Description

The present invention relates to a dispenser of individual sheets of paper.

The invention relates in particular to a distributor allowing the user to take one or more multiple sheets by reeling from the center of a product in roll, without mandrel or central core, consisting of several successive sheets forming a coiled band of which a free end projects towards the outside of the roll from the center of the roll.

Such a distributor is used in particular to obtain multipurpose tissue paper sheets made from cotton wool of cellulose.

The paper is in the form of a band rolled from which to cut the leaves successive.

For this purpose, a first technique consists in the outlet of the distributor means that partially block the unwinding of the belt, under the effect of the tensile force it is applied by the user, by means whose edge lower is sharp or sawtooth-shaped, so to form leaves by tearing and / or cutting from a continuous band.

According to another technique, the roll tape is pre-cut, that is to say that it comprises cutouts regular partial corresponding to consecutive sheets generally of the same length, and the dispenser comprises, here too, at its lower end means through which pass the pre-cut paper tape that squeeze it for allow the user to separate the sheet he has extracted from the distributor, of the following sheet, exerting an effort abrupt additional traction to separate it according to the pre-cut line.

• un boítier de distributeur comportant une première partie fixe et une seconde partie mobile montée articulée par rapport à la partie fixe entre une position ouverte de rechargement du distributeur et une position fermée dans laquelle elle délimite, avec la première partie, un logement supérieur de stockage en position verticale du rouleau à dévider ;
• une plaque inférieure, portée par la partie fixe du boítier, qui supporte verticalement une extrémité axiale inférieure du rouleau et qui comporte un trou de passage de la bande ;
• et une buse fixe de distribution qui est disposée en dessous de la plaque support, qui délimite un passage, de forme générale tronconique, convergent vers le bas, dont l'ouverture supérieure d'entrée est sensiblement dans le prolongement du trou de la plaque support, pour guider la bande vers son ouverture inférieure de sortie de diamètre réduit, et qui comporte une découpe, en forme générale de fente, d'orientation générale verticale qui s'étend entre les ouvertures supérieures d'entrée et inférieure de sortie pour faciliter l'introduction de l'extrémité libre de la bande d'un rouleau dans le passage de la buse de distribution,

   et dont la largeur de la découpe au voisinage de l'ouverture supérieure est nettement supérieure à sa largeur au droit de l'ouverture inférieure de sortie dans laquelle elle débouche verticalement vers le bas, de manière à permettre l'introduction de ladite extrémité libre de la bande verticalement de bas en haut à travers la découpe, puis radialement vers l'axe de la buse de distribution.For this purpose, it has already been proposed a distributor of the type comprising:

• a distributor housing comprising a first fixed portion and a second movable portion hinged relative to the fixed portion between an open position of refilling the dispenser and a closed position in which it delimits, with the first part, an upper storage housing; vertical position of the unwinding roller;
• a lower plate, carried by the fixed part of the housing, which vertically supports a lower axial end of the roller and which comprises a passage hole of the strip;
• and a fixed distribution nozzle which is arranged below the support plate, which delimits a generally frustoconical passage converging downwards, the upper inlet opening of which is substantially in the extension of the hole of the support plate for guiding the strip towards its lower outlet opening of reduced diameter, and which has a generally slot-shaped cutout of generally vertical orientation which extends between the upper inlet and the lower outlet openings to facilitate introducing the free end of the web of a roll into the passage of the dispensing nozzle,

and whose width of the cutout in the vicinity of the upper opening is substantially greater than its width in line with the lower outlet opening into which it opens vertically downwards, so as to allow the introduction of said free end of the strip vertically from bottom to top through the cutout, then radially towards the axis of the dispensing nozzle.

A first example of such a distributor is described and represented in EP-A-0.740.921 in which the closing element of the cutout of the dispensing nozzle is made in one piece at the bottom of the second moving part of the housing and in which the cut is a narrow vertical slot with parallel edges that opens vertically up and down in openings upper and lower exit of the formed passage in the body of the dispensing nozzle.

Such a design has many disadvantages.

First, the slot is narrow and the introduction of the free end section of the tape of a new roll, or of a partially unwound roll, is difficult to achieve without damage the tape, as the slot is narrow and insofar as it is necessary to maintain the second mobile part of the housing in the high position.

In addition, when closing the housing by tilting vertically downwards from its second moving part, the closure of the cutout by the closure element integrated in the mobile part of the housing is done "blind", that is to say there is a significant risk that the person responsible for roll replacement jams the tape into the slot by means of the closure element.

Moreover, in use, we find that the a strip of paper that passes through the passage of the nozzle, rubs continuously against the part of the inner wall of the passage convergent which is cut out and completed by the element of closure, that is to say that the band rubs against a wall that is not perfectly smooth and continues with a risk important, if the adjustment of the two parts is not perfect, to damage the paper tape.

Another example of such a distributor according to the state of the technique is described and represented in the patent application American number USSN08 / 732,014 filed October 16 1996 (= EP 0836 825A).

The design proposed in this document is broadly similar to that described and analyzed previously, with the exception that the axis of articulation of the second moving part of the housing is a vertical axis.

This design has most of the disadvantages previously mentioned with respect to that described and represented in EP-A-0.740.921.

In order to overcome these disadvantages, the invention proposes a distributor of the type mentioned previously, characterized in that the cutout is formed in a portion of the passage which is located towards a vertical background back of the party fixed housing by which the latter is attached to a wall or on a support, so that, in use, the section of the band passing vertically through the dispensing nozzle cooperates with an uncut portion of the inner wall of the passage.

In the description that follows, we will use the terms vertical, horizontal, upper, lower, front, back, etc. in reference to figures to facilitate understanding of the description, but not limited to the invention.

The distributor 10 according to the invention, represented particularly in Figure 1, is essentially constituted by a housing 12, by an intermediate part 14 comprising the nozzle of distribution and which is associated with a closure element 16 of its cutting, and by a plate 18 which is intended for support a roll 20.

The distributor 10 has the function of enabling the progressive unwinding of the roll 20 which is here a roll constituted by a band 22 of cellulose wadding which is wrapped around a general vertical axis A1.

The center of the roll does not have a mandrel or central mandrel, ie it is constituted by a hole central vertical orientation through which fate, here vertically downward, the inner free end 24 of the band 22.

The roller 20 is delimited by a lateral surface external cylindrical 26 and two transverse faces end including a horizontal lower transverse face 28 generally annular shape which is visible in Figure 1.

The housing 12 is in the form of two parts made by plastic molding.

A first fixed part 30 is constituted for the essential by a rear vertical plate 32 and a plate lower horizontal 34 constituting a horizontal bottom which is centrally pierced by a substantially circular hole large size 36.

The fixed part 30 allows fixing, by means not represented, of the housing 12 on a wall or on a column, by through the rear vertical plate 32, and the fixed part 30 also has a lower portion of the side wall 35 in low cylinder arc.

The housing 12 also has a second moving part 38 forming a closure cover which is constituted for essentially by a U-shaped side wall 40 and a wall front transverse, vertical orientation in the closed position of cover 42.

The mobile part forming a cover 38 is hingedly mounted on the fixed part 12 about a horizontal articulation axis A2 which is arranged in the vicinity of the bottom 34 of the fixed part 12 and in the vicinity of the horizontal lower edges 44 of the wall lateral 40.

As can be seen in Figure 1, in the open position hood 38, it extends vertically entirely in below the fixed part 12 by completely releasing the part top of the housing without cluttering the environment of this latest.

It is of course provided means, not shown, to lock the cover 38 in the upper closed position in which its side wall 40 and its front face 42 cooperate with the rear transverse wall 32 and the bottom 34 to delimit a closed enclosure in which in particular is received the roll 20.

The plate 18 has a peripheral shape contour complementary to that of the horizontal bottom 34 of the housing 12 and it is dimensioned so that it can be received in the housing 12 with the outer peripheral portion of its face lower 46 in vertical support against the upper face 48 of the bottom 34, the two faces 46 and 48 being in mutual support by gravity when the support plate is in place in the bottom housing 12.

The support plate 18 has an upper face smooth 50 on which the roller 20 is supported by its face 28 and it is centrally pierced, ie it has a central hole of substantially circular contour 52 for the passage, through the hole 52, of the free end 24 of the strip 22 of the roll 20.

The dispensing nozzle 14 is a molded part in plastic material of general shape of revolution around the vertical axis A1.

It has a cylindrical annular skirt peripheral 54 having a collar-shaped upper edge horizontal 56 here comprises three radial pins 58 which belong to fastening means of the bayonet type of the nozzle 14 under the support plate 18, these means further comprising complementary notches 60 formed under the lower face 46 of the plate 18.

Thanks to their assembly by the means of the type to bayonet, the body of the nozzle 14 and the plate 18 constitute a subset, illustrated in particular in Figures 2 and 3, which is set up in the housing 12, the dispensing nozzle 14 then extending vertically down through the cutout 36 beyond the bottom 34 of the housing 12.

The nozzle 14 comprises, in a generally known manner, a central passage 62 of frustoconical general shape and convergent vertical orientation downward.

More precisely, the passage 62 is constituted by the internal wall 64 of a central portion in the form of a bowl frustoconical 66 which is connected to the skirt 54 by a ferrule of connection 68.

The passage 62 is delimited at its upper end by a circular upper opening constituted by an edge 70 and, at its lower end, through a lower opening output 72 constituted by the cylindrical wall of a section lower free end 74 of cylindrical shape of the bowl 66.

According to a known general arrangement, the diameter of the lower outlet opening 72 is significantly smaller than the large diameter of the upper entrance opening 70 of way that the band 24 which passes through the passage 62 is gradually tightened by the concave frustoconical wall convergent 64 so that the entire band is tight radially towards the axis A1 at the level of the lower opening 72.

According to the invention, the internal concave wall 64 of the passage 62 is not complete, that is to say that it comprises a cutout 80 in the general shape of a slot.

According to one aspect of the invention, cutting or slot 80 does not have parallel edges, ie it is delimited by two opposite edges 82 which are flaring vertically from bottom to top and radially from the inside towards outside.

Thus, whether in plan view along the axis A1, or in side view along the direction "D" of Figure 6, the projection of the cutout 80 delimited by the edges 82 is in profile substantially triangular.

Thus, the circumferential extension or width L1 of the slot 80 separating its two opposite edges 82 at the level of the upper opening 70 is clearly greater than its width L2 at the lower end of the slot 80, that is to say at the level of the lower opening 72.

As can be seen in the figures, the slot or cutout 80 is open vertically downward.

The triangle conformation and the dimensioning of the cutting 80 are such that it is possible to pass the band 24, without tightening or compressing it radially, through the cutting 80, vertically up and down, then introduce it in the passage 62, and in particular in the lower opening 72 then introducing it radially towards the A1 axis in the cut.

Due to the design according to the invention, it is possible to set up the roll 20 on the support plate 18 and to close the housing 12 and then pull through the cutout 80, the band 24 to pass vertically from low to high in the cut and introduce it into the passage 62, and this from the underside of the housing 12 through which, thanks at the cut-out 36, extends vertically downwards the nozzle of distribution 14.

According to a feature of the invention, the cutout 82 is oriented in a perpendicular vertical plane to the plane of the back plate 32 of the housing 12, that is to say that the cutout 80 is formed in the rear portion of the passage 62 turned towards the wall.

In use, when a consumer pulls the free end 24 of the strip 22 of the roll 20 which passes to through the passage 62, he does it forward, that is towards him, or slightly laterally but never to the rear. So, the band 24 is always in frictional contact with the wall internal concave concave 64 of the distribution nozzle 14, that is to say with a continuous surface without cutting, while that the cut part is opposite to the back.

Thus, throughout the traction, the fabric or paper 24 is in contact with a perfectly smooth surface that is not likely to damage it.

According to another aspect of the invention, it is provided a closure element 16 to complete the passage 62 of the cut in the position of use.

The closure element 16 is an element attached to the dispensing nozzle 14 which is made in the form of a molded plastic part of overall shape complementary to that of the nozzle 14.

The closing piece 16 of the blank 80 is mounted articulated with respect to the body of the dispensing nozzle 14 around a horizontal axis of articulation A3 which is parallel to the vertical bottom plane 32 of the housing 12, that is to say perpendicular to the average vertical plane of the cutout 80.

As can be seen in the figures, the cutout 80, in addition to its insertion slot function formed in the wall 64 of passage 62, is extended by cutting formed in the skirt 54 and the ferrule 68 which are cut by a recess of vertical orientation with edges parallels 90 and 92.

In order to impart sufficient rigidity to the body of the nozzle 14, the edges 90 of the cutout are interconnected by an upper cross member 94 which extends in the same plane as the edge 56.

The cross member 94 has at its lower part a half-cylinder hollow, open vertically upwards 96 constituting a housing for a horizontal rod 98 belonging to the closure element 16 constituting the means of joints of the latter, relative to the nozzle 14, about the axis A3.

More specifically, the housing 96 is constituted by two half-housings arranged laterally in opposite each receives a lateral end of the rod 98 forming two hinge pins.

The closure element 16 of the cutout 80 comprises an active main portion 100 of complementary profile of that of the bowl 66 which is delimited laterally by two opposite side edges 102 complementary edges 82 of the cutout 80 so that, in the high position of use, represented in FIGS. 2, 3 and 5, this active portion 100 is the complement of the bowl 66 to reconstitute a passage 62 in the form of a piece or bowl of revolution 66 complete, and this in order to avoid any escape accidental band 24 out of the passage 62 by cutting 80.

At its lower free end 104 of small width, the main portion 100 has a locking finger 106 and positioning which, in the high position of use, is received in two semi-cylindrical complementary dwellings 108 formed in the underside of the bowl 66 in the vicinity of the cylindrical portion 74 (see Figures 2 and 4).

For its connection to its articulation rod 98, the portion 100 of the closure member 16 is extended by two sections of ferrule 108 and a cylindrical skirt section 110 which are respectively complementary to ferrules 68 of the skirt 54 of the body of the nozzle 14.

A reinforcing rib 112, which extends in a plane vertical, connects the active portion 100 to the ferrule section immediately adjacent which has at its end superior one finger 114 automatic locking of the closure member 16 which, in use position and as can be seen in particular in Figure 5, is received in a complementary housing 116 formed by a bucket 118 made come from material by molding with the support plate 18.

The rib 112 also has an ergonomic shape for facilitate the closure of the element 16.

The locking finger 114 in the shape of a beak lock is chamfered so that it comes to lock automatically when closing of the closure element 16, that is to say when one makes rotate it clockwise from the position it occupies in Figure 6 to the position he occupies in the figure 5.

To access the locking means constituted by the spout 114, to allow the tilting, in the direction anti-clockwise around its axis A3 by considering FIG. the closure member 16, the hole 52 substantially circular support plate 18 has, towards the rear, a clearance 120 which, after opening the housing 12, to clear the notch 114 to cause the opening of the element closing 16 which rotates automatically by gravity around of the A3 axis.

This automatic pivoting is obtained because the axis A3 is shifted radially outward while the main mass, and therefore its center of gravity, is offbeat radially inward towards the axis A1.

Closing and automatic locking of the element 16 can be performed from outside the closed housing, ie below the latter while having control Visualization of the correct position of the free end of the band 24 in the passage 22 before the closure of the element and during closing maneuver, ie without risk of wedge the band 24 between the cutout 80 and the part active functional element 100 of the closure element 16.

The design in the form of a subset of the plate 18 and the nozzle 14 which carries its closure element articulated 16, allows to use the same housing 12 with the cutout 36 in its horizontal bottom 34 for another type of distributor, ie for example by replacing the subset 14-18 by an element comprising a passage of output converge vertically downward with means cutting the sheet at the periphery of the lower opening output of this passage, for example provided with saw teeth.
