Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging materials, and more specifically to a flexible reusable packaging device suitable for packaged products. Background Technology
[0002] Currently, reusable packaging primarily uses rigid materials, offering mostly fixed, restrained protection for the product. Other packaging uses loose, unrestrained materials. Flexible materials are only used in areas of direct contact with the product, and to maintain product stability, most are made of high-rigidity flexible materials such as polyurethane, rubber, and EVA with a hardness of 70 degrees or higher. However, this protective method is not suitable for some inner-packaged products. Since most inner-packaged products are relatively fragile and should not directly contact the protective materials inside the reusable packaging, they are often first protected with cardboard boxes and pearl cotton before being placed in reusable packaging.
[0003] With increasing public awareness of environmental protection, users are paying more and more attention to the environmental friendliness of packaging. Taking LED strips as an example of packaged products, in the promotion of reusable packaging, considering the fragility of LED strip products, the original cardboard inner packaging is still retained, only the wooden outer packaging is replaced. Nowadays, LED strip packaging can no longer meet the growing demand for green packaging.
[0004] Therefore, adhering to the principle of green packaging for reusable products, and providing reliable protection for the products in order to reduce environmental pollution and resource consumption, it is necessary to develop a better packaging device. Utility Model Content
[0005] To address the aforementioned issues, this invention provides a flexible reusable packaging device suitable for packaged products. This device uses flexible materials to protect and limit the contents of the packaged products, and is combined with reusable packaging to achieve green packaging of packaged products while providing reliable protection. It also facilitates the handling of packaged products, reduces environmental pollution and resource consumption, and lowers the cost of disposable cardboard boxes and auxiliary materials.
[0006] According to one aspect of the present invention, a flexible reusable packaging device suitable for packaged products is provided, comprising:
[0007] The base frame includes a lower frame, a bottom sealing plate, a lower support column, and a gas spring. The lower frame is a rectangular frame with column assemblies at the four corners. The bottom sealing plate is laid inside the lower frame. The lower end of the lower support column is rotatably mounted on the column assembly. The lower support column has a waist-shaped through hole. One end of the gas spring is hinged to the lower frame, and the other end of the gas spring passes through the waist-shaped through hole and is hinged to the upper end of the lower support column.
[0008] The upper frame includes an upper frame, a rainproof cloth, upper support columns, and support rods. The upper frame is a rectangular frame, and the rainproof cloth covers the upper frame. The upper ends of the upper support columns are rotatably installed at the four corners of the upper frame. One end of the support rod is hinged to the upper frame, and the other end of the support rod is connected to the lower end of the upper support column through a pin. The lower end of the upper support column is hinged to the upper end of the lower support column.
[0009] A canvas assembly, wherein at least one canvas assembly is provided, each canvas assembly includes a canvas bag, and the bottom and top of the canvas bag are provided with long poles to support the canvas bag. The long pole at the bottom of the canvas bag is installed on the lower frame, and the long pole at the top of the canvas bag is installed on the upper frame.
[0010] When the flexible reusable packaging device is folded, the pin is pulled out, the gas spring retracts, the hinge of the lower support column and the upper support column bends, the column assembly presses against the four corners of the upper frame, and the upper frame folds above the base frame.
[0011] Thus, the upper and lower frames are spliced together to form a rigid frame, and flexible canvas bags are placed inside the rigid frame. The canvas bags provide flexible restraint for the products inside. This packaging device is not a disposable auxiliary material and can be recycled. When the pin is pulled out and the gas spring is contracted, the hinge joint between the lower support column and the upper support column bends inward, and the upper frame descends as a whole, achieving folding. Because the frame is rigid, it can be stacked before and after folding, which is convenient for the transportation and storage of full and empty boxes.
[0012] In some embodiments, the support column assembly includes a support column plate and a mounting plate. The support column plate is vertically arranged, and the mounting plate is horizontally fixed to the support column plate. The mounting plate is used to connect to the adjacent lower frame. The lower support column is rotatably inserted into the support column plate, and the side of the support column plate facing the gas spring is open. As a result, when the gas spring contracts, it pulls the lower support column to rotate, and the upper end of the lower support column faces the lower frame. The gas spring is housed below the lower support column and in a waist-shaped through hole, ensuring that the lower support column does not affect the descent of the upper frame after folding.
[0013] In some embodiments, a reinforcing plate is provided at the upper end of the lower support column. The upper and lower ends of the reinforcing plate are open, while the side of the reinforcing plate facing the gas spring is closed. The reinforcing plate is located at the hinge point of the upper and lower support columns. The lower end of the reinforcing plate is connected to the upper support column, and the upper end of the reinforcing plate is provided with an insertion hole. When the flexible recirculating packaging device is unfolded, the pin is inserted into the insertion hole to connect the support rod to the upper support column. When the flexible recirculating packaging device is folded, a lower support point is provided on the lower frame, and an upper support point is provided on the upper frame. The closed surface of the reinforcing plate abuts against the lower support point, and the upper support column abuts against the upper support point. Thus, when the packaging device is unfolded, the reinforcing plate can reinforce the connection point between the upper and lower support columns. When the packaging device is folded, the upper support point, upper support column, lower support column, reinforcing plate, and lower support point can support the upper and lower frames, ensuring that the upper frame remains horizontal after folding.
[0014] In some embodiments, the pin is a toggle pin, which is connected to the support rod via a chain. The upper frame has a pin hole, and the pin is pulled out of the pin hole and then inserted into it. Thus, the toggle pin is connected to the support rod via the chain, which prevents loss. The packaging device is assembled as a whole, without any separate parts, avoiding the problem of lost parts, and each part can be replaced individually.
[0015] In some embodiments, a limiting plate is provided at the upper end of the upper support column. When the flexible recirculating packaging device is unfolded, the limiting plate abuts against the upper frame; when the flexible recirculating packaging device is folded, the limiting plate abuts against the lower support column. Thus, the limiting plate can prevent instability between the upper support column and the upper frame after unfolding, and after folding, the limiting plate serves to support both the upper and lower support columns.
[0016] In some embodiments, the canvas bag has multiple internal layers, an exit on one side with a cover attached to the exit, and a snap fastener connected to the cover. A metal ring that engages with the snap fastener is located on the outside of the canvas bag. This layered structure allows for the protection of the contents by placing them in separate layers, and the exit on one side of the canvas bag allows for side loading or unloading of the products.
[0017] In some implementations, one side of the rainproof cloth is fixed to the upper frame with a pressure strip and rivets, while the other three sides are connected to the upper frame via buckles. Thus, the rainproof cloth is fixedly mounted on the upper frame, and the other three sides can be opened for easy lifting.
[0018] In some embodiments, a handle is provided at the top of the upper frame, with the handle distributed on at least two opposite sides of the upper frame, and fork sleeves are provided at the bottom of the lower frame, with at least two sleeves on each opposite side. Thus, the handle facilitates operation, and the fork sleeves guide the fork teeth and ensure safety.
[0019] Compared with the prior art, the beneficial effects of this utility model are:
[0020] (i) This flexible recyclable packaging device uses canvas bags made of flexible material to flexibly constrain the inner products. The base frame and upper frame made of steel structure splicing form a frame to support the flexible canvas bags, which has good protection for fragile inner products such as light strips. The inner products can be directly packed without inner packaging, which solves the problem of the limited applicability of recyclable packaging to inner products. This packaging device has strong versatility and can be used for different types and specifications of inner products. It can be used as an integrated packaging for storage and transportation of inner products.
[0021] (ii) The packaging device adopts an overall folding structure with gas spring auxiliary support, which facilitates unfolding and folding operations. The internal canvas bag is flexible and does not interfere with the folding. It has good stability before and after folding and can be stacked before and after folding, which greatly reduces the transportation cost of full and empty boxes. All packaging materials can be recycled and no disposable auxiliary waste such as cardboard boxes and bubble bags is generated, which reduces resource consumption, lowers packaging costs, and has a positive effect on environmental protection.
[0022] (iii) The canvas bag has a layered internal structure, which makes high space utilization and allows for packing or unpacking from the side. The side exit of the canvas bag is secured with buckles to prevent the contents from spilling out during transportation.
[0023] (iv) The packaging device is assembled into a whole without any separate parts, thus avoiding the problem of missing parts. Moreover, each part can be replaced individually, which greatly reduces the cost and complexity of packaging maintenance. Attached Figure Description

[0035] The present invention will be further described below with reference to specific embodiments.
[0036] like Figure 1 , 2 As shown in Figure 9, a flexible recyclable packaging device suitable for internal products according to one embodiment of the present invention includes a base frame 1, an upper frame 2, and a canvas assembly 3. The base frame 1 and the upper frame 2 are assembled together to form an integral steel structure frame, and the canvas assembly 3 is placed inside the steel structure frame.
[0037] like Figures 3 to 5 As shown, the base frame 1 includes a lower frame 11, a bottom sealing plate 13, a lower support column 14, and a gas spring 15. The lower frame 11 is a rectangular frame made of rectangular steel pipes, and the steel pipes are connected at the four right angles by column assemblies 12. The interior of the rectangular frame is reinforced with steel pipes both longitudinally and laterally. The bottom sealing plate 13 is laid inside the lower frame 11 to form a closed bottom surface. Fork sleeves 112 are installed at the bottom of the lower frame 11. The fork sleeves 112 are distributed on at least two opposite sides of the lower frame 11, with at least two on one side. In this way, the fork sleeves 112 serve to guide the fork teeth and ensure safety. The lower support column 14 is mainly made of rectangular steel pipe. The lower end of the lower support column 14 is rotatably mounted on the column assembly 12. The lower support column 14 has a waist-shaped through hole 141. One end of the gas spring 15 is hinged to the lower frame 11, and the other end of the gas spring 15 passes through the waist-shaped through hole 141 and is hinged to the upper end of the lower support column 14.
[0038] like Figures 6 to 8As shown, the upper frame 2 includes an upper frame 21, a rainproof tarpaulin 22, upper support columns 23, and support rods 24. The upper frame 21 is a rectangular frame made of rectangular steel pipes and covered with the rainproof tarpaulin 22. Handles 213 are welded to the top of the upper frame 21, and the handles 213 are distributed on at least two opposite sides of the upper frame 21, serving to facilitate operation. The top of the upper support column 23 has a sealing plate 4, which serves to provide support and prevent water from entering. The upper end of the upper support column 23 has a pivot plate 5 232, which, along with bolts, allows the upper end of the upper support column 23 to be rotatably installed at the four corners below the upper frame 21. The upper end of the lower support column 14 has a pivot plate 143, and the lower end of the upper support column 23 has a pivot plate 233. The lower end of the upper support column 23 and the upper end of the lower support column 14 are hinged together by bolts through the pivot plates 143 and 233. One end of the support rod 24 is hinged to the upper frame 21. The lower end of the upper support column 23 has a hole 234 for installing a pin 25. The other end of the support rod 24 is connected to the lower end of the upper support column 23 by inserting a pin 25 into the hole 234.
[0039] like Figure 10 As shown, at least one set of canvas assemblies 3 is provided, and the number or size of the canvas assemblies 3 is determined according to the size of the steel structure frame. In this embodiment, there are three sets of canvas assemblies 3. Each set of canvas assemblies 3 includes a canvas bag 31, with long rods penetrating both the bottom and top of the canvas bag 31. The lower frame 11 has a first fixing member 17, and the upper frame 21 has a second fixing member 26. The two ends of the long rod at the bottom of the canvas bag 31 are installed on the first fixing member 17 of the lower frame 11, and the long rod at the top of the canvas bag 31 is installed on the second fixing member 26 of the upper frame 21 to support the canvas bag 31.
[0040] When the flexible reusable packaging device is folded, the pin 25 is pulled out, the gas spring 15 is contracted, the hinge of the lower support column 14 and the upper support column 23 is bent, the column assembly 12 is pressed against the four corners of the upper frame 21, and the upper frame 2 is folded above the base frame 1.
[0041] like Figure 4As shown, the column assembly 12 specifically includes a column plate 121 and a mounting plate 122. The column plate 121 is vertically positioned and is made of bent and welded steel plate. The side of the column plate 121 facing the gas spring 15 has an open opening 1211 to facilitate the folding of the lower support column 14. The mounting plate 122 is also made of bent steel plate and is horizontally welded and fixed to the column plate 121. The mounting plate 122 connects the steel pipes on adjacent sides of the lower frame 11 and is fixed with bolts. An ankle 123 is welded to the bottom of the column plate 121, and foot pads 124 are bolted to the bottom of the ankle 123 to support and protect the ground. An angle bracket 125 is welded between the column plate 121 and the mounting plate 122 for reinforcement. Furthermore, a pivot plate 126 is welded to the mounting plate 122, and a pivot plate 142 is welded to the lower end of the lower support column 14. The lower support column 14 is inserted into the column plate 121, and the pivot plate 126 and the pivot plate 142 are connected by bolts, realizing a rotatable connection between the lower support column 14 and the column plate 121. When the gas spring 15 retracts, it pulls the upper support column 23 to rotate, and the upper end of the lower support column 14 turns towards the lower frame 11. The gas spring 15 is housed below the lower support column 14 and in the waist-shaped through hole 141, ensuring that the lower support column 14 does not affect the descent of the upper frame 2 after folding.
[0042] like Figure 5 As shown, a reinforcing plate 16 is installed at the upper end of the lower support column 14. The upper and lower ends of the reinforcing plate 16 are open, and the side of the reinforcing plate 16 facing the gas spring 15 is a closed surface 161. The reinforcing plate 16 is located at the hinge point between the upper support column 23 and the lower support column 14, and the reinforcing plate 16 serves as a stop and auxiliary reinforcement. An insertion hole 162 is provided at the upper end of the reinforcing plate 16.
[0043] When the flexible reusable packaging device unfolds, the pin 25 is inserted into the insertion hole 162 of the reinforcing plate 16 and the hole 234 of the upper support column 23, thereby connecting the support rod 24 to the upper support column 23. The upper surface of the lower frame 11 has a lower support point 111, and the lower support point 111 has a sealing plate 4. Figure 3 (As shown). The lower surface of the upper frame 21 has an upper support point 211, and the upper support point 211 has a sealing plate (as shown). Figure 7 As shown). Figure 2 As shown, when the flexible recyclable packaging device is folded, the closed surface 161 of the reinforcing plate 16 abuts against the lower support point 111, and the upper support column 23 abuts against the upper support point 211.
[0044] When the packaging device is unfolded, the reinforcing plate 16 can reinforce the connection point between the upper support column 23 and the lower support column 14. When the packaging device is folded, the upper support point 211, the upper support column 23, the lower support column 14, the reinforcing plate 16, and the lower support point 111 can support the upper frame 21 and the lower frame 11, so that the upper frame 21 remains horizontal after folding.
[0045] In this embodiment, as Figure 6 As shown, pin 25 is a toggle pin, which is connected to support rod 24 via chain 251. The upper frame 21 has a pin hole 212. When folding is required, pin 25 is pulled out of insertion hole 162 and inserted into pin hole 212. The toggle pin is connected to support rod 24 via chain 251, serving to prevent loss.
[0046] A limiting plate 231 is welded to the upper end of the upper support column 23. When the flexible recyclable packaging device is unfolded, the limiting plate 231 abuts against the upper frame 21. When the flexible recyclable packaging device is folded, the limiting plate 231 abuts against the lower support column 14. The limiting plate 231 can prevent the connection between the upper support column 23 and the upper frame 21 from being unstable after unfolding. After folding, the limiting plate 231 serves to support the upper support column 23 and the lower support column 14.
[0047] One side of the rainproof cloth 22 is placed on one side of the upper frame 21, held down by a pressure strip 221, and fixed to the upper frame 21 with rivets (not shown). Three sides of the rainproof cloth 22 are connected to the upper frame 21 via barbed fasteners. Specifically, the barbed side is fixed to the frame with rivets, and the loose side is fixed to the rainproof cloth 22. The rainproof cloth 22 is fixedly installed on the upper frame 21, and the other three sides can be opened for easy lifting.
[0048] In canvas group 3, each canvas bag 31 is independent, and the interior of each canvas bag 31 can be divided into multiple layers, resulting in high space utilization. For example... Figure 11 As shown, one side of the canvas bag 31 is fully sewn shut, while the other side, designated as an exit, is single-sided sewn shut. A cover 32 is located at the exit, with snap fasteners 34 attached to it. A metal ring 35, which engages with the snap fasteners 34, is sewn onto the outside of the canvas bag 31. The layered structure allows for layered placement and protection of the contents. The exit on one side of the canvas bag 31 allows for side loading or unloading of the products. Snap fasteners 34 secure the side exit of the canvas bag 31 to prevent the contents from spilling out during transport.
[0049] This flexible reusable packaging device uses canvas bags 31 made of flexible material to flexibly constrain the contents. A base frame 1 and an upper frame 2, constructed from steel structures, form a rigid frame supporting the flexible canvas bags 31. This provides good protection for fragile products such as LED strips. The contents can be directly packed into boxes without inner packaging, solving the problem of limited applicability of reusable packaging systems to different products. This packaging device is highly versatile and suitable for various types and specifications of contents, serving as an integrated storage and transportation packaging solution.
[0050] The packaging device adopts an overall folding structure, with gas spring 15 for auxiliary support, which facilitates unfolding and folding operations. The internal canvas bag 31 is flexible and does not interfere with the folding. It has good stability before and after folding, and can be stacked before and after folding, which greatly reduces the transportation cost of full and empty boxes.
[0051] The packaging unit is assembled as a single unit with no separate parts, thus avoiding the loss of components. Furthermore, each part can be replaced individually, significantly reducing the cost and complexity of packaging maintenance. All packaging materials are recyclable, and no disposable auxiliary waste such as cardboard boxes and bubble wrap is generated, reducing resource consumption, lowering packaging costs, and contributing positively to environmental protection.
[0052] The above descriptions are merely some embodiments of this utility model. It should be noted that those skilled in the art can make other modifications and improvements without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
