Heat-resistant blister tray

Abstract

The application discloses a heat-resistant blister tray and belongs to the technical field of blister trays. The blister tray comprises a tray body which is integrally formed by injection molding of polypropylene material. The tray body is integrally formed by injection molding of polypropylene material in the application. Polypropylene has certain heat resistance, so that the heat resistance of the tray body is relatively high. The reinforcing protrusions on the upper surface of the tray body enclose a plurality of air flow channels. These air flow channels provide channels for air flow, so that the locally accumulated heat can be quickly dissipated, reducing the long-term residence of heat in a certain area, thereby reducing the risk of softening of the material due to local overheating. In addition, the protruding structure of the reinforcing protrusions can also improve the overall rigidity of the tray body, enhancing the bending resistance and deformation resistance of the tray body in a high-temperature environment. A plurality of reinforcing protrusions are arranged in the rectangular groove of the bottom wall of the storage groove to strengthen the deformation resistance of the bottom of the storage groove, thereby reducing the deformation of the storage groove.

Description

Technical Field

[0001] This application relates to the field of blister tray technology, and more particularly to a heat-resistant blister tray. Background Technology

[0002] Blister trays, as lightweight, low-cost, and easily moldable packaging and turnover carriers, have been widely used in many fields such as food, medicine, electronics, and industrial parts. Through thermoforming, plastic sheets are processed into products with specific grooves, ribs, or partition structures, enabling them to position, protect, isolate, and facilitate the handling of products, thus occupying an important position in modern logistics and packaging systems.

[0003] Currently, heat-resistant thermoforming pallets on the market mainly rely on the improved heat resistance of the material itself. Traditional pallets mostly adopt a flat base with a simple groove structure. The contact area between the pallet and high-temperature products and heat sources lacks an effective heat conduction and dispersion structure. Local heat accumulation can easily lead to excessive softening of the material. After the material softens at high temperatures, the load-bearing area is prone to deformation due to concentrated stress, resulting in unstable product support. Therefore, an improvement has been made to a heat-resistant thermoforming pallet. Utility Model Content

[0004] In view of the shortcomings of the prior art, this application provides a heat-resistant thermoforming tray, which overcomes the shortcomings of the prior art and aims to solve the problems in the prior art.

[0005] To achieve the above objectives, this application provides the following technical solution: a heat-resistant blister tray, comprising a tray body, wherein the tray body is integrally injection molded from polypropylene material, the upper surface of the tray body is provided with a plurality of reinforcing protrusions, and the reinforcing protrusions surround the upper surface of the tray body to form a plurality of air circulation grooves, the upper surface of the tray body is provided with a plurality of storage slots for storing items, the bottom wall of the storage slots is provided with rectangular grooves, and the interior of the rectangular grooves is provided with a plurality of reinforcing ribs.

[0006] By adopting the above technical solution, the pallet body is injection molded from polypropylene material. Polypropylene has a certain heat resistance, which makes the pallet body highly heat resistant. The reinforcing protrusions on the upper surface of the pallet body form several air circulation grooves. These air circulation grooves provide channels for air flow, allowing locally accumulated heat to dissipate quickly and reducing the long-term residence of heat in a certain area. This reduces the risk of the material softening due to local overheating. In addition, the raised structure of the reinforcing protrusions can also improve the overall rigidity of the pallet body and enhance its resistance to bending and deformation in high-temperature environments. Several reinforcing ridges are set in the rectangular grooves on the bottom wall of the storage compartment to strengthen the deformation resistance of the bottom of the storage compartment, thereby reducing the deformation of the storage compartment.

[0007] As a preferred technical solution of this application, a plurality of the reinforcing ridges are equally spaced inside the rectangular groove, and the top of the reinforcing ridges is flush with the bottom wall of the storage groove.

[0008] By adopting the above technical solution, several reinforcing ridges are evenly spaced inside the rectangular groove, which can make the bottom of the storage groove more uniformly stressed and avoid local deformation caused by uneven stress. The top of the reinforcing ridges is flush with the bottom wall of the storage groove, which can not only ensure the flatness of the bottom of the storage groove and facilitate the placement of items, but also enhance the structural strength of the storage groove.

[0009] As a preferred technical solution of this application, the upper surface of the tray body is provided with a pick-up and put-down groove on the outer side of the storage groove, and the inner wall of the pick-up and put-down groove is provided with an arc-shaped block.

[0010] By adopting the above technical solution, the pick-and-place slot facilitates users in picking up and placing items, provides a point of leverage, and makes it easy to pick up the tray or remove items from the tray. The arc-shaped block is used to enhance the structural strength of the pick-and-place slot.

[0011] As a preferred technical solution of this application, a plug-in rod is fixedly connected to the bottom of the tray body, a cross block is provided at the lower end of the plug-in rod, a plug-in hole is provided on the upper surface of the tray body for the plug-in rod to be inserted, and a cross hole is provided on the bottom wall of the plug-in hole.

[0012] By adopting the above technical solution, multiple pallet bodies can be stacked together through the cooperation between the plug rod, plug hole, cross block and cross hole.

[0013] As a preferred technical solution of this application, the number of the plug holes, cross holes, plug rods and cross blocks are the same and correspond one-to-one. The outer diameter of the plug rod is adapted to the inner diameter of the plug hole, and the outer dimensions of the cross block are adapted to the inner wall space dimensions of the cross hole.

[0014] By adopting the above technical solution, precise positioning and stable connection between pallet bodies can be achieved, preventing pallet bodies from misaligning or tipping over when stacked.

[0015] As a preferred technical solution of this application, the pallet body has symmetrically formed transport grooves on both outer walls.

[0016] By adopting the above technical solution, a convenient gripping part is provided for the main body of the pallet, making it easier for workers to move the pallet, especially when moving heavy items or moving in batches, which can effectively reduce the difficulty of moving and improve the efficiency of moving.

[0017] In summary, the beneficial effects of this application are as follows: In this application, the pallet body is injection molded from polypropylene material. Polypropylene has a certain degree of heat resistance, which makes the pallet body highly heat resistant. The reinforcing protrusions on the upper surface of the pallet body form several air circulation grooves. These air circulation grooves provide channels for air flow, allowing locally accumulated heat to dissipate quickly and reducing the long-term residence of heat in a certain area. This reduces the risk of the material softening due to local overheating. In addition, the raised structure of the reinforcing protrusions can also improve the overall rigidity of the pallet body and enhance its resistance to bending and deformation in high-temperature environments. Several reinforcing ridges are set in the rectangular grooves on the bottom wall of the storage compartment to strengthen the deformation resistance of the bottom of the storage compartment, thereby reducing the deformation of the storage compartment.

[0020] To make the technical means, creative features, objectives and effects of this application easy to understand, the following describes this application in conjunction with specific implementation methods.

[0021] like Figure 1 - Figure 4As shown, this embodiment provides a heat-resistant thermoformed tray, including a tray body 1. The tray body 1 is integrally injection molded from polypropylene material. Several reinforcing protrusions 2 are provided on the upper surface of the tray body 1, and the reinforcing protrusions 2 enclose several air circulation grooves 3 on the upper surface of the tray body 1. Several storage slots 4 for storing items are opened on the upper surface of the tray body 1. Rectangular grooves are opened on the bottom wall of the storage slots 4, and several reinforcing ribs 5 are provided inside the rectangular grooves. In use, the tray body 1 is integrally injection molded from polypropylene material. Polypropylene has a certain degree of heat resistance, making the tray body 1 heat-resistant. Due to its high heat resistance, the reinforcing protrusions 2 on the upper surface of the tray body 1 form several air circulation grooves 3. These air circulation grooves 3 provide channels for air flow, allowing locally accumulated heat to dissipate quickly and reducing the long-term residence of heat in a certain area. This reduces the risk of the material softening due to local overheating. Furthermore, the protruding structure of the reinforcing protrusions 2 can also improve the overall rigidity of the tray body 1 and enhance its resistance to bending and deformation in high-temperature environments. Several reinforcing protrusions 5 are set in the rectangular grooves on the bottom wall of the storage slot 4 to strengthen the deformation resistance of the bottom of the storage slot 4, thereby reducing the deformation of the storage slot 4.

[0022] In this embodiment, as Figure 1 and 3 As shown, several reinforcing ridges 5 are evenly spaced inside the rectangular groove, and the top of the reinforcing ridges 5 is flush with the bottom wall of the storage groove 4. In use, the evenly spaced reinforcing ridges 5 inside the rectangular groove can make the bottom of the storage groove 4 more evenly stressed, avoiding local deformation caused by uneven stress. The flushness between the top of the reinforcing ridges 5 and the bottom wall of the storage groove 4 can not only ensure the flatness of the bottom of the storage groove 4, making it easy to place items, but also enhance the structural strength of the storage groove 4.

[0023] In this embodiment, as Figure 1 As shown, the upper surface of the tray body 1 is provided with a pick-up and put-down slot 6 on the outer side of the storage slot 4. The inner wall of the pick-up and put-down slot 6 is provided with an arc-shaped block 7. When in use, the pick-up and put-down slot 6 facilitates the user to pick up and put down items, provides a point of leverage, and makes it easy to pick up the tray or remove items from the tray. The arc-shaped block 7 is used to enhance the structural strength of the pick-up and put-down slot 6.

[0024] In this embodiment, as Figure 3 and 4 As shown, a plug rod 11 is fixedly connected to the bottom of the tray body 1. A cross block 12 is provided at the lower end of the plug rod 11. A plug hole 9 for inserting the plug rod 11 is provided on the upper surface of the tray body 1. A cross hole 10 is provided on the bottom wall of the plug hole 9. In use, multiple tray bodies 1 can be stacked together through the cooperation between the plug rod 11, the plug hole 9, the cross block 12 and the cross hole 10.

[0025] In this embodiment, as Figure 1-4 As shown, the number of insertion holes 9, cross holes 10, insertion rods 11 and cross blocks 12 are the same and correspond one-to-one. The outer diameter of the insertion rod 11 is adapted to the inner diameter of the insertion hole 9, and the outer dimensions of the cross block 12 are adapted to the inner wall space dimensions of the cross hole 10. In use, it can achieve precise positioning and stable connection between the pallet bodies 1, and prevent the pallet bodies 1 from being misaligned or tipped over when stacked.

[0026] In this embodiment, as Figure 2 As shown, the pallet body 1 has symmetrically arranged transport grooves 8 on both outer walls. During use, these grooves provide convenient gripping points for transporting the pallet body 1, making it easier for workers to transport the pallet body 1. Especially when transporting heavy items or transporting in batches, these grooves can effectively reduce the difficulty of transporting and improve transport efficiency.

[0027] The working principle of this application is as follows: When using the heat-resistant blister tray of this application, the tray body 1 is injection molded from polypropylene material, which makes the tray body 1 highly heat-resistant. The reinforcing protrusions 2 on the upper surface of the tray body 1 form several air circulation grooves 3. These air circulation grooves 3 provide channels for air flow. When the tray body 1 comes into contact with high-temperature products or heat sources, the air can naturally convect in the air circulation grooves 3, so that the locally accumulated heat can be quickly dissipated, reducing the long-term residence of heat in a certain area, thereby reducing the risk of the material softening due to local overheating. The raised structure of the reinforcing protrusions 2 improves the overall rigidity of the tray body 1 and enhances the bending and deformation resistance of the tray body 1 in high-temperature environments. Several reinforcing protrusions 5 are set in the rectangular grooves on the bottom wall of the storage groove 4 to strengthen the deformation resistance of the bottom of the storage groove 4, thereby reducing the deformation of the storage groove 4.
