Description
CHILD-RESISTANT PACKAGING
The invention relates to a child-resistant packaging, in particular a médicinal product packaging, comprising at least one blister card, wherein the blister card comprises two films, of which one film is configured as a carrier film with at least one blister cavity for receiving packing product, in particular for receiving a pharmaceutical active substance formulation such as a tabiet and forms a top side of the blister card, and the other film is configured as a push-through cover film, wherein the cover film at least in sections is connected extensively to the carrier film îeaving open the at least one blister cavity, and at least in sections fomns an underside of the blister card opposite the top side and the cover film closes the at least one blister cavity filled with packing product.
Many varied embodiments of packagings which are considered to be chiîd-résistant and/or senior-friendly are already known from the prior art,
According to DIN EN 14375 in the current version of September 2016, in Europe nonreclosable packagings for pharmaceutical products are considered to be “child-résistant if at least 85% of a test group of infants aged from 42 to 51 months are not able to gain access to more than eight of at least ten presented dose units, Le. for example, tablets, capsules or dragées within ten minutes. The packing is considered to be senior-friendly if at least 90% of a test group of adults gains access to at least one of the dose units in the one-minute test.
The relevant provisions in the USA, which are specified there in the “Poisons Prévention Packaging Act” (PPPA) are however comparatively substantially stricter. There children must not create any access to a dose which can cause serious damage in a “childresistant” packaging. In extreme cases, this can already be possible by removing only one tabiet or one dose unit.
For example, DE 20 2004 003 781 U1 discloses a child-resistant rectangular packaging comprising two interconnected films, wherein an extensive closure area encloses a receiving space for filling material. For opening and removing the filling material, for example, a tabiet, the receiving space is opened along a marked weakening line or by removing an edge portion of the films.
Likewise DE 10 2004 062 864 A1 discloses a film container with two interconnected films as welî as with receiving chambers for a fiiling material, wherein at toast one of the films is provided with markings for tearing open the films. The marking is exposed after a bending of the films whereupon the filling material can be removed from the film container by tearing open the films.
A disadvantage of these known designs of tear-open packagings is at least that the manufacture of films with tear-open sections which are usualiy designed as métal films is expensive. Furthemnore, with such tear-open packagings it cannot be eliminated that infants can also remove several dose units at the same time which is why such tear-open packagings are not considered to be “child-resistant at least in the USA.
In addition so-called wallet packagings are already known from the prior art. Thus, for example, the documents DE 20 2006 007 553 U1. DE 44 29 503 C2 and EP 2 055 649 A1 discîose packagings in which blister packs as btister strîps or b lister cards serve as primary packaging for the packing material and these are interconnected with a secondary packaging, for example, made of folded card. For child-proof protection, for example, tableis as packing material are in this case therefore located in a manner known per se in cavities of a btister strip or a blister card heat-sealed inside a folded box or a folded carton. For this purpose the blister cards can, for example, be adhesively bonded, sealed, riveted or fïxed with labels onto the outer secondary packaging or altematively inserted removably in cartons of the secondary packaging. For child proofing, depending on the design, the outer secondary packagings, mostly in the form of folded boxes, are designed so that access to the internai blister cards is made difficult.
The document GB 2 352 231 A also discîoses a wallet packaging in which the entire blister card filled with tablets can be removed from the secondary packaging. For this purpose the blister card is removed from a latéral slot of the secondary packaging.
Even with such wallet packagings it is not excluded that infants can also remove several dose units from the internai blister cards after opening the outer folded box packaging. In addition, the manufacture of such multilayer packagings with different packaging materials is expensive.
Blister packs for médicinal products such as tablets, capsules and dragées hâve been known for a long time and must be visually attractive and application-safe. The term blister pack is usualiy understood as a visible packaging, i.e. a product packaging which allows the customer or purchaser to see the packed goods.
Blister packs are widely used for the packaging of pharmaceutical active substance formulations such as, for example, tablets. Such packagings are also called push-through pack and are usualiy produced in strip- or card form. A blister card or a blister strip usualiy comprises two films, of which one carrier film is usualiy made of transparent plastic. Individual indentations, so-called blister cavities are formed in the carrier film into which the packing product, mostly individual dose units of tablets, capsules or dragées are inserted and which are seaied with a cover film, for exampîe, made of aluminium. For example, deep-drawn plastic trays with an aluminium cover film sealed on the back are used for packaging tablets,
Such blister packs offer several advantages over glsss or plastic bottles. They are more hygienic, depending on the film materials used, undesirable influences such as high air humidity or dirt can be eiiminated with such blister packs and it rs also easier to îdentify the remaining number of dose units in the packaging. Spécial blisters also allow the dose schedule to be depicted on the packaging. For example, the packaging of many contraceptive pills is printed with days of the week. By this means it is not oniy possible to monitor what has been taken but different tablets can also be reliably assigned to the days of the menstruai cycle.
In addition to the primary task of packaging, blister packs which are “child-résistant must also be designed to be senior-friendly however, wherein the requirements of these two groups of users are contrary to one another. This is because child-résistant packagings for protecting infants on the other hand présent an insurmountable obstacle for seniors.
For exampie, so-called “peel-push blisters are used in which blister packs are additionally provided with removable (peelable) safety films in a “child-résistant” manner In this case, firstly the removable films must be removed from the cover films as pushthrough protection before the corresponding dose can be pushed from the packaging through the cover film, However it is frequently difficult for older people to be able to grip and remove such removable safety films,
Furthermore, in hitherto known blister packs it is frequently a disadvantage that blind people cannot dîstinguish by means of the blister card which médicament is invoived. However, this probiem not only arises for blind orvisualiy impaired people. In most cases, on a blister card the product and company name of the médicinal product is printed on the sealing layer, i.e. on the cover film which is usually an aluminium film. As soon as several dose units hâve been removed from the blister card by pushing through the cover film, in most cases the imprint with the name of the médicinal product can no longer be identified or only identified with difficulty, with the resuit that the risk of undesired confusions is increased.
A further disadvantage of conventional blister packs is that the dose units are usually pushed out from the blister pack by pushing through into the hand of the patient or onto a base such as, for exampie, a table top. in this case nowever, one or more dose units removed, for example, tablets, can undesirably fall to the floor which is particularly problematical for older persons, ]n addition, removal by hand is mcstly not possible in a hygienic manner. This is particularly the case for persons who hâve to take tablets at spécifie time intervals even during their work time and cannot wash their hands for this in each case. As an example, mention is made here of building workers or craftsmen who must possibly remove and grasp tablets from a conventional médicinal product packaging with contaminated hands.
It is therefore the object of the présent invention to provide child-resistant packaging, in particular a child-resistant médicinal product packaging which at the same time is also senior-friendly and avoids the described disadvantages of the prior art.
This object is achieved in a child-resistant packaging according to the preamble of Claim 1 with the features of the characterizing part of Claim 1. The dépendent claims relate to further advantageous embodiments ofthe invention.
!n a child-resistant packaging according to the invention, in particular in a médicinal product packaging according to the invention, comprising at least one blister card, wherein the blister card comprises two films, of which one fiim is configured as a carrier film with at least one blister cavity for receiving packing product, in particular for receiving a pharmaceutical active substance formulation such as a tablet and forms a top side of the blister card, and the other film is configured as a push-fhrough cover film, wherein the cover film ai least in sections is connected extensively to the carrier film leaving open the at least one blister cavity, and at least in sections forms an underside of the blister card opposite the top side and the cover film closes the at least one blister cavity filled with packing product, at least one backing card is fastened in a movable manner at two opposite side edges or at two opposite peripheral portions of the blister card and this backing card in a securing position is configured to rest at least in sections in a planar manner on the underside of the blister card and in so doing to secure the enclosed packing product against unintenîionaî removaî and against pushing through of the cover film, wherein the backing card can be transferred reversibiy from the securing position into a removal position by means of an extemal force application by mirror-inverted compression of two mutually opposite and spaced apart packaging portions, wherein du ring the removal position fixed by external application of force, the ai least one backing card is spaced apart from the underside of the blister card forming a packaging interior having at least one packing product removal opening wherein in the removal position the packing product can be released by pushing through the cover film into the packaging interior and removed from the packaging interior through the at least one packing product removal opening.
The carrier film of the blister card has one or more fold edges and/or perforations as weakening line s in order to be able to be folded, folded or curved along the se defined edges or weakening fines. It is thereby ensured that largely independently of the choice of material of the packaging, the movement transition between the securing position in which no external application of force is made to the spaced apart packaging portions and the removal position fixed during an external application of force is a réversible toand'fro movement Depending on the arrangement, one or more fold edges in the carrier film of the blister card can also ensure that the packaging has a sufficient stability or buckling résistance as a resuit of the foid edges.
It is advantageous with such a packaging that for children, access to the packing product, in particular to a packed pharmaceuticaî active substance formulation, is blocked since the packaging is designed so that infants cannot embrace with one hand the mutuaüy opposite packaging portions which must be compressed in a mirror-inverted manner with one hand to transfer the packaging from the securing position into the removal position. To this end, the two mutually opposite packaging portions which must be compressed are advantageously to far from one another for an infant to be able to accomplish this with one hand. The packaging is designed so that it is only sufficiently stiff in the removal position fixed by mirror-symmetric compression during the application of an external force so that in this removal position the packing product or a tablet can be removed from a blister cavity by pushing through the cover film of the blister card, Thus, in any case a simuitaneous two-handed actuation of the packaging is required. The packaging must be brought into the removal position by compression and fixed therein in order that at the same time, one or more packing product units can be pushed through into the packaging interior from the corresponding blister cavities with the other free hand.
Therefore two hand grips must be executed simultaneously which is aimost impossible for infants in the test âge from 42 to 51 months specified according to DIN EN 14375 as a result of their motor capabilities and the size of their child hands. By suitably selecting the distances between the pressure points on the opposite packaging portions which must be compressed with one hand for réversible fixing of the removal position in order to be able to push through the packing product from the blister card simultaneously with the second hand, depending on the individual requirement, certain âge groups of infants can be reliably deterred from any possible access to the packaging content or to the packing product. In the design of the packaging according to the invention, care must therefore be taken to ensure that the distances between frie pressure points on the opposing packaging portions în order to compress these are sufficiently far from one another so that children’s hands cannot compress these with one hand.
Particularly flexibly by means of a suitable choice of these dimensions, i.e. the distances between the pressure points on the opposite packaging portions of the packaging according to the invention and by means of a suitable sélection of blister cover films known per se by means of which the push-through force for pushing through or for removal of the packing product can be varied, the packaging according to the invention can also be adapted particularly flexibîy to safety conditions valid in each case. Thus, for example, it is possible for a chiid-resistant packaging to design the packaging according to the invention according to the current requirements of the PPPA in the USA so that 5 infants cannot open this packaging using only their hands v.ithout the assistance of external tool. At the same time however, in tests with prototypes of the packaging according to the invention it has been shown that seniors in care homes as subjects had no problems with gripping the packaging with one hand and compressing it so that this was fixed in its removal position and the seniors could remove individual tablets from the 10 blister cards of the packaging in a manner known per se using the other hand.
Subsequentiy the teim a blister card selected here should also be understood as synonymous with the likewise usual désignation of a blister strip as blister pack for individual packing product units such as, for example, tablets.
Depending on the choice of material and layer structure of the blister cover films, it is 15 possible for example to vary the pu sh-through force for pushing through or for removing the packing product in a range between about 20 N and 120 N. These push-through forces were determined in tests with a so-called pharma pin having a diameter of 10.5 mm. Depending on the product to be packaged or depending on the potentia! hazard of the pharmaceutical active substances in the packing product, at least two parameters are 20 thus availabîe for the particularly flexible and individual design of a safety-confirming packaging according to the invention.
Ail the materials known from the prior art can be used as blister films. The carrier film and the cover film can be constructed of one or of several layers. The cover film is connected to the carrier film, for example, by adhesive bonding, heat-sealing or sealîng. For 25 example, plastics such as polyamide (PA), polyester (UP), poiycarbonate (PC), poiypropylene (PP), poîyethylene (PE), polyvinyîchloride (PVC) or corresponding copolymers can be used as typical materials for the carrier film. For example, composite materials such as one or more plastic films with paper or cardboard layers can be used as carrier film. For example, métal films such as aluminium films or aluminium composite 30 films produced from aluminium and a plastic, for example, can be used as cover film.
Likewise composite films vapour-coated with aluminium or laminated paper films can be used as cover films.
The at least one backing card which rests on the underside of the at least one or the plurality of blister cards filled with packing product as child-résistant removal protection in 35 the securing position of the packaging can optionally be constructed of one or several layers, Expediently the backing card can be constructed ofthe same materials from which the at least one blister card is produced. It is also possible within the scope of the invention that the backing card is made from a different material than the materïals used to construct the blister cards
In a simple embodiment, a single-iayer or sîngle-pîy reinforcement layer for example made of a transparent plastic with appropriais stiffness can be used as backing card. Within the scope of the invention, the backing card can also be configured as a multilayer reinforcing plate.
in a further preferred embodiment the backing card can aiso be a further blister card which is arranged in a mirror-inverted manner with respect to the first blister card and is fastened movably to the biister card and in which the push-through cover films are in each case oriented facing one another towards an interior packaging interior. Thus, robust carrier films which protect the packing product towards the outside are arranged on the outside of the packaging on the outer surfaces thereof.
Within the scope of the invention, depending on the design of the packaging the concept of a backing card should thus be understood as an extensive reinforcement layer or reinforcement plate approximateiy the same size as one or more blister cards which can hâve a single-ply or multiply structure. A backing card can, for example, be formed from a carrier film which is also provided with the blister card or can optionally also be a blister card with the corresponding biister cavities for receîving packing product.
The backing card serves as a backing means or as protective means for protecting the cover film of the biister card and should prevent the cover film of the blister card being pushed through or damaged in the securing position of the packaging. The backing card thus acts as a cover card for covering or for protection for the opposite cover film on the underside of the associated blister card. in contrast to the previously mentioned known remcvable (peelable) security films which are adhesiveiy bonded for protection of cover films directly to these and which must be removed from these cover films again, the backing card however forms its own portion of the packaging separate from the cover film of the opposite blister card associated therewith to be protected. !n the securing position for protection offrie cover film arranged opposite the backing card certainîy rests on this but does not adhéré to this. The backing card can be moved, shifted, pivoted, folded and/or swiveîled into a position spaced apart from the cover film by appropriate compression in the removal position of the packaging, depending on the design of the packaging. Advantageously no pulling or release of the backing card from the cover film is required for this. The interior packaging space which is enclosed by the one or the plurality of blister cards as well as by one or by a plurality of backing cards affords the advantage that packing product such as a tablet, for exampie, which in the fixed removal position was pushed out of the corresponding blister cavity by pushing through the cover fiim initially enters into the packaging interîor of the packaging and can be removed from the packaging interîor through a removal opening.
It is thus advantageously avoided that a tablet must be pressed from a conventional blister pack onto an external base such as a table and can be lost in so doing. Furthermore, by appropriate design of the packing product removal opening, this can be configured to that, for example, a tablet can be poured directly from the packaging interîor into the mouth of the patient without this needing to be grasped by hand for this purpose.
According to the invention, the backing card can be reversibiy transferred from the securing position into a removal position by means of application of an external force by mirror-inverted compression of iwo mutuaily opposite and spaced apart packaging portions. By this it should be understood that the packaging is designed so that at least one backing card by îtself afone or however in combination with at least one 15 corresponding blister card or with further backing cards can be transferred from the securing position into the removal position by compression by means of one hand of the user who would like to open the packaging. This movement should be understood as réversible as a to-and-fro movement between the securing position - without external application of force on the spaced-apart packaging portions - and the removal position, - during the application of external force on the spaced-apart packaging portions. The corresponding two mutuaily opposite and spaced-apart packaging portions can be marked in colour for exampie according to the design and application of the packaging and/or can hâve a structural or haptic design such as, for exampie, an embossing, fluting or pimpling.
Depending on the embodiment and design of the packaging, it can be necessary that after pushing through a dose unit of the packing product into the packaging interîor, wherein the packaging is fixed in its removal position by compressing, the packaging must then be gripped again to empty the packaging interîor. This can be the case, for example, when side tabs on the narrow sides must be compressed to transfer the packaging from its securing position into its removal position. Foremptying the packaging interîor, it can however then be provided that on a narrow side the side tabs must be opened which can make it necessary to grip the packaging again. This further additional handling step can further improve the manipulation security of the packaging against unintentional actuation by infants.
As a resuit of the movable fastening of the at least one backing card on two opposite side edges or on two opposite perîpheral portions of the blister card, these packaging portions are movably coupled to one another.
The packaging according to the invention is in no way limited to the accommodation of 5 packing product with pharmaceutical active substances, i.e. to médicinal product packaging. Likewise arbitrary units of packing product can be stored in a packaging according to the invention, which, for example, are so small that as a resuit of their size they are hazardous for infants and can be swailowed by infants. Merely as an example for this, in addition to food supplément préparations, chewing gums or chewing dragées Ί0 such as nicotine chewing gums, mention is made of smaii electronic components, replacement parts, tool inserts, disposabie metering instruments, disposable needles and the like which can also be stored securely in packagings according to the invention. Thus, it can be advantageous if, for example, replacement parts for E cigarettes or for LED lights which are very small and can be swailowed by infants, are stored in a packaging 15 according to the invention in a child-resistant manner.
Subsequentiy in the description the assignment of spécifie terms with regard to a location, a position or an orientation such as, for example, “horizontal”, ‘'vertical”, “in the horizontal direction, “in the vertical direction, “above”, “below”, “inside”, “outside”, “front”, “thereunder, “thereover” etc. is merely selected for simplification and these details 20 possibly relate to the représentation in the drawings but not necessarily to a usage or storage position of the packaging according to the invention. In order to cîarify that in the intended use of the packagings according to the invention, the cover films of the blister cards to be protected are each oriented inwards towards the packaging interior, the undersides of the blister cards covered with the cover films at least in sections each 25 correspond to the inner sides of the blister cards in relation to the packaging interior of the packaging.
It can be particularly expédient if in a packaging according to the invention, the at least one backing card comprises a carrier film or is formed from a carrier film.
As already mentioned previously, the backing card serves in each case as mechanical 30 protection of the blister card in order to proteci the packing product or the tablets from unintentional removal as a resuit of pushing through the cover film. For this purpose, in a rlid lÎaHw onrl Λ-ί Ihù irMjûnhnn lûCüf λπο pcil ULAJiCiÎ iy en worum wu vo x ri t ivi il ui tilt ii i yüi »iivi x m ιναοι WI Md^rxu iy card made of a carrier film or comprising a carrier film can be fastened movably to the blister card. In a securing position this backing card comprising a carrier film is configured 35 to rest in a planar manner on the underside of the blister card at least in sections and thereby secure the enclosed packing product against an unintentional removal and against pushing through the cover film.
Particularly advantageously in a packaging according to the invention, the at least one blister card as well as the at least one backing card can each be configured in the form of rectangles, wherein the backing card is fastened in each case on two opposite side edges or on two opposite peripheral portions of the long sides of the blister card.
In this variant of the invention the blister cavities for receiving packing product units can be arranged accordingîy in rows or in matrix fashion according to the size of the rectangular blister card. The at least one backing card is expedientiy also configured in rectangular form and has substantialiy the same dimensions as the corresponding blister card the protection of which the backing card is provided. The two cards are fastened movably against one another along their opposite long sides. Depending on the embodiment, the two cards can be fastened to one another directly on their long side edges or along peripheral portions along their long side edges. Removal of packing product already pushed out from the blister cavities from the packaging interior between the blister card and the corresponding backing card is accomplished in the removal position of the packaging at its narrow sides.
In an advantageous further development of the invention, in a packaging the at least one backing card can be movably fastened by means of connecting tabs, preferably by means of a plurality of serially arranged connecting webs at two opposite peripheral portions of the blister card.
In this embodiment the packaging interior is delimited laterally by the movable connecting tabs or connecting webs. These connecting tabs or connecting webs are arranged so that they allow a réversible translation movement or relative movement in the longitudinal direction of the blister card and the corresponding backing card between the securing position and the removal position of the packaging.
Particularly advantageous in a packaging according to the invention at least one inscription tab can be fastened to the blister card and/or the backing card.
As a resuit of the at least one inscription tab on the packaging, the imprint, for example, the product and/or company name of the packing product or the médicinal product is clearly îegible at any time. The inscription can, for example, also be accomplished in Braille script so that biind peopie or visually impaired peopie can directly identify on the packaging and independently of the degree of dose units or packing product units already removed which packed product or médicament it is. The inscription tab can be attached on one side or both sides of the packaging.
For example, details of the removal intervals of the packed dose units can be printed directly on one or more inscription tabs which are connected directly to the blister card and/or backing card.
It is also provided within the scope of the invention that one or more inscription tabs are provided to be printable or embossable in order to be able to design the packaging with individual information on removal intervais.
it can be advantageous if in a packaging according to the invention, the at least one inscription tab is fastened at a side edge or at a perîpheral portion of the blister card and projects over the blister card.
In one embodiment the one or the plurality of inscription tabs is/are not only particularly easy to read but they can also be designed so that as a resuit of these inscription tabs the compression of the packaging, i.e. the transfer from the securing position into the removal position of the packaging is made difficult for chi!d hands. This can be achieved, for example, by roughened and/or jagged portions on the outer edges of the inscription tabs which are unpleasant for infants to grasp with small children’s hands and which consequently prevent compression preciseiy at these packaging portions.
A packaging according to the invention can be designed to be particularly applicationsafe if the side of the packaging interior opposite a packing product removal opening can be closed with a cîosure tab.
In this embodiment, the packing product or a tablet can be removed from the packaging interior exclusively through a packing product removal opening. An unintentional removal or falling oui of the packing product from the packaging interior can thus be successfully prevented.
In a further advantageous embodiment of the packaging according to the invention, the at least one packing product removal opening ofthe packaging interior can be closed with a closure tab. In this version of the packaging the closure tab of the packing product removal opening must be additionally opened in order to remove the packing product already présent in the packaging interior from the packaging with the resuit that the degree of rétention ofthe packing product is further increased.
It can be particularly expédient in a packaging according to the invention if the at least one backing card is a further blister card with a carrier film with at least one blister cavity for receiving packing product, in particular for receiving a pharmaceutical active substance formulation such as a tablet, as well as a cover film, wherein the at least one further blister card is arranged so that its carrier film forms an outer surface of the packaging and its cover film is oriented towards the packaging interior.
This packaging design affords the ad va nia ge that at least one further blister card is used as backing card for protecting the ai least one “first’’ blister card. Thus, two blister cards are arranged in a mirror-inverted rnanner with respect to one another and in the securing position mutually protect their cover films resting on one another from unintentional pushing oui of the packing product from the blister cavities. This design is particularly economical since the further blister card in iis function as backing card can be constructed of the same material or the same matériels as the at least one first” blister card. Depending on the configuration of the packaging according to the invention, it is possible that no préférable arrangement or position of the at least one first” blister card and the one or plurality of further blister cards which serve as backing cards can be identified on the backing cards. In this preferred embodiment the interconnected blister cards can, for example, be configured identically and/or arranged symmetricaliy relative to a packaging axis and/or a packaging plane. Such a packaging in which two or more blister cards are provided offers a further advantage since the largest possible number of dose units of the packing product can be packed in the blister cards in a small packaging space.
Particularly expedientiy in a packaging according to the invention in the securing position, the blister cavities filled with packing product of two blister cards resting on one another can be arranged congruêntly above one another. In this embodiment, the blister cavities of two corresponding blister cards which in the securing position of the packaging rest with their cover films on one another lie congruêntly above one another. In this embodiment of the packaging, a particularly safe storage of the packing product can be achieved which is protected against unintentional pushing through of the cover films.
Altematively to this, it can also be provided within the scope of the invention that in the securing position the blister cavities filled with packing product of two blister cards resting on one another can each be arranged offset with respect to one another. Also in this embodiment of the packaging, the packing product can be reliably protected against unintentional pushing through of the cover films.
In a particularly pleasing embodiment of the packaging according to the invention, the packaging can be configured to be cushiomshaped, wherein the two outer surfaces of the packaging are either formed by a first blister card and a further blister card with packing product filled in blister cavities or altematively by one blister card and by an opposite backing card without packing product, which are interconnected at two opposite side edges of the blister card, wherein the side edges form the long sides of the packaging and mirror-inverted overlapping closure tabs are fastened on the mutually opposite narrow sides of the blister cards in each case.
The mirror-inverted overlapping dosure tabs on the narrow sides of the packaging can advantageously serve as first and second mutually opposite and spaced apart packaging portions which must be compressed in a mirror-inverted manner for fixing the cushion-like packaging in its removal position, in the securing position the packaging is substantially fiat and the two outer surfaces or outer sides lie with their inner sides on one another. As a resuit of compression on the narrow sides of the packagings this arches in a cushion shape and in the removal position forms a packaging interior which has an approximately oval cross-section. Expediently the closure tabs on the narrow sides of the packaging are trimmed accordingly in an oval rounded manner.
A further pîeasing packaging variant according to the invention can be configured as a straight prism with an even number of outer surfaces, wherein the outer surfaces are formed by one or more blister cards with packing product filled in blister cavities or aiternatively by at least one blister card and by one or more backing cards without packing product which are connected at their opposite side edges arranged next to one another and form the long sides of the packaging.
For example, four, six or eight blister cards or aiternatively also backing cards without packing product can be combined in a strip-like manner as outer surfaces of a straight prism. The blister cards and/or backing cards are in this case connected at their long side edges with the respectively adjacent biister cards and/or backing cards. In order to increase the mobiiity of the blister cards and/or backing cards arranged next to one another in a strip-like manner, the long side edges thereof can be implemented as fold edges and/or hâve perforations for weakening the material of the carrier films.
Depending on the requirement for the packaging, individuai, several or ail the outer surfaces of the packaging prims can be configured as blister cards and hâve the same or different numbers of blister cavities. For example, in a hexagonal prism every other outer surface can be configured as a strip-shaped blister card with blister cavities wherein altemately the outer sides provided in each case between two blister cards are implemented as backing cards without blister cavities.
Particuiarly advantageously in a packaging according to the invention, a distance between mutually opposite packaging portions in the securing position can be greater than the distance between the same mutually opposite packaging portions in the removal position. As has already been noted, by suitable dimensioning of the packaging dimensions, it can be ensured that the distance between mutually opposite packaging portions in the securing position which must be compressed to transfer the packaging, for example, by moving, shifting, foiding and/or pivoting into the removal position, is suffîcîently large so that these two packaging portions cannot be gripped by an infants hand.
Since in this embodiment the distance between the same mutuaily opposite packaging portions in the removal position is smaller than in the securing position, seniors or blind people or visuafly impaired persons can easily recognize in which of the two réversible positions the packaging is located. Advantageously the user friendliness of the packaging is thus further increased.
For example, it can be expédient for a child-resistant packaging if the distance between mutuaily opposite packaging portions in the securing position is at least 8 cm, preferably at least 10 cm. These securing distances in the securing position between mutuaily opposite packaging portions which must be compressée! to transfer the packaging into the removal position seem to be sufficiently large for infant hands according to the présent knowledge of the applicant. Seniors however should be abie to grasp these securing distances with the span width of one hand,

The now-followîng general description of the figures relates generaliy to ail the figures 35 shown. In the following the same reference numbers are used in each case for the same or comparable éléments of the packaging for the different embodiments.
Figures 1 to 7 each show different embodiments of cushion-shaped packagings 1 in each case, which each hâve two outer surfaces 2 or outer sides 2 of the packaging 1 which are interconnecied along the long sides 3 of the packaging 1. Closure tabs are arranged on the opposite narrow sides 4 and the opposite narrow sides 4 are characterized as mutually opposite packaging portions, namely as first packaging portion 5 as well as second packaging portion 6 opposite to this, wherein these packaging portions 5, 6 must be compressed by hand in order to transier the packaging 1 from a securing position 70 into a removal position SO. Depending on the design and application of the packaging, the packaging portions 5 and 6 can be marked directly and characterized as actuating portions. Altematively to this, these packaging portions 5 and 6 can also only be characterized in separately enclosed usage instructions for using the packaging, with the resuit that the child-resistant design of such a packaging is further increased, Naturally the packaging portions 5 and 6 can be characterized both directly on the packaging and also in usage instructions.
The cushion-shaped packaging 1 comprises in each case a blister card 10 with a top side 11 and an underside 12. As already noted initially, the désignations of a top side 11 and an underside 12 of the blister card 10 opposite the top side 11 selected herelnafter merely serve to simplify and refine the assignment ofthe relevant sides. The blister card 10 is arranged in relation to the packaging 1 so that the top side 11 thereof forms an outer side 11 of the blister card 10 or an outer surface 2 of the packaging 1. Conversely the underside 12 of the blister card 10 forms an inner side ofthe packaging 1.
The blister card 10 shown in Fig. 1 is here configured to be substantially rectangular and has a long side 13 and a narrow side 14. The blister card 10 comprises a carrier film 20 which is arranged in Fig. 1 on the top side 11 or the outer side 11 of the blister card 10 and thus also forms an outer surface 1 of the packaging 1. The carrier film 20 is produced, for example, from transparent plastic and has a film thickness 21, for example, of about 200 pm (micron). The carrier film 20 has fold edges 22 and/or perforations 23 or weakening lines 23 in order to be folded, folded or bent along these defined edges or weakening lines. The carrier film 20 has blister cavities 25 for receiving packing product 40. In the packaging 1 illustrated in Fig. 1, for example, a total of ten blister cavities 25 for receiving packing product 40 are arranged on the blister card 10 in two parallel rows of respectively five blister cavities 25. The packing product 40 is illustrated here for simplicity as single tablets 41 in each case.
A cover film 30, for example, made of aluminium is attached to the underside 12 of the blister card 10, wherein the cover film 30 has an exemplary film thickness 31 of about 20 ,um (micron). The cover film 30 is connected at least in sections extensively to the carrier film 20 leaving the blister cavities 25 free. For example, the cover film 30 is connected to the carrier film 20 by sealing or by adhesive bonding. The push-through direction 35 of the cover film 30 is characterized by an arrow 35, in order to remove the tablets 41 located therein through the cover film 30 from the blister card 10 by pushing in the direction of the arrow 35 from above or from outside onto the blister cavities 25 of the carrierfiîm 20. The coverfilm 30 is destroyed in so doing.
In order to prevent the packing product 40 or the tablets 41 from being able to be removed from the blister card 10 unintentionally or unauthorized, for example, by infants, according to the invention on two opposite side edges 15, 16 of the blister card 10 a backing card 50 for protecting the coverfilm 30 of the blister card 10 is fastened movably thereon. In the embodiments shown in Figures 1 to 7 the first side edge 15 here is a first long side edge 15 of the blister card 10. Likewise the second side edge 16 is a second long side edge 16 of the blister card 10. Closure tabs 60 are arranged in each case on the narrow sides 4 of the packaging 1.
Figure 2A shows a packaging 1 according to the invention in cushion form, wherein in this packaging a blister card 10 with a row of blister cavities 25 for receiving tablets 41 is arranged on the packaging top and a backing card 50 without blister cavities is provided on the packaging underside. In a securing position 70 of the packaging 1 the backing card 50 rests on the underside 12 of the blister card 10 on the cover film 30 attached there. In the securing position 70 the backing card 50 thus serves as a cover card for protecting the sensitive cover film 30 on the underside 12 of the blister card 10. The backing card 50 is here fabricated from a carrier film 55 which is fabricated from the same material as the carrier film 20 of the blister card 10 and is connected to this carrier film 20 along the first long side edge 15 and along the second long side edge 16. The backing card 50 has a top 51 or outer side 51 which forms an outer surface 2 of the packaging 1. The backing card 50 has an underside 52 opposite the top 51 which forms an inner side 52 of the packaging.
Within the scope of the invention it is also provided that for exampîe, the backing card 50 is made from a section of the carrier film 20 of the blister card 10 and thus the carrier films of the blister card 10 and the backing card 50 are integraily connected to one another. That portion of the carrier films which forms the backing card 50 for protecting the cover fiîm 30 of the bîister card 10 can, for exampîe, be folded over at a side edge 15 of the blister card 10 to form a fold edge 22 and can be adhesively bonded or heat-sealed to the carrier film 20 thereof on the opposite side edge 16 of the blister card 10.
Figure 2B shows in a side view the narrow side 4 of the structure of this packaging 1 illustrated in Fig, 1 wherein a blister card 10 with blister cavities 25 for receiving tablets is arranged on the packaging top side and a further blister card 56 is provided as backing card 50 on the packaging underside, in this further blister card 56 blister cavities 57 for receiving tablets 41 are also arranged in two parallel rows next to one another. The blister card 56 comprises a carrier film 55 5 which is here connected integrally to the carrier film 20 of the blister card 10. Along the first long side edge 15 of the packaging 1, the carrier films 20 and 55 are folded over at a latéral distance from the cover films 30 and 58 to form fold edges 22. In the area of the opposite second long side edge 16, the two carrier films 20 and 55 are heat-sealed together to form an inscription tab 120. The carrier films 20 and 55 here for example are 10 made of a translucent, transparent plastic. The cover films 30 and 58 are made, for example, of an aluminium composite film. As a resuit of the mirror-inverted arrangement of the two blister cards 10 and 56 - the sensitive cover films 30 and 53 lie oriented towards one another protected inside the packaging - the further blister card 56 with the carrier film 55 lying on the outer side thus serves as a cover card for protecting the 15 sensitive cover film 30 on the underside 12 of the blister card 10 and for protecting its own cover film 58. The carrier film 20 has fold edges 22 and/or perforations 23 or weakening fines 23 in order to be able to be folded, folded or bent along these defined edges or weakening fines.
Figure 3 shows the long side 3 of the embodiment of the packaging 1 in cushion form 20 according to the invention illustrated in Fig. 1 or in Fig. 2B, wherein the packaging 1 is located in its securing position 70 in this diagram. The cover film 58 of the further blister card 56 which serves here as backing card 50 rests on the opposite cover film 30 of the blister card 10. In this second position 70 it is not possible to push through the blister cavities 25, 57 in the push-through direction 35 from outside. The two mutually opposite 25 packaging portions 5 and 6 on the opposite narrowsides 4 ofthe packaging 1 are located in the fiat securing position 70 of the packaging 1 at a maximum distance from one another at a distance 7.
Figure 4 shows the packaging 1 in cushion form illustrated in Fig. 2B or in Fig. 3, wherein in this diagram the packaging 1 is located in its removal position 80 fixed by compressing 30 by hand in the direction of the arrow 90. The extemai application of force 90 by mirrorinverted compression is symbolized by the two opposite arrows 91 and 92 which are intended to illustrate the directions of pressing, for example, by thumb and index finger ci one hand of the user of the packaging 1. Compared to the distance 7 in the securing position 70 shown in Fig, 3, here sn Fig. 4 the distance 8 between the two opposite 35 packaging portions 7 and 8 in the removal position 80 is significantly reduced or shortened. The two packaging portions 7 and 8 which must be compressed in the cushion packagings shown here are the latéral closure tabs 60 in each case. As a resuit of the extemal application of force 90, the cushron-shaped packaging 1 bulges out to form a packaging inierior 100. This has the resuit that during compression 90 of the closure tabs 60 from outside, as along as the packaging 1 is therefore fixed with one hand in its removal position 80, the blister card 10 and the backing card 50 or here the further blister card 56 do not rest on one another at their undersides or inner sides 12 and 52 and therefore the tablets 41 can be removed from the blister cavities 25, 57 by pushing through 35 the blister cards or blister strips with the other free hand.
Figure 5 shows in an oblique view from above the packaging interior 100 of the packaging 1 illustrated in Fig. 4, wherein in this diagram the packaging is tocated in its emptying position 130 fixed by latéral compression. A tabiet 41 which had already been removed from the blister cards in the removal position 80 and pushed through into the packaging interior 100, can be removed from the packaging 1 after gripping and opening the latéral closure tabs 60 in the emptying position 130. For fixing the packaging 1 in this emptying position 130 the packaging must be compressed on its long side edges 15, 16 in the pushing direction 140 symbolized by two opposite arrows 140,
The opened closure tabs 60 here form an approximately oval removal opening 110 for the packing product 40. Practically tablets 41 can thus be emptied from the packaging interior 100 in a contact-free manner into the mouth of the user.
Figure 6 shows the packaging 1 after emptying a tabiet 41 as dose unit of the packing product from the packaging interior 100.
Figure 7 shows a further embodiment of a packaging 1 in cushion form according to the invention wherein here the closure tabs 60 on the left Harrow side 4 of the packaging 1 are heat-sealed together in sections 61. Thus, only the closure tabs 60 on the right narrow side 4 of the packaging are avaiiable as removal opening 110 for the tablets 41 after opening.
Figures 8 to 11 show a further embodiment of a packaging 1 according to the invention in which on the packaging underside, a backing card 50 is fastened movably in a foldable manner by means of connecting tabs 65 in the form of a plurality of connecting webs arranged in sériés on two opposite peripheral portions 17 and 18 ofthe blister card 10, Figure 8 shows this packaging 1 in its securing position 70. Both the blister card 10 and also the backing card 50 which here is a further blister card 56, each hâve a first peripheral portion 17 along the long side edges thereof and opposite a second peripheral portion 18, wherein several connecting tabs 65 are fastened in these peripheral portions 17 and 18 between the blister card 10 and the backing card 50. Depending on the length of these connecting tabs 65 or connecting webs, the two interconnected éléments, Le. the blister card 10 and the backing card 50 can be transferred from their securing position 70 into their removal position 80, which is illustrated in Fig. 11, by latéral compression on the first packaging portion 5 and on the second packaging portion 6. The blister card 10 and the backing card 50 are each formed in the shape of U-profiles, wherein fold edges 22 running parallel to one another in the longitudinal direction of the packaging 1 serve to increase the stiffness of the blister card 10 or the backing card 50.
Figure 9 shows in a sectionai view according to the line of intersection IX-fX sketched in Fig. 8 from the side a detail of the packaging 1 illustrated in Figure 8. The cover films 30 and 58 of the blister card 10 or the further blister card 56 in their function as backing card 50 for the blister card 10 at the top in the diagram rest directiy on one another in the securing position 70. In the purely schematic Fig. 9 an apparent air space or distance between the blister card 10 and the backing card 50 is shown mereîy for clearer représentation. As soon as an attempt is made in this securing position 70 to remove tablets 41 from the packaging 1 from outside by pushing through 35 the blister cavities 25 or 57, the two cover films 30 and 58 rest on one another in each case and altemately and mutually stabilize or protect one another before these can be pushed through. That state applies synonymously aiso to the diagrams in Figs. 2A, 2B, 12 and 16 where in each case to better représent fine packaging function in its securing position 70, layers of the blister cards 10 resting on one another and backing cards 50 assigned to these are illustrated apparentîy with an Interposed spacing. As stated, this mereîy serves for simpler représentation and assignment of individual layers to the respective éléments of the packaging.
Figure 10 shows the long side of the packaging 1 illustrated in Fig. 8 and Fig. 9 du ring transferfrom the securing position 70 into the removal position 80 of the packaging I.The direction of movement 95 which is brought about by externe! application of force 90 by mirror-inverted compression or dispiacement 91,92 by means of two fingers of a hand of the user is symbolized by the double arrow 95,
Figure 11 shows the long side of the packaging 1 illustrated in Figures 8 to 10 in their compressed removal position 80. The upper blister card 10 is here located at a distance from the backing card 50 forming a packaging interior 100.
Figures 12 to 15 relate to a further embodiment of a packaging 1 according to the invention in the form of a hexagonal straight prism.
Figure 12 shows this packaging 1 according to the invention in the form of a hexagonal straight prism in a spread-oubflat securing position 70. In order to increase the movability of the blister cards 10 and/or backing cards 50, 56 arranged next to one another in a strip-like manner, the long side edges are executed as fold edges 22. Altematively or in addition to the fold edges 22, perforations 23 or weakenîng fines 23 can also be provided for weakenîng the material of the carrier films 20, 55.
Figure 13 shows this packaging 1 in its compressed removal position, wherein the view into the packaging interior 100 of the prism-shaped packaging 1 is exposed.
Figure 14 shows this packaging 1 with dosure tabs 60 bent over on the narrow sides of the packaging 1. For fixing the packaging 1 in this emptying position 130, the packaging must be compressed on its long side edges 15, 16 in the pressure direction 140 symbolized by two opposite arrows 140.
Figure 15 shows in a side view the packaging illustrated in Figures 12 to 14 in its compressed removal position 80.
The two Figures 16 and 17 relate to a further embodiment of a packaging 1 according to the invention in the form of a blister card 10 and â backing card 50 which is also executed as a further blister card 56. The two blister cards 10 and 56 in their securing position 70 lie congruently in a mirror-inverted manner above ons another and are connected along their two iong side edges 15, 16 to inscription tabs 120 which form the peripheral portions 17, 18 of the blister cards 10 and 56.
Figure 16 shows this packaging 1 according to the invention in its securing position 70.
Figure 17 shows in a side view the narrow side of the packaging illustrated in Fig. 16 in its compressed removal position 80. Advantageously for this purpose the two inscription tabs 120 can be roughened, for example, so that these can be gripped more easily for the user and compressed. At the same time, these inscription tabs 120 can be constituted by means of corresponding design measures such as, for example, comparatîvely Sharp outer long edges so that these are perceived to be unpieasant when touched by infants. As a resuit, Infants are additionafiy deterred from compressing the packaging 1 by
The packagings 1 shown here each comprise blister cards 10 or backing cards 50 which hâve substantially rectangular contours. However, the invention is not restricted to rectangular or strip-shaped blister cards 10 or backing cards 50 but naturally, for example, square, circuler or elliptical blister cards 10 or backing cards 50 can also be used for a packaging 1 according to the invention.
The further Figures 18 to 25 are explained in detail in the following:
Figure 18 shows a further embodiment of a packaging 1 according to the invention in cushion form, wherein the packaging 1 is illustrated here în its securing position 70. On the top side of the packaging 1 or on the top side 11 of the blister card 10, a removal opening 110 for the packing product is stamped into the carrier film 20 lying at the top here. The backing card 50 which is fastened along two opposite long side edges 15. 16 on the blister card 10 and which in the securing position 70 rests on the underside 12 or on the inner side of the blister card 10, is made from a section of the carrier film 20 of the blister card 10. The carrier films 20, 55 of the blister card 10 and the backing card 50 are connected integrally to one another. The blister card 10 lying at the top in the figure here, 5 for example, comprises two rows of blister cavities 25 for receiving packing product 40.
Specifically here, for example, seven tablets 41 are packed in the blister card 41 lying at the top. The removal opening 110 in Oie carrier film 20 at the top is here stamped out in a circulai shape and is arranged on a corresponding section of the carrier film 20 of the blister card 10 before heat-sealing the two carrier films 20 and 55 to form a latéral 10 inscription tab 120. In this embodiment the corresponding opposite section of the carrier film 55 of the backing card 50 is not stamped or deformed. The removal opening 110 is here advantageously positioned so that a section of the stamped-out removal opening 110, for example, about half the cross-section of the circular removal opening 110, is arranged in the région of ths latéral inscription tab 120. This has the advantage that thus 15 only approximateiy the remaining other half of the removal opening 110 is available as free cross-section for removal of packing product 40 and in the securing position 70 of the packaging 1 the removal opening 110 is reliably closed. Latéral closure tabs 60 on the two mutually opposite narrow sides 4 of the packaging 1 are each heat-sealed together along sections 61. The stamped-in removal opening 110 is thus the only opening of the 20 packaging 1 for removal of packing product.
in the removal position 80 ofthe packaging 1 as illustrated in Fig. 19 the removal opening 110 here in the form approximateiy of a semicircle adjacent to the inscription tab 120 is opened in the région of the blister card 10. This has the advantage that the removai opening 110 is as small as possible in order to ensure only the removal of a single 25 packed product 40 or a single tablet 41. Depending on the selected film thickness 21 of the carrier film 20, the edge of that half of the stamped-out circular removal opening 110, which is heat-sealed in the région of the inscription tab 120 to the carrier film 55 of the backing card 50, acts as a boundary edge for the removed packing product 40.
Depending on the design, the removal opening 110 stamped into the carrier film 20 can 30 also differ from a circular shape and for example, be formed in the form of a rectangle, a square, an ellipse or a polygonal curved fine. Likewise, the proportion of the removai opening 110 which in the heat-sealed position of the finis'ned packaging 1 cornes to lie in the région of the inscription tab 120 and therefore is not available as free cross-section for actual removal of the packing product can vary. For example, the removal opening 35 110 can be entirely arranged on that section of the carrier film 20 of the blister card 10 which does not form the inscription tab 120 but i$ actuaily available as a free removal cross-section with the packaging interîor 100. Likewise, it can be expédient to position the removal opening 110 so that only a spécifie section of the removal opening 110, for example, only a quarter or a third of the area of the stamped removal opening 110, cornes to lie in the région of the inscription tab 120 but the remaining free cross-section is available for actuai removal of the packing product 40 from the packaging interîor 100.
Figure 20 shows in a detailed view from the front a further embodiment of a packaging 1 according to the invention in cushion form, wherein the packaging 1 is illustrated here in ifs removal position 80 and on the top side a removal opening 110 for the packing product 40 is stamped into the carrier film 20 of frie blister card 10 shown at the top. In this packaging 1 both the inscription tab 120 protruding to the right in the diagram and also the ciosure tabs 60 on the opposite narrow sides 4 of the packaging 1 are provided with inscriptions. The inscriptions can, for example be printed or glued on the carrier films or on the outer surfaces 2 of the packaging. The latéral ciosure tabs 60 are heat-sealed together along sections 61. In this embodiment the stamped in removal opening 110 is the only opening for removal of packing product.
Figure 21 shows a detail of a further embodiment of a packaging 1 according to the invention in cushion form, wherein a removal opening 110 for the packing product 40 is stamped into the carrier film 20 iyîng at the top here. That section of the opposite lower carrier film 55 of the backing card 50 which corresponds with the removal opening 110 in the carrier film 20 is deep-drawn here and advantageously forms a chute for the packing product 40. With reference to Fig. 18 here also the removal opening 110 is advantageously positioned so that approximately half of the stamped-out removal opening 110 is arranged in the région of the latéral inscription tab 120.
A single packing product 40, for example, a tablet 41 can only be removed individually from the removal opening 110 and thereby enters into the deep-drawn section of the carrier film 55 in the région of the inscription tab 120 which acts like a chute or slide for the individual packing product 40. The edge ofthe deep-drawn recess ofthe lower carrier film 55 here acts as a dam for the packing product 40 and prevents the unintentional loss of the removed packing product 40 during removal before this is grasped by the user.
Figure 22 shows in an oblique view a detail of a further embodiments of a packaging 1 according to the invention in cushion form which is illustrated in its removal position 80. Both mutually opposite carrier films 20, 55 are stamped through here after laminating the inscription tab 110. The removal opening 110 is in this case positioned so that a section of the stamped-out removal opening 110, for example, half of the circular removal opening 110, is arranged in the région of the latéral inscription tab 120. Thus, the removal opening 110 obtained by stamping through both carrier films 20, 55 has the advantage that the free long edge of the inscription ta b 120 is also continue us in the area of the removal opening. It is thus ensured that in the removal position 80, in each case only a single packing product 40 or a single tablet 41 can be removed from the packaging 1 through the removal opening 110. The continuons free long edge of the inscription tab 120 here acts as a clamp for that packing product 40 or that tablet 41 located just inside the removal opening 110. Depending on the selected position and the proportion of the removal opening 110 which is positioned in the région of the inscription tab 120 an undesired falling out of packing product 40 from the removal opening 110 can thus be prevented. In order to further increase the safety as child-resistani packaging 1, the continuous free long edge of the inscription tab 120 is here designed to be jagged or roughly structured, for exampie, which is particuiarly perceived as unpleasant when grasped by chiîdren.
Figure 23 illustrâtes in a side view a further embodiment of a packaging 1 according to the invention in cushion form wherein a fold-out package insert 121 is fastened to the inscription tab 120. The package leaflet 121 is here, for example, adhesively bonded in a captive manner to the inscription tab 120 by means of an adhesive film and folded in a pull-out manner like a concertina. Figure 23 shows the package leaflet 121 in the foldedout position.
Figure 24 shows in a front view a further embodiment of a packaging 1 in cushion shape according to the invention, wherein the packaging 1 is illustrated in its securing position 70 and the inscription tab 120 is fitted with a tear-off removal securing device 125. The removal securing device 125 serves to ensure that the packaging 1 is secured in its securing position 70 until the removal securing device 125 is removed or opened. As removal securing device 125 the inscription tab 120 has respectively perforations 23 or weakening lines 23 of the carrier films 20, 55 along the long side edge 16 of the blister card 10 and the backing card 50 arranged thereunder, which extend from the mutually opposite narrow sides 4 of the packaging 1 along a section of the long side edge 16. The sections of the perforations 23 or weakening lines 23 along the long side edge 16 must first be torn off before the packaging 1 is transferred into its removal position 80 in the manner already described previously by external application of force 90 by mirror-inverted compression 91, 92 of the two mutually opposite packaging portions 5, 6 and the removal opening 110 stamped into the upper carrier film 20 is tous opened. The latéral dosure tabs 60 on the narrow sides 4 are heat-sealed together along sections 61. In this embodiment the stamped-in removal opening 110 is the only opening for removal of packing product.
The two outer wings or sections of the inscription tab 120 can be removed after tearing open the perforations 23 along the long side edge 16 by then further tearing open along weakening Unes 23 which, for exarnpie run obliqueiy in the direction of the free long edge of the inscription tab 120. In Fig. 24 the inscription tab 120 here has a hanging opening 126 approximately in its longitudinal centre which is used for hanging the packaging 1 for exemple on a sales stand.
Figure 25 illustrâtes in a detailed view a further embodiment of a packaging 1 according to the invention in cushion form, wherein the packaging 1 is illustrated in its removal position 80 and on the packaging top side a removal opening 110 for the packing product is stamped into the carrier film 20 lying at the top. The removal opening 110 is here advantageously arranged transversely to the longitudinal direction of the packaging and for example, has an approximately rectangular contour. In this variant, the removaî opening 110 is only stamped out along three sides maintaining an edge distance from the carrier film 20. The fourth side, preferably a long side of the rectangular contour is not stamped out or stamped through but is merety machined to form a weakening line 23 or a perforation line 23 of the carrier film 20, Altematively qf in addition to the perforation 23 the contour along this fourth side can also be provided with a fold edge 22. Thus, a movable foldable closure tab 60 remains inside the removal opening 110 which remains along one side of the removal opening 110 connected to the adjacent carrier film 20 to form a fold edge 22 and/or a perforation line 23. This foldable closure tab 60 ensures that for the case where the packaging 1 is located in its securing position 70 the removal opening 110 is closed. As soon as the packaging 1 is transferred into its removal position 80 as a resuit of an extemal application of force 90 by means of mirror-inverted compression 91, 92 of the two mutually opposite packaging portions 5, 6, the removal opening 110 stamped into the upper carrier film 20 thus opens and the foldable closure tab 60 folds inwards into the packaging interior 100 along the weakening line 23 or perforation 23 and/or the fold line 22 and thus automatîcally exposes the removal opening 110.
