We also have several patents pending for child resistant caps for various types of pump sprayers, as shown below.


CR Overcaps for Pump Sprayers, Bottom Lift

To dispense a product using this child-resistant overcap, the consumer removes the cap, inverts it, and slides it on to the bottom of the container where it snaps into place. The inner pump or aerosol sprayer can then be pushed upward, actuating the sprayer and dispensing the product. After use, the cap is removed from the bottom of the outer container, the spray unit drops down inside, and the cap is placed back on top.

This cap design can be utilized with pump or aerosol sprayers and is ideal for smaller, easily carried containers. View the patent for the Child Resistant Container with Inverting Cap and Bottom Lift.

We have another bottom-lift design suitable for vertical nozzles, our Child Resistant Container with Inverting Cap Bottom for Vertical Nozzles. In this version the consumer removes the cap, inverts it, and slides it on the bottom of the container. This pushes the spray unit up and allows the consumer to operate the sprayer in a normal way using their fingertip to actuate the unit. When finished, the consumer removes the cap from the bottom of the unit and the pump slides back down into the CR container. The cap is is then returned to the top of the unit.


CR Overcap for Pump Sprayers, Top Lock

To dispense a product using this child-resistant overcap, the consumer removes the cap, inverts it, and slides it back on top of the container. Downward pressure applied to the inverted cap now pushes on the inner sprayer and dispenses the product. After use, the cap is removed from the top of the outer container, flipped over and placed back on top of the container.

CR Overcap for Pump Sprayers, Twist Lock

To dispense a product using this child-resistant overcap, the consumer aligns the indicia on the cap, pushes down, and then rotates the cap to a stop. The cap can then be removed and the product is ready to be dispensed. After use, the cap snaps back on in any position.
