Abstract
Abstract A closure device for a recipient with a threaded neck. It includes a tapped closure having a lower part attached to a guarantee strip by a zone of connection of low mechanical resistance, the strip presenting an elastically-deformable, inner, annular bead adapted to clip beneath a holding flange formed on a lower periphery of the neck by forced screwing of the closure; and an outer peripheral boss axially separated from the bead by a zone of controlled elastic deformation, an upper face of the boss and a lower edge of a lateral wall of the closure having formed therein, respectively, at least one tooth and at least one notch, the tooth being intended to be temporarily received in the notch during screwing when the bead is in abutment with the holding flange in order to avoid any relative rotational displacement of the closure with respect to the strip and to ensure clipping without deteriorating the zone of connection.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
230 words
A closure device for a recipient with a threaded neck, comprising a tapped closure having a lateral wall and a lower part attached to a guarantee strip by a zone of connection with low mechanical resistance, said strip presenting an elastically deformable, inner, annular bead with a lower inner face inclined at an angle with respect to an axis of the closure, for clipping beneath a holding flange made on a lower periphery of said neck by forced screwing of the closure; and an outer peripheral boss on the strip wherein said outer peripheral boss is separated from said bead by a zone with controlled elastic deformation, wherein when screwing the closure, the deformation zone permits a bending and a conformance of a lower part of the strip relative to the axis of the neck until the inclined lower face of the bead becomes substantially parallel to said axis; and an upper face of the boss and a lower edge of the lateral wall of the closure have formed therein, respectively, at least one tooth and at least one notch, said tooth being temporarily received in said notch during screwing when said bead axially abuts the holding flange in order to preclude any relative rotational displacement of the closure with respect to the strip and to ensure clipping of the closure to the recipient without deteriorating the zone of connection.
Claim 2
Dependent Claim
230 words
A closure device for a recipient with a threaded neck, comprising a tapped closure having a lateral wall and a lower part attached to a guarantee strip by a zone of connection with low mechanical resistance, said strip presenting an elastically deformable, inner, annular bead with a lower inner face inclined at an angle with respect to an axis of the closure, for clipping beneath a holding flange made on a lower periphery of said neck by forced screwing of the closure; and an outer peripheral boss on the strip wherein said outer peripheral boss is separated from said bead by a zone with controlled elastic deformation, wherein when screwing the closure, the deformation zone permits a bending and a conformance of a lower part of the strip relative to the axis of the neck until the inclined lower face of the bead becomes substantially parallel to said axis; and an upper face of the boss and a lower edge of the lateral wall of the closure have formed therein, respectively, at least one tooth and at least one notch, said tooth being temporarily received in said notch during screwing when said bead axially abuts the holding flange in order to preclude any relative rotational displacement of the closure with respect to the strip and to ensure clipping of the closure to the recipient without deteriorating the zone of connection.
Claim 3
Dependent Claim
28 words
The device of claim 1 wherein the width of an upper face of the bead is at least equal to the width of the flange of the recipient.
Claim 4
Dependent Claim
21 words
The device of claim 1 wherein an upper face of the bead is substantially perpendicular to the axis of the closure.
Claim 5
Dependent Claim
27 words
The device of claim 1 wherein the zone with controlled deformation has an inner face with curvature and inclination with respect to the axis of the closure.
Claim 6
Dependent Claim
44 words
The device of claim 1 wherein a ratio between an inner diameter of the bead and an outer diameter of the neck beneath the flange is such that, after clipping, a lower part of the strip is inclined toward the axis of the closure.
Claim 7
Dependent Claim
22 words
The device of claim 1 wherein the bead defines a substantially vertical face between an upper face and a lower, inner face.
Claim 8
Dependent Claim
18 words
The device of claim 1, wherein a lower, inner face of the bead defines a line of inclination.
Claim 9
Dependent Claim
64 words
The device of claim 1 wherein dimensions of the tooth and the notch are selected so that a rear, lateral face of the tooth, with reference to a direction of screwing, penetrates at least partially into said notch and is in engagement with a rear, lateral face of said notch before achieving a limiting value of a tensile strength of the zone of connection.
Claim 10
Dependent Claim
53 words
The device of claim 1 wherein the number and distribution of the teeth and notches and their respective vertical clearances are determined as a function of the mechanical resistance of the zone of connection and respective horizontal surfaces for mutual bearing contact, in order to achieve transmission of the vertical relationship for clipping.
