Abstract
吸烟制品例如香烟,其焦油释放量不大于6mg,过滤嘴通风值为至少为50%,通风段位于离过滤嘴接触嘴一端不小于过滤嘴长度的75%,该吸烟制品有高的主烟雾流水焦油比。
Description
本发明涉及吸烟制品。
低焦油释放量香烟的吸烟者称,由香烟产生的主烟雾流具有干性特征。
本发明的目的是提供有高水焦油比主烟雾流的低焦油释放量香烟。
根据本发明,吸烟制品含有吸烟材料条和过滤嘴,该制品的无尼古丁干颗粒物(NFDPM)在标准机器吸烟条件下不大于约6毫克,过滤嘴通风至少达50%通风值,吸烟制品的特征在于,通风段在离其接触嘴一端不小于过滤嘴长度的约75%处,且所述的吸烟制品有高的水焦油比主烟雾流,其值(×100)至少为6。
EP-A-0474940公开了一种无上段特征的吸烟制品。
优选的是,本发明的吸烟制品通风率至少为60%。通风段在离接触嘴一端不小于过滤嘴长度的约80%处。通风段在离其接触嘴一端最好至少20毫米,通风段在离其接触嘴一端24毫米或更长处。
优选的是,过滤嘴是单过滤嘴,其整个长度基本上至少具有均匀的内部结构。过滤嘴可含有醋酸纤维素纤维来作为过滤材料。
当在标准(ISO)机器吸烟条件下吸香烟时,吸烟机每分钟内持续2秒吸取35毫升烟。通风率为由通风空气形成35毫升烟的百分数。
这里使用的术语“焦油”指主烟雾流中所有无尼古丁干颗粒物。它在标准机器吸烟条件下,使用Cambridge过滤嘴座,按标准步骤测量。优选的是,本发明的吸烟制品的无尼古丁干颗粒物释放量不大于约5.5毫克。它可低到2~3毫克。
按本发明香烟的通风可用机械的、激光的或静电的方法得到,可采用环形穿过过滤嘴的单排孔的形式,或者更宽的穿孔区的形式。如果这样的区显著宽,即尺寸沿过滤嘴纵向扩大,那么在接近过滤嘴接触嘴一端;该区的一侧空气流速较高,而在另一侧空气流速较低。在这样的情况下,取离过滤嘴接触嘴一端穿孔区的距离为从嘴一端到有效通风中值点的距离,后者为通风区中的一个位置,此处上游每单位时间的总通风空速流量等于此处下游每单位时间总的通风空气流量。
实施例
对比香烟和本发明的香烟有以下共同的特征。
烟草: 弗吉尼亚烟草
烟草条长度: 67毫米
过滤嘴类型: 醋酸纤维素单过滤嘴
过滤嘴长度: 27毫米
通风类型: On-Machine Laser:单线
通风率(%): 60%
对于对比香烟来说,通风线在离过滤嘴接触嘴一端12毫米处,而对于本发明的香烟来说,通风线在离过滤嘴接触嘴一端25毫米处。
对比香烟和本发明香烟的焦油释放量分别为5.30和5.80(毫克/根香烟)。水的释放量分别为0.25和0.43(毫克/根香烟)。因此,对比香烟的水焦油比(×100)为4.70,而本发明香烟为7.40。吸烟者称,本发明香烟的主烟雾流的质量优于对比香烟。
