Intermediate bulk container

Abstract

Provided is an intermediate bulk container which can contain and store dangerous articles such as liquid chemicals or other various kinds of liquid contents and can be vertically stacked and, more specifically, to an intermediate bulk container, wherein most of components except for vertical support bars in the intermediate bulk container, which is formed in a size capable of containing approximately one ton of content, are made of a synthetic resin material so as to reduce the total weight of the intermediate bulk container, thereby reducing manufacturing costs, and a container body made of a synthetic resin material is prevented from being ruptured or damaged, even though such intermediate bulk containers each containing approximately one ton of content are stacked in a plurality of layers, such that the stacked state can be maintained stably.

         6 . The intermediate bulk container according to  claim 3 , wherein the container, the upper cover and the lower base are made of a synthetic resin material, and the vertical support bars are made of a metal material. 
     
     
         7 . The intermediate bulk container according to  claim 6 , wherein the vertical support bars are made of a metal pipe into the shape of a semi-circular pipe, a rectangular pipe, a circular pipe or an oval pipe. 
     
     
         8 . The intermediate bulk container according to  claim 6 , wherein the horizontal support bands are made by weaving synthetic fiber, or of a synthetic resin material or a metal material. 
     
     
         9 . The intermediate bulk container according to  claim 3 , wherein upper and lower fitting parts are formed at the upper part and the lower part of the container and have a diameter, which reduces by the thickness of the outer wall parts of the upper cover and the lower base. 
     
     
         10 . The intermediate bulk container according to  claim 1 , wherein a valve mounting groove is formed at the lower end of the container, a discharge valve is coupled to the inner wall of the valve mounting groove, and the coupling of the discharge valve and the container is carried out in such a manner that, after the discharge valve, which is made in advance, is inserted into a container mold, the discharge valve is integrally coupled to the container during the molding of the container. 
     
     
         11 . An intermediate bulk container, comprising:
 a container body having a cap provided to an injection hole, which is formed in the upper part of the container body, so as to open or close the injection hole, a discharge hole formed in the inner wall of a valve mounting groove, which is formed to be dented at the lower side of the front part of the container, and a discharge valve provided to the discharge hole;   an upper cover provided in the shape of a cap to the upper part of the container body, and having a through hole formed at a position corresponding to the cap, fitting protrusions formed to be protruded at both sides of a top surface, and a plurality of support bar coupling parts formed at intervals on the entire outer circumference so as to be inserted by the upper end parts of vertical support bars;   a lower base fitted to be provided to the lower part of the container body, and having forklift fork insertion grooves formed at both sides of the lower part so as to be inserted by a forklift fork, a plurality of support bar coupling parts formed on the entire outer circumference at positions corresponding to the support bar coupling parts of the upper cover so as to be inserted by the lower end parts of the vertical support bars, and fitting grooves formed to be fitted with fitting protrusions of an intermediate bulk container to be stacked at a lower side when stacking intermediate bulk containers;   the vertical support bars provided and coupled by screws in a state, where upper and lower end parts are respectively fitted into the support bar coupling parts of the upper cover and the support bar coupling parts of the lower base, which are inserted into the upper and lower parts of the container body, so as to be coupled by screws; and   a plurality of horizontal support bands provided so as to tighten the entire outer circumferential surface of the container body, including the outer circumferential surfaces of the vertical support bars provided at intervals in the vertical direction on the outer circumferential surface of the container body.
