EP3274266B1 - Sealing cap for a container for holding a medical liquid - Google Patents

Description

The invention relates to a closure cap for a receptacle for holding a medical fluid according to the preamble of claim 1.

Such a closure cap comprises a cap body which delimits an interior space and has at least one opening. At least one connection device is arranged on the cap body, to which a conveying device for supplying a medical liquid into the container or for removing a medical liquid from the container can be connected. The connection device has a sealing element arranged on the cap body, which is arranged at the opening for sealing closure. A conveyor device for connecting the conveyor device can be attached to an outside of the sealing element facing away from the interior.

Such a conveying device can be configured, for example, as an injection syringe, which can be attached to the sealing element with an injection cannula and inserted into the sealing element in an attachment direction, so that the sealing element is pierced by the injection cannula. Such an injection syringe is used in particular to supply a medical liquid into the container. To remove a medical fluid from the container, however, an infusion set can be used, for example, which is attached to the sealing element with a mandrel, which is also referred to as a spike, in such a way that the sealing element is pierced by the mandrel and thus creates access to the container becomes.

With one from the WO 2006/042579 A1 known closure cap, two connection devices are provided, each with a sealing element. One of these connection devices is used to supply a medical liquid into a container connected to the closure cap, for example a bottle, while the other connection device is used to remove a medical liquid from the container.

Another, from which WO 2010/066373 A1 In the known closure cap, three connection devices are provided, of which a first one is used to supply a medical liquid by means of an injection syringe, a second one is used to remove a medical liquid by means of an infusion set that has a mandrel and a third one is used to provide a so-called needle-free access. The sealing element of the third connection device has a slot opening which makes it possible to attach a conveying device, for example a syringe, to the sealing element with a —needeless — connecting piece in order to open the sealing element and in this way to supply a liquid to the container.

With one from the US2008011707 A1 Known closure cap according to the preamble of claim 1, a sealing element is provided which is convex on the outside.

Legal requirements may make it necessary to wipe or dab the outside of the sealing element before disassembling a conveying device, for example an injection syringe for supplying a medical liquid or an infusion set for removing a medical liquid.

The object of the present invention is to provide a closure cap in which the disinfection of a sealing element arranged thereon is simplified.

This object is achieved by an object with the features of claim 1. The closure cap according to the invention closes access to a container. For example, the cap closes the opening in the bottle neck of a bottle.

Accordingly, the sealing element is convex on its outside.

The outer side of the sealing element protrudes outwards from an upper side of the cap body.

Because the sealing element is convex on the outside, it can be ensured that after wiping or dabbing no disinfectant liquid remains on the sealing element, but can be removed in a reliable, simple manner by wiping or dabbing. Because the outside of the sealing element protrudes outwards from an upper side of the cap body, the sealing element can be easily accessed by wiping along the upper side with a suitable disinfection tool, for example a swab or a wiping cloth, in this way dab or wipe the outside of the sealing element.

The outside of the sealing element corresponds to the side of the sealing element that is visible from the outside and to which a conveying device, for example an injection syringe or an infusion set or also another conveying device, can be attached. The outside is thus accessible from the outside in order to connect a conveyor to the closure cap. In one embodiment, the sealing element has a central thickness of 2 mm to 8 mm and / or an overall diameter of 4 mm to 14 mm.

In another solution, the outside projecting is part of a sealing head of the sealing element, which extends through the opening. The sealing element lies with its sealing head in the opening and closes the opening in this way, the outside formed on the sealing head pointing outwards and thus facing away from the interior of the closure cap. In one embodiment, the sealing head has a diameter of 2 mm to 10 mm. The central region of the sealing head for providing the convex outside preferably has a thickness which is 0.1 to 1 mm greater than the edge region of the sealing head. A center of the convex outside of the sealing element is preferably 0.1 to 1 mm, preferably 0.3 mm to 0.7 mm, above an outer upper edge of a sealing head of the sealing element. This improves the accessibility to the outside of the sealing element.

In an initial state, a break-off piece is connected to the cap body in such a way that the sealing element is completely covered on the outside. The break-off piece encloses the outside of the sealing element and thus closes the outside from the outside, so that no dirt in the form of solid or liquid contaminants can get onto the outside.

In the initial state, the break-off piece is integral, that is to say in one piece, connected to the closure cap. The closure cap can, for example, be produced together with the break-off piece as a molded plastic part, for example by means of plastic injection molding. The break-off piece is connected to the cap body via a predetermined breaking point in such a way that the break-off piece can be separated from the cap body along the predetermined breaking point, in particular broken off, in order to remove the break-off piece from the cap body.

In an advantageous embodiment, the predetermined breaking point runs around the opening, so that the break-off piece is connected to the cap body along a connecting line running around the opening and can be separated from the cap body along this connecting line in order to release the sealing element and a conveying device to the outside of the To be able to attach sealing element.

In one embodiment, an interior or space between the break-off piece and the outside of the sealing element is provided sterile. The outside of the sealing element is thus already sterile in the state in which the break-off piece is still connected to the closure cap. Disinfecting the outside of the sealing element after removing the break-off piece and before attaching a conveyor, in particular by wiping or dabbing, is no longer necessary in this case. However, if, for example, legal requirements make such disinfection necessary, this additional disinfection can be carried out more easily, in particular by the convex outside of the sealing element.

In a specific embodiment, the closure cap can have, for example, a first connection device for removing a medical liquid and a second connection device for supplying a medical liquid. At the The closure cap is thus provided with two connection devices, one of which is designed, in particular, for removing a medical liquid and of which the other is designed in particular for supplying a medical liquid.

The connection devices can be designed differently in order to enable the connection of different delivery devices, for example an injection syringe or an infusion set. It is also conceivable and possible, however, to design the connection devices identically and in particular to use the same sealing elements on the connection devices.

In a first variant, each connection device can have a sealing element, the sealing elements of the connection devices being of identical design. The same sealing elements are thus used on the connection devices, it being possible for identical holding devices to be provided on the connection devices, for example in the form of cutouts provided on the closure cap for receiving the sealing elements. This simplifies the overall design of the closure cap because the same parts can be used to manufacture the connection devices.

For example, each sealing element in this variant can have a sealing head, which forms the outside, and a sealing body adjoining the sealing head. The sealing body can be connected to an annular collar by means of a circumferential circumferential flange, a clamping connection with the closure cap being produced via this annular collar. For example, the collar can lie in an associated recess of the closure cap and can be held there by clamping, so that the sealing element is connected to the closure cap via the collar. The sealing element is preferably held in a clamping manner via a flanged edge.

To connect a delivery device, an injection cannula or a mandrel of the delivery device can be attached to the outside of the sealing element in order to pierce the sealing element. In this case, the sealing element is pushed aside, the annular collar remaining on the associated holding device of the closure cap and the sealing element thus being held in position on the closure cap. If the conveying device is again removed from the closure cap, the sealing element closes automatically, so that the opening of the closure cap is in turn sealed against liquid passage, in particular leakage of liquid out of the container. The sealing element is in a preferred Embodiment a reclosable sealing element. If necessary, the sealing element, in particular the sealing element for connecting a mandrel, can be slotted at least in sections or continuously.

In a second variant, the sealing elements of the connection devices can also be designed differently. One sealing element can be designed in particular for attaching an injection syringe, while the other sealing element is designed in particular for attaching a mandrel to an infusion set or the like. The sealing elements can thus be adapted in a special way, for example with regard to their thickness to be pierced, in order to enable an inexpensive connection of an injection syringe or an infusion set or the like.

The sealing element of the first connection device, which is used, for example, to remove a medical fluid by means of an infusion set, can be configured as described above for the first variant and in particular can have a sealing head that forms the outside and a sealing body that connects to the sealing head. The sealing body is connected to an annular collar via a circumferential circumferential flange and is held by the annular collar on a first holding device of the cap body. A connection of the sealing element to the cap body is thus established via the ring collar, so that the sealing element is held in position at the opening of the cap body via the ring collar. The sealing body is to be pierced, for example, by a mandrel of a conveying device, the sealing body being pushed aside when the mandrel is attached and inserted, the sealing element as a whole being held in position on the cap body of the closure cap over the annular collar.

In contrast, the sealing element of the second connection device can have a sealing head which forms the outside and a sealing body which adjoins the sealing head. In this case, the sealing body is not fixed to a holding device of the cap body by means of a circumferential ring collar connected via a flange, but is held directly to a second holding device of the cap body via an edge section. In this way, this second sealing element can be designed in particular for piercing by means of an injection cannula. Because such an injection cannula has a comparatively small cross-section, there is a smaller one when the injection cannula is inserted Deformation on the sealing element compared to the insertion of a mandrel, for example an infusion set.

In this variant, the sealing elements of the different connection devices can differ in particular in their thickness in order to adapt the connection devices to the different conveying devices. The second sealing element, which can be used to attach an injection cannula to an injection syringe, can in particular have a greater thickness than the first sealing element, which is adapted, for example, to attach a mandrel to an infusion set. The first sealing element preferably has a central thickness of 2 mm to 8 mm, preferably 3 mm to 6 mm. The second sealing element preferably has a central thickness of 2 mm to 8 mm, preferably 3 mm to 7 mm.

The sealing elements can have an at least approximately rotationally symmetrical shape. For example, the sealing head and the sealing body can each be at least approximately cylindrical, the outside of the sealing head, which points outwards, being convex.

In one embodiment, the underside of the first and / or the second sealing element, which provides the inside, is essentially flat. In the first sealing element, the top of the collar is lower than the top of the sealing head and / or the bottom of the collar is lower than the bottom of the sealing body. The first sealing element preferably has a total diameter of 8 mm to 14 mm, preferably 10 mm to 12 mm. The second sealing element preferably has a total diameter of 4 mm to 11 mm, preferably of 6 mm to 9 mm. In one embodiment, the sealing head of the first sealing element has a diameter of 4 mm to 10 mm, preferably from 6 mm to 8 mm and / or the sealing head of the second sealing element has a diameter of 2 mm to 8 mm, preferably from 3 mm to 6 mm.

Furthermore, the scope of the invention also includes a bottle which comprises a closure cap according to the invention described above. The bottle can be made, for example, using SBM (stretch blow molding) or BFS (blow fill seal). The bottle and the closure cap can be connected to one another in particular by means of clamping, gluing and / or welding. The bottle is preferably filled with an infusion solution.

1A-1C to 5A-5D show a first embodiment of a closure cap 2, which can be attached to a container 1, in particular in the form of a bottle, for example a plastic bottle or a glass bottle, to close the container 1 to the outside and to provide access for filling or removing a medical liquid .

The closure cap 2 is attached to a container body 10 of the container 1 and connected in a sealing manner to the container body 10, for example welded or glued.

The closure cap 2 has a cap body 20 which has two connection devices 3, 4 on an upper side 21 for connecting different conveying devices 5, 6 (see 3A and 3B ) having. The connection devices 3, 4 each have a sealing element 31, 41, which is received in a holding device 32, 42 in the form of a form-fitting receptacle on the cap body 20 and is held in a clamping manner on the holding device 32, 42. In particular, the holding devices 32 and 42 are each designed as a, preferably annular, flanged edge. The sealing elements 31, 41 serve to close openings 321, 421 on the upper side 21 of the cap body 20 to the outside, a sealing head 310, 410 of the sealing element 31, 41 projecting into the associated opening 321, 421 and sealingly sealing it . The sealing elements 31, 41 are inserted into the openings 321, 421 when the holding devices 32 and 42 are not initially bent over. To fix the sealing elements 31 and 42, the holding devices 32 and 42 are then, as for example in Figure 1C shown, bent.

The connection devices 3, 4 are in an initial state, shown in FIG 1A-1C , each covered by a break-off piece 30, 40 and closed to the outside in such a way that the openings 321, 421 with the sealing elements 31, 41 arranged therein are not accessible from the outside and are protected against contamination. The interior formed by the break-off piece 30, 40 is preferably sterile.

A first connection device 3 serves to remove a medical liquid from the container 1. In contrast, another, second connection device 4 serves to supply a medical liquid into the container 1. A medical liquid is removed as in FIG Figure 3B shown, via a conveyor 6 in the form of a removal device, for example formed by an infusion set, which has a mandrel 61 with a comparatively large cross-section and can be attached to the sealing element 31 of the associated connection device 3 with the mandrel 61. In contrast, the supply of a medical liquid takes place via a conveying device 5 in the form of an injection syringe, shown in FIG Figure 3A , which can be attached to the sealing element 41 of the assigned second connecting device 4 with an injection cannula 51 in order to pierce the sealing element 41.

Because the mandrel 61 of the removal device 6 has a comparatively large cross-section, the associated opening 321 of the connection device 3 is also comparatively large, and accordingly the basic shape of this has rotationally symmetrical sealing element 31 a sealing head 310 with a comparatively large diameter. The sealing head 310 of the first sealing element 31 preferably has a diameter of preferably from 5 mm to 9 mm and / or the sealing head 410 of the second sealing element 41 has a diameter of 3 mm to 6 mm.

In contrast, the opening 421 of the other, second connection device 4 is smaller, and accordingly the sealing head 410 of the second sealing element 41, which extends into the opening, has a comparatively small diameter.

Detailed, separate illustrations of the sealing elements 31, 41 are shown in Figures 4A-4D and 5A-5D shown.

The first sealing element 31 has a sealing head 310 with an outwardly facing, convex outer side 311. A sealing body 312 adjoins the sealing head 310 - on the rear of the outer side 311 - and is connected via a circumferential flange 313 to a circumferential circumferential collar 314. The sealing element 31 lies in an opening 320 of the holding device 32 via the annular collar 314 and is held in a clamping manner on the holding device 32. An underside 315 of the sealing element 31 points into an interior 20 of the closure cap 2 (see, for example, Figure 3A ). The underside 31 of the first sealing element 31 is essentially flat here. In the first sealing element 31, the top of the collar 314 is lower than the outside or top 311 of the sealing head 310. In addition, the bottom of the collar 314 is lower than the inside or bottom 315 of the first sealing body 31. The collar 314 thus extends over the bottom 315 out.

The other, second sealing element 41 likewise has a rotationally symmetrical shape and consists of a sealing head 410, to which a cylindrical sealing body 412 connects to the rear of a convexly curved outer side 411. Via this cylindrical sealing body 412, the sealing element 41 is fixed directly in an opening 420 of the assigned, second holding device 42, in that an edge section 413 of the sealing element 41 is held in a clamping manner in the opening 420 of the holding device 42. An underside 414 of the sealing element 41 points towards the interior 200 of the closure cap 2. The underside 414 of the second sealing element 41 is essentially flat here.

The maximum thickness - viewed along an attachment direction A, in which a conveying device 5, 6 is to be attached to a respectively assigned sealing element 31, 41 (please refer 3A and 3B ) - of the first sealing element 31, measured between the outside 311 and the inside 315, is smaller than the maximum thickness of the other, second sealing element 41, again measured between the outside 411 and the inside 414. The different shape in diameter and thickness is thereby requires that when a mandrel 61 is attached, as in Figure 3B shown, the associated, first sealing element 31 is to be pushed aside to a much greater extent than when attaching an injection cannula 51 to the associated, second sealing element 41. The first sealing element 31 can thus be pierced and displaced in a favorable manner when a mandrel is attached. The same applies to the second sealing element 41 when an injection cannula 51 is attached.

Both sealing elements 31, 41 close again automatically when the respectively assigned conveying device 5, 6 is again removed from the connecting device 3, 4.

Because the sealing elements 31, 41 are convexly curved on their outer sides 311, 411 and also protrude outwards beyond the upper side 21 of the cap body 20, the sealing elements 31, 41 can be dabbed or wiped off in a favorable manner for the purpose of disinfection, as may be the case may be dictated by legal requirements. In particular, the shape of the sealing elements 31, 41 on their outer sides 311, 411 can ensure that the outer sides 311, 411 can be reached by a suitable disinfection tool, for example a swab or a wiping cloth, the convex curvature additionally ensuring that that a disinfectant liquid or other residues do not remain on the outside 311, 411 after dabbing or wiping, but instead the sealing element 31, 41 can be wiped off in a favorable manner. The central region of the sealing head 310 preferably has a thickness which is 0.1 to 1 mm greater than the edge region of the sealing head 310. The center of the convex region (see also FIG Figures 4B and 5B ) is 0.1 to 1 mm, preferably 0.3 mm to 0.7 mm, above the outer edge.

The basic procedure for attaching a conveyor device 5, 6 to an associated connection device 3, 4 is as follows.

In an initial state, the closure cap 2 connected to the container 1 is present with break-off pieces 30, 40 arranged thereon. The break-off pieces 30, 40 are formed integrally with the cap body 20 and over circumferential predetermined breaking points 300, 400 connected to the cap body 20 such that the outer sides 311, 411 of the sealing elements 31, 41 are covered towards the outside.

If a conveyor device 5, 6 is to be attached to an associated connection device 3, 4, the respective break-off piece 30, 40 is removed from the cap body 20 by a user gripping the break-off piece 30, 40 between his fingers and from the cap body 20 along the predetermined breaking point 300, 400 breaks off. In this way, the respective sealing element 31, 41 is exposed, so that the conveying device 5, 6 can be attached to the outside 311, 411 of the sealing element 31, 41 (see 2A to 2C ).

The sealing element 31, 41 is now pierced by means of a suitable piercing tool, so that a flow connection is created between a body 50, 60 of the respective conveying device 5, 6 and the interior of the container 1, so that a medical liquid is filled into or out of the container 1 can be removed from the container 1.

With its cap body 20, the closure cap 2 can preferably be made of plastic, for example by means of plastic injection molding. The break-off piece 30, 40 of the connection devices 3, 4 are initially formed in one piece with the cap body and can be broken off from the cap body 20 in order to access one of the sealing elements 31, 41.

While the cap body 20 is made of a comparatively rigid plastic material, the sealing elements 31, 41 are made of a comparatively soft, elastic material, for example polyisoprene or a thermoplastic elastomer.

At one in 6A-6C and 7A-7C The illustrated embodiment of a closure cap 2 has the connection devices 3, 4 identical sealing elements 31, 41, which are arranged in a clamping manner in holding devices 32, 42 of identical construction. The shape of the sealing elements 31, 41 corresponds to that in FIG 4A-4D shown execution.

Again, a connection device 3 serves to remove a medical liquid from a container 1 connected to the closure cap 2, while the other connection device 4 serves to fill in a medical liquid.

A delivery device 5 in the form of an injection syringe with an injection cannula or a delivery device with a mandrel can be used here both for removal and for filling.

Otherwise, the embodiment is in accordance with 6A-6C and 7A-7C identical to the embodiment described above, so that reference is made to the above statements.

The idea on which the invention is based is not limited to the exemplary embodiments described above, but can in principle also be implemented in completely different embodiments.

Due to the fact that the outward-facing outer side of the sealing elements is convex and protrudes outwards over a front side of the cap body of the closure cap (when the break-off pieces of the connection devices are removed), the outer side of the sealing elements can be disinfected more easily and effectively be wiped or dabbed off.

In principle, a closure cap can also have only one connection device with a sealing element or more than two connection devices, each with a sealing element.

It is also fundamentally conceivable that only one sealing element of several sealing elements of several connection directions is convexly curved on its outside.
