Description

Technical area

The The invention relates to a packaging with a food, in particular Coffee in it, and a machine for making such Packaging.

On In the field of food packaging, on the one hand, it is common required to pack the food hermetically sealed to its freshness and, for example, in the case of coffee, its aroma to ensure even when open. Further should open the packaging to the consumer easily be. Finally, the producer of the food has one Interested in packaging with information such. B. one Brand, contents, user information, competitions, etc. to provide.

State of the art

From For example, the Applicants are under the brand name "coronation" coffee packaging known, which are largely cuboid and usually be offered standing on a narrow side. This packaging consists of an inner, made of foil, largely cuboid Inner bag and a so-called external winder, usually made of coated paper.

From the EP 1 608 567 B1 For example, there is known a flexible, vacuum-packaged bag having a reclosable opening by means of a label.

Presentation of the invention

Of the Invention is based on the object, a package with a Inner and outer packaging in terms of conservation the freshness of the packaged product over the life of the product To improve packaging. Furthermore, a machine for production be provided such a package.

The Solution to this problem is on the one hand by the in the claim 1 described packaging.

As a result, has these on the inner packaging and / or on an inner side the outer packaging at least one means, in particular an adhesive strip for resealing the packaging. The provision of a means, in particular an adhesive strip for Resealing, especially the inner packaging has the advantage that reclosing at the usually made of foil produced inner packaging particularly safe can be. For those for foil bags, in particular if they are to be sealed under vacuum, usually used films can be advantageously adhesives or find adhesives that are safe to reseal enable. In addition, the means for Reclosure in the initial state in an advantageous manner be "hidden" under the outer packaging. In other words, the appearance of the packaging must be by providing a means for resealing not necessarily change. Rather, the outer packaging can be unchanged stay. Only if the consumer the outer packaging opens to open the package altogether is he will find the means to reclosure and can do this after opening the inner packaging in use advantageously.

In In this context, there is an added value of Adhesive tape to reclose in that this with further information, such as B. a manual for opening the inner packaging and the use of the adhesive strip for reclosing, for additional advertising, competitions or the like can be used. At first try it over In addition, it has been found that such an adhesive strip to the Inner packaging film used for the production of inner packaging is, even with the extremely short cycle times, namely within of about 0.2 seconds, the packaging machines in use today prevail, let install. This applies in the same way for the alternative embodiment, in which the Reclosing means, in particular an adhesive strip, attached to the inside of the outer packaging. Also Here is the advantage that the outside of the outer packaging can remain unchanged, and that the consumer the described means, in particular an adhesive strip, then finds, if he opens at least part of the outer packaging removed the packaging altogether. For the last described embodiment is a lightweight and non-destructive release of the adhesive strip from the Inside of the outer packaging to allow preferred that the outer packaging on the inside at least partially a material, such as silicone, has, of An adhesive strip can be easily detached. According to the preferred embodiment described below is an adhesive strip, provided that it is on the inside of the outer packaging is provided, preferably in an upper region, in particular provided above a tear strip. Thus located the adhesive strip is in an area of the outer packaging, The total is removed when opening the package and hence the adhesive strip for resealing the inner packaging can be easily removed.

alternative Embodiments are, on the inner packaging a Velcro closure, in other words a closure on the Base of hooks and loops, available under the brand Velcro, to use. For example, on the inner packaging at an increasingly to be emptied upper area a largely from top to bottom on the inner packaging extending strip with hooks or loops and at a lower area and one opposite side a strip with the pendant, so loops or hook, be provided. As a result, the increasingly emptied Inner packaging rolled up at its top and the Velcro be used for reclosing. This is similar Way for that alternative embodiment, in the case of the inner packaging at least partially, for example in the form of a largely extending from top to bottom Strip, a preferred in the initial state, for example by a strip of material covered strip of pressure-sensitive Adhesive is provided, "on" the upper, increasingly depleted area of the inner packaging pressed can be so that it is liable for reclosing it.

in the Regard to such an adhesive, but also the preceding and subsequently described as preferred adhesive strip was for Adhesives, for example, from the companies Tesa, Polygrafica or Avery Dennison are available, found that they are the ones necessary for resealing Have adhesive properties. These consist in particular of the necessary adhesive force even with repeated resealing and to maintain in the refrigerator when storing the package. On the relationship between inner and outer packaging it should be mentioned that this in the inventive Packaging means that each inner packaging is provided with an outer packaging is, and that is not several resealable inner packaging in a single outer packaging. In that regard, can the packaging according to the invention also as a two-ply or layered, and the described, inexpensive To produce structure of a package can be in an advantageous manner to be kept. Furthermore, the outer packaging may be referred to as an "outer wrapper" become. This applies equally to the alternative Inventive embodiment, in the inner packaging is a vacuum packaging and two or three more inner packaging with a single outer packaging can be provided.

advantageous Further developments of the packaging according to the invention can be found in the further claims.

For the use of the adhesive strip for resealing on the part the consumer, it has proven to be advantageous with this at least to provide a non-adhesive edge area. At this non-adhesive edge region of the adhesive strip can be easily grasped and put into use for resealing become.

As already indicated, is preferred for inner packaging, that this consists of a foil, and the food in the Inner packaging is preferably vacuum-packed. From a slide leaves On the one hand in a simple and proven way the preferred produce cuboid inner packaging, and on the other could reseal for the on the slide used adhesive strips good and permanent adhesion values determined become.

For The outer packaging is currently preferred to that preferably coated paper. For example, by a silicone coating results in a pleasant feel of the product and the possibility of having the outer packaging with any To print information.

As already indicated, is the packaging according to the invention preferably cuboid, and for the means for Resealing, especially the adhesive strip is in this case it is preferred that it be in the initial state on a narrow Side surface is provided. The printing of the outer packaging is preferably provided so that the product is upright and thus stands on one of the two smallest side surfaces. A the largest side surfaces forms above it in addition, usually the front, and the adhesive strip to reseal is preferred on one of the remaining "side" side surfaces intended. This offers the advantage that it is not folded through Gusset is concealed, usually at the top the packaging is formed. At the top of the packaging namely, extends between the front and back a suture that leads to two lateral gussets, either on the top of the package or the front and back folded. In both cases, the side-mounted Adhesive strips remain uncovered for resealing and is thus in view of its usability and including the information provided to the consumer, who has already opened the outer packaging, immediately apparent.

The properties of the product according to the invention are further improved by the measures preferably provided, according to which the inner packaging has at least one air feed opening, which is closed in the initial state by the adhesive strip. Due to the fact that the invention If the packaging is closed under vacuum, the inner packaging is comparatively hard, and the previously mentioned gussets or seams, which are to be opened or cut to open the inner packaging, are relatively difficult to expose. This is improved by the said measure by allowing air into the package at the time of opening the inner package to make it "soft". As a result, those areas which are to be opened or cut to open the inner packaging can be easily grasped, and the opening of the packaging is facilitated. In addition, not only air enters the package through the opening of the air supply port, but the aroma of the packaged food, such as coffee, can leave the package through this opening, allowing the consumer a pleasant perception as the package is opened on the aroma of the food. As regards the latter measure, it should be noted that it is independent of all the abovementioned measures, and in particular the presence of an outer packaging, and even without these features has its advantages with regard to the opening characteristics and the flavor which spreads in the process. Advantageously, however, the feature last described can be combined with all the features of a package described above and below. Special synergy effects result from the use of a single measure, namely the adhesive strip both for reclosing the packaging and for closing the air supply opening in the initial state. Thus, both the opening properties and the properties can be improved in terms of preserving the aroma and the freshness over the life.

The Solution of the above object is further by the machine described in claim 7. Consequently, this indicates in this order along the machine direction, ie along the Passing the materials involved, a device for application a reclosing means, in particular one Adhesive strip on an inner packaging and / or on the inside of the Outer packaging and a device for attaching exactly one Outer packaging around the exact inner packaging. Experiments have shown that with such a machine while maintaining the comparatively short cycle times of, for example 0.2 seconds, advantageously a two-layer packaging with a means for reclosing the inner packaging provided. Preferred developments of the invention Machine arise on the one hand from the preferred embodiments the packaging according to the invention and are otherwise in the further claims. The following apply all explanations for the adhesive strip for any other means of resealing, in particular as described above.

Although the adhesive strip in principle then also to the inner packaging can be attached, if this already to be filled Pouch is currently preferred, the adhesive strip on to apply an initially band-shaped inner packaging.

As a result, is preferred according to the device for applying the adhesive strip a device for forming the inner packaging into a bag, for example, with the help of a thorn, provided.

It has also proved to be favorable, the adhesive strip from the bottom to the band-shaped in this case To apply inner packaging. This succeeds particularly well one Adaptation to existing packaging machines, as the inside points upwards in these machines.

in principle it is conceivable, the adhesive strip for resealing just before application to the intended size to cut. However, it is presently preferred to use the adhesive strip Cut to the intended size and for example as a result of numerous adhesive strips on a conveyor belt, preferably mounted transversely to the feed direction supplied and accordingly, a device suitable for this purpose provided.

Around to ensure in an advantageous manner that all Packaging with the adhesive strip for resealing is preferred, again in the machine direction, when viewed in front of the device for applying the outer packaging a device for checking the presence / absence provided the adhesive strip. In addition, a device be provided for discharging packaging that the adhesive strip, for whatever reason, not exhibit.

Corresponding the preferred embodiment of the package in which at least one air supply opening is provided, Preferably, the machine for producing the packaging in the machine direction in front of the device for applying the adhesive strip, a device for punching or cutting at least one air supply opening on. Also, this device is preceded by all and below mentioned features of the described machine independently, However, it can be advantageously combined with these.

Furthermore, with the application, a method provided for the production of a packaged food, the process steps of which are preferably provided partially result from the description of the packaging and / or machine according to the invention. Finally, with regard to further features of the packaging as well as the machine and the method for its production, the content of the following applications of the Applicant is made the subject of the application: EP 1 749 751 A1 . EP 1 882 581 A1 and EP 1 772 380 A1 , In other words, all the features disclosed in the cited documents of the packaging, the machine for its manufacture and the method used in this case are applicable to the packaging, machine and method described herein.

Brief description of the drawings

following is a preferred embodiment of the invention explained in more detail. Show it:

1 a perspective view of the package according to the invention with exposed adhesive strip for resealing;

2 a perspective view of the resealed packaging; and

3 a schematic representation of a portion of the machine according to the invention.

Detailed description preferred embodiments of the invention

As in 1 to recognize, is the packaging according to the invention 10 essentially cuboid and usually provided so that it stands upright on one of the two smallest side surfaces. One of the two largest side surfaces 12 The front and the other of the two largest side surfaces form the back. In the in 1 As shown, the outer packaging is approximately in the lower two-thirds of the packaging 14 to recognize. The top of this outer packaging has already been removed to open the package as a whole. This is done by opening the inner packaging 16 , which is typically made of a film that has been formed, for example, around a mandrel, seamed at the side and at the top or bottom, was subsequently filled and vacuumed. Finally, the filling opening was closed.

In the embodiment shown, a seam extends 18 between the front 12 and the back. This seam forms two gussets in view of the overall roughly cuboidal packaging 20 off, in the example shown to the front 12 and the back are folded. You can, however, also on the top 22 be folded.

At a "side" side surface 24 is the adhesive strip according to the invention 26 intended for reclosing. This is approximately rectangular and may for example have a length of 75 mm to 80 mm and a width of 20 mm to 25 mm. At least one edge, in particular according to 1 For example, the upper edge may be provided with a non-stick area extending, for example, 10 mm across the entire width of the adhesive strip to facilitate gripping of the adhesive strip. The gripping of the adhesive strip is intended to bring it into use for resealing. In the embodiment shown, the adhesive strip is mounted substantially vertically in the upright package, but it may also be mounted substantially horizontally. First, the seam is usually used to open the package 18 in which two gripping tabs can be provided at the outer upper end of the packaging, separated. Alternatively, the packaging may be below the seam 18 be cut open. In the preferred embodiment described above, below the adhesive area of the adhesive strip 26 an air supply opening may be provided by releasing the adhesive strip 26 from the inner packaging 16 is opened to allow air to flow into the vacuum packaging. This will make the package "soft" and the opening described above at the seam 18 is relieved. After opening and removing the desired portions, it is advisable to put the inner packaging in the direction of the front 12 or roll up the back as these are the wider sides.

In 2 this rolled-up state is shown. In 2 It can also be seen that the adhesive strip 26 from its original in 1 shown position to the front 12 has been added to the rolled-up top of the package 10 with the lower area of the packaging still filled with product 10 to connect and thus re-close the package after the first opening.

In 3 is shown schematically a part of a machine for producing the packaging according to the invention. Here is the slide 28 for the inner packaging in tape form of a roll 30 handled by different roles. In a dedicated station 32 becomes a profile section and at a station following in the machine direction 34 a region-wise straight cut made. Subsequently, according to a preferred embodiment of the invention by a suitable device 36 a punching, cutting or an in sons tiger suitably form at least one air supply opening. This is subsequently closed by an adhesive strip, which by a suitable device 38 is supplied and applied. Out 3 it can be seen that this is done from the bottom. To the supply of the adhesive strip it should be mentioned that this is preferably done as a ready-cut adhesive strip and mounted transversely on a feed belt. Between the individual adhesive strips, a comparatively small distance of, for example, 4 mm and at the lateral edges a likewise very small distance of, for example, 1.5 mm may be provided.

By This machine can thus without significant alterations to existing Machines the packaging according to the invention are produced, with the reclosing of the advantageously opened packaging is allowed. This avoids for the consumer the need for the contents of the packaging to recycle into another container, whereby Aroma is lost. Rather, the inventive Packaging in the opened and reclosed condition also over stored for a long time, for example in the refrigerator without significant loss of flavor.
