摘要:
A dispenser has a housing, and a variable-volume storage chamber formed within the housing and defining a substantially fluid-tight seal between the chamber and exterior of the housing for storing a substance to be dispensed. A piston is mounted within the housing, and a one-way valve is mounted within the housing and coupled in fluid communication with the variable-volume storage chamber. A compression chamber is coupled in fluid communication between the piston and one-way valve, and at least one of the piston and valve is manually depressible relative to the other between (i) a first position in which the piston is located at least partially outside of the compression chamber for permitting substance to flow from the variable-volume storage chamber into the compression chamber, and (ii) a second position in which the piston is located at least partially within the compression chamber for pressurizing substance within the compression chamber above a valve opening pressure and, in turn, dispensing substance through the one-way valve and out of the dispenser.

Apparatus for molding and filling a device having a body defining an opening in communication with an interior chamber for receiving a substance therein, and a closure including a penetrable and resealable portion for sealing the opening and substance received in the device. A mold includes within the aseptic chamber plural mold cavities shaped to form the closure and body, and substantially sterile surfaces extending about and contiguous to the peripheries of the mold cavities. An assembly device including end-of-arm tooling having an engaging portion engageable with each of the body and closure is movable relative to the mold to engage and de-mold the substantially sterile closures and bodies from the mold cavities. Flexible barriers are coupled to the mold and the tool to substantially prevent the passage of contaminants from the molding machine and tool therethrough.

A dispenser is provided for the delivery of controlled, metered amounts of any of numerous different substances to humans or animals, such as medicaments, pharmaceuticals, cosmetics, and food products, or to deliver materials that may react upon exposure to air, such as glue. Means are provided in the dispenser to effect controlled delivery of a pre-determined amount of the substance contained in the dispenser. A one-way valve is provided to hermetically seal the portion of the dispenser containing the substance to be dispensed.

An ophthalmic delivery device includes a body defining a fluid reservoir and a pump in fluid communication with the reservoir. The delivery device also includes a nozzle that includes a dosage chamber for holding a dosage of fluid, a valve seat, and a valve cover. The valve cover extends about the valve seat and forms an interface therebetween and the valve seat includes an outlet aperture. The interface is in fluid communication with the outlet aperture and the dosage chamber, and at least part of the valve cover is movable between (i) a closed position with the valve cover engaging the valve seat to close the interface and form a fluid-tight seal therebetween, and (ii) an open position with at least part of the valve cover spaced away from the valve seat in response to fluid flowing through the outlet aperture at a pressure greater than a valve opening pressure to allow the passage of pressurized fluid therebetween. The valve seat and the valve cover are dimensioned to dispense the dosage of fluid through the interface at a velocity of equal to or less than 6 meters per second.

A syringe and a reconstitution syringe are provided for the delivery of controlled doses of any of numerous different sterile substances, such as vaccines, medicaments, pharmaceutical preparations, cosmetics, and food products. A plunger of the syringe defines a resealable stopper frictionally and slidably received within a hollow syringe body for dispensing the medicament or other substance through a dispensing tip of the syringe upon movement of the plunger. The resealable stopper defines a heat-sealable portion to allow the stopper to be penetrated by a needle or other filling device to fill the syringe with a medicament or other substance, and in turn allow the hole remaining upon withdrawal of the needle to be heat sealed by transmission of laser energy thereon. A reconstitution syringe defines within a syringe body plural compartments, wherein each compartment stores a respective component of a multi-component medicament or other preparation.

A flexible pouch defining a variable volume storage chamber and one-way valve assembly for aseptically storing a substance, dispensing multiple portions of the stored substance therefrom in cooperation with a pump, and maintaining substance remaining in the pouch in an aseptic condition sealed with respect to ambient atmosphere. The one-way valve includes a valve seat and elastic valve cover portion overlying the valve seat forming an interference fit therewith defining a normally-closed seam therebetween. The valve portion is movable radially between (i) a normally closed position with the valve portion engaging the valve seat, and (ii) an open position with at least a segment of the valve portion spaced radially away from the valve seat to allow substance from the storage chamber through the valve opening. The one-way valve maintains substance remaining in the variable-volume storage chamber in an aseptic condition sealed with respect to the ambient atmosphere.

Disclosed is a container and method for filling same. The container includes a thermally resealable portion that is fusible in response to thermal energy, and a container body having a sealed empty chamber in fluid communication with the resealable portion for receiving therein a substance. The container also includes a base, a mid-portion, and an upper portion axially spaced from the base on an opposite side of the mid-portion relative to the base. Each of the base and upper portion define a laterally-extending dimension greater than a maximum laterally-extending dimension of the mid-portion. The method of filling the container includes penetrating the resealable portion with an injection member and introducing a substance into the chamber, withdrawing the injection member while engaging the base of the body to substantially prevent axial movement of the body, and applying thermal energy to the resealable portion to thermally fuse the penetrated region thereof.

A device for storing and dispensing a substance includes a storage chamber for the substance. The container includes a passageway in fluid communication with the storage chamber. The container includes a pierceable wall located on an opposite side of the passageway relative to the storage chamber. The device includes a one-way valve assembly including a piercing portion. At least one of the piercing portion and the pierceable wall is movable relative to the other between a first position wherein the pierceable portion is not piercing the pierceable wall, and a second position wherein the pierceable portion is piercing the pierceable wall allowing the flow of substance from the storage chamber. A removable member is disposed intermediate the valve and the container that prevents movement of at least one of the piercing portion and pierceable wall to the second position until the removable member is removed.
