Abstract
Description
Technical Field
[0001] This utility model relates to the field of storage container technology, and in particular to a highly sealed transparent plastic storage box with a partition layer. Background Technology
[0002] Most plastic storage boxes with dividers commonly found on the market use a grid of slots at the bottom of the box, into which users insert flat dividers to create compartments of different sizes. While this design is widespread, it has several inherent drawbacks:
[0003] First, the slotted structure at the bottom of the box creates numerous cleaning dead zones, making it easy for dust and debris to fall into the slots and difficult to clean, affecting hygiene and appearance. Second, the dividers, which are only fixed by the bottom slots, have poor stability. When the storage box is moved, tilted, or not full, the dividers can easily come loose from the slots and tip over, causing the sorted items to become mixed up, which is inconvenient for users. Third, tiny leakage paths may form between the dividers and the box body, as well as at the seams of the dividers themselves. If the top of the divider interferes with the lid, it may affect the complete closure of the lid, thereby compromising the overall high sealing performance of the storage box, which is detrimental to storage scenarios that require moisture and dust protection.
[0004] Therefore, to address the above issues, a highly sealed transparent plastic storage box with a partition layer is proposed. Through a modular inner liner structure, it achieves stable partitioning, seamless and easy-to-clean box body, and reliable sealing. Utility Model Content
[0005] To overcome the problems of traditional plastic storage boxes with dividers that are difficult to clean, have unstable divider structures, and are not securely sealed during daily use.
[0006] The technical solution of this utility model is: a highly sealed transparent plastic storage box with a partition layer, including a box body and a lid that seals with the edge of the box body; it also includes:
[0007] A separate inner liner independent of the box body and the box lid;
[0008] The inner partition includes a top frame, at least one partition extending downward from the inside of the top frame, and a bottom support structure located in the bottom region of the partition.
[0009] The outer contour shape of the top frame is adapted to the inner wall shape of the box, so that the partition liner can be placed into the box, and the top frame is supported on the inside or above the opening of the box.
[0010] A cleaning gap is formed between the bottom support structure and the inner bottom surface of the box, and / or between the bottom support structure and the bottommost end of the partition plate.
[0011] Preferably, the outer contour shape of the top frame matches the inner wall shape of the box, allowing the entire inner liner to be easily placed into the box like a small, independent basket. When the inner liner is placed in, its top frame is precisely supported on the inner side or above the opening of the box, thus determining the axial position of the inner liner within the box. A gap is intentionally maintained between the bottom support structure and the inner bottom surface of the box, and / or between the bottom support structure and the bottommost end of the partition plate, i.e., a cleaning gap. This gap ensures that there is no tight contact between the bottom of the box and the bottom of the inner liner, fundamentally eliminating the problem of dirt accumulation caused by slots in traditional designs.
[0012] Preferably, the inner partition is an integrally injection-molded plastic frame structure, and the partition plate is fixedly connected to the top frame and the bottom support structure.
[0013] Preferably, the bottom support structure is a mesh grid connected to the bottom of all the partition plates or a grid-like plane composed of multiple transverse connecting ribs.
[0014] Preferably, the inner bottom surface of the box is a completely smooth plane.
[0015] Preferably, when the lid is closed on the box body, the inner surface of the lid presses against or is adjacent to the upper surface of the top edge of the partition liner.
[0016] Preferably, the height of the cleaning gap is 1 mm to 10 mm.
[0017] Preferably, the inner liner is an independent component that can be removed and placed separately from the box body, and the box body and the lid form a complete, highly sealed container.
[0018] The beneficial effects of this utility model are:
[0019] This invention utilizes an integrally molded inner liner to make the divider a fixed structure, eliminating the risk of it falling out and achieving stable separation. The smooth bottom of the box and the hollowed-out inner liner with cleaning gaps prevent dirt from accumulating, improving the ease of cleaning. At the same time, the inner liner module does not interfere with the sealing interface, ensuring the high sealing reliability of the original box. Furthermore, the modular design supports inner liner replacement and overall removal, improving organization and cleaning efficiency. It achieves stable separation, a seamless and easy-to-clean box, and reliable sealing. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0026] Example 1
[0027] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides an embodiment: a highly sealed transparent plastic storage box with a partition layer, including a box body 1 and a box lid 2 that seals with the opening edge of the box body 1; it also includes:
[0028] An inner liner 3 that is separate from the box body 1 and the box lid 2;
[0029] The inner liner 3 includes a top frame 31, at least one partition plate 32 extending downward from the inside of the top frame 31, and a bottom support structure 33 located in the bottom region of the partition plate 32.
[0030] The outer contour shape of the top frame 31 is adapted to the inner wall shape of the box 1, so that the inner liner 3 can be placed inside the box 1, and the top frame 31 is supported on the inside or above the opening of the box 1.
[0031] A cleaning gap is formed between the bottom support structure 33 and the inner bottom surface of the box 1, and / or between the bottom support structure 33 and the bottommost end of the partition plate 32.
[0032] The outer contour of the top frame 31 matches the inner wall shape of the box 1, allowing the entire inner liner 3 to be easily placed inside the box 1 like a small independent basket. When the inner liner is placed inside, its top frame 31 is precisely supported on the inside or above the opening of the box 1, thus determining the axial position of the inner liner in the box. A gap is intentionally maintained between the bottom support structure 33 and the inner bottom surface of the box 1, and / or between the bottom support structure 33 and the bottommost end of the partition plate 32, namely a cleaning gap. This gap ensures that there is no tight contact between the bottom of the box 1 and the bottom of the inner liner, fundamentally eliminating the problem of dirt accumulation caused by slots in traditional designs.
[0033] Furthermore, the inner liner 3 is an integrally injection-molded plastic frame structure, with the partition plate 32 fixedly connected to the top frame 31 and the bottom support structure 33; the partition plate 32 is fixedly connected to the top frame 31 and the bottom support structure 33, without any detachable or movable splicing nodes; this integrally molded structure provides the overall rigidity and structural strength of the inner liner, ensuring that the position of all partition plates 32 is absolutely fixed, preventing tipping or disintegration, and also simplifying the production and assembly process.
[0034] Furthermore, the bottom support structure 33 is a mesh grid connected to the bottom of all the partition plates 32 or a grid-like plane composed of multiple horizontal connecting ribs; the mesh aperture of this grid structure is smaller than that of common small items, which can effectively prevent them from accidentally falling out of the grid; the grid itself has a high permeability, which allows dust and liquid to easily pass through or flow away, and together with the aforementioned cleaning gaps, a balance between leak prevention and easy cleaning is achieved.
[0035] Furthermore, the inner bottom surface of the box 1 is a completely smooth plane without any grooves, protrusions, or dot-shaped positioning posts for inserting the partition plate 32, allowing a cloth or water flow to wipe or rinse the entire bottom surface without obstruction, achieving thorough cleaning.
[0036] Furthermore, when the lid 2 is closed on the box body 1, the inner surface of the lid 2 presses against or is close to the upper surface of the top edge 31 of the inner liner 3; this pressing action further locks the position of the inner liner inside the box, preventing it from shifting during transportation; and since the pressure is applied directly to the inner liner edge rather than transmitted through the partition plate 32, it does not interfere with the uniform pressing of the sealing ring between the lid 2 and the edge of the box body 1, ensuring the original high sealing performance.
[0037] Furthermore, the height of the cleaning gap is between 1mm and 10mm; less than 1mm may cause the gap to malfunction, easily become filled with dirt, or make it impossible for cleaning tools to reach in; greater than 10mm may weaken the support structure 33 for larger items, and may cause small items to slide out of the gap when tilted; a gap within this range can ensure both efficient cleaning ability and a good user experience.
[0038] Furthermore, the inner divider 3 is an independent component that can be removed and placed separately from the box body 1. The box body 1 and the lid 2 together form a complete, highly sealed container. The box body 1 and the lid 2 themselves can form a complete, highly sealed storage container, while the inner divider 3 is an optional, enhanced plug-in that allows users to quickly change the inner divider layout according to the different items to be stored. When a large number of items need to be organized, the entire inner divider can be removed and operated on the workbench. When cleaning, the smooth box body 1 and the perforated inner divider can be rinsed separately, which is extremely convenient.
[0039] When working, the user first selects an independent partitioned inner liner 3 with a suitable partition layout according to the storage needs; the inner liner is then placed directly into the box 1 with a smooth bottom surface, and the inner liner is naturally suspended inside the box by its top frame 31.
[0040] Place the items to be sorted into the various compartments of the inner liner, with the weight of the items supported by the bottom grid of the inner liner; close the lid 2, which presses down to fix the inner liner frame, while the sealing ring is compressed to seal the box body 1; when cleaning is required, reverse the operation, remove the inner liner, and then rinse the smooth inner bottom and inner liner grid of the box body 1 thoroughly.
[0041] Through the above steps, the partition plate 32 becomes a fixed structure using an integrally molded inner liner, eliminating the risk of it falling out and achieving stable partitioning. The smooth bottom of the box and the hollowed-out inner liner with cleaning gaps prevent dirt from hiding, improving the ease of cleaning of the device. At the same time, the inner liner module does not interfere with the sealing interface, ensuring the high sealing reliability of the original box body 1. Furthermore, the modular design supports inner liner replacement and overall placement and removal, improving the efficiency of organization and cleaning. This achieves stable partitioning, seamless and easy-to-clean box body 1, and reliable sealing.
[0042] Example 2
[0043] Optionally, this embodiment provides a highly sealed transparent plastic storage box with a partition layer.
[0044] The storage box includes a box body 1, a box lid 2, and an independent inner liner 3. The box body 1 and the box lid 2 can adopt existing high-sealing transparent plastic box structures. For example, the box body 1 has a sealing groove on the rim, and the inner edge of the box lid 2 has a matching sealing strip. A tight seal is achieved through a snap or locking mechanism.
[0045] The core of this embodiment lies in the independent partitioned inner liner 3; the partitioned inner liner 3 includes a top frame 31, multiple partition plates 32 extending vertically downward from the inside of the top frame 31, and a bottom support structure 33 connected to the bottom of all partition plates 32; the top frame 31 is a rectangular ring structure, the outer contour size of which is precisely matched with the inner wall size of the box 1, and the tolerance fit design is such that it can be easily placed in without obvious shaking; the partition plates 32 divide the inner liner space into multiple independent compartments; in this embodiment, the bottom support structure 33 is a grid-like plane formed by multiple horizontal and vertical connecting ribs, and its grid aperture is smaller than that of common small parts (such as M screws).
[0046] The installation and use principle of the inner liner is as follows: The user first places the inner liner 3 as a whole directly into the box body 1; after placement, the lower surface of the top edge 31 of the inner liner is supported on the inner step of the opening edge of the box body 1 or directly rests on the opening edge plane, thereby determining the axial (vertical) position of the inner liner in the box body 1; at this time, a continuous cleaning gap H is naturally formed between the bottom support structure 33 and the smooth inner bottom surface of the box body 1; at the same time, the bottommost end of the partition plate 32 is flush with or connected to the upper surface of the bottom support structure 33, so the space between the bottom end of the partition plate 32 and the bottom surface of the box body 1 is formed by this cleaning gap H.
[0047] When the item is placed inside, the lid 2 closes; the inner surface of the lid 2 presses against the upper surface of the top edge 31 of the inner liner 3; this pressure is directly transmitted to the edge of the box body 1 through the top edge 31 without generating lateral stress on the internal dividers 32, ensuring that all dividers 32 remain vertical; at the same time, the sealing strip of the lid 2 is evenly pressed into the sealing groove of the box body 1, achieving a high seal, and the sealing interface is completely unaffected by the inner liner.
[0048] Example 3
[0049] Optionally, based on Example 2, this embodiment further defines the manufacturing process of the partitioned inner liner 3 and a more specific bottom structure.
[0050] In this embodiment, the inner liner 3 is manufactured by a one-piece injection molding process, using transparent or semi-transparent polypropylene (PP) or polycarbonate (PC) materials; its top frame 31, partition plate 32 and bottom support structure 33 are a seamless continuous whole; this one-piece molding technology makes the inner liner structure strong, and the position of each partition plate 32 is permanently fixed, completely eliminating the loosening and tipping problems that may occur with traditional movable partitions.
[0051] The specific form of the bottom support structure 33 is a regular mesh grid; the mesh grid is formed by the interweaving of evenly distributed transverse and longitudinal ribs, forming square or rhomboid mesh holes; assuming the side length of the mesh hole is a and the minimum size of the item is d, in order to achieve the leak-proof effect, the design must satisfy a < d; for example, for the inner tube used to store electronic components, the side length a of the mesh hole can be designed to be 2mm to ensure that the 0805 packaged chip resistor will not fall off.
[0052] In this embodiment, the cleaning gap H is designed to be 3mm. This size is achieved by controlling the difference between the overall height of the inner liner 3 and the internal depth of the box 1. The principle is that when the inner liner is placed into the box 1, the cleaning gap H = the internal depth of the box 1 H_box - the total height of the inner liner 3 H_insert. This gap value (3mm) ensures that dust and small debris can fall to the bottom of the box, and the edges of the rag or water can smoothly enter and clean the area. At the same time, the gap is not so large that items can easily slide out of the compartment when the box is tilted.
[0053] Example 4
[0054] Optionally, this embodiment incorporates the features of the aforementioned embodiments and demonstrates the specific mating relationship between the box body 1 and the box lid 2.
[0055] The inner bottom surface of the box body 1 in this embodiment is an absolutely smooth plane without any protrusions, pits, or slots for fixing; the inner liner 3 adopts the one-piece molded mesh grid structure described in embodiment 3; after it is placed into the box body 1, the lid 2 is closed; the inner top surface of the lid 2 forms a surface contact with the upper surface of the top edge 31 of the inner liner 3; after the latch is locked, the lid 2 generates a downward pressing force F on the top edge 31; this pressing force F is sufficient to overcome the inertia of the inner liner and the contents, preventing the inner liner from jumping up and down or moving horizontally inside the box during transportation, further improving the stability of use.
[0056] The modularity of this embodiment is reflected in the fact that the inner compartment 3 is independently removable; when the user needs to change the sorting method or thoroughly clean it, he / she only needs to open the lid 2 and can lift the entire inner compartment 3 (along with the sorted items inside) out of the box body 1 by hand; after lifting it out, the box body 1, due to its smooth inner bottom surface, can be directly wiped with a damp cloth or rinsed with water, with extremely high cleaning efficiency; the removed inner compartment 3 can also be rinsed separately under the tap, and the water can quickly flow away and dry through the mesh grid and cleaning gap design.
[0057] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
