Description

提供改进的香味增强的多部件过滤器 It provides improved flavor enhancement of the multi-component filter

技术领域 FIELD

[0001] 本发明涉及一种用于发烟制品的多部件过滤器,并且涉及一种包括这种多部件过滤器的发烟制品。 [0001] The present invention relates to a smoking article multi-component filter, and to a smoking article comprising such a multi-component filter.

背景技术 Background technique

[0002] 过滤器香烟通常包括由纸包装材料包围的配方烟丝条和与卷制的烟丝条以端对端关系对准并且通过接装纸连接到其上的圆柱状过滤器。 [0002] Filter cigarettes typically include a tobacco rod surrounded by the formulation of paper and packaging material with the rolled tobacco rod end to end aligned relation and connected to a cylindrical filter through which the tipping paper.

[0003] 在传统的带过滤器香烟中,过滤器通常包括卷制在多孔成型纸(plug wrap)中的醋酸纤维素丝束棒。 [0003] In a conventional cigarette with a filter, the filter typically comprises a roll of cellulose acetate tow in the porous wrap (plug wrap) of. 但是,还已知有具有多部件过滤器的过滤器香烟,所述多部件过滤器包括用于去除主流烟气的微粒和气体成分的两个或多个过滤材料部分。 However, there is also known a filter cigarette having multi-component filter, the multi-component filter comprises two or more filters for removing particulate material portions and gas components of the mainstream smoke. 为了增强在卷制的烟丝条燃烧过程中产生的主流烟气的香味,还已知了提供具有包括香料的过滤器的带过滤器香烟。 To enhance the flavor of the mainstream smoke produced during combustion of the tobacco rod rolling is also known to provide a cigarette with a filter having a filter comprising a fragrance.

[0004] W0-A-03/059096公开了一种具有多部件过滤器的香烟,所述多部件过滤嘴包括带香味球形珠状活性炭层和位于带香味球形珠活性炭下游的香味释放部分,所述香味释放部分包括其上具有香料的纱线(yarn)。 [0004] W0-A-03/059096 discloses a cigarette having multi-component filter, the multi-component filter comprising flavored beaded activated carbon layer and a spherical flavor flavored spherical beads located downstream of the activated release portion, said the flavor release segment comprises a perfume having thereon a yarn (yarn). 由于珠状活性炭为吸收剂,因此即使当香味饱和时,香味仍不会从带香味珠状活性炭释放到被抽吸通过多部件过滤器的主流烟气中。 Since the bead activated carbon as absorbent, even when saturated aroma, flavor is released from the activated carbon does not remain scented bead to be drawn through the multi-component filter mainstream smoke.

[0005] 期望提供一种用于比如香烟的发烟制品的多部件过滤器,当主流烟气从可发烟材料条抽吸通过过滤器时,所述多部件过滤器向主流烟气提供改进的香味增强。 [0005] desirable to provide a multi-component filter, such as smoking articles such as cigarettes for the mainstream smoke when the cigarette can be made from a strip of material drawn through the filter, the multi-component filter to provide improved mainstream smoke the flavor enhancement.

发明内容 SUMMARY

[0006] 根据本发明,提供一种用于发烟制品的多部件过滤器,包括:接近过滤器的嘴端部的第一香味释放部分;和紧接地设置在第一香味释放部分上游的第二香味释放部分,其中, 所述第一香味释放部分包括至少一根香味承载丝(flavour-bearing thread),而且所述第二香味释放部分包括香味承载纤维素颗粒(cellulosic particle)。 [0006] According to the present invention, there is provided a multi-component filter for a smoking article, comprising: a first filter close the mouth end of the flavor release portion; and the second is arranged immediately upstream of the first flavor-releasing segment two flavor release segment, wherein the first flavor-releasing segment comprises at least one flavor-bearing threads (flavour-bearing thread), and the second flavor-releasing segment comprises flavor-bearing cellulosic particles (cellulosic particle).

[0007] 根据本发明,还提供一种发烟制品,包括:可发烟材料条;和多部件过滤器,所述多部件过滤器包括:接近过滤器的嘴端部的第一香味释放部分;和紧接地设置在所述第一香味释放部分上游的第二香味释放部分,其中,所述第一香味释放部分包括至少一根香味承载丝,而且所述第二香味释放部分包括香味承载纤维素颗粒。 [0007] The present invention further provides a smoking article comprising: a smokable material; and a multi-component filter, the multi-component filter comprising: a first filter close the mouth end of the flavor release portion ; and immediately provided in the first flavor-releasing portion upstream of the second flavor release portion, wherein the first flavor-releasing segment comprises at least one flavor-bearing threads, and the second flavor-releasing segment comprises flavor-bearing fibers granules.

[0008] 在本发明的多部件过滤器和发烟制品的替代实施例中,第二香味释放部分包括由烟草植物材料制成的香味承载颗粒。 [0008] In an alternative multi-component filter according to the present invention and the smoking article embodiment, the second flavor-releasing segment comprises flavor made from tobacco plant material carrying particles.

[0009] 在整个说明书中,“上游”和“下游”用于描述在使用过程中本发明的多部件过滤器的部分相对于被从可发烟材料条抽吸通过多部件过滤器的主流烟气方向的相对位置。 Mainstream smoke [0009] Throughout the specification, "upstream" and "downstream" are used to describe part of multi-component filter during use with respect to the present invention is drawn through the multi-component filter from the rod of smokable material strip the relative position of the air direction.

[0010] 当主流烟气被从可发烟材料条抽吸通过多部件过滤器时,随着烟气经过第二香味释放部分,香味从香味承载纤维素颗粒释放到主流烟气中。 [0010] When mainstream smoke drawn through the multi-component filter from the rod of smokable material may be, as the smoke passes through the second flavor-releasing segment, flavor-bearing cellulosic particles are released into the mainstream smoke from the flavor. 其后,当烟气经过第一香味释放部分时,另外的香味从一根或多根香味承载丝释放到主流烟气中。 Thereafter, when the flue gas passes through the first flavor-releasing segment, additional flavor is released from the one or more flavor-bearing threads into the mainstream smoke. 由此,根据本发明的多部件过滤器的两个相邻香味释放部分有利地使释放到消费者口中的香味最大化。 Accordingly, release portion advantageously allows a consumer's mouth to release flavor into the two adjacent flavor according to maximize multi-component filters according to the present invention.
