The embodiments of bag packages 10 serve to receive a portion of tobacco 11 , The bag is made of thin packaging material, in particular of a thermally sealable film. A blank is forming a bottom edge 12 folded, leaving a front wall 13 and a back wall 14 opposite each other or the actual bag for receiving the tobacco portion 11 form. In the area of lateral edges are front wall 13 and back wall 14 permanently connected, through (upright) side seams 15 . 16 , The back wall 14 is provided with an extension or continuation to form a flap 17 with the bag closed against the front wall 13 folded and connected to this detachable, z. B. with an adhesive label 18 ,

An upper area of the bag or front wall 13 and back wall 14 is as a bag opening 19 educated. This extends between the side seams 15 . 16 , About the bag opening 19 becomes the tobacco portion 11 filled and taken at consumption. In the closed position are upper edge strips of front wall 13 and back wall 14 to each other or are connected to each other by separable closure means.

The closure means or closure members may be formed in various ways. In the embodiment of the 1 are in the area of the bag opening 19 arranged two cooperating closure strips, namely magnetic strip 20 . 21 , These extend in the region of a filling material-free opening strip 22 from front wall 13 and back wall 14 between the side seams 15 . 16 , In the closed position are the corresponding polarized magnetic stripes 20 . 21 together. Above the closure means or magnetic strip 20 . 21 is located in the area of the front wall 13 a grip tab 23 used to open or disconnect the magnetic strip 20 . 21 can be detected. 1 and 6 show the open position with separated magnetic strip 20 . 21 , 7 shows a closed position after first opening the bag pack 10 ,

A special feature is the arrangement of a further closure means in the region of the bag opening 19 , ie in the area of the opening strip 22 , It is one for putting the bag pack into use 10 detachable connection of front wall 13 and back wall 14 , The present embodiment is a sealed seam 24 in the "Peel Seal" version. The Peel Seal material is a waxy plastic that acts as a very thin sealing strip 25 one-sided or two-sided on insides of front wall 13 and back wall 14 is applied. The connection is made by heat and pressure. The additional closure means, so the seal 24 On the one hand, it has the task of creating a (originally) completely sealed pouch when the multiply acting closure means does not seal completely or leaves open openings due to the dimension at the ends. Furthermore, the seal has 24 a security effect against unauthorized opening of the bag.

In the embodiment according to 1 and 2 such as 5 to 7 this (second) closure member is located above the multiple-acting (first) closure means, namely above the magnetic strip 20 . 21 , When opening the bag pack 10 Therefore, first the seal seam 24 open. After that, the magnetic stripes 20 . 21 separated from each other ( 6 ). When resealing only the magnetic strips 20 . 21 forced shut. In the area of the sealed seam 24 remain the seal strips 25 without connection.

The magnetic closure member may according to 13 also be designed so that a magnetic strip 21 with a counterstrip 26 made of ferromagnetic material. The magnetic stripes 20 . 21 are in the region of edge strips opposite polarity, such that the oppositely poled areas in the closed position to each other ( 15 ).

The bag pack 10 according to 3 whose construction and handling are also in 8th to 10 are shown, works with a molding strip 27 as a reusable closure member. This wider strip 30 that is only on one side of the bag opening 19 , especially on the back wall 14 is arranged, consists of a plastically deformable material, in particular of metal (aluminum alloy). Due to this material property of the molding strip 27 with the layers of the opening strip 22 be folded into a closed position ( 10 ), which is kept stable. The form strip 30 is by gluing, but preferably by thermal sealing with the back wall 14 connected, wherein the molding strip 27 optionally may have a thermally activatable coating on one or both sides. The form strip 27 extends here across the entire width of the bag, including in the side seams 15 . 16 ,

In the production engineering predetermined closed position ( 8th ) is the molding strip 27 without deformation in the area of the folded over opening strip 22 , This lies with turned out flap 17 on the bag. After first opening ( 9 ), the closing position by folding over the opening strip 22 approximately in the center of the molding strip 27 causes so that this receives a U-shaped folding position ( 10 ).

Also in this embodiment of the bag package 10 a second closure member is provided, namely a connection strip 28 which is in the area of the opening strip 22 is arranged on the inside, in particular opposite to the molding strip 27 ( 9 ). The connection strip 28 consists of a material which due to heat and / or pressure with the molding strip 27 can be connected and is ineffective after first opening. In particular, there is therefore the connection strip 28 from Peel Seal material.

The bag pack 10 according to 4 is designed in a special way. The multiple-acting closure member consists of two elastic, but relatively stiff support strips 29 . 30 , in particular of plastic or metal (steel). The two support strips 29 . 30 are in the area of the bag opening 19 on the inside of front wall 13 and back wall 14 between the side seams 15 . 16 appropriate. The ends can be supported on each other ( 12 ). The operation of this closure member looks like that in the transverse direction (arrow 31 ) Pressure on the ends of the support strips 29 . 30 is exercised so that they bulge under elastic deformation to the outside. It is characterized by a corresponding bag opening 19 released. By relieving the ends, the support strips return 29 . 30 due to the elasticity in the starting position back, in which they are sealingly against each other.

Also, this embodiment is provided with a second closure means, namely a sealed seam 24 with peel seal effect above the support strips 29 . 30 Mistake.

A special feature is the production of the bags or the attachment of the closure strip. According to 16 becomes a continuous (film) web 32 processed or processed for the bags. The train 32 is transported with the inside facing up. In a first step, in the area of the local bag machine, but alternatively already in a plant for the production of the web 32 can be used, two continuous strips of sealable or adhesive material (Peel Seal) are applied to form the two sealing strips 25 , The sealing strips 25 are applied with thin film thickness, so that the web 32 with the sealing strips 25 as Bobine wrapped available can stand.

The intended for multiple use closure means is in the field of a bag machine on the optionally prepared in the above sense path 32 applied. According to 16 and 17 become strip-shaped pieces 33 . 34 as closure strips spaced apart on the web 32 applied and connected to this. The pieces 33 . 34 are arranged at a transverse distance from each other, so that after folding the web 32 forming a continuous covering and creating the continuous bottom edge 12 the pieces assigned to each other 33 . 34 as a closure against each other ( 17 ).

After formation of the partial coverage of the train 32 become the transverse side seams 15 . 16 appropriate. After or at the same time the bag packs 10 from the train 32 separated. In the open bag is now the tobacco portion 11 introduced ( 18 . 19 ). Thereafter, the closure is made, at least through the organs or pieces 33 . 34 , preferably by additionally connecting the sealing strips 25 the sealed seam 24 , The bag pack 10 is ready to use.

Another special feature are units or aggregates of a device. The device according to 21 is the schematic representation according to 16 assigned. From a continuous strip 35 in particular of a bobbin or roll 36 is withdrawn, are in the range of a cutting unit, the pieces 33 . 34 separated. The stripe 35 For this purpose, the circumference of a cutting roller 37 fed. This has (two) knives 38 on that during the rotation of the cutting roller 37 with a stationary counter knife 39 work together and each one piece 33 . 34 from the strip 35 split off. Due to the rotational speed of the cutting roller 37 becomes the severed piece 33 . 34 accelerated, so that when placed on the below the cutting roller 37 ongoing train 32 the desired distance between successive pieces 33 . 34 is created.

The ones with the (closing) pieces 33 . 34 provided railway 32 becomes after transport about along a quarter circle on the circumference of the cutting roller 37 deflected by this and on the periphery of a second roller, namely a heating roller 40 transferred. The two rollers 37 and 40 are arranged with their lateral surfaces immediately adjacent to each other. A wedge-shaped deflector 41 in the region of the smallest distances between the lateral surfaces of each other causes the transfer of web 32 and with the pieces 33 . 34 on the circumference of the heating roller 40 ,

In the area of the heating roller 40 becomes the continuous unit of track and (closure) pieces 33 . 34 to the heating roller 40 pressed by a Andrückorgan which extends over a larger peripheral region of the heating roller 40 extends. It is a pressing belt 42 with one at the periphery of the heating roller 40 clinging trum 43 , The surface of the heating roller 40 is heated, by two along a portion of the circumference extending heating strips 44 . 45 ,

In this device, therefore, heat and / or pressure on the web 32 in the field of pieces 33 . 34 transferred due to appropriate arrangement of the heating strips 44 . 45 , The device is therefore suitable for all closure means by heat and / or pressure on the web 32 be fixed. As far as magnetic stripes are concerned 20 . 21 These are after leaving the roller 40 in the area of a horizontal conveying section of the railway 32 by an activating organ 46 magnetized, namely by a magnetizing coil. The so equipped railway 32 can now be further processed in the manner described.

How out 25 can be seen, are for mounting two parallel closure elements or pieces 33 . 34 two cutting rollers 37 at a suitable distance from each other above the track 32 arranged. The cutting rollers 37 white suction holes 47 on to fix the strip 35 and the pieces 33 . 34 on the circumference of the cutting roller 37 ,

26 shows a cross-sectional detail of the heating roller 40 , These for both pieces 33 . 34 common heating roller 40 is formed with a corresponding axial dimension. baseboards 44 . 45 are arranged at an axial distance from each other according to the distances of the pieces 33 . 34 , Each heating bar is an (electric) heating element 48 assigned.

22 shows a device for the attachment of self-adhesive (closure) pieces 33 . 34 at the train 32 , The stripe 35 can on the provided with a self-adhesive coating side with a cover strip 49 Be provided before the transfer of the strip 35 on the circumference of the cutting roller 37 deducted and carried away. Instead of the cover strip 49 can not glued side of the strip 35 with an adhesion preventing coating, e.g. B. a barrier paint, be provided.

The self-adhesive pieces 33 . 34 be through the cutting roller 37 in the manner described on the web 32 hung up. Following the cutting roller 37 Activation can be done with magnetic stripes 20 . 21 by means of activation organ 46 ,

Another alternative emerges 23 , Here are closing organs, namely strips or pieces 33 . 34 processed, which are provided with a thermally activated coating, for. B. with hotmelt. The in the area of the cutting roller 37 outward coating is by a stationary heat source 50 activated. Immediately thereafter, the piece in question 33 . 34 to the train 32 created.

Another special device is in 24 shown. The closure member to be attached or the closure strip (s) extend over the full width of the bag. The closure means can therefore be considered as a continuous band 56 deducted from a bobbin and the web 32 be supplied. Both, namely railway 32 and band 56 be over a deflection roller 57 to the periphery of a connecting roller, namely heating roller 40 guided. This is provided with a circulating (electric) heating element, namely a heating strip 58 , This extends in the area of the band 56 , so that by transfer of heat and pressure the band 56 - optionally with coating - to the web 32 is sealed. To provide sufficient contact pressure for web 32 and band 56 at the periphery of the heating roller 40 to ensure, here is a Andrückband 42 provided, whose Trum 43 over a wide range of the circumference of the heating roller 40 extends. A lower deflecting roller 59 leads the now connected unit out of orbit 32 and band 56 back to a horizontal plane. This device is particularly suitable when using a molding strip 27 as a closure agent. At the train thus formed 32 the continuous band 56 is cut through ( 17 ).

For closing the tobacco-filled bag ( 19 / 20 ) heat and / or pressure on the or the closure organs are applied. If as the second closure means a sealed seam 24 is provided, this is in the field of the device according to 27 activated or closed. The finished, filled bags are in position according to 20 in a sealing unit 51 promoted, namely by means of conveyor belt 52 , During a stoppage phase of the bag pack 10 Heat and pressure are at least in the region of a closure member, in particular in the region of the sealed seam 24 transferred, through a seal 53 which from the top of the bag pack 10 can be lowered to transfer heat and pressure. Opposite to the strip-shaped sealing piece 53 there is an edition 54 as counter-pressure element below an upper run of the conveyor belt 52 , The edition 54 consists at least partially of elastic material. After leaving the sealing unit 51 are the bag packs 10 finished or closed. In an embodiment of a bag package 10 according to 3 such as 8th to 10 becomes the connection between the molding strip 27 and the connection strip 28 of thermally activatable material also by a device analog 27 produced.
