An aerosol spray can has a can body, a valve assembly, a dip-tube assembly and a rigid tube. The valve assembly is mounted on the can body. The dip-tube assembly is connected to the valve assembly and has a head end channel-linked to the valve assembly. The dip-tube assembly has a flexible tube and a weight piece. The two ends of the flexible tube are connected to the valve assembly and the weight piece respectively. The rigid tube is sleeved around the flexible tube to constrain excessive bending of the flexible tube. The flexible tube protrudes from the rigid tube. The weight of the weight piece drives the tail end freely toward the ground. Therefore, the tail end stays submerged under a liquid product when less than a half of the liquid product is left inside the can body even when the can body is tilted or horizontal.

A novel foam dispenser is described, which comprises a dispensing container, a valve with a downstream foaming chamber and a pressure control device for maintaining a constant pressure in the container, such that uniform and compact foam will be created.

An aerosol dispensing system has a container assembly, an actuator assembly, and a trigger member. The container assembly has a valve assembly. The actuator assembly has an actuator housing defining a rail portion, a trigger member pivotably attached to the actuator housing, and an outlet assembly defining an outlet opening. The outlet assembly is slidably supported relative to the actuator housing by the rail portion. The trigger member engages the outlet assembly such that application of deliberate manual force on the trigger member causes pivoting movement of the trigger member relative to the actuator housing and such that pivoting movement of the trigger member relative to the actuator housing causes linear movement of the outlet assembly relative to the actuator housing. The outlet assembly engages the valve assembly such that linear movement of the outlet assembly alters the valve assembly from a closed configuration to a fully open configuration.

The invention includes a system to reduce deposits from a surface of an intake valve, preferably in a GDI engine. The system includes a delivery device having a reservoir for holding a cleaning agent. The reservoir has a body that defines an interior space, and an outlet port in fluid communication with the interior space of the reservoir body. The delivery device has a delivery conduit that extends from the outlet port and terminates at a distal end. The proximal end of the delivery conduit is in fluid communication with the outlet port. An actuator having an open position and a closed position is included in the delivery device. Upon activation of the actuator from a closed position to an open position, a portion of the cleaning agent flows from the interior space through the outlet port and is delivered under pressure to distal end of the delivery conduit. The cleaning agent includes a detergent, a carrier, and an oil. In a preferred embodiment, the system is an aerosolized. Also contemplated with the scope of the invention are related methods of removing deposits from the surface of an intake valve and/or of enhancing or improving engine performance.

A device for dispensing pressurized air and/or tire sealant from a pressurized can. The device comprising a cap body, a depressor button with a lock clip, and a hose positioned within the cap body attached to the pressurized can. The lock clip locks the depressor button in the compressed position for ease during use, while a shield element keeps the depressor button in the non-compressed position for safety during non-use. The hose provides an extension to attach to a tire stem valve, while being stored and attached to the cap body of the device.

A fluid dispenser member, such as a pump, comprising a body (11) for mounting in the opening of a fluid reservoir so as to take fluid therefrom, the body (11) comprising a fluid chamber (15) that defines a fluid inlet in the form of a socket (12), the dispenser member including a dip tube (2) for extending into the fluid reservoir so as to take fluid therefrom, the dispenser member further comprising a reducer sleeve (3) that internally receives an end (21) of the dip tube (2), and that is engaged axially in the socket (12) of the body (11), such that fluid communication is established between the dip tube (2) and the chamber (15) of the body (11);

the dispenser member being characterized in that the dip tube (2) presents an outside diameter that is less than 1 mm, and in that the dip tube (2) is made of a material that is transparent or translucent.
