A container which includes body, neck and cover portions of one-piece plastic construction and a line of weakness defined between the neck and cover portions to permit selective separation of the cover from the neck, further includes an inner closure carried by and removable with the cover portion to prevent spillage of the container contents upon opening of the container. The inner closure is disposed to seal the neck below the line of weakness to isolate the contents of the container from the area of the line of weakness. When the container is heat sterilized, means is provided associated with the chamber defined by the cover and closure to prevent collapse of the cover during the post heat-sterilization cooling cycle. The associated means includes structure to provide moist air in the defined chamber during heating of the container without endangering the sterility of the container contents or nullifying the advantage of the inner closure.
In a one-piece, hermetically sealed plastic container having a body portion, a neck portion, a cover portion closing the neck portion and a line of weakness defined between the neck portion and the cover portion to permit separation of said cover portion from said neck portion, the improvement comprising, in combination:
In a container comprising a body portion, a threaded neck portion and a cover portion closing said neck portion, all of one-piece plastic construction, a frangible line of weakness defined between said neck portion and said cover portion, and a removal ring threadedly received on said neck portion and operable upon rotation to exert an axial force against said cover member to fracture said line of weakness for removal of said cover portion, the improvement comprising, in combination:
A hermetically sealed, heat-sterilizable plastic container comprising:
A hermetically sealed, heat-sterilizable container comprising:
A hermetically sealed, heat-sterilizable container comprising:
A method for sterilizing a plastic container which includes body and neck portions defining a volume, a cover portion closing the neck portion and a closure engaging the neck portion, carried by the cover portion and disposed to segregate the container contents from a line of weakness defined between the neck and cover portions, the steps comprising:
