Definitions

  • the invention relates to a roll of band-shaped paper material, such as toilet paper and towel material, wound round a hollow, cylindrical core of a readily degradable material, such as cardboard, paper pulp, starch or wood pulp, or another recyclable material, wherein the roll comprises two ends, each being of a different design.
  • a readily degradable material such as cardboard, paper pulp, starch or wood pulp, or another recyclable material
  • the roll can be placed in a dispensing device adapted thereto in one orientation only.
  • This has the advantage that after the roll has been placed in the dispensing device, band-shaped paper material unwound from the roll will always be situated at the front side of that device relative to the user, i.e. spaced from a wall on which that dispensing device is typically mounted. In this manner, this unwound band-shaped paper material is optimally accessible to the user, and spacing the material from the wall promotes hygiene.
  • caps which are insertable into the roll core and which have journals of different outside diameters and extending from that roll core, as known from US-A-3, 438, 589.
  • the caps cooperate with guideways provided in the housing of the dispensing device, which guideways have a cross dimension adapted to the journals.
  • the journal of the larger diameter should always be inserted into the guideway of the larger cross dimension
  • the journal of the smaller diameter should always be inserted into the guideway of the smaller cross dimension.
  • the caps are manufactured from plastic and are thrown away together with the roll core after exhaustion of the wound-up paper.
  • US-A-2, 380, 644 demonstrates another possibility of rendering the ends of the roll of different design.
  • the dispensing device comprises rotatable roll supports engaging the role core from either side, one of the roll supports having at least one projection capable of engaging a groove provided in the roll core and the paper wound thereon.
  • the roll supports should be swivelled outside the dispensing device. If the roll is installed the other way round, the projection presses the roll supports apart so far that the roll supports cannot be swivelled back into the dispensing device again.
  • the object of the invention is to provide a roll of the type referred to in the opening paragraph, wherein the above- described drawbacks do not occur.
  • this object is realized in that located adjacent one of the ends of the roll is at least one rib extending from the inside surface of the hollow core in the hollow core space bounded thereby, while such a rib is absent at the other end of the roll.
  • the roll support may have the form of a stub shaft with a slot dimensioned according to a rib, to a relatively thin wing diametrically fitting in the roll core.
  • the roll be designed so that it can be placed in a dispensing device in one orientation only.
  • the material used can also be chosen so that the environment is burdened as little as possible, for instance by manufacturing the rib(s) from the same readily degradable material as the core of the roll or from another recylclable material.
  • the band-shaped paper material wound on the core need not be processed for the purpose of providing a rib in the hollow core.
  • the rib provided in the hollow core can have any desired shape. However, in accordance with a further embodiment of the invention, a rib extending radially in the hollow core is preferred. The desired result can then be reached in a compact manner with relatively little material.
  • the roll support on the side of the rib can consist of a relatively thin wing fitting diametrically in the roll core.
  • two ribs are provided in a diametrical plane of the core of the roll.
  • the wing or a similar member of the roll support can then engage the two ribs and thus optimally support and guide the roll during the rotation for the purpose of withdrawing wound-up, band-shaped paper material.
  • it can reach from the outside through the wall of the roll core and be secured on the outside surface of the roll core by means of lateral wings.
  • a rib is formed by, starting from an annular sleeve having a length smaller than that of the hollow core and an outside diameter greater than the inside diameter of the hollow core, pressing a part of the sleeve inwards while reducing the outside diameter thereof, the resulting sleeve having an outside diameter so that it can be slid into the core with a sliding fit or with friction, and can be secured in the core in that slid-in position, for instance through glueing.
  • a known roll can quickly and simply be changed, without orientation means, into a roll with advantageous positioning orientation.
  • Such a rib can be formed in a simple manner if, in accordance with a further embodiment of the invention, the inwardly pressed sleeve part has a V-shape, with the legs of the V-shape being pressed together facewise and thus fixed relative to each other, for instance through glueing.
  • the rib be manufactured from the same material as the roll core or from another recyclable material. Accordingly, for that reason, the sleeve part is preferably manufactured from the same material as the roll core, for instance a readily degradable material, such as cardboard, paper pulp, starch or wood pulp, or another recylcable material. This is possible without any problem, because the sleeve part has the same starting form as the roll core.
  • the one-sided provision of a rib gives a positioning orientation.
  • that positioning orientation is not always directly perceptible, more particularly so if the roll is held in such a manner that one cannot look into the core. Under certain conditions, this may be considered less desirable.
  • the cylindrical core or an element fixed therein or thereon extends some distance beyond the end of the roll.
  • Such a construction can be realized in a simple manner if the annular sleeve bearing the rib or ribs extends some distance beyond the hollow cylindrical core.
  • Such a construction has the further advantage that when a number of rolls are packed, the part projecting on one side of a roll can reach into the end of an adjacent roll that does not have a projecting part, so that an optimally dense packing can be realized.
  • a roll according to the invention should be combined with a holder adapted thereto.
  • a holder comprising a housing with roll-supporting means, as is for instance known from US-A-3 ,438, 589, it be provided that the roll-supporting means reach into the cylindrical core, wherein the roll-supporting means on the side where one or more ribs are located in the hollow cylindrical core consist of a wing fitting diametrically in that core, which wing is mounted for rotation relative to the housing and can come into striking contact with a rib.
  • the other roll support can consist of a well-known stub shaft engaging the hollow roll core with play, around which stub shaft the roll can rotate, which then, on account of the wing striking a rib, causes that wing to rotate as well.
  • the rotatably arranged wing comprises a brake mechanism of variable brake powei .
  • the roll can be prevented from spontaneously unrolling further in an uncontrolled manner and unintentionally during the withdrawal of paper through pulling at it.
  • the tearing of the paper band at the desired location typically a perforation, can be promoted in that an increasing brake power facilitates the start of the tearing.
  • the brake power builds up from a minimum to a maximum and, after the maximum has been reached, runs down again to the minimum, with the building up and/or running down of the brake force preferably taking place stepwise.
  • Such a brake mechanism can be realized in a relatively simple manner, if it consists of a springing plate which is rotatable together with the wing and provided with at least one recess, into which recess a projection connected to the housing can reach, and the plate can spring outwards so that it is rotatable if a projection does not reach into a recess, while for obtaining a supple running, it is preferred that each projection consist of a ball partly mounted in a part connected to the housing. To spare the bearing of the rotatable wing as much as possible, it is further preferred that the springing plate be provided with at least one pair of diametrically opposite recesses capable of cooperating with one pair of diametrically opposite projections.
  • the springing plate will bend outwards symmetrically and, accordingly, not tend to swivel in a plane through the axis of rotation, which prevents a moment load on the bearing.
  • the roll according to the invention will be specified with reference to an exemplary embodiment shown in the accompanying drawing, wherein:
  • Fig. 1 shows a roll with core in side elevation
  • Fig. 2 shows a section taken on the line II-II in Fig. 1
  • Figs. 3-5 each show a core with a rib of different design
  • Fig. 6 schematically shows, in cross section, a roll included in a holder
  • Fig. 7 shows a cross section taken on the line VII-VII in Fig. 6;
  • Fig. 8 shows a roll support with wing in elevation; and
  • Fig. 9 shows a cross section taken on the line IX-IX in Fig. 8.
  • the roll 1 shown in Figs. 1 and 2 comprises a hollow cylindrical core 2 manufactured from a readily degradable material, such as cardboard, paper pulp, starch or wood pulp, or another recyclable material.
  • a long strip of band-shaped paper material is wound into a cylinder 3.
  • an annular sleeve part 4 is inserted and fixed therein.
  • This sleeve part 4 is preferably likewise manufactured from a readily degradable material, such as cardboard, paper pulp, starch or wood pulp, or another recyclable material.
  • the sleeve part 4 projects from the core 2 through a short distance, so that it is directly clear on which side of the core 2 the sleeve part 4 has been provided.
  • the sleeve part 4 comprises two inwardly extending ribs 5 which, starting from a sleeve part of larger diameter than sleeve part 4, are formed by pressing, at two diametrically opposite areas, parts of the circumference of that greater sleeve part inwards in the form of a V, until the legs of the V-form abut against each other, to form two radial ribs 5, as shown in Fig. 1.
  • Figs. 3-5 show a number of other structural variants for forming ribs.
  • a strip-shaped part is started from whose central part is pressed inwards in the form of a V, until the legs of the V-form abut against each other.
  • the thus formed rib 6 is passed through a slot provided in the core 7, after which the remaining flaps 8 are fastened to the outside surface of the core 7.
  • a sleeve part 9 is provided in the core 10, again in the manner of Fig. 1.
  • the legs of the V-form are not pressed against each other, so that these two ribs 11 form a V-shaped projection.
  • Fig. 3 a strip-shaped part is started from whose central part is pressed inwards in the form of a V, until the legs of the V-form abut against each other.
  • the thus formed rib 6 is passed through a slot provided in the core 7, after which the remaining flaps 8 are fastened to the outside surface of the core 7.
  • a sleeve part 12 is fitted in the core 13, which sleeve part has a rib 14 having the shape of a trapezoidal projection. It is observed that the sleeve parts 9 and 12, like the sleeve part 4, for that matter, need not extend beyond the core, but may also be entirely included therein. This last is shown in Fig. 6, where the outer end of the sleeve part 15 coincides with the outer end of the core 16 and the end face of the band-shaped paper material 17 wound on the core.
  • the sleeve part 15 is provided, in the manner of Fig. 1, with two diametrically opposite ribs 18.
  • the thus designed roll 19 is included in a holder 20 comprising sidewalls 21 and a rear wall 22.
  • the roll support 23 has the shape of a stub shaft reaching with play into the core 16.
  • the roll support 23 is mounted on an inner flange 25 which, via a shaft 26 bearing- mounted in the sidewall 21, is connected to an outer flange 27.
  • the roll support 24 has the shape of a wing, which reaches into the core 16 with play and can strike the ribs 18, as may appear most clearly from Fig. 7, wherein the walls of the housing 20 are left out.

  • the roll support 23 may also have many embodiments other than a wing.
  • that roll support may be constructed so as to be stub shaft-shaped, in the manner of roll support 23, with recesses being provided in that stub shaft, into which recesses the ribs 18 can reach. Any other shape between this modified stub shaft-shape and the wing is likewise possible.
  • the ribs 18 will drive the wing-shaped roll support 24 in rotation.
  • This drive can be utilized in an advantageous manner to provide a brake possibility which prevents the roll 19 from unrolling in an uncontrolled manner further than is desired when the free end of the paper band is pulled at.
  • This possibility is shown in Figs. 8 and 9, showing a wing-shaped roll support 28, albeit in changed form.
  • the wing-shaped roll support 28 is of a slightly Z-shaped design, causing the wing ends to strike the ribs in the core of the roll face-shaped.
  • the roll support 28 is fitted on an inner flange 29 which, via a shaft 31 bearing- mounted in the housing wall 30, is connected to a springing plate 32 acting as outer flange.
  • a springing plate 32 acting as outer flange.
  • the balls 34 have a diameter such that they fit in the recesses 33, as is shown in Fig. 9.
  • This slipping through, as it were, and the counterforce subsequently generated again through braking, can conveniently be utilized for introducing the tearing of the paper band, at the perforations that are typically present therefor, whereupon the further tearing takes place without undesired and uncontrolled unrolling of the roll of band-shaped paper.
  • a brake mechanism to be incorporated into a roll support can be of a construction other than shown in Figs. 8 and 9.
