  • Patent number: 10515720
    Abstract: Arrangements are provided for “smart” functionality with “dumb” containers, such as for tracking medication use to determine adherence. An acoustic emitter such as a whistle is engaged with a container such as an eye drop bottle. An event such as dispensing medication or opening the container causes a characteristic acoustic emission, such as an ultrasonic pitch of specific frequency. The emitter may be purposefully configured to produce the emission, may operate so that the emission is a natural consequence of dispensing medication (or other event), and may operate transparently to the user. The emitter may be part of a larger remote, such as a squeezable air-filled shell with an aperture to accept the container. A cell phone or other station receives the acoustic emission, and if a processor thereof determines that the emission is characteristic of the emitter the event is recorded, transmitted, displayed, or otherwise registered.

  • Patent number: 8690025
    Abstract: A dispensing container according to the invention includes a container body having a rod-like shape. The dispensing container is therefore compact and the user can hold the dispensing container as if the user holds a pen and use the thumb, the index finger, and any other finger to apply pressure to the dispensing container so as to dispense a drug solution. A heat insulating grip is attached to the outer circumferential surface of the container body, whereby heat originating from the body temperature of a finger of the user will not be transferred to the drug solution or volatilize it. No excessive dispensing that is not intended by the user will therefore occur. Since the container body is thin and hence unlikely crashed, the user can make adjustment of the pressure applied by the thumb, the index finger, and any other finger to readily extract a single droplet.

  • Publication number: 20130233891
    Abstract: The liquid material discharge device and method discharges a liquid droplet even under a condition where discharge of a small amount of liquid material is required. The apparatus has a liquid chamber having the discharge opening through which the liquid material is discharged, an extrusion member having a plunger and a contact portion, the plunger being thinner than the liquid chamber not to contact a side wall of the liquid chamber and having a forward end portion which advances and retracts within the liquid chamber, and a collision member disposed adjacent to the extrusion member on the side opposite to the plunger and having a piston and a collision portion facing the contact portion. The collision portion collides against the contact portion such that the extrusion member is advanced at a high speed to discharge the liquid material.

  • Publication number: 20130221037
    Abstract: A credit card shaped container for a liquid, such as eye drops, saline solution, or a sanitizer. The container has a generally flat, rectangular, flexible plastic body having an inner chamber capable of storing the liquid. A conduit supplies liquid in the chamber to a dispensing orifice at an end portion of the body. A cap attached to the body and covering the dispensing orifice prevents the liquid from being dispensed until the cap is removed and pressure applied to the flexible plastic body. The cap may be hingedly attached to the body, or completely detachable from the body. The cap typically snaps over the orifice and seals the conduit closed. The container may further comprise an integral contact lens case.

    Abstract: Drop dispenser for releasing a pharmaceutical liquid in drop form, with a housing, a liquid storage and a discharge opening, which penetrates a wall of the housing and to which an outlet valve is assigned, for extracting the liquid. The discharge opening is surrounded by a drop-formation area on the outside of the housing, wherein this drop-formation area, at least in an outer region with respect to an alignment of the drop dispenser with the discharge opening pointing vertically downwards, has a shape tapering downwards and towards the discharge opening. The drop dispenser allows the release of drops with a constant size and shortens drying time.

  • Patent number: 8403176
    Abstract: The present invention relates to packaging materials for ophthalmic solutions. Difficulties with water loss in standard ophthalmic bottles are overcome in the controlled drop dispensing container of the present invention. This controlled drop dispensing container comprises a dispensing tip, a laminate tube 15, and a shoulder connecting the laminate tube 15 to the dispensing tip 7. The dispensing tip 7 comprises an inner orifice having a diameter sufficiently small to restrict flow of liquid contents of the tube to the desired level, an outer orifice 9 having a diameter sufficiently large to form a drop of the desired size from the liquid contents of the tube, where fluid communication exists between the inner orifice and the outer orifice 9. The laminate tube 15 comprises an outer polymeric layer 10, an optional first tie layer 11, a middle barrier layer 12, an optional second tie layer 13, an inner polymeric layer 14.

  • Publication number: 20120270147
    Abstract: The particulate material production method includes vibrating a particulate material composition liquid in a liquid column resonance chamber having at least one nozzle to form a standing wave in the particulate material composition liquid caused by liquid column resonance, so that droplets of the particulate material composition liquid are ejected in a droplet ejection direction from the nozzle so as to fly in a space in a flight direction; feeding a gas in a direction substantially perpendicular to the droplet ejection direction to change the flight direction of the ejected droplets; and solidifying the droplets in the space to produce a particulate material. The particulate material composition liquid includes at least a solvent and a component of the particulate material dissolved or dispersed in the solvent, and the nozzle is located at a location corresponding to an anitnode of the standing wave.
