Closure system for a container including a cap and a ring adapted to engage by screwing in order to seal the opening, the cap including an upper wall from which in a downwards direction there extends an annular skirt that has a lower annular end and a radially inner surface fitted with a thread. The ring has an annular top rim, an annular collar and a thread complementary to the thread of the cap provided between the collar and the rim of the ring. The skirt of the cap includes a projecting annular member forming a barrier and adapted to be supported against the whole periphery of the collar of the ring in a substantially radial direction.

1. A closure system for a container, comprising: a cap; anda ring defining a container opening,wherein said cap and ring are configured for screw engagement to seal the opening,said cap comprising an essentially circular top wall from which there extends a downward annular skirt having an annular bottom edge and a radially inward face provided with a screw thread,said ring having an annular rim forming said opening, an annular collar projecting out radially as far as a radially outermost face and a screw thread, complementary to the screw thread of the cap located between the collar and the rim of the ring,wherein said skirt of the cap comprises at least one annular barrier member which projects from said radially inward face and is adapted for bearing in a substantially radial direction against the entire periphery of said radially outermost face of the collar, andwherein said skirt of the cap and said at least one barrier member are formed integrally of one piece of a same material. 2. The closure system as claimed in claim 1, wherein said at least one barrier member is formed by an annular bead projecting from said inward face of the skirt of the cap in a radially inward direction. 3. The closure system as claimed in claim 2, wherein said bead has an inside diameter that is less than the outside diameter of the collar, and wherein said skirt of the cap is capable of tolerating an outward radial deformation when said bead engages on a longitudinally upper face of said collar. 4. The closure system as claimed in claim 1, wherein said at least one barrier member is formed by an annular lip extending from said inward face of the skirt of the cap and constructed so as to be deformed on contact with said collar of the ring. 5. The closure system as claimed in claim 4, wherein said annular lip extends essentially downwards. 6. The closure system as claimed in claim 5, wherein said annular lip forms a continuation of the inward face of the skirt. 7. The closure system as claimed in claim 4, wherein a peripheral recess is formed in said skirt of the cap adjacent to said annular lip and externally relative to said annular lip. 8. The closure system as claimed in claim 1, wherein said collar has a longitudinally upper face connecting said ring to the radially outermost face, said upper and outermost faces being connected by an outline essentially in the shape of an arc of a circle. 9. The closure system as claimed in claim 1, wherein said screw thread of the ring is within a predetermined maximum outside diameter, and wherein said at least one barrier member does not extend inwards further than a minimum diameter greater than said predetermined maximum diameter. 10. The closure system as claimed in claim 1, wherein said at least one barrier member is close to the annular bottom edge of the cap. 11. The closure system as claimed in claim 1, wherein said cap also comprises sealing means extending from its top wall and engaging with said ring close to said annular rim of said ring. 12. The closure system as claimed in claim 1, wherein said skirt of the cap comprises a plurality of barrier members each arranged closer to the annular bottom edge of the cap than the screw thread of the cap. 13. The closure system as claimed in claim 1, wherein said skirt of the cap is part of a single piece made of a same plastic. 14. The closure system as claimed in claim 13, wherein said skirt of the cap has an outer face extending from said top wall as far as said annular bottom edge, said outer face of the skirt defining a constant outer diameter of the skirt. 15. A closure system for a container, comprising: a cap; anda ring defining a container opening,wherein said cap and said ring are suitable for screw engagement to seal the opening,said cap comprising an essentially circular top wall from which there extends a downward annular skirt having an annular bottom edge and a radially inward face provided with a screw thread,said ring having an annular rim forming said opening, an annular collar projecting out radially as far as a radially outermost face and a screw thread, complementary to the screw thread of the cap located between the collar and the rim of the ring,wherein said skirt of the cap comprises an annular barrier member which projects from said radially inward face and is adapted for bearing in a substantially radial direction against the entire periphery of said radially outermost face of the collar,and wherein a peripheral recess is formed in said skirt of the cap, said peripheral recess being adjacent to said barrier member, the barrier member being arranged closer to the annular bottom edge of the cap than the peripheral recess,wherein said cap is formed integrally of one piece of material. 16. The closure system as claimed in claim 15, wherein the material of said cap is a plastic material.
