摘要：
A container for a carbonated beverage has an interrupted external screw thread (8) surrounding its mouth opening (6) engageable with an internal screw thread of a rotatable closure (10). The rotatable closure has a top member (12) which is inwardly domed or idented or otherwise shaped to impart the necessary stiffness thereto. To prevent missiling on opening, pressure venting means are provided. Such pressure venting means may comprise slots extending through the closure (10), and/or the rotatable closure (10) may be provided with stops (46) which impart a two stage opening movement thereto. A rotatable closure with a low opening torque is made in two parts and has a top member (102) and a freely rotatable peripheral rim (108) carried by the top member.
