The second sheet-like area product is in the context of the invention, a surface product, which is introduced in particular to reserve in the output device. Thus, the second web-shaped surface product is not threaded into the conveyor unit or promoted by this as long as the first sheet-shaped surface product is not used up. Advantageously, as soon as the first web-shaped area product has been used up, the second web-shaped area product is threaded into the conveying unit by means of the loading device and can be conveyed or dispensed therefrom. Advantageously, however, only the second web-shaped area product can be introduced into the dispensing device during the first loading of the dispensing device, wherein at this time no first, already conveyed web-shaped area product is present in the dispensing device. The newly introduced second web-shaped surface product is then automatically threaded by the loading device, so that it can be output. In a particularly preferred embodiment, it is provided that the loading arm is in the active position exclusively when no surface product is on the drum or when no surface product is detected on the drum.

According to a further embodiment, it is provided that the sensor unit comprises at least one sensor finger, which detects a surface product on the drum.

According to another variant, the surface product is guided over the first arm, in particular guided so stretched over the first arm, that the surface product applies the force to the first arm. Hereby, an alternative variant is shown, which causes the sensor arm to tilt into the first position, which indicates that web-shaped material is conveyed, this alternative variant being combinable with that of the provision of at least one sensor finger. In a further variant, it is provided that the sensor unit tilts without force on the first arm in a second position. As soon as, for example, the tension in the web-shaped surface product decreases significantly, and Thus, no force is exerted on the first arm, especially when the sheet-shaped surface product breaks off from a roll core, the sensor arm is taught that no or no more sufficient area product is available. The sensor arm thus tilts to the second position and causes the loading arm to thread surface product from the second roll.

The loading arm is preferably acted upon by a force in the direction of the drum. Preferably, the loading arm is acted upon by a spring force, which urges the loading arm in an active position. Further preferably, the loading arm is provided with at least one spring, preferably two springs, more preferably more than two springs which push or pull the loading arm in the direction of the active position.

In a further embodiment, it is provided that the sensor unit in the second position relieves the loading arm so that it can be moved to the active position. Preferably, the loading arm can be guided by means of at least one spring into the active position. Advantageously, the at least one spring exerts sufficient force on the loading arm, so that the loading arm presses the web-shaped surface product with a sufficient force to the drum, so that in particular provided with a rubber for a static friction drum or the drum shell in a rotational movement desbeziehungsweise the same supports web-shaped surface product. Preferably, the loading arm of the web-shaped surface product threads between a pressure roller of the conveyor unit and the drum.

Advantageously, the loading arm is arranged and / or shaped such that it presses the surface product between the pressure roller and the drum.

In a further embodiment, it is provided that the sensor unit acts in particular in the first position via a control unit on the loading arm.

The control unit, which is preferably arranged directly on the sensor unit, is preferably designed as an actuating means for the loading arm. In particular, the sensor unit actuates the control unit, so that the loading arm is deflected. The control unit is preferably arranged between the sensor unit and the loading arm, so that this enables a power transmission from the sensor unit to the loading arm. The control unit actuates the loading arm in particular via an actuating lever which is connected to the loading arm or is part of the loading arm. In one embodiment, the operating lever is part of the control unit. Furthermore, it is advantageously provided that a leverage between sensor unit and loading arm is exercised by the control unit. The control unit can be designed according to a further embodiment such that, for example, by the leverage a path is reinforced. In particular, this means that at a small deflection of the sensor unit, ie a small pivoting or a small pivoting of the sensor unit, the control unit acts on the loading arm such that the loading arm is further moved away from the drum or pressed, as it made the rash of the sensor unit would have. In a further embodiment, it is provided that the control unit increases the force exerted by the sensor unit by means of a lever effect. Preferably, the control unit is designed such that on the one hand sufficient force is exerted on the loading arm to effect a deflection of the loading arm against a force, in particular spring force, in the direction of an active position. More preferably, it is provided that the control unit is designed such that the loading arm is sufficiently far out in the passive position, so that in particular the second sheet-shaped surface product is not accidentally threaded.

Particularly preferably, the control unit is designed such that both a sufficient force on the loading arm and a sufficient deflection of the loading arm takes place.

In a further embodiment it is provided that the loading arm is mounted on the cover part. This has the advantage that the einzahnelnde surface product must be unrolled from the role only a piece until it hangs in the sphere of influence of the loading arm. Since the loading arm is arranged on the cover part, no threading between loading arm and drum is necessary. It is sufficient to open the lid part. If the lid is closed, the loading arm can immediately, if no surface product be on the drum to be promoted or thread the newly inserted surface product in the conveyor.

Furthermore, a method for threading a surface product to be dispensed into a delivery unit of a dispensing device is proposed, wherein the dispensing device comprises a housing part, a cover part and the delivery unit. The conveyor unit further comprises a drum, wherein the drum is associated with a loading device and the loading device comprises at least one loading arm. A roll with a sheet-like surface product is introduced into the dispenser, so that the sheet-like surface product is arranged between the loading arm and the drum. Detects, for example, the sensor device that no surface product is no longer present on the drum, this tilts in the second position, the control unit is relieved or moved by the loading arm and in particular withdrawn. Since the loading arm is now relieved, this is brought into the active position and pushes the web-shaped surface product against the drum. Preferably, the loading arm pushes the web-shaped surface product against the drum so that the drum promotes the surface product upon rotation of the drum.

In one embodiment, it is provided that a first roller with a first web-shaped surface product and a second roller with a second web-shaped surface product is introduced into the dispensing device, so that at least the second web-shaped surface product is arranged between the loading arm and the drum. Preferably, the second roll is introduced with the second surface product when the first sheet product is already threaded.

In a further embodiment, it is provided that the loading device has a sensor unit, by means of which a web-shaped surface product is detected on the drum. In particular, an embodiment provides that the sensor unit comprises at least one sensor finger, which corresponds to at least one groove in the drum, wherein a surface product on the drum lifts the sensor finger out of the groove. The sensor finger is preferably designed such that a newly threaded surface product can slide between the sensor finger and the drum.

In particular, a pressure roller is arranged such that the surface product is threaded between the drum and the sensor finger. Furthermore, the force exerted by the sensor finger on the drum or on the groove of the drum, moreover advantageously on the surface product, which is located between the sensor finger and drum, is selected such that the surface product does not crack, not blocked and especially not in the Groove is pressed.

According to one embodiment, the pressure roller is positioned to the drum so that it has a distance of about 0.01 mm to about 1 mm. In a further preferred embodiment, the pressure roller is designed such that it rests directly on the drum or can rest. A further embodiment provides that the pressure roller is designed to be movable.

In an alternative embodiment, which can be combined with the embodiment with at least one sensor finger, it is provided that the first web-shaped surface product is guided in such a tensioned manner over a first arm of the sensor unit that the Sensor unit acts directly or indirectly on the loading arm, that this remains in an inactive position in which the loading arm is pivoted away from the drum. Advantageously, the loading arm is pivoted away from the drum so that it does not act on the second sheet-shaped surface product.

In a further embodiment it is provided that the sensor unit is tilted into a first position by a force which is exerted on the first arm by the first sheet-like surface product which is stretched over the first arm of the sensor unit. Advantageously, it is provided in a further embodiment that the sensor unit is tilted in unloaded first arm in a second position.

In a further variant, it is provided that, in the case of a loss of tension of the first web-shaped surface product, in particular when the first web-shaped surface product is torn off from the reel core or from the sleeve on which the web-shaped surface product is wound, the sensor unit relieves the loading arm, so that the same is relieved an active position is pivoted so that the second sheet-like surface product is at least partially pressed against the drum by means of the loading arm.

According to a further embodiment it is provided that either the sensor unit detected by the loading of the first arm by the first web-shaped surface product, a voltage in the surface product or by means of at least one sensor finger, which corresponds to at least one groove on the drum, the promotion of the surface product on the drum detected. An advantage of the detection by means of the sensor finger is that the sensor unit or the control unit can only then transfer the loading arm into the active position, when in fact no web-shaped surface product is conveyed on the drum. An advantage of the embodiment in which a force is exerted on the first arm by means of the tension of the web-shaped first surface product, is that the second web-shaped surface product is already promoted when surface product is still on the drum. This can be an advantage if you want to prevent a user from coming to the wrong conclusion Output device is empty. However, in this embodiment, at least for the output of the remainder of the first surface product after this stress separation and the second surface product mitausgegeben. In a further variant, it is proposed to combine these two detection methods.

According to a further embodiment it is provided that at least one guide means, in particular at least one rib, is provided on the sensor unit. Preferably, a number of guide means are provided on the sensor unit. In particular, the guide means are designed such that they guide the web-shaped surface product on the drum.

In a further embodiment it is provided that by means of the sensor unit, a control unit is moved, which moves the loading arm in an inactive position. The sensor unit acts mechanically on the control unit, which in turn acts on the loading arm. According to one embodiment, the control unit is designed such that it amplifies the force transmitted by the sensor unit by means of a lever mechanism or increases the distance traveled by the sensor unit. Furthermore, the control unit may be designed such that the direction of movement of the force exerted by the sensor unit on the control unit is changed in its effective direction. For example, it is provided that the sensor unit tilts and thus exerts a moment on the control unit. The control unit, like the sensor unit, is pivotally mounted, preferably connected to it, so that a lever effect occurs by force exerted by the sensor unit on the control unit, preferably an enlargement of a described angle of the sensor unit. In a further embodiment it is provided that the force on the loading arm is increased by means of the leverage of the control unit. The control unit is mounted according to an embodiment on the same axis as the sensor unit. In a further variant, it is provided that the control unit is non-positively connected to the sensor unit by means of a spring, in particular a torsion spring.

A further embodiment provides that the web-shaped surface product is placed on at least the first arm of the sensor unit by reducing the roller diameter D _R by means of a roller guide. According to one embodiment, the roller guide is designed such that, in particular as a function of a roller diameter, it guides the roller on a predetermined path through the interior of the dispensing device. In particular, the roller guide is designed so that, after consumption of the sheet-like surface product has taken place from the roll, the roll is transferred to a position in which another role can be inserted into the dispenser.

The present invention further relates to an output device for dispensing a sheet-like surface product from a roll comprising at least a housing part and a roller guide. The roller guide comprises at least a first tread and a second opposing tread. Both treads form an inclined plane in the operating state of the output device.

For the purposes of the invention, the operating state of the dispensing device is a state in which the dispenser is visibly upright, for example, on a wall, for the person skilled in the art.

In a further embodiment it is provided that the planes are arranged in particular such that the roller with decreasing roller blade D _R slips down the running surfaces.

The dispenser may, according to one embodiment, receive a roll of web-shaped sheet product which is coreless or core-finished. A coreless roll is in particular a winding of surface product which is not rolled up on a core or a winding or a coil or a sleeve. According to one embodiment, such a coreless roll has insertion parts which are introduced in particular into a cavity of the roll. These inserts protrude, for example via cylindrical projections beyond the longitudinal extent of the role and can according to a further embodiment have rolling surfaces. These rolling surfaces are particularly suitable for unrolling on the running surfaces of the dispenser. In a further preferred embodiment it is provided that the roller has a roll core or sleeve. This roll core or sleeve can for example be made of plastic, cardboard or any other material or material mixture. In a further embodiment, it is provided that the roll core or sleeve has one or more separations. In particular, the roll core can be configured such that, as soon as the sheet material is removed from the roll core, it breaks up into several parts. This embodiment is called in technical jargon "split core". The design of the roll with a roll core can be designed according to one embodiment such that inserts are embedded in particular in the roll core or inserted, glued and / or clamped. According to a further preferred embodiment, it is provided that the insertion parts, which are inserted on both sides into the roll core or into the roll, differ in their design. It is preferably provided that a first insertion part has a smaller rolling diameter, provided, for example, by the cylindrical projections, as a second insertion part. Preferably, the dispensing device is designed such that the insert parts run on the treads in such a way, can roll or slip down, without causing the role in the output device tilted or unrolled.

An advantage of the embodiment with two different running surfaces is that it can be predetermined on the production side in which orientation the roll can be inserted into the dispensing device. In particular, it is provided that the first running surface is designed such that it is not able to accommodate the second insert part. Inserting the roll with a wrong orientation is therefore not possible. The orientation is particularly important for the correct introduction of the sheet-like surface product between a drum and a loading arm, as explained above in connection with the further invention. Also, in a further embodiment of Output device, the orientation of the sheet-like surface product is important to avoid jamming or tilting of the surface product in the output.

In a further embodiment of the dispensing device it is provided that the running surfaces are inclined towards a rear wall or a limiting device. In particular, the limiting device is assigned to the rear wall or arranged thereon. Preferably, it is provided that the inserted roller rolls down the running surfaces so far or slips until an outer periphery of the roller bears against the rear wall and / or the limiting device. The advantage of this embodiment is that, as the consumption of the sheet-like surface product increases, which leads to the roll diameter becoming smaller, the roll always bears against the rear wall or limiting device at least up to a predetermined roll diameter. The insert part or the roller runs down on the running surfaces.

In a further embodiment, it is provided that the dispensing device has at least one limiting device which is configured such that the roller arranged in the roller guide is prevented from slipping down on the running surfaces by the limiting device and depending on a roller diameter. The limiting device is arranged according to an embodiment on the rear wall of the housing. Further advantageously, the limiting device is a part of the rear wall of the housing. Further advantageously, the limiting device is configured such that the roller can slide on it. More preferably, an embodiment is provided in which the limiting device is designed such that it guides the roller in dependence on the roll diameter and / or holds in position.

The running surfaces are in particular designed such that unrolling of the surface product from the roll is easily possible. For this purpose, a plastic is preferably selected, which has a low frictional resistance matching the rolling surfaces of the insert parts. Furthermore, it is provided according to a preferred embodiment that the Clamping device is made of a material or coated with a material having a low frictional resistance with the surface product. The limiting device is configured geometrically such that the smallest possible surface presses against the surface product, without an excessive denting of the surface product by the limiting device. Preferably, at least the limiting device, at least one surface thereof facing the roll, and / or the treads comprise a material selected from a group comprising polyolefin, polyoxymethylene (POM), a polystyrene (PS) and / or a polyethylene (PE).

According to a further embodiment, it is provided that the roller guide comprises a tolerance compensation at least on one side. This has the advantage that with a different linear expansion of the individual rollers, the respective roller can be correctly inserted into the dispenser.

The rollers are provided with tolerances due to their production. In particular, tolerances in the range of the length of the roll are common. Furthermore, production-related often means that, when these insertion parts are provided, they are inserted differently far into the roll core or into the roll, so that they protrude differently far beyond the roll length. It is well known in the art to provide a rigid receptacle for the rollers. This has proved to be disadvantageous since the roller, should it have a longitudinal extent below a tolerance range of only small dimensions, slips out of the roller guide and in particular of the running surfaces. This leads to tilting of the roll within the dispenser and the roll can not be used further, or the output device can not spend another surface product.

A variant provides that the tolerance range comprises at least the second tread, which can be issued in a lateral orientation. In the lateral direction, in particular in the longitudinal direction of the roller. That is, the tolerance range is according to an embodiment designed so that this, should the roller does not have the maximum permissible longitudinal extent, in particular less than the maximum intended longitudinal extent, the at least second tread in the direction of the role, that is issued in the lateral direction of the dispenser, so that the role still on or the rolling surface of the insert parts can still roll on the treads. An exhibition in the lateral direction may also include tilting or tilting of the tread, in particular the second tread, in the direction of the roller or housing center.

In a preferred embodiment, it is provided that the tolerance range is resiliently mounted. In particular, at least one leaf spring is provided, which causes the exhibiting of the tolerance compensation or the second tread. In other embodiments, other spring mechanisms, in particular at least one torsion spring or at least one helical pressure fields, are provided. According to a further embodiment it is provided that the spring comprises at least one material selected from a group comprising a metal or a plastic, in particular polyoxymethylene (POM).

In a further embodiment it is provided that the tolerance compensation is articulated on a lateral wall, for example, a side wall and / or insert wall. The tolerance compensation, which has at least one tread, can be configured as a flap or rocker similar. This allows easy handling especially when inserting the roll. If the tolerance compensation, for example, resiliently mounted, this is preferably moved when inserting the roller in its center of the housing facing position and then placed the role on the tread of the tolerance compensation and subsequently placed on the opposite tread. As a result, for example, the laying of the opposite insert in or on the opposite tread tolerance compensation is issued in particular by means of the spring so far that the rolling surface of the tolerance compensation associated insert can roll on the tread of the tolerance compensation. In particular, it is provided that the tolerance compensation is issued so far that this at least partially on the role or its insert rests. According to one embodiment, the tolerance compensation is designed such that it brakes the roller, in particular in order to achieve optimum tension of the surface product.

More preferably, the insert part and / or an end face of the roller presses the tolerance compensation in the optimum position.

Furthermore, a method for guiding a roll in an output device is proposed. A roll having a sheet-like surface product is placed on or in a roll guide comprising at least two treads forming an inclined plane. The roller rests at least partially on the running surfaces and is guided along the roller guide as a function of a roller diameter D _R. In particular, the roller is inserted into the dispensing device such that the insertion parts or the rolling surfaces of the insertion parts of the roller rest on the running surfaces.

In a further embodiment it is provided that the roller guide comprises a limiting device and the roller is supported by means of the limiting device. Furthermore, it is provided in one embodiment that the role is guided down the rolling surfaces depending on the roll diameter D _R or rolls down.

According to a further embodiment, it is provided that the roller is transferred after falling below a certain roller diameter D _R of the treads in a residual role recording.

In particular, this is to be understood as a tolerance range of +/- 20%, preferably +/- 10%, more preferably +/- 5%.

The role used in the receiving device is arranged according to an embodiment in a first step on the running surfaces of the roller guide. When the sheet-like surface product is unwound from the roll, the roll slowly slips down the running surfaces. According to a preferred embodiment, the running surfaces terminate at a defined distance from the rear wall or from the limiting device. If the roller falls below a diameter, preferably a radius which corresponds to the distance between one end of the running surfaces and the delimiting device, the remaining roller falls through the gap between the running surfaces and the delimiting device or rear wall. In particular, if a radius of the roller plus the radius of at least one insert part or a sleeve is smaller than the distance between one end of the treads and the limiting device, the remaining roll falls through the gap between the running surfaces and the limiting device or rear wall.

The surface product is cut through cleanly and not torn. Even with a quick processing of the surface product on the drum and an associated rapid cutting movement through the knife a clean cut is performed. Another advantage of the described embodiment of the dispenser with cutting device is that despite the complex movement of the knife, a low friction by the operation of the knife holder by means of the cam and cam track takes place. Thus, it does not require high forces or moments to rotate the drum, or to convey the surface product from the dispenser. This supports a clean cut. The system is also very robust, which means that in contrast to the known from the prior art for surface products output devices jamming of the knife at the output is largely prevented. A further advantage is that the system is very simple and few moving parts are present in the cutting device. In addition, the proposed output device is fault-tolerant and inexpensive to produce.

The cam track is preferably designed such that the knife carrier in a certain area or at a certain angle of rotation of the drum at least partially moved radially to the drum. Due to the radial movement of the knife holder, the knife is at least partially moved outside the drum. For the purposes of the invention, a radial movement is here also understood to mean a movement which, in particular, is offset parallel to a radius or parallel thereto. In its broadest sense, a radial movement is a movement of the knife holder, and more particularly a cutting edge of the knife, from within the drum towards the drum shell and beyond.

In a further embodiment, it is provided that the second cam extends through the second cam guide into a second cam track, which is preferably associated with the end face of the drum. For example, it can be provided that two cam tracks are partially overlapping or crossing at the end faces of the drum. Furthermore, an embodiment provides that a first cam track is located on a first end face of the drum and a second cam track is located on the second end face of the drum, is provided according to a first embodiment, that a first cam engages the first cam track and a second cam in the second cam track.

The term "substantially" or "approximately" in the sense of the present invention indicates a tolerance range which is to be represented for the expert from a technical point of view, so that the corresponding feature can still be recognized as such. In particular, this is to be understood as a tolerance range of +/- 20%, preferably +/- 10%, more preferably +/- 5%.

The drive unit comprises at least one actuating means and at least one associated drive train, which is connected to the drum, wherein the drive train comprises at least one freewheel.

Advantage of the output device with freewheel is that the drum is driven by means of the actuating means in one direction only. In particular, when returning the actuating means is prevented by the freewheel that a reverse rotation of the drum takes place, which would, for example, a retraction of the web-shaped surface product result.

For the purposes of the invention, a freewheel comprises different types of freewheeling or devices which enable freewheeling. At least is under a freewheel a pinch roller freewheel, a sprag freewheel, a pulley freewheel and / or a wrap spring free to understand.

In one embodiment, it is provided that the drive train comprises at least one rack, which is associated with the actuating means. In a further embodiment it is provided that the actuating means are assigned two, three or more than three racks, which engage in a respective drive train. The rack is in particular firmly connected to the actuating means or designed in one piece with this.

In a further embodiment it is provided that the rack is in engagement with a pinion, which is connected via a freewheel with other components of the drive train. In particular, it is provided that the actuating means has at least two racks, each of which is in engagement with a pinion. Advantageously, the two pinions are interconnected via a shaft. In particular, the pinions are part of a respective drive train. Preferably, according to one embodiment, it is provided that at least two drive trains are assigned to the actuating means, each of which drives the drum. This has the advantage that when the drive trains are arranged on both sides of the actuating means, a uniform force is applied to the drive trains and thus into the drum.

In a further embodiment it is provided that at least one drive train comprises a return mechanism, by means of which the drum is rotated to a basic position. The basic position is in particular a position in which the knife or the knife carrier remains in the drum in a position in which the knife does not protrude beyond the drum shell.

If the drum remains in the basic position, no surface product is conveyed. Particularly advantageous is provided that in a single actuation of the actuating means, the drum performs a complete revolution, in particular, the return mechanism ensures that the drum performs a complete revolution, even if by the force of the actuator in the drive train only a partial, in particular about half, preferably more than a half, more preferably about a three-quarter turn of the drum is performed.

A further embodiment provides that the return mechanism comprises at least one spring. Preferably, the return mechanism comprises at least one bending field and at least one deflection.

The lever is connected according to an embodiment with a polygonal insert part, which is insertable into a corresponding receptacle in the drive train. Preferably, the polygonal insert is uniform, preferably designed star-shaped. This embodiment has the advantage that springs with different spring constants or spring lengths, which are due in particular to manufacturing tolerances, can be used. In the assembly of the dispenser, a bias of the spring can be adjusted by the polygonal insert is rotated in accordance with the recording set. Furthermore, it is provided according to an embodiment that the springs are arranged such that a first spring causes a second partial revolution of the drum after a first partial revolution of the drum. Furthermore, it is provided in one embodiment that at least one second spring causes a third partial revolution of the drum after a second partial revolution of the drum. It is particularly preferred that the first Part turn and the second part turn a full turn.

Preferably, the first spring acts after a partial rotation of the drum from about 20 ° to about 45 °. More preferably, the second spring acts after a partial rotation of about 35 ° to about 90 °. In a further preferred embodiment, the springs act in a rotational distance of about 10 ° to about 30 °, preferably about 15 ° to about 20 °. For the purposes of the invention, the term "revolution distance" is to be understood as meaning a rotational angle by which the drum is moved, between the action of the first spring and the action of the second spring. For example, the drum is rotated a first partial revolution of about 30 ° by an operation of a user. The first spring is so biased in particular that this now rotates the drum by at least about 15 ° - the rotation distance, which corresponds to the second part of rotation in this example. The second spring is arranged, for example, such that it acts at a rotation angle of approximately 45 ° and rotates the drum approximately by a further 315 °.

A further embodiment provides that the drive train comprises a ratchet wheel and a pawl. The ratchet wheel and the pawl cooperate in such a way that during a rotation of the drum, a turning back of the drum is largely prevented, in particular by the force of the bending spring.

Furthermore, a method for driving a drum of a dispenser is proposed, wherein the dispenser comprises a conveyor unit with at least one drum and a drive unit. In this case, an actuating means of the drive unit is actuated and transmitted in particular via the actuating means introduced torque in the drive train to the drum. The actuating means is reset after actuation, wherein by means of a freewheel in the drive train, a reversal of the direction of rotation of the drum is prevented.

By folding up the cover part of the dispensing device, it is opened in such a way that refilling with area-like products is easily possible. Thus, in the case of the proposed dispensing device during refilling no disturbing parts are present, such as to the sides or downwardly unfolded lid parts.

However, the inventors have found problems associated with folding up the lid of the dispenser. In the open state of the dispenser, a weight force acts on the lid part that is folded upwards, which causes the lid part to unintentionally fold down. In addition, the impact of force generated by the lid member contacting the sidewalls or bottom of the dispenser upon closure of the dispenser may cause material damage or injury to the user. Furthermore, when opening the dispensing device, the weight force acting on the lid part must be overcome, which requires additional effort in the form of a lifting force by the user.

The problem is solved by the fact that the opening arms are in the open position of the lid part are securely in a holding position, whereby an unintentional down-flaps of the lid part is prevented. A holding means contributes to a stabilization of the latching position and thus of the open state of the dispensing device. Furthermore, the holding means is preferably designed such that a smaller force is required to open the dispenser than to close the dispenser.

Preferably, the holding means is formed such that on an upper or lower surface of the holding means, the opening arm having at least one projection is guided past and the at least one projection of the opening arm at least partially in contact with the at least one surface of the holding means is feasible.

The holding means preferably has at least one segment. In the context of the present invention, a segment is preferably an area of the holding means which lies between at least two marked points of the holding means. The marked areas preferably have a maximum, minimum and / or inflection point or saddle point in at least one spatial direction or are start or end points of the holding means.

Preferably, the at least one segment is formed flat. The holding means preferably has at least two segments. Preferably, the holding means has at least two segments which adjoin one another.

The term maximum M in connection with the at least one holding means is to be understood beyond a strictly mathematical understanding. A maximum M in the sense of the application need not necessarily be present along all spatial directions, but at least along one spatial direction.

The holding means preferably has at least two segments which adjoin one another in such a way that a maximum M is formed. The maximum are preferably assigned to the two inner angles λ and λ ', wherein in each case one of the two angles is assigned in each case to one of the two segments forming the maximum M.

In a preferred embodiment, λ 'and λ together take a value in the linear range of about 20 ° to about 140 °, more preferably a value in the range of about 50 ° to about 140 °, even more preferably from about 70 ° to about 120 °, at.

Preferably, the angle λ 'takes on a value in the range of about 10 ° to about 70 °, more preferably a value in the range of about 25 ° to about 70 °, even more preferably from about 35 ° to about 60 °.

Such an arrangement may be regarded as a basic unit in that a plurality of such basic units can be linked to one another within a holding means. The linking of such basic units can take place either directly or indirectly through further segments. The basic units may be the same or different.

The secure closing of the dispensing device is preferably supported by at least one braking means. By the braking means, the folding down of the lid part is slowed down and thus in particular material damage is prevented, which arise from the fact that the lid part coincides with the side walls or the bottom of the dispenser in a strong impulse. If the user with his limbs, in particular with his fingers, is still between bottom portion and lid part or side walls and lid part, it is achieved that the corresponding limbs of the user experienced only a reduced force through the down-hinged lid part.

This mechanism is preferably supported by a sprung connection of the opening arms with the cover part of the dispensing device, whereby it is achieved that when the lid part is folded down, the force acting on the lid part is cushioned via the opening arms and the corresponding energy is stored as spring energy. This is also advantageous when opening the dispenser. In one embodiment, the stored spring energy is used to apply the necessary lifting force when the lid is raised.

These mounting means 222 serve to reversibly connect the locking means 210 with the output device 8 and 10, respectively. The locking means 210 can thus be replaced if necessary. Furthermore, located on the outside of the side wall 214 projections 219, which also find use as a mounting means. Preferably, the projections 219 engage in corresponding recesses or openings on the Housing part 12 on the dispenser 8 and 10, respectively, and thus fix the locking means 210 in the dispenser 8 and 10 respectively.

Fig. 17 shows an embodiment of the housing insert 250 in a perspective view. Fig. 18 shows an embodiment of the housing insert 250 in plan view. The housing insert 250 has side walls 260 which include a side wall portion 280. The side wall portion 280 is delimited from the side wall 260 by a step 286. Sidewall 280 includes a first blocking protrusion 284 and a second blocking protrusion 282 at an end facing away from sidewall 260. Blocking protrusion 282 is disposed at the outermost edge of sidewall member 280. Both projections 284 and 282 are substantially equally spaced radially from side wall 280 and have approximately the same radius with respect to central axis of rotation 240 as side wall 260. The first blocking projection 284 has chamfered areas on both sides, that is, the transition from or to the flat surface of the side wall portion 280 via an inclined plane, while the second locking projection 282 has a substantially perpendicular to the plane of the side wall portion 280 disposed side wall. The parts of the side wall 260 and in particular the side wall part 280 have no contact with the bottom 252. Advantageously, this ensures a special elasticity of the side wall part 280. When assembling the housing 212 with the housing insert 250, the projection 219 arranged in the housing 212 comes to lie on the side wall part 280.

Shown are also two return means 290 which are connected to the first and second guide pins 294.1 and 294.2 and to the central axis 240. The return means 290 forms with the side wall part 280 a substantially separated area 291, in which a fixing pin 230 can engage. Depending on the rotational orientation of the housing insert 250 to the housing 212, the position of the fixing pin 230 changes within the area 291. In the locked state, the fixing pin 230 engages in the area 291 such that the fixing pin 230 either no or only a weak contact with the return means 290 has. When transferred to the unlocked state, however, the fixing pin 230 is pressed against the return means 290. In this way, the return means 290 forms a force opposing the rotational movement of the locking means 210. In the locked state, the projection 218 is disposed immediately adjacent to the first block projection 284 of the side member 280. When transferred to the unlocked state, the housing insert 250 is moved against the housing 212 such that projection 218 is substantially moved along the surface of the sidewall portion 280 until the step 286 is reached. The step 286 thus contributes, along with the limited length (span) of the arcuate recess 232 of the housing 212, to restricting the rotation of the housing insert 250 relative to the housing 212. By the return means 290 is a provision of the locking means 210 in the locked position as soon as the key is no longer held by the user. Rotation of the housing insert 250 against the housing 212 away from the side wall 260 or step 286 toward the second locking projection 282 causes the protrusion 219 to be moved past the first blocking protrusion 284 and into the intermediate region between the first and second blocking protrusions 284, 282 comes. In contrast to the locked and unlocked state, this orientation of the housing insert 250 with respect to the locking means housing 212 corresponds to a further state of the locking means 210, for example a service position. The obliquely formed walls of the first blocking projection 284 contribute advantageously to the fact that the locked state can be converted into the service state. In particular, the return means 290 are not or hardly acted upon by a force in this position. They are preferably applied to the fixing pin 290. Thus, the oblique sidewalls of the first blocking protrusion 284 facilitate easier sliding of the protrusion 218 beyond the first blocking protrusion 284. Furthermore, it is advantageous that the side part 280 is not in direct contact with the bottom 252 of the housing insert 250, since thus the side wall part 280 is given a certain flexibility and the movement of the projection 218 when transferring the locking means 210 to the service position or the service state evades can move inwards.

Fig. 19 shows the housing insert 250 with respect to the outside of the bottom 252. The bottom 252 has a recess 254 on. The key 203 may be inserted into the recess 254 to allow rotation of the housing insert 250 about the housing 212. The figure shows that the recess 254 has a taper in the central area.

Fig. 20 shows the locking means 210 in a plan view, wherein the bottom of the housing 212 is located in the plane of the paper.

Fig. 21 is a schematic representation of three states of the locking means 210 from Fig. 20 , The perspective of the locking means 210 in FIG Fig. 21 corresponds to the Fig. 20 , However, in Fig. 21 through the bottom of the housing 212 of the locking means 210 into the interior of the locking means 210.

Fig. 21 shows the transition of a first state A of the locking means 210 to a second state B 'and to a third state B ". Preferably, state B" corresponds to an unlocked state and state B' corresponds to a service state. It is essential that the three states A, B 'and B "have different positions of the guide pins 294.1 and 294.2 and also the return means 290.1 and 290.2 By means of interaction of the first and second guide pins 294.1 and 294.2 with a suitable locking system within the dispenser, for For example, with a latch arm 805 and an engagement projection 820, the different positions of the first and second guide pins 294.1 and 294.2 can be translated into different latch states of an output device.

Starting from state A of the locking means 210, which corresponds to the locked state, by turning the housing insert 250 housing 212, for example by an inserted key 203, depending on the direction of rotation, state A can be transferred to state B 'or to state B " State A in state B ", protrusions 218 are moved away from blocking protrusion 284, wherein Fixing pins 230.1 and 230.2 are pressed against the return means 290.1 and 290.2. The return means 290.1 and 290.2 are elastically configured and not directly connected to the bottom 252, which has the consequence that the return means 290.1 and 290.2 reset state B "in state A, if the user does not have a sufficiently large counterforce by rotation of the housing insert 250 against the housing 212 exerts, or by holding a key 203 which is inserted into the locking means 210, in the position according to state B ".

State A can be converted by rotation of the housing insert 250 in an opposite direction in state B '. In order to transfer state A to state B ', the projection 218 must be pressed by the rotary movement against locking projection 284 and be moved past it. Projection 218 then comes to rest between first and second blocking projections 284 and 282.

Fig. 22 shows how the locking arm 805 in conjunction with the guide pins 294.1 and 294.2 the in Fig. 22 This translation of states A, B 'and B "of the latch means 210 into the corresponding latch states A, B' and B" of the output device will be translated into the respective latch states A, B 'and B "of the output device through the different positions of the guide pins 294.1 and 294.2 in the three states.

Latch arm 805 has side projections 808 and 809. Shown is state A of the locking means 210, wherein the lateral projection 808 is located directly on the first guide pin 294.1, the side projection 809, however, has a certain distance from the second guide pin 294.2. Upon rotation of the housing insert 250 against the latch housing 212 and transfer to a state B ", the first guide pin 294.1 presses against the side projection 808, thus moving the rotatably mounted lock arm 805 upwards By such rotational movement of the lock arm 805, the lock arm hook 807 moves from the am Cover part 12 located engagement projection 820 out, whereby the output device is transferred to an unlocked state.

Upon rotation of the housing insert 250 against the locking means housing 212 in the opposite direction to transfer state A to state B ', the first guide pin 294.1 moves downward while the second guide pin 294.2 moves upward until the second guide pin 294.2 contacts the lateral projection 809 and moves the locking arm 805 upwards. Unlike the first guide pin 294.1 with respect to the lateral projection 808, the second guide pin 294.2 in state A is not immediately below the lateral projection 809. Upon transition from state A to state B 'there is less lift of the locking arm 805 than when transferring State A in state B ".

As a result, the lock arm hook 807 does not move all the way out of the engaging projection 820 and the dispenser is in a service state B '. In this case, the Verriegelungsarmhaken 807 preferably under tension, in particular caused by the restoring force of spring 840, with the engagement projection 820. The respective surfaces which are in contact between the Verriegelungsarmhaken 807 and the engaging projection 820, are significantly smaller than in the locked state , By moving the cover member, the user can release the contact of latch arm hook 807 and engagement tab 820 and unlock the dispenser therewith

Fig. 23 shows the interaction between locking arm 805 and engaging projection 820 for the locking states A, B 'and B "in a side view of an output device.

Fig. 24 shows an alternative embodiment of a locking means 210 and the interaction of the locking means 210 with a removable engagement member 849, as can be used in the dispensing device 8. The locking means 210 can be arranged on the head part on the cover part 12. In Fig. 24 is the locking means 210 together with the engagement portion 849 in a rear view A and in a front view B shown. The engagement member 849 includes engagement means 850, which is the forward end of the engagement member 849, and attachment means 870, which is the rearward portion of the engagement member 849. The engagement means 850 in turn comprises arms 856.1 and 856.2 with engagement hooks 852.1 and 852.2 and fastening projections 854.1 and 854.2. The fastening means 870, that is, the rear end of the engaging part 849, has fastening elements 872.1 and 872.2 which have a hook-like shape. As seen from the top view Fig. 24B can be seen, fastening means 870 also has a fastening projection 874.

In Fig. 24 is a movement of the first and second guide pins 294.1 and 294.2 illustrated by dashed arrows. By the force of the first and second guide pins 294.1 and 294.2, the arms 856.1 and 856.2 of the engagement means 850 are compressed. When the dispenser 8 is in a locked state, engagement hooks 852.1 and 852.2 located at the extreme end of engaging means 850 interact with a fastener 870 disposed on the housing member 14 of the dispenser 8. In this case engagement hooks 852.1 and 852.2 interact with engaging pins 892.1 and 892.2 laterally arranged on receiving part 890 so that dispensing device 10 is locked and can not be opened (see FIG. 39). By compressing the engagement hooks 852.1 and 852.2 as described above, the connection of the engagement hooks 852.1 and 852.2 with the engagement pins 892.1 and 892.2 may be released, and the output device 8 is transferred to an unlocked state. The user can now open the dispenser 8 via a movement of the lid part 12. Locking means 210 is connected to the engaging part 849 in the described embodiment by an engaging ring 893 such that the engaging ring 893 connected to the locking means 210 is pushed with its side edges over the arms 856.1 and 856.2 of engagement means 850 and thus a clamping connection is produced.

Fig. 25 shows the embodiment of the locking means 210 together with the engaging member 849 in side view. Out Fig. 25 It can be seen that the fastening means 870 and the engagement member 849 are oriented angled to each other. This does not apply to the engagement hooks 852, which are oriented substantially parallel to the fastening means 870 on the housing part 14. Furthermore, it is off Fig. 25 it can be seen that the fastening projection 854 is arranged on the opposite side to the side on which the locking means 210 is arranged. On the other hand, the fastening projection 874 is arranged on the same side of the engaging part 849 as the locking means 210. The fastening projection 874 and fastening projection 854 serve for fastening and arranging the engagement part 849 with locking means 210 on the dispensing device 8. By the opposite arrangement of said fastening means and with respect to FIG On the sides of the engagement part 849, the engagement part 849 can be attached to the dispenser 8 on two sides. Furthermore, the fastening element 872 serves for the stable, preferably detachable, attachment of the engagement part 849 to the dispensing device 5.

Fig. 26 shows the arrangement of locking means 210 with engagement portion 849 on a cover part 12 of the dispensing device 8. In this case locking means 210 is connected via mounting means 222.1 and 222.2 directly to the cover part 12. Further, latching means 210 is immediately engageable with engaging portion 849, as in FIG Figs. 27A and B shown, wherein engagement member 849 is connected to a frame part 880, via the fasteners 872.1 and 872.2 and via the mounting projections 854.1 and 854.2. The engagement part 849 is directly connected to the cover part 12 via the fastening projection 874. In particular, the engagement part 850 is arranged on the cover part 12 of the output device 8 in such a way that the engagement hooks 852.1 and 852.2 of the front engagement means 850 project from the contour of the cover part 12. By rotating the housing insert 250 against the housing 212, guide pins 294.1 and 294.2 are pressed against the arms 856.1 and 856.2 of engagement means 850 of the engagement member 849. The frame part 880 is detachably connected to the lid part 12.

Fig. 27 shows an embodiment of the dispensing device 5 and how a locking means 210, consisting of a housing 212 and a housing insert 250, is introduced into a bore 211 on the side wall 20 of the housing part 14 of the dispensing device 5. 51A shows the complete housing part 14 in a perspective view, while FIG. 51B shows the assembly of the housing 212 and housing insert 250 into the bore 211 in detail. Out Fig. 27 shows that the locking means 210 is inserted into the bore 211, such that the housing 212 comes to the outside, that is directly on the edges of the bore 211 comes to rest. The locking means 210 can be inserted into the bore 211 in two different ways. Thus, on the one hand it is possible first to insert the housing 212 into the bore 211 and then insert the housing insert 250 into the housing 212 in a second step. Alternatively, in a first step locking means 210 may be assembled by inserting the housing insert 250 into the housing 212, followed by the insertion of the locking means 210 in the bore 211 in a second step.

FIGS. 28 to 32 show an embodiment of the dispenser 10 with different guidance of the surface product 26. The roller 28 with the surface product 26 is inserted in this embodiment with a unwinding direction to the rear in the dispenser 10. In particular, the embodiments of the dispenser 10 correspond to Fig. 2 to Fig. 4 the embodiments of the FIGS. 28 to 30 each with opposite rolling direction of the roller 28 and the rollers 28.1 and 28.2.
