Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pallet with a discharging function for a container used for transporting various chemicals, foods and drinks, and other liquids or powders.

[0002]

2. Description of the Related Art Conventionally, a metal or plastic tank has been generally used as a container for containing and transporting liquids such as medicines and foods and drinks, but this kind of tank is quite expensive and There are problems that the efficiency of transporting and storing empty containers such as when returned from the transport destination is poor, and that it is difficult to clean for repeated use.

In particular, for discharging the liquid content,
The bottom is formed in a funnel shape, and an outlet is provided at the center of the bottom.
Although a discharge pipe with a valve is connected to this discharge port, the discharge pipe is usually integrally or firmly attached to the tank body so that it cannot be easily removed. Cleaning is particularly troublesome.

Further, when it is necessary to change the inclination of the bottom portion according to the customer's request or the difference in the type or viscosity of the liquid to be transported, it is necessary to change the entire tank, especially In the case of a plastic tank, it is necessary to change the molding die itself, which is extremely expensive.

On the other hand, in recent years, a liquid bag made of a synthetic resin film or the like is used in combination with an outer frame such as a rigid box (for example, Japanese Utility Model Laid-Open No. 6-35194), and this bag is used for each use. It has been attempted to simplify the cleaning work by disposing of the liquid bag, but the container in which the liquid bag and the outer frame are combined has a cylindrical discharge port at the lower end of the side surface of the bag. However, there is a problem that the liquid content cannot be discharged smoothly to the end.

The above-mentioned problems also apply to the powder container.

The present invention has been made in view of the above, and can be suitably used for a container for transporting liquids or powders using a bag, and a bottom portion according to the difference in the type or viscosity of the stored items. It is an object of the present invention to provide a pallet with a discharging function, which can easily meet the demands for changing the inclination degree, etc., at low cost, and can easily perform the cleaning work of the discharging pipe with a valve when repeatedly used.

[0008]

In a pallet with a discharging function for a container according to the present invention which solves the above-mentioned problems, a metal bottom receiving member capable of receiving a container bag is placed on the pallet main body. In the pallet, the bottom receiver is connected to the bottom surface of the pallet main body, which is connected to the bottom surface of the funnel-shaped bottom portion which continuously slopes inward from the rising side portions of the four circumferences and has an opening in the central portion. Fixed to the pallet body to support the bottom portion above the pallet body, a valve-equipped discharge pipe is detachably attached to the peripheral edge of the opening at the center of the bottom portion, and the attached discharge pipe is attached to the container. It is characterized in that a discharge port of the bag body is provided so as to be connectable.

In the above, it is preferable that an outer frame is provided on the upper part of the bottom receiver so as to be freely assembled. Further, on the lower surface of the peripheral edge of the opening at the center of the bottom of the bottom receiver, there is provided a locking portion into which the mounting flange provided at the end of the discharge pipe can be fitted and locked from one side. What is detachably attached by the engagement of the flange with respect to is more suitable for the cleaning work.

[0010]

The above-mentioned pallet with a discharging function of the present invention is used for a container for transporting liquids and powders stored in a bag. At this time, for example, a container bag for storing liquids and the like is a bottom receiver. Place it on top of the bag, and connect the discharge port of this bag to a discharge pipe with a valve attached to the opening peripheral edge of the bottom center of the bottom receiver, and if necessary,
An outer frame for protecting the container bag may be assembled on the bottom receiver, and the liquid, which is the object to be transported, is stored in the bag in this way and is used for transportation. At this time, the pallet body can be used to handle the load with a forklift.

The liquid or the like, which is the content at the destination of transportation, can be discharged as it is by opening the valve of the discharge pipe connected to the peripheral edge of the opening at the center of the bottom of the bottom receiver. At this time, since the bottom portion of the bottom receiver has a funnel shape, the liquid and the like in the bag body can be smoothly and efficiently discharged to the end.

When handling in an empty container such as when returning from a shipping destination, the bag can be made low by folding it low and storing it in the bottom of the bottom receiver, or by discarding it. The storage efficiency can be improved. Further, even when the outer frame is assembled on the bottom portion of the bottom receiver, the outer frame may be folded and stored on the bottom portion, and can be handled with a low bulk.

When the pallet of the present invention is repeatedly used, the pallet can be easily washed by removing the discharge pipe attached to the peripheral edge of the opening at the center of the bottom of the bottom receiver. In particular, when it is attached by the fitting locking means as in the structure of claim 3, the valve-equipped discharge pipe can be easily attached and detached.

Further, since the pallet of the present invention is constructed by combining a metal bottom support having a discharging function and a pallet, the funnel is selected according to the type of liquid, powder or the like to be transported. If you want to change the inclination of the bottom of the shape, you need only change the bottom support made of metal, and the change can be easily made by sheet metal work, and the whole container like the conventional tank made of plastic can be changed. There is no need to change to another shape or change the mold, and it is possible to easily and cost-effectively respond.
