Description

Technical Field

[0001] This utility model relates to the technical field of pet supplies, and in particular to a packaging box that can be transformed into a sand tray. Background Technology

[0002] Currently, pet litter is typically packaged in sealed bags. For ease of transport and aesthetics, sellers usually store these bags in boxes during shipping. However, these boxes are only for transportation, have a limited function, and are rarely used by consumers after receipt, resulting in resource waste. Furthermore, the fixed shape and large size of existing litter boxes make them inconvenient to carry. When pet owners take their pets outdoors or to temporary locations, it's difficult to quickly find suitable containers to hold the litter and provide a place for their pets to relieve themselves, leading to direct defecation on the ground, impacting environmental hygiene, and increasing the difficulty for pet owners to clean up and collect pet waste. Utility Model Content

[0003] The purpose of this utility model is to provide a packaging box that can be transformed into a sand disc, which has the advantages of simple structure, reasonable design and multiple functions.

[0004] The technical solution adopted by this utility model is: a packaging box that can be deformed into a sand disc, which is formed by folding a folding plate. The folding plate has a connecting plate A, a connecting plate B, a connecting plate C, a connecting plate D and a connecting plate E connected in sequence; the connecting plate A, the connecting plate B, the connecting plate C, the connecting plate D and the connecting plate E are all rectangular outlines.

[0005] Connecting plate A and connecting plate B are separated by folded edge L1, connecting plate B and connecting plate C are separated by folded edge L2, connecting plate C and connecting plate D are separated by folded edge L3, and connecting plate D and connecting plate E are separated by folded edge L4.

[0006] Folded plate section A1 and folded plate section A2 are respectively connected to the two sides of the connecting plate section A. Folded plate section A1 is separated from the connecting plate section A by folded edge L11 and is bent to be perpendicular to the connecting plate section A. Folded plate section A2 is separated from the connecting plate section A by folded edge L12 and is bent to be perpendicular to the connecting plate section A.

[0007] Folded plate section B1 and folded plate section B2 are respectively connected to the two sides of the connecting plate section B. Folded plate section B1 is separated from the connecting plate section B by folded edge L21 and is bent to be perpendicular to the connecting plate section B. Folded plate section B2 is separated from the connecting plate section B by folded edge L22 and is bent to be perpendicular to the connecting plate section B.

[0008] The connecting plate A is bent through the folded edge L1 to be perpendicular to the connecting plate B, and the folded plate A1 is connected and fixed to the folded plate B1, and the folded plate A2 is connected and fixed to the folded plate B2;

[0009] Folded plate parts C1 and C2 are respectively connected to the two sides of the connecting plate part C. Folded plate part C1 is separated from the connecting plate part C by a folded edge L31 and is bent to be perpendicular to the connecting plate part C. Folded plate part C2 is separated from the connecting plate part C by a folded edge L32 and is bent to be perpendicular to the connecting plate part C. Neither folded plate part C1 nor folded plate part C2 is permanently connected or fixed to other folded plate parts.

[0010] Folded plate parts D1 and D2 are connected to the two sides of the connecting plate part D respectively. Folded plate part D1 is separated from the connecting plate part D by folded edge L41 and is bent to be perpendicular to the connecting plate part D. Folded plate part D2 is separated from the connecting plate part D by folded edge L42 and is bent to be perpendicular to the connecting plate part D.

[0011] Folded plate section E1 and folded plate section E2 are respectively connected to the two sides of the connecting plate section E. Folded plate section E1 is separated from the connecting plate section E by folded edge L51 and is bent to be perpendicular to the connecting plate section E. Folded plate section E2 is separated from the connecting plate section E by folded edge L52 and is bent to be perpendicular to the connecting plate section E.

[0012] The connecting plate part E is bent through the folded edge L4 to be perpendicular to the connecting plate part D, while the folded plate part E1 is connected and fixed to the folded plate part D1, and the folded plate part E2 is connected and fixed to the folded plate part D2;

[0013] The packaging box is opened and closed using folded edges L2 and L3. When closed, connecting plate B and connecting plate D are nearly parallel, and connecting plate A and connecting plate E are nearly overlapping, so that a closed storage space is formed inside. When opened, connecting plate B, connecting plate C, and connecting plate D are parallel or overlapping, so that a box-shaped container with an opening at the top can be formed.

[0014] Perforations are formed on the folding plate parts B1, C1, D1, B2, C2, and D2. The perforations are used to provide different insertion channels for the connecting components, thereby providing different connection and fixing positions.

[0015] The working principle of this utility model is as follows:

[0016] When transporting bagged pet litter, the packaging box is bent at edge L3, making connecting plate C nearly parallel to connecting plate E. The bagged pet litter is then placed within the space enclosed by connecting plate C, connecting plate D, folded plate D1, folded plate D2, and connecting plate E. The packaging box is then bent at edge L2, making connecting plate B nearly parallel to connecting plate D, and connecting plate A nearly overlapping connecting plate E, thus creating a sealed interior. The packaging features a storage space for bagged pet litter, facilitating its transport. When a litter box is needed for pet use, the box is bent at edges L2 and L3, causing connecting plates B, C, and D to be parallel or overlap, transforming the box into an open-top container. Pet litter can then be poured from the bag into the box, allowing it to function as a litter box. This design makes the packaging box more versatile, economical, and environmentally friendly.

[0017] Furthermore, the packaging box that can deform into a sand tray, as described above, also includes a first reinforcing plate and a second reinforcing plate. When the packaging box is in the unfolded state, the first reinforcing plate is simultaneously connected to the folding plate parts B1, C1, and D1 via a connecting assembly, and the second reinforcing plate is simultaneously connected to the folding plate parts B2, C2, and D2 via a connecting assembly. By adding the first and second reinforcing plates, the structure of the folding plate parts C1 and C2 is made more stable, preventing the folding plate parts C1 and C2 from deforming due to sand particle compression.

[0018] Furthermore, in the aforementioned packaging box that can transform into a sand tray, the connecting assembly includes a first clamping member and a second clamping member. The first clamping member is an elongated structure, with a clamping head and a toothed section sequentially formed along its length. The second clamping member has a fitting hole and a toothed section. The second clamping member is slidably fitted onto the toothed section of the first clamping member through the fitting hole. The toothed section engages with the toothed section, allowing the first clamping member to slide only in one direction toward the clamping head. A clamping and fixing space is formed between the second clamping member and the clamping head. This design makes the installation and fixing of the first and second reinforcing plates relatively convenient.

[0019] Furthermore, in the aforementioned packaging box that can deform into a sand disc, the outer contour of the cross-section of the toothed segment is rectangular, and the perforation is a rectangular hole that matches the outer contour of the cross-section of the toothed segment.

[0020] Furthermore, in the aforementioned packaging box that can transform into a sand disc, the first clamping component and the second clamping component are made of plastic.

[0021] Furthermore, in the aforementioned deformable packaging box that can be converted into a sand tray, the lengths of folded edges L1 and L2 are longer than the lengths of folded edges L3 and L4, the lengths of folded edges L11 and L12 are correspondingly longer than the lengths of folded edges L51 and L52, and the lengths of folded edges L21 and L22 are correspondingly longer than the lengths of folded edges L41 and L42. This design ensures smooth closure when the packaging box is switched to the closed state, and prevents significant deformation when the connecting plate C and / or connecting plate D are stacked on the connecting plate B in the unfolded state, thus ensuring that the shape of the resulting box-shaped container meets expectations.

[0022] Furthermore, in the aforementioned packaging box that can transform into a sand tray, a waterproof membrane layer is provided on one or both sides of the folding panel. When the packaging box is in the unfolded state, the waterproof membrane layer can prevent pet urine in the sand storage space from seeping through the folding panel into the external environment.

[0023] Furthermore, as described above, in a packaging box that can transform into a sand tray, the folding panels are made of rigid cardboard.

[0024] The advantages of this utility model are: simple structure, reasonable design, and multiple functions. Attached Figure Description

[0033] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0034] Example 1

[0035] like Figures 1 to 3 As described in Example 1, a packaging box that can be deformed into a sand tray is formed by folding a folding plate 1. The folding plate 1 is made of rigid cardboard material, and connecting plate parts A, B, C, D and E are formed on the folding plate 1 in sequence. Connecting plate parts A, B, C, D and E are all rectangular in outline.

[0036] Connecting plate A and connecting plate B are separated by folded edge L1, connecting plate B and connecting plate C are separated by folded edge L2, connecting plate C and connecting plate D are separated by folded edge L3, and connecting plate D and connecting plate E are separated by folded edge L4.

[0037] Folded plate section A1 and folded plate section A2 are respectively connected to the two sides of the connecting plate section A. Folded plate section A1 is separated from the connecting plate section A by folded edge L11 and is bent to be perpendicular to the connecting plate section A. Folded plate section A2 is separated from the connecting plate section A by folded edge L12 and is bent to be perpendicular to the connecting plate section A.

[0038] Folded plate section B1 and folded plate section B2 are respectively connected to the two sides of the connecting plate section B. Folded plate section B1 is separated from the connecting plate section B by folded edge L21 and is bent to be perpendicular to the connecting plate section B. Folded plate section B2 is separated from the connecting plate section B by folded edge L22 and is bent to be perpendicular to the connecting plate section B.

[0039] Folded plate A1 and folded plate A2 are located between folded plate B1 and folded plate B2. Connecting plate A is bent through folded edge L1 to be perpendicular to connecting plate B. Folded plate A1 and folded plate B1 are connected and fixed by adhesive, tape or other bonding methods. Folded plate A2 and folded plate B2 are connected and fixed by adhesive, tape or other bonding methods.

[0040] Folded plate parts C1 and C2 are respectively connected to the two sides of the connecting plate part C. Folded plate part C1 is separated from the connecting plate part C by a folded edge L31 and is bent to be perpendicular to the connecting plate part C. Folded plate part C2 is separated from the connecting plate part C by a folded edge L32 and is bent to be perpendicular to the connecting plate part C. Neither folded plate part C1 nor folded plate part C2 is permanently connected or fixed to other folded plate parts.

[0041] Folded plate parts D1 and D2 are connected to the two sides of the connecting plate part D respectively. Folded plate part D1 is separated from the connecting plate part D by folded edge L41 and is bent to be perpendicular to the connecting plate part D. Folded plate part D2 is separated from the connecting plate part D by folded edge L42 and is bent to be perpendicular to the connecting plate part D.

[0042] Folded plate section E1 and folded plate section E2 are respectively connected to the two sides of the connecting plate section E. Folded plate section E1 is separated from the connecting plate section E by folded edge L51 and is bent to be perpendicular to the connecting plate section E. Folded plate section E2 is separated from the connecting plate section E by folded edge L52 and is bent to be perpendicular to the connecting plate section E.

[0043] Folded plate parts E1 and E2 are located between folded plate parts D1 and D2. Connecting plate part E is bent through folded edge L4 and is perpendicular to connecting plate part D. Folded plate part E1 and folded plate part D1 are connected and fixed by adhesive, tape or other bonding methods. Folded plate part E2 and folded plate part D2 are connected and fixed by adhesive, tape or other bonding methods.

[0044] The packaging box is opened and closed using folded edges L2 and L3. In the closed state: connecting plate B and connecting plate D are nearly parallel, connecting plate C and connecting plate E are nearly parallel, folded plate C1 and folded plate C2 are embedded between folded plate D1 and folded plate D2, folded plate D1 and folded plate D2 are embedded between folded plate A1 and folded plate A2, and connecting plate A and connecting plate E nearly overlap, so that a closed storage space is formed inside. In the open state: connecting plate B, connecting plate C, and connecting plate D are parallel to each other, so that a box-shaped container with an opening at the top can be formed.

[0045] Perforations (not shown in the drawings) are formed on the folding plate parts B1, C1, D1, B2, C2, and D2. The perforations are used to provide different insertion channels for the connecting assembly 4, thereby providing different connection and fixing positions.

[0046] The working principle of this embodiment is as follows:

[0047] When transporting bagged pet litter, the packaging box is bent via fold L3, making connecting plate C nearly parallel to connecting plate E. Folding plates C1 and C2 are moved by connecting plate C to between folding plates D1 and D2. The bagged pet litter is then placed within the space enclosed by connecting plates C, D, D1, D2, and E. The packaging box is then bent via fold L2, making connecting plate B nearly parallel to connecting plate D. Folding plates B1 and B2 are moved by connecting plate B to the outside of folding plates D1 and D2, respectively, causing folding plates D1 and D2 to be embedded... Between folding plate A1 and folding plate A2, the sides of connecting plate A and connecting plate E facing away from connecting plate C are fitted together, allowing the packaging box to maintain its shape and forming a closed storage space inside. This allows bagged pet litter to be placed in the storage space, facilitating the transportation of bagged pet litter. When a litter box is needed for pet use, the packaging box is bent through folding edges L2 and L3, making connecting plate B, connecting plate C, and connecting plate D parallel or overlapping each other, thus transforming the packaging box into a box-shaped container with an open top. At this time, pet litter can be poured from the bag into the packaging box, making the packaging box usable as a pet litter box. This design makes the packaging box more versatile, more economical, and more environmentally friendly.

[0048] like Figure 3 As shown, this embodiment also includes a first reinforcing plate 2 and a second reinforcing plate 3. Each of the first and second reinforcing plates has three perforations. When the packaging box is in the unfolded state, one side of the first reinforcing plate 2 is simultaneously attached to the folding plate portion B1 and the folding plate portion D1, and the other side of the first reinforcing plate 2 is attached to the folding plate portion C1. The three perforations on the first reinforcing plate 2 are respectively connected to the perforations on the folding plate portion B1, the folding plate portion C1, and the folding plate portion D1 to form three through-holes. One side of the second reinforcing plate 3 is... The first reinforcing plate 2, folding plate B1, folding plate C1, and folding plate D2 are attached to each other, and the other side of the second reinforcing plate 3 is attached to the folding plate C2. Three through holes on the second reinforcing plate 3 are respectively connected to through holes on folding plate B2, folding plate C2, and folding plate D2 to form three through-pass channels. Six connecting components 4 are correspondingly arranged with the six through-pass channels, so that the first reinforcing plate 2, folding plate B1, folding plate C1, and folding plate D1 are connected together, and the second reinforcing plate 3, folding plate B2, folding plate C2, and folding plate D2 are connected together. By adding the first reinforcing plate 2 and the second reinforcing plate 3, the structure of folding plate C1 and folding plate C2 is made more stable, preventing deformation of folding plate C1 and folding plate C2 due to sand pressure.

[0049] like Figure 3As shown, the connecting component 4 includes a first clamping member 41 and a second clamping member 42. The first clamping member 41 is a long strip structure, and a clamping head 411 and a toothed section 412 are sequentially formed along its length. The second clamping member 42 has a fitting hole and a toothed section. The second clamping member 42 is slidably fitted onto the toothed section 412 of the first clamping member 41 through the fitting hole. The toothed section 412 cooperates with the first clamping member 41 so that the first clamping member 41 can only slide unidirectionally toward the clamping head 411, and a clamping and fixing space is formed between the second clamping member 42 and the clamping head 411. Correspondingly, the toothed sections 412 of the six connecting components 4 respectively pass through... The first reinforcing plate 2 and the folded plate portion B1 are placed in the six through-channels, such that the first reinforcing plate 2 and the folded plate portion C1 are clamped in the clamping and fixing space of the connecting component 4, the first reinforcing plate 2 and the folded plate portion D1 are clamped in the clamping and fixing space of the connecting component 4, the second reinforcing plate 3 and the folded plate portion B2 are clamped in the clamping and fixing space of the connecting component 4, the second reinforcing plate 3 and the folded plate portion C2 are clamped in the clamping and fixing space of the connecting component 4, and the second reinforcing plate 3 and the folded plate portion D2 are clamped in the clamping and fixing space of the connecting component 4. This design makes the installation and fixing of the first reinforcing plate 2 and the second reinforcing plate 3 more convenient.

[0050] The lengths of folded edges L1 and L2 are longer than those of folded edges L3 and L4, the lengths of folded edges L11 and L12 are correspondingly longer than those of folded edges L51 and L52, and the lengths of folded edges L21 and L22 are correspondingly longer than those of folded edges L41 and L42. This design ensures that the packaging box closes smoothly when switched to the closed state.

[0051] The outer contour of the cross-section of the toothed segment 412 is rectangular, and the through hole is a rectangular hole that matches the outer contour of the cross-section of the toothed segment 412. The first clamping member 41 and the second clamping member 42 are made of plastic. With this design, the toothed segment 412 is circumferentially positioned by the through hole. When disassembling the connecting assembly 4, by rotating the clamping head 411 of the first clamping member 41, the clamping head 411 and the toothed segment 412 break apart due to relative rotation, so that the connecting assembly 4 can be quickly disassembled and detached from the packaging box.

[0052] A waterproof membrane layer is provided on one or both sides of the folding panel 1. When the packaging box is in the unfolded state, the waterproof membrane layer can prevent pet urine in the sand storage space from seeping out of the folding panel 1 into the external environment.

[0053] Example 2

[0054] like Figures 4 to 6This is a packaging box that can transform into a sand tray, as described in Embodiment 2. The difference between Embodiment 2 and Embodiment 1 is that this embodiment does not include the first and second reinforcing plates; three perforations are formed on each of the folding portions B1, B2, D1, and D2 of the folding plate 1, and one perforation is formed on each of the folding portions A1, A2, C1, C2, E1, and E2 of the folding plate 1; after switching the packaging box to the unfolded state, it is divided along the folded edge L2 or L3 by hand or using a tool. In this embodiment, the packaging box is divided along the folded edge L2, thus splitting the packaging box into a first shell and... The second housing has the connecting plate portion A, connecting plate portion B, folding plate portion A1, folding plate portion A2, folding plate portion B1 and folding plate portion B2 formed on the first housing. The connecting plate portion A, connecting plate portion B, folding plate portion B1 and folding plate portion B2 enclose and form a sliding channel. The second housing has the connecting plate portion C, connecting plate portion D, connecting plate portion E, folding plate portion C1, folding plate portion C2, folding plate portion D1, folding plate portion D2, folding plate portion E1 and folding plate portion E2 formed on the first housing. The second housing is slidably stacked in the sliding space of the first housing. The second housing and the first housing enclose and form a box-shaped container with an opening at the top. The second housing switches between state one, state two and state three by sliding.

[0055] In state one: the connecting plate C, the folding plate C1, and the folding plate C2 of the second housing are in the sliding space. The folding plate D1 of the second housing abuts against the folding plate B1 of the first housing, and the folding plate D2 of the second housing abuts against the folding plate B2 of the first housing. The perforation on the folding plate C1 and one of the perforations on the folding plate B1 are connected to form a through-passage. The perforation on the folding plate C2 and one of the perforations on the folding plate B2 are connected to form a through-passage. The two connecting components 4 are respectively inserted into the two through-passages, so that the folding plate C1 and the folding plate B1 are clamped in the clamping and fixing space of the connecting component 4, and the folding plate C2 and the folding plate B2 are clamped in the clamping and fixing space of the connecting component 4.

[0056] In state two: the connecting plate C, folding plate C1, and folding plate C2 of the second housing are in the sliding space; the connecting plate D, folding plate D1, and folding plate D2 of the second housing are partially in the sliding space; the folding plate C1 of the second housing abuts against the folding plate A1 of the first housing; the folding plate C2 of the second housing abuts against the folding plate A2 of the first housing; the perforation on folding plate C1 and one of the perforations on folding plate B1 connect to form a through-pass channel; the perforation on folding plate C2 and one of the perforations on folding plate B2 connect to form a through-pass channel; one of the perforations on folding plate D1 and the folding plate... One of the perforations on B1 connects to form a through-passage, and one of the perforations on the folded plate part D2 connects to one of the perforations on the folded plate part B2 to form a through-passage. The four connecting components 4 are respectively inserted into the four through-passages, so that the folded plate parts C1 and B1 are clamped in the clamping and fixing space of the connecting component 4, the folded plate parts C2 and B2 are clamped in the clamping and fixing space of the connecting component 4, the folded plate parts D1 and B1 are clamped in the clamping and fixing space of the connecting component 4, and the folded plate parts D2 and B2 are clamped in the clamping and fixing space of the connecting component 4.

[0057] In state three: the connecting plate C, folding plate C1, and folding plate C2 of the second shell are in the sliding space; the connecting plate D, folding plate D1, and folding plate D2 of the second shell are partially in the sliding space; folding plate C1 and folding plate C2 of the second shell abut against the connecting plate A of the first shell; the perforations on folding plate C1, folding plate A1, and one of the perforations on folding plate B1 connect to form a through-pass channel; the perforations on folding plate C2, folding plate A2, and folding plate B2 connect to form a through-pass channel; one of the perforations on folding plate D1 and the other of the perforations on folding plate B1 connect to form a through-pass channel. A through hole is connected to form a through channel. One through hole on the folded plate part D2 and one through hole on the folded plate part B2 are connected to form a through channel. The four connecting components 4 are respectively inserted into the four through channels, so that the folded plate parts C1, A1, and B1 are clamped in the clamping and fixing space of the connecting component 4, the folded plate parts C2, A2, and B2 are clamped in the clamping and fixing space of the connecting component 4, the folded plate parts D1 and B1 are clamped in the clamping and fixing space of the connecting component 4, and the folded plate parts D2 and B2 are clamped in the clamping and fixing space of the connecting component 4.

[0058] This design allows for adjustment of the size of the packaging box that makes up the box by adjusting the stacking position of the second shell relative to the first shell, thus adapting to different usage scenarios.
