The cup opening 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 side 21 and the rear side 22. For example, the cup opening 20 can be divided into eight equal parts, so that the cup opening 20 has different positions of the front side 21, the rear side 22, a left side 23, a right side 24, a left front side 25, a left rear side 26, a right front side 27 and a right rear side 28. The left area A refers to a range on a left side of the cup opening 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; the right area B comprises a range on a right side of the cup opening 20 between the front side 21 and the rear side 22, including positions of the right side 24, the right front side 27 and the right rear side 28. The aforementioned eight equal parts are only an example, other ratios of equal parts can be made according to actual requirements, such as three equal parts, four equal parts, five equal parts, six equal parts, ten equal parts, twelve equal parts, sixteen equal parts, etc.

Please refer to FIGS. 5 to 8, the cup rim 30 of the cup opening 20 defines a cup rim 31 at the front side 21, a cup rim 32 at the rear side 22, a cup rim at the left area A and a cup rim at the right area B. The cup rim at the left area A comprises 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 at the right area B comprises 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.

In a preferred embodiment of the invention, the cup rim 30 of the cup opening 20 is made into an everted cup rim, that is, the cup rim 30 extends outwardly rather than inwardly, and the cup rim 30 has different everted angles at different positions.

FIG. 5 shows the cup rims 31 and 32 on the front side 21 and the rear side 22 of the cup opening 20 of the cup 10 and everted angles θ1 and 02 of the two cup rims 31 and 32. Each of the outwardly extending cup rims 31 to 38 is an inclined surface or a curved surface. Taking the longitudinal direction L as a reference, an everted angle described in this specification is an included angle between a surface (inclined surface or curved surface) of each of the cup rims and the longitudinal direction L of the cup 10, especially an included angle between an end edge of the cup rim and the longitudinal direction L.

In this embodiment, the everted angle θ1 of the cup rim 31 at the front side 21 (hereinafter referred to as a front everted angle) is greater than the everted angle θ2 of the cup rim 32 at the rear side 22 (hereinafter referred to as a rear everted angle). The cup rim 30 at the left area A of the cup opening 20 has at least one left area everted angle or a plurality of left area everted angles. Please refer to FIGS. 6 to 8, the left area everted angle can be formed by any one of or all of, but not limited to an everted angle θ5 of the cup rim 35 at the left front side 25, an everted angle θ3 of the cup rim 33 at the left side 23, and an everted angle θ6 of the cup rim 36 at the left rear side 26. When each of the cup rims at a plurality of positions in the left area A has an everted angle, the everted angles can be independent and preferably have different angle values from each other, and changes in the angles are not required to be continuously increased or decreased. It is preferably that an angle value of the at least one left area everted angle is different from an angle value of the front everted angle θ1 or an angle value of the rear everted angle θ2, so that the cup rim 30 of the cup 10 has two everted angles or more than two everted angles at different positions.

In this embodiment, the everted angle of the cup rim 30 in the left area A progressively and continuously decreases from the front side 21 toward the rear side 22. Please refer to FIG. 6 to FIG. 8, the everted angle θ5 of the rim 35 at the left front side 25 (hereinafter referred to as a left front everted angle) is smaller than the front everted angle θ1 of the front side 21, but greater than the everted angle θ3 of the cup rim 33 at the left side 23 (hereinafter referred to as a left everted angle); the everted angle θ6 of the cup rim 36 at the left rear side 26 (hereinafter referred to as a left rear everted angle) is smaller than the left everted angle θ3 of the cup rim 33 at the left side 23, but greater than the rear everted angle θ2 of the cup rim 32 at the rear side 22.

Similarly, the cup rim 30 at the right area B of the cup opening 20 has at least one right area everted angle or a plurality of right area everted angles. The right area everted angle can be formed by any one of or all of, but not limited to an everted angle θ7 of the cup rim 37 at the right front side 27, an everted angle θ4 of the cup rim 34 at the right side 24, and an everted angle θ8 of the cup rim 38 at the right rear side 28. When each of the cup rims at a plurality of positions in the right area B has an everted angle, the everted angles can be independent and preferably have different angle values from each other, and changes in the angles are not required to be continuously increased or decreased. It is preferably that an angle value of the at least one right area everted angle is different from an angle value of the front everted angle θ1 or an angle value of the rear everted angle θ2, so that the cup rim 30 of the cup 10 has two everted angles or more than two everted angles at different positions.

In this embodiment, the everted angle of the cup rim 30 in the right area B progressively and continuously decreases from the front side 21 toward the rear side 22. The everted angle θ7 of the cup rim 37 at the right front side 27 (hereinafter referred to as a right front everted angle) is smaller than the front everted angle θ1 of the front side 21, but greater than the everted angle θ4 of the cup rim 34 at the right side 24 (hereinafter referred to as a right everted angle); the everted angle θ8 of the cup rim 38 at the right rear side 28 (hereinafter referred to as a right rear everted angle) is smaller than the right everted angle θ4 of the cup rim 34 at the right side 24, but greater than the rear everted angle θ2 of the cup rim 32 at the rear side 22.

Therefore, among the cup rims 31 to 38 of the cup 10, the front everted angle θ1 is the largest everted angle, the rear everted angle θ2 is the smallest everted angle, the everted angles θ5, 03, 06 of the cup rims 25, 23, 26 of the left area A decrease progressively from the front side 21 toward the rear side 22 of the cup 10, the everted angles θ7, 04, 08 of the cup rims 27, 24, 28 in the right area B also decrease progressively from the front side to the rear side, and the cup rims 31 to 38 at different positions present different everted angles.

In addition, in this preferred embodiment, lengths of the cup rim 30 of the cup opening 20 extending outwardly from different positions of the cup rim 30 are different. As shown in FIG. 2 and FIG. 5 to FIG. 8, taking a center P of the cup body 15 as a reference, the cup rim 31 of the front side 21 has a longest outward extending length S1, and the cup rim 32 of the rear side 22 has a shortest outward extending length S2. Outward extending lengths of the cup rims 25, 23, 26 of the left area A also continuously decrease from the front side 21 toward the rear side 22 of the cup 10. That is, an outward extending length S4 of the cup rim 25 at the left front side is greater than an outward extending length S3 of the cup rim 23 at the left side, and the outward extending length S3 of the cup rim 23 at the left side is greater than an outward extending length S5 of the cup rim 26 at the left rear side. Similarly, outward extending lengths of the cup rims 27, 24, 28 of the right area B also decrease progressively from the front side 21 toward the rear side 22, and the outward extending lengths of the cup rims 27, 24, 28 are not the same. When a cold beverage or a hot beverage flows into an oral cavity from the cup rims with different extending lengths, a contact time between the beverage and the air will be different. For example, when a beverage flows into an oral cavity from the cup rim 21 on the front side, there will be a longer contact time between the beverage and the air. When a beverage flows into an oral cavity from the cup rim 22 on the rear side, the beverage will have a shorter contact time with the air. This difference in contact time with the air will promote changes in a flavor of a beverage.

The front everted angle θ1 is between 30 and 70 degrees, preferably between 35 and 60 degrees, and more preferably between 45 and 55 degrees, such as 48 degrees or 52 degrees.

The rear everted angle θ2 is between 0 and 15 degrees, preferably between 0 and 10 degrees. That is, the cup rim 32 of the rear side 22 can be an upright wall, not everted, or only everted at a small angle. An everted angle of the cup rim 32 is, for example, 6 degrees or 8 degrees.

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

The left front everted angle θ5 is between 35 and 70 degrees. The left rear everted angle θ6 is between 5 and 30 degrees. The right front everted angle θ7 is between 35 and 70 degrees. The right rear everted angle θ8 is between 5 and 30 degrees. An everted angle of the cup rim 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; an everted angle of the cup rim 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.

In terms of specific design, the cup rim 30 at different positions of the cup opening 20 has different everted angles and different extending lengths.

As shown in FIG. 6, a width D of the cup opening 20 of the cup 10 is preferably between 4 cm and 14 cm. In particular, the width D of 5 cm to 10 cm can best present a flavor of drinking a liquid.

The invention aims to provide a cup that can be used to taste coffee, wine, tea or other beverages, and can taste different flavors of beverages being drunk. The cup can be used to taste various types of coffee, various types of wine and tea, such as coffee, wine and tea of different varieties and origins, including white wine, whiskey, red wine, sorghum wine and other wine and spirits, as well as black tea, green tea, oolong tea, etc. In the invention, the cup 10 is designed with the asymmetrical cup opening 20, drinking beverages from the cup rim 30 of the cup 10 at different positions is capable of enhancing different flavors of a same beverage.

When a user drinks a beverage from the cup rim 31 on the front side 21, since the cup rim 31 has the largest everted angle θ1 and the longest extending length, the beverage can go deeper into an oral cavity due to an entering angle, and the beverage is tasted through taste buds on a back side of a tongue. When the user drinks a beverage from the cup rim 32 on the rear side 22, since the cup rim 32 has the smallest everted angle θ2 and the shortest extending length, the beverage can enter an oral cavity from an opening of the oral cavity, and the beverage is tasted through taste buds on a front side of a tongue. Different tastes are felt through taste buds at different positions of a tongue. When the user drinks a beverage from the front side 21 and the rear side 22 of the cup 10, taste buds at different positions will feel the beverage, thereby enabling the drinker to experience different flavors of a same beverage. Similarly, when drinking a beverage from the cup rim of the left area A or the cup rim of the right area B, the beverage enters different positions of an oral cavity at different angles through the different everted angles and the different extending lengths of the cup rims, and the beverage is tasted by taste buds at different positions on a tip of a tongue, a bottom of a tongue, and two sides of a tongue. Therefore, a drinker who enjoys a same cup of beverage from the cup rims at different positions from a 360-degree position will experience different flavors without adding other condiments to change flavor and taste of a beverage.

For example, when a drinker uses the cup 10 to enjoy a hand-brewed coffee, and drinks the coffee from the cup rim 30 at a position of an everted angle of 40 degrees, floral, fruity and sour flavors of the coffee will be emphasized and felt, while drinking the coffee from the cup rim at a position of an everted angle of 9 degrees, nutty, cocoa and caramel flavors will be emphasized, as if a drinker is drinking different types of coffee with different flavors.

By designing the cup rim 30 of the cup 10 with the unique everted angles, the invention enables experiencing differences of unique flavors of various beverages such as coffee, tea, wine. When drinking from the cup rim 30 with a larger everted angle, a drinker can experience a bright flavor of a beverage; when drinking from the cup rim 30 with a smaller everted angle, a drinker can experience a thicker and richer flavor of a beverage. The cup 10 with a design of the large and small progressive everted angles enables tasting different levels of unique flavors of various beverages from a 360-degree position of the cup rim 30.

Experiments carried out on subjects have shown that the cup 10 of the invention is capable of producing different taste sensations when drinking beverages from the cup rim 30 at different positions and different everted angles, thereby improving the pleasure and enjoyment of drinking.

When drinking a beverage, the spiral sheets 16 of the cup body 15 are capable of guiding the flow of the beverage, and allows the beverage to collide in the cup to mix the beverage evenly and increase its fluidity. For example, the cup body 15 with a spiral peripheral surface has a function of shaking coffee to make a hand-brewed coffee well-mixed, and also capable of increasing a flow speed of red wine to make the red wine contact with the air.

It can be understood that the cup opening has different positions of the front side, the rear side, the left side, the right side, the left front side, the left rear side, the right front side and the right rear side. in practice, the cup opening can have the everted cup rims at at least two of the above-mentioned different positions, and the cup opening forms at least two of the different everted angles at the cup rim 30 at the at least two different positions. The at least two different positions are any combinations of the above-mentioned different positions, including: the front side and the rear side, the front side and the left side, the front side and the right side, the front side and the left front side, the front side and the left rear side, the front side and the right front side, the front side and the right rear side, the rear side and the left side, the rear side and the right side, the rear side and the left front side, the rear side and left rear side, the rear side and the right front side, the rear side and the right rear side, the left side and the right side, the left side and the right front side, the left side and the right rear side, the left side and the left front side, the left side and the left rear side, the right side and the left front side, the right side and the left rear side, the right side and the right front side, the right side and the right rear side. Similarly, the cup opening can be provided with the everted cup rims at at least three or at least four of the above-mentioned different positions, and the cup rim of the cup opening forms at least two, at least three or at least four of the different everted angles. At least three or at least four of the different positions are any combinations of the above-mentioned different positions.

The cup rim of the cup can be made of different thicknesses, for example, the cup rim on the front side is thicker and the cup rim on the rear side is thinner, or the cup rim on the rear side is thicker and the cup rim on the front side is thinner. Thereby, when a beverage in the cup flows into an oral cavity from the cup rim with different thicknesses at different positions, different temperature changes can be provided, resulting in changes in flavor.

Although the invention has been disclosed as above with the embodiment, it is not intended to limit the invention. A person having ordinary skill in the art to which the invention pertains can make various changes and modifications without departing from the spirit and scope of the invention. Therefore, scope of protection of the invention shall be subject to what is defined in the pending claims.
