Description
Ti ppi ng Paper With Thermally Expandable Particles The i nvent i on r el at es to a mout hpi ece I i ni ng paper with thermal I y expandable part i cl es.
The i nvent i on r el at es i n part i cul ar to mout hpi ece I i ni ng paper for cigarettes and heat- not- burn consumer articles or, in general , to mout hpi eces of aerosol - gener at i ng consumer art i cl es.
The mout hpi ece I i ni ng paper, of ten ref erred to as "ti ppi ng paper" or 'ti' ppi ng" for short, i s that part of the aerosol gener at i ng consumer art i cl e whi ch i s touched by the person' s I i ps when smoki ng a filter ci garett e or when heat i ng the heat-not-burn consumer article. The mout hpi ece I i fling paper envel ops the filter part and usual I y al so protrudes slightly in the I ongi t udi nal di r ect i on of the consumer art i cl e i nt o the longitudinal regi on of the tobacco rod or the aerosol-generating substrate and there envel ops the ci garette paper or the wrappi ng mat er i al of the aerosol - gener at i ng substrate. The mout hpi ece I i ni ng paper forms the outermost wrappi ng mat eri al of an aerosol - gener at i ng consumer ar t i cl e and, i n contrast to ci gar ette paper, i s not burned when the consumer art i cl e i s used.
The mout hpi ece I i ni ng paper is in most cases actual I y a paper, but it can al so be a foil or a composite mat eri al made of sever al I ayers of different mat er i al s.
The mout hpi ece I i ni ng paper oft en compri ses an i mpri nt . For exampl e, this i mpri nt can be an i mi t at i on of cork. However, mout hpi ece I i ni ng papers whi ch are white i n the area that i s touched by the I i ps are al so used.
U59307789B2 teaches appl yi ng a structure made of I acquer to a mout hpi ece I i ni ng paper. The structured appl i cat i on of the I acquer requi res a precisely operating appl i cation devi ce.
The obj ect of the present i nvent i on is to provide a structured mout hpi ece I i ni ng paper and an i mpr oved met hod for produci ng a structured mout hpi ece I i ni ng paper.

The mouthpi ece I i ni ng paper contai ns thermal I y expandabl e part i cl es whi ch can be expanded by the act i on of heat to produce a rai sed structure or at least an elevation.
I n one embodi ment, the thermal I y expandable part i cl es are contai ned i n the substrate of the mouthpi ece I i ni ng paper.
The substrate i s preferably paper, in particular a so-called base paper with a grammage of 30 to 60 g/m2, part i cul an I y preferably 30 to 50 g/m2.
Less preferably, i n addition to the base paper, the substrate can compri se a foil , i n part i cul ar made of cell ul ose hydrate.
Less preferably, the substrate can consi st of a foil , i n part i cul ar of cell ul ose hydrate, or be present as a I ami nate of several f oi I s. I n these cases, the thermal I y expandabl e part i cl es can be contai ned in a f oi I .
Preferably, the mouthpi ece I i ni ng paper is actual I y a paper and the thermal I y expandable part i cl es are contai ned i n the paper, i n part i cul ar i n that they are end l osed i n the f i bre matrix of the paper dun i ng the papermaki ng process.
I n a second embodi ment, the thermal I y expandabl e part i cl es are contai ned i n a pri nt or coati ng. The thermal I y expandabl e part i cl es can be applied with a non- f i I m- f ormi ng pri nt i ng i nk or a fil m- f or mi ng clear lacquer or a fil m- f ormi ng col oured lacquer.
The part i cl es are preferably expanded by the act i on of heat when a web of mouthpi ece I i ni ng paper i s transported al ong a hot cyl i nder or a hot embossi ng roil er of a hot stampi ng machi ne.
In a fi rst embodi ment, only heat i ng takes pl ace, so that, contrary to convent i onal use of the hot stampi ng machi ne, no hot stampi ng foil is transferred.
I n a second embodi ment, a hot stampi ng foil is transferred i n addi ti on to the heat i ng or with the heat i ng. As a result, there i s a hot stampi ng foil on the rai sed areas whi ch are formed by

I n another embodi ment, the heat i ng takes pl ace on the mouthpi ece lining paper when it is al ready present on an aerosol-generating consumer product. The mouthpi ece I i ni ng paper forms the out er I ayer of the consumer article. The heat i ng i s preferably carried out before the consumer art i cl e i s packaged for sal e. I n another embodi ment, the heat i ng takes place when the consumer art i cl e is used by the consumer, for exampl e by heat i ng the consumer article in a heat - not - bur n devi ce.
I n one embodi ment, a pri nt i ng or coati ng whi ch compri ses thermal I y expandable particles is appl i ed over a cont i nuous surf ace to the mouthpi ece I i ni ng paper, the subsequent structure bei ng formed by heat i ng with a structured heat i ng surface.
I n one embodi ment, a pri nt i ng or coati ng whi ch has thermal I y expandable part i cl es is applied i n a structured manner to the mouthpi ece I i ni ng paper. I n t hi s case, the subsequent structure can al so be formed by heat i ng with a fl at heat i ng surf ace or by heat i ng an aerosol - generat i ng consumer art i cl e whi ch i s provi ded wit h t he mout hpi ece I i ni ng paper.

I n one embodi ment, the expandable part i cl es are applied with a I acquer and are thus cont al ned in a I acquer I ayer on the mout hpi ece I i ni ng paper.
The term I acquer i ncl udes al I ki nds of f i I m- f ormi ng substances.
In a fi rst embodi ment, the I acquer i s a cl ear I acquer whi ch hardens to form a transparent I acquer I ayer.
The cl ear I acquer is particularly preferably a ni trocel I ul ose I acquer.
The cl ear I acquer preferably compri ses ni trocel I ul ose or ethyl cell ul ose, the thermal I y expandabl e particles and one or more sol vents sel ect ed from the group of sol vents compri Si ng:
ethanol , ethyl acetate, i sopropanol . The sol vents ment i oned can be present i n the form of an aqueous sol uti on, so that the pai nt compri ses thermal I y expandable part i cl es, ni trocel I ul ose or ethyl cell ul ose, an organic sol vent and water. The clear lacquer can al so compri se effect pi gments.
The cl ear I acquer composi ti on i s preferably appl i ed i n an amount of 0. 25 g/m2 to 2 g/m2, particularly preferably 0.5 g/m2 to 1 gi m2 .
I n a second embodi ment, the I acquer i s a col oured I acquer whi ch hardens to form a col oured lacquer layer.
The col oured I acquer compri ses ni trocel I ul ose or ethyl cell ul ose, the thermal I y expandabl e particles and col our pi gments and one or more sol vents sel ect ed from the group of sol vents compri si ng: ethanol , ethyl acetate, i sopropanol .

I n Fl G. 2, a band of a foil el ement 9 i s al so ill ust rat ed, whi ch was appl i ed to the mout hpi ece I i ni ng paper 1 by hot st ampi ng. As a result of the act i on of heat dun i ng hot st ampi ng, the part i cl es underneath the band of the f oi I el ement 9 are expanded, so that an el evat i on 10 i s present, whi ch i s regi st ered with the band of the foil el ement 9.

I n this case, heating of the mout hpi ece I i ni ng paper 1 causes the part i cl es i n the pri nt i ng or I acquer I ayer 2

The foil el ement 9 i I I ust rat ed i n FIG. 4 I n the area of the substrate not pr ovi ded with the pri nt i ng or I acquer I ayer 2 thus does not produce any el evati on 10. As ill ust rated i n FIGS. 3 and 4, the elevations 10 are present i n the pri nti ng or lacquer I ayer 2 and can be formed by the act i on of I ocal heat with or without attachment of a foil el ement 9.
