Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container for storing and transporting liquids, and more particularly to a drum type container including a container and a pallet which can be conveniently moved by a forklift in an interconnected form. The present invention relates to a drum type container configured to stack one or more of them and prevent their collapse.

[0002]

2. Description of the Related Art Recently, it is quite clear that dangerous goods need to be safely transported and stored. For example, it is desirable to transport environmentally hazardous and unwanted by-products created during the manufacturing process to facilities that can be removed from the manufacturing facility and properly disposed of. Removal and transportation of such environmentally hazardous products is usually accomplished using suitable containers, which have any risk of handling or transportation of hazardous products or during storage. It should not and should not be exposed to others. Hazardous material removal and transportation is usually
It will be implemented by combining large tanks and medium-sized containers. Transport of waste and chemicals is usually done by tank truck or 20
0 to 500 gallons (about 900 to 2250 liters)
Large tanks made of steel, stainless steel or plastic with a capacity range of The medium-sized shipping container according to the present invention may have a capacity of 60, 100 to 200 gallons (about 270, 450 to 900 liters),
Used in the intermediate stage of the whole transportation process. Medium containers are preferred because they can be moved or repositioned slightly during handling by the operator, but it is more important to be able to use medium containers that can be moved and lifted by mechanical devices such as forklifts. Further, it is desirable that the containers be stackable with each other to facilitate efficient utilization of warehouse space, and that the stacking can be done in a manner that does not cause relative movement of the containers. If relative movement occurs, the stacked containers will separate and possibly collapse. Also, these medium sized containers can be used as primary storage devices for collecting liquid waste from manufacturers of small quantities of hazardous materials. This sampling operation can be continued until the large container is full. It is desirable to provide convenient access means inside the container during collection of liquid waste to facilitate the injection of small amounts of waste into the container. Further, it is desirable to provide a means for venting the container while the container is in use, and to release the pressure in the container before introducing further dangerous substances into the container. It is also desirable to be able to maintain a vacuum within the container while allowing the vacuum to be released prior to the introduction of additional hazardous material into the container. In either case, after filling the container, it is desirable to provide a drainage device to conveniently remove the hazardous material from the container and dispose of it properly. Such effluent should be done so as to smooth the effluent and thereby avoid unnecessary spatter. In addition, the medium-sized container can be stored in a place such as a warehouse for a long period of time. During storage in such locations, various parts of the container, such as steel cases, wooden pallets or stands made of stainless steel, may deteriorate due to the erosion of the waste contents and the surrounding atmosphere, resulting in rusting of the container and Causes corrosion. There is a need for a medium sized container that is resistant to rusting and corrosion and whose contents can be reasonably maintained for a relatively long period of time.

It will be described with reference to FIG. 6 viewed from six directions.

The tongue and groove section 16A is shown in FIG.
It is illustrated to have a predetermined width 78 that substantially corresponds to the predetermined width 76 of the rim 56 shown in FIG. This pre-determined width 78 also applies to the legs 22, 2 described with reference to FIG.
Leg 80, 82 as described with reference to FIG. 6 as well as corresponding tongue and groove sections for 8, 30 and 32.
And also corresponds to a width of 84 tongue and groove sections. An opening 86 is provided between legs 16 and 80, an opening 88 is provided between legs 80 and 82, and an opening 9 is provided between legs 82 and 84.
0 is formed respectively. The rear portion of the pallet portion 14 is shown in FIG. 6 with strut members 92 and openings 94, 96 provided therein. These strut members 92 and openings 94, 96 provide the same benefits as in strut member 18 and openings 24 and 26 described with reference to FIG. However, strut member 92 does not have an opening like access opening 20 in strut member 18. FIG. 6 shows a bottom plan view of the strut members 18 and 92 as well as a bottom plan view of the well 46 showing the sidewalls 50B and 50C of the reservoir 50. Rim 56 and legs 16, 22, 28, 30, 32, 80, 82 and 8
The respective pre-determined widths 76, 78 complementary to each of the four are interlocking between the stacked containers 10. This will be explained in detail with reference to FIG.

FIG. 7 illustrates the situation just before placing the upper wall 54 of the container part 12 on the rim 56 of the pallet part 14. As can be seen from FIG. 7, the pallet portion 14 is oriented downwardly when its tongue and groove section, eg 16A.
Are received in and disposed within the area 54A. After the pallet portion 14 is guided downward in this area 54A, all of the leg sections, eg 16B, engage the rim 56 in abutting contact. The abutting engagement of the leg sections, the tongue and groove arrangement of the tongue and groove section of the pallet portion 14 and the rim 56 of the container portion 12 cooperate to lock the drum 10 together. The containers 10 can be stacked on top of each other. The interlocking arrangement is further described with reference to FIG. FIG. 8 illustrates a state in which one container 10 ′ is stacked on another container 10. As shown in FIG. 8, the pallet portion 14 'is placed on the upper step 62, the tongue and groove section 16A' straddles the rim 56 (not shown), and the leg 16B 'shown by its phantom line is the area. 5
It is located inside the upper step portion 62 including 4A (not shown). The container 10 of the present invention can be stacked in any column configuration suitable for short or long term storage. Openings 24, 26, 24 ', 26' are exposed in FIG. 8 to allow forklift pawls or prongs to be received thereby conveniently moving containers 10 and 10 'to any desired position. Is shown. Pallet parts 14 and 1
4'acts as a portable platform allowing the containers 10 and 10 'to be moved alone or together.

In use, referring again to FIG. 1, the container portion 12 is typically inserted through a pallet portion 14 which is united to form the container 10. The container 10 has its pallet portion 14 easily movable by a device such as a forklift. The container portion 12 has a medium volume, that is, about 60, 100 to 200 gallons (about 270, 450 gallons).
To 900 liters) for use in different manufacturing facilities where any chemicals, waste or hazardous fluids or products can be stored in this container 10 and transported to appropriate storage or disposal facilities. It can be used as a device. The containers 10 can be placed in a storage facility in a stacked state with each other. Because of the structure of the container 10, the container 10 is relatively unlikely to be deteriorated by a dangerous substance, and thus the storage life thereof can be relatively long. The container 10 is composed of a plastic material that does not have the drawbacks discussed with respect to conventional containers in the description of the prior art, such as rusting and corrosion. Furthermore, since the container 10 has a sturdy structure and its pallet portion constitutes a portable platform, a large amount of
