Dropper

A package comprising a container including a body formed to include an interior product-storage, region and a neck coupled to the body and formed to include a mouth opening into the interior-product storage region,

• a lid coupled to the neck of the container and formed to include a portion of a droplet passageway therein which is arranged to extend along a longitudinal axis of the lid, the droplet passageway being adapted to communicate a droplet of fluid from the interior region to an environment surrounding the package, and
• a droplet controller coupled to the lid to move therewith and configured to provide means for controlling discharge of the droplet of fluid stored in the interior region in response to pressurization of the fluid in the interior region so that a pre-determined size of the droplet and a predetermined rate of discharging the droplet occurs when the package is in any orientation and pressure is applied to the fluid stored in the interior product-storage region,
• wherein the droplet controller includes a male control unit coupled to the lid in a fixed position relative to the lid and arranged to extend in a downward direction away from the lid toward the container along the longitudinal axis and a female control unit coupled to the lid and arranged to he in spaced-apart relationship to the male control unit to locate the female control unit between the male control unit and the container, the male control unit, female control unit, and the lid cooperate to define a flow-control passageway therebetween and the flow-control passageway is in fluid communication with the interior product-storage region and the droplet passageway, and the female control unit includes an outer surface arranged to face away from the male control unit toward the lid, a first outer passageway surface arranged to extend from the outer surface toward the longitudinal axis, and a second outer passageway surface arranged to extend away from the outer surface toward the longitudinal axis,
• wherein the flow-control passageway includes an outer section,
• wherein the outer section of the flow-control passageway includes a first outer portion arranged to extend in a downstream direction, a second outer portion arranged to extend in an inward direction toward the longitudinal axis, and a third outer portion arranged to extend in the downstream direction, the female control unit having an inner surface surrounding the male control unit,
• wherein a transition between the second outer portion and at least one of the first outer portion and the third outer portion is curved.

A closure comprising a lid adapted to couple to a neck of a container and formed to include a portion of a droplet passageway therein which is arranged to extend along a longitudinal axis of the lid and

• a droplet controller coupled to the lid to move therewith and configured to control discharge of the droplet of fluid stored in an interior product-storage region of the container in response to pressurization of the fluid in the interior region so that a pre-determined size of the droplet and a predetermined rate of discharging the droplet occurs when the closure is in any orientation and pressure is applied to the fluid stored in the interior product-storage region,
• wherein the droplet controller includes a male control unit coupled to the lid in a fixed position relative to the lid and arranged to extend in a downward direction away from the lid toward the container along the longitudinal axis and a female control unit coupled to the lid and arranged to lie in spaced-apart relationship to the male control unit to locate the female control unit between the male control unit and the container, the female control unit having a trench arranged to extend from an outer surface of the female control unit toward the longitudinal axis, the male control unit, female control unit, and the lid cooperate to define a flow-control passageway therebetween, the female control unit having an inner surface surrounding the male control unit,
• wherein the flow-control passageway includes an outer section,
• wherein the outer section of the flow-control passageway includes a first outer portion arranged to extend in a downstream direction, a second outer portion arranged to extend in an inward direction toward the longitudinal axis, and a third outer portion arranged to extend in the downstream direction
• wherein a transition between the second outer portion and at least one of the first outer portion and the third outer portion is curved.
