The invention relates to a medical hollow container, to such a medical hollow container having a closure cap, to a method for producing such a medical hollow container, and to a kit which comprises such a medical hollow container.
Medical hollow containers of the type discussed here are known. These generally cylindrically-shaped containers comprise a chamber for receiving the medical preparation, which chamber is delimited on both sides by a proximal and a distal end. The distal end, in particular with a distal opening, has a fastening structure, and the medical preparation can be removed from or introduced into the medicine container via the distal end. According to the design of the medicine container, individual distal closure devices for closing the distal end are arranged on the fastening structure, the distal closure device being adapted to the exact shape of the distal end of the given design of the medicine container. The proximal end is closed off by a portion of the inner wall of the base body, or has a proximal opening. The open proximal end is designed to receive a proximal closure device, in particular a stopper or a plunger. The plunger can be inserted into the proximal end, and the medical preparation can be expelled in the distal direction from the distal opening of the medical hollow container by a sliding movement of the plunger; or, in a reverse, proximal movement, a medical preparation can be drawn through this opening into the syringe.
Known medicine containers are typically in the form of a syringe, carpule, ampoule or injection bottle, i.e. a vial, can be made of glass or a plastics material, and typically have a base body with a central axis, the base body often being at least substantially rotationally symmetrical about the central axis. In this case, the base body encloses, at least in the circumferential direction around the central axis, a receiving portion which is designed to receive at least one medical preparation.
Syringes are closed in the direction of their proximal end with an axially, in particular distally and/or proximally displaceable closure device, which is typically designed as a plunger element operatively connectable to a plunger rod, in particular a sealing plunger element. By means of the plunger rod, it is possible, at least after the plunger rod has been operatively connected to the closing plunger element, to displace the closing plunger element in the distal and/or proximal direction and thereby dispense a medical preparation from the syringe and/or introduce it into the syringe.
Carpules, on the other hand, are closed with a stopper that does not protrude from the container, with no operative connection, in particular no screw connection, being provided between the stopper and a plunger rod. Instead, a separate dispensing device is provided for dispensing a medical preparation from a carpule, which at least partially penetrates the interior of the medicine container via the proximal opening and displaces the stopper into the base body of the carpule in such a way that the medical preparation is discharged at the distal end via a cannula which pierces a membrane-like closure.
Distal closure devices which have an injection device, in particular a cannula and/or a Luer lock fastening, can be fastened in particular to syringes. Vials, on the other hand, are not only intended for direct injection of a medical preparation, such that vials have a closure device at their distal end, which is designed, for example, as a stopper, cap or membrane closure. Similarly to vials, carpules typically have membrane-like closure devices which can be pierced with an injection needle or cannula.
A closure for a container for pharmaceutical preparations, and a container provided with this closure, are known from the German utility model DE 20 2018 102 680 U1. The closure for releasably closing an opening at the distal end of a cylindrical container for pharmaceutical preparations, in particular a syringe, preferably by means of a Luer lock fastening, comprises a cylindrical closure cap with a cylindrical cavity for receiving and holding a sealing element, the closure cap comprising an installation portion which points towards the container in the installed position, a sealing element with a sealing portion which is at least partially arranged inside the installation portion, and wherein the outer edge of the sealing element is set back from the outer edge of the installation portion. A device known as a Luer lock has become established in the medical field for fastening a cannula, for example, to a distal end of a container. In the case of containers made of plastic, this Luer lock attachment can be made as a single piece with the container. However, this is not possible in this way with medical hollow containers made of glass.
An apparatus for screwing media-carrying threaded connections, in particular Luer lock connections, is known from European patent EP 1 567 215 B1. The apparatus has an outer part and an inner part rotatably received therein, which has means for receiving the thread-bearing connecting part or an additional part secured against rotation to the same, wherein inhibiting means are present, which allow a rotation of the inner part relative to the outer part only in one direction of rotation, and oppose this rotation with a resistance.
German patent DE 603 14 018 T2 discloses a syringe arrangement for medical compositions, wherein at least one plunger element has a first stationary part, which has at least one flow passage, and a second displaceable part, which has at least one flow passage, wherein the first part and the second part are arranged side by side. In order to establish a flow connection between the two chambers, the flow passages are brought into alignment, in particular by turning. An anti-rotation function is provided in this case, wherein the first part of the plunger element preferably has an elliptical shape in order to provide such an anti-rotation function, and/or the first part of the plunger element has one or more grooves which can be brought into engagement with one or more corresponding ribs which are arranged on the inner surface of the syringe barrel. The first part is held in place as a result, while the second part can be rotated slightly.
The disadvantage of the prior art, however, is that when attaching a closure cap to a medical hollow container, in particular when rotating a closure cap onto a medical hollow container, the medical hollow container is at least partially rotated relative to the closure cap. As such, securing the closure cap on the medical hollow container is made more difficult.
The invention is based on the object of providing a medical hollow container, such a medical hollow container having a closure cap, a method for producing such a medical hollow container, and a kit which has such a medical hollow container, wherein the disadvantages mentioned do not occur and wherein in particular a rotation of the closure cap relative to the medical hollow container, in particular when the medical hollow container is closed by means of the closure cap, is at least largely prevented.

The medical hollow container is characterized in that the fastening portion has at least one rotation inhibiting structure which is designed to at least inhibit relative rotation between the medical hollow container and the closure cap with respect to each other, wherein the rotation inhibiting structure has at least one rotation inhibiting element, wherein the at least one rotation inhibiting element is at least one elevation and/or at least one depression, and/or is designed as a non-circular shape of the opening and/or a non-circular edge of the opening.
The medical hollow container of the present invention has advantages compared to the prior art. Advantageously, particularly when the hollow container is closed with a closure cap, a relative rotation of the closure cap with respect to the medical hollow container is at least inhibited, which enables the medical hollow container to be more easily closed with the closure cap. Advantageously, a rotational movement of the closure cap relative to the medical hollow container is at least inhibited or is completely prevented, in particular when a medical apparatus is arranged and/or fastened to the closure cap, in particular the closure cap designed as a coupling element.
