Description

The invention relates to an easy-to-use, maintenance-free paper dispenser device for the uncomplicated and reliable provision of a moistened paper web, preferably toilet paper web, with a container for receiving a liquid, in particular a cleaning liquid, with an opening on the top which is delimited by the edges of the rear wall and the front wall, which for coupling to a receiving device arranged below the container for receiving a paper arrangement, preferably a paper roll with the wound paper web or a stack of paper with the stacked paper web, at least two moistening rollers rotatably arranged in the container, a rotatable pressure roller which is used to press the paper web against the moistening rollers suitable is. the lower circumferential surface of the pressure roller is spaced from the upper circumferential surface of the moistening rollers by a predetermined amount for moistening the paper web by the moistening rollers while the latter is being passed through.

In the EP 0 219 981 A paper dispenser device is disclosed in which a moistening roller is rotatably mounted in a container, against the circumferential surface of which a pressure roller rests in a moistening position, in the moistening position through the gap delimited by the circumferential surface of the moistening roller, which is partially located in a liquid, and the circumferential surface of the pressure roller an additional deflection roller deflected paper web of the paper roll is passed through. In the moistening position, the pressure roller presses the paper web against the fluidized circumferential surface of the moistening roller, so that the paper web is wetted by the moistened circumferential surface of the moistening roller facing the pressure roller. It turns out, however, that the entire surface of the paper web is wetted with the liquid, so that the paper web is able to tear either already in the gap or at the latest after leaving the gap as a result of the greatly reduced tear resistance caused by the waterlogging of the same, so that the conventional paper dispenser device is completely unable to Moistening the paper web is suitable.

In a normal position, the pressure roller is held above the circumferential surface of the dampening roller facing the pressure roller, so that there is no flat contact of the paper web with the circumferential surface of the dampening roller. In the normal position, the paper web can be pulled off the paper roll and a part can be separated from it via a tear-off edge.

From the EP 1 107 685 A1 a paper dispenser device for providing a moistened paper web is known, with a container for receiving a cleaning liquid, with an upper-side opening which is delimited by the edges of the rear wall and the front wall, which is for coupling to a receiving device arranged below the container for receiving a paper roll which a paper web can be wound up, is suitable, three moistening rollers rotatably arranged in the container and a rotatable pressure roller, which is suitable for pressing the paper web against the moistening rollers by means of a lever construction, the lower circumferential surface of the pressure roller from the upper circumferential surface of the moistening rollers with a predetermined Distance for moistening the paper web while passing the same is spaced.

Another device is from the WO 92/08403 A1 known, in which recesses are provided in the moistening rollers.

It turns out that some conventional paper dispenser devices are only used to provide the unmoistened paper web, but this requires a further disadvantage of the complicated structure of the deflection roller, the pressure roller, and the moistening roller. Accordingly, the conventional paper dispenser device is completely unsuitable for everyday use for providing the moistened paper web.

The conventional paper dispenser devices known in the prior art not only have the disadvantage of premature tearing of the moistened paper web, but also make the same significantly more difficult to handle, even making them impossible, because the interaction of the roller mimicry may require a linkage which is costly and costly to maintain is time consuming for the user.

The maintenance of the roller mimic with the linkage of the conventional paper dispenser device also requires a high degree of skill from the user, especially since guiding the paper web around the circumferential surfaces of the at least three rollers requires a high degree of skill.

The elimination of the paper malfunction not only requires a degree of skill on the part of the user, but is not sufficient for a z. B. toilet paper dispenser to make demands on everyday use, since the conventional toilet paper dispenser is set up at locations that are completely inaccessible to the technical assistance of another person in the event of a paper jam or paper tear within the same.

The hygiene and disinfection of the user's hands are becoming increasingly important, not only in the sanitary sector, but also in the industrial and hospital sectors.

A paper dispenser device is therefore required which makes it possible to dispense paper moistened with cleaning fluid in a simple, fast, uncomplicated and reliable manner.

The paper dispenser device to be provided should be low-maintenance, if not maintenance-free, in order to make it suitable for every user regardless of his or her skill level.

The paper dispenser device should also be easy to attach or set up at any location, so that the paper dispenser device is suitable for use in private households, in industrial, craft areas, as well as in areas that require compliance with special hygienic requirements, such as in hospitals, laboratories, Animal husbandry.

Usually damp cleaning after using the toilet is a clean and pleasant thing. However, when using conventional wet wipes, there are clear problems with the drying up and disposal of the wipes, so that high operating costs are incurred in the management of such toilets.

In addition, there is a risk of pipe and sewer cleaning, as the wet wipes have a high consistency and tear resistance and their composition differs significantly from conventional toilet paper, which does not lead to clogging of pipes.

There is therefore a need for a paper dispenser device which enables both the high demands placed on the hygiene and care of the user and the advantages of wet cleaning at the same time, without showing the disadvantages of wet toilet wipes.

In addition, the paper dispenser device to be provided should be simple in structure and easy to handle for the user.

Likewise, the paper dispenser device to be provided should avoid a jam of the paper web that occurs in comparison to the conventional paper dispenser device and enable the user of the paper dispenser device to insert a paper roll without requiring a high level of skill.

In addition, the paper web offered by the paper dispenser device should be a conventional toilet paper, which can be easily transported in the sewer system and in pipelines and does not tend to become clogged.

Likewise, the paper dispenser device should use conventional toilet paper in order to keep the operating costs of the paper dispenser device low, for example in industrial, craft and hotel businesses.

Likewise, the operating costs should not be unnecessarily increased by paper jams and increased expenditure on the maintenance of the paper dispenser device.

In addition, the paper dispenser device should offer the user a high level of hygiene without the user running the risk of coming into contact with parts thereof with his soiled or contaminated hands.

In addition, the paper dispenser device should be easy to set up or fasten.

Furthermore, the paper dispenser device is intended to moisten all types of paper webs, e.g. B. toilet paper, cleaning paper, household towels, can be used in workshops and businesses, as well as being widely used in hotels.

In addition, the paper dispenser device should reliably provide sufficient moistening of all types of paper web arrangements, such as rolled paper webs or stacked paper webs.

Furthermore, the paper dispenser device should offer permanently tear-resistant moistened paper for hand cleaning or disinfection in hospitals, kindergartens, etc., in which high demands are placed on hand hygiene in order to avoid hospitalism.

Finally, a paper dispenser device is also to be provided which makes it possible to dispense dry paper as well as moistened, sufficiently tear-resistant paper due to its simple operation.

The object is achieved by providing a paper dispenser device with the features according to the main claim. The subclaims relate to preferred configurations and further developments of the invention.

An additional object of the invention relates to the easy-to-use, maintenance-free cleaning paper dispenser device.

Another object of the invention relates to a paper web with a striped pattern with four stripes which run parallel to the central longitudinal axis of the paper web, are equally spaced from one another, and each strip has alternating moistened and non-moistened longitudinal sections.

The description also explains an easy-to-use, maintenance-free paper dispenser device for the uncomplicated and reliable provision of moistened and non-moistened paper web with a container for receiving a liquid, in particular a cleaning liquid, with an opening on the top that is delimited by the edges of the rear wall and the front wall, and one below of the container arranged receiving device for receiving a paper arrangement, in particular a paper roll having a wound paper web or a paper stack having the stacked paper web and
a pivoting device which is suitable for pressing the paper web against the moistening rollers in a moistening position,
which is characterized in that the pivoting device is adjustable from a stable normal position into an unstable (automatically resettable in normal position) moistening position and comprises a pressure roller rotatably mounted in the pivoting device, which is held at a distance from the moistening rollers in the normal position,
at least two moistening rollers are rotatably arranged in the container,
each moistening roller is retracted with the formation of at least one recess in its outer area,
in a normal position, the lower circumferential surface of the pressure roller is located above a straight line connecting the upper circumferential surface of the moistening rollers and the edge of the rear wall of the container, and
in a moistening position, the paper web can be pressed against the moistening rollers by means of the pivoting device.

The paper dispenser device according to the invention comprises a container with an opening at the top which is also delimited by the edges of the rear and the front wall. The container can hold the liquid, such as cleaning liquid. Any cleaning fluid that is suitable for hand or machine cleaning or other surface cleaning is suitable.

In the context of the invention, cleaning liquid is also understood to mean a disinfecting and / or dirt-removing liquid. The opening of the container can be closed by means of a lid.

A shaft to which the moistening rollers are permanently attached is rotatably mounted at its ends on brackets on the opposite side walls. Breakthroughs, U-shaped or V-shaped milled recesses running from the opening in the direction of the container bottom, or V-shaped or U-shaped strips formed on the inner sides of the side walls are suitable as holders.

The shaft of the moistening roller can be secured against uncontrolled removal by means of conventional locking pins or the like; In this embodiment, the moistening rollers with their shaft can be easily removed for cleaning after the securing pins have been removed.

Likewise, in another embodiment of the paper dispenser device according to the invention, the shaft can have two shaft parts which can be telescoped into one another against a spring force and the ends of which are resiliently held outwardly towards the ends by means of the spring force; Due to the resilient connection of the shaft parts, their free ends can be inserted into the perforations pre-punched in the side walls are introduced to provide the rotatability of the shaft.

Preferably, at least two moistening rollers are rotatably mounted on their common shaft in the lower region of the container. In the context of the invention, a moistening roller is also understood to mean a circular disc, the disc thickness or thickness of which is many times smaller than the width of the paper web. The slice thickness corresponds to such an extent that the moistening rollers can provide narrow moistening strips on the paper web. The ratio of the paper web width and to the width of the disc or to the dampening roll width can be 40 to 4, preferably 20 to 5, even more preferably 20, 12, 5 or 10. The ratio of the paper web width and to the width of a strip of the paper web can be 40 to 4, preferably 20 to 5, even more preferably 20, 12.5 or 10. In the context of the invention, the circumferential surface of the moistening roller can also be understood to mean the outside of the moistening roller configured as a circular disk.

The moistening rollers can also be permanently connected to one another and rotatably connected to a shaft coupled to holders of the container. In a special embodiment of the paper dispenser device according to the invention, four moistening rollers, preferably equally spaced apart, are firmly connected to the shaft rotatably mounted in the holders of the container.

The moistening rollers are arranged at a corresponding predetermined distance from the underside of the container, so that when the container is filled with the liquid, at least as a result of the rotation of the moistening rollers, their circumferential surfaces are wetted with the liquid and, as a result of their rotation, the wetted circumferential surfaces transfer the liquid to the, the paper web touching the upper surfaces of the dampening rollers. The moistening rollers can have a common axis of rotation with an identical radius or z. B. be designed in such a way that the distances between the upper circumferential surfaces facing the opening and the lower circumferential surface of the pressure roller coincide.

Each moistening roller is drawn in with the formation of at least one recess in its outer area. From a side view, the recess can be configured like a segment of a circle, a sector of a circle or an angular shape. The moistening rollers preferably have matching recesses for the representation of uniform stripe patterns.

The recess has the effect that in the moistening position the circumferential surface of the recess does not come into contact with the paper web, as long as the axis of rotation of the pressure roller always maintains a constant distance from the axis of rotation of the moistening rollers during its rotation. By pulling the paper web out of the container, the paper web is spaced from the recess in the region of the latter, so that a striped pattern appears the paper web is produced, the number of strips of which corresponds to the number of moistening rollers in the container and each strip comprises alternately occurring moistened and non-moistened longitudinal sections. The length z. B. of the dry or non-moistened longitudinal section corresponds to the length of the circumferential surface of the extension extending around the axis of rotation or shaft. The axes of rotation of the pressure roller, the dampening rollers and the paper rollers can be aligned with one another in such a way that they can be connected by means of a straight line or are arranged in a plane formed by the axes of rotation of the printing roller, the dampening rollers and the paper rollers. In the context of the invention, the circumferential surface of the printing roller can also be understood as the outside of the cylinder-shaped printing roller.

In the context of the invention, a pressure roller can also be understood to mean at least one sliding shoe which, with its lower support side facing the moistening rollers, attaches or presses the paper web against the circumferential surfaces of the moistening rollers. The width of the contact side of the sliding shoe can correspond to the width of the paper web or that of a moistening roller. The number of sliding shoes can correspond to the number of moistening rollers. The sliding shoes can be kept at a predetermined distance from the humidifying rollers.

The pressure roller can also be designed as a sliding shoe, for. B. which is rigidly connected to a rail, the ends of which are held in brackets on the inside of the side walls of the container. With their support side facing the moistening rollers, which can correspond to the lower circumferential surface of the pressure roller in their function of pressing the paper web against the moistening rollers, the paper web is placed against the upper circumferential surfaces of the moistening rollers to wet the paper web.

It is also possible that four sliding shoes are rigidly connected to the rail, facing four moistening rollers and are set against the paper web 4 in such a way that the paper web touches the upper circumferential surfaces of the moistening rollers in order to use the same. The advantage is shown that the circumferential surfaces of the recesses of the moistening rollers do not come into contact with the paper web, so that the paper web according to the invention is provided with its characteristic striped pattern with dry and moist longitudinal sections without the risk of paper tearing. Due to their own weight and / or by means of a spring force acting on the sliding shoes, the slide shoes can press the paper web against the moistening rollers with force applied.

The stripe pattern with, preferably equally spaced from one another, stripes with alternately occurring moistened and non-moistened longitudinal sections does not impair the tear resistance of the paper web in a very special way, even though the paper web is in this way is soaked or moistened with liquid that the paper web is completely sufficient for cleaning surfaces of all kinds.

It even turns out that the moistened paper web is even suitable for cleaning large surfaces, for example machines and parts thereof, without the paper web tearing as a result of the wetting according to the invention.

In addition, due to the moistening of the paper web by means of this stripe pattern, the dreaded peeling-off of the paper webs that have been moistened in the conventional way does not occur, so that, for example, when using a three-ply paper web, the three layers remain permanently connected to one another and their layers are easy to clean even with intensive flexing movements of the paper web for cleaning remain bonded to layers.

In a particular embodiment of the paper dispenser device according to the invention, at least four moistening rollers are arranged in the container, each of which is retracted, for example, with the formation of three recesses. The recesses of each moistening roller are advantageously equally spaced from one another. The moistening rollers with their recesses are preferably arranged with respect to one another in such a way that the recesses of two adjacent moistening rollers are spaced so that the recess of one moistening roller is adjacent to that portion of the moistening roller without a recess.

In a further embodiment of the paper dispenser device according to the invention, one or more circumferential surfaces of the moistening rollers are smooth or knurled, such as roughened or structured, in order to increase the wetting with liquid. It is also advantageous if only part of the circumferential surface of a moistening roller is curled, such as is roughened or structured; such a part of the circumferential surface of the moistening roller is that which is arranged between two recesses of the same moistening roller.

In addition, one or more circumferential surfaces of the moistening rollers can be coated with a layer which is liquid-attracting, e.g. B. has a special adhesion to liquids in order to increase their wetting with liquid. It is also preferable if only part of the circumferential surface of a moistening roller is provided with the layer; as such a part of the circumferential surface of the moistening roller, that which is arranged between two recesses of the same moistening roller is particularly suitable.

A chemical coating is preferred as the layer. In addition, a hydrophilic layer can be used that has a pronounced interaction with the liquid, e.g. B. a surfactant, e.g. B. surfactants, containing liquid. Also can one or more circumferential surfaces can be provided with a felt and / or fabric layer as an absorbent layer, that part of the circumferential surface of the moistening roller which is arranged between two recesses of the same moistening roller is particularly suitable.

In addition, that part of the circumferential surface of the moistening roller running around the axis of rotation, which is delimited by the recess ends for providing the recess, can be coated with a lipophilic, such as water-repellent, layer, e.g. B. coating, be provided in order to reduce the wetting of the recess with the liquid noticeably.

Due to the gap between the recesses of adjacent moistening rollers, such a striped pattern with, preferably equally spaced apart, strips with alternating moistened and non-moistened longitudinal sections is provided, the moistened longitudinal section of one strip being adjacent to the non-moistened longitudinal section of the opposite strip .

This specially designed strip pattern according to the invention with alternating but shifted moistening sections of the strips maintains exceptional tear resistance and insufficient ply detachment even with intensive flexing and folding movements of the paper web moistened with liquid, as occurs during cleaning regardless of the type of surface to be cleaned.

This so-called stripe pattern with alternating but mutually shifted moistening sections of the stripes also prevents the unwanted lateral tearing of the paper web when the paper web is pulled out of the paper dispenser device according to the invention very quickly, a temporal circumstance that often occurs as a result of routine work, so that the paper dispenser device according to the invention in particular in companies that pay attention to special hygiene regulations, such as hospitals, old people's homes, kindergartens, etc.

Since the paper dispenser device according to the invention is also characterized by easy handling due to the lack of maintenance costs and simple installation, the paper dispenser device according to the invention is also suitable for use in private households and guest accommodation, such as hotels, in sanitary areas, kitchens, etc.

The moistening rollers are advantageously arranged in the container with their axis of rotation such that the upper circumferential surfaces of the moistening rollers z. B. are aligned at the level of the edge of the front wall and / or the edge of the rear wall. The edges are partially circular in cross-section in order to avoid superficial damage to the paper web when it slides over the edges.

The paper web can be of a z. B. under the container or below the container arranged paper roll or stack of paper peeled off and over the upper edge of the Rear wall and guided over the circumferential surface of the moistening rollers in the direction of the edge of the front wall of the container are pulled out of this. In the particularly advantageous embodiment of the paper dispenser according to the invention, the pressure roller is spaced from the moistening rollers so far that the circumferential surface of the pressure roller facing the moistening rollers forms a gap with the upper circumferential surfaces of the moistening rollers; the gap bridging the opposing circumferential surfaces preferably remains unchanged. It is sufficient that the gap corresponds approximately to the layer thickness of the paper web or is slightly less than the layer thickness of the paper web.

In the context of the invention, the layer thickness is also understood to mean the distance between the upper side of the paper web and the lower side of the same in the unloaded or in the loaded, as well as force-applied, state.

The approximate correspondence of the gap with the layer thickness of the paper web is already sufficient, because the paper web has a certain elasticity and adaptability to surface textures in relation to the paper web thickness due to its multiple layers, so that the paper web adheres to the underside of the paper regardless of the number of layers The upper circumferential surface of the moistening rollers when the paper web is guided through the gap is able to rest, forming the above-mentioned Striped pattern. Therefore, the gap with its gap height, which corresponds to the distance of the lower circumferential surface of the pressure roller from the upper circumferential surface of the moistening rollers, correspond to the approximate paper web thickness of the paper web, regardless of whether the paper web is through z. B. generated as a result of the pressure roller acting on the paper web force is loaded or unloaded. The paper web, in particular the toilet paper web, is so voluminous and adaptable with regard to the gap height that it is not necessary not to adjust the spacing of the lower circumferential surface of the pressure roller to the upper circumferential surface of the moistening rollers to the multilayered paper web, which is a surprising technical fact The success of the paper dispenser according to the invention is that speaks for the easy handling and maintenance-free nature of the paper dispenser according to the invention.

On the other hand, it also proves to be advantageous that the paper web, despite its elasticity and adaptability and despite the pressure roller pressing on the paper web or touching the paper web, cannot come into flat contact with the circumferential surfaces of the recesses of the humidifying rollers, so that the alternately occurring moistened and Unwetted longitudinal sections of a strip are generated in the striped pattern of the paper web. When it is guided through the gap, the paper web tangentially touches the upper circumferential surfaces of the moistening rollers, that is to say facing away from the underside of the container, with the exception of those of the recesses. The touch area extends along the axis of rotation of the moistening rollers.

In one embodiment of the paper dispensing device according to the invention, the pressure roller is rotatably mounted in brackets on the side walls of the lid or in brackets on the side walls of the container; the axis of rotation of the pressure roller can be arranged above the axis of rotation of the moistening rollers or in the area between the moistening rollers or their axes of rotation and the rear wall of the container. The pressure roller can be arranged in holders of the container in such a way that its lower circumferential surface is aligned directly above the upper circumferential surfaces of the moistening rollers or indeed above the upper circumferential surfaces of the moistening rollers, but offset towards the rear wall.

For example, in the edges of the side walls of the container delimiting the opening, at least two brackets can be attached in order to mount the pressure roller in brackets in the side walls rotatably above the moistening rollers or laterally offset from them, as required.

It is very advantageous that the degree of moistening of the paper web can also be controlled by the user by increasing the speed at which the paper web is pulled out of the container by the user; The increase in speed surprisingly shortens the unmoistened longitudinal sections of the strips, so that the paper web has a greater degree of moistening with liquid. In contrast to the prior art, all that is required is the faster peeling off of the paper web from the paper roll in order to obtain a wetter paper web.

This unexpected advantage of the paper dispenser device according to the invention with the speed-dependent degree of paper web moistening ideally adapts to the requirement in practice to provide more paper web more quickly in the case of higher soiling, with more moisture content for the purpose of intensive cleaning.

The paper web is advantageously torn off via a tear edge which is located above the edge of the front wall and which is part of the lid that can be closed off the container.

In a further embodiment of the paper dispenser device according to the invention, the liquid in the container can be heated to a predetermined temperature, e.g. B. body temperature, be heated.

In another embodiment of the paper dispenser device according to the invention, the moistening rollers can also have a heating device, so that the rotating surfaces of the moistening rollers are heated in a cost-saving manner only by the rotational movement of the moistening rollers become.

The heating device can, for example, also be supplied with electrical power via batteries that store electrical power.

It also shows another very decisive advantage of the paper dispenser according to the invention due to the fact that the paper web remains in the gap between the lower circumferential surface of the pressure roller and the upper circumferential surface of the moistening rollers due to the stoppage of the pulling out of the paper web, but the one remaining in the gap is nevertheless able to Paper web no longer suck in liquid, since the liquid immediately withdraws due to the standstill of the moistening rollers in the absence of a rotational movement of the same in the direction of the liquid in the container and no further liquid suction takes place. Only through the rotating movement of the moistening rollers can the liquid be carried along by the revolving surfaces of the moistening rollers and remain stuck on it either until the paper web is wetted or until the rotating movement comes to a standstill.

The withdrawal of the liquid from the circumferential surfaces of the moistening rollers in the direction of the liquid stored in the container is noticeably supported by the surface-active substances in the liquid, which support the removal of dirt from the surfaces to be cleaned or disinfected.

In another embodiment of the maintenance-free paper dispenser device for the uncomplicated and reliable provision of a moistened and non-moistened paper web, its container for receiving the liquid, in particular the cleaning liquid, is pivotably mounted in or on a pivoting device which is U-shaped. The two legs, which are spaced apart from one another and aligned parallel to one another, are connected to one another via a lower section. The lower section is placed against a wall and attached to it. The pressure roller, which can be inserted from above into at least a part of the interior of the container, is rotatably mounted on the two upper ends of the two legs facing the opening of the container. The upper ends have brackets for receiving the free ends of the shaft of the pressure roller.

In the normal position of the container, the container remains in a stable position hanging on brackets of the pivoting device due to its own weight or its force of gravity. In the normal position for dispensing the non-moistened paper web, it can be pulled off the paper roll and guided between the two legs over the edge of the rear wall of the container, spaced from the upper circumferential surfaces of the moistening rollers and over the edge of the front wall of the container. In which Transition from the humidification to the normal position, the lower circumferential surface of the pressure roller is located above a straight line connecting the upper circumferential surface of the humidifying rollers and the edge of the rear wall of the container or above the straight line formed by the upper peripheral surface of the humidifying rollers and the edge of the rear wall of the container, preferably vertical, plane.

During the transition from the normal position to the moistening position, the container can easily be operated directly by the user or by a e.g. B. triggered by hand movement, sensor or touch-controlled pivoting in the direction of the wall or the section of the pivoting device, so that the two ends of the legs engage with the pressure roller so far in the direction of the interior of the container that the pressure roller with its lower circumferential surface presses the paper web against the upper circumferential surfaces of the moistening rollers and the paper web comes into flat, preferably tangential, contact with the upper circumferential surfaces of the moistening rollers. In the moistening position, the lower circumferential surface of the pressure roller is arranged below or below the straight line connecting the upper circumferential surface of the moistening rollers and the edge of the rear wall of the container or below or below the, preferably vertical, plane in which the upper circumferential surface of the dampening rollers and the edge the rear wall of the container.

As a result of the paper web being pulled through the gap, the paper web is wetted with the formation of stripe patterns due to the circumferential surfaces of the moistening rollers wetted with the liquid. When the force is no longer available, the container can automatically pivot back from its moistening position into its stable normal position for dispensing the unmoistened paper web, if necessary. The normal position is called stable insofar as the container is only held in its predetermined position by gravity in holders of the pivoting device; on the other hand, the moistening position is to be described as unstable insofar as the container is only moved from the normal to the moistening position due to the application of force, the duration of which can depend on the duration of the application of force.

In addition, the paper web according to the invention comprises a striped pattern with four stripes, which run parallel to the central longitudinal axis of the paper web, are equally spaced from one another, with each strip having alternately occurring moistened and non-moistened longitudinal sections. The ratio of the width of the paper web to the width of a strip can advantageously be 40 to 4, preferably 20 to 5, even more preferably 20, 12.5 or 10.

The paper web according to the invention, which with the aid of the invention Paper dispenser device is provided, has exceptional cleaning properties while maintaining sufficient tear resistance of the same, so that the paper web according to the invention is suitable for any areas, e.g. B. in hotels, private households, industry, laboratories, hospitals, crafts, etc. can be used.

The circumferential surfaces of the dampening rollers, which run parallel to the axis of rotation of the dampening rollers 11 , correspond to the width of the paper web 4. In the upper region of the side walls of the container, two holes are milled into which the ends of the shaft of the pressure roller 3 are rotatably mounted.

In one embodiment, the shaft of the pressure roller 3 has two shaft parts which are resiliently connected to one another in such a way that the insertion of the ends of the shaft is facilitated by sliding the shaft parts into one another.

The lower circumferential surface 7 of the pressure roller 3 is at a constant distance from the upper circumferential surface 14a of the dampening rollers 11 so that a gap 9 is provided for the passage of the paper web 4 , so that the paper web 4 tangentially flat against the lower circumferential surface 7 of the pressure roller 3 and against the upper circumferential surfaces 14a of the moistening rollers 11 are able to apply.

Below or below the container 1 , a paper roll is rotatably arranged in a receiving device. In one embodiment, the receiving device is a U-shaped bracket which is rotatably articulated in the lower region of the container 1 with its one leg, the other leg of which is received by the interior of the paper roll 5 .

With the help of this embodiment of the paper dispenser device according to the invention, the paper web is guided by unwinding over the edge 13 of the rear wall 14 of the container 1 , through the gap 9 which bridges the lower circumferential surface 7 of the pressure roller 3 and the upper circumferential surfaces 14a of the moistening rollers 11 , pulled through and over the edge 2 of the front wall 15 of the container 1 is drawn in the direction of the tear-off edge of the lid. By passing the paper web 4, the pressure roll 3 and the wet rollers 11 are rotated so that the circumferential surfaces 14a of the wet rollers 11 are wetted with the cleaning liquid and the cleaning liquid is transferred from the surfaces of revolution 14a which is arranged on them the paper web. 4

As a result of the recesses 10 of the moistening rollers 11 , non-moistened longitudinal sections are shown on the paper web 4 , which remain dry. The four dampening rollers provide a striped pattern of the paper web in which four parallel strips are formed, each strip having alternating dry and wetted longitudinal sections.

The length of the unhumidified longitudinal portions of each strip on the one hand to the axis of rotation of the wet rollers 11 extending peripheral surface of the recess 11 and on the other hand, drawn out from the rate at which paper web 4 from the container 1 depending on the.

The pressure roller 3 rests constantly on the moistening rollers 11 is the paper to be moistened 4. By pulling the paper web 4 from the paper roll 5 and the pressure of the pressure roller 3, preferably vertically, on the moistening rollers 11, the moistening rollers 11 rotate and convey a film of liquid from the container 1 upwards. The moistening rollers 11 have recesses 10 so that the paper web 4 does not get a moisture streak through it, but rather to retain the durability of the paper web 4 after it has been moistened. The result is a striped pattern, also known as a network pattern.

You can determine the degree of humidification yourself through the speed of the Paper peeling. Pulling it off slowly means less moisture, removing it quickly means a lot of moisture. After moistening by peeling off, you should slowly peel off the length of the sheet and then tear off the paper web 4 at the dry area. The pressure roller 3 comes to rest on a relatively dry section of paper, and this prevents the paper web 4 from becoming soaked in the pressure area.

In one embodiment (not shown) the pressure roller is designed as a sliding shoe which is rigidly connected to a rail, the ends of which are held in holders on the inside of the side walls of the container 1 . With its to wet rollers 11 facing support face 7, the pressure roller 3 may correspond in their function of Papierbahnandrückens against the wet rollers 11 of the lower surface of revolution 7, the paper web 4 is placed against the upper surfaces of revolution 14a of the wet rollers 11 for wetting of the paper web. 4
