DETAILED DESCRIPTION

[0019] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0020] Example 1

[0021] like Figure 1 、 Figure 2 As shown, this embodiment discloses a food tray, which is formed by folding a paper sheet. The material of the paper sheet is bagasse paper. The food tray is a completely flat sheet before being formed, which can effectively save storage space.

[0022] The paper sheet is divided into multiple functional areas by partition fold lines, and the functional areas include a supporting area 10, four flange areas 20 and four corner areas 30. The supporting area 10 is located in the middle of the paper sheet, the flange areas 20 are respectively located at the four side edges of the paper sheet and are respectively aligned with the four side edges of the supporting area 10, and the corner areas 30 are respectively located at the four end corners of the paper sheet.

[0023] Each of the folding corner areas 30 is provided with an inner push fold line 31 and an inner overlap fold line 32, and the inner push fold line 31 and the inner overlap fold line 32 both extend outward from the inner end angle of the folding corner area 30 to its outer edge, and the inner push fold line 31 deviates from the diagonal line of the folding corner area 30, and the inner overlap fold line 32 coincides with the tail end of the corresponding partition fold line, and the angle between the inner overlap fold line 32 and the inner push fold line 31 is less than 45 degrees. Specifically, in this embodiment, the angle between the inner overlap fold line 32 and the inner push fold line 31 is 30 degrees; Area 30 can be folded inward along an inward fold line 31 to form a double-layer inner flap 37. When the corner area 30 is folded, the four flap areas 20 are automatically flipped upward along the corresponding partition fold lines to form an upper flap, and together with the support area 10, define a food storage cavity. The double-layer inner flap 37 is located within the cavity and can be folded inward along the inward fold line 32 to overlap the corresponding flap area 20, that is, to overlap the upper flap of the formed food tray. The double-layer inner flap 37 can enhance the structural strength of the food tray. The inward fold line 31 is set off the diagonal line of the corner area 30, which can make the final food tray have an outward flared opening, making it more convenient to hold food.

[0024] There are four partitioning fold lines arranged in a crisscross pattern, including two mutually parallel transverse fold lines 41 and two mutually parallel longitudinal fold lines 42. The support area 10 is rectangular, and the two transverse fold lines 41 each include a transverse forming section 411 for defining the transverse side edges of the support area 10, and transverse corner sections 412 located at both ends of the transverse forming section 411. The two longitudinal fold lines 42 each include a longitudinal forming section 421 for defining the longitudinal side edges of the support area 10, and longitudinal corner sections 422 located at both ends of the longitudinal forming section 421. The four flange areas 20 are all rectangular and mirror-symmetrical with each other; the four corner areas 30 are all square and mirror-symmetrical with each other. The use of the above-mentioned structure in each functional area can make the structure of the entire dinner plate more regular and stable, and can fully utilize the various areas of the sheet material, making the formed food tray larger in volume.

[0025] The inner fold line 32 coincides with the corresponding longitudinal fold section 422, and the inward fold line 31 divides the fold area 30 into a triangular area 33 and a trapezoidal area 34. The triangular area 33 constitutes the inner layer of the double-layer inner fold wing 37; the trapezoidal area 34 is provided with an overlapping area that can overlap with the triangular area 33, and the overlapping area constitutes the outer layer of the double-layer inner fold wing 37, and the overlapping area and the triangular area 33 are symmetrically distributed on both sides of the inward fold line 31. After the fold area 30 is pushed inward and folded along the inward fold line 31, the triangular area 33 overlaps with the overlapping area to form a double-layer inner fold wing 37. The trapezoidal region 34 also has an outward-turning fold line 35, which is located near the outer corner of the corner region 30 and defines an outward-turning edge 36 with the two perpendicular side edges of the corner region 30. The outward-turning edge 36 is triangular and can be turned outward along the outward-turning fold line 35 to the outside of the container cavity, conforming to the corresponding flange region 20. The provision of the outward-turning edge 36 can reinforce the food tray and further improve the structural stability of the formed food tray. The partition fold lines, inward-pushing fold line 31, inner-lapping fold line 32, and outward-turning fold line 35 are all prefabricated on a paper sheet and stamped to make the food tray more uniform and regular in structure and facilitate its formation.

[0026] The adhesive sheet is a double-sided tape 50, which is fixed on the front of the triangular area 33 and can adhere the triangular area 33 to the inner wall of the corresponding flange area 20, that is, the inner wall of the upper flange of the food tray after molding. The double-sided tape 50 is used for bonding, is low in cost, and is stable.

[0027] Example 2

[0028] See also Figure 2 The difference between this embodiment and embodiment 1 is that the double-sided tape 50 is set at a different position. In this embodiment, the double-sided tape 50 is fixed on the back side of the outer folding edge 36 and can adhere and fix the outer folding edge 36 to the outer wall of the corresponding flange area 20, that is, the inner wall of the upper flange of the food tray after molding.
