Abstract
A plastic tamper-proof sealing plug assembly for use in securely sealing the vale outlet of a pressurized bottle or any other type of container. The tamper-proof assembly has a tubular gasket provided with a central opening, sized to fit into and seal a valve outlet, and a sealing plug element with a plug projecting from it, which is sized to snugly fit into the tubular gasket in order to close the valve outlet. The tamper-proof assembly also has a security seal in the form of a strap has one end attached to one side of the sealing plug element and also has another free end. The strap projects outwards from the side of the sealing plug element and is long enough to surround the valve. The tamper-proof assembly further has a fastener for irreversibly fastening the free end of the strap to the sealing plug element so that the strap must be broken in order to remove the plug and the gasket if necessary, from the valve outlet. This gives a visible indication to anyone using the bottle that the plug and the gasket have previously been removed or tampered with. This assembly may also consist of a moulded, one-piece tamper-proof assembly where the gasket and the sealing plug element are combined together in a combined gasket and sealing plug element unit. However, when the gasket and the sealing plug element are moulded into a one-piece tamper-proof assembly, they are separated from one another before they are installed on the valve outlet.
