Description

The The present invention relates to a reclosable package, with a packaging body, with one enclosing a packaging opening Edge component, which is permanently connected to the packaging body, and with a lid held on the edge component and closing the packaging opening; the packaging body at least in a section of the edge receiving portion substantially from a flexible packaging film is formed, wherein the lid in the first-closed packaging state through a first detachable Connection in the form of a bond or seal with the edge component connected and in a resealed packaging state after opening for the first time a separate from the first compound formed second releasable and recoverable connection is connected to the edge component.

A Such packaging is known for example for coffee pads in the market. This packaging is almost entirely made of flexible plastic film, more precisely a plastic film laminate formed.

Of the Lid of this packaging is a dimensionally stable component made of thermoplastic Made of plastic.

to Reinforcement of that section of the packaging which covers the lid is to take a, is also made of thermoplastic material made annular dimensionally stable edge component to the film laminate of the packaging body with so chosen Pressure and temperature sealed that the dimensionally stable edge component when used as intended the package insoluble with the packaging body foil connected is.

Of the Lid in turn is with a plug portion in the edge of the component defined packaging opening plugged in and there by clamping due to material elasticities and Held friction.

at a first-closed packaging, that is to say a packaging, which filled and sealed, but not yet by a consumer open was, the lid is additionally through Ultrasonic welding process sealed to the edge component to a high degree of sealing and closure security to reach.

adversely at the known resealable packaging is their difficult processability during their production.

So on the one hand the strength of the seal between the lid and edge component only with difficulty reproducible, which sometimes closed first Lead packaging can, at which the strength of the seal between edge component and lid is bigger as the material strength of the lid itself. In the consequence can it unwanted Way happen when tearing open the packaging of the lid destroyed will, while Cover sections still adhere to the edge component.

Furthermore it also happens with the unsolvable Sealing of the edge component to the packaging film to film problems which the packaging body film straight through the sealing tool on the outwardly facing presentation surface of the packaging body impaired can be.

For example it may be a local sticking of the packaging body film on the sealing tool come, whereby the lifting of the sealing tool from the packaging body film be pulled out of these threads after successful sealing. Thereby can form material deposits on the sealing tool, which undesirable in subsequent sealing operations Be transferred to subsequent packaging. This threadline can by change be counteracted by sealing parameters, but then at the Sealing to leaks between the packaging body and can lead to the separately formed dimensionally stable edge component.

It It is therefore an object of the present invention to provide a resealable package specify the type mentioned, in which the described Problems are reduced or even completely avoided.

These The object is achieved by a generic resealable packaging, in which the lid in a resealed packaging state the packaging opening piercing plug portion and one insoluble with the plug portion connected flexible lid sheet, of which a joint portion in the first-closed packaging state with the edge component under Formation of the first detachable Connection is connected and the plug section in the resealed Packaging state with the edge component the second detachable connection forms.

With The plug portion of the lid is reclosable the packaging ensured. The plug portion becomes this simply in the packaging opening pressed.

The cover sheet permanently bonded to the plug portion allows the first releasable connection of the cover to be made Edge component by gluing and / or sealing the joining portion of the lid film to the edge component. Due to the great process reliability and the permanent connection of lid film and plug portion is formed by gluing and / or permanent sealing.

Of the Plug portion, which in the hitherto used in the prior art solution then when the adhesive forces the first detachable connection were higher as the material strength of the lid, often with the entire lid destroyed, namely torn was, remains in the proposed inventive solution at Rip preferably peelable (Peelbar) glued by means of the lid film on the edge component and / or sealed lid healing.

Even if the lid foil is destroyed when the packaging is opened for the first time should the plug section remain as a preferably one-piece component, in particular of injection-molded or thermoformed thermoplastic Plastic, whereby the packaging safely reclosed can be.

In As a rule, the lid is in the first-closed packaging state additionally to the first connection also through the second connection to the rest Packaging kept. However, this is not absolutely necessary.

As a "foil" in the sense This application applies such films up to a foil or Laminate thickness of 250 μm.

Strict to distinguish films in the context of the present application are so-called rigid or dimensionally stable plastics, which although under the action of elastic deformation, but overall dimensionally stable are.

Basically be thought of that the edge member formed integrally with the packaging body is. Preferably, however, the edge component is a separately formed component.

A defines peelable first connection between the lid foil and The edge component can be obtained by the edge component is formed from a flexible edge component film, which with the Packaging body foil in the area the packaging opening unsolvable is connected and which with the cover film by peelable (peelable) bonding and / or sealing, as the first detachable connection connected is.

Thereby, that the edge component, as well as at least the edge component carrying the Section of the packaging body, is made of a film, a normal consumption of the Packaging insoluble Connection of the edge component with the packaging body film as well as the first releasable Connection, achieved in particular by sealing, almost without problems become. Just connecting two foils together by sealing is known in packaging technology and is mastered.

Furthermore the use of a marginal component of edge component film is essential cost-effective as the use of the known from the prior art formablablilen thermoplastic edge component.

Surprised has been shown to be even using a foil-like Edge component instead of the previously used dimensionally stable edge component along with the packaging body film sufficiently dimensionally stable packaging body section for definition the packaging opening and can be formed for receiving the lid. This was through the use of intrinsically formlabile starting components not expected.

If Furthermore in the present application of strength and strength compounds, such as a detachable or a permanent connection, so it is always the strength, resilience or (un) solubility when used as intended the packaging designates.

When Adhesive for producing a detachable connection of the cover film with the edge component can be a cold, d. H. at ambient temperature, adhesive glue or alternatively a heat sealing lacquer may be used.

Prefers However, the lid film is sealed to the edge component, d. H. Surface areas of the Edge component and the lid foil, which in the first-closed Packaging state are arranged adjacent to each other, be melted and then sealed together with pressure. If appropriate Choice of material and choice of sealing parameters such as temperature, pressure and time can be the lid, similar as you would expect from tear-open packaging for yogurt, Quark and the like knows to be peeled off the edge component. Such a compound is also referred to in the art as a "peelable" compound.

Then, if to ensure a particularly high degree of closure of the lid in the first-closed packaging state is connected by two releasable connections with the edge component, namely with the first releasable connection between the lid film and edge member and with the second releasable and recoverable connection between edge member and plug portion, while deleted in the resealed packaging state, the first releasable connection, a higher opening force is required to open the first-sealed packaging than to open the only resealed packaging.

Then, if the edge component, in particular as a film component, a first Edge component section has, which is directly insoluble with the packaging body foil is connected, and has a second edge component section, which only indirectly over the first edge component portion with the packaging body film is connected, the edge component on the one hand reliably insoluble with the packaging body film are connected and just as reliable provide a portion with which the lid releasably connectable is.

Preferably is the second, not directly connected to the packaging body film edge component section from the packaging body film from. As a result, especially when the edge component of the edge component film is formed, on the one hand in a very simple and straightforward way in the area immediately around the packaging opening, in which the packaging body formed with the edge component substantially only of sheet material is the rigidity and stability of the packaging considerably elevated become.

To the another may be with the second projecting from the packaging body film Edge component section even with otherwise very slim packaging a sufficient joining surface for Connection with the lid, more precisely with the lid foil provided become.

Basically be thought of the plug section with a suitable choice of material as an injection-molded component or thermoformed component made of thermoplastic Plastic to connect directly with the lid film, especially preferably in turn by thermal sealing. Surprisingly, however shown that also the plug portion at least partially, preferably completely, may be formed from a plug portion film.

Especially when the edge member having a first edge component portion with the packaging body foil is connected while a second edge component portion of the packaging body sheet protrudes, the lid with lid film and plug section covered on an envelope of the Total packaging to be recessed when one with the first Randbauteilabschnitt connected packaging body portion at erstverschlossener Pack the over the edge component to the outside protruding cover portion projecting in the direction of priority. There are fewer possibilities an unwanted and uncontrolled external force the lid, in particular on the plug portion, as in the case a transport of the packaging.

To the Purposes of both securing the lid and providing it of sufficient dimensional stability in the packaging opening close Close the area of the packaging the first and the second edge component section at least in sections, preferably longitudinal their entire extension, an angle, preferably one right angle. Likewise closes Advantageously, the second edge component section at least in sections, preferably along the entire extension of the edge component an angle, preferably one Right angle, with the packaging body.

The Edge component is advantageously designed as a closed ring, the radially inner edge forms a boundary of the packaging opening. Then in the previous paragraph with "extension" is the extent extension meant.

This Ring is preferably annular, however, this does not have to be the case. The edge component can as well an oval (elliptical) shape or a polygonal shape or a Combination of round and polygonal shapes.

In In this case, preferably, a radially outer portion of the annular edge member the first edge component portion while a radially inner portion of the edge component is the second edge component portion.

to preferably good connection of the edge component with the packaging body film is the first edge component section in the case of a peripheral edge component also circulating.

to preferably good shielding of the packaging volume enclosed by the packaging against influences the outside environment, which could spoil the packaged goods may be in that at least one film consists of the packaging body film, the lid film, the edge component film and the plug portion film is a laminate of at least two film layers is, of which a layer forms a barrier layer.

Barrier layers are known per se in the prior art. For this purpose, about EVOH, SiO _x , AlO _x and the like come into question.

In order to shield the packaged goods not only against gases such as oxygen and hydrogen, but also from exposure to UV rays lock, the barrier layer is preferably a metal layer, more preferably a metallized layer. Here, aluminum has proven particularly useful as a material for an absolute barrier.

The Metal layer can be formed by adhesion intermediate layers with adjacent layers connected to the laminate.

Preferably are the packaging body foil and the edge component film provided with a barrier layer, especially preferably also the lid foil. To ensure a possible good barrier effect can also stopper section foil a Have barrier layer.

to preferably simple connection of the films with each other can alternatively or additionally provided be that at least one film from the packaging body film, the lid film, the edge component film and the plug portion film a laminate of at least two layers of film, of which at least an outer layer, preferably both outer layers, are formed by a sealable thermoplastic.

Especially all four are preferably involved in the packaging described here Foils with two outside each lying layers of sealable thermoplastic material provided.

There both the edge component film and the cover film one each unsolvable and a detachable connection are to be received, is provided in a preferred embodiment of the invention, that at least at the edge component film or at the cover film, preferably in both films, particularly preferably also the plug section film, an outer layer from a sealable thermoplastic to form insoluble compounds suitable is. Such a plastic is for example polypropylene (PP). And it is further provided that each other's outer layer from a sealable thermoplastic to form a releasable Compound, in particular a peelable compound is formed. Such a plastic is for example oriented polypropylene (OPP) or PP-peel.

One another important point for Packaging is their printability. To ensure, that the resealable Packaging is printable with consumer information and the like, it can be provided that at least one film from the packaging body film, the lid film, the edge component film and the plug portion film a laminate of at least two layers of film, of which at least a layer is formed for receiving printing inks. This can be especially a layer of a polyester, in particular of polyethylene terephthalate (PET) be provided. The PET layer can also increase the laminate stiffness be provided.

alternative or additionally can also the outer layer, in particular the OPP outer layer, to protect the ink application by reverse printing or without special Protection simply printed by imprinting.

The compatibility of packaging body foil and / or edge component film and / or cover film and / or plug portion film as well as their material properties can then be substantially similar or even be set the same if the films mentioned essentially include same layers.

Especially Preferably, they have the same layer structure, d. H. documents made of the same material are arranged in the same order in the laminate.

Out cost reasons Particularly preferred are the packaging body film, the lid film, the Edge component film and the plug portion film substantially identical. Then a film can be used both for the formation of edge component and packaging openings packaging body be used.

to Achieving the best possible Barrier property of the packaging can be provided that the Cover film spans the plug section. Because of that Cover film spans the plug portion, so from the interior When viewed from the outside of the packaging, the lid foil in the first-capped one provides Condition with suitable choice of film for a suitable barrier, in particular absolute barrier against gases and / or light, so that the plug portion of a cost-effective material without barrier properties can be produced.

By the spanning the plug portion through the lid film can also the entire cover surface be printed, if the lid film with the aforementioned, ensuring the printability Features is provided. For secure attachment of the lid film On the edge component can be provided that the lid film in their Extension plane in at least one spatial direction a larger dimension has as the plug portion. So this means that the lid foil protruding beyond the plug section in at least one of its planar extension directions, so that the lid film especially if the edge component the above mentioned Edge component film comprises, very simple and reliable with the edge component solvable can be connected.

Prefers has the lid film in its plane of extent in at least two mutually orthogonal spatial directions larger dimensions than the Plug section, resulting in a safer connection of the lid film allows with the edge component.

According to one particularly preferred embodiment The present invention provides that the plug portion along a longitudinal axis extends and the lid film based on the plug portion the longitudinal axis radially outside surrounds. The plug portion often has a cylindrical or similar shape Shape up, d. H. He has a lateral surface, along which he rests on one edge of the package opening rests and thereby closes the packaging opening. These lateral surface extends in the axial direction to the plug portion of the for a Introduce into the packaging opening to give necessary axial expansion.

Then, when the lid film surrounds the plug portion radially outward, the plug portion can be completely removed from the first sealed package Be surrounded by a film, so that at least in the packaging opening section Completely printable and / or full surface equipped with a barrier packaging can be achieved.

Of the Plug portion is then through the outside surrounding foils: packaging body film, Cover film and possibly edge component film, as it were packed with. Therefore it depends on the barrier and printing properties of the stopper section not necessarily on.

to resealing the packaging may be provided that the plug portion then, if the packaging opening closed by the lid, at a radially inner edge of the Edge component abuts.

As already mentioned the lid can be particularly easy with the remaining packaging connected when the joining section the lid foil surrounds the plug portion of the lid radially outward. Then, in particular, the joining section a flat Abut portion of the edge member while the plug portion rests against the radially inner edge of the edge component and thus the of the defined by the radially inner edge of the edge component packing opening.

Especially in the reclosed packaging state, the lid can secure the packaging opening and close tightly enough, though the plug portion by a material elastic clamping and the friction caused thereby is held by the edge component.

A Such material elastic clamping can, for example, characterized that the edge component forms an edge of the packaging opening, wherein dimensions of the plug portion are greater than associated dimensions of Package opening.

Make associated "dimensions" doing the dimensions of those sections of edge component (for definition the packaging opening) and plug section, which with correctly resealed packaging interact with each other in plant interaction.

at a plug portion with a circular cross-section and a package opening with circular Cross section are the assigned dimensions the respective diameters from plug portion and packing opening.

in the Trap of elliptical cross-sections of plug portion and packaging opening for example, the two small semi-axes and the two major semi-axes the respective elliptical cross sections associated with each other.

to Formation of the aforementioned lateral surface, the plug portion advantageously have a jacket portion, which is extends away from the lid film at a predetermined angle. Preferably, the shell portion extends below a right Angle away from the lid film or is at least partially light conical, d. H. formed in the direction tapering away from the cover film, for an introduction of the jacket section in the packaging opening for abutment of the lateral surface of the radially inner edge of the packaging opening easier.

to preferably safe and tight installation of the stopper section on the lateral surface of the Jacket section can this with respect to a plane of extension the lid foil orthogonal reference axis along a closed path be formed circumferentially.

from time to time it may be sufficient that the plug portion only from the shell portion exists, d. H. that the plug portion of one of the lid film at an angle protruding ring or hollow cylinder and the like is formed. The outer shape the shell portion, so the shape of the lateral surface is to achieve as much as possible sealed packaging in the resealed packaging state of Contour of the radially inner edge of the packaging opening designed accordingly. This means the lateral surface on the mantle section can be a circular, elliptical or polygonal Have cross-section or mixed forms thereof.

to Receiving materials, which are initially the contents of the resealable packaging according to the invention can be provided separately, it can be provided that with respect to the above reference axis radially within the Sheath portion located wall portion of the plug portion together with the shell section and the lid foil a storage space encloses.

This Storage space may be in accordance with a preferred development of the present invention used be, so-called scavenger materials which are adapted to gases, such as oxygen or / and ethylene, or / and liquids, such as water, to absorb or bind to the actual Contents of the packaging according to the invention preferably long before unwanted external influences to protect the to be absorbed or bound.

to particularly durable and secure connection of the lid foil with the plug portion can also be remembered that a respect the reference axis located radially within the shell portion Wall section of the plug portion with the lid film, preferably unsolvable connected is. Preferably, the runs Wall section thereto at least partially parallel to the lid film.

In addition, can it may be he wishes be the contents of the previously described memory space for users accessible close. Therefor can be provided that the wall portion by a with the end portion of the skirt portion remote from the lid sheet, preferably solvable, connected, preferably connected by sealing cover sheet is formed.

to preferably safe reclosability the packaging according to the invention can be thought of that the shell portion at least along one Peripheral portion, preferably completely encircling, a related Having on the reference axis nachradial outside projecting Verrastungsaustülpung.

In order to the plug section nevertheless without major difficulties in the Can be used packaging opening is, the reclosable package described here so on be formed, that the latching protuberance based on the opening area of the package opening having an inclined insertion slope, which an introduction the plug portion in the packaging opening for the preparation of reclosed packaging condition easier.

Around either the contents of the storage space already before opening the packaging accessible to make or only the plug section, in particular his Mantle section, as a stacking aid when stacking several similar reclosable packaging according to the invention to be able to use can the packaging according to a preferred embodiment be formed further characterized in that the shell portion in the first-closed Packing condition in direction of the packaging interior away from the lid sheet protrudes, preferably at one in the first closed Condition with a side facing away from the packaging interior of the Lid-film undetachably connected is.

Preferably is for cost reasons the entire packaging body formed from foil laminate. Here are mainly cylindrical packaging body as with simple means of form-stable films buildable dimensionally stable packaging body proved.

Begrudge is that the packaging according to the invention according to a advantageous development for easier first opening so can be configured that the lid film as a tear a tear tab which preferably has an outer edge the packaging projects to be gripped by a user facilitate.

In addition, can be provided for easier stacking of the packaging, that the lid film in the first-sealed packaging state in Essentially is just. This can especially the plug section far enough into the packaging opening sunk into it and / or from a sufficiently thin film laminate be formed so that it does not stick to the lid or barely even if it is already in the first sealed packaging state is arranged.

The The present invention will now be described with reference to the accompanying drawings be described in more detail. It shows

1 a cross-sectional view of a closure portion of a first embodiment of a resealable packaging according to the invention.

2 a cross-sectional view of a closure portion of a second embodiment of a resealable packaging according to the invention.

3 a cross section through that in the packaging of 1 and 2 used foil laminate.

In 1 is an inventive embodiment of a resealable packaging in general with 10 designated. The packaging 10 , of which only the closure portion is shown, is rotationally symmetrical with respect to the axis of rotation Z. The cross-sectional plane of the representation of 1 contains the rotation axis Z.

The packaging 10 comprises a cylindrical packaging body 12 from a packaging film 13 , at one axial longitudinal end thereof 12a on the inside 12b a border component 14 is permanently sealed.

The one from a marginal component foil 15 formed edge component 14 , which is made of the same film material as the packaging body 12 , is in a first edge component section 14a with its outside 14b to the inside 12b of the packaging body 12 permanently sealed over the entire common axial and radial extension length. Alternatively, this compound could be formed by gluing instead of thermal sealing.

A second edge component section adjoining the first edge component section in the radial direction 14c is orthogonal to the cylindrical packaging body 12 radially inward, ie towards the axis of rotation Z, from.

The edge component 14 is formed from an initially substantially planar annular piece of film which extends in the radial direction over the common length of the first edge component section 14b and the second edge component section 14c extends. The first edge component section 14a So when inserting the edge component in the cylindrical inner surface 12b of the packaging body 12 forcibly into the in 1 transformed position have been transformed.

A radially inner edge 14d of the edge component 14 defines in the undeformed state a packaging opening 16 through which the interior 18 the packaging 10 is accessible from the outside.

The packaging 10 is in 1 shown in its first locked state, ie it is in a state as it leaves the filling station of a packer towards the consumer.

In this first locked state is the packaging opening 16 (the position of the radially inner edge 14d of the edge component 14 with undeformed second edge component section 14c is in 1 indicated by dashed lines) through a lid 20 locked. A dimensionally stable plug section 20a of the lid 20 penetrates the packaging opening 16 and lies under material elastic deformation of the second edge component section 14c on the edge 14d of the edge component section 14 at.

Already by this material elastic deformation and thereby caused friction is the lid 20 safely on the edge component 14 held. The achieved by the material elastic deformation clamping of the lid 20 on the second edge component section 14c ensures the reclosability of the packaging 10 after the first opening.

The plug section 20a further includes a radially outwardly projecting circumferential connecting portion 20b on. This connection section 20b runs substantially parallel to the plane of extent of the second edge component section 14c ,

At the side facing the edge component side 20c of the connection section 20b is a lid foil 22 imperviously sealed. The connection of the lid foil 22 with the connecting section 20b the plug section 20a In terms of its strength, this corresponds essentially to the connection of the first edge component section 14a with the longitudinal end 12a of the packaging body 12 ,

The lid foil 22 is made of the same sheet material as the packaging body 12 and the edge component 14 the illustrated embodiment. The lid foil 22 which the plug portion 20a of the lid 20 closed surrounds, is located over almost the entire circumference of the lid 20 under the connecting section 20b , Only at the in 1 drawn spot has the cover sheet 22 an opening tab 22a on which gripped with fingers and to release the connecting section 20b from the second edge component section 14c can be used.

The lid foil 22 is with her from the connecting section 20b away side 22b to the outward-facing side 14e of the edge component 14 detachable, more precisely peelable (sealed). The at the edge component foil 15 adjacent and peelable sealed area of the lid film 22 defines their joining section 22d ,

With its opposite outside 22c On the other hand, it is, as already mentioned above, insoluble in the surface by thermal or ultrasound-initiated sealing 20c of the connection section 20b connected.

For the first opening by the releasable seal of the edge component 14 with the lid foil 22 and by the permanent sealing of the lid foil 22 with the lid 20 hermetically sealed packaging 10 becomes the lid foil flap 22a firmly gripped between two fingers and in axial Direction from the packaging body 12 Get dressed. This will make the lid film 22 from the edge component 14 peeled off and the stopper section 20a from the packaging opening 16 pulled out.

The plug section 20a can if desired reclosure of the packaging 10 under deformation of the edge 14d near area of the edge component 14 be pressed into the packaging opening, and close this.

The plug section 20a is then by the material elastic deformation of the edge component 14 and thereby between the edge component 14 and the plug portion 20a reasoned friction held on the packaging.

Due to the permanent connection of the first edge component section 14a with the axial longitudinal end region 12a of the packaging body 12 this becomes the longitudinal end region 12a containing axial longitudinal end of the package 10 considerably stiffened, so that the packaging opening 16 near the packaging area 10 during an opening operation and in the open state substantially retains its shape.

To protect the lid 20 against unwanted force and thus unwanted opening, such as during a transport process of the packaging 10 , overhang both the longitudinal end region 12a the packaging body as well as the first edge component section 14a in the closed state of the packaging 10 the lid 20 in the axial direction to the outside.

The plug section 20a has a substantially parallel to the axis of rotation Z extending shell portion 20f on. This coat section 20f closes immediately to the connecting section 20b the plug section 20a at.

Dashed line is at the radially outer portion of the shell portion 20f a circumferential around the rotation axis Z radial protuberance 34 of the jacket section 20f shown, which is adapted to the radially inner edge 14d of the edge component 14 to fall behind in the manner of a catch. To insert the plug portion 20a in the interior 18 the packaging through the packaging opening 16 through is at the radial protuberance 34 an insertion bevel 34a formed, which also rotates about the axis of rotation Z. This insertion bevel 34a is located radially inward to the area of the material section 20f into it.

The plug section 20a can, as otherwise shown in a solid line, pot-like with a to the plane of the packaging opening 16 substantially parallel wall section 20g be formed, which adheres to that of the lid film 22 far end of the jacket section 20f connects to this.

Alternatively, the shell section 20f also bead-like according to the dashed line with the name 20f ' be educated. In this case, the shell section 20f a U-shaped cross-section in a cross-sectional view containing the axis of rotation Z, wherein the radially inner wall portion 20g ' approximately at the height of the connecting section 20b is located.

The wall section 20g respectively. 20g ' fills the entire radially inside of the shell section 20f respectively. 20f ' lying portion of the plug portion 20a out, leaving this the packaging opening 16 can close tightly.

In the 1 However, the packaging shown has a drawback in that the only part of the plug 20a closed area of the packaging 10 does not ensure sufficient barrier properties since it is at the plug portion 20a is merely an injection molded thermoplastic component. Depending on the packaged goods, however, increased barrier properties or packaging provided with absolute barrier properties may be desired.

The same applies if the packaging is essentially complete, in any case also in the Cover area, to be printed or at least printable.

To overcome these disadvantages, the in 2 shown particularly preferred second embodiment of a package according to the invention proposed.

In the 2 illustrated embodiment in which the same or functionally identical components as in 1 with the same reference numerals, but increased by the number 100 are described in the following only in so far as it is different from the in 1 differs in the first embodiment shown, to the description of which reference is expressly made.

At the in 2 illustrated second embodiment is the plug portion 120a essentially identical to the plug section 20a the first embodiment in the packaging opening 116 is introduced and is in the first as in the resealed packaging condition of the deformed edge component 114 More specifically, by a contrary to their material elasticity widened edge component film 115 kept there.

However, spanning in 2 the lid foil 122 the plug section 120a of the lid 120 ,

The lid foil 122 is this with her page 122b with which she peelable to the side 114e by the edge component film 115 formed edge component 114 sealed is insoluble to the side 120e of the connection section 120b of the lid 120 sealed.

The different strengths of the compounds of the cover film 122 with the edge component 114 on the one hand and with the plug section 120a on the other hand, it is possible to set by varying the temperature and / or sealing pressure and / or sealing duration, in which case the bonding strength increases with increasing sealing temperature and / or increasing sealing pressure or / and increasing sealing duration.

Apart from the tab 122a is the lid foil 122 as the connecting section 120b to which it is sealed, is substantially circular, but has a larger diameter than the plug portion 120a or the connecting section 120b on, leaving the lid film 122 with her joining section 122d the plug section 120a completely surrounded radially on the outside. This is the plug section 120a from the film assembly of packaging body film 113 , Edge component film 115 and lid foil 122 completely edged.

The packaging 110 is thus against unwanted opening by accidentally pulling out the plug portion 120a very well protected.

In addition, in the preferred case of a packaging formed solely from the designated films 110 a complete, ie printable on all sides packaging accessible.

As well is a complete, d. H. all-sided, with barrier properties provided packaging achievable.

That from the packaging 110 Packaged packaged goods are thus best protected against influences from the environment.

As in 2 displayed with double-dashed line, the shell section can 120f in that the plug portion 120a completely off the lid film 122 is spanned, as only annular hollow cylindrical shell section 120f '' be formed, which in a rotation axis Z containing a cross section due to the presence of the connecting portion 120b Has L-shaped cross-sectional shape. Then, if the connecting section 120b not radially outward or inward of the skirt portion 120f '' protrudes, the shell section 120f '' also have only a rectangular or parallelogram cross-section in the designated cross-sectional view.

For a particularly secure connection of the lid foil 122 with the plug portion 120a can in the previously described variant of the jacket section 120f with a substantially U-shaped cross-section of the radially inwardly adjoining wall section 120g ' partially or completely detachable or unsolvable with the lid film 122 be connected, more preferably by sealing.

By doing that, the lid foil 122 the plug section 120a spans, then, when the plug portion as in the 1 and 2 shown non-solid, through the plug portion 120a along with the lid foil 122 a storage room 130 enclosed in which materials can be accommodated. These may be in particular so-called scavenger materials, which are used for absorption or binding of the interior 118 the packaging 110 serve unwanted gases and / or liquids.

Alternatively or additionally, it can also be thought of the memory space 130 for users of the packaging 110 to make accessible. For this purpose, in particular when the shell section 120f '' the plug section 120a just as from the lid foil 122 protruding ring is formed, which is attached to the shell portion 120f '' adjoining wall section 120g '' as one to the lid foil 122 essentially parallel, the plug portion 122a on the cover of the film 122 distant end spanning plug portion foil 132 be educated. The stopper section foil 132 in particular detachable to the shell portion 120f '' or generally to the plug portion 120a be sealed, in particular be peelable sealed.

Preferably, the plug portion foil is 132 with at least one, preferably with all the aforementioned films identical, so that needs to be used to form the packaging according to the invention on only a single sheet material.

In 3 the construction of the film is shown in cross-section, which is used to form the packaging body foils 13 and 113 , The Edge Component slides 15 and 115 as well as the lid films 22 and 122 is used.

The film laminate used has a layer as an outer layer 30 detachable (peelable) them gelfähigem thermoplastic material, in the example shown from oriented polypropylene (OPP) with a layer thickness of about 30 microns.

To the outside situation 30 borders a printable, so ink-absorbing layer 32 at. In the illustrated example, this printable layer is formed by a layer of polyethylene terephthalate (PET) with a layer thickness of about 12 microns.

To those of the OPP location 30 away-facing side of the pet layer 32 borders a barrier location 34 at. In the example shown, this is an aluminum layer of about 8 μm layer thickness.

At the of the PET location 32 away side of the aluminum layer 34 finally closes as a second outer layer 36 a layer of insoluble sealable thermoplastic material. In the example shown, the second outer layer 36 formed by polypropylene (PP) with a layer thickness of about 70 microns.

The advantage of this laminate construction is also that in the in 1 illustrated packaging 10 always for the same purpose sealable outer layers 36 or 32 abutting each other to be joined together films and at the same time the ink-absorbing layer 32 further out than the barrier location 34 so that the ink-absorbing layer 32 always perceptible and not from the barrier 34 is covered.

The first edge component section 14a and the packaging body 12 are about the outer layers 36 the films involved inextricably linked.

The second edge component section 14 and the lid foil 22 are over adjoining outer layers 30 the slides involved 15 and 22 Peelable interconnected.

The plug section 20a , which is also made of polypropylene for this purpose, is again on the outer layer 36 the lid foil 22 inextricably linked to this.

Except for the connection of plug section 20a with the lid foil 22 applies to the in 2 example shown the same. There is only the outer layer formed from oriented polypropylene 30 with the connecting section 120b the plug section 120a indissolubly connected, but by the identical choice of material (polypropylene) for this outer layer and the plug section 120a no problems.

In the illustrated examples, the packaging opening 16 ; 116 in the unlocked condition of the packaging 10 ; 110 , So at undeformed second edge component section 14c ; 114 a smaller diameter than that in the packaging opening 16 ; 116 insertable plug section 20a ; 120a of the lid 20 ; 120 , The packaging opening 16 ; 116 Therefore, when pressing the plug portion 20a ; 120a in this against the Materialelastizizät the second edge component section 14c ; 114c widened. The edge 14d ; 114d of the edge component 14 ; 114 is according to the material properties with a caused by this expansion elastic force and thereby further caused friction at the plug portion 20a ; 120a of the lid 20 ; 120 and holds this releasably in the closed position.
