Description

Technical Field

[0001] This utility model relates to the field of folding paper box technology, and more specifically, to a folding paper tray box. Background Technology

[0002] Currently, paper packaging materials are widely used in various products, especially in the food industry, such as packaging for powdered products like milk powder and nutritional powder.

[0003] In related technologies, during the packaging of powder-based strip products, to enhance the consumer experience, orderly boxing is often required, typically achieved by dividing the internal space of the cardboard box into several areas using inner trays. However, due to the fluctuation in the particle size of powder products, the thickness of the strip packaging bags will also vary, especially for inflatable strip packaging bags. If the inflation volume is too large, the designed cardboard box size will be insufficient; if the inflation volume is too small, the reserved packaging space will be too large, making it impossible to ensure the orderly arrangement of the strip packaging bags.

[0005] To achieve the above objectives, according to one aspect of the present invention, a folding paper tray box is provided for holding packaging bags, comprising: a base plate; a first side plate, a second side plate, and a third side plate, sequentially arranged and all connected to the base plate, the first side plate and the third side plate being arranged opposite to each other, and a receiving cavity being formed between the first side plate, the second side plate, the third side plate and the base plate; a first connecting plate and a second connecting plate, the first side of the first connecting plate being connected to the top of the first side plate, the first side of the second connecting plate being connected to the top of the third side plate, the first connecting plate extending toward the third side plate, and the second connecting plate extending toward the first side plate; a first limiting plate, the first side of the first limiting plate being connected to the second side of the first connecting plate and extending toward the base plate, the second end of the first limiting plate being a first free side; and a second limiting plate, the first side of the second limiting plate being connected to the second side of the second connecting plate and extending toward the base plate, the second end of the second limiting plate being a second free side.

[0006] The distance between the first connecting plate and the second connecting plate is W1, and the total dimension of the packaging bag from the first connecting plate to the second connecting plate is T, where 0.8≤W1 / T≤1.

[0007] The distance between the first connecting plate and the second connecting plate is W1, the width of the first connecting plate is W2, the width of the second connecting plate is W3, and the total dimension of the packaging bag from the first connecting plate to the second connecting plate is T, where 1 < (W1 + W2 + W3) / T ≤ 1.4.

[0008] The folding paper tray also includes a third connecting plate, which is connected to the second side plate, the first connecting plate, and the second connecting plate.

[0009] The folding paper tray also includes a fourth connecting plate, the first end of which is connected to the side of the third connecting plate away from the second side plate, and the second end of the fourth connecting plate extends toward the bottom plate.

[0010] The folding paper tray also includes a fifth connecting plate. The first end of the fifth connecting plate is connected to the second end of the fourth connecting plate. The fifth connecting plate is connected to the side of the bottom plate away from the second side plate. The fifth connecting plate is fitted to the bottom plate.

[0011] The folding paper tray also includes a stop structure, which is connected to the side of the base plate away from the second side plate.

[0012] The stop structure includes a first stop plate and a second stop plate. The first stop plate is connected between the base plate and the first connecting plate, and the second stop plate is connected between the base plate and the second connecting plate.

[0013] In the direction from the base plate to the first connecting plate, the distance between the first stop plate and the second stop plate increases.

[0014] The projection of the first limiting plate on the second side plate is located within the range of the first stop plate on the second side plate, and / or the projection of the second limiting plate on the second side plate is located within the range of the second stop plate on the second side plate.

[0015] Applying the technical solution of this utility model, a first side plate, a second side plate, and a third side plate are sequentially arranged and all connected to a bottom plate. The first and third side plates are arranged opposite to each other, forming a receiving cavity between the first, second, and third side plates and the bottom plate. A first connecting plate is connected to the top of the first side plate, and a second connecting plate is connected to the top of the third side plate. A first limiting plate is connected to the first connecting plate, and a second limiting plate is connected to the second connecting plate.

It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0029] like Figures 1 to 4 as well as Figure 7 As shown, in this embodiment, the folding paper tray box, used to hold packaging bags, includes: a base plate 10, a first side plate 21, a second side plate 22, a third side plate 23, a first connecting plate 31, a second connecting plate 32, a first limiting plate 41, and a second limiting plate 42. The first side plate 21, the second side plate 22, and the third side plate 23 are sequentially arranged and all connected to the base plate 10. The first side plate 21 and the third side plate 23 are arranged opposite to each other, forming a receiving cavity 24 between the first side plate 21, the second side plate 22, the third side plate 23, and the base plate 10. The first side of the first connecting plate 31 is connected to the top of the first side plate 21, and the first side of the second connecting plate 32 is connected to the top of the third side plate 23. The first connecting plate 31 extends toward the third side plate 23, and the second connecting plate 32 extends toward the first side plate 21. The first side of the first limiting plate 41 is connected to the second side of the first connecting plate 31 and extends toward the base plate 10. The second end of the first limiting plate 41 is a first free side. The first side of the second limiting plate 42 is connected to the second side of the second connecting plate 32 and extends to the base plate 10. The second end of the second limiting plate 42 is the second free side.

[0030] Applying the technical solution of this utility model, the first side plate 21, the second side plate 22, and the third side plate 23 are sequentially arranged and all connected to the bottom plate 10. The first side plate 21 and the third side plate 23 are arranged opposite to each other, forming a receiving cavity 24 between the first side plate 21, the second side plate 22, the third side plate 23, and the bottom plate 10. The first connecting plate 31 is connected to the top of the first side plate 21, and the second connecting plate 32 is connected to the top of the third side plate 23. The first limiting plate 41 is connected to the first connecting plate 31, and the second limiting plate 42 is connected to the second connecting plate 32. Through the above arrangement, the packaging bag can be placed in the receiving cavity 24. At the same time, the first limiting plate 41 and the second limiting plate 42 can limit the packaging bag, that is, the first limiting plate 41 and the second limiting plate 42 can push the packaging bag, thereby making the position of the packaging bag more stable. That is, under the action of the first limiting plate 41 and the second limiting plate 42, the packaging bag can be arranged in an orderly manner. Therefore, the technical solution of this application effectively solves the problem in the related technology that paper trays are difficult to arrange in an orderly manner for strip packaging bags.

[0031] like Figure 3 As shown, in this embodiment, the distance between the first connecting plate 31 and the second connecting plate 32 is W1, and the total dimension of the packaging bag from the first connecting plate 31 to the second connecting plate 32 is T, where 0.8 ≤ W1 / T ≤ 1. This ratio ensures that the first limiting plate 41 and the second limiting plate 42 can effectively limit the packaging bag even when its thickness fluctuates, without affecting the packaging effect due to excessive tightness or looseness. That is, the packaging bag can be stably maintained in a predetermined position within the receiving cavity 24, maintaining a good arrangement even when subjected to vibration during transportation, preventing movement and collision of the packaging bag within the receiving cavity 24, and improving the protective performance of the folded paper tray.

[0032] Specifically, in this embodiment, W1 / T = 0.9. In other embodiments, the ratio of W1 / T can be 0.81, 0.82, 0.83, 0.84, 0.85, 0.86, 0.87, 0.88, 0.89, 0.91, 0.92, 0.93, 0.94, 0.95, 0.96, 0.97, 0.98, 0.99, or other ratios.

[0033] like Figure 3As shown, in this embodiment, the distance between the first connecting plate 31 and the second connecting plate 32 is W1, the width of the first connecting plate 31 is W2, the width of the second connecting plate 32 is W3, and the total dimension of the packaging bag from the first connecting plate 31 to the second connecting plate 32 is T, where 1 < (W1 + W2 + W3) / T ≤ 1.4. This configuration, by increasing the ratio of the total widths of the first connecting plate 31 (W2), the second connecting plate 32 (W3), and the distance between the first connecting plate 31 and the second connecting plate 32 (W1), to the total dimension T of the packaging bag, ensures that the folding paper tray box can still provide sufficient restraint and support when the thickness of the packaging bag fluctuates significantly, while maintaining the stability and strength of the overall structure.

[0034] Specifically, in this embodiment, W1+W2+W3 / T=1.2. Of course, in other embodiments, the above ratio can also be 1.05, 1.1, 1.15, 1.25, 1.3, 1.35 or other ratios.

[0035] like Figures 1 to 3 as well as Figure 5 As shown, in this embodiment, the folding paper tray also includes a third connecting plate 51, which is connected to the second side plate 22, the first connecting plate 31, and the second connecting plate 32. The third connecting plate 51 increases the structural strength of the folding paper tray, ensuring that the overall structure of the folding paper tray will not deform due to stress during the folding process, thus improving the stability and reliability of the folding paper tray.

[0036] like Figures 1 to 3 as well as Figures 5 to 7 As shown, in this embodiment, the folding paper tray also includes a fourth connecting plate 52. The first end of the fourth connecting plate 52 is connected to the side of the third connecting plate 51 away from the second side plate 22, and the second end of the fourth connecting plate 52 extends toward the bottom plate 10. The fourth connecting plate 52 further enhances the structural strength of the folding paper tray and provides additional support for the orderly arrangement of the packaging bags, ensuring the stability and safety of the packaging bags within the folding paper tray.

[0037] Specifically, the width of the fourth connecting plate 52 gradually increases from the direction closest to the base plate 10 to the direction furthest from the base plate 10.

[0038] like Figures 1 to 3 as well as Figures 5 to 7As shown, in this embodiment, the folding paper tray box further includes a fifth connecting plate 53. The first end of the fifth connecting plate 53 is connected to the second end of the fourth connecting plate 52, and the fifth connecting plate 53 is connected to the side of the bottom plate 10 away from the second side plate 22. The fifth connecting plate 53 is fitted snugly to the bottom plate 10. The provision of the fifth connecting plate 53 not only enhances the connection strength between the fourth connecting plate 52 and the bottom plate 10, but also provides additional constraints for the orderly arrangement of the packaging bags, ensuring the stability and safety of the packaging bags within the folding paper tray box.

[0039] Specifically, the fifth connecting plate 53 can limit the position of the fourth connecting plate 52, thereby making the position of the fourth connecting plate 52 more stable.

[0040] like Figure 1 , Figure 2 , Figure 4 as well as Figure 7 As shown, in this embodiment, the folding paper tray also includes a stop structure 60, which is connected to the side of the bottom plate 10 away from the second side plate 22. The stop structure 60 provides additional restraint for the packaging bag, ensuring the stability and safety of the packaging bag within the folding paper tray, while preventing the packaging bag from moving or colliding within the folding paper tray.

[0041] like Figure 1 , Figure 2 , Figure 4 as well as Figure 7 As shown, in this embodiment, the stop structure 60 includes a first stop plate 61 and a second stop plate 62. The first stop plate 61 is connected between the base plate 10 and the first connecting plate 31, and the second stop plate 62 is connected between the base plate 10 and the second connecting plate 32. There is a gap between the first stop plate 61 and the second stop plate 62. The structure of the first stop plate 61 and the second stop plate 62 is relatively simple, and they can provide effective restraint for the packaging bag, ensuring the stability and safety of the packaging bag in the folding paper tray box, while preventing the product from moving and colliding within the folding paper tray box.

[0042] like Figure 1 , Figure 2 , Figure 4 as well as Figure 7 As shown, in this embodiment, the distance between the first stop plate 61 and the second stop plate 62 is increased in the direction from the base plate 10 to the first connecting plate 31. This arrangement makes it easier to remove the packaging bag.

[0043] like Figure 1 , Figure 2 , Figure 4 as well as Figure 7As shown, in this embodiment, the projection of the first limiting plate 41 on the second side plate 22 is located within the range of the first stop plate 61 on the second side plate 22, and the projection of the second limiting plate 42 on the second side plate 22 is located within the range of the second stop plate 62 on the second side plate 22. This design ensures that the first limiting plate 41 and the second limiting plate 42 can effectively cooperate with the first stop plate 61 and the second stop plate 62, providing all-around limiting and support for the packaged product, ensuring the stability and safety of the packaging bag within the folding paper tray box.

[0044] The folding paper tray box in this embodiment, through the design of the first limiting plate 41 and the second limiting plate 42, can adapt to fluctuations in the thickness of the packaging bag within a certain range, ensuring the orderly arrangement of the packaging bags and improving the stability of the packaging. The principle of this design is to utilize the elastic characteristics of the first limiting plate 41 and the second limiting plate 42; that is, the first limiting plate 41 and the second limiting plate 42 can automatically adjust the limiting force according to changes in the thickness of the packaging bag, thereby ensuring the stability and safety of the packaging bag within the folding paper tray box. The packaging bag can be held more stably in the predetermined position within the folding paper tray box, maintaining a good packaging condition even when the thickness of the packaging bag fluctuates, preventing the product from moving or colliding within the box, and improving the protective performance of the folding paper tray box.

[0045] The design of the toothed lines at the rounded corners of the first limiting plate 41 and the second limiting plate 42 facilitates the folding and forming of the folding paper tray, while effectively avoiding the risk of paper tearing, thus improving production efficiency and yield. Specifically, the toothed lines at the rounded corners of the first limiting plate 41 and the second limiting plate 42 guide the folding and forming of the folding paper tray, preventing paper tearing during the folding process and improving production efficiency and yield. In other words, the folding paper tray can be folded more smoothly during the forming process, avoiding production delays and decreased yield caused by paper tearing.

[0046] The folding paper tray in this embodiment is transported and stored in a flat state, significantly reducing space occupation, lowering transportation costs, and facilitating warehouse management. This design utilizes the folding characteristic of the paper tray, meaning that during transportation and storage, the folding paper tray can be placed in a flat state, significantly reducing space occupation, lowering transportation costs, and facilitating warehouse management.

[0047] The folding paper tray is folded by hand, which is simple and quick to operate, eliminates the need for additional thickened cardboard, saves material costs, and maintains the sturdiness of the folding paper tray.

[0048] In the description of this utility model, it should be understood that "multiple" means a quantity of two or more. Directional terms such as "front, back, up, down, left, right," "horizontal, vertical, perpendicular, horizontal," and "top, bottom" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. These terms are used solely for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of this utility model.
