Problems solved by technology

[0002] The bottom tray of the cake box is basically made of plastic and paper. Due to the consideration of its manufacturing cost, the strength of the tray made of plastic is poor, which is not conducive to transportation and carrying; the tray made of paper is generally made by hand, with low production efficiency and poor appearance. Rough, easy to introduce bacteria during production, handmade round or oval trays can also form a raised platform, but the platform should be made of two cardboards, one of which is used to form the platform countertop and the other is used to form the platform side walls, so that the bending strength is lower on the outside or bottom edge of the platform
There are gaps at the connection between the countertop and the side wall, and water or oil can easily penetrate into the cardboard through the gaps, causing local discoloration of the cardboard, and in extreme cases, bacteria may breed and accelerate food deterioration

Embodiment Construction

[0021] figure 1 A form of the upper cardboard 1 is shown, with a raised platform 2 in the middle, and creases 5 on the side walls 3 of the platform 2 and the bottom edge 4 of the upper cardboard 1 . The production of the upper cardboard 1 is to stamp the creases 5 on the periphery of the flat cardboard through the indentation die, and punch the raised platform 2 in the concave-convex die, wherein the peripheral part with the creases 5 forms the side wall 3 of the platform and the bottom edge of the upper cardboard 4. The creases 5 are preferably evenly distributed, forming a radial shape with the center of the above cardboard as the axis, so that the side walls 3 and the bottom edge 4 are evenly folded. Before making the cardboard, the paper surface of the flat cardboard can be waterproofed, such as composite plastic film, waterproof coating or polishing.

Abstract

The invention relates to the tray of the cake-box bottom and its facture and equipment. Use impressing mould to punch the radial strip folding lines on the outside of the paper board, then punch the paper board in concavo-convex mould to form the convex platform in the center of the paper board, the outside strip folding lines form the side wall and the base lines of the platform, stick the base lines to the lower base plate to form the tray of the box bottom.

Description

technical field [0001] The present invention relates to a package or container and its manufacturing method and equipment, more specifically to a cake box bottom tray made of cardboard and its manufacturing method and equipment.
