[0018] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Specific implementation examples are given below.

[0020] Please see Figure 1 - Figure 6 This utility model provides a flat oval box with a threaded flip-top, including a bottle body 1. A connecting post 11 is fixedly connected to the top of the bottle body 1. A sleeve 2 is fitted onto the surface of the connecting post 11. A connecting plate 3 is fixedly connected to the top of the sleeve 2. A first airbag 31 is provided on the inner wall of the connecting plate 3. A compression plate 32 is provided at the bottom of the first airbag 31. An air tube 33 is fixedly connected to the inner side of the first airbag 31. A second airbag 34 is fixedly connected to the other end of the air tube 33. By setting the connecting post 11 fixedly connected to the top of the bottle body 1 and the sleeve 2 fitted onto the surface of the connecting post 11, the opening and closing operation of the flip-top is achieved by the threaded engagement between the connecting post 11 and the sleeve 2. The threaded connection structure has strong stability. By setting the first airbag 31 on the inner wall of the connecting plate 3 and the compression plate 32 at the bottom, when the sleeve 2 is fitted onto the connecting post 11... When tightened, the compression plate 32 will compress the first airbag 31 as the sleeve 2 is pressed down, causing the first airbag 31 to expand and tightly fit the gap at the opening of the box, effectively blocking the air from the outer wall from entering the bottle 1 and greatly improving the sealing performance of the box. By setting an air pipe 33 fixedly connected to the inner side of the first airbag 31 and a second airbag 34 fixedly connected to the other end of the air pipe 33, when the first airbag 31 is compressed and generates air pressure, the air pressure will be transmitted to the second airbag 34 through the air pipe 33, causing the second airbag 34 to expand below the opening inside the bottle 1 and form a sealing structure. By setting the combination structure of the connecting plate 3, the first airbag 31 and the compression plate 32, when the box is closed, the cooperation between the first airbag 31 and the compression plate 32 can not only achieve sealing, but also reduce the external impact on the box through the elastic buffering effect of the airbag.

[0021] In the above solution, the bottle body 1 is made of plastic, and the sleeve 2 has a threaded connection to the connecting post 11. By using a plastic bottle body 1, it is lightweight, not easily broken, has good impact resistance, is easy to carry and transport, and has low cost. The production process is simple, and it can be made into various shapes and colors. Common materials include PET and PP, which are used for packaging beverages, juices, sauces, cosmetics, etc. The flat oval bottle design takes into account functionality, aesthetics, and user experience. By setting the threaded connection structure between the sleeve 2 and the connecting post 11, and with the plastic material, a tight connection can be formed when the threads are engaged, providing stable sealing and the ability to be repeatedly opened and closed, extending the service life of the box and expanding its application range.

[0022] Example 1: Please see Figure 1 - Figure 2 This utility model provides a technical solution: Specifically, a connecting block 4 is connected to the surface hinge of the sleeve 2, and a bonding plate 41 is connected to the side hinge of the connecting block 4. A first buckle 42 is fixedly connected to the surface of the bonding plate 41, and a cover plate 43 is fixedly connected to the bottom of the bonding plate 41. By setting the connecting block 4 connected to the surface hinge of the sleeve 2 and the bonding plate 41 connected to the side hinge of the connecting block 4, when the box is in the open state, the bonding plate 41 can rotate freely around the hinge of the connecting block 4, driving the cover plate 43 fixedly connected to the bottom to move synchronously. This prevents the cover plate 43 from completely separating from the box during the opening and closing process and thus being lost. At the same time, the flexibility of the hinge connection allows the cover plate 43 to be kept at an angle that is easy to operate, which is convenient. To enhance user convenience, the first buckle 42, which is fixedly connected to the surface of the adhesive plate 41, can engage with the first slot 22 of the bottle 1 when the box is closed. This further enhances the stability of the closed box and prevents the contents of the bottle 1 from spilling out due to accidental opening of the cover 43. This is especially suitable for safety protection during carrying. By setting the hinge connection structure of the connecting block 4, the adhesive plate 41, and the first buckle 42 on the surface of the adhesive plate 41, when the user opens or closes the box, they only need to unfasten the first buckle 42, then pull the adhesive plate 41 and the cover 43 through the hinge, and then rotate the sleeve 2 to open the box. The operation steps are smooth and effortless.

[0023] It should be noted that the first slot 22 and the first buckle 42 are adapted to each other. By setting the first buckle 42, which is fixedly connected to the surface of the fitting plate 41, and the first slot 22 on the sleeve 2, when the box is closed, the first buckle 42 can accurately engage with the first slot 22, forming a clearly positioned fastening structure. This allows the user to complete the fastening operation without repeated adjustments. At the same time, the precise fit structure can improve the tightness of the engagement between the buckle and the slot, further enhancing the fixing effect after the box is closed and preventing the buckle from falling off due to vibration during carrying. The adapter structure of 2 produces a clear snapping sound when the buckle engages or disengages from the slot during the opening and closing of the box, providing clear operational feedback to the user. This allows the user to intuitively judge whether the box is fully closed or open, avoiding poor sealing due to loose fasteners. When the box is subjected to external pressure or impact, the first buckle 42 and the first slot 22 can jointly bear part of the force, reducing the stress load at the threaded connection between the sleeve 2 and the connecting column 11. This prevents the threads from deforming or stripping due to long-term stress concentration, extends the service life of the threaded connection structure, and reduces the frequency of component maintenance or replacement.

[0024] Example 2: Please see Figure 2 - Figure 6 This utility model provides a technical solution: Specifically, the surface of the sleeve 2 is provided with a first groove 22, and handles 21 are fixedly connected to both sides of the sleeve 2. A protrusion 23 is fixedly connected to the surface of the sleeve 2. By providing the first groove 22 on the surface of the sleeve 2, a locking space is provided for the first buckle 42 fixedly connected to the surface of the bonding plate 41. By providing the handles 21 fixedly connected to both sides of the sleeve 2, when the user rotates the sleeve 2 to open or close the box, he / she can hold the handles 21 with both hands to apply force, which can more easily control the rotation force and avoid hand slippage leading to operation errors. By providing the protrusion 23 fixedly connected to the surface of the sleeve 2, the protrusion 23 can increase the friction between the hand and the surface of the sleeve 2. When the user holds the sleeve 2 directly without using the handles 21 and rotates it, it can effectively prevent hand slippage and ensure smooth rotation operation. At the same time, the protrusion 23 can also play a certain structural reinforcement role on the surface of the sleeve 2, reducing the probability of deformation of the sleeve 2 during long-term use and extending the service life of the sleeve 2.

[0025] Furthermore, the connecting plate 3 has a round hole 5 inside, and a second slot 51 is fixedly connected to the top of the connecting plate 3. A second buckle 52 is fixedly connected to the surface of the cover plate 43. By setting the second slot 51 fixedly connected to the top of the connecting plate 3 and the second buckle 52 fixedly connected to the surface of the cover plate 43, when the cover plate 43 is closed on the connecting plate 3, the second buckle 52 can be accurately engaged in the second slot 51 to form a secondary fastening and fixing structure. With the fastening of the first buckle 42 and the first slot 22, the double buckle positioning can further enhance the stability of the box after it is closed, prevent the cover plate 43 from shifting due to the loosening of a single buckle, effectively prevent the contents of the bottle 1 from getting damp or spilling, and improve storage safety.

[0026] It should be added that the second slot 51 is adapted to the second buckle 52. By setting the second slot 51 and the second buckle 52 to be adapted, the precise cooperation between the two during the fastening process can make the cover plate 43 fit tightly against the top of the connecting plate 3, reducing the gap between the cover plate 43 and the connecting plate 3.

[0027] Furthermore, a sealing ring is provided on the surface of the second buckle 52. By providing a sealing ring on the surface of the second buckle 52, when the second buckle 52 and the second slot 51 are fitted together, the sealing ring will be squeezed and filled in the mating gap between the buckle and the slot, forming a double sealing structure. At the same time, the elastic properties of the sealing ring can play a buffering role when the second buckle 52 and the second slot 51 are fitted together. The sealing ring can fill the mating gap caused by thermal expansion and contraction of the material through elastic adjustment, avoiding sealing failure caused by temperature changes.

[0028] Working principle: When closing the box, the cover plate 43 is first rotated to the top of the connecting plate 3 via the hinge structure of the connecting block 4 and the bonding plate 41, so that the second buckle 52 on the surface of the cover plate 43 aligns with the second slot 51 of the connecting plate 3 and is fastened. The sealing ring on the surface of the second buckle 52 is compressed to fill the gap, forming a preliminary seal and fixation. Then, the first buckle 42 on the surface of the bonding plate 41 is fastened, so that it fits and locks into the first slot 22 of the sleeve 2, completing the double buckle positioning. Then, the sleeve 2 is rotated on both sides. The handle 21 or the surface of the sleeve 2 with the protrusion 23 is held directly. The sleeve 2 is threaded with the connecting post 11 at the top of the bottle body 1, so that the sleeve 2 moves down along the connecting post 11, which drives the connecting plate 3 to press down synchronously. The extrusion plate 32 on the inner wall of the connecting plate 3 presses down on the first airbag 31. After the first airbag 31 expands, it fits tightly against the opening gap of the box body. At the same time, the air pressure in the first airbag 31 is transmitted to the second airbag 34 through the air tube 33. The second airbag 34 expands below the opening inside the bottle body 1 to form a secondary seal.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
