Description

The invention relates to a container for a miscible medical product and / or a miscible nutritional product. The container includes a first flexible film and a second flexible film disposed one upon the other. A product space is defined by respective opposing sides of the first flexible film and the second flexible film and by a circumferential perimeter seam that permanently locally connects the first flexible film and the second flexible film. The product space is divided into at least three product chambers by means of at least two dividing seams, wherein each of the dividing seams temporarily connects the first flexible film and the second flexible film locally and at least in sections.Such containers are known. Due to the fact that the first film and the second film are flexible, such containers are often also referred to as bags.Such containers are used when components of the miscible medical product and / or the miscible nutritional product are to be kept separate from each other during a storage phase. In such a case, each component may be provided in a product chamber. After the product chambers are separated from each other by the at least two dividing seams, mixing of the components is avoided. This may have positive effects on storage. Further, in such a container, the components can be optionally mixed by completely or partially releasing one or more of the dividing seams. This means that in the region of the one or more of the dividing seams, at least in sections, the first flexible film and the second flexible film are no longer locally connected to one another.In this context, the dividing seams can be completely or partially detached, for example, by applying mechanical pressure to one or more of the components provided in an adjacent product chamber. This leads to the adjacent dividing seam becoming detached or broken at least in sections. It is understood that it is important to release only the section or sections of the dividing seam provided for this purpose. The remaining sections and seams, in particular the circumferential seam, should remain closed, i.e. continue to connect the first flexible film and the second flexible film.This means that such a container must be stable on the one hand in the region of the seams. On the other hand, the container must allow the selective detachment of seams and / or suture sections provided for this purpose. This is in contradiction to a certain extent, since a high stability is frequently associated with poor releasability and vice versa.The object of the present invention is therefore to resolve or at least alleviate this contradiction. The aim is therefore to create a container which, on the one hand, makes it possible, owing to stable seams, to reliably keep components of a miscible medical product and / or nutritional product separate from one another. At the same time, this container is intended to allow components of the medical product and / or nutritional product to be mixed in a desired manner.The object is achieved by a container for a miscible medical product and / or a miscible nutritional product. The container includes a first flexible film and a second flexible film disposed one upon the other. A product space is defined by respective opposing sides of the first flexible film and the second flexible film and by a circumferential perimeter seam that permanently locally connects the first flexible film and the second flexible film. The product space is divided into at least three product chambers by means of at least two dividing seams, wherein each of the dividing seams temporarily connects the first flexible film and the second flexible film locally and at least in sections. At least one of the two dividing seams meets the circumferential seam in a connecting zone. The connection zone comprises a reinforcing element which locally connects the first flexible film and the second flexible film. The reinforcing element protrudes by at least 10 mm relative to the circumferential seam. In this connection, the dividing seam that meets the circumferential seam in the connecting zone is at least partially releasable. This means that at least a portion of this dividing seam is provided to selectively release a connection between the first flexible film and the second flexible film, so that components of the medical product and / or of the nutritional product provided in product chambers adjoining this dividing seam can be mixed. In the connection zone, the circumferential seam, which is intended to permanently connect the first and the second film reliably, therefore coincides with the dividing seam, which is intended to be releasable at least in sections. In this connection, the reinforcing element ensures that the permanent connection of the circumferential seam is reliably maintained even in situations in which comparatively large mechanical forces and / or stresses act on the adjacent dividing seam. This may be the case, for example, while the dividing seam is released by mechanically pressurizing a component present in an adjacent product chamber. Thus, undesirable leaks resulting from the undesirable detachment of permanent connections per se are avoided. At the same time, the detachment of the sections of the dividing seam provided for this can be simple. The remaining dividing seams can respectively temporarily connect the first film and the second film permanently or at least in sections. In this context, a temporary connection is understood to mean a releasable connection.Within the scope of the present invention, it has been found that the reinforcing element must protrude by at least 10 mm with respect to the circumferential seam. It is emphasized that when determining a distance by which the reinforcing element protrudes with respect to the circumferential seam, a width of the circumferential seam is ignored. In other words, the width of the circumferential seam is not measured as well. As a result, the container is particularly mechanically stable in the connection zone, in particular more stable than the circumferential seam taken on its own.The reinforcing element also simplifies the production of the container. This is because the reinforcing member locally connects the first flexible film and the second flexible film. The first flexible film and the second flexible film are thus connected to one another over a comparatively large area in the region of the connection zone. This applies in particular in comparison with portions of the circumferential seam which are located outside the connecting zone. This avoids the formation of creases in the first flexible film and / or the second flexible film that otherwise arise or can be applied when the circumferential seam and / or one or more of the dividing seams are produced. In this context, the application of folds means that the container is converted during production into a configuration which subsequently, for example in the filled state of the container, leads to the formation of folds. This can take place in particular during the transport of filled containers on a conveyor belt or during the application of an outer packaging to the container. This is avoided in the present case. In particular, the formation of so-called S / Z folds is avoided. In this connection, folds usually represent undesirable mechanical weak points of the container. In other words, by using the reinforcing element, a mechanical stability with which the first film and the second film are held against one another in the region of a seam can thus be adjusted in a targeted manner. Thus, seam sections can be defined in a targeted manner, which are intended to be released by a user, and other seam sections, which are intended to permanently connect the first film and the second film.The container, i.e. the first flexible film and / or the second flexible film, may be made of a polymer material. Such materials are particularly well suited for the storage and administration of miscible medical products and / or nutritional products. The polymeric material may be multi-layered.Preferably, both the peripheral seam and the dividing seams are welds.In one example, a location where the at least two dividing seams meet is called a crossing point. The container can thus comprise such an intersection point.According to an alternative, the product space is divided into the at least three product chambers by means of at least three dividing seams, wherein each of the dividing seams temporarily connects the first flexible film and the second flexible film locally and at least in sections. The at least three dividing seams may meet at one location. In this context, this location may be called a crossing point. The aforementioned effects and advantages apply equally to containers having at least three dividing seams.According to one variant, the reinforcing element is a planar seam segment. The reinforcing element is therefore formed as a section of a seam, in particular the circumferential seam and / or that dividing seam which meets the circumferential seam in the connection zone. The fact that the seam segment is planar is to be understood here with reference to the remaining sections of the seam as whose seam segment the reinforcing element is formed. A planar seam segment has a surface area in relation to a unit of length which is greater than in the case of a remaining section of the same seam. In other words, the planar seam segment represents a thickened or widened seam segment. The surface area is preferably greater by at least 25%. Such a reinforcing element can be realized comparatively simply and cost-effectively during the production of the container. In addition, such a reinforcing element is comparatively compact, so that a product volume of the container is only insignificantly impaired, or not impaired at all, by the reinforcing element.According to another variant, the reinforcing element is a seam segment projecting convexly in the direction of an interior of the product space. In this connection, a width of the seam segment constituting the reinforcing element can be equal to a width of the remaining segments of the seam. Alternatively, a width of the suture segment constituting the reinforcing element may be greater or smaller than a width of the remaining segments of the suture. The suture segment constituting the reinforcement element is, for example, curved. In this connection, a reinforcing effect is achieved in that the seam segment is formed convexly in the direction of the interior of the product space. This geometry has the effect that when the adjacent dividing seam is released, the reinforcing element is comparatively difficult to release.According to an embodiment, the at least one of the two dividing seams that meets the circumferential seam in the connection zone may temporarily locally connect the first flexible film and the second flexible film. In other words, this dividing seam is designed as a detachable seam. That is, it is configured to release the temporary connection between the first film and the second film if a mechanical force and / or a mechanical stress exceeding a predetermined force and / or stress threshold is applied to the dividing seam.It is also possible for the at least one of the two dividing seams, which meets the circumferential seam in the connecting zone, to run obliquely in a use position of the container. In this context, a position of use of the container refers to an orientation of the container in the space that it assumes when the medical product and / or nutritional product that can be provided in the container is administered to a patient and / or customer. An oblique course means that the dividing seam does not run either horizontally or vertically. In a case in which the container is suspended on a stand in the use position, a vertical direction generally runs from a mechanical interface via which the container is coupled to the stand to an end of the container opposite this mechanical interface, at which an outlet for administering the medical product and / or nutritional product is usually provided. It has been found that by means of such an obliquely extending dividing seam, a comparatively easy releasability of the sections of the dividing seam provided for this purpose can be connected to a high mechanical stability of the remaining seams, in particular of the circumferential seam.The at least one of the two dividing seams, which meets the circumferential seam in the connection zone, can be inclined relative to a horizontal by 0 to 60 degrees, preferably by 15 to 40 degrees. It has been found that by means of such an obliquely extending dividing seam, a comparatively easy releasability of the sections of the dividing seam provided for this purpose can be connected to a high mechanical stability of the remaining seams, in particular of the circumferential seam.In a variant, the at least one of the two dividing seams that meets the circumferential seam in the connection zone is substantially straight or substantially arc-shaped. A chord of the arc-shaped dividing seam extends obliquely. In the case of an arc-shaped seam, a radius of the arc may be 50 mm to 600 mm. Preferably, the radius of the arc is 60 mm to 120 mm. More preferably, the radius of the arc is 70 mm to 90 mm. It has been found that such seams can combine a comparatively simple releasability with a comparatively high stability of further seams.In one embodiment, the at least one of the two dividing seams that meets the circumferential seam in the connection zone at least temporarily separates an uppermost and a lowermost product chamber from one another. In such a configuration, it is of particular importance that the dividing seam is easily releasable and the adjacent circumferential seam is particularly stable. This is achieved by the reinforcing element, so that in such a configuration undesirable leaks are avoided to a particular extent.The reinforcing element can be circular-segment-shaped or polygonal-segment-shaped. For example, the reinforcing element has the shape of a rectangle. Alternatively, the reinforcing element may be trapezoidal. According to a further alternative, the reinforcing element is triangular, quadrangular, pentagonal or hexagonal. It is also possible for the reinforcing element to be shaped as a section of a triangle, quadrilateral, pentagonal or hexagon. According to a further alternative, the reinforcing element is semicircular. Such reinforcing elements can be realized comparatively easily during the production of the container. Moreover, they provide the desired reinforcing effect. At the same time, they are relatively compact, so that they do not influence the product volume of the container or only influence it to a very small extent.The reinforcing element can be three-dimensionally shaped. In this connection, the reinforcing element extends in particular out of a surface defined by the first flexible film and the second flexible film. For example, the reinforcing element is cup-shaped. Such a configuration produces a particularly advantageous combination of an easily detachable dividing seam and a mechanically stable circumferential seam.In one example, a largest dimension of the reinforcing element is at least 20 mm, preferably at least 25 mm. This can be a height or a width of the reinforcing element. It has been found that such a dimension of the reinforcing element represents a good compromise between simple mikroability, high reinforcing effect and compactness.The reinforcing element preferably has an area of at least 200 mm 2, preferably of at least 250 mm 2. More preferably, the area may be at least 500 mm 2. Such a reinforcing element combines a comparatively small space requirement with a high reinforcing effect.The container may comprise a further reinforcing element which is arranged in a further connection zone and projects locally with respect to the circumferential seam. The further reinforcing element has the same effects and advantages which have already been mentioned with regard to the first-mentioned reinforcing element. The examples and variants mentioned in connection with the first-mentioned reinforcing element can also be combined with the further reinforcing element.The product space of the container may have a capacity of at least 500 ml, preferably at least 1000 ml. The product space is thus comparatively large. In order to keep a medical product and / or nutritional product provided in the product space securely within the container and / or in order to separate components of the medical product and / or nutritional product securely from one another, such containers must be mechanically particularly stable. At the same time, at least a portion of a dividing seam must be manually releasable. This is achieved in a particularly advantageous manner by means of the reinforcing element according to the invention.The invention will be explained below with reference to various exemplary embodiments which are shown in the attached drawings. The following are shown: FIG. 1 shows a container according to the invention according to a first embodiment, FIG. 2 shows a container according to the invention according to a second embodiment, FIG. 3 shows a container according to the invention according to a third embodiment, FIG. 4 shows a container according to the invention according to a fourth embodiment, FIG. 5 shows a section of a container according to the invention according to a fifth embodiment, FIG. 6 shows a section of a container according to the invention according to a sixth embodiment, FIG. 7 shows a section of a container according to the invention according to a seventh embodiment, FIG. 8 shows a container according to the invention according to an eighth embodiment, FIG. 9 shows a section of a container according to the invention according to a ninth embodiment, FIG. 10 shows a section of a container according to the invention according to a tenth embodiment, FIG. 11 shows a section of a container according to the invention according to an eleventh embodiment, FIG. 12 shows a section of a container according to the invention according to a twelfth embodiment, FIG. 13 shows a section of a container according to the invention according to a thirteenth embodiment, and FIG. 14 shows a section of a container according to the invention according to a fourteenth embodiment.FIG. 1 shows a container 10 according to a first embodiment. This is designed to receive a miscible nutritional product.The container 10 comprises a first flexible film 12 and a second flexible film 14 which are arranged one on top of the other.Each of the first flexible film 12 and the second flexible film 14 is made of a multilayer polymeric material. The container 10 can therefore also be referred to as a bag.A product space 16 of the container 10 is thus bounded by respective opposite sides of the first flexible film 12 and the second flexible film 14 and by a circumferential circumferential seam 18 that permanently locally connects the first flexible film 12 and the second flexible film 14.In the embodiment shown, the product space 16 has a capacity of about 2500 ml, i.e. that at most 2500 ml of the miscible medical product and / or the miscible nutritional product can be accommodated therein.The container 10 is designed as a multi-chamber container.In the exemplary embodiment shown, the container 10 comprises a total of three product chambers 20 a, 20 b, 20 c.The product chamber 20 ais an uppermost product chamber. It is bounded by a portion of the circumferential seam 18, as well as by a first dividing seam 22 and a second dividing seam 24.The product chamber 20 bis a middle product chamber. It is bounded by a portion of the circumferential seam 18, by the first dividing seam 22, and by a third dividing seam 26.The product chamber 20 cis a lower product chamber. It is bounded by a portion of the circumferential seam 18, by the second dividing seam 24, and by the third dividing seam 26.The container 10 also comprises an outlet interface 28, which is integrated into the circumferential seam 18 and adjoins the product chamber 20 c, i.e. the lower product chamber.The product space 16 is thus divided into three product chambers 20 a, 20 b, 20 cby means of the three dividing seams 22, 24, 26.In the present case, the designations of the product chambers 20 a, 20 b, 20 c relate to a position of use of the container 10.In each of the product compartments 20a, 20b, 20c, a component of the miscible nutritional product may be provided. For example, one of the components is rich in glucose. Another component is lipid rich and another component is amino acid rich.In a storage state of the container 10, each of the first dividing seam 22, the second dividing seam 24, and the third dividing seam 26 locally connects the first flexible film 12 and the second flexible film 14 over their entire lengths. Thus, in the storage state, the components of the miscible nutritional product are separated from each other.If the nutritional product is to be administered to a patient or customer, the components must be mixed.For this purpose, the second dividing seam 24 and the third dividing seam 26 are formed as detachable seams. That is, the connection of the first flexible film 12 and the second flexible film 14 formed by these dividing seams 24, 26 can be released or broken by mechanically acting on the container 10.In this way, the components present in the product chambers 20 a, 20 b, 20 cmay mix.In the present example, the first dividing seam 22 is formed as a permanent seam. This means that this seam is not intended to break the connection between the first flexible film 12 and the second flexible film 14.In the first embodiment, moreover, all the division seams 22, 24, 26 are arc-shaped. A chord of the second dividing seam 24 extends substantially horizontally in the use position of the container 10.The dividing seams 22, 24, 26 furthermore meet at a so-called crossing point 30.The second dividing seam 24 extends from the crossing point 30 to the circumferential seam 18. the second dividing seam 24 separates the product chamber 20 aand the product chamber 20 c, i.e. the uppermost product chamber and the lowermost product chamber.The region in which the second dividing seam 24 meets the circumferential seam 18 represents a connecting zone 32.The connection zone comprises a reinforcing element 34.In the first embodiment, the reinforcing element 34 is designed as a planar seam segment which permanently connects the first flexible film and the second flexible film 14 locally.In the first embodiment, the reinforcing member 34 is also circular-section-shaped. The circular section has a radius R1 at a height of 16 mm.In addition, the reinforcing element 34 merges via radii R 2 into the circumferential seam 18. The radii R2 are 6 mm.In addition, the reinforcing element 34 has a height H which is 30 mm in the example shown.A width B of the reinforcing element 34 is 10 mm in the example shown. In this case, the width B is measured starting from an edge of the circumferential seam 18. The reinforcing element 34 thus protrudes by 10 mm relative to the circumferential seam 18. This takes place in the direction of an interior of the product space 16.Thus, in the first embodiment, the height H of the reinforcing member 34 is the largest dimension thereof.A surface area of the reinforcing element 34 is approximately 250 mm 2. in the embodiment shown.A second embodiment of the container 10 is shown in Fig. 2. In this case, only the differences from the first embodiment will be discussed below.In contrast to the first embodiment, the second dividing seam 24 is straight per se, but extends obliquely in a use position. In the present case, the second dividing seam is inclined by an angle W at a height of approximately 20° with respect to a horizontal.The first dividing seam 22 and the second dividing seam 26 also have a different course in the second embodiment than in the first embodiment.The shape and dimensions of the reinforcing member 34 are as in the first embodiment.A third embodiment of the container 10 is illustrated in FIG. 3. In this case, only the differences from the already explained embodiments will be discussed below. The container 10 of the third embodiment is a development of the container 10 according to the second embodiment.The container 10 of the third embodiment comprises a further reinforcing element 36 which projects with respect to the circumferential seam 18.This is arranged in a further connecting zone 38, wherein in the further connecting zone 38 the third dividing seam 26 meets the circumferential seam 18.The further reinforcing element 36 is also designed as a planar seam section.The shape and dimensions of the further reinforcing element 36 correspond to the reinforcing element 34.FIG. 4 shows a fourth embodiment. Again, only the differences from the above embodiments will be discussed.The fourth embodiment represents in particular a variant of the third embodiment, in which the second dividing seam 24 runs substantially horizontally in a use position of the container 10.A fifth embodiment of the container 10 is shown in Fig. 5. Only a portion of the container 10 can be seen. Again, only the differences from the above embodiments will be discussed.The differences relate to the second dividing seam 24, which in the embodiment according to FIG. 5 is composed of a straight segment and an arcuate segment.A further difference relates to the reinforcing element 34.While the shape thereof corresponds to the aforementioned embodiments, the reinforcing member 34 of the fifth embodiment is larger.The radius R1 is now 20 mm. Moreover, a width of the reinforcing member is 15 mm. The height H is 43 mm.The straight segment of the second dividing seam 24 projects by 25 mm with respect to the reinforcing element 34.A sixth embodiment of the container 10 is shown in Fig. 6. Again, only a portion of the container 10 can be seen. As before, the differences from the above embodiments will be discussed.The container 10 according to the sixth embodiment is a variant of the container 10 according to the fifth embodiment. The reinforcing element 34 of these two embodiments is the same. However, in the sixth embodiment, the second dividing seam 24 is straight as a whole, but inclined by an angle W of 18° with respect to a horizontal.A seventh embodiment of the container 10 is shown in Fig. 7. Again, only a portion of the container 10 can be seen. As before, only the differences from the already explained exemplary embodiments are discussed.The container according to the seventh embodiment is a variant of the container 10 according to the fifth embodiment and the sixth embodiment. The reinforcing member 34 of the seventh embodiment is similar to the reinforcing member 34 of the fifth embodiment and the sixth embodiment.Only the second dividing seam 24 is configured differently. In the seventh embodiment, it is composed of two arc-shaped segments. In this case, chords of these two arcuate segments run obliquely at an angle W to the horizontal.Further, the arcuate segment disposed adjacent the reinforcing member 34 projects about 30 mm from the reinforcing member.FIG. 8 shows an eighth embodiment of the container 10.The eighth embodiment of the container 10 is in particular a variant of the container 10 according to the first embodiment. The eighth embodiment differs only in a modified reinforcing element 34.The reinforcing element 34 is polygonal, more precisely rectangular, in the eighth embodiment.In this case, the corners of the rectangle which project with respect to the circumferential seam 18 are rounded off with a radius R 3 which, in the embodiment shown, is 4 mm.In addition, the reinforcing element merges again via a radius R 2 into the circumferential seam 18. The radius R2 is 6 mm.The width B of the reinforcing element 34 is again 10 mm. The height of the reinforcing member 34 according to the eighth embodiment is 30 mm.Referring now to Fig. 9, there is shown a ninth embodiment of the container 10. Only a portion of the container 10 can be seen. Again, only the differences from the above embodiments will be discussed. The container according to the ninth embodiment is in particular a variant of the container according to the eighth embodiment.Here, the reinforcing member 34 of the container 10 according to the ninth embodiment and the container 10 of the eighth embodiment are the same in shape and size.The container 10 according to the ninth embodiment is different from the container 10 according to the eighth embodiment only in the shape of the second dividing seam 34.In the ninth embodiment, the second dividing seam 34 is straight per se and extends horizontally in a use position of the container 10.A tenth embodiment of the container 10 is shown in Fig. 10. Only a portion of the container 10 can be seen. Again, only the differences from the above embodiments will be discussed.The differences relate to the second dividing seam 24, which in the embodiment according to FIG. 10 is composed of a straight segment and an arcuate segment.A further difference relates to the reinforcing element 34.While the shape thereof corresponds to the shape of the reinforcing members 34 of the eighth and ninth embodiments, the reinforcing member 34 of the tenth embodiment is larger.The width B is 12 mm and the height H is 32 mm. The corners are rounded with a radius R3 at a height of 7 mm.An eleventh embodiment of the container 10 is shown in FIG. 11. Again, only a portion of the container 10 can be seen. As before, the differences from the above embodiments will be discussed.The container 10 according to the eleventh embodiment is a variant of the container 10 according to the tenth embodiment. The reinforcing element 34 of these two embodiments is the same. However, in the eleventh embodiment, the second division seam 24 is composed of two arc-shaped segments. In this case, chords of the arcuate segments run at an angle W obliquely to the horizontal.The arcuate segment, which is arranged adjacent to the reinforcing element 34, projects by about 33 mm relative to the reinforcing element 34.A container 10 according to a twelfth embodiment is shown in FIG. 12. Only a portion of the container 10 can be seen. Again, only the differences from the already explained embodiments are mentioned.The container according to the twelfth embodiment represents a variant of the container according to the ninth embodiment.However, in the twelfth embodiment, the reinforcing element 34 is no longer embodied as a full-area connection between the first flexible film 12 and the second flexible film 14. Rather, in the twelfth embodiment, the reinforcing member 34 has a V-shaped line portion along which the first flexible film 12 and the second flexible film 14 are not joined. In addition, the circumferential seam 18 is interrupted in the region of a tip of the V-shaped line section.The outer dimensions of the reinforcing element 34 according to the twelfth embodiment correspond to the outer dimensions of the reinforcing element 34 according to the ninth embodiment.A container according to a thirteenth embodiment is shown in Fig. 13. Only a portion of the container 10 can be seen. Again, only the differences from the already explained embodiments are mentioned.The container 10 according to the thirteenth embodiment is a variant of the container according to the twelfth embodiment. The difference is that the V-shaped line portion along which the first flexible film 12 and the second flexible film 14 are not joined has an increased width BL. This is 1 mm in the thirteenth embodiment.FIG. 14 shows a fourteenth embodiment of the container 10, which can be regarded as a variant of the first embodiment and the eighth embodiment.In contrast to these embodiments, the reinforcing element 34 in the fourteenth embodiment is formed by a seam segment 40 projecting convexly in the direction of an interior of the product space 16.The suture segment 40 is offset substantially parallel to the circumferential suture 18. A height H of the seam segment is about 82 mm.A width B of the suture segment 40 is 10 mm.In addition, the seam segment 40 merges via radii R 2 at a height of 5 mm on both sides into the circumferential seam 18. Furthermore, the corners of the seam segment 40 resulting from the parallel displacement are rounded with a radius R3 at the height of 10 mm.Even if the reinforcing elements 34, 36 have been presented as two-dimensional, planar elements in the above exemplary embodiments, it is conceivable to alternatively shape each of the reinforcing elements 34, 36 of the aforementioned embodiments three-dimensionally. Reinforcement elements 34, 36 shaped in this way would then have an extension component that protrudes into the plane of the drawing or out of the plane of the drawing.
