An easy-open and tamper-evident beverage container and opening system for the beverage container are provided which include a container barrier wall. The barrier wall has a series of slits therein which define a pierceable straw hole. The series of slits divides the barrier wall into a hole portion and a remainder portion, with the hole portion connected to the remainder portion by attachment points provided between adjacent slits of the series. A membrane seal is located inside of the container and sealingly covers the straw hole. This membrane seal is liquid impervious and includes (a) an outer portion which is sealed to an inside surface of the front barrier wall about the straw hole, and (b) an inner portion integral with the outer portion which is not sealed to the inside surface of the barrier wall and which covers the straw hole. With this construction, when piercing the container with the straw, the straw breaks at least some of the attachment points as the straw pushes on the hole portion and as the straw then easily pierces the membrane seal. The breakage of the attachment points thus provides readily observable and unrepairable evidence of opening of the straw hole. Preferably, the series of slits form a circular straw hole and the membrane seal is circular and centered about the straw hole.
