Description
- 1. Field of the Invention
- The present invention relates, in general, to reusable containers for storing, transporting and dispensing materials such as medications and contact lenses. Two or more of the reusable containers may be attached to a base unit so that they can be transported and dispensed together as a set.
- 2. Relevant Background
- One conventional method for packaging contact lenses is to place them in glass vials. In glass vial packaging, the contact lenses are typically stored in 3 to 5 milliliters of a storage solution in a vial that is plugged with a silicone rubber stopper held firmly in place by a crimp capped aluminum safety seal. The aluminum caps are not easily removed, and are not designed for reuse. To reseal these vials, a new aluminum safety seal has to be crimped onto the vial using a special crimping tool.
- There are a number of problems associated with storing and dispensing contact lenses in glass vials: Because the vials are not easy to reseal, they are not a practical container for contact lens wearers to store their contact lenses between uses. Thus, contact lens wearers have to purchase separate contact lens cases while throwing the glass vials away. Also, because the vials are typically made of glass, they are easily breakable during transport and the glass shards can present a safety hazard. Still another problem with the vials is that they typically weigh much more than the contact lenses themselves and the extra weight increases shipping costs.
- Another conventional method for packaging contact lenses is to place them in blister packs. In blister packaging, the contact lenses are sealed with 1 to 2 milliliters of solution in plastic and/or foil packaging, which is torn open when the contact lens wearer is ready to wear the lens. Like glass vials, blister packs are not designed for reuse by the contact lens wearer, and are typically used to store disposable contact lenses. Thus, like for glass vials, separate contact lens cases have to be purchased by contact lens wearers for storing the lenses between uses.
- Still another conventional method for packaging contact lenses is to place them in flat packs without any solution. The contact lenses are shipped in a dry non-hydrated state in the flat packs. The contact lens wearer tears open the flat pack to access the lens and the packs are not reused. Separate contact lens cases have to be purchased by the contact lens wearer for storing the lenses between uses.
- The problems with conventional packaging for contact lenses also extend to other materials. For example, many types of medications are shipped from manufacturers in the same type of glass vials used for shipping contact lenses. Like the glass vials for contact lenses, the vials used for medications are not designed for reuse or refilling, and are simply thrown away once they are empty. Thus, there remains a need for packaging for materials like medications and contact lenses that is convenient to reuse.
- Briefly stated, one embodiment of the invention is a reusable container that includes a lid and a chamber adapted for leaktight coupling to the lid, where the chamber includes a base unit attachment to attach the chamber to a base unit, and where two or more of the reusable containers can be attached to the base unit.
- Another embodiment of the invention is a reusable contact lens container that includes a lid and a chamber to hold the contact lens adapted for leaktight coupling to the lid, and a base unit attached to two or more of the containers, where each of the containers has an opening that is attached to one or more anchor tabs that are formed on the base unit to attach the container to the base unit.
- Still another embodiment of the invention is a method of storing a material in a reusable container that includes the steps of placing said material into the reusable container and leaktightly sealing the container, sterilizing the container, and attaching the container to a base unit that holds two or more of the reusable containers, where the reusable container includes a lid and a chamber adapted for leaktight coupling to the lid, and where the chamber includes a base unit attachment to attach the chamber to the base unit.
- Additional novel features shall be set forth in part in the description that follows, and in part will become apparent to those skilled in the art upon examination of the following specification or may be learned by the practice of the invention. The features and advantages of the invention may be realized and attained by means of the instrumentalities, combinations, and methods particularly pointed out in the appended claims.

FIG. 7 shows a flowchart of method of storing material in a reusable container according to an embodiment of the present invention. - Referring now to
FIG. 1 , areusable container 100 in an open position according to an embodiment of the invention is shown. In this embodiment,lid 102 andchamber 104 ofcontainer 100 are flexibly attached to each other byflexible member 106.Flexible member 106 allows easy coupling and decoupling oflid 102 andchamber 104 while insuring these parts stay in close proximity to each other. -
Lid 102 includeslid surface 108 which may be opaque, or transparent. Whenlid surface 108 is transparent it acts as a window that allows one to view the contents ofcontainer 100 whenlid 102 is coupled to chamber 102 (i.e., whencontainer 100 is closed). Whenlid surface 108 is a window, it may be shaped to act as a magnifying lens to magnify the contents ofcontainer 100.Lid surface 108 may also include an area that is easily penetrable by a syringe needle that can extract materials held bychamber 104. -
Lid 102 may also include aseal 110 that provides a leak tight seal when coupled toflange face 122 and/orflange sidewall 124. Seal 110 may include a first surface that sealingly engagesflange face 122 and/or a second surface that sealingly engagesflange sidewall 124.Seal 110 may also extend over the surface oflid 102 to form a membrane (not shown) for needle insertion intochamber 104. - A leak tight seal is formed when the first surface of
seal 110 is compressed againstflange face 122 and the second surface is compressed againstflange sidewall 124. Sealing pressure betweenseal 110 andflange face 122 andflange sidewall 124 may be maintained bylocking container 100 in a closed position withlid lock member 118.Seal 110 may be constructed of, among other materials, rubber materials such as a non-hydroscopic, low-impurity thermoplastic vulcanizate (TPV). -
Lid 102 may also includetear strip 112 that makescontainer 100 tamper evident after being closed. In this embodiment,tear strip 112 is attached tolid 102 such that it may be irreversibly torn fromlid 102 by pulling onpull tab 114. Once a portion oftear strip 112 is torn fromlid 102, it cannot be reattached. -
Tear strip 112 includesstrip openings 116 through whichstrip lock tabs 117 are inserted whencontainer 100 is first closed. Afterstrip lock tabs 117 are inserted throughstrip openings 116,container 100 cannot be opened without tearing at least a portion oftear strip 112 away fromlid 102, providing conspicuous evidence of tampering. - Alternatively,
tear strip 112 may be replaced by a permanent seal that keepslid 102 coupled tochamber 104. In this example,lid surface 108 may include an area that is easily penetrable by a syringe needle that can extract materials held bychamber 104. -
Chamber 104 may includecavity 120 for holding a material incontainer 100. In this embodiment,cavity 120 has a concave hemispherical shape, and other shapes may be used as well, such as a convex hemisphere. Alternatively,chamber 104 may be open ended such that no closed cavity is formed. In this embodiment,container 100 acts as a cap andopen chamber 104 can be coupled to a separate container (not shown) to form a closed cavity inside the container. The closed cavity may hold a variety of materials such as food (e.g., ketchup), or medicine (e.g., aspirin). -
Chamber 104 also includesbase collar 126 in whichopening 128, a base unit attachment, is formed. Opening 128couples container 100 to a base unit (not shown) by inserting a portion of a base unit anchor tab throughopening 128. - One or more openings like opening 128 may be formed in
collar 126 to attachcontainer 100 to a base unit. For example, two openings like opening 128 may be positioned 180° apart aroundcollar 126 to match two base anchor tabs on the base unit that align with the openings. In another example, 4 openings positioned 90° apart may be formed incollar 126. -
FIG. 2 shows a cross-sectional view of a reusable container according an embodiment of the invention like the one shown inFIG. 1 .Container 200 includesseal 210 that is attached to two adjacent sides oflid 202. In this embodiment, whenlid 202 is coupled to chamber 204 afirst surface 211 ofseal 210 sealingly engagesflange face 222, and asecond surface 213 ofseal 210 sealing engagesflange sidewall 224. When the first andsecond surfaces flange face 222 andflange sidewall 224 with sufficient pressure,container 200 is leaktightly sealed. - Leak tight pressure between
seal 210 and the flange ofchamber 204 may be maintained by lockinglid 202 andchamber 204 together. In one embodiment the locking mechanism includeslid lock member 218 that engageslock tab 219 onchamber 204.Lock tab 221 may be attached tolid lock 218 to provide tamper evident protection tocontainer 200.Lock tab 221 is irreversibly torn away fromlid lock member 219 beforelid lock member 219 is disengaged fromlock tab 219 providing evidence thatcontainer 200 has been opened afterlock tab 221 was first set. In another example,lock tab 221 may act as a second lid lock after the tear strip is removed. -
FIG. 3 shows a reusable container according to an embodiment of the invention like the one shown inFIGS. 1 and 2 , but now in a closed position.

The materials may also include an anti-microbial additive or agent that kills microbes coming into contact with a surface of the reusable container. When the reusable containers are made of plastics, they may be produced by co-molding, shot molding, and/or injection molding, among other plastic molding techniques. In one embodiment, the process of making the reusable container may include using two-shot injection molding to integrally attach a seal with the lid of the container. Alternatively, the lid may be formed to accept a separate o-ring that is used to form a leaktight seal when the reusable container is closed.
- The reusable containers of the present invention may be used as packaging to store and dispense materials such as contact lenses and medications.
FIG. 7 shows flowchart steps for a method of storing materials in a reusable container according to a method of the present invention. In this embodiment of the method, the reusable container and material are obtained 602 and adecision 604 is made about whether the material can be sterilized in the containers. - A wide variety of materials may be stored, transported and dispensed in the reusable containers of the present invention, some of which should not undergo to a sterilization process. Examples of materials that may be stored by the present invention include, without being limited to, contact lenses such as soft contact lenses, rigid contact lenses, and interocular lenses, medications such as vaccines and other medicines in a liquid state, cosmetics, soap, cleaners and solvents.
- If the materials cannot be sterilized inside the container, then the empty container may be sterilized 606 before the material is added 608 to the container and the container is leaktightly sealed 610. Alternatively, if the
decision 604 goes the other way and the materials can be sterilized in the container, then the materials are added 612 to the container, the container is leaktightly sealed 614, and then the container and materials are sterilized 616. - A variety of sterilization processes may be used with the present invention. Examples include, but are not limited to, steam sterilization, ethylene oxide sterilization, and irradiation sterilization (e.g., gamma irradiation), among other sterilization processes. The particular sterilization technique selected may depend on a number of variables, including the composition and size of the reusable container and the materials being stored inside the container, among other variables.
- The sterilized and leaktightly sealed containers may be attached 618 to a base unit. Alternatively, the containers may be attached to the base unit before adding materials and/or sterilization. The containers attached to the base unit may be stored until ready for transport to a dispensing location or consumer (e.g., contact lens wearer).
- Although the invention has been described and illustrated with a certain degree of particularity, it is understood that the present disclosure has been made only by way of example, and that numerous changes in the combination and arrangement of parts can be resorted to by those skilled in the art without departing from the spirit and scope of the invention, as hereinafter claimed.
- The words “comprise,” “comprising,” “include,” “including,” and “includes” when used in this specification and in the following claims are intended to specify the presence of stated features, integers, components, or steps, but they do not preclude the presence or addition of one or more other features, integers, components, steps, or groups.
