Abstract: The tube (1) includes a connector (9) with a dispensing duct (13) which connects a dispensing opening (11) to a reservoir (3). For the dosed dispensing of a liquid from the reservoir (3) through the dispensing opening (11), a throttle insert (31) is inserted into a distal section (9b) of the connector (9) and is connected in form-fitting fashion to the connector (9). The connection of the throttle insert (31) to the connector (9) is preferably realized by a radial pressing action. The throttle insert (31) is preferably of dome-like form and delimits at least one primary throttle duct (47) which forms in the dispensing duct a constriction which limits the volume flow of the liquid from the reservoir (3) to the dispensing opening (11).

Abstract: A vessel for use in rinsing a user's nasal cavity provides a resiliently collapsible main body, a self-sealing nozzle that increases in internal pressure when the vessel is squeezed, and a check valve in the nozzle to reduce back-wash into the vessel. A collar connects the nozzle and check valve to the main body. The check valve includes a first opening that provides fluid communication between the main body and a void formed in an interior of the nozzle and may allow pressure within the nozzle to increase upon deforming the main body. A second opening may provide fluid communication between an exterior of the main body and a fluid reservoir formed in the main body. The second opening may cooperate with a valve that allows selective fluid communication between the exterior of the main body and the reservoir formed in the main body.

Abstract: The present invention relates to a bottle for packaging a liquid to be distributed drop by drop comprising a reservoir the walls of which can be reversibly elastically deformed by letting air into the container, surmounted by a liquid dispensing head comprising a dropper nozzle protruding from the bottle and an anti-bacterial filter membrane, that is partially hydrophilic and partially hydrophobic, interposed across the path of the liquid and the air, at the base of the said nozzle. In the dispensing head, the proposal is to create the nozzle by itself out of a material containing a bactericidal agent that has the effect of preventing any bacterial growth on the surface of the said nozzle on the outside of the antibacterial membrane. A porous core is advantageously positioned inside the duct through which liquid is expelled and air is admitted.

Abstract: A dispensing tip apparatus for an eye drop dispenser to administer topical ophthalmic solutions is described. The apparatus integrates an ophthalmic solution-dispensing tip with an optical gauging assembly. The tip provides continuous visual feedback about it orientation and relationship to the eye. The dispensing tip when attached to any standard topical ophthalmic solution dispensing bottle or reservoir enables the user to view a target, visually align the dispenser tip, and administer an eye drop with precision. There is also a visual feedback by which the dispenser tip is prevented from gaining too close proximity and contacting the eye, thus preventing contamination of the medication and its dispenser. The visual feedback can also contain textual or graphic information that serves as a promotional advertisement. The is assembly can be attached to the neck of an eye drop bottle or attached to the tip of an eye drop bottle.

Abstract: An eyedrop dispenser uses the natural optical lens effect of a transparent droplet formed at the tip of the dispenser to focus the image of a target disposed inside the outlet of the dispenser. The target image is viewable by the user to align the droplet with the eye when dispensing eyedrops or other liquid medication. The target image is arranged so it comes into focus just prior to when the droplet being formed at the tip of the dispenser is ready to be released from the dispenser tip. The target image is formed by an image plane indicator device located inside the dispenser on the image plane of the droplet when the user is viewing the indicator through the natural transparent lens formed by the droplet. The indicator can be a pinhole through which the liquid contents pass prior to dispensing. The pinhole is focused by the lens and formed as a magnified image by the lens effect of the droplet.

Abstract: An elongated sleeve member having an upper open end and a lower open end, and with an annular flange extending radially outwardly from adjacent the open lower end is affixed to an elongated stem member in a substantially vertical orientation for immersion in a liquid substance held in a vial. A sleeve-like surface extending between the open ends of the elongated sleeve member, and a surface defining the lower end of the sleeve and an outwardly extending annular flange provide means to remove a consistent quantity of a liquid substance, such as a liquid allergenic agent, from a storage vessel or vial, and to transfer the liquid to a receiving scarifier structure, such as a cluster of multiple scarifier points. The outer periphery and upper surface of the flange provide a means for carrying excess liquid, and the flange provides for wiping the excess liquid from the sleeve member and flange prior to dispensing a desired quantity of liquid allergenic agent onto a cluster of scarifier points.

Abstract: The hermetically sealed plastic container of the present invention has a body portion, a neck portion and a dispensing head all integrally formed. The containers furthermore preferably and advantageously are formed, filled and sealed in one continuous operation, automatically. The dispensing head is integrally molded with and atop the neck portion, and has an inside diameter which substantially corresponds with the outside diameter of the side wall of the neck portion so as to slidably and frictionally receive the neck portion within the dispensing head. A severable annular groove is provided between the neck portion and the dispensing head, with this annular groove being proportioned such that it can be severed by exerting a downward force on the dispensing head. Simultaneously, as the dispensing head is forcibly urged downwardly to sever the annular groove, the dispensing head is forcibly urged downwardly about the neck portion.

Abstract: A dispenser suitable for storing and dispensing an opthalmic product and a method of dispensing the product into an occular cavity while maintaining the dispensing orifice of the dispenser free from contact with the occular cavity is described. The dispenser comprises a container with a cavity for containing a product to be dispensed, pump means, product dispensing valve means, and pressure equalizing valve means. A positioning/guard fixedly secured to the container cooperates therewith to positively position and anthroprometically locate the dispensing orifice relative to the occular cavity. The product is dispensed into the eye without loss of product due to inadvertent closing or blinking of the eye as a result of fear of a sharp object and also places the product properly for most effective results.
