Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of beverage serving cups, specifically referring to a sealed and reinforced beverage serving cup. Background Technology
[0002] In everyday beverage consumption, beverage cups are extremely common utensils. Traditional beverage cups primarily rely on threaded or snap-lock mechanisms for sealing.
[0003] When using a single thread seal, the fit of the thread, wear, and the characteristics of the beverage itself can all lead to unstable sealing performance. During daily carrying, if the cup is shaken or bumped, a single thread seal is prone to gaps, causing the beverage to leak, which not only soils personal belongings but may also result in waste. While snap-on seals may perform well initially, after frequent use, the snaps are prone to deformation and breakage, leading to seal failure. Utility Model Content
[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a sealed beverage container that effectively solves the problem of poor sealing effect of existing containers.
[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: A sealed and reinforced beverage cup includes a cup body and a cup lid. The outer wall of the cup body near the upper end is provided with an external thread layer, and the center of the thickness of the side wall is recessed downward along the upper end of the cup body to form a connecting cavity. The inner wall of the connecting cavity is provided with an internal thread layer, and the cup lid is threadedly connected to both the internal thread layer and the external thread layer.
[0006] The top of the connecting cavity is sealed with an annular sealing top plate. Several limiting support rods are fixed on the lower surface of the sealing top plate. The bottom of the limiting support rods is slidably disposed at the bottom of the connecting cavity. A spring is fitted over the limiting support rod and fixed to the lower surface of the sealing top plate and the bottom of the connecting cavity.
[0007] Preferably, the top longitudinal section of the sealing top plate and the top of the connecting cavity is an isosceles trapezoid, and the top surface of the sealing top plate is flush with the top surface of the connecting cavity, and the two abut against each other to prevent the sealing top plate from moving out of the connecting cavity.
[0008] Preferably, the cup lid is provided with an external mating thread and an internal mating thread from the outside to the inside, the external mating thread engaging with the external thread layer, and the internal mating thread engaging with the internal thread layer.
[0009] Preferably, the lower part of the cup lid that overlaps with the cup body is configured as a double-layer structure including an outer layer and an inner layer, wherein the outer mating thread is located on the inner side of the outer layer and the inner mating thread is located on the inner side of the inner layer.
[0010] Preferably, the sealing top plate is made of rubber or silicone material.
[0011] Preferably, a handle is fixed to the upper part of the cup lid, and an anti-slip pad is fixed to the bottom of the cup body.
[0012] Preferably, the top of the cup lid has a threaded hole, and a sealing plug is partially exposed outside the cup lid and threaded inside the threaded hole.
[0013] The beneficial effects achieved by adopting the above-described structure are as follows:
[0014] 1. This application innovatively sets up double-layer threads at the lid and mouth of the cup. Compared with the traditional single-thread seal, it greatly expands the sealing contact area. When the lid is tightened, the inner and outer double-layer threads are tightly engaged, which significantly enhances the sealing effect. Whether it is placed in daily life or when the cup is tilted or inverted during travel, it can effectively prevent liquid leakage and provide a solid guarantee for the safe storage and carrying of beverages.
[0015] 2. A connecting cavity is set inside the cup mouth wall, and a sealing top plate is installed on its top. During the tightening of the cup lid, the sealing top plate is squeezed, causing the spring to contract. When the cup lid is removed, the spring rebounds, causing the sealing top plate to quickly seal the top of the connecting cavity tightly and fit closely with the cup mouth, preventing foreign objects from falling into the connecting cavity.
[0016] 3. The specially designed threaded hole and matching sealing plug on the lid greatly facilitate the insertion and use of the straw. When consumers need to use a straw to drink, they only need to unscrew the sealing plug and insert the straw to enjoy it easily; when not using a straw, tighten the sealing plug, which not only meets the diverse needs of different users for drinking methods, but also ensures the airtightness.

The utility model will be further described in detail below with reference to the accompanying drawings.
[0026] like Figure 1-6 As shown, the present invention proposes a sealed and reinforced beverage container, comprising a cup body 1 and a cup lid 2. The outer wall of the cup body 1 is provided with an external thread layer 3 near the upper end, and a connecting cavity 14 is formed by a downward indentation at the center of the thickness of the side wall along the upper end of the cup body 1. The inner wall of the connecting cavity 14 is provided with an internal thread layer 4. The cup lid 2 is threadedly connected to the internal thread layer 4 and the external thread layer 3. The cup lid 2 is provided with an external mating thread 8 and an internal mating thread 9 from the outside to the inside. The external mating thread 8 engages with the external thread layer 3, and the internal mating thread 9 engages with the internal thread layer 4. The lower part of the cup lid 2 that overlaps with the cup body 1 is configured as a double-layer structure including an outer layer and an inner layer. The external mating thread 8 is located on the inner side of the outer layer, and the internal mating thread is located on the inner side of the inner layer.
[0027] like Figure 2 , 3As shown, the top of the connecting cavity 14 is sealed with an annular sealing top plate 5. The sealing top plate 5 is made of rubber or silicone material and is pressed between the outer and inner layers to achieve a tight seal. The longitudinal section of the sealing top plate 5 and the top of the connecting cavity 14 is an isosceles trapezoid. The top surface of the sealing top plate 5 is flush with the top of the connecting cavity 14. The two abut against each other to prevent the sealing top plate 5 from moving out of the connecting cavity 14. Several limiting support rods 6 are fixed on the lower surface of the sealing top plate 5. The bottom of the limiting support rods 6 is slidably located at the bottom of the connecting cavity 14. The limiting support rods 6 are fitted with springs 7 that are fixed to the lower surface of the sealing top plate 5 and the bottom of the connecting cavity 14.
[0028] like Figure 5 , 6 As shown, a handle 10 is fixed to the upper part of the cup lid 2 for easy use, and an anti-slip pad 11 is fixed to the bottom of the cup body 1 to increase friction and ensure stability. A threaded hole 12 is opened at the top of the cup lid 2, and a sealing plug 13 is partially exposed outside the cup lid 2 through the threaded connection inside the threaded hole 12. The sealing plug 13 is unscrewed to facilitate the insertion of a straw for use.
[0029] In actual use, when you need to drink a beverage, hold the cup body 1 and unscrew the cup lid 2 counterclockwise. At this time, the sealing top plate 5 moves up quickly under the upward elastic force of the spring 7, sealing the top of the connecting cavity 14 tightly and fitting the cup mouth tightly. After drinking, tighten the cup lid 2 clockwise, and press the sealing top plate 5 down into the connecting cavity 14. The outer mating thread 8 engages with the outer thread layer 3, and the inner mating thread 9 engages with the inner thread layer 4. The double threads maintain the sealing state, ensuring that the cup is in a sealed state, which is convenient for storage and carrying.
[0030] If you choose to use a straw to drink, first unscrew the sealing plug 13 on the cup lid 2 with your fingers, and insert the straw into the cup body 1 along the threaded hole 12. During use, the cup lid 2 should always be tightened on the cup mouth. After use, take out the straw and tighten the sealing plug 13 clockwise to restore the complete sealing performance of the cup lid 2.
[0031] Magnets can also be embedded in the top of the sealing top plate 5 and the connecting cavity 14 to enhance the instantaneous sealing response speed.
[0032] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
