A flow guide device of a spray container which comprises a bottle, a nozzle having a flow guide pipe and a straw is configured to be connected between the flow guide pipe and a suction pipe. The flow guide device includes a connecting pipe, a check valve and a check ball. The connecting pipe is connected with the flow guide pipe, which has a plurality of back flow passages and forward flow passages formed on the inner edge thereof. The check valve is arranged between the connecting pipe and the flow guiding pipe. The check ball is arranged in the connecting pipe and located on the port of the straw. When the spray container is in an inverted state, the liquid enters the connecting pipe, the one-way valve and the flow guide pipe from the backflow channel, and the check valve, wherein the flow guide pipe through the back flow passages is finally sprayed out. Accordingly, the flow guiding device has a simple structure and is convenient to assemble and capable of reducing the overall manufacturing costs.

A fluid dispenser with a fluid pump for dispensing fluid on movement of an actuator, and an air pump for delivering a stream of air through at least one sound generator on movement of the actuator. The sound generator produces at least two sounds as the actuator is moved from a first position to a second position, with each sound produced in a different time period during a cycle of operation, or differing from the other sound in respect of one or more detectable sound characteristics, such as duration, frequency, temporal alignment, amplitude, and/or timbre. The time period of each sound is a function of the relative location of the actuator between the first and second positions.

A foam discharge container is a foam discharge container for discharging foam in response to a pushing operation, and includes a discharge port which is opened in a direction opposite to a pushing direction of the pushing operation and discharges foam, and a pushing portion that keeps the distance between a discharge target body receiving foam and the discharge port constant.

A trigger sprayer is made from a single grade of polymer capable of being reused as post consumer resin. The design allows for upright and inverted actuation. A pre-compression diaphragm ensures that dispensing stroke delivers a complete and uniform amount of fluid.

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.

An exemplary refill unit for an dispenser includes a container for holding a liquid. The container has bottom side with a neck extending from the bottom side. A pump is connected to the neck of the container. The pump has a liquid pump portion that has a liquid pump inlet. The liquid pump inlet is located above the bottom of the container. A shroud is located over the liquid pump inlet and extends downward toward the bottom of the container. An air bleed valve is included and located in the top of the shroud.

The present disclosure relates to a two-way pumping device for consumption of a residual amount of a liquid. The two-way pumping device includes a vessel, a body portion including first and second chambers for storing a liquid, a suction pipe extending to the outside of the body portion, a first bearing for opening and closing the suction pipe, a pump portion including a head portion protruding outside the body portion, a first piston slidably moving in the first chamber, a second piston slidably moving in the second chamber, a first discharge portion that discharges a fluid in the first chamber to the outside, a second discharge portion that discharges a fluid in the second chamber to the outside, a spring that applies an elastic restoring force to the pump portion, and a suction portion capable of causing a liquid to flow into the second chamber.

The present invention is a device for dispensing a mixture of a first fluid and a second fluid, suited to be applied to a container holding said fluids. The device comprises a mixing chamber for these fluids, a suction tube suited to draw the second fluid in order to convey it into the mixing chamber and a tank-chamber arranged between the suction tube and the mixing chamber. The device also deviates a quantity of the first fluid coming from the suction tube towards the tank-chamber.
