[0023] Reference Figure 1-2 The image shown is a preferred embodiment of the present invention.

[0024] A box for holding playing cards includes a lower shell 100 and an upper shell 200 that is inserted into or separated from the upper shell. The lower shell 100 has a lower outer peripheral wall arranged around its outer periphery. The lower shell 100 surrounds a lower cavity that forms a top opening and holds the playing cards. An insertion section 101 is formed on the upper part of the lower outer peripheral wall, and an outer section 102 is formed on the lower part of the lower outer peripheral wall. The insertion section 101 is connected to the outer section 102.

[0025] The upper shell 200 surrounds the upper cavity forming the bottom opening. The outer periphery of the upper shell 200 has an annularly arranged upper outer peripheral wall 201. The insertion section 101 is inserted into the upper cavity, abuts against the upper outer peripheral wall 201, and is snapped together with the upper outer peripheral wall 201. The external section 102 is exposed below the upper shell 200, and the upper shell 200 closes the top opening of the lower cavity.

[0026] The aforementioned playing card box achieves a secure and reliable mechanical interlock between the upper shell 200 and the lower shell 100 by inserting the plug section 101 of the lower shell 100 into the upper cavity of the upper shell 200 and forming a snap-fit ​​connection, thus preventing accidental loosening. At the same time, the abutment between the plug section 101 and the upper outer peripheral wall 201 forms a sealing barrier, which also improves the effectiveness of the playing card box in storing playing cards.

[0027] In this embodiment, the top of the outer segment 102 has an upwardly arranged positioning step 103, which is arranged around the circumference of the lower shell 100. The bottom of the upper outer peripheral wall 201 abuts against the positioning step 103. The surrounding positioning step 103 provides a precise axial positioning reference and stable radial support for the assembly of the upper shell 200 and the lower shell 100, ensuring that the snap-fit ​​connection can be accurately aligned and engaged. At the same time, by increasing the contact area, the impact force is dispersed, improving the convenience of assembly and the overall durability.

[0028] In this embodiment, the plug segment 101 is provided with a plurality of notches 104, which extend along the height direction of the plug segment 101 and penetrate the plug segment 101 laterally; the plug segment 101 has an elastic wall 105, which is located between adjacent notches 104, and the elastic wall 105 is snapped to the upper outer peripheral wall 201.

[0029] The bottom of the plug section 101 is semi-circular, which reduces burrs formed during the production of the playing card box. Furthermore, the notch groove 104 in the plug section 101 forms an elastic independent wall section, which reduces the assembly force required for the snap-fit ​​connection, making the opening and closing operation easier and smoother. At the same time, the deformation capacity of the elastic wall 105 ensures that the snap-fit ​​connection can fully engage and disengage, avoiding wear or breakage of the playing card box during repeated use, and improving the durability and handling feel of the playing card box.

[0030] In this embodiment, the plug-in section 101 has two elastic walls 105, which are arranged facing each other. The two facing elastic walls 105 generate symmetrical and balanced clamping and rebound forces when the snap-fit ​​connection is made, ensuring that the upper shell 200 and the lower shell 100 are subjected to uniform force and accurately aligned when connected. This can prevent skewing, shaking or abnormal noise caused by unilateral stress and improve the stability of the connection.

[0031] In this embodiment, the elastic wall 105 is provided with a locking block 106, and the upper outer peripheral wall 201 is provided with a locking groove 202. The locking block 106 is embedded in the locking groove 202 so that the elastic wall 105 and the upper outer peripheral wall 201 are snapped together. The locking block 106 and the locking groove 202 cooperate with each other to realize the front mechanical locking between the upper shell 200 and the lower shell 100. This not only enhances the tensile strength of the connection and the reliability of preventing accidental disengagement, but also provides the user with a clear "click" feeling when the locking block 106 is embedded in the locking groove 202, providing a definite feedback of successful connection. At the same time, it disperses stress over a larger contact surface, improving the durability of long-term use.

[0032] In this embodiment, the elastic wall 105 is provided with a limiting structure, which limits the insertion depth of the plug segment 101 into the upper cavity. The limiting structure is located below the locking block 106. The bottom of the limiting structure is semi-circular, which can reduce the rough edges formed during the production of the playing card box. During the installation of the playing cards, the limiting structure located below the locking block 106 can provide a precise physical stop point for the insertion depth of the plug segment 101, ensuring that the locking block 106 can be accurately aligned with the slot 202. This can prevent excessive buckling stress, structural deformation or damage caused by excessive insertion, as well as connection failure caused by insufficient insertion.

[0033] In this embodiment, the limiting structure includes a limiting block 107 disposed on the elastic wall 105. The bottom of the upper outer peripheral wall 201 is recessed upward to form a limiting groove with a bottom opening. The limiting block 107 is embedded in the limiting groove and extends to the outside of the upper shell 200. The limiting block 107 supports the upper shell 200 from bottom to top.

[0034] The limiting block 107 is embedded in the limiting groove and extends to the outside of the upper shell 200, ensuring that the weight of the upper shell 200 and the downward impact force are directly transmitted to the robust lower shell 100 outer section 102 for bearing, reducing the load on the elastic wall 105 and the snap-fit ​​connection structure, preventing the playing card box from fatigue damage due to long-term stress, and enhancing the strength, stability and durability of the overall structure.

[0035] In this embodiment, the top of the limiting block 107 has an arc-shaped support surface, and the top of the limiting groove has an arc-shaped top surface, which presses against the support surface. The contact surface between the limiting block 107 and the limiting groove is an arc surface, which transforms the traditional point contact or line contact into a more optimized surface contact. This can disperse local compressive stress and avoid wear or pressure damage caused by stress concentration. At the same time, the arc surface structure allows for slight adaptive adjustments when under force, making the support more stable and smooth, and improving the reliability and durability of long-term use.

[0036] In this embodiment, the upper shell 200 is made of transparent material, and the bottom of the lower shell 100 has a bottom plate 108 with a perforated hole 109 that penetrates through it. The perforated hole is circular, including elliptical, and its circular shape reduces rough edges on the playing card box during production. By making the upper shell 200 transparent and using the bottom plate 108 with the perforated hole 109, users can visually inspect the style and condition of the playing cards inside the box without opening the lid, improving ease of use. At the same time, the bottom perforated hole 109 allows fingers to easily insert and push the cards upwards, solving the problem of playing cards being difficult to remove due to tight fit, and also has multiple practical functions such as reducing weight, saving materials, and enhancing ventilation and moisture protection.

[0037] In this embodiment, a plurality of protrusions 110 are provided on the bottom plate 108. The plurality of protrusions 110 are arranged in an array and formed in the lower cavity. The top of the protrusion 110 is recessed downward to form a recessed groove. The outer periphery of the recessed groove is formed with an annular edge that abuts against a playing card.

[0038] An array of protrusions 110 with recessed grooves is provided on the bottom plate 108, so that its annular edge supports the playing cards with the minimum contact area, reducing the adsorption area between the playing cards and the bottom plate, and avoiding the difficulty of picking up the cards due to vacuum adsorption; at the same time, the array structure can evenly distribute the weight of the playing cards and external impact force, preventing the card surface from bending or being damaged by single-point force, thereby significantly improving the convenience of picking up the cards while better protecting the flatness and integrity of the playing cards.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
