A dispenser for containing and dispensing substances such as fluids, viscous substances and/or adherent substances. The dispenser has a flexible bag adapted to contain a substance to be discharged, and a one-way output nozzle that is in sealed communication with the interior of the bag for discharging the contents of the bag. The dispenser has a receptacle, with the bag being arranged and sealed within the receptacle thereby trapping fluid between the exterior of the bag and the receptacle. The nozzle of the dispenser is arrangeable on a surface of the receptacle and there is additionally a one-way fluid intake valve arranged on the receptacle for intaking fluid into the receptacle and around the exterior of the bag. The dispenser further has an arrangement for preventing the bag from blocking the nozzle. The contents of the bag can be emptied through the nozzle without the bag blocking the nozzle in use.

Disclosed herein is a cosmetic container including: a body part having an empty hollow shape, and provided with a cosmetic material accommodation portion therein; a supply part disposed to pass through the material accommodation portion of the body part, provided in a hollow tube shape, and configured such that an air discharge through hole is formed on one side of a partition disposed inside a hollow tube and a material introduction through hole is formed on the other side of the partition; a pressure member coupled to communicate with the entrance of the supply part at one end of the body part, and configured to inject air into the supply part; and a touch member coupled to communicate with the exit of the supply part at the other end of the body part, and configured such that a cosmetic material introduced through the material introduction through hole is transferred thereto.

A device for delivering a predetermined volume a substance within a body cavity. The device includes: at least one predefined volume sized and shaped to contain a predetermined volume the substance; a delivery end in fluid communication with a container; and at least one valve mechanically connected to the container and configurable between an active configuration in which the valve enables delivery of a volume of the substance and an inactive configuration, in which the valve prevents delivery.

A device is provided for delivering one or more substances within at least one body cavity. The device includes at least one pierceable vial comprising V.sub.sub [ml or mg] of the substances; the vial having at least one fluid discharging outlet port, configured for placement in proximity to the body cavity. The pierceable vial is configured to interface in a sealable manner with at least one pressurized fluid at volume V.sub.PF [ml] and pressure P.sub.PF [barg]. The device, upon actuation, permits the pressurized fluid to enter into the pierceable vial via the at least one fluid inlet port, entrains the substances, and delivers the substances through the fluid discharging outlet port to within the body cavity in the form of at least one selected from a group consisting of drops, droplets, stream, aerosol and any combination thereof.

A bag-in-bottle type of a squeeze dispenser comprising a housing, a cap, a flexible bag for containing fluid, and means to equilibrate atmospheric air pressure with air pressure inside the housing is disclosed. Said means include a closable air channel. The closable air channel, and the cap, may each be in an open or a closed position. When the cap is in an open position, the closable air channel is in a closed position, thus substantially locking the air inside the housing in place and allowing for fluid to be dispensed from the flexible bag upon application of pressing force on the sidewalls of the housing. When the cap is in a closed position, the closable air channel is in an open position, allowing for a flow of atmospheric air into, and out of, the dispenser housing and thereby equilibrating the air pressure inside the housing with air pressure of the atmospheric air.

The present disclosure provides devices for delivery of powder formulations and methods of manufacture and use of such devices.

The present disclosure provides devices for delivery of powder formulations and methods of manufacture and use of such devices.

A dry powder spray bottle includes a bottle body. The bottle body includes an outer bottle and an inner bottle, a piston and a one-way air inlet valve are sequentially arranged between the inner bottle and the outer bottle, a powder storage cavity is formed above the piston, and an airbag structure is formed between the one-way air inlet valve and the outer bottle. A rotating powder stirring mechanism is provided between the inner bottle and the outer bottle. A one-way valve is provided in the powder stirring mechanism, and when the head cap is pressed, the one-way valve opens, and gas in the airbag structure is delivered to the inner bottle through the one-way valve and sprayed out from the head cap together with dry powders, and a sealing mechanism which can close a powder outlet passage is provided between the head cap and the inner bottle.

An airpot beverage dispenser having a body with a beverage cavity, a lid with lower and upper lid portions, a bellows within the upper lid portion, an actuator for compressing the bellows to increase the pressure of trapped air in the bellows, a duckbill valve, a skirt valve extending fully around the duckbill valve, and a spout. The skirt valve is movable into sealing engagement with a lid lower wall to define an air flow path from the bellows to the beverage cavity, and when the pressure of the trapped air in the bellows is sufficiently increased, the duckbill valve opens and passes the trapped air to the beverage cavity to force beverage out the spout. When the spout is moved to a stored position and the dispenser is in a locked state, the skirt valve serves as a relief valve to prevent over pressure in the beverage cavity.
