DETAILED DESCRIPTION OF THE INVENTION


FIG. 1 is an elevation view of a container closure 101 engaged to a container 102 in an embodiment of the invention. The container may be any one of a variety of conventional beverage containers known in the art, such as, for example, an aluminum coffee container like many provided by coffee enterprises. Closure 101 in this embodiment of the invention comprises a body 103, which in this example has an internal female thread to engage a male threaded top of container 102. In alternative embodiment the closure may have a body with a male thread to engage a female threaded top of a container. In other embodiments the closure may have an interface to engage containers of other sorts, such as even paper cups and the like.


In the example shown in FIG. 1 closure 101 has two access wells 104 and 105. Access well 104 has a pivoted access element 106, that tipped up opens a path from a draw tip down through the closure into a second sealed enclosure within the outer enclosure of container 102. In this example a vapor-producing apparatus such as a vape pen is connected within the second sealed enclosure through access element 106, enabling a user to tip up element 106, and to draw vapor from the vapor-producing apparatus.


Access well 105 has a pivoted access element 107, similar in design and function to access element 106, that connects to a tubing under the closure, the tubing extending downward into any liquid, such as water or coffee, that may be carried in container 102. A user may tip up access element 107 and draw liquid through the tube and the access element as one would using a straw. There is a vent hole not shown that serves to equalize pressure. Finally, a handle 108 is provided on the closure to carry the closure and any added container.



FIG. 2 illustrates closure 101 removed from container 102, showing the second inner sealed enclosure 201, that may enclose, for example, a vapor-producing apparatus, and also a tubing 202 that extends downward, and may extend into any liquid that may be carried in a container like container 102. It should be noted that enclosure 201 is completely enclosed and sealed from liquid that may be in container 102, while tube 202 is open to the liquid, and extends downward into the liquid, which may be water, coffee or any other beverage. Tube 202 may be fashioned of a suitable polymer material.



FIG. 3 is a partial section view through closure 101, taken along a centerline of well 104 and access element 106. It may be seen in this section that well 104 is a rectangular enclosure with an open top. Access element 106 is an elongated unit of a width to fit into the width of well 104. There is a passage 303 through the length of element 106, with an opening 304a on one end and an opening 304b on the other. The end of element 106 with opening 304b has a spherical shape and opening 304b opens through this spherical shape. Access element 106 is pivoted across well 104 along an axis at the center of the spherical shape, such that a user may use tip 301 to rotate the access element around the pivot access to a stop point where opening 304b aligns with a vertical passage 309 through closure 101.


A seal element 305 locates in a passage 308 and has a concave spherical shape facing upward into well 104, and the spherical shape 302 of access element 106 rests in and rotates against seal element 305. At the rotation stop point that opening 304b aligns with vertical passage 309, a user may place lips on the end of element106 with opening 304b, and may draw on the volume into which vertical passage 308 opens below closure 101.


In addition to access to passage 309 through the passage 303 through access element 106, there is a small vent hole 311 vertically through seal element 305, and this hole communicates with a passage 312 into the volume below closure 101. A small tip 310 on the underside of access element 106 closes hole 311 when the access element is rotated to be fully within well 104. Passage 309 leads to and through a cylindrical nib 315.


A male threaded portion 314 on a lower portion of closure 101 provides for engagement of an elongated enclosure 201 (see FIG. 2) by a female thread on the top of enclosure 201. There is also a gasket 307 against which enclosure 201 seats when fully engaged by threaded portion 314. Internal female threads 313 are to engage with external male threads at the top of beverage container 102, and a gasket 306 engages a top rim of the beverage container to provide a seal.



FIG. 4 is an elevation view, in section, of inner sealed enclosure 201 engaged by internal threads to threads 314 of closure 101. Sealed enclosure 201 fully engaged by threads 314 urges against a gasket 307, also seen in FIG. 3, by which the inner volume of enclosure 201 s isolated from the volume within beverage container 102. In one embodiment of the invention an adapter 401, molder of a flexible polymer, has a circular opening on one end to connect to nib 315, and opening on the opposite end to connect to a vapor-producing apparatus 402, which may be a conventional vape pen of one of several types. When access element 106 is fully rotated to a stop to align opening 304b with passage 309 a user may draw on opening 304a to ingest vapor from vapor-producing apparatus 402. Passage 312 provides a vent to atmosphere for the volume in enclosure 201 outside the vapor-producing apparatus.



FIG. 5 is a section through closure 101 along a centerline of access element 107 in well 105. Access element 107 differs from access element 106 by the placement of a tip 507 in a position to close a vent opening 508 through a bottom surface of well 105 into the inner volume of beverage container 102. Vent opening 508 has a seal element 509 to secure a good seal when access element 107 is rotated down to close opening 508 by tip 507.


A seal element 505 similar to seal element 307 of FIG. 3 surrounds an opening to passage 506 in a bottom surface of well 105. Access element 107 has a spherically-shaped end 502 the matches a spherical shape of seal element 505 such that access element 107 may be rotated by tip 501 to align opening 504b with passage 506. Passage 506 terminates at a nib 510 to which tubing 202 connects, by virtue of tubing 202 being formed of a flexible polymer material. In an alternative embodiment tubing 202 may connect to nib 510 by a flexible tubing adapter piece. With access element 107 fully rotated to a stop and opening 504b aligned with passage 506 a user may draw on opening 504a to bring liquid up from beverage container 102, through passage 506 and passage 503, into the user’s mouth.


It will be apparent to the skilled person that the closure 101 as described above, in concert with inner enclosure 201, adapter 401 and vapor apparatus 402, and tubing 202 may selectively open and close the two separate access elements and access either vapor from vapor apparatus 402 or sips of beverage from beverage container 102.



FIG. 6 is a partially sectioned view of adapter 401 of FIG. 4, adapted to connect nib 315 and vapor apparatus 402. Region 402 is circular with circular internal passage 404, which is pushed onto nib 315 to connect to passage 309. A wider portion 408 has differently shaped internal regions 405, 406 and 407 to engage tip ends of different vapor-producing apparatus. In the example illustrated by FIG. 4 the engagement is by region 407, as the vapor-producing apparatus of FIG. 4 has a wider and flat aspect. In one embodiment adapter 401 is molded to accommodate and connect to three of the more preferred conventional vapor-producing apparatus.


In the figures and description above closure 101 is illustrated and described as having internal threads to match external threads on an upper extremity of a beverage container. In an alternative embodiment the beverage container may have an internal threaded upper region, and closure may have an externally threaded region to engage the internal threads of the beverage container. In yet another embodiment the closure may be adapted to snap fit on the upper rim of a beverage container having a plain upper rim, like, for example a paper cup.



FIG. 7 is a perspective view of a closure 701 adapted to snap onto a thin-walled beverage container 707, such as a paper cup, for example. In this example the closure has an upper body 702 that is molded of a polymer material and is substantially rigid. A lower body 703 has a relatively thin wall to allow the lower body some flexibility to engage an upper rim of the beverage container 707. A substantially rectangular well 704 is formed in the upper body, and a pivoted cover 705 engages inner walls of the well. A second well 709 is formed in the upper body and an access element 706 engages inner walls of well 709. Access element 706 is similar to access elements 106 and 107 of FIG. 2, and has an opening 708 to a channel through the length of the access element.



FIG. 8 is a cross section of closure 701 taken along a centerline that passes lengthwise through both pivoted cover 705 and access element 706. The thin-wall lower body 703 is illustrated as snapping over an upper rim of paper cup 707. In this embodiment there is a gasket seat 710 in a vertical opening through closure body 702 that presents an opening 711 that is closed by a shape of pivoted cover 705 with the pivoted cover in a downward horizontal closed position. When pivoted cover 705 is pivoted upward opening 711 is exposed, and provides an interface for a user to place the lips at the edge of the closure, tilt the beverage container and drink from the container just as a user would an open container. Opening the pivoted cover also opens a vent hole 713 that is closed by tip 712 with the pivoted cover in the closed position.


Access element 706 is pivoted within well 709 just as access elements 106 and 107 in wells 104 and 105, and access element 706 has a spherically-shaped end 716 that mates with a spherical shape of a gasket seat 717, such that access element 706 may be rotated to align opening 715 with opening 718, such that channel 720 is open through opening 718, opening 715, channel 714 and opening 708 to the outside.


In this example male threads 719 are the same as threads 314 shown in FIG. 3, such that an inner enclosure 201 may be engaged by female threads to male threads 719 just as illustrated in FIG. 4, to bear on a gasket 724. Adapter 401 of FIG. 4 may be engaged to nib 721 and to a vapor-producing apparatus 402, just as illustrated in FIG. 4.


Closure 701 is thus a dual-access container closure just as is closure 101. A user may manipulate pivoted cover 705 to drink from the paper cup, and may manipulate access element 706 to draw vapor from a vapor-producing apparatus such as apparatus 402 and others, adapted to the closure by an adapter such as that illustrated in FIG. 6.


A skilled person will understand that the embodiments illustrated in FIGS. 2 and 3 may be adapted to snap onto a paper cup, such as beverage container 707 of FIGS. 7 and 8, as shown in FIG. 8, and also that the embodiment shown in FIG. 8 might also be adapted to have a male or a female thread to engage threads of a beverage container, as described above for the embodiment illustrated by FIGS. 2 and 3.


In yet another embodiment of the invention, referring again to FIG. 2 and to FIG. 4, the adapter 401 and the vapor-producing apparatus may be removed from inside the sealed enclosure 201, and a tubing similar to tubing 202 may by connected to nib 315 to extend down into the interior of the sealed enclosure. In this arrangement one beverage may be introduced into container 102 outside the sealed enclosure 201, and a second, different beverage may be introduced into sealed enclosure 201. In this arrangement the two beverages are completely separated, and do not mix, and a user may draw one beverage from the container outside the sealed enclosure, and a different beverage from inside the sealed enclosure within the beverage container. As a simple example, one may have water in one place and vodka in another and may manipulate the access elements to imbibe one or the other.


In the embodiments described above a container closure provides two separate enclosures in the beverage container and two access mechanisms, one for each of the separate enclosures. See FIGS. 1 and 2 and descriptions in the specification above. In yet another embodiment of the invention a single access container closure is provided in a manner that a user may access the two separate enclosures with a single access mechanism in a single access well.



FIG. 9 illustrates a closure 901 with a threaded body 902 for closing a beverage container. There is a sealed enclosure 905 analogous to sealed enclosure 201 of FIG. 2. There is in addition a tube 906 that communicates directly with the internal volume of the beverage container. Body 902 has a single rectangular access well 903 with one tip-up access element 904, which is pivoted on the sides of the well at point 907. The access well and access element are devised such that a user may selectively access either the internal volume of sealed enclosure 905 or the internal volume of the beverage container.



FIG. 10 is a section view of container closure 901 taken on a vertical section plane that passes through the center of body 902, access well 903 and element 904 lengthwise. Body 902 has a female thread 1001 to engage male thread on a beverage container. In this example there is a sealed enclosure 905 that has a female thread on an upper end that engages a male thread on an extension 1002 under body 902. A gasket 1003 at the upper end of extension 1002 seals the inner volume of enclosure 905, and in this example a tube 1015 engages an extension 1004 and opens into the volume of enclosure 905. A tube 906 engages a bore in an extension 1006 and opens into the main volume of the beverage container outside of sealed enclosure 905.


A tip-up access element 904 has a cylindrical end 1008, an extension 1010 and a tab 1011 that is useful for tipping the access element. Cylindrical end 1008 is pivoted across sides of a rectangular well 903 and rests in a cylindrical seat in a bottom of the well, the seat lined by a seal 1009 such that the outside diameter surface of the cylindrical portion of the tip-up element remains sealed to body 902 as the access element is rotated.


Access element 904 has a lengthwise through channel 1012 that extends the full length of the access element. There is a tubular channel 1005 through body 902 and gasket 1009 that leads to tube 1015, and another tubular channel 1007 through body 902 and gasket 1009 that leads to tube 906. A bore 1013 leads from a bottom of access well 903 to the inner volume of the beverage container, with a seal 1014 at the upper end. Tip-up element 904 has a side tip 1016 (FIG. 11) that closes bore 1013 when the tip-up access element 904 is closed in the well as shown in FIG. 10. A side passage of bore 1013 leads to the inner volume of enclosure 905, but is not on the section plane so as to not intersect another bore or passage.



FIG. 11 illustrates the container closure of FIG. 10 with tip-up element 904 rotated such that through channel 1012 aligns with tubular channel 1005 which communicates with tube 1015. Note that tubular channel 1007 is closed with the access element thus rotated. In this position a user may imbibe a liquid in the internal volume of sealed enclosure 905.



FIG. 12 illustrates the container closure of FIG. 10 with tip-up element 904 rotated such that through channel 1012 aligns with tubular bore 1007 which communicates with the inner volume of the beverage container. In this position a user may imbibe a beverage in the inner volume of the beverage container. Given the description of FIGS. 11 and 12 it will be apparent that in this example a user may have two different beverages and access each by choice.



FIG. 13 illustrates the closure of FIG. 10 with tube 1015 removed and a vape pen 402 engaged with a flexible adapter 401 which in turn engages extension 1004 from the underside of the body, all within sealed enclosure 905. Description of adapter 401 and vape pens is provided above as well. In the example of FIG. 13 access element 904 is shown in the closed position in well 903 with channel 1013 sealed.



FIG. 14 illustrates the closure of FIG. 13 with access element 904 rotated to a position to align channel 1012 with tubular channel 1005 enabling the user to draw on vape pen 402. In this position channel 1013 is open venting the inner volume of sealed enclosure 905.



FIG. 15 illustrates the closure of FIG. 13 with the access element 904 rotated to position to align channel 1012 with tubular channel 1007 enabling the user to imbibe a liquid from the beverage container. Again, channel 1013 is open at this position providing vent to the beverage container.


In embodiments of the invention described here mechanisms are provided for aiding the user in positioning access element 904 rotationally. FIG. 16A is a partial cutaway elevation view of access element 904 pivoted across sides of well 903 at a point P which is the center point of the spherical portion 1008 of the access element. In this example there are three small 1601, 1602 and 1603 spherical indentions on a radius from the pivot point on one side of the access element to position the access element rotationally at three different positions, as are indicated in FIGS. 10-15. FIG. 16B illustrates a cutout section showing one indention 1605 in access element 904 engaging a ball 1604 urges by a spring 106 in a bore in one side of well 903. Ball 1605 engages each of the three indentions 1601, 1602 and 1603 to accurately position the access element for alignment of channel 1202 with other channels.
