Abstract
Description
Technical Field
[0001] This application relates to the field of plastic products technology, and in particular to a packaging box. Background Technology
[0002] In the field of modern product packaging technology, plastic packaging boxes are widely used in the packaging and transportation of food and beverages, electronic products, and daily necessities due to their controllable cost, convenient molding, and excellent chemical resistance. However, the bottom of most existing plastic packaging boxes is designed as a smooth flat structure. This smooth surface makes the packaging box prone to sliding. For example, when placed on a smooth table, conveyor track, or shelf surface, the box is easily displaced due to insufficient friction. Furthermore, the bottom structure of the smooth flat surface of the packaging box is relatively weak. When multiple packaging boxes are stacked, the weight of the upper packaging boxes acts on the bottom surface, and due to the weak bottom structure, it is prone to plastic deformation, dents, or even cracks. Utility Model Content

The lower edge of the lower cover has a mesh rib, and the bottom of the storage groove has an annular groove surrounding the first protrusion corresponding to the edge of the lower cover.
[0005] The top cover according to the embodiments of this application has at least the following beneficial effects: When the packaging box is placed on a flat surface, the lower edge of the bottom cover is used to connect with the flat surface. A mesh rib is provided on the lower edge of the bottom cover. The mesh rib includes multiple intersecting ribs, thereby increasing the friction of the lower end of the bottom cover, making the packaging box less likely to slide relative to the flat surface, which is beneficial for the placement and transportation of the packaging box. At the same time, the mesh rib can also improve the structural strength of the lower end of the bottom cover, making the lower end of the bottom cover less likely to deform and be damaged when the packaging boxes are stacked. In addition, the middle part of the lower end of the bottom cover is concave inward toward the storage groove to form a groove, making the lower edge of the bottom cover narrower, thereby giving the lower end of the bottom cover better bending resistance and improving structural strength. Furthermore, when meat, fruit, or other watery foods are placed inside the packaging box of this application, the food can be placed on the first protrusion, and the blood in the meat or the water in the fruit can flow into the annular groove, preventing the liquid from affecting the storage of the food.

[0027] Reference Figure 1 and Figure 2 According to an embodiment of this application, a packaging box includes a lower cover 200 and an upper cover 100. The lower cover 200 has a storage groove 210, and the lower cover 200 is rotatably connected to the upper cover 100 to allow the storage groove 210 to be opened and closed. The lower end of the lower cover 200 is recessed inward toward the storage groove 210 to form a groove 220. The bottom of the storage groove 210 has a first protrusion 230 corresponding to the groove 220. The lower edge of the lower cover 200 has a mesh rib 240, and the bottom of the storage groove 210 has an annular groove 250 surrounding the first protrusion 230 corresponding to the edge of the lower cover 200.
[0028] It is understood that one side of the lower end of the upper cover 100 is connected to one side of the upper end of the lower cover 200. The upper cover 100 can be flipped relative to the lower cover 200 to fasten onto the lower cover 200, thereby sealing the storage slot 210, which can be used to store items or food. When the packaging box is placed on a flat surface, the lower edge of the lower cover 200 is used to contact the surface. A mesh rib 240 is provided on the lower edge of the lower cover 200. The mesh rib 240 includes multiple intersecting ribs, thereby increasing the friction of the lower end of the lower cover 200, making the packaging box of this application less likely to slide relative to the flat surface, which is beneficial for the placement and transportation of the packaging box of this application. At the same time, the mesh rib 240 can also increase the structural strength of the lower end of the lower cover 200, making the lower end of the lower cover 200 less likely to deform or be damaged when the packaging boxes of this application are stacked. It is also understood that the lower end of the lower cover 200 is recessed inward toward the storage groove 210 to form a groove 220. The cross-section of the groove 220 is roughly square, and the cross-section of the lower end of the lower cover 200 is also roughly square. Thus, the recessed groove 220 formed by the recessed lower end of the lower cover 200 toward the storage groove 210 makes the lower edge of the lower cover 200 narrower, thereby giving the lower end of the lower cover 200 better bending resistance and improving structural strength. Furthermore, since the lower end of the lower cover 200 is recessed inward toward the storage groove 210, the bottom of the storage groove 210 is correspondingly formed with a first protrusion 230. The first protrusion 230 is surrounded by an annular groove 250. When meat, fruit, or other watery foods are placed in the packaging box of this application, the food can be placed on the first protrusion 230, and the blood in the meat or the water in the fruit can flow into the annular groove 250, preventing the liquid from affecting the storage of the food.
[0029] Reference Figure 1 and Figure 2 According to some embodiments of this application, a placement groove 110 is formed in the middle of the upper end of the upper cover 100, and the outer contour dimension of the lower end of the lower cover 200 corresponds to the outer contour dimension of the placement groove 110.
[0030] It is understood that when multiple packaging boxes of this application are stacked, the lower end of the lower cover 200 of the upper packaging box can be inserted into the placement slot 110 at the upper end of the upper cover 100 of the lower packaging box, so that the stacked packaging boxes can be placed stably.
[0031] Reference Figure 1 and Figure 2 According to some embodiments of this application, a second protrusion 120 is formed in the middle of the placement groove 110, and the outer contour size of the second protrusion 120 corresponds to the outer contour size of the groove 220.
[0032] It is understood that when multiple packaging boxes of this application are stacked, the lower end of the lower cover 200 of the upper packaging box can be inserted into the placement groove 110 at the upper end of the upper cover 100 of the lower packaging box. At the same time, the second protrusion 120 of the upper packaging box can be inserted into the groove 220 of the lower packaging box to further limit the stacked packaging boxes and improve the placement stability of the stacked packaging boxes.
[0033] Reference Figure 1 and Figure 2 According to some embodiments of this application, the corner end of the second protrusion 120 is provided with a concave structure 121.
[0034] It is understood that the second protrusion 120 is located at the upper end of the cover 100. Promotional text or patterns can be formed on the second protrusion 120 by means of hot pressing, injection molding or printing. The cross-section of the second protrusion 120 is roughly square. When the packaging boxes of this application are stacked, since the second protrusion 120 needs to be inserted into the groove 220 of another packaging box, the corners of the second protrusion 120 are prone to being deformed by pressure. Therefore, by setting the concave structure 121 at the corners of the second protrusion 120, the four corners of the second protrusion 120 are recessed toward the center of the second protrusion 120, which improves the structural strength of the second protrusion 120 and reduces the risk of the corners of the second protrusion 120 being deformed by pressure.
[0035] Reference Figure 1 and Figure 2 According to some embodiments of this application, an arc-shaped groove 130 is provided at the upper end of the cover 100. A paddle 140 and a cut hole 150 are formed on the cover 100 corresponding to the position of the groove 130. The paddle 140 can swing relative to the cover 100 so that the paddle 140 can cover or open the cut hole 150.
[0036] It is understandable that an arc-shaped groove 130 is made at the upper end of the cover 100 so that a lever 140 is formed on the cover 100. The groove 130 is a non-closed structure, so the lever 140 is still connected to the cover 100, and the lever 140 can swing relative to the cover 100. When the lever 140 swings, the cut hole 150 of the cover 100 can be exposed, or the lever 140 can be swung back to its original position to cover the cut hole 150. Specifically, under normal use, the lever 140 covers the cut hole 150 to ensure the airtightness of the storage compartment 210. In other usage environments, the packaging box may store fruits or cooked food, requiring the packaging box to have a certain degree of ventilation. In this case, the lever 140 can be pressed to make the lever 140 swing relative to the top cover 100, exposing the cut hole 150. The storage compartment 210 is connected to the outside through the cut hole 150, thereby achieving a ventilation effect. When ventilation is not required, the lever 140 can be swung back to the position covering the cut hole 150.
[0037] It is also understandable that the groove 130 is set to be arc-shaped, so that one side of the hole 150 is also arc-shaped, similar to the curvature of a fingernail, so that the finger can push the paddle 140 and pass through the hole 150.
[0038] Reference Figure 1 According to some embodiments of this application, the top cover 100 is provided with an annular rib 160, the annular rib 160 surrounds the edge of the placement groove 110, and the groove 130 is provided corresponding to the corner end of the placement groove 110 and passes through the annular rib 160.
[0039] Understandably, the annular rib 160 surrounds the edge of the placement groove 110 to improve the structural strength of the upper cover 100. Furthermore, the groove 130 is formed at the corner of the placement groove 110 and penetrates the annular rib 160, corresponding to the corner of the annular rib 160. It should be understood that the structural strength at the corner of the annular rib 160 is higher. Placing the groove 130 at the corner of the annular rib 160 reduces the impact of the groove 130 on the structural strength of the upper cover 100. Moreover, the intersection of the groove 130 and the annular rib 160 further reduces the impact of the groove 130 on the structural strength of the annular rib 160.
[0040] Reference Figure 1 and Figure 2 According to some embodiments of this application, the upper cover 100 is provided with a slot 170, and the slot wall of the slot 170 is provided with a limiting protrusion 171. The lower cover 200 is provided with a snap-fit structure 260, and the side of the snap-fit structure 260 is provided with a limiting groove 261. The snap-fit structure 260 is inserted into the slot 170, and the limiting protrusion 171 is inserted into the limiting groove 261.
[0041] Understandably, when the upper cover 100 and the lower cover 200 are closed, the snap-fit structure 260 of the lower cover 200 can snap into the snap-fit groove 170 to restrict the opening of the upper cover 100 and the lower cover 200. Specifically, the limiting protrusion 171 in the snap-fit groove 170 can snap into the limiting groove 261 of the snap-fit structure 260, thereby further restricting the opening of the upper cover 100 and the lower cover 200 to ensure that the upper cover 100 and the lower cover 200 can remain in the closed state.
[0042] Reference Figure 2 According to some embodiments of this application, a first handle portion 270 is provided on the side of the lower cover 200 away from the connection position between the lower cover 200 and the upper cover 100, and the first handle portion 270 protrudes from the lower edge of the upper cover 100.
[0043] Understandably, when the upper cover 100 and the lower cover 200 are closed, the first handle portion 270 will protrude from the lower edge of the upper cover 100. Thus, when it is necessary to open the upper cover 100 and the lower cover 200, the upper cover 100 and the lower cover 200 can be opened by grasping the first handle portion 270 and the upper cover 100 to apply a force that separates the upper cover 100 and the lower cover 200. The first handle portion 270 is provided with a position for applying force to facilitate opening the upper cover 100 and the lower cover 200.
[0044] Reference Figure 2 According to some embodiments of this application, the first handle portion 270 is formed with a plurality of protrusions 271.
[0045] It is understandable that by providing multiple protrusions 271 on the first handle portion 270, the surface friction of the first handle portion 270 is increased, making it easier to grip, and the structural strength of the first handle portion 270 is also improved.
[0046] Reference Figure 2 According to some embodiments of this application, a second handle portion 180 is provided on the side of the upper cover 100 away from the connection position between the upper cover 100 and the lower cover 200. The second handle portion 180 protrudes from the upper edge of the lower cover 200, and the second handle portion 180 is offset from the first handle portion 270 in the horizontal direction.
[0047] Understandably, when the upper cover 100 and the lower cover 200 are closed, the second handle portion 180 will protrude from the upper edge of the lower cover 200, and the second handle portion 180 and the first handle portion 270 are offset. Thus, when it is necessary to open the upper cover 100 and the lower cover 200, the force that separates the upper cover 100 and the lower cover 200 can be applied by grasping the first handle portion 270 and the second handle portion 180, thereby opening the upper cover 100 and the lower cover 200. By setting the first handle portion 270 and the second handle portion 180 to provide the position for applying force, it is convenient to open the upper cover 100 and the lower cover 200.
[0048] Specifically, a protrusion 271 can be provided at the second handle part 180 to improve the structural strength of the friction of the second handle.
[0049] Reference Figure 2 Specifically, multiple reinforcing ribs 280 are provided on the periphery of both the upper cover 100 and the lower cover 200 to improve the structural strength of the upper cover 100 and the lower cover 200.
[0050] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
