A container has an elastically deformable body and a neck including a chamber connected with the container interior and the discharge opening of the neck by means of passages which are sized, shaped and positioned to prevent accidental spillage of the product, even if the container is horizontal. At least one of the passages may have a crosssection which is lenticular in shape, squashed at first but having geometry variable between an undeformed configuration when closed, and a deformed configuration when open that allows outflow of product when the container is purposely squeezed by the user. On releasing the container, the shape of the cross-section returns to its initial almost closed, configuration.
