DETAILED DESCRIPTION OF THE INVENTION
[0023] Some embodiments are described in detail with reference to the related drawings. Additional embodiments, features, and/or advantages will become apparent from the ensuing description or may be learned by practicing the invention. The following description is not to be taken in a limiting sense, but is made merely for the purpose of describing the general principles of the invention. The steps described herein for performing methods form one embodiment of the invention, and, unless otherwise indicated, not all of the steps must necessarily be performed to practice the invention, nor must the steps necessarily be performed in the order listed. It should be noted that references to an or one or some embodiment(s) in this disclosure are not necessarily to the same embodiment, and such references mean at least one.
[0024] The present invention has been conceived with the aim of addressing one or more of the current vacuum mug caps' limitations. More specifically, the present invention is directed to a vacuum mug cap that is spill-proof, double-hinge, and double-function to solve the current limitations.
[0025] Referring to FIG. 1, in this embodiment, a mug 100 is shown fully assembled, closed and sealed. The mug comprises a tumbler 105 and a screw cap 110. The round screw cap 110 comprises a top 120, two pointy oval bumps 130 arising from the top, opposite each other, forming part of the cap's perimeter, that, consequently, create a recess 140 in the middle of the top between the two oval bumps, and shaped like a symmetrical double edged battle axe head, and a lid 150 shaped like a symmetrical single edged battle axe head, disposed snugly in the one half of the recess 140. Obviously, the arch of the lid's 150 edge equals the arches of the recess 140, and, thus, that of the round cap, for the lid 150 to fit snugly in the recess 140. In FIG. 1, the lid 150 is in the first position which is the closed position of the cap. The lid fits snugly in the one half of the recess, and closes a sipper opening. In addition, there are molded easy-grip ribs 160 on the outside walls of the oval bumps, and, thus, of the cap.
[0026] Referring to FIG. 2, an exploded view of an exemplary mug cap and its components, and their relative positions is shown. A mug screw cap 200 comprises a lid 210 that has a shape of a symmetrical single edged battle axe head. The lid 210 further comprises an edge or a blade 211 that is upwardly convex, and, thus, a groove 212 is formed beneath, that snaps fit to a raised rim of the mug cap 200. The lid 210 further comprises a shoulder 213 that has a horizontal tube disposed longitudinally passing through the shoulder 213. The horizontal tube allows a pen 214 of a hole-and-pen hinge pass through. To complete the hinge, about the midway of the pointy oval bumps 230, on the inside walls, there are a pair of recesses 215 to receive the pen 214, and these recesses, the pen, and the horizontal tube form the hinge, upon which the lid 210 can swing from the one half of the recess to the other half. The lid 210 further comprises a bottom 216 that is usually made of silicone or similar elastic materials, and the bottom 216, in turn, comprises a downward protruding tab 217 that plugs a sipper opening 241 on the top of the cap. When assembled, the bottom 216 is attached to the lid 210 by a variety of attachment methods. When the lid 210 is swung to the other side of the recess 240, the protruding tab 217 is pulled from the sipper opening 241, unplugs it, and open it to let the beverage flow through when the mug is tipped.
[0027] Still referring to FIG. 2, in the first open position of the cap, the lid 210 is flipped, from the closed position, to the other half of the recess 240 and fits snugly. A second lid 220 previously hidden under the first lid 210 is exposed. The second lid 220 is round and attached or molded to the bottoms of the inner halves of the oval bumps 230, which, in this embodiment, are split along the major axes. In the center of the second lid 220, a hole 221 is made, and, perhaps, countersink. The hole 221 receives a screw 220 that attaches a bottom 223 to the bottom of the lid 220. It is appreciated that a variety of attachment methods can be used to attach the bottom 223. The bottom 223 is usually made of silicone or similar elastic materials. The bottom 223 perimeter snugly fits a second opening 242 on the top of the cap. In the closed position, the second lid 220 and its attached bottom 223 press against the second opening 242 lip tight and seals any gaps between the silicone bottom 223 and the second opening 242.
[0028] In the second open position of the cap, the second lid 220 is yanked open by a user pulling the first lid 210 functioning as a pull tab. This motion can be done because the first lid 210, or the pull tab, is attached by the hinge to the inner halves of the oval bumps 230, which, in turn, are attached to the second lid 220, as disclosed above. The second lid 220 and the inner halves of the oval bumps 230 form a flapper lid with the two inner halves being the two arms. The two halves of the oval bump 230 then scissor away from each other on a pivot pin 231 disposed at the one end of the major axis. The second opening 242 can accommodate a removable infuser.
[0029] Still referring to FIG. 2, a cylindrical section 243 of the mug cap under the top thereof is male threaded to mate with the female threads on the inner wall of the neck of the tumbler 105. In this embodiment, a perforated, cylindrical infuser/strainer 250 is used. The neck 251 of the cylindrical strainer 250, near the lip, is male threaded to mate with the female threaded inner wall of the second opening 242. The strainer 250 has a detachable bottom 260, that is also perforated. The strainer bottom 260 use a screw cap attachment to attach to the bottom opening of the strainer 250. It is appreciated that other embodiments can have fused bottom, or attached bottom with a variety of attachment methods.
[0030] Referring to FIG. 3, an assembled exemplary mug cap and strainer/infuser 300 is shown. FIG. 3 shows the first lid 310 is used as a pull tab to pull open the second lid 320. The inner halves of the oval bumps 330 scissor away from the outer halves on the pivot pin 331. As the second lid 320 is pulled open, the second opening 340 is exposed. When the second opening is open, a user can insert a removable infuser filled with coffee grinds or tea leaves, and fill the mug with hot water to start brewing. The perforated strainer 350 can accommodate a removable infuser, a commercial tea bag, or a variety of other brew materials. Moreover, where a POD brewing machine is available, the second opening, and easily opened second lid, let the user greatly enjoy the innovative and convenient brew-through capability of the current invention's mug cap. With just a gently pull of the first lid acting as a pull tab, the second lid is opened and ready to get a fill or refill from the POD brewer. Then, the user closes the second opening 340 by pressing the second lid 320 down tight to prevent spilling. The user can choose to plug the sipper opening by closing the first lid 310. This is recommended when she is about to travel. After certain brewing time, the user can open the first lid 310 to sip and enjoy the brew. If the user wants to remove the removable infuser after a preferred brewing time, she can gently yank the second lid 320 open, using the first lid 310 as a pull tab. The combination of the double hinges (a hole-and-pen and a pivot-pin), double lids, and the first lid functioning as a pull tab solves the limitations of the current mug caps, where a user desires to safely and conveniently remove brew waste after a preferred brewing time.
[0031] Referring to FIG. 4, a cross-sectional view of an exemplary mug 400 and its cap is shown. The first lid's edge or blade 410 is upwardly convex, and a groove is formed beneath. The outer wall of the groove includes a resilient annular gripping portion that engages the raised rim 420 of the cap. The raised rim 420 comprises a bead running along the rim, on the outer wall. When the lid is pressed down, the resilient annular gripping portion expands outward until it grips the underside of the bead. The lid's bottom has a protruding tab 430 that, when the lid is pressed down, plugs the sipper opening 440, and prevents spillage. A strainer/infuser 450 is screwed in the second opening of the cap from the underside thereof. The infuser is covered with perforations for brewing in this embodiment. It is appreciated that many other types of infusers, e.g., wire mesh basket or metal cage basket, can be used. It is appreciated that tea bags can be dropped in the infuser, and safely and conveniently removed. It is also appreciated that a user can open both lids, using the first lid as a pull tab, and let the brew come down from the dispenser of a POD machine. Filling or refilling this way saves the user valuable time day after day, and provide convenience and enjoyment of using the current invention's mug caps.
