Looks like the ones I have used for about 3 years. The tips on mine do NOT screw onto the bottles and with heavy squeezing will pop off. However, I use some tape to secure tip to bottle. When done, remove the tape, apply the original plastic top and then soak the tip in water to remove the glue and then dry. Or, if not wanting to wash each time, I use the smallest tip, secure it with tape and when finished, I stick a pin in the tip and stand upright. This way the tip will not clog with dried glue.
