Description
- The present invention relates to a thermal box, and more particularly to a thermal container.
- Thermal containers are containers having thermal insulation properties. In our daily life, thermal boxes are widely used, especially in the fields of take-away food, medicine, scientific research, etc. for carrying articles that need to be kept in a constant temperature environment. Compared with a general storage box, the main body of a thermal box is made of special materials to attain a thermal function, so that the main body has a short-term thermal effect for storing food, medicines, samples, and the like and for maintaining the temperature and freshness of the above items.
- The material of the main body of a conventional thermal box emphasizes its thermal insulation performance and can play a certain role in shaping. The load-bearing capacity of the overall structure is poor. Once a heavier object is placed on the top of the thermal box, it will cause the thermal box to deform or even collapse.
- The primary object of the present invention is to provide a thermal container with high load-bearing capacity to ensure that the overall structure is stable and not deformed.
- In order to achieve the above object, the present invention adopts the following technical solutions.
- A thermal container comprises a cover, a main body, an opening-closing assembly, and a plurality of support poles. The main body has a storage space therein. The opening-closing assembly includes an upper connecting member and a lower connecting member. The lower connecting member is hermetically connected to an opening of the storage space. The lower connecting member has a through hole communicating with the storage space. The upper connecting member is hermetically connected to the cover. The upper connecting member is provided with a protruding portion matching the through hole. The protruding portion is movably, hermetically fitted in the through hole. The support poles are vertically arranged in the main body. Upper ends of the support poles support an underside of the lower connecting member. The support poles, the upper connecting member and the lower connecting member are made of a hard material.
- Preferably, the cover and the upper connecting member as well as the main body and the lower connecting member are connected in a sealed manner by bonding.
- Preferably, the cover includes a first outer layer, a first interlayer and a first inner layer that are stacked in sequence.
- Preferably, the main body includes a second outer layer, a second interlayer and a second inner layer that are stacked in sequence. The support poles are arranged between the second outer layer and the second inner layer.
- Preferably, the main body is in the form of a box. The number of the support poles is four, and the four support poles are arranged at four corners of the main body, respectively.
- Preferably, the second interlayer after being folded is formed with pole cavities at corner positions of the second interlayer for the support poles to be fitted therein.
- Preferably, a side wall of each support pole is formed with a groove for insertion of the second interlayer.
- Preferably, rear ends of the upper connecting member and the lower connecting member are pivotally connected together, and front ends of the upper connecting member and the lower connecting member are provided with a locking mechanism. The locking mechanism includes a hook disposed on the front end of the upper connecting member and a catching portion disposed on the front end of the lower connecting member. When the upper connecting member and the lower connecting member are closed, the hook is buckled to the catching portion.
- Preferably, the opening-closing assembly further includes a sealing ring. A side wall of the through hole is provided with an annular step. One side of the step, facing the protruding portion, is formed with an annular flange. The sealing ring is fitted onto the flange.

support poles 3 to be fitted in themain body 2 as long as thesupport poles 3 are always perpendicular to the lower connectingmember 5 without shaking.FIG. 5 shows the first implementation of thesupport poles 3 in this embodiment. Thesecond interlayer 23 after being folded is formed withpole cavities 231 at corner positions of thesecond interlayer 23 for thesupport poles 3 to be fitted therein. That is, thesecond interlayer 23 is used to fill the periphery of eachsupport pole 3 to prevent the position of thesupport pole 3 from changing or to prevent thesupport pole 3 from shaking.FIG. 6 shows the second implementation of thesupport poles 3 in this embodiment. Eachsupport pole 3 is formed with agroove 31 for insertion of thesecond interlayer 23. That is, thesecond interlayer 23 is retained by the side walls of thesupport poles 3, so that the two are held in place. - The locking mechanism includes a
hook 6 disposed on the front end of the upper connectingmember 4 and a catchingportion 53 disposed on the front end of the lower connectingmember 5. When the upper connectingmember 4 and the lower connectingmember 5 are closed, thehook 6 is buckled to the catchingportion 53, so that the front end of the upper connectingmember 4 is fastened to the front end of the lower connectingmember 5. In this embodiment, thehook 6 is pivotally connected to the front end of the upper connectingmember 4. The front end of the lower connectingmember 5 is formed with arecess 54. The catchingportion 53 is disposed in therecess 54. After the upper connectingmember 4 and the lower connectingmember 5 are closed, thehook 6 is located in therecess 54 and will not extend beyond the front ends of the upper connectingmember 4 and the lower connectingmember 5, keeping the front ends of the upper connectingmember 4 and the lower connectingmember 5 flat. That is, the surface of the thermal container is flat. - The opening-closing assembly further includes a
sealing ring 7. The side wall of the throughhole 51 is provided with anannular step 55. One side of thestep 55, facing the protrudingportion 41, is formed with anannular flange 56. The sealingring 7 is fitted onto theflange 56. When the upper connectingmember 4 and the lower connectingmember 5 are closed, the protrudingportion 41 is in contact with the sealingring 7 and compresses the sealingring 7 to be deformed, so as to maintain airtightness between the protrudingportion 41 and thestep 55. The sealingring 7 is secured on theflange 56 of thestep 55. The sealingring 7 is not easy to loose when the opening-closing assembly is closed or opened. Theflange 56 abuts on thesealing ring 7 to deform thesealing ring 7, and the stressed area is small. The sealingring 7 is more fully deformed and has a better sealing effect. In this embodiment, the sealingring 7 is adhered to theflange 56. The sealingring 7 is made of PVC, TPU, TPR, rubber or silicone. - The hard material is an injection moldable plastic material.
- In practical applications, the
main body 2 is generally made into the shape of a box or bag. Of course, in the present invention, the thermal container may be designed into two separate parts in other forms. - By adopting the above solutions, in the present invention, the upper connecting
member 4 and the lower connectingmember 5 serve as the frame of the thermal container. Thesupport poles 3 support the underside of the lower connectingmember 5. The upper connectingmember 4 can increase the supporting strength of thecover 1, and the lower connectingmember 5 and thesupport poles 3 can increase the supporting strength of themain body 2, so that the thermal container has a higher load-bearing capacity.
