Abstract
A disposable cup lid including a cover portion for protecting a drinking surface of the lid from contamination and a base portion for covering a container.
Description
- This application claims the benefit of priority from the following U.S. patent applications: U.S. Patent Application No. 61/124,958, which was filed on Apr. 21, 2008 and entitled “Sanitary Anti-Spill Disposable Cup Lid;” U.S. Patent Application No. 61/125,574, which was filed on Apr. 25, 2008 and entitled “Sanitary Spill Resistant Cup Lid;” and U.S. Patent Application No. 61/125,906, which was filed on Apr. 29, 2008 and entitled “Sanitary Cup Lid.” Each of the foregoing applications is incorporated by reference into the present application in its entirety.
- It is common to dispense hot coffee and tea in a disposable paper or plastic styrofoam cup and to cover the cup with a plastic lid. A primary concern in designing cup lids is to prevent spillage of hot liquids from the cup, to prevent burn injuries. However, when handling disposable cups and lids it is important to keep the lids from becoming contaminated. When a coffee shop employee places a lid on a cup filled with a hot beverage, the cup lid is picked up by hand and placed on the cup. During this procedure, it is inevitable that the hand of the employee touches the cup lid. The area of the cup lid to be contacted with the lip of a coffee drinker can in this way become contaminated with germs transmitted by the hand of the coffee shop employee, which may be a serious public health problem.
- It is desirable for a disposable cup lid to have both sanitary and spill resistant functions. The present cup lids assist in preventing cup lid contamination by hand, avoid the spillage of cup contents, and are easy to manufacture.

base portion 16 includes a generallyhorizontal surface 42 for covering the upper opening of acontainer 12 and avertical wall 44 extending downward (when positioned on thecontainer 12 in normal use) from the periphery of thehorizontal surface 42 to a point below the upper rim of thecontainer 12, in order to contain a liquid or other flowable material within thecontainer 12. Thebase portion 16 also includes alower surface 43 for engaging the rim of acontainer 12 on which thepresent cup lid 14 can be placed. Preferably, thelower surface 43 engages the rim of thecontainer 12 so as to form a friction fit with thecontainer 12, although other means of securing thebase portion 16 to the rim of acontainer 12 known to those of skill in the art can also be employed. The covering apron covers the area of the main cup lid where a user's lip generally touches when drinking a beverage. The two components can be made separately or in a single injection molding process. -
FIG. 1 shows how a disposable cup lid can be contaminated by a hand. When acup 12 filled with a beverage is capped, a disposable cup lid of theprior art 13 is held by ahand 11 and placed on the rim of acup 12. Thedisposable cup lid 13 is then pressed by thehand 13 to fit and seal it to thecup 12. It is inevitable for parts of thehand 13, usually the palm and fingers, to touch the upper surface of thedisposable cup lid 13, and sometimes the area of thedisposable cup lid 13 contacted by thehand 13 during this procedure involves the place where the lips of a user will touch thecup lid 13 when drinking a beverage. This can be a serious public health threat if the hands of the beverage handler harbor dangerous germs. -
FIG. 2 andFIG. 3 illustrate one embodiment of a sanitarydisposable cup lid 14 when it is covered and open, respectively. Thecover portion 15 includes both an anteriormoveable portion 25 and aposterior portion 21, which can be integrally formed, such as through injection molding. The anteriormoveable portion 25 of thecover portion 15 is long and wide enough to cover the area where the lips of a beverage drinker touch when drinking from thelid 14. Preferably, the surface area of the vertically extendingportion 36 of the anteriormoveable portion 25 is between about 3 square centimeters (3 centimeters×1 centimeter), appropriate for a child, and 8 square centimeters (4 centimeters×2 centimeters) for an adult, in order to cover the mouth-touching area of themain cup lid 16. - In order to cover the area of the
main cup lid 16 generally contacted by a user's mouth, the anteriormoveable portion 25 comprises both a horizontally extendingportion 26 and a vertically extendingportion 36. The horizontally extendingportion 26 is secured at aproximal end 27 to theposterior portion 21, and is connected to a proximal end of 37 of the vertically extendingportion 36 at adistal end 28 of the horizontally extendingportion 26. When thecover portion 15 is covering anaperture 19 of themain cup lid 16 through which a user drinks a liquid in thecontainer 12, as shown inFIG. 2 , the horizontally extendingportion 26 is positioned approximately parallel to the horizontal surface 42 (upper surface) of themain cup lid 16 and extends from thehinge 20 to a point at or just beyond the periphery of thehorizontal surface 42. The horizontally extendingportion 26 is sized so as to cover both theaperture 19 as well as a portion of the upper surface of thehorizontal surface 42 around the periphery of theaperture 19. From thisdistal end 28 of the horizontally extendingportion 26, the vertically extendingportion 36 extends approximately parallel to thevertical wall 44 of the main cup lid, i.e. generally downwardly, to a point at or below the lower vertical extent of thevertical wall 44. Thedistal end 38 of the vertically extendingportion 36 can include a projection or handle 22 which extends away from the side wall of thecontainer 12, in order to facilitate moving thecover portion 15 so as to expose theaperture 19, i.e. to open thecover portion 15. - The
aperture cover 17 preferably comprises a downwardly-disposed indentation or stopper in themain cup lid 16 and is sized to fit within theaperture 19. Preferably, thelower surface 35 of theaperture cover 17 contacts all or substantially all of the interior periphery of theaperture 19, and more preferably can form a friction fit with the interior periphery of theaperture 19, in order to close and seal theaperture 19. - The
posterior portion 21 of thecover portion 15 is secured to themain cup lid 16, such as by a friction fit between thelower surface 33 of thecover portion 15 and theupper surface 41 of themain cup lid 16, although these two components can also be physically attached or secured in other manners, such as with an adhesive. Theposterior portion 21 is preferably semi-circular in shape and tightly fits onto the reciprocally shapedportion 23 of themain cup lid 16. In between and connecting the anterior moveable and posterior fixed portions of thecover portion 15 is ahinge 20 that allows the anterior moveable portion to move with respect to theposterior portion 16. - In use, a beverage drinker grasps the
handle 22 of thecover portion 15 using the fingers, and then lifts it to expose theaperture 19 of themain cup lid 16. Thecover portion 15 preferably includes anaperture cover 17 reciprocally molded to fit within theaperture 19. Once thecover portion 15 is lifted up, it can be rotated around the hinge and placed upside down, i.e. with the lower surface facing upward, and can be immobilized by buttoning theaperture cover 17 onto aprotuberance 18 of themain cup lid 16. -
FIG. 4 is a top view of thecup lid 14.FIG. 5 shows the two separate components. Themain cup lid 16 that caps the cup, and thecover portion 15 that in turn covers the main cup lid by fitting its posterior fixed portion onto the reciprocallydepressed portion 23 of the main cup lid. The two components can be manufactured by a single injection molding process, in which the posterior fixed portion of thecover portion 15 and its reciprocallydepressed portion 23 of themain cup lid 16 become one body. -
FIG. 6 illustrates another embodiment of the present sanitary spill-resistant cup lid in a closed position, withFIG. 7 illustrating this cup lid in an open position. As shown inFIGS. 7-9 , in this embodiment the cup lid consists of two parts, a main cup lid (base portion) 120 and amoveable cover 121. Themain cup lid 120 includes acircumferential rim 124, anaperture 132 preferably located on therim 124, aside wall 127 extending downwardly from the outer periphery of therim 124, and aperipheral groove 128 to seal the cup. In addition, themain cup lid 120 has an upwardly projectingcenter post 122 protruding from the center of therim 124. Thecenter post 122 includes an upwardly projecting side wall orwalls 118 and at least abase portion 119 of theside wall 118 that has a cross section which is circular or approximately circular. Acenter post 122 which is not circular in cross section but which allow rotation of themoveable cover 121 can also be use, for example acenter post 122 with a series of flat walls which together approximate a circle in shape. - In between the
center post 122 and therim 124 is anupper surface 115, which in the illustrated embodiment comprises arecess 125 that accommodates adisk 130 of themoveable cover 121. Aventilation hole 123 can be placed in the center top of thepost 122. - The
moveable cover 121 is placed over themain cup lid 120, and has three basic sub-components: thedisk 130, asanitary overlay 133 and theapron 134. The size of thedisk 130 can be large enough to tightly fit therecess 125 of themain cup lid 120 as shown in theFIG. 11 . In this embodiment, therecess 125 of themoveable cover 121 includes upwardly extendingwalls 116 around theperiphery 117 of therecess 125, and at least a portion of theperiphery 138 of the disk engages the upwardly extendingwalls 116 around theperiphery 117 of therecess 125 with a friction fit. Alternatively or in addition, thedisk 130 can have a smaller center hole (central opening) 131 as shown in the embodiment ofFIG. 12 . Thesmaller center hole 131 of the embodiment ofFIG. 12 will tightly fit thecenter post 122 of themain cup lid 120. If thedisk 130 does not tightly fit and remain attached to themain cup lid 120, themoveable cover 121 can be displaced easily from the desirable location that protects the mouth-contacting area. - The
overlay 133 is designed to cover the circular upper surface of therim 124 of themain cup lid 120, and is wide enough to cover the mouth-contacting area. It preferably also has anaperture stopper 132 to fit and seal theaperture 126 in order to make the cup lid spill resistant, in the manner described above for theaperture cover 17. Theoverlay 133 comprises both a horizontally extending portion 141 and a vertically extendingportion 145. The horizontally extending portion 141 is secured at a proximal end to thedisk 130, and is connected to a proximal end of the vertically extendingportion 145 at a distal end of the horizontally extendingportion 131. The vertically extendingportion 145 extends approximately parallel to the vertical wall of the main cup lid, i.e. generally downwardly, preferably to a point at or below the lower vertical extent of the vertical wall. - The
apron 134 comprises a surface attached to the distal end of the vertically extendingportion 145 of theoverlay 133 and extends outwardly (i.e., away from the container when the lid is attached to a container) from theoverlay 133 in order to further cover the mouth contacting area of themain cup lid 120, especially the area likely to contact a user's lower lip. At the distal end of themoveable cover 121 is a serrated edge or handle 136. By rotating theserrated handle 136 around the axis of thecenter post 122 by thumb as shown inFIG. 7 , the cup lid can be opened for drinking. When rotating themoveable cover 121, the position of the thumb does not need to be displaced much by pushing aside theserrated handle 136 repetitively. Once a tooth of theserrated handle 136 is pushed aside, another tooth will be ready to be pushed away as themoveable cover 121 rotates. Therefore, the cup lid can be open by using only one hand. In addition, as shown in theFIGS. 17-19 , by using the thumb only, theapron 134 and theoverlay 133 can be slightly lifted for easy rotation of themoveable cover 121, by extending an upward force against the lower surface or outer edge of theserrated handle 136, and can be pressed to seal theaperture 132. -
FIGS. 10 and 11 are top views of themain cup lid 120 and themoveable cover 121 respectively.FIG. 12 illustrates another embodiment of themoveable cover 121. InFIG. 11 , the diameter of thedisk 130 is large enough to reach and fit therecess 125 of themain cup lid 120. By extending the outer edge of thedisk 125 all the way to the inner side wall 137 (upwardly extending walls 116) of therim 124 of themain cup lid 120, thedisk 130 can be secured and prevented from easy displacement, particularly if theside wall 137 includes an indentation for receiving the outer edge (periphery 117) of thedisk 130. - In
FIG. 12 , the diameter of thedisk 130 is not enough to reach theside wall 137. In this embodiment, however, the side of thecenter hole 131 of thedisk 130 is small enough to tightly fit thepost 122 of themain cup lid 120 to prevent easy displacement. In a similar manner, an indentation can be created on the side wall of thepost 122 to retain the inner edge of thedisk 130 and to thereby further reinforce the secure placement of thedisk 130. When the disk size is small, another indentation on the side wall of thepost 122 can be the only feature to secure thedisk 130 to themain cup lid 120. -
FIGS. 13 and 14 are side views ofFIGS. 8 and 9 respectively.FIG. 15 shows a cross-sectional view of themain cup lid 120 along line B-B ofFIG. 10 . It is a cut view at the exact middle of themain cup lid 120 and illustrates thecenter post 122 with theventilation hole 123, therim 124, therecess 125, theindentation 137, theaperture 126, theside wall 127, theannular groove 129, and theperipheral groove 128. The unique features of thismain cup lid 120 include thecenter post 123 around which themoveable cover 121 rotates to open and close the cup lid, and theindentation 137 which keeps thedisk 130 from lifting. In a similar manner, theindentation 137 can be made in the bottom wall of thecenter post 122 to accommodate the periphery of the central opening of thedisk 130 in order to reinforce the security of thedisk 130. The another indentation can help the smallersized disk 130 ofFIG. 12 from being displaced. Therefore, the spirit of the present invention should not be limited only in this preferred embodiment, but can be applied to other possible embodiments. -
FIG. 16 is the cross-sectional view of themoveable cover 121 at the line C-C ofFIG. 11 when placed on themain cup lid 120. It is colored in black. It illustrates how the components of themoveable cover 121 reciprocally engage to the counterparts of themain cup lid 120. Thedisk 130 is placed on top of therecess 125 with the peripheral edge of the disk extending all the way to theindentation 137. Thecenter hole 131 surrounds and moves around thecenter post 122. Theoverlay 133 protects the mouth touching area of therim 124 of themain cup lid 120. The aperture stopper reciprocally closes theaperture 126 when theoverlay 133 is pressed on therim 124. Thefold 135 between theoverlay 133 and theapron 134 fits into theannular groove 129 of themain cup lid 120 helping to secure themoveable cover 121. The outer edge ofapron 134 can comprise aserrated handle 136 that is pushed aside repetitively by thumb to rotate themoveable cover 121. -
FIG. 20 shows a hand touching the lid of a prior artdisposable cup 232. It is inevitable that an individual attaching such a lid to a cup will touch theaperture 231 and also the area nearby likely to be contacted by the mouth of a user. In another embodiment of the present disposable cup lid, shown inFIGS. 21 , 22, 25 and 26, theaperture 231 and themouth piece 239 are recessed and thus protected from being directly touched by the hand of a user, so that the chance of a hand touching those areas is substantially reduced. Themouth piece 239 is located behind thearms 234 of the cup lid. When the cup lid is picked up, the hands will touch the outer surface of thearms 234 as shown inFIG. 26 . When the cup lid needs to be pressed onto thecup 232 to seal it to thecup 232, the user's palm will touch the horizontalupper surface 233 of the cup lid as shown inFIG. 25 . Therefore, the chance of contamination by hands is minimized. -
FIG. 23 shows an embodiment of the cup lid ofFIGS. 21 , 22, 25 and 26 having elevatedarms 240 guarding theaperture 231 and themouth piece 239. This can further protect themouth piece 239 andaperture 231. By creating ornamental figures on theupper surface 233, as shown inFIG. 24 , drinking coffee or tea can be made more fun, i.e. through the addition of upward ornamental projections 241 (for eyes) and 242 (for a nose) and/or ornamental grooves 243 (FIG. 30 ). The embodiments shown inFIGS. 21-26 , the present lid comprises a horizontalupper surface 233, and an outervertical side wall 235 extending downwardly from an outer periphery 251 of the horizontalupper surface 233. Theside wall 235 has a first vertical side end 260 connected to (preferably directly connected to) a firstvertical end wall 270 and a secondvertical side end 266 connected to (preferably directly connected to) a secondvertical end wall 280. - The first
vertical end wall 270 has aproximal edge 271, adistal edge 272 adjacent the outer periphery of the lid, anupper edge 273, and alower edge 274. The secondvertical end wall 280 likewise aproximal edge 281, adistal edge 282 adjacent the outer periphery of the lid, an upper edge 283, and alower edge 284. Alower wall 290 extends between and connects thelower edge 274 of the firstvertical end wall 270 and thelower edge 284 of the secondvertical end wall 280, thereby forming a recess for protecting the aperture from contamination. When the upper edges of each of the first and second vertical end walls are vertically higher than the horizontalupper surface 233,elevated arms 240 can be formed, as described above. - Horizontally between and/or behind this recess is the
aperture 231, which is positioned below theupper surface 233. Preferably theaperture 231 is located between the firstvertical end wall 270 and the secondvertical end wall 280, i.e. a line extending horizontally from the axial center of the lid radially outwardly that passes through the aperture will be between the firstvertical end wall 270 and the secondvertical end wall 280. Theaperture 231 is also preferably located centrally of the distal edge of at least one of the first and second vertical end walls. Themouth piece 239 comprises anaperture surface 290 where theaperture 231 is located. Themouth piece 239 andaperture surface 290 are preferably positioned vertically higher than thelower wall 290. -
FIGS. 32-36 show another embodiment of the present cup lid which combine the recessed aperture feature of the embodiments ofFIGS. 21-26 and the cover portion of the embodiments ofFIGS. 2-5 . In this embodiment, a cover includes abase portion 247 and anapron portion 245 which protects theaperture 231 and themouth piece 239. The cover can lifted as shown inFIG. 33 , preferably by actuating ahandle 246 to rotate the cover around ahinge 248 attached to the upper surface of the lid. The cover can also be closed to recover the lid.FIG. 33 further illustrates a downwardly-disposed indentation orstopper 244 located on the underside of the cover for sealing liquid in the container, in the manner described previously forindentation 17 inFIGS. 2-5 .FIG. 34 shows the top view of the lid portion only, andFIG. 35 the cover portion only.FIG. 36 illustrates the reciprocal relationship of the cover and the lid. -
FIG. 37 is another embodiment of the present cup lid having agate 250 protecting theaperture 231 and themouth piece 239. Thegate portion 250 can be formed as a thin rectangular band by an injection molding process, after which it would need to be cut horizontally at the lower edge and vertically at the middle so as to allow the gate to open. This process can be done at the time the cup lid is manufactured. Thegate 250 comprises a proximal edge connected to the distal edge of the first and/or the second vertical end wall and a sheet of material extending distally from the proximal edge. - As used herein, the term “comprise” and variations of the term, such as “comprising” and “comprises,” are not intended to exclude other additives, components, integers or steps.
