Abstract

The invention discloses a folding method of a small-mouth and wide-bottom quadrate box, and relates to a manufacturing method of a paper utensil. The folding method comprises the following steps of: taking square paper, and enabling a square to exist in the middle of the square paper; enabling four corners of the square in the middle and four corresponding corners of the square paper to respectively have two-corner connecting line positive folding lines 1; making oblique line positive folding lines 2 from the four corners of the square in the middle towards two adjacent paper edges to intersect with the paper edges at intersection points 3; forming four congruent isosceles trapezoids on the surface of the paper; making corner bisector negative folding lines 4 at the two-corner connecting line positive folding lines 1 and the two oblique line positive folding lines 2; folding according to folding lines of the square paper, so that the initial shape of a box body is formed; folding according to parallel positive folding lines, so that folded parts is are in an inverted isosceles trapezoid shape; folding according to equidistant negative folding lines; and folding according to positive folding lines of a sharp corner part to fold towards the outer side of the box, so that the small-mouth and wide-bottom quadrate box is formed. The folding method is simple and easy; the shape is novel and peculiar; the small-mouth and wide-bottom quadrate box has practicability, and furthermore, is stout and durable; and the size proportion of a small mouth to a wide bottom can be randomly adjusted as required.

Description

The method for folding of square box of the wide end of a kind of osculum

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 side's carton is Fang Tizhuan straight up and down, homalographic at the bottom of box mouth and the box, the rare wide end of osculum; The carton at the wide end of osculum that box mouth height is straggly is then rare especially.

Summary of the invention

Mostly be straight up and down Fang Tizhuan in order to overcome existing side's carton, homalographic at the bottom of box mouth and the box, the rare wide end of osculum; The carton at the wide end of osculum that box mouth height is straggly is rare deficiency especially then, the invention provides the method for folding of square box of the wide end of a kind of osculum.

The technical solution adopted for the present invention to solve the technical problems is: get square of paper, at the paper middle part one middle part square is arranged; The foursquare four edges trimming corresponding with square of paper, middle part is parallel, and distance is equal, and the foursquare four edges in middle part is positive broken line; There are respectively two jiaos of positive broken lines 1 of line at four angles corresponding with square of paper, foursquare four angles, middle part; Article four, the positive broken line of two jiaos of lines 1 is isometric; Do the positive broken line 2 of oblique line by two contiguous trimmings of foursquare four angles, middle part, to intersect at the positive broken line of 3, eight oblique lines of intersection point 2 isometric with the trimming; Paper forms the isosceles trapezoid of four congruences, and foursquare limit, middle part is going to the bottom of isosceles trapezoid, and the line segment on the trimming corresponding with foursquare limit, middle part between two intersection points 3 is upper base, and the positive broken line 2 of two oblique lines that links to each other with the upper base two ends is waists; It is isometric to do respectively 4, eight angular bisector fold lines 4 of angular bisector fold line at the angle of two jiaos of positive broken lines 1 of line and two positive broken lines 2 of oblique line;

The positive broken line 1 of two jiaos of lines, the positive broken line 2 of oblique line and angular bisector fold line 4 fold lines according to described square of paper are folding, foursquare four edges is corresponding just rolls at the middle part, the preliminary shape of square box of the wide end of an osculum, the box side is the isosceles trapezoid shape, there is the wedge angle of a projection inboard, box angle; On the isosceles trapezoid of box lateral surface, be as the criterion with the position of intersection point 3 and do one and be parallel to the parallel positive broken line 5 that upper base is gone to the bottom;

Fold according to described parallel positive broken line 5, the above part of the parallel positive broken line of box side isosceles trapezoid is folded to the below, and folded part is the shape of falling the isosceles trapezoid; Fall isosceles trapezoid do one with the upper base and parallel and equidistant equidistant parallel fold line 6 of going to the bottom of isosceles trapezoid;

Fold according to described equidistant parallel fold line 6, the equidistant parallel fold line 6 following part reflexeds of isosceles trapezoid; Partly do a positive broken line 7 of wedge angle part at wedge angle, the two ends of the positive broken line 7 of wedge angle part are intersection point 3; During wedge angle part generate plane, the positive broken line 7 of wedge angle part is straight line;

Folding according to the positive broken line of described wedge angle part 7, the positive broken line of wedge angle part 7 or more part be folded to outside the box, square box of the wide end of osculum.

The invention has the beneficial effects as follows that the method for folding of square box of the wide end of osculum is simply easy; Modern design, peculiar; The tool practicality, and durable; The size at the wide end of osculum can be adjusted arbitrarily as required.
