addition, as illustrated in FIG. 4b, the extension angle 2 of the second extension surface 120e may be 90 degrees. This implies that the second extension surface 120e extends over an arc crossing the central length axis L1 of the roll compartment 100. As such, the second extension surface 120e may be efficient for supporting at least a collapsed roll 2 from below when the dispenser 1 is arranged with the length direction L of the dispenser parallel to a vertical direction, and with the second roll compartment surface 120 located below the third roll compartment surface 130.

[0147] Alternatively or in addition, as illustrated in FIG. 4b, the extension angle 3 of the third extension surface 130e may be 90 degrees. This implies that the third extension surface 130e extends over an arc crossing the central length axis L1 of the roll compartment 100. As such, the third extension surface 130e may be efficient for supporting at least a collapsed roll 2 from below when the dispenser 1 is arranged with the length direction L of the dispenser parallel to a vertical direction, and with the third roll compartment surface 130 located below the second roll compartment surface 120.

[0148] As such, the dispenser 1 may be adapted for arrangement in at least three different orientations: one with the height direction H of the dispenser 1 oriented along a vertical axis and the first roll compartment surface 110 located below the first and second roll compartment surfaces 120, 130, one with the length direction L of the dispenser 1 oriented along a vertical axis and the second roll compartment surface 120 located below the first and third roll compartment surfaces 110, 130, and one with the length direction L of the dispenser oriented along a vertical axis and the third roll compartment surface 130 located below the first and second roll compartment surfaces 110, 120.

[0149] Purely as an example, one or more of the first, second and third roll compartment surfaces 110, 120, 130 may be a curved surface following the arc of a circle having a radius of curvature being greater than the radius R of the imaginary circle. In this case, the first, second and/or third roll compartment surface 110, 120, 130 may suitably be arranged such that a portion of the first second and/or third roll compartment surface 110, 120, 130 contacts the circumference of the imaginary circle so as to form the first, second and/or third roll contact surface portion 110c, 120c, 130c as described in the above, whereas another portion of the first, second and/or third roll compartment surface 110, 120, 130 is located outside of the circumference of the imaginary circle, so as to form the first second and/or third extension surface portion 110e, 120e, 130e as described in the above. This implies that the starting points of the radii of curvature of the first, second and/or third roll compartment surfaces 110, 120, 130 would not meet in a common central point, and not coincide with the central width axis W1 of the roll compartment 100.

[0150] The first, second and/or third roll compartment surface 110, 120, 130 may, as intimated in the above, have an angular extension about the centre width axis W1. The angular extension of a roll compartment surface 110, 120, 130 thus comprises at least the angular extension of the roll contact surface portion 110c, 120c, 130c and any extension surface portions 110e, 120e, 130e.

[0151] For example, the first, second and/or third roll compartment surface 110, 120, 130 may have an angular extension about the centre width axis W1 being at least 30 degrees.

[0152] Optionally, and as shown in FIG. 4c, the first, second and/or third roll compartment surface 110, 120, 130 may have an angular extension 1, 2, 3 about the centre width axis W1 being at least 30 degrees.

[0153] Optionally, and as shown in FIG. 4c, the first, second and/or third roll compartment surface 110, 120, 130 may have an angular extension 1, 2, 3 about the centre width axis W1 being no more than 90 degrees.

[0154] For example, and as shown in FIG. 4c, the second and third roll compartment surface 120, 130 may each have an angular extension 2, 3 being less than the angular extension 1 of the first roll compartment surface 110.

[0155] In FIGS. 4a to 4c, a direction projection along the width axis W of the roll compartment 100 is illustrated.

[0156] Turning to the extension of the above-mentioned features along the width axis W, several variants are possible while still obtaining the advantages as set out in the above.

[0157] For example, the roll contact surface portions 110c, 120c, 130c of the first, second and third roll compartment surfaces 110, 120, 130 may be located in the same plane perpendicular to the width direction W. Thus, in at least one cross-section along the width direction W, the three roll contact surface portions 100c, 120c, 130c will be present and as defined in relation to the direction projection along the width direction. As such, the roll contact surface portions 110c, 120c, 130c will act to support and centre a roll 2 in the roll compartment 100 by contacting the roll 2 at least in a same plane perpendicular to the width direction W.

[0158] The dispenser may have a dispenser width Wd as seen in the width direction W (see FIGS. 1 and 2). As such, the roll contact surface portions

[0159] Optionally, the dispenser has a dispenser width Wd in the width direction W and the roll contact surface portions 110c, 120c, 130c may extend continuously over at least a portion of the dispenser width Wd. For example, the roll contact surface portions may extend continuously over at least 50% of the dispenser width.

[0160] As illustrated in FIGS. 4a to 4c in view of FIGS. 1 to 3, in an example variant, each roll compartment 100, 200 may comprise a first roll support member 11, 21 forming the first roll compartment surface 110, 210, a second roll support member 12, 22 forming the second roll compartment surface 120, 220, and a third roll support member 13, 23 forming the third roll compartment surface 130, 230.

[0161] Optionally, each of the first, second and third roll support members of the same roll compartment 100, 200 is an individual member. That being the case, two adjacent roll compartments 100, 200 such as the first roll compartment 100 and the second roll compartment 200 of the dispenser 1 in FIGS. 1 to 3, may share a single roll support member 13.

[0162] As such, the third roll compartment surface 130 of the first roll compartment 100 may be formed on one side of the roll support member 13, and the second roll compartment surface 220 of the second roll compartment 200 may be formed on another side of the roll support member 13, opposite the one side.

[0163] The roll support members 11, 12, 13, 21, 22, 23 may for example be formed as separate members from the remainder of the housing 10, which are attached to the housing 10 during manufacture. For example, one or more of the roll support members 11, 12, 13, 21, 22, 23 may be attached to the back wall 52 and/or to the first pair of side walls 54 and/or to the second pair of side walls 56.

[0164] In the illustrated example, the first roll support member 11 of the first roll compartment 100 arranged to one out of the second pair of side walls 56. The second roll support member 12 of the first roll compartment 100 is arranged to a first out of the first pair of side walls 54. The third roll support member 13 is arranged to the back wall 52 of the housing 10.

[0165] Further, the first roll support member 21 of the second roll compartment 100 is similarly arranged to one out of the second pair of side walls 56. The second roll support member 22 of the second roll compartment 100 is arranged to the back wall 52 of the housing 10, and is, in fact, constituted by a same member 13, 22 serving also as the third roll support member 13 of the first roll compartment 100. The third roll support member 23 of the second roll compartment 200 is arranged to one out of the second pair of side walls 56.

[0166] Many variants are possible for arranging the roll support members for example, a roll support member may, where suitable, be arranged both to a back wall 52 of the dispenser 1 and to a side wall 54, 56 of the dispenser 1.

[0167] Optionally, the roll support members 11, 12, 13, 21, 22, 23 may be removably attached to the remainder of the housing 10. As such, the roll support members may be removed from the remainder of the housing 10 and replaced e.g. by new roll support members. Thus, if one or more of the roll support members becomes worn or breaks, it may be replaced, thus increasing the lifetime of the dispenser.

[0168] In the above, it is described how the proposed roll compartment surfaces 110, 120, 130, 210, 220, 230 may provide for the required support and centering of a roll positioned in the roll compartment 100, 200 of a dispenser during dispensing, when the dispenser 1 is arranged in different orientations with respect to a vertical direction.

[0169] FIGS. 6a to 6b illustrate the dispenser 1 of FIGS. 1 to 3 as arranged three different orientations with respect to a vertical upward direction V. FIG. 6a illustrates an orientation where the dispenser height H is generally parallel to the vertical direction V, FIG. 6b illustrates a first orientation where the dispenser length L is generally parallel to the vertical direction V, and FIG. 6c illustrates a second orientation where the dispenser length L is generally parallel to the vertical direction V. Each orientation thus provides for different requirements when it comes to available surface e.g. on a vertical wall for suspending the dispenser 1, and for different requirements when it comes to the volume in the room necessary for allowing the opening of the cover 40 so as to allow introduction of rolls of material into the dispenser 1.

[0170] For completeness, it may be mentioned that also additional elements may be comprised in the dispenser e.g for hindering collapse of the roll 2, 2 during dispensing.

[0171] For example, and as illustrated in the dispenser of FIGS. 1 to 3, each roll compartment 100, 200 may comprise a central support bar 17, 27 arranged concentrically with the central width axis W1, W1 of the roll compartment 100, 200. Such a central support bar 17, 27 may facilitate positioning of a new roll in the roll compartment 100, 200. Further, the support bar 17, 27 may be effective to support at least a portion of the web-shaped material of the roll 2 in the case the roll collapses. When the roll compartment 100 comprises a central support bar 17, 27, this implies that the dispenser 1 is suitable for centrefeed rolls having an initial inner perimeter of a size sufficient to house the central support bar 17, 27.

[0172] In another example, and as illustrated in the dispenser of FIGS. 1 to 3, the dispenser 1 may comprise one or more roll side contact protrusions 19, 29 for each roll compartment 100, 200. Such roll side contact protrusions 19, 29 may protrude from the back wall 52 of the dispenser 1 and/or from a front wall opposing the back wall 52, such as in the illustrated dispenser 1, from the cover 3, towards the roll compartment 100, 200. As such, the roll side contact protrusions 19, 29 are intended to protrude in the width direction W of the dispenser 1, so as to contact or to penetrate an end surface perpendicular to the roll axis X, X of a roll 2, 2. As such, the roll side contact protrusions 19, 29 are intended to inhibit premature collapse and/or rotation of the roll 2, 2 inside the roll compartment 100, 200. The roll side contact protrusions 19, 29 may be arranged at a radial distance from the centre axis W1, W2 of the roll compartment 100, 200 less than the radius R of the imaginary circle mentioned in the above, i.e. less than the radius of a roll 2, 2 intended to be positioned in the roll compartment 100, 200.

[0173] The term direction projection along a direction as used throughout the above is to encompass a projection onto a plane perpendicular to the direction (i.e. the direction is a normal to the plane). For explaining the term, FIG. 7 illustrates a cylinder having a height extending along a direction a and a diameter extending along a direction b. The direction projection of the cylinder along the direction a is hence a circle. The direction projection of the cylinder along the direction b is instead a rectangle.

[0174] It is to be understood that the present invention is not limited to the variants described above and illustrated in the drawings; rather, the skilled person will recognize that many changes and modifications may be made within the scope of the appended claims.
