Description

Technical Field

[0001] This utility model belongs to the field of packaging box technology, and in particular relates to a double-door paper box that is easy to display. Background Technology

[0002] As a crucial component for product protection and brand display, packaging boxes must not only ensure the safety of the contents but also consider user experience and visual appeal. Currently, most packaging boxes on the market adopt a top-opening structure. While this design performs reliably in conventional storage and transportation, it has significant limitations in product display. For example, for alcoholic beverages, gifts, or high-end consumer goods, consumers expect to be able to visually inspect the product's appearance, labels, or design details without completely removing the packaging. However, traditional top-opening boxes require users to remove the entire contents for a complete display, a process that is not only inconvenient but may also increase the risk of product damage. Especially in retail displays or gift-giving scenarios, it fails to achieve a synergistic display of the product and packaging, weakening the brand's visual impact and consumer engagement.

[0003] Therefore, there is an urgent need for a double-door cardboard box that can achieve a coordinated display of products and packaging. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing an easy-to-display double-door cardboard box that enables intuitive and coordinated display of products and packaging. It is easy to operate and has the advantages of stable structure, good display effect, and excellent user experience.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An easy-to-display double-door cardboard box, comprising: The box body has a front opening on its front side; A first vertical groove and a second vertical groove are respectively provided on both sides of the box body and near the front of the box body; A first side door and a second side door are respectively provided on both sides of the box body. The first side door and the second side door each include a side plate that is rotatably connected to the side of the box body and a door plate that is rotatably connected to the side plate. The side panels of the first side door and the second side door are attached to the side of the box body where they are located. The door panels of the first side door and the second side door extend into the box body through the first vertical groove and the second vertical groove respectively to close the front opening. When the side panel is rotated, the door panel will move outward from the first vertical groove and the second vertical groove to open the front opening.

[0006] Furthermore, the box body is provided with sliding grooves at both the top and bottom ends near the front of the box body. When the door panel is inserted into the box body through the first vertical groove and the second vertical groove, it will slide along the sliding grooves.

[0007] Furthermore, the door panel is provided with a first limiting protrusion at the upper and lower edges of the end away from the side panel, and the first limiting protrusion is connected to the sliding groove.

[0008] Furthermore, the sliding groove is provided with limiting blocks at both ends, which prevent the door panel from detaching from the first vertical groove and the second vertical groove when the door panel moves outward to the point where the first limiting protrusion abuts against the limiting block.

[0009] Furthermore, the door panel is provided with second limiting protrusions at the upper and lower edges of the end near the side panel. When the door panel extends into the box to close the front opening, the second limiting protrusions will pass over the limiting block and enter the slide groove.

[0010] Furthermore, a transition slope is provided at the edge of the second limiting protrusion.

[0011] Furthermore, both the first side door and the second side door are provided with pull straps at the connection between the side panel and the door panel, and the pull straps are located outside the box body.

[0012] Furthermore, the first side door and the second side door are also provided with reinforcing plates on the outside of the side panels.

[0013] Furthermore, the width and height of the front opening are both smaller than the width and height of the front of the box, and the height of the door panel is greater than the height of the front opening.

[0014] Furthermore, the first side door and the second side door have the same structure and are symmetrical on the left and right sides of the box body, and the width of the door panel is half the width of the front of the box body.

[0015] The beneficial effects of this utility model are: This invention utilizes a side door composed of a side panel and a door panel, along with a vertical groove on the box body, to enable the door panel to open and close the front opening, allowing the product to be displayed directly and completely without being removed from the box. A sliding groove and a first limiting protrusion within the box body precisely guide and limit the movement trajectory of the door panel. Limiting blocks at both ends of the sliding groove restrict the maximum outward opening of the door panel. A second limiting protrusion on the door panel ensures stable limiting when fully closed. A pull strap outside the box body facilitates quick and effortless pulling of the side door to open the packaging. A reinforcing plate on the outer side of the side panel enhances its structural strength. This invention provides a direct and coordinated display of the product and packaging, is easy to operate, and offers advantages such as a stable structure, excellent display effect, and superior user experience.

[0022] See appendix Figure 1 and attached Figure 2 Easy-to-display double-door cardboard boxes include: Box 1, the front of which has a front opening 110; The first vertical groove 120 and the second vertical groove 130 are respectively provided on both sides of the box body 1 and close to the front of the box body 1; The first side door 2 and the second side door 3 are respectively provided on both sides of the box body 1. The first side door 2 and the second side door 3 each include a side plate 4 that is rotatably connected to the side of the box body 1 and a door plate 5 that is rotatably connected to the side plate 4. The side panels 4 of the first side door 2 and the second side door 3 are attached to the side of the box 1 where they are located. The door panels 5 of the first side door 2 and the second side door 3 extend into the box 1 through the first vertical groove 120 and the second vertical groove 130 respectively to close the front opening 110. When the side panel 4 is rotated, the door panel 5 will move outward from the first vertical groove 120 and the second vertical groove 130 to open the front opening 110.

[0023] See appendix Figure 3 and attached Figure 4In the above embodiment, the box body 1 is a cuboid structure made of cardboard folded or spliced ​​together. The front of the box body 1 has a front opening 110, and the items will be placed into the box body 1 through the front opening 110. A first vertical groove 120 is provided vertically downward on the left side of the box body 1 near the front. The side panel 4 of the first side door 2 on the left side of the box body 1 can rotate relative to the side of the box body 1. The door panel 5 of the first side door 2 will extend into the first vertical groove 120 and move into or out of the box body 1 as the side panel 4 of the first side door 2 rotates. When the door panel 5 is completely moved into the box body 1 through the first vertical groove 120, the side panel 4 of the first side door 2 is in contact with the left side of the box body 1. At this time, the side panel 4 of the first side door 2 and the door panel 5 are in a perpendicular state to each other. When the door panel 5 moves out of the box body 1 from the first vertical groove 120, the side panel 4 of the first side door 2 rotates. The side panel 4 of the first side door 2 and the left side of the box body 1 change from a contact state to a state in which the two form an acute angle. At the same time, the side panel 4 of the first side door 2 and the door panel 5 also change from a perpendicular state to a state in which the two form an acute angle. A second vertical groove 130 is provided vertically downwards on the right side of the box body 1 near the front. The structure and opening / closing logic of the second side door 3 are the same as those of the first side door 2. When the door panels 5 of the first side door 2 and the second side door 3 are both moved into the box body 1, the two door panels 5 will mate and close the front opening 110. When the door panels 5 of the first side door 2 and the second side door 3 move to the sides, the two door panels 5 move away from each other and are in an open state. At this time, the product will be displayed through the front opening 110, allowing the product to be displayed directly and completely without having to be taken out of the box, which greatly improves the convenience and visual effect of the display.

[0024] See appendix Figure 5 and attached Figure 7 In the above embodiment, the upper and lower ends of the box body 1 near the front are provided with sliding grooves 140. When the door panel 5 extends into the box body 1 through the first vertical groove 120 and the second vertical groove 130, it will slide along the sliding groove 140. In this embodiment, the position of the sliding groove 140 corresponds to the position of the first vertical groove 120 and the second vertical groove 130, that is, after the door panel 5 extends into the box body 1 through the first vertical groove 120 and the second vertical groove 130, it is located in the sliding groove 140. When the door panel 5 moves into or out of the box body 1 through the first vertical groove 120 and the second vertical groove 130, a part of the door panel 5 will slide along the sliding groove 140 to avoid the door panel 5 getting stuck or tilted during the movement, so as to achieve smooth and stable opening and closing action. For details, please refer to the appendix. Figure 6 The door panel 5 has a first limiting protrusion 510 at both the upper and lower edges of the end away from the side panel 4, and the first limiting protrusion 510 is connected to the slide groove 140. In this embodiment, the first limiting protrusion 510 at both the upper and lower ends of the door panel 5, together with the slide groove 140, realizes the precise guidance and limitation of the movement trajectory of the door panel 5.

[0025] See appendix Figure 6In the above embodiment, limiting blocks 141 are provided at both ends of the slide groove 140. These blocks prevent the door panel 5 from detaching from the first vertical groove 120 and the second vertical groove 130 when the door panel 5 is moved outwards to the point where the first limiting protrusion 510 abuts against the limiting block 141. In this embodiment, by providing limiting blocks 141 at both ends of the slide groove 140, when the door panel 5 is pulled outwards to its maximum position, the first limiting protrusion 510 abuts against the limiting block 141, thereby preventing the door panel 5 from completely detaching from the first vertical groove 120 or the second vertical groove 130 due to excessive pulling, thus improving the product's durability and safety.

[0026] See appendix Figure 7 and attached Figure 8 In the above embodiment, the upper and lower edges of the door panel 5 near the side panel 4 are provided with second limiting protrusions 520. When the door panel 5 extends into the housing 1 to close the front opening 110, the second limiting protrusions 520 will pass over the limiting block 141 and enter the slide groove 140. In this embodiment, the second limiting protrusions 520 are provided on the inner side of the door panel 5 so that when the door panel 5 is closed, the second limiting protrusions 520 can pass over the limiting block 141 and enter the slide groove 140 to achieve the positioning of the closed state. At the same time, they work together with the first limiting protrusion 510 to ensure that the door panel 5 can be stably limited when fully closed and fully open. Furthermore, the edge of the second limiting protrusion 520 is provided with a transition slope 521. In this embodiment, during the closing process, the transition slope 521 of the door panel 5 can contact the limiting block 141 and generate guiding deformation, which facilitates the second limiting protrusion 520 to smoothly slide past the limiting block 141 and enter the slide groove 140, reducing the force required for the closing operation and improving the operating feel.

[0027] See appendix Figure 1 In the above embodiment, both the first side door 2 and the second side door 3 are provided with pull straps 6 at the connection between the side panel 4 and the door panel 5, and the pull straps 6 are located outside the box body 1. In this embodiment, the pull straps 6 outside the box body 1 provide the user with a clear point of force application, making it easy for the user to quickly and effortlessly pull the first side door 2 and the second side door 3 from the left and right sides to open the packaging, thus improving the convenience of opening the box and the user experience.

[0028] See appendix Figure 4 In the above embodiment, the first side door 2 and the second side door 3 are further provided with reinforcing plates 7 on the outside of the side panel 4. In this embodiment, the reinforcing plates 7 enhance the structural strength of the side panel 4, making the first side door 2 and the second side door 3 less prone to deformation after repeated opening and closing, while also improving the compressive strength of the side of the box body 1, making the overall packaging more stable and durable.

[0029] See appendix Figure 1In the above embodiment, the width and height of the front opening 110 are both smaller than the width and height of the front of the box body 1, and the height of the door panel 5 is greater than the height of the front opening 110. In this embodiment, the width and height of the front opening 110 are smaller than the width and height of the front of the box body 1, forming an edge blocking edge around the front opening 110 on the front of the box body 1. The height of the door panel 5 is greater than the height of the front opening 110, ensuring that the door panel 5 completely covers the front opening 110 and is within the edge blocking edge when closed, achieving a good sealing and blocking effect. In this embodiment, the first side door 2 and the second side door 3 have the same structure and are symmetrical on the box body 1. The width of the door panel 5 is half the width of the front of the box body 1. The rotating ends of the side panels of the first side door 2 and the second side door 3 are located at the connection between their respective sides and the back of the box body 1, ensuring that the double doors move in a coordinated manner, are subjected to uniform force, and have a neat and aesthetically pleasing visual effect when opening and closing.

[0030] In summary, this embodiment provides an easy-to-display double-door cardboard box. By setting a side door composed of a side panel 4 and a door panel 5, and a vertical groove on the box body, the door panel 5 can open and close the front opening 110, allowing the product to be displayed directly and completely without being removed from the box. By setting a sliding groove 140 and a first limiting protrusion 510 inside the box body 1, the movement trajectory of the door panel 5 is precisely guided and limited. By setting limiting blocks 141 at both ends of the sliding groove 140, the maximum position of the door panel 5 when pulled outward is limited. By setting a second limiting protrusion 520 on the door panel 5, the door panel 5 can obtain a stable limit when fully closed. By setting a pull strap 6 outside the box body 1, it is easy to quickly and effortlessly pull the side door to open the packaging. By setting a reinforcing plate 7 on the outside of the side panel 4, the structural strength of the side panel 4 is enhanced. This embodiment can achieve intuitive and coordinated display of the product and packaging, is easy to operate, and has the advantages of stable structure, good display effect, and excellent user experience.
