Definitions

  • the invention relates to a tobacco bag having a front wall and a rear wall, which are formed from a bag film and connected at the side edges by longitudinal sealing seams to a receiving pocket, wherein the rear wall extends beyond an upper edge of the receiving pocket, on which also terminates the front wall, and a flap which can be folded over onto the front wall, wherein a removal opening is provided at a distance from the upper edge, wherein a reclosing device with a first and a second closure strip is arranged in the region of the removal opening within the receiving pocket, and wherein the closure strips reversibly connectable to one another are not in the seams are integrated at the side edges.
  • the reclosing device may in particular be a so-called zipper closure, which has releasably latchable profiles with one another.
  • knob-like, self-locking closure strips are known.
  • a lock can be achieved via closure strip, which are provided with Velcro hooks.
  • the invention relates to a configuration in which a removal opening is provided on the front wall. Before a first-time use, the removal opening can already be formed by a punched out or an incision. However, the invention also includes embodiments in which the removal opening is prepared before the first use only by a weakening line or the like and still needs to be torn open by a user. Even such a merely prepared removal opening is generally referred to as a removal opening in the context of the invention.
  • tobacco bags In addition to ready-to-smoke cigarettes, in practice tobacco for rolling cigarettes or for stuffing pipes is offered loosely in tobacco bags, these tobacco bags being easy to handle, regardless of the degree of filling.
  • Tobacco pouches as disposable packaging usually have a filling weight of between 10 g and 100 g, in particular between 30 g and 50 g.
  • such tobacco pouches have a front wall and a rear wall, wherein the front wall and the rear wall form a pocket by lateral connecting seams and wherein the rear wall extends beyond the front wall. After removing a single portion of tobacco, the bag can be rolled up, wherein the tab formed by the protruding part of the rear wall is folded over the front wall.
  • a tobacco bag with the features described above is from the EP 1 812 303 B1 known, wherein a removal opening is provided independently of a filling opening.
  • a transverse sealing seam wherein one of the closure strips of the reclosing device is fastened both to the front wall and to the rear wall.
  • the upper sealing strip With the transverse sealing seam closing the bag, the upper sealing strip is also sealed between the front wall and the rear wall. Since the closure strips do not extend over the entire width, there are areas along this transverse sealing seam in which the front wall, the upper closure strip and the rear wall are superposed in three layers and the front wall lies directly on the rear wall laterally.
  • closure strip or a connection lug of the closure strip has a comparatively large material thickness, a step is created at the end of this closure strip. In order to close the bag safely despite this stage, a large heat and force entry in the sealing necessary. In particular, the visual appearance of the tobacco pouch is significantly affected.
  • the invention has for its object to provide a tobacco bag, which is easy to close after filling or has a reliable tightness and a high-quality appearance after closing.
  • both closure strips are attached only to the front wall, wherein the first closure strip is secured with a terminal lug so between the removal opening and the upper edge by a transverse seal that between a upper end of the terminal lug and the upper edge of a top front wall portion remains with a height of between 2 mm to 15 mm, wherein the first closure strip from the transverse sealing seam extends downwards and has a connection to the connecting lug connecting portion.
  • the uppermost front wall section is left above the upper end of the connecting lug in order to arrange there a transverse sealing seam which directly connects the front wall to the rear wall without the integration of the first closure strip.
  • the front wall and the rear wall are superimposed in two layers, so that no transitions are present and excessive deformations of material accumulation can be avoided.
  • the generation of the transverse seal for connecting the front wall and the rear wall is thus possible in a simple manner, with a reliable closure before a first-time opening of the tobacco pouch is guaranteed.
  • the transverse sealing seam connecting the front wall and the rear wall is hardly noticeable to a user and does not affect the appearance of the tobacco pouch.
  • the tobacco pouch according to claim 1 comprises both a not yet filled, open and a filled and sealed tobacco pouch.
  • the present invention is based on the finding that although the removal opening is arranged as far as possible above, the uppermost front wall section should nevertheless be kept free for a direct connection of the front wall to the rear wall.
  • the height of the uppermost front wall section that is to say the distance from the upper end of the connection lug to the upper edge of the receiving pocket, where the front wall also ends, is particularly preferably between 3 mm and 10 mm, for example approximately 4 mm, against this background. Said distance is sufficient to form a transverse sealing seam for closing the receiving pocket, which directly connects the front wall and the rear wall without the involvement of the upper closing strip.
  • the removal opening can still be arranged relatively high up on the front wall.
  • both closure strips of the reclosure are attached only to the front wall.
  • the closure strips are connected to one another only via connection sections which can be detached from one another and are not directly sealed with one another. An additional sealing process or material deformations due to the fusion of the closure strip can thus be avoided.
  • the two closure strips of the reclosure are also not involved in the longitudinal sealing seams on the side edges, whereby material accumulations, excessive material deformation and possible leaks can also be avoided there. It is within the scope of the invention but advantageous if the closure strips are brought as close as possible to the longitudinal sealing seams to provide the largest possible removal opening and to limit the air exchange along the gap between the ends of the closure strip and the respective associated longitudinal sealing seams. Thus, it is preferred if the closure strips terminate at a distance of 1 mm to 5 mm in front of the longitudinal sealing seams.
  • an incision or a cut-out in the front wall can be provided directly during production.
  • only one weakening line is produced in the front wall, which is intended to form the removal opening.
  • Such a weakening line in the form of a perforation, weakening of the material and / or embrittlement of the material ensures a better closure than an incision or a cutout before it is opened for the first time.
  • the line of weakness is severed by a user.
  • the weakening line includes a front wall section which can be torn off to form the removal opening.
  • a tearable front wall portion is preferably completely removed upon first opening of the tobacco pouch, thereby providing a large dispensing opening which is also easy to handle.
  • the second closure strip is usually fastened below the removal opening by at least one transverse sealing seam.
  • the second closure strip can also have a connection lug and extend downwards from the attachment to the front wall with the connection lug, wherein a connection section then adjoins the connection lug.
  • the front wall and the rear wall are preferably folded from a foil sheet, wherein the fold edge forms the lower edge of the receiving pocket.
  • the bag film is heat-sealable on one side, which also forms the inner surface of the receiving pocket. Heat-sealability is not required on the opposite outer side, wherein melting the outer layer in the production of the longitudinal sealing seams and the transverse sealing seams would lead to considerable optical impairments.
  • a multilayer film having a heat sealable layer on the first surface and a non-heat sealable layer on the second surface is preferably used.
  • the layer on the second surface forming the outer surface of the tobacco pouch should have a higher melting point so that melting during heat sealing can be avoided.
  • the heat-sealable layer may consist of a polyolefin, in particular PE or PP.
  • the layer arranged on the opposite surface can be formed, for example, from a polyester, in particular polyethylene terephthalate (PET) or else a biaxially oriented polypropylene (BO-PP).
  • laminated films can be used with an internal imprint, the imprint then optimally against damage and abrasion is protected. As a result, a high-quality appearance is permanently ensured during use.
  • the foldable tab covers after folding the front wall at least partially. Whether the end of the tab on the front wall or in a complete covering of the front wall only folded down again comes to rest on the back wall depends on the length of the tab, the filling of the tobacco pouch and the arrangement of the fold from where the tab in the upper area the receiving pocket is folded. In the context of the invention, it is also possible that the receiving pocket is wrapped with the tab so far that the end of the tab even on the tab itself, so comes to rest on the rear wall above the upper edge of the receiving pocket. The tab can be folded, for example, above the upper edge of the receiving pocket. Furthermore, it is also possible to fold over part of the front wall including the reclosing device. In the context of such an embodiment, it is preferred if the end of the tab also already covers the entire front wall in a completely filled receiving pocket and folded around the bottom of the tobacco pouch on the rear wall to lie.
  • an adhesive strip may be provided on the outside of the tab.
  • a pressure-sensitive adhesive or a double-sided adhesive strip or adhesive dot can also be arranged on the inside of the flap.
  • the invention also provides a process for producing a tobacco pouch according to claim 9.
  • cut foil sheets can in principle be supplied individually, provided with a reclosing device, folded and sealed.
  • the bag film is fed as a continuous web, wherein only after the folding of the bag film and after the production of the longitudinal sealing seams the endless web is cut into individual tobacco pouch.
  • Such a method has advantages, especially in mass production, whereby the continuous web can initially be handled easily.
  • the closure strips running transversely in the finished bag are preferably fed to the reclosing device parallel to the advancing direction of the endless web.
  • a portion of the continuous webs is then folded over to form the front wall and the rear wall.
  • Such folding can be achieved in particular during transport of the film web by folding knife or the like.
  • the continuous web runs in a direction parallel to the transverse direction of the finished bag.
  • the longitudinal sealing seams between the individual bags are then also generated perpendicular to the direction of advance, wherein corresponding longitudinal sealing seams are still generated on the continuous, previously folded continuous webs.
  • individual bags along the formed longitudinal sealing seams cut off.
  • the produced seal seam thus corresponds to twice the width of a single longitudinal seam after cutting.
  • transverse seal and longitudinal seal used in the definition refer not to the direction of movement of the bag film, but to the structure of the finished tobacco bag.
  • longitudinal sealing seams can also be produced transversely to the advancing direction and transverse sealing seams parallel to the advancing direction of the continuous web or a foil sheet provided for forming the tobacco pouch.
  • the tab 6 depending on their length and the degree of filling of the receiving pocket 4 as in the Fig. 1 shown on the front wall 1 or on the rear wall 2 can come to rest with its end. Therefore, if starting from the embodiment according to the Fig. 1 a longer tab 6 is provided, it also surrounds the bottom of the receiving pocket. Furthermore, the bend line, on which the flap 6 is folded forward, may be provided at different positions. According to the Fig. 1 the flap 6 is folded forward immediately above the upper edge.
  • the tobacco bag has, according to the general construction, a front wall 1 and a rear wall 2, which are formed from a bag film and are connected at the side edges by longitudinal sealing seams 3, whereby a receiving pocket 4 is formed.
  • the rear wall 2 extends beyond an upper edge 5 of the receiving pocket 4, on which the front wall 1 ends, beyond, wherein this protruding portion of the front wall 1 forms a hinged flap 6.
  • the tab 6 is in the unfolded state in a fully filled bag on an outer side of the front wall 1 and can be fixed there, for example with an adhesive strip 7.
  • the receiving pocket 4 can be rolled up, in which case the adhesive strip 7 can also come to rest on the outside of the front wall 1.
  • the details of the tobacco pouch according to the invention are from the Fig. 2 . 3a and 3b seen.
  • a removal opening 8 is provided, for which purpose in the front wall 1, a line of weakness 9 is introduced in the form of a perforation.
  • the weakening line 9 is self-contained and includes a tear-off front wall section 10.
  • the tear-off front wall portion 10 When first opening the filled, closed tobacco pouch ( Fig. 3b ), the tear-off front wall portion 10 is completely removed, whereby a large and thus easy to handle removal opening 8 is exposed.
  • a reclosing device 11 with a first closure strip 12a and a second closure strip 12b is arranged in the region of the removal opening 8 within the receiving pocket 4.
  • both closure strips 12a and 12b each have a connection lug 13a, 13b and a connection section 14a, 14b, which connect at the end to the respectively associated connection lugs 13a, 13b.
  • the reversibly connectable closure strips 12a, 12b are not incorporated into the lateral longitudinal sealing seams 3 and preferably end at a distance a of 1 mm to 5 mm in front of the longitudinal sealing seams 3.
  • the first closure strip 12a is secured with its terminal lug 13a between the discharge opening 8 and the upper edge 5 by a transverse sealing seam 15 that between the upper end of the terminal lug 13a and the upper edge 5, a top front wall portion 16 with a height h between 2 mm to 15 mm, preferably between 3 mm and 10 mm, in the embodiment remains about 4 mm.
  • the closure strip 12a extends with its connection lug 13a downwards.
  • Fig. 3a shows the not yet closed tobacco pouch is in the Fig. 3b the filled and represented by a further transverse sealing seam 15 'closed tobacco pouch.
  • this further transverse sealing seam 15 ' is arranged above the first sealing strip 12a, this further transverse sealing seam 15' connecting the uppermost front wall section 16 directly to the rear wall 2. Over the entire length of this transverse sealing seam 15 ', this results in a two-layer arrangement of front wall 1 and rear wall 2, so that no steps, material collections or the like must be taken into account.
  • an embodiment is specified in which the two closure strips 14a, 14b are directly connected to one another only via the connecting sections 12a, 12b.
  • a direct sealing of the two closure strips 12a, 12b is not provided.
  • the two closure strips 12a, 12b are integrated neither in the lateral longitudinal sealing seams 3 nor in the transverse seam 15 'provided for closure, whereby a simple, direct contact of front wall 1 and rear wall 2 is always provided in these sealing seams which are decisive for the closure of the tobacco pouch ,
  • the height h is selected such that the transverse sealing seams 15, 15 'can be arranged next to one another without the first closure strip 12a being connected to the rear wall 2 during the closure of the receiving pocket 4.
  • the reclosure with the two closure strips is sealed onto a film section along transverse sealing seams 15, 15 ", which form the front wall 1.
  • the attachment of the reclosing device 11 can be effected in a particularly simple manner with a flat foil sheet or a flat material web, before the folding of this foil sheet or the film web, the front wall 1 and the rear wall 2 are formed
  • the longitudinal sealing seams 3 is an unfilled tobacco pouch according to Fig. 3a before, which is subsequently filled and closed with the sealing seam 15 'at the upper edge 5.
  • Fig. 3a and 3b show a preferred embodiment in which both closure strips 12a, 12b terminal lugs 13a, 13b have, extending from the respective associated transverse seam 15, 15 "down.
  • the transverse sealing seam 15 is further offset downwards for fastening the second closure strip 12b, with the associated connection lug 13b then extending upward Fig. 3a and 3b
