[0001] This utility model belongs to the field of packaging technology for positive and negative electrode products of battery cells, and relates to a packaging container for positive and negative electrode disc products of battery cells. Background Technology

[0002] Currently, the primary packaging method for battery cell positive and negative electrode wafers is blister packaging. While this technology provides some degree of fixation and protection for the product, it also has several drawbacks.

[0003] First, the cost of blister packaging is too high, which not only increases production costs for companies but also leads to unnecessary waste of resources. In today's increasingly competitive market, excessively high costs have become a significant factor restricting product competitiveness.

[0004] Secondly, the structure and size design of blister packs may not be optimized, resulting in limited space utilization. This means that the number of products that can be packed within a certain volume is insufficient to meet actual needs, thus affecting packaging efficiency and logistics costs.

[0005] In summary, the blister packaging method for positive and negative electrode wafer products has significant shortcomings in terms of cost, packaging efficiency, and space utilization. Utility Model Content

[0006] The purpose of this utility model is to provide a packaging container for positive and negative electrode wafer products of battery cells, and to solve at least one of the technical problems mentioned in the background art.

[0007] The objective of this utility model is achieved through the following technical solution:

[0008] A packaging container for positive and negative electrode wafers of battery cells includes a tube body. A plurality of circumferentially distributed convex ribs are axially distributed within the tube body. The top surface of each convex rib is arc-shaped, and the arc-shaped surfaces lie on the same circle centered on the central axis of the tube body. A bottom cover is detachably mounted on the lower end of the tube body, and a top cover is detachably mounted on the upper end of the tube body. A cushioning foam is snap-fitted into the top cover, with one end of the cushioning foam exposed outside the top cover to form a press-fit end face.

Example

[0036] See Figures 1-7 As shown, a packaging container for a battery cell positive and negative electrode wafer product includes a tube body 1, within which several circumferentially distributed protruding ribs 11 are axially distributed. The top surfaces of these protruding ribs 11 are designed in an arc shape, with the arc shape located on the same circle M centered on the central axis of the tube body 1. This design creates a perfect cavity inside the tube body, the shape of which perfectly matches the contour of the product 5 (a battery cell positive and negative electrode wafer product). When the product 5 is placed inside the tube body 1, its edges can fit tightly against the top surfaces of the protruding ribs 11, thus achieving stable support and positioning.

[0037] The lower end of the tube body 1 is detachably connected to a bottom cover 2, and the upper end of the tube body 1 is detachably connected to a top cover 3, facilitating the loading and unloading of the product 5. A cushioning foam 4 is snap-fitted into the top cover 3, with one end of the cushioning foam 4 exposed outside the top cover 3 to form a press-fit end face. This provides additional cushioning protection when closed, ensuring the stability of the product 5 within the tube body and effectively preventing damage caused by shaking.

[0038] In this embodiment, there are three convex rib structures 11, which are evenly distributed on the tube body 1 in a circumferential array. This layout not only enhances the structural strength of the entire packaging container, but also ensures the uniform distribution and stable support of the product within the tube body 1.

[0039] When using this product, carefully select the appropriate bottom cover 2 and tube body 1 for assembly based on the product's size and the specific requirements of the packaging design. In terms of the operation process, first, securely install the bottom cover 2 to the bottom of the tube body 1. Then, arrange the products 5 one by one into the tube body 1 in a predetermined order, ensuring that each product fits tightly against the inner wall of the tube. This achieves stable placement of the products inside the tube, avoiding mutual compression and collision. As products are continuously loaded, use cushioning foam 4 made of polyethylene or polyurethane with good elasticity and shock absorption properties, placing it properly on top of the stacked products 5 to fill the remaining space. This effectively cushions and stabilizes the products, preventing damage caused by shaking during subsequent transportation or handling. Finally, cover with the top cover 3 to ensure the entire tube structure is stable and intact, successfully achieving the expected tube loading goal.

[0040] In this embodiment, the bottom cover 2 and the tube body 1 are connected by a reliable method, which can be a snap-fit ​​connection that is easy to install and remove quickly, or a threaded connection that ensures a tight fixation. Similarly, the top cover 3 and the tube body 1 are also connected by a snap-fit ​​connection, which not only ensures the stability of the structure, but also makes it easy for users to open or close the container without damaging the packaging.

[0041] Specifically, when the bottom cover 2 is matched with the tube body 1 in the form of a snap-fit, the bottom cover 2 has a first protrusion 21, which can be smoothly inserted into the interior of the tube body 1 to form a preliminary assembly positioning. A first clearance groove 22 is provided on the first protrusion 21. This design is to allow the convex structure 11 on the tube body 1 to be smoothly embedded, thereby increasing the stability and sealing of the connection.

[0042] The snap-fit ​​connection between the bottom cover 2 and the tube body 1 provides two implementation methods. The first method is as follows: Figure 6 As shown, the first protrusion 21 has a pair of upwardly extending protrusions 23 on both sides. These protrusions can precisely correspond to and engage with the pre-set slots inside the tube body 1, achieving a stable locking effect. Alternatively, a second slot is provided on the circumferential edge of the first protrusion 21. Correspondingly, a locking protrusion with a shape and size perfectly matched to the second slot is specially designed at the end of the tube body 1. When the bottom cover 2 is pushed into the tube body 1, the locking protrusion can smoothly slide into the second slot, thus achieving another form of locking fixation. Both locking methods effectively prevent accidental detachment between the bottom cover 2 and the tube body 1, ensuring the stability and durability of the overall structure.

[0043] Of course, to meet the needs of different application scenarios, the connection between the bottom cover 2 and the tube body 1 can also be a threaded connection. In this case, the lower end of the tube body 1 is specially designed with an internal thread structure, which can tightly cooperate with the external thread structure on the bottom cover 2 to achieve a rotational fastening connection. It is worth noting that in this connection method, the convex rib structure 11 is designed above the internal thread structure. This not only ensures the firmness of the connection, but also effectively prevents the bottom cover 2 from interfering with other internal structures of the tube body 1 during rotation, ensuring the smooth operation and stability of the overall structure.

[0044] In this embodiment, the top cover 3 has a second protrusion 31, which can be smoothly inserted into the tube body 1, corresponding to the first protrusion 21 of the bottom cover 2. A second clearance groove 32 is also specially provided on the second protrusion 31 to ensure that the convex structure 11 can be smoothly embedded and enhance the stability of the connection.

[0045] It is worth noting that the surface of the second protrusion 31 is designed with a sealing fitting part 33. This structure can make close contact with the inner wall of the tube body 1 to form an effective seal. The sealing fitting part 33 adopts a multi-segment arc-shaped sealing lip design. This design not only increases the sealing area but also improves the reliability and durability of the seal. At the same time, the thickness of the sealing lip is designed to be narrower at the bottom and wider at the top, so that its outer surface presents a downward-sloping curved surface or bevel. This design can improve the firmness of the top cover 3 after it is installed on the tube body 1.

[0046] This invention achieves a tight arrangement of positive and negative electrode wafers for battery cells through the ingenious design of the tube body 1 and the clever application of the bottom cover 2 and top cover 3. Each product can fit snugly against the inner wall of the tube body 1, ensuring stability and preventing mutual squeezing and collisions. Furthermore, this design significantly improves the utilization of packaging space, allowing more products to be properly packaged within a limited volume. The addition of cushioning foam 4 further enhances the product's protective effect, effectively preventing damage caused by shaking during subsequent transportation or handling, providing strong assurance for the safe transport of positive and negative electrode wafers for battery cells.
