Definitions
- the invention relates to a ventilated multifilter for a Rauchartikei with at least two filter segments, wherein at least one filter segment comprises a component to be dispensed to the smoke component and at least one further filter segment comprises a sorbent, which receives at least one component of the smoke stream, and at least one Fiitersegment at least one recess having the peripheral surface
- cigarette filters which are provided, for example, with activated charcoal particles, which absorb unwanted substances from the cigarette smoke. It is also possible that certain substances desired in cigarette smoke, such as flavorings, are disadvantageously removed from the cigarette smoke. This can negatively affect the taste of the cigarette.
- the smoking article filter according to the invention has at least two filter segments.
- the first filter segment comprises a component which is discharged to a passing through a filter outlet smoke stream
- a second filter segment comprises a sorbent, which receives at least one component from a passing through the filter inlet opening smoke stream.
- the term "ingestion” is understood to mean both the adsorption of the component on the sorbent (adsorption) and the absorption of the component in the sorbent (absorption). In the broadest sense, any binding of the component to be removed by the sorbent should be referred to as "uptake”.
- a filter segment is thus mixed with a sorbent or a substance, so that one or more undesired components are completely or partially removed or "filtered out” from the smoke stream.
- desired components or substances such as flavorings
- the filter according to the invention comprises a further segment with one or more components, which is delivered to the smoke stream or the smoke stream is or will be.
- flavorings which are removed together with the undesired components from the smoke stream can be added back to the smoke stream later, in order not to adversely affect the original taste of the smoking article.
- the filter according to the invention comprises several segments, all one or more identical substances or different substances deliver the smoke stream. It is also conceivable that the filter according to the invention comprises a plurality of segments which "filter out" one, several or respectively different unwanted components from the smoke stream. So the number of segments is not limited to two segments, but may well have several identical or different segments, each of which absorb substances from the smoke stream or deliver to this.
- the filter comprises two filter segments, the first being a fitter segment comprising a component to be delivered to the smoke stream and the second a filter segment comprising a sorbent capable of receiving one or more components from the smoke stream.
- the first filter segment is intended to be arranged in a region of the filter facing away from the smokable material, that is to say from the tobacco rod, while the second filter segment is arranged in a region of the filter facing the smokable material of the smoking article.
- the second filter segment is arranged between the tobacco rod and the first filter segment.
- the smoke stream coming from the smokable material is first passed through the second filter segment and cleaned of unwanted components, the smoke stream then passing through the first filter segment where it is subsequently spiked with a desired component before ultimately exiting the smoking article.
- the reverse case is also conceivable, namely that the unfiltered smoke stream is first mixed with a component to be added and only then unwanted components are removed from the smoke stream.
- the sorption medium receiving the undesired components can accommodate only a certain proportion of desired components of the smoke flow in the second filter segment, so that after filtering the smoke flow still a sufficiently high proportion of one or more desired components of the smoke flow is present.
- the first filter segment that is to say the filter segment comprising the component to be supplied, has one or more recesses. These recesses may serve to guide venilatory air and may be evenly distributed on the outer circumference of the first filter segment and may be located parallel to the longitudinal axis of the first filter segment extend. It is also conceivable that the recesses on the outer circumference of the first filter segment extend slightly helically. It is also conceivable that the second filter segment also has such recesses, that is, the recesses extend over both filter segments.
- the recesses may be in the form of grooves on the outer circumference of the filter and preferably extend from the smoker facing the end of the filter or the filter outlet opening into the filter, in particular up to a region in the first filter segment.
- the first filter segment comprises a region or an element with a component to be delivered to the smoke stream.
- the first filter segment may be impregnated with the component to be dispensed or the component to be dispensed may be distributed over at least a portion of the first filter segment.
- the first filter segment comprises a stretched element arranged on the central longitudinal axis of the first filter segment and comprising the component to be dispensed.
- this may be a so-called Fiavourfaden that has been treated with a Flavoursubstanz.
- the present in the Fiavourfaden substances are delivered to the smoke stream.
- the recesses fulfill, in particular at the periphery of the first filter segment, a further function, namely the concentration of the smoke flow towards the fi ve thread, so that the substances to be dispensed can be delivered as well as possible to the smoke flow.
- the sorbent in the second FHtersegment an adsorbent !,
- the activated carbon may be distributed granularly or particulate over the entire second filter segment.
- both the first and the second filter segment each comprise a filter base element and a base covering, while the filter base elements are produced from cellulose acetate tow and are each provided at their circumference with an envelope, for example a paper material.
- the envelopes may be bonded to the filter bases after the filter bases have been swept one after the other in accordance with a desired arrangement.
- a further filter wrapper be arranged, in particular glued.
- a dimensionally stable enclosure of the filter can be achieved by these Umhüilept, wherein in the region of the filter segment with the recesses or grooves on the outer circumference a dimensionally stable enclosure is desired to a permanent Formstabiitician the recesses or grooves in the first Safe filter section.
- a dimensionally stable enclosure of the filter is a planar shift of the Grundumhüllungen with the Fiiterground instituten, as well as a surface bonding of the filter wrap with the Grundumhüliache.
- the Kiebeinformation between the sheaths and the Fiiterground instituten after curing forms a dimensionally stable envelope of the filter. It is advantageous if the bonds extend over a large area over the circumference of the filter segments. In a preferred case, the bonds extend over 80% to 95% of the circumferential area of the filter segments or the filter.
- the mass of the amount of adhesive used to bond the filter base segments to the base and filter wraps can range from 5% to 15% of the total mass of the filter.
- a particularly dimensionally stable enclosure of the filter base segments is achieved, which ultimately leads to a very dimensionally stable filter. It is also conceivable that only in the region of the first filter segment or in the region of the recesses or grooves a high dimensional stability is formed, while the rest of the filter has a lower or comparable with conventional filters dimensional stability.
- the invention further relates to a method for producing a filter for smoking articles.
- a first filter base element is provided with a component to be dispensed to the smoke stream.
- this takes place by incorporating a component comprising the component to be dispensed, for example a flavor thread on the filter base element.
- a base cladding can be applied or glued around the first filter base element, which extends over the peripheral surface of the filter base element, whereby a first filter segment is produced.
- the inventive method comprises at which a second filter base member having a Sorptionsmitte !, activated carbon is provided, in particular, so that at least one undesirable component is absorbed by this sorbent or, particularly adsorbed in the finished filter of the smoking article in the area of the second filter base element a further step ".
- the second filter segment may be provided with activated carbon particles, which are distributed, in particular distributed uniformly arranged in the second filter segment.
- This second filter segment like the first filter segment, can then be glued circumferentially to a base wrap.
- the first and second filter segments can be glued to a common filter envelope, in particular adhesively bonded over a large area, and thus combined to form a filter.
- a common filter envelope in particular adhesively bonded over a large area
- a generous order of adhesive or glue for the dimensional stability of the filter wrapper is beneficial compared to conventional filter production.
- the filter thus connected can be provided with recesses or grooves in the region of the mouth-side filter segment are, for example, evenly distributed on the circumference of the filter segment and extending parallel to a longitudinal axis of the filter.
- These grooves can be done, for example, by rolling the entire filter over a controllably heated plate under a controllable contact pressure, wherein the plate has projections in a desired geometry, which impress in the filter material.
- a plurality of filter segments can be placed one behind the other to form a so-called filter rod, which can ultimately be divided into a plurality of individual multr filters.
- the entire filter rod is rolled over a controllably heated plate to form the recesses or grooves, wherein at certain intervals the recesses or grooves are formed on the filter rod, so that after dividing the filter rod into individual multifilter the grooves are formed at certain desired locations of each individual Multiphilter.
- the gluing or gluing of the base wrapper and / or the filter wrapper can take place in terms of area, wherein a small area preferably remains free for gluing the seam of the filter wrapper paper with another glue.
- This so-treated filter can then cure for up to 90 hours, such that a higher filter hardness, especially as a result of higher triacetin coverage in the grooved filter segments, can range from 7% to 15% of the total mass of the filter in this filter segment compared to a standard fiber hardness is reached.
- the filters are cut to length in a known manner and joined to the wrapped tobacco rod by a tipping paper.
- the tipping paper is ventilated in a known manner or can be ventilated in a known manner during cigarette production.
- FIG. 1 shows a filter according to the invention for a Rauchartikei, which is provided overall with the reference numeral 1.
