Abstract: A container with a threaded neck and a non-spin threaded top and ring seal device. The top and the ring seal are frangibly attached. The neck has an upper zone with a helical thread and lower smooth zone with a diameter larger than the upper zone. Between the upper and lower zones is a serrated edge with teeth having oblique upper surfaces for easy insertion/assembly of the top and ring seal. Above the serrated edge there is an annular projection which defines an oblique annular tooth which holds the ring seal in place after the seal is broken, preventing it from coming out of place when the product within the container is being used. There is also another annular projection below the serrated edge near the bottom of the lower zone which centers the ring seal but does not prevent it from dropping when the seal is broken.
