Abstract
A beneficial agent dispensing device comprises a dispenser body comprising a pressure chamber and at least one dispensing port. A flexible primary container stores the beneficial agent contained within the body. The arrangement is such that pressure in the pressure chamber depress the flexible primary container to expel the beneficial agent through the dispensing port. The beneficial agent dispenser can be configured to deliver the beneficial agent intranasally.
Core Innovation
A beneficial agent dispensing device includes a primary container storing a beneficial agent and a dispenser body associated with the primary container. The dispenser body comprises a pressure chamber and a dispensing port, and applying a pressurized fluid in the pressure chamber causes penetration of the primary container and applies the pressurized fluid to the primary container to flex the primary container so the beneficial agent is expelled through the dispensing port.
The dispensing port is fixedly attached to the dispenser body to prevent motion of the dispensing port relative to the dispenser body. The dispensing port further comprises a fluid pathway providing fluid communication between an interior of the dispenser body and an external environment prior to pressurization, defining a fixed dispensing port arrangement in a pressure-chamber-driven expulsion device.
The described configurations include an intranasal beneficial-agent dispensing device using a flexible primary container in a pressure chamber. A pressurized-fluid source provides activation that depresses the primary container and expels drug through a fixed dispensing port, with a described example using a rupturable membrane in a pressure source actuated by a handle and rupturing pin.
Usability-related structures include a telescopic body and a tethered cap arrangement that prevents cap removal until an extended configuration. The example intranasal configuration includes a nasal applicator arrangement, including a tube penetrating the container, and an activation and return approach involving venting and an optional bleed hole for pressure-chamber behavior.
Claims Coverage
The document provides one independent claim for a beneficial agent dispensing device, refined by dependent claims adding a pressurized-fluid source, activation mechanism, pressure control via a bleed hole, dispensing-port structures, and usability features for cap handling and coverage.
Pressurized fluid-driven flexing and expelling through a fixed dispensing port
A dispenser body associated with a primary container comprises a pressure chamber and a dispensing port, wherein applying a pressurized fluid in the pressure chamber causes penetration of the primary container and applies the pressurized fluid to the primary container to flex the primary container and expel the beneficial agent through the dispensing port.
Fixedly attached dispensing port to prevent motion relative to the dispenser body
The dispensing port is fixedly attached to the dispenser body to prevent motion of the dispensing port relative to the dispenser body.
Fluid pathway providing fluid communication to the external environment prior to pressurization
The dispensing port comprises a fluid pathway providing fluid communication between an interior of the dispenser body and an external environment prior to pressurization.
Compressed gas cartridge with a rupturable membrane and a rupturing pin
A pressurized fluid source comprises a compressed gas cartridge with a rupturable membrane and a rupturing pin.
Activation mechanism with handle and horizontal plate to rupture the rupturing pin
An activation mechanism with a horizontal plate and a handle is configured such that when actuated, it drives a compressed gas cartridge to rupture a rupturing pin.
Bleed hole to regulate pressure inside the pressure chamber
The device further includes a bleed hole configured to regulate pressure inside the pressure chamber.
Dispensing port comprising jet nozzle, spray nozzle, or topical applicator
The dispensing port comprises at least one of a jet nozzle, a spray nozzle, or a topical applicator.
Retractable second body that covers the cap and prevents cap removal until extended
A second body retracts to cover the cap and prevent its removal, while an extended configuration permits removal of the cap.
Overall claim coverage centers on a pressure-chamber dispensing device where pressurized fluid penetrates and flexes a primary container to expel a beneficial agent through a fixed, body-attached dispensing port, with a port fluid pathway providing external fluid communication prior to pressurization; dependent refinements add specific pressurized-fluid hardware, an activation mechanism, pressure regulation via a bleed hole, dispensing-port output structures, and cap and telescopic usability features.
