Abstract

The invention relates to a steady enhanced box column of a plastic fruit box, which comprises a box bottom, four-surface box walls and a corner box column, and is characterized in that: the box column is a hollow plastic column shell; a column core is formed in a hollow cavity of the plastic column shell; the column core in the box column balances the weight of the plastic box (the box column and the box walls are manufactured into a whole), so that the plastic box is steady; the column core enhances the rigidity and support strength, the weight capacity of the plastic box is greatly improved, and the plastic box is particularly suitable for stacking multiple fruit boxes and placing stably by arranging box covers; and the column core can be formed in the column shell through a preformed member or can be used as inserts to be punched in the column shell or can be formed in the column shell in other modes. Due to the column core, the wall thickness of the column shell can be thinned, so plastic materials are saved, and the cost is reduced.

Description

The steady heavier-duty box column of plastics fruit case

Technical field

The present invention relates to fruit case, particularly relate to the steady heavier-duty box column of plastics fruit case.

Background technology

The consumption of fruit case is very big, wide in variety, be mainly carton and plastics fruit case, fruit case by case at the bottom of and the four sides tank wall, and can be formed by case lid, wherein some plastics fruit case has box column in the corner of four sides tank wall, but the box column of existing plastics fruit case is the hollow posts shell, exist unsteady, poor rigidity, shortcoming such as support strength is low.If adopt the entity box column made from the plastic box commaterial, then there is the cost height, material is relatively wasted.

Summary of the invention

The objective of the invention is provides a kind of casing steady, box column good rigidly, the steady heavier-duty box column of the plastics fruit case that support strength is high in order to overcome the shortcoming that prior art exists.

The technical scheme of the steady heavier-duty box column of plastics fruit case of the present invention is: at the bottom of comprising case, four sides tank wall and corner box column, it is characterized in that described box column is the plastic column shell of hollow, has the post core in the cavity of plastic column shell.

The steady heavier-duty box column of plastics fruit case of the present invention has had the post core to the plastic box counterweight in box column, make plastic box steady, the post core increases rigidity and support strength, and weight capacity improves greatly, is specially adapted to many fruit cases and is stacked together, and the configuration case lid, place steadily.The post core can be installed in the post shell by preformed part, perhaps beats in the post shell as inserts, perhaps otherwise is positioned in the post shell.The post core has been arranged, and the post shell thickness can attenuate, saves plastic material, cost-cutting.

The steady heavier-duty box column of plastics fruit case of the present invention, described post core is coagulating cement earth pillar core or clay column core, under the post core vinyl cover is arranged.The post core price that coagulating cement earth pillar core or clay are made is low, easy to manufacture, easy for installation, by the vinyl cover sealing, the post core is positioned in the box column post shell.Described post core is that metallic material or modified plastic material are made.Metallic material can be with leftover bits and pieces manufacturings such as broken irons, and modified plastics can add manufacturings such as calcium carbonate with the waste plastics recovery material, cost-cutting.In actual product, the post core comprises that all size, length, shape (as different shapes such as circle, triangle, polygons) and various material are made.

The specific embodiment

The invention discloses a kind of steady heavier-duty box column of plastics fruit case, as shown in Figure 1-Figure 3, comprise at the bottom of the case 1, case lid 5 (generally in product, all being furnished with case lid), four sides tank wall 2 and corner box column 3, it is characterized in that described box column 3 is the plastic column shell 31 of hollow, has post core 32 in the cavity of plastic column shell.The post core has been arranged to the plastic box counterweight in box column (box column and tank wall are made one), made plastic box steady, the post core increases rigidity and support strength, and weight capacity improves greatly, and be specially adapted to many fruit cases and be stacked together, and the configuration case lid, place steadily.The post core can be installed in the post shell by preformed part, perhaps beats in the post shell as inserts, perhaps otherwise is positioned in the post shell.The post core has been arranged, and the post shell thickness can attenuate, saves plastic material, cost-cutting.Its described post core 32 is coagulating cement earth pillar core or clay column core, and plastic column lid 33 is arranged under the post core.The post core price that coagulating cement earth pillar core or clay are made is low, easy to manufacture, easy for installation, by the vinyl cover sealing, the post core is positioned in the box column post shell.Its described post core 32 is that metallic material or modified plastic material are made.Metallic material can be with leftover bits and pieces manufacturings such as broken irons, and modified plastics can add manufacturings such as calcium carbonate with the waste plastics recovery material, and cost-cutting, post core also can adopt other materials made.In actual product, the post core comprises that all size, length, shape (as different shapes such as circle, triangle, polygons) and various material are made.
