Description

  The present invention relates to a metallic container used for transporting liquid foods, medicines and the like.

  Conventionally, as a container for transporting liquid food and medicine, a metallic tank filled with liquid, a metal frame surrounding the tank, and an upper frame lid capable of stacking containers for liquid transportation A container for liquid transportation is used.

  FIG. 6 is a diagram for explaining the configuration of a conventional liquid transport container.

  In FIG. 6, reference numeral 61 denotes a main body that accommodates a transport liquid, 62 denotes a frame that supports the main body 61, and 63 denotes an upper frame lid.

  The main body has an opening 64 for pouring liquid on the upper surface thereof, and a manhole 65 is fastened to the opening 64 by a plurality of bolt members 66. A discharge port 67 is provided at the center of the bottom surface of the main body. A discharge pipe 68 is connected to the discharge port 67, and a discharge valve 69 having an opening / closing mechanism is connected to the end of the discharge port 67.

  The frame 62 includes a pallet 62a that can be transported by a forklift, a container receiver 62b that supports the main body 61, and a support column 62c. The main body 61 is accommodated in the frame 62 and placed on the container receiver 62b. Then, the upper frame lid 63 is attached so as to cover the upper ends of the four support pillars 63c.

A conventional transport metal container for liquid is configured as described above. For example, in Patent Document 1, a holding member that presses the main body is provided on the upper portion of the opposing support column, thereby holding the main body with high stability. In addition, there is disclosed one that prevents the main body from rattling during transportation.

  However, in the conventional liquid transport container, the discharge pipe is connected to the center of the bottom surface of the main body, and the discharge pipe needs to be of a certain length in order to position the discharge valve on the side surface of the main body. As a result, there has been a problem that precipitates are accumulated in the discharge pipe and it is difficult to clean the discharge pipe.

  Further, in the above conventional liquid transport container, the manhole is fixed to the main body by the bolt member. Therefore, when filling the container with the liquid object to be transported or when maintaining the inside, the operator must There is a problem that workability is very bad because all bolts must be removed and attached each time.

  Further, in the conventional liquid transport container, the upper frame lid is fixed on the frame so as to cover the four support pillars, and the upper frame lid projects from the frame. When containers are placed side by side, the capacity of the containers is poor, and in particular, the upper frame lids of adjacent liquid transport containers are caught with each other, causing damage to each other.

  Further, the liquid transport container is required to reduce the size of the entire liquid transport container in order to improve its transportability.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a container for transporting liquid that is excellent in workability and safety and can be reduced in size.

  In order to solve the above-mentioned problem, a container for transporting liquid according to claim 1 of the present invention comprises a main body portion formed by connecting a discharge pipe to a discharge port provided on a lower surface of a tank for storing liquid, and the main body portion. In a liquid transport container comprising a supporting frame frame and a top frame fixed to an upper end of the frame frame, an opening provided at an upper end of the tank is closed with a manhole, and the discharge port is It is characterized by being eccentric from the plane center of the main body to the outlet side of the discharge pipe.

  As a result, the length of the discharge pipe can be shortened, so that the residual sediment in the discharge pipe can be reduced, and the discharge pipe can be easily cleaned. Further, the overall height of the liquid transport container main body can be reduced, and the entire liquid transport container can be reduced in size.

  The container for transporting liquid according to claim 2 of the present invention is the container for transporting liquid according to claim 1, wherein the manhole is formed by a thin plate member having a cross-sectional shape, and the manhole is a band type. It is characterized by being crimped to the opening using a clamp.

  Thereby, workability at the time of filling the container body with the solution or inspecting and cleaning the inside of the container can be improved.

  Further, the liquid transport container according to claim 3 of the present invention is the liquid transport container according to claim 1 or 2, wherein the frame frame body is a rectangular frame-shaped main body on which the main body portion is placed and held. Each corner portion of the receiving frame is fixedly supported by four support columns, and four plates for fixing the top frame to the upper end portions of the four support columns. A member is fixed, and the top frame is accommodated in a quadrangular region formed by the plate member as viewed from above, and is in contact with the upper end surfaces of the four support columns by the four plate members. It is characterized by being fixedly supported.

  As a result, the entire width of the liquid transport container main body can be shortened, and the overall size of the liquid transport container can be reduced.

  The container for transporting liquid according to claim 4 of the present invention is the container for transporting liquid according to claim 3, wherein the top frame is made of four angle steels formed by bending side edges. Each corner portion of the frame body joined in a frame shape is cut out so as to form a space region between the top frame and the plate member when the top frame is fixed to the plate member, At least one through hole is provided at a position of the plate member facing the space region.

  Accordingly, it is possible to provide a liquid transport container that can be lifted without adding a special structure for engaging the lifting tool.

  According to the liquid transport container of the present invention, the discharge port of the main body of the liquid transport container is provided at a position eccentric from the center of the main body of the liquid transport container, so that the length of the discharge pipe is shortened. be able to. Thereby, the residue of the deposit in a discharge pipe can be decreased, and washing | cleaning in a discharge pipe can be made easy. Moreover, since the total height of the container body for liquid transportation can be lowered by decentering the discharge port from the center of the body of the container for liquid transportation, the entire liquid transportation container can be made compact. .

  In addition, since the manhole is formed by a thin plate having an arcuate cross section and the manhole is fixed to the main body of the liquid transport container using a clamp, the container is inspected and cleaned when it is filled with a solution. The workability at the time of performing can be improved.

  In addition, since the plate is fixed to the upper end of the frame and the top frame is fixed within the area surrounded by the plate members, it is possible to prevent the top frame from protruding outside the frame, and for liquid transportation. The size of the container can be reduced. Further, by cutting off the corner of the top frame, a space region is formed between the top frame and the plate, and a through hole is provided in a region on the plate facing the space region. A suspension tool can be inserted into the through-hole, and a liquid transport container that can be lifted can be provided without adding a special structure that enables suspension specifications.
