PROBLEM TO BE SOLVED: To provide a screw cap inside part plug (cork) integrated plug making the attachment and detachment of the plug of a sealed container simple, stable, and labor-conserving and simultaneously having the functions of sealability, deaeration, gas permeability, antibacterial characteristic, and sterilization characteristic by solving the problem that a capping instrument or another tool such as a cork plug remover is needed with labors and forces for opening and closing a container of wine or beer, and that user's demand is insufficient in viewpoint of sealability or deaeration.SOLUTION: A screw cap 1 is integrated with an inside part plug 2 (cork). The screw cap is made of a high gripping material and shape (grip 4) to be capable of being attached and detached in simple, stable, and labor-conserving manners by deformation using auxiliary components such as deforming rotary auxiliary lever for providing the container inside or the inside part plug with screw grooves. Alternatively, the plug has a function corresponding to contents or user's demands by using a multifunctional material having functions such as sealability, deaeration, gas permeability, antibacterial characteristic, and sterilization characteristic for a cladding material.SELECTED DRAWING: Figure 2 |
