Field of the Invention

This invention relates in general to containers for cosmetics, and in particular to a fitment for preventing leakage of cosmetics from such containers.

Description of the Prior Art

Liquid makeup and other viscous cosmetics are often stored in specialized cosmetics containers. These containers typically include a reservoir for storing the cosmetics and an applicator, for example a brush, for allowing a user to apply the cosmetics. In certain containers, the applicator is affixed to the cap of the container, whereby the user grasps the cap, dips the applicator into the reservoir until a sufficient amount of makeup is on the applicator, and then removes the applicator and applies the makeup. Alternatively, the applicator can be affixed to the container body itself, whereby, for example, the user squeezes the container to force makeup out of the reservoir and directly into or onto the applicator.
In the case where the applicator is affixed directly to the container body, it is not uncommon for leakage to occur at or near the location where the makeup passes from the storage reservoir into the applicator. This leakage can occur either during use of the device, when the cap has been removed from the container, or when the device is not in use and the cap is affixed to the container. When the cap is affixed to the container, leaking makeup can accumulate under the cap, such that once the cap is removed from the container, the accumulated makeup will spill out.
Various types of cosmetics containers have been proposed to prevent or reduce this leakage. Certain of these containers utilized both a cap and a sealing mechanism, for example, a stopper, to prevent leakage. The sealing mechanism was designed to prevent potential leakage, and any makeup that did leak past the sealing mechanism was subsequently caught in the cap. However, a user had to perform multiple steps in order to access the makeup in these containers. For example, the user had to first remove the cap, and then disengage the stopper, in order to initiate flow of makeup from the device. Multiple steps were also needed to close and store the container, in that the user had to first engage the stopper, and then place the cap on the container, in order to provide maximum leakage protection when the device was not in use. Further, the sealing mechanisms were not effective to prevent leakage at the location between the storage reservoir and the applicator, and the sealing mechanisms were often easily removable from the container, which increased the likelihood of leakage.
Prior to the development of the present invention, there has been no fluid dispenser assembly for use in storing and dispensing makeup and other cosmetics which: effectively prevents leakage of makeup from a cosmetics container; provides an improved seal at the location between the storage reservoir and the applicator of a cosmetics container; utilizes a sealing mechanism which is not easily removable from the cosmetics container; allows a user to remove the cap from a cosmetics container and access makeup from the reservoir in a single step; and allows a user to place the cap on a cosmetics container and restrict access to makeup from the reservoir in a single step.
WO 88/04148 discloses a device for storing, dispensing and applying nail enamel and like fluids. A container adapted to store the fluid is provided with a valve, the inner member of which has an applicator (e.g. bristles) mounted on its outer end. A closure cap has an interior adapted to receive the applicator and serves to hold the valve in the closed position, and to open the valve as the cap is removed. One or more channels traverse the length of the valve stem. When the valve is in the open position, fluid is made to flow through the channels and onto the applicator from which it can be transferred to fingernails and like substrate to be treated. Interacting stops on the valve stem and housing limit the distance which the valve stem can travel when the closure cap is removed.

Detailed Description

FIG. 1 shows the components of a fluid dispenser assembly 10 according to an embodiment of the present invention. The assembly 10 is preferably used for dispensing cosmetics in the form of a liquid or viscous material. Assembly 10 includes a vessel or container body 11 which stores the cosmetic material. Neck 14 extends upward from vessel 11 and typically has a smaller diameter than vessel 11. Neck 14 has a hollow interior. In one embodiment, neck 14 has conventional external screw threads (not shown) so that a cap 16 with corresponding internal screw threads (not shown) can be attached to vessel 11. In alternative embodiments, a friction or snap-on fit between cap 16 and neck 14 may be employed. Near its upper end, neck 14 has a band 18 that protrudes inward and has a flat downward facing shoulder surface 20 and a conical upward facing shoulder surface 22. In a preferred embodiment, downward facing shoulder surface 20 is perpendicular to the axis of neck 14, and upward facing shoulder surface 22 is at an angle of 45 degrees relative to the axis of neck 14.
Assembly 10 further includes a fitment 23 having an insert 24 with a base 30 disposed therein and a dispenser 34. Preferably, insert 24 has a cylindrical outer chamber 25 and a hollow annular interior. In one embodiment, insert 24 is formed of a plastic or other similar material. Insert 24 has a downward facing shoulder surface 26 disposed within the interior wall of its outer chamber 25. Insert 24 has an outer diameter that is smaller than the interior diameter of neck 14 so that insert 24 may be fitted within neck 14. The conical upward facing shoulder surface 22 of band 18 on neck 14 allows insert 24 to slide into neck 14. Insert 24 has an outward facing groove 28 formed in the surface of its outer chamber 25. Groove 28 is sized so that band 18 of neck 14 will fit within groove 28 when insert 24 is disposed within neck 14. Insert 24 has a base 30 disposed therein. Base 30, which can be more clearly seen in FIG. 2, is preferably cylindrically shaped, and contains a hole 32 at or near its center. Hole 32 is approximately 1.0 mm in diameter, or about the same diameter as a standard sewing needle. Base 30 is preferably formed of a soft elastic material, for example silicone or rubber.
Dispenser 34 preferably has a base 35, a cylindrical outer chamber 36 and a hollow interior. In one embodiment, dispenser 34 is formed of a plastic or other similar material. Dispenser 34 has a band 37 disposed at the upper portion of chamber 36 that protrudes outward and has a flat upward facing shoulder surface 38 and a conical downward facing shoulder surface 40. In a preferred embodiment, upward facing shoulder surface 38 is perpendicular to chamber 36, and downward facing surface 40 forms a 45-degree angle. Dispenser 34 has an outer diameter that is smaller than the interior diameter of insert 24 so that dispenser 34 may fit within insert 24. The sloped downward facing shoulder surface 40 of band 37 allows dispenser 34 to slide into insert 24.
In one embodiment, a dispensing tube 42 is fitted within, and extends upward from, base 35 of dispenser 34. Tube 42 is preferably constructed of a plastic or other similar flexible material. Applicator 43, for example a brush, is fitted within and extends upward from dispenser 34 and surrounds tube 42. In one embodiment, applicator 43 is at least partially surrounded by a sheath 45. Sheath 45 is preferably constructed of clear plastic or some other similar material, and keeps applicator 43 in place. Cosmetic is able to flow into tube 42 from hole 32 in base 30 and out of at least one opening 46 in tube 42. In another embodiment, the cosmetic flows directly from an aperture in dispenser 34 without the use of a dispensing tube.
Applicator cap 16 is preferably cylindrical and has an annular interior. Cap 16 has at least one engagement member 44 that extends downward within the interior of cap 16. In one embodiment, the member 44 extends from a top 46 of cap 16. In a preferred embodiment, engagement member 44 is a cylindrical wall with a hollow annular interior that fits over and covers brush 43 and tube 42 when cap 16 is disposed upon vessel 11. Alternatively, engagement member 44 may be a plurality of arms that extend downward within the interior of cap 16. In certain embodiments, engagement member 44 may have a friction reducing element 47, for example padding, at its lower end for contact with surface 38 of dispenser 34.
In FIG. 3, cap 16 has been removed from assembly 10. Insert 24 is disposed within the annular interior of neck 14 of vessel 11. Band 18 of neck 14 is disposed within groove 28 of insert 24 so that insert 24 cannot easily be pulled out of, or removed from, vessel 11. Dispenser 34 is disposed within the interior of insert 24. An outer portion of upward facing shoulder surface 38 of band 37 contacts and is engaged with downward facing shoulder surface 26 of insert 24 so that dispenser 34 cannot easily be raised and pulled out of insert 24. Base 35 of dispenser 34 contacts and is engaged with base 30 of insert 24 to form a fluid tight seal. The seal prevents cosmetics from leaking out around base 35 of dispenser 34 when the cosmetics are exiting hole 32 and flowing into dispenser tube 42.
Preferably, cosmetics can flow from vessel 11, out of hole 32, through dispensing tube 42, out of opening 46, and into applicator 43. In one embodiment, cosmetic flow to applicator 43 can be aided and enhanced if the user applies pressure to vessel 11. Vessel 11 is preferably formed of a flexible and resilient material such as polypropylene, so that it may be easily squeezed by the user and is capable of returning to its original shape.
As illustrated in FIG. 4, when assembly 10 is not in use, cap 16 will typically be placed over applicator 43 to protect applicator 43 from dust and other contaminants. As cap 16 is being lowered and approaches full engagement with vessel 11, the bottom end of engagement member 44 contacts an exposed portion of upward facing shoulder 38 on band 37 of dispenser 34. Member 44 pushes down and places pressure upon band 37 and forces dispenser 34 downward into increased engagement with base 30 of insert 24. As a result of the increased force, base 30 of insert 24 will compress and stretch downward. Preferably, the pressure placed upon base 30 by the increased force will result in about 0.5 mm of stretching. This stretching causes the sides of hole 32 in base 30 to come together, and hole 32 will close substantially or completely shut. As a result, the flow of cosmetics from vessel 11 into dispensing tube 42 is prevented. Further, base 35 of dispenser 34 engages base 30 of insert 24 in one or more locations to a significant degree and forms a fluid tight seal that further blocks any small flow of cosmetic from vessel 11 from leaking from assembly 10.
