  • Patent number: 5749378
    Abstract: A tobacco product for self-preparing a cigarette, especially a filter-tipped cigarette, includes a tobacco portion (14) matched with the tobacco filling of a finished cigarette and having an air-permeable outer surface so that it cannot be smoked per se. The outer surface of the tobacco portion is completely smokeable or consumable by smoking, is dimensionally stable and its cross-section and length match the tobacco receiving space (13) of a cigarette paper tube (11) so that the outer surface of the tobacco portion engages the cigarette paper of a cigarette paper tube with the tobacco portion shape retained. An outer bar wrap (15) over the tobacco portion, open at either end, is made of non-smokeable material and transferred from the bar wrap (15) into the paper tube (11). The bar wrap (15) is formed of poorly or non-combustible material such as aluminum-laminate, synthetic plastic film, tin foil, aluminum foil or the like.

  • Patent number: 5615692
    Abstract: A method and apparatus for filling or packing cigarette-paper tubes is described wherein the apparatus comprises at least one tobacco-transfer means, in the form of a plunger or the like is mounted on a housing so as to be axially displaceable to transfer at least one tobacco strand out of a strand casing disposed within the housing into an associated cigarette-paper tube. At least one nozzle is mounted on the housing to which the open end of the cigarette-paper tube is connected in such a way that during transfer the tobacco passes through the nozzle into the associated tube. Within the housing is defined a receptacle in which at least one tobacco-filled strand casing is disposed and within which the strand casing is held and externally supported so that it cannot be displaced during transfer of the tobacco strand into the cigarette-paper tube.

  • Patent number: 5526825
    Abstract: Smoking tobacco is provided for self-making finished cigarettes. A tobacco unit (47) includes a plurality of sub-quantity portions (48 or 50, respectively) which are held together by inner and/or outer fixing means (49) to form a stack of separable portions. Each quantity portion (48 or 50) contains substantially the tobacco quantity required for a finished cigarette. The outer surface of the tobacco unit (47) and/or the sub-quantity portions (48 or 50) are all permeable to air such that the tobacco unit or each portion is not drawable as such and hence cannot be smoked. The tobacco portions of unit (47) are each configured like a rod and interconnected by paste to form a rod belt (51), or are configured as a flat oval tobacco unit comprising the plurality of sub-quantity portions (48) as a continuous mass.

  • Patent number: 5450861
    Abstract: A manual filling device for cigarette tubes, comprising a tobacco compression chamber extending in longitudinal direction of said device and being defined by a housing (12) disposed in a bottom part (14). A pressing bar (16) is provided on a lid (18) which is hinged to the housing (12) and covers said housing (12). A spoon (20) and an ejector slide (22) is provided for ejecting a compressed tobacco bar from the tobacco compression chamber through an opening (24) formed in said housing (12) into a cigarette (filter) tube. A clamping member (59) clampingly retains the cigarette tube on a socket piece disposed at the exit from the tobacco compression chamber. A locking or snap-in unit (60) releasably connects said housing (12) and said lid (18), and includes a substantially hook-shaped detent (62) provided on an elastic web (78) joined to the free end (64) of the lid (18) opposite the hinged connection (34) between lid (18) and housing (12).

  • Patent number: 5197495
    Abstract: A "make-your-own" system for making a cigarette, especially a filter-tipped cigarette, includes a dimensionally stable tobacco portion (10) matched with the tobacco receiving volume (16) of the cigarette located within a cigarette paper wrapper. The paper wrapper is in the form of a cigarette tube (11) for closely enveloping the tobacco portion (10). The tobacco portion (10) is formed like a cigarillo including an outer wrapper (13) of tobacco or a tobacco blend which imparts to the smoker of the made tobacco portion and therefor to the cigarette approximately the taste and flavor of a factory-made cigarette or a conventional cigarillo clothed as a cigarette.

  • Patent number: 5072740
    Abstract: A device for filling prefabricated cirgarette tubes, especially filter-tipped cigarette tubes, comprising a tobacco pressing chamber (14) with a filling opening (13), in which tobacco introduced through the filling opening (13) is pressed to form a tobacco rod (10) by means of a pressing beam (17) movable transversely to the longitudinal direction of the tobacco pressing chamber (14), a socket for fitting the cigarette tube thereon, clamping means for retaining the cigarette tube on the socket, and an ejector (25) for ejecting the tobacco rod (10) from the pressing chamber (14) into the cigarette tube. In order to prevent tobacco fibres from projecting out of the filling opening of the tobacco pressing chamber, a separate lid (1) cooperates with the filling opening (13) of the tobacco pressing chamber (14), the closing movement of said lid being in advance of the movement of the pressing beam (17) is pressing direction.

  • Patent number: 4887617
    Abstract: A tobacco product for the personal preparation of a cigarette, in particular a filter cigarette, includes an inherently stale tobacco portion (10) corresponding to the tobacco filling of a finished cigarette. The surface of the tobacco portion is defined by a wrapping or sheath (13), which consists of completely smokeable material. The sheath is permeable to air and the tobacco portion can only be smoked after tight wrapping of the sheath 13 with cigarette paper. The diameter of the tobacco portion (10) is smaller--preferably only slightly--than the inner diameter of the wrapping of cigarette paper or the like such as a preformed cigarette paper sleeve (11) for easy insertion of the tobacco portion (10) into the sleeve. In order to ensure that the tobacco portion (10) bears tightly within the cigarette paper, the tobacco portion (10) is responsive to heating to expand and tightly engages the cigarette paper and at least in the region of the glowing area (17).

  • Patent number: 4249546
    Abstract: An apparatus for filling empty cigarette blanks in which tobacco is placed in a tobacco magazine. When an operating lever is actuated, a pressure plate compresses the tobacco into a column. Upon further actuation of the lever, an elastic rack expels these columns so formed through a boss on which the cigarette blank is held by pincers. In order to adapt the apparatus to cigarette blanks of various lengths, in particular to cigarette blanks having single or dual filters, there is provided a movable slide which limits the amount of tobacco placed in the tobacco magazine to correspond to the amount required by a particular cigarette blank.
