Embodiment Construction

[0061] Figure 1 to Figure 13 Shown is a neck 1 of a container having a longitudinal axis A and comprising a mouth wall 2 from which threads 3 project transversely. The thread 3 comprises a beginning portion 4 closer to the container opening 5 and a final portion 6 further away from said opening 5 . A beginning portion 4 and a final portion 6 are arranged at both ends of the helical path defined by the thread 3 . The final portion 6 comprises a first abutment face 7 arranged transversely with respect to the outer surface 8 of the mouth wall 2 . In particular, the first abutment face 7 may lie on a plane passing through the longitudinal axis A and may be substantially perpendicular to the outer surface 8, as figure 2 shown in . Alternatively, the first abutment face 7 may lie on a plane inclined with respect to the longitudinal axis A. As shown in FIG. In particular, the first abutment face 7 may be shaped so as to define an inclined plane or cam profile which interacts wi...

Abstract

Container means comprises neck means (1) provided with thread means (3)on which cap means (5; 22; 25; 35) can be screwed as well as contrast means (6; 6a) for interacting with opening indicating means (11; 23; 26; 30; 39) of said cap means (5; 22; 25; 35), said contrast, means (6; 6a) being provided along helix means of said thread means (3); cap means comprises thread means (38; 138) suitable for interacting with further thread means (3)of neck means (1) of a container, and opening indicating means (39; 401) provided with stop means (600), said stop means (600) being provided along helix means of said thread means (38; 138).

Description

technical field [0001] The invention relates to closure means comprising container neck means and cap means having opening indication means arranged to interact with said neck means. Background technique [0002] Containers are known comprising a neck arranged to receive a cap and having an opening defined by a side wall externally threaded. Protruding from the side wall is an annular projection extending circumferentially relative to the neck and arranged further from the opening of the container relative to the threads. [0003] The cap has a cylindrical skirt comprising a first portion cooperating with the bottom wall to define the cap base and a second portion comprising a seal adapted to inform the user of the integrity of the product contained in the container. Turn on the indicating device. The tamper indicating device has a tamper evident ring interacting with the aforementioned protrusion. [0004] The first part and the second part are separated by a predetermin...
