Definitions
- the invention relates to a filter sleeve for smoking devices according to the preamble of claim 1.
- a filter in various designs are known from practice which are used in smoking devices and smoking products, such as pipes, cigars and cigar tips, as well as cigarettes and cigarette tips, or the like.
- a filter consists of a sleeve jacket and at the end of two end elements, for example in the form of end walls.
- ends elements for example in the form of end walls.
- perforations in the terminal end elements are characteristic, so that the known filters can be flowed through in the longitudinal direction.
- a filter is inserted into a smoking device or a smoking product before the user consumes it.
- DE1602963U discloses a filter insert for cigar or cigarette tips and pipes, which has stopper-shaped closure members of the sleeve, so that simplified insertion and secure fastening is made possible.
- the plugs are made of an absorbent material and are firmly connected to the sleeve.
- a filter cartridge for pipes, cigar and cigarette holders is known, the end walls of which are closed by capsules. At least one of the two capsules has a hollow shape in order to be able to increase the interior space for holding a filter material without influencing a fixed overall length of a filter cartridge.
- DE9017930U1 describes a generic filter for smoking devices, with a filter sleeve made of chlorine-free filter paper and end walls in the form of end plates form the filter. Holes in the end caps allow tobacco smoke to pass through.
- DE19527471A1 also teaches a generic filter for smoking devices.
- a filter material and a filter sleeve material are defined, which can additionally be a carrier of, for example, flavorings.
- the filter can be constructed in one part or in several parts, in which several filter parts are connected to one another by means of a plug-on element, so that a combination of divergent filter materials that are arranged one behind the other is made possible.
- EP1512335A1 discloses a filter which has a conically shaped jacket body and a conically shaped interior, so that an optimal adaptation to the generally widespread conical shape of smoking products takes place and the filter effect is thereby improved.
- the filter interior is filled with filter material in the factory before the filter interior is inaccessibly closed for a user by means of an end element.
- the known filters for smoking devices are united by the problem that the interior of the filter is not accessible to the user of a smoking device or a smoking product without destroying the filter. A user-specific filling of the filter interior with filter material is not possible. In addition, the known filters are not reusable without having to accept the filter effect.
- the object of the invention is to improve the known filters in such a way that a user is able to is set to individually adapt the filter effect from a health perspective as well as with regard to the personal taste experience.
- the invention is to be based on multiple uses.
- the invention proposes that the interior of a filter sleeve has an adjacent opening through which a user is able to fill the interior of the filter sleeve according to individual preferences before use.
- a user can specifically influence the qualitative filtering of specific groups of molecules or substances from the smoke to be inhaled by means of the type of filter material.
- the use of activated carbon has been established in practice.
- a quantitative control of the filter effect on the part of the user can advantageously be defined via the amount of the filter material.
- the size of the absorbed surface of the filter material is also important in this context. By selecting a grain size composition of the filter material accordingly, a user can additionally manipulate the filter performance.
- An additional individualization of the smoking experience can be achieved by adding aromatic and / or flavoring substances to the filter material.
- An addition to the filter material is advantageous if direct exposure of the aroma and / or flavor substances to high temperatures is to be avoided, so that an immediate addition to the smoky herb is excluded.
- the sleeve casing of the filter sleeve is essentially conical on the outside.
- An external thread arranged on the sleeve casing is exempt from a conical shape.
- an opening is advantageous, which adjoins the interior of the fil terhülse, arranged on the end face in the filter sleeve, the opposite end being delimited by an end wall.
- the opening can be closed with a device called a stuffing sleeve.
- the stuffing sleeve is optionally inserted into the interior of the filter sleeve to different degrees, so that the interior volume can be infinitely defined by the user.
- the variability of the interior volume enables the inclusion of different amounts of filter material depending on the personal preferences of a user of the object according to the invention.
- the filter material can be compressed by inserting the stuffing sleeve.
- a higher density increases the diffusion and flow resistance of the filter material, so that the flow velocity of the smoke through the filter material is reduced. As a result, an individual taste development can be influenced.
- a higher degree of compression of the filter material means that the actively absorbing surface is reduced and the filter effect is reduced.
- the end wall of the stuffing sleeve which can be inserted into the interior of the filter sleeve is advantageously designed in the shape of a truncated cone in order to make it easier for a user to use it when inserting the stuffing sleeve into the interior.
- the cross section of the stuffing sleeve and the cross section of the interior essentially correspond in order to be able to ensure adequate sealing of the interior of the filter sleeve and targeted smoke guidance within the filter and stuffing sleeve.
- the cross-sectional dimensions of the The stuffing sleeve should be slightly smaller so that the stuffing sleeve can be inserted into the filter sleeve.
- a further component referred to as a union sleeve, is used to receive the filter sleeve with its front end, including the stuffing sleeve, which has the opening.
- the sleeve casing of the filter sleeve has an external thread and the union sleeve has a complementary internal thread. Internal and external threads work together in such a way that the sleeve body of the union sleeve extends beyond the front end of the filter sleeve.
- a stop is also arranged in the coupling sleeve, which can be designed, for example, as an inner collar and partially reduces the inside diameter of the coupling sleeve.
- the stop limits the maximum receiving depth of the filter sleeve in the coupling sleeve as soon as the section of the stuffing sleeve protruding from the interior of the filter sleeve axially abuts the stop on the one hand and the filter sleeve on the other hand.
- an advantageous union sleeve makes it possible, on the one hand, to use a smoking device or a smoking product and, at the same time, to avoid the transmission of unwanted odorous substances or substance deposits on the hands of a user.
- the coupling sleeve thus functions as a clean solution of a coupling element between a smoking device or a smoking product and the user handling the smoking device or the smoking product.
- the compression material in the interior of the filter sleeve is brought about by the stuffing sleeve lying axially against the stop.
- the filter effect and the accompanying taste development on the part of a user of the object according to the invention is determined by the individually determined quantities of filter material and the depth of reception of the filter sleeve in the coupling sleeve. binding with a smoking device or a smoking product can be defined.
- the inside diameter of the stuffing sleeve essentially corresponds to the inside diameter reduced in the area of the stop of the union sleeve.
- the coupling sleeve advantageously has an insertion end in the area opposite the receiving area of the filter sleeve, beyond the stop, which serves to receive a mouthpiece.
- the construction of the insertion end takes into account the compatibility with insertion pieces of commercially available mouthpieces, such as those used for e-cigarettes or the like.
- the mouthpiece represents an essential component for the development of taste.
- the insertion end can be axially limited by the stop located inside the coupling sleeve.
- the stop on the insertion end can be conical. It is also particularly advantageous if the inside diameters of the stuffing sleeve, the union sleeve in the area of the stop and the mouthpiece essentially match in order to avoid turbulence which promotes deposition in favor of a largely laminar smoke flow.
- the inner surface of the sleeve has a circumferential groove into which a sealing lip for sealing the interior of the filter sleeve.
- holding means are also provided, for example in the form of a thread, as a bayonet connection or as a clip closure, which releasably attach the end wall opposite the stuffing sleeve and are designed in the same way as holding means on the portion of the stuffing sleeve protruding from the interior of the filter sleeve.
- the compatibility of the holding means is the starting point for a transport arrangement which simplifies the handling of the object according to the invention by the user when used repeatedly. To do this, all components are first separated from one another. It is particularly advantageous then to transfer the end wall of the filter sleeve opposite the stuffing sleeve into the receiving space of the union sleeve.
- the filter sleeve is then screwed into the receptacle of the union sleeve and the holding means of the stuffing sleeve are connected to the complementary holding means of the filter sleeve.
- the stuffing sleeve also advantageously has an undercut, for example in the form of a groove following the circumference of the stuffing sleeve.
- the object according to the invention is positively and / or non-positively connected to a carrying system.
- An advantageous embodiment of an undercut can be realized in the form of a transverse bore in the stuffing sleeve, through which a retaining band or a chain can be passed, which a user of the object according to the invention can carry around his neck, for example.
- the transport arrangement simplifies multiple use of the subject matter of the invention.
- it can act as an accessory for the user.
- a multiple use of the object according to the invention is also ensured in that the sleeve jacket, the end walls, the stuffing sleeve and the union sleeve are made of metal, plastic and / or ceramic.
- the procedure for producing a use arrangement of the object according to the invention is as follows: first, the end wall opposite the stuffing sleeve can be connected to the filter sleeve via the cooperating holding means, provided the end wall is in the disassembled state. Subsequently, according to the individual preferences of a user, the interior is filled with one or more filter materials and, if appropriate, with additives, for example in the form of aroma or flavoring substances, if necessary with the aid of a funnel, and the stuffing sleeve inserted into the opening of the filter sleeve.
- the filter sleeve is installed in a smoking device or in a smoke product, for example in a paper wrap, so that a smoke herb is located in front of a second end wall.
- the external thread of the filter sleeve is then screwed into the internal thread of the union sleeve and the filter sleeve is thereby inserted into the receiving area of the union sleeve until the section of the stuffing sleeve protruding from the opening of the filter sleeve axially abuts the stop of the union sleeve and the the degree of compaction preferred by the user of the filter material or of the filter material mixture has been reached.
- a user By actively manipulating the characteristics of filter material, additives and degree of compaction, a user is able to individually influence the smoking experience both from a health perspective and in terms of taste. Finally, a mouthpiece with the plug-in socket is inserted into the plug-in end of the coupling sleeve, which completes the arrangement of uses.
- a user initiates a suction effect on a mouthpiece
- smoke emanating from a burning smoky herb is conveyed into the interior through openings through a second end wall.
- the filter effect is achieved in the interior by the filter material located there or by the filter mixture.
- the filtered smoke which may contain additives, passes through openings in a first end wall and finally reaches a mouthpiece.
- the geometry of an interior shape of the room influences the flow behavior of the smoke, so that the cross sections in the interior of the components downstream of the filter sleeve are matched to one another and essentially correspond.
- Specific embodiments of mouthpieces can cause the smoke to be swirled in a targeted manner and, in conjunction with this, a defined taste development.
- the possibility of using a wide variety of mouthpieces also individualizes the specific flavor.
- the use arrangement of the object according to the invention can be dismantled, the components cleaned and, if necessary, fed to a transport arrangement.
- 1 is a filter sleeve in longitudinal cross section
- 2 a stuffing sleeve in longitudinal cross section
- Fig. 3 is a sleeve in longitudinal cross section
- FIG. 4 shows a perspective view of a filter sleeve with an inserted stuffing sleeve and overlapping union sleeve.
- a filter sleeve (1) is shown in longitudinal cross section.
- a sleeve jacket (2) delimits an interior (4) of the filter sleeve (1), which serves to hold a filter material (5) or a filter material mixture and, if appropriate, further additives.
- the cross section of the interior (4) defined by the sleeve jacket (2) advantageously follows a cylindrical basic shape. Smoke-related deposits on the sleeve casing (2) can be removed much more easily with a cylindrical shape, and deposits in corner areas that are difficult to remove can be avoided.
- the outer shape of the sleeve casing (2) is advantageously essentially conical.
- a conical outer shape of the sleeve casing (2) is advantageous in that it is more difficult for the filter sleeve (1) to slide out of a smoking device or from a smoking product.
- a maximum increase of a second, distal outer diameter of 1 mm is useful. With smaller increases in the outside diameter, the likelihood of sliding out increases, whereas larger increases in the outside diameter require a higher amount of material and processing in the course of product manufacture, as a result of which the economy is reduced.
- a conical outer shape of the sleeve shell (2) is dispensed with in the area of an external thread (9). 1 shows that the sleeve casing (2) has a proximal external thread (9).
- the external thread (9) enables a continuous coupling of the filter sleeve (1) to other components.
- Arranged on the inside of the external thread (9) is a circumferential groove (16) into which a sealing lip (17) for sealing the interior (4) can advantageously be inserted. Sealing the interior prevents an uncontrolled flow of smoke, which counteracts a laminar flow of smoke and can thus negatively affect the taste experience. In addition, the reproducibility of the taste experience for the user is made more difficult by the varying smoke routing.
- FIG. 1 shows a filter sleeve (1) which has an advantageous opening (7) on the end, which adjoins the interior (4) of the filter sleeve (1) and can be optionally closed.
- the interior (4) can be filled by a user with filter material (5) or with a filter material mixture and, if appropriate, with further additives according to the individual preferences, so that an individualized setting of the filter features is made possible.
- the distal end wall (3) of the filter sleeve (1) opposite the opening (7) is designed to be removable, in which holding means (18) are used in order to either fix or release the end wall (3) , As shown, the use of a thread as holding means (18) is particularly advantageous.
- FIG. 2 shows a stuffing sleeve (8) with an end wall (3), which advantageously represents the proximal end wall (3). Openings (6) are contained in the end wall (3), which enable a flowing smoke flow as the basis of a filter effect.
- the end wall (3) is shaped like a truncated cone, in order to simplify the handling of the stuffing sleeve (8) when it is inserted into a filter sleeve (1).
- FIG. 2 further features of a stuffing sleeve (8) can be seen in FIG. 2, which are important for transporting the components.
- a holding means (18) formed as a thread is advantageous, which is designed to have the same effect as the distal holding means (18) of a filter sleeve (1).
- the stuffing sleeve (8) has a transverse bore (19). The procedure for producing an advantageous transport arrangement is as follows:
- the filter sleeve (1) is inserted into the receiving space (20) of the union sleeve (10) by screwing the external thread (9) of the filter sleeve (1) into the internal thread (11) of the coupling sleeve (10).
- the stuffing sleeve (8) is connected to the filter sleeve (1) by inserting the holding means (18) of the stuffing sleeve (8) formed as a thread into the complementary distal holding means (18) of the filter sleeve (1) shaped as a thread. is screwed.
- a chain or the like is guided through the transverse bore (19) of the stuffing sleeve (8), by means of which the components can be worn by a user, for example, hanging around the neck.
- a mouthpiece (15) with the plug-in socket can be inserted into the plug-in end (14) of the union sleeve (10).
- the transport arrangement enables a user to guide the filter sleeve (1) in a simple manner, so that the motivation for repeated use is promoted.
- FIG. 3 an advantageous embodiment of a union sleeve (10) is shown.
- an inwardly projecting stop (12) which is advantageously designed as a collar and partially reduces the inside diameter of the union sleeve (10), a receiving area (20) from an insertion end (14) spatially separated.
- the insertion end (14) serves to receive a mouthpiece (15).
- the geometry of the plug-in end (14) is compatible with plug-in sockets of standard hand-held mouthpieces (15), as are already used in e-cigarettes or the like. A user is thereby in able to continue using known mouthpieces (15). This is important in that a mouthpiece (15) can significantly influence the taste development when smoking.
- an advantageous internal thread (11) is arranged, which serves to couple the union sleeve (10) with the Fil terhülse (1), whereby the mouthpiece ( 15) is coupled to the filter sleeve (1).
- the union sleeve (10) opens up the possibility for a user to hold a smoking device or a smoking product without smells or deposits being transferred to the skin.
- FIG. 4 shows a perspective view of a filter sleeve (1).
- the filter sleeve (1) has a distal end wall (3) into which openings (6) are inserted and which is advantageously connected to the filter sleeve (1) by means of a thread as a holding means (18).
- a filter material (5) which a user can feed to the interior (4) of the filter sleeve (1) via the opening (7) according to individual preferences.
- the opening (7) of the filter sleeve (1) is closed by the stuffing sleeve (8) inserted into the interior (4).
- a cylindrical outer shape of the stuffing sleeve (8) is advantageous, as a result of which a higher seal can be achieved to improve the smoke flow.
- the degree of compaction of the filter material (5) or the filter material mixture with any additional additives in the interior (4) can be influenced by the user by inserting the stuffing sleeve (8) into the interior (4) to different degrees and the filter material (5 ) or the like is compressed depending on the pressure.
- the degree of compaction defines essential features such as inter alia the retention time of the smoke in the interior (4) and / or the binding-relevant surface size of the filter material (5).
- the degree of compaction is therefore an elementary factor in order to individually define the smoking experience from a health perspective and from a pleasure-focused perspective.
- a high degree of compression of the filter material (5) or the like can, for example, extend the retention time of the smoke in the interior (4), as a result of which the filter effect is enhanced by the more intensive separation of substances that are hazardous to health from the smoke flow. Simultaneously, the binding of taste-influencing substances to the filter material (5) can be increased, so that these are no longer available to a user for individual taste expression.
- FIG. 4 also shows an advantageous embodiment of a union sleeve (10).
- the filter sleeve (1) is received with its front end having the opening (7) by the internal thread (11) of the union sleeve (10) with the external thread (9) of the filter sleeve (1 ) interacts.
- the section of the stuffing sleeve (8) protruding from the interior (4) lies axially against a stop (12) in the inside of the union sleeve (10), which can advantageously be designed as a collar.
- the filter material (5) or the like is compressed by the stop (12) acting as an abutment and the stuffing sleeve (8) being pushed into the interior (4) when the filter sleeve (1) is screwed into the union sleeve (10).
- the receiving space (20) of the union sleeve (10) is extended in such a way that the union sleeve (10) extends distally beyond the opening (7) of the filter sleeve (1) and beyond the stuffing sleeve (8).
- the extension serves to improve the handling of the land, in that a grip or folding section is provided by the union sleeve (10), which protects the user against unwanted odors and / or deposits accumulated on the doldrums.
- an advantageous insertion end (14) is arranged proximally in the coupling sleeve (10), into which the insertion socket of commercially available mouthpieces (15) can be inserted.
- a herb of smoke is located in front of the distal end (3) of the filter sleeve (1), for example held in a paper wrap in which the filter sleeve (1) is installed.
- smoke is emitted from the burning herb, through openings (6) through the distal end wall (3) of the filter sleeve (1) into the interior (4).
- the smoke is filtered before it in turn passes through openings (6) through the proximal end wall (3) of the stuffing sleeve (8) and a smoke flow into the mouthpiece (15) takes place.
- the cross sections of the inner shapes of the stuffing sleeve (8), in the region of the flush stop (12) and of the mouthpiece (15) are essentially congruent. As a result, laminar smoke flow is supported. Special inserts for mouthpieces (15) can then cause a defined swirling in order to produce a targeted taste development for the user.
