Abstract
Description
Technical Field
[0001] This utility model relates to the field of paper cup structure technology, and in particular to a paper cup structure with a sealing cap to prevent spillage. Background Technology
[0002] Paper cups, as disposable beverage containers commonly used in daily life and business activities, are favored for their convenience and hygiene, and are widely used for serving various beverages such as coffee, tea, and juice. However, existing ordinary paper cups have some obvious defects in actual use, especially in terms of spill prevention, which causes a lot of trouble for users.
[0003] Ordinary paper cups typically rely on only a single bottom to contact the surface they are placed on. The bottom area is limited, resulting in a small contact area between the paper cup and the surface when placed. This makes it difficult to effectively distribute the weight of the paper cup itself and the liquid it contains. When the cup is shaken on the table, it is very easy for it to lose its balance and tip over. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a paper cup structure with a sealing cap to prevent spillage.
[0005] This utility model is achieved by the following technical solution: a paper cup structure with a sealing cap to prevent spillage, including a support mechanism, a main body mechanism on the top of the support mechanism, and protective mechanisms on both sides of the main body mechanism;
[0006] The support mechanism includes a base plate, a connecting column fixedly connected to the top of the base plate, and a top plate fixedly connected to the top of the connecting column.
[0007] As a further improvement to the above scheme, the bottom plate and the top plate are symmetrically distributed through connecting columns.
[0008] Through the above technical solution, the supporting mechanism provides stable support for the entire paper cup. When placing the paper cup, the bottom plate can increase the contact area with the placement surface, dispersing the weight of the paper cup and the liquid inside, making the paper cup more stable and less likely to tip over. This effectively reduces the risk of tipping over due to shaking or external impact, and prevents beverages from spilling.
[0009] As a further improvement to the above solution, the main structure includes a cup body, a connecting ring is fixedly connected to the top of the cup body, and a cup lid is fixedly connected to the top of the connecting ring.
[0010] As a further improvement to the above solution, the top of the cup lid is provided with a vent hole, and a cup opening is provided on one side of the vent hole, with the cup opening located at the top of the cup lid.
[0011] Through the above technical solution, the main structure is designed so that the cup body is fixedly connected to the cup lid via a connecting ring, thereby ensuring a good seal between the cup lid and the cup body. The connecting ring also strengthens the connection, making the cup lid less likely to loosen after being fastened, effectively preventing beverage spillage. Even when the paper cup is shaken to a certain extent, it can maintain a good seal and reduce the possibility of beverage leakage.
[0012] As a further improvement to the above solution, the protective mechanism includes a first protective ring, a first fixed shaft is fixedly connected to the bottom of the first protective ring, a connecting plate is sleeved on the surface of the first fixed shaft, a second fixed shaft is sleeved on the side of the connecting plate away from the first fixed shaft, and a second protective ring is fixedly connected to the bottom of the second fixed shaft.
[0013] As a further improvement to the above solution, both the first protective ring and the second protective ring are fitted onto the surface of the cup body, with the second protective ring located at the bottom of the first protective ring.
[0014] Through the above technical solution, by setting up a protective mechanism, and by setting up a first protective ring and a second protective ring, it is possible to prevent beverages from spilling. When the paper cup is accidentally tilted or subjected to external impact, the first protective ring and the second protective ring can block the spilled beverages and prevent them from flowing directly onto the table.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] This invention provides a stable support for the paper cup through its supporting mechanism. When the paper cup is placed, the base plate increases the contact area with the surface, distributing the weight of the paper cup and its contents, making the cup more stable and less prone to tipping. This effectively reduces the risk of tipping due to shaking or external impact, preventing spills. The main structure secures the cup body to the lid via a connecting ring, ensuring a good seal between the lid and body. The connecting ring also strengthens the connection, preventing the lid from loosening after locking, effectively preventing spills. Even when the paper cup is shaken to some extent, it maintains a good seal, reducing the possibility of leakage. The protective mechanism, with its first and second protective rings, further prevents spills. When the paper cup is accidentally tilted or impacted, the first and second protective rings block any spilled beverage, preventing it from flowing directly onto the table.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example
[0024] Please combine Figure 1-4 The paper cup structure with a sealed lid to prevent spillage in this embodiment includes a support mechanism 1, a main body mechanism 2 on the top of the support mechanism 1, and protective mechanisms 3 on both sides of the main body mechanism 2.
[0025] The support mechanism 1 includes a base plate 101, a connecting column 102 fixedly connected to the top of the base plate 101, and a top plate 103 fixedly connected to the top of the connecting column 102.
[0026] The base plate 101 and the top plate 103 are symmetrically distributed through the connecting column 102.
[0027] The main body 2 includes a cup body 201, a connecting ring 202 fixedly connected to the top of the cup body 201, and a cup lid 203 fixedly connected to the top of the connecting ring 202.
[0028] The top of the cup lid 203 has a vent hole 204, and a cup opening is provided on one side of the vent hole 204. The cup opening is located on the top of the cup lid 203.
[0029] The protective mechanism 3 includes a first protective ring 301, a first fixed shaft is fixedly connected to the bottom of the first protective ring 301, a connecting plate 302 is sleeved on the surface of the first fixed shaft, a second fixed shaft is sleeved on the side of the connecting plate 302 away from the first fixed shaft, and a second protective ring 303 is fixedly connected to the bottom of the second fixed shaft.
[0030] Both the first protective ring 301 and the second protective ring 303 are sleeved on the surface of the cup body 201, with the second protective ring 303 located at the bottom of the first protective ring 301.
[0031] The implementation principle of this utility model is as follows: When the beverage is poured into the cup body 201, the cup body 201 and the cup lid 203 are tightly connected by the connecting ring 202. At this time, the cup lid 203 is in a sealed state to prevent the beverage from spilling during the pouring process. When the user is ready to drink the beverage, he drinks through the opening on the cup lid 203. During the drinking process, air enters the cup body 201 through the vent 204 to balance the air pressure inside and outside the cup, so that the beverage can flow out smoothly and is convenient for the user to drink. If the paper cup is accidentally tilted or slightly shaken during use, the first protective ring 301 and the second protective ring 303 will block the overflowing beverage, preventing it from spilling over a large area and protecting the table and the user's clothes from being soiled.
[0032] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
