A squeeze container capable of preventing a clogging caused by a powdery content is provided. The squeeze container capable of discharging a powdery content to an outside of the squeeze container, the squeeze container having two tubes suspended down to the inside of a container body to serve as through holes of the powdery content, the tip of one tube of the two tubes is fixed to one hole formed on an upper surface of the cylindrical body, the tip of the other tube passes through the other hole formed on the upper surface of the cylindrical body and extends to an internal space of the cylindrical body, and a gap is formed between a bottom of the container body and the opening of the cylindrical body so that the powdery content can enter into the internal space of the cylindrical body.

An orientation independent delivery device. The delivery device includes a gas chamber, a delivery chamber, a gas cell, and a delivery aperture. The gas chamber includes a gas-side rigid portion and a gas-side flexible barrier. The gas-side flexible barrier is sealed to the gas-side rigid portion. The delivery chamber includes a delivery-side rigid portion and a delivery-side flexible barrier. The delivery-side flexible barrier is sealed to the delivery-side rigid portion and is oriented adjacent to the gas-side flexible barrier. The gas cell is coupled to the gas-side rigid portion of the gas chamber. The gas cell increases a gas pressure within the gas chamber to expand the gas-side flexible barrier. Expansion of the gas-side flexible barrier applies a compressive force to the delivery-side flexible barrier allowing a delivery material to escape from the delivery chamber.

A disperser system includes a disperser body that defines a substantially air-tight chamber therein. A sprayer assembly includes a passage, a fluid coupling, a nozzle, a valve, a valve trigger and a pouch. The passage is in fluid communication with the chamber. The valve is in fluid communication with both the passage and the fluid coupling and opens to the nozzle. The valve trigger is configured selectively to open the valve, thereby placing the passage and the fluid coupling in fluid communication with the nozzle. The pouch contains a fluid. When the chamber is charged with a gas and when the valve is opened, the gas flows through the passage and the fluid flows through the fluid coupling into the valve so that the gas entrains the fluid and delivers a suspension of the gas and the fluid to the nozzle, out of which the suspension is sprayed.

An orientation independent delivery device including a replaceable cartridge that may be installed on a foundation. A cartridge includes a gas chamber, a delivery chamber, a gas cell, and a delivery aperture. The gas chamber includes a gas-side rigid portion and a gas-side flexible barrier. The gas-side flexible barrier is sealed to the gas-side rigid portion. The delivery chamber includes a delivery-side rigid portion and a delivery-side flexible barrier. The delivery-side flexible barrier is sealed to the delivery-side rigid portion and is oriented adjacent to the gas-side flexible barrier. The gas cell is coupled to the gas-side rigid portion of the gas chamber. The gas cell increases a gas pressure within the gas chamber to expand the gas-side flexible barrier. Expansion of the gas-side flexible barrier applies a compressive force to the delivery-side flexible barrier allowing a delivery material to escape from the delivery chamber.

A squeeze bottle, useful for atomizing liquids such as perfumes, medications, insecticides, or the like, by manually squeezing the bottle while orienting the bottle to direct the resulting atomized spray for a desired application. The squeeze bottle utilizes ambient air and contains an inner, compliant pouch for storing a liquid. The pouch is configured so that it deforms by the hydrostatic air pressure generated within the bottle during a squeezing action. This deformation assists in transferring liquid from the pouch into the bottle's spray nozzle where the liquid is atomized in a swirl airflow and dispersed by the expelled ambient air.

The disclosure relates to a foam dispenser which includes a plastic bottle made of a flexible plastic having a bottle opening, a closure cap that seals the bottle opening and has a dispensing opening for a foam, a foam-generating device for foaming a solution including a chamber having at least one wall, at least one inlet for air in a wall of the chamber, and at least one inlet for liquid in a wall of the chamber, and at least one porous body that is arranged in the chamber, the foam-generating device being arranged in or connected to the closure cap, and a riser pipe that is arranged inside the bottle and is connected to an inlet.
