Abstract
A spout and sealing cap assembly for a container which contains a product such as a liquid or pasty product. The container includes a nick closed off by a lid that must be pierced for dispensing the product. The assembly includes a spout with a body that is fixed to the neck. The spout also includes a hollow piercing and dispensing element provided with sharp edges designed to pierce the lid. The element is suspended inside the body by a deformable annular bulged membrane which enables the piercing element to assume an upper position and a lower position wherein the sharp edges extend below the ruptured lid. The spout body is covered by a sealing cap which assumes either an open or a closed position. The cap includes a sealing member extending of a top section of the cap. When the cap is closed, the sealing member is designed for insertion in sealing fashion within the hollow element or in a fitting and sealing relationship about the hollow element both when the element is in the upper and the lower position.
