Various embodiments described in the present disclosure may be carried out in different ways and variations, and in accordance with a desired application or implementation.
Apparatuses for blistering medicament portions, also known as blister machines, are known, for example, from WO 2013/034504 A1. Depending on the stage of expansion, the apparatuses comprise hundreds of supply and dispensing stations, in each of which a plurality of medicament portions of a certain type of drug are stored. Upon request, individual medicament portions can be dispensed from the supply and dispensing stations and fed to a packaging device via a guiding device, in which the medicament portions are packaged or blistered. Packaging devices for use in the blister machines mentioned above are known, for example, from WO 2016/113291 A1 and WO 2018/184795 A1.
In the case of the packaging apparatuses used in blister machines, blister tubes are usually produced which comprise a plurality of blister bags. To produce the blister bags or blister tubes, a packaging material web is shaped in such a way that one or more medicament portions can be fed to a receiving area. After the medicament portions to be blistered are fed to the receiving area, the individual blister bags of the blister tube are completed by joining together the packaging material web at predetermined locations, the blister bags extending like a strand over the blister tube.
The individual blister bags contain patient-specific medicament portions and/or food supplement portions. A patient is usually provided with a plurality of blister bags or a part of the blister tube, and the patient has to recognize from the intake information printed on a blister bag when the medicament composition contained in a blister bag has to be taken, for example in the morning, at noon, or in the evening. In known packaging apparatuses, the intake information intended for the patient is printed onto the packaging material web before the blister bag is joined together. Because of the small size of the blister bags themselves, the printed intake information for the patient is also kept relatively small, so that it can be difficult or impossible for a patient with a visual impairment to grasp, i.e. read, the information, without the use of certain aids.
It is an object of the present disclosure to provide a packaging apparatus for small piece goods, with which blister bags can be produced, the intake information of which can also be perceived by patients with a visual impairment. It is further an object of the present disclosure to provide a method for producing such blister bags.
The object is achieved on the one hand by a packaging apparatus for small piece goods according to aspects of the disclosure. Within the scope of the present disclosure, the term “small piece goods” is intended in particular to comprise medicament portions and food supplement portions in, for example, tablet form. However, the packaging apparatus can also be used to pack other small piece goods (for example, screws and the like).
The packaging apparatus for small piece goods according to the disclosure, with which blister bags can be produced having intake information perceivable by people with a visual impairment, comprises a packaging material guiding device for receiving an elongated packaging material web, the packaging material guiding device being designed such that the elongated packaging material web is shaped in such a way that it is suitable for receiving medicament portions (i.e. has a receiving area for small piece goods) and continues in a direction of travel. How exactly the elongated packaging material web entering the packaging material guiding device is shaped for receiving small piece goods depends on the manner in which the small piece goods to be packaged are fed, how the direction of travel of the formed packaging material web runs and whether the packaging material web is already pre-shaped, for example. For example, it is conceivable that the packaging material is fed already folded in the longitudinal direction or in the direction of travel.
If, for example, the packaging material web is moved vertically downward after the shaping, as described in WO 2018/184795 A1, the packaging material web is shaped in a tubular manner, the lower end of the tubular part being formed by a separating area into a leading, already formed blister bag. In such a case, the medicament portions (that is, the small piece goods) are routed directly from above into the receiving area formed with the folding and guiding device. If, alternatively, the direction of travel is more oblique, as described in WO 2016/113291 A1, the packaging material web is shaped into a kind of tetrahedron open at the top, which forms the receiving area for the medicament portions. The exact structural design of the packaging material guiding device is not substantial for the disclosure as long as the function described above is fulfilled by it.
The packaging apparatus according to aspects of the disclosure further comprises a longitudinal joining device downstream of the packaging material guiding device, which joins the packaging material web at a packaging material overlap area in the direction of travel of the packaging material web. This packaging material overlap area can be predetermined by a special structural design of the packaging material guiding device.
A transverse joining device is also arranged downstream of the packaging material guiding device and joins the packaging material web together at predetermined intervals (in relation to the longitudinal axis or direction of travel of the packaging material web) transversely to the direction of travel to a transverse joining area, the transverse joining device comprising two joiners, at least one of which can be moved transversely to the direction of travel. This transverse joining area can correspond to the upper separating part between two blister bags. This is the case when the blister tube (as is customary) is produced in such a way that the transverse joining area is assigned to two successive blister bags, between which, for example, a perforation is provided within the transverse joining area to separate the individual blister bags. Alternatively, the blister tube can also be produced in such a way that each blister bag is assigned two “separate” transverse joining areas. The longitudinal joining device and the transverse joining device can be arranged one behind the other in the direction of travel as separate components (the transverse joining device being arranged regularly downstream of the longitudinal joining device), but it is also conceivable that the two joining devices are arranged in a common joining component.
The packaging apparatus also comprises, according to aspects of the disclosure, a plurality of embossers which can be moved individually transversely to the longitudinal direction and an embosser stop area, the embossers and the embosser stop area cooperating in such a way that elevations which are palpable can be formed by the embossers in the transverse joining area.
By forming palpable elevations in the transverse joining area, it is also possible for a patient with a visual impairment to differentiate between a plurality of blister bags. If, for example, three blister bags are provided to a patient per day, it is possible when using two embossing pins to mark the three blister bags with a pattern such that the patient can unequivocally assign them to a time of intake. The packaging device according to the disclosure thus makes it possible to provide blister bags which can also be clearly assigned to a predetermined time of intake by a patient with a visual impairment.
How exactly the embossers are realized in the packaging apparatus is not substantial for the present disclosure, as long as it is ensured that the palpable elevations are introduced into the transverse joining area. For example, it is conceivable to provide a further device downstream of the joining devices, which device comprises the embossers and by which the palpable elevations are introduced into the transverse joining areas. However, in order to avoid the use of a separate device for guiding the embossers, it is provided in one or more embodiments of the packaging apparatus according to the disclosure that the embossers are arranged so that they can be extended and retracted in one of the joiners and that the other joiners have an elastically designed joining surface at least in one contact area or a plurality of embossers receptacles which are individually movable transversely to the direction of travel. In aspects of the disclosure, the palpable elevations are thus generated simultaneously with the production of the transverse joining area, so that it is not necessary to introduce the palpable elevations with a separate device after the transverse joining area has been created, which reduces or keeps low the complexity and the overall length (in the direction of travel) of the packaging apparatus.
Even when two embossers are used, it is possible to clearly identify the blister bags in such a way that a patient can differentiate between four different blister bags, making it possible for a patient with visual impairment to be able to differentiate the blister bags of a daily requirement without help. In order to clearly differentiate a large number of blister bags from one another and to simplify the determination of the information provided by the elevations, it is provided in one or more embodiments of the packaging apparatus according to the disclosure that the embossers are formed of at least one 2 by 3 matrix (horizontal, vertical) of embossing pins so that a dot pattern in the shape of a Braille character can be generated per matrix by the embossing pins. Even if only one matrix is used, 64 different patterns can be displayed, so that in such a case blister bags can be clearly distinguished from one another for a whole week, for example. When using larger and/or a plurality of matrices, it is therefore possible to emboss a large number of data in the transverse joining area.
The blister bags can be joined in different ways from the elongated packaging material web. For example, certain areas can be provided with an adhesive prior to joining. In one or more embodiments, however, it is provided that at least one joining surface of a joiner can be heated, so that the joining together takes place as a welding of the packaging material.
As already indicated above, the packaging material guiding device can be realized differently depending on the overall construction of the packaging apparatus. In one or more embodiments, the packaging material guiding device comprises a central through opening and is designed such that the elongated packaging material web is fed to the through opening, which is realized such that the elongated packaging material web is shaped in the direction of travel to a tubular packaging material web defined by the through opening and having a packaging material web overlap area, wherein a guide part of a guiding device for medicament portions extends within a part of the tubular packaging material web, which ends in the delivery area of the tubular packaging material web. In order to ensure in a tubular-shaped packaging material web that the transverse joining by the transverse joining device without overlapping of the packaging material web takes place without errors in the transverse joining area, it is provided in aspects of the disclosure that a plurality of spreaders are arranged in the lower area of the guide part which spread open the tubular packaging material web for joining by the transverse joining device in accordance with the alignment of the joiners. In other words, the spreaders ensure that the tubular packaging material web is adapted to the alignment of the joiners before being joined, i.e. is converted from the circular shape into an elongated shape, which can be better joined together by the transverse joining device.
The application also relates to the use of a packaging apparatus according to aspects of the disclosure for producing a blister tube comprising a plurality of blister bags.
In the method according to the disclosure for producing a blister tube comprising a plurality of blister bags, an elongated packaging material web is first provided, which is then shaped into a receiving area by a packaging material guiding device for receiving medicament portions. Exactly how this shaping is carried out depends on the exact design of the packaging material guiding device, the direction of travel of the packaging material web and the exact design of the packaging material, as discussed above. After shaping for receiving small piece goods, small piece goods are fed to the receiving area and the packaging material web is joined together to form a tubular packaging material web with a longitudinal joining device in a packaging material overlap area in the direction of travel of the packaging material web, wherein the joining together and feeding of small piece goods can also take place simultaneously or in reverse order. With the transverse joining device, the tubular packaging material web is joined at predetermined intervals, based on the direction of travel or longitudinal axis of the packaging material web, in a transverse joining area, which can also take place simultaneously with the joining in the longitudinal direction. According to the disclosure, a palpable pattern is embossed in the transverse joining area by a plurality of embossers which can be moved transversely to the direction of travel.
In one or more embodiments of the method according to the disclosure, the embossers are designed as at least one 2 by 3 matrix of embossing pins, so that a dot pattern in the shape of a Braille character can be embossed into the transverse joining area per matrix by the embossing pins. In this way, a large amount of information can be introduced by palpable characters that are known to a large number of patients with visual impairments.
In order to support the joining together of the pre-shaped packaging material web with the transverse joining device and to reduce the likelihood of joining errors, it is provided in one or more embodiments of the method that the tubular packaging material web is spread open by a plurality of spreaders before the joining.
In aspects of the disclosure, a specially designed packaging material guiding device is described which is suitable for a not pre-shaped (pre-folded) packaging material web. In the following detailed description, medicament portions are provided as small piece goods.
The embodiment of the packaging apparatus 1 shown comprises a packaging material feed 30, by which the elongated packaging material web 40 is fed to a packaging material guiding device 10 via a plurality of rollers, the path of the packaging material web 40 being shown only partly in
A longitudinal joining device 20 is arranged downstream of the packaging material guiding device 10, with which an overlapping area 41 of the shaped packaging material web 43 extending in the direction of travel is joined, as is described in more detail with reference to the following figures.
Downstream of this longitudinal joining device 20, a transverse joining device 100 is arranged, which comprises two joiners 110, 120, wherein as shown the joiners 120 can be moved transversely or orthogonally to the direction of travel of the packaging material web 40, as already indicated in
The packaging material overlap area 41 is first welded by the welding jaws 24a, 24b shown in
As can be seen in
With regard to a possible design of the packaging material guiding device 10 as well as the medicament guiding device 60 and the longitudinal joining device 20, reference is also made to the application WO 2018/184795 A1, the relevant disclosure content of which is hereby incorporated into this application for the aforementioned devices.
In order that a palpable pattern can be introduced into the transverse joining area 42 by the extendable and retractable embossing pins 112, the embossing pins 112 cooperate with an elastically designed stop area 121 which is formed in the joiners 120.
First, a packaging material web 40 is provided in a step 200, which, in a step 210, is shaped into a receiving area 45 for receiving medicament portions. This is done, for example, with the packaging material guiding device 10 described in the previous figures. After the receiving area 45 has been formed, the medicament portions to be blistered are fed to it in a step 220. In a step 230, the shaped packaging material web 43 is joined (e.g., welded) with the longitudinal joining device 20 at a packaging material overlap area 41 in the direction of travel of the packaging material web 40 to form a tubular packaging material web 43. In a subsequent step 240, the tubular packaging material web 43 is joined at predetermined intervals in or to a transverse joining area 42 with a transverse joining device 100 arranged downstream of the longitudinal joining device 20. When viewed in the direction of travel, this transverse joining area 42 is the end of the blister bag that has just been processed and at the same time the “lower” end of a new subsequent blister bag, the transverse joining area 42 forming a part of the receiving area 45 of the following blister bag. According to aspects of the disclosure, a palpable pattern is embossed in step 250 in the transverse joining area 42 by a plurality of embossers 112 which can be moved transversely to the direction of travel, the arrangement in the transverse joining area 42 being such that the patterns are assigned to one or both blister bags. In one or more embodiments of the apparatus and the method described here, the pattern is only assigned to one blister bag; when using joiners having more complex embossers, patterns for both blister bags can also be embossed in the transverse joining area 42, which “share” the transverse joining area 42 (as the upper or lower end of the blister bags, regularly separated by a perforation made with a separator 130).
