DESCRIPTION:
BRIEF SUMMARY
DESCRIPTION
As is seen in FIG. 1, the rigid skirt portion 2 also includes a second annular projection or flange 13 which projects inward (internal to the central aperture) in a radial direction;. The flange 13 is enclosed in an annular perimetrical groove of the rubber portion 3.
1. Technical Field
The invention relates to a security closure for containers. Specifically though not exclusively the closure is applied in the diagnostic field for practically and swiftly carrying out analyses of samples of substances. In particular reference is made to a closure of the type comprising a cap for closing a container, having a rigid skirt portion with a central aperture and a pierceable portion mounted in the central aperture; the pierceable portion is made of a material able to be pierced by a needle and is destined so to be pierced for injection of a substance into the container; a first security ring is connected by frangible means to the skirt portion such as to detach or distance from the skirt portion following a raising of the cap in an axial direction to the container; a cover is mounted removably on the cap in such a way as to cover the pierceable portion and prevent an introduction of a needle into the container; a raising of the cover leads to an uncovering of the pierceable portion of the cap, enabling a needle to be inserted into the container.
2. Background Art
The prior art teaches a cap for closing a container and provided with at least a portion made of a material able to be pierced using a needle; a cover is mounted on the cap in such a way as to cover the pierceable portion. The cap is screwed on the container and the cover is press-applied on the cap. In use, the cover is removed and the container, previously filled with a chemical reagent, is pierced so as to introduce an analytical sample therein, with a resulting mixture of the sample and the reagent. Thus the analysis can be performed by simple observation, without having to open the container. The injection is carried out by pushing the needle of a syringe through the pierceable portion of the cap.
In such known-type closures there is no guarantee that the container has not been tampered with before use: a miscreant could indeed remove the cover, and using a syringe introduce some substance or other capable of altering the reagent's properties, thereafter re-closing the cover and leaving no trace of fraud.
EP 0457107 discloses a closure cap for infusion or transfusion bottles having a pierceable stopper for the bottle neck and a cap gripping round the underneath of the bottle neck and over the stopper by sprung individual tongues. A slide ring secures the cap in gripping position. A tear-off strip, formed by an annular surface is positioned in the middle of the top of the cap. A closure of the type in object is disclosed by DE 4228090, wherein the cover is interposed between the pierceable portion and the rigid skirt portion of the cap; the cover is provided with a pull-ring, which lifts the detachable portion of the cover to detach it from the rest of the cover.
A drawback of this closure is that it is constructionally complicated and costly to manufacture and is non-practical to use.
DISCLOSURE OF INVENTION
The main aim of the present invention is to obviate the above-mentioned drawback of the prior art by providing a closure of the above-described type which is able to attest to any fraudulent intervention on the closure to which it is applied.
An advantage of the closure is that it is constructionally simple and economical and simple and practical to use.
The above aims and advantages are all attained by the closure of the invention, as it is characterized in the appended claims.
Further characteristics and advantages of the present invention will better emerge from the detailed description that follows, of an embodiment of the invention, illustrated in the form of a non-limiting example in the accompanying drawings, in which:
FIG. 1 shows a partially-sectioned vertical elevation view of the closure of the invention.
