DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0057]
[0058] Straw 18 is insertable into the container 10 such that a portion of the straw protrudes through the straw aperture 16. In the preferred embodiment, the straw aperture 16 is located in the centre of the lid, however the aperture may also be offset from the centre such as is shown for example in
[0059] Straw 18 is a tube with a bottom end and a top end. The bottom end of straw 18 comprises at least two protrusions 20, 22 presenting surfaces for mixing the contents of the container. Preferably, the protrusions extend from opposite sides of the bottom of the straw. The shape of the protrusions may vary and may include, for example, co-planar tabs, angled fins, tabs or fins with or without taper, and with or without apertures, among other possible shapes and arrangements.
[0060] As the straw is intended to be rotated by a magnetic stirrer, the shape and location of the protrusions in relation to the base of the straw should be configured to allow the straw to rotate on the bottom of the beverage container. In the event that the lowermost portion of the straw consists of the bottoms of the protrusions themselves, such bottoms are preferably shaped so as to minimize the friction with the bottom of the container. Where the protrusions are spaced from the base of the straw tube, the base will typically provide sufficiently low friction to enable the straw to be rotated about the bottom of the container.
[0061] The protrusions 20, 22 comprise a ferromagnetic material capable of coupling to a magnetic field. In the preferred embodiment, protrusions 20, 22 extend about the base of the straw 18 in opposite directions perpendicular to the length of the straw 18. If the protrusions are themselves magnetic so as to have magnetic polarities, the extremities of the two protrusions preferably have opposed magnetic polarities.
[0062] Mixing straw 18 may also comprise, in addition to protrusions 20, 22, additional fins, tabs or vanes to assist with the mixing of the beverage as the straw rotates. It will be appreciated that such additional protrusions may be placed anywhere along the length of the straw.
[0063] Magnetic stirrer 44 includes a rotating magnetic assembly 46 whose ends 48, 50 have opposed magnetic polarities. As the rotating magnetic assembly 46 spins within the magnetic stirrer 44, it creates a rotating magnetic field above the magnetic stirrer 44 such that when the container 10 is placed over the magnetic stirrer 44, the ferromagnetic protrusions 20, 22 on the base of the mixing straw 18 magnetically couple with the rotating magnetic field and cause the mixing straw 18 to spin and to thereby mix the beverage in the container. Once the beverage is mixed, it may be sipped directly through the mixing straw 18.
[0064] It will be appreciated that other straws and magnetic stirrers with greater or fewer protrusions on the straw and different magnetic orientations may be used, provided that the protrusions are capable of magnetically coupling with the rotating magnetic field generated by the magnetic stirrer.
[0065] Using the invention, the straw 18 is placed into the beverage container and the lid 12 is placed over the beverage container such that a top portion of straw 18 passes through aperture 16 in the lid 12. One or more beverage ingredients are added into the beverage container 10 through an opening in the lid 12 created by foldable tab 17. The beverage container is placed over the magnetic stirrer 44 and the magnetic stirrer 44 is powered to create a rotating magnetic field that causes the mixing straw 18 to spin or rotate and to thereby mix the beverage.
[0066] It will be appreciated that beverage ingredients may be added directly into the beverage container 10 before the lid 12 is placed on top of the beverage container 10. Additionally, the beverage container 10 may be placed on the magnetic stirrer 44 prior to adding the beverage ingredients. The magnetic stirrer 44 may also be powered while the beverage ingredients are being added into the beverage container 10.
[0067]
[0068] The magnetic stirrer 80 comprises a rotating magnetic assembly 84 with two magnets 86, 88 extending upwards into the projection 82 to maximize the proximity of the magnetic field to the protrusions 62, 64. The magnetic assembly 84 spins to create a rotating magnetic field through the projection 82 of the magnetic stirrer 80 and through the stub 76 of the beverage container 70. The rotating magnetic field generated by magnets 86, 88 in the magnetic stirrer 80 couple with the two ferromagnetic protrusions 62, 64 at the base of the mixing straw 60 causing the mixing straw 60 to spin and mix the contents of beverage container 70. Recess 66 and stub 76 allow the base of the straw 60 to remain centered as it spins and enables better magnetic coupling between the ferromagnetic protrusions 62, 64 and the magnetic field generated by the rotating magnets 86, 88 in the magnetic stirrer 80.
[0069] A user places the straw 60 into the beverage container and the lid 72 over the beverage container such that a top portion of straw 60 passes through a straw-retaining aperture 74 in the lid 72. In installing the straw 60 into the container 70, the recess 66 between protrusions 62, 64 of the mixing straw 70 is placed over the stub 76 at the bottom 78 of the container 70. One or more beverage ingredients are added into the beverage container 70 through an opening in the lid 72 created by foldable tab 75. The beverage container is positioned over the magnetic stirrer 80 such that the projection 82 fits within the stub 76. The magnetic stirrer 80 is then powered to create a rotating magnetic field that causes the mixing straw 70 to spin or rotate and to thereby mix the beverage.
[0070] It will be appreciated that beverage ingredients may be added directly into the beverage container 70 before the lid 72 is placed on top of the beverage container 70. Additionally, the beverage container 70 may be placed on the magnetic stirrer 80 prior to adding the beverage ingredients. The magnetic stirrer 80 may also be powered while the beverage ingredients are being added into the beverage container 70.
[0071]
[0072] In use, the straw 94 is placed into the beverage container and the lid 92 is placed over the beverage container such that a top portion of straw 94 passes through a straw-retaining aperture in the lid 92. One or more beverage ingredients are added into the beverage container 90 through an opening in the lid 92 created by foldable tab 93. The magnetic stirrer 96 integrated into the base of the beverage container 90 is powered to create a rotating magnetic field that causes the mixing straw 94 to spin or rotate and to thereby mix the beverage.
[0073] It will be appreciated that beverage ingredients may be added directly into the beverage container 90 before the lid 92 is placed on top of the beverage container 90. The magnetic stirrer 96 may be powered while the beverage ingredients are being added into the beverage container 90.
[0074]
[0075] It is contemplated that magnetic stirrers for mixing beverages may be integrated into a beverage dispensing machine.
[0076] Preferably, a lid 120 has a foldable tab 122 that may be folded over to create an opening in the lid 120 that allows the beverage dispenser to dispense beverage ingredients through the opening and into the beverage container 116 while the lid 120 is on the beverage container 116. It will be appreciated that various alternate means of creating an opening in the lid are possible including sliding means. For example, a lid may have an opening and a sliding panel wherein the panel can slide between a first position that covers the opening and a second position that uncovers the opening.
[0077] In some cases, as is shown in
[0078] To prepare a beverage using the beverage dispenser embodiment of the invention, a beverage container 116 with a lid 120 and magnetically actuated mixing straw 118 is placed on the platform 114 of the beverage dispenser 110. Foldable tab 122 is folded over to create an opening the in lid 120 and one or more beverage ingredients are dispensed into the beverage container 116 through the opening while the beverage container 116 rests on the platform 114. The magnetic stirrer housed under the platform 114 is powered to create a rotating magnetic field that causes the mixing straw 118 to spin or rotate and to thereby mix the beverage. The magnetic stirrer may be powered to mix the beverage while the ingredients are being dispensed or shortly after the beverage ingredients have been dispensed. Once the beverage is mixed, the container 116 can be lifted off the platform 114 and a user can immediately drink the beverage through straw 118.
[0079] In the above described embodiments, the straw aperture in the lid restricts the lateral movement of the portion of the mixing straw that passes through it while the straw rotates. Without the straw aperture and lid, the top of the mixing straw would move chaotically about the top of the beverage container as the ferromagnetic protrusions on the base of the mixing straw spin. Such chaotic movement may cause undesirable splashing or spilling of the beverage. The use of the lid with a straw aperture serves to hold the mixing straw in place during mixing.
[0080] In an alternate embodiment of the invention shown in
[0081] Referring to
[0082] In operation, the arms 138 of the guide 130 act to maintain the vertical alignment of the mixing straw 132 as the mixing straw 132 rotates. A gap between the bore 136 of the guide 130 and the mixing straw 132 allows the mixing straw 132 to rotate within the guide 130. The guide may remain stationary during mixing or may rotate during mixing due to friction between the rotating mixing straw 132 and the interior bore surface of the guide 130.
[0083] In alternate embodiments, the top of the mixing straw may be above the beverage container (as shown in
[0084] The configuration of the guide 130 may also vary. For example, rather than two arms extending outwards from the body, the guide may contain just one arm. Alternative the guide may have more than two arms. It is also contemplated that the guide's arms may extend outwards from the body of the guide at an angle to the bore rather than perpendicularly to the axis of the bore. If the guide contains just one arm, the end of the arm is preferably secured to the inner surface of the beverage container.
[0085] It will be appreciated that there are various other ways to prevent the guide from sliding down the mixing straw and contacting the protrusions. For example and referring to
[0086] The connection between the guide and the mixing straw may be such that the guide rotates with the mixing straw if the arms are not fixed to the inner surface of the beverage container.
[0087]
[0088] The lid 152 may contain a straw holder 156 for retaining the second straw piece 150 when it is not in use. The lid 152 may also contain a cap or stopper for the aperture 154 to prevent the contents in the beverage container 142 from coming out through the aperture 154.
[0089] The second straw piece 150 and the top portion 144 of the mixing straw 132 may be magnetized to assist with their connection. Alternatively, the second straw piece 150 may be sized to fit snugly inside or outside the top portion 144 of the mixing straw 132.
[0090] The magnetic stirrer 160 shown in
[0091] In an alternate embodiment, a drinking straw may be detachable from a magnetic stirring implement. As shown in
[0092] The stirring implement has an drinking aperture 224 located substantially at its centre. The drinking aperture 224 allows liquid to pass through the stirring implement 220 from one side of the stirring implement to the opposite side of the stirring implement. Referring to
[0093] It can be difficult to quickly align a drinking straw 228 with the drinking aperture 224 of the stirring implement 220 when the stirring implement 220 is located at the base of a container 230. A user must carefully try to guide the straw 228 towards the drinking aperture 224. For opaque beverages such as milkshakes or for beverage containers with non-translucent walls, alignment is particularly difficult as a user cannot visually guide the straw 228 to connect with the stirring implement 220 located at the bottom of the container.
[0094] To assist in the alignment of the straw 228 with the stirring implement 220, the stirring implement 220 preferably has a guide 232 to direct the drinking straw 228 towards the drinking aperture 224. The guide 232 is located on one side of the stirring implement and is aligned with the drinking aperture 224.
[0095] As shown in
[0096] A similar guide may also be located on a beverage container lid to align a straw with an aperture located on the lid. The guide on the lid enables a user to easily place a lid over a straw such that the straw is aligned with an aperture on the lid.
[0097] In one embodiment, the guide 246 on the lid 240 is funnel-shaped and located on the second side 244 of the lid. The funnel-shaped guide is narrowest in circumference at or near the location that it is closest to the aperture 248 of the lid 240 and is widest in circumference at or near the location that is furthest from the aperture 248 of the lid 240.
[0098] Referring now to
[0099] It will be appreciated that the lid 240 with the guide 246 may be used with a standard tubular drinking straw. Alternatively, the lid 240 may be used with any of the straws described above and shown in
[0100] The preparation and mixing of a beverage may be controlled by logic stored in the magnetic stirrer used to mix the beverage or logic stored in the beverage dispenser. Such logic may be contained in software stored on a microcontroller is located within the magnetic stirrer or the beverage dispenser. The magnetic stirrer may communicate with a beverage dispenser and use the logic to control the sequence and quantity of beverage ingredients added into a beverage container, the mixing speed of the magnetic stirrer, and the mixing duration of the magnetic stirrer.
[0101] In the foregoing specification, the invention has been described with reference to specific embodiments thereof. However, the scope of the invention should not be limited by the preferred embodiments set forth in the examples, but should be given the broadest interpretation consistent with the description as a whole. The specification and drawings are, accordingly, to be regarded in an illustrative rather than a restrictive sense.
