This invention is an improvement to be applied to certain known bottle openers, called automatic bottle openers, in which, in order for the extraction to take place it is essential that the closure (29) offers sufficient friction on the worm (16). Otherwise, once the worm has penetrated the closure, at the point of extraction, it can unthread itself from the closure by means of an anti-clockwise rotary movement and the perforated closure remains inside the neck of the bottle (28). The invention solves the disadvantage and is characterised in that; if the friction of the closure (29) on the worm (16) is not sufficient, a mechanical system takes over automatically that stops the worm only in anti-clockwise rotary motion during the single extraction stage to then, in the process of the same upward movement, allow the restoration to anti-clockwise rotation so that that the worm (16) can be released from the closure (29).
L~invention est une amélioration apportée à certains ouvre-bouteilles connus, dénommés ouvre-bouteilles automatiques, pour lesquels l~extraction nécessite un contact frottant suffisant du bouchon (29) sur la vis sans fin (16). Dans le cas contraire, une fois que la vis sans fin a pénétré dans le bouchon, elle risque, au moment de l~extraction, de se dévisser du bouchon par rotation dans le sens inverse des aiguilles d~une montre en laissant le bouchon perforé à l~intérieur du goulot de la bouteille (28). Pour remédier à cet inconvénient, l~invention est caractérisée en ce que, si le contact frottant du bouchon (29) sur la vis sans fin (16) est insuffisant, un système mécanique se déclenche automatiquement pour bloquer la rotation de la vis sans fin dans le sens inverse des aiguilles d~une montre au cours de l~extraction et, lors de l~opération de traction vers le haut, permet à nouveau la rotation de la vis sans fin (16) dans le sens inverse des aiguilles d~une montre pour qu~elle puisse être retirée du bouchon (29).
