    • PROBLEM TO BE SOLVED: To provide a means and method for controlling intrusion of external air into an additive material contained in a filter of a tobacco. SOLUTION: A ring 500 for controlling intrusion of external air into the additive material in the filter contains one opening 510, and a chipping material 400 contains three openings arranged on a circumferential direction of the filter interposing spaces between the openings. These three openings of the chipping material 400 are aligned to the positions of three grooves of the filter in radial directions to introduce the external air to the grooves and pass the air through the additive material. These three openings of the chipping material 400 are positioned immediately below the ring to align the opening 510 of the ring 500 to the opening of the chipping material 400 in axial direction and, accordingly, intrusion of external air into a specific groove is inhibited unless the opening 510 of the ring 500 is aligned to the opening of the chipping material 400 corresponding to the groove.

    • 要解决的问题:提供一种控制外部空气侵入包含在烟草过滤器中的添加剂材料的方法和方法。 解决方案:用于控制外部空气进入过滤器中的添加剂材料的环500包含一个开口510,并且碎屑材料400包含在过滤器的周向上布置的三个开口,该开口在开口之间插入空间。 切屑材料400的这三个开口在径向方向上与过滤器的三个凹槽的位置对齐,以将外部空气引入凹槽并使空气通过添加剂材料。 切屑材料400的这三个开口位于环的正下方,以使环500的开口510在轴向方向上对准切屑材料400的开口,因此外部空气侵入特定的凹槽中被禁止,除非 环500的开口510与对应于凹槽的切屑材料400的开口对准。 版权所有(C)2011,JPO&INPIT
