A cardboard box for the packaging of fluid solid materials

Abstract

The invention discloses a cardboard box for fluid solid material packaging and relates to the technical field of fluid solid packaging. The invention includes a double-opening box body and a supporting base; a moisture-proof mechanism is fitted in the interior gap of the installation groove; a first chute, a second chute and a through hole are respectively opened on the opposite inner side of the double-opening box body; the first chute is slidably connected with The first bearing plate; the second bearing plate is slidably connected to the second bearing plate inside, and the first spring is fixedly connected to the bottom of the second bearing plate; a slide hole is opened on the side of the movable hinge column, and a protective door is slidably connected to the inside of the slide hole. Through the design of the inner door panel, the first magnet, the third magnet, the movable hinge column, the sliding hole, the protective door, the fourth magnet and the fifth magnet, the present invention can provide double protection for the articles stored in the double-open box, and when it rains, The protective door can be used to cover the top of the double-opening box to avoid the influence of a large degree of rain on the double-opening box, and greatly improve the rainproof function of the double-opening box.

Description

technical field [0001] The invention belongs to the technical field of fluid solid packaging, in particular to a cardboard box for fluid solid material packaging. Background technique [0002] There are many types of fluid solid materials, including powder, granular or loose fiber materials, a large number of loose small objects, etc. For the packaging of granular solid materials, cardboard boxes are widely used for packaging and transportation. Cardboard boxes can be seen everywhere in our life. When transporting items, the box can not only load the items, but also protect the items very well. [0003] However, the cardboard boxes in the prior art have poor moisture resistance. In humid or rainy environments, the cardboard boxes are easily affected by moisture and become soft, and moisture will enter the inside of the cardboard box to cause damage to the carried items; the existing cardboard boxes are not rainproof. function, when it rains, it can only be covered by extern...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a cardboard box for fluid solid material packaging, through the design of the moisture-proof mechanism, through hole, inner door panel, second chute, protective door, first spring and second threaded rod, the existing problem is solved. The cardboard box has poor moisture resistance and no rainproof function. When it rains, it can only be covered by external objects. The operation is troublesome and time-consuming. When encountering large vibrations, it is easy to cause damage to the items stored in the cardboard box and increase the transportation cost
