[0018] In the figure: 1. Base body; 2. Receiving cavity; 3. Separating rib; 4. First placement area; 5. Second placement area; 6. Fitting cavity; 7. Limiting cavity; 8. Material removal clearance groove; 9. U-shaped groove. Detailed Implementation

[0019] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0020] Example 1 like Figure 1As shown in the embodiment of this utility model, a blister tray is described, including a tray body 1. The upper surface of the tray body 1 is provided with a receiving cavity 2. A dividing rib 3 is provided in the middle of the receiving cavity 2, dividing the receiving cavity 2 into a first placement area 4 and a second placement area 5. The first placement area 4 is provided with a cross-shaped fitting cavity 6, and the fitting cavity 6 is provided with a receiving groove that matches the shape of the injection bottle. The second placement area 5 is provided with a limiting cavity 7, and the limiting cavity 7 is provided with a positioning groove for fixing the liquid transfer device.

[0021] In this embodiment, by dividing the receiving cavity 2 on the base body 1 into a first placement area 4 and a second placement area 5, compatible placement of injection vials and drug transfer devices of different specifications is achieved. The cross-shaped interlocking cavity 6 and the receiving groove of the first placement area 4 can accommodate a variety of injection vials, while the limiting cavity 7 and the positioning groove of the second placement area 5 are used to fix the drug transfer device. This avoids the need to design molds separately for different specifications of products, reduces mold development investment, and reduces storage space occupation and management pressure.

[0022] like Figure 1 As shown, the fitting cavity 6 is composed of a first step surface and a second step surface that are perpendicular to each other. Both ends of the first step surface and the second step surface are provided with U-shaped grooves 9 that correspond to the shape of the injection bottle.

[0023] In this embodiment, the fitting cavity 6 is designed to consist of a first step surface and a second step surface that are perpendicular to each other, with the second step surface located above the first step surface; this allows the base body 1 to provide multiple load-bearing areas of different sizes or heights without increasing the overall size.

[0024] Specifically, the second step surface is set above the first step surface, so that injection bottles with larger diameters can be stably placed in the U-shaped groove 9 of the lower first step surface, while injection bottles with smaller diameters can be placed in the U-shaped groove 9 of the higher second step surface. This improves the versatility of the base for injection bottles of different sizes, so that the same blister base can accommodate injection bottles of different diameters or heights.

[0025] Meanwhile, the mutually perpendicular stepped surfaces match the original cross-shaped layout inside the first placement area 4, effectively utilizing the internal space and enabling the fixing of injection bottles of different specifications within the first placement area 4. In addition, U-shaped grooves 9 corresponding to the shape of the injection bottles are provided at both ends of the first and second stepped surfaces, enhancing the fixing effect of the injection bottles. By closely fitting the contour of the U-shaped grooves 9 with the shape of the injection bottle, the two ends of the injection bottle can be limited and locked, preventing the injection bottle from shaking, shifting, or even falling during transportation or storage, thereby ensuring the stability of the injection bottle after placement.

[0026] In this embodiment, the diameter of the U-shaped groove 9 on the first stepped surface is larger than the diameter of the U-shaped groove 9 on the second stepped surface. When a larger-diameter injection bottle needs to be placed, the injection bottle can be engaged and fixed within the U-shaped groove 9 with the larger diameter on the first stepped surface; when a smaller-diameter injection bottle needs to be placed, the injection bottle can be engaged and fixed within the U-shaped groove 9 with the smaller diameter on the second stepped surface. This allows the blister tray to accommodate at least two different outer diameter injection bottles, improving the versatility of the tray.

[0027] On one side of the first and second step surfaces, there are arc-shaped positioning protrusions on the U-shaped groove 9. The arc-shaped protrusions can fit the shape of the injection bottle, which will not scratch the bottle and can also ensure the fit of the limit, effectively preventing the injection bottle from shaking, shifting or even tipping out during handling and transportation.

[0028] The limiting cavity 7 has an elongated oval cross section, which corresponds to the outer contour of the liquid transfer device and restricts the liquid transfer device from circumferential shaking or displacement within the limiting cavity 7. The limiting cavity 7 has a recessed cylindrical cavity in the middle, which can fit the protruding cylindrical structure of the liquid transfer device itself. By combining the design of the elongated oval cross section and the recessed cylindrical cavity, the positioning and fixation of the liquid transfer device are achieved, reducing the risk of displacement or impact during storage and transportation.

[0029] like Figure 2 As shown, material-receiving clearance grooves 8 are provided on both the left and right sides of the limiting cavity 7. The material-receiving clearance grooves 8 are arc-shaped structures that bulge outwards. By setting the material-receiving clearance grooves 8 on the left and right sides of the limiting cavity 7, space can be provided for the fingers to accommodate force, making it convenient for operators to apply force with their fingers when picking up products.

[0030] The reinforcing ribs are evenly distributed on the side wall of the base body 1, and the reinforcing ribs extend vertically along the side wall of the base body 1.

[0031] The reinforcing ribs enable the entire sidewall to withstand a more uniform load, thereby making the base tray body 1 more resistant to external forces such as stacking pressure or lateral compression, thus ensuring the stability of the thermoformed base tray during transportation and storage, and providing stable and reliable protection for the products placed inside the base tray body 1.

[0032] The height of the partition rib 3 is not lower than the height of the side walls of the first placement area 4 and the second placement area 5, so as to prevent products in different placement areas from colliding with each other. When the blister tray is shaken, tilted or subjected to external impact, the products placed in the first placement area 4 and the second placement area 5 can be effectively blocked by their respective side walls and the partition rib 3.

[0033] The working principle of this utility model: The partition rib 3 divides the receiving cavity 2 into a first placement area 4 and a second placement area 5. The first placement area 4 uses a cross-shaped fitting cavity 6 and U-shaped grooves 9 of different heights and diameters to accommodate injection bottles of various outer diameters and heights. The arc-shaped positioning bosses prevent the bottle from shaking and shifting. The elongated oval limiting cavity 7 of the second placement area 5 matches the shape of the liquid transfer device, and the concave cylindrical cavity below adapts to the protruding structure of the liquid transfer device, effectively limiting circumferential shaking.

[0034] Example 2 Another aspect of this utility model provides a blister box, including a lid and a blister tray as described above. The lid and the blister tray are fastened together, forming a closed space inside the packaging after the lid and tray body 1 are fastened together. This effectively blocks external dust, moisture, and other contaminants, thus meeting the product's dust and moisture protection requirements. Simultaneously, the tight fastening between the lid and the tray provides an additional physical barrier for the internal items, enhancing the overall structural strength and impact resistance of the packaging, and effectively preventing damage to the product due to collisions during transportation and storage.

[0035] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
