Description
Technical field
The present invention relates to a kind of tobacco product including filter.
Background technology
Tobacco product, such as cigarette, generally include the tobacco or other being wrapped in inflammable outer packing (being typically cigarette paper)
Suspended particulate forms the rod of material, and the filter to align with the tobacco rod with end-to-end relation.The filter can be with
Include the bar of at least one cellulose acetate tow, the cellulose acetate tow is by being covered in the phase of filter and tobacco rod
Tipping paper in neighboring terminal portion (filter against end) is attached to tobacco rod or other suspended particulates are formed on material.May be used also
To be arranged through the perforation of tipping paper in the filter, filter is passed through with the smog for allowing consumer to be aspirated in smoking.
Nowadays consumer wishes to obtain from any consumer goods product with best quality as far as possible as best as possible
Consumer experience, and they increasingly pay close attention to the perceived quality of displaying and the look and feel of product, this sometimes with its
Its feature is equally important, such as the taste or functional benefits of product.As for any other consumer goods product, this is suitable for cigarette system
Product, consumer judge that a special focus area of the quality of tobacco product is that consumer incites somebody to action with during consumption before consumption
When it is maintained in hand and mouth, the visual appearance and physical behavio(u)r of the tobacco product.
Especially, consumer wishes, tobacco product presents uniform close in tobacco or other suspended particulates generation material bar
Degree and filter, and sizable rigidity or hardness of the filter when being held between finger or lip, are filtered at the same time
The highly uniform circular shape of device and tobacco product as a whole.The appropriate hardness of filter for by filter to finger
The perception that the resistance of crushing strength between lip provides the consumer with high-quality is especially important.Meanwhile hardness cannot be too
Height, to keep certain pliability in mouth and make consumer comfortable during use.Filter and tobacco product it is regular, uniform
Circularity it is also critically important for perceived quality because non-uniform shape gives people to leave the relatively low impression of product quality.
Have it is a variety of influence tobacco product filters hardness and circularity factor, including cellulose acetate tow weight,
Content of plasticizing agent and filter overwrap quality (base weight, thickness, porosity).Need suitably to adjust all of these factors taken together, with
Appropriate hardness is provided and circularity is horizontal, while meets that the expected of product feels and taste target.Especially, only increase is used for structure
Into the amount of the plasticiser (such as triacetyl glycerine) of cellulose acetate filter bar come increase its hardness will be it is effective, still
It is unfavorable for the taste neutral of product.In fact, in higher concentrations, triacetyl glycerine tends to be degraded into acetic acid, and consumer can
The acetic acid is felt and smelt in tobacco product.
The prior art have attempted to by substantially using such as WO 2015007399 A1, WO 2015007400 A1 and
Thicker filter rod outer packing disclosed in 2015007401 A1 of WO increases the hardness of filter.Those files disclose
Tobacco product including tobacco rod and filter, the filter have the mistake for extending to most downstream end (the also referred to as mouth end of filter)
The bar of filter material material, this are surrounded by one or more filters outer packing；Tipping material is attached to tobacco rod and filter.This one
A or multiple filter overwraps have the base weight between about 50 grams every square metre and about 100 grams every square metre, thus reach
The hardness of the filter arrived is at least 90%.
Above-cited patent application, which substantially proposes to use, to be had between about 50 grams every square metre and about 100 grams every square
Thick filter overwrap between rice, such as known in the art be used to manufacturing concave type filter and (such as see WO 2011/
117584 A1).Due to the higher base weight and thickness of filter overwrap, realized as desired using concave type filter
As, this adds the resistance crushed at the mouth end of filter, the acetic acid at the mouth end by extending to filter really in fact
Cellulose further increases the resistance.
However, the filter structure of this filter overwrap with thick, big base weight particularly exists with multiple shortcomings
In terms of manufacture and cost.In fact, with the filtering for the standard filter outer packing between 20 and 30 grams every square metre
The datum speed of device manufacture machine is compared, using with the base between about 50 grams every square metre and about 100 grams every square metre
The thick filter overwrap of weight needs the significant deceleration of up to 25-30%.During brand switching, it is also necessary to adjust filter
Manufacturing machine, or must even change specific machine parts, reduce productivity and increase production cost.
Due to the dust produced during processing, also need to more frequently clean filter using thicker filter overwrap
Manufacturing machine, this also has a negative impact production efficiency and cost.Finally, thick filter overwrap shows more relatively thin than standard
Filter overwrap smaller elasticity, when filter overwrap is wrapped in around the cellulose acetate bar of filter, due to
The intrinsic rigidity of outer packing, produces more non-round filter.
Therefore the tobacco product with another filter structure, compared with the above-described prior art, the filter are needed
Construction shows increased hardness and uniform circularity at the same time, to increase the perception of the quality of consumer, and to manufacturing speed and
There are limited influence (if present) for cost.
The object of the present invention is to provide a kind of improved tobacco product, which includes the filter for solving above-mentioned needs.

DD60A tests ((are manufactured by German Heinr.Borgwaldt GmbH and are realized and is commercial) dress using known DD60A densitometers
Put) obtained hardness measurement.
As the term " hardness " used in disclosure full text characterizes deformation resistance.Hardness number is usually as a percentage.
Fig. 1 shows in the cigarette 100 applied before loading F and applies the same cigarette 110 when loading F, which includes filtering
Device outer packing 102 and tipping material 101.There is diameter D in the cigarette 100 applied before loading FS.Reached applying setting load
After the setting duration (but still applying load), cigarette 110 has (reduction) diameter DF.Diameter reduction (r) is r
=DS-DF.With reference to figure 1, hardness is defined as follows：
Wherein, DSIt is initial (the not reducing) diameter of cigarette, DFIt is after applying setting load and reaching the setting duration
Reduction diameter.Material is harder, and hardness is closer to 100%.
As described in more detail below and commonly known in the art, in order to determine a part (example of tobacco product
Such as filter) hardness, tobacco product should be arranged in parallel within a plane, and the same section to be tested of each tobacco product should be through
The setting duration is reached by setting load.Using known DD60A density counter device (by German Heinr.Borgwaldt GmbH
Manufacture and realization are commercial) test is carried out, which is fitted with measurement head and cigarette container for cigarette.
Apply cylindrical bar using two loads and apply load, which extends through the diameter of whole tobacco products at the same time.According to
The standard method of test of the instrument, test should be performed as so that be produced between tobacco product and load apply cylindrical bar
20 contact points.In some cases, filter to be tested can long enough so that only needs 10 tobacco products to form 20
Contact point, each tobacco product contact two loads and apply rods (because their long enoughs to extend between rod).In other situations
Under, it is too short if filter and can not realize in this way, if should form 20 contact points, each cigarette system using 20 tobacco products
Product only contact a load and apply rod, as discussed further below.
Two other static cylindrical bars are located at below tobacco product, are applied with supporting tobacco product and offsetting by each load
The load that cylindrical bar applies.This arrangement is described in more detail below, as shown in Figures 2 to 4, it is represented as example in WO
The arrangement of the known prior art disclosed in 2015/007401 A1 of 2015/007400 A1 and WO.
For the S.O.P. of this equipment, apply the total load of 2kg up to the duration of 20 seconds.Passing through 20 seconds
(still loaded after clock to tobacco product application), determine that load applies the diameter reduction (r) in cylindrical bar, then using should
Diameter reduction (r) calculates hardness from the equation above.Temperature is maintained in the range of 22 DEG C ± 2 DEG C.Above-mentioned test is referred to as
DD60A is tested.DD60A tests and corresponding equipment is more fully described with reference to Fig. 2 to 4.As discussed in more detail below,
When tobacco product be sucked with it is non-be not sucked when, the hardness of the filter-portion of tobacco product does not have a great difference.However, measured
The standard mode of filter hardness is when tobacco product is not sucked.
, can be with the hardness of the tobacco product of any position measurement of filter when being attached to tobacco rod by tipping material
Between about 85% and about 95%.
In one embodiment of the invention, when being attached to by tipping material in tobacco rod, in any of filter
The hardness of the tobacco product of position measurement is less than about 90% but greater than about 85%；For example, hardness between about 86% to about 88% it
Between in the range of.
Inventor is enjoyably had found by the consumer research and the experiment of various filtration device structures, with available standard mistake
Filter cigarette (has the filter included between about 20 grams of filter overwraps between every square metre and 30 grams every square metre
Cigarette) compare, when only hardness number reaches 85% and the above, consumer can actually feel in its finger and lip
On filter hardness increase, this allows for about the 4 to 6% of about 85% hardness and filter tow material weight
Standard content of plasticizing agent.The more interesting research carried out by inventor shows that consumer does not feel as filter substantially
The increase of more than 90% hardness, and compared with only there is the filter of the hardness between 85% and 90%, certainly not
It may feel that the filter with more than 90% hardness with the quality improved.
Showing the tobacco product of the hardness of 90% or higher needs using the thicker of at least 50 grams every square metre or bigger
Filter overwrap and/or the plasticiser that high level is used in filter tow material, this is with disadvantages mentioned above.However,
Thicker tipping material and at least 50 grams every square metre or thicker filter overwrap with higher content of plasticizing agent
Combination shows the hardness higher than 90%, while mitigates its shortcoming.
