Description

  The present invention is a blister film container that cannot be extruded, and has a base film and a cover film to form a receiving chamber for the filling, particularly for the active substance formulation, It relates to a film container of the type connected to the opening area (6) for removal.

  Film containers, so-called blisters, are used inter alia to protect active substance preparations from the effects of the external environment, which can adversely affect the pharmaceutical quality of the active substance preparations. The film container is generally composed of a cover film and a base film, and a space for filling is provided in the base film. The cover film and the base film may be composed of one or more layers of the same or different materials. The cover film is hermetically attached to the base film, for example by gluing, welding or sealing. The cover film and / or the base film is generally in the form of a metal and / or plastic and / or paper film. These materials may exist in a plurality of layers. Typical metal films include, for example, aluminum films and composite aluminum films made of, for example, aluminum and plastic. Materials used for plastic films are polyvinyl chloride (PVC), cyclo-olefin-copolymer (COC), polychlorotrifluoroethylene (PCFE), polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), polycarbonate (PC), polyester (UP), polyacrylate, polyamide (PA) or another plastic or trade name Aclar (registered trademark), for example, registered in particular by Honeywell International, Inc., for example. ) Or a combination of polychlorotrifluoroethylene (PCTFE) and polyvinyl chloride (PVC) or a combination of polyvinyl chloride (PVC) and polyvinylidene chloride (PVdC). It may be multi-layer composite plastic film consisting allowed. Often, film containers or blisters have an aluminum cover film that seals the base film to accommodate the pharmaceutical product or active substance. The thermoformed base film may also have an aluminum foil to prevent water from entering the cavity for holding the pharmaceutical product. To make another diffusion barrier or increase the mechanical stability of the blister, the base film aluminum foil or cover film may optionally be coated on one or both sides with additional plastic and / or paper film. .

  In some countries, regulations regarding child proof packaging of pharmaceutical products are considered or already existed to make it difficult for children to take out the drug.

  The object of the present invention is to provide a film container of the kind described above which has a high child-proof property.

  According to the invention, this problem is solved by the fact that the opening area of the receiving chamber is protected by at least one film section removable from the film container at least for each section.

  As a result of this solution, it is first necessary to pull the foil part away from the foil container at least far enough to allow access to the opening area, so that the filling, in particular the Tablets or capsules can be removed from the receiving chamber. This initial removal of the foil section removes the filling from the receiving chamber, which cannot be easily performed, especially for small children who may be particularly unhealthy by taking medications that are not suitable for small children. , Because the method of opening the receiving chamber is quirky and thereby difficult for children). On the other hand, an adult can easily grasp the receiving chamber and perform the process of opening it. The foil section does not have to be completely removable in every case, exposes the opening area or opening aid, allows the next access to the opening area of the individual film container, and accepts the corresponding It can always be torn or pulled away enough to open the chamber and remove the contents. Obviously, the individual components of the film container, ie its base film and cover film, are so stable in structure that they cannot be easily teared open.

  In order to make it more difficult for an unauthorized person to open the receiving chamber, two film portions that can be at least partially removed one after another from the film container are provided to protect the opening area. Is advantageous.

  According to another feature, the first film section is preferably arranged at the peripheral portion of the angular film container, and the second film section opens into the first film section. It is therefore understood that in order to access the perforations of the second film section, the first film section must first be removed so that the second film section can be removed from the film packaging. Easy to see.

  In order to be able to remove the first film section from the film container relatively easily, the first film section has a triangular structure and forms a corner portion of the first container. The film section is connected to the film container by a perforation extending to at least one outer edge of the film container. Within the scope of the present invention, the term “perforation” refers to actual perforations that penetrate the blister material or actual perforations that penetrate multiple layers or plies of blister material and material thinning, bending lines, folding. It means both lines and embossed marks. This type of perforation can be machined during the manufacture of film packs, whereby individual film containers or parts thereof can be torn or separated.

  The corners forming the first film section may be bent, for example before cutting, to facilitate separation. Separation is performed starting from the outer edge of the film container where the perforation begins. With perforations that terminate at the outer edge, the separation of the film sections can be carried out relatively easily with a kind of peeling action.

  In order to ensure the desired sequence of cutting of the two film sections, the second film section is formed by perforations starting from the perforations of the first film section and extending beyond the opening area to at least about the outer edge of the film container. Connected to the container. Thus, the perforation end associated with the second film section is accessible only after the first film section has been cut away, and the second film section is separated from the first container by a kind of peeling action and opened. The area can be exposed. Obviously, it is not absolutely essential to completely cut the first or second film section from the first container. It is only necessary to remove the first film section until the perforation of the second film section is exposed, and the second film section must be removed until the opening area is reached.

  Conveniently, the blister card has a plurality of film containers that can be separated into segments. Film containers typically have a rectangular base or bottom and are combined to form a rectangular blister card. The individual film containers can be easily separated from the other film containers of the blister card by means of a cross-shaped perforation provided between the individual film containers. Of course, if the base region is substantially triangular, the film container can also form a closed circle or polygon.

  In order to provide another safety measure to avoid removal of the product contained in the film container, particularly without permission from the child, advantageously to separate the first film section The film container needs to be removed from the blister card. In one embodiment, the removable first film section faces the center of the blister card and the film container is preferably of a rectangular structure. Therefore, in order to gain access to the first film section, the first container must first be separated, and the second film section can be cut only after the first film section is removed, An open area can then be reached which must be opened in a separate step in order to remove the filling contained in the receiving chamber of the film container.

  Conveniently, the opening area is embodied as a gripping tab for taking up the cover film, or has a notch or cut as a weakening means of the base film and / or the cover film. Thus, the opening area consists of a tear or tear / punch opening known in the prior art.

  To facilitate operation in providing a relatively wide contact surface, the grip tab advantageously extends with its longitudinal sides parallel to the perforations of the second film section. Once the second film section is separated from the film container, the entire perforation length can be used as a free edge of a grip tab that is easy to grip with a finger.

  In the tear area tear-off variant, the notch or cut begins perpendicularly and centrally from the perforation of the second film section and extends in the direction of the receiving chamber. After cutting the second film section, the film container is opened by tearing along the notch.

  In the film container of the present invention, the base film is made of plastic, aluminum, or a combination of these materials. The size and number of each cavity in the receiving chamber of the base film is determined according to the filling material to be placed therein, such as tablets. Of course, a single blister card may have a plurality of film containers, which have a corresponding number of receiving chambers. The base film is made, for example, of a layer of polyvinyl chloride (PVC) with a thickness or side facing the filling material of about 60 μm and then with an aluminum film with a thickness of approximately 45 μm. Attached to a 25 μm oriented polyamide (oPA) film.

  Advantageously, the cover film consists, for example, of an aluminum film with a thickness of approximately 20 μm attached to a film of polyethylene terephthalate (PET) whose thickness or side facing the filling is approximately 23 μm. Obviously, the base film and the cover film may be the same or made of other materials.

  It will be appreciated that the features described above and the features to be described below can be used not only in the specific combinations specified, but also in other combinations.

  The scope of the present invention is defined based on the description of the scope of claims.

  In the following, the invention will be described in detail by means of a number of exemplary embodiments with reference to the accompanying drawings.

It is a top view of the blister card provided with the film container of the present invention. It is an enlarged view of the film container shown by the detail II of FIG. It is an enlarged view of the film container shown by the detail II of FIG. 1 as 1st deformation | transformation embodiment. It is an enlarged view of the film container shown by the detail II of FIG. 1 as 2nd deformation | transformation embodiment.

  A blister card 2 having a plurality of film containers 1 embodied as a blister has a base film and a cover film with a void 3, which is preferably suitable for a base film using a heat seal lacquer. Are attached in such a way that each forms a closed receiving chamber 4 in the vicinity of the cavity 3 for containing at least one filling, in particular an active substance preparation. The receiving chamber 4 is in this case elongated and rounded, but obviously it can be of any suitable shape. The individual film containers 1 can be separated along the cross perforations 5 according to FIG. 1, ie they can be removed from the blister card 2 according to FIGS. It has a substantially rectangular base or bottom. In particular, in order to make it difficult for the child to remove the filling from the receiving chamber 4 of the film container 1, the opening area 6 associated with the receiving chamber 4 is protected by two film sections 7, 8, which are The first film section 7 that can be separated from the film container 1 at least one after the other and to be separated first is directed towards the center of the blister card 2 and therefore the first film section 7 is removed. In order to do this, the first container 1 must first be removed from the blister card 2.

  The first film section 7 is arranged in the edge region of the film container 1 and has a triangular shape. A first film section 7 forming one corner of the film container 1 is connected to the film container 1 by a perforation 10 extending from one outer edge 9 to another outer edge 9 of the film container 1, while the first An outer edge 9 between which the perforations 10 of the film section 7 extend is defined by the perforations 5 of the blister card 2 and is formed after the film container 1 is separated.

  The perforation 11 of the second film section 8 starts from the perforation 10 of the first film section 7 so that this perforation 11 can only be accessed after the first film section 7 has been at least partially removed. Has been placed. The perforations 11 of the second film section 8 are notably out of the outer edge 9 of the first film container 1 to prevent the second film section 8 from being removed before cutting the first film section 7. It does not extend to one of these. After at least partial removal of the second film section, the opening area 6 can be accessed.

  According to FIGS. 2 and 3, the opening area 6 extends as a means for weakening the base film and cover file, extending vertically and centrally away from the perforation 11 of the second film section 8 and receiving chamber. It has a cut 12 extending in the direction of 4.

  In the variant embodiment of FIG. 4, the opening area 6 is embodied as a gripping tab 13 that pulls the cover film away from the base film, the longitudinal side 14 of which is the perforation of the second film section 8. 11 extends in parallel.

  In order to be able to remove the filling from the receiving chamber 4 of the film container 1, the film container 1 must first be separated from the blister card 2 along the cross perforations 5. The first film section 7 is then cut along the perforation 10 associated therewith from the film container 1 to a location where the perforation 11 associated with the second film section 8 is accessible. The second film section 8 is then taken off by a kind of peeling action until at least the opening area 6 associated with the receiving chamber 4 is exposed. If the opening area 6 is formed by the gripping tabs 13, the second film section 8 should be cut off to the outer edge, preferably completely, if possible. Finally, the film container 1 can be opened by either tearing along the cut 12 or separating the cover film and the base film by the tear tab 13 and the filling can be removed from the receiving chamber 4. Overall, it is possible to open the film container 1 in four steps to be carried out one after the other, which are quirky, so that the child has access to the contents of the receiving chamber 4. Making it more difficult to do.

  In the variant embodiment of FIG. 5, the film container 1 is round and the perforation 10 of the first film section 7 extends in the peripheral region of the film container 1. As described above, the second film section 8 and the perforation 11 are accessible after the first film section 7 is removed, in which case the unsealed area 6 embodied as a cut 12 is in the second area. It can be reached after the film section 8 has been cut. Thus, the round film container 1 can be opened in three stages to be carried out in succession, these three steps are also unusual and allow the child to access the contents of the receiving chamber 4. Make it more difficult.
