Abstract
The present invention provides a tobacco smoke filter or filter element having a fixed length comprising a wrapper (5) engaged around a downstream core (1) of tobacco smoke filtering material and a further core (2) longitudinally aligned therewith; wherein the further core is reversibly moveable relative to the wrapper along the longitudinal axis of the filter.
Description
Technical field
The present invention relates to such as tobacco smog filte r and the filter cell of the smoking product of such as cigarette.
Background technology
Smoker can the adjusted filter concept that changes the cigarette of the band filter of smoking experience be known.Such as, smoker can break breakable capsule in filter to discharge fragrance, or by the different paths transfer smog such as containing different filter or aroma materials or air.Many concepts in these concepts are by enabling the modified filter ventilation level of smoker, and the intensity or the concentration that change the smog of suction thus perform.A this example is disclosed in US 4646763.This filter is used in the brand ' Concord ' of Philip Morris.This product is all operated by pivoting mechanism together with many designs of adjustment ventilation level, and in this pivoting mechanism, smoker makes a filter component rotation and other parts keep static.
Also be known by the adjustable filtering device vertically moving operation of being initiated by smoker.An example is disclosed in the GB 2194427 transferring Cigarette Components Ltd (cigarette component Co., Ltd).In the product, there is central filter element, this central filter element can move align with external ventilation sleeve or do not line up, thus ventilation level is changed.This product additionally uses the coaxial filter cell of mouth end, and in the coaxial filter cell of this mouth end, center core does not adhere to the endless belt of surrounding.In operation, smoker promotes the center core of mouth end component, and this makes central filter element move (to be similar to the mode of piston rod driven plunger) thus not line up with air vent conversely, thereby increases ventilation level.But, there is many shortcomings in this product: the position of (a) movable central parts can such as during transportation unexpectedly change, therefore smoke characteristics can not as was expected, and block therefore smoker due to internal ramp structure by opaque forming paper (plugwrap paper)/cork paper (tipping paper) and can not notice this point; B () regulates is irreversible, and namely making after central member moves by means of center core, if smoker wishes to readjust product, then this central member can not return its initial position; C () downstream core can such as by vibrating or chewing and be unexpectedly ejected filter on the filter; And (d) this product requirement consumer rational flexibility ratio in use.
Earlyly, disclose WO 2011/121325 and WO 2011/121327 (BAT), both discusses numerous concepts of adjustable filter in a longitudinal direction.But filter will tend to change due to adjustment relative to plume these necessary mobile (that is, whole length of smoking product).
Summary of the invention
The invention provides a kind of cigarette of adjustable band filter, which overcome aforesaid drawbacks of the prior art.The level regulated is visible (may be maybe visible) for smoker; Adjustment is reversible; There is not the casual ejection of filter component; Use simple; And there is not the change of filter length or the cigarette length caused because of adjustment.In addition, the cigarette of filter/filter cell/band filter of the present invention uses conventional cigarette filter material and manufacturing technology directly to be assembled.
According to the present invention, provide a kind of there is regular length tobacco smog filte r or filter cell (namely, the filter of regular length or filter cell), the downstream comprised around tobacco smoke filtration material is (such as extending longitudinally, such as roughly in cylindricality) packing material (such as outer wrapper) that engages of core, and with this downstream core longitudinally aim at other (such as extending longitudinally, such as roughly in cylindricality) core (such as tobacco smoke filtration material), wherein, this other core reversibly can to move along the longitudinal axis (such as upper and lower) of filter relative to packing material and (such as can reversibly regulate, can reversibly slide).
Preferably, packing material (such as outer wrapper) comprises aerated area.Preferably, packing material (such as outer wrapper) comprises aerated area, and this aerated area comprises at least one ring (ring) or the endless belt (annulus) of the air vent of the periphery around filter/filter cell.
Packing material (such as outer wrapper) is preferably transparent, as discussed below.
This other core can reversibly move (such as reversibly can regulate, can reversibly slide) in the two directions along the longitudinal axis of filter.This other core can this other core align with one or described aerated area (such as stop and align) or the position of partly align (such as stop and align) do not align with one or described aerated area with this other core (such as stop and align) position between reversibly move (can move around).This means that smoker by sliding other core and reversibly regulate other core to make it not stop ventilation along the longitudinal axis of filter, or can partly or wholly stop ventilation, and change thus and ventilate and therefore change smoking experience.
According to the present invention, in one aspect, provide a kind of tobacco smog filte r or filter cell, comprising:
Downstream (such as extending longitudinally, such as, roughly in the cylindricality) core of tobacco smoke filtration material;
With upstream (such as extending longitudinally, such as, roughly in the cylindricality) core of downstream core longitudinally (upstream) isolated tobacco smoke filtration material;
Packing material (such as outer wrapper), it engages around isolated upstream core and downstream core, and connects isolated upstream core and downstream core; And
Other (such as extending longitudinally, such as, roughly in the cylindricality) core (such as tobacco smoke filtration material) longitudinally aimed between downstream core with upstream core and with downstream core and upstream core;
Wherein, other core can reversibly move (such as reversibly can regulate, can reversibly slide) along the longitudinal axis (such as relative to packing material) (such as, in such as upper and lower both direction) between isolated upstream core and downstream core of filter.
Other core such as can be moved (such as reversibly can move, can reversibly regulate, can reversibly slide) in such as outer wrapper promotion or pinching by (smoker) in the mode being similar to ejection self-control cigarette (Roll-Your-Own) filter cell from ' Pop-a-Tip ' product as in known in the art.
Preferably, tobacco smog filte r or filter cell have fixing length (that is, being filter or the filter cell of regular length).
In this article, term " downstream " means the one end towards the oral area of the smoker of the cigarette of the closest filter of the cigarette of filter/filter cell/band filter (such as, when filter/filter cell is attached to the tobacco shell in the cigarette of band filter).Term " upstream " means the one end towards the tobacco shell of the cigarette of the closest filter of filter/filter cell (such as, when filter/filter cell is attached to the tobacco shell in the cigarette of band filter).In this article, it is fixing that term " regular length " and " filter of regular length or filter cell " mean that filter/filter cell (and the cigarette such as with filter that is attached to of filter/filter cell and so on any smoking product) has along the longitudinal axis, that is, the end-to-end measurement (length) of (such as when such as by making other core move during adjusted filter) can not be changed.Herein, term " reversibly " (appearing in " can reversibly move ", " can reversibly regulate ", " can reversibly slide ") means once be moved, slide or regulate, then other core can be moved again (slide, regulate), make it can return its initial position (such as, if smoker wishes again again to regulate product, if or it has shifted out position for some reason, then it can have been retracted its initial position).
Preferably, filter or filter cell comprise the aerated area (such as comprising air vent) between isolated upstream core and downstream core.Preferably, aerated area is arranged towards upstream core or towards downstream core.Preferably, aerated area comprises at least one ring or the endless belt (between isolated upstream core and downstream core) of the air vent of the periphery around filter/filter cell.Preferably, packing material (such as outer wrapper) comprises aerated area.Preferably, packing material (such as outer wrapper) comprises aerated area, and this aerated area comprises at least one ring or the endless belt of the air vent of the periphery around the filter/filter cell between isolated upstream core and downstream core.
Other core along filter the longitudinal axis in the two directions (between isolated upstream core and downstream core) can reversibly move (such as reversibly can regulate, can reversibly slide).Other core can this other core align with one or described aerated area (such as stop and align) or the position of partly align (such as stop and align) do not align with one or described aerated area with this other core (such as stop and align) position between reversibly move (can move around).This means that smoker reversibly can regulate this other core that it is not stopped by making other core slide between isolated upstream core and downstream core and ventilates or partly or wholly stop ventilation, and change ventilation thus and therefore change smoking experience.
Preferably, packing material (such as outer wrapper) is transparent.Should be understood that, transparent packing material (such as outer wrapper) has following advantage, that is: smoker clearly can see the position of other (removable) core of tobacco smoke filtration material relative to aerated area (and isolated upstream core and downstream core).Packing material (such as outer wrapper) can be formed by any suitable transparent material.Packing material (such as outer wrapper) can be such as oriented polypropylene (OPP), bi-oriented polypropylene or glassine paper.Optimization polypropylene, because polypropylene tends to become harder and is not easy to shrink during heat treatment process.Preferably, packing material (such as outer wrapper) is flexible, it is retained after is has been compressed or substantially retains its original-shape.Should be understood that, (such as packing material can be paper can to use nontransparent packing material (such as outer wrapper) according to the present invention, such as, forming paper), although can see with smoker the benefit that movably other core is associated by losing.
Upstream core and/or downstream core can be adhered to packing material (such as outer wrapper).Preferably, upstream core and downstream core are such as adhered to packing material by adhesive.Preferably, adhesive is hotmelt or emulsion-based (such as, EVA, PVA or PVOH) adhesive.Adhesive is used by spraying system.In adhesive is preferably arranged on (such as ad hoc) regional area or multiple regional area (such as, with discrete block or part).Adhesive is preferably arranged on (such as, ad hoc) to be positioned in a regional area between packing material and downstream core and/or upstream core (if existence) or multiple regional area (such as, with discrete block or part).Preferably, the inner surface in the region between isolated upstream core and downstream core of packing material do not exist adhesive (lengthwise movement relative to packing material of therefore, the other core adhesive not on packed article hindered).
Preferably, this other core (such as extending longitudinally, such as, roughly in cylindricality) comprises tobacco smoke filtration material.
Downstream filter core, other filtration core and upstream filtering core (if existence) can comprise tobacco smoke filtration material.Tobacco smoke filtration material for described core can be identical or different.Tobacco smoke filtration material can be such as be generally used for any material (being generally material that is filamentous, fibrous, netted or that extrude) in those materials of tobacco smog filte r manufacture.Filtering material can be filamentary tow that is natural or synthesis, such as, and cotton or plastics (as polyethylene or polypropylene), or cellulose acetate filamentary tow.Filtering material such as can be the short fiber of natural or synthesis, raw cotton (cotton wool), Web materials as the non-woven fabric of paper (normally wrinkling) and (such as synthesizing) and extruded material (such as starch, synthetic foam, exruded foams).Filtering material can be cellulose acetate.
Downstream filter core, other filtration core and upstream filtering core (if existence) can comprise the core packing material engaged around (such as extending longitudinally, roughly in cylindricality) core separately.Packing material can be paper, such as forming paper.
