Detailed description of the invention
If with reference to Fig. 1, as smoking article, illustrate the essential structure of cigarette with filter tip 10 of the present invention.The composite filter-tip 16 that this cigarette with filter tip 10 comprises cigarette 12, is connected with one end of cigarette 12 via the winding of joint paper 14, this composite filter-tip 16 forms drum.
Composite filter-tip 16 also has two filtering element 18,20.These filtering element 18,20 form drum, and the axis direction along cigarette 12 leaves mutually.Filtering element 18,20 is such as formed by the bundle of the filtering material such as acetate fiber or paper, the roll web that wraps up this bundle.The filtering element 18 being positioned at cigarette 12 side can at the bundle of filtering material containing the particle such as activated carbon or spices.
Composite filter-tip 16 also has the capsule 22 enclosing liquid of the present invention, and this capsule 22 forms general cylindrical shape, is configured between filtering element 18,20.Therefore, capsule 22 has the front end adjacent with filtering element 18 and the rear end adjacent with filtering element 20.These capsules 22 and filtering element 18,20 form composite filter-tip 16 by wrapping into forming paper (not shown).
Before the smoking of above-mentioned cigarette with filter tip 10 or feel elated and exultant between, user can apply external force F via joint paper 14 on capsule 22, is destroyed by capsule 22.Such as, capsule 22 is destroyed in the front end of filtering element 18 side.The destruction of this capsule 22 makes the liquid in capsule 22 spray from the failure position of capsule 22 towards filtering element 18, and the Liquid Penetrant of ejection is in filtering element 18.
Liquid in capsule 22 is water, when the mainstream smoke of cigarette 12 is by filtering element 18, the water soluble ingredient comprised in mainstream smoke is dissolved in the water penetrated in filtering element 18, and the content of the water soluble ingredient in mainstream smoke reduces.Consequently, the local flavor of mainstream smoke and sense of taste change, user can taste local flavor and the sense of taste of change.
On the other hand, as long as in a liquid containing spices, form the fragrance of spices in mainstream smoke, user not only can taste local flavor and the sense of taste of mainstream smoke, can also taste the fragrance of spices.
In addition, to supplement, capsule 22 also can rupture in the rear end of filtering element 20 side.In this situation, when capsule 22 ruptures, the liquid (water) in capsule 22 penetrates in filtering element 20.Like this, much less, liquid (water) also penetrates in filtering element 20, can obtain aforesaid advantage equally.
Various form considered by above-mentioned capsule 22, below, is described the specific embodiment of capsule 22.
Fig. 2 ~ Fig. 4 represents the capsule 22a of the 1st embodiment E 1.
Capsule 22a contains capsule body 24, and this capsule body 24 forms cup-shaped, elastically deformable substantially.Therefore, capsule body 24 has end wall 26 and the openend 28 of the front end forming capsule 22a respectively.
Much less capsule body 24 has configurable size in composite filter-tip 16.Such as, the length of capsule body 24 preferably about 1 ~ 3mm shorter in the length of the cavity 19 guaranteed between filtering element 18,20.In addition, the diameter of capsule body 24 preferably about 0.5 ~ 2mm less of filtering element 18, the 20 i.e. diameter of cavity 19.
In addition, capsule body 24 is not necessarily limited in circular cross section, can have the cross section of elliptical shape.In this situation, maximum gauge about the 0.5 ~ 2mm less of the diameter of cavity 19 of capsule body 24.
More particularly, when the diameter of cigarette 12 is 8mm, the maximum outside diameter of capsule body 24 is such as about 6mm.
As long as capsule body 24 i.e. capsule 22a has above-mentioned size, the then manufacture of not only composite filter-tip 16, namely become easy at capsule 22a to the configuration in filtering element 18,20, and the cognition of user to the capsule 22a in composite filter-tip 16 also becomes easy, in addition, the position of the capsule 22a in cavity 19 and stable posture.
In addition, capsule body 24 synthetic resin injection molded, such as can use the low density polyethylene (LDPE) (Novatec (LD) of Japan Polyethylene Corp.'s property at this synthetic resin.
Capsule body 24 also has perisporium 30.The external diameter of this perisporium 30, internal diameter and thickness reduce from openend 28 a little gradually towards end wall 26.Strictly speaking, perisporium 30 forms cone-shaped.
As can be seen from Figure 2, end wall 26 has the form of recess.Such as, when the 1st embodiment E 1, end wall 26 have ring-type peripheral part 32 and compared with this peripheral part 32 to the central portion 34 of capsule body 24 sunken inside.As can be seen from Figure 3, peripheral part 32 forms the extension of perisporium 30, from central portion 34 to the axis direction of capsule body 24 such as outstanding about 0.8mm.At this, it should be noted that the thickness of the front end of the Thickness Ratio of peripheral part 32 and the adjacent perisporium 30 of peripheral part 32 is thick.
Central portion 34 is not smooth wall, from the outside of capsule body 24, has the cone shape of partially flat former.Therefore, the center of central portion 34 compared with the periphery of central portion 34 slightly to capsule body 24 sunken inside.
Multiple V-shaped valley 36 is formed with as thin-wall regions at the inner face of central portion 34.These V-shaped valleys 36 are around the center radial configuration of central portion 34, and the circumference along capsule body 24 is uniformly distributed.Each V-shaped valley 36 extends to peripheral part 32 from the center of central portion 34.In addition, in Fig. 3, V-shaped valley 36 illustrate only one.
The V word angle of each V-shaped valley 36 is such as 90 °, and the thickness Tv at the end of each V-shaped valley 36 is thinner than the minimum thickness of end wall 26 and perisporium 30, such as, be 0.12mm.If supplemented, the thickness of central portion 34 is such as identical with the thickness of aforesaid peripheral part 32, such as, be 0.3mm again.
The openend 28 of capsule body 24 has flange 38 in its periphery, and the thickness of this flange 38 and external diameter are such as 0.3mm, 6.4mm.
As shown in Figure 3, openend 28 is inaccessible in liquid-tight manner by seal member 40.Sealing parts 40 form the rear end of aforesaid capsule 22a.Such as, seal member 40 is formed by having flexible plate, engages with the flange 38 of openend 28.Like this, as long as seal member 40 has flexibility, seal member 40 would not hinder the elastic deformation of capsule body 24.
More specifically, seal member 40 can be formed by polyamide/low density polyethylene (LDPE) glued board sheet material (TAMAPOLY Co., Ltd. system, NY#15/DL/LC-21,50 μm).In this situation, seal member 40 and flange 38 seal.Like this, as long as seal member 40 and flange 38 seal, then can guarantee that the heat-sealing area between openend 28 and seal member 40 is wider, the sealing intensity of seal member 40 increases.
In addition, capsule body 24 has multiple rib 42, and these ribs 42 form one with the outer peripheral face of capsule body 24.Such as, rib 42 extends from the front end of the peripheral part 32 of end wall 26 to flange 38 along the axis direction of capsule body 24, and has in the circumference of capsule body 24 and exist at equal intervals and configure.To supplement, the thickness of rib 42 is such as about 0.3mm.
The thickness of rib 42 is not certain along the axis direction of capsule body 24, as can be known from Fig. 4, reduces gradually from the front end of flange 38 perimembranous 32 toward the outside.Therefore, the rigidity of the radial direction of capsule body 24 reduces towards end wall 26 along with from flange 38.
Above-mentioned capsule body 24 and seal member 40 form capsule 22a.This capsule 22a can enclose liquid therein.Such as, as the liquid be enclosed, consider distilled water, in this distilled water, be dissolved with the aqueous solution etc. of the additives such as spices.
Such as, capsule 22a accommodates the liquid of 130mg.When capsule 22a is configured in composite filter-tip 16, from the aforesaid explanation of Fig. 1, the filtering element 18 of end wall 26 towards cigarette 12 side is configured in the cavity 19 between filtering element 18,20 by capsule 22a.
According to the cigarette with filter tip 10 possessing capsule 22a, user is before smoking or between feeling elated and exultant, by the capsule 22a of composite filter-tip 16 being sandwiched between finger via joint paper 14, the external force F shown in Fig. 1 can be applied to capsule 22a from the diametric(al) both sides of capsule 22a.
This external force F is damaged by pressure while making capsule body 24 elastic deformation, makes to press liter in capsule 22a.
As mentioned above, the end wall 26 of capsule body 24 possesses peripheral part 32, and this peripheral part 32 surrounds central portion 34 and gives prominence to from central portion 34.Therefore, end wall 26 compares with the smooth end wall not possessing peripheral part 32, has high rigidity.Therefore, when external force F is delivered to end wall 26, end wall 26 as shown in Figure 5, elastic deformation ovalisation.
In this elastic deformation is as Fig. 5 shown in arrow T, apply pulling force at the central portion 34 of end wall 26.Such pulling force T acts on end wall 26 along the major axis being deformed into oval end wall 26, is extended at the end (wire position) of the specific V-shaped valley 36 along aforementioned major axis along the groove direction of this V-shaped valley 36.Consequently, the thickness at the end of specific V-shaped valley 36 especially significantly reduces in the center of central portion 34.
The thickness at the end of so specific V-shaped valley 36 reduces, on the other hand, as mentioned above, if the interior pressure of the capsule 22a risen is applied to end wall 26, then the end of specific V-shaped valley 36, in the center of central portion 34 correctly and easily rupture, and the liquid in capsule 22a sprays from the fracture location of V-shaped valley 36 towards the central authorities of filtering element 18.That is, the destructible of capsule 22a is improved, on the other hand, can the fracture position of specific end wall 26.
As mentioned above, central portion 34 caves in than peripheral part 32, on the other hand, form the cone shape of flat former, and V-shaped valley 36 is formed at the inner face of central portion 34.Therefore, if end wall 26 is deformed into ellipse, central portion 34 is out of shape in the mode of depression further in capsule body 24.The distortion of this central portion 34 makes the groove width of specific V-shaped valley 36 significantly expand, and promotes the fracture of specific V-shaped valley 36, improves the destructible of capsule 22a further.
After V-shaped valley 36 ruptures, if capsule 22a damages by pressure by user further, the liquid in capsule 22a just continues ejection from the fracture location of V-shaped valley 36 towards filtering element 18.Therefore, the Liquid Penetrant of ejection, to the central authorities of filtering element 18, as shown in Figure 1, forms Liquid Penetrant region LA in filtering element 18.This permeable areas LA stays the middle body in filtering element 18, can not bedew forming paper or the joint paper of composite filter-tip 16 from the liquid of capsule 22a ejection.
If described in detail this point, specific V-shaped valley 36 is at its bottom break, and liquid is once from fracture location ejection, then the interior pressure in capsule 22a will sharply reduce.Therefore, after this, fracture location can not expand, and liquid is only from the central authorities of the central portion 34 of fracture location and end wall 26 towards the middle body ejection in filtering element 18.
On the other hand, the finger being sharply decreased through user of above-mentioned interior pressure is by user's perception, and user can confirm the destruction of capsule 22a, i.e. the ejection of liquid.
If liquid is penetrated in filtering element 18, mainstream smoke as above by filtering element 18 time, the water soluble ingredient comprised in mainstream smoke will be dissolved in liquid in filtering element 18 and distilled water.Consequently, the water soluble ingredient in the mainstream smoke of the actual suction of user reduces, so the local flavor of mainstream smoke and the sense of taste change.
On the other hand, if containing spices in liquid, then can with the fragrance of spices in mainstream smoke, user can also taste the fragrance of fragrance simultaneously.
In addition, the situation of the 1st embodiment E 1, the perisporium 30 of capsule body 24 has aforesaid multiple rib 42, although so the rigidity entirety of perisporium 30 is higher, the rigidity of perisporium 30 reduces along with from flange 38 towards the peripheral part 32 of end wall 26.
Therefore, even if capsule body 24 is applied in external force F as shown in Figure 6, the perisporium 30 of capsule body 24 does not also have local dent, and external force F is efficiently transferred the end wall 26 of flat cone shape.Consequently, as aforementioned, end wall 26 is reliably deformed into ellipse, and the specific V-shaped valley 36 as thin-wall regions is easily ruptured by little external force F.
Fig. 7 and Fig. 8 represents the end wall 26c of the capsule 23 of comparative example and the side view of capsule 23 respectively.In this situation, end wall 26c is smooth, and the capsule body 24 of capsule 23 does not possess aforesaid rib 42.
By applying external force F at capsule 23, press when rising in capsule 23, end wall 26c as shown in Figures 7 and 8, evenly bloats towards the outer of capsule 23, can not be deformed into ellipse.
Therefore, do not have the specific V-shaped valley 36 that should rupture, in addition, no matter any V-shaped valley 36 ruptures, and is all not easy fracture herein.
In addition, if capsule 23 does not possess rib 42, then as shown in Figure 8, perisporium 30 because of external force F local be significantly out of shape, external force F is not efficiently transferred end wall 26c, V-shaped valley 36 be difficult to fracture.
The present invention is not restricted by the capsule 22a of the 1st above-mentioned embodiment E 1.
Therefore, for the capsule 22 of other embodiment, next coming in order are described.
In addition, when other embodiment is described, adds identical reference marks at the parts and position playing the function identical with the embodiment illustrated, omit their explanation.
Fig. 9 ~ Figure 11 represents the capsule 22b of the 2nd embodiment E 2.
The perisporium 30 of capsule 22b about capsule body 24 and the structure of end wall 26, and the capsule 22a of the 1st embodiment E 1 is different in the following areas.
First, the perisporium 30 of capsule 22b does not possess aforesaid rib 42.
On the other hand, from whole observation, the end wall 26 of capsule 22b also forms recess.But the situation of capsule 22b, the peripheral part 32 of the circle of end wall 26 extends towards the radially inner side of capsule body 24.In addition, the central portion 34 of end wall 26 is formed in hemispherical portion 44, and this hemispherical portion 44 is towards capsule body 24 sunken inside.
In addition, the central authorities in hemispherical portion 44 are formed as circular thin-wall regions 46, and this thin-wall regions 46 has than the end wall 26 of capsule body 24 and the thin thickness of the thickness of perisporium 30.Such as, the thickness Tc of thin-wall regions 46 is such as identical with the thickness Tv at the end of aforesaid V-shaped valley 36.
Hemispherical portion 44 is included in the annulus 47 surrounding thin-wall regions 46 between peripheral part 32 and thin-wall regions 46.This annulus 47 has from thin-wall regions 46 along with the thickness increased gradually close to peripheral part 32, is connected with the angle of the inner side of peripheral part 32.
As can be seen from Figure 10, the thickness of the periphery of the Thickness Ratio annulus 47 of peripheral part 32 is thick.On the other hand, the thickness of perisporium 30 is certain along the axis direction of capsule body 24, and thicker than the maximum thickness of the perisporium 30 of the capsule 22a of embodiment E 1.
The situation of the capsule 22b of the above embodiments E2, also when capsule body 24 applies external force F, the oval elastic deformation of end wall 26 of capsule body 24.Therefore, significantly stretch along the specific wire position of the thin-wall regions 46 of the major axis of the end wall 26 of elliptical shape distortion, consequently, end wall 26 ruptures at specific wire position.
Figure 12 and Figure 13 represents the capsule 22c of the 3rd embodiment E 3, Figure 14 and Figure 15 represents the capsule 22d of the 4th embodiment E 4.
Capsule 22c, 22d of 3rd and the 4th embodiment E 3, E4 are similar with capsule 22a, 22b of the 1st and the 2nd embodiment E 1, E2 respectively.But capsule 22c, 22d are also possessing bar-shaped projection 48 respectively, this point and capsule 22a, 22b different.
In detail, the situation of the capsule 22c of the 3rd embodiment E 3, protruding outside from the center of the central portion 34 of end wall 26 towards capsule body 24 of projection 48.On the other hand, when the capsule 22d of the 4th embodiment E 4, protruding outside from the central authorities in hemispherical portion 44 and thin-wall regions 46 towards capsule body 24 of projection 48.
No matter be the 3rd and the 4th embodiment E 3, which kind of situation of E4, from Figure 13 and Figure 15, the front end face of projection 48 and the outer face of end wall 26 (peripheral part 32) are positioned in identical imaginary plane.In addition, the diameter of projection 48 and length are such as about 0.4 ~ 0.5mm.
Above-mentioned projection 48, when V-shaped valley 36 or thin-wall regions 46 rupture, determines that fracture position aspect works.Specifically, capsule body 24 applies external force F, when the specific wire position of specific V-shaped valley 36 or thin-wall regions 46 is stretched, tension concentrates on the root of projection 48.Consequently, projection 48 becomes the starting point of fracture, determines fracture position.In addition, projection 48 can not protruding outside from end wall 26 to capsule 22, so be difficult to apply undesirable impact in projection 48, in addition, due to this impact, the possibility that end wall 26 undesirably ruptures from the root of projection 48 is also low.
Figure 14 represents the capsule 22a ~ 22d applying external force F at the 1st ~ 4th embodiment E 1 ~ E4, measures the result of these capsules 22a ~ 22d at the mean value of the fracture load of the capsule 22a ~ 22d in the moment that V-shaped valley 36 or thin-wall regions 46 rupture respectively.In addition, Figure 14 represents the measurement result of the mean value of the fracture load of the capsule of comparative example C and reference example R in the lump.
When measuring fracture load, in each capsule, filling the liquid (distilled water) accounting for 94% of volume, using creep device (Yama Co., Ltd.'s electricity system, RHEONER II (trade name)) when measuring fracture load.
Before the measurement result mentioning Figure 14, the capsule of comparative example C and reference example R is described simply.
The capsule of comparative example C is equivalent to the capsule of aforementioned patent literature 1, and the capsule of reference example R is equivalent to the Sealmess capsule loading commercially available cigarette with filter tip.
As can be seen from Figure 14, the fracture load of the capsule 22a ~ 22d of the 1st ~ 4th embodiment E 1 ~ E4 is significantly less than the fracture load of the capsule of comparative example C, in addition, close to the fracture load of the capsule of reference example R.Therefore, understand that the capsule 22a ~ 22d of the 1st ~ 4th embodiment E 1 ~ E4 is easier than the capsule of comparative example C to rupture.
In addition, when contrasting capsule 22a, 22c of the 1st and the 3rd embodiment of same types, the fracture load of capsule 22c is less than the fracture load of capsule 22a.In addition, equally, when contrasting capsule 22b, 22d of the 2nd and the 4th embodiment of same types, the fracture load of capsule 22d is less than the fracture load of capsule 22b.
This things to know ground represents that aforementioned projection 48 not only determines the fracture position at end wall 26, and makes the fracture of capsule 22c, 22d become easier.
Finally, the present invention also can not restrict by aforementioned 1st ~ 4th embodiment E 1 ~ E4.
Such as, previous embodiment capsule body 24 and all formed by low density polyethylene (LDPE) as the seal member 40 of closure wall.But capsule body of the present invention and closure wall also can be formed by the synthetic resin beyond low density polyethylene (LDPE), in addition, also can be formed by other material beyond synthetic resin.
Such as, the capsule body 24 of the 1st embodiment E 1 has the perisporium 30 formed towards the tapered cone-shaped of end wall 26.But in situation of the present invention, capsule body also can have the perisporium forming straight drum or reverse cone-shaped.
In addition, the end wall of capsule body of the present invention also can be the recess of the form different from the end wall 26 of aforesaid 1st ~ 4th embodiment.Such as, in the situation of the 1st and the 3rd embodiment E 1, E3, end wall 26 also can have smooth central portion 34.
In addition, when the 2nd and the 4th embodiment, whole region, hemispherical portion 44 also can be formed as thin-wall regions, and in the situation of the 1st and the 2nd embodiment, thin-wall regions also can be formed as the groove of the shape had beyond V-shaped.In addition, the configuration of these grooves is also not limited to radial.
Thin-wall regions thickness by than the end wall of capsule body and the thickness of perisporium thin premised on, preferred more than 0.1mm and be less than 0.2mm.More preferably the thickness of thin-wall regions is more than 0.12mm and is less than 0.17mm.
Such as, the capsule body 24 of the 1st and the 3rd embodiment E 1, E3, has multiple rib 42 at its outer peripheral face.But these ribs 42 can be arranged at the inner peripheral surface of capsule body 24, in addition, this rib 42 equally also goes for the 2nd and the 4th embodiment E 2, the outer peripheral face of capsule body 24 of E4 or inner peripheral surface.
