Problems solved by technology

Moreover, the groove tooth formations formed on the safety ring and the bottle neck, respectively, remain engaged "top-to-top", which causes radial expansion of the ring which may lead to elastic deformation of the ring
it's very unsightly
Furthermore, the serrations formed on the threaded bottle neck protrude radially outwards and may be damaged during operations such as those performed prior to filling the bottle, which reduces the effectiveness of the safety ring

Embodiment Construction

[0023] figure 1 The container 1 shown in FIG. 3 is a bottle whose neck 2 is formed integrally with the main part 3 of the bottle 1 . The neck 2 is formed with an external thread 4 .

[0024] x 2 Denotes the central axis of the neck 2, which is an axis of rotational symmetry of the neck 2, regardless of the fact that the thread 4 is inclined. 2a denotes the opening of the neck 2, ie the disk-shaped surface forming the boundary between the interior of the neck 2 and the exterior surface of the container 1.

[0025] The neck 2 is formed with a substantially truncated plane 5a defined in a direction converging towards the opening 2a and a plane substantially parallel to the axis X 2 Outer flange 5 between vertical annular surfaces 5b. P 5 Denotes the geometric plane of the surface 5b, which is aligned with the axis X 2 vertical.

[0026] According to the invention, the surface 5b is formed with crenellations / teeth or grooves 6 extending in the direction of the lower edge 7 ...

Abstract

The invention concerns a device comprising a closure cap (11), including a base (12) and a skirt (13) with an internal thread (14) adapted to co-operate with an external thread (4) of the neck (2) to be closed, and a tamperproof ring (16), linked by frangible means (17) to the skirt (13) and provided with notches (19) designed to co-operate with complementary notches (6) provided on the neck (2). The notches (19) of the ring (16) are oriented towards the base (12) of said closure cap (11), while the notches (6) of the neck (2) are oriented opposite to its outlet (2a).

Description

technical field [0001] The invention relates to a device for closing a container having a screw neck, a screw neck which can be closed by such a device and a container comprising such a neck which is closed by this device. Background technique [0002] In the field of liquid packaging, it is known to provide a closure to the threaded neck of a bottle, said closure comprising a safety ring / anti-movement ring ( tamperproof ring) bottle cap. Thus, unscrewing the cap necessarily results in a disconnection of the connection between the cap and the ring. It is known, for example, from EP-A-0330964 to provide such a safety ring with notches towards the center of the bottle neck and designed to cooperate with corresponding notches formed on the outer diameter surface of the bottle neck. By tightening the cap the said closing device is in place and then the notch formation of the safety ring is opposed to the notch formation formed on the neck of the bottle, in order to position th...
