Detailed Description
For a further understanding of the structure, features, and other objects of the utility model, reference should now be made in detail to the accompanying drawings of the preferred embodiments of the utility model, which are illustrated in the accompanying drawings and are for purposes of illustrating the concepts of the utility model and not for limiting the utility model.
As shown in fig. 1, fig. 1 is a schematic structural view of the pulp tray of the present utility model. The pulp tray 4 is made of pulp through compression molding and is formed by integrally forming, and comprises a square planar bottom 1, side walls 2 surrounding the bottom 1 and a cavity S with an opening at the top, wherein the cavity S can contain products. The pulp tray had a thickness of 0.6mm.
As shown in fig. 1, the side wall 2 is enclosed on the bottom 1 with four trapezoidal slopes. The connection part of the side wall 2 and the bottom 1 is in arc transition, and the connection part of the four surfaces of the side wall 2 is in arc transition. The side wall and the bottom are connected in a circular arc transitional manner, so that the edge smoothness of the tray is improved to prevent scratch phenomenon, and the cleaning is convenient. The angles between the four surfaces of the side wall 2 and the bottom 1 are 90-120 degrees. Referring to the cross-sectional view of the pulp tray shown in fig. 2, the cross-sections of the left and right surfaces of the side wall 2 are inclined surfaces in a stepped shape, and correspondingly, the cross-sections of the front and rear surfaces of the side wall 2 are also inclined surfaces in a similar stepped shape.
