DETAILED DESCRIPTION OF THE INVENTION
(18) The present invention relates to lid for a cup which protects the drinking hole from germs or other contaminates.
(19) This description uses the terms molded and punched interchangeably, both referring to the general process of manufacturing the various parts of lid 1. These terms are not intended to be limiting as to the type of manufacturing method or style.
(20) As seen in
(21) In many embodiments cover 2 is provided with gripping projection 14 to aid the user in rotating cover 2. In come embodiments gripping projection 14 is provided on the side of cover 2, an example of which can be seen in
(22) In other embodiments cover 2 is provided with at least two fastening projections 15 on the inside of cover 2. In some embodiments when cover 2 rotates to the open position, locking projection 16 on base 3 fits between fastening projections 15, which locks cover 2 in an opened position. Locking in an open position is important as it allows the user to tip and drink out of cup 25 without having to hold cover 2 open. If this was not the case cover 2 could slide back into a closed position and interrupt their drink or splash liquid onto the user. In some embodiments locking projection 16 is generally opposite of drinking hole 4 and fastening projections 15 generally centered on cover 2, such that cover 2 is locked in the fully open position. In other embodiments either locking projection 16 or fastening projections 15 are in different positions such that cover 2 is locked in an open position but not the fully opened position. Locking cover 2 in the fully open position moves cover 2 as far away from drinking hole 4, and is the most aesthetically pleasing, while locking cover 2 in another open position allows cover 2 to stay open without having to twist it fully to the other side of base 3. In some embodiments there are multiple locking projections 16 such that cover 2 can be locked in an open position which is either to the left or right of drinking hole 4, which gives the user the option of which direction they open cover 2. This option is useful as depending on which hand the user is holding their cup in, cover 2 may be more easily pushed in one direction versus the other. In other embodiments there is a locking projection 16 located near drinking hole 4 which locks cover 2 in the closed position, but in many embodiments cover 2 is locked in the closed position by stopper 13 being removably attached within drinking hole 4. In other embodiments locking projection 16 fits into the backside of gripping projection 14, which locks cover 2 in an open or closed position.
(23) In other embodiments locking ridge 17 is provided on base 3 which fastening projection 15 fits into as a means of locking cover 2 in an open or closed position. These embodiments beneficially allow cover 2 to be only equipped with one projection 15. In some embodiments locking ridge 17 is provided along with locking projection 16, and in other embodiments only locking ridge 17 or locking projection 16 is provided. In some embodiments multiple locking ridges 17 are provided.
(24) As discussed above, in many embodiments stopper 13 is removably attachable inside of drinking hole 4 which locks cover 2 in a closed position. In many embodiments stopper 13 projects down from the top surface of cover 2. Having stopper 13 act as the locking mechanism beneficially keeps cover 2 closed and avoids the possibility that cover 2 shifts open during travel, exposing drinking hole 4 to the air. Additionally, using stopper 13 as the projection which is removably attachable into drinking hole 4 avoids having to add additional locking features to either cover 2 or base 3, thus reducing the complexity of manufacturing. In other embodiments, stopper divot 36 is provided on base 3 where stopper 13 is removably attachable into in order to lock cover 2 in an open position. As with drinking hole 4, these embodiments beneficially avoid having to add additional features to either cover 2 or base 3, thus reducing complexity of manufacturing.
(25)
(26)
(27) Similar to the embodiment shown in
(28) Also shown in
(29) Having halting material section 21, lower halting projection 23, or tab 26 is useful to the embodiments shown in
(30) In many embodiments, the outer perimeter of stopper 13 is chamfered, being slightly smaller at the bottom then at the top. The benefit of the chamfered perimeter is that it causes stopper 13 to fit more tightly within drinking hole 4. In other embodiments, stopper 13 is equipped with lower halting projection 23, which helps secure stopper 13 within drinking hole 4, as discussed above.
(31) In some embodiments, as seen in
(32) In some embodiments, both ramp 20 and stopper 13 are provided on lid 1, in other embodiments only ramp 20 is provided, and in other embodiments only stopper 13 is provided.
(33) As shown in
(34)
(35) In some embodiments, splash guard stopper 30 is a projection punched in from outer perimeter 29 towards inner perimeter 28. These embodiments are useful because the cavity in outer perimeter 29 caused by splash guard stopper 30 can be used to capture fastening projection 15 and lock cover 2 in the closed position, limiting the need to add additional locking features to either cover 2 or base 3, thus reducing complexity of manufacturing. In some embodiments splash guard 27 is a projection extending from outer perimeter 29 towards inner perimeter 28. In some embodiments, splash guard 27 extends across and is connected to both inner perimeter 28 and outer perimeter 29.
(36) In other embodiments, such as the one shown in
(37) As mentioned above, splash guard 27 beneficially limits liquid from splashing up and out of drinking hole 4 when not desired. When the user wants to drink however, the liquid inside of cup 25 can flow around the sides of splash guard 27 and up towards drinking hole 4.
(38) In some embodiments, base 3 is equipped with heat indicator 35, which tells the user the approximate temperature of the liquid inside of cup 25. In some embodiments only one heat indicator 35 is provided. In some of these embodiments, heat indicator 35 tells the user when the liquid inside of cup 25 is unsafe to drink, such as temperatures over 160° F. In other embodiments there are multiple heat indicators 35. In some of these embodiments, each heat indicator 35 has a different temperature window, which tells the user the approximate internal temperature so that the user can drink their beverage at the desired temperature. For example, a first heat indicator 35 could tell the user when the beverage is over 160° F., and thus unsafe to drink, a second heat indicator could tell the user when the beverage is over 120° F., and a third could tell the user when the beverage is over 80° F. Thus, some users may want to drink their beverage at about 140° F., so they would consume their beverage when the first indicator is “off” and the second and third indicators are “on” which means that the beverage is below 160° F. and above 120° F. Other users may want to drink their beverage at 100° F., thus they would consume their beverage when both the first and second indicators are “off” and only the third is “on.” When all three indicators are “off” this can indicate that the beverage needs to be discarded or re-heated in order to bring the beverage back up to the desired temperature. In some embodiments the temperature range is punched into lid 1 which beneficially tells the user what is the range of heat indicator 35. In some embodiments this temperature punch is heat indicator 35 and in other embodiments it is supplied along with heat indicator 35.
(39) In some embodiments, heat indicator 35 is a punched area painted with thermochromic paint. In some embodiments with multiple heat indicators 30, each indicator has different colored thermochromic paint to denote the different temperature, and in other embodiments all of the thermochromic paints are the same color, and the different temperature ranges are denoted by another method, such as by a label or punched letters. In some embodiments, heat indicator 35 is punched towards the inside of cup 25 and in other embodiments heat indicator 35 is punched outwards.
(40) In some embodiments with heat indicator 35, heat well 31 is provided which aids in the trapping of the heat released from the liquid in order to make heat indicator 35 more effective, as seen in
(41) As seen in
(42) In some embodiments, lid 1 is further equipped with a protective layer 33 which is removed before use. In some embodiments protective layer 33 is permanently removed and in other embodiments protective layer 33 is temporarily removed when the user is drinking, and replaced when the cup is not in use. In some embodiments, such as the one shown in
(43) In some embodiments, protective layer 33 only covers a portion of lid 1, generally around drinking hole 4, in other embodiments protective layer 33 covers both drinking hole 4 and vent 32, and in other embodiments protective layer 33 covers the entire lid 1. In some embodiments, protective layer 33 is made of the same material as lid 1 and in other embodiments protective layer 33 is made of a different material as lid 1.
(44) In many embodiments lid 1 is made of generally heat resistant material such as heat resistant plastics, silicon, metal, or wood. In many embodiments the material is also resistant to rusting. In some embodiments lid 1 is generally made of all the same material and in other embodiments lid 1 is generally made of different materials. Embodiments where lid 1 is made of all the same material are useful for ease of manufacturing, while embodiments where lid 1 is made of different materials is useful as different areas of lid 1 may function better with different materials. For example, in some embodiments heat well 31 is made of metal in order to better conduct the heat while the rest of lid 1 is made of silicon in order to be flexible and reduce costs.
(45) In some embodiments, base 3 is all one layer and in other embodiments base 3 is more than one layer. In some embodiments with multiple layers each layer is made of generally the same material and in other embodiments with multiple layers at least some of the layers are made of different materials. Embodiments with multiple layers with different materials are useful as this allows lid 1 to be provided with insulation which keeps the contents of cup 25 at the desired temperature longer. Embodiments with a single layer are useful as this decreases manufacturing complexity and allows the lid to be more easily recycled if made from recyclable material.
(46) In some embodiments, lid 1 is removable from cup 25 and in other embodiments lid 1 is integrally connected to cup 25.
(47) While the present invention has been particularly described, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art in light of the foregoing description. For example, while hole 4 has been described as a drinking hole, lid 1 can be used for purposes other than drinking, such as pouring liquids or other materials out of hole 4. Thus, lid 1 is not limited strictly to drinking purposes. These descriptions and drawings are exemplary of specific embodiments only and are not intended to be limiting to the scope of the invention defined in the claims. It is therefore contemplated that the claims will embrace any such alternatives, modifications, and variations as falling within the true scope and spirit of the present invention.
