Description

Technical field

The present invention relates, inter alia, to an additive containing element.

State of the art

Filter elements for smoking articles, such as cigarettes, typically comprise an insert of cellulose acetate material surrounded by filter wrapping paper. In the manufacture of cigarettes, filter elements are combined with cigarette sticks and wrapped in yet another wrapper, the so-called “rim paper” that connects them.

It is known to use destructible capsules containing menthol placed inside a filter insert of a cigarette filter. By applying external pressure to the filter, the smoker can break the capsule, thereby releasing flavoring to give flavor to the smoke absorbed from the cigarette.

WO 2010/003899 describes a method of manufacturing a filter rod of a cigarette containing capsules, in which an extended tube containing a plurality of capsules is pulled from a bobbin into a bundle of filter material to form an extended filter rod, which is then cut into segments to form separate filters - sticks containing capsules.

However, it is often desirable to have a more controlled release and location of supplementation than similar capsule systems.

Description of the invention

In FIG. 1 shows a tape 1 having a plurality of additive-containing elements in the form of sealed pockets 2 with regions of reduced strength spaced at intervals along its length. Each pocket 2 has an interior space containing an additive. The tape and pockets may be formed from an elastic polymer material, for example polyvinyl alcohol (LAN) or polyethylene (PE).

As shown in FIG. 2, the cut section 1a of tape 1 can be placed inside the cellulose acetate insert of filter 3 of cigarette 4. Applying outside pressure to filter 3, the smoker can cause pocket 2 to rupture to release the additive contained therein. In this way, the smoker can selectively flavor the smoke sucked out of the cigarette 4.

Tape 1 has an angular region 5 of reduced strength from one end of pocket 2. As the example shown in FIG. 3, the pocket erupts in the corner region 5 with reduced strength when pressure exerts outside the filter 3. In the embodiment shown in FIG. In an example 3, the pocket contains a smoke modifier (for example, water, triacetin or a flavor), and the reduced strength corner region 5 is configured to direct the smoke modifier toward the cigarette stick of cigarette 4. This is especially important in filters where the smoke flow rate is lower near the tobacco end compared with the mouthpiece end, which may be the case if there are ventilation holes near the mouth end. In this case, by directing the smoke modifier to the mouthpiece end, it is possible to increase the interaction time between the smoke modifier and smoke.

Alternatively, as shown in FIG. 4, each pocket 2 may have an angular region 5 with reduced strength from the mouth end of the pocket, and not from the tobacco end. In the example of FIG. 4, pocket 2 contains a smoke modifier in the form of a flavor. In this case, pocket 2 of FIG. 4 is configured to direct flavoring to the mouthpiece end of cigarette 4. This is achieved by releasing flavoring near the mouthpiece end to maximize flavoring.

For the manufacture of tape 1 can be used the method of horizontal or vertical molding, filling and sealing. Tape 1 can be formed of two or more polymer layers hermetically connected to each other so that zones not connected to each other form pockets 2. Heat sealing, ultrasonic welding, water-activated adhesive, or any other suitable process can be used to form tight joints. .

Corner areas 5 of the tape 1 having reduced strength can be obtained by a modified method of vertical molding, filling and sealing. In particular, the tight joint pitch can be modified to obtain a pocket 2 with a transverse edge forming an acute angle with the longitudinal axis of the filter 3, to create an angular region 5 with reduced strength.

The manufacturing method of the tape 1 is illustrated in FIG. 5.

In step A, cavities are formed in the first layer 6. In this case, the first layer 6 is shaped by a vacuum (not shown) by the action of a vacuum. The cavity 7 protrudes from one side (for example, from the lower side) of the layer 6. The shape of the cavities 7 is chosen so that they have a transverse edge forming an acute angle with the longitudinal axis of the first layer 6. In step B, the cavities 7 are filled with additive 8. In step C, on the first layer 6, from the side opposite to that of the cavity 7 (for example, the upper side), the second layer 9 is placed. In step D, the layers 6, 9 are hermetically connected to each other, for example, by heat sealing. Around each of the cavities 7, an airtight joint zone 10 is formed, forming pockets 2 in the tape 1.

Other methods for manufacturing the tape 1 may be used. For example, the cavities may have a regular shape, for example, with transverse edges perpendicular to the longitudinal axis of the first layer. In this case, on the part of the zone of the tight connection between the pockets there may be transverse edges forming an acute angle with the longitudinal axis of the tape.

In a similar way, other versions of tapes with a low-strength sealing area can be manufactured.

For example, zones without a tight joint can be left between the pockets so that the zone with a tight joint at the transverse edge of each pocket has a width less than that of the longitudinal edges of each pocket. When pressure is applied to the pocket, the tape layers diverge in this narrower sealed area, and the pocket breaks.

Alternatively, the tight joint area at the longitudinal edge of each pocket can be made narrow enough so that the layers of the tape diverge in this zone.

In any case, the tight joint zone can be made less durable by including one or more unsealed portions therein. For example, a tight joint area may include a narrow unsealed portion (“line”) extending through it in a direction perpendicular to the edge of the pocket. The line is small enough so that the additive can pass through it, but simplifies the divergence of the layers of the tape. The sealing strength can also be controlled, for example, by changing the temperature of the welding device.

The tape 1 can be wound on a bobbin and then pulled from a bobbin into a stream of filter material bundle passing through a filter making machine to be embedded in a long filter rod. Next, the cutter of the machine cuts an extended filter rod into segments to form individual filter rods, each of which contains one or more pockets 2. This filter manufacturing process is generally similar to the process described in WO 2010/003899, in which a tube containing an elongated capsule of WO 2010/003899, replaced by tape 1. WO 2010/003899 is incorporated into this description by reference.

Thus, the methods described above facilitate the installation of the pocket 2 and its area with reduced strength in a predetermined position in the filter 3.

In some examples, part of the tape 1 along its longitudinal edge can be bent in the opposite direction and hermetically connected to the tape 1. Due to this, the tape 1 will decrease longitudinal elongation in tension and increase the longitudinal tensile strength. This, in turn, can simplify operations with the tape 1 during the production process, for example, when the tape 1 is wound on a reel and then wound from it.

In FIG. 6a shows another example of a section 11a of a tape 11 located inside a cellulose acetate insert of a filter 13 of a cigarette 14. Section 11a includes a first pocket 12a containing a fluid and a second pocket 12b containing a fluid. The pair of pockets 12a, 12b has the same longitudinal arrangement along the belt 11. As shown in FIG. 6b, the pockets 12a, 12b are arranged so that when a finger presses on the outside of the filter, both pockets 12a, 12b simultaneously tear together and simultaneously release both additives in the form of a fluid. Areas with reduced strength (not shown) of each pocket can direct the smoke modifier towards the cigarette stick and / or towards the mouthpiece end of the cigarette, and the direction can be determined by the type of additive, as described above.

The tape 11 can be manufactured and included in the filter 13 using methods similar to those described above.

In FIG. 7 shows another example of an additive release component 15. The additive release component 15 is a substantially elongated tube, preferably having a substantially circular or elliptical cross section.

The additive release component 15 may be in the form of a tube with rounded ends. From the rounded ends, a flange 16 may protrude, which may contain an excess of material to form the outer shell.

The additive component 15 has a reduced strength line 17. The line of reduced strength runs longitudinally, preferably substantially along the entire length of the additive component 15. The additive component 15 can only be torn along the line of reduced strength, or can be first torn along the line of reduced strength and immediately after that tear over essentially the entire area of the component 15 that gives the additive. The line of reduced strength can be formed by the junction between the two parts of the component 15, emitting additive.

The additive release component 15 can be manufactured using the blow-fill-seal process and the bag-fill-seal process.

In FIG. 8 shows another example of an additive release component 20. The additive release component 20 includes a housing 21 and additive 22. Additive 22 may include fluid, powder, or any other suitable additive material. The housing 21 is formed of an elastic material, preferably a polymeric material, for example polyvinyl alcohol (PVA). The housing 21 includes a tubular portion 21a, at one end of which there is a first end section 21b, and at the other end there is a second end section 21c. Sections 21a, 21b and 21c together form a container for additive 22.

The first end section 21b includes an end wall that covers one end of the tubular section 21a. This end wall is preferably rounded. The tubular section 21a may have a generally cylindrical shape closer to the first end section 21b, and the first end section 21b may include an end wall essentially in the form of a hemisphere, as shown in the drawing.

The walls of the tubular section 21a are deformed at the second end section 21c to form a blockage. Preferably, the wall sections corresponding to the two opposite halves of the tubular section 21a are flattened and brought into contact, the contact area being a substantially flat rectangle. The two wall sections can be connected to each other in any suitable manner, as will be shown below.

The additive release component 20 can be prepared as follows. First, an unsealed body is formed, i.e., body 21 without a second end section 21b, using any suitable process. Then, the unsealed case is filled with additive 22. For this, it may be necessary to hold the unsealed case vertically with the open end facing up. Then, the unsealed body is sealed by deformation and joining to each other of the wall sections of the tubular section 21a, with the formation of the second end section 21c. Wall sections can be connected to each other by heat sealing, ultrasonic welding, water-activated adhesive, or other suitable methods.

During use, the additive release component 20 is adapted to hold the additive 22 until it is released by the smoker. When pressure is applied to the component 20, for example, by a smoker, squeezing the filter on the outside in which this component is located, the component 20 breaks in the second end section 21c. In particular, the tight connection between the wall sections is made with the possibility of partial or complete rupture. Then, additive 22 is squeezed out of component 20 through a torn second end section 21c. Component 20 can be installed along the longitudinal axis of the filter and can have areas of reduced strength at either end so that additive 22 is released either toward the tobacco end or towards the mouthpiece end of the filter.

The additive release components 16, 20 can be connected by an extended element, for example, as described in WO 2010/003899, or they can be attached to the tape with an adhesive. A filter may then be manufactured using a method similar to that described above. Alternatively, the additive release components 16, 20 may be included directly in the filter.

Numerous other modifications, changes, and embodiments are possible.

For example, the additive containing element may be in a suitable shape.

In addition, although the introduction of the additive-containing elements into filter sticks has been described above, in other examples, the additive-containing element (s) may be located elsewhere in or on the smoking article, for example on the outer surface of the smoking article or inside a cigarette sticks. In some examples, the 1.11 tape can be made as a tear-off strip or as a filter wrapper or rim paper for use in the manufacture of smoking articles.

In addition, although the additive-containing elements have been described above, in the form of pockets containing the additive, in some examples the additive-containing elements may, alternatively, or in addition, contain, for example, aromatic beads or beads, or other solid objects having one or more components of the additive.

Further, although the pockets containing the additive discussed above release the additive under pressure, other release mechanisms can be imagined. For example, some elements containing the additive may release the additive by dissolving when moisture appears. In this case, when smoke is sucked out of the corresponding smoking article, moisture in the composition of the smoke may cause the release of the additive.

The terms “additive release component” and “additive containing element” are used interchangeably herein.

The components releasing the additive may be capsules having an outer shell containing the additive in the form of a fluid (liquid or powder) in the inner cavity. The outer shell of each additive release component can be easily broken by applying pressure to release the additive.

The filter may comprise a counter surface to which the additive release component can be pressed to facilitate release of the additive. In particular, the components emitting the additive can be placed on the side surface of the filter. The filter material adjacent to the radial direction can create a counter surface to which the additive release component can be pressed. Preferably, the filter material may be sufficiently solid (for example, contains an increased amount of plasticizer) to form a counter surface and may have a hardness of more than 90% according to the Filtrona scale. The components emitting the additive can be placed inside the filter material, or can be placed in a cavity adjacent to the filter material. The cavity may be formed by an elongated inner core of the filter material, which is surrounded by one or two annular outer sections of the filter material. A cover layer is attached to one or both of the outer sections of the filter material to form the outer part of the filter, spaced apart from the inner core to form a cavity. Preferably, the hardness of the inner core is greater than that of the annular outer sections, due, for example, to a higher plasticizer content.

Alternatively, each additive release component may release the additive contained therein in several discrete doses, preferably when activated several times with several separate pressure influences. An additive release component of this type may comprise an elastically or plastically deformable outer shell, preferably configured to release the additive through a slit formed in a predetermined region. In another embodiment, additive release components of this type may comprise an open-cell porous absorbent substrate (e.g., open-cell foam) containing the additive. The substrate may be at least partially resiliently deformable. The substrate is surrounded by an outer shell that provides retention of the additive, which can be brittle, elastically deformable, plastically deformable, or is a thin coating. The substrate may form discrete components that release the additive, or may be in the form of a ring in the first filter section. Alternatively, an additive release component of this type may include a porous matrix containing the additive in discrete cavities having a closed-cell structure (e.g., closed-cell foam) that may be subjected to plastic deformation to release the additive.

Additive release components may be individually attached to the filter or substrate. Alternatively, the components releasing the additive may be joined by tape and may be joined by laminated strips of sheet material. Alternatively, strips of sheet material may form the components releasing the additive, so that the components releasing the additive do not have a separate outer casing, and the strips of sheet material contain the additive.

The additive release components may be manually exposed to release the additive, or the additive from at least one of the additive release components may be released by the movable segment as it moves along the outer surface of the smoking article. The movement is the sliding or rotation of a ring or C-clamp located on the outer surface of the filter. The filter is a counter surface to which the components releasing the additive are pressed against the moving segment. The components emitting the additive are arranged in one or more gutters running in a circle, longitudinally or in a spiral. Alternatively, the movable segment comprises a cover layer forming two adjacent surfaces between which the additive release components are located, such that when the adjacent surfaces of the cover layer are mutually displaced, the additive is released from at least one of the additive release components.

The components releasing the additive preferably have a spherical shape. Alternatively, the components releasing the additive may have an oblong shape, with a longitudinal axis running parallel to the longitudinal axis of the filter. The elongated additive release component preferably has a round or elliptical cross section and contains more additive than the additive release component with the same diameter. The elongated component releasing the additive preferably has a transverse dimension of less than 3.5 mm or less than 3 mm, or from 2 to 3 mm. Alternatively, or additionally, the radial cross-sectional area of the elongated component releasing the additive may be less than 50% of the radial cross-sectional area of the smoking article and, if desired, less than 40% or less than 30%.

The components releasing the additive are preferably individually located in the smoking article. Alternatively, several additive release components are surrounded by an external wall or have external encapsulation. External encapsulation may contain pores or may be configured to break or deform so as to release the additive upon compression. External encapsulation itself is enclosed within additional encapsulation. The additive may be contained within several discrete cavities within an open pore substrate, or a closed pore substrate. The open-cell substrate and, if desired, the closed-cell substrate have external encapsulation. One or more additive release components may be attached to the outside of the additive release component having a substantially larger size. Alternatively, several additive release components having the same or different sizes may be bonded together. Any of these embodiments may be considered as several components integrated into a single structure.

Variants of the invention are made in such a way as to comply with applicable legal standards, for example, regulatory requirements related, in a particular example, to flavorings, additives, emissions, constituent substances and (or) other. For example, the invention can be made so that a smoking article that implements the invention , corresponded to the current standards before the release of the additive, after the release of the first additive and remained so after the release of one or more additional additives.
