Methods and systems for coupling gas and water supply tubes to a container. An illustrative container and tube set may comprise a container configured to contain a fluid, the container having a bottom portion and a top portion, a water supply tube including a first end, a second end, and a first lumen, a gas supply tube including a first end, a second end, and a second lumen, and a weight coupled to the first end of the water supply tube and a first end of the gas supply tube. The first lumen may be in selective fluid communication with the bottom portion of the container and the second end of the water supply tube positioned external to the container. The second lumen may be in operative fluid communication with the container and the second end of the gas supply tube is positioned external to the container.

A cartridge for a nebulizer having a connection element, includes: a container containing a fluid to be nebulized; a closure having a connection port for fluidically and/or sealingly connecting the container to at least one of the nebulizer and a delivery mechanism thereof; and a sealing element disposed between the closure and the container for forming a sealing, where the sealing element is adapted to sealingly receive the connecting element of the nebulizer after passing through the connection port.

A product applicator is secured to the blower tube of a portable air blower and incorporates an adapter nozzle assembly and product storage container. The adapter nozzle assembly is located at a distal end of the blower tube, and includes a substantially hollow tubular housing and a discharge nozzle located inside the housing. The housing has a discharge end and a connecting end adapted for being arranged inline with the discharge airstream supplied by the blower. The product storage container is located proximate the housing, and is designed for storing a product to be discharged through the nozzle. A flow regulator is adapted for selectively adjusting a supply of product from the container to the discharge nozzle.

A fluid flow sinker including a body having a generally cylindrical sidewall, a first end, a second end, and an aperture extending between the first and second ends; and a fluid passageway disposed on the first end and extending from the generally cylindrical sidewall to the aperture, wherein the fluid flow sinker is adapted to receive a tube in communication with the aperture.

A cartridge and a nebulizer for nebulizing a fluid as well as a method for fluidically connecting the cartridge to the nebulizer are proposed. The cartridge comprises a closure with a valve, wherein the valve displaces fluid into the nebulizer when opened. Further, the cartridge forms two axially spaced sealings with the nebulizer when connected.

A marking system for a robot is provided, comprising, a paint container configured to store a paint for marking, a head for spraying or printing the paint, a hose for delivering the paint to the head, said hose comprising a first end being connected the head and a second end being inserted into the paint container, and a negative pressure device for extracting the paint from the paint container into the hose, wherein a guiding device is received in the paint container, said guiding device being configured to keep the second end of the hose being in contact with the paint regardless of the paint container's orientation.
