Description

Technical Field

[0001] The utility model belongs to the technical field of fast food boxes, and in particular relates to a takeaway packaged lunch box. Background Art

[0002] As the pace of society accelerates, the dining habits of the younger generation have entered a fast-paced mode, and various problems caused by takeout delivery and taking meals out have become increasingly prominent. For fried and pan-fried foods, due to the poor ventilation of disposable lunch boxes, the lunch boxes will be filled with water vapor emitted by the food after a period of time, causing the fried and pan-fried foods to no longer be crispy and unable to maintain their original taste. If only ventilation holes are made on the lunch box, its heat preservation function will be insufficient, resulting in the food being cold when it reaches the consumer, which also affects the taste.

[0021] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the present invention are further described below in conjunction with the accompanying drawings and through specific implementation methods. It is understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for the convenience of description, only the parts related to the present invention are shown in the accompanying drawings, rather than all of them.

[0022] See also Figure 1 - Figure 5 , this embodiment provides a lunch box.

[0023] It comprises a box body 1, a box cover 2 and an upper cover 3.

[0024] The box cover 2 is covered on the box body 1 , and the two sides of the box cover 2 extend outward to form a fastening belt 21 , on which an adhesive tape 23 is arranged. The adhesive tape 23 is arranged at a position a distance above the end of the fastening belt 21 .

[0025] The box cover 2 is provided with a first vent hole 22 , the upper cover 3 is provided with a second vent hole 31 , the upper cover 3 is tightly covered on the box cover 2 , and a breathable heat-insulating material is filled between the upper cover 3 and the box cover 2 .

[0026] A plurality of first vent holes 22 are provided and evenly distributed on the box cover 2 .

[0027] A plurality of second vent holes 31 are provided and evenly distributed on the upper cover 3 .

[0028] The upper cover 3 and the box lid 2 are pressed together or glued together.

[0029] Preferably, the box body 1, the box cover 2 and the upper cover 3 are made of paper, which is easy to decompose and degrade, and is environmentally friendly and pollution-free. The breathable and heat-insulating material is a material with breathable and heat-insulating effects such as non-woven fabrics, cotton, non-woven fabrics, paper fibers, etc.

[0030] like Figure 2 As shown, food is contained in the box body 1, a plurality of first vents 22 are provided on the box cover 2, and second vents 31 are provided on the upper cover 3. The heat generated by the food in the box body 1 is dissipated through the first vents 22 and the second vents 31, so as to prevent the heat from not being dissipated and the generated water vapor from destroying the crisp taste of the food. At the same time, in order to prevent the heat from being dissipated too quickly and the heat preservation performance of the lunch box is reduced, the space between the box cover 2 and the upper cover 3 is filled with a breathable heat preservation material, so as to ensure the air permeability and the heat preservation effect.

[0031] like Figure 5 As shown, the presence of the fastening belt 21 makes the connection between the box cover 2 and the box body 1 more reliable, preventing the two from separating and falling off during transportation, thereby preventing food from leaking.

[0032] like Figure 5 As shown, the adhesive tape 23 is located a distance above the end of the fastening belt 21. After the fastening belt 21 is adhered to the box body 1, the end is slightly raised, which is convenient for the user to grab it to open it and use it easily.

[0033] like Figure 5 As shown, the fastening belt 21 has a fold that matches the edge of the box body 1. The fastening belt 21 is bent to form a hook shape to hook the edge of the box body 1. The lower end of the fastening belt 21 is bonded to the box body 1 through the adhesive tape 23. The function of the adhesive tape 23 is to maintain the shape of the hook and ensure that the box cover 2 and the box body 1 are tightly closed through the hook. This connection method makes the box cover 2 and the box body 1 more reliable.

[0034] The adhesive tape 23 is configured as a disposable adhesive tape, which can prevent the risk of the meal box being opened and eaten secretly during takeaway delivery, and ensure that the customer can check whether the meal box has been opened.

[0035] like Figure 6 As shown, the outer wall of the box body 1 is composed of an inner and outer layer, a cavity 12 is formed between the inner and outer layers, and the cavity 12 is filled with a breathable heat-insulating water-absorbing material. A vent hole 11 is provided on the outer wall of the box body 1, and the hot air inside the box body 1 can be discharged to the outside of the box body 1 through the vent hole 11. In order to prevent the heat preservation effect of the lunch box from decreasing due to too fast ventilation, a breathable heat-insulating water-absorbing material is provided to slow down the ventilation speed, and at the same time absorb the moisture in the hot air to maintain the taste and flavor of the food.

[0036] In the description of the present invention, it should be noted that the terms "up", "down", "left", "right", "clockwise" and "counterclockwise" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0037] The above embodiments are only to illustrate the basic principles and characteristics of the present invention. The present invention is not limited by the above embodiments. Without departing from the spirit and scope of the present invention, the present invention may be subject to various changes and modifications, which are within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
