[0027] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings.
[0028] like Figures 1 to 6 As shown, this embodiment provides a cup, including a cup body 3 with a top opening, an annular cup rim 1 and an annular step support structure 2, the step support structure 2 is connected between the top opening of the cup body 3 and the cup rim 1, the side wall of the cup body 3 is a conical structure with a diameter gradually decreasing from the top to the bottom; the side wall of the step support structure 2 is a conical structure with a diameter gradually increasing from the top to the bottom, and a plurality of exhaust grooves 4 are circumferentially spaced on the bottom outer wall of the step support structure 2.
[0029] When the cups are stacked, the step bottom surface 22 of the step support structure 2 of the upper cup overlaps the cup edge 1 of the lower cup, and a certain gap is formed between the outer side wall 312 of the cup body 3 of the upper cup and the inner side wall 311 of the cup body 3 of the lower cup. The size of the gap is related to the height of the step support structure 2 and the taper of the side wall of the cup body 3. When the height of the step support structure 2 is lower and the taper of the side wall of the cup body 3 is smaller, the gap is smaller. Generally, in order to make the overall cup coordinated and beautiful, the height of the step support structure 2 is relatively low. In order to make the cup capacity as large as possible, the taper of the side wall of the cup body 3 is relatively small. This will result in a smaller gap between the side walls of the two cups.
[0030] When stacked, the upper cup falls into the lower cup, so that the air between the outer wall 321 of the upper cup bottom and the inner wall 322 of the lower cup bottom is squeezed out, forming a low-pressure area, while the air in the upper cup is still a high-pressure area. Since the gap between the cups is small, and the step bottom surface 22 of the step support structure 2 of the upper cup overlaps the cup edge 1 of the lower cup, it will cause the high and low pressure areas to be unable to form good air flow, causing the two cups to be adsorbed together for a long time, and the lower cup cannot be well separated from the upper cup, which will cause the two cups to stick tightly together, making it difficult to separate the two cups when they need to be separated later.
[0031] In this embodiment, after adding a groove-shaped exhaust structure (exhaust groove 4) to the step support structure 2, the outer wall 321 of the bottom of the upper cup and the inner wall 322 of the bottom of the lower cup can be connected to the outside air, which can promote the air flow of the high and low pressure areas inside and outside, so that the high and low pressure areas gradually tend to balance, and the two cups will be separated. In addition, in order to further prevent the cups from being squeezed together, the step support structure 2 of the cup is not designed to be vertical to the cup edge 1. The step support structure 2 is designed to be larger at the bottom and smaller at the top, so that the larger step part of the upper cup overlaps the smaller step upper part of the lower cup, and the cups are less likely to be squeezed together, which is more conducive to cup separation.
[0032] Therefore, the cups in this embodiment, by adding the exhaust groove 4 on the step support structure 2, can help the air pressure inside and outside the cups to quickly achieve air pressure balance when the cups are stacked, so that the cups can be well separated even when the gap between the side walls of the cups is relatively small; at the same time, the side walls of the step support structure 2 are designed to be a tapered structure with a larger bottom and a smaller top, which can make the cups less likely to be squeezed together, is more conducive to smooth cup separation, and more effectively ensures the use of the cups on the production line, thereby improving production efficiency.
[0033] In a specific implementation, the number of the exhaust grooves 4 can be adjusted as needed, and the entire cup can be used for any food cup.
[0034] The entire cup is integrally formed. To facilitate processing, the exhaust groove 4 is formed by the bottom of the step support structure 2 being recessed from outside to inside, specifically, by the step bottom surface 22 of the step support structure 2 being recessed upward.
[0035] The shape of the exhaust groove 4 is preferably a rectangular structure. The wider, taller and deeper the rectangular structure is, the more conducive it is to faster balance of high and low air pressures inside and outside. Considering the overall aesthetics and molding limitations, the width of the exhaust groove 4 along the circumference of the cup body 3 is 6-7mm, the height of the exhaust groove 4 along the height direction of the cup body 3 is 1.5-2mm, and the depth of the exhaust groove 4 along the radial direction of the cup body 3 is 1.5-2mm.
[0036] The groove walls on both sides of the exhaust groove 4 (ie, the groove walls on both sides along the circumference of the cup body 3) are symmetrical arc-shaped wall surfaces 41 to prevent the formation of structural dead angles that are not conducive to the aseptic process.
[0037] Reference Figure 1 The step support structure 2 includes a step side wall 21 and a step bottom surface 22 which are connected in a bent manner. The top of the step side wall 21 is connected to the cup edge 1, and the bottom of the step bottom surface 22 is connected to the top opening of the cup body 3. The exhaust groove 4 is provided on the step bottom surface 22. The step bottom surface 22 preferably adopts a curved surface structure.
[0038] Furthermore, the cup body 3 includes a cup body 31 with openings at both ends and a cup bottom 32 connected to the bottom of the cup body 31 .
[0039] Generally, the center of the cup bottom 32 is concave to form a central groove 323 to improve the pressure resistance of the cup bottom 32 and improve the structural stability of the cup. Figure 6 The bottom of the cup body 31 is connected to the cup bottom 32 via an arc structure 33 .
[0040] In summary, when the cups are stacked, the step bottom surface 22 of the step support structure 2 of the upper cup overlaps the cup edge 1 of the lower cup. When the exhaust groove 4 is not provided, the step bottom surface 22 of the entire step support structure 2 of the upper cup contacts the cup edge 1 of the lower cup. The outer wall 321 of the cup bottom of the upper cup and the inner wall 322 of the cup bottom of the lower cup cannot quickly form air convection with the outside world, and thus the air pressure balance cannot be formed, causing the upper and lower cups to be locked together. When the exhaust groove 4 is added, at the position of the exhaust groove 4, the step bottom surface 22 does not contact the cup edge 1, and there is a gap. In this way, the air flow inside and outside the cup can be achieved through the exhaust groove 4, so that the internal and external air pressures can quickly reach a balance, and smooth cup separation can be achieved. At the same time, the step side wall 21 of the step support structure 2 is designed as a conical structure with a small top and a large bottom, which can make the cups less likely to be squeezed together, and is more conducive to smooth cup separation.
[0041] The above is only an illustrative embodiment of the utility model, and is not intended to limit the scope of the utility model. Any equivalent changes and modifications made by any technician in the field without departing from the concept and principle of the utility model should fall within the scope of protection of the utility model.
