The present disclosure relates to a dispenser for a continuous web of tissue, the dispenser comprising an outer casing being detachably or hingeably attached to a back portion. The dispenser comprises a compartment between the outer casing and the back portion for housing a first continuous web of tissue. The dispenser comprises a first opening for the first continuous web of tissue to exit the dispenser. The dispenser comprises a tear unit for separating the first continuous web of tissue into pieces upon moving the first continuous web of tissue over the tear unit.
Dispensers for dispensing a continuous web of tissue such as toilet paper dispensers are well known in the art. The dispensers may comprise a housing in which a roll of continuous web is placed. From the roll the web of tissue is drawn and dispensed through a dispenser opening. The web of tissue is usually distributed from the periphery of the roll. The dispenser opening is usually located at the bottom of the dispenser. The dispenser opening may comprise tear means for tearing the tissue into strips of suitable length.
Users having some form of disability, physical or otherwise, hindering them from using for instance their arms or shoulders to a full extent may have problems when tearing the tissue from a dispenser such as described above. The range of motion required may not be at all possible or may cause pain to the user.
If the paper in a dispenser having a dispensing opening located at the bottom of the dispenser is torn off inside the dispenser a user must reach into it in order to reach the end tab. Apart from being uncomfortable and/or difficult the user may scrape their hands or arms on the tear means.
There exists centre feed dispensers which allows a user to pull paper from the centre of a roll positioned in the dispenser. One example of a centre feed dispenser is shown in EP 1799083 A. The dispenser is equipped with a nozzle in order to reduce crumpling of the paper. This dispenser however does not address the issue of simplifying the dispensing of paper for a user having some form of disability as mentioned above.
There is thus a need for a dispenser that aims to solve the above mentioned problem.
The object of the present disclosure is to provide an inventive dispenser for a continuous web of tissue where the previously mentioned problems are avoided. This object is achieved by the features of the characterising portion of claim 1, wherein the first opening is positioned at a first distance L from the tear unit, the first distance L being arranged to fit a predetermined hand for allowing the predetermined hand to grip the first continuous web of tissue positioned partly or completely within the range of the first distance L. Here, “partly” means that tissue extends from the first opening to a point within the first distance and “completely” means that that tissue extends from the first opening to a point equal to or beyond the end point of the first distance, i.e the piece of tissue positioned outside the dispenser could have a length less than, equal to or longer than the first distance.
The present disclosure relates to a dispenser for a continuous web of tissue, the dispenser comprising an outer casing being detachably or hingeably attached to a back portion, the dispenser comprising a compartment between the outer casing and the back portion for housing a first continuous web of tissue. The dispenser comprises a first opening for the first continuous web of tissue to exit the dispenser. The dispenser comprises a tear unit for separating the first continuous web of tissue into pieces upon moving the first continuous web of tissue over the tear unit, wherein the first opening is positioned at a first distance L from the tear unit. The first distance L is arranged to fit a predetermined hand for allowing the predetermined hand to grip the first continuous web of tissue positioned partly or completely within the range of the first distance L.
A dispenser comprising an opening positioned at a distance from the tear unit enables a disabled user to grasp a leading edge of tissue with the entire hand (first grip) rather than pinching the tissue, then to pull out an adequate amount of tissue at an exceptionally low force, and then tearing the tissue by a movement which is more ergonomic than that for a “sheet-by-sheet” type centre feed dispenser, using only a limited load on the shoulder. Pinching the tissue is usually more difficult for users with impaired hand function rather than using a first grip. The user is able to fit their hand in the space created by that the opening is positioned at a distance from the tear unit. The first continuous web of tissue extends at least partly into the space created by that the first opening is positioned at a distance from the tear unit. The wrist may be kept essentially in a neutral position during the tearing of the first web of continuous web of tissue. This allows for a user to more easily grasp the first continuous web of tissue using the entire hand instead of having to grip the continuous web of tissue with the fingers. This feature simplifies operation of the dispenser for a person having reduced motor function in the hand. A further advantage with the dispenser is that it is possible to choose the amount of paper you want to dispense. In EP 1799083 A the paper is dispensed one sheet at a time making it more difficult to choose the amount of paper the user wish to have dispensed.
A predetermined hand is meant to refer to a hand of a user having some form of physical disability hindering them from using for instance their arms or shoulders to a full extent thereby making it more difficult for them to use a conventional dispenser. The user may be an adult or a child and a man or a woman. The first distance is thus sufficiently large in order for at least a child's hand to fit. The dispenser is of course usable by a user that does not have a physical disability.
The first opening may be arranged such that the force required to pull the first continuous web of tissue from the dispenser is less than 8 N. Preferably the force required to pull the first continuous web of tissue from the dispenser is less than 4 N, more preferably less than 2 N. Another advantage with the dispenser according to the present disclosure is that the force required to pull the first continuous web of tissue through the first opening from the dispenser is lower than for a normal dispenser for a centre feed roll of tissue. See test data below. This simplifies the use of the dispenser for a user that has reduced strength in their hands and/or arms. This is important as the motion for pulling the paper from the dispenser is not ergonomic. The force for pulling the paper from the dispenser is greatly reduced. The force for tearing the paper is mainly dependent on the tear strength of the paper. Therefore the motion for tearing the paper should be designed to be as ergonomical as possible in order to spare the hands, arms and shoulder of the user.
The first opening may be positioned in a front surface in an outer casing part which is separate from the outer casing. One advantage of having the first opening positioned in the first outer casing part of the dispenser separate from the outer casing is to reduce the noise that can arise when the first web of continuous tissue is pulled from the dispenser. Loud noises arising from a conventional centre feed dispenser during use may be perceived as embarrassing for a user. A further advantage may be that manufacturing and assembly may be made easier and less costly than by having an outer casing made in one piece. The outer casing may also comprise a first outer casing part and a second outer casing part which are separate from the outer casing, mainly to simplify the manufacturing. For example, it may be advantageous to mould transparent and opaque parts separately. It may also be difficult to mould the tear unit and the space above and behind the tear-off section in one step. They may be moulded separately with subsequent assembly by snap fits, ultrasonic welding, gluing or other methods.
The first opening may be positioned essentially centrally in the dispenser. This allows for the first continuous web of tissue to be fed from a centrally fed roll of tissue via the first opening. Other alternatives for the position of the first hole are of course conceivable. The first hole may be placed closer to one of the side edges of the dispenser in order to reduce the distance between the first continuous web of tissue and the user. The first opening may also be positioned closer to the bottom or the top of the dispenser depending on special requests from a user. Regardless of the position of the first opening, the first distance should be sufficiently large in order for a hand to fit the predetermined hand properly.
The first opening may be positioned for allowing the first continuous web of tissue to be fed from a centrally fed roll of tissue via the first opening.
The tear unit may be integrated in the outer casing. This enables for the dispenser to be equipped with tear units adapted for specific disabilities in cases where the dispenser is located in a specific place.
The tear unit may be a separate unit from the outer casing, which separate unit is attached to the outer casing. Having a tear unit that is separate from the outer casing allows the material of the tear unit to be made in a different and more durable material than the rest of the outer casing. Having a separate tear unit also reduces noise when using the dispenser. As an example, if the tear-off is fixed to the back portion the noise will be reduced compared to fixation on the outer casing. The tear unit may comprise teeth made of the same material as the tear unit. The teeth may also be made of a different material than the remaining tear unit such as for instance a fibre reinforced material.
The dispenser may comprise a first depression for allowing a user to grip the part of the first continuous web of tissue that extends out of the first opening. By having a first depression positioned in the vicinity of the first opening allows for a user to more easily grasp the first continuous web of tissue. The depression causes the first continuous web of tissue to be positioned a distance from the surface of the dispenser allowing a user to reach behind the first continuous web of tissue. This further enables a user to grip the first continuous web of tissue using the entire hand instead of having to grip the first continuous web of tissue with the fingers. This feature further simplifies operation of the dispenser for a person having reduced motor function in the hand. The first depression is thus positioned at least partly within the first distance.
The tear unit may comprise a first arm positioned such that the first continuous web of tissue can be moved in a direction essentially perpendicular to the feeding direction of the first continuous web of tissue in the first opening and torn apart by tearing means comprised in the first arm. The tissue may at least partly be moved in a rotational manner in a plane essentially perpendicular to the feeding direction in order to allow for the tissue to be torn by tear unit. The feeding direction is a direction essentially outwards from the dispenser. In the case where the tear unit comprises one arm the arm may be positioned in any direction such that the tear unit enables tearing of the continuous web of tissue.
The tear unit may comprise a first arm and a second arm positioned such that the first continuous web of tissue can be moved between the arms before being moved in a direction essentially perpendicular to the feeding direction of the first continuous web of tissue in the first opening and torn apart by tearing means comprised in the first arm.
The first continuous web may of course be torn apart by tearing means comprised in the second arm in the cases where this motion is easier for the user.
Each arm of the tear unit may be inwardly bent. Having bent arms simplifies the insertion of the first continuous web of tissue in the tearing means of the tear unit.
The first arm and the second arm may be positioned such that the second arm is essentially a mirror image of the first arm. Having the first and second arm positioned such that they are essentially each other's mirror image makes it possible to place the dispenser on either side of a toilet without having to adapt the dispenser for use for a particular side of a toilet.
The range of the first distance L may be between 50 mm and 250 mm, preferably between 100 mm and 150 mm.
The compartment of the dispenser comprises at least the first continuous web of tissue, but may house the first continuous web of tissue and a second continuous web of tissue. The dispenser according to the present disclosure may house a second continuous web of tissue in order for the dispenser to have to be refilled less often. This makes the dispenser suitable for placement in a high traffic restroom which may be found in for instance airports, fast food restaurants opened round the clock or toilets placed in other locations where a lot of people use the restroom over a greater portion of the day.
The dispenser comprises at least the first opening, but may comprise the first opening and a second opening. The first opening and the second opening are arranged such that the force required to pull the first continuous web of tissue or the second continuous web of tissue from either of the first opening or the second opening of the dispenser is less than 8 N. Preferably the force required to pull the first continuous web of tissue or the second continuous web of tissue from either of the first opening or the second opening of the dispenser is less than 4 N and more preferably the force required to pull the first continuous web of tissue or the second continuous web of tissue from either of the first opening or the second opening of the dispenser is less than 1.5 N. Having a dispenser with a first opening and a second opening allows for dispensing from either a first continuous web of tissue or a second continuous web of tissue. The choice of which continuous web of tissue to use can be made by for instance service personnel.
The dispenser may comprise a hatch arranged to be movable between a first end position and a second end position, where the hatch covers the first opening when the hatch is moved to the first end position and the hatch covers the second opening when the hatch is moved to the second end position. In order to hinder access to both continuous webs of tissue simultaneously a hatch may be present on the dispenser. The hatch may cover one of the openings while allowing dispensing of continuous web of tissue from the other opening. The hatch may be lockable by service personnel or may be held in place by a part of the first continuous web of tissue or a part of the second continuous web of tissue extending through the one of the first opening or second opening which is not covered.
The dispenser may comprise an elongated slot where the ends of the elongated slot comprise the first opening and the second opening.
In the cases where the dispenser houses a first continuous web of tissue and a second continuous web of tissue the dispenser may comprise multiple tear units or a single tear unit. The dispenser may also comprise multiple depressions or a single depression depending on the design of the dispenser.

In the drawings, like features have the same reference numbers.
a schematically shows a perspective view of a dispenser 1 according to a first aspect. The dispenser 1 comprises an outer casing 2 and a back portion 3, where the outer casing 2 is detachably or hingeably attached to the back portion 3 by means of first attachment means 4. The first attachment means 4 may be any attachment means suitable for attaching an outer casing to a back portion of a dispenser. The back portion 3 of the dispenser 1 may comprise second attachment means 5 (not shown) for attaching the dispenser 1 to a wall. The second attachment means 5 may be any attachment means suitable for attaching a back portion of a dispenser to a wall or another surface suitable for positioning a dispenser. The dispenser 1 may be lockable by locking means (not shown) such as a lock and key or another suitable means for only allowing access to the dispenser 1 for a janitor or other service personnel for refilling the dispenser 1.
The dispenser 1 further comprises a compartment 6 located between the outer casing 2 and the back portion 3. The compartment 6 is designed for housing a first continuous web of tissue 7. The first continuous web of tissue 7 may be a centre feed roll but other types of rolls such as peripheral feed rolls are possible. The outer casing 2 comprises a first opening 8 for the first continuous web of tissue 7 to exit the dispenser 1. The first opening 8 may be positioned in the centre of a front surface 9 of the outer casing 2 of the dispenser 1 but may be located anywhere on the outer casing 2 such that the first continuous web of tissue 7 may extend through the first opening 8. The outer casing 2 may comprise a first outer casing part 10 which is separate from the remaining outer casing 2. The outer casing 2 and the first outer casing part 10 are joined together during assembly of the dispenser 1. The outer casing may also comprise a first outer casing part 10 which is separate from remaining outer casing 2 or a second outer casing part (not shown).
The dispenser 1 further comprises a tear unit 11 comprising a first arm 12 located on the right side of the dispenser 1 and a second arm 13 located on the left side of the dispenser 1 for separating the first continuous web of tissue 7 into pieces upon moving the first continuous web of tissue 7 over any of the first arm 12 or the second arm 13 of the tear unit 11. The dispenser 1 may comprise either of the first arm 12 or the second arm 13 or both the first arm 12 and the second arm 13. The first arm 12 and the second arm 13 may be attached to the outer casing 2 of the dispenser 1 by means of ultrasonic bonding, mechanical attachments such as screws or welding. The tear unit 11 may alternatively form an integral part of the outer casing 2.
The first arm 12 comprises a first inner edge 14, a first outer edge 15, a first upper edge 16 and a first lower edge 17 opposite the first upper edge 16. The first arm 12 comprises first tear means 18 located along the first lower edge 17 of the first arm 12. The first tear means 18 may be teeth of various sizes, other kinds of serrated edges or any other suitable means for tearing or cutting a continuous web of tissue. The first tear means 18 may also be located along the other edges 14, 15, 16 of the first arm 12. The first arm 12 may also comprise additional tear means located along any edge 14, 15, 16, 17.
The second arm 13 comprises a second inner edge 19, a second outer edge 20, a second upper edge 21 and a second lower edge 22 opposite the second upper edge 21. The second arm 13 comprises second tear means 23 located along the second lower edge 22 of the second arm 13. The second tear means 23 may be teeth of various sizes, other kinds of serrated edges or any other suitable means for tearing or cutting a continuous web of tissue. The second tear means 23 may also be located along the other edges 19, 20, 21 of the second arm 13. The second arm 13 may also comprise additional tear means located along any edge 19, 20, 21, 22.
The first arm 12 and the second arm 13 are positioned such that they are essentially mirror images of each other. This enables the dispenser to be positioned on either side of a toilet without having to make modifications to the dispenser. It is of course possible to have a dispenser 1 having only the first arm 12.
b schematically shows a front view of the dispenser 1 according to
In the case of the dispenser 1 having both a first arm 12 and a second arm 13 the first outer edge 15 and the second outer edge 20 are placed at a distance from each other forming a gap 29.
c schematically shows a side view of the dispenser 1 according to
The dispenser 1 may comprise a transparent or translucent part making it possible to see how much of the first continuous web of tissue 7 that remains. This part may for instance be made up by a part or whole of the first depression 24. This part may also be located on one of the sides of the dispenser 1.
The first arm 12 and the second arm 13 may be curved as shown in

Test Method for Determining the Force Required to Pull the Paper from the Dispenser.
The purpose is to determine if existing paper qualities can function in new models of dispensers made for rolls. The method can also be used to test new paper qualities in existing dispenser models.
Principle
Existing or new paper qualities are tested in different dispenser models and prototypes made for rolls. The purpose is to get data on pull force, tail length and if tail is missing for three systems with different quality levels of paper. The three systems tested are SCA T2 Elevation dispensers (2 different models), Lotus SmartOne, and the dispenser according to the present disclosure, hereafter called GripRip.
Apparatus
Force Gauge, Mecmesin BFG 50 N, Id 103796 or Mecmesin BFG 200 N, Id 103800
Clamp, small (3×1 cm), ID 103797 or ID 103801
Clamp, big (12×1 cm), ID 103798
Calliper gage
Ruler
Sample Preparation
Start by placing the dispenser in the right position. The dispenser should be mounted according to the instructions in the package using all the accompanying screws.
Procedure
Note which series or likewise the dispenser belongs to (example Box 2000), which type of product it is made for (example T1), if the dispenser is a prototype and if so, which kind of prototype, the date when the test was performed, the signature of the person who performed the test, article number, numbers of ply, if the product is perforated or not, the diameter of a full roll (noted under diameter). Also measure the inner diameter of the cores in three different places in order to see if the core is symmetric.
Start by using Force Gauge, Mecmesin BFG 50 N, Id 103796 and the little clamp, if you receive a force higher than 45 N; change to Mecmesin BFG 200 N, Id 103800, if the paper breaks around the clamp; change to a big clamp. Do not forget to note which instrument and clamp which have been used. Hold the Force Gauge in the same angle as the paper comes out of the dispenser and place the display in front of you.
Measure both the pull force when dispensing the paper vertically out of the dispenser and the pull force needed to tear the paper off against the teeth. First attach the clamp (about 1 cm from the edge of the paper) and then pull the paper by moving the Gauge meter straight down with an even speed and a distance of one arm length, similar to the speed used when dispensing paper. The Gauge meter should register the largest force needed.
After the paper pull out force is measured, and if the dispenser style allows it, the force gauge is zeroed and the paper is torn off against the dispenser teeth (SCA T2 dispenser and GripRip dispenser). Highest measured force is written down.
For dispensers with the opening in the front, the paper is pulled with the force gauge straight out from the dispenser front to measure pull out force (Lotus SmartOne dispenser and GripRip dispenser).
The tail length is measured with a ruler after each dispensation and written down. The tail length is measured from the dispenser opening to the end of visible paper tail.
For the Grip Rip dispenser the same refills were used as in the T2 Elevation dispenser but with the core pulled out.
For the GripRip dispenser the roll is put on a paper board to be lifted a few centimeters to be in same level as dispensing hole for testing.
The test results for the pull force and the tail lengths for the different dispensers are shown in table 1.
As can be seen from the result the dispenser according to the present disclosure displays a lower pull force than the other dispensers tested. Also the tail length of the paper is much greater allowing a user to grasp the tail of the paper in order to pull the paper from the dispenser.
The distances mentioned in relation to
Although the above description mainly covers centre feed dispenser the present disclosure is not limited to only centre feed dispensers. Having a peripheral feed dispenser displaying the same advantages as mentioned above lie well within the scope of the present disclosure.
Reference signs mentioned in the claims should not be seen as limiting the extent of the matter protected by the claims, and their sole function is to make the claims easier to understand.
As will be realised, the dispenser described in the present disclosure is capable of modification in various obvious respects, all without departing from the scope of the appended claims. Accordingly, the drawings and the description thereto are to be regarded as illustrative in nature, and not restrictive. It may for instance be possible to combine the features of the different aspects in any way. This means for instance that a tear means from one aspect of the present disclosure may replace a tear means from another aspect of the present disclosure.
