A small fire extinguisher equipped with a rotary knob includes: a body part storing loaded stream; a nozzle part that is attached to the top of the body part and includes a valve at the inner center where compressed the loaded stream is sprayed, and a key insertion part where an L-shaped lock key is inserted or removed; a button part that is inserted and attached to the top of the nozzle part to open and close the valve with the button vertically entering in and coming out of the nozzle part; a plate rotary knob that is attached to one side of the nozzle part, covers up one end of the nozzle part, contacts the top of the button part, and is attached with a lock key; and a lock key which is attached to the plate rotary knob and stops or rotates the plate rotary knob.

A handheld dispensing device has a first dispensing element configured to dispense a structural material and a second dispensing element configured to dispense a biological material. The second dispensing element is single-use and sterilizable. The first dispensing element is connectable to the second dispensing element. A dispensing system also is provided and has a sterilizable chamber; at least one robotic arm assembly and a dispensing device within the sterilizable chamber. The at least one robotic assembly is configured to move the dispensing device that has a first dispensing element and a second dispensing element. The first dispensing element is releasably connectable to the second dispensing element. An external control is device connected to the robotic arm assembly and controls the at least one robotic arm assembly. The first dispensing element dispenses a structural material and the second dispensing element dispenses a biological material.

The invention pertains generally to an improved fluid dispensing device, particularly a dispensing device which employs at least one hemispherical domed cannister source of reactants and which uses a color-changing dispensing plastic tip to inform the end-user if the reactants are at a proper use temperature.

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 combined lid/valve device including a lid, for a pressurised product dispensing container, and a valve mechanism, in which the lid is provided with a so-called upper face and a so-called lower face, in which the lower face of the lid includes a base provided with a skirt for receiving the neck of a pocket containing the product to be dispensed, the base forming a housing for the valve mechanism consisting of a dispensing tube and a sealing gasket, the sealing gasket mounted on the dispensing tube snap-fitting into a through-hole between the upper face and lower face of the lid and allowing an outlet end of the dispensing tube to project beyond the upper face of the lid.

A spray canister holding apparatus that includes a collar for connecting to a spray canister, made of a non-continuous circular gripping structure having at least one opening along a circumference of the circular gripping structure, a lever arm rotation member, a vertical backing member attached to a posterior continuous portion of the circular gripping structure and extending upwards from the circular gripping structure, and a wire support opening connected to the circular gripping structure. The apparatus also includes a lever arm on the collar, a connecting wire attached to the lever arm, a handgrip attached to the connecting wire, and a discharging nodule appended to the lever arm, where the discharging nodule acts on a spray canister dispenser button.

System and methods concerning easy preparation of frozen food treats and in particular, frozen food treats that are molded into desirable and fun shapes. The system and methods are directed to dispensing a treat formulation into molds. Generally, such methods and systems utilize a pressurized canister, a treat formulation and an actuator. The pressurized canister has a pressure-actuated nozzle. The treat formulation can be blended and compressed into the pressurized canister with a gaseous propellant. The treat formulation can contain a dairy cream or a non-dairy cream, and two or more of sugar, sweetened condensed milk, vanilla and egg. The actuator is configured to apply pressure to the nozzle so as to trigger the release of the treat formulation through the nozzle.

A small fire extinguisher equipped with a rotary knob includes: a body part storing loaded stream; a nozzle part that is attached to the top of the body part and includes a valve at the inner center where compressed the loaded stream is sprayed, and a key insertion part where an L-shaped lock key is inserted or removed; a button part that is inserted and attached to the top of the nozzle part to open and close the valve with the button vertically entering in and coming out of the nozzle part; a plate rotary knob that is attached to one side of the nozzle part, covers up one end of the nozzle part, contacts the top of the button part, and is attached with a lock key; and a lock key which is attached to the plate rotary knob and stops or rotates the plate rotary knob.

A dispensing system includes a container and an overcap. The container includes a central, longitudinal axis and a first outermost point. The first outermost point of the container is a first distance from the central, longitudinal axis along a first line perpendicular to the central, longitudinal axis. The overcap is coupled to the container and includes a pivotable trigger that is configured to pivot between an unactuated position and an actuated position. A second outermost point of the trigger is a second distance from the central, longitudinal axis along a second line perpendicular to the central, longitudinal axis when the trigger is in the unactuated position, the second distance less than the first distance. Further, the second outermost point of the trigger is to move toward the central, longitudinal axis when the trigger moves toward the actuated position.
