Description

Technical Field

[0001] The utility model relates to a packaging structure, in particular to an inner packaging. Background Art

[0002] During the transportation and logistics process, goods are often packaged to provide shock absorption and protection. Inner packaging is the protective layer surrounding the product. Its primary functions include protecting the product from damage, shielding it from direct contact with the external environment, and displaying some product information. Outer packaging, an additional layer of packaging, is used to protect the inner packaging and the product during transportation and storage. Outer packaging is typically sturdy and can withstand certain pressures, impacts, and weather changes. It also serves as a crucial medium for displaying comprehensive product information, such as brand logos, production dates, and instructions for use.

[0003] Prior art inner packaging generally utilizes a fixed structure. However, this type of fixed-structure inner packaging not only requires a significant amount of space during transportation and storage, but also has fixed dimensions and fixed positions. Different sized packages require different sized inner packaging, which creates cost pressure for companies and limits product versatility. Furthermore, multiple inner packaging structures are similar, making confusion easy during production and warehousing, increasing the complexity of production and warehousing management. Finally, due to the specific structure of the packaging, it is environmentally unfriendly, has a limited functionality, and is difficult to recycle and reuse. Utility Model Content

[0040] Example 1

[0041] The present invention provides an inner packaging capable of being used for a developer cartridge, a drum assembly, or a process cartridge A formed by combining the developer cartridge and drum assembly. The developer cartridge, drum assembly, or process cartridge A refers to a product that is used in, and detachable from, an electrophotographic imaging device (or imaging device, image forming apparatus), such as a printer or copier, and includes a corresponding photosensitive member (drum assembly) and / or developer member (developer cartridge). In other embodiments, the inner packaging can also be used for other products.

[0042] like Figure 1 and Figure 2 As shown, the inner packaging of the present invention includes a supporting portion 1 and a stretchable portion 2. When the inner packaging is in use, the stretchable portion 2 is stretched and protrudes outward from the supporting portion 1, thereby forming a accommodating space in the stretchable portion 2. The accommodating space is used to accommodate at least a part of the packaged object. The stretchable portion 2 is wrapped around at least a part of the packaged object, thereby providing a shock-absorbing and buffering protection for the packaged object, and can also support and fix the packaged object in the outer packaging to a certain extent, preventing the packaged object from colliding and displacing in the outer packaging.

[0043] like Figure 1 As shown, the inner packaging of this embodiment has an adjustable degree of stretching of the stretchable portion 2, so it can be used to package objects of different sizes, thereby improving the versatility of the inner packaging, reducing confusion that may easily occur during production and warehousing, and reducing the difficulty of production and warehousing management. Moreover, due to its good versatility, the inner packaging is easy to recycle and reuse.

[0044] like Figure 3 As shown, when the inner packaging is in an unused state, the stretchable portion 2 does not protrude outward from the supporting portion 1, and the stretchable portion 2 does not have the aforementioned accommodation space. This arrangement enables the inner packaging to have a smaller storage volume when in an unused state than when in use, thereby reducing the storage space for the inner packaging.

[0045] like Figure 3 As shown, in this embodiment, further, when the inner packaging is not in use, the support portion 1 and the stretchable portion 2 have a planar structure. The stretchable portion 2 is formed by applying a cutting line on the planar structure. The provision of the planar structure further reduces the space occupied by the inner packaging when not in use. In other embodiments, the support portion 1 and the stretchable portion 2 may also adopt a curved surface or other shaped structure. The cutting line enables the stretchable portion 2 to protrude outward from the support portion 1 when stretched, forming a hollow portion 5, while the stretchable portion 2 remains connected to the support portion 1.

[0046] like Figure 1 and Figure 3As shown, in this embodiment, the cutting lines specifically include a first cutting line 21, a second cutting line 22, and a third cutting line 23. There are two first cutting lines 21, one on each side of the second cutting line 22 and the other on the third cutting line 23, alternating between the second cutting lines 22 and the third cutting lines 23. The second cutting lines 22 are non-parallel to and non-overlapping with the first cutting lines 21 (i.e., there is an angle between the two, either inclined or perpendicular to each other). First separations 24 are defined at each end of the second cutting line 22 relative to the first cutting line 21. This means that the ends of the second cutting line 22 do not extend to the first cutting line 21, and no cutting is performed at the locations of the first separations 24. The third cutting line 23 is non-parallel to and non-coincident with the first cutting line 21 (i.e., there is an angle between the two, and they are inclined or perpendicular to each other). It includes a first sub-cutting line 231 and a second sub-cutting line 232 extending on the same straight line. The first sub-cutting line 231 and the second sub-cutting line 232 respectively intersect with the first cutting line 21. A second spacer 25 is provided between the first sub-cutting line 231 and the second sub-cutting line 232. That is, the first sub-cutting line 231 does not extend to the second sub-cutting line 232, and the position of the second spacer 25 is not cut. In this way, by setting the cutting line, the stretchable portion 2 can form a hollow portion 5 when stretched, and the stretchable portion 2 can remain connected to the support portion 1 during stretching and will not detach from the support portion 1.

[0047] like Figure 1 and Figure 3 As shown, in this embodiment, the interior of the support portion 1 is further hollow, and the stretchable portion 2 is disposed in the hollow portion of the support portion 1. Specifically, the support portion 1 is a hollow square or rectangular structure, and the stretchable portion 2 is a square or rectangular structure embedded in the support portion 1 when not stretched. The hollow portion 5 is a diamond structure. The second cutting line 22 is parallel to the third cutting line 23, and the second cutting line 22 and the third cutting line 23 are perpendicular to the first cutting line 21. The first cutting line 21, the second cutting line 22, and the third cutting line 23 are all parallel to the corresponding side edges of the support portion 1.

[0048] In this embodiment, there may be two inner packages, which are used in pairs to wrap the two ends of the packaged object respectively and then placed in the outer package.

[0049] The inner packaging of this embodiment can be made of a material that has elastic cushioning properties, such as pearl cotton or corrugated paper.

[0050] The inner packaging of the present invention adopts a stretchable structure, so that the inner packaging has a smaller storage volume when it is not in use than when it is in use, which is convenient for the storage of the inner packaging. The stretching degree of the stretchable part 2 is adjustable, so it can be used to package objects of different sizes, thereby improving the versatility of the inner packaging, reducing the confusion that is easy to occur during production and warehousing, and reducing the difficulty of production and warehousing management. Moreover, due to its good versatility, the inner packaging is easy to recycle and reuse.

[0051] Example 2

[0052] like Figure 4 As shown, this embodiment is generally the same as the embodiment, and only the differences from the embodiment 1 are described below: the inner packaging of this embodiment includes a first packaging part 3 and a second packaging part 4. It can be understood that the first packaging part 3 and the second packaging part 4 are the same as the single inner packaging of the embodiment 1, but the second packaging part 4 is rotated at a certain angle (for example, 90 degrees) relative to the first packaging part 3, and the first packaging part 3 and the second packaging part 4 are connected to each other and can be folded with each other, and the stretchable parts 2 of the two overlap, and after stretching, the packaged objects are more comprehensively wrapped in different directions.

[0053] like Figure 4 and Figure 5 As shown, specifically, in this embodiment, the inner packaging includes a first packaging portion 3 and a second packaging portion 4, the first packaging portion 3 has a first supporting portion 31 and a first stretchable portion 32, and the second packaging portion 4 has a second supporting portion 41 and a second stretchable portion 42; when the inner packaging is in an unused state, the first stretchable portion 32 and the second stretchable portion 42 at least partially overlap, and when the inner packaging is in use, the first stretchable portion 32 and the second stretchable portion 42 can be pulled outward at the same time and simultaneously wrap at least a portion of the packaged object. In this embodiment, the first packaging portion 3 and the second packaging portion 4 overlap correspondingly, wherein the first supporting portion 31 and the second supporting portion 41 overlap correspondingly, and the first stretchable portion 32 and the second stretchable portion 42 overlap correspondingly,

[0054] like Figures 4 to 6As shown, further, the first support portion 31 and the second support portion 41 are connected to each other and can be folded along the connection so that the first stretchable portion 32 and the second stretchable portion 42 at least partially overlap; after the first stretchable portion 32 is stretched, it can wrap the packaged object on opposite sides of the first direction, and after the second stretchable portion 42 is stretched, it can wrap the packaged object on opposite sides of the second direction (shown as left and right in the figure). The first direction and the second direction are not parallel and do not overlap, that is, an angle is formed between the first direction and the second direction, which can be inclined or vertical, specifically vertical in this embodiment, then the packaged object can be wrapped on opposite sides of the first direction and opposite sides of the second direction, that is, the top, bottom, left and right four directions in the figure.

[0055] In other embodiments, the first packaging portion 3 and the second packaging portion 4 may be unconnected and directly comprise two single structures, with the first packaging portion 3 and the second packaging portion 4 stacked together for use. Specifically, four inner packages are provided in the first embodiment, with two inner packages forming a group, i.e., two groups of inner packages, each for one end of the packaged article. Each group of inner packages overlaps at an angle (e.g., 90 degrees) to each other, and then the stretchable portions 2 of the two inner packages are stretched to wrap around one end of the packaged article. In this embodiment, the first packaging portion 3 and the second packaging portion 4 are interconnected and folded during use so that the first packaging portion 3 and the second packaging portion 4 overlap. Because the first packaging portion 3 and the second packaging portion 4 are interconnected, they can be prevented from separating and falling off during use. Furthermore, the connected inner packages are a single piece, making them more convenient to access.

[0056] like Figure 7 As shown, specifically, in this embodiment, the settings of the cutting lines of the first packaging part 3 and the second packaging part 4 are the same as those in Example 1, except that all the cutting lines of the first packaging part 3 are rotated 90 degrees relative to all the cutting lines of the second packaging part 4, so that the first stretchable part 32 and the second stretchable part 42 have different wrapping positions for the packaged object after stretching, forming a complementary relationship. For example, in this embodiment, the packaged object can be wrapped in four directions: up, down, left and right, so that the packaged object can be wrapped more comprehensively, further increasing the protective effect of shock absorption and buffering.

[0057] The above are only some embodiments of the present invention. Those skilled in the art will appreciate that, without departing from the inventive concept of the present invention, they may make various modifications and improvements, or freely combine the above technical solutions, including freely combining the technical features of the above different embodiments, all of which fall within the scope of protection of the present invention.
