Furthermore, some dental floss boxes are difficult to repair, hindering production, assembly, and maintenance. Therefore, there is an urgent need for a quick-assembly and disassembly dental floss box that is easy to open and close, has a novel appearance, a stable structure, and is easy to repair and assemble, to solve the problems of existing technology. Utility Model Content

[0003] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a quick-release dental floss box.

[0004] To achieve the above objectives, the present invention provides a quick-release dental floss box, comprising a lower box body and an upper box body rotatably mounted on the lower box body. The lower box body forms a first receiving cavity for receiving dental floss from the outside. The upper box body rotates and opens relative to the lower box body to expose or close the first receiving cavity.

[0005] The lower compartment and the rotating upper compartment structure provide a convenient opening and closing mechanism for the dental floss box. Users can easily open the upper compartment to access the floss, while the upper compartment effectively protects the floss from contamination when closed, maintaining its cleanliness and hygiene. This rotating opening and closing design is simple to operate, convenient for frequent daily use, and its robust structure ensures the lifespan of the dental floss box, enhancing the user experience.

[0006] Furthermore, the upper box body is a cartoon shape that matches the outline of the lower box body, and the cartoon shape is either a cartoon dog shape or a cartoon cat shape.

[0007] The upper box is designed in a cartoon shape that matches the outline of the lower box, such as a cartoon dog or a cartoon cat, greatly enhancing the floss box's fun and appeal. This unique design allows the floss box to stand out among many daily necessities, especially appealing to children and young consumers. It is not only easy for users to identify but can also be displayed as a decorative item, increasing the product's added value and market competitiveness.

[0008] Furthermore, the cross-section of the lower box body perpendicular to its height direction is elliptical.

[0009] The lower compartment has an elliptical cross-section perpendicular to its height, which is ergonomically designed to fit the hand better, making it easier for users to pick up and operate. Compared to other shapes, the elliptical shape provides better stability when placed, making it less likely to roll and fall, reducing the chance of damage to the dental floss box or floss scattering due to accidental slippage, thus improving safety and convenience.

[0010] Furthermore, the upper box body is provided with a first snap-fit ​​component, and the lower box body is provided with a second snap-fit ​​component, wherein the first snap-fit ​​component is used to snap-fit ​​with the second snap-fit ​​component.

[0018] Furthermore, the fixed shaft has two limiting sections disposed on the lower housing and a rotating section located between the two limiting sections, the diameter of the limiting sections being larger than the diameter of the rotating section; the rotating part is located between the two limiting sections and is rotatably disposed on the rotating section.

[0019] The design of the fixed shaft's limiting section and rotating section, using the diameter difference to limit the rotating part, prevents axial movement of the rotating part during rotation, ensuring the stability and reliability of the upper box's rotation. This reasonable structural design effectively extends the service life of the rotating connection parts of the dental floss box and reduces malfunctions caused by loose components.

[0020] Furthermore, the lower box body is provided with a fitting surface that fits with the upper box body, and a first annular guide portion is formed by protruding outward from the fitting surface along the height direction of the lower box body. The upper box body is provided with a second annular guide portion that cooperates with the first annular guide portion.

[0021] The first annular guide portion of the lower box engages with the second annular guide portion of the upper box, acting as a guide during the opening and closing of the upper box. This ensures a more precise relative position between the upper and lower boxes, guaranteeing a tight seal when the dental floss box is closed. Simultaneously, the guide structure reduces friction between the upper and lower boxes, resulting in smoother opening and closing operations and an improved user experience.

[0022] Furthermore, the first annular guide portion has a guide arc portion and a guide slope portion that are transitionally connected, and the guide slope portion is transitionally connected to the mating surface. The second annular guide portion has a slope portion that mates with the guide arc portion and the guide slope portion.

[0023] The guide arc and guide slope of the first annular guide part cooperate with the slope of the second annular guide part to further optimize the guiding effect between the upper and lower boxes. This structural design makes it easier for the upper box to be aligned during opening and closing, reducing the difficulty of operation, while enhancing the sealing and stability of the dental floss box when closed, effectively protecting the dental floss inside.
