Definitions

  • the invention relates to a roll of a strip of toilet paper which can be accommodated in a dispenser.
  • toilet paper dispensers In public places, in particular, toilet paper dispensers generally include a housing, in which is mounted a roll of a strip of paper which is unwound by a dispensing orifice.
  • the paper strip has pre-cuts transverse to the direction of its unwinding, defining rectangular sheets which can be detached individually.
  • the toilet paper is a paper of cellulose wadding, flexible and soft on the surface, comprising one or more plies whose grammage is usually between 14 g / m 2 and 30 g / m 2 approximately.
  • the most widespread dispensers include an opening, or window, at least the width of the toilet paper, arranged in the low position on the dispenser, through which the paper is unwound.
  • the unwinding is done by pulling on the free end of the paper which corresponds to the outer layer of the roll: in this case we speak of peripheral unwinding of the paper.
  • the user has a certain amount of paper, he can cut it thanks, for example, to a cutting edge of the dispenser opening.
  • the disadvantage of the device described above is the freedom of the paper user to unwind a large quantity of sheets of paper by pulling the end of the strip continuously. This ability of the user translates statistically into a considerable waste of paper, since the user unwinds more paper than he needs.
  • the prior art proposes, in the field of kitchen or wiping paper, that is to say paper which is, by comparison with toilet paper, thicker, the sheets of which are larger, as well as less flexible and less soft, sheet feeders with central unwinding.
  • 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 on the periphery of the dispenser, the nozzle being generally of frustoconical shape and of small cross section. output to impose sheet-by-sheet distribution.
  • An example of such a distributor is described in the document FR 2, 761, 252 .
  • the sheet-by-sheet distribution is conditioned by the ratio of the force necessary to extract the sheet through the nozzle and the force necessary to tear the pins holding between them two adjacent sheets of the strip of paper; the section of the nozzle outlet orifice influences this ratio: the smaller it is, the greater the probability of cutting a sheet on each extraction.
  • a dispenser has been proposed with a nozzle having an orifice very small diameter outlet, to ensure sheet-by-sheet distribution.
  • the disadvantage of such a nozzle was, first of all, the difficulty of the initial placement of the paper in the nozzle, then the fact that at the exit of such a nozzle, the toilet paper was completely wrinkled and was in the form of a string unpleasant for the user, who had to unfold the outgoing sheet in order to use it.
  • the invention relates to a roll of a strip of toilet paper comprising at least the features of claim 1.
  • This description also provides a sheet-by-sheet toilet paper dispenser, with a dispensing nozzle, which delivers slightly crumpled sheets of paper. at the outlet of the nozzle, which makes them pleasant to use, while also ensuring minimum consumption of paper.
  • a toilet paper dispenser comprising a housing in which is housed a roll of a strip of paper, which comprises pre-cuts transverse to the strip defining rectangular sheets of paper, the width of which is transverse and the length longitudinal, the casing comprising a nozzle with a dispensing orifice, through which the strip of paper is unwound, dispenser characterized in that the nozzle and the paper roll are arranged so that the sheets of paper are unwound one by one and come out with reduced wrinkling at the outlet of the nozzle, the width of a sheet is between 125 mm and 180 mm and the ratio of the width of a sheet to its length is between 0.45 and 1, preferably between 0.5 and 0.65, the paper being optimally and pleasantly consumed.
  • the Applicant has discovered that by proposing a new proportion between the width and the length of the sheets of paper, it is possible not only to ensure sheet-by-sheet distribution of the paper, but also to allow the sheet of paper to smooth out by itself at the nozzle outlet when you pull on it, while maintaining a standard sheet surface and therefore avoiding overconsumption of paper.
  • the description also relates to a toilet paper dispenser, comprising a housing arranged to receive a roll of a strip of paper, the width of which is between 125 mm and 180 mm, the housing comprising a nozzle with a paper distribution orifice, the nozzle being of frustoconical shape, its orifice of small diameter being the dispensing orifice, situated outside the nozzle relative to the housing, the diameter of the dispensing orifice of the nozzle being between 6 and 8 mm , preferably equal to 7 mm.
  • the dispenser 1 is a toilet paper dispenser.
  • the toilet paper is here a paper made of cellulose wadding, comprising two folds, or layers, connected together by any appropriate 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 2 which is wound in a roll 3, the latter having no central internal mandrel, the paper being initially wound so that a strip end 12 protrudes from the part center of the roller 3 before it can be unwound.
  • the strip 2 has pre-cuts 4, transverse to the direction of unwinding of the strip 2, defining sheets of paper 5 which can be detached individually. These sheets of paper 5 are rectangular; they are defined by a transverse width "l” and a longitudinal length "L".
  • transverse or longitudinal reference will always be made to transverse and longitudinal with respect to the strip 2, in its direction of unwinding.
  • the dispenser 1 comprises a housing 6, of cylindrical shape, for receiving the roller 3, also of cylindrical shape.
  • the housing 6 is arranged so that the roller 3 does not rotate on its axis during its unwinding.
  • the box 6 comprises means for hooking, not shown, to a support, here to a wall 7 of the room in which the distributor 1 is to be placed, means arranged so that once the distributor is hooked, the axes of the housing 6 and the roller 3 are perpendicular to the wall 7.
  • the housing 6 here comprises, on its face opposite the wall 7, a transparent portion 8, which makes it possible to see, by transparency, the roller 3 and the strip 2 at the inside of housing 6.
  • the housing 6 comprises, at the periphery, at an edge on the side opposite the wall, a dispensing nozzle 9.
  • This nozzle 9 is here of frustoconical shape, its orifice of smaller diameter being the outlet orifice, or dispensing orifice 10, located on the outside of the nozzle 9 relative to the housing 6.
  • the free end of the strip of toilet paper 12, starting from the center of the roller 3, is inserted into the nozzle 9 so as to project therefrom through its dispensing orifice 10.
  • the nozzle 9 being here located at the periphery of the housing 6, with its axis perpendicular to the axes of the housing 6 and of the roller 3, there is an angle reference of the strip 2 between the axis of the roller 3 and the axis of the nozzle 9. This angle reference takes place here naturally, without adding any additional structural element. However, there could be provided an angle return member such as a pulley or an axis.
  • the strip 2 When a user pulls on the end 12 of the strip projecting from the nozzle 9, the strip 2 unwinds from its center.
  • the diameter of the dispensing orifice 10 of the nozzle 9 and the sheets 5 are arranged, as developed below with their dimensions, so that the dispensing takes place sheet by sheet.
  • the force of extraction of the paper from the nozzle 9, which depends in particular on the friction of the strip of toilet paper 2 on the wall of the dispensing orifice 10 of the nozzle 9, must be greater than the tear force of the tenons holding two adjacent sheets 5 of the strip 2, which depends in particular on the resistance of the toilet paper and the rate perforation of the precuts 4, equal to the ratio of the sum of the transverse dimensions of the tenons of a sheet on the width of the strip 2.
  • This ratio of the extraction force to the tearing force must in particular be sufficient to compensate for the variations in angle between the pre-cuts 4 of the paper and the axis of the dispensing orifice 10 of the nozzle 9, an angle which influences tearing of the paper, variations linked to the fact that the paper does not always appear at the same angle, in particular according to the quantity of paper which has already been unwound.
  • the applicant wanted to increase the width "I" of the sheets 5 as well as the diameter of the dispensing orifice 10 of the nozzle 9, in order to facilitate the unfolding of the sheets 5 at the outlet nozzle 9.
  • the Applicant had further considered that the sheets 5 must maintain an area equivalent to that of the sheets of the prior art, so as not to cause overconsumption of paper but still to ensure the wiping function sheets 5.
  • the sheets of the prior art are 98 mm wide and 350 mm long, therefore having an area of 34,300 mm 2 .
  • the Applicant has therefore modified the proportions between width "I" and length "L" of the sheets, but while respecting an equivalent sheet area, to within a percentage, which is to be defined by the manufacturer of the dispenser 1.
  • the Applicant has carried out a series of tests, including in particular tests for calculating the percentage of success of sheet feed, sheet behavioral tests for users, tests well known to those skilled in the art. It deduced therefrom a range of preferred parameters, in addition to the I / L ratio, making it possible to better fulfill all of the objectives of the invention, namely a sheet-by-sheet unwinding of the paper, a smoothing of the sheets at the outlet of nozzle and paper consumption reduced compared to distributors of the prior art. These additional preferred parameters will be presented below.
  • the table below represents certain data from a series of tests which were carried out, on the one hand on a roller of the prior art, on the other hand on a series of rollers 3 according to the invention, the sheets of which include a ratio "I / L" of between 0.45 and 1.
  • the tests were carried out with paper with two plies of grammage 16 g / m 2 for each, with a nozzle 9 whose dispensing orifice 10 has a 7 mm diameter.
  • the embodiment of the figure 1 with the axis of the housing 6 and the roller 3 perpendicular to the wall 7, in conjunction with the sizing of the toilet paper of the invention is advantageous, since the space requirement is reduced in the direction perpendicular to the wall of the toilet 7. In fact , this size is here directly dependent on the width "I" of the sheets of paper 5, which is fixed, as we will see, between 125 and 180 mm. This space is acceptable in a room and is thus limited.
  • a distributor 1 comprising a housing 6 and a nozzle 9, thus ensuring a protective function of the roller 3 for hygiene and theft prevention.
  • the dispensing is done sheet by sheet and the replacement and the positioning of the roller 3 are easy to carry out, in particular with a dispensing orifice 10 of nozzle 9 sufficiently large to reduce wrinkling of the sheets.
  • the format of the sheets 5, combined with the sheet-by-sheet distribution, results in a reduction in the consumption of paper by the users.
  • the size is limited by the width of the strip 2 and allows an increase in the length of the strip 2, increasing the autonomy of the roller 3, all the more so since the latter comprises a greater number of sheets 5 per unit of length.
  • the Applicant has carried out tests to size the paper roll 3 suitable for the dispenser 1 in a preferred embodiment of the invention, here in the context of a central unwinding with the nozzle 9 in the axis of the roll 3, of which the results are reported in the table below.
  • the Applicant has carried out tests for three different perforation rates of the precuts, 14% , 16% and 20%, each for two sheet formats ((254x136) mm 2 and (235x146) mm 2 ) and belonging to the parameter ranges of the invention.
  • the nozzle 9 can, as described here, extend around the periphery of the housing 6, but also in the axis of the roller 3, which could in this case be horizontal or vertical, whatever whatever the embodiment chosen. Furthermore, it could possibly be provided a mandrel for supporting the roller 3 in the housing 6. Finally, the nozzle 9 is not necessarily frustoconical; it can be any calibrated dispensing orifice.
