Abstract: A resealable, reuseable, insertable bottle assembly for open beverage containers containing wine, carbonated drink and the like, for preservation against environmental degradation, having a deployable and retractable flexible material for engagement against the drink, a plurality of hinged leaves for engagement with the flexible material at a multiplicity of locations for deployment and retraction further having a spring, a coupling for coupling the hinged leaves, insertion/extraction device for inserting and extracting the assembly, a device for causing the leaved means to move from deployment to retraction. The assembly further includes a gasket as well as telescoping ability for extending and retracting the assembly to enable various levels of drink. In one embodiment, deployment to retraction occurs by way of a cranking for deploying a cable to enable winding and unwinding for deployment and retraction, respectively.
