Description

Technical Field

[0001] The utility model relates to the technical field of food packaging, in particular to a curled edge food tray. Background Art

[0002] Food trays are a common food tray in the catering industry or at home. Due to food hygiene requirements, general food trays are disposable products made of plastic. These products have low rigidity, are easily damaged, and have limited load-bearing capacity. Therefore, food trays are generally folded at the edges to enhance the structural strength of the entire edge.

[0003] For example, the Chinese utility model patent with patent announcement number CN214058198U discloses a rolled-edge tray, the outer edge of which is bent downward to form a reinforcing plate. The angle at which the reinforcing plate is bent downward is a bending angle α, and the range of the bending angle α is: 90°≤α≤180°. However, it should be noted that in many usage scenarios, fruits and vegetables packed on food trays are packaged with plastic wrap. When the bending angle is small, the sharp edge contacts the plastic wrap because it is not completely bent, which can easily cause the plastic wrap to be scratched, thereby affecting the preservation effect of the food and posing a risk of scratching the hands. When the angle is too large, such as α=180°, although there is no problem of the plastic wrap being scratched, the folded edge is in close contact with the top reinforcing plate, making it difficult to separate multiple trays when they are stacked due to their small thickness. Based on this, we provide a rolled-edge food tray. Utility Model Content

[0004] The utility model aims to provide a food tray with a rolled edge, so as to solve the problems of the existing food tray having a risk of scratching the cling film or human hands due to the rolled edge, low rolled edge strength and inconvenience in separation.

[0005] The utility model can be implemented through the following technical solution: a rolled-edge food tray, comprising a food tray body, the food tray body comprising four side walls and four transition fillets alternately connected and enclosed and arranged around a bearing area at the bottom to form a accommodating cavity, horizontal edges are set at the top edges of the four side walls and the four transition fillets, and a rolled edge with a triangular, quadrilateral, circular or elliptical cross-section is set on the outer side of the edge, and the height range of the rolled edge is set to 1mm to 6mm.

[0006] A further technical improvement of the present invention is that a plurality of supporting ribs protruding into the cavity are provided in the accommodating cavity, and the supporting ribs extend vertically from the side wall to the bearing area.

[0007] A further technical improvement of the present invention is that the curled edge with a quadrilateral cross section includes an arc-shaped transition section smoothly connected to one side of the edge, the transition section is semicircular, and a horizontal folded edge is provided on the side of the transition section away from the edge.

[0008] A further technical improvement of the present invention is that the rolled edge with an elliptical cross section includes an arc-shaped transition section smoothly connected to one side of the edge, and the end of the transition section away from the edge is sequentially provided with a vertical folded edge and an arc-shaped inward rolled folded edge.

[0009] A further technical improvement of the present invention is that the curled edge with a circular cross section includes an inner curled edge directly connected to the outer edge of the edge.

[0010] A further technical improvement of the present invention is that the rolled edge with a triangular cross-section includes an arc-shaped transition section connected to one side of the edge, and the end of the transition section away from the edge is successively provided with an inner folding edge 1 and an inner folding edge 2, and the turning point of the inner folding edge 1 and the inner folding edge 2 is set as a rounded corner.

[0011] A further technical improvement of the present invention is that the maximum height of the vertical fold is set to 5 mm.

[0027] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0028] See also Figure 1-2 As shown, a rolled-edge food tray includes a food tray body 1, which includes a load-bearing area 2 at the bottom, four side walls 3, and four transition fillets 5. The four side walls 3 and the four transition fillets 5 are alternately connected and enclosed around the load-bearing area 2, thereby forming a receiving cavity. A plurality of support ribs 4 protruding into the cavity are provided in the receiving cavity. The support ribs 4 extend vertically from the side walls 3 into the load-bearing area 2. The support ribs 4 also form intermittent grooves while protruding inwardly, thereby preventing the bottom of the entire food tray body 1 from contacting the table surface and causing overall scratches. At the same time, the support ribs 4 can also provide a certain support for fruits and vegetables, thereby isolating them from direct hard contact with the table surface and providing a buffering and protective effect.

[0029] Horizontal edges 6 are provided at the top edge positions of the four side walls 3 and the four transition fillets 5 . The outer ends of the edges 6 are provided with curling edges 7 . The height of the curling edges 7 is set to 1 mm to 6 mm.

[0030] Example 1

[0031] like Figure 3 As shown, the contact position between the curling edge 7 and the edge 6 is set as an arc-shaped transition section 701, the arc of the transition section 701 is semicircular, and the end of the transition section 701 away from the edge 6 is set as a horizontal fold 703; the setting of the transition section 701 avoids the risk of easy scratching of the plastic wrap or hands; Figure 4 As shown, the presence of the transition section 701 and the horizontal fold 703 allows a certain gap to be formed when the two food tray bodies 1 are stacked, making them easy to separate. The horizontal fold 703 is supported on the top of the edge 6. However, this method has low strength because the horizontal fold 703 cannot be completely rolled in. It is also easy to scratch fingers when carrying.

[0032] Example 2

[0033] like Figure 5-6 As shown, compared with the first embodiment, the curled edge 7 on the outer side of the edge 6 includes an arc-shaped transition section 701, which is similar to a rounded corner transition form. The end of the transition section 701 away from the edge 6 is sequentially provided with a vertical folded edge 702 and an arc-shaped inward-rolled folded edge 704, and the end of the inward-rolled folded edge 704 is close to the bottom of the edge 6;

[0034] The maximum vertical fold 702 in this embodiment is set to 5mm. Due to the presence of the inward fold 704, the strength of this structure is greatly enhanced compared to the first embodiment, and there is no sharp side edge that may cause scratches to the plastic wrap or people's hands.

[0035] When a plurality of food tray bodies 1 are stacked, the stacking distance between two adjacent food tray bodies 1 is large, which makes it easy for customers to separate them and facilitate use.

[0036] Example 3

[0037] like Figure 7-8 As shown, based on the second embodiment, the arc-shaped transition section 701 and the vertical fold 702 are ignored, and an inner fold 704 is directly provided on the outer side of the edge 6. This ensures strength and safety while reducing the height difference of the entire fold 7, making the stacking distance smaller, so that more food pallet products can be transported in the same transportation space, reducing transportation costs, and also reducing product packaging consumables.

[0038] Example 4

[0039] like Figure 9-10As shown, the curling edge 7 of this embodiment includes an arc-shaped transition section 701 smoothly connected to the outer side of the edge 6. The end of the transition section 701 away from the edge 6 is sequentially provided with an inner fold edge 1 705 and an inner fold edge 2 706. The turning point between the inner fold edge 1 705 and the inner fold edge 2 706 is set as a rounded corner. The end of the inner fold edge 2 706 faces the bottom of the edge 6, forming a triangular structure.

[0040] Furthermore, let the angle between the inner fold edge 1 705 and the plane where the edge 6 is located be α, and the angle between the inner fold edge 1 705 and the plane where the inner fold edge 2 706 is located be β, the range of the angle α is 20° to 60°, and the range of the angle β is 60° to 120°;

[0041] The stacking distance of the curling edge 7 of this triangular structure is short, which can reduce the packaging and transportation costs of the product, and the triangle has good strength and is not easy to deform.

[0042] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
