Description

The The invention relates to a tobacco pouch with a novel closure mechanism, the safe reclosure of the tobacco pouch also at prolonged Use guaranteed.

tobacco pouch (also called tobacco pouches) for e.g. Pipe tobaccos and fine cut tobaccos have long been on the market. These essentially consist of a rectangular material web, partially (e.g., one-third of their larger extent) folded over is and on the outside edges welded in the folding area is to have a recording room for the To form tobacco. The supernumerary Area of the rectangular material web serves as a closure flap, those around the stuffed with tobacco Bag can be put around.

The long closure tab is beneficial because it's the diffusion path for the Gas exchange between tobacco and environment makes correspondingly long and thereby helps To maintain moisture and aroma of the tobacco as possible. For this Reason consist tobacco bags of the type described here as a rule made of printed plastic films or transparent plastic films, in which a printed material can be inserted. The plastic films are as thin as possible to avoid waste, but have to be firm enough to withstand the mechanical stresses during the normal handling enough To oppose resistance.

• a) direkt oberhalb der Fülllinie des Tabaks durch eine Versiegelung, die beim ersten Öffnen des Tabakbeutels zerstört wird, und
• b) durch ein Verschlusselement am Ende der Verschlusslasche.

Tobacco pouches of the type described are often closed in two places:

• a) directly above the filling line of the tobacco by a seal which is destroyed upon first opening of the tobacco pouch, and
• b) by a closure element at the end of the closure flap.

Out the prior art, a plurality of closure elements are known which it allow the flap wrapped around the tobacco pouch reliably hold in this position even after repeated use and thereby close the tobacco pouch.

At the common you will find the simple adhesive seal on the market. It deals an adhesive strip at the front end of the closure flap, which is simply pressed onto the closed tobacco pouch and thereby adheres to this. The disadvantage here is that these Adhesive tape due to contamination, z. B. by tobacco particles, after lose their grip for a short time.

The DE 8 713 894 U therefore suggests the use of multiple superposed adhesive strips. Dirty adhesive strips can be removed and a new, clean adhesive strip is used.

The DE 295 11 339 U proposes to provide on the tobacco pouch parts that can be separated and then placed as bands around the tobacco pouch to close this after use.

The DE 299 05 925 U is a further development of the aforementioned tobacco pouch. There are also magnetic strips that are incorporated into the tobacco pouch, used to ensure safe reclosure.

The EP 1 017 593 B1 proposes a closure having a bar and a mating counter bar, which are designed so that the bar can be easily pressed into the counter bar, there hooked and so closes the receiving space for the tobacco.

Velcro closures as a solution beat the DE 295 13 893 U and the EP 1 215 973 B1 in front. Like the tape but also the Velcro is prone to rapid contamination.

Finally, out of the DE 8 209 299 U a tobacco case known, which serves to receive a tobacco pouch and cigarette paper and is closed by a push button.

task The present invention is to provide a simple and stable To propose a closure mechanism for closing a tobacco pouch, Easy to handle and insensitive to contamination.

These Task is solved by a tobacco pouch according to claim 1.

Advantageous embodiments are defined by the features of the subclaims.

Of the tobacco pouch according to the invention consists of a rectangular material web, with a first area, in which the material web is folded over and fixedly connected at the outer edges, e.g. welded, glued, sewn or pressed. The connecting line, e.g. a seam closes it resulting receiving space for the tobacco on the sides as possible close to a gas exchange between receiving space and environment to prevent. A second area of the material web, an extension one of the open ends of the receiving space, can be used to close the Recording room over the folded and laterally closed first area be placed so that in the collapsed state the second area the first area covered over a large area.

Around the first area which forms a closure flap for the tobacco pouch in the hold closed state, the tobacco pouch has a closure on, which consists of at least two parts. A first closure part is on an outside of the recording room for the tobacco is formed on the material web. He can jump out of the Material of the material web to be formed and so a part of the material web form, but it is preferred if the first closure part on glued the material web, welded or other suitable Way anchored firmly on the material web. The first closure part stands out from the material web to the outside. He has one Base plate, which serves to connect to the material web and of a closure element perpendicular to the web and of the recording room paves the way. This closure element has directly on the base plate on a first diameter, which is Enlarged with increasing distance to the base plate. This enlargement of the Diameter can be done continuously, directly on the base plate Start or start at some distance from the base plate. It is also possible the closure element is connected to the base plate with one foot is and on the base plate repellent end, in a sense on the head, experiencing a sudden enlargement. It would be possible too a crown-shaped Formation of the projecting from the base plate closure element. in principle all forms of a closure element should be recorded here, the with a corresponding counterpart a secure and frequent resealing allow the tobacco pouch.

The The invention is not limited to a single first closure part. It can on the outside the tobacco pouch, a plurality of first closure parts be applied in the opening direction are arranged in a row behind one another or with each other. in principle is any number and arrangement of first closure parts allowed, which ensure a secure closure of the tobacco pouch.

One second closure part in the form of a stiff, band or a Lasche, the counterpart to forms the first closure part, is at the second region of the Receptacle bag attached to the locking tab. Is preferred it is attached to the side of the second area, e.g. glued, welded or sewed, which points outwards in the closed state of the tobacco pouch, particularly preferably in the middle of the second section, based on its width, that is the dimension that is perpendicular to the welded outsides. It should not be excluded that the second closure part on the inside of the Closing tab of the tobacco pouch is attached. The second closure part could be designed so that it at least in the area in which it is fastened on the closing tab of the tobacco pouch, of two there are separate layers and one layer on the outside, the other is attached to the inside of the closure flap.

The The invention is not limited to a single second closure part limited, but it can, matching the first closure parts, even two or more second Be provided closure parts. Finally, it should not be excluded be that the closure flap itself the second closure part forms.

Of the second closure part has in its front portion, that is the section that points away from the locking tab, at least a breakthrough for receiving the first closure part. The Shape of the breakthrough is chosen that they are over with light pressure the head of the first closure part can be pressed and a secure Ensures closure of the tobacco pouch.

Around the user an easy opening and closing to enable the tobacco pouch In a preferred version, the strip is the second closure part forms from a flat, relatively strong but elastic thin plastic material shaped. This strip or tab projects over the closure tab of the Tobacco bag, in particular by a length of more than 40% of their Length. At its foremost end, that is, before the shooting breakthrough for the first closure part, the second closure part is slightly bent or cranked. In the closed state of the tobacco pouch, this bend or cranking away from the tobacco pouch, thereby gripping the second closure member is facilitated by the user.

The Invention will be described below with reference to a preferred embodiment explained in more detail. Show it:

1 a schematic representation of an unfolded tobacco pouch,

2 a section through side view of a closed tobacco pouch,

3 Side view and top view of a second closure part of the bag according to the invention,

4 Side view and top view of a first closure part of the bag according to the invention, and

5 first and second closure part engaged with each other.

The 1 shows a tobacco bag in the unfolded state. It is on the right side a first area 1 formed by the fact that two layers of the tobacco bag forming film were superimposed and welded at the edges. The welds 4 form together with the Umlegkante 5 a recording room 3 for receiving the tobacco 6 (represented by the dashed lines). On the left is a second area 2 to see that over the area 1 can be placed and thereby the opening 7 of the recording room 3 closes.

The 2 shows the tobacco pouch in the closed state, again by dashed lines in the receiving space 3 located tobacco 6 is hinted at. It is good to realize that the second area 2 around the first area 1 is wound and thereby the opening 7 of the recording room 3 is closed.

The 3 shows a second closure part 8th , The second closure part 8th has a breakthrough 9 on, which is provided to the head of a first closure part 13 take. The shape of the breakthrough 9 is chosen so that the second closure part 8th on the first closure part 13 can be pressed. These are projections 14 in the breakthrough 9 so formed, for example, by a toward the center of the breakthrough 9 decreasing material thickness that they do when placed on a suitably shaped counterpart 12 be pressed, yield elastically and spring back to their original position. How to get in 3 can recognize is the second closure part 8th in a front section 10 who is behind the breakthrough 9 begins and until the end of the second closure part 8th is enough, slightly bent. The bend points away from the tobacco pouch when the closure is closed and serves to secure the second closure part 8th can be easily grasped by the user.

The 4 shows a first closure part 13 placed directly on the outside of the tobacco pouch, which when folding the tab 2 is not covered by this, is attached. This attachment may be an adhesive, welding or other suitable method of attachment. The first closure part 13 has a base plate 11 , which rests on the tobacco pouch, and a molded nose 12 pointing towards the tobacco pouch surface from the base plate 11 protrudes. baseplate 11 and nose 12 are preferably a single molded part, but it could also be two parts that are glued together, welded or positively connected. It is also conceivable, though less preferred, that the nose 12 is formed directly from the material of the tobacco pouch and forms a unit with the tobacco pouch.

The front end of the nose 12 has an outward widening, which is a retaining shoulder 15 forms. Will the second closure part 8th with his breakthrough 9 over the nose of the first closure part 13 pressed, so the protrusions 14 be pressed over the shoulder due to their elasticity and by their elastic restoring force behind the retaining shoulder 15 snag. Thus, a safe and reusable reliable closure of the tobacco pouch 1 guaranteed.

In 5 is the first closure part 13 on the second closure part 8th pressed together, and the two together form the closure of the tobacco pouch, not shown 1 , Good to see is the function of the section 10 the second closure part 8th , as well as the interaction of the shoulder 15 of the first closure part 13 with the projections 14 the second closure part.
