Definitions

  • the present invention relates to a method for producing a hollow cigarette filter member.
  • a filter such as a tubular filter which has an inner cavity extending in its axial direction.
  • such a hollow filter is generally produced from cellulose acetate fiber and a plasticizer.
  • a cigarette filter produced from a material other than cellulose acetate fiber, such as polypropylene fiber, is also known.
  • Patent Literature 1 describes a method in which a non-woven web comprising thermoplastic fiber is formed into a cylindrical shape (Pages 6 to 7). This literature describes that a hollow filter is produced using a cigarette wrapping machine having a double cone comprising an inner cone and an outer cone by wrapping the fibrous web around the outer periphery of the inner cone.
  • a conventional hollow cigarette filter is produced by forming thermoplastic fiber into a hollow filter, and therefore has a problem in its appearance because fragments of the fiber constituting the filter may be looked as a texture on the inner cavity of the filter. Further, the conventional hollow cigarette filter also has a problem that its production process, including spinning of thermoplastic fiber and forming thermoplastic fiber into a hollow filter, takes time, which leads to an increase in production cost.
  • the present inventors have employed a method in which a hollow cigarette filter is formed by thermoforming a material containing cellulose acetate without using cellulose acetate fiber.
  • the present invention relates to a method for producing a hollow cigarette filter member, comprising forming a hollow cigarette filter member by thermoforming a raw material containing a cellulose ester and an ester-based plasticizer without having the raw material undergo a fibrous shape.
  • the hollow cigarette filter member by melt-extrusion molding of pellets containing the cellulose ester and the ester-based plasticizer.
  • the hollow cigarette filter member by attaching the ester-based plasticizer to cellulose ester flakes and subjecting the flakes to compression molding with heating.
  • the ester-based plasticizer is preferably one containing triacetin but not containing a phosphoric acid ester.
  • the production method of the present invention it is possible to quickly produce a hollow cigarette filter having no fiber fragment textured on its inner cavity. Further, the hollow cigarette filter uses cellulose acetate as its material, and therefore there is no fear that the hollow cigarette filter adversely affects the taste of a cigarette and health.
  • Fig. 1 is a sectional view of a mouthpiece-side end of a cigarette, which is taken along the axial direction of the cigarette.
  • a cigarette 1 comprises a cigarette rod 2 comprising cut tobacco and a cigarette filter 3 connected to one end of the cigarette rod 2.
  • the cigarette rod 2 is wrapped by cigarette paper, but the cigarette paper is not shown.
  • the cigarette filter 3 comprises a solid-core cigarette filter member 5 having no inner cavity, a hollow cigarette filter member 6 connected to downstream of the member 5 and having a through hole 7 extending in its axial direction, and tipping paper 4 wrapped around the outside of the members 5 and 6.
  • the hollow cigarette filter member refers to a filter member that constitutes a cigarette filter having a cavity passing through it in its axial direction when wrapped by tipping paper.
  • a hollow cigarette filter member has a cylindrical shape having an inner cavity passing through a cylinder in its axial direction or has a shape having recesses continuously formed in the outer periphery of a cylinder in its axial direction.
  • Fig. 1 is a sectional view of the cylindrical cigarette filter member 6 along its axial direction.
  • Figs. 2(a) to 2(c) are each a sectional view (sectional view along a direction perpendicular to an axial direction) of a hollow cigarette filter formed by wrapping a hollow cigarette filter member by tipping paper.
  • Fig. 2(a) shows a cylindrical cigarette filter member having a through hole 7 in its center.
  • recesses 8 are provided in the outer periphery of the cigarette filter member.
  • the recesses 8 are continuously formed in the axial direction of the cigarette filter member so that when the outside of the cigarette filter member is wrapped by tipping paper, cavities are formed between the cigarette filter member and the tipping paper so as to pass through the cigarette filter in its axial direction.
  • the filter member shown in Fig. 1(b) has recesses provided by allowing the filter member to have a wavy outer periphery
  • the filter member shown in Fig. 1(c) has a shape obtained by forming recesses intermittently in the outer periphery of a cylinder, but the hollow cigarette filter member is not limited thereto. In either case, the cigarette filter can have cavities passing through it in its axial direction when the outside of the filter member is wrapped by tipping paper.
  • the present invention is directed to a method for producing such a hollow cigarette filter member as described above.
  • a hollow cigarette filter member is produced by forming thermoplastic fiber into a hollow member.
  • a hollow cigarette filter member is produced by thermoforming without having the raw material undergo a fibrous shape.
  • thermoforming refers to forming a cigarette filter member into a hollow shape with heating.
  • thermoforming without having the raw material undergo a fibrous shape, it is possible to avoid a problem in appearance of texture on the inner cavity of a hollow cigarette filter. Further, it is also possible to avoid the necessity for performing a spinning process etc. and therefore to quickly produce a hollow cigarette filter.
  • a raw material containing a cellulose ester and an ester-based plasticizer is used as a raw material constituting a hollow cigarette filter member. It is preferred that triacetin is used but a phosphoric acid ester is not used as the ester-based plasticizer. Therefore, there is no fear that the hollow cigarette filter member adversely affects the taste of a cigarette and health.
  • the cellulose ester used in the present invention is a known one, and specific examples thereof include cellulose acetate, cellulose propionate, cellulose butyrate, cellulose acetate propionate, and cellulose acetate butyrate.
  • Other examples of the cellulose ester include polycaprolactone grafted cellulose acetate, acetyl methyl cellulose, acetyl ethyl cellulose, acetyl propyl cellulose, acetyl hydroxyethyl cellulose, and acetyl hydroxypropyl cellulose.
  • the cellulose ester is preferably one having an average degree of substitution of 2.7 or less, and is more preferably one having an average degree of substitution of 1.7 to 2.7.
  • the polymerization degree of the cellulose ester is about 100 to 1000, preferably about 100 to 500 in terms of viscosity-average polymerization degree.
  • triacetin glycerol triacetate
  • citric acid esters citric acid esters
  • phosphoric acid esters are preferred.
  • triacetin it is preferred that triacetin is used but a phosphoric acid ester is not used as the ester-based plasticizer.
  • Triacetin has been used for many years as a plasticizer in cigarette filters, and therefore the use of only triacetin as the ester-based plasticizer has no fear that health and the taste of a cigarette are adversely affected.
  • Triacetin that can be used in the present invention is not limited to one composed of only triacetin pure in its chemical structure, and may be one that has a triacetin purity of, for example, 80 wt% or more, preferably 90 wt% or more and contains monoacetin and/or diacetin as the rest.
  • the phosphoric acid ester that can be used in the present invention is a known one.
  • a phosphoric acid ester described in JP 2003-261711 A as a flame retardant may be used.
  • the amount of the ester-based plasticizer blended may be about 10 to 30 wt%, preferably 20 to 30 wt% per 100 parts by weight of cellulose acetate.
  • the amount of the ester-based plasticizer blended is within the above range, a hollow cigarette filter member can be produced by thermoforming without having the raw material undergo a fibrous shape.
  • the raw material used in the present invention may contain a commonly-used additive.
  • a commonly-used additive examples include other stabilizers (e.g., antioxidants, ultraviolet absorbers, heat stabilizers, and light resistant stabilizers), colorants (e.g., dyes and pigments), flame retardants, antistatic agents, lubricants, anti-blocking agents, dispersants, fluidizers, dripping inhibitors, and antimicrobial agents.
  • stabilizers e.g., antioxidants, ultraviolet absorbers, heat stabilizers, and light resistant stabilizers
  • colorants e.g., dyes and pigments
  • flame retardants e.g., antistatic agents, lubricants, anti-blocking agents, dispersants, fluidizers, dripping inhibitors, and antimicrobial agents.
  • white pigment titanium oxide can be used as a white pigment.
  • a hollow cigarette filter member can be formed by producing pellets from the raw material containing the cellulose ester and the ester-based plasticizer and then subjecting the pellets to melt-extrusion molding.
  • a specific method for producing the pellets is not particularly limited.
  • components of the above-described raw material are first preliminarily mixed by a dry or wet method using a mixer such as a tumbler mixer, a Henschel mixer, a ribbon mixer, or a kneader, to prepare a mixture, and then the mixture is melt-kneaded by an extruder such as a single or twin screw extruder and formed into pellets.
  • a specific method for forming a hollow cigarette filter member from the pellets by melt-extrusion molding is not particularly limited.
  • the method include injection molding, extrusion molding, vacuum molding, profile molding, foaming molding, injection pressing, press molding, blow molding, and gas injection molding.
  • a hollow cigarette filter member is formed by attaching the ester-based plasticizer to the surface of cellulose ester flakes and subjecting the flakes to compression molding with heating.
  • the compression molding may be performed using a commercially-available compression molding machine at a temperature of 150°C to 240°C, desirably 230°C and a pressure of 0.01 MPa or more, desirably 0.5 MPa for 30 seconds or more, desirably about 2 minutes.
