CN2679045Y - Packing case - Google Patents

Abstract

The utility model relates to a packing case, comprising a sheet material. The sheet material is folded into a cube, and the sheet material respectively projects and extends upwards and downwards to form the upper cover and the bottom board of a case body. A connecting position between the bottom board and a lateral surface is provided with a U-shaped opening, and the U-shaped opening is faced to the lateral surface without folding edge. After a bottom surface is folded inwards and closed, the U-shaped opening is connected with the lateral surface as an entity for becoming the extended supporting part of the lateral surface and separating from the bottom surface. The packing case has the characteristics of simple use, low cost and convenient assemblage; the stability of placing the packing case is greatly enhanced, and the packing case is suitable for objects with high center of gravity and other goods with various geometric forms.

Description

A kind of packing box

Technical field

The utility model relates to a kind of cube packing box, particularly cosmetics, medicine, food cube packing box.

Background technology

The cube packing box is the external packing that a lot of commodity adopt.Along with the fast development of cosmetics industry, medicine company, food industry, take up product bottle, jar also form is various day by day.When bearing special external form commodity such as the higher bottle of imitative conical, imitative oval, arc or some centers of gravity, jar, common cube side adorns box and is difficult to satisfy its stationarity requirement, instability, easily topples over.

Technology contents

The utility model purpose is that design is a kind of simple in structure, both can strengthen conventional bottle, jar bear stability, can take up the reinforcement support type cube packing box of the higher or complicated three-dimensional shape article of center of gravity again.

The utility model purpose can be achieved through the following technical solutions.

A kind of packing box, form by sheet material, sheet material is amounted to into a cube, and sheet material upwards has outstanding loam cake and the base plate that constitutes box body that extend downwards respectively, there is " U " type opening base plate and junction, side, and " U " type opening part is amounted to rib to side and nothing, in the bottom surface after the invagination closure, " U " type and side are connected as a single entity becomes the support section that stretches out of side, and separates with the bottom surface.

Without between the bottom surface of bonding, the packing box lithographic plate amounted to and the lateral support face that is connected one shallow " U " type opening is being arranged, packing box is bonding, amount to shaping after, " U " shape opening becomes a support rib of strengthening firm effect between bottom and the lateral support face that is connected, with bearing surface of the common formation of other basal edges of side of the inside folding section of base plate, make whole packing box more stable.

The beneficial effects of the utility model are:

1, low cost;

2, production, easy to process;

3, has the effect of strengthening firm effect

Description of drawings

Fig. 1 is a lithographic plate scheme drawing of the present utility model.

Fig. 2 is a three-dimensional effect diagram of the present utility model.

Wherein, 1 is the side, and 2 is the bottom surface, and 3 is " U " type opening, and 4 is sheet material.

Specific implementation method

Below in conjunction with accompanying drawing, the utility model is further described:

Packing box, form by sheet material 4, sheet material is amounted to into a cube, and the side 1 of sheet material has the outstanding base plate 2 that constitutes box body that extends downwards, base plate 2 has " U " type opening 3 with the junction, side, and " U " type opening part is amounted to rib to side and nothing, in the bottom surface after the invagination closure, " U " type and side are connected as a single entity becomes the support section that stretches out of side, and separates with the bottom surface.

Packing box, at the opening that has between bottom surface and the side about a width 1mm, opening accounts for bottom surface side 3/5ths width, the opening mid point overlaps with the base mid point, packing box through bonding, amount to shaping after, opening becomes an effective support rib, can strengthen the stability of putting of packing box greatly.

Above-mentioned packing box is a cube, wherein specifically can be cube, also can be cylinder or other polygon solid figure, cone etc.

Claims (4)

1, a kind of packing box, form by sheet material, sheet material is amounted to into a cube, and the side of sheet material has the outstanding base plate that constitutes box body that extends downwards, it is characterized in that: there is " U " type opening base plate and junction, side, and " U " type opening part is amounted to rib to side and nothing, in the bottom surface after the invagination closure, " U " type and side are connected as a single entity becomes the support section that stretches out of side, and separates with the bottom surface.

2, packing box according to claim 1 is characterized in that: packing box is bonding, amount to shaping after, shallow " U " shape opening becomes a support rib of strengthening firm effect between bottom and the lateral support face that is connected.

3, packing box according to claim 1 is characterized in that: above-mentioned cube is cube, cylinder, perhaps polygon solid figure.

4, packing box according to claim 1 is characterized in that: at " U " type opening that has between bottom surface and the side about a degree of depth 1mm, opening accounts for bottom surface side 3/5ths width, and the opening mid point overlaps with the base mid point.
