Abstract

An ampoule for a medical liquid comprises an ampoule body for accommodating a medical liquid and a connection part for connecting a removal device to the ampoule, which connection part extends in a longitudinal extension direction and adjoins the ampoule body. The connection part and the ampoule body are formed as one piece and the connection part has a threaded segment having at least two thread turns arranged thereon, which are axially offset from each other in the longitudinal extension direction. The ampoule enables simple attachment of a removal device, creates a tight transition between a connection part and the removal device, is simple and economical to produce, and can provide a defined attachment state for the removal device on the ampoule.

Claims

1. An ampoule for medical liquid, said ampoule being produced by means of a blow/fill/seal method, comprising

an ampoule body for receiving medical liquid,

a connection part, which extends along a longitudinal extension direction and connects to the ampoule body, for the sealing connection between a removal device with a Luer cone and the ampoule and

a break-off part which is realized integrally with the connection part and is connected to the connection part by means of a predetermined breaking point,

wherein the connection part is formed integrally with the ampoule body and comprises a threaded portion with at least two threads arranged thereon which are offset axially with respect to one another along the longitudinal extension direction.

2. The ampoule as claimed in claim 1, wherein the connection part comprises a longitudinal extension, in that with the removal device in a completely connected state the Luer cone of the removal device is situated in the connection part of the ampoule and does not extend into the ampoule body.

3. The ampoule as claimed in claim 1 wherein each thread comprises two thread portions which are arranged on diametrically opposite sides of the threaded portion.

4. The ampoule as claimed in claim 1, wherein the predetermined breaking point is provided exclusively by means of a ring predetermined breaking point which extends over the circumference of an opening in the connection part.

5. The ampoule as claimed in claim 1, wherein the break-off part comprises an identification in the form of an opening or embossing.

6. The ampoule as claimed in claim 1, wherein when viewed along the longitudinal extension direction, the break-off part does not protrude beyond the predetermined breaking point in the direction of the connection part.

7. The ampoule as claimed in claim 1, wherein the ampoule body comprises an oval form in cross section transversely to the longitudinal extension direction.

8. The ampoule as claimed in claim 7, wherein in cross section transversely to the longitudinal extension direction, the ampoule body comprises a width, measured along a width direction between connecting webs which are arranged on both sides of the ampoule body, for connection to other ampoules, which width is smaller or equal to a depth of the ampoule body that is measured along a depth direction transversely to the width direction.

9. The ampoule as claimed in claim 1, wherein on a side remote from the connection part, the ampoule body comprises a bottom which defines a standing area onto which the ampoule is able to be placed.

10. The ampoule as claimed in claim 1, wherein the connection part comprises an opening into which an injection cone of a removal device is sealingly insertable.

11. The ampoule as claimed in claim 10, wherein the opening is tapered conically along the longitudinal extension direction.

12. An apparatus comprising at least two ampoules, each ampoule as claimed in claim 1, wherein the at least two ampoules are integrally connected together by means of a connecting web.

13. The apparatus as claimed in claim 12, wherein the connecting web extends axially between the ampoule bodies of the two ampoules parallel to the longitudinal extension direction and an incision which points axially into the connecting web is arranged on at least one axial end of the connecting web.

14. The apparatus as claimed in claim 12, wherein the break-off parts of the ampoules, are arranged side by side, are connected together by means of the connecting web, and are not connected to one another.

15. An apparatus comprising the ampoule as claimed in claim 1 and a removal device having an injection cone which is arranged on an injection body, wherein the connection part of the ampoule comprises an opening into which the injection cone is sealingly insertable.
