Embodiment Construction

[0073] refer to Figures 1 to 4 , has shown a cap 1 comprising a cylindrical skirt 2 delimiting a lateral surface 3 of a body 4 of the cap 1 and an opening indicator ring 5 .

[0074] The cap 1 can be made from plastic material by compression forming or by injection moulding.

[0075] A plurality of through cuts or openings are obtained in the cylindrical skirt 2 defining the nominal opening line 13 of the cap 1 .

[0076] Between adjacent through-slits are defined bridge elements arranged to connect the main body 4 to the closure indicator ring 5, these bridge elements being adapted to be disconnected when the cap 1 is opened for the first time.

[0077] In the body 4 is obtained a thread 6 suitable for engaging with a corresponding further thread 7 obtained in the neck 8 of a container 9 capable of being associated with the cap 1 .

[0078] Open indicator ring 5 is provided with one or more fins 10 protruding from its outer edge 11 .

[0079] The fins 10 are arranged to i...

Abstract

Cap means comprises opening-indicator means (5) that has an outer edge (11) wherefrom leads away fin means (10) which in use extends towards the inside of said cap means (1), said fin means (10) comprising, in one of its portions nearest said edge (11), an elongated element (14) having a substantially rectilinear extension, said fin means (10) further comprising, in one of its portions further awayfrom said edge (11), a flexible appendage means (18); cap means comprises opening indicator means (5) that has an outer edge (11) wherefrom leads away fin means (10) comprising a first portion (26) suitable for interacting with a surface (25) of first collar means (22) extending radially from a neck (8) of container means (9), a second portion (33) suitable for interacting with a further surface (27) of second collar means (23) extending radially from said neck (8) and a third portion (39) suitable for interacting with a yet further surface (40) of said first collar means (23).

Description

technical field [0001] The present invention relates to a cap mechanism capable of being associated with a container, in particular a cap mechanism having open indicator means comprising a safety ring mechanism and a fin mechanism arranged to interact with the neck of the container. Background technique [0002] The known cap consists of a cylindrical skirt comprising a first part cooperating with the bottom wall to define a closure element capable of being associated with the container, and a second part constituted suitable for informing the user of what is in said container. Open indicator device for integrity of packaged product. [0003] The aforementioned second part comprises a ring adapted to interact with a protrusion obtained on the neck of the container. [0004] The first part and the second part are separated by a nominal opening line formed by a plurality of cuts or openings and spaced through the cylindrical skirt and by further bridge parts extending between...
