A playing card packaging box

Abstract

A playing card packaging box comprises a bottom box and a cover, and a sliding and overturning connecting structure is formed by the cooperation of a convex shaft and a sliding groove. The sliding and overturning connecting structure enables the cover to slide along the sliding groove and overturn relative to the bottom box around the axis of the convex shaft at any position in the sliding stroke. Limiting structures are arranged at the ends of the sliding groove to limit the maximum sliding displacement of the cover. After the cover is overturned, it can be adjusted by sliding to at least partially form a stacked storage state with the bottom of the bottom box. The sliding and overturning connecting structure formed by the cooperation of the convex shaft and the sliding groove between the bottom box and the cover enables the cover to slide along the sliding groove and overturn around the axis of the convex shaft at any position, and the sliding stroke is controlled by the limiting structures at the ends of the sliding groove, so that the cover and the bottom of the bottom box are finally stacked and stored. This structure solves the problems of easy loss of the cover of the traditional playing card box and large space occupation after opening, and has the advantages of loss prevention, compact structure and convenient operation.

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] In existing technologies, playing cards, as a widely used entertainment product in home entertainment, bars, card rooms, and other scenarios, have always had a focus of research on packaging methods that prioritize portability and prevent loss. Traditional playing card boxes mostly adopt a two-part structure, which has significant drawbacks in practical use.

[0003] Specifically, the lid and base of a traditional playing card box are separate. When a user opens the box, the lid easily detaches, leading to its loss. This not only affects the normal use of the playing card box but also increases the cost and inconvenience for consumers. For example, in scenarios with multiple users, such as family gatherings, frequent opening and closing of the playing card box greatly increases the probability of the lid being lost. In public places such as bars and card rooms, where there is high turnover of people, the loss of lids from traditional playing card boxes is even more common. Furthermore, the loose structure of the lid and base after opening results in a bulky box that is inconvenient to store and carry.

[0004] In existing technologies, to address the issues of easily lost lids and loose structures in traditional playing card boxes, some improved solutions employ a nested inner and outer box structure. For example, the Chinese utility model patent application number 202322965893.0 (authorization announcement number CN221618549U) discloses a "Side-Opening Playing Card Box for Guandan," which uses the cooperation of the outer and inner boxes to allow the inner box to deflect and push out along a limiting groove, thus preventing the lid from completely separating. However, this solution still has significant shortcomings: when the user presses to take out cards, the inner box needs to unfold outwards at a certain angle to expose the card-taking opening, resulting in a significant increase in overall space occupied when open. This defect makes the playing card box inconvenient for temporary storage or carrying, limiting its practical application scenarios.

[0005] Therefore, there is an urgent need for a new solution for a playing card box that can prevent the top cover from being lost, maintain structural stability, and achieve compact storage when open, so as to completely solve the core pain points of traditional design. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a playing card packaging box that, through a sliding and flipping collaborative structure, can form a stable folded storage state when opened without easily losing the top cover, and is compact and easy to operate.

[0007] 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 top cover, wherein the bottom box and the top cover form a sliding flip connection structure through the cooperation of a convex shaft and a sliding groove;

[0008] The convex shaft slides into the groove, allowing the top cover to slide along the groove and rotate relative to the bottom box at any position within the sliding stroke.

[0009] The end of the slide is provided with a limiting structure to limit the maximum sliding displacement of the top cover;

[0010] After the top cover is flipped over, it can be adjusted by sliding so that it can at least partially overlap with the bottom of the box for storage.

[0011] To make the fit between the convex shaft and the sliding groove more flexible and meet different assembly requirements, preferably, the convex shaft is provided on two opposite sides of the bottom box, and the corresponding sliding groove is provided on two opposite inner walls of the top cover;

[0012] Alternatively, the convex shaft is provided on two opposite inner walls of the upper cover, and the corresponding sliding groove is provided on two opposite sides of the bottom box.

[0013] In order to make the sliding guide of the cam shaft more precise and to effectively limit the sliding stroke of the cam shaft, preferably, the sliding groove is a long strip groove, which extends laterally along the upper cover in the length direction and is closed at both ends and does not penetrate the end face of the component. The closed end of the sliding groove constitutes the limiting structure.

[0014] To make the fit between the convex shaft and the closed end of the slide groove tighter, reduce wobbling during sliding, and improve structural stability, preferably, the convex shaft is cylindrical, and the two closed ends of the slide groove are semi-circular arcs adapted to the convex shaft.

[0015] In order to clarify the setting position of the slide groove and make the sliding flip structure between the slide groove and the top cover more compact and reasonable, preferably, the top cover includes a top plate and two oppositely arranged first side plates, and the slide groove is set on the inner wall surface of the two first side plates.

[0016] To make the bottom box and the top cover fit more tightly when closed, preferably, the bottom box includes a bottom plate and a main side plate and three second side plates surrounding the bottom box;

[0017] The top and both sides of the main side plate are higher than the second side plate, forming a stepped structure;

[0018] When the top cover is closed, its top plate is flush with the top of the main side plate, and the two first side plates are flush with the two sides of the main side plate above the edge.

[0019] In order to adapt to the movement trajectory of the top cover when it flips, making the top cover flip more smoothly and reducing friction and jamming, preferably, the top edge of the second side plate, which is arranged opposite to the main side plate, is formed with a guide chamfer to adapt to the movement trajectory of the top cover when it flips.

[0020] To make the setting position of the convex shaft more reasonable and ensure the stability of the top cover flipping and sliding process, preferably, the convex shaft is symmetrically set on the side walls of the two second side plates of the bottom box, and the setting position is adjacent to the second side plate opposite to the main side plate.

[0021] In order to ensure that the top cover can effectively contact the bottom box when closed and stored, thereby improving the stability and sealing of the structure, preferably, the top plate of the top cover has downward-extending flanges at both ends.

[0022] With the top cover closed, the retaining edge abuts against the top of the second side panel of the bottom box;

[0023] When the top cover is flipped to the stacked storage state, the retaining edge abuts against the outer surface of the bottom plate of the bottom box.

[0024] To facilitate the user in retrieving cards from the bottom box, preferably, the bottom plate of the bottom box is provided with at least one through hole, which corresponds to the central area when the playing cards are stacked, and is used to make the playing cards bulge out by external pushing force to facilitate card retrieval.

[0025] Compared with existing technologies, the advantages of this invention are as follows: By setting a convex shaft and a sliding groove between the bottom box and the top cover, the sliding flip connection structure formed by the two allows the top cover to slide along the sliding groove and flip open around the axis of the convex shaft at any position. Simultaneously, the sliding stroke of the top cover is controlled by a limiting structure at the end of the sliding groove, ultimately achieving stacked storage of the top cover and the bottom of the bottom box. This structure innovatively solves the problems of traditional playing card box top covers being easily lost and occupying a large space after opening. First, the permanent cooperation between the convex shaft and the sliding groove ensures that the top cover will never detach from the bottom box during use; second, because the top cover can be stacked with the bottom of the bottom box after flipping, it overcomes the defects of traditional playing card boxes being loosely structured and occupying a large space after opening, ensuring that the packaging remains compact in the open state, facilitating storage and carrying; at the same time, this sliding flip connection structure is easy to operate, allowing users to open and close the packaging box with one hand through sliding and flipping actions, improving the user experience.

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

[0032] Figures 1-5 The present invention is shown as the preferred embodiment. 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 top cover 2, a convex shaft 1a, a sliding groove 2a, and a limiting structure 2a1, etc. The specific structure and connection method of each component are described below.

[0034] Specific structure of the base box and top cover: See reference Figures 1 to 3 As shown, the upper cover 2 includes a top plate 2b and two opposing first side plates 2c, with a sliding groove 2a disposed on the inner wall surface of the two first side plates 2c. The bottom box 1 includes a bottom plate 1b and a main side plate 1c and three second side plates 1d surrounding the bottom plate 1b. The top and side edges of the main side plate 1c are higher than the second side plates 1d, forming a stepped structure. When the upper cover 2 is in the closed state, its top plate 2b is flush with the top of the main side plate 1c of the bottom box 1, and the two first side plates 2c are flush with the raised edges of the main side plate 1c on both sides of the bottom box 1. The top edge of the second side plate 1d, which is opposite to the main side plate 1c, has a guide chamfer 1d1 to accommodate the movement trajectory of the upper cover 2 when it is flipped.

[0035] refer to Figure 2 As shown, the top plate 2b of the upper cover 2 extends downward at both ends to form a retaining edge 2d. When the upper cover 2 is in the closed state, the retaining edge 2d abuts against the top of the second side plate 1d of the bottom box 1. When the upper cover 2 is flipped to the storage state, the retaining edge 2d abuts against the outer surface of the bottom plate 1b of the bottom box 1.

[0036] refer to Figure 3 As shown, the bottom plate 1b of the bottom box 1 is provided with at least one through hole 1b1, which corresponds to the central area when the playing cards are stacked, and is used to make the playing cards bulge by external pushing force to facilitate card picking.

[0037] Specific connection structure between the bottom box and the top cover: See reference Figures 1 to 3As shown, the base box 1 and the top cover 2 form a sliding flip connection structure through the cooperation of the convex shaft 1a and the sliding groove 2a. The convex shaft 1a is cylindrical and is located on the side wall of the second side plate 1d on two opposite sides of the base box 1, and its position is adjacent to the second side plate 1d opposite to the main side plate 1c; the corresponding sliding groove 2a is located on the inner wall surface of the first side plate 2c on two opposite inner walls of the top cover 2. The convex shaft 1a and the sliding groove 2a are slidably engaged, allowing the top cover 2 to slide along the sliding groove 2a and flip relative to the base box 1 at any position around the axis of the convex shaft 1a during the sliding stroke. The sliding groove 2a is a long strip groove, its length direction is arranged along the transverse direction of the top cover 2, and both ends are closed and do not penetrate the end face of the component. The two closed ends of the sliding groove 2a are semi-circular arcs adapted to the convex shaft 1a. These closed ends constitute a limiting structure 2a1 to limit the maximum sliding displacement of the top cover 2.

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

[0039] 1. Opening and storage process

[0040] When the packaging box needs to be opened, the user pushes the top cover 2 to slide outward along the slide groove 2a, while the top cover 2 flips around the axis of the convex shaft 1a to open the top cover 2. (Refer to the flipping process for details.) Figure 4 As shown, the guide chamfer 1d1 adapts to the movement trajectory of the upper cover 2, making its flipping smoother. After the upper cover 2 flips 180° to a horizontal position, it continues to slide in the opposite direction along the slide groove 2a towards the inside of the bottom box 1 to a set position, so that the top plate 2b of the upper cover 2 fits against the bottom plate 1b of the bottom box 1, forming a compact storage structure with upper and lower layers, as shown in the figure. Figure 5 As shown. At this time, the vertical projections of the upper cover 2 and the bottom box 1 are almost completely overlapped, and the edge 2d abuts against the outer surface of the bottom plate 1b in the stacked storage state, further enhancing the stability of the structure.

[0041] 2. Closing and locking process

[0042] When the packaging box needs to be closed, slide the top cover 2 outward from its stored state along the slide groove 2a and flip it over. Then, move the flipped top cover 2 inward to abut against the main side panel 1c. At this point, the top plate 2b of the top cover 2 is flush with the top of the main side panel 1c, and the two first side panels 2c are also flush with the raised edges on both sides of the main side panel 1c. The retaining edge 2d also abuts against the top of the second side panel 1d. The top cover 2 is now closed. (See reference for details.) Figure 1 As shown. The cooperation between the convex shaft 1a and the sliding groove 2a, as well as the setting of the limiting structure 2a1, ensures the stability of the top cover 2 in the closed state, avoiding the problem of the top cover of traditional poker boxes being easily lost.

[0043] 3. Card drawing process

[0044] When it is necessary to take out the playing cards, the user can apply external force to the base plate 1b through the through hole 1b1 on the base plate 1b, so that the top of the stacked playing cards built into the base box 1 forms a high bulge, making it convenient for the user to take out the cards. This design solves the problem of inconvenience in taking out cards from traditional playing card boxes and greatly improves the user experience.
