Description

The invention relates to a package for storing a flowable, pasty or powdery substance (in particular a dental substance), consisting of or comprising a bottom sheet and a cover sheet, which are at least partially sealed together, and a removal chamber, the at least partially deductible sealed areas of the bottom sheet and the cover sheet is formed, wherein the removal chamber is openable by peeling off at least a first portion of the cover sheet from the bottom sheet.

Furthermore, the invention relates to a collecting device for storing at least one flowable, pasty or powdery substance and a method for storing and applying a flowable, pasty or powdery substance.

Packaging of the type mentioned are often used in dental technology to provide substances, for example, for the treatment of patients.

DE 81 05 156 U1 describes a Abdeckfolienbahn from which are to be applied to formed on a plastic film web packing cavities cover.

The Abdeckfolienbahn is provided on the upper side and / or underside with the individual lids associated self-adhesive labels.

DE 23 27 206 A discloses a single-dose package, preferably for the administration of medicaments, comprising a lower foil containing a chamber and a sealing foil covering the chamber, and a permanently adhesive marking foil releasably attached to the pack. The marking film is designed as a sealing film, provided with a gripping surface and designed removable at the same time opening the chamber of the package.

WO 00/09416 discloses a package for two-component products and a method for their production. It discloses a package for an epoxy resin and a curing agent including a thermoformed element having two chambers for each epoxy resin and hardener. On the underside of the thermoformed element a foil is laminated to close each chamber. Lamination between the chambers at the interface of thermoformed element and laminated film ruptures when external pressure is applied to one of the chambers. The tearing connects the two chambers and allows epoxy and hardener to be mixed in a closed shell. The mixed adhesive may be withdrawn through a dispensing opening formed by a channel to be broken, which communicates with one of the chambers.

DE 31 22 237 A1 discloses a packaging for liquid filling material, consisting of a deep-drawn part and a deep-drawn part up close sealing cover sheet. In the intermediate space formed between the deep-drawn part and the cover sheet is the liquid contents and an insert (brush, sponge, droppers, plugs, etc.) for dispensing liquid. The packaging has a predetermined breaking point, which is laid in such a way that when the part of the packaging is broken off from the remaining part, the insert part is exposed, so that liquid is discharged through a passage channel from the liquid space through the insert part.

A disadvantage of the in WO 00/09416 and DE 31 22 237 A1 One of the solutions shown is that the entire package must be handled to remove and apply the contents. This is disadvantageous especially in difficult to access applications in the dental field. Furthermore, the speed of removal of the It is difficult to control contents from the proposed packaging and to disperse the amount of removal.

DE 298 14 215 U1 . WO 96/03326 . DE 100 47 679 A1 and EP 0 895 943 B1 reveal packaging with applicators. DE 298 14 215 U1 shows a multi-chamber packaging of a thermoplastic deep-drawn part with at least two wells and a sealed cover sheet. The pack is equipped with a bowl containing a liquid medium. In a second bowl is an absorbent insert. The wells are separated from each other by a region of the web which is peelably sealed to the cover foil. By pressure on the first cup, the peel seal between cover sheet and web between the wells opens and the impregnation medium from the first bowl runs into the second bowl and wets the liner. By pulling on a free peel-off, the cover film which has been peel-sealed at the edge of the deep-drawn part can be pulled open and the impregnated insert removed. As an application part to be impregnated, a rod with an absorbent head can also be inserted into the cup.

WO 96/03326 discloses a tray with wells for receiving a medicament and an applicator. The applicator well has an open end over which a substantial portion of the applicator protrudes. A cover of thin, flexible sheet material seals the entire surface of the tray. The protruding part of the applicator can be used to break the cover. After removing the cover, the medicament can be applied easily and practically, whereby the entire package and the applicator can be disposed of easily after use.

In DE 100 47 679 A1 discloses a device for storing and mixing in particular pasty masses. The device comprises at least one chamber capable of receiving a substance, the at least one chamber being formed by peelably sealing a base sheet and a cover sheet. In the activation of the device by pulling or pulling the cover sheet of the base film takes place in this way, depending on the selected arrangement of the substance to be mixed on the base film, a division on the exposed, largely flat mixing area into two separately miscible portions.

In the DE 298 14 215 U1 . WO 96/03326 and DE 100 47 679 A1 have the disadvantage that the film to be removed in the storage state comes into contact with, for example, a flowable or pasty substance and substance residues can adhere to the withdrawn film, which in the handling of the film or the packaging to adhesions or contamination of the environment of the packaging , of devices or users. Breaking or tearing of the film reinforces this disadvantage and can also lead to the fact that the film must be laboriously removed in several, often small items.

EP 0 895 943 B1 discloses a device for storing and dispensing a flowable substance with a container of two foils. The separation between the chambers has a passage area which can be selectively opened by an externally applied pressure, and a chamber is formed as a pocket which is already open outwardly in the storage state at one end. The removal of the substance is preferably carried out by a stored in the bag or by the user in the pocket insertion order tool that can be wetted or brought into contact with the substance without the container is opened altogether.

A disadvantage of this solution that the job instrument must be reintroduced into the tight pocket when the job instrument is to be brought into contact with the substance again. This is cumbersome for a user and can cause substance to adhere to the channel and its mouth, thus becoming unavailable for use and contaminating both the package and its environment.

In your own EP 1 153 579 B1 a device for storing and applying one or more component flowable dental materials is disclosed. A trough for receiving a substance is closed with a foil. The film can be pierced with a suitable application device to subsequently remove the substance from the trough.

From your own DE 102 43 401 A1 In addition, a package for storing at least two substances in separate chambers is known, wherein the chambers are formed of liquid-tight sealed portions of a bottom sheet and a cover sheet and sealed in a chamber connecting the area the bottom sheet and the cover sheet to each other so that by applying a pressure from the outside on the first chamber in the said region selectively detach the sealing connection between the films, form a passageway between the first and the second chamber and the first substance can be transferred from the first to the second chamber. The cover sheet in an area associated with the second chamber, which has a material weakening, is pierced and the substances mixed before or after the piercing are removed. For piercing the cover film and advantageously also for mixing and removing the substances, an application device with an application tip can be used.

While these are in EP 1 153 579 B1 and DE 102 43 401 A1 disclosed solutions are suitable and advantageous for use in the dental field, but it may be advantageous in individual cases to allow the removal of substances without puncturing a film, for example when using a not suitable for piercing a film application device.

The primary object of the invention is to provide a package whose handling is simplified or improved. A further object of the invention is to specify a packaging which simplifies or improves the removal or the application of at least one substance contained in the packaging. It is a further object of the invention to provide a package which simplifies or improves the dosage of at least one substance contained in the package.

The object is achieved by a package for storing a flowable, pasty or powdery substance, consisting of or comprising a bottom sheet and a cover sheet, which are at least partially sealed together, and a removal chamber formed from at least partially peelable sealed areas of the bottom sheet and the cover sheet wherein the removal chamber is openable by peeling off at least a first portion of the cover sheet from the bottom sheet, wherein a second portion of the cover sheet arranged adjacent to the first portion has a lower deformation resistance than the first portion of the cover sheet, so that a permanent opening of the extraction chamber required deformation of the cover sheet occurs substantially in the second portion of the cover sheet.

One of the underlying idea of the invention is to use a cover film with sections of different deformation resistance, so as to to influence occurring during removal of at least a portion of the cover sheet occurring deformation of the cover sheet. The inventively provided second portion of the cover sheet of the packaging according to the invention serves as a desired deformation section. It is less stable compared to the first section of the cover sheet against deformation, in particular plastic deformation. Thus, while the first, comparatively stable section retains the first section of the cover film from the bottom film in a substantially planar form or resumes it after elastic deformation, the second section of the cover film deforms, preferably plastically substantially along one narrow, approximately line-shaped area, so that the first portion of the cover sheet can be detached from the bottom sheet. The opening of the sampling chamber is to be understood heretofore and hereinafter as a permanent opening.

The lower resistance to deformation of the first section of the second section of the cover film can be realized by weakening the cover film in the region of the second section or by reinforcing it in the region of the first section of the cover film.

The embodiment of the packaging according to the invention has the advantage that any or at least a strong curling or uncontrolled buckling of the first section of the cover film when opening the packaging can be substantially avoided. The first portion of the cover film remains during removal and preferably also thereafter in the opened state of the packaging dimensionally stable than known cover films, preferably even substantially dimensionally stable. This has the advantage that contamination of the user of the packaging according to the invention, the environment or equipment can be avoided or reduced because on the first portion of the cover sheet adhering substance is less distributed by uncontrolled curling, buckling or bending.

A further advantage of the packaging according to the invention is that the packaging can be disposed of as a one-piece piece after use in one operation, if the cover sheet - as often provided - is not completely removed from the bottom sheet.

The substance to be stored may be any substance, but preferably a dental material. The substance can be considered as one or be formed multicomponent substance, various consistencies such as powdery, pasty, flowable or liquid and contain homo- or heterogeneous dissolved, solid or gaseous components. In particular, the substance may be a fluoride varnish.

In a preferred packaging according to the invention, the deformation occurring in the second section of the cover film when opening the removal chamber is a substantially plastic deformation.

A force required to open the removal chamber in this case causes in the second portion of the cover sheet plastic deformation, which after the action of force, i. after opening the sampling chamber, it remains. A spring back of the first portion of the cover sheet by an elastic reformation of the deformation in the second portion of the cover sheet is thereby substantially prevented. This has the advantage that substance adhering to the first section of the cover film does not come into contact with the user, devices or the environment, in particular when handling the packaging, for example when applying the substance. So adverse soiling or sticking can be avoided.

In a preferred packaging according to the invention, the deformation occurring in the second section of the cover film when opening the removal chamber has a higher proportion of plastic deformation than the deformation occurring in the first section of the cover film when the removal chamber is opened. Particularly preferred is a packaging according to the invention for storing a flowable, pasty or powdery substance, consisting of or comprising a bottom film (120, 220) and a cover film (130, 230), which are at least partially sealed together, and a removal chamber (140, 240 The extraction chamber can be opened by peeling off at least a first section (131, 231) of the cover film from the bottom film, wherein a second section adjacent to the first section is openable Cover film has a lower resistance to deformation than the first portion of the cover sheet, so that a permanent opening of the removal chamber required deformation of the cover sheet occurs substantially in the second portion of the cover sheet, characterized in that in the second portion of the cover sheet when opening the removal chamber (140, 240) occurring deformation a higher proportion of plastic deformation than the deformation occurring in the first section of the cover sheet when opening the removal chamber.

These preferred packagings according to the invention have the advantage that a deformation of the first section of the cover film occurring when opening the removal chamber elastically regresses to a greater extent than the deformation of the second section of the cover film which has a comparatively higher plastic proportion during the opening of the removal chamber. preferably even substantially plastic. As a result, an improvement in the stability of the cover film in the open state can be achieved since the plastic deformation in the second section of the cover film determines the position of the first section of the cover film and the first section of the cover film by the elastic recovery of at least part of its deformation in the cover opened state has a lower overall deformation. These advantages according to the invention are also achieved if a certain, comparatively preferably small, plastic deformation component remains in the first section of the cover film.

Preferably, the second portion of the cover sheet is disposed between the first portion of the cover sheet and a third portion of the cover sheet, and the second portion of the cover sheet has a lower resistance to deformation than the third portion of the cover sheet.

An embodiment in which the second section of the cover film is arranged between the first section and the third section of the cover film is preferred, for example, if the second section should have only a limited extent as a desired deformation section and / or a third section of the Cover film with higher deformation resistance from, for example, production and / or application-specific reasons is preferred.

It is understood that preferred embodiments of the packaging according to the invention, which relate to different features, preferably are present simultaneously, e.g. a plastically deformable second section which lies between a first and a third section.

The first portion of the cover sheet and the second portion of the cover sheet of a package according to the invention preferably have a substantially same Width on and the length of the second portion of the cover sheet is less than the length of the first portion of the cover sheet. In addition, it is preferred that the first portion of the cover sheet and the third portion of the cover sheet have a substantially equal width and the length of the first portion of the cover sheet is less than the length of the third portion of the cover sheet.

A substantially equal width of the cover film sections has, among other manufacturing advantages, since in this way, for example, a continuous cover sheet can be used, which is weakened in the second section or reinforced in the first section and / or in the third section. The second section preferably deforms substantially in a narrow area, therefore a length of the second section correspondingly smaller than the first section is advantageous.

Since the first portion of the cover sheet covers the extraction chamber or releases according to the invention after removal, a greater length of the first portion is advantageous in order to achieve a correspondingly large opening of the extraction chamber and to simplify the handling of the packaging and the application of the substance.

The third portion of the cover sheet may have different dimensions. In a preferred embodiment, it is longer than both the first and the second portion of the cover sheet.

Alternatively or-preferably-in addition to the previously described features of preferred packagings according to the invention for forming different sections of the cover film, in particular the formation of different sections of the cover film with different deformation resistances, preferred packaging according to the invention preferably also comprise the features described below with regard to the formation of covering layers. and / or bottom sheet. Preferably, preferred embodiments of the packaging according to the invention, which relate to different features, are present at the same time.

In preferred packages according to the invention, the cover film comprises a barrier film, preferably a barrier film of metallic material, for example an aluminum foil in a thickness of about 20 μm, or consists of such a barrier layer.

Such a barrier film is particularly preferred if one or more substances are to be stored in the packaging, which contain substances that can diffuse through, for example, plastic. A barrier film is preferably designed such that it prevents diffusion, in particular of gaseous constituents of the substance, through the cover film. A preferred barrier film is designed so that they protect the substance or substances, for example from light.

As a result, the shelf life of the substances is improved and / or extended.

In preferred packagings according to the invention, the cover film in the first and / or in the third section has a reinforcing layer, preferably of plastic or paper.

In addition or as an alternative to a weakening of the second section of the cover film, the first section and / or the third section of the cover film are thus reinforced. Such a reinforcement is preferably applied as a reinforcing layer on the cover sheet. For example, the cover film may be formed as a composite film with at least two composite layers, wherein one of these composite layers represents the reinforcing layer. This reinforcing layer may consist of any materials or combinations of materials, preferred materials are plastic or paper.

It is particularly preferred that the reinforcing layer of the first and / or the third portion of the cover sheet is formed as a printed or unprinted adhesive label.

Adhesive labels are preferably used as the reinforcing layer of the cover film in the first section and / or in the third section of the cover film. This conventional adhesive labels can be used, which has a positive effect on the manufacturing cost. Furthermore, it is advantageous to provide the labels with a print, for example with information about the substance contained and its application, so that a further labeling can be omitted. Adhesive labels additionally have the advantage that no additional adhesive has to be applied to the cover film in order to fasten the reinforcement layer, which can also have a positive effect on the production costs. The choice of adhesive labels is preferably carried out according to the requirements of stability and deformation resistance, Printability and adhesive properties of self-adhesive labels and cover film, in each case in cooperation with the other materials of the cover film.

The packaging according to the invention can be further configured in that the cover film is provided on its side facing away from the bottom film with a corrosion protection, preferably a baking enamel, and / or on its side facing the bottom film with a sealing layer, wherein the sealing layer is preferably a peelable heat sealing lacquer in one Thickness of about 2 to 8 microns or polyolefin in a thickness of less than 25 microns.

Packaging according to the invention often also serve for the longer storage of a substance and are often at the same time commercial form. A high wear resistance of the packaging is therefore a preferred property of a packaging according to the invention. The provision of corrosion protection has the advantage that, for example, a cover sheet of metallic material is protected from wear by corrosion.

In packaging according to the invention, the cover and bottom films continue to be sealed together at least in sections. To enable this sealing, it is advantageous to arrange (initially) a sealing layer on the side of the cover film with which it is to be sealed to the bottom film. Preferably, the sealant layer is a polyolefin, for example, polyethylene, polypropylene, polybutylene, polystyrene, polycarbonate, a similarly constructed hydrocarbon polymer, or a copolymer of various polyolefins, in a thickness of less than 25 microns. The use of polyolefin in a thickness of more than 25 microns or other plastics, such as PVC, is possible.

The choice of the sealing layer material and the sealing layer thickness is preferably adapted to the configuration of the barrier film of the cover film and to the configuration of the bottom film. The sealing is preferably carried out by welding or gluing the sealing layer of the cover sheet with the bottom foil, preferably with a sealing layer of the bottom foil.

According to a further embodiment of the packaging according to the invention, the first and / or the third portion of the cover sheet each have a central region and an edge region, wherein the deformation resistance of the respective edge region is less than the deformation resistance of the respective central region.

Such an embodiment has advantages in the production, for example, if the deformation resistance of the first and / or third section of the cover film is reinforced by a reinforcement, such as by attaching an adhesive label, and the reinforcement is not provided with the respective entire section of the cover film, but only the respective central area of the first or third section of the cover sheet.

It is preferred in some cases that the edge region of the first and / or third section of the cover film is at least partially not sealed to the bottom film. This has the advantage that a user can grasp the edge region or a section of the edge region in order to remove the cover film or a portion thereof from the bottom film.

In addition, it is preferred that the cover sheet has one, two or more peel-off aids, preferably one, two or more peel tabs.

Such a peel-off aid or peel-ply may facilitate a user's secure gripping of the cover sheet for applying a force required to peel off the cover sheet. Preferably, the peel-off aid or peel-off is arranged on the portion of the cover film, which is to be deducted from the bottom film for opening the removal chamber. Advantageously, one of the edge regions described above, in particular the first section of the cover film, can also serve as a peel-off aid or peel-off.

• eine der Deckfolie zugewandte Siegelschicht, beispielsweise Polyolefin in einer Dicke von etwa 60µm,
• eine Sperrfolie, beispielsweise Aluminiumfolie in einer Dicke von etwa 45µm,
• eine der Deckfolie abgewandte Außenfolie, beispielsweise orientiertes Polyamid in einer Dicke von etwa 25µm,
• wobei vorzugsweise zwischen Siegelschicht und Sperrfolie und/oder Sperrfolie und Außenfolie ein Haftvermittler, beispielsweise ein Kaschierkleber, angeordnet ist, und
• wobei die Siegelschicht, die Sperrfolie und die Außenfolie vorzugsweise in der angegebenen Reihenfolge angeordnet sind.

According to a further embodiment of the invention, the bottom film is formed as a composite film, wherein the composite film preferably comprises:

• a sealing layer facing the cover film, for example polyolefin in a thickness of about 60 μm,
• a barrier foil, for example aluminum foil in a thickness of about 45 μm,
• an outer film facing away from the cover film, for example oriented polyamide in a thickness of about 25 μm,
• wherein preferably between sealing layer and barrier film and / or barrier film and outer film, an adhesion promoter, such as a laminating adhesive, is arranged, and
• wherein the sealing layer, the barrier film and the outer film are preferably arranged in the order given.

As already shown for the cover film, it is also advantageous for the bottom film to provide a sealing layer on its side to be sealed to the cover film. Preferably, the sealant layer is a polyolefin, for example, polyethylene, polypropylene, polybutylene, polystyrene, polycarbonate, a similarly constructed hydrocarbon polymer, or a copolymer of various polyolefins, in a thickness of about 60 microns. The choice of the sealing layer material and the sealing layer thickness is preferably adapted to the configuration of the barrier film of the bottom film and to the design of the cover film, in particular its sealing layer. The sealing is preferably carried out by welding or gluing the sealing layer of the bottom film with the cover film, preferably with the sealing layer of the cover film.

A barrier film is advantageous in order, as already shown, to improve or extend the shelf life of the substance. The outer film has the advantage of giving the package overall stability. An optional adhesion promoter disposed between the layers may promote a composite effect of the layers. The adhesion promoter is preferably solvent-resistant, especially if the substance to be stored makes this necessary.

In a preferred embodiment, the bottom film is formed as a coextruded film, in particular as a coextruded multilayer film. In this case, for example, a polyolefin layer can be applied in a liquid state in a hot state and the adhesion promoter to be applied to the mass to be applied.

The bottom foil of a packaging according to the invention is preferably designed as a thermoforming foil.

Such an embodiment is manufacturing technology and in terms of the cost of packaging advantage.

The removal chamber of a packaging according to the invention is preferably designed as a trough covered by the cover foil in the bottom foil.

Preferably, one or more further chambers are formed as wells covered by the cover film in the bottom film.

Chambers of the package are preferably formed by depressions or wells in the bottom foil. The chambers can be filled according to need and function and are then covered by the cover sheet. By sealing cover sheet and bottom sheet in the areas surrounding the chambers, the chambers are closed before being opened again by peeling off the coversheet or at least a portion of the coversheet and made accessible for use.

Another preferred packaging according to the invention has one, two or more stabilizing beads formed in the bottom film.

The stabilizing beads may be formed as further, unfilled troughs in the bottom foil. They then serve primarily to increase the stability of the package as a whole. Furthermore, it is preferred that the stabilizing beads have a substantially same height as the removal chamber and possibly further troughs of the bottom foil, so that the package can be placed on a substantially flat surface, in particular without substance unintentionally escape from the package or leak can.

In the following, preferred features of the packaging according to the invention with regard to the formation of the seal will be described. This preferred embodiment of the packaging according to the invention is preferably present at the same time as further preferred embodiments of the packaging according to the invention.

In preferred packaging according to the invention, the cover film and the bottom film are sealed together by a seal.

The sealing takes place preferably via the sealing layer of the cover film and / or the sealing layer of the bottom film.

The seal is preferably peelable at least between the first section of the cover film and the bottom film, so that the first section of the cover film is peelable from the bottom film.

If the cover film and the bottom film are connected to each other via a peelable seal, they can be separated by "peeling" (English for "peel off"). This is an advantageous and preferred way to open chambers of the package, in particular the removal chamber, without having to pierce the cover sheet or bottom film and without having to provide an opening with a corresponding closure in one of the films.

The seal is preferably made completely peelable between the cover film and the bottom film, so that the cover film is completely removable from the bottom film.

This embodiment is advantageous, for example, when the removal chamber or several removal chambers extend over a large part of the length of the packaging and should be opened immediately or gradually the entire removal chamber or all removal chambers. The embodiment can also be advantageous if, for example, an applicator is to be stored in the packaging, which can be removed in a user-friendly manner only by completely removing the cover film from the bottom film.

In individual cases, it is advantageous to design the seal between cover film and bottom film in such a way that it has different sealing strengths in some sections.

The seal between the cover film and the bottom film may have different properties depending on, for example, the thickness and material of the sealing layer (s), the manner of producing the seal (eg welding, gluing) or the geometry of the seal. These properties include the seal strength. The sealing properties and the measures for their production are known to the person skilled in the art. In the context of the present invention, it is often preferred that the strength of the seal varies in sections.

It is preferred that the seal between the cover film and the bottom film has regions with different sealing geometries, preferably regions with a surface seal and / or regions with a line-shaped seal.

This formation of the seal can serve, for example, to influence the seal strength as described above or to allow the formation of different chambers.

The seal between the second portion and / or the third portion of the cover sheet and the bottom sheet preferably has a higher strength than the seal between the first portion of the cover sheet and the bottom sheet.

It is particularly preferred if the seal strength between the first portion of the cover film and the bottom film is lower than the seal strength between the second and / or third portion of the cover film and the bottom film. This is advantageous, for example, if the first section of the cover film is to be easily removable in comparison to the second and / or third section of the cover film.

The seal between the cover film and the bottom film is preferably peelable in sections and is not peelable in sections.

This embodiment is advantageous if only a certain portion of the cover sheet to be deducted from the bottom sheet and another section permanently, so both in the storage and in the open use or removal state, should remain closed. In the present invention, it is particularly preferred that (only) the first portion of the cover sheet, in some cases the second portion of the cover sheet, is removable.

The deformation resistance of the first section of the cover film is preferably at least partially greater than the seal strength of the seal between the first section of the cover film and the bottom film.

By means of this configuration, it can be achieved that, at least in sections, a force action of a user to pull off the covering film results in the sealing strength of the seal between the first section of the cover film and the cover Overcome ground sheet and the first portion of the cover sheet is released from the bottom sheet, the first portion of the cover sheet but substantially retains its shape.

In other embodiments, the deformation resistance of the first portion of the cover sheet may also be equal to or less than the seal strength of the seal between the first portion of the cover sheet and the bottom sheet. In this case, a deformation of the first portion of the cover sheet may occur when opening the package. In the opened state, however, the deformation, in particular the plastic deformation, of the first section of the cover film is lower in comparison with the deformation, in particular the plastic deformation, of the second section of the cover film.

The deformation resistance of the second section of the cover film of a preferred packaging according to the invention is preferably at least partially smaller than the seal strength of the seal between the second section of the cover film and the bottom film.

According to this embodiment of the invention, at least a part of the second portion of the cover sheet is sealed to the bottom foil. A certain force of a user to peel off the cover sheet now causes the second portion of the cover sheet deforms, but does not dissolve from the bottom sheet.

Furthermore, it is preferred that the seal between the cover foil and the bottom foil is produced by means of welding or gluing.

Methods for producing a seal between the cover film and the bottom film are known to the person skilled in the art. It is also known to produce a seal with certain properties, such as a certain seal strength. A surprising finding of the present invention, however, is that the combinations of certain sealing properties described in this application with certain combinations of material properties of the cover film and the arrangement of the packaging components, the advantages described above and below can be achieved.

In a preferred packaging according to the invention, the seal between cover film and bottom film is at least partially formed fluid-tight.

As already mentioned, depending on the substance to be stored, it may be advantageous to prevent the substance or components from escaping from the closed package, for example by diffusion. In order to ensure this, it is advantageous to seal the cover film and the bottom film, at least in sections, in a fluid-tight manner to one another in order to prevent or reduce diffusion of the substance or of constituent substances through the seal.

In some cases it is advantageous in the case of a packaging according to the invention that a section of the cover film can be separated from the packaging. Relevant preferred features of a package according to the invention are described below. Also, this preferred embodiment of the packaging according to the invention is-as generally-preferably present at the same time as further preferred embodiments of the packaging according to the invention.

The first section of the cover film and the third section of the cover film of a packaging according to the invention are preferably separable from one another after opening the removal chamber by creating a crack in the second section of the cover film.

When handling the package, it may be advantageous to remove the first portion of the cover sheet from the package. For this purpose, the first section of the cover film can be torn off by a user creating a tear in the second section of the cover film. Once this crack extends across the entire width of the second section, the first and third sections are separated. Preferably, the first portion of the cover sheet is separated along a predetermined breaking point formed in the second portion of the cover sheet, for example in the form of a notch or a crack.

The second portion of the cover sheet then preferably has a crack aid or perforation which facilitates the generation of the tear in the second portion, the tear aid or perforation preferably being formed over the entire width, only over part of the width or only in an edge region of the second portion is.

A crack aid or perforation may, for example, as a predetermined breaking point in the form of an incision, a notch or a series of openings of the cover sheet be designed in the second section. Such a crack aid or perforation is advantageous in order to facilitate the cracking and / or control. The configuration of the crack aid or perforation is preferably adapted to the material properties of the cover film, in particular of the second section of the cover film.

Preferably, edge portions of the second portion of the cover sheet on which the crack aid or perforation is located or on which the crack aid or perforation begins are not sealed to the bottom foil. This has the advantage that a user can grasp the edge portion of the second portion of the cover sheet with the crack aid or perforation well and can apply a force to generate a crack on the second portion of the cover sheet.

Preferably, a boundary between the third portion of the cover sheet and the second portion of the cover sheet is formed as a reference line such that the crack in the second portion of the cover sheet is formed substantially parallel to the boundary between the third portion of the cover sheet and the second portion of the cover sheet.

This is particularly advantageous in order to prevent the crack from forming, as desired, in the second section of the cover film, but undesirably at least partially in the first and / or in the third section of the cover film. In this case, in particular, the reinforcing layer of the first or third section of the cover foil can have a supporting effect in such a way that it prevents crack formation in the first or third section or, in contrast to cracking, makes it difficult in the second section of the cover foil.

The features described below relate to a packaging according to the invention which contains an applicator. This preferred embodiment of the packaging according to the invention is preferably present at the same time as further preferred embodiments of the packaging according to the invention.

A further preferred embodiment of a packaging according to the invention comprises an applicator chamber which is separate from the removal chamber and in which an applicator for application of the substance is detachably mounted, the applicator chamber being formed from areas of the bottom foil and the cover foil which are at least partially peelable.

In the case of packages according to the invention and substances stored therein, it is frequently the case that an applicator is needed to apply the substance. It may be advantageous to provide the applicator with in the package, especially if it is a hygienic applicator for single use. Preferably, such an applicator is then stored in a separate applicator chamber of the package in such a way that it can be removed for application of the substance from the applicator chamber.

The applicator may be formed, for example, as a brush, swab, spatula, brush or spoon.

The applicator chamber is preferably arranged such that the applicator chamber can be opened by pulling off the first section of the cover film so far that the applicator can be removed.

It is particularly preferred that both the removal chamber and the applicator chamber are opened by subtracting the first portion of the cover sheet, so that a further measure to open the respective other chamber can be advantageously eliminated.

Advantageously, the applicator chamber has a widened region for facilitating the removal of the applicator, wherein the applicator chamber is preferably arranged such that the extended region of the applicator chamber is accessible at least in sections by subtracting the first portion of the cover foil, in order to allow removal of the applicator as user-friendly as possible ,

The applicator chamber preferably has a device for releasably locking the applicator in the applicator chamber.

Such a device may, for example, be a region-wise constriction of the applicator chamber into which an applicator section engages with a correspondingly reduced cross-section. Alternatively, for example, the applicator chamber can also provide an extended area in which an applicator section engages with a correspondingly enlarged cross-section.

The applicator preferably has a predetermined bending point with which the shape of the applicator of the application environment, for example an oral cavity, can be adapted.

Hereinafter, further features of preferred packaging according to the invention will be described. Preferably, preferred embodiments of the packaging according to the invention, which relate to different features, are present at the same time.

The substance contained in a packaging according to the invention may consist of one or more components.

A component is to be understood as a constituent of the substance, without specifying the homogeneity of the substance, i. The substance may be formed as a one- or multi-component substance, have different consistencies such as powdery, pasty, flowable or liquid and contain homo- or heterogeneous dissolved, solid or gaseous components.

In preferred individual cases, the substance comprises one, two or more fluorides. In a preferred embodiment, sodium fluoride is used alone or in mixture with other fluorides.

The removal chamber of a package according to the invention often has a volume of (approx.) 0.05 ml to 2 ml. Particularly preferred are packaging with volumes of (approx.) 0.4 ml for use in adults and (approx.) 0.25 ml for use in children.

The packaging according to the invention is usually provided as, preferably hygienic, disposable packaging.

In particular, in dental technology substances are often needed that may be used only for a single patient and are preferably provided hygienically for this application, as well as the application tool required for the application of these substances. For this reason, the provision of the packaging according to the invention as a disposable packaging, which is preferably hygienic, is advantageous since the once in contact with a patient - and even if only indirectly via an application tool - substance for a second Patients should be used. The amount of substance stored in the packaging advantageously corresponds to the amount required for the treatment of a patient.

The removal chamber of a package according to the invention preferably has one, two or more markings for dosing the substance to be removed from the removal chamber.

This allows the user to be able to apply only a portion of the substance - and in a precisely metered amount. This is for example of advantage in the treatment of children, for which only a part of the amount of substance required for adults should be used. In the production, this embodiment has the advantage that no different chamber or package sizes must be realized, but by a corresponding removal mark different removal amounts can be provided with the same packaging with the same amount of substance. Advantageously, appropriate information about an appropriate dosage for the user directly on or on the packaging, for example, on the printed adhesive label of the first and / or third portion of the cover sheet attached.

The markings are preferably formed on the bottom film. Furthermore, the markings are preferably formed on the barrier film or on one side of the sealing layer. In a preferred embodiment of the invention, the markings are applied by imprinting, embossing or laser lettering. The markings are preferably in the form of lines, color areas, text information and / or numbers. Furthermore, the markings are preferably applied in the scattering pressure or accurately printed.

These refinements have the advantage of producing the markings as cheaply as possible from a manufacturing point of view and at the same time ensuring good visibility for the user.

The features described below relate to a preferred variant of a packaging according to the invention. Preferably, this preferred variant is with one or more of the further preferred embodiments of a package according to the invention.

In many cases, a design is advantageous in which the substance is stored in the removal chamber and the removal chamber is arranged such that by removing the first portion of the cover sheet, the removal chamber is at least so far openable that the substance is removable.

In this embodiment of the invention, the substance is in both the storage and unloading conditions (i.e., with the sampling chamber closed and open) in the sampling chamber. By removing the first portion of the cover sheet, the removal chamber is opened and the substance made accessible. Preferably, with an applicator, which is also advantageously stored in the package and this is removed, the substance once or repeatedly or successively picked up from the sampling chamber and applied to the target object, such as a tooth of a patient. In particular, in the repeated picking up of substance from the sampling chamber, the advantage of the invention, that the withdrawn first portion of the cover sheet substantially maintains its shape and he does not spring back by an elastic deformation in the second portion of the cover sheet, noticeable as dirt through the first section the cover sheet adhering substance residues are avoided or reduced. Even if the removal chamber already in the storage condition, i. Also, during transport containing substance, by shaking and handling the package, the substance will come in contact with the coversheet and may adhere to it.

A particularly preferred packaging according to the invention is configured as follows:

A package for storing a flowable, pasty or powdery substance, consisting of or comprising a bottom sheet and a cover sheet, which are at least partially sealed together, and a removal chamber, which is formed from at least partially peelable sealed areas of the bottom sheet and the cover sheet, wherein the removal chamber Removing at least a first portion of the cover sheet from the bottom sheet is opened, characterized in that a second portion of the cover sheet arranged adjacent to the first portion has a lower deformation resistance than the first portion of the cover sheet, so that a required for permanent opening of the extraction chamber deformation Cover film occurs substantially in the second portion of the cover sheet, and the bottom sheet is formed as a thermoforming sheet and the removal chamber as a covered by the cover sheet trough in the bottom sheet is formed and the cover sheet and the bottom sheet are sealed together by a seal and the seal is peelable at least between the first portion of the cover sheet and the bottom sheet, so that the first portion of the cover sheet is removable from the bottom sheet.

This particularly preferred packaging according to the invention is preferably additionally characterized by an applicator chamber which is separate from the removal chamber and in which an applicator for application of the substance is detachably mounted, wherein the applicator chamber is formed from regions of the bottom foil and the cover foil which are at least partially removable from each other.

In addition, this particularly preferred packaging according to the invention is preferably characterized in that the applicator chamber is arranged such that by withdrawing the first portion of the cover sheet, the applicator can be opened so far that the applicator is removable, wherein the substance is stored in the removal chamber and the removal chamber is arranged such that by removing the first portion of the cover sheet, the removal chamber is at least so far openable that the substance is removable.

The features described below relate to a preferred alternative variant of a packaging according to the invention with a storage chamber. Preferably, this preferred alternative variant comprises several of the further preferred features of the packaging according to the invention, as described above.

An alternative packaging according to the invention comprises a storage chamber containing the substance separated from the removal chamber and possibly the applicator chamber, wherein in a region connecting the storage chamber and the removal chamber the bottom foil and the cover foil are connected by a seal such that a pressure is applied from outside on the storage chamber in the connecting area, the seal of soil and cover foil dissolves and creates a passageway between the storage chamber and removal chamber, through which the substance from the storage chamber is wholly or partially transferred into the removal chamber.

A certain pressure exerted on the bearing chamber by the user from the outside preferably leads to the seal selectively loosening in the area connecting the bearing chamber to the removal chamber and creating a passageway, through which then the substance contained in the storage chamber is transferred into the removal chamber. Transferred amount and speed of transfer preferably depend on the strength and duration of the pressure exerted by the user on the outside of the storage chamber pressure. This has the advantage that the user can control transferred amount and speed of the transfer even via the variation of the pressure exerted by him on the bearing chamber pressure.

The substance can be transferred to the closed or opened sampling chamber. The latter procedure has the advantage that the substance does not come into contact with the first section of the cover film, which is already removed when the removal chamber is open, and therefore can not adhere to the withdrawn first section of the cover film.

The dosing marks described above are particularly advantageous in relation to the preferred alternative variant of the packaging according to the invention described here, since they can serve a user to dose the amount of the substance which is transferred from the storage chamber into the removal chamber.

The storage chamber is preferably formed as a trough covered by the cover foil, preferably by the third section of the cover foil, in the bottom foil.

The invention can be further configured by the storage chamber usually having a volume of about 0.1 ml to 3 ml.

The substances used in dental technology are usually required in an amount of about 0.05 ml to 0.2 ml for an application. The packaging preferably has corresponding or correspondingly larger chamber volumes to this quantity. In a preferred embodiment, the chamber volume for substances to be provided in an amount of about 0.05 ml to 0.2 ml is about 0.6 ml.

The storage chamber is preferably compressible by a pressure exerted externally on the storage chamber, preferably for transferring the substance contained in the storage chamber into the removal chamber.

A compression of the bearing chamber by a, preferably by a user, exerted externally on the bearing chamber pressure has the advantage that on this Way the substance can be pressed from the storage chamber into the sampling chamber and the storage chamber can be easily emptied.

The features described below form the above-described preferred alternative variant of a packaging according to the invention with a storage chamber with regard to a pressure marking.

The cover film, preferably the third section of the cover film, preferably has a pressure marking, which marks the bearing chamber, on which a pressure is to be exerted from the outside.

Such a mark has the advantage of directly indicating to a user the location of the package to which pressure is to be applied without the need to turn the package, for example, to locate the well of the storage chamber in the bottom sheet.

Furthermore, it is particularly advantageous if the pressure marking is arranged in a reinforced region of the third section of the cover foil, since such a reinforcement can prevent or complicate damage to the third section of the cover foil, such as may occur when the bearing chamber is pressed in by sharp fingernails , without the overall handling of the cover sheet, in particular the removal of portions of the cover sheet, is difficult.

The features described below form the above-described preferred alternative variant of a packaging according to the invention with a storage chamber with regard to the formation of the seal. Preferably, this training of the preferred alternative variant with single or more of the further preferred developments of the package according to the invention is present at the same time.

The seal between the cover foil and the bottom foil in the region connecting the bearing chamber and the removal chamber is preferably weakened such that the seal in the connecting region is released by exerting a pressure on the bearing chamber from outside and a passageway arises between the bearing chamber and the removal chamber the substance from the storage chamber is wholly or partially transferred to the removal chamber.

The targeted weakening of the seal has the advantage that then only the weakened seal is selectively released by a pressure applied from the outside and other, not weakened seal sections remain intact, so that a defined passageway is formed. By targeted weakening, the position and / or geometry of the passage can be defined.

• Anordnung von Fremdpartikeln, vorzugsweise Peelfolienstanzlingen, in dem geschwächten Siegelbereich,
• vor dem Erzeugen der Siegelung Applizieren einer das Siegeln von Bodenfolie und Deckfolie beeinträchtigenden Substanz auf der Bodenfolie und/oder Deckfolie in dem zu schwächenden Bereich,
• Erzeugung der Siegelung durch Verschweißen von Bodenfolie und Deckfolie, wobei in dem die Lagerkammer und die Entnahmekammer verbindenden Bereich die Schweißtemperatur und/oder der Pressdruck beim Verschweißen und/oder die Schweißzeit anders ist als in benachbarten Bereichen,
• Vorsehen unterschiedlicher Sieglungsgeometrien in (a) dem die Lagerkammer und die Entnahmekammer verbindenden Bereich und (b) benachbarten Bereichen.

Preferably, the seal between cover sheet and bottom foil in the area connecting the storage chamber and the withdrawal chamber is weakened due to one or more of the following measures:

• Arrangement of foreign particles, preferably Peelfolienstanzlingen, in the weakened seal area,
• before producing the seal, applying a substance impairing the sealing of the base film and cover film to the bottom film and / or cover film in the area to be weakened,
• Production of the seal by welding of bottom foil and cover foil, wherein in the region connecting the bearing chamber and the withdrawal chamber the welding temperature and / or the pressure during welding and / or the welding time are different than in adjacent regions,
• Provide different Sieglungsgeometrien in (a) the storage chamber and the removal chamber connecting area and (b) adjacent areas.

This and possibly further measures for targeted weakening of the seal in certain areas can be selected by the skilled person according to the materials to be used and the requirements for the properties of the seal.

The passageway of a corresponding packaging according to the invention has a cross-section widening advantageously to the removal chamber.

This embodiment can be realized for example by a corresponding arrangement of the weakened seal in the region connecting the storage chamber with the removal chamber. Such a cross - sectional extension of the Passage channel helps to prevent or reduce spillage of the substance as the substance exits the passageway.

The features described below form the above-described preferred alternative variant of a packaging according to the invention with a storage chamber with regard to the arrangement and design of the removal chamber. Preferably, this training of the preferred alternative variant with one or more of the other preferred developments of the package according to the invention, which relate to different characteristics, at the same time before.

The removal chamber is preferably arranged so that it can be opened at least to the extent that the first section of the cover film is removed, so that the substance to be transferred from the storage chamber into the removal chamber can be removed.

The transfer of the substance from the storage chamber into the removal chamber can take place, for example, before or after the removal chamber is opened.

Preferably, a corresponding package is designed such that a first portion of the removal chamber is covered by the first portion of the cover sheet and a second portion of the removal chamber is covered by the second portion of the cover sheet, so that when removing the first portion of the cover sheet, only the first portion the removal chamber is opened, wherein the second portion of the removal chamber is preferably that portion of the removal chamber adjacent to the region connecting the removal chamber to the storage chamber.

This embodiment has the advantage that a spraying of the substance can be avoided or reduced during its transfer from the storage chamber into the removal chamber. In particular, spraying upwards, usually in the direction of a user handling the packaging when emerging from the passageway, can thereby be avoided, in that the section of the removal chamber into which the passageway opens opens, even after the removal chamber has been opened by the second section of the cover film remains covered. The under certain circumstances quickly exiting substance is guided at the protruding second portion of the cover sheet so that it selectively reaches the extraction chamber and does not squirt out of this. This effect is the more effective the higher the viscosity of the substance to be transferred.

The features described below form the above-described preferred alternative variant of a packaging according to the invention with a storage chamber with respect to further storage chambers. Preferably, this training of the preferred alternative variant with one or more of the other preferred developments of the package according to the invention, which relate to different characteristics, at the same time before.

A further preferred embodiment of the invention is characterized by a second storage chamber containing a second flowable, pasty or powdery substance, wherein in a second storage chamber and an adjacent chamber, preferably the first storage chamber or the removal chamber, connecting region of the bottom sheet and the cover sheet are connected by a seal that dissolves by exerting a pressure from the outside of the second storage chamber in the connecting region, the seal of the bottom and cover sheet and a passageway between the second storage chamber and the adjacent chamber is formed, through which the substance from the second storage chamber is wholly or partially transferred into the adjacent chamber, so that in the adjacent chamber, a mixture of first and second substance can be produced.

In dental technology, substances are often used which need to be mixed together shortly before use. In particular, in such cases it makes sense to provide two substances in two separate chambers in a package and to bring them in contact with each other just before use.

The seal between the cover film and the bottom film in the area connecting the second storage chamber and the adjacent chamber is then preferably weakened such that by exerting a pressure from the outside on the second storage chamber, the seal dissolves in the connecting region and a passageway between the second storage chamber and the adjacent chamber is formed, through which the substance from the second storage chamber is wholly or partially convertible into the adjacent chamber.

For example, the second substance can be transferred from the second storage chamber into the first storage chamber and mixed there with the first substance before the mixture of first and second substance is transferred from the first storage chamber into the removal chamber. However, the first and second substances can also each transferred via separate passageways from the first and second storage chamber into the removal chamber and mixed only in the removal chamber.

It is also preferred that the seal between cover sheet and bottom foil in the area connecting the second storage chamber and the adjacent chamber is weakened due to one or more of the measures already described above.

A further preferred embodiment of the packaging according to the invention is characterized by at least one further storage chamber containing at least one further flowable, pasty or powdery substance, wherein in at least one of the further / n storage chamber (s) and one or more adjacent chamber (s), preferably the first or second storage chamber or the removal chamber, the connecting region of the bottom sheet and the cover sheet are connected by a seal, that by exerting a pressure from the outside of the further / n storage chamber / n in the at least one connecting region sealing the bottom and cover sheet dissolves and a passageway between the further storage chamber (s) and the adjacent chamber (s) is formed, through which the substance (s) from the other storage chamber (s) can be wholly or partly transferred to the adjacent chamber (s), so that a mixture of several substances can be produced in the adjacent chamber (s).

Of course, the packaging according to the invention not only a first and possibly a second storage chamber, but also a third and possibly further storage chambers having a third or optionally further substances. The choice of the number and arrangement of the storage chambers is preferably carried out depending on the substances to be applied and their properties and the desired sequence when mixing the substances.

The present invention also relates to a collecting container for storing at least one flowable, pasty or powdery substance, which is characterized by a plurality of the above-described inventive packaging, which are connected to each other, preferably separable.

Such a collecting container according to the invention is particularly advantageous for transporting and handling the packaging according to the invention, since a single packaging according to the invention often, as described above, a substance only in one for the application in a single patient required and thus usually contains very small amount. The combination of several packaging according to the invention to form a collection container according to the invention simplifies their transport, trading and delivery. Before being used, the packages can advantageously be separated again.

The second section 132 is the shortest of the three sections 131, 132, 133 with the length L _132. The first section 131 is longer than the second section 132 with its length L ₁₃₁ , but shorter than the third section 133 with its length L ₁₃₃ ,

The cover sheet 130 is an aluminum foil having a thickness of 20 μm. On her in Fig. 1 facing upward side, the aluminum foil is provided with a baking enamel, which serves as corrosion protection. On its underside (in Fig. 1 not visible), the cover sheet is provided with a sealing layer of peelable heat sealing lacquer of about 2 to 8 microns. Optionally, the sealant layer can also be made of a polyolefin, for example, polyethylene, polypropylene, polybutylene, polystyrene, polycarbonate, a similarly constructed hydrocarbon polymer, or a copolymer of various polyolefins, in a thickness of less than 25 microns.

The sealing layer of the first portion 131 of the cover sheet is bonded to a corresponding portion of a sealing layer of a bottom sheet (in FIG Fig. 1 not shown) connected by a peelable seal, ie a peelable seal.

Both the first portion 131 of the cover sheet and the third portion 133 of the cover sheet each have a central portion 131a, 133a, which is reinforced by a respective label 131a, 133a. The labels can be designed as adhesive labels made of plastic or paper. In the in Fig. 1 As shown in the embodiment of the packaging, the adhesive label 133a of the third section 133 of the cover film is printed, and the adhesive label 131a of the first section 131 of the cover film is unprinted. Both labels 131a, 133a are on the in Fig. 1 upwardly facing side of the cover sheet, ie on the baking finish of the cover sheet, arranged.

The second portion 132 of the cover sheet has two perforations 132a. The perforations 132 a do not extend over the entire width B _{100 of} the second section 132 of the cover film 130, but are arranged only in outer edge regions of the second section 132 of the cover film 130. Here, the first portion 131 of the cover film 130 is only in its central region 131a to the bottom film (in Fig. 1 not shown) sealed. The edge region 131b of the first section 131 of the cover film 130 lies on the bottom film (in FIG Fig. 1 not shown) and is not sealed to this.

The following describes how the in the Fig. 1 to 6 illustrated first embodiment of the package 100 according to the invention is to handle. In the storage condition, the package 100 is as in Fig. 1 shown closed. In order to be able to remove and apply the substance stored in the packaging, the removal chamber 140 can be opened. This is done in the first embodiment of the packaging 100 shown here, in that a user grips the edge region 131b of the first section 131 of the cover film 130 which is not sealed to the bottom film 120 and has a lower resistance to deformation than the central region 131a of the cover film. This edge region 131b acts as a peel aid or peel-off in this example. When a user has grasped this edge region 131 b, he pulls the first portion 131 of the cover film 130 from the bottom film 120. When peeled off, the first portion 131 of the cover sheet may deform (for example, roll up), but preferably at least a part, preferably a substantial part, elastically deforms after deformation of the first portion 131 of the cover sheet. A substantial portion of the plastic deformation of the cover sheet 130 required for opening occurs along the fold line formed in the second section 132 between the perforations 132a. The resulting deformation in the second section 132 of the cover film is an at least substantially plastic deformation, ie that the deformation in the second section 132 at most recovers slightly elastically.

The opened package 100 is in Fig. 2 shown. The representation of the first portion 131 of the cover sheet in Fig. 2 is schematic, in actual use of a Packaging according to the invention is to be expected with a partially plastic deformation of the first portion 131 of the cover sheet in the open state. It can be seen that after removal of the first section 131 of the cover film from the bottom film 120, the removal chamber 140 with the dental material 110 is accessible and furthermore the extended region 160a of the applicator chamber 160 is exposed.

The user can now grip the applicator 170 and remove it from the package. The extended portion 160a of the applicator chamber 160 facilitates the grasping of the applicator 170 for the user. The applicator now allows the user to apply the dental material 110 to a target object, such as a patient's tooth. In this case, the packaging 100 can optionally be placed on a substantially flat surface, for example a tray, or the packaging 100 can be held in the user's hand during application. Among other things, in that the deformation occurring in the second portion 132 is substantially plastic, and the first portion 131 of the cover sheet is less plastically deformed, the handling of the package is where the underside of the first portion 131 of the sealing film is adhered to the dental material 110 can be improved.

Optionally, the seal between the second portion 132 of the cover sheet and the bottom sheet 120 and optionally also between the third portion 133 of the cover sheet and the bottom sheet 120 may be formed such that the cover sheet 130 can be completely pulled off the bottom sheet 120 and removed.

Advantageously, however, the cover film 130 remains at least partially in contact with the bottom film 120, so that the user can complete the packaging 100 in one piece and thus in a single operation after completing the application of the dental material 110.

The Fig. 7 to 11 show a second embodiment of a package 200 according to the invention. The second embodiment of the package 200 is similar in many design details to those of the first embodiment of the package 100. In the following, therefore, especially the essential differences of the second embodiment of the package 200 are shown in detail. For the other, with the first embodiment substantially identical design details and - variants will be to the description of the Fig. 1 to 6 directed.

The second embodiment of the packaging 200 according to the invention has a cover film 230 with a first section 231, a second section 232 and a third section 233. The first and the third section of the cover film 231, 233 each have an adhesive label in their central regions 231a, 233a. The structure of the cover sheet 230 corresponds to the structure of the cover sheet 130 of the first embodiment of the invention as described in the description of FIGS Fig. 1 to 6 explained. The second portion 232 of the cover sheet has perforations 232a.

As in 8 to 11 to recognize, the package 200 also has a bottom foil 220, which according to the reference to the Fig. 1 to 6 described bottom foil 120 of the package 100 is constructed. The bottom foil 220 has a removal chamber 240, a storage chamber 290, an applicator chamber 260 with an extended region 160a, and two stabilization beads 250. In the applicator 260 an applicator 270 is detachably mounted.

The cover sheet 230 and the bottom sheet 220 are sealed together by their sealing layers so that at least the first portion 231 of the cover sheet can be peeled from the bottom sheet, i. the first portion 231 of the cover sheet is peelably sealed to the bottom sheet 220.

Fig. 7 shows the second embodiment of the package 200 according to the invention in a three-dimensional view. In the third section 233 of the cover film 230 is located on the label 233a a print mark 233c. This pressure mark 233c is also in the Fig. 8 . 9 and 11 to recognize. It is located above a storage chamber 290, which in the FIGS. 9 and 10 can be seen. In the in the Fig. 7 to 11 illustrated second embodiment of the package 200 is the substance in contrast to those in the Fig. 1 to 6 shown first embodiment of the package 100 is not stored in the sampling chamber but in the storage chamber 290. The substance itself is in the Fig. 7 to 11 not shown. As in Fig. 10 1, the second embodiment of the packaging 200 also has stabilizing beads 250 which, however, are shorter than the stabilizing beads 150 of the first embodiment of the packaging 100.

In a region 290a connecting the removal chamber 240 to the storage chamber 290, the seal between cover film 230 and bottom film 220 is weakened.

• Anordnung von Fremdpartikeln, vorzugsweise Peelfolienstanzlingen, in dem geschwächten Siegelbereich,
• vor dem Erzeugen der Siegelung Applizieren einer das Siegeln von Bodenfolie und Deckfolie beeinträchtigenden Substanz auf der Bodenfolie und/oder Deckfolie in dem zu schwächenden Bereich,
• Erzeugung der Siegelung durch Verschweißen von Bodenfolie und Deckfolie, wobei in dem die Lagerkammer und die Entnahmekammer verbindenden Bereich die Schweißtemperatur und/oder der Pressdruck beim Verschweißen und/oder die Schweißzeit anders ist als in benachbarten Bereichen,
• Vorsehen unterschiedlicher Sieglungsgeometrien in (a) dem die Lagerkammer und die Entnahmekammer verbindenden Bereich und (b) benachbarten Bereichen.

The weakening in the connecting region 290a may be caused by one of the following measures:

• Arrangement of foreign particles, preferably Peelfolienstanzlingen, in the weakened seal area,
• before producing the seal, applying a substance impairing the sealing of the base film and cover film to the bottom film and / or cover film in the area to be weakened,
• Production of the seal by welding of bottom foil and cover foil, wherein in the region connecting the bearing chamber and the withdrawal chamber the welding temperature and / or the pressure during welding and / or the welding time are different than in adjacent regions,
• Provide different Sieglungsgeometrien in (a) the storage chamber and the removal chamber connecting area and (b) adjacent areas.

The removal chamber 240 has markings 280 which serve for metering the substance to be transferred from the storage chamber 290 into the removal chamber 240. The markers 280 have dashes provided with numerals indicating what amount of substance is contained in a filling of the extraction chamber 240 up to the respective stroke of the mark 280. Additionally or alternatively, the markers 280 may also contain colored markings and / or text. Furthermore, the markings may be printed or embossed. In the in the Fig. 8 and 11 In the embodiment shown, the marking is applied over the entire width B _{200 of} the packaging. However, it is also possible to apply the marking only in the region of the removal chamber 240 or only part of the removal chamber 240. In principle, the marking 280 can be configured as desired, as long as it makes it possible to dose the substance to be transferred from the storage chamber 290 into the removal chamber 240 in its quantity.

The handling of the second embodiment of the packaging 200 according to the invention takes place as described below. In the edge region 231b of the first portion 231 of the cover sheet 230, which is not located on the bottom sheet 220, engages a user the cover sheet 230 and pulls the first portion of the cover sheet 231 from the bottom sheet 220 from. In this case, a plastic deformation occurs in the region 232 of the cover foil 230. With the aid of the perforation 232a, the user creates a tear 232b through the second portion 232 of the cover sheet. Thereby, the first portion 231 of the cover sheet is separated and can be disposed of.

The removal chamber 240 is arranged such that only a first portion 240a of the removal chamber 240 is exposed by the removal of the first portion 231 of the cover sheet. A second portion 240b of the extraction chamber 240 remains below the second portion 232 of the cover sheet.

By removing the first portion 231 of the cover film, the extended area 260a of the applicator chamber 260 is also exposed, so that the user can easily remove the applicator 270.

In a further step, the user exerts external pressure on the removal chamber 290. In this case, the user preferably uses thumb and forefinger to exert pressure on the cover film from above on the printing chamber 233c arranged above the bearing chamber 290 and from the bottom onto the bearing chamber 290 with thumb and forefinger. As a result of this pressure exerted on the bearing chamber 290 from the outside, the seal dissolves in the connecting region 290a, so that a passageway between the bearing chamber 290 and the removal chamber 240 is formed and the substance can be transferred from the storage chamber 290 into the removal chamber 240. The label 233a of the third section 233 of the cover film advantageously reduces the risk of damage to the cover film 230, for example due to sharp fingernails when the bearing chamber is pressed in.

The amount of the transferred substance depends on the pressure exerted on the storage chamber 290 pressure. The user can therefore control the amount and speed of the substance to be transferred to the extraction chamber 240 by varying its pressure on the storage chamber 290. In this case, it proves to be advantageous that the second section 240b, which adjoins the connecting region 290a and the passage channel formed between the extraction chamber and the bearing chamber, continues to be covered by the second section 232b of the cover film, since in this way a splashing occurs the substance can be prevented. Using the markers 280, the user can see how much substance he is from the Storage chamber 290 has transferred into the removal chamber 240. If only a certain amount of substance is needed (for example, in the treatment of children), the transfer of substance from the storage chamber 290 into the withdrawal chamber 240 may be stopped by the user ceasing to apply pressure to the storage chamber 290. The desired amount of the substance to be administered, which is now located in the removal chamber 240, can be used below. For this purpose, the applicator 270, here a brush, likewise mounted in the packaging 200, is preferably used for this purpose. After applying the desired and required amount of substance, the package 200 may be discarded.
