Description

The The invention relates to a closure for a film, in particular a transparent film containing a packing container, in particular a Cigarette packs, hits. Specially concerned the invention for closing container wraps around Cigarette packs made of transparent film material, for example Cellophane or polypropylene.

The use of films as packaging material for cigarette packs or packaging containers ("bars") is generally known, for example, describes the DE 33 35 310 A1 the connection of parts of the impact of cigarette packets by heat sealing of transparent cases, and from the DE 1 586 717 the production of a pack of packets of cigarette packs with transparent film and sealing techniques is known.

If, as in the latter prior art document, continuous Sealing seams to be used on the container packaging is the container despite possibly existing tear strips difficult to open, and especially packs in the frontal area are difficult to remove. If the container film only with several Sealing points, it will depend on the number of Sealing points either mechanically very unstable and opens even with normal handling inadvertently, or it is again very difficult to open and packs are bad removable.

It the object of the present invention is a package container foil closure to be provided with regard to the package opening and Packing is optimized. In particular, a stable container be provided from the packs if necessary without further notice can be removed.

These Object is achieved by a closure dissolved for a film according to claim 1. The subclaims define preferred embodiments the invention.

According to the present invention is the film at individual seal points stapled, with seal points of different holding strength the film are arranged. In other words, the inventive Aim by providing sealers with different levels of stability reached. This measure makes it possible for the Make packaging stapling particularly suitable in suitable places, while remaining relatively loose elsewhere. With There are many possibilities for this choice Options, on the one hand the stability on the other hand the easy opening possibility over to make the extension of the package intelligent.

So are in accordance with an embodiment of the invention at the areas relevant for container shape conservation the film firmer seal points, especially with more or larger Sealing points or sealing surfaces provided. At the for the container shape preservation less relevant areas it is possible to provide weaker seal points, especially those with fewer or smaller sealing points or sealing surfaces.

For example can at the frontal areas of a container side of a elongated container, in particular a cigarette container with five times two packs, seal marks with larger ones Holding strength can be arranged, while the other hand Possibility exists at the middle areas of such Container side to arrange sealing sites with lower holding strength.

The Siegelstellen designed according to the invention can on the folded or overlapping edge of the film They are specifically designed as separate seal points on one Container side are arranged, between which unsealed edge sections remain. These unsealed spaces allow then a good engagement in or under the film envelope, so that the container can be opened easily.

It there is a possibility of the seal points as a number of sealing points or as sealing surfaces with elongated ones Form propagation, according to a design variant the sealing points arranged at intervals on the edge of the film are and perpendicular in their elongated spread extend to these.

• – eine unterschiedliche Breite und/oder Länge der Siegelstellen,
• – bei unterschiedlichen Temperaturen erfolgte Versiegelung
• – bei unterschiedlichem Druck erfolgte Versiegelung, oder durch eine Kombination solcher Maßnahmen.

The different holding strength of the various sealing sites can be produced by various measures, namely by:

• A different width and / or length of the sealing sites,
• - Sealing carried out at different temperatures
• - Sealing occurred at different pressures, or by a combination of such measures.

According to a further aspect, the invention relates to a sealing device for closing a film, in particular a transparent film, which strikes a packaging container, in particular a cigarette pack, the device having sealing elements, which are adapted for producing different, in particular different strength, sealing sites. The sealing device is particularly suitable and configured to produce a closure as described herein in various embodiments.

• – mit unterschiedlicher Größe bzw. unterschiedlichen Abmessungen,
• – mit unterschiedlicher Form,
• – mit unterschiedlichen Stoffverbindungseigenschaften bzw. unterschiedlicher Stoffverbindungsfestigkeit, insbesondere unterschiedlicher Verpressung bzw. Verschmelzung, oder Siegelstellen mit einer Kombination solcher Ausbildungen.

The sealing elements can be designed so that they can produce seal points of different training, in particular seal points

• - with different sizes or different dimensions,
• - with different shape,
• - With different compound properties or different material connection strength, in particular different compression or fusion, or sealing sites with a combination of such training.

According to one Execution are the sealing elements heating strips or Heating baking, which the film by heat application, and in particular also by pressure, seal at the seal sites.

• – mit Hilfe einer Steuerung bzw. Regelung zum Versiegeln auf eine unterschiedliche Temperatur gebracht werden,
• – in einer unterschiedlichen Höhe in der Richtung senkrecht zur Folie (3) angeordnet oder ausgebildet sind, wodurch ein unterschiedlicher Wärmeeintrag in die Siegelstellen entsteht und/oder unterschiedlich starke Kräfte bei der Verpressung der Folie an der Siegelstelle wirken;
• – eine unterschiedliche Form, insbesondere Breite und/oder Länge, oder Flächenabdeckung haben, oder eine Kombination solcher Merkmale aufweisen.

Furthermore, it is still possible that the sealing elements, which produce the different holding-tight seal points, especially the heating jaws / heating strips:

• Be brought to a different temperature by means of a control or regulation for sealing,
• At a different height in the direction perpendicular to the film ( 3 ) are arranged or formed, whereby a different heat input into the sealing sites arises and / or different strong forces in the compression of the film act at the sealing point;
• - Have a different shape, in particular width and / or length, or area coverage, or have a combination of such features.

The The invention will be further explained with reference to an embodiment and explained in more detail with the aid of the accompanying drawings. It may have all the features described herein individually and in any reasonable sense Combine. In the drawings show:

1 the arrangement of the packages in a container;

2 the arrangement of the seal points on a container wrapping film in the same view as the figure; and

3 an end view of the container.

In the embodiment shown according to the invention is a container 2 from cigarette packs 1 wrapped with a transparent film, the cigarette packs in 1 seen from its narrow front and in two levels of five packets of cigarettes 1 are superimposed. This arrangement corresponds to the usual container form, which is known as "rod".

Like from the 2 shows, is on this visible, narrow longitudinal side of the container and the rollover 11 (Overlap) of the container foil 3 arranged, which is used to seal the film. In other words, the rollover 11 overlaps the film 3 , which lies underneath and essentially covers the entire area. The dashed line indicates that the rollover extends up to two-thirds of this container side.

The container also has a tear strip, the tab with the reference numeral 5 has been provided.

According to the invention are between the container film 3 and the rollover 11 formed several separate seal points. The seal sites are here designed as elongated rectangles, which are perpendicular to the edge of the rollover 11 extend away to the upper edge. Already from the 2 becomes clear that narrower seal points 9 and wider seal points 7 and this representation is also schematic for the weaker seal sites 9 and the firmer seal sites 7 , Due to the firmer sealing points, which are arranged in the front side area, a high stability of the entire package, while the weaker sealing points 9 facilitate the opening of the container, but provide sufficient stabilization in the middle region. cuts 13 In the areas towards the front sides ensure that the container impact can be removed over almost the entire length of the packs and so a good access is possible.

The arrangement and relatively lower strength of the seal sites 9 makes it relatively easy for a user, between two seal sites 9 under the envelope 11 to grasp and to open the container by scribing. Although the individual, separate seal points 7 . 9 no continuous seam termination, so that penetration of moisture or escape of moisture into the container through the container envelope or film could not be completely prevented. However, in the vast majority of cases, the cigarette packs are 1 even completely sealed by means of a film and protected against moisture loss or moisture penetration. The present invention has therefore aufge in this context, the usual continuous seams with the knowledge ben, that they are actually no longer necessary, so that other sealing types according to the invention can greatly simplify the handling.

In 3 again are two flashovers 4 shown, which are present on the end face of the container. In a package of the present invention, these envelopes can also be used 4 be provided with separate seal points. This also means, in principle, that the arrangement of sealing sites with different holding strength does of course not have to be limited to one container surface when the present invention is implemented. On the other hand, the envelopes 4 be sealed on the front side in a conventional manner, if the present invention necessary adjustments in terms of stability and pack removability on the longitudinal surface (see 2 ) suffice.

• – indem die schmalen Heizleisten/Heizbacken unterschiedliche Temperaturen erhalten,
• – indem die schmalen Heizleisten/Heizbacken unterschiedliche Höhe (senkrecht zur Folienoberfläche) haben und dadurch
• a) unterschiedlich starken Hitzeeintrag auf die Siegelstellen bewirken und/oder
• b) unterschiedlich starke Kräfte bei der Verpressung der beiden Folien wirken lassen, und
• – indem die Breite der Heizleisten/Heizbacken unterschiedlich gestaltet wird.

In the manufacture of a closure of the container wrapping according to the present invention, a plurality of individual narrow heating strips can be used on the package packaging machine, which are arranged at intervals to one another. Different strength sealing can then be accomplished in a variety of ways, such as:

• - by the narrow heating strips / heating jaws get different temperatures,
• - By the narrow heating strips / heating jaws have different height (perpendicular to the film surface) and thereby
• a) cause different levels of heat on the sealing sites and / or
• b) different forces acting on the compression of the two films, and
• - By the width of the heating strips / baking jaws is designed differently.

These Means allow, individually or in any combination, the free and requirements of the design of the seal points in terms of their arrangement and holding strength.
