Abstract (en)
The closure cap comprises a conventional capsule (1) that is threaded on the bottle-neck (2) and incorporates a disk (4) of flexible material placed in the bottom of the capsule constituting a means of leak-proof closing at the bottle mouth when the same capsule (1) is pressed over the bottle thread. On tightening and corresponding pushing of the disk (4) over the bottle mouth, a perimetric adaptation of the disk edge is produced over the mouth side due to the said disk diametre being slightly greater than that of its housing capsule.
