Description

Technical Field

[0001] This application relates to product packaging technology, and more particularly to a packaging box. Background Technology

[0002] Paper packaging boxes are a common form of packaging. They are inexpensive and easy to process, and are widely used in food, medicine, daily necessities and other fields.

[0003] Paper packaging boxes can include rotary-opening types, which mainly rely on the folding and crease lines at the connection between the outer and inner boxes to achieve relative rotation. However, in existing rotary-opening packaging boxes, the opening angle between the inner and outer boxes is difficult to control and fix, and they are prone to accidental closure due to gravity or slight touch, making them inconvenient to use. Utility Model Content

[0004] This application provides a packaging box to solve the technical problem in the related art that the opening angle of a rotary-opening paper packaging box is difficult to control and fix.

[0005] This application provides a packaging box, including:

[0006] The inner box has a first receiving cavity inside;

[0007] The outer box has a second receiving cavity inside to accommodate the inner box. The outer box is connected to the inner box. The inner box can rotate relative to the outer box so that the inner box has a stored state that enters the second receiving cavity and an open state that exposes the first receiving cavity relative to the outer box.

[0008] The inner box and the outer box are provided with a sliding member, and the other box is provided with a snap-fit ​​member. The sliding member and the snap-fit ​​member are engaged. The inner box is configured to rotate relative to the outer box along the sliding path of the sliding member to switch between the storage state and the open state.

[0009] In some possible implementations, the sliding member is a groove provided on the side wall of the inner box, and the snap-fit ​​member is a limiting strip provided on the inner side wall of the outer box, the limiting strip being inclined and protruding toward the interior of the second receiving cavity.

[0010] In some possible implementations, at least one of the sliding grooves is provided on the two opposite outer side walls of the inner box, and at least one of the limiting strips is provided on the two opposite inner side walls of the outer box, with the sliding grooves and the limiting strips being connected accordingly.

[0011] In some possible implementations, the outer box includes a main board and a side panel disposed on one side of the main board, with a first crease between the main board and the side panel. The side panel is used to connect to the inner box and is configured to drive the inner box to rotate along the first crease to switch between the stored state and the opened state.

[0012] In some possible implementations, the side panel is bonded to one side of the inner box, and the end of the side panel opposite to the first crease protrudes from the inner box.

[0013] In some possible implementations, the outer box body further includes two auxiliary folding plates, which are respectively disposed on both sides of the side plate. The auxiliary folding plates have a second crease between them and the main board. The auxiliary folding plates are configured to fold relative to the main board along the second crease, and the folded auxiliary folding plates are attached to the inner sidewall of the outer box body.

[0014] In some possible implementations, the outer casing further includes two positioning plates located on opposite sides of the main board, and the positioning plates and the auxiliary folding plate are respectively located on adjacent sides of the main board;

[0015] The positioning plate has a third crease between it and the main board. The positioning plate is configured to fold relative to the main board along the third crease. The folded positioning plate is attached to the inner side wall of the outer box. The limiting strip is provided on the positioning plate.

[0016] In some possible implementations, the auxiliary folding plate has a clearance portion on the side facing the adjacent positioning plate, the clearance portion being used to avoid the folded positioning plate.

[0017] In some possible implementations, the outer box has a first opening on its side to avoid the rotation of the inner box, the inner box has a second opening communicating with the first receiving cavity, and the inner box has a toggle part on the side near the second opening, the toggle part being recessed relative to the side of the inner box.

[0018] In some possible implementations, the inner box is provided with a partition plate for dividing the first receiving cavity into at least two partition cavities, and the at least two partition cavities are spaced apart along the rotation path direction of the inner box.

[0019] The packaging box provided in this application has a sliding member on one of the inner box body and the outer box body, and a snap-fit ​​member on the other of the inner box body and the outer box body. The sliding member and the snap-fit ​​member are engaged. The inner box body is configured to rotate relative to the outer box body along the sliding path of the sliding member to switch between the storage state and the open state. Thus, the sliding member provides a clearly defined physical rotation path for the rotational movement of the inner box body, avoiding the problem of the inner box body easily shaking, shifting, or deviating when using indentation lines for connection in traditional technology, making the opening and closing process of the inner box body smoother and more controllable.

[0020] In addition, the sliding parts and the snap-fit ​​parts form a snap-fit ​​engagement, requiring the user to apply a certain amount of external force to switch the inner box between the storage and open states. At the same time, the inner box can also remain in its current position without external force, avoiding accidental closure due to the weight of the inner box itself, slight external shaking, or touch, which helps to improve the user experience.

It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in a sequence other than those illustrated or described herein.

[0041] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or apparatus.

[0042] As described in the background section, rotating paper packaging boxes mainly rely on the folding and crease lines at the connection between the outer and inner boxes to achieve relative rotation. However, in existing rotating packaging boxes, the opening angle between the inner and outer boxes is difficult to control and fix, and they are prone to accidental closure due to gravity or slight contact, making them inconvenient to use.

[0043] Based on the above description, one or more embodiments of this application provide a packaging box, which utilizes a slider on one of the inner box and the outer box, and a snap-fit ​​on the other of the inner box and the outer box. The slider and the snap-fit ​​engage, requiring the user to apply a certain external force to switch the inner box between the storage state and the open state. At the same time, the inner box can also remain in its current position without external force, avoiding accidental closure due to the weight of the inner box itself, slight external shaking or touch, which helps to improve the user experience.

[0044] The packaging box of the present application embodiment will be described below with reference to the accompanying drawings.

[0045] like Figure 1 As shown, the packaging box in this embodiment of the application includes an inner box 100 and an outer box 200.

[0046] The inner box 100 has a first receiving cavity 110 inside, and the outer box 200 has a second receiving cavity 210 inside to receive the inner box 100. The outer box 200 is connected to the inner box 100. The inner box 100 rotates relative to the outer box 200 so that the inner box 100 has a stored state that enters the second receiving cavity 210 and an open state that exposes the first receiving cavity 110 relative to the outer box 200. One of the inner box 100 and the outer box 200 is provided with a sliding member, and the other of the inner box 100 and the outer box 200 is provided with a snap-fit ​​member. The sliding member and the snap-fit ​​member are engaged. The inner box 100 is configured to rotate relative to the outer box 200 along the sliding path of the sliding member to switch between the stored state and the open state.

[0047] As can be seen from the above description, the packaging box of this application embodiment has a slider on one of the inner box body 100 and the outer box body 200, and a snap-fit ​​on the other of the inner box body 100 and the outer box body 200. The slider and the snap-fit ​​engage with each other. The inner box body 100 is configured to rotate relative to the outer box body 200 along the sliding path of the slider to switch between the storage state and the open state. Thus, the slider provides a clearly defined physical rotation path for the rotational movement of the inner box body 100, avoiding the problem of the inner box body 100 easily shaking, deviating and running off course when using the indentation line connection in the traditional technology, making the opening and closing process of the inner box body 100 smoother and more controllable.

[0048] In addition, the sliding part and the snap-fit ​​part form a snap-fit ​​engagement, so that the user needs to apply a certain amount of external force to drive the inner box 100 to switch between the storage state and the open state. At the same time, the inner box 100 can also remain in the current position without the action of external force, avoiding accidental closure due to the weight of the inner box 100 itself, slight external shaking or touch, which helps to improve the user experience.

[0049] The inner box 100 of the packaging box can be used to hold food such as tea bags, coffee bags, and candy, as well as beauty and personal care products such as eyeshadow palettes, powder compacts, and makeup brushes, or medicines and health products such as pills and capsules. The specific use scenario of the packaging box is not limited in this application embodiment.

[0050] In this embodiment, both the inner box 100 and the outer box 200 can be made of materials with certain bending and deformation properties, such as hard kraft paperboard, corrugated cardboard, or natural bamboo fiber laminate. Of course, in some embodiments, the inner box 100 and the outer box 200 can also be made of solid wood, plywood, or hard plastic board. When using materials that are not easily deformed or folded, such as solid wood or hard plastic board, the folding area can be thinned or additional flexible and deformable connection treatment can be made, as long as it can be bent along the fold to form the inner box 100 and the outer box 200.

[0051] like Figure 3 and Figure 4 As shown, in some embodiments, the sliding member is a groove 120 provided on the side wall of the inner box 100, and the snap-fit ​​member is a limiting strip 230 provided on the inner side wall of the outer box 200. The limiting strip 230 is inclined and protrudes towards the inside of the second receiving cavity 210.

[0052] The slide groove 120 forms a track on the side wall of the inner box 100 that restricts the rotational offset of the inner box 100. When the inner box 100 rotates relative to the outer box 200, the limiting strip 230 is always constrained to slide in the slide groove 120, guiding the inner box 100 to move along the preset sliding path of the slide groove 120. This eliminates the shaking or offset problem that easily occurs when the inner box 100 rotates only by the pre-indentation line in the traditional technology, making the rotation process smoother and more controllable.

[0053] In addition, the limiting strip 230 is inclined and protrudes towards the inside of the second receiving cavity 210, forming a wedge-shaped contact with the edge of the slide groove 120. The locking engagement between the limiting strip 230 and the slide groove 120 creates a certain frictional force when the inner box 100 rotates freely relative to the outer box 200. The frictional force generated by this locking engagement restricts the free rotation of the inner box 100 relative to the outer box 200. The inner box 100 can only rotate when it overcomes this frictional force under the action of external force, effectively preventing the inner box 100 from accidentally closing due to slight shaking or gravity.

[0054] Furthermore, Figure 2 and Figure 5 In the middle, at least one sliding groove 120 is provided on each of the two opposite outer side walls of the inner box 100, and at least one limiting strip 230 is provided on each of the two opposite inner side walls of the outer box 200. The sliding groove 120 and the limiting strip 230 are connected accordingly.

[0055] For example, a sliding groove 120 is provided on each of the opposite side walls of the inner box 100, and a limiting strip 230 is provided on each of the opposite inner side walls of the outer box 200. The sliding grooves 120 and the limiting strips 230 on both sides are mirror-symmetrically distributed, thereby forming two sets of synchronously operating sliding structures. When the inner box 100 rotates relative to the outer box 200, the limiting strips 230 on both sides of the outer box 200 slide synchronously in the two sliding grooves 120, thereby making the two sides of the outer box 200 evenly stressed and preventing the inner box 100 from tilting and jamming during rotation.

[0056] As an alternative implementation, the sliding member is a groove 120 provided on the inner side wall of the outer box 200, and the locking member is a limiting strip 230 provided on the side wall of the inner box 100. The limiting strip 230 is inclined and protrudes towards the inner side wall of the outer box 200. With this design, the inner box 100 can also have a certain frictional force relative to the outer box 200, which restricts the free rotation of the inner box 100 relative to the outer box 200.

[0057] For example, the outer box 200 has a first opening 220 on its side to avoid the rotation of the inner box 100, the inner box 100 has a second opening 130 that communicates with the first receiving cavity 110, and the inner box 100 has a toggle part 140 on the side near the second opening 130, the toggle part 140 being recessed relative to the side of the inner box 100.

[0058] like Figure 1 As shown, Figure 1 In this design, both the outer box 200 and the inner box 100 are rectangular boxes. The outer box 200 has openings on both adjacent sides. When the inner box 100 rotates relative to the outer box 200, the second opening 130 is driven outward by the inner box 100 to expose the first opening 220, thereby exposing the first receiving cavity 110 of the inner box 100, which facilitates the display of the items in the inner box 100.

[0059] The actuating part 140 is an arc-shaped groove located on the side of the inner box 100. When using the packaging box, the user can manually actuate the actuating part 140 to rotate the inner box 100 relative to the outer box 200 and expose it, thereby making it more convenient and flexible to switch between the storage state and the open state of the inner box 100.

[0060] like Figure 2 As shown, in some embodiments, the outer box 200 includes a main board 240 and a side plate 250 disposed on one side of the main board 240. A first crease 251 is provided between the main board 240 and the side plate 250. The side plate 250 is used to connect with the inner box 100. The side plate 250 is configured to drive the inner box 100 to rotate along the first crease 251 to switch between a stored state and an open state.

[0061] Here, the outer box 200 and the inner box 100 can be made of a single piece of cardboard, which is cut, folded and glued together to form the outer box 200. A first crease 251 is pre-set between the main board 240 and the side panel 250. After the side panel 250 is connected to the inner box 100, the first crease 251 forms a hinge-like structure. The hinge-like structure of the first crease 251 forms the rotation axis of the inner box 100, providing a basic degree of rotational freedom for the rotation of the inner box 100. The rotation path of the inner box 100 is further constrained by the snap-fit ​​and sliding parts, which further improves the connection strength and stability between the inner box 100 and the outer box 200.

[0062] The side panel 250 and the inner box 100 can be directly glued together, or the side panel 250 and the side wall of the inner box 100 can be detachably glued together with Velcro. This embodiment of the application does not impose an absolute limitation on this.

[0063] For example, the side panel 250 protrudes from the inner box 100 at one end opposite to the first crease 251. Thus, the side panel 250 actually has a protruding portion relative to the inner box 100. When the inner box 100 is in the stored state, it is completely retracted into the outer box 200. By providing the protruding portion of the side panel 250, the user can directly and manually move the protruding portion of the side panel 250 to rotate the inner box 100 relative to the outer box 200, thereby facilitating the removal of the stored inner box 100 from the outer box 200.

[0064] Here, the inner box 100 is in the stored state, that is, completely inserted into the outer box 200 and not exposed through the second opening 130. The inner box 100 is in the open state, that is, at least part of the second opening 130 is exposed through the outer box 200, allowing items inside the inner box 100 to be taken out or placed in.

[0065] For example, the outer box 200 also includes two auxiliary folding plates 260, which are respectively disposed on both sides of the side plate 250. The auxiliary folding plates 260 and the main board 240 have a second crease 261. The auxiliary folding plates 260 are configured to fold relative to the main board 240 along the second crease 261. The folded auxiliary folding plates 260 are attached to the inner side wall of the outer box 200.

[0066] After the auxiliary folding plate 260 is folded along the second fold 261, it can be bonded to the main board 240 of the outer box 200, thereby preventing the auxiliary folding plate 260 from freely deforming and interfering with the inner box 100. After being folded along the second fold 261, the auxiliary folding plate 260 is attached to the inner side wall of the outer box 200. The auxiliary folding plate 260 provides a rigid backing for the inner side wall of the outer box 200, further enhancing the overall structural strength of the outer box 200 and helping to reduce local deformation of the outer box 200.

[0067] For example, the outer box 200 also includes two positioning plates 270, which are located on opposite sides of the main board 240, and the positioning plates 270 and the auxiliary folding plate 260 are located on adjacent sides of the main board 240 respectively; there is a third fold 271 between the positioning plate 270 and the main board 240, and the positioning plate 270 is configured to fold relative to the main board 240 along the third fold 271, and the folded positioning plate 270 is attached to the inner side wall of the outer box 200, and the limiting strip 230 is provided on the positioning plate 270.

[0068] Depend on Figure 2 As can be seen, after the positioning plate 270 is folded relative to the third crease 271 and the auxiliary crease 260 is folded relative to the second crease 261, the positioning plate 270 and the auxiliary crease 260 actually cover most of the inner sidewall main plate 240 area of ​​the outer box 200, providing a rigid backing for the sidewall of the outer box 200. The setting of the positioning plate 270 and the auxiliary crease 260 can enhance the overall structural strength and deformation resistance of the outer box 200.

[0069] Of course, after the positioning plate 270 is folded along the third crease 271, it can also be bonded to the main board 240 to avoid the positioning plate 270 from freely deforming and interfering with the inner box 100.

[0070] Furthermore, the auxiliary folding plate 260 has a clearance portion 262 on the side facing the adjacent positioning plate 270, which is used to avoid the folded positioning plate 270.

[0071] Figure 2 In this design, the clearance portion 262 is an inclined transition portion provided on the side of the auxiliary folding plate 260 facing the positioning plate 270. When the auxiliary folding plate 260 is not provided with the clearance portion 262, after the auxiliary folding plate 260 is folded along the second crease 261, at least part of the auxiliary folding plate 260 will overlap with the positioning plate 270. The overlapping part is likely to form an abrupt protrusion inside the outer box 200, affecting the normal rotation of the inner box 100. Therefore, by providing the clearance portion 262, the folded auxiliary folding plate 260 and the positioning plate 270 are on the same horizontal plane, making the rotation of the inner box 100 inside the outer box 200 smoother and avoiding the inner box 100 being blocked or interfered with by the auxiliary folding plate 260 or the positioning plate 270, thus affecting its normal rotation.

[0072] like Figure 2 As shown, the outer box 200 is made entirely of one-piece cardboard material. A limiting strip 230 is mounted on the positioning plate 270, and a pre-set crease exists between the limiting strip 230 and the positioning plate 270. The limiting strip 230 bends relative to the positioning plate 270 along the pre-set crease, thereby forming a structure that tilts and protrudes towards the second receiving cavity 210 inside the outer box 200. Furthermore, the outer box 200 should also have other plate portions that enclose and form the second receiving cavity. These plate portions only need to be able to properly enclose and form the cavity. Figure 1 The outer box shown in the diagram is 200mm.

[0073] For example, such as Figure 6 As shown, the inner box 100 also includes a partition plate 150, which divides the first receiving cavity 110 into at least two partition cavities. These at least two partition cavities are spaced apart along the rotation path of the inner box 100. Here, the partition plate 150 can be a fixed cardboard piece that divides the first receiving cavity 110. The partition plate 150 can be directly inserted and snapped into the first receiving cavity 110, or it can be directly bonded and fixed to the plate portion surrounding the first receiving cavity 110. This embodiment does not impose absolute limitations on this aspect.

[0074] In this embodiment, the inner box 100 is provided with two partition plates 150, which divide the first receiving cavity 110 into three partition cavities. Of course, the number of partition plates 150 can be flexibly adjusted. By providing partition plates 150 in the inner box 100, the interior of the inner box 100 is divided into different partition cavities, so that different items can be placed in the partition cavities respectively, making the use of the inner box 100 more flexible and convenient.

[0075] It should be noted that, in the embodiments of this application, Figure 2 This is a schematic diagram of the printing die for the outer box 200. The outer box 200 is cut using a die during the production process. Figure 2 Based on the corresponding schematic outline, the outer box body is folded 200 degrees and glued together to form the shape. Figure 3 The three-dimensional box shown in the diagram; similarly, Figure 5 This is a schematic diagram of the printing die for the inner box 100. The inner box 100 is cut using a die during the production process. Figure 5 Based on the corresponding schematic outline, the inner box is then folded 100 degrees and glued together to form the shape. Figure 4 The diagram shows a three-dimensional box.

[0076] An exemplary usage process of the packaging box in this application embodiment is as follows:

[0077] When a user needs to open the packaging box, they should first move the protruding part of the side panel 250 of the outer box 200 by hand. The side panel 250 will cause the inner box 100 to rotate relative to the outer box 200. During this process, the partition cavities inside the inner box 100 will gradually be exposed. Since the three partition cavities are spaced apart along the rotation path of the inner box 100, the three partition cavities will be exposed in sequence as the rotation angle increases. Therefore, the user can adjust the rotation angle of the inner box 100 according to the items needed.

[0078] After the inner box 100 is rotated to a certain angle, the user can manually move the actuating part 140 on the inner box 100 to continue rotating the inner box 100 until the inner box 100 is completely exposed. Throughout the rotation process, the limiting strip 230 and the sliding groove 120 are always engaged, and the friction between the inner box 100 and the outer box 200 restricts the free rotation of the inner box 100, preventing the inner box 100 from accidentally closing due to vibration or gravity.

[0079] Other embodiments of this application will readily occur to those skilled in the art upon consideration of the specification and practice of the utility models disclosed herein. This application is intended to cover any variations, uses, or adaptations of this application that follow the general principles of this application and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this application are indicated by the following claims.

[0080] It should be understood that this application is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this application is limited only by the appended claims.
