选择性密封的容器内衬

Original abstractA reversible sack that is suitable for use as a container liner is disclosed. The sack is selectively sealable and in one example can be opened and/or closed to varying degrees. More particularly, the sack has an open end and one or more mechanisms associated therewith that facilitate opening and/or closing the open end of the sack. In one example, the sack also includes a mechanism that facilitates maintaining the open end of the sack in any of the various degrees of opened and/or closed conditions. The sack functions the same regardless of whether it is in a reversed or un-reversed configuration. The reversibility of the sack provides for added versatility and allows a user to employ the sack in an un-reversed and reversed configuration as may be desired and appropriate given particular settings, surroundings, times, seasons, etc.
