[0022] In order to make the above objectives, features and advantages of the present application more apparent, specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced in a number of different ways beyond the specific embodiments described and it is to be understood that the present application is not limited to the specific embodiments described below.
[0023] It should be noted that when an element is referred to as being "on" or "set on" another element, it can be directly on the other element or there can be an intervening element. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or there can be an intervening element. The terms "vertical", "horizontal", "upper", "lower", "left", "right", and similar expressions used in the description of the specification are used for the purpose of illustration only and do not indicate the only orientation of the embodiments.
[0024] In addition, the terms "first", "second", and the like are used only for descriptive purposes and do not indicate or imply relative importance or a quantity of the indicated technical features. Thus, a feature defined with "first", "second" can explicitly or implicitly include at least one of the features. In the description of the present application, the meaning of "a plurality of" is at least two, such as two, three, etc., unless otherwise explicitly specified and limited.
[0025] In the present application, unless otherwise explicitly specified and limited, "on", "under", "above", and "over" of a first feature to a second feature can be that the first feature is in direct contact with the second feature, or the first feature is indirectly in contact with the second feature through an intermediate medium. Moreover, "above", "over", and "on" of the first feature to the second feature can be that the first feature is directly above or obliquely above the second feature, or only indicates that the first feature is horizontally higher than the second feature. "Below", "under", and "underneath" of the first feature to the second feature can be that the first feature is directly below or obliquely below the second feature, or only indicates that the first feature is horizontally lower than the second feature.
[0026] Unless otherwise defined, all technical and scientific terms used in the application's specification are intended to have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the application's specification is for describing particular embodiments only and is not intended to be limiting of the application. The use of the terms "and / or" and "one or more of the following" includes any and all combinations of one or more of the associated listed items.
[0027] Referring to Figure 1 and Figure 2 , the application provides a paper cup 100, which comprises a base 10 and a cup barrel 20 connected with each other, the cup barrel 20 comprises three side walls 21 connected in sequence along the circumference of the base 10, the three side walls 21 are arranged to form a triangular structure, and an arc-shaped transition section 22 is arranged at the connection between two adjacent side walls 21, the arc-shaped transition section 22 protrudes outwardly in the direction away from the axis of the cup barrel 20. By arranging the three side walls 21 to form a triangular structure, the triangular structure is more stable, so that the cup barrel 20 is less likely to deform when a user holds the cup barrel 20 or the cup barrel 20 is subjected to extrusion. In addition, by arranging the arc-shaped transition section 22 at the connection between two adjacent side walls 21, the connection between the two adjacent side walls 21 is prevented from forming a sharp corner to scratch the user, so that the user's experience can be improved.
[0028] Optionally, in an embodiment, as shown in Figure 5 , the three side walls 21 are arranged to form an approximately equilateral triangular support structure.
[0029] As shown in Figure 2 , the end of the cup barrel 20 away from the base 10 is provided with a rolled edge 23, one end of the rolled edge 23 is connected to the cup barrel 20, and the other end is rolled towards the outside or the inside of the cup barrel 20. It can be understood that the rolled edge 23 not only can prevent the edge of the cup barrel 20 from scratching the user to improve the user's experience, but also can improve the strength of the paper cup 100.
[0030] The base 10 is arranged in the cup barrel 20 and is adhesively fixed to the cup barrel 20.
[0031] Specifically, as shown in Figure 3 , the end of the cup barrel 20 close to the base 10 is folded towards the inside of the cup barrel 20 and arranged to form a sandwiched space 24, the side wall of the base 10 is sandwiched in the sandwiched space 24 and adhesively fixed to the barrel wall of the cup barrel 20. In this way, the adhesive area of the cup barrel 20 and the base 10 can be increased, so that the cup barrel 20 and the base 10 are more firmly adhesively fixed. The cup barrel 20 and the base 10 can be adhesively fixed by a rolling adhesive process.
[0032] Optionally, referring to Figure 5, the arc-shaped transition section 22 is configured to extend in a circular arc shape, and a central angle of the arc-shaped transition section 22 is α, and 130°≤α≤150°. It can be understood that if α is too small, it is difficult to protect the user; if α is too large, it will affect the structural strength of the cup 100. Therefore, setting 50°≤α≤70° can not only make the arc-shaped transition section 22 have a protective effect on the user, but also be beneficial to ensure the structural strength of the cup 100.
[0033] For example, the value of α can be 130°, 135°, 140°, 150°, etc., as long as the value of α is within the above range, which will not be listed one by one here. However, the arc-shaped transition section 22 can also be configured to extend in a curved shape.
[0034] Exemplarily, in an embodiment, as shown in Figure 5 , the values of the central angles α corresponding to the three arc-shaped transition sections 22 are equal.
[0035] Please refer to Figure 1 , at least one side wall 21 is provided with a recessed section 211, which is recessed in the direction close to the axis of the cup 100, and forms a groove 212 on the outer surface of the side wall 21. It can be understood that when the user holds the cup 100, the groove 212 can be used to place the user's fingers, thereby facilitating the user to hold and place the paper cup 100.
[0036] Further, the recessed section 211 is configured to extend in a circular arc shape.
[0037] Further, the three side walls 21 are defined as a first side wall 201, a second side wall 202 and a third side wall 203, the recessed section 211 is arranged at the middle part of the first side wall 201, and the second side wall 202 and the third side wall 203 are symmetrically distributed on both sides of the recessed section 211. In this way, not only does the shape of the paper cup 100 form a heart shape, but also it is more beautiful and regular, and easy to process.
[0038] The following describes three arrangement forms of the first side wall 201, the second side wall 202 and the third side wall 203.
[0039] Embodiment one
[0040] As shown in Figure 1 , the second side wall 202 and the third side wall 203 are both configured to extend in a straight line shape. In this way, the second side wall 202 and the third side wall 203 have a simple shape, thereby facilitating to reduce the processing difficulty of the paper cup 100.
[0041] Embodiment two
[0042] As shown in Figure 4As shown, the second side wall 202 and the third side wall 203 are configured to extend in a circular arc shape, and the second side wall 202 and the third side wall 203 are respectively convex outwardly towards a direction away from the axis of the cup 20.
[0043] Embodiment Three
[0044] As shown, the first side wall 201, the second side wall 202 and the third side wall 203 are respectively provided with recessed sections 211. It can be understood that in this way, the user can hold the cup 20 from different directions. Figure 5
[0045] The technical features of the above embodiments can be combined in any manner. In order to make the description simple, all possible combinations of the technical features in the above embodiments are not described, however, as long as the combinations of the technical features do not contradict, they should be considered as the scope of the present disclosure.
[0046] The above embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the present application. It should be pointed out that for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
