A playing card packaging box

Abstract

A playing card packaging box includes a base box and a lid. At least one side wall of the base box has a rotatable movable plate, whose upper and lower edges are rotatably connected to the lid and the bottom of the base box, respectively. When the lid is opened, the movable plate flips, creating a card-removing opening in the side wall. The side wall containing the movable plate has a fixed wall, together forming a complete side wall. When the movable plate is closed, it abuts against the fixed wall, and rotation is limited by a limiting step on the fixed wall and a flange on the movable plate. The base box, movable plate, and lid are integrally formed and rotatably connected by flexible folds, allowing it to flatten when fully opened. Four positioning plates inside the base box restrict the sliding of the playing cards. A locking structure is provided between the lid and the base box, with the latch located in a groove in the lid, and reinforcing ribs on the inner side wall where it is located. The bottom edge of the lid covers the extended wall of the base box, leaving a notch in the movable plate area. This packaging box, through structural innovation, solves problems such as inconvenient card removal and insufficient structural linkage, improving card removal efficiency and durability.

Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, specifically to a playing card packaging box. Background Technology

[0002] Playing cards are widely used in various scenarios such as card games, entertainment, and gift-giving. With the increasing frequency of card game use, people have higher requirements for the durability, ease of access, and protection of playing card packaging boxes. Traditional playing card boxes are mostly made of cardboard, which has poor strength and wear resistance, and is easily deformed and damaged after repeated use, making them inconvenient to carry and use.

[0003] In the prior art, such as the "Playing Card Box" disclosed in application number 01246214.4 (authorization publication number CN2488868Y), the lid and base are injection molded in one piece, and a flexible connecting buckle and positioning plate design is used to improve durability and card protection. This playing card box adopts a horizontal structure, with a large opening when the lid is opened, and positioning plates are set at the four corners of the base to protect the four corners of the cards. However, it still has the following limitations:

[0004] 1. The card retrieval path is not optimized enough. Although there are gaps between the positioning plate and the box base on both sides, there is no hollow area that directly exposes the side of the card. Users still need to grope or tilt the card from the opening when retrieving it, which limits the efficiency of operation.

[0005] 2. The structural linkage is simple. The lid and the base of the box open and close by a flexible connecting buckle. After opening, the space for taking out the cards is still limited by the box wall, and no breakthrough optimization of the card taking path has been achieved.

[0006] In summary, the existing technology's "traditional cardboard box structure + partial plastic improvements" process chain suffers from poor durability, inconvenient card retrieval, and insufficient structural linkage. Although this solution attempts to improve through injection molding and positioning plate design, it fails to fundamentally resolve the contradiction of "obstructed card retrieval path," and structural innovation is urgently needed to improve card retrieval efficiency. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide a playing card packaging box that solves the problems of obstructed card retrieval path and limited structural space by using a linkage flip design between the lid and the side wall of the bottom box to realize the simultaneous unfolding of the side wall of the bottom box when the lid is opened, forming an open card retrieval opening.

[0008] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: the playing card packaging box includes a bottom box and a box lid. At least one side wall of the bottom box is provided with a rotatable movable plate. The lower edge of the movable plate is rotatably connected to the bottom of the bottom box, and the upper edge is rotatably connected to the box lid.

[0009] When the lid rotates from the closed state to the open state, it can cause the movable plate to flip outward, so that the side wall where the movable plate is located forms a hollow card-taking opening.

[0010] To make the side wall structure where the movable plate is located more complete, and to achieve rotational limitation when the movable plate is flipped to the closed state, preferably, the side wall where the movable plate is located also includes a fixed wall that is fixedly connected to the bottom box and cannot be flipped. The fixed wall is connected to both ends of the movable plate and together with the movable plate forms the complete structure of the side wall; when the movable plate is flipped to the closed state, it can abut against the fixed wall to form rotational limitation.

[0011] To further optimize the rotation limiting effect when the movable plate is flipped to the closed state and to ensure accurate and reliable limiting, preferably, a vertically extending limiting step is formed at the connection between the fixed wall and the movable plate, and a flange adapted to the limiting step is formed on the corresponding side of the movable plate.

[0012] When the movable plate is flipped upwards to the closed state, the flange abuts against the limiting step to limit the rotation of the movable plate.

[0013] To make the rotational connection between the bottom box, the movable plate, and the lid more reliable, and to ensure that all three can unfold to the same plane when the lid is fully open, preferably, the bottom box, the movable plate, and the lid adopt an integral molding structure and achieve rotational connection between them through a flexible connecting part;

[0014] With the lid fully open, the lid, movable plate, and bottom box can be unfolded to the same plane via flexible connecting parts.

[0015] To clarify the specific structure of the flexible connection part and to make the functions of the movable plate flipping outward relative to the bottom box and the lid flipping upward relative to the movable plate more reliable, preferably, the flexible connection part includes...

[0016] A first flexible crease is provided along the connection between the bottom box and the movable plate, the first flexible crease allowing the movable plate to be flipped outward relative to the bottom box;

[0017] A second flexible crease is provided along the connection between the movable plate and the lid, the second flexible crease allowing the lid to flip upward relative to the movable plate;

[0018] The first flexible crease and the second flexible crease are material thinning areas or pre-indentation structures.

[0019] To limit the sliding of the playing cards inside the box and ensure their stable position, preferably, the box is provided with four positioning plates to limit the sliding of the playing cards. The four positioning plates are respectively set on two opposite side walls of the box adjacent to the fixed wall, and are arranged in pairs to abut against the two sides of the playing cards.

[0020] In order to achieve locking between the bottom box and the lid, and to facilitate the opening and closing of the lid, preferably, a locking structure is provided between the bottom box and the lid. The locking structure includes a buckle plate on the lid that can be flipped, and the buckle plate has a locking hole.

[0021] A buckle is provided on the side of the bottom box and is adapted to the buckle hole; when the box lid is closed, the buckle plate flips and is fastened to the buckle through the buckle hole to lock the box lid and the bottom box.

[0022] In order to reasonably set the position of the buckle and avoid the buckle protruding and affecting the appearance and use of the packaging box, preferably, a groove that penetrates the top is formed on the outer side wall of the bottom box opposite to the movable plate, and the buckle is set in the groove.

[0023] To prevent the side wall where the buckle is located from being recessed inward due to the combined force of the buckle and to improve the structural strength of the side wall, preferably, a reinforcing rib is formed on the inner side of the side wall where the buckle is located. The reinforcing rib extends from the bottom wall of the bottom box along the height direction of the side wall to prevent the side wall from being recessed inward due to the combined force of the buckle.

[0024] To make the connection between the lid and the bottom box tighter and achieve a better sealing effect, preferably, the bottom of the lid is provided with a downwardly extending flange, the flange abuts against the upper edge of the side wall of the bottom box, and the flange has an avoidance notch in the area where the movable plate is located to avoid interfering with the rotation of the movable plate.

[0025] Compared with existing technologies, the advantages of this utility model are as follows: By providing a rotatable movable plate on at least one side wall of the bottom box, the lower edge of the movable plate is rotatably connected to the bottom of the bottom box, and the upper edge is rotatably connected to the lid. When the lid rotates from a closed state to an open state, it can drive the movable plate to rotate outward, forming a card-retrieving opening on the side wall where the movable plate is located. Since the movable plate is rotatably connected to the lid, the movable plate can rotate synchronously when the lid is opened. Therefore, a card-retrieving opening is formed on the side wall when the lid is opened, without additional operation. The card-retrieving path is directly exposed, and the user can conveniently retrieve cards from the card-retrieving opening, solving the problem of obstructed card-retrieving path in existing technologies and improving card-retrieving efficiency. Furthermore, since the formation of the card-retrieving opening is achieved through the linkage and rotation of the lid and the movable plate, no complex structure is required, so the structure is simple and has good linkage. At the same time, it avoids the problem of card-retrieving space being restricted by the box wall after opening, thus optimizing the card-retrieving path. Attached Figure Description

[0031] The present invention will be further described in detail with reference to the accompanying drawings and embodiments.

[0032] Figures 1-5 The figure shown is the preferred embodiment of the present invention. The specific implementation of the present invention will be described in detail below with reference to the accompanying drawings.

[0033] The playing card packaging box in this embodiment mainly includes a base box 1, a lid 2, a movable plate 3, a flexible connecting part 5, and a locking structure 7, etc. The specific structure and connection method of each component are described below:

[0034] Specific structure of the bottom box and lid: see reference Figures 1 to 4 As shown, the bottom box 1 is a rectangular box, and one side wall of the bottom box 1 is provided with a rotatable movable plate 3. The lower edge of the movable plate 3 is rotatably connected to the bottom of the bottom box 1, and the upper edge is rotatably connected to the lid 2. At both ends of the side wall where the movable plate 3 is located, there are fixed walls 3a that are fixedly connected to the bottom box 1 and cannot be rotatably rotated. The fixed walls 3a and the movable plate 3 together form the complete structure of this side wall. A vertically extending limiting step 3a1 is formed at the connection between the fixed wall 3a and the movable plate 3, and a flange 3b that adapts to the limiting step 3a1 is formed on the corresponding side of the movable plate 3. The bottom of the lid 2 is also provided with a downwardly extending flange 2a.

[0035] refer to Figure 3 and Figure 5 As shown, the interior of the base box 1 is provided with four positioning plates 6 to restrict the sliding of the playing cards. The four positioning plates 6 are respectively set on two opposite side walls of the base box 1 adjacent to the fixed wall 3a, and in pairs they abut against two opposite sides of the playing cards. On the outer wall of the side wall of the base box 1 opposite to the movable plate 3, a groove 1a penetrating the top is also formed. The buckle 7b is set in the groove 1a. A reinforcing rib 2b is formed on the inner side of the side wall where the buckle 7b is located. The reinforcing rib 2b extends from the bottom wall of the base box 1 along the height direction of the side wall and connects the bottom wall of the base box 1 and the side wall of the base box 1.

[0036] Specific connection structure between the bottom box and the lid: See reference Figure 2 and Figure 5As shown, the base box 1, the movable plate 3, and the lid 2 adopt an integrated injection molding structure and are rotatably connected to each other through a flexible connecting part 5. The flexible connecting part 5 includes a first flexible crease 5a and a second flexible crease 5b. The first flexible crease 5a is provided along the connection between the base box 1 and the movable plate 3, allowing the movable plate 3 to flip outward relative to the base box 1. The second flexible crease 5b is provided along the connection between the movable plate 3 and the lid 2, allowing the lid 2 to flip upward relative to the movable plate 3. The first flexible crease 5a and the second flexible crease 5b are material thinning areas or pre-indentation structures.

[0037] A locking mechanism 7 is also provided between the bottom box 1 and the lid 2, see reference. Figure 1 and Figure 3 As shown, the locking structure 7 includes a flip-up buckle plate 7a on the lid 2, with a latching hole 7a1 on the buckle plate 7a; and a latch 7b on the side of the bottom box 1 that matches the latching hole 7a1. When the lid 2 is closed, the buckle plate 7a flips and engages with the latch 7b through the latching hole 7a1 to lock the lid 2 and the bottom box 1. The flange 2a of the lid 2 abuts against the upper edge of the side wall of the bottom box. Alternatively, the flange 2a can be fitted onto the outer side of the upper edge of the side wall of the bottom box 1, and the flange 2a has an avoidance notch 2a1 in the area where the movable plate 3 is located to avoid interfering with the flipping of the movable plate 3.

[0038] The working principle of the playing card packaging box in this embodiment is as follows:

[0039] 1. Opening and card drawing process

[0040] When the lid 2 rotates from the closed to the open state, it causes the movable plate 3 to flip outward, creating a card-retrieving opening 4 on the side wall where the movable plate 3 is located. Through this exposed card-retrieving opening 4, playing cards can be quickly retrieved with a simple flick of the finger. Because the bottom box 1, the movable plate 3, and the lid 2 are integrally molded and are connected to each other by a flexible connecting part 5, when the lid 2 is fully open, the lid 2, the movable plate 3, and the bottom box 1 can unfold to the same plane through the flexible connecting part 5.

[0041] 2. Closing and locking process

[0042] When the movable plate 3 is flipped into the closed state, it abuts against the fixed wall 3a to form a rotation limit. Specifically, when the movable plate 3 is flipped upwards into the closed state, the flange 3b abuts against the limiting step 3a1 to achieve the rotation limit of the movable plate 3. At the same time, the buckle plate 7a flips and is fastened to the buckle 7b through the buckle hole 7a1 to lock the lid 2 and the bottom box 1. Since a reinforcing rib 1b is also formed on the inner side of the side wall where the buckle 7b is located, and the reinforcing rib 1b extends from the bottom wall of the bottom box 1 along the height direction of the side wall of the bottom box 1, it can effectively prevent the side wall from being recessed inward by the fastening force of the buckle 7b.
