Description

Technical Field

[0001] This utility model relates to the field of lunch box technology, and in particular to a pulp-separated lunch box. Background Technology

[0002] Pulp-separated lunch boxes are disposable lunch boxes made from renewable raw materials such as waste paper and plant fibers through pulping and molding. The boxes have a partition structure inside, which can separate different foods to avoid cross-contamination of flavors. Because the raw materials are biodegradable, they can easily decompose naturally after being disposed of.

[0003] When the body and lid of existing pulp-separated lunch boxes are connected, the porous nature of pulp makes it difficult to form a completely sealed structure at the joint. Furthermore, irregular edges are prone to occur during the molding process, resulting in tiny gaps at the joint. This allows food inside to lose heat quickly, affecting the taste and potentially causing soup or oil to leak through the gaps, contaminating hands or the outer packaging. In addition, pulp has a high thermal conductivity, and to ensure formability and cost control, the bottom of the lunch box is usually designed to be thin without dedicated insulation. When hot food is inside, heat is quickly conducted through the bottom to the outer surface, causing the surface temperature to rise. Direct contact with hands can easily result in burns, and the lunch box cannot be held directly without additional insulation, increasing inconvenience. Utility Model Content

[0004] The purpose of this utility model is to provide a pulp-separated lunch box. The second outer skirt of the box lid is engaged with the teardrop-shaped slot of the first outer skirt of the lunch box body through an insert block. With the deformation and contact of the sealing plates on both sides of the insert block, the sealing performance between the box body and the box lid can be improved, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A pulp-separated lunch box includes a lunch box body and a lid. A first outer skirt is fixedly connected to the outer side of the lunch box body. The lunch box body also includes multiple partition boxes. Multiple reinforcing ribs are provided on the outer side of each partition box. A heat-insulating layer is provided at the bottom of each partition box. A second outer skirt is fixedly connected to the outer side of the lid. An insert is fixedly connected to the bottom of the second outer skirt. Sealing sheets are fixedly connected to both the outer and inner sides of the insert. The second outer skirt is snapped onto the first outer skirt.

[0007] As a further preferred embodiment of this utility model, a support plate is fixedly connected between two adjacent compartments. This can prevent the connection between the two adjacent compartments from deforming downwards due to gravity after food is placed in the compartments, thus preventing multiple compartments from drooping and affecting handholding. At the same time, it can also prevent the first outer skirt from separating from the second outer skirt due to the drooping of the compartments, which would cause poor sealing.

[0008] As a further preferred embodiment of this utility model, a slot is provided inside the first outer skirt, and the longitudinal section of the slot is teardrop-shaped.

[0009] As a further preferred embodiment of this utility model, the longitudinal section of the insert is the same as the longitudinal section of the slot. The insert is snapped into the slot, and the bottom of the sealing sheet deforms and abuts against the first outer skirt. After the insert and the slot are snapped together, the connection between the lunch box body and the box lid can be achieved through the snapping of the first outer skirt and the second outer skirt. In addition, the sealing sheet increases the contact area with the first outer skirt, fills the tiny gaps, and can also continuously apply pressure through arc elasticity to reduce leakage channels, thereby improving the sealing performance.

[0010] As a further preferred embodiment of this utility model, the heat-insulating layer is a natural plant fiber coating; after coating, it forms a porous heat-insulating structure, slows down heat transfer, makes it easy to hold the lunch box body by hand, and is easily degradable after disposal.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] In this invention, the second outer skirt of the lid is engaged with the teardrop-shaped slot of the first outer skirt of the food container body via an insert block. Combined with the deformation and contact of the sealing plates on both sides of the insert block, the sealing performance between the container body and the lid is greatly improved, reducing food temperature loss, soup leakage, and odor overflow. Furthermore, the reinforcing ribs on the outer side of the separating container body and the adjacent support plate enhance the structural strength, preventing the separating container body from sagging after food is served, which could lead to skirt separation and seal failure. The natural plant fiber heat-insulating layer at the bottom of the separating container body slows down heat transfer, allowing the container to be held directly by hand, thus combining environmental protection and practicality.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figures 1-5 As shown, the present invention provides a pulp-separated lunch box, including a lunch box body 1 and a lid 2. A first outer skirt 3 is fixedly connected to the outside of the lunch box body 1. The lunch box body 1 also includes multiple partition boxes 4. Multiple reinforcing ribs 5 are provided on the outside of the partition boxes 4. A heat-insulating layer 9 is provided at the bottom of the partition boxes 4. A second outer skirt 6 is fixedly connected to the outside of the lid 2. An insert 7 is fixedly connected to the bottom of the second outer skirt 6. Sealing sheets 8 are fixedly connected to both the outside and inside of the insert 7. The second outer skirt 6 is snapped onto the first outer skirt 3.

[0021] like Figure 2 As shown, a support plate 10 is fixedly connected between two adjacent compartments 4. This prevents the connection between the two adjacent compartments 4 from deforming downwards due to gravity after food is placed in the compartments 4, thus preventing multiple compartments 4 from drooping and affecting hand handling. At the same time, it also prevents the first outer skirt 3 from separating from the second outer skirt 6 due to the drooping of the compartments 4, which would cause a poor seal.

[0022] like Figures 2-3 As shown, a slot 11 is provided in the first outer skirt 3. The longitudinal section of the slot 11 is teardrop-shaped. The longitudinal section of the insert 7 is the same as that of the slot 11. The insert 7 is snapped into the slot 11. The bottom of the sealing sheet 8 deforms and abuts against the first outer skirt 3. After the insert 7 and the slot 11 are snapped together, the connection between the lunch box body 1 and the lid 2 can be achieved through the snapping of the first outer skirt 3 and the second outer skirt 6. In addition, the sealing sheet 8 increases the contact area with the first outer skirt 3, fills the tiny gaps, and can continuously apply pressure through the arc elasticity to reduce leakage channels, thereby improving the sealing performance.

[0023] like Figure 5 As shown, the heat-insulating layer 9 is a natural plant fiber coating; after coating, it forms a porous heat-insulating structure, slows down heat transfer, makes it easy to hold the lunch box body 1 with your hand, and is easily degradable after disposal.

[0024] It should be noted that this utility model is a pulp-divided lunch box. In use, different types of food are first placed into the respective dividers 4 of the lunch box body 1. The dividers 4 allow for separate food storage. After food is placed in the dividers 4, the support plates 10 between adjacent dividers 4 provide support, preventing the dividers 4 from deforming downwards at the connection points due to gravity after being filled with food. Then, the lid 2 is placed on the lunch box body 1, so that the second outer skirt 6 of the lid 2 corresponds to and engages with the first outer skirt 3 of the lunch box body 1, and the insert 7 at the bottom of the second outer skirt 6 is aligned with the inside of the first outer skirt 3. The insert 7 is inserted into the slot 11. Since the longitudinal section of the insert 7 is the same as the longitudinal section of the teardrop-shaped slot 11, the insert 7 can be stably engaged in the slot 11, thus connecting the lunch box body 1 and the lid 2. During the process of inserting the insert 7 into the slot 11, the sealing pieces 8 on the outer and inner sides of the insert 7 will gradually come into contact with the first outer skirt 3 and deform. The deformed sealing pieces 8 will tightly abut against the first outer skirt 3, which not only increases the contact area with the first outer skirt 3, but also continuously applies pressure to the first outer skirt 3 through its own arc elasticity, filling the tiny gap between the insert 7 and the slot 11, reducing leakage channels, thereby greatly improving the sealing performance of the lunch box body 1 and the lid 2.

[0025] The heat-insulating layer 9 at the bottom of the partition box 4 is a natural plant fiber coating. Its porous heat-insulating structure can slow down the transfer of heat from hot food to the outside of the food box and reduce the temperature of the outer surface of the food box. This allows users to directly hold the food box body 1 with their hands without the need for additional heat-insulating tools, improving ease of use. In addition, the natural plant fiber coating is easily degradable after disposal, meeting environmental protection requirements.

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 illustrative of the principles of this utility model.
