DETAILED DESCRIPTION

[0023] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0024] Example 1

[0025] like Figure 1-Figure 3 As shown, this embodiment discloses a foldable disposable dinner plate, which is formed by folding a flat sheet. The sheet is an edible-grade paper sheet, specifically bagasse paper. The disposable dinner plate is a completely flat sheet before being formed, which can effectively save storage space.

[0026] The 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 sheet, the flange areas 20 are respectively located at the four side edges of the 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 sheet.

[0027] Each of the folding corner areas 30 is provided with an outward fold line 31 and an outward fold line 32, and both the outward fold line 31 and the outward fold line 32 extend outward from the inner end corner of the folding corner area 30 to the outer edge, and the outward fold line 31 coincides with the diagonal line of the folding corner area 30, and the angle between the outward fold line 31 and the outward fold line 32 is not greater than 45 degrees; the folding corner area 30 can be outwardly folded along the outward fold line 31 to form a double-layer outward folding wing 37, and the four flange areas 20 are flipped up along the corresponding partition fold lines to form an upper flip edge when the folding corner area 30 is folded, and together with the supporting area 10 define a cavity for holding food, and the double-layer outward folding wing 37 is located outside the cavity, and is folded along the outward fold line to fit with the corresponding flange area 20 to reinforce the dinner plate.

[0028] There are four partition 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 above-mentioned structure of 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, so that the cavity of the formed dinner plate is larger.

[0029] The extrapolated fold line 31 divides the folded area 30 into two symmetrical triangular half-areas, namely a first half-area 33 and a second half-area 332. The outer fold line 32 deviates from the corresponding longitudinal fold section 422 and is located within the first half-area 33. In this embodiment, the angle between the outer fold line 32 and the extrapolated fold line 31 is 30 degrees. The inner and outer layers of the double-layer outer flap 37 are located in the two halves, respectively, and are mirror-symmetrical. An inner triangle 331 is formed between the outer fold line 32 and the extrapolated fold line 31, and this inner triangle 331 constitutes the inner layer of the double-layer outer flap 37. The deviation of the outer fold line 32 from the corresponding longitudinal fold angle enables the final formed dinner plate to have an outward flared opening, which is convenient for holding food.

[0030] The corner area 30 also has an inward fold line 35. This inward fold line 35 has two sections, symmetrically arranged on either side of the outward fold line 31, and defines two inward fold edges 36. When the double-layered outer flap 37 is formed, the two inward fold lines 35 overlap, and the two inward fold edges 36 overlap and protrude above the upper edge of the corresponding flange area 20. The two inward fold edges 36 can be inwardly turned along the inward fold line 35 into the cavity and fit into the corresponding flange area 20. The provision of the inward fold edges 36 can reinforce the corners of the dinner plate and further improve the structural stability of the formed dinner plate.

[0031] The adhesive sheet, a double-sided tape 50, is fixed to the back of the inner triangle 331 and can be used to bond the inner triangle 331 to the corresponding flange 20, i.e., the outer wall of the upper flange of the formed plate. The double-sided tape 50 is convenient, low-cost, and stable. The partition fold lines, outward fold line 31, outward fold line 32, and inward fold line 35 are all prefabricated on the sheet and stamped to facilitate the formation of the plate.

[0032] Example 2

[0033] See also Figure 4 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 inner folding edge 36 located on the inner side, and can adhere and fix the inner folding edge 36 to the corresponding flange area 20, that is, the inner wall of the upper flange of the formed plate.

[0034] Example 3

[0035] See also Figure 5 、 Figure 6 This embodiment discloses a foldable disposable dinner plate, which is formed by folding a flat sheet material, wherein the sheet material is bagasse paper. The disposable dinner plate is a completely flat sheet material before being formed, which can effectively save storage space.

[0036] The 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 sheet, the flange areas 20 are respectively located at the four side edges of the 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 sheet.

[0037] Each of the folding corner areas 30 is provided with an outward fold line 31 and an outward fold line 32, and both the outward fold line 31 and the outward fold line 32 extend outward from the inner end corner of the folding corner area 30 to the outer edge, and the outward fold line 31 coincides with the diagonal line of the folding corner area 30, and the angle between the outward fold line 31 and the outward fold line 32 is not greater than 45 degrees; the folding corner area 30 can be outwardly folded along the outward fold line 31 to form a double-layer outward folding wing 37, and the four flange areas 20 are flipped up along the corresponding partition fold lines to form an upper flip edge when the folding corner area 30 is folded, and together with the supporting area 10 define a cavity for holding food, and the double-layer outward folding wing 37 is located outside the cavity and fits with the corresponding flange area 20 to reinforce the dinner plate.

[0038] There are four partition 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 above-mentioned structure of 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, so that the cavity of the formed dinner plate is larger.

[0039] The extrapolated fold line 31 divides the folded corner area 30 into two symmetrical triangular half areas, namely the first half area 33 and the second half area 332. The outer fold line 32 coincides with the corresponding longitudinal folded corner section 422. The first half area 33 constitutes the inner layer of the double-layer outer wing 37, and the second half area 332 constitutes the outer layer of the double-layer outer wing 37. The adhesive sheet is a double-sided tape 50, which is fixed on the reverse side of the first half area 33 and can adhere and fix the double-layer outer wing 37 to the outer wall of the corresponding folded area. The formed dinner plate has a regular rectangular structure, which is simpler and more beautiful. The partition fold lines, extrapolated fold lines 31, and outer fold lines 32 are all prefabricated on the sheet and stamped to facilitate the formation of the dinner plate.
