Embodiment Construction

[0018] FIG. 1 shows the outlet-side end of a syringe 1 on which a sealing cap 2 is mounted for outlet-side sealing. In a known manner, the syringe has a seal on its inlet side and a sealable piston inside it, which serves to expel the medium contained in the syringe. The syringe 1 is designed as a glass syringe, and the sealing cover 2 is preferably made of chlorobutyl rubber or other elastic materials with similar properties.

[0019] The sealing cap 2 is designed in the shape of a cup and has a cylindrical wall portion 3 which is open at its end facing the syringe and has a cover 4 at its opposite end, wherein the cover is provided in a known manner. Sealable outlet 5. A seal 6 is provided inside the lid. The sealing cover 2 is pushed apart along the direction of the arrow 7 and fitted on the outlet side end of the syringe 1, thereby sealing the syringe body.

[0020] At a predetermined distance from the outlet-side end, the syringe 1 is provided with a first locking elem...

Abstract

Syringe comprising a fluid medium holding barrel with a locking elements section and expansion sections on the outer surface and a sealing cap on the outlet of barrel, is new.

Description

technical field [0001] The present invention relates to a syringe, and more particularly to a syringe having a first locking element on the outer surface of the barrel, and a corresponding portion of the cover having, on its inner surface, a locking element for interacting with the first locking element. The syringe of the second locking element, thereby allowing the cap to be easily and sealed mounted on the syringe without damaging the syringe. Background technique [0002] Such a syringe is known from EP 0 723 784 A. The barrel has a circumferentially extending lug with a side inclined towards the outlet and a back shoulder substantially perpendicular to the circumferential direction. Inside the syringe, the cap to be fitted has a portion configured as a cutout extending in the circumferential direction, and after the cap has been pushed on, the cap snaps onto the protrusion of the syringe. Since the outer diameter of the projecting portion of the syringe is larger than...
