DETAILED DESCRIPTION

(11) FIGS. 1 and 2 show a first illustrative embodiment of the closure cap according to the invention in a plan view and a bottom view, while FIGS. 3 to 5 show the closure cap in sectional views, wherein an additive is injected using an injection syringe or a liquid is withdrawn using a spike. Apart from the pierceable membranes, the closure cap is a one-piece plastic component that can be produced inexpensively in large numbers.

(12) The closure cap 1 has a lid part 2 and an edge part 3. The lid part 2 has a flat inner portion 4, from which an outer portion 5 protrudes outward. The outer portion 5 of the lid part 2 has an elongate shape with two substantially rectilinear portions 5A, which are adjoined at both sides by substantially semicircular portions 5B. The outer portion 4 extends across the whole width of the inner portion 4 of the lid part 2. A first injection part 6, a second injection part 7 and a withdrawal part 8 are located on the top of the outer portion 5 of the lid part 2 in a manner easily accessible to the user. The first injection part 6 is used for injection of an additive using an injection syringe that has a needle (FIG. 3), while the second injection part 7 is used for injection of an additive using a needleless injection syringe (FIG. 4). The withdrawal part 8 is used for withdrawal of liquid using a spike (FIG. 5).

(13) The two injection parts 6 and 7 and the withdrawal part 8 are arranged lying close to one another in a row on the outer portion 5 of the lid part 2. They lie on an axis 9 that corresponds to the longitudinal axis of the outer portion 5 of the lid part 2. The two injection parts 6 and 7, which have a smaller diameter than the withdrawal part 8, are arranged lying closely next to each other, while the withdrawal part 8 lies close to the two injection parts 6, 7.

(14) The two injection parts 6, 7 and the withdrawal part 8 are described below in more detail with reference to FIGS. 3 to 5.

(15) The first injection part 6, arranged on the outer edge of the lid part 2 and designed for injection of an additive using an injection syringe (FIG. 3) that has a needle, comprises an outwardly directed annular shoulder 10, which encloses the injection site. The annular shoulder 10 is closed with a break-off part 11, which adjoins the upper end of the annular portion 10 via an annular break-off zone 12 (FIGS. 4 and 5). The break-off part 11 has a round cap 13, to which a grip tab 15 is adjoined via a narrow web 14, which grip tab 15 extends across the outer portion 5 of the lid part 2 and downward as far as the edge part 3 of the closure cap 1.

(16) From the annular portion 10 of the first injection part 6, a closure part 16 is directed inward and has a recess 17. A pierceable, self-sealing membrane 18 is fitted in the recess 17 of the closure part 16. The membrane 18 is secured with a snap-fit in the recess 16. The recess 16 has an upper cylindrical portion 16A, which adjoins the annular portion 10 of the first injection part 6. The upper cylindrical portion 16A is adjoined by a lower cylindrical portion 16B, which has a greater internal diameter than the upper cylindrical portion 16A. The self-sealing membrane 18 accordingly has a lower cylindrical portion 18A with a greater external diameter, which sits in the lower cylindrical portion 16B of the recess 16. The lower cylindrical portion 18A of the membrane 18 is adjoined by an upper cylindrical portion 18B with a smaller external diameter, which sits snugly in the upper cylindrical portion 16A of the recess 16.

(17) To fix the membrane 18 with a clamping action in the recess 17, the closure part 16 has an inwardly projecting edge 19 at the lower end of the closure part 16 that engages under the membrane 18. The membrane 18 has a flat top and bottom and is not slotted. This means that, when the needle of an injection syringe has been pulled out, the membrane reliably seals again and no liquid escapes.

(18) The second injection part 7, arranged centrally, has an outwardly directed connector part 20 for the connection of a needleless Luer lock syringe (FIG. 4). Otherwise, the second injection part 7 does not differ from the first injection part 6. The connector part 20 of the second injection part has a conical recess 20A, for sealingly receiving the conical stem of the syringe, and an outer thread 20B. The conical recess 20A and the outer thread 20B are designed in such a way that a commercially standard Luer lock syringe can be attached to the connector part.

(19) The connector part 20 is closed with a break-off part 21, which is attached to the upper end of the connector part via an annular break-off zone 22. The break-off part 22 has a round cap 23 which is adjoined, via a narrow web 24, to a lateral grip tab 25, which extends outward across the outer portion 5 of the lid part 2 and as far as the inner portion 4 of the lid part 2.

(20) The second injection part 7 also has a closure part 26, which corresponds to the closure part 16 of the first injection site 6. The closure part 26 of the second injection site again has a recess 27, in which a membrane 28 is fixed with a clamping action. The closure part 26 of the second injection part 7 differs from the closure part of the first injection part 6 in terms of the membrane 28, which has a lower annular portion 28A adjoined, via a central web 28B, to an upper plate-shaped portion 28C, which has a cup-shaped depression 28D. The plate-shaped portion 28C of the membrane 28 is provided with one or more slits, for example being slotted crosswise.

(21) The withdrawal part 8 of the closure cap 1 has an outwardly directed connector part 29 for the attachment of the spike of an infusion appliance (FIG. 5). The connector part 29 has a recess 30 into which the spike of the infusion appliance is inserted. The recess 30 has an upper conical portion 30A and a lower cylindrical portion 30B, wherein the upper conical portion serves to center the spike, and the lower cylindrical portion serves to receive the spike sealingly. The recess 30 of the connector part 29 is closed with a break-off part 31, which is attached to the upper end of the connector part via an annular break-off zone 32. The break-off part 31 again has a lateral grip tab 33 which, like the grip tab of the break-off part of the first injection part, protrudes outward across the outer portion 5 of the lid part 2 and extends as far as the edge part 3 of the closure cap 1.

(22) The withdrawal part 8 has an inwardly protruding closure part 34 with a recess 35, in which once again a pierceable, self-sealing membrane 36 is fixed with a clamping action. The self-sealing membrane 36 of the withdrawal part 8 has an outer annular upper portion 36A, to which a plate-shaped lower portion 36C is adjoined via a central web 36B. The central web 36B of the membrane 36 is held and clamped by an inwardly protruding edge 37 at the lower end of the closure part 34.

(23) At the lower edge of the edge part 3, the closure cap 1 has a bead-shaped edge 38, which has a circumferential groove 39 on the underside. The closure cap can be fitted onto a bottle, wherein the upper edge of the bottle neck engages in the groove 29 of the bead-shaped edge 38 of the closure cap 1.

(24) FIG. 8 shows a bottle 40, in particular an SMB bottle, which is closed with the closure cap 1 according to the invention. The closure cap 1 sits securely on the bottle neck 41 of the bottle 40, which is filled with an infusion solution for example. Since the bottle neck is not closed in the head area and is instead open, the liquid is in direct contact with the cap. It is therefore possible to inject a medicament using a needleless injection syringe or using an injection syringe with needle. The closure cap can be designed as a screw cap, which is screwed onto the bottle neck of the bottle. However, it is also possible to weld the closure cap to the bottle neck.

(25) The handling of the closure cap 1 is described below.

(26) To withdraw a liquid, for example an infusion solution, the break-off part 31 is broken off from the closure cap 1, such that the membrane 36 of the withdrawal part 8 is exposed. The spike of the infusion appliance is then attached to the connector part 29 of the withdrawal part 8 (FIG. 5). If a medicament is to be injected using an injection syringe with needle, the break-off part 11 of the first injection part 6 is broken off, such that the membrane 18 of the first injection part can be pierced by the needle of the syringe. In doing this, however, the second injection site remains protected by the associated break-off part (FIG. 3). If a medicament is to be injected using a needleless injection syringe (Luer lock syringe), the break-off part 21 of the second injection part 7 is broken off, whereupon the Luer lock syringe can be screwed onto the connector part 20 of the second injection part 7 (FIG. 4).

(27) FIGS. 6 and 7 show an alternative embodiment of the closure cap 1 according to the invention, which differs from the closure cap described with reference to FIGS. 1 to 5 only in terms of the arrangement of the two injection parts and of the withdrawal part on the outer portion of the lid part. Therefore, the same reference signs are also used for the parts that correspond to each other. In the embodiment in FIGS. 6 and 7, the outer portion 5 of the lid part 2 of the closure cap 1 has a substantially rectangular shape with rounded corners. The two injections parts 6, 7 and the withdrawal part 8 are arranged offset in relation to one another on the top of the upper portion 4 of the lid part 2. The first injection part 6 and the withdrawal part 8 lie on one half, and the second injection part 7 on the other half, on the top of the outer portion 5 of the lid part 2. The grip tabs 15, 25, 33 of the injection parts 6, 7 and of the withdrawal part 8 are directed radially outward. They extend outward across the outer portion 5 of the lid part 2 and reach downward as far as the edge part 3 of the closure cap 1. The individual accesses are identified as injection parts or withdrawal part by the upwardly or downwardly directed arrows 42 on the grip tabs 15, 25, 33 of the break-off parts 11, 21, 31.

(28) Finally FIG. 9 shows a zoom of an illustrative embodiment of the injection part 7 with a hollow body 100 for piercing the membrane 28. In this embodiment upon connection of a syringe to the closure cap, the membrane 28 is pressed onto the point 102 or tip 102 of the hollow body 100 which is arranged below the membrane 28. In this embodiment, the point 102 of the hollow body 100 is not at a distance from the membrane 28 but rather is directly therebelow, preferably in contact with the membrane 28. In a non-shown embodiment the hollow body 100 is at a distance from the membrane 28, i.e. not in contact. Due to the hollow body 100 the reliability of the membrane opening and/or membrane closing is enhanced.

(29) Preferably the hollow body 100 for piercing the membrane 28 upon connection of the syringe is integrally formed on a disk-shaped body 101 which sits together with the membrane 28 in the recess 27 of the lid part 2 of the closure cap. The membrane 28 and the hollow body 100 together with the disk-shaped body 101 are held clamped in the recess 27 by a projecting, encircling extension 105 which engages under the disk-shaped body 101. In this case, the lower portion 28A of the membrane 28 is supported in the recess 27 of the lid part 2 of the closure cap by means of an upper, projecting extension 106 and the disk-shaped body 101 is supported therein by means of a lower, projecting extension 106. However, it is also possible to adhesively bond or to weld the disk-shaped body to the lid part 2 of the closure cap. In one embodiment the projecting, encircling extension 105 is provided as a beading flange.
