<p>The presented patent application generally refers to the field of threaded taps for containers, particularly to taps of relatively small diameter from man-made material, which are used for the sealing of containers for storing content under pressure, generally sparkling drinks, beer and other food products containing carbon dioxide. Following the presented solution the protective-sealing ring (26) consists of an upper (30), and a lower surface (31), an external surface (32) and an internal one (33) which is the starting point of an internally looking radial ring (34). The latter is connected to the lower, inclined surface (35) and the upper, radial surface (36) while the earlier mentioned surfaces (35, 36) meet in the area of a flexible thin cross section (37). The internal surface (33) and the upper one (36) form a ring shaped notch (38) for the reception of a number of extensions (39) which are bent towards the outside when the locking element (11) is placed on the container element (12). The extensions (39) are relatively rigid, inflexible and are suitable only for rotational movement against the ring (26) more precisely around the axis through the area of thin cross section (37). The shown type features extensions (39) of almost rectangular cross section, including free terminal surfaces (40), the first and second side surfaces (41 and 42) as well as the second terminal surface (43) whose surface (42) enacts via the rounded off edge (44).</p> |
