Description

Technical Field

[0001] This utility model relates to the field of modular plastic lunch boxes, specifically to a modular plastic lunch box with good heat preservation effect. Background Technology

[0002] Plastic lunch boxes are plastic containers made of food-grade plastic materials, designed to make it convenient for us to bring food out. They are a common household plastic product and an indispensable plastic container for picnics or hikes.

[0003] Current modular plastic lunch boxes have a relatively simple structure and only serve the function of basic food storage. They are generally insulated by a single insulated bag, which has poor insulation performance. In addition, the sealing performance of modular lunch boxes is poor. When tilted or overturned, the juices of various foods inside can easily leak out and mix, leading to cross-contamination of flavors.

[0004] Accordingly, this utility model proposes a modular plastic lunch box with good heat preservation effect. Utility Model Content

[0005] To overcome the shortcomings of the prior art, this utility model provides a modular plastic lunch box with good heat preservation effect. The action of closing the lid seals the storage chamber and the inner lunch box separately. At the same time, the sealing bolts enhance the tightness and stability of the lid, ensuring the sealing effect between the storage chamber and the inner lunch box and preventing the food inside from flowing out and mixing when the lunch box is turned upside down. It also has a water storage space, and the addition of hot water can extend the heat preservation time of the lunch box.

[0006] Technical solution

[0007] A modular plastic lunch box with good heat preservation includes a box body. The lower interior of the box body has two storage chambers, and the upper surface of each storage chamber has an upper space. A step is provided between the upper space and the storage chambers. A sealing partition is placed on the step. Two limiting rings are provided on the upper surface of the sealing partition, and an inner lunch box is placed on the limiting rings. A lid is provided at the top of the box body. The lower surface of the lid has a rubber layer for sealing the inner lunch box and a compression part for compressing and sealing the sealing partition. A heat preservation mechanism is also provided inside the box body.

[0008] Furthermore, the stepped portion is provided with an extrusion sealing rib, and the lower surface of the sealing partition is provided with a groove for adapting to the extrusion sealing rib.

[0009] Furthermore, the heat preservation mechanism includes a water storage space located on the side and bottom of the box body for pouring in hot water for heat preservation, and the upper end of the water storage space is provided with a threaded opening.

[0010] Furthermore, a threaded plug is screwed into the threaded opening.

[0011] Furthermore, the upper side of the box body is provided with a threaded hole, and a sealing bolt that can be screwed into the threaded hole passes through the box cover.

[0012] Furthermore, the lid is also provided with a gripper.

[0013] Beneficial effects

[0014] Compared with the prior art, this utility model has the following advantages: the action of closing the lid seals the storage chamber and the inner food container separately, and the sealing bolts enhance the tightness and stability of the lid, ensuring the sealing effect between the storage chamber and the inner food container and preventing the food from leaking out and mixing when the food container is turned upside down; at the same time, a water storage space is provided, and the filling of hot water can extend the heat preservation time of the food container; the presence of the limiting ring not only ensures the stability of the inner food container, but also facilitates the removal of the sealing partition.

Detailed Implementation

[0018] To better illustrate the content of this utility model, the following description is provided in conjunction with the accompanying drawings and embodiments:

[0019] have Figure 1 As shown, this utility model discloses a modular plastic lunch box with good heat preservation effect, including a box body 1. The lower side of the box body 1 is provided with two storage chambers 2. The upper side of the storage chambers 2 is provided with an upper space 18. A step 19 is provided between the upper space 18 and the storage chambers 2. A sealing partition 16 is placed on the step 19. The upper side of the sealing partition 16 is provided with two limiting rings 15. An inner lunch box 6 is placed on the limiting rings 15. The upper part of the box body 1 is provided with a box lid 12. The lower side of the box lid 12 is provided with a rubber layer 10 for sealing the inner lunch box 6 and a squeezing part 14 for squeezing and sealing the sealing partition 16. A heat preservation mechanism 900 is also provided inside the box body 1.
