Definitions

  • the present invention relates to the field of articles for smokers and particularly cigarettes.
  • the present invention relates to the field of filters for cigarettes, in particular filters for rolling cigarettes.
  • a first type of filter is composed of cylindrical blocks of foam or cellulose. These filters for cigarettes make it possible to filter certain substances contained in tobacco, and thus reduce the impact of tar and nicotine, as well as to soften the smoke.
  • a second type of coarser filter for cigarettes is also known, made by rolling up a strip of cardboard, which are those described below and those concerned by the invention.
  • pre-rolled filters there are also ready-to-use pre-rolled filters, as there are prefabricated tubes, asymmetrical or not, comprising this same type of pre-rolled filters.
  • cardboard filters allows the user of rolling papers to position a filter at the end of the cigarette in order to prevent the tobacco from coming out of the cigarette and going into the mouth. It also allows you to smoke all of the tobacco in the cigarette without burning yourself.
  • the invention aims to obtain a filter and/or a cigarette provided with this filter, which overcome the drawbacks of the filters of the state of the art.
  • a first object of the invention is a cardboard filter for cigarettes, formed by folding, rolling up and gluing a strip of cardboard, characterized in that the strip of cardboard is folded to form a central part having a series of lobes equidistributed angularly around a central axis of the filter and a peripheral part surrounding the central part, the lobes and the peripheral part delimiting gas passage channels around the central axis.
  • the filter has a better filtering capacity thanks to the regularity of the sections of the gas passage channels between the plies of the cardboard strip in the filter.
  • This regularity of the channels makes it possible to have channels of smaller and more numerous sections.
  • the lobes formed by folds form numerous internal support points, regularly distributed around the axis, for the peripheral part, which improves rigidity.
  • the geometry of the filter is more regular and improves filtration, rigidity of the filter and its aesthetics.
  • the folding, winding and gluing of the cardboard strip to manufacture the filter are carried out by a manufacturing process in an automated manner by a machine.
  • the large number of folded sections of the cardboard strip in the central part and their length contribute to a better retention of the tobacco strands and the ingredients to be smoked.
  • the gas passage channels are equally distributed angularly around the central axis of the filter.
  • the lobes have at least one outer part being in contact against the peripheral part.
  • the filter comprises at least a first lobe and a second lobe, which is close to the first lobe, the second inner section of the first lobe being connected to the first inner section of the second lobe by an inner end ply thereof.
  • the peripheral part is of frustoconical shape around the central axis.
  • the peripheral part is of circular cylindrical shape around the central axis.
  • the lobes delimit between them a central space containing the central axis.
  • At least three lobes are provided.
  • five lobes are provided.
  • a sheet delimiting an axial tube intended to contain tobacco is glued to an axial end of the peripheral part in the extension of the peripheral part.
  • a second object of the invention is a cigarette characterized in that it comprises a cardboard filter as described above.
  • a third object of the invention is a process for manufacturing the filter as described above, filter in which the lobes delimit between them a central space containing the central axis, characterized in that the process comprises a step of immobilization of the filter, in which the filter is threaded by a machine through its central space around a spindle to hold the filter, then a step of fixing a sheet delimiting an axial tube intended to contain tobacco, in which the sheet is glued by the machine in the extension of the peripheral part on an axial end of the peripheral part of the filter held on the spindle, then a step of separating the filter from the spindle.
  • the filter 1 comprises a strip 2 of cardboard, such as for example that shown in figure 7 , which was folded, then rolled up, then glued during an automated manufacturing process on a mass production machine, to obtain the three-dimensional shape of the filter 1, such as for example that shown in figures 1 to 6 And 8 to 11 .
  • This filter 1 is therefore made of cardboard and is intended to form a filter 1 or mouthpiece 1 for cigarettes, that is to say the end part of the cigarette, to be placed in the mouth of the smoker.
  • the filter 1 comprises, in the folded state of the strip 2 of cardboard, a central part 21 having lobes equidistributed angularly around a central axis 22 of the filter 2.
  • Three lobes or more than three lobes may be provided.
  • five lobes 3, 4, 5, 6, 7 are provided.
  • the lobes are generally designated below by the reference signs 3, 4, 5, 6, 7, but of course a number of lobes other than five can be provided.
  • the lobes 3, 4, 5, 6, 7 are for example in the shape of a flower centered on the axis 22 and surrounded by the peripheral part, the petals of the flower being formed by the lobes.
  • Each lobe can be formed from a variable number of sections folded together one after the other and/or superimposed, for example from 3 to 10 sections.
  • Each section can be flat, as for example in the embodiments shown in the figures.
  • THE lobes can have the same shape and/or identical sections, as for example for the lobes 3, 4, 5, 6 in the embodiments shown in the figures.
  • An embodiment is described below in more detail where each lobe 3, 4, 5, 6, 7 is generally triangular in shape and where each lobe 3, 4, 5, 6 is formed of three sections folded together.
  • the advantage of this form is also of an industrial nature. This design makes it possible to manufacture the cardboard filter in a single operation from a reel of cardboard, unrolled and cut, for example according to the figure 7 .
  • the advantage of this unwinding and cutting operation is to automate the manufacture of the filters on a machine.
  • the filter 1 comprises, in the folded and rolled state of the strip 2 of cardboard, a peripheral part 23 surrounding the central part 21 and therefore surrounding the lobes.
  • the lobes and the peripheral part 23 are therefore formed by a single strip 2 of continuous cardboard.
  • the central part 21 comprises channels 24 for passing gas. These gas passage channels 24 are delimited by the lobes 3, 4, 5, 6, 7 and by the peripheral part 23 and are therefore located around the central axis 22.
  • the gas passage channels 24 are regularly distributed around the central axis 22 of the filter 2.
  • the channels 24 of gas passage located in the lobes 3, 4, 5, 6, 7 are thus substantially identical and have a substantially identical section.
  • These gas passage channels 24 located in the lobes 3, 4, 5, 6, 7 are those of the widest section compared to the gas passage channels 24 located outside the lobes 3, 4, 5, 6 , 7 between these and the peripheral part 23.
  • the number of channels 24 is twice as high as the M folding known from the document FR-A-3 057 441 .
  • the gas passage channels 24 inside the lobes 3, 4, 5, 6, 7 can thus have a section close to half that of the channels of the M-shaped filter known from the document FR-A-3 057 441 .
  • the filter 1 thus ensures a uniform distribution of the stresses of each ply of the cardboard strip. This homogeneity and the large number of folds allow regular rolling of the peripheral zone and gives great rigidity to the filter. three-dimensional and a regular expansion of each lobe against the peripheral zone 23. The lobes provide reinforced support for the peripheral part 23.
  • the smoker thus has a prefabricated three-dimensional filter 1 at his disposal.
  • the smoker can himself stick a sheet 8 delimiting an axial tube 81 intended to contain tobacco on an axial end 231 of the peripheral part 23 in the extension of the peripheral part 23, as shown in Figures 5, 6 , 9 and 10 .
  • the invention also provides a prefabricated assembly, consisting of the filter 1 and the sheet 8 glued thereto, as will be described below.
  • the strip 2 of cardboard has at least one area 9 of bonding to itself.
  • the bonding zone 9 is located on the peripheral part 23.
  • the outer end zone 232 of the strip 2 of cardboard located in the peripheral part 23 is glued to another zone 233 underlying this peripheral part 23.
  • This bonding zone 9 extends for example along a line 91 along the axis 22, this line 91 being for example rectilinear.
  • each lobe 3, 4, 5, 6, 7 comprises at least one outer part or at least one outer section 31, 41, 51, 61, 71 having one or more contact points or edges against the peripheral part 23.
  • Each outer part or outer section 31, 41, 51, 61, 71 can be formed from one section or from several sections folded together.
  • each lobe 3, 4, 5, 6, 7 is in contact with the peripheral part 23 by the first outer folds 320, 420, 520, 620, 720 at the end of the outer section 31, 41, 51 , 61, 71 and by the second outer folds 330, 430, 530, 630, 730 at the end of the outer section 31, 41, 51, 61, 71.
  • the outer section 31, 41, 51, 61, 71 thus serves as support on the peripheral part 23.
  • the second inner section 33, 43, 53, 63 of the first lobe 3, 4, 5, 6 is connected to the first inner section 42, 52, 62, 72 of the second lobe 4, 5, 6, 7 by an inner fold 44, 54 , 64, 74 end thereof.
  • the second inner section 73 of the lobe 7 is connected to the first inner section 32 of the second lobe 3 by an inner end ply 34 thereof.
  • the peripheral part 23 of the filter 1 can be of substantially strunconic shape around the central axis 22, as shown for example in figure 1 , 2 , 3, 4 , 5, 6 , 7 And 11 .
  • the peripheral part 23 may be of substantially cylindrical shape, for example substantially circular cylindrical, around the central axis 22, as shown for example in figure 8 , 9 and 10 .
  • a sheet 8 delimiting an axial tube 81 intended to contain tobacco is glued to the outer surface of the axial end 231 of the peripheral part 23 in the extension of the peripheral part 23, as shown in Figures 5, 6 , 9 and 10 .
  • the sheet 8 is glued to itself at its longitudinal ends along the axis 22. This bonding is for example carried out in an automated manner on a mass-produced machine, for example by using the manufacturing method described below.
  • a cigarette can thus comprise this sheet 1 fixed to the filter 1.
  • the smoker having obtained the prefabricated assembly consisting of the filter 1 and the sheet 8 glued to the filter 1 can then introduce tobacco into the axial tube 81 through its opening 82 d far end of the filter 1.
  • the filter 1, the sheet 8 and the axial tube 81 are substantially tapered around the axis 22 (the sheet 8 being glued to the axial end 231 of the peripheral part 23, which is the widest with respect to the other axial end 235 of the filter 1.
  • the filter 1, the sheet 8 and the axial tube 81 are substantially cylindrical, for example substantially circular cylindrical, around the axis 22.
  • the lobes 3, 4, 5, 6, 7 delimit between them a central space 220 containing the central axis 22.
  • this central space 220 (which is also a gas passage channel) is located between the inner folds 34, 44, 54, 64, 74 of the inner sections 32, 42, 52, 62, 72, 33, 43, 53, 63, 73.
  • This central space 220 makes it possible to introduce a holding pin B the filter to fix the sheet 8 on it delimiting the axial tube 81 intended to contain tobacco, as shown in Figures 5, 6 , 9 , 10 And 11 .
  • An automated method of manufacturing the assembly consisting of the prefabricated filter 1 and the sheet 8 glued to the filter 1 may comprise the steps described below.
  • the filter 1 is threaded by a machine through its central space 220 around a pin B to hold the filter 1.
