Abstract

The invention relates to a plastic ampoule which comprises a container (12) for receiving a defined field. Said container is provided with a neck (14) that can be closed by means of a head (16), the neck comprising a channel-type entrance port (24) for air to be interior (26) of the container (12). The aim of the invention is to improve the generic ampoule types in such a manner that the fluid can be safely stored and the syringe or needle base is reliably filled at any speed of withdrawal by means of the syringe or needle base. For this purpose, the entrance port (24) for air consists of at least one ring channel (28, 30) that is at least partially disposed on the outer and/or inner periphery of the neck (14).

Claims

1. Plastic ampoule with a container part (12) for holding a definable fluid, which is provided with a neck part (14) which can be sealed by a head part (16) and which has a channel-like entry point (24) for air into the interior (26) of the container part (12), characterized in that the entry point (24) for air consists of at least one annular channel (28, 30) which is configured at least partially on the outer and/or inner circumferential side on the neck part (14).

2. The ampoule as claimed in claim 1, wherein the respective annular channel (28, 30) is configured helically on the neck part (14) over a definable thread distance.

3. The ampoule as claimed in claim 2, wherein the helical annular channel (28, 30) has an inlet point (32) and an outlet point (34).

4. The ampoule as claimed in claim 2, wherein the profile shape of the annular channel (28, 30) is configured metrical or trapezoidal or in the form of a Whitworth thread.

5. The ampoule as claimed in claims 1, wherein the respective annular channel (28, 30) with its groove-shaped recess is interrupted at least partially by way of longitudinal bridges (38) which are positioned in the mold plane (40) of the container part (12).

6. The ampoule as claimed in claims 1, wherein on the outer circumferential side on the neck part (14) and outside of the respectively assigned annular channel (28) there is a stop part (26) as protection against stripping.
