Abstract

The invention discloses a method for folding a parallel twin-box, relating to a method for making paper containers. The method comprises the following steps of: fetching a piece of rectangular paper with the length-width ratio of 5:2; longitudinally making two folding lines to divide the paper into three rectangles, wherein the two longitudinal rectangles at the left and right ends are congruent; folding the left and right rectangles, and folding to obtain eight congruent right-angle isosceles small triangles at the eight angles of the two rectangles to form four isosceles trapezoids in left and right groups; folding outwards the two isosceles trapezoids in the middle to form two congruent isosceles trapezoids, wherein the square between the two isosceles trapezoids is divided into two congruent longitudinal rectangles on the left and right; making eight congruent right-angle isosceles small triangles on the eight angles of the two rectangles, and folding along the folding lines to form a basic shape of the twin-box with an interlayer; and inserting the four triangles on the outer side surface of the box into an adjacent oblique interlayer on the outer side surface of the box respectively so as to form the parallel twin-box. The parallel twin-box separates the space of the box body, increases the functions of the box, is simple to make, low in cost and firm and durable, and looks square and beautiful.

Description

The method for folding of parallel twin-box

Technical field

The present invention relates to a kind of preparation method of vessel, especially a kind of preparation method of paper utensil.

Background technology

At present, mostly known paper utensil is single, rare disjunctor; Large bonding the forming of multiplex single paper utensil of paper utensil of disjunctor arranged, make and dislike complicated, operation is more.

Summary of the invention

Mostly be single in order to overcome existing paper utensil, rare disjunctor; Large bonding the forming of multiplex single paper utensil of paper utensil of disjunctor arranged, make and dislike complicated, the deficiency that operation is more the invention provides a kind of method for folding of parallel twin-box.

The technical solution adopted for the present invention to solve the technical problems is: getting grow crosswise vertical wide be 5: 2 rectangular paper, vertically do the positive broken line fold line of twice, paper is divided into three rectangles, two the first vertical rectangles in two ends, the left and right sides are congruent, the lengthwise horizontal stroke is short, the length ratio is 2: 1; Grow crosswise and indulge short rectangle in the middle part, the length ratio is 3: 2;

Two ends, the left and right sides first vertical rectangle is folding to the middle part, forms second vertical rectangle of three congruences; The oblique positive broken line in eight roads is made at eight angles of two second vertical rectangles at two ends, forms eight little triangles of congruence the first right angle isosceles, and summit, eight little leg-of-mutton right angles of the first right angle isosceles is the summit at eight angles of two second vertical rectangles, two ends; The little leg-of-mutton waist length of the first right angle isosceles is 1/2 of second vertical rectangle broadside;

The little triangle of the first right angle isosceles at four angles, two ends, the left and right sides is double-deck positive folding, the little triangular single-layer of four the first right angle isosceles adjacent with middle part second vertical rectangle is positive folding, two adjacent little leg-of-mutton waists of the first right angle isosceles vertically join, the little leg-of-mutton waist of the first right angle isosceles that twice were vertically joined about with dashed lines connected is made vertically positive broken line; About formation two groups take twice vertically positive broken line as the isosceles trapezoid of four congruences of going to the bottom, every group of two isosceles trapezoid totally one go to the bottom;

Two isosceles trapezoids with the middle part, folding to the left and right by the center according to the vertically positive broken line of twice, part after folding forms the isosceles trapezoid of two congruences, the upper base of two isosceles trapezoids is gone to the bottom and two waists are the interlayer opening, make four trapezoidal fold lines at two end points of upper base on two interlayer upper stratas high, make corresponding four positive broken lines in the interlayer lower floor that is covered by the interlayer upper strata high; In the square between two isosceles trapezoids, vertically make fold line one, two congruence the 3rd vertical rectangles about square is divided into; Up and down two 1/4 line segments of longitudinal folding line are the fold line line segment, and middle part 1/2 line segment is positive broken line line segment; Make the oblique positive broken line in eight roads at eight angles of two the 3rd vertical rectangles, form eight little triangles of congruence the second right angle isosceles, summit, eight little leg-of-mutton right angles of the second right angle isosceles i.e. the summit at eight angles of two the 3rd vertical rectangles; The little leg-of-mutton waist length of the second right angle isosceles is 1/2 of the 3rd vertical rectangle broadside; Two the 3rd vertical rectangles little leg-of-mutton phase contact of two the second right angle isosceles of broadside up and down about connecting respectively with vertical fold line;

After putting in place according to fold line is folding, be formed with two box basic configurations of interlayer, at two box lateral surfaces that link to each other with interlayer, respectively have two with the box lateral surface in the middle part of vertical triangles that link to each other; The oblique line of two box lateral surfaces is the interlayer opening;

Four triangles of box lateral surface are inserted respectively the box lateral surface with it in the adjacent oblique line interlayer, parallel twin-box.

The invention has the beneficial effects as follows, isolated box space, increased the function of box; Make simple, with low cost; Well-pressed attractive in appearance, sturdy and durable.
