The composite cap acecading to the: mvention is described above in die condition it is is before it is placed over tlte glass ring of the bofeie, the pskst being in an axially uncompressed state. Ater fastening over said glass ring and alter first opening, one portion of this Composite cap remains rigidly connected to the glass ring and another portion takes the form ofa cap that can be screwed on and off as desired, closing or opening the pouring orifice of said bottle.

[0011] The glass ring is either provided with an external screw'thfpad if it is intended to accommodate a serew~on composite cap, or provided wife fastening means allowing It to be rigidly connected to an insert having as external screw thread if it ts Intended to accommodate a pushrtm composite cap. file upper portion of the glass ring is provided with a transverse wall, typically perpsndicahn’ to the axis of the bottle neck, and with an miter eyinrirical wall, stthrtmnMiy cylindrical about said axis, said walls icing separated by an outer toroidal wall, the cross-section of which is typically delimited by a quarter-circle with a radius R. To have particularly good sealing in the region of contact between the seal and the top of the ring, glass rings can be used such as those shown in P% S of document GME 30*0® to* CEIIE ilmernntional Technical Center lor BCtding and Related Packaging); these hays a lip, irieorporstipg the lop wall and most of she toroidal wall, fee surface of which has been specially treated ("sealing surface") and a “hat" Incorporating the rest of the toroidal wall and a relatively short outer cylindrical wall, extending as fa? as fe® mould seal. For a ring of this sod,: the diameter De is that of saM relpiiypiy short: outer cylindrical surface. Í0012] The composite cap according to fee invention comprises a shell, typically made of metal and having a substantially cylmdriesi external skhP 1 coidprisds at least one htsst, said Insert being: contained within said shell and rigidly connected thereto. The insert comprises a: head comprising a transverse wall: provided with a lower face feeing into the bottle.

Preferably, tire diameter D) is also less than then inner diameter such that: said gasket lies within its housing without deformation. The difference f|-í)e is preferably greater fean or equal to E, such that the seal can be correctly pressed on, and less than 3E, safe that fee annular bending exacted m. tbs end border can take place without folds or uon^contaci regions feeing: formed.

Pill When said composite cap is festened over fee glass ring, the cap is moved towards: the bottom of fee bottle then fenmefellised axially relative to fee glass ring. In fee ease of a screw-on composite: cap, such as that described m W I 254 Ö59, the cap> is se&amp;spsi :«ό -fes$|; fee -rig|kiefe®g. torque reaches a predetermined value. Indeed, said dghteofng torque feas to increase during screwing in, owing to Medonal torque, whiefe rises as the contact surface wife the thread increases and as fee feme exerted on fee: thread metsases, owing to the roaef on of fee seal, which is mereasingiy compressefi Once fee predetermted tightenfeg forepe value is reached, there is sufficient Motion on fee thread to keep the cap immobile and rigidly ceauected to the neck of fee bottle. Imfeobdisatioo of fee cap is compl eted by fee feel being Crimped under a projecting portion of fee glass ring, known as a “crimping countering” or ‘^oanfor-ring?’. In fee case of a push-on conrposiie cap, as described In pában application EPS 522 S§1 Ai, the composite cap Sited around tie glass ring is pushed m. hy: esial Musiadón «8 the cap is trapped m s hcifeug because of the mopsíat sort between the push*on m&amp;sm of the sscmvf insert mé the glass mg. The sheM>; crisped under iht. losw sail of the second insert before the cap is fitted to the· seek o f the bottle, Is ^dhestlji trapped oaths .glassware, |ÖÖ16| Whatever type of composite cap Is ssleet&amp;i ihe geometry, shaeíore^ »ale«sí: «^^rpatenaila pf sfeci various: components: of said cap are such that, right at the: end of the jasstóijg;. ms^me^. 'Whgg: fee dinsiposite cap is felfeded over the glass ring, said gasket Is axially compressed betweeti said lower face of the head of the Insert and said top Wad. For example, for a push-on cap;: fits: axial distance between the apex of the- push-on lugs and the lower face: of the head' of she Insert Is less than the sum of the thickness of the: seal and the axial distance between the abutment face of the pash-mo bead of the glass ring and the top wall of the lip. This constitutes a first compression means, which acts on the portion of the seal that has hess called the “axial compression zone”. Ifie value of compression exerted oa said oxM compression stone at the end of the pushing roovement depends on the nature of the matériái selected for said resilient layer. Typically, with a; resilient layer made of EPE (expanded polyethylene), ÉC compresslps of said axial csuipression zone coirespebds to a reduction of its thickness to about half of the value, prefeably of between one-quarter end three-#srters of said thickness,: {ÖÖ17J However, the composite cap according to the touani&amp;m also comprises at least one peripheral fenming means associated with an oblique compression means, closer to the axis, which act, in a time-staggered rnsnher, on the end border of the gasket beibre said first compression means. Is. before the lower face of the head; of the idsetl exerts axial compression cm the axial eeffiprmton zone of said gasket the apfdibadt based its solution oh Été Observation that passioning a perfect seal requires *| close md even contact with the periphery pf the glassware, i.e. with the outer toroidal wail aod the outer eyilu^soal wall of the upper part of the glass dug. However, this even, contact Is not produced sufficiently well fepst the first compression; mesas- M: already seggesed In: BP 1 63S 653, additional compression with, a radial compqueut, exerted on the peripheral portion of tig seal, is required. The additional teaefelug ssawided fey the pessaf invention lies In the Tact that there Is m risk that the radial compression exerted fey s ficxlbie armular lug is: sot saffieient, particularly in the ease of push^on taps, and that it is preferable to provide the cap :«#t means thai alow the seal to be deformed to a none controlled manner when its peHptey undergoes annular bending, Until said periphery comes into contact: with the outer eylludfleal: wall of the upper portion of the glass ring, wbile pfeventsog folds and aon-contaet regions ix)hi feeisg fedned in the region of said enntast fööífj When the composite cap is fastened over the glass ring, whether said fetching is carded out: fey screwing or pushing on, the composite cap has to fellow a poshíagWín movement thai brings it closer to the bottle. During this poshing movement: »} said pdpheraf fermog means is the first hr come Into contact with said gasket at the periphery of the end border, drives it as it moves so that the contact surface extends progressively Írom the outside inwards, and exerts annular bending m said end feorder, Which results In complex deformation combining squeezing, olongafion irúfialfy in a radial di^etfes, eonfiaetloa in a drcumferenfial direction and reduction in dtiekuess. The geometry of said forming means is such that, while she cap is feeing pushed on, the end border of the gasket mis op, at the end of fere pushing-onon movement, being pressed ever the outer s^íSsááe&amp;í surisce of É»: top pMloa of the glass ring; b) said oblique compression mm® is the: second to smm·. into contact with said gasket, at the mi border but close is the axial compression wm* while the end border is already deflected sumdarly, and therefore squeezed. This oblique compression means traps this: portion of the end border that is dose to the axial compression zone and exerts: “pinching’5 os it which* in this region of tire thick seal, reduces the risk of unstable dethromtion and the ifernmfeon pf folds and/or non-contact regions.

The first annular bead , partly attached to the inner wall of the internal skirt of the insert is the peripheral forming msem. It captures, drives and squeezes the end border of the gasket. As the end of the p«sbiog-on movement, it exerts a stress having a small axial eemponent and a large radial component, pressing the gasket against the outer surface of the top portion of the glass ring. The second bead, less peripheral than the first one, is fete oblique compression means. It comes into contact with the gasket after fete ftrsf bead and exerts on the portion of the end border that is situated in the vicinity’ of the axial compression zone an oblique stress Shat presses said portions over said outer toroidal wail. The lower face of the head of the insert plays a final role of pressing the seal over the ip.
