Abstract: A roll-on applicator which allows venting of gases between the inside and the outside of said applicator. This applicator comprises a ball within a dispensing opening and a flexible and resilient support means for said ball. Said flexible and resilient support means is such to urge said ball against said dispensing opening, achieving a leak tight engagement between said ball and said dispensing opening. This engagement is such that the pressure built up inside said container is not efficiently released to the outside of said container. Furthermore, said flexible and resilient support means can be resiliently deformed by an external force acting on said ball to disengage said leak-tight engagement between said ball and said dispensing opening, allowing said contained product to be spread by said ball. Said applicator further comprises a cap which presses onto said ball creating a free passage between said ball and said dispensing opening only when said cap is engaged or disengaged from said container.

Abstract: The present invention relates to a roll-on applicator with a filling opening and a dispensing opening which prevents leakage or spillage without the need of the cooperation of a cap. This container comprises ball (3) and a flexible and resilient support means (4) for said ball. Said flexible and resilient support means urges said ball against said dispensing opening, achieving a leak-tight engagement between said ball and said dispensing opening. Furthermore, said flexible and resilient support means can be resiliently deformed by an external force acting on said ball to disengage said leak-tight engagement between said ball and said dispensing opening, allowing said contained product to be spread by said ball.

Abstract: The present invention is a venting cap (1) with a hole (4) and a semi-permeable membrane (7). The membrane is fitted in a housing (6) of particular dimensions which is in turn fitted in a protrusion (5) corresponding to the hole in the cap. The present invention further encompasses a process for the manufacture of the cap.
