Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of beverage serving cups, specifically referring to a multi-sealing-point beverage serving cup. Background Technology
[0002] In daily life, people widely use various cups to hold beverages. The sealing performance of these cups directly affects the user experience, especially in scenarios such as carrying or exercising, where good sealing performance is particularly important.
[0003] Most cup lids rely solely on a simple snap-fit between the cup body and the lid. The top of the cup opening has a horizontal flange, while the bottom of the lid is flat. The flange is pressed directly against the lid, and the bottom wall of the lid is brought into close contact with the flange plane to form a seal. However, the sealing effect is limited. Furthermore, the straw opening on the lid is often designed as a straight tube, making it easy for the cap to fall off and resulting in a poor seal. Utility Model Content
[0004] The technical problem this invention aims to solve is that traditional cup lids have a relatively simple sealing structure, making it difficult to effectively prevent liquid leakage. Furthermore, the straw opening on the cup lid often adopts a straight cylindrical design, making the cap easy to fall off and resulting in a poor seal.
[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: A multi-sealing-point beverage container includes a cup body, a cup lid is attached to the top of the cup body, a snap-fit is provided on the top of the cup body, a flange is provided on the outer side wall of the snap-fit, the bottom wall of the cup lid is pressed onto the flange, the flange is a right-angled trapezoidal structure, the bottom of the cup lid is matched with the flange, the bottom wall of the cup lid is pressed onto the flange to form a first seal, the inner side wall of the cup lid is provided with an inner protrusion, a sealing sleeve is fitted on the inner protrusion, and the top of the snap-fit adapts to the curved surface of the sealing sleeve to form a second seal.
[0006] Preferably, the top wall of the cup lid is provided with a straw opening, which has a hole-like structure that is wider at the top and narrower at the bottom. A matching cap is sealed inside the straw opening, and a connecting line is fixed between the top of the cap and the top wall of the cup lid.
[0007] Preferably, the outer edge of the inner protrusion is configured with a curved surface structure, and the sealing sleeve is configured to match the inner protrusion.
[0008] Preferably, a locking component is provided between the cup lid and the cup body. The locking component includes a hook and a buckle. A base is fixedly provided on the side wall of the cup lid. The top of the hook is rotatably mounted on the base via a shaft. A groove is provided on the bottom side wall of the hook. The buckle is located on the side wall of the cup body and is engaged in the groove. The buckle is a rectangular strip structure.
[0009] Preferably, the sealing sleeve is made of food-grade silicone.
[0010] Preferably, the hook and buckle are made of PP+glass fiber reinforced material.
[0011] The beneficial effects achieved by adopting the above-described structure are as follows:
[0012] 1. First seal: The bottom wall of the lid presses directly onto the flange of the cup body. The right-angled trapezoidal cross-section creates a tight fit between the inclined surfaces, providing a basic seal. The inclined sidewall generates a radial force when under pressure, enhancing the lateral fit of the lid. 2. Second seal: The silicone sealing sleeve inside the lid conforms to the top of the cup body's snap-fit mechanism. Even if the cup is tilted or shaken, the flexibility and elasticity of the sealing sleeve can compensate for displacement and maintain the seal. The inner protruding end uses a curved surface structure with a circular cross-section, ensuring the sealing sleeve is securely fitted and preventing it from falling off or shifting.
[0013] 2. The straw opening adopts a tapered structure that is wider at the top and narrower at the bottom, so that the cap forms an airtight plug to prevent liquid leakage.
[0014] 3. It adopts a mechanical locking structure of hook and ring. The hook can be rotated to lock, and the ring is rectangular and long, increasing the contact area to ensure that the cup lid is firmly locked and prevents accidental opening. Attached Figure Description
