[0036] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the accompanying drawings, the same reference numerals represent the same or similar components, or the same or similar steps.

[0037] In order to solve the problem in the prior art that most disposable plastic cups increase the strength of the cup body by increasing the wall thickness, which leads to increased production material costs and waste of resources, the side wall of the disposable plastic cup in the embodiment of the utility model is provided with two texture structures. Compared with the situation where providing one texture structure can only strengthen part of the structure, providing two texture structures can increase the overall structural strength of the water cup, which is beneficial to improving the heat resistance and stiffness of the water cup and further reducing production costs.

[0038] The utility model provides a disposable plastic cup (hereinafter referred to as water cup or plastic cup), such as Figure 1As shown, the water cup includes a cup body with an open top surface, and the cup body includes an opening portion 11, a side wall portion 12 and a base 13. The side wall portion 12 is located between the opening portion 11 and the base 13, the upper side surface of the side wall portion 12 is adjacent to the opening portion 11, and the bottom surface of the side wall portion 12 is adjacent to the base 13.

[0039] The plastic cup in the embodiment of the present invention is generally configured as an opening structure that is wide at the top and narrow at the bottom, which is not only conducive to the outflow of liquid inside the cup body, but also can disperse the pressure of the internal liquid on the side wall portion 12, which is conducive to reducing the pressure on the side wall portion 12 and improving the stability of the structure.

[0040] The side wall portion 12 has a first texture structure and a second texture structure. The first texture structure and the second texture structure are respectively arranged at the upper part and the lower part of the side wall portion 12, and are both located on the peripheral surface of the side wall portion 12. There is a transition section 16 between the first texture structure and the second texture structure.

[0041] Texture is a textured structure applied to the surface of an object, typically exhibiting various crisscrossing, uneven texture variations. A first texture and a second texture are respectively applied to the upper and lower portions of the sidewall 12. Different textures can be applied based on the stresses experienced by different parts of the cup body. For example, the lower portion of the sidewall 12 is primarily affected by the gravity of the internal liquid, so the second texture can be designed to enhance longitudinal strength or stiffness. The upper portion of the sidewall 12 is susceptible to lateral pressure, and considering actual usage scenarios, the first texture can be designed to enhance lateral strength.

[0042] The disposable plastic cup in the embodiment of the present invention is provided with a first texture structure and a second texture structure on the side wall portion 12. This replaces the flat side wall of a typical plastic cup with a texture structure having raised or recessed structures. This allows for thinner side walls to achieve greater structural strength and hardness, which helps reduce production materials and enhances the design of the cup. The first texture structure and the second texture structure are respectively arranged at the upper and lower portions of the side wall portion, covering a larger area of ​​the side wall portion. Compared to a cup without a texture structure or with only one texture structure, a cup with two texture structures has a higher overall structural strength and better stability during use. It also saves more production materials, thereby further reducing production costs.

[0043] In some embodiments, as Figure 2As shown, the second texture structure is a sloped surface block texture structure 15, which includes a sloped surface block 151. The sloped surface block 151 has an upper edge 151-1, a lower edge 151-2, a left edge 151-3 and a right edge 151-4. The upper edge 151-1 and the lower edge 151-2 are parallel to each other and arranged in the horizontal direction, and the left edge 151-3 and the right edge 151-4 are parallel to each other and arranged obliquely relative to the horizontal direction. Figure 7 As shown in the expanded schematic diagram of the bevel surface block texture structure, because the left edge 151-3 and the right edge 151-4 are at an angle to the horizontal, and the upper edge 151-1 and the right edge 151-4 are parallel to the horizontal, the bevel surface block 151 can be configured as a parallelogram. In the actual structure of the side wall portion 12, the parallelogram-shaped bevel surface block 151 is arranged at the lower portion of the side wall portion 12, forming a vertical torsion structure that twists in a clockwise or counterclockwise direction. Compared with a conventional cylindrical vertical torsion structure, it has better structural stability and lateral pressure resistance. The inclined left and right edges also act as reinforcing ribs, dispersing the pressure of the bevel surface block 151 in the horizontal and vertical directions, which helps to improve the stiffness and pressure resistance of the side wall portion 12.

[0044] It should be clarified that although the upper edge 151-1 and the lower edge 151-2 of the above-mentioned inclined surface block 151 are represented by straight lines in the expanded schematic diagram of the inclined surface block texture structure, they do not represent their actual structural shape. Since the peripheral surface of the side wall portion 12 is a curved surface with an arc, the upper edge 151-1 and the lower edge 151-2 are set as arcs or circular arcs in the actual structure, and the same applies to the left edge 151-3 and the right edge 151-4 of the inclined surface block 151.

[0045] In some embodiments, the bevel block texture structure 15 is provided with at least two bevel blocks 151, each of which has a bevel groove 152 between them. The widths of the bevel grooves 152 are equal, so that the bevel blocks 151 are arranged at equal intervals. The widths of the bevel blocks 151 are greater than, less than, or equal to the widths of the bevel grooves 152. The equally spaced bevel blocks 151 and bevel grooves 152 are arranged in a centrally symmetrical manner, so that the center of gravity of the sidewall portion 12 remains on the central axis of the water cup structure, which is beneficial to the stability of the cup structure and also enhances the visual aesthetics.

[0046] In some embodiments, the inclined surface block texture structure 15 is provided with six inclined surface blocks 151. The width of the inclined surface block 151 is greater than the width of the inclined surface groove 152. The horizontal projection of the upper edge 151-1 of the inclined surface block 151 partially overlaps with the lower edge 151-2 of the inclined surface block 151 on its left side, or the horizontal projection of the upper edge 151-1 of the inclined surface block 151 partially overlaps with the lower edge 151-2 of the inclined surface block 151 on its right side. The number of inclined surface blocks can be designed according to the actual situation of the water cup, such as eight or other numbers of inclined surface blocks 151.

[0047] The inclined surface block 151 and the inclined surface groove 152 have a specific relationship, such as Figure 7 As shown, the inclination angle of the inclined surface block 151 is α, the length of the left edge 151-3 of the inclined surface block 151 is L, the lateral width of the inclined surface block 151 is B1, and the lateral width of the inclined surface groove 152 is B2. The size of B2 is configured to satisfy the formula: B2 < L * cos a, so that the horizontal projection of the upper edge 151-1 of the inclined surface block 151 can cover the inclined surface block 151 adjacent to the left or right, and a structure similar to staggered stacking can be formed in the vertical direction, which is beneficial to improving the structural strength and stability of the side wall portion 12.

[0048] Including but not limited to this expression, the vertical reference line at the leftmost end of the inclined surface block 151 is located on the left side of the vertical reference line at the rightmost end of another inclined surface block adjacent to the left, or the vertical reference line at the rightmost end of the inclined surface block 151 is located on the right side of the vertical reference line at the leftmost end of another inclined surface block adjacent to the right. In this expression, the left and right edges of the inclined surface groove 152 can be used as the reinforcing rib structure of the side wall portion 12, which can effectively improve the stability and structural stiffness. <00001​​​​​​​

[0051] In some embodiments, as Figure 2 As shown, the outer diameter of the upper side of the transition section 16 is larger than the outer diameter of the lower side of the transition section 16. The transition section 16 is set to a structure with a larger upper portion and a smaller lower portion, which can divide the surface of the side wall portion 12 into different stepped structures. The inclined surface of the transition section 16 can also serve as a reinforcing rib structure of the side wall portion 12, which is beneficial to improving the overall strength of the side wall portion 12 structure.

[0052] In some embodiments, the angle between the inclined surface block 151 and the horizontal reference plane is 10° to 80°. Figure 7 As shown, the angle between the left and right edges of the bevel block 151 and the horizontal direction is the angle α between the bevel block 151 and the horizontal reference plane. The magnitude of angle α is related to the degree of inclination of the bevel block 151. For example, a smaller angle indicates a greater inclination of the bevel block 151, while a larger angle indicates a smaller inclination. The magnitude of angle α is dependent on factors such as the actual cup size and the number of bevel blocks 151. Adjusting angle α based on actual design needs can effectively improve the structural strength of the cup.

[0053] In some embodiments, as Figure 3 As shown, the first texture structure is a diamond-shaped texture structure 14, which includes a plurality of adjacently arranged diamond-shaped protrusions 141, including but not limited to these. The first texture structure can also be configured as a protrusion structure with other shapes, such as polygonal, circular, and elliptical shapes. The adjacently arranged protrusion structure can be arranged in a matrix or staggered arrangement. The staggered arrangement is more dense than the matrix arrangement, but the processing method and steps are also more complicated. It can be set according to the actual design situation. The diamond-shaped texture structure 14 not only improves the structural strength of the side wall portion 12, but the staggered grooves between the protrusions can also serve as a reinforcing rib structure for the side wall portion 12, improving the stability and pressure resistance of the cup body. In addition, the diamond-shaped texture structure 14 can also improve the heat resistance and cold resistance of the water cup. For example, when using the water cup to hold boiling water, the diamond-shaped texture structure 14 can effectively reduce the heat transferred to the skin by reducing the contact area between the skin and the cup wall, thereby preventing burns on the user's hands when holding the water cup.

[0054] In some embodiments, the area of ​​the diamond-shaped protrusions on the lower portion of the sidewall portion 12 is greater than the area of ​​the diamond-shaped protrusions on the upper portion of the sidewall portion 12. In the two adjacent rows of diamond-shaped protrusions arranged above and below the diamond-shaped texture structure 14, the area of ​​the diamond-shaped protrusions in the lower row is greater than the area of ​​the diamond-shaped protrusions in the upper row. The first texture structure can be configured as a gradient diamond-shaped texture structure 14, with the number of diamond-shaped protrusions 141 gradually increasing from bottom to top, so that the upper and lower portions of the cup body structure, which is larger at the top and smaller at the bottom, have the same structural strength. Visually, the first texture structure becomes increasingly complex from bottom to top, and the gradient diamond-shaped texture structure 14 presents a gradient shape effect, which helps enhance the design aesthetics and visual appeal of the cup body. Furthermore, the area size of the diamond-shaped protrusions 141 can also be adjusted based on the processing accuracy of the actual production equipment.

[0055] As a preferred embodiment, the diamond-shaped texture structure 14 on the upper portion of the sidewall 12 and the beveled surface block texture structure 15 on the lower portion can be configured to have a complex upper-lower structure, i.e., the texture lines on the upper portion of the cup body are more complex than those on the lower portion. This creates a distinct hierarchy and a clear distinction between primary and secondary elements, satisfying both visual aesthetics and enhancing the cup's usability. During use, both the design of the exterior and the heat resistance and stiffness of the structure are improved, allowing users to experience the charm of the design and the improvement of product quality while enjoying their beverages.

[0056] In some embodiments, as Figure 4 As shown, the base 13 includes at least two recessed portions 131, each of which is evenly distributed around the circumference of the base 13. The recessed portions 131 enhance the structural strength of the base 13, allowing the cup bottom to withstand greater pressure. As a supporting structure for the plastic cup, the recessed portions 131 help maintain the cup's stability. Furthermore, the recessed portions 131 prevent the cups from getting stuck together when multiple cups are stacked, thereby improving the practicality and convenience of the plastic cup.

[0057] In some embodiments, the cup body is an integrally formed structure formed by injection molding or blow molding. The disposable plastic cup of the present invention can have a volume of 200-600 ml, for example, 250 ml. It can be made of PP (polypropylene), which is colorless, odorless, non-toxic, and translucent, making it suitable for food packaging, household goods, automobiles, optical fiber, and other fields.
