A one-piece container closure with a collar, leaflets hingedly attached to the collar, and thin flexible foldable webs attached to and extending between the leaflets . The leaflets are flat with the webs folded beneath in closed closure position. The leaflets are pivoted upwardly with webs unfolded therebetween in open position. An integral cap is attached to the collar by a snap-action bow-tie hinge. A central pin on the cap seals with the leaflets when the cap is closed. The closure is integrally molded in open position with raised leaflets and unfolded webs, leaflets then being lowered and the webs folded to closed position while the closure is still warm.

La présente invention concerne une fermeture de récipient d'un seul tenant comportant un col, des feuillets fixés par des charnières au col et de minces voiles pliables souples fixés aux feuillets et s'étendant entre eux. Les feuillets sont plats, les voiles étant pliés au-dessous en position fermée. Les feuillets pivotent vers le haut, les voiles étant dépliés entre eux en position ouverte. Un capuchon intégré est fixé au col par une charnière papillon à déclic. Une broche centrale sur le capuchon scelle les feuillets lorsque le capuchon est fermé. La fermeture est entièrement moulée en position ouverte, les feuillets dressés et les voiles dépliés, les feuillets étant ensuite abaissés et les voiles pliés en position fermée alors que la fermeture est encore tiède.
