Abstract

A variable triangular box with a wide opening relates to a paper utensil. The bottom of the variable triangular box is an equilateral triangle, each lateral side of the variable triangular box is pentagon which consists of an equilateral triangle and two congruent right angled isosceles triangles, one edge of the equilateral triangle is a bottom edge of the bottom of the variable triangle box, the other two edges of the equilateral triangle are bevel edges of the two congruent right angled isosceles triangles, the angle of the right angle isosceles triangle adjacent to the bottom angle of the equilateral triangle is 60 degrees. The variable triangular box with the wide opening is improved on the basis of a conventional triangular box and has practicality and enjoyment.

Description

Variant wide-mouth triangle box

Technical field

The utility model relates to a kind of vessel, especially a kind of paper utensil.

Background technology

At present, in the known paper utensil, the triangle box is more rare, and is different from common triangle box, and the triangle box that on body, changes is more rare.

Summary of the invention

In order to overcome in the existing paper utensil, the triangle box is more rare, and is different from common triangle box, the more rare deficiency of triangle box that on body, changes, and the utility model provides a kind of variant wide-mouth triangle box.

The utility model solves the technical scheme that its technical matters adopted: at the bottom of the box of variant wide-mouth triangle box is equilateral triangle; The box side is a pentagon; Box outside pentagon is made up of the right angled isosceles triangle of an equilateral triangle and two congruences; A limit of equilateral triangle is base at the bottom of the box; Other two limits of equicrural triangle are respectively the hypotenuse of the right angled isosceles triangle of two congruences; The angle of the right angled isosceles triangle adjacent with equilateral triangle box base angle is 60 degree.

The beneficial effect of the utility model is that variant wide-mouth triangle box is innovated on the basis of traditional triangle box, existing practicality, tool sight again.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Fig. 1 is the equilateral triangle paper plane figure that is decorated with fold line;

Fig. 2 becomes the box-like block diagram of basic triangle according to the folding back of Fig. 1 fold line;

Fig. 3 is the block diagram that the outer triangular portions of Fig. 2 box body is folded to the box body lateral surface;

Fig. 4 is a variant wide-mouth triangle box block diagram;

Fig. 5 is a variant wide-mouth triangle box body lateral surface planar view.

The specific embodiment

The method for folding of variant wide-mouth triangle box is, gets equilateral triangle paper, makes fold line; Dotted line is the positive broken line of positive doubling, and solid line adds circle and is the reflexed line of reverse side doubling; The middle part of equilateral triangle is a little equilateral triangle; Line between the corresponding angles of equilateral triangle and little equilateral triangle is the diagonal line of two acute angles of rhombus; There are three intersection points on every limit of fold line and equilateral triangle, and every limit is divided into four congruent line segments; The mid point on every limit is drawn two positive broken lines, and the angle on two positive broken lines and trimming is 30 degree; Like Fig. 1;

Folding according to the rhombus acute angle diagonal line of Fig. 1, fundamental triangle box-like, box body has the triangle that links to each other with box body outward; Like Fig. 2;

Folding according to the outer leg-of-mutton positive broken line of the box body of Fig. 2, be affixed to box body; Like Fig. 3;

Folding according to two positive broken lines of Fig. 3, variant wide-mouth triangle box; Like Fig. 4; Dotted portion is the perspective in the box outside;

Variant wide-mouth triangle box box outside form is like Fig. 5.

At the bottom of the box of variant wide-mouth triangle box is equilateral triangle; The box side is a pentagon; Box outside pentagon is made up of the right angled isosceles triangle of an equilateral triangle and two congruences; A limit of equilateral triangle is base at the bottom of the box; Other two limits of equicrural triangle are respectively the hypotenuse of the right angled isosceles triangle of two congruences; The angle of the right angled isosceles triangle adjacent with equilateral triangle box base angle is 60 degree; Like Fig. 5.

Claims

1. variant wide-mouth triangle box, it is characterized in that: at the bottom of the box of variant wide-mouth triangle box is equilateral triangle; The box side is a pentagon; Box outside pentagon is made up of the right angled isosceles triangle of an equilateral triangle and two congruences; A limit of equilateral triangle is base at the bottom of the box; Other two limits of equicrural triangle are respectively the hypotenuse of the right angled isosceles triangle of two congruences; The angle of the right angled isosceles triangle adjacent with equilateral triangle box base angle is 60 degree.
