Embodiment Construction

[0058] Referring to Figures 1 to 8, there is shown a neck 1 of a container comprising a side wall 24 defining an opening 25 of the container.

[0059] Formed on the side wall 24 is a thread 2 shaped in such a way as to engage with a corresponding further thread 3 on the inside of the cap 4 which must be connected to the neck 1 .

[0060] The cover 4 can be made by compression molding of plastic material, or by other known manufacturing processes.

[0061] The neck 1 is equipped with abutment means 5 projecting circumferentially from the side wall 24 and arranged to interact with opening indication means 7 provided by the lid 4 .

[0062] The opening indicating means 7 comprise a ring 8 connected to the base body 9 of the lid 4 by a bridge intended to break when the container is first opened.

[0063] The base body 9 is delimited by side skirts 26 and a bottom wall 27 .

[0064] Projecting from the end region of the ring 8 are flap means 10 which, in use, are arranged inside ...

Abstract

A cap comprises an opening indicating element provided with a flap arrangement suitable for interacting with an abutment arrangement associated with a neck of a container, said flap arrangement comprising at least one first portion and at least one second portion arranged alongside one another along a peripheral edge of said opening indicating element, a dimension of said at least one second portion measured transversely in relation to said peripheral edge being greater than a corresponding dimension of said at least one first portion measured transversely in relation to said peripheral edge; a container comprises a neck from which an abutment arrangement projects and a cap provided with a flap arrangement suitable for interacting with said abutment arrangement, said abutment arrangement comprising a plurality of distinct abutment elements and said flap arrangement comprising at least one portion suitable for being received in a gap defined between two abutment elements of said plurality of abutment elements. The invention also provides a seal device for inserting into the cap.

Description

technical field [0001] The invention relates to closure means comprising abutment means associated with the neck of a container and lid means provided with opening indication means provided with safety ring means and flap means arranged to interact with the abutment means . The invention also relates to sealing means which can be associated with the cap means and which are adapted to be arranged between the cap means and the mouth of the container neck. Background technique [0002] Caps are known which consist of a cylindrical skirt comprising a first part cooperating with the bottom wall to define the base of the cap and a second part constituting an opening indicator adapted to inform the user that the container is packaged Integrity of the product in. [0003] The second part includes a ring that interacts with a protrusion formed in the neck of the container. [0004] The protrusion is annular and protrudes from the side wall of the neck. [0005] the first part and...
