Description

Technical Field

[0001] The present invention relates to a container for containing enteral nutrient solution. Background Art

[0002] For a container for containing enteral nutrient solution, which is usually constructed as a bottle, it is generally desired that the container can be reliably supported on the one hand and on the other hand the container can be used to simply release the enteral nutrient solution contained therein.

[0003] A bottle is known from US 5,123,554 A, which is provided for filling with a heat-sensitive nutrient solution. Here, this bottle has a hanging device, which is formed on the lower side of the bottom of the bottle. The hanging device extends in a diagonal direction almost over the entire width of the bottle here, and requires a correspondingly expensive construction of the bottle bottom. Therefore, in order to achieve good force transmission between the hanging device to which the bottle can be fixed and the bottle itself, the construction of the hanging device should obviously be chosen to be relatively wide. However, in practice, it has been shown in such hanging devices that the hanging device must be constructed very stably despite its relatively large width to prevent accidental tearing. When such a hanging device is accidentally torn on one side, the hanging device is easily torn over its entire width. Since the hanging device extends over almost the entire bottom of the bottle, accidental tearing can easily occur. Since there are multiple application points for the corresponding forces with such a wide construction, accidental tearing of the hanging device can occur at these application points. In addition, such a constructed hanging part may affect the standing stability of the bottle, for example when standing on a table. A bottle with a movable hanging part, as well as a device and a method for manufacturing this bottle, are described in WO 2014 / 143415 A1.

[0004] A container for medical liquids is described in US 3,581,928, which has a hanging part on its bottom. In order to be able to stand the container on a flat surface, the hanging part is transferred to a position in which the hanging part engages behind an attachment arranged on the bottom of the container and is snap-fixed.

[0005] An alternative design of the bottom of a bottle for containing enteral nutrient solution is known from WO 2014 / 078404 A1, in which the aforementioned problems do not occur. Therefore, in the case of this bottle, an expensive bottom construction with large-volume cuts is provided to form a hanging device between the non-cut parts of the bottom. This hanging device is supported in a non-movable manner, which involves limitations in terms of the operating comfort of the bottle. In addition, the expensive bottom construction requires a greater material thickness in the bottom area and a more expensive manufacturing method for the entire bottle. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a container for accommodating an enteral nutrition solution, in which the disadvantages known from the prior art are overcome. In particular, the container should be provided so that it can be simply fixed "upside down" on a hook with a suspension device, but can also be positioned on a placement surface such as a table. In particular, the suspension device should be designed to be more stable in practical use than the solutions known from the prior art, but at the same time be less expensive and can be manufactured using less material. In addition, the handling of the suspension device is improved.

[0007] Such a container has an opening, through which an enteral nutrition solution, which can also be called an enteral nutrition solution, can be introduced into the container or drawn out from the container. In addition, the container has a bottom, which is opposite to the opening in the longitudinal extension direction of the container, and which is used to place the container upright on a foundation. If the container is therefore standing on the bottom, the opening of the container points upward with its back to the bottom. The container also has a suspension element arranged on the lower side of the bottom, which can be in two positions. In the first position, the suspension element extends substantially along the bottom of the container, for example, parallel to the plane defined by the bottom and extends along the outside of the bottom. In the second position, the suspension element is angled with the plane defined by the bottom, for example, perpendicular to the plane.

[0008] If the suspension element is in its first position, the container can be in a filling state or storage state, in which the container can be filled or stored. For this purpose, the container can be used in particular standing on its bottom. When the suspension element is in its first position, the container can also be used as a drinking container, such as a drinking bottle. When the suspension element is in its second position, the container can be suspended on a suspension device, such as a hook or a rack, so that the opening of the container points downwards. In this case, in particular in combination with a connected guide system, it can be referred to as an access state or a use state of the container.

[0009] In addition, the container has a hinge device, which connects the suspension element to the lower side of the container at its first end. The hinge device is used to be able to switch the suspension element from a first position to a second position and from the second position to the first position. That is, the suspension element can be flipped from one position to another position by the hinge device. It is recommended and considered here that a repeated change of the state of the container can be achieved by changing the position of the suspension element. Therefore, the container can, for example, first be in its filled state and then switch to its use state. As long as not all of the enteral nutrition solution present in the container is used, the container can then be switched to its storage state again, that is, by switching the suspension element from the second position to the first position. Subsequently, the suspension element can be switched from the first position to the second position again, and thus the container is switched from the storage state to the use state.

[0010] According to the present invention, the container is characterized in that a receiving area for a hanging element is constructed inside the bottom, and the hanging element can be detachably fixed in the receiving area by a connecting device in a first position. Thereby, the hanging element can be reliably positioned in the receiving area. By purposefully loosening or opening the connecting device, the hanging element is converted from its first position to its second position. For example, the tilting position of the container caused by accidentally angled protruding hanging elements can be substantially avoided. Preferably, the receiving area for the hanging piece is constructed as a depression inside the bottom of the container. According to the present invention or preferably, the hanging element is not rigidly fixed in the first position, but is fixed in a manner that it can move within the first position. According to the present invention or preferably, the free second end of the hanging element is arranged movably or displaceably from top to bottom within the first position. Thereby, in particular, the release of the hanging element from its first position is achieved, because it facilitates manual intervention, for example, between the hanging piece and the bottom of the container or the bottom of the receiving area, by fingertips and / or fingernails.

[0011] In a supplementary or alternative design according to the present invention, the container is characterized in that the hinge device extends only in the width direction of the hanging element, and the width direction corresponds to the width of the second end of the hanging element, and the second end is opposed to the first end of the hanging element in the longitudinal extension direction of the hanging element. "Width" is hereby defined as the extension in a direction extending transversely to the longitudinal extension direction of the hanging element. Within the scope of the invention claimed herein, if the two widths deviate from each other, in particular, by up to 50%, in particular, by up to 30% with respect to the maximum width, then the two widths (or two lengths or two other segments) correspond to each other. In an alternative or supplementary design of the present invention, the hinge device extends over a width that is smaller than the width of the second end of the hanging element. In a variant, two corresponding widths, lengths or segments are also identical or substantially identical to each other.

[0012] With this hinge device that is dimensionally matched to the second end of the hanging device and has a reduced width compared to the prior art, on the one hand, less material is required to manufacture the hinge device; on the other hand, the space occupation requirement of the hinge device in its first position is significantly reduced. This results in greater freedom in constructing the bottom of the container. In addition, there are fewer force application points for forces that may tear or otherwise damage the hinge device. Finally, the force transmission to the hinge device is also improved when, for example, applying force with a finger on the second end of the hanging device to the hanging device.

[0013] In contrast, in the case of a hinge device known from the prior art, the introduction of force in this region which extends to the maximum width away from the second end of the suspension device is disadvantageous. Here, it is often necessary to work with a greater force in the region of the second end of the suspension device in order to effect a conversion of the suspension device from one position to another. This can lead to undesired damage to the hinge device.

[0014] Compared with a solution which is also known from the prior art and in which no hinge device is even provided but the suspension device is used permanently, the advantage obtained in an embodiment according to the invention is that the bottom of the container can be manufactured far more inexpensively and with a lower material thickness. This facilitates the manufacturing process of the corresponding container and reduces the manufacturing costs.

[0015] Furthermore, when the suspension element is reliably positioned or fixed in the receiving region by means of the connecting device, an accidental introduction of force into the suspension element can be significantly reduced.

[0016] The connecting device according to the invention is a releasable connecting device. Preferably, the suspension element can be repeatedly fixed to a first position of the suspension element and released again from the first position by means of the connecting device. The suspension element can here be repeatedly converted from the first position to a second position and vice versa. In a variant according to the invention, the connecting device is provided by means of a snap connection. The snap connection is a connection method which is simple to manufacture.

[0017] In order to provide a connecting device, in particular a snap connection, in one embodiment, the suspension element has at least one projection in the region of the second end of the suspension element, which projection is provided and designed to engage behind a structure of the receiving region in order to fix the suspension element in the first position. The at least one projection is used to engage preferably in a rearwardly engaging manner behind a structure of the bottom, in particular a structure of the receiving region, in order to fix the suspension element in the first position. For example, the projection can be provided and designed to snap into a corresponding structure of the bottom. The upright safety of the container is ensured when the suspension element is fixed in the first position. At the same time, the release of the suspension element can be effected by applying a force which is greater than or equal to the holding force of the suspension element in the first position, such that the suspension element can then be converted into the second position when the container is to be converted into its use state. Preferably, the structure is provided in the receiving region by means of at least one lateral depression.

[0018] As described above, the suspension element is not rigidly fixed in the first position, but is fixed in a manner that allows movement within the first position. The free second end of the suspension element is fixed in the first position in a manner that allows movement from top to bottom. Thereby, it is particularly convenient to detach the suspension element from its first position, as manual intervention, for example by fingertips and / or fingernails, between the suspension and the bottom of the container is enabled or at least facilitated. In one embodiment, the mobility of the suspension element is thereby facilitated or at least supported such that the hinge is arranged on a base that provides a transition to the bottom of the container. Preferably, the base has a ridge on the side opposite to the bottom of the container, and the hinge is placed on this ridge. Thereby, the mobility in the first position can be supported. Alternatively or additionally, the mobility of the suspension element is also facilitated such that the thickness of the free second end of the suspension element, in particular the thickness of the suspension element, is chosen to be less than the height of the receiving area for the suspension. By the chosen shape and / or dimensions, a gap is provided between the suspension and the receiving area in the first position of the suspension. In particular, the suspension can thereby be easily detached from its first position and placed back in this first position.

[0019] Another embodiment is characterized in that a narrowing or constriction is formed between the free second end of the suspension element and the hinge. The narrowing provides a gripping area, for example in the form of an area for the index finger and thumb, and can support the suspension of the container. Preferably, the narrowing is at least partially formed as a recess. This enables an inwardly directed bulge and in particular an ergonomic gripping of the suspension using the fingers.

[0020] Preferably, the receiving area for the suspension element has a height that decreases from the outside towards the longitudinal axis of the container. Thereby, on the one hand, the length of the suspension element can be increased and thus the operability in the second position of the suspension element can be improved; on the other hand, the suspension element can be more reliably supported within the receiving area in its first position without lateral protrusion. Preferably, the receiving area is formed by at least three parts starting from the hinge, in particular from the base, namely an internal first part that transitions to an intermediate second part through an internal first crease. This intermediate second part in turn transitions to an external third part through an external second crease. The internal first part runs substantially transversely, preferably perpendicular, to the longitudinal axis of the container. The intermediate second part forms a preferably straight slope. The external third part forms a shorter inclined plane with a greater slope here. The first crease and / or the second crease can be provided by an angular transition or by a rounded transition.

[0021] Additional structural measures can also be implemented to supplementarily or alternatively support manual engagement within the receiving area for releasing the hanging element from its fixed first position. For example or according to the invention, the receiving area may particularly have a crease in the direction of the outside of the container, preferably a second crease, in the direction of the opening of the container. Thereby, the opening for engaging or engaging the hanging element from below can be enlarged. Alternatively and / or supplementarily, the upper edge of the receiving area can be at least partially constructed to be recessed. Thereby, it is easier to access the hanging element to convert the hanging element from its first position to its second position.

[0022] In another variant, the container according to the invention is characterized in that first and second receiving areas for the hanging element are constructed within the bottom of the container. Preferably, the hanging element can be moved from the first receiving area into the second receiving area and can move back again. Thereby, for example, unilateral wear of the hinge can be reduced or avoided. In one design, the first and second receiving areas are arranged opposite each other and / or are constructed to be substantially the same.

[0023] Another embodiment of the container is characterized in that a foot area is constructed within the outer area of the bottom for standing the bottle upright, and / or in that a groove is preferably constructed within the bottom starting from the foot area, through which the receiving area for the hanging element extends. The groove particularly supports an ergonomic grip of the hanging element using the fingers.

[0024] In one variant, the hanging element has a notch in the region of its second end, preferably the notch has the form of a round hole or a slot, for receiving a hanging device. When the container is used in its operating state, the hanging device can thus be engaged through the notch during the required operation of the container. Thus, a universal use of the container with a large number of different hanging devices can be achieved.

[0025] For achieving a particularly simple manufacture of the container, in one variant the container is made of a single material. Suitable materials are for example polypropylene (PP) or polyethylene (PE), such as high density polyethylene (HDPE). Other plastic materials can also be used, such as copolymers having monomer units of propylene, ethylene, butene, butadiene, styrene and / or isoprene.

[0026] Containers known from the prior art usually have a multi-layered structure, while the container according to the invention is in one variant constructed from a single material layer in one variant. This also facilitates the manufacture and subsequent reuse of the container. However, the container can also be constructed as multi-layered.

[0027] The container can for example be constructed from a transparent or translucent material. In this way, the filling state of the enteral nutrient solution contained within the container can be easily recognized from the outside. The container can also be opaque in parts due to applied labels, applied printed parts and / or applied coatings.

[0028] Preferably, the cross-section of the container is enlarged in the region of the bottom relative to the middle region of the container. Thereby, on the one hand, the standing stability can be improved when the container is, for example, to be placed on a table; on the other hand, when the container is suspended head-up by its suspension means, the container is thereby made easier to grasp.

[0029] In another variant, at least in the part of the inner container, the cross-section has convex curved parts and straight parts adjacent to each other in an alternating arrangement, and these parts are substantially in the middle part of the container in the longitudinal extension direction of the container. Here, in one variant, the straight parts and the convex curved parts are exactly opposite to each other. In this way, the container can be grasped particularly simply and reliably. In addition, due to the arrangement of these straight parts, the container can be stored not only in the upright position but also in the lying-flat position, that is, by using the straight parts as the upright surface and the lying-flat surface. Reliably positioning the suspension element in its first position is also advantageous for the case where the container is stored in the lying-flat position. Because the container does not have unwanted protruding elements that may increase the space occupation requirement during lying-flat storage.

[0030] At the transition between the convex curved part and the straight part, an edge (or a corner in the cross-section) appears on the side wall of the container, so that the aforementioned cross-section can also be substantially regarded as a polygonal cross-section.

[0031] In one variant, the width of the straight part in the part of the container closer to the opening than the middle part is greater than the width in the middle or the middle part of the container. In this way, easier graspability of the container is achieved. Because the user who intuitively guides the container grasps the container in this wider-structured straight part. Since this part is above the middle part of the container, in this case, the grasping is performed in a region significantly above the center of gravity of the container. Therefore, self-stabilization of the container is achieved, thereby ensuring more reliable manual transportation and more reliable operation of the container.

[0032] In another variant, the cross-section of the container may have, at least in the following part, convex curved portions and at least one concave curved portion arranged in an alternating manner, said portions being closer to the bottom than the middle part of the container. Here, the convex curved portions and the concave curved portion or the plurality of concave curved portions are preferably arranged directly following one another. For example, the straight portion explained above may be replaced by a concave curved portion in this area of the container. Thereby, a cross-section of the container corresponding to an abstracted flower shape is obtained. The advantages of such a construction occur particularly in the case where the suspension element extends between two mutually opposed concave curved portions in its first position or between an opposed convex curved portion and the straight portion, as proposed in one variant. Thus, the concave curved portion enables a particularly simple grasping of the suspension element, such that the suspension element can be simply converted from its first position to its second position and, if necessary, from its second position to its first position.

[0033] In one variant, it may be provided that there is only a single concave curved portion, which is arranged between two convex curved portions. Opposite this concave curved portion, for example, a straight portion may be arranged in the cross-section. In this variant, it is particularly proposed that the second end of the suspension element faces the concave curved portion in the first position of the suspension element, while the hinge device on the first end of the suspension element is arranged on the straight portion or the convex curved portion of the cross-section of the container. Also in this variant, good accessibility of the second end of the suspension element is obtained, such that the suspension element can be simply converted from the first position to the second position and from the second position to the first position.

[0034] In one variant, the container, the suspension element, the hinge device and in particular the base are constructed as one piece. This facilitates the manufacture of the container and ensures simple but reliable operation of the container as well as the suspension element.

[0035] In another variant, the side wall of the container is constructed without ribs running horizontally and / or vertically. Such ribs may be used in containers for enteral nutrient solutions to cause better heat transfer, for example when the nutrient solution is to be kept at a certain temperature. Of course, such ribs require the use of more material and furthermore a more expensive manufacturing method for the container. In addition, residues of the nutrient solution contained in the container often remain in such ribs, making it difficult to achieve simple emptying of the residues from the container due to these ribs. Therefore, for cost and efficiency reasons, it is advantageous to omit these ribs.

[0036] According to the present invention, a receiving area for hanging elements is constructed inside the bottom, and the hanging elements in their first position can be received within the receiving area. The receiving of the hanging elements is carried out such that the hanging elements do not protrude beyond other areas of the container. For example, the hanging elements can be arranged flush with other areas of the bottom. In particular, the height difference between the receiving area on the outer side of the container and the remaining area of the bottom in the longitudinal extension direction of the container is at most 15 mm. The height difference in the longitudinal extension direction of the container between the receiving area and the remaining area of the bottom can, for example, be in the range of 0.5 mm to 15 mm.

[0037] In one variant, the volume of the container is greater than 150 ml, in particular greater than 300 ml, in particular greater than 400 ml, in particular greater than 500 ml, in particular greater than 600 ml, and more particularly greater than 750 ml. Suitable volumes are, for example, in the range of 300 ml to 500 ml, where other ranges formed by the aforementioned upper limits can also be conceived and proposed.

[0038] The container can be manufactured, for example, by extrusion blow molding. In an alternative variant, manufacturing by stretch blow molding is proposed.

[0039] In another variant, the container has connecting means, preferably a thread, for receiving a lid around the opening. The lid can, for example, have a connecting portion by which the container can be connected to a guiding system through which enteral nutrient solution accommodated in the container can be delivered to a patient.

[0040] The variants described in connection with the explained container can be transferred in a similar manner in any combination to the separately described combinations.

[0041] The container explained above is particularly suitable for use in combination with a lid having the features described below.

[0042] Such a lid has connecting means, preferably a thread, which can preferably engage with a mating connecting part, preferably a mating thread, on the container for accommodating enteral nutrient solution. Thereby, the opening in the container can be covered. In addition, the lid has a connecting nipple for connecting a hose line. This connecting nipple can, for example, be constructed as a conventional port for introducing a cannula.

[0043] Preferably, an opening device is provided on the inner side of the lid. This opening device consists of or comprises two parts. The first part is preferably in form-fitting and / or force-fitting connection with the lid. The first part can be, for example, clipped or latched into the lid. The first part is preferably permanently connected to the second part of the opening device. The second part of the opening device particularly comprises a cutting edge. The opening device can now be in the original state or in the open state. In the original state, the second part of the opening device can be fixed to the first part of the opening device using at least one fixing element. Thereby, the second part of the opening device cannot move away from the first part of the opening device. Instead, the two parts are held to each other by the fixing element. In the open state of the opening device, the fixing element no longer prevents the movement of the second part of the opening device relative to the first part of the opening device. Instead, the second part of the opening device can move relative to the first part of the opening device in the open state of the opening device. The second part can be permanently movable in the open state. The second part can also be movable in the open state such that the second part can only move from the original state to the open state once and is then locked, for example, latched, if necessary. Preferably, the second part is permanently connected or remains connected to the first part.

[0044] Although the permanent connection between the first part of the opening device and the second part of the opening device in the original state of the opening device does not permit relative movement or significant relative movement between the two parts, such relative movement is possible in the open state of the opening device. By means of this opening device, it is possible to open a covering that closes an opening in a container in a standard-compliant manner. That is, when a stylet or another object is introduced into the lid through a connecting adapter, it is not the stylet itself that causes the opening of the covering of the container. Instead, the stylet causes the opening device to switch from the original state to the open state, such that the second part of the opening device then causes the opening of the covering of the container. The opening or aperture in the covering of the container is produced by the cutting edge of the second part, by cutting here. The cutting edge enables a better-defined opening of the covering compared to an opening that is achieved substantially by tearing.

[0045] This covering can in particular be a film, such as an aluminum film. Composite materials can also be used for the covering. Such coverings are known per se. This lid is suitable for containers that are closed with such a covering. When the covering is opened by means of the opening device, the lid additionally causes the covering of the opening in the container. A liquid contained in the container, such as enteral nutrient solution, can then only flow out of the container through the opening in the lid. This opening in the lid is preferably provided by a connecting adapter for connecting a hose line.

[0046] That is, when a hose line carrying a stylet or another end piece is introduced into the interior of the lid through the connecting adapter, the hose line first causes the opening device to switch from the original state to the open state and then serves to discharge the liquid contained in the container.

[0047] For the user, the cap according to the invention has great advantages in that the operation of the cap is different from that of caps known from the prior art. In particular, no additional elements are required apart from the cap and the hose line configured with an end piece to bring the cap into the intended operation. The cap according to the invention also facilitates opening the covering of the container due to the opening device present inside it. In addition, the cutting edge of the opening device results in a neat opening of the covering, such that a container opened with such a cap has a better outflow or pouring behavior compared to a container opened in a classical manner by piercing a needle or another end piece of the hose line into the covering of the container.

[0048] The second part includes a blade-shaped configuration. Here, the cutting edge of the blade or generally the cutting edge of the second part of the opening device is preferably constructed on the side of the second part of the opening device that faces away from the first part of the opening device. If the second part of the opening device then leaves the first part (e.g., flips open) in the open state of the opening device, the covering of the container arranged below the second part of the opening device can be contacted in a particularly simple manner by the blade-shaped or knife-shaped contour and then cut open. In one embodiment, the second part of the opening device is partially or completely constructed as a blade on the underside of the blade part.

[0049] In other words, the second part of the opening device is used to cut open the covering of the container on which the cap is placed. As mentioned before, the covering of the container can in particular be made of an aluminum film or preferably a composite material containing aluminum. In this variant, the second part of the opening device penetrates into the covering with its knife-like cutting edge and causes a neat cut of the covering, thereby advantageously influencing the pouring or outflow behavior of the liquid from the container compared to solutions known from the prior art.

[0050] The fixing element can additionally assume the function of a hinge element in the first variant. In another variant, the first part of the opening device and the second part of the opening device are connected to each other not only by the fixing element but also additionally by a hinge element. The hinge element is here constructed as a separately formed component from the fixing element. With such an arrangement, it can be achieved in a simple manner that the second part of the opening device is connected or remains connected to the first part of the opening device, even if the opening device is no longer in its original state. The hinge element can for example be constructed as a sheet-like connecting element that has a certain flexibility and allows the relative connection of the second part of the opening device with respect to the first part of the opening device. For simplicity of manufacture, the opening device can for example be made as an integrally injection-molded part.

[0051] In a further variant, the hinge element abuts on the first end region of the second part of the opening device. A hinge axis is then defined on this first end region about which the second part of the opening device can move or pivot relative to the first part of the opening device.

[0052] In a further variant of the opening device, the cutting edge includes a cutting edge tip which is configured within the second end region of the second part of the opening device, the second end region being opposed to the first end region in the longitudinal extension direction of the opening device. In this design, the covering of the container is first punctured by the cutting edge tip and then cut open by the cutting edge, in particular by the cutting edge of the cutting edge. By means of the cutting edge tip, the cutting edge or the cutting edge of the cutting edge can be better placed on the covering for cutting, since the cutting edge can engage in the puncture opening. Thereby, the cutting open is facilitated.

[0053] To provide the cutting edge tip, in a further variant the underside of the cutting edge and the side surface of the cutting edge run at an acute angle to each other. The side surface of the cutting edge is configured within the second end region of the second part of the opening device. The second end region is opposed to the first end region in the longitudinal extension direction of the opening device. That is, when the second part of the opening device moves about the hinge axis, the first end region travels the greatest distance along the arc of the entire second part of the opening device. The acute angle between the underside of the cutting edge and the side surface of the cutting edge now causes the second part of the opening device to be able to pierce, i.e., initially open the covering, particularly well. That is, the acute angle makes the cutting edge sufficiently sharp for cutting the covering.

[0054] In a further embodiment, the second part of the opening device has at least one wing which is arranged on the side surface of the cutting edge. Preferably, at least one wing is arranged on the upper side of the cutting edge. This wing serves the function of squeezing the covering to widen the opening produced in the covering by the cutting edge. The covering is first punctured by the cutting edge tip and then further cut open by the cutting edge of the cutting edge. The wing pushes the cut-open covering to the side. Thereby, the slit opening produced by the cutting edge is widened to the side, thereby improving the flow-through. In a preferred design, the second part of the opening device has two wings.

[0055] At least one wing is positioned offset from the cutting edge tip, particularly in the direction of the first end region of the second part of the opening device, on the cutting edge. This particularly supports the cooperation of the cutting edge and the wing which is carried out by first opening the covering by the cutting edge and then widening the produced slit opening by the wing. In one design of at least one wing, the wing has a width increasing in the direction of the first end region of the second part of the opening device. Thereby, the slit opening produced by the wing can be gradually widened and thus enlarged.

[0056] In a further variant, the first part of the opening device has a through-opening in the central region of the first part. An attachment of the hose line can be guided through this through-opening to contact the second part of the opening device. This attachment of the hose line can also be referred to as an end piece and is, for example, a cannula. In this variant, it is particularly simple to guide the hose line that is guided through the connecting stub of the lid also through the first part of the opening device, so that the end piece or attachment of the hose line can contact the second part of the opening device. When a corresponding pressure is applied to the second part of the opening device, the opening device is converted from the original state to the open state.

[0057] In one embodiment of the lid, the holding force of the first part of the opening device within the lid is greater than the force exerted by the fixing element to fix the second part of the opening device to the first part of the opening device. With such a design, it is ensured that the attachment of the hose line actually only causes a relative movement of the second part of the opening device towards the first part of the opening device when the opening device is converted from the original state to the open state, without causing the opening device to become loose from the lid. As already mentioned above, the first part of the opening device can, for example, be clamped in the region provided therefor in the lid. But the first part can also be mounted, for example, by means of a snap ring.

[0058] In one design, at least one fixing element has a cross-section that tapers in the direction from the first part of the opening device towards the second part of the opening device. Thereby, on the one hand, a sufficiently mechanically stable connection between the first part and the second part of the opening device can be provided; on the other hand, this also supports the targeted loosening of the second part from the first part, especially when introducing the attachment of the hose line. In a preferred design, two fixing elements are provided.

[0059] In one design of the connecting stub, the connecting stub has a selection device. Preferably, the connecting stub partially has a geometry configured as a cross, preferably a cross-shaped opening. With such a geometry, it can be ensured that only an attachment of the hose line that matches this geometry can be introduced into the connecting stub. In this way, the lid can be specifically adapted to a container for enteral nutrient solution. Then, a cannula or a cannula for the intravenous administration of a drug or another solution cannot be guided through such a connecting stub. Therefore, in this way, the confusion of different containers for different purposes of use can be avoided. The selection device is particularly arranged in the upper region of the connecting stub. Preferably, the upper side of the connecting stub is provided by the selection device.

[0060] In another variant, a seal is arranged between the connection nipple and the opening device, and the attachment of the hose line can be guided through the seal. Preferably, the seal is provided with a slit that matches the geometry of the selection device. In this way, it is possible to support, if required, that only attachments of the hose line with a defined geometry can be connected. If the connection nipple already has a specifically configured geometry (for example, a geometry configured as a cross), such a seal can then be inserted, for example. Then, the seal supports the function of the connection nipple such that essentially only connection nipples of the hose line with a specific geometry can be guided through the connection nipple. On the other hand, if the connection nipple has an arbitrarily configured geometry, it is also conceivable to precisely insert this seal. Then, such a seal can result in only connection nipples with a specific geometry being able to be guided through the seal and in the opening device being converted from the original state to the open state. Thus, it is also possible, with such a seal - similar to with a specific internal geometry of the connection nipple - to prevent the possible use of a "wrong" connection nipple to open a container that has a lid placed on it.

[0061] In another variant, the lid has a cap for closing the connection nipple. Thereby, contamination of the connection nipple before use of the lid can be effectively countered.

[0062] The cap for closing the connection nipple can, for example, be connected to the lid in a reversible manner. For example, the cap can be connected to the lid by means of a thread. The cap can be screwed onto the lid or unscrewed from the lid. In one variant, it is proposed that the cap is arranged and designed to be removed from the connection nipple by breaking off from the connection nipple. The advantage of this variant is directly evident to the user as to which lid has already been used and which lid is still in the new factory state. Thereby, protection of the original seal is provided. In this way, contamination of enteral nutrient solutions or other liquids located in the container covered by the lid can be avoided.

[0063] In another variant, the second part of the opening device is arranged substantially parallel to the first part of the opening device in the original state, while the second part is arranged transversely or can be arranged transversely to the first part of the opening device in the open state. That is, the relative movement between the first part of the opening device and the second part of the opening device is configured as a flipping movement of the second part relative to the first part in this variant. Thereby, it is possible to ensure a particularly controlled and repeatable introduction of the second part of the opening device into the covering arranged below the lid. Such a repeatable opening of this covering cannot be achieved with solutions known from the prior art because the tearing behavior of the covering depends decisively, for example, on the pressure with which a lancet or another connecting piece of the hose line pierces through this covering. With the lid equipped with the opening device, this dependency is at least reduced or even largely eliminated. Because the opening device causes an always substantially identical opening behavior of the underlying covering largely independently of the pressure exerted by the connecting piece of the hose on the opening device.

[0064] In one variant, the lid has at least one vent which is closed by a filter. The filter allows gases to pass through, but is impermeable to liquids. In this way, ventilation of the container provided with the lid can be achieved if the covering of the container has been opened and a flow connection has been created between the interior of the container and the lid. If the liquid stored in the container leaves the container via a hose line through a connecting nozzle from the lid and thus from the container, a corresponding volume of gas can flow into the container through the filter. In this way, a pressure balance is created between the interior of the container and the atmosphere surrounding the container.

[0065] The first part of the opening device and the second part of the opening device are preferably made of a material which does not deform under the forces applied during the intended use of the lid. In this way, it can always be ensured that the covering is reliably cut through by the second part of the opening device. Suitable materials are, for example, plastics such as polypropylene, polyethylene or polycarbonate. The wall thicknesses of the individual parts of the opening device should preferably be greater than the thickness or wall thickness of the covering to be cut through by the opening device.

[0066] The opening device for the lid according to the invention can also be present as an opening device. The opening device has a first part which is form-fitting and / or force-fittingly connected to or connectable to this lid, and a second part which is preferably permanently connected to the first part and which comprises a cutting edge. Here, the second part of the opening device can be fixed to the first part of the opening device by at least one fixing element in the original state of the opening device. In the open state of the opening device, the second part of the opening device can move relative to the first part of the opening device.

[0067] This opening device can be installed in different lids. The exact construction of the lid is not crucial here. All that matters is the provision of a receiving part for the opening device.

[0068] The variants described in connection with the lid explained can be transferred in a similar manner in any combination to the other opening devices described separately.

[0069] As already mentioned, the lid described above is particularly suitable for being placed on a container for receiving enteral nutrient solutions. The invention thus also relates to a combination comprising in particular a lid according to the foregoing explanations and a container for receiving enteral nutrient solutions. The container has an opening through which the enteral nutrient solution can enter and leave the container. Connecting means for receiving the lid, for example a thread, are arranged around the opening. The connecting means of the lid, for example a thread, and the connecting mating part of the container, for example a thread, engage with one another such that the lid covers the opening and seals the opening in a liquid-tight manner. A sealing part can be provided in the lid or on the container if required. The opening is in particular provided with a covering part which must be opened in order to be able to transfer the enteral nutrient solution contained in the container into the lid or through the lid into a hose system.

[0079] Figure 1Fig. 0 shows a perspective view of the bottle 1 as a container for accommodating enteral nutrition solutions. The bottle 1 extends along a first longitudinal extension direction L1 and has an opening 2 at its upper end and a bottom 3 at its lower end. A hanging element 4 is formed on the bottom 3, which will also be simply referred to as the hanger 4 hereinafter.

[0080] A side wall 5 is constructed between the opening 2 and the bottom 3, and the shape of the side wall 5 will be explained in detail in connection with additional drawings.

[0081] Around the opening 2, for example, a thread 6 is constructed, onto which a cap can be screwed.

[0082] In Figure 2A the bottle 1 in Figure 1 is illustrated in a side view. Figure 2C An enlarged view of the bottom region and the hanger is also shown here. Figure 2D And Figure 2E the bottom region of the bottle 1 with the hanger 4 formed on the bottom 3 is again shown in a perspective view. In this figure, it can be well seen that the hanger 4 extends along a second longitudinal extension direction L2 in the opened state, and the second longitudinal extension direction L2 is the same as the first longitudinal extension direction L1 of the bottle 1 in Figure 2A the illustrated case. The length L of the hanger 4 is between 25 mm and 35 mm. The thickness of the hanger 4, especially in the region of the opening 17, is approximately 1.5 mm to 3 mm.

[0083] In the bottom region of the bottle 1, there is a receiving region 13 for the hanger 4. The receiving region 13 is constructed as a recess in the bottom 3 of the bottle 1. The receiving region 13 extends over the entire width of the bottle 1. In this example, two receiving regions 13 are provided. The hanger 4 has a first end 7, which is arranged in the region of the bottom 3 of the bottle 1. Here, the first end 7 is connected to the bottom 3 by a hinge 8 integrally formed on the hanger 4. The first end 7 is constructed opposite to the second end 9 of the hanger 4 in the second longitudinal extension direction L2.

[0084] The hinge 8 is a so-called film hinge. The thickness of the hinge 8 is approximately 0.2 mm to 0.6 mm. The hinge 8 extends transversely to the second longitudinal extension direction L2 over a first width B1. This first width B1 can substantially correspond to a second width, over which the free second end 9 of the hanger 4 extends transversely to the second longitudinal extension direction L2. Thereby, the hanger 4 is integrally and compactly constructed and has ends 7 and 9 corresponding to each other in its widths B1 and B2. The width B1 of the hinge 8 is between 14 mm and 21 mm. The width B2 of the free end 9 of the hanger 4 is between 20 mm and 26 mm. Preferably, B1 is less than B2.

[0085] The hinge 8 of the suspension member 4 is not placed directly on the bottom 3 of the bottle 1 here. The hinge 8 is arranged on a base 21 which provides a transition to the bottom 3 of the bottle 1. In the illustrated embodiment, the base 21 has a ridge on the side where the hinge 8 is connected thereto, which ridge extends transversely to the longitudinal axis L1 and preferably extends over the entire receiving area 13. Thereby, in particular, it facilitates the release of the suspension member 4 from its fixed first position (for which see below).

[0086] On the second end 9 of the suspension member 4, two lateral, for example finger-shaped or nose-shaped, protrusions 10 are constructed, in particular by a reduction in the width of the suspension member 4 in the direction of the hinge 8. The width B3 reduced with respect to B2 is in the range from 17 mm to 23 mm. The protrusions can have a width of from 0.5 mm to 3 mm here. By means of the two protrusions 10, when the suspension member 4 is to be converted into the first position, the suspension member 4 can be fixed on the bottom 3 or within the receiving area 13, in which first position the suspension member 4 extends substantially along the bottom 3. In Figures 2A to 2E FIG., the suspension member 4 is shown in its second position, in which the suspension member 4 extends at an angle to the bottom 3. In the case illustrated in the drawing, the suspension member 4 is substantially perpendicular to the bottom 3.

[0087] The receiving area 13 has lateral depressions 22 for receiving the two protrusions 10 of the suspension member 4. In particular, the receiving area 13 has depressions 22 on its two side parts respectively. In the first state of the suspension member 4, the two protrusions 10 engage into the depressions 22. Thereby, the suspension member 4 is fixed in its first position in a releasable manner. The depression 22 has a height V of, for example, from 1 mm to 7 mm H and / or a depth V of from 2 mm to 10 mm T . In particular, the protrusions 10 are snap-fitted into the depressions 22. The protrusions 10 and the lateral depressions 22 here form a connecting means for fixing the suspension member 4 in a releasable manner within the receiving area 13.

[0088] Preferably, the suspension member 4 is fixed in its first position not rigidly but movably. This is achieved in particular by choosing the thickness of the free end 9 of the suspension member 4, and in particular of the entire suspension member 4, to be at least less than the height A of the receiving area 13 for the suspension member 4 H , and / or by arranging the hinge 8 of the suspension member 4 not directly on the bottom 3 of the bottle but on the base 21. In particular, for this purpose the thickness of the free end 9 is also chosen to be less than the height V of the depression 22 H . Thereby, in particular, it facilitates the release of the suspension member 4 from its first position, since manual intervention between the suspension member 4 and the bottom 3 is facilitated.

[0089] To further support manual intervention within the receiving area 13, for example by means of a fingertip and / or fingernail, for loosening the suspension element 4 from its fixed first position, additional structural measures can be taken. For example, at least the upper outer edge 23 of the receiving area 13 is configured to be concave and in particular curved (see Figure 2C ). Thereby, the suspension element 4 can be more easily grasped to convert the suspension element 4 from the first position illustrated in Figure 3 to its second position (see Figure 2A ).

[0090] In one embodiment, the receiving area 13 has a height A that decreases from the outside towards the longitudinal axis L1 of the bottle 1 H (see Figure 2E ). Thereby, the conversion of the suspension element 4 from its fixed first position to its extended second position is further supported. In the illustrated embodiment, a crease 24-1 is provided within the receiving area 13, and an external second crease 24-2 is also provided towards the outside of the container 1. The receiving area 13 is thus provided by three parts 13-1, 13-2, and 13-3. The first inner part 13-1 runs substantially transversely, preferably perpendicularly, to the longitudinal axis L1 of the container. The inner first part 13-1 transitions to the intermediate second part 13-2 through the first crease 12-1. The inner first crease 24-1 is positioned at an interval of 5 mm to 10 mm from the base 21. The intermediate second part 13-2 forms a preferably straight inclined plane. The height A of the receiving area 13 H increases towards the outside of the container 1 here. The external second crease 24-2 is in the region of the rear edge of the substantially receiving area 22. The external third part 13-3 forms a shorter inclined plane with a greater slope here. The height A of the receiving area 13 H thus further increases towards the outside. Thereby, the loosening of the suspension element 4 from its fixed first position is further supported. For example, the receiving area 13 has a height A of 6 mm to 13 mm on the outside of the bottle 1 H . The height A H decreases towards the longitudinal axis L1, for example, to a value of 0.5 mm to 5 mm. The width A of the receiving area 13 with the recess 22 B is between 20 mm and 30 mm. Without the recess 22, the width A B decreases by approximately 0.5 mm to 4 mm. The recess 22 can have a width of 0.25 mm to 2 mm here. The width B2 of the suspension element 4 at its free end 9 is greater than the A of the receiving area 13 without the recess 22 B , but less than the width A of the receiving area 13 with the recess 22 BIn this way, a releasable fixation is maintained, but the movability of the suspension part 4 in its first fixation position is also achieved. The first fold 24-1 and / or the second fold 24-2 can be provided by a bent transition part or by a rounded transition part.

[0091] Preferably, a region 25 is also constructed between the free end 9 of the suspension part 4 and the hinge 8, and the region 25 has a narrowing part or a constriction part. The narrowing part or the constriction part is arranged between the opening 17 and the hinge 8 here. This region 25 has a reduced width B4 relative to the hinge 8 and the free end 9 of the suspension part 4. Preferably, the width B4 is in the range of 10 mm to 16 mm. This narrowing part provides, for example, a gripping area 25 for the index finger and the thumb, and can support the suspension of the bottle 1. The narrowing part 25 is constructed recessedly or at least partially recessedly here. The inwardly arched narrowing part 25 enables, for example, the engagement by fingers in the first position of the suspension part 4. The suspension part 4 particularly also has a different shape from the receiving area 13 for the suspension part 4 through this narrowing part 25.

[0092] In Figure 1 the illustrated embodiment, except for the suspension part 4, the bottle 1 is constructed substantially mirror-symmetrically. Two receiving areas 13 for the suspension part 4 are provided on both sides of the hinge 8. The receiving areas 13 are constructed substantially identically here.

[0093] Figure 2B Shows Figure 2A of the bottle along Figure 2A the line A-A extending in the middle area of the bottle 1. In this cross-sectional view, it can be seen that the cross-section is composed of alternately (alternating) convexly curved (i.e., outwardly arched) parts 11 and straight parts 12. Here, two convexly curved parts and two straight parts 12 are opposed to each other. The straight parts 12 substantially form the side wall 5 of the bottle 1. The convexly curved parts 11 substantially form the corners of the bottle 1. The upper recessedly curved edge 23 is substantially arranged in the area of the straight parts 12. In particular, the receiving area 13 is substantially arranged in the area of the straight parts 12.

[0094] Figure 3 Here, the bottle 1 of Figure 2A is shown in a side view, where the suspension part 4 (simply illustrated in the figure) is now stored in the receiving area 13 of the bottom 3 in its first position, and the first position corresponds to the storage position. Thus, the bottle 1 can stand upright on the bottom 3 without interference from the suspension part 4. The opening 2 is directed upward here, that is, the bottle is in an upright position.

[0095] In the illustrated embodiment, the suspension part 4 does not finally lie flush with the lower side of the remaining part 14 of the bottom 3, but is offset upward and into the bottle interior relative to the remaining part 14 (for this, see, for example,Figure 2E and Figure 3 )。This remaining portion 14 of the bottom 3 includes the foot area 14a of the bottle 1. The foot area 14a is provided by the outer area or the edge area of the bottom 3 (for this, see Figure 2E ). In the illustrated example, the foot area 14a is formed by four feet 14a. The feet 14a extend respectively at the corners within the bottom 3. In addition, the bottom 3 has a groove 14b through which the receiving area 13 for the suspension member 14 extends. The groove 14b is preferably divided in the middle by the receiving area 13. The receiving area 13 is upwardly offset relative to the bottom of the groove 14b in the direction of the opening 2 of the container 1. The groove extends from the outer area of the bottom 3 that forms the feet 14a towards the middle of the bottom 3. The groove 14b provides an area for engaging and / or guiding the fingers, whereby grasping the suspension member 4, for example by the thumb and index finger, can be supported. To particularly increase the stability of the suspension member 4, the base 21 extends from one side of the groove 14b through the receiving area 13 to the other side of the groove 14b. The exact arrangement of the suspension member 4 within the receiving area 13 is defined by a height difference such that the bottom of the receiving area 13 is offset backwards relative to the remaining area 14 of the bottom 3 in a first longitudinal extension direction L1 (for this, see the foregoing description).

[0096] In Figure 4 the Figure 3 bottle 1 is shown in its use state. In this state, the suspension member 4 is in its second position, i.e., the suspension member 4 projects angularly from the bottom 3 of the bottle 1. Here, the hook 6 serving as a hanging device engages through an opening 17 configured as a notch within the suspension member 4. The bottle 1 is arranged here such that its opening 2 points downwards. Here, the thread (see Figure 1 ) is covered by a cap 8 having a connection part 19 for guiding the system 20. Through the guiding system 20, enteral nutrient solution within the bottle 1 can be supplied to a patient. Here, the nutrient solution can leave the bottle 1 under the action of gravity due to the downward arrangement of the opening of the bottle.

[0097] If it is desired to interrupt the supply of the nutrient solution, for example, a valve within the guiding system 20 can be closed. Alternatively, the bottle 1 can also be removed from the hook 16, the suspension member 4 can be converted from its second position illustrated in Figure 4 to its first position illustrated in Figure 3 , and the bottle can be placed on a corresponding placement surface with its bottom 3 such that the opening of the bottle points upwards again.

[0098] The volume of the bottle 1 can be in the range of 150 ml to 1000 ml, such that a sufficient amount of enteral nutrient solution can be stored within the bottle 1. The volume of the bottle 1 illustrated in Figure 1 is, for example, 500 ml.
