Method for folding triangular box with overlying box bottom

Abstract

The invention discloses a method for folding a triangular box with an overlying box bottom and relates to a method for manufacturing paper containers. Paper in the shape of an equilateral triangle is taken, and folding lines such as oblique line positive fold lines, a two-point reverse fold line and a three-point positive fold line are made; three angles are folded according to the three oblique line positive fold lines; a first large angle portion is folded according to the three-point positive fold line; folding is performed according to a coincided four-point positive fold line of the first large angle portion, a coincided vertical line positive fold line, a middle edge reverse fold line adjacent to the coincided vertical line positive fold line, a four-point positive fold line of a second large angle portion adjacent to the middle edge reverse fold line and a vertical line positive fold line; the portion above a first coincided three-point positive fold line is folded according to the first coincided three-point positive fold line of the second large angle portion, and one box angle is formed; the other two box angles are folded in the same way; the triangular box with the overlying box bottom can be formed by adjusting a third large angle portion, suspended above the first large angle portion, of the box bottom to a position below the first large angle portion. The design is simple and clear, manufacturing is easy, due to the overlying state of an inner box bottom, the box bottom can not deform, and the triangular box with the overlying box bottom is stiff, smooth and firm.

Description

technical field [0001] The invention relates to a method for making a vessel, in particular to a method for making a paper vessel. Background technique [0002] At present, the adhesion between the inner and outer layers of the side of the known triangular box is not good enough, and the inner layer is easily detached from the outer layer and unfolded into the box, causing the box body to deform and not firm enough. Contents of the invention [0003] In order to overcome the problem that the adhesion between the inner and outer layers on the side of the existing triangular box is not good enough, the inner layer is easily separated from the outer layer and unfolded into the box, causing the box body to deform and not firm enough, the present invention provides a laminated The folding method of the triangular box with the bottom of the press box. [0004] The technical scheme that the present invention solves its technical problem adopts is: get equilateral triangle paper,...
