Description

Technical Field

[0001] This utility model relates to the field of thermal insulation foam boxes, and more specifically, to a refrigerated thermal insulation foam box with a leak-proof sealing groove. Background Technology

[0002] In the transportation and storage of fresh food, biological agents and other items that require refrigeration, refrigerated insulated foam boxes are widely used due to their good insulation performance, lightweight and cost advantages. Refrigerated insulated foam boxes on the market can be divided into various types according to different sizes.

[0003] Patent CN110641808A discloses a foam box comprising an outer layer, a middle layer, and an inner layer. The outer layer is made of EPP or EPO; the middle layer is made of EPS; and the inner layer is made of EPS. This invention solves the problem of the inner layer not shedding lint, ensuring the cleanliness of glass products; enhances the impact resistance of the outer layer, making it less prone to damage during packaging and transportation, and increasing the number of recycling cycles; improves the stiffness and strength of the foam box, making it less prone to bending during handling; and reduces packaging costs.

[0004] While this technical solution has its advantages, most current refrigerated insulated foam boxes still have some shortcomings in use. For example, when the refrigerated items inside are ice packs, if the ice packs melt, seafood leaks juices, or the packaging of biological agents breaks, the liquid can easily leak from the gaps in the box. This can not only contaminate other items inside the box but also potentially pollute the transportation vehicle and storage environment, increasing cleaning costs and hygiene risks. Secondly, ordinary foam boxes have a simple sealing structure and poor sealing performance, allowing external heat to easily enter the box, causing the internal temperature to rise and making it impossible to maintain a low-temperature environment for a long time, seriously affecting the quality and shelf life of refrigerated items. Therefore, developing a refrigerated insulated foam box with highly efficient leak-proof function and enhanced sealing and insulation effect is of significant practical importance. Utility Model Content

[0005] The purpose of this invention is to provide a refrigerated insulated foam box with a leak-proof sealing groove to solve the defects mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A refrigerated insulated foam box with a leak-proof sealing groove includes a foam box body. A rectangular ring-shaped sealing groove is provided on the top surface of the foam box body. A foam box lid is provided on the top of the foam box body. A central reinforcing strip is fixedly installed on the bottom surface of the foam box lid, directly opposite the sealing groove. A sealing strip is fixedly installed on the outside of the central reinforcing strip. The sealing strip is located within the sealing groove and engages with it. A sealing gasket is fixedly installed between the inner side of the sealing strip and the bottom surface of the foam box lid. The sealing gasket is pressed tightly against the top surface of the foam box body.

[0008] Preferably, the cross-section of the sealing groove is narrow at the bottom and wide at the top, the lower half of the cross-section of the sealing groove is rectangular, and the upper half of the cross-section of the sealing groove is an isosceles trapezoid.

[0009] This setting allows the sealing strip to be better inserted into the sealing groove to achieve the sealing operation.

[0010] Preferably, the width of the sealing strip is equal to the width of the lower half of the sealing groove, and the height of the sealing strip is greater than the depth of the sealing groove.

[0011] Preferably, after the foam box lid is closed downwards, the bottom surface of the foam box lid abuts against the top surface of the foam box body, and the sealing strip fills the entire sealing groove;

[0012] The above two settings can improve the sealing effect and prevent leakage.

[0013] Preferably, the foam box has a storage chamber with its top connected to the outside, and a rectangular ring-shaped bottom positioning frame is fixedly installed on the bottom surface of the foam box cover. The bottom positioning frame is located inside the storage chamber and is inserted into the storage chamber.

[0014] Preferably, the cross-section of the bottom positioning frame is an isosceles trapezoidal shape, and the outer diameter of the bottom positioning frame decreases sequentially from top to bottom;

[0015] The above two settings enable positioning operations after the foam box lid is closed.

[0016] Preferably, the outer side surface of the foam box cover near one end of the foam box body is provided with a side slope, and the outer side surface of the central reinforcing strip is provided with a side anti-scratch frame. The side anti-scratch frame is used to protect the sealing strip after the knife scratches along the side slope.

[0017] The beveled side of this feature makes it easier to use a knife to cut through the sealing tape and open the foam box lid. The anti-scratch frame on the side can prevent the knife from being inserted too deeply and damaging the sealing strip.

[0018] Preferably, the bottom wall of the sealing groove is provided with two symmetrical lower grooves, and a water-absorbing and expanding rubber strip is fixedly installed in the lower groove.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. This utility model achieves a tight connection and efficient seal between the foam box body and the foam box lid through a sealing structure composed of a sealing groove, a sealing strip, and a sealing gasket, in conjunction with a water-absorbing and expanding strip in the lower groove. The unique cross-sectional design of the sealing groove, which is narrow at the bottom and wide at the top, allows the sealing strip to be better inserted into it. After the foam box lid is closed, the sealing strip fills the groove, and with the compression of the sealing gasket, it effectively prevents external heat from entering. The water-absorbing and expanding strip expands when it comes into contact with liquid, further filling the gaps and preventing liquid leakage inside the box. This avoids contaminating the items inside the box, transportation vehicles, and the storage environment, and reduces cleaning costs and hygiene risks.

[0021] 2. This utility model achieves precise positioning when the foam box lid is closed by setting a bottom positioning frame on the bottom surface of the foam box lid and inserting it into the storage chamber inside the foam box. The bottom positioning frame is in the shape of a specific isosceles trapezoid. Compared with ordinary foam boxes, this design not only makes it easier and more accurate to close the lid, but also enhances the stability of the overall structure, ensuring that the sealing structure always maintains a good condition during use, and further improving the sealing and heat preservation performance of the foam box.

[0022] 3. This utility model, by setting a side bevel at the end of the foam box lid and a side anti-scratch frame on the outer side of the central reinforcing strip, facilitates the operation of opening the foam box lid by cutting the sealing tape with a knife, while effectively protecting the sealing strip from damage by the knife. This design takes into account both ease of use and the integrity of the sealing strip, extends the service life of the foam box, and ensures that it always has good leak-proof and heat-insulating capabilities during repeated use.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0030] Please see Figures 1-3 This utility model provides a technical solution: a refrigerated and insulated foam box with a leak-proof sealing groove, including a foam box body 1. A rectangular ring-shaped sealing groove 11 is provided on the top surface of the foam box body 1. A foam box cover 2 is provided on the top of the foam box body 1. A central reinforcing strip 22 is fixedly installed on the bottom surface of the foam box cover 2, directly opposite the sealing groove 11. A sealing strip 24 is fixedly installed on the outside of the central reinforcing strip 22, and the sealing strip 24 is located inside the sealing groove 11 and engages with it. A sealing gasket 25 is fixedly installed between the inner side of the sealing strip 24 and the bottom surface of the foam box lid 2. The sealing gasket 25 is pressed against the top surface of the foam box body 1, so that the sealing strip 24 is inserted into the sealing groove 11. The sealing gasket 25 is pressed against the top surface of the foam box body 1, forming a multi-layer sealing structure. Compared with the single sealing method of traditional foam boxes, this structure effectively prevents outside air from entering the foam box body 1, greatly improves the sealing performance of the foam box, reduces the loss of cold air inside the box, and ensures the storage environment of refrigerated items.

[0031] like Figure 2 As shown, the sealing groove 11 has a cross-section that is narrower at the bottom and wider at the top. The lower half of the cross-section of the sealing groove 11 is rectangular, while the upper half is an isosceles trapezoidal shape, allowing the sealing strip 24 to be inserted more smoothly and tightly into the sealing groove 11. This special shape design increases the contact area and friction between the sealing strip 24 and the sealing groove 11, making the sealing strip 24 less likely to fall off or shift, thus achieving a more reliable sealing operation and further enhancing the sealing effect of the foam box.

[0032] In this embodiment, the width of the sealing strip 24 is equal to the width of the lower half of the sealing groove 11, and the height of the sealing strip 24 is greater than the depth of the sealing groove 11. After the foam box cover 2 is closed downwards, the bottom surface of the foam box cover 2 abuts against the top surface of the foam box 1, and the sealing strip 24 fills the entire sealing groove 11. This setting fills all the gaps in the sealing groove 11, eliminating gaps that may lead to liquid or air leakage. Compared with the cooperation of ordinary sealing strips and grooves, the sealing effect is significantly improved, effectively avoiding liquid leakage and heat exchange.

[0033] like Figure 1 and Figure 2 As shown, the foam box 1 has a storage chamber 10 with its top connected to the outside. A rectangular ring-shaped bottom positioning frame 20 is fixedly installed on the bottom surface of the foam box lid 2. The bottom positioning frame 20 is located inside the storage chamber 10 and is inserted into the storage chamber 10. The cross-section of the bottom positioning frame 20 is an isosceles trapezoidal shape, and the outer diameter of the bottom positioning frame 20 decreases from top to bottom, achieving precise positioning when the foam box lid 2 is closed. When installing the foam box lid 2, this design guides the lid to accurately cover the foam box 1, avoiding the problem of poor sealing due to misalignment, and also making the overall structure of the foam box more stable.

[0034] like Figure 2 As shown, a side slope 21 is provided on the outer side of one end of the foam box lid 2 near the foam box body 1, and a side anti-scratch frame 23 is provided on the outer side of the central reinforcing strip 22. The side anti-scratch frame 23 is used to protect the sealing strip 24 after the knife is cut along the side slope 21. This allows the operator to easily cut the sealing tape with the knife along the side slope 21 and open the foam box lid 2. At the same time, the side anti-scratch frame 23 can prevent the knife from being inserted too much and protect the sealing strip 24, preventing the sealing strip 24 from being damaged during the opening process, and ensuring that the foam box can still maintain good sealing performance after multiple uses.

[0035] like Figure 3 As shown, the bottom wall of the sealing groove 11 is provided with two symmetrical lower grooves 12. Water-absorbing and expanding rubber strips 121 are fixedly installed in the lower grooves 12. When liquid leaks into the box, the liquid flows into the sealing groove 11. When the liquid comes into contact with water, the water-absorbing and expanding rubber strips 121 expand and fill the gaps in the sealing groove 11, further preventing liquid leakage. Compared with foam boxes without water-absorbing and expanding rubber strips 121, this setting provides an extra guarantee against leakage. Even if there are small gaps in the sealing strip 24, the water-absorbing and expanding rubber strips 121 can effectively prevent liquid seepage and protect the items in the box and the transportation environment.

[0036] It is worth noting that the water-absorbing and expanding adhesive strip 121 can be made of a superabsorbent polymer (SAP) material. SAP material rapidly expands to form a gel after absorbing water and has excellent water retention properties, resisting water loss even under pressure. When made into an SAP material, it can quickly absorb a large amount of water and expand to tightly fill the gaps in the sealing groove when liquid leaks inside the foam box, effectively preventing leakage. Furthermore, SAP is chemically stable and does not readily react with common liquids found in refrigerated items, ensuring high safety.

[0037] When using the refrigerated and insulated foam box with a leak-proof sealing groove, first place the items that need to be refrigerated into the storage chamber 10 of the foam box body 1. If the items may leak liquid, protective measures can be taken in advance. Then, lift the foam box lid 2 and align the bottom positioning frame 20 with the storage chamber 10. Since the bottom positioning frame 20 is in the shape of an isosceles trapezoid and the outer diameter decreases from top to bottom, the foam box lid 2 can be quickly and accurately positioned on the foam box body 1.

[0038] Then, the foam box lid 2 is slowly lowered, allowing the sealing strip 24 to be embedded in the sealing groove 11. The size design of the sealing strip 24 enables it to tightly fill the sealing groove 11, while the sealing gasket 25 is pressed against the top surface of the foam box 1, forming a multi-layer sealing structure.

[0039] Finally, confirm that the foam box lid 2 is completely closed, and then use tape to fix the foam box body 1 and the foam box lid 2 together. During transportation or storage, if there is liquid leakage inside the box, the sealing strip 24 can prevent leakage. If leakage occurs at the sealing strip 24, the liquid flowing into the sealing groove 11 will cause the water-absorbing and expanding strip 121 to expand when it comes into contact with water, further enhancing the leak-proof effect.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
