[0028] The invention relates to a medication packaging systema medication systemfor providing medicines in liquid, solid or paste form, for example, drugs that exist in the form of powder, drops, tablets, capsules, creams, liquids, and the like. The use of the medication system according to the invention for providing drugs dispensed for each patient individually is particularly advantageous, both in in-patient facilities, such as nursing homes, homes for the elderly, out-patient care services and the like, but also in the private sector. It is primarily the nursing staff and patients in inpatient facilities, but also pharmacies who perform the dispensing who will benefit from the medication system according to the invention.

[0029] The main components, or essential parts of the medication system according to the invention, are a medication tray 1 and a plurality of identically designed containers 2, in which the medicines are packed in the appropriate dosage matched to the time of administration. As shown in particular in FIG. 8, each container 2 consists of a cup 3 and a lid 4, which in a preferred embodiment is implemented as a resealable lid. The cup 3 has a preferably round, in particular cylindrical base 3a and joined to this, a diameter which increases in the direction of its upper rim. The cup 3 consists of a preferably transparent plastic material and has, for example, a fluid holding capacity of preferably 10 ml or 15 ml, but up to a maximum of approximately 45 ml. The lid 4 has a lid edge 5 surrounding the upper rim of the cup 3 and matched to the contour of this rim, which is a separate part from the cup 3 and is connected to the upper rim of the cup 3 in a liquid-tight, but detachable manner. The lid edge 5 externally overhangs the upper rim of the cup 3 and has, for example, a 2 mm to 4 mm wide, flat surface. In the finished condition ready for delivery and use, at least one liquid or solid medicine is located in the container 2, wherein a preferably transparent covering film 6, spanning the edge of the lid 5 and closing off the cup 3, is sealed in particular by gluing or welding, to the surface of the lid edge 5, as will be described in detail below, so that the medicines are provided in containers 2 fitted with a detachable and re-attachable lid 4.

[0030] The container 2 consisting of cup 3 and lid edge 5 is produced in a two-component injection moulding process, wherein an assembly 7 is produced consisting of a number of cups 3, for example seven cups 3 as shown for example in FIG. 5, each with lid edge 5 but still without the covering film 6. The individual cups 3 of an assembly 7 are connected to each other at the lid edges 5 via local connections 8. As shown, for example, in FIG. 5, these connections 8 can be thin points, such as webs, between the lid edges 5 of adjacent cups 3. Other embodiments, for example as thin skins, are also possible.

[0031] In plan view, the tray 1 manufactured from plastic by injection moulding, is substantially rectangularly designed, its length is tailored to the number of containers 2 per assembly 7 and its width to the number of assemblies 7. The tray 1 in the figures shown is provided for holding four assemblies 7 each consisting of seven containers 2. Fewer than or more than four assemblies, for example six assemblies 7, are also possible. The tray 1 has a flat tray sheet 9 with receiving sites 10 for the individual containers 2 of the assemblies 7. The receiving sites 10 in the embodiment shown are openings in the tray sheet 9, the contours of which are matched to the design or configuration and contour of the cup 3 at its upper rim region. The receiving sites 10 are each surrounded by a low elevated portion 11, which is matched to the outer contour of the lid edges 5, so that with the cups 3 inserted the surfaces of the lid edges 5 extend in a single plane, which is located either slightly above the plane of the tray sheet 9, by approximately 0.5 mm, or else in the plane of the tray sheet 9. At the inner edge region of the receiving sites 10, two protrusions 12 are formed diametrically opposite each other, below which protrusions 2a snap into place on the cup wall when the cups 3 are inserted, so that the containers 2 in the tray 1 are secured against accidental loss, but can still be removed from the tray 1 without the exertion of any special effort. Also, due to the projections 2a, 12 snapping into place when the film mesh 17a is removed (FIG. 7), as described below, the cups 3 are secured in the receiving sites 10 and held in position.

[0032] On the two longer sides and on one of the end faces, the tray sheet 9 is surrounded by an edge part 13, on which the tray 1 stands when stored horizontally. The transition regions of the tray sheet 9 to the edge part 13 are rounded. The height of the edge part 13 is such that the cups 3 positioned in the tray 1 remain inside the edge part 13, and on the underside of the tray 1 a plate-shaped receptacle 14 (FIG. 3, FIG. 4) which can be folded open and closed, is surrounded by the edge part 13 in the folded-out condition.

[0033] On the second end face of the tray sheet 9 a front part 15 inclined towards the tray sheet 9 is formed, which provides panels 15a for the individual labelling of the tray 1, for example with patient information. The panels 15a, preferably implemented as shallow depressions, can be provided with adhesive or insertable and removable labels, wherein inserted labels are held by means of retaining tabs 15b. FIG. 4 shows the fold-out receptacle 14, which is connected to the inner side of the edge part 13 in a hinge-like manner in the region of the end of the tray 1 opposite the front part 15. In the embodiment shown in the figures, the receptacle 14 is essentially implemented as a rectangular sheet provided with a number of openingscorresponding to the number of containers that can be positioned in the tray 1. By means of snap-fit connections 16, the receptacle 14, preferably near the front part 15, can be snapped into place on the inner side of the edge part 13. The snap-fit connections 16 in the embodiment shown are projections 16a formed on the rim of the receptacle 14, which detachably clip into appropriately designed openings 16b that are formed on the inner side of the edge part 13 of the tray 1. The receptacle 14 is also provided with a low border 14a facing the inner side of the tray 1, so that a leaflet containing further useful and necessary information regarding the administration of the medication can be placed in the receptacle 14 such that it is secured against loss.

[0034] In the following, the steps up to the preparation of the state of the delivery-ready condition of the medication tray will now be described by reference to FIGS. 5 to 7. As FIG. 5 shows, the assemblies 7 are firstly inserted into the receiving sites 10 of the tray sheet 9 of the tray 1. The individual containers 2 are then filled with medication in accordance with the prescribed medication for the patient. In the next step the containers 2 are sealed with a plastic film 17. The film 17 consists in particular of a single-ply or multi-ply composite made of PE, PP or PET, has a printable top face, and its underside can be used as a sealing layer for the liquid-tight sealing of the cups 3 by gluing or welding. The film 17 is initially located on a backing paper, and is provided with a number of perforations 18 in accordance with the shape of the outer contours of the containers 2 and/or the lid edges 5, for example a number of slits formed by punching. In FIG. 6a the slits are shown as solid lines. As FIG. 6a shows, between adjacent containers 2 of an assembly 7 the perforation is also a slit 18a. The outer dimensions of the film 17 substantially correspond to the outer dimensions of the tray sheet 9. In the surface regions inside the perforations 18 the sealing film 17 has already been printed with information concerning the contents of the containers 2. After the backing paper has been peeled off the film 17, the film is then placed onto the tray sheet 9. In doing so, the film 17 is placed in between positioning tabs 9a formed on the longitudinal edges of the sheet 9.

[0035] In a cold- or hot-sealing device, which can be a welding unit or an adhesive device, which is not the subject of the invention, the film 17 is then sealed to the surfaces of the lid edges 5 within the perforations 18, in particular, thermally welded or glued, wherein gluing can also be hot-melt bonding, contact bonding, reactive bonding, etc. At the same time as the sealing process, a separation of the containers 2 or their lid edges 5 is carried out by cutting the connections 8, preferably by thermal or mechanical means. In the next step (FIG. 7), the film mesh 17a, that part of the film 17 which was not sealed, is torn off along the perforations 18. The containers 2, now each sealed in a liquid-tight manner to the covering film 6, are held in the tray 1 by the protrusions 12 when the unsealed film mesh 17a is torn off. The tray 1 is now in the delivery-ready condition.

[0036] The trays 1 are designed in such a way that they can be stacked on top of one another with and without container 2 to save space. Since the trays 1 are produced from plastic by injection moulding, they are easily cleanable, preferably in dishwashers, and can be disinfected using commercially available disinfectants.

[0037] The containers 2 are removed from the tray 1 individually at the scheduled medication time, wherein to remove the drugs the lid 4 is opened and replaced on the cup 3 if required.

[0038] In a further embodiment, not shown, the cups 3 can be produced integrally with an edge part, which has a surface for welding on the foil 17. In this case, the containers can no longer be closed after the removal of the film.
