Closure device comprising a hinged cap moulded in the closed position

A closure of the type comprising:

• a first piece defining a base part comprising a top opening;
• opening at opposite axial ends, and intended to be mounted on the neck of a threaded receptacle, wherein said base bottom opening is defined by an annular wall from which an external skirt substantially perpendicularly projects and cooperates with the thread on the receptacle neck and the base top opening is defined by a funnel;
• and
• a second piece defining an annular ring connected to the base part and a cover associated with the annular ring by a joining and hinging device, wherein the cover is able to be moved with respect to the annular ring between an open position and a closed position, wherein when the cover is located over the funnel of the base in the closed position, the cover and the funnel cooperate to provide a closed and impermeable space therebetween;
• wherein the joining and hinging device is in the form of at least one strap which includes a first end connected to the annular ring and a second end connected to the cover;
• tamper-evident means between the annular ring and the cover, the tamper-evident means comprising an element connected on the one hand to the ring and on the other hand to the cover, said element being arranged so as to be deformed and broken when the cover is first opened, the element then being separated into a first part having a first end attached to the ring and a free second end and a second part having a first end attached to the cover and a free second end, the function of the arrangement of said element and said plug being to move the two free ends away from one another so that, when the cover is once again in the closed position, there exists between said two free ends a sufficiently great distance to be easily detected by a user;
• wherein the arrangement of the strap, the base part and the part forming the cover are connected to one another and the cover is in the closed position, the space between the external face of the cover and the opposite face of the strap is of sufficiently large dimension to facilitate removal of liquid in which the closure has been immersed or which has been sprayed on the closure.
