Open the CIPO recordAbstract From the Canadian patent
Child-resistant safety closures are provided for closing the outlet of a hand-operated fluid product sprayer dispenser to prevent leaks during periods of non-use and to resist accidental use by children or unwar adults. The closures cannot be moved from an "outlet closed" position to an "outlet open" position without the performance of two separate and definite actions by the user to first disable the lock and then to rotate or linearly move the cap into the "outlet open" position to permit spraying or dispensing.

Why it's free to use
- Granted August 25, 1981. A Canadian patent filed before October 1, 1989 lasted 17 years from grant, so its term ended August 25, 1998.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
