Definitions

• the invention relates to a tamping device for the self-production of cigarettes by transferring a strand-shaped tobacco insert from a tubular Feiri motherboard partial quantity packaging made of non-consumable material into a cigarette paper sleeve, consisting of a tubular sleeve with a coupling end for pushing on the free end area of the tubular Fei chnitt and partial packaging this tubular sleeve axially displaceable ejection piston.
• a tamping device for better transfer of the strand-shaped tobacco inlays, a tamping device has been proposed in accordance with EU 0 140 129, which consists of a tubular sleeve with a coupling end for attaching or sliding on the free end region of the tubular fine-cut partial packaging and an ejection piston which is axially displaceable with respect to this tubular sleeve.
• the one provided here tubular sleeve is designed as a sliding sleeve and has a conically shaped coupling end for receiving the free-standing end of the tubular fine-cut portion packaging.
• this tamping device has the disadvantage that once the free-standing. End of this tubular fine-cut partial packaging is not fit, and sometimes also with a damaged cigarette paper sleeve edge, is placed on the outlet opening of the tubular sleeve, and on the other hand, that this process e.g. is carried out on construction sites with sometimes dirty fingers of the operator, which is uncomfortable for the actual smoker. Ultimately, the user of the device is seduced, the sliding sleeve, usually held in the left hand, with the already attached
• the present invention has for its object to propose a tamping device according to the preamble main claim, with which the transfer of a strand-shaped tobacco insert from a tubular fine-cut partial packaging in a cigarette paper tube can be carried out more simply, uniformly and hygienically.
• partial-quantity packaging can also be used in which the tobacco portion is somewhat looser than in a conventional cigarette, or in which at least in the end area of the partial packaging that comes into engagement with the ejection piston - which is also referred to below as the “free end area” * - the tobacco is loosely stuffed.
• This facilitates the transfer of the tobacco portion into the cigarette paper tube, and in the latter case also the insertion of the import piston at the start of the tamping process.
• a tamping device which is characterized in that a) the coupling end of the tubular sleeve is designed as a cylindrical pipe socket, the outer diameter of which is slightly smaller than the inner diameter of the tubular fine-cut partial packaging, and after 0.5 to 1.0 cm behind the outlet opening changes into an annular bead, the outer diameter of which is slightly larger than the outer diameter of the tubular fine-cut portion packaging, b) at the coupling end with an axial distance of about 1 to 5 mm to the opening of the cylindrical pipe socket to at least over the annular bead a tubular sleeve made of rubber-elastic material is provided, the inside diameter of which is slightly larger than the outside diameter of the tubular fine-cut portion packaging and is dimensioned such that there is an annular gap for receiving the free end area of the tubular shaped fine-cut partial packaging, c) the tubular sleeve has an axially extending guide slot at a distance from its two ends, and that d
• Characteristic a ensures that the free end of the tubular fine-cut partial packaging can be placed precisely on the tubular sleeve because of the annular bead serving as a stop.
• Characteristic b) ensures that the consumer does not hold the freely protruding remainder of the tubular fine-cut portion packaging with his possibly dirty fingers, but indirectly and evenly via the rubber sleeve, in order to then compress the discharge piston, possibly with compression of the looser portion of tobacco, also in the attachment area of the ejection piston, to actuate and thereby obtain a uniformly stuffed cigarette.
• the opening of the cylindrical pipe socket is preferably slightly beveled, which serves for a better introduction of the open end of the tubular fine-cut partial packaging. It is also advantageous if, following the annular bead serving as a stop, an annular groove is provided on the side facing away from the opening of the pipe socket, which passes into the tubular sleeve and which is still covered by the tubular sleeve. This serves to better fix the sleeve and results in a better transition to the tubular sleeve, which is somewhat larger in diameter.
• At least one axially extending groove is provided in the annular bead, in which at least one inwardly directed cam provided on the inside of the rubber sleeve engages in press adhesion.
• the width of the channel is preferably approximately 1.45 mm and that of the cam approximately 1.5 mm.
• the tubular sleeve has two opposite slot-shaped recesses in its front area, which in turn contributes to better elasticity when pressing the free ends of the tubular packaging or holding them on the cylindrical pipe socket of the coupling end.
• these slit-shaped recesses serve as a viewing window in the stop area of the annular bead, with which the user can control the precise insertion of the free area of the partial packaging.
• a conically tapering cup-shaped depression is provided at the head end of the tamping device, the bottom surface of which has a diameter which is somewhat smaller than that Outside diameter of the partial packaging is.
• FIG. 1 shows a perspective view of a tamping device
• FIG. 2 shows a longitudinal section through the tamping device according to FIG. 1
• FIG. 3 shows a side view of the tubular sleeve without a sleeve.
• the tamping device consists of an approximately 15 cm long tubular sleeve 2, one end of which is closed and provided with a fastening clamp 26, while the other end serves as the coupling end 4.
• the latter has a cylindrical pipe socket 6 for receiving the free end of the fine-cut partial packaging and is slightly chamfered in the opening area for easier insertion and can have a slight annular thickening.
• the outside diameter of the cylindrical pipe socket 6 is slightly smaller than the inside diameter of the tubular fine-cut partial packaging.
• annular bead 8 serving as a stop, which limits the insertion depth of the free end of the partial packaging and together with the annular thickening at the opening for a safe opening Ensure that the partial packaging is on the coupling end.
• annular bead 8 Further in the direction of the closed end of the tubular sleeve, an approximately 5 mm wide annular groove 10 is provided behind the annular bead 8, which passes into the main part of the tubular sleeve 2.
• the coupling end 4 is surrounded by an approximately 15 mm long annular sleeve 12 made of rubber-elastic material, which is seated on the annular bead 8 and extends over the area of the annular groove 10 to the beginning of the actual tubular sleeve 2.
• the groove 10 prevents the rubber sleeve from shifting in the axial direction.
• the opening area of the cylindrical pipe socket 6 remains about 1 to 2 mm free in the axial direction in order to allow the free area of the partial packaging to be put on. The latter is then pushed over the slight annular thickening of the opening of the cylindrical pipe socket 6 into the annular gap 14 under the annular sleeve 12, the inside diameter of which is slightly larger than the outside diameter of the partial packaging.
• the annular sleeve 12 On the side facing the opening of the cylindrical pipe socket 6, the annular sleeve 12 also has two axially running, approximately 7 mm long, slot-shaped recesses 16, which lie opposite one another in a 180 ° arrangement and increase the elasticity of the sleeve and, when pressed together, the one in the annular gap 14 hold the inserted free area of the partial packaging and also serve the user as a viewing window for checking the insertion depth of the free end of the partial packaging up to the stop on the annular bead 8.
• At least one approximately 1.45 wide axially extending channel 9 is provided in the annular bead 8, or on the upper side thereof, into which an approximately 1.5 mm wide cam 13 provided on the inside of the rubber sleeve 12 is pressed in intervenes, which serves for better fixation of the Gumn_rimanschette 12.
• an ejection piston 20 is arranged to be axially movable, which has a web-shaped cam 22 at the rear end, which engages through a longitudinally extending guide slot 18 in the tubular sleeve 2 and is designed as an annular actuating handle 24, preferably all around the tubular sleeve 2 is.
• the piston can be fluted for better guidance in the tubular sleeve, for which purpose the latter has inwardly directed guide lugs.
• a conically tapering cup-shaped depression 28 is provided, the bottom surface of which has a diameter that is slightly smaller than the outside diameter of the partial packaging.
• the tubular fine-cut partial packaging is inserted into a customary cigarette paper tube, preferably into one with a filter mouthpiece, whereby a "sharpening" of one end of this package in the cup-shaped recess 28 at the end of the tamping device facilitates this process other, so-called free end of the partial packaging on the cylindrical pipe socket 6 up to the stop on the annular bead 8 in the annular gap 14 and under the sleeve 12th pushed. It is also possible to first place the free end of the partial packaging on the cylindrical pipe socket 6 and then to push the cigarette paper sleeve over the partial packaging, which is preferably “sharpened” at this end.
• the free end of the partial packaging is then pressed onto the cylindrical pipe socket 6
• the cuff 12 is held by thumb and index finger and the ejection piston is pushed in the direction of the partial packaging, through which the tobacco portion in the partial packaging gets into the cigarette paper tube and the user pushes or separates the evenly filling cigarette paper tube from the partial packaging then off and the emptied partial packaging almost detaches itself from the coupling end and can be discarded.
• the tamping device that is the tubular sleeve forming a unit and the ejection piston located therein, can be made of plastic, approximately the size of a pencil, and can be assembled economically with the rubber sleeve.
