Problems solved by technology

[0014] Disadvantages of conventional closures include the use of very complex closures with multiple separate parts in order to provide a solution to prevent evaporation and contamination
These complex solutions have not been concerned with preventing contamination due to contact between the closure and the dispenser, but only with preventing contamination due to contact between the interior of the container and the environment
Prior art solutions also fail to provide container closures that allow the dispensing device to function without touching the container or closure

Abstract

The present invention concerns a closure for mounting on a reagent vessel, the closure comprising a main body comprising a hole to be mounted around the opening of a vessel, such as a reagent container, a top wall attached by its edges to the top edges of the main body, at least one incision dividing the top wall into at least two parts, a flange attached to and extending outwards from the top edge of the top wall, and a hinge area connecting the top edge of the main body to the flange and the top wall.

Description

technical field [0001] The present invention relates to a closure device for mounting on a reagent container, said closure device comprising a body containing an aperture to be mounted around an opening of a container such as a reagent container, a top edge attached to said body by an edge and at least one cutout dividing the top wall into at least two parts. Background technique [0002] In the prior art, reagent containers are usually closed with caps and closures developed to keep the contents of the container free from contamination or from evaporation. Many of the solutions contain pierceable septa. However, piercing these closures may result in contamination of both the dispenser and the container contents, because the piercing is usually performed with the edge of the dispenser needle, thus making the dispenser each time the dispenser is used. The dispensers will all come into contact with the closure. [0003] EP0542295 relates to a stopper fitted on the mouth of ...
