Description

Technical Field

[0001] This utility model relates to the field of blister box technology, and more specifically, to a food blister box with good sealing performance. Background Technology

[0002] Blister boxes are a type of plastic packaging material primarily used to protect and display various goods. They are made using a vacuum forming process where a flat sheet of rigid plastic is heated until it softens, then vacuum-formed onto a mold surface, and finally cooled to form the desired shape. Blister boxes can be designed in various shapes and sizes to meet different needs. Common materials include PVC, PS, and PET. Blister boxes are widely used in multiple industries, including food, electronics, toys, and cosmetics. In the food industry, blister boxes are commonly used to package vegetables, fruits, meat, dairy products, candy, and biscuits, helping to maintain the freshness and hygiene of the food.

[0003] Patent publication number CN210943052U discloses a blister packaging box for food. A cushioning layer wraps around the outside of the blister packaging body, and an outer packaging layer wraps around the cushioning layer. A first packaging body and a second packaging body are connected on one side edge and are snapped together. The first packaging body has a first storage groove and a first raised strip, which are adjacent to each other. The second packaging body has a second storage groove and a second raised strip, which are adjacent to each other. The first and second storage grooves are staggered, as are the first and second raised strips. Ribs are also provided on both the first and second packaging bodies. Through this method, the present invention can reduce packaging costs, effectively protect the packaged food from being squeezed or broken, reduce the use of blister packaging materials, enhance packaging strength, reduce packaging waste, and is environmentally friendly.

[0004] However, the blister packaging boxes in patent publication number CN210943052U usually use soft material for the edges, which makes it easy to open the blister box by pressing down or lifting up. Although this method is relatively convenient, the sealing and heat preservation effects of such blister boxes are poor. Therefore, we propose a food blister box with good sealing performance to solve the above-mentioned problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0031] Example:

[0032] Please see Figure 1-5 A food blister box with good sealing performance includes a blister box body 1 and a lid 2 that is detachably connected to the top of the blister box body 1. The lower surface edge of the lid 2 is integrally formed with a flange 3. The bottom of the flange 3 is provided with a sealing groove 4 with a wedge-shaped structure. The inner side of the sealing groove 4 is respectively inlaid with a first sealing ring 5 and a second sealing ring 6.

[0033] The upper surface edge of the lid 2 is symmetrically provided with slots 10;

[0034] A connecting seat 7 is fixedly connected to the outer wall of the blister box body 1 near the slot 10. A connecting frame 8 is rotatably connected to the connecting seat 7. A pressure block 9 that engages with the slot 10 is installed at the end of the connecting frame 8.

[0035] It should be noted that when using this well-sealed food blister box, after placing the food inside the blister box body 1, the lid 2 is assembled onto the blister box body 1, so that the sealing groove 4 set at the flange 3 is aligned with the top edge of the blister box body 1. By rotating the connecting bracket 8 installed on the connecting seat 7, the pressure block 9 is engaged with the slot 10. Because the sealing groove 4 is set in a wedge shape, as the sealing groove 4 is gradually pressed down, the first sealing ring 5 and the second sealing ring 6 can fit tightly against the inner and outer walls of the top opening of the blister box body 1, thereby improving the heat preservation and sealing effect of the blister box body 1.

[0036] like Figure 4 As shown, the sealing groove 4 is connected to the top edge of the blister box body 1, and the bottom opening size of the sealing groove 4 is smaller than the top opening thickness of the blister box body 1. The first sealing ring 5 and the second sealing ring 6 are tightly fitted to the outer wall and inner wall of the top opening of the blister box body 1, respectively.

[0037] It should be noted that because the sealing groove 4 is set in a wedge shape, as the sealing groove 4 is gradually pressed down, the first sealing ring 5 and the second sealing ring 6 can fit tightly against the inner and outer walls of the top opening of the blister box body 1, thereby improving the heat preservation and sealing effect of the blister box body 1.

[0038] like Figure 1 , Figure 2 As shown, both ends of the card slot 10 have notches corresponding to the connecting bracket 8;

[0039] It should be noted that when the pressure block 9 and the slot 10 are engaged, the connecting bracket 8 is inserted into the notch to avoid interference between the connecting bracket 8 and the cover 2.

[0040] like Figure 1 , Figure 2As shown, the pressure block 9 is cylindrical, the slot 10 is arc-shaped, and the inner diameter of the slot 10 is matched with the outer diameter of the pressure block 9.

[0041] It should be noted that this facilitates the engagement between the pressure block 9 and the slot 10, and also facilitates the separation between the pressure block 9 and the slot 10.

[0042] like Figure 1 As shown, the outer wall of the blister box body 1 near the connecting seat 7 is integrally formed with anti-slip protrusions 11, and multiple anti-slip protrusions 11 are arranged longitudinally at equal intervals.

[0043] It should be noted that by setting anti-slip protrusions 11 on the outer wall of the blister box body 1, the friction resistance on the outer side of the blister box body 1 can be effectively increased, thereby ensuring a good anti-slip effect when the operator holds the blister box body 1 and cleans it.

[0044] like Figure 5 As shown, a boss 12 is provided around the bottom edge of the blister box body 1, and the boss 12 and the blister box body 1 are integrally formed.

[0045] It should be noted that by setting a protrusion 12 at the bottom of the blister box body 1, the food inside the blister box body 1 can be effectively prevented from overheating and causing burns to the table.

[0046] In use: After placing the food inside the blister box body 1, assemble the lid 2 onto the blister box body 1, so that the sealing groove 4 set at the flange 3 is aligned with the top edge of the blister box body 1. By rotating the connecting bracket 8 installed on the connecting seat 7, the pressure block 9 is engaged with the slot 10. Because the sealing groove 4 is set in a wedge shape, as the sealing groove 4 is gradually pressed down, the first sealing ring 5 and the second sealing ring 6 can fit tightly against the inner and outer walls of the top opening of the blister box body 1.

[0047] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
