DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The invention and its various embodiments can now be better understood by turning to the following detailed description wherein illustrated embodiments are described. It is to be expressly understood that the illustrated embodiments are set forth as examples and not by way of limitations on the invention as ultimately defined in the claims.

Figures 1-3 illustrate a first preferred embodiment of a cap assembly 10 configured to be coupled to a container 12. It is to be expressly understood that the term "container" refers to any vessel or conduit adapted to carry or direct contents, which may be in solid, liquid or gaseous form. Such contents may be dry, wet or a mixture of both, and may be used and/or consumed by humans or other living things. Accordingly, the cap assemblies according to the invention may be used on products for pets, for example. As examples and not by way of limitation, a container may comprise a bottle, tube, hose, jar, box, can and more, in one preferred embodiment, the container 12 comprises a condiment bottle, such as a ketchup or mustard bottle. Thus, the cap assembly 10 is preferably configured to be retrofitted onto standard condiment bottles generally sold at stores.

In Figure 1 , the cap assembly 10 preferably comprises a body 20 and a closure mechanism 22. In the preferred embodiment, the cap assembly 10 is designed to provide fun and entertainment value for children or adults. Thus, the body 20 may be configured to resemble a variety of different objects, such as cartoon faces, animal faces, human faces, caricatures, body parts, fictional creatures, etc. The body 20 may comprise colors internally throughout and/or applied to the externa! surface. As an example and not by way of ϋmitation, the body may be composed of a generally softer and malleable plastic material such as polypropylene or thermoplastic material.

The body 20 defines at least one exit opening, or aperture, 24 through which dry or wet contents from the container 12 may exit. To enhance the fun and entertainment value of the cap assembly 10, the apertures 24 may be shaped as orifices of a face, such as the nostrils, ears or mouth.

When coupled to a container 12, such as condiment bottle for example, the cap assembly 10 serves as a dispenser as shown in Figure 3. The exit opening 24 is in fluid communication with the container 12 preferably through a passageway 26 defined within the body 20. The passageway 26 comprises the hollow cavity defined within the body 20 that is in fluid communication with the container 12.

In Figure 2, the body 20 comprises a connector portion 31 configured to mate with a plurality of differently sized containers having different connections. In the first preferred embodiment, the connector portion 31 may comprise an internally threaded section 33. The section 33 may comprise multiple threads for coupling to different externally threaded configurations of varying bottles. The internally threaded section 33 may be formed in the body 20 itself or in an insert 35 adapted to fit within the body 20. For manufacturing purposes, it may be preferable to form the insert 35 out of a second plastic material that is generally more rigid than the first malleable material forming the body 20. Providing internal threads on the more rigid insert 35 also facilitate a more secure coupling to the container 12. In the preferred embodiment, the internally threaded connector portion 31 is configured such that the cap assembly 10 may be retrofitted on existing spouts of conventional food and drink containers, such as condiment bottles, water bottles and the like. To increase flexibility, a kit of inserts 35 may be provided with different internal diameters and different pitches of internal threads in order to accommodate different types of botties.

In Figures 1 and 2, the closure mechanism 22 closes the openings 24 and thus seals or blocks the contents from exposure to ambient air, thereby preserving the freshness of the contents of the container 12. Thus, the cap assembly 10 not only serves as a dispenser, but also provides storage. The closure mechanism 22 can comprise any movable structure, such as a hinged arm 28, adapted to block or seal the exit opening 24, such as with a plug 29, In Figure 3, the closure mechanism 22 may comprise a tab 37 that fits into a slot 38 defined in the body 20.

Figures 4-6 illustrate a second preferred embodiment of the cap assembly 10b where elements of similar structure are designated by the same reference numerals followed by the lower case "b". In Figures 5 and 6, the second preferred cap assembly 10b comprises a snap-on connector portion 31 b which may be preferable for coupling to containers 12 having spouts or connectors with smaller diameters and/or finer externa! threads, such as containers for toothpaste, lotion, liquid soaps and cleansers, etc, In particular, the connector portion 31 b as shown in Figure 5 comprises an inner tube 40 that is configured to be inserted into the top opening of a container 12, such as a toothpaste spout, to direct contents through the passageway 26b.

In Figure 5, the inner tube 40 defines the passageway 26b which directs contents from the container to the exit aperture 24b. As an example and not by way of limitation, the inner tube 40 may have an outer diameter in the preferred range of 0.1 inches to 2 feet. A generally cylindrical outer wall 42 is concentric with the inner tube 40 and is preferably formed with axial slots 44. The concentric outer wall 42 and inner tube 40 collectively form an annular groove 46 for receiving the spout or connector of the container 12. it will be appreciated that the axial slots 44 enable the outer wall 42 to expand and contract radially and thus provide flexibility in accommodating differently sized container spouts. Axial ribs 46 are formed on the inner surface of the outer wall 42 to help grip the container spout and provide a more secure fitting. Accordingly, the snap-on connector portion 31 b provides the cap assembly 10b with a universal fitting of a variety of differently sized containers and corresponding spouts.

The closure mechanism 22b may comprise a movable arm 51 connected to the body 20b. In the preferred embodiment, the arm 51 is made rotatable by a hinge 53, such as a free hinge, formed at a base of the arm adjacent to the connection to body 20b. A stopper 55 disposed at a distal end of the arm 51 is configured to plug the exit aperture 24b and thus seal the contents therein. It is to be expressly understood that the closure mechanism 22b may comprise any structure configured to close the assembly 10b so as to prevent spoilage of the contents within the container 12. Figure 6 iiiustrates the second preferred cap assembly 10b assembled onto a container 12, such as a toothpaste container. The ribbed annular groove 46 receives the spout 57 of the container 12 while the inner tube 40 is inserted into the container 12 to enable contents therein to be directed into the passageway 26b and out the aperture 24b. The closure mechanism 22b thus provides a secure, universal fitting for a variety of container spouts regardless of whether such spouts are externally threaded or otherwise configured for mating with their original caps.

The closure mechanism 22b is configured to plug and thus close the passageway 26b to prevent the container contents from spoiling. Thus, the cap assembly 10b provides not only entertainment value, but storage capability as well. Accordingly, the cap assembly 10b can replace original caps of existing containers. Furthermore, once the container contents are depleted and the original container 12 is discarded, the cap assembly 10b can be saved and easily cleaned in order to be used for a new container having a similar or different spout configuration.

Figure 7 illustrates a third preferred cap assembly 10c having a separate detachable closure mechanism 22c. In this embodiment, elements of similar structure are designated by the same reference numerals followed by the lower case "c". In the illustrated embodiment 10c where the body 20c resembles the head of a cow, the third embodiment may be used as a cap assembly for a milk bottle container 12, for example. Here, the closure mechanism 22c comprises a cork which is not tethered to the body 20, but rather completely separate and detachable therefrom. The cork 22c, designed to resemble a corn cob for entertainment purposes, plugs the aperture 24c to close the assembly 10c.

Figures 8 and 9 illustrate a fourth preferred cap assembly 10d having an internal or self-closing mechanism, or valve, 22d. !n this embodiment, elements of similar structure are designated by the same reference numerals followed by the lower case "d." The self-closing valve 22d may comprise a plastic member having flexible pie-shaped segments 60. When the user squeezes the container 12 or otherwise causes contents to flow from the container through the cap assembly 10d, the pie-shaped segments 60 open outwardly to enable contents to exit. The pie-shaped valve segments 60 are biased to a closed position and thus return to close off the passageway when contents are no longer being forced out of the container. 12.

Figure 10 illustrates a fifth preferred cap assembly 10e having a separate screw-on topper 62. In this embodiment where elements of similar structure are designated by the same reference numerals followed by the lower case "e," the body 2Oe comprises external threads 64 formed around a base 66 of the body 2Oe. The external threads 64 are configured to mate with internal threads 68 formed in the topper 62.

Figure 11 illustrates a sixth preferred cap assembly 10f having an internal twist valve 70. In this embodiment where elements of similar structure are designated by the same reference numerals followed by the lower case "f," the body 2Of may be substantially similar to the body 20 of the first preferred embodiment shown in Figure 1 excepting the closure mechanism 22. In this embodiment 10e, the internal twist valve comprises interna! threads formed within a base 72 which is configured to be screwed onto a container. A conical spout 74 directs contents from the container to the exit opening 24f of the body 2Of. The body 2Of encloses the conical spout 74 with the exit aperture 24f aligned with an valve opening 76 at the top of the conical spout 74.

Figure 12 illustrates a seventh preferred cap assembly 10g directed for use on bottles for wine and other drinks. In this embodiment where elements of similar structure are designated by the same reference numerals followed by the lower case "g," the body 2Og resembles a human face and defines an exit opening 24g which may resemble a mouth. In this embodiment 1 Og, the closure mechanism 22g comprises a detachable cork 22g resembling a party blower. The assembly 10g may comprise a tapered pourer 80 to facilitate pouring of the beverage contents.

Figure 13 illustrates a preferred method 100 of installing a fun and/or entertaining cap assembly onto a container. The method 100 may comprise retrofitting an existing container by replacing an original cap with an entertaining cap assembly according to the invention. The method 100 may also comprise providing a new package altogether with an entertaining cap assembly according to the invention assembled onto a new container from the outset. The method 100 comprises a step 1 10 of providing a new container or removing an original cap from an existing container. Step 120 comprises providing a fun and/or entertaining cap assembly having a closure mechanism and a connector portion. The closure mechanism may comprise any variety of structures adapted to close fluid communication to the contents of the container and thus prevent exposure to ambient air. Such closure mechanisms may require manual operation, such as hinged arms with plugs or detachable corks, or not, e.g., self-closing valve. In step 130, the cap assembly is assembled or coupled to the container. This may comprise screwing the cap assembly onto an externally threaded spout, such as with condiment containers and milk bottles, or partially inserting the cap assembly into container spout using a snap-on connector. In step 140, contents from the container may be dispensed through the cap assembly, exiting the aperture defined in the body, which aperture may be configured to resemble an orifice of a face, for example. In step 140, contents of the container are stored by closing the cap assembly using the closure mechanism.
