<p>Of the type that incorporates a basic body (1) to which a support arm (5) is connected at its ends by means of a joint, while in its middle area a helicoidal spike (3) in the form of a ringlet is also connected by means of a joint. This spike may be coupled axially with the stopper, operating the bottle-opener as a unit. It centres its characteristics on the fact that in the fluted interior of the said support arm (5) there is one or more rockers (13-18), which tilt upon respective axes (14) and (19) and which are governed by retractile supports (16) and (21), in such a way that the bottle-opener offers the user, in addition to the fixed and conventional support upon the mouth or neck of the bottle defined by the free end (5') of the said arm, two further intermediate points of support (16) and (21), which may be used selectively and successively, employing throughout the stopper extraction operation the most suitable point of support at each moment. <IMAGE></p> |
