Abstract: A child resistant closure apparatus between a container and a cap comprises a separate safety lock ring. The lock ring is mounted over the container neck and the cap is mounted on the container neck and engages with a pair of lock clasps on opposite sides of the lock ring. Finger pads on opposite sides of the lock ring are squeezed and compressed by one hand of the user while the cap is rotated on the container neck by the other hand of the user to separate the cap from the container. The lock ring is designed to be employed with container and cap closure assemblies of at least two different sizes, reducing their manufacturing costs. Additionally, the lock ring may be removed from the container if it is desired that the container and cap not have a child resistant closure apparatus.

The dispenser body has first and second pump chambers, a first intake port adapted for fluid communication with a first liquid source, a second intake port adapted for fluid communication with a second with a first liquid source, a second intake port adapted for fluid communication with a second liquid source, first and second intake liquid flow paths for passage of fluid from the intake ports to the pump chambers, and first and second discharge liquid passageways. A third discharge liquid passageway is defined at least in part by the dispenser body. The third discharge liquid passageway includes a mixing chamber and a spinner chamber downstream of the mixing chamber. The first and second discharge liquid passageways are configured for passage of liquid from the first and second pump chambers to the mixing chamber.

Abstract: A child-resistant liquid dispenser such as a trigger sprayer. The dispenser comprises a dispenser body, a nozzle, and a locking mechanism. The dispenser body has a nozzle receiving end and a discharge passage configured for discharging liquid through the nozzle receiving end. The-nozzle has a nozzle opening therein and is connected to the nozzle receiving end of the dispenser body. The nozzle is rotatable relative to the dispenser body about a nozzle axis X between open and closed positions. The nozzle and dispenser body are configured such that the nozzle opening is in fluid communication with the discharge passage of the dispenser body when the nozzle is in its open position to permit fluid to flow from the discharge passage and through the nozzle opening. They are further configured such that fluid communication between the nozzle opening and discharge passage is blocked when the nozzle is in its closed position to prevent fluid flow from the discharge passage and through the nozzle opening. The locking mechanism comprises a locking member adjacent the nozzle and dispenser body. The locking member is moveable along the nozzle axis X between locking and unlocking positions. The locking mechanism, dispenser body, and nozzle are configured to prevent rotational movement of the nozzle from its closed position to its open position when the locking member is in its locking position and to allow rotational movement of the nozzle between its closed and open positions when the locking member is in its unlocking position.

Abstract: A manually operated reciprocating fluid pump for securement to a container's mouth. The fluid pump comprises a dispenser body, a closure cap, a seal assembly, and a priming check valve. The dispenser body has a pump mechanism, a discharge port, and a discharge liquid flow path providing fluid communication between the pump mechanism and discharge port. The closure cap is connected to the dispenser body and is configured for closing the mouth of the container. The seal assembly has a first portion and a second portion. The first portion is shaped and configured for preventing leakage between the closure cap and the mouth of the container when the closure cap closes the mouth of the container. The second portion has an intake port adapted for fluid communication with liquid contained in the container. The second portion of the seal assembly and the dispenser body define an intake liquid flow path providing fluid communication between the intake port and the pump mechanism. A check valve in the intake liquid flow path is configured for permitting fluid flow from the intake port to the pump mechanism and for checking fluid flow from the pump mechanism to the intake port. The second portion of the seal assembly comprises at least part of the check valve.
