Description
- 1. Field of Invention
- The present invention relates to a small sealed container. More specifically, the present invention relates to a small sealed container that may be used to store and dispense small amount of fluids such as eye medications.
- 2. Description of Related Art
- Small containers in the general form of an eye dropper are generally used to distribute and apply drops of eye medications. Such containers are usually made as small as possible because the eye medications are expensive and only a very small amount is necessary. However, due to the surface tension of the eye medications, there is a limitation to how small of a diameter of the container may be used and still allow the eye medications to be dispensed from the container.
- If the diameter of the container is too small, the eye medications cannot be dispensed from the container due to the surface tension of the fluid. If the diameter of the container is large, the eye medications in the container can be easily dispensed. However, since the eye medications are expensive and only a few drops is necessary per use, a large diameter container is not economical or practical. Furthermore, a larger multi-use container will require preservatives for the eye medication or risk contamination. Preservatives are not desirable in eye medications and may irritate the eyes.
- There is a point where the diameter of the container is made as small as possible and yet still allows the eye medications in the container to be dispensed with ease. Most single-dose eye medications containers are made with diameters at this minimum diameter. However, even at this minimum diameter, the eye medications container is still too large and not economical for dispensing drops of eye medications. Much more eye medications than necessary for a single use must still be filled in this minimal sized container or the container will have a large void that appears to be left from evaporated eye medications.
- Although a smaller diameter container is desirable, it has not been possible due to the physical phenomenon of surface tension of the eye medications that limits how small a diameter the container may have. The present invention is a simple yet effective means to allow a very small diameter container to be used for dispensing drops of eye medications efficiently and economically.
- The present invention is a small slender container that may be used to store small quantity of fluid, such as eye medications, in a sealed environment and easily dispenses the fluid as desired. The content of the slender container is completely sealed and will not leak or evaporate from the container. The slender container is a small diameter squeezable slender container with a movable member enclosed within the slender container. The movable member enclosed within the slender container disrupts the surface tension of the fluid and allows the fluid to flow easily from the small diameter slender container when squeezed. Virtually all of the enclosed fluid will be extracted from the container with no fluid remaining in the container.

An opening means 4 in the form of a score on theelongated housing 2 is located at a reduced section near one end of theelongated housing 2. The opening means 4 may alternatively be a frangible section, a thin walled section, a twist off cap, or other similar means. Anelongated member 5 with a smaller diameter and shorter length than theelongated housing 2 is enclosed in theelongated housing 2 and has a specific gravity greater than that of the enclosedfluid 3 such that theelongated member 5 is movable relative to the enclosedfluid 3 and will sink to the bottom of the enclosedfluid 3. In the preferred embodiment, theelongated member 5 is a solid cylindrical shaft. Theelongated member 5 has a cross section greater than that of the opening resulting from operating theopening means 4 such that after theopening means 4 is operated to open theelongated housing 2, theelongated member 5 will not protrude from the resulting opening. When theelongated housing 2 is inverted, theelongated member 5 will move down and enable thefluid 3 to overcome its surface tension to also move down along with theelongated member 5 towards the bottom of the invertedelongated housing 2. - The
fluid 3 is sealed within theelongated housing 2 until released through the opening means 4. When the container enclosingmovable component 1 is opened by the opening means 4, inverted so that the opened end is directed downward whereby both thefluid 3 and theelongate member 5 moves towards the opening, and squeezed, thefluid 3 in theelongated housing 2 will be released from theelongated housing 2 in controlled drop forms. In the preferred embodiment, the length of theelongated member 5 is only slightly shorter than theelongated housing 2 such that the movement of theelongated member 5 towards the opening is relatively small thereby preventing forced ejection of thefluid 3 from theelongated housing 2 due to the movement of theelongated member 5. Virtually all of the enclosedfluid 3 in theelongated housing 2 will be extracted from theelongated housing 2 after just a few squeezes of theelongated housing 2. -
FIG. 3 shows another embodiment of the container enclosingmovable component 1 wherein theelongated member 6 enclosed in theelongated housing 2 is a hollow tube with a diameter smaller than the inside diameter of theelongated housing 2 but greater than the opening at theopening means 4. The hollow tube is slightly shorter than theelongated housing 2 and will not exit theelongated housing 2 from the opening after theelongated housing 2 is opened. Furthermore, the hollow tube has a specific gravity greater than that of the enclosedfluid 3 such that the hollow tube is movable relative to the enclosedfluid 3 and will sink to the bottom of the enclosedfluid 3. -
FIG. 4 shows another embodiment of the container enclosingmovable component 1 wherein theelongated housing 2 enclosed twomovable components movable component 7 has a specific gravity greater than the enclosedfluid 3 such that it will sink to the bottom of thefluid 3. The othermovable component 8 has a specific gravity smaller than the enclosedfluid 3 such that it will float to the top of the enclosedfluid 3. The lengths of themovable components component 7 is sunk at the bottom of theelongated housing 2 and theother component 8 is floating at the top of thefluid 3, there is an overlap that will provide a continuous disruption of the surface tension of the enclosedfluid 3 from the bottom of theelongated housing 2 to the top of theelongated housing 2. -
FIG. 5 shows another embodiment of the container enclosingmovable component 1. In this embodiment, the container enclosingmovable component 1 has a squeezableelongated housing 2 with two ends that are sealed and encloses afluid 3. Anopening means 4 is located at a reduced section near one end of theelongated housing 2. Anelongated member 9 is affixed to a sealedend 10 of theelongated housing 2. Amovable member 11 with a specific gravity greater than that of the enclosedfluid 3 such that themovable member 11 is movable relative to the enclosedfluid 3 and will sink to the bottom of the enclosedfluid 3. In the preferred embodiment, themovable member 11 is a ring surrounding theelongated member 9. Themovable member 11 may alternatively be a sphere with a specific gravity greater than that of the enclosedfluid 3. When theelongated housing 2 is inverted, themovable member 11 will move down resulting in a disturbance in thefluid 3 and enable thefluid 3 to overcome its surface tension to also move down along theelongated member 9 towards the bottom of the invertedelongated housing 2. - Although the invention has been described in terms of particular embodiments and applications, one of ordinary skill in the art, in light of this teaching, can generate additional embodiments and modifications without departing from the spirit of or exceeding the scope of the claimed invention. Accordingly, it is to be understood that the drawings and descriptions herein are proffered by way of example to facilitate comprehension of the invention and should not be construed to limit the scope thereof.
