A snap-on bottle cap seal device is made of an elastic material, such as a plastic, and is formed of a reusable sealing cap and a ring-shaped safety strip detachably secured to and extending circumferentially about the lower end of the cap when it is initially secured on a bottle. The centrally disposed portion of the top surface of the sealing cap is concave and a tubular projection extends downwardly from the under side of the centrally disposed portion for engagement within the mouth of the bottle being sealed. An inwardly directed protuberance is formed on the inner surface of the skirt of the sealing cap and an outwardly directed protuberance is formed on the lower end of the tubular projection so that both protuberances provide a sealing effect against opposite surfaces of the bottle. A lifting lug is formed on the lower edge of the sealing cap and a tear-off tab, attached to the safety strap, is secured by small web sections to the lug. Passages are formed between the safety strip and the bottle and the passages extend between the lower end of the strip and grooves formed in the lower outer surface of the sealing cap. The passages are arranged to effect a rinsing of the sealing device after the bottle has been filled and sealed.
