Abstract

The dispenser (10) has an elongated-shaped box in which a tubular-shaped roller (4') and another roller of a paper strip are housed. The box comprises a base (5) with housings for respectively receiving the rollers. Doors (1, 1') are mounted on the base and arranged for respectively protecting the rollers in a closing position and accessing the housings in an opening position for individually reloading the rollers. The doors comprise respective nozzles (3, 3') for dispensing the paper strips from the rollers. The doors are connected to the base by pivoting units i.e. oblique hinges.

Description

The invention relates to a paper dispenser in which at least two rollers are accommodated. The invention finds application more particularly in dispensers of absorbent paper, for example dispenser of toilet paper and wiping paper.

In public places, in particular, the toilet paper dispensers generally comprise a housing, in which is mounted a roll of a strip of toilet paper which is unwound by a dispensing orifice.

The paper strip has pre-cuts transverse to the direction of its unwinding, defining rectangular sheets that can be detached individually. The toilet paper is a cellulose wadding paper, flexible and soft surface, comprising one or more plies whose weight is usually between 14g / cm2 and 30g / cm2 approximately.

The most common dispensers include an opening, or window, at least the width of the toilet paper, arranged in a low position on the dispenser, by which the paper is unwound. The unwinding takes place by pulling on the free end of the paper which corresponds to the outer layer of the roll: in this case it is referred to as peripheral feeding of the paper.

When the user has a certain amount of paper, he can cut it by, for example, a cutting edge of the dispenser opening. For the operator of the paper dispenser, and therefore for its designer, one of the main issues in defining the characteristics of the dispenser and its roller is the minimization of paper consumption. The disadvantage of the device described above is the freedom of the user of the paper to unwind a large amount of paper sheets by pulling on the end of the strip continuously. This faculty of the user is statistically translated by a considerable waste of paper, since the user rolls out more paper than he needs.

One solution is to force the user to unwind the sheet-by-sheet paper. The prior art proposes, in the field of kitchen paper or wiping, that is to say paper which is, compared to toilet paper, thicker, more resistant to water whose leaves are more large, as well as less flexible and less soft, central-fed single-sheet dispensers.

In the latter, the paper is unwound from the center of the roll and extracted through the orifice of a nozzle, placed in the axis of the roll or at the periphery of the dispenser, the nozzle being generally of frustoconical shape and of small cross section. exit to impose the distribution sheet by sheet. We speak of central reeling of the paper, in this case sheet by sheet. An example of such a dispenser is described in the document FR 2, 761, 252 .

We know by the French patent application FR0451748 from GEORGIA PACIFIC FRANCE a sheet-fed toilet paper dispenser with a dispensing nozzle, which delivers creased sheets of paper at the outlet of the nozzle, which makes them pleasant to use, while at the same time ensuring minimum paper consumption.

Such a center-fed dispenser has a certain storage capacity. Once this capacity is exhausted, the paper is no longer available. As a result, toilet users must find an operational distributor with paper always available. There is a need to increase the availability of paper and to provide an always operational distributor.

The immediate solution to increase the size of the rolls is not satisfactory. Indeed, if during the verification of the volume of available paper, one realizes that it remains relatively little, one can replace the partially empty roll by a new roll, which results in a mess, or not replace it and wait for it to finish, which may result in a shortage if the roll is not changed in time.

In other words, a roll of large capacity can limit the number of reloads but does not limit the risk of shortage and does not increase the availability of paper.

Another immediate solution would be to provide several distributors next to each other so as to allow to have a large amount of paper to avoid a shortage while avoiding a mess.

In practice, this solution has a significant cost. Doubling the number of distributors provides no savings. In addition, the paper dispensers are generally arranged in toilets whose dimensions are limited. An increase in the number of distributors leads to a reduction in the space reserved for users in the toilets.

Another problem encountered in the arrangement of toilets is the positioning of a dispenser which has a larger dimension in one direction relative to another direction.

In order not to collide with the toilet door or the ramp provided in the toilet adapted for the disabled, it is advisable to position the largest dimension of the dispenser horizontally, vertically or inclined according to the organization space of places.

• un socle avec au moins un premier logement et un deuxième logement pour recevoir respectivement les au moins premier et deuxième rouleaux, et
• au moins une première porte et une deuxième porte montées sur le socle et agencées, en position de fermeture, pour protéger respectivement les premier et deuxième rouleaux et, en position d'ouverture, pour accéder respectivement aux premier et deuxième logements afin de les recharger en rouleaux de manière individuelle, les première et deuxième portes comportant respectivement une première et une deuxième buse de distribution des bandes des premier et deuxième rouleaux.

To this end, the invention relates to a paper roll dispenser, in particular an absorbent paper, comprising a housing in which is housed at least two rolls of a paper strip, the housing comprising:

• a base with at least a first housing and a second housing for respectively receiving the at least first and second rolls, and
• at least a first door and a second door mounted on the base and arranged, in the closed position, to respectively protect the first and second rolls and, in the open position, to respectively access the first and second housings in order to recharge them in rolls individually, the first and second doors respectively having a first and a second strip distribution nozzle of the first and second rollers.

The dispenser according to the invention advantageously allows to be continuously operational by allowing to have paper always available, one of the rollers being used as a spare roll. Thanks to the individual doors, the reloading of each of the distributor's housing is independent. This advantageously allows not to disturb the distribution of a roll that is not fully unwound during reloading of the other roll. In addition, this avoids contamination of the roll during reeling.

Furthermore, when closing the doors, it is necessary to pull the end of the sheet extracted from the nozzle while closing the door to prevent the sheet to remain between the side of the roll and the closed door. which would cause a jam during the unwinding. The dispenser according to the invention allows the maintenance agent to properly close the door and to keep the paper strip properly positioned relative to the nozzle. The ergonomic constraints are thus respected for the maintenance agent.

In the case of central reeling, when the roll is new, it has a certain rigidity that allows it to be manipulated without altering its ability to unwind. Once the roll is started, its rigidity decreases as it is unwound. If a roll that is partially started receives a shock or is displaced, it collapses on itself and can no longer be used, a central reeling of the roll is then no longer possible.

Another use of this dispenser makes it possible to provide rolls of different types in each of the housings, which makes it possible to offer a greater variety of papers for the users.

The dispenser is advantageously compact and allows the use of rolls of toilet paper whose dimensions are similar to the patent application FR0451748 .

Preferably, the doors are contiguous in the closed position. Thus, the doors do not spare space between them which prevents a liquid from reaching the rolls that are protected by the doors. In addition, the contiguous doors make it possible to form a global hood with at least two distribution nozzles.

According to another aspect of the invention, the first and second doors are connected by pivoting means to the base, which are arranged to separate the doors of the base during the opening thereof, the doors remaining close to one of them. the other in the closed position.

Preferably, the pivoting means are in the form of an oblique hinge. The term "oblique" means that the respective directions of the hinges are different. Once the dispenser is attached to a vertical wall, the hinge advantageously allows to guide the door relative to the base obliquely. When opening the door, it moves away from the other door without friction. It is the same when closing when the door is close to the base and is joined with the other door that during the total closure.

Other means may be envisaged for mounting the doors, such as slideway means with translational opening.

• une face arrière ouverte pour permettre l'introduction du rouleau dans l'enveloppe lorsque la porte est refermée,
• une face latérale vers ladite autre porte, et
• des autres faces de manière à ce que les portes, en position de fermeture, forment ensemble une enveloppe continue.

Preferably, each door is in the form of an envelope comprising:

• a rear face open to allow the introduction of the roll into the envelope when the door is closed,
• one side face towards said other door, and
• other faces so that the doors, in the closed position, together form a continuous envelope.

According to another aspect of the invention, the first and second housings respectively comprise a first and second roller support arranged to support respectively the first and second rollers when the dispenser is in the mounted position.

The dispenser can be mounted on a vertical surface in several positions (vertical, horizontal, oblique).

Advantageously, the roll holders are used to hold and support the rollers in all positions. The attachment means of the rear face of the base are provided for this purpose to allow easy fixing in all positions. They are for example provided with oblong orifice to adapt to the different positions existing on the vertical surfaces.

Preferably, the geometries and / or dimensions of each roller support are arranged to laterally cover the roller which it supports so as to protect it laterally when a door is open. Thus, when a first housing is reloaded and its first door is open, the second roller, which must not be reloaded and is protected by its second door, is accessible by its open side. The support of the second roller advantageously protects the lateral part of the second roller and advantageously replaces a "closed" side face of the second door.

More preferably, the roll supports extend orthogonally with respect to the base at the periphery of the first and second housings.

Still preferably, the roller supports are in the form of a cylinder or a cylinder portion. The roller support is recessed laterally, preferably the part which supports the roll forms an angle (α) between 180 and 360 °, preferably strictly greater than 180 ° and less than or equal to 280 °.

Advantageously, each door of the dispenser cooperates with the supports of its housing to ensure a continuous partition wall when the door of the other housing is open and thus prevent contamination of the second roller when reloading the first housing.

According to another aspect of the invention, each housing comprises a pusher plate, elastic means being mounted between the housing and the pusher plate so as to move the tray from its housing. Thus, the rollers are forced against the doors which keeps the plated rollers properly against the door and thus prevent the collapse of the rollers.

Preferably, each door comprises locking means arranged to lock the door relative to the base in the closed position.

Finally, according to one embodiment of the invention, the dispenser is a central unwinding dispenser.

According to a preferred embodiment of the invention, the dispenser is a dispenser of absorbent paper such as toilet paper.

With reference to the figure 1 the dispenser 10 of the invention is a toilet paper dispenser.

Here, the toilet paper is a paper made of cellulose wadding, for example comprising two plies, or layers, possibly interconnected by any suitable mechanical or chemical means, for example by knurling or gluing, in a manner well known to those skilled in the art. . The toilet paper is in the form of a strip which is wound into a roll 4, the latter having a central internal mandrel or not, the mandrel being removed at the time of operation of the roller. The strip has pre-cuts transverse to the unwinding direction of the strip, defining paper sheets that can be detached individually.

The distributor 10 comprises a housing 60, of elongate shape, for receiving at least two rollers 4, 4 ', which are cylindrical in shape. The housing 60 is arranged so that the rollers 4, 4 'do not rotate on their axis during unwinding.

In this example, the housing is formed of a single piece forming a global housing. It goes without saying that the housing could be formed of at least two individual housings mounted together for example by means of clips.

With reference to Figures 1 to 4 , the housing 60 comprises a base 5 in which are housed the rollers 4, 4 '. The rollers 4, 4 'are covered by a cover formed by two doors 1, 1' allowing the individual refilling of each of the rollers 4, 4 'in the distributor 10. The term "base" is understood to mean a single base or the assembly of several elementary bases, for example by means of clips to ultimately form said base.

Subsequently, the terms "left" and "right" are defined in relation to the figure 4 on which the distributor 10 is divided by the plane (P) the parts of the distributor to the left of the plane of (P) being designated "left parts" while those to the right of the plane of (P) are designated "right parts".

The dispenser 10 will now be described in detail.

Distributor base (5)

With reference to the figure 5 , 9 and 10 , the base 5 is in the form of an elongated element in which are formed two housing 51, 51 'of receiving rollers 4, 4 ': a housing on the right 51 and a housing on the left 51'.

The housings 51, 51 'are formed in the thickness of the base. The housings 51, 51 'are here circular to respectively accommodate rolls of toilet paper 4, 4' of tubular form.

Each housing 51, 51 'comprises through openings 54 which are arranged to allow the attachment of the base 5 to a vertical wall. In this example, each housing 51, 51 'comprises a plurality of through openings 54, including a central, being in the form of a longitudinal groove having in its middle a circular opening. In a known manner, this makes it possible to manually fix the distributor 10 to a wall in which screws are fastened.

The plurality of apertures 54 are designed so that the dispenser 10 can be mounted in a horizontal position (if the large dimension of the dispenser is horizontal), in a vertical position (if the large dimension of the dispenser is vertical) and in an oblique position (if the large dimension of the dispenser is oblique).

Subsequently, the distributor 10 is described mounted in a horizontal position, but it goes without saying that the distributor 10 could also be mounted in a vertical or oblique position.

Protective doors (1, 1 ')

Referring now to Figures 3 and 4 , the rollers on the right 4 and left 4 'are respectively protected by a door on the right 1 and a door on the left 1' which are pivotally mounted relative to the base 5 via a hinge on the right 2 and a hinge located on the left 2 '.

The doors 1, 1 'each comprise a nozzle 3, 3' for dispensing the strips of toilet paper rollers 4, 4 '.

The toilet paper is unwound from the center of the roll 4, 4 'and extracted through the orifice of the nozzle 3, 3'. The nozzle 3, 3 'is generally frustoconical in shape and of small output section to impose a sheet-to-sheet distribution.

In the closed position, the doors 1, 1 'protect the rollers 4, 4' against possible external aggressions so as to ensure that the toilet paper remains hygienic. For this purpose, the doors 1, 1 'are joined in the closed position so as to form a global cover for the distributor 10. In this example, each door 1, 1' is in the form of a partially cylindrical envelope, comprising a rear face open to allow the introduction of the roll 4, 4 'into the envelope when the door 1, is closed, a side recessed or semi-recessed towards said other door 1, 1' and other faces so that the doors 1, 1 ', in the closed position, together have a continuous envelope. In other words, the combination of the two doors 1, 1 'in the closed position advantageously performs the same function as a single overall cover. In other embodiments, the side face may also be full.

In the open position, the doors 1, 1 'allow access to the housing 51, 51' in order to reload rollers 4, 4 'individually. This allows to individually recharge a housing 51, 51 'by opening a door 1, 1' while leaving the other door 1 '1 in the closed position so that it protects the roll 4', 4 in progress use.

In this example, with reference to figures 2 and 6 the hinges 2, 2 'are oblique hinges; that is, the direction of the axis of the right hinge 2 is different from the direction of the axis of the left hinge 2 '. In addition, the axes of the hinges 2, 2 'do not respectively extend parallel to the direction in which the distributor 10 extends. This advantageously makes it possible to pivot the door 1, 1' obliquely with respect to the base 5.

In other words, again for a distributor 10 mounted horizontally, when opening a door 1, 1 'it moves in an oblique direction which comprises a vertical component but also a horizontal component so as to deviate from the center of the distributor 10, ie of a plane (P), the plane (P) corresponding to the side faces of the doors (1, 1 '). In others terms, between its closed position and its open position, the door 1, 1 'deviates from the plane of (P) which prevents the doors 1, the contact with it during the opening or closing one of the two doors. Preferably, the hinges 2, 2 'are in the lower part of the distributor 10 so that the doors 1, 1' open essentially from top to bottom.

The doors 1, 1 'furthermore comprise each of the closing locking means 7, 7' which are presented with reference to the Figures 7 and 8 in the form of a lock closed by a key. This advantageously avoids any theft of roll of toilet paper. The closing locking means 7, 7 'are here located in the upper part of the distributor 10 mounted horizontally.

Roll holders (6, 6 ')

Still referring to the figure 5 for a horizontally mounted distributor 10, each housing 51, 51 'comprises at its periphery a roll support 6, 6' in the form of a cylindrical tubular portion extending perpendicular to the base 5. The cylindrical tubular portion is laterally recessed so as to allow a longitudinal and lateral introduction of a roll 4, 4 'into a housing 51, 51', the portion protruding from the base, which supports the roll forms an angle α as shown in FIG. figure 5 .

In the horizontal use position, when the distributor 10 is mounted on a vertical wall, the angle α of the support 6, 6 'is oriented upwards so as to allow easy insertion of the roll 4, 4' from the top to down, in a vertical direction. The support 6, 6 'fulfills a function of supporting the mass of the roll but also a protective function of the web of the roll 4, 4'. This last function will be explained later.

In this example, the angle α of the support 6, 6 'is about 240 ° but it goes without saying that any angle between 180 ° and 360 ° could also be suitable to fulfill this dual function. Indeed, with such a degree of opening, the support 6, 6 'still fulfills its function of supporting the rollers 4, 4' when the distributor 10 is in a vertical or oblique position.

Referring now to Figures 9 and 10 each housing 51, 51 'further comprises a pusher plate 52, of circular shape, for receiving on its front face a roller 4, 4'. Elastic means, here springs 53, are mounted between the rear face of the pusher plate 52 and the front face of the housing 51 to press the roller against the door 1 in the closed position. With reference to figures 5 , 9 and 10 , each housing 51, 51 'comprises, on its front face, tubes 55, vertically projecting, which are arranged to receive the springs 53, 53' in their internal volume.

The presence of a plurality of springs 53, 53 'in the same housing 51, 51' advantageously makes it possible to balance the forward thrust exerted by the pusher plate 52, 52 'and thus to allow a homogeneous contact between the roller 4, 4 'and its door 1, 1'.

Furthermore, the pusher plate 52, 52 'is retained in its housing 51, 51' by stops which limit the travel of the pusher plate 52, 52 'and thus prevent the pusher plate 52, 52' from separating from its housing. 51, 51 '.

According to another embodiment, the support of the roller may be an integral or integral part of the base.

According to yet another embodiment, the support may be formed of a plurality of bearing zones or surfaces holding the roller in place and providing the support function in all directions. The materials of this support will be appropriately chosen to fulfill this function.

An implementation of the invention will now be presented.

Use of the distributor

Once attached to a vertical wall in a horizontal mounting position, the rollers 4, 4 'extend in their housing 51 orthogonal to the base 5, the mass of the rollers 4, 4' being supported by the supports 6, 6 'which extend under the rollers 4, 4 '. The supports 6, 6 'advantageously form cradles in which the rollers 4, 4' are received.

The rollers 4, 4 'are protected by the doors 1, 1' in the closed position which form a global cover for the distributor 10, thus protecting them against external attacks (shocks, liquid, etc.). One end of the toilet paper strip of each roll 4, 4 'protrudes via the dispensing nozzle 3, 3' of each of the doors 1, 1 'as shown in FIG. figure 1 . Thus, a user can easily pull the end of the strip to obtain a sheet of paper.

In addition to its compactness, the distributor 10 has a reserve roller 4 'or 4 which can cope with any shortage and / or limit the number of reloading. Furthermore, the rollers 4, 4 'are reloaded independently of one another, which makes it possible to completely use a roll 4, 4' before replacing it, the spare roll 4 ', 4 making it possible to ensure the transition.

The toilet paper strip may be of different types in each of the housings (normal paper and allergy-resistant paper for example), which allows a greater flexibility of use of the dispenser 10. Preferably, the dispensing is done sheet by sheet which leads to a decrease in paper consumption by users.

Furthermore, the doors 1, 1 'are locked to the base 5 by the locking means 7, 7' to prevent theft of rollers 4, 4 '.

Reloading the distributor

For example, to reload the housing on the right 51 of the distributor 10, the user in charge of maintenance must first unlock the door on the right side 1 so as to allow the pivoting of the door on the right 1 relative to the base 5.

Following its opening, the right-hand door 1 moves in an oblique downward direction to come to rest under the dispenser 10 as shown in FIG. figure 3 . Once opened, the door on the right 1 is in a stable position under the dispenser, the housing on the right 51 being then accessible for reloading.

Although the support on the right 6 is not represented on the figure 3 a new roll 4 is disposed in the support on the right 6 of the dispenser 10, the rear end of the roller located on the right 4 being in abutment on the plate located on the right 52 of the housing on the right 51. After passing the end of the strip of the roll 4 in the dispensing nozzle 3, the door on the right 1 by turning it in the opposite direction and simultaneously pulling the paper strip extracted through the orifice of the nozzle. Closing the door on the right 1 causes pressure on the roller on the right 4. In the closed position of the door on the right 1, the roller on the right 4 is firmly held between the door on the right 1 and the tray located on the right 52 which avoids any sagging of the roller on the right 4.

With reference to Figures 7 and 8 it is noted that the refilling of the dispenser 10 is particularly hygienic. Indeed, although the right-hand door 1 is recessed laterally in the closed position, the support located on the left 6 associated with the side wall of the right-hand door 1 comes to protect laterally the roll on the right 4 during the reloading of the door. roll on the left 4 '.

In other words, the angle α of the support 6, 6 'is advantageously calibrated to allow, on the one hand, an easy introduction of a new roll (need for a small angle) and, on the other hand, a support and effective protection of the roll started when a new roll is inserted (need a wide angle).

The invention has been presented here with a dispenser comprising two rollers but it goes without saying that the dispenser could comprise more than two rollers aligned or staggered in the dispenser.
