Description
- The present invention relates to a dispenser for web of absorbent paper, tissue or nonwoven material in the form of a roll according to the precharacterizing portion of claim 1.
- Some dispensers for web of absorbent paper, tissue or nonwoven material in the form of a roll are provided with a web feeding mechanism. The feeding mechanism is commonly operated by a user for feeding out a required amount of web.
- U.S. Pat. No. 4,406,421 discloses a paper towel dispenser wherein web from a roll is dispensed between a drive roller and an idle roller. A linear gear rack and an integral gear actuating lever rotate the drive roller. The actuating lever is manipulated a desired number of times by a user to feed out web through a dispensing outlet of the dispenser. The web is then stripped from the dispenser at a serrated edge at the dispensing outlet.
- US2004/0135028 discloses a dispenser for sheet material on a roll. The dispenser has a handle which drives a feeding mechanism. The feeding mechanism includes a drive roller and an idle roller which cooperate to form a pressure nip, through which sheet material is dispensed. A handle is actuated by a user to rotate the drive roller in order to feed out a predetermined amount of sheet from the dispenser.
- In another type of dispenser, a user grasps and pulls on a dispensing end of the web from the roll to feed out a desired amount of web from the dispenser. In this type of dispenser it may sometimes be difficult to locate a dispensing end of web to grasp. It is known to use a push button mechanism engaging directly with an axle of the roll and arranged to feed out a portion of the web. The bush button mechanism pivots about an axis parallel with the axle of the roll.
- An object of the present invention is to provide a dispenser for web of absorbent paper, tissue or nonwoven material from a roll, where the dispenser is of the type where a user pulls on the web to dispense web, in which dispenser grasping of a dispensing end of web is facilitated.
- According to an aspect of the invention, the object is achieved by a dispenser for web of absorbent paper, tissue or nonwoven material in the form of a roll having a centre axis. The dispenser comprises a housing with a first dispensing opening for the web and a drive roller extending along a longitudinal axis. The drive roller is arranged in the housing in, or at, the dispensing opening with the longitudinal axis being substantially parallel to the centre axis. The roll is arranged to abut the drive roller to be frictionally engaged with the drive roller. The dispenser further comprises a feeding mechanism for rotating the roll to feed the web in a direction from the roll towards the first dispensing opening. The dispenser is adapted for a user to grasp, and pull on, a dispensing end of the web to dispense a length of web from the roll. The feeding mechanism comprises a bar extending at least partially along the drive roller. The bar, at a first end, is pivotably attached to the housing to pivot about a pivot axis and, at a second end, is provided with a gear rack. The drive roller is at one end provided with a cog wheel. The gear rack and the cog wheel are engaged such that when the bar is pushed from a start position to rotate about the pivot axis, the drive roller and the roll are caused to rotate. The bar is biased towards the start position such that when pushing the bar to rotate about the pivot axis towards an end position and subsequently releasing the bar, the bar pivots back to the start position.
- Since the feeding mechanism is provided to feed web from the roll, a dispensing end which was not graspable inside the dispenser, after pushing the bar of the feeding mechanism once or more times, is made graspable at or outside the first dispensing opening. As a result, the above mentioned object is achieved.
- The housing of the dispenser may comprise two or more housing portions, and at least one housing portion may be opened for refilling the dispenser with a full roll. Web is dispensed from an outer periphery of the roll. The drive roller may be provided with a rubber or rubberlike outer surface portion to ensure a sure grip between the drive roller and the roll. The bar may be biased e.g. by a spring arranged between the bar and the housing. The spring may for example be a torsion spring, pressure spring or tension spring. A full travel of the bar of the feeding mechanism, from the start position to the end position, may cause a length of about 1-8 cm to be fed from the roll.
- According to example embodiments the pivot axis is substantially perpendicular to the centre axis of the roll. Thus, the pivot arm may pivot in a plane parallel to the roll and the drive roller.
- According to example embodiments the drive roller is provided with a one-way bearing between the cog wheel and the drive roller, the one-way bearing being arranged such that the drive roller is rotated when the bar is moved from the start position and the drive roller remains stationary when the bar returns back to the start position. In this manner it is not risked that the drive roller pulls the dispensing end of the web back into the housing of the dispenser, upon returning to the start position.
- According to example embodiments the bar is provided with a push surface to be pressed by a user when moving the bar from the start position towards the end position, and wherein the push surface may be arranged in a vicinity of the first dispensing opening. In this manner a position on the bar, where a user suitably presses the bar towards the end position, may be provided. Further the push surface may be provided in a position where a user will expect to find a dispensing end of the web, namely at the first dispensing opening.
- According to example embodiments the bar may be provided with a push surface to be pressed by a user when moving the bar from the start position towards the end position, and wherein the housing may comprise an outer dispensing opening arranged at a distance from the first dispensing opening and the push surface may be arranged in a vicinity of the outer dispensing opening. Again, a position on the bar, where a user suitably presses the bar towards the end position, may be provided and the push surface may be provided in a position where a user will expect to find a dispensing end of the web, namely at the outer dispensing opening. Depending on the distance between the first and the outer dispensing opening, the push surface may be provided in a vicinity of both the first and the outer dispensing openings. According to example embodiments the push surface may be arranged approximately at a middle portion of the bar.
- According to example embodiments the housing may comprises an engaging roller in, or at, the first dispensing opening, wherein an outer peripheral surface portion of the engaging roller may be frictionally engaged only with the dispensing end of the web. The engaging roller may thus be caused to rotate by the dispensing end of the web being pulled out through a dispensing passage formed between the drive roller and the engaging roller. The engaging roller may be provided with a rubber or rubberlike surface portion to ensure frictional engagement with the web.
- According to example embodiments the drive roller and the engaging roller may form a friction nip adapted to frictionally engage with the dispensing end of the web. The friction nip may be achieved by the web being frictionally engaged with both the drive roller and the engaging roller. This may be achieved by a non-linear dispensing passage. The friction nip may cause that a sheet from a dispensing end of the web, in particular when the web is a perforated web, to separate outside the friction nip. In case the sheet is separated from the dispensing end of the web such that the dispensing end is difficult to reach, e.g. between the drive roller and the engaging roller, the feeding mechanism may be utilized by a user to feed the dispensing end to become easily graspable.
- According to example embodiments the roll may be biased against the drive roller. In this manner a reliable frictional engagement between the drive roller and the roll may be ensured.
- According to example embodiments the dispenser may be a portable dispenser. In a portable dispenser, which may be relatively light, the feeding mechanism may be particularly useful. The portable dispenser may easily be displaced if a user has to tinker with the dispenser to reach a dispensing end. Since the bar of the feeding mechanism extends along the drive roller, the bar is easily pressed by a user. In particular if the bar is to be pressed in an essentially downward direction, the dispenser will not be displaced.
- Further features of, and advantages with, the present invention will become apparent when studying the appended claims and the following description. Those skilled in the art will realize that different features of the present invention may be combined to create embodiments other than those described in the following, without departing from the scope of the present invention, as defined by the appended claims.

FIG. 1 schematically illustrates a cross section of adispenser 2 for aroll 4 of absorbent paper, tissue or nonwoven material according to example embodiments. The absorbent paper, tissue or nonwoven material is provided in the form of a web on theroll 4. Thedispenser 2 is portable and is provided with ahandle 6 to facilitate carrying or suspending thedispenser 2. Thedispenser 2 comprises ahousing 8 with anupper housing portion 10 and alower housing portion 12, which are shown in a closed position. In the closed position theupper housing portion 10 extends partially around the roll 4 (at least when it is full with web). Thelower housing portion 12 may be adapted to be placed on a surface. Thehousing portions first hinge 14. Opposite to thefirst hinge 10 there is formed a first dispensing opening 16 for a dispensingend 18 of the web between the upper andlower housing portions lid 20 which is foldable about asecond hinge 22. One purpose of thelid 20 may be to protect thefirst dispensing opening 16. Thelid 20 is provided with an outer dispensing opening 24 for the dispensingend 18 of the web. - The
housing 8 is provided with aholder arrangement 26 for theroll 4. Theholder arrangement 26 comprises anarm 28 with aseat 30 for anaxle 32 about which theroll 4 rotates. Thearm 28 is pivotally connected with thehousing 8 at an end of thearm 28 opposite to theseat 30. Aspring 34 biases thearm 28 and theroll 4 towards thefirst dispensing opening 16. At an opposite end of the roll 4 (not shown inFIG. 1 ) theholder arrangement 26 is provided with a corresponding arm/spring system, a pivotable arm only or other devices for moving theaxle 32 towards the dispensingopening 16. A roll rotational, or centre, axis of theroll 4 coincides with theaxle 32. - The
dispenser 2 further comprises adrive roller 36 and an engagingroller 38 arranged in thehousing 8 in close proximity to thefirst dispensing opening 16. Between thedrive roller 36 and the engagingroller 38 there is defined a dispensing passage through which web from theroll 4 may be dispensed by a user. Therollers end 18 of the web from theroll 4 is in contact with bothrollers rollers roll 4, by means of thearm 28 and thespring 34, is biased against thedrive roller 36. Thedrive roller 36 is thus frictionally engaged with theroll 4. Accordingly, when a user grasps and pulls on the dispensingend 18 of the web, the rotation of thedrive roller 36 is transferred to theroll 4. Thus, the peripheral speed of thedrive roller 36 and theroll 4 is the same. - The
drive roller 36 may be attached to thelower housing portion 12 and the engagingroller 38 may be attached to theupper housing portion 10. Accordingly, when theupper housing portion 10 is opened, therollers end 18 of the web from a roll is easily placed in the dispensing passage between therollers first dispensing opening 16. - The
drive roller 36 and the engagingroller 38 may each be provided with sections of small diameters and sections with large diameters as indicated by the broken lines inFIG. 1 . Thedrive roller 36 and the engagingroller 38 are in this case arranged in relation to each other such that a small diameter longitudinal section of thedrive roller 36 is opposite to a large diameter longitudinal section of the engagingroller 38, and a large diameter longitudinal section of thedrive roller 36 is opposite to a small diameter longitudinal section of the engagingroller 38. As mentioned above the dispensing passage is defined between therollers rollers rollers rollers 36, 38 (i.e. a direction perpendicular to the view presented inFIG. 1 ). Due to this overlapping of therollers - In such an undulated dispensing passage, the dispensing
end 18 of the web is in contact with both thedrive roller 36 and the engagingroller 38. Thedrive roller 36 and the engagingroller 38 have an outer surface with a high coefficient of friction. Accordingly, as the web is dispensed, both thedrive roller 36 and the engagingroller 38 will be rotated by the web. Since the web is in contact with both thedrive roller 36 and the engagingroller 38 and due to the high coefficient of friction, the dispensing passage is a friction nip. - A
bar 40 of afeeding mechanism 42 for rotating thedrive roller 36 is arranged in a vicinity of the first andouter dispensing openings bar 40 is provided with apush surface 44 to be pressed by a user to cause thedrive roller 36 and theroll 4 to rotate. -
FIG. 2 illustrates afeeding mechanism 42 for adrive roller 36 of a dispenser according to example embodiments. A first dispensing opening 16 of the housing is illustrated by a broken line and an outer dispensing opening 24 of the housing is illustrated by a dash-dotted line. Thedrive roller 36 is rotatably suspended at both its ends inposts 46 of a housing of the dispenser. Thedrive roller 36 is substantially parallel to a not-shown roll of absorbent paper, tissue or nonwoven material. As described above, thedrive roller 36 is provided with sections of small diameters and sections with large diameters. The sections having a large diameter are arranged to abut, and frictionally engage, with the not-shown roll. - The
feeding mechanism 42 comprises abar 40 which at one end is pivotable about apivot axis 48.
