Abstract

There are provided with a plurality of filter materials ( 2 ) spaced out in a line and whose filter fiber is exposed on the surface thereof; a capsule ( 3 ) arranged between the filter materials ( 2 ) and in which content liquid to be used as a flavoring agent or adsorbent is enclosed; shaping paper ( 4 ) that covers the filter materials ( 2 ) and the capsule ( 3 ), connects the filter materials ( 2 ) to each other, and includes permeation-preventing material for preventing the permeation of the content liquid; and an adhesion device ( 5 ) for adhering the filter materials ( 2 ) and the shaping paper ( 4 ) to each other in between the filter materials ( 2 ) and the shaping paper ( 4 ) over the entire circumference of the filter materials ( 2 ) and the shaping paper ( 4 ).

First claim

The invention claimed is:

1. A cigarette filter to which a tobacco rod filled with shredded tobacco is connected, comprising:
a plurality of filter materials spaced out in a line, each filter material including filter fiber;
a capsule arranged between the filter materials and enclosing content liquid to be used as a flavoring agent or adsorbent;
shaping paper that covers the filter materials and the capsule and connects the filter materials to each other;
a permeation-preventing material applied to or impregnated into the shaping paper to prevent permeation of the content liquid into the shaping paper; and
an adhesion device for firmly attaching the filter materials and the shaping paper to each other in between the filter materials and the shaping paper over a part of or the entire circumference of the filter materials and the shaping paper,
wherein among the filter materials, at least one filter material situated nearer the tobacco rod in relation to the capsule is a non-wrapped filter segment whose filter fiber is exposed on a surface thereof, and
wherein the permeation-preventing material is water-proof wax or oil-proof wax applied to the entire area wherein the shaping paper and the filter materials are firmly attached together.

2. The cigarette filter according to claim 1 , wherein the shaping paper is water-proof paper with water resistance, oil-proof paper with oil resistance or water and oil-proof paper with water and oil resistance.

3. A cigarette filter to which a tobacco rod filled with shredded tobacco is connected, comprising:
a plurality of filter materials spaced out in a line, each filter material including filter fiber;
a capsule arranged between the filter materials and enclosing content liquid to be used as a flavoring agent or adsorbent;
shaping paper that covers the filter materials and the capsule and connects the filter materials to each other;
an adhesion device for firmly attaching the filter materials and the shaping paper to each other in between the filter materials and the shaping paper over a part of or the entire circumference of the filter materials and the shaping paper,
wherein among the filter materials, at least one filter material situated nearer the tobacco rod in relation to the capsule is a non-wrapped filter segment whose filter fiber is exposed on a surface thereof, and
wherein the adhesion device is a gap-filling layer for filling a gap between the shaping paper and the non-wrapped filter segment.

4. The cigarette filter according to claim 1 , wherein the adhesion device is an adhesive agent with an adherence property.

5. A capsule filter cigarette comprising:
the cigarette filter claimed in claim 1 , and
tipping paper that covers an entire circumference of the cigarette filter and wraps an end portion of the tobacco rod together with the cigarette filter to hold the tobacco rod and the cigarette filter together.

6. The cigarette filter according to claim 3 , wherein the shaping paper is water-proof paper with water resistance, oil-proof paper with oil resistance or water-proof and oil-proof paper with water and oil resistance.

7. The cigarette filter according to claim 3 , wherein the adhesion device is an adhesive agent with an adherence property.

8. A capsule filter cigarette, comprising:
the cigarette filter claimed in claim 3 ; and
tipping paper that covers an entire circumference of the cigarette filter and wraps an end portion of the tobacco rod together with the cigarette filter to hold the tobacco rod and the cigarette filter together.
