A membrane-penetrating closure device for a container on which a sealing membrane (e.g., a metal foil) is installed. The device comprises a membrane-penetrating structure disposed within a tubular channel. One end of the tubular channel is secured to the container, while the other end is provided with a re-sealable cap. The membrane-penetrating structure is initially disposed proximate to the sealing membrane, and the closure device is arranged such that the membrane-penetrating structure will pierce the sealing membrane, thus opening the container, either as a result of opening the re-sealable cap or upon application of manual pressure to the piercing structure. The tubular channel may be provided with tamper-resistant or tamper-evident portions at one or both ends.
