[0029] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of this application.

[0030] In order to meet the requirement of stacking the cup bodies after forming, the current stacking cups are designed with a step structure under the cup edge, and the step structure is overlapped with the cup edge of the lower cup body to achieve stacking of the cup bodies. However, the existence of the step structure affects the appearance of the cup body on the one hand, and on the other hand, when this structure is squeezed by a large external force, the cup bodies are still easily squeezed together, which affects the separation of cups.

[0031] In view of this, the utility model provides a stacking cup. By arranging a support structure on the inner wall surface of the cup body, when multiple stacking cups are stacked, the bottom of one of the stacking cups can be supported on the support structure of another stacking cup, thereby preventing the stacking cups from being excessively squeezed and affecting the use of the separate cups. Moreover, since the support structure is arranged on the inner side of the stacking cup, it does not affect the appearance of the stacking cup. In addition, the structural strength of the stacking cup can be enhanced to a certain extent through the support structure, thereby enhancing the ability of the stacking cup to resist deformation when it is squeezed. When multiple stacking cups are stacked, the support structures of the multiple stacking cups can jointly resist external forces, thereby enhancing the overall ability to resist deformation, which can improve the user experience.

[0032] Reference below Figure 1-Figure 5 A stacking cup 100 according to an embodiment of the present invention is described.

[0033] The stacking cups 100 of this embodiment can be stacked during packaging, transportation and use, that is, multiple stacking cups 100 are nested in layers, and among any two adjacent stacking cups 100 along the stacking direction, a partial structure of one of them along its own axial direction is embedded in the inner side of the other stacking cup 100, so as to reduce the space occupied by the multiple stacking cups 100.

[0034] Specifically, the stacking cup 100 may include a cup body 1 .

[0035] Combination Figure 1 and Figure 2 The cross-sectional shape of the cup body 1 can be circular, square or any other shape. The cup body 1 has a first end and a second end along the axial direction. The first end of the cup body 1 has an opening, and the second end of the cup body 1 is closed. For example, when the cup body 1 is placed vertically, the first end of the cup body 1 is the upper end of the cup body 1, and the second end of the cup body 1 is the bottom end of the cup body 1. In other words, the cup body 1 is a cup body 1 with an opening at the top.

[0036] The cross-sectional area of ​​the cup body 1 gradually decreases along the axial direction of the cup body 1 and from the first end to the second end. In this way, when multiple stacking cups 100 need to be stacked, the second end of the upper stacking cup 100 can be inserted into the lower stacking cup 100 from the first end of the lower stacking cup 100.

[0037] The inner wall surface of the cup body 1 is provided with a support structure 111, and the support structure 111 can extend along the circumference of the cup body 1, for example, the support structure 111 can be formed into a ring, or an arc segment. The support structure 111 can be a structure independently formed on the inner wall surface of the cup body 1, in which case, the outer wall of the cup body 1 does not form a concave-convex structure due to the provision of the support structure 111; or, the support structure 111 can also be formed by the side wall 11 of the cup body 1 protruding inwardly, in which case, the outer wall of the cup body 1 forms a concave structure due to the provision of the support structure 111.

[0038] The projection of the second end of the cup body 1 in the reference plane coincides with the projection of at least part of the support structure 111 in the reference plane, and the reference plane is perpendicular to the axis of the cup body 1. Thus, when any two stacking cups 100 are stacked, it can be ensured that the second end of one of the stacking cups 100 abuts against the support structure 111 on the other stacking cup 100 when the second end is inserted into the other stacking cup 100, thereby preventing the two stacking cups 100 from being too tightly fitted, increasing the difficulty of separation during use and making it inconvenient to use.

[0039] According to the stacking cup 100 of the embodiment of the utility model, by providing a support structure 111 on the inner wall surface of the cup body 1, when multiple stacking cups 100 are stacked, the bottom of one stacking cup 100 can be supported on the support structure 111 of another stacking cup 100, thereby preventing the stacking cups 100 from being excessively squeezed and affecting the use of separate cups. Moreover, since the support structure 111 is provided on the inner side of the stacking cup 100, the appearance of the stacking cup 100 is not affected. In addition, the structural strength of the stacking cup 100 can be enhanced to a certain extent through the support structure 111, thereby enhancing the ability of the stacking cup 100 to resist deformation when being squeezed. When multiple stacking cups 100 are stacked, the support structures 111 of the multiple stacking cups 100 can jointly resist external forces to further enhance the overall ability to resist deformation, which can improve the user experience.

[0040] In some embodiments, reference Figure 2 , Figure 4 and Figure 5 The cup body 1 includes a side wall 11 and a bottom wall 12, wherein the bottom wall 12 is located at the second end of the side wall 11, and the support structure 111 is formed by the side wall 11 protruding toward the inner side of the cup body 1. For example, the support structure 111 is formed by the side wall 11 protruding inwardly along the radial direction of the cup body 1. At this time, the outer surface corresponding to the support structure 111 is a recessed structure relative to other parts of the side wall 11.

[0041] In this way, when processing the stacking cup 100, the support structure 111 can be formed by bending, rolling, etc. the side wall 11. Compared with the solution of separately setting the support structure 111 on the inner wall surface of the cup body 1, the molding process of the stacking cup 100 is simpler and easier to process. In addition, the support structure 111 can enhance the strength of the cup body 1 to a certain extent, and improve the ability of the cup body 1 to resist impact and deformation. In addition, since the support structure 111 is a part of the side wall 11, when the support structure 111 is squeezed by another stacking cup 100, the squeezing force can be better dispersed to other areas of the side wall 11, thereby improving the support force for other stacking cups 100.

[0042] In some embodiments, in combination Figure 2 The support structure 111 may include a first side surface 1111 and a second side surface 1112. The first side surface 1111 and the second side surface 1112 are opposite and connected along the axial direction of the cup body 1. The first side surface 1111 and the inner ends of the second side surface 1112 are connected, and the connection may be an arc transition. The first side surface 1111 is located on the side of the second side surface 1112 facing the first end, that is, when two stacking cups 100 are stacked, the bottom end of one stacking cup 100 is supported on the first side surface 1111 of the other stacking cup 100, and the second side surface 1112 may play a role in supporting the first side surface 1111.

[0043] Among them, combined Figure 2 and Figure 5 At least one of the first side surface 1111 and the second side surface 1112 is a curved surface. For example, only the first side surface 1111 may be a curved surface, only the second side surface 1112 may be a curved surface, or both the first side surface 1111 and the second side surface 1112 may be curved surfaces. By making at least one of the first side surface 1111 and the second side surface 1112 a curved surface, when the support structure 111 is subjected to a force from another stacking cup 100, the curved surface can better disperse the force to other areas of the side wall 11, thereby improving the support force for other stacking cups 100.

[0044] In some embodiments, the cross-section of the first side surface 1111 is an arc, and the cross-section of the second side surface 1112 is a straight line. In this way, when the support structure 111 is subjected to an axial force from another stacking cup 100, the first side surface 1111 exerts a pulling force on other areas of the side wall 11, and can better disperse the external force to other areas, thereby ensuring the stability of the shape of the support structure 111 to better support another stacking cup 100, and the cross-section of the second side surface 1112 is a straight line, which can provide certain support and buffering effects for the first arc surface.

[0045] In some embodiments, the support structure 111 is formed into a ring extending along the circumference of the cup body 1, so that the support structure 111 can support another stacked cup 100 in the circumferential direction, with a better supporting effect and conducive to better dispersing the force.

[0046] Alternatively, in some other embodiments, the support structure 111 includes a plurality of support segments spaced apart along the circumference of the cup body 1 , so that the support structure 111 has a relatively simple structure and is easy to process.

[0047] In some embodiments, reference Figure 2 , the height h of the support structure 111 protruding toward the inner side of the cup body 1 is 1.5mm-10mm. Specifically, taking the cross-section of the other parts of the side wall 11 of the cup body 1 except the support structure 111 as the reference line, the vertical distance between the inner end of the support structure 111 and the reference line is the height of the support structure 111 protruding toward the inner side of the cup body 1. For example, the height h of the support structure 111 protruding toward the inner side of the cup body 1 is 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm or 10mm. Of course, the utility model is not limited to this. The height of the support structure 111 protruding toward the inner side of the cup body 1 can be reasonably selected within the above range according to actual needs.

[0048] In this way, on the one hand, it is possible to avoid the protruding height of the support structure 111 being too small, for example, when it is less than 1.5 mm, when multiple stacking cups 100 are stacked, the bottom end of the inner stacking cup 100 cannot be effectively and stably supported on the support structure 111 of the outer stacking cup 100. On the other hand, it is possible to avoid the protruding height of the support structure 111 being too large, for example, when it is greater than 10 mm, the internal space occupied by the support structure 111 is too large, resulting in a reduction in the effective volume of the stacking cup 100. It is also beneficial to demolding the cup body 1 during the processing process, reducing the process difficulty and improving production efficiency.

[0049] In some embodiments, reference Figure 2 , the distance d between the support structure 111 and the second end of the cup body 1 is d≥10mm, that is, the distance d between the support structure 111 and the bottom of the cup is d≥10mm, for example, the distance d between the support structure 111 and the bottom of the cup can be 10mm, 11mm, 12mm, 15mm, 18mm, 20mm or more, of course, the utility model is not limited to this, the distance d between the support structure 111 and the bottom of the cup can be reasonably designed according to factors such as the overall height of the stacked cup 100. In this way, after the stacked cups 100 are stacked, there can be a suitable gap between the cup bodies 1, ensuring that there is no close contact between the side wall 11 of the upper stacked cup 100 and the side wall 11 of the lower stacked cup 100, making it easier to separate the cups when using.

[0050] In some embodiments, in combination Figure 2 , Figure 4 and Figure 5 The second end of the cup body 1 is also provided with a limiting protrusion 112, which protrudes toward the outside of the cup body 1, and the limiting protrusion 112 protrudes radially outward from the portion of the side wall 11 adjacent to the second end of the cup body 1. The stacking cup 100 may also include: a label 2. The label 2 is sleeved on the outer wall of the cup body 1, and the label 2 is suitable for being attached to the side wall 11 of the cup body 1. It can be understood that the side wall 11 of the cup body 1 is spaced apart from the label 2 at the support structure 111, so that the appearance of the cup body 1 is more flat and beautiful.

[0051] In the case where the limiting protrusion 112 is not provided, since the cross-sectional area of ​​the cup body 1 gradually decreases from the first end to the second end, the minimum cross-sectional area of ​​the label 2 (i.e., the cross-sectional area of ​​the second end of the label 2) is still larger than the cross-sectional area of ​​the second end of the cup body 1, resulting in the possibility that the label 2 will fall off from the second end along the axial direction of the cup body 1. In this embodiment, in order to ensure that the label 2 is stably located outside the cup body 1, a limiting protrusion 112 protruding outward is provided at the second end of the cup body 1, and one end of the label 2 along the axial direction of the cup body 1 is abutted against the limiting protrusion 112, thereby preventing the label 2 from falling off.

[0052] Understandably, reference Figure 4 and Figure 5When the stacking cups 100 are stacked, the limiting protrusion 112 at the bottom end of the upper stacking cup 100 can be supported on the first side surface 1111 of the supporting structure 111 of the lower stacking cup 100. Therefore, in order to reduce the squeezing force of the limiting protrusion 112 of the upper stacking cup 100 on the first side surface 1111 of the supporting structure 111 of the lower stacking cup 100, part of the outer surface of the limiting protrusion 112 of the stacking cup 100 can be set to be parallel to the first side surface 1111 of the supporting structure 111. In this way, the limiting protrusion 112 of the upper stacking cup 100 and the first side surface 1111 of the supporting structure 111 of the lower stacking cup 100 form a surface contact, which can reduce the squeezing force and better protect the structural integrity of the stacking cup 100.

[0053] In some embodiments, the height of the limiting protrusion 112 protruding outward is 0.3mm-3mm. For example, the cross section of the other parts of the side wall 11 of the cup body 1 except the support structure 111 and the limiting protrusion 112 is taken as the reference line, and the vertical distance between the outer end of the limiting protrusion 112 and the reference line is the protruding height of the limiting protrusion 112. For example, the protruding height of the limiting protrusion 112 radially outward is 0.3mm, 0.5mm, 0.7mm, 0.8mm, 0.9mm, 1mm, 1.5mm, 2mm, 2.5mm or 3mm. Of course, the utility model is not limited to this. The protruding height of the limiting protrusion 112 radially outward can be reasonably selected within the above range according to actual needs. In this way, on the one hand, it is avoided that the protruding height of the limiting protrusion is too small, for example, when it is less than 0.3mm, it cannot effectively prevent the label 2 from falling off. On the other hand, it is avoided that the protruding height of the limiting protrusion 112 is too large, for example, when it is greater than 3mm, the appearance of the stacking cup 100 is reduced.

[0054] In some embodiments, the limiting protrusion 112 can be formed by a portion of the side wall 11 adjacent to the second end protruding outward, so that the molding process of the stacking cup 100 is relatively simple and easy to implement.

[0055] In some embodiments, the outer circumference of the first end of the cup body 1 is further provided with a cup edge 13, for example, the cup edge 13 is located at the top of the side wall 11 of the cup body 1, and the cup edge 13 extends along the circumference of the cup body 1. By providing the cup edge 13, on the one hand, it can play a role in limiting the top of the label 2, and on the other hand, it can strengthen the structural strength of the opening of the cup body 1, and it is also convenient for users to hold.

[0056] In some embodiments, part of the structure of the bottom wall 12 of the cup body 1 protrudes toward the first end of the cup body 1. In this way, the stability of the stacking cup 100 when placed on a supporting surface can be increased. For example, the supporting surface can be a table top, a windowsill, the ground or other surfaces. In addition, the concave-convex structure helps to enhance the strength of the bottom wall 12 of the cup body 1 and can better resist deformation.

[0057] In some embodiments, the cup body 1 can be at least one of a plastic part, a ceramic part, a glass part, a metal part, a wooden part, a paper part, and a composite material part. This makes it easy to process and shape, and the cost is low.

[0058] Preferably, the cup body 1 may be a plastic part, for example, the cup body 1 may be a polypropylene part, so that the cup body 1 can be conveniently subjected to a thermoforming process to form the support structure 111 and the limiting protrusion 112. Moreover, the cost is low and the service life is long.

[0059] The following takes the cup body 1 as a plastic part and provided with a support structure 111 as an example to illustrate the molding process of the stacking cup 100 of this embodiment:

[0063] Cool down after keeping warm for a preset time;

[0064] The mold is opened, and the formed stacking cup 100 is cut from the sheet through die cutting.

[0065] In this way, the stacking cup 100 with the support structure 111 in the above embodiment is formed. The molding process of the stacking cup 100 is relatively simple, easy to manufacture, and has high production efficiency.
