Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, specifically a blister packaging box. Background Technology

[0002] Blister packaging is a type of box-shaped packaging made using a vacuum forming process. The process involves heating the material to a softened state, then using vacuum adsorption technology to press it against a mold surface. After cooling, it solidifies, ultimately forming a packaging box with a specific shape and function.

[0003] A search revealed a Chinese utility model patent application with authorization announcement number CN222860070U, published on May 13, 2025, which describes a blister packaging box. The application states that it "includes a box body as a connecting frame, with protruding edges integrally formed on both the left and right sides of the box body. A lid component is connected to the box body to seal the box body, including a lid that slides with the box body. The outer side of the lid is symmetrically and integrally formed with buckles that engage with the protruding edges. Multiple sets of slots are linearly and equidistantly arranged inside the box body. A partition is provided between each pair of opposing slots. A seat is integrally formed on the outer side of the partition that engages with the slot. The protruding edges and buckles restrict the lid, allowing it to slide along the top of the box body for easy control of the opening size. Furthermore, the slots and seats engage to place the partition inside the box, facilitating adjustment of the internal space to accommodate objects of different sizes."

[0004] Further searching revealed a Chinese utility model patent application with authorization number CN219193110U, published on June 16, 2023, which describes a blister packaging box. The application states that it "includes a box body, with a positioning ring connected to the top of the box body, a positioning block connected to the outer side of the top of the positioning ring, a connecting ring connecting the positioning blocks, and a box lid connected to the top of the connecting ring. When it is necessary to open the blister packaging box to remove fruit, the side of the box lid can be pressed directly. Because the box lid is made of blister material, it will deform, causing the connecting ring to detach from the bottom of the positioning block, thus opening the box lid for easy fruit removal. Since the box lid separates from the box body after opening, the box body is less likely to tip over even if only one side of the fruit is removed, making the packaging box more convenient to use."

[0005] However, the above method cannot adjust the depth of the packaging box according to the volume of the object being packaged. This results in a large gap between the object and the box, making it prone to violent collisions during transportation and ultimately causing damage to the item.

[0006] Therefore, a blister packaging box is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a blister packaging box to solve the problems mentioned in the background art. To achieve the above purpose, this utility model provides the following technical solution: A blister packaging box includes a top box and a bottom box. The bottom of the top box is integrally formed with a first fixing plate, and the top of the bottom box is integrally formed with a second fixing plate. A limiting component is installed on each side of the first fixing plate. The limiting component and the second fixing plate cooperate with each other. Multiple partitions are slidably installed at equal distances inside the top box and the bottom box. Multiple sliding plates are slidably installed at equal distances inside the top box and the bottom box. A positioning component is installed inside each side of the sliding plate.

[0008] Preferably, a limiting groove is provided inside each of the two sides of the second fixing plate, and multiple first sliding grooves are provided at equal intervals on the inner walls of the top box and the bottom box.

[0009] Preferably, two sliders are welded to each side of the slide plate, and the sliders are slidably installed inside the first groove.

[0010] Preferably, the inner walls on both sides of the top box and the bottom box are provided with a plurality of second sliding grooves at equal intervals, and a strip is welded to each side of the partition, the strip being slidably installed inside the second sliding groove.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: See Figure 1 — Figure 5A blister packaging box includes a top box 1 and a bottom box 4. The bottom of the top box 1 is integrally formed with a first fixing plate 2, and the top of the bottom box 4 is integrally formed with a second fixing plate 3. A limiting component 5 is installed on each side of the first fixing plate 2, and the limiting component 5 and the second fixing plate 3 cooperate with each other. Multiple partitions 11 are slidably installed at equal distances inside the top box 1 and the bottom box 4. Multiple sliding plates 12 are slidably installed at equal distances inside the top box 1 and the bottom box 4. A positioning component 8 is installed inside each side of the sliding plate 12.

[0025] A limiting groove 6 is provided on the inside of each side of the second fixing plate 3, and multiple first sliding grooves 7 are provided at equal intervals on the inner walls of the top box 1 and the bottom box 4.

[0026] Two sliders 13 are welded to each side of the slide plate 12, and the sliders 13 are slidably installed inside the first slide groove 7.

[0027] Multiple second sliding grooves 14 are provided at equal intervals on the inner walls of the top box 1 and the bottom box 4, and an insert 15 is welded to each side of the partition 11. The insert 15 is slidably installed inside the second sliding groove 14.

[0028] A second rubber pad 10 is attached to the inner walls on both sides of the top box 1 and the bottom box 4, and a first rubber pad 9 is attached to both sides of the partition 11.

[0029] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, when using a lidded packaging box to package items, the operator can adjust the sliding plate 12 installed inside the top box 1 and bottom box 4 according to the size of the items to be packaged. By controlling the positioning components 8 installed on both sides of the sliding plate 12, the operator can control the sliding plate 12 to slide inside the top box 1 and bottom box 4. The positioning holes 16 on the inner walls of both sides of the top box 1 and bottom box 4 can fix the position of the sliding plate 12. By adjusting the installation position of the sliding plate 12 inside the top box 1 and bottom box 4 respectively, when packaging items, the sliding plate 12 installed inside the top box 1 and bottom box 4 can be made to contact the top and bottom of the items respectively, thus... The items are held between the top box 1 and the bottom box 4. At the same time, multiple partitions 11 are slidably installed inside the top box 1 and the bottom box 4. The partitions 11 can separate two adjacent items and allow packaging personnel to flexibly adjust the packaging space inside the top box 1 and the bottom box 4. Since a second rubber pad 10 is attached to the inner wall on both sides of the top box 1 and the bottom box 4, and a first rubber pad 9 is attached to both sides of the partition 11, the first rubber pad 9 and the second rubber pad 10 can provide soft protection for the outside of the items, preventing the items from being damaged by collision with the packaging box during transportation.

[0030] Example 2: The limiting component 5 includes a first mounting groove 501 opened inside the first fixed plate 2, and a plurality of first spring slide rods 502 are fixed at equal intervals inside the first mounting groove 501. A limiting insert plate 503 is slidably sleeved on the outer side of the first spring slide rod 502, and the bottom of the limiting insert plate 503 is hook-shaped. The positioning component 8 includes a second mounting groove 801 opened inside the slide plate 12, and a second spring slide rod 803 is welded inside the second mounting groove 801. A plurality of positioning holes 16 are opened at equal intervals on both sides of the inner walls of the top box 1 and the bottom box 4. A control plate 804 is slidably sleeved on the outer side of the second spring slide rod 803, and the top of the control plate 804 slides out of the interior of the second mounting groove 801. A reset spring 805 is sleeved on the outer side of the second spring slide rod 803, and two limiting insert rods 802 are welded on one side of the control plate 804. The limiting insert rods 802 are fitted with the positioning holes 16.

[0031] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, when the top box 1 and bottom box 4 are combined to protect the items, the packaging personnel squeeze one side of the limiting inserts 503 installed inside the first mounting groove 501 on both sides of the first fixing plate 2, so that the two limiting inserts 503 slide relative to each other, thereby causing the limiting inserts 503 to slide along the installation direction of the first spring slide rod 502, while compressing the spring installed on the outside of the first spring slide rod 502, so that the bottom of the limiting insert 503 is above the limiting groove 6. Then, the bottom of the limiting insert 503 is inserted into the interior of the limiting groove 6, so that the barbed part of the bottom of the limiting insert 503 extends out of the interior of the limiting groove 6. Then, the two are released. When the limiting insert plate 503 is pressed, the compressed spring on the outside of the first spring slide rod 502 rebounds, pushing the limiting insert plate 503 out. This causes the hook-shaped part at the bottom of the limiting insert plate 503 to get stuck at the bottom of the second fixing plate 3, thereby merging the top box 1 and the bottom box 4. When disassembling, the two limiting insert plates 503 are pressed again, thereby separating the hook-shaped part at the bottom of the limiting insert plate 503 from the bottom of the second fixing plate 3. Then, the limiting insert plate 503 can be pulled out from the limiting groove 6 to separate the top box 1 and the bottom box 4. This is very convenient and avoids the situation where the main body of the top box 1 and the bottom box 4 is deformed due to the compression of the top box 1 and the bottom box 4.

[0032] When the sliding plate 12 slides inside the top box 1 or bottom box 4, the packaging personnel control the top of the two control plates 804 with two fingers, causing the control plates 804 to slide along the installation direction of the second spring slide rod 803 while compressing the return spring 805 sleeved on the outside of the second spring slide rod 803. This causes the limiting rod 802 to be housed inside the second mounting groove 801 and separated from the positioning hole 16. At this time, the sliding plate 12 can slide inside the top box 1 or bottom box 4. After moving the sliding plate 12 to the designated position, the control of the control plate 804 is released. At this time, the return spring 805 rebounds, thereby popping the limiting rod 802 out of the second mounting groove 801 and inserting it into the positioning hole 16 to fix the position of the sliding plate 12.

[0033] Working principle: When using this blister packaging box, first adjust the position of the slide plate 12 according to the volume of the items to be packaged: control the control plate 804 on the slide plate 12 with two fingers, so that it slides along the second spring slide bar 803 and compresses the return spring 805, allowing the limit insert 802 to disengage from the positioning hole 16. After sliding the slide plate 12 to the appropriate position, release the control plate 804, and the return spring 805 rebounds to push the limit insert 802 into the positioning hole 16, completing the fixation of the slide plate 12. Next, adjust the partition 11 according to the quantity and size of the items: slide the insert 15 in the second slide groove 14 to move the partition 11 to the required position, using... The first rubber pad 9 and the second rubber pad 10 provide soft protection for the items. During packaging, the items are placed in the bottom box 4, the top box 1 is closed, and the limiting inserts 503 on both sides of the first fixing plate 2 are squeezed to make them slide relative to each other along the first spring slide bar 502 and compress the spring. The bottom of the limiting insert 503 is inserted into the limiting groove 6 of the second fixing plate 3. After being released, the spring of the first spring slide bar 502 rebounds, so that the hook-shaped part at the bottom of the limiting insert 503 is stuck at the bottom of the second fixing plate 3, thus completing the merging and fixing of the top box 1 and the bottom box 4. When it is necessary to remove the items, the limiting insert 503 is squeezed to make it disengage from the limiting groove 6, and the top box 1 and the bottom box 4 are separated.

[0034] Compared to the prior art and common blister packaging boxes, which cannot adjust their internal depth according to the volume of the object being packaged, resulting in large gaps between the object and the box and easy damage during transportation, the blister packaging box of this application achieves flexible adjustment of packaging space and optimized protection of items through the design of a sliding plate 12 and a partition 11. Before packaging, the operator can first adjust the position of the sliding plate 12 using the positioning component 8, so that the sliding plates 12 in the top box 1 and bottom box 4 contact the top and bottom of the item respectively to clamp the item. Then, the partition 11 is adjusted by sliding the insert 15 in the second slide groove 14 to separate adjacent items and adapt to different sizes. At the same time, the first rubber pad 9 and the second rubber pad 10 provide soft protection, and the limiting insert 503 of the limiting component 5 cooperates with the limiting groove 6 to achieve convenient opening and closing of the top box 1 and bottom box 4 without deformation. These designs significantly reduce the gap between the item and the box, reduce the risk of damage from collisions during transportation, and effectively solve the pain points of insufficient packaging flexibility and poor item protection in existing technologies.
