Abstract: An aerosol tip mechanism for an aerosol-type dispenser for dispensing liquid content has a flexible outer shell, a rigid cap portion composed of lower and upper portions, and a rigid nozzle portion having a rigid shaft received within the outlet portion of the flexible outer shell. The rigid shaft interfaces the outlet portion of the outer shell, forming a first normally-closed one-way valve. The lower and upper portions of the rigid cap portion form boots adapted to receive an outlet portion of the flexible outer shell, the boots thereby constraining a lateral motion of the outlet portion of the outer shell, and symmetrically centering the outlet portion around the rigid shaft of the nozzle. The rigid nozzle portion includes a plurality of liquid channels for delivering liquid from a reservoir to a swirling chamber defined within the rigid cap portion, which liquid channels are configured to minimize energy losses of the liquid and promote a more homogeneous fluid particle size in the dispensed aerosol. The aerosol tip mechanism provides for long-term sterility of the stored fluid, which in turn allows for preservation of the sterility of non-chemically preserved formulations, which may be in the form of suspension or liquid gels.

Abstract: An apparatus is used to apply medicament to an eye and stores the medicament in a medicament chamber. A nozzle is coupled in fluid communication with the medicament chamber and is formed by an outer nozzle portion and an inner nozzle portion received within the outer nozzle portion. A seam is formed by the interface of the inner nozzle portion and the outer nozzle portion and is normally in a closed position to prevent the passage of medicament through the nozzle. The seam opens in response to the flow of medicament of sufficient pressure into the seam to permit the passage of medicament through the nozzle for release into the eye.

Abstract: A nozzle mechanism for generating an aerosol-type liquid discharge is provided, which nozzle mechanism ensures one-way movement of liquid during discharge and also has a substantially zero "dead volume" at the tip of the nozzle. The nozzle mechanism includes a flexible nozzle portion with an outlet and a fluid channel, a rigid shaft received within the flexible nozzle portion, and a rigid housing surrounding the flexible nozzle portion and exposing the outlet. The rigid shaft interfaces the outlet to form a first normally-closed, one-way valve, as well as to define a swirling chamber for collecting the liquid which has been channeled from the liquid reservoir, prior to being discharged via the outlet. The outlet has a tubular wall with thickness that decreases along the elongated axis of symmetry for the outlet toward the tip of the outlet. The fluid channel is circumferentially positioned within the flexible nozzle portion to create swirling action of the liquid delivered to the swirling chamber. Once the pressure on the swirling liquid reaches a threshold pressure sufficient to radially deform the portion of the outlet forming the first normally-closed valve, the liquid in the swirling chamber is discharged through the outlet. The nozzle mechanism is coupled to a flexible body portion which has a substantially tubular shape and a wall thickness which decreases from the bottom of the body portion toward the flexible nozzle portion. The rigid shaft received within the flexible nozzle portions extends down into the flexible body portion so that a second portion of the rigid shaft interfaces the flexible body portion to form a second normally-closed, one-way valve in the fluid communication path between the liquid reservoir and the swirling chamber.
Abstract translation: 提供了一种用于产生气溶胶型液体排出口的喷嘴机构，该喷嘴机构确保了排出期间液体的单向移动，并且在喷嘴的尖端处也具有基本为零的“死体积”。 喷嘴机构包括具有出口和流体通道的柔性喷嘴部分，容纳在柔性喷嘴部分内的刚性轴以及围绕柔性喷嘴部分并暴露出口的刚性壳体。 刚性轴将出口接合以形成第一常闭单向阀，并且在通过出口排出之前，限定用于收集已经从液体储存器引导的液体的旋转室。 出口具有管状壁，其厚度沿着用于出口朝向出口的尖端的细长对称轴线减小。 流体通道周向地定位在柔性喷嘴部分内，以产生输送到旋转室的液体的旋动作用。 一旦旋转液体上的压力达到足以使形成第一常闭阀的出口的部分径向变形的阈值压力，则旋转室中的液体通过出口排出。 喷嘴机构联接到柔性主体部分，其具有基本上管状的形状和从主体部分的底部向柔性喷嘴部分减小的壁厚。 容纳在柔性喷嘴部分内的刚性轴向下延伸到柔性主体部分中，使得刚性轴的第二部分接合柔性主体部分，以在液体之间的流体连通路径中形成第二常闭单向阀 水库和旋转室。

Abstract: An apparatus for applying medicament to an eye has an inner casing and an outer casing coupled to the inner casing and moveable relative thereto. An eyecup is supported on one end of the inner casing. The eyecup defines a surface shaped to conformably engage the facial tissue surrounding an eye. An ocular vial supported with the inner casing. The ocular vial holds medicament for release into an eye. An eyelid displacing member is coupled to the outer casing and slideably mounted through the inner casing. The eyelid displacing member includes a depresser tab adapted to engage the facial tissue below an eye. The depresser tab engages the facial tissue upon moving the outer casing toward the inner casing, thus displacing the lower eyelid to expose the ocular cul-de-sac. A dispensing member is supported by the outer casing. The dispensing member is adapted to actuate the ocular vial upon moving the outer casing toward the inner casing, to release medicament onto the exposed ocular cul-de-sac of the eye.

Abstract: An occular treatment apparatus for applying liquid medicament from a reservoir is provided. The apparatus includes a tubular housing with a first open end adapted to conform to the shape of the facial area surrounding the eye socket. The housing is constructed and arranged to receive, hold and position a reservoir containing the liquid medicament. A sighting opening is included on the housing to properly orient the eye and distract the user from the drops of liquid medicament to be introduced into the eye. An eyelid displacement mechanism is supported on the first open end of the housing at a position diametrically opposed to the sighting opening. The displacement mechanism is adapted to evert the lower eyelid and expose the cul de sac. This combination of an eye focused at the sighting hole and an everted lower eyelid exposes the cul de sac so that drops of medicament dispensed into the eye will more easily and directly be applied at or near the cul de sac where it is temporarily retained to increase the length of time the medicament will medicate the eyeball. In a further embodiment of the instant invention, the lower eyelid displacement mechanism will simultaneously cause drops of to be emitted from the reservoir as the cul de sac is everted to facilitate application of the drops of liquid medicament.

Abstract: A dispenser has a body with a variable-volume storage chamber for storing substance, and a dispensing portion defining a dosage chamber in fluid communication with the storage chamber. A first valve includes a valve seat and a flexible valve cover seated thereon defining a normally-closed fluid-tight seam therebetween. The valve cover relative to moves from the valve seat to allow substance through the seam and out of the dispenser. A second valve allows substance from the storage chamber into the dosage chamber and substantially prevents flow from the dosage chamber into the storage chamber. An actuator is manually movable between (i) a first non-actuated position, and (ii) a second actuated position extending into the dosage chamber for compressing a dose of substance therein, dispensing substance through the first valve. The elasticity of the actuator causes it to return to the first non-actuated position upon manually releasing the actuator.

Abstract: A vial for storing multiple doses of a substance to be dispensed into one or more syringes or other delivery devices. The vial has a body, a variable-volume storage chamber within the body for storing multiple doses of the substance therein, and a one-way valve connectable in fluid communication with a syringe or other delivery device. The one-way valve is moveable relative to the body between first and second positions (i) one of which permits the valve to open so that substance from the variable-volume storage chamber can flow therethrough and into the syringe or other delivery device connected in fluid communication therewith, and (ii) one of which prevents the valve from opening.
