[0002] A cup is a container for drinking various beverages. For a long time, the function of a cup is only to hold drinking liquids. It has no other special functions and does not change or enhance the flavor of the beverage. Summary of the invention

[0004] The inventor believes that if the flavor of a drink can be changed through a cup, the fun and experience of drinking the drink can be greatly enhanced. One purpose of the present invention is to provide a cup that has the function of changing the flavor of a drink.

[0005] Another object of the present invention is to provide a cup that allows a drinker to feel and taste different flavors of a drink when drinking from different positions of the cup.

[0006] Another object of the present invention is to provide a cup that can experience different flavors, and the cup can be used to drink beverages from 360 degrees, and different degrees of tasting flavors can be tasted.

[0007] An embodiment of the present invention provides a cup, the cup having a cup body and a cup mouth, the cup mouth having a cup rim; wherein: The cup mouth has a front side, a rear side, and a left area and a right area located between the front side and the rear side; The cup mouth is an outward-turned cup edge at least at the front side and the rear side, and the outward-turned angle of the cup edge at the front side is greater than the outward-turned angle of the cup edge at the rear side.

[0008] Thereby, the cup provides two eversion angles at the front and rear sides of the cup edge. When drinking a beverage from the front or rear side of the cup edge, the beverage can enter different positions of the mouth and tongue at different angles. The taste buds at different positions can feel the different flavors of the beverage, so that the cup provides the function of changing the taste of the beverage.

[0009] Preferably, the cup edge of the left area is also at an outward angle, and the outward angle of the cup edge of the left area is a gradual change, and the outward angle gradually decreases from the front side of the cup mouth to the back side; the cup edge of the right area is also at an outward angle, and the outward angle gradually decreases from the front side of the cup mouth to the back side. In this way, when drinking the beverage from the cup at a 360-degree angle of the cup edge, the beverage enters different positions of the mouth and tongue, presenting a variety of rich tastes and flavors.

[0010] Another embodiment of the present invention provides a cup capable of experiencing different flavors of beverages, the cup comprising a cup body and a cup mouth, the cup mouth having a cup rim; wherein: The cup mouth has a front side, a rear side, a left area and a right area, wherein the left area and the right area are respectively located between the front side and the rear side; The rim of the cup mouth is an outward-turned rim at least on the front side, the left area and the right area, the rim of the front side has a front outward-turned angle; the rim of the left area has at least one left area outward-turned angle; the rim of the right area has at least one right area outward-turned angle; the front side outward-turned angle, the at least one left area outward-turned angle and the at least one right area outward-turned angle form at least two different angles.

In this way, the cup edge of the cup provides at least two different entrance angles, so that the mouth and tongue can feel different flavors and tastes of the beverage. Preferably, the cup edge on the front side of the cup mouth has the longest outward extension length. When the cup is placed at the front side of the cup edge, the beverage in the cup can flow into the depth of the mouth and the root of the tongue.

[0017] Preferably, the cup edge at the rear side of the cup mouth has the shortest outward extension length to facilitate the beverage to flow into the oral cavity (front end of the oral cavity) and the tip of the tongue.

[0018] Preferably, the peripheral wall of the cup body is formed by a plurality of spiral sheets arranged in a ring shape, thereby promoting the flow of the beverage in the cup and making the beverage collide with each other during drinking, making the beverage uniform and providing the flavor of the beverage.

[0029] See also Figures 1 to 4 , showing a cup 10 capable of presenting different flavors provided by the first preferred embodiment of the present invention. When drinking beverages from different positions using the cup of the present invention, the drinker can experience different flavors.

[0030] The cup 10 comprises a cup body 15, a cup mouth 20 and a cup bottom 18. The cup mouth 20 comprises a cup rim 30, which is the periphery of the cup mouth. In the preferred embodiment, the cup body 15 is annular, and its periphery is formed by a plurality of spiral sheets 16 arranged in an annular manner, and a spiral intersection line 161 is formed between two adjacent sheets 16.

[0031] The cup 10 has a longitudinal direction L, which is the vertical direction from the cup mouth 20 to the cup bottom 18; the inclination angle of each body 16 is α, and the inclination angle α can be the angle between the intersection line 161 and the longitudinal direction L of the cup 10. Preferably, the inclination angle α is between 20 degrees and 60 degrees, preferably between 30 degrees and 50 degrees.

[0032] See also Figure 2 , the cup mouth 20 can be distinguished into different positions, including a front side 21, a rear side 22, and a left area A and a right area B located between the front and rear sides. For example, the cup mouth 20 is divided into eight equal parts, so that the cup mouth has different positions such as the front side 21, the rear side 22, the left side 23, the right side 24, the left front side 25, the left rear side 26, the right front side 27 and the right rear side 28. The left area A refers to the range of the left side of the cup mouth 20 between the front side 21 and the rear side 22, including the left side 23, the left front side 25, the left rear side 26 and other positions; the right area B includes the range of the right side of the cup mouth between the front side 21 and the rear side, including the right side 24, the right front side 27, the right rear side 28 and other positions. The aforementioned eight equal parts are only an example, and can be divided into other proportions according to actual needs, such as three equal parts, four equal parts, five equal parts, six equal parts, ten equal parts, twelve equal parts, sixteen equal parts, etc.

[0033] See also Figures 5 to 8 The cup rim 30 of the cup mouth 20 can be defined as a cup rim 31 at the front side 21, a cup rim 32 at the rear side 22, a cup rim of the left area A and a cup rim of the right area B. The cup rim of the left area A includes a cup rim 33 at the left side 23, a cup rim 35 at the left front side 25, and a cup rim 36 at the left rear side 26; the cup rim of the right area B includes a cup rim 34 at the right side 24, a cup rim 37 at the right front side 27, and a cup rim 38 at the right rear side 28.

[0034] In a preferred embodiment of the present invention, the rim 30 of the cup mouth 20 is made into an outward-turned rim, that is, the rim 30 extends outward instead of inward, and the rims at different positions have different outward-turned angles.

[0035] Figure 5 The cup edges 31, 32 at the front side 21 and the back side 22 of the cup mouth 20 of the cup 10 and the eversion angles θ1, θ2 of the two cup edges 31, 32 are shown. Each cup edge 31-38 extending outward is an inclined surface or a curved surface. With the longitudinal direction L as a reference, the eversion angle described in this specification is the angle between the surface (inclined surface or curved surface) of each cup edge and the longitudinal direction L of the cup 10, especially the angle between the end edge of the cup edge and the longitudinal direction L.

[0036] In this embodiment, the eversion angle of the cup edge 31 at the front side 21 (hereinafter referred to as the front eversion angle) θ1 is greater than the eversion angle of the cup edge 32 at the rear side 22 (hereinafter referred to as the rear eversion angle) θ2. The cup edge of the left area A of the cup mouth 20 has at least one or more left area eversion angles, see Figures 6 to 8 The left region eversion angle may be formed by any one or all of the eversion angle θ5 of the cup edge 35 at the left front side 25, the eversion angle θ3 of the cup edge 33 at the left side 23, and the eversion angle θ6 of the cup edge 36 at the left rear side 26. When the cup edges at several positions in the left region each have an eversion angle, the plurality of eversion angles may be independent and preferably have different angle values, and the change of the angle does not necessarily need to be continuously increased or decreased. The angle value of the at least one right region eversion angle is preferably different from the angle value of the front side eversion angle θ1 or the rear side eversion angle θ2, so that the cup edges at different positions of the cup 10 have two or more eversion angles.

[0037] The outward turning angle of the cup edge of the left area A of this embodiment gradually and continuously decreases from the front side 21 to the rear side 22. Please refer to Figures 6 to 8 The eversion angle θ5 of the cup edge 35 at the left front side 25 (hereinafter referred to as the left front eversion angle) is smaller than the front eversion angle θ1 of the front side 21, but larger than the eversion angle θ3 of the cup edge 33 at the left side 23 (hereinafter referred to as the left eversion angle); and the eversion angle θ6 of the cup edge 36 at the left rear side 26 (hereinafter referred to as the left rear eversion angle) is smaller than the left eversion angle θ3 of the cup edge 33 at the left side 23, but larger than the rear eversion angle θ2 of the cup edge 32 at the rear side 22.

[0038] Similarly, the rim of the right side region B of the cup mouth 20 has at least one or more right side region eversion angles, which can be formed by including but not limited to the eversion angle θ7 of the rim 37 at the right front side 27, the eversion angle θ4 of the rim 34 at the right side 24, and the eversion angle θ8 of the rim 38 at the right rear side 28. When the rims at several positions of the right side region all have an eversion angle, the plurality of eversion angles can be independent and preferably have different angle values, and the change of the angle does not necessarily need to be continuously increased or decreased. It is preferred that the angle value of the at least one right side region eversion angle is different from the angle value of the front side eversion angle θ1 or the rear side eversion angle θ2, so that the rims at different positions of the cup have two or more eversion angles.

[0039] In this embodiment, the eversion angle of the cup rim in the right area B gradually and continuously decreases from the front side 21 to the rear side 22. The eversion angle θ7 of the cup rim 37 at the right front side 27 (hereinafter referred to as the right front eversion angle) is smaller than the front eversion angle θ1 of the front side 21, but larger than the eversion angle θ4 of the cup rim 34 at the right side 24; and the eversion angle θ8 of the cup rim 38 at the right rear side 28 (hereinafter referred to as the right rear eversion angle) is smaller than the right eversion angle θ4 of the cup rim 34 at the right side 24, but larger than the rear eversion angle θ2 of the cup rim 32 at the rear side 22.

[0040] Therefore, among the cup rims 31-38 of the cup 10, the front side eversion angle θ1 is the largest eversion angle, the rear side eversion angle θ2 is the smallest eversion angle, the eversion angles θ5, θ3, θ6 of the cup rims 25, 23, 26 of the left area A decrease from the front side 21 to the rear side 22 of the cup 10, and the eversion angles θ7, θ4, θ8 of the cup rims 27, 24, 28 of the right area B also decrease from front to back, and the cup rims 31-38 at different positions present different eversion angles.

[0041] In addition, in this preferred embodiment, the length of the cup edge 30 extending outward at each location of the cup mouth 20 is also different, wherein Figure 2 and Figures 5 to 8 As shown, with the center P of the cup body as a reference, the cup rim 31 of the front side 21 has the longest outward extension length S1, while the cup rim 32 of the rear side 22 has the shortest outward extension length S2. The outward extension lengths of the cup rims 25, 23, 26 of the left region A also decrease continuously from the front side 21 to the rear side 22 of the cup 10, that is, the outward extension length S4 of the left front side cup rim 25 is greater than the outward extension length S3 of the left side cup rim 23, and the outward extension length S3 of the left side cup rim 23 is greater than the outward extension length S5 of the left rear side cup rim 26. Similarly, the outward extension lengths of the cup rims 27, 24, 28 of the right region B also decrease from the front side 21 to the rear side 22, and the outward extension lengths of the cup rims 27, 24, 28 are not the same. When a cold drink or a hot drink flows into the mouth from cup rims of different extension lengths, the contact time between the drink and the air will be different. For example, when the drink flows into the mouth from the front cup rim 21, the contact time between the drink and the air will be longer, while when the drink flows into the mouth from the rear cup rim 22, the contact time between the drink and the air will be shorter. Such difference in contact time with the air can also promote the change of the flavor of the drink.

[0042] The front side eversion angle θ1 is within a range of 30 to 70 degrees, preferably, within a range of 35 to 60 degrees, and more preferably, within a range of 45 to 55 degrees, such as 48 degrees or 52 degrees.

[0043] The rear side outward turning angle θ2 is within the range of 0-15 degrees, preferably within the range of 0-10 degrees, that is, the cup edge 32 of the rear side 22 can be a vertical wall surface, not outward turning, or only outward turning at a small angle. The outward turning angle of the cup edge 32 is, for example, 6 degrees or 8 degrees.

[0044] The left side eversion angle θ3 is between 28 and 45 degrees, preferably between 30 and 40 degrees, such as 32 or 38 degrees. The right side eversion angle θ4 is between 20 and 45 degrees, preferably between 25 and 45 degrees, such as 28 or 34 degrees.

[0045] The left front side eversion angle θ5 is between 35 and 70 degrees. The left rear side eversion angle θ6 is between 5 and 30 degrees. The right front side eversion angle θ7 is between 35 and 70 degrees. The right rear side eversion angle θ8 is between 5 and 30 degrees. The eversion angle of the cup edge of the left area A (including the left front side, the left side and the left rear side) is between 5 and 70 degrees, preferably, between 8 and 66 degrees; the eversion angle of the cup edge of the right area B (including the right front side, the right side and the right rear side) is between 5 and 70 degrees, preferably, between 8 and 66 degrees.

[0046] In terms of specific design, the cup edges at different positions of the cup mouth 20 have different outward turning angles and different extension lengths.

[0047] The width D of the mouth 22 of the cup 10 is as follows: Figure 6 As shown, a width D of 4 cm to 14 cm is preferred, and in particular a width D of 5 cm to 10 cm can best present the flavor of the drinking liquid.

[0048] The present invention aims to provide a cup that can be used to taste coffee, wine, tea or other drinks, and can taste the different flavors of the drinks consumed, and can be used to taste various coffees, various wines and teas, such as coffees, wines and teas of different varieties and origins, including various wines such as white wine, whiskey, red wine, kaoliang wine, as well as black tea, green tea, oolong tea, etc. The present invention designs the cup 10 with an asymmetrical cup mouth, and drinks can be drunk from different positions of the cup edge, which can enhance the flavors of different aspects of the same drink.

[0049] When the user drinks the beverage from the rim 31 of the front side 21, the rim 31 has the largest eversion angle θ1 and the longest extension length. Because of the entrance angle, the beverage can enter the oral cavity more deeply, and the taste buds on the back of the tongue can taste the beverage. When the user drinks the beverage from the rim 32 of the back side 22, the rim 32 has the smallest eversion angle θ2 and the shortest extension length. Therefore, the beverage can enter the oral cavity from the mouth, and the taste buds on the front of the tongue can taste the beverage. Through the taste buds at different positions of the tongue to feel different tastes, when the user drinks the beverage from the front side 21 and the back side 22 of the cup 10, the taste buds at different positions will feel the beverage, and the drinker will feel different flavors of the same beverage. Similarly, when drinking the beverage from the rim of the left area A or the rim of the right area B, through the different eversion angles and different extension lengths of the rims, the beverage enters different positions of the oral cavity at different angles, and the taste buds at different positions of the tip of the tongue, the bottom of the tongue, and the sides of the tongue can taste the beverage. Therefore, the drinker can enjoy the same drink from different positions of the rim of the cup at 360 degrees and will feel different flavors without adding other condiments to change the flavor and taste of the drink.

[0050] For example, when a drinker enjoys hand-brewed coffee with the cup 10, if he drinks the coffee from the position where the cup rim is turned outward at a 40-degree angle, the coffee's floral, fruity, and sour flavors will be emphasized and felt, while if he drinks the coffee from the position where the cup rim is turned outward at a 9-degree angle, the coffee's nuts, cocoa, caramel, and other flavors will be emphasized, as if he is drinking coffee of different types and flavors.

[0051] The present invention uses a unique angle design of the cup rim to allow the unique flavor differences of various beverages such as coffee, tea, and wine to be tasted. When the cup rim is placed at a larger everted angle, the bright flavor of the beverage can be experienced, while when the cup rim is placed at a smaller everted angle, the beverage can be experienced with a thicker and richer flavor. The gradual angle design between the large and small everted angles allows the cup to have different flavors of the beverage from 360 degrees.

[0052] The cup of the present invention has been tested by a number of subjects and has been shown to provide different tastes when drinking beverages from the cup rim at different positions and different outward angles, thereby enhancing the fun and enjoyment of drinking.

[0053] When drinking, the spiral body 16 of the cup body 15 can guide the flow of the beverage and make the beverage collide with each other, making the beverage uniform and increasing its fluidity. For example, the spiral circumferential surface of the cup body 15 has the effect of shaking coffee to make the hand-brewed coffee uniform, and can also increase the flow speed of red wine and make the red wine contact with air.

[0054] It is understandable that the cup mouth has different positions such as the front, back, left, right, left front, left rear, right front and right rear; in practice, the cup mouth can have an outward-turned cup edge at at least two of the above-mentioned different positions, and the cup edge of the cup mouth at the at least two different positions forms at least two different outward-turned angles; the at least two different positions are any combination of the above-mentioned different positions, including: the front and the back, the front and the left, the front and the right, the front and the left front, the front and the left rear, the front and the right front, the front and the right rear, the back and the left, the back and the right, the back and the left front, the back and the left rear, the back and the right front, the back and the right rear, the left and the right, the left and the right front, the left and the right rear, the left and the left front, the left and the left rear, the right and the left front, the right and the left rear, the right and the right front, the right and the right rear, etc. Similarly, the cup rim can be set at at least three or at least four different positions of the cup mouth, and the cup rim of the cup mouth can form at least two, at least three or at least four different eversion angles. The at least three or at least four different positions are any combination of the above different positions.

[0055] The cup rim of the cup can be made of different thicknesses, for example, the front cup rim is thicker and the back cup rim is thinner, or the back cup rim is thicker and the front cup rim is thinner. In this way, when the beverage in the cup flows into the mouth from different thicknesses, it can have different temperature changes, resulting in changes in flavor.
