Description

Technical Field

[0001] The utility model relates to a food container, in particular to a disposable lunch box. Background Art

[0002] In order to adapt to the fast-paced urban life, the contemporary catering industry has launched online ordering and meal delivery services. The commonly used packaging method is to use disposable packaging boxes to pack food. In order to facilitate the take-out of the packaging boxes, plastic bags are usually provided to store the packaging boxes, forming a bag-in-box method. However, the above packaging method requires the food and the packaging boxes to be packed in turn, resulting in a long packaging time, which is time-consuming and easy to consume manpower and material resources in the packaging process. In addition, during peak hours such as lunch and dinner, the staff puts the packaging box in the plastic bag and then ties it. Often due to the rush, the packaging box is not placed in the center of the plastic bag, which easily causes the deliveryman to lift the handle of the plastic bag. The packaging box will be tilted, the soup will flow out, and the entire meal box will be stained with soup, which is inconvenient to eat. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a disposable lunch box which is convenient for packing.

[0016] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0017] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.

[0018] Some embodiments of the present invention are described below in conjunction with the accompanying drawings.

[0019] Reference Figure 1-3A disposable lunch box for convenient packaging, comprising a packaging box body 1 with an open top, the disposable lunch box also comprising a plastic bag 2, the plastic bag 2 comprising a mounting portion 3, a first folding portion 4 and a second folding portion 5 from the inside to the outside, the mounting portion 3 having an open bottom, the upper end of the mounting portion 3 being connected to the first folding portion 4, the lower end of the first folding portion 4 being connected to the lower end of the second folding portion 5; the inner side of the mounting portion 3 is mounted on the outer side of the packaging box body 1; the mounting portion 3, the first folding portion 4 and the second folding portion 5 are connected to each other; The sides of the folded portion 4 and the second folded portion 5 are fitted together to form a "W" shape. A box cover 6 is installed on the top of the packing box body 1. When in use, put the food into the packing box body, cover the box cover, pull the second folded portion upward and tie it to form a closed package with an upper bag and a lower box. Compared with most of the current takeout packaging, the integrated setting of the packing box and the packaging bag can effectively shorten the packaging time of the fast food industry, save manpower and material resources for packaging, and allow the takeout economy with hot sales to achieve faster packaging efficiency.

[0020] The mounting portion 3 is mounted on the upper middle portion of the packaging box body 1 so that the entire center of the packaging box is located below the mounting portion 3 to avoid tilting of the packaging box body 1 due to an excessively high center of gravity, thereby increasing the risk of soup flowing out.

[0021] The mounting portion 3, the first folding portion 4 and the second folding portion 5 are integrally formed. During production, the packing box body 1 and the plastic bag 2 are produced independently of each other. The plastic bag 2 is put on the outside of the packing box body 1 through a subsequent assembly line (at this time, the side surfaces of the mounting portion 3, the first folding portion 4 and the second folding portion 5 in the plastic bag 2 abut against each other to form a "W" shape, such as Figure 1 As shown in A), the whole can be stacked according to a certain quantity and packed for storage (the production process of this product is not the focus of this application, such as how the subsequent assembly line puts the plastic bag 2 on the outside of the packing box body 1, and the corresponding equipment are not within the scope of this application).

[0022] A handle portion 9 is provided at the upper end of the second folding portion 5 to further improve the convenience of packaging and delivery.

[0023] The side wall of the packing box body 1 is an inclined surface that tilts outward from the bottom to the top, that is, the diameter of the packing box body 1 gradually increases from the bottom to the top, which can effectively ensure that the packing box body 1 will not completely pass through the mounting portion 3 and cause the packing box body 1 to fall.

[0024] A raised ring 7 protruding outward is provided at the upper end of the packing box body 1. The raised ring 7 and the side wall of the packing box body 1 form a step structure, which can further reduce the possibility of the mounting portion 3 completely passing through the packing box body 1. The upper end of the mounting portion 3 is abutted against the lower end of the raised ring 7, or the upper end of the mounting portion 3 is located below the raised ring 7.

[0025] A fixing portion 8 is extended outward from the top of the packing box body 1, and the box cover 6 is installed on the fixing portion 8. When the second folding portion 5 is pulled up, the mounting portion 3, the first folding portion 4 and the second folding portion 5 are changed from a "W" shape to a complete upward plastic bag wall, and the inner side of the plastic bag wall is abutted against the outer side of the fixing portion 8, so that the plastic bag wall below the fixing portion 8 is in an inclined state (such as Figure 2 , 3 ), the upper portion of the fixing portion 8 is in a vertical state (as shown in C in FIG. Figure 2 , 3 As shown in D in FIG. 1 , the two parts of the plastic bag wall form an obtuse angle structure.

[0026] In order to prevent the user's hands from being easily scratched, the existing packaging box has a sharp edge generally arranged below the fixing portion 8 (such as Figure 2 , 3 As shown in E in the figure), under this structure, the wall of the plastic bag will directly contact the flared edge, so that the plastic bag is easily scratched. Therefore, a gap is provided between the uppermost end of the mounting portion 3 and the uppermost end of the packaging box body 1 (i.e., the distance between the uppermost end of the mounting portion 3 and the lower part of the fixing portion 8), and a triangular structure is formed between the gap, the fixing portion 8 and the plastic bag (as shown in FIG. Figure 2 , 3 As shown in B in the figure), the larger the distance between the intervals is, the smaller the inclination angle of the plastic bag is, because the fixing portion 8 is fixed, that is, the larger the angle of the obtuse angle structure is, in theory, when the obtuse angle structure becomes a flat angle structure, that is, the wall of the plastic bag is completely out of contact with the fixing portion 8, at this time, the wall of the plastic bag will not exert a force on the fixing portion 8, and the wall of the plastic bag will not be scratched. Therefore, when the angle of the obtuse angle structure is larger, the force exerted by the wall of the plastic bag on the fixing portion 8 is smaller, and the possibility of the plastic bag being scratched will be greatly reduced.

[0027] When the side surfaces of the mounting portion 3, the first folding portion 4 and the second folding portion 5 are pressed against each other to form a "W" shape, the uppermost end of the second folding portion 5 is lower than the top surface of the packing box body 1, and the second folding portion 5 is folded and located below the fixing portion 8, so as to prevent food from being spilled on the second folding portion 5, i.e., on the plastic bag 2, when food is contained.
