Description

Technical Field

[0001] This utility model relates to the field of stackable cup technology, and more specifically, to a stackable cup. Background Technology

[0002] Stacking cups can be stacked to create various shapes and can be nested together for storage, making them a novel toy that can develop users' manual dexterity. For example, an existing children's stacking cup with publication number CN218608020U, while allowing stacking, requires air holes at the bottom of the cups for venting to reduce air pressure interference during stacking. This compromises the inherent properties of the cups, such as their liquid-holding characteristics, and consequently, the integrity of the cup structure. Therefore, this paper proposes a new type of stacking cup to address these issues. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a stacking cup to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a stackable cup, comprising a cup body and a positioning boss, wherein the cup body has a continuous gradient taper and the positioning boss covers the inner edge of the bottom of the cup body.

[0005] Preferably, the upper edge of the positioning boss has several sets of air circulation grooves evenly distributed along the circumference.

[0006] Preferably, the bottom of the cup body is provided with a cup bottom that matches the positioning boss.

[0007] Preferably, two adjacent sets of cups are stacked to form an axial nest by taper matching.

[0008] Preferably, the diameter of the upper edge of the positioning boss is smaller than the diameter of the cup bottom.

[0009] The technical effects and advantages of this utility model are as follows:

[0010] Compared with existing technologies, this stacking cup can utilize the "conical" contraction of the cup body to form a self-centering effect, ensuring that the cup body automatically corrects the center deviation when stacked, and the cup body has no additional destructive venting holes.

[0011] Compared with existing technologies, this stacking cup has the advantage that, when two adjacent sets of cups are stacked, they form an axial nest by matching their tapers, and the nesting gap allows air to enter and exit along the airflow groove, ensuring that the stacking process is not blocked by air pressure.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] The present application will be further described in detail below with reference to the accompanying drawings.

[0021] Please see Figures 1-5 In this embodiment of the present invention, a stacking cup includes a cup body 1 and a positioning boss 2. The cup body 1 has a continuous gradient taper. The top opening diameter of the cup body 1 is larger and the bottom diameter is smaller. The cup body 1 is tapered in an overall "conical" shape, and the diameter is linearly reduced along the height (axial direction) of the cup body 1. The outer wall taper of the lower cup body 1 is consistent with the inner wall taper of the upper cup body 1, forming a self-centering effect to ensure that the cup body 1 automatically corrects the center deviation when stacked. The positioning boss 2 covers the inner edge of the bottom of the cup body 1.

[0022] The bottom of the cup body 1 is provided with a cup bottom 11 that matches the positioning boss 2. When two adjacent cup bodies 1 are nested, the cup bottom 11 of the upper cup body 1 abuts against the positioning boss 2 provided on the inner edge of the bottom of the lower cup body 1, so that the stacking height of any two cup bodies 1 can be kept consistent.

[0023] When two adjacent cup bodies 1 are stacked, they form an axial nesting through tapered matching, creating a nesting gap. Multiple cup bodies 1 achieve tight stacking through axial nesting with matching tapered shapes. Several sets of airflow grooves 21 are evenly distributed along the circumference of the upper edge of the positioning boss 2, while avoiding the vacuum adsorption jamming problem caused by the straight wall design. As the cup body 1 descends axially, the outer wall conical surface gradually fits together, and the airflow grooves 21 begin to guide airflow. Then, as the upper cup body 1 moves downward, the airflow flows out along the airflow grooves 21 and is further guided out through the nesting gap, ensuring the stacking process is smooth. It will not be blocked by air pressure; when it is necessary to separate the upper cup body 1, the external air enters quickly along the nesting gap and enters the interior of the lower cup body 1 along the air circulation groove 21, eliminating the negative pressure adsorption force and ensuring a smooth separation process. The upper edge diameter of the positioning boss 2 is smaller than the diameter of the cup bottom 11, so that when the two stacked cups are stacked, the cup bottom 11 of the upper stacked cup will not sink to the inner bottom surface of the lower stacked cup due to the limiting effect of the positioning boss 2, and the height of the two stacked cups can be kept consistent when stacked.

[0024] The working process of this utility model is as follows: When using the stacking cup, because the cup body 1 has a continuous gradual taper, when stacking, the outer wall taper of the lower cup body 1 is consistent with the inner wall taper of the upper cup body 1, forming a self-centering effect, ensuring that the cup body 1 automatically corrects the center deviation when stacking. When the upper cup body 1 moves downward, the airflow flows out along the flow groove 21, and is then guided out by the nesting gap, ensuring that the stacking process is not blocked by air pressure.

[0025] Furthermore, since the two adjacent cup bodies 1 are stacked to form an axial nesting through tapered matching, and by utilizing the nesting gap, when it is necessary to separate the upper cup body 1, external air enters quickly along the nesting gap and enters the interior of the lower cup body 1 along the air circulation groove 21, eliminating negative pressure adsorption force and avoiding adsorption jamming caused by negative pressure. Moreover, the cup body 1 as a whole maintains the inherent properties of the cup and can hold liquids, etc., without the need to drill destructive vent holes for venting.
