Abstract
The invention relates to a child-proof peelable bag with sealable edges (10), comprising at least two lengths of packing material (1,2), the surfaces of which are sealed together by means of a sealing edge (3) and which have a holding aid (4) projecting outwards from the sealing edge (3). The peelable bag is characterized in that the relative flexural strengths of the lengths of packing material (1, 2) differ to a comparatively large extent and that the holding aid (4) of, for example, the length of packing material (1) having the greater flexural strength has a break line (5) in the area of the sealing edge (3).
Description
Peelable side-sealed bag of child-proof design, method for its production and its use The invention relates to a peelable side-sealed bag of child-proof design, comprising at least two packaging material web sections sealed flat against each other by a sealing edge and having a gripping aid arranged outside the sealing edge, together with a method for its production and its use.
It is known that, in order to comply with the important "child-proof" property, for example in a bag-type packaging, it is necessary to use at least one but customarily two packaging material webs of high tear-strength to produce the packaging. These must also have an appropriate barrier property relative to the packaging. In addition, in order to achieve the necessary barrier function, the sealing edge of the packaging bag must be formed by a strong and tightly sealed weld seam extending uninterrupted around the bag. In such cases, in order to achieve a peel property at tight weld seams, sealants or combinations of sealants specifically adapted to this such as PE-peel, peel coatings, etc. are to be used.
Packaging with a child-proof seal such as blister strips, blister cards and blister tapes are also known which are suitable for solid medicinal products and can be opened without a tool. The packaged material contained in these packagings, consisting of products such as tablets, pills or capsules, must be insensitive to pressure since it has to be pressed out of the packaging by force, through a covering usually consisting of aluminium foil, and removed.
It is known in professional circles that a number of States are currently considering the introduction of binding legislation mandatorily prescribing child-proof packagings for a number of active substances. This applies especially to medicinal products which, as a result of the toxic effect of their formulation represent a serious risk if incorrectly taken, and especially in the case of children.
In the case of medicinal products which, because of their structure and use, are flexible and pressure-sensitive, it is impossible to press them through the packaging as described above . On the other hand, it is regarded by the majority of patients as disadvantageous and inconvenient if the opening of a child-proof bag-type packaging requires the assistance of a tool such as, for example, scissors or a knife.
The object of the invention is to provide a packaging for flat, flexible and pressure-sensitive medicinal products which can be opened without a tool but is also child-proof, during opening of which the exertion of pressure has to be reliably avoided but which requires no auxiliary tools in order to open it.
The obj ect is achieved by the invention, in the case of a peelable side-sealed bag of the type indicated in the precharacterizing clause of Claim 1, by the design of the packaging material web sections indicated in the characterizing clause of Claim 1.
As a result of the fact that the relative flexural strengths of the packaging material web sections are designed with a comparatively significant difference, and that in addition the gripping aid of the packaging material web section designed with higher flexural strength possesses a line of weakness extending in the region of the sealing edge, it is possible, by selectively bending along the line of weakness, to break open the contents of the two packaging material webs and thus expose a gripping tab for further peeling along the sealed edges.

The obj ect is achieved by the invention, in the case of a peelable side-sealed bag of the type indicated in the precharacterizing clause of Claim 1, by the design of the packaging material web sections indicated in the characterizing clause of Claim 1.
As a result of the fact that the relative flexural strengths of the packaging material web sections are designed with a comparatively significant difference, and that in addition the gripping aid of the packaging material web section designed with higher flexural strength possesses a line of weakness extending in the region of the sealing edge, it is possible, by selectively bending along the line of weakness, to break open the contents of the two packaging material webs and thus expose a gripping tab for further peeling along the sealed edges.
Because the gripping aid does not yield when subjected to tensile stress but only becomes accessible by the trick involving bending for subsequent peeling, security against opening during play is provided, at least for children's hands and without knowledge of the necessary bending function.
One embodiment envisages that a region of the gripping aid close to the sealing edge is free of sealant or unsealed.
As a result, in the course of bending, a starting point or gripping tab for further peeling along the sealing edges becomes more readily accessible.
Provision is also advantageously made for a through punching forming a gripping tab to be provided in the packaging material web section of lower flexural strength, following the distance from the outer contour of the gripping aid and, depending on the material combination, with or without retention points.
The effect of these retention points is that, if the gripping region is bent in the course of play, the peeling tab provided for opening still reliably adheres to the respective other web of packaging material. Only by direct, deliberate bending over of the tab about the line of weakness in the web of higher flexural strength are the retention points in the more flexible web overstretched and broken open. As a result, a gripping tab is formed or exposed.
The retention points may take the form of interruptions in the punched line or, for example, comparatively small sealed areas adjacent to the punched line. The number, type and size of these retention points are to be selected for each specific material and as a function of the size and geometry of the gripping tab.

The measure serves both to increase child-proof security and to facilitate further handling in the peeling of the side-sealed bag. As a result, in contrast to known child-proof but in many cases unpeelable side-sealed bags according to the prior art, opening without tools or other aids becomes possible, while the desired property of child-proof security is achieved by a special design of the gripping aid, by means of a line of weakness in the packaging web section of higher flexural strength and the punching-out of a gripping tab in the packaging material web section of lower flexural strength, in accordance with the teaching of the invention.
Further expedient and/or advantageous embodiments of the invention are provided according to the subclaims.
A method for the production of a side-sealed bag of the type indicated initially, in which a packed material is inserted between halves of a packaging having sealing edges and a gripping aid and the halves are welded together, is characterized in that one of the halves is formed from material of comparatively low flexural strength and the other half from a material of, comparatively, significantly greater flexural strength, or vice versa, and in that whichever is the material half of greater flexural strength is designed with a line of weakness in the starting region of the gripping aid.
In this method, a punched portion is made in the packaging material web section designed with lower flexural strength, following the outer contour of the gripping aid at a distance, to form a gripping tab.
The peelable side-sealed bag of child-proof design can be used according to the invention for flat, pressure-sensitive forms of medicinal products and especially for transdermal therapeutic systems.
Further expedient and/or advantageous embodiments of the invention are provided according to the subclaims.

The peelable side-sealed bag of child-proof design can be used according to the invention for flat, pressure-sensitive forms of medicinal products and especially for transdermal therapeutic systems.
Details, features and advantages of the invention are apparent from the explanation which follows of an example of the embodiment shown diagrammatically in the drawings, in which:
Figure 1 shows a circular packaging according to the invention in a plan view, Figure 2 shows a rectangular packaging with the arrangement of a gripping aid in a corner region, again in plan view, Figure 3 shows a similarly rectangular packaging with a marginal gripping aid, Figure 4 shows a detailed view with a gripping aid (and in the region of the latter, a punched-out portion for a gripping tab with interruptions in the punch line according to Figure 3), and Figure 5 shows examples of retention points for the connection of top and bottom webs, with defined release, in the region of a gripping tab in the form of mini-sealing points.
Figure 1 shows an example of embodiment of a circular packaging in the form of a side-sealed bag 10 of child-proof design and with particular suitability for the packaging of a circular TTS (not shown) or another flat form of medicinal product, comprising at least two packaging material web sections 1,2 sealed flat against one another by a sealing edge 3 and a gripping aid 4 projecting outwards from the sealing edge 3 and partially sealed as indicated by the hatching.
It is important here that the relative flexural strengths of the packaging material web parts 1,2 are designed with relatively significant differences, and that the gripping aid 4 of the packaging material web part 1 designed with greater flexural strength has a line of weakness 5 extending in the region of the sealing edge. The line of weakness is characterized by a straight dotted line.
It extends approximately tangentially in the region of the sealing edge 3 and is prepared in a known manner, for example by perforation, punched notches, scoring, thermal embrittlement, etc., to form a defined intended breaking point. It is relevant to functioning that one packaging material web section is rigid and the second relatively flexible. The relatively more flexible packaging material web section 2 or its retention points 9, 9a to 9c (Figs. 3 and 5) are overstretched by the bending of the relatively more rigid packaging material web section 1 and are thereby separated and the peel tab 8 thus exposed. Which of the two web sections is rigid and which is less rigid is fundamentally unimportant for functional purposes. In the example shown, for reasons of better ease of manipulation and on the basis of experience, the arrangement made is that the lower web 1 is the rigid web and the upper web 2 the flexible web. In this arrangement, in order to open the bag, the gripping aid 4 is folded over downwards, the upper packaging material web section 2 being stretched parallel to the line of weakness 5. As a result of this stretching, the retention points 9, 9a to 9c break open, after which the upper web section 2 can be pulled off without problems by peeling, using the gripping aid 8 which is now exposed, if appropriate after the gripping aid 4 has again been folded over upwards, when the lower web section 1 reliably breaks open along the line of weakness 5.
The two webs are selected, as far as material is concerned, so that they possess a barrier function appropriate to the product, which must also apply to the sealant and the completely tightly closed sealing seam of the sealing edges 3.
_ 7 _ Figure 1 also shows that a region 6 of the gripping aid 4 close to the sealing edge 3 is free of sealant.
This sealant-free region 6 is bordered on the outside by a punched-out portion 7, in the present case in a design resembling a bell curve, whereby a gripping tab 8, initially still secured by retention points 9, 9a to 9c (Figs. 3 and 5) is formed in the upper, more flexible packaging material web 2.
After the gripping aid 4 has been folded up and back to overstretch and break the retention points 9, 9a to 9c, the gripping tab 8 is exposed and can then be used for the further peeling of the peelable side-sealed bag 10, the gripping tab 8 being formed in the upper, flexible packaging material web 2. With the aid of this, after the gripping aid 4 has been folded up and back, the gripping tab 8 can very easily be bent up and can then be used for the further peeling of the peelable side-sealed bag 10.
In an expedient embodiment, which is not apparent from the plan view, at least one of the packaging material web parts 1,2 is three-dimensionally stamped out or deep drawn in the form of a cavity.
As a precondition for security against undesired access by children, further provision is made for the packaging material webs 1,2 to possess, in conjunction with one another, a tear strength selected sufficiently high to prevent access by children.
Provision is also made for sealant to be applied to at least one of the two sealing edges 3.
Because full details of sealants and sealing methods of the prior art are known to the person skilled in the art, no additional details thereof are given at this point but _ g _ qualified sealing in the region of the sealing edges 3 is assumed.
In this arrangement, at least one of the two packaging material web sections 1,2 may be a monofilm.
According to the example of embodiment shown in Figure 1, the packaging 10 may be provided for a circular patch, for example a TTS.
Apart from the circular shape of the side-sealed bag 10, any desired shapes are of course possible and may also be necessary depending on the shape of the packaged material.
For example, Figures 2 and 3 show rectangular formats, but these may also be polygonal or oval. Using the embodiment of a rectangular side-sealed bag 10 as a model, Figure 2 shows a gripping aid 4 arranged cornerwise with an obliquely extending line of weakness 5 in the underlying packaging material web section 1, designed with higher flexural strength. The sealed-on packaging material web section 2 has a punched-out section 7 extending approximately at right-angles (Fig. 3) forming a gripping tab 8. In the example of embodiment according to Figure 3, the gripping aid 4, the course of the line of weakness 5 and the punched-out section 7 and the gripping tab 8 resulting therefrom are provided on a narrow side of the rectangular packaging.
In order to prevent possible premature exposure of the gripping tab 8 and hence unintentional, premature peeling of the packaging material web section 2, interruptions 9 in the cut line may be provided in the course of the punched-out section 7, as shown at a plurality of points in Figure 3. The positioning, size and arrangement of such interruptions 9 may vary according to the specific material. It can always be defined individually for the respective material combination of the packaging materials 1 and 2 in conjunction with the existing packaging dimensions or their geometry and is relevant to the function of tearing open.
To produce retention points 9, 9a to 9c, apart from the examples of embodiment shown in Figure 3 in the form of interruptions of the cut, alternative embodiments in the form of mini-sealing points in sealed regions within the unsealed surface 6 are possible, as shown in Figure 5. Such a mini-sealed retention point is shown there at 9a; an embodiment in which a corner is also sealed is shown at 9b;
9c, however, represents a mini-retention point which has been formed by a "nose" in the sealed seam.
For understanding of the function of the peeling of the relatively more elastic packaging material web section 2, attention is drawn to the fact that the punched-out section 7 preferably extends close to one marginal sealed seam 3 and the gripping tab 8 defined thereby is not sealed to the underlying region 6 of the packaging material web section 1 but secured only by retention points 9 (Fig. 3).
A further alternative embodiment comprises, as shown in Figure 4, giving a punched-out portion 7 to the relatively more rigid web 1 so that a gripping tab 8 is formed in this web 1 which, by upward bending and subsequent peeling of the upper web 2 adhering thereto, permits problem-free opening of the packaging 10.
For greater ease of comprehension, it is pointed out that the co-ordination of the two packaging material web sections 1,2 is within the discretion of the person skilled in the art.
The following alternatives are conceivable:
Lower web (1) rigid/flat Upper web (2) flexible/flat;
Lower web (1) rigid/deep drawn Upper web (2) flexible/flat;
Lower web (1) rigid/deep drawn Upper web (2) flexible/deep drawn;
Lower web (2) flexible/flat Upper web (1) rigid/flat;
Lower web (2) flexible/flat Upper web (1) rigid/deep drawn;
Lower web (2) flexible/deep drawn Upper web (1) rigid/deep drawn.
A method for the production of a peelable side-sealed bag of child-proof design according to the invention, in which a packed material is inserted between halves 1,2 of a packaging 10 having sealing edges 9 and a gripping aid 4 and the halves 1,2 are welded together, provides in accordance with the invention that one of the halves 1 is selected from material of comparatively low flexural strength and the other half 2 from a material of, comparatively, significantly greater flexural strength, or vice versa, and that whichever is the material half of greater flexural strength is designed with a line of weakness 5 in the starting region of the gripping aid 4.
According to the invention, use of the peelable side-sealed bag for flat, pressure-sensitive forms of medicinal products and in particular for transdermal therapeutic systems is envisaged.
Figure 1 shows a circular packaging according to the invention in a plan view, Figure 2 shows a rectangular packaging with the arrangement of a gripping aid in a corner region, again in plan view, Figure 3 shows a similarly rectangular packaging with a marginal gripping aid, Figure 4 shows a detailed view with a gripping aid (and in the region of the latter, a punched-out portion for a gripping tab with interruptions in the punch line according to Figure 3), and Figure 5 shows examples of retention points for the connection of top and bottom webs, with defined release, in the region of a gripping tab in the form of mini-sealing points.
Figure 1 shows an example of embodiment of a circular packaging in the form of a side-sealed bag 10 of child-proof design and with particular suitability for the packaging of a circular TTS (not shown) or another flat form of medicinal product, comprising at least two packaging material web sections 1,2 sealed flat against one another by a sealing edge 3 and a gripping aid 4 projecting outwards from the sealing edge 3 and partially sealed as indicated by the hatching.
It is important here that the relative flexural strengths of the packaging material web parts 1,2 are designed with relatively significant differences, and that the gripping aid 4 of the packaging material web part 1 designed with greater flexural strength has a line of weakness 5 extending in the region of the sealing edge. The line of weakness is characterized by a straight dotted line.
It extends approximately tangentially in the region of the sealing edge 3 and is prepared in a known manner, for example by perforation, punched notches, scoring, thermal embrittlement, etc., to form a defined intended breaking point. It is relevant to functioning that one packaging material web section is rigid and the second relatively flexible. The relatively more flexible packaging material web section 2 or its retention points 9, 9a to 9c (Figs. 3 and 5) are overstretched by the bending of the relatively more rigid packaging material web section 1 and are thereby separated and the peel tab 8 thus exposed. Which of the two web sections is rigid and which is less rigid is fundamentally unimportant for functional purposes. In the example shown, for reasons of better ease of manipulation and on the basis of experience, the arrangement made is that the lower web 1 is the rigid web and the upper web 2 the flexible web. In this arrangement, in order to open the bag, the gripping aid 4 is folded over downwards, the upper packaging material web section 2 being stretched parallel to the line of weakness 5. As a result of this stretching, the retention points 9, 9a to 9c break open, after which the upper web section 2 can be pulled off without problems by peeling, using the gripping aid 8 which is now exposed, if appropriate after the gripping aid 4 has again been folded over upwards, when the lower web section 1 reliably breaks open along the line of weakness 5.
The two webs are selected, as far as material is concerned, so that they possess a barrier function appropriate to the product, which must also apply to the sealant and the completely tightly closed sealing seam of the sealing edges 3.
_ 7 _ Figure 1 also shows that a region 6 of the gripping aid 4 close to the sealing edge 3 is free of sealant.
This sealant-free region 6 is bordered on the outside by a punched-out portion 7, in the present case in a design resembling a bell curve, whereby a gripping tab 8, initially still secured by retention points 9, 9a to 9c (Figs. 3 and 5) is formed in the upper, more flexible packaging material web 2.
After the gripping aid 4 has been folded up and back to overstretch and break the retention points 9, 9a to 9c, the gripping tab 8 is exposed and can then be used for the further peeling of the peelable side-sealed bag 10, the gripping tab 8 being formed in the upper, flexible packaging material web 2. With the aid of this, after the gripping aid 4 has been folded up and back, the gripping tab 8 can very easily be bent up and can then be used for the further peeling of the peelable side-sealed bag 10.
In an expedient embodiment, which is not apparent from the plan view, at least one of the packaging material web parts 1,2 is three-dimensionally stamped out or deep drawn in the form of a cavity.
As a precondition for security against undesired access by children, further provision is made for the packaging material webs 1,2 to possess, in conjunction with one another, a tear strength selected sufficiently high to prevent access by children.
Provision is also made for sealant to be applied to at least one of the two sealing edges 3.
Because full details of sealants and sealing methods of the prior art are known to the person skilled in the art, no additional details thereof are given at this point but _ g _ qualified sealing in the region of the sealing edges 3 is assumed.
In this arrangement, at least one of the two packaging material web sections 1,2 may be a monofilm.
According to the example of embodiment shown in Figure 1, the packaging 10 may be provided for a circular patch, for example a TTS.
Apart from the circular shape of the side-sealed bag 10, any desired shapes are of course possible and may also be necessary depending on the shape of the packaged material.
For example, Figures 2 and 3 show rectangular formats, but these may also be polygonal or oval. Using the embodiment of a rectangular side-sealed bag 10 as a model, Figure 2 shows a gripping aid 4 arranged cornerwise with an obliquely extending line of weakness 5 in the underlying packaging material web section 1, designed with higher flexural strength. The sealed-on packaging material web section 2 has a punched-out section 7 extending approximately at right-angles (Fig. 3) forming a gripping tab 8. In the example of embodiment according to Figure 3, the gripping aid 4, the course of the line of weakness 5 and the punched-out section 7 and the gripping tab 8 resulting therefrom are provided on a narrow side of the rectangular packaging.
In order to prevent possible premature exposure of the gripping tab 8 and hence unintentional, premature peeling of the packaging material web section 2, interruptions 9 in the cut line may be provided in the course of the punched-out section 7, as shown at a plurality of points in Figure 3. The positioning, size and arrangement of such interruptions 9 may vary according to the specific material. It can always be defined individually for the respective material combination of the packaging materials 1 and 2 in conjunction with the existing packaging dimensions or their geometry and is relevant to the function of tearing open.
To produce retention points 9, 9a to 9c, apart from the examples of embodiment shown in Figure 3 in the form of interruptions of the cut, alternative embodiments in the form of mini-sealing points in sealed regions within the unsealed surface 6 are possible, as shown in Figure 5. Such a mini-sealed retention point is shown there at 9a; an embodiment in which a corner is also sealed is shown at 9b;
9c, however, represents a mini-retention point which has been formed by a "nose" in the sealed seam.
For understanding of the function of the peeling of the relatively more elastic packaging material web section 2, attention is drawn to the fact that the punched-out section 7 preferably extends close to one marginal sealed seam 3 and the gripping tab 8 defined thereby is not sealed to the underlying region 6 of the packaging material web section 1 but secured only by retention points 9 (Fig. 3).
A further alternative embodiment comprises, as shown in Figure 4, giving a punched-out portion 7 to the relatively more rigid web 1 so that a gripping tab 8 is formed in this web 1 which, by upward bending and subsequent peeling of the upper web 2 adhering thereto, permits problem-free opening of the packaging 10.
For greater ease of comprehension, it is pointed out that the co-ordination of the two packaging material web sections 1,2 is within the discretion of the person skilled in the art.
The following alternatives are conceivable:
Lower web (1) rigid/flat Upper web (2) flexible/flat;
Lower web (1) rigid/deep drawn Upper web (2) flexible/flat;
Lower web (1) rigid/deep drawn Upper web (2) flexible/deep drawn;
Lower web (2) flexible/flat Upper web (1) rigid/flat;
Lower web (2) flexible/flat Upper web (1) rigid/deep drawn;
Lower web (2) flexible/deep drawn Upper web (1) rigid/deep drawn.
A method for the production of a peelable side-sealed bag of child-proof design according to the invention, in which a packed material is inserted between halves 1,2 of a packaging 10 having sealing edges 9 and a gripping aid 4 and the halves 1,2 are welded together, provides in accordance with the invention that one of the halves 1 is selected from material of comparatively low flexural strength and the other half 2 from a material of, comparatively, significantly greater flexural strength, or vice versa, and that whichever is the material half of greater flexural strength is designed with a line of weakness 5 in the starting region of the gripping aid 4.
According to the invention, use of the peelable side-sealed bag for flat, pressure-sensitive forms of medicinal products and in particular for transdermal therapeutic systems is envisaged.
