Description
ΪQUΪD STOCKING CONTAINER HAVING STRUCTURE FOR EASY
DRAIN
Technical Field The present invention relates to a liquid stocking container having a structure for easy drain, and more particularly, to a liquid stocking container that is designed to be lowest in height on the vertically corresponding bottom surface to thereby form a sump, whereby upon draining the corresponding liquid to an inlet hose from the main port, the rest of liquid remains smallest in amount in the container.
Background Art
As shown in FIG. 1A to 1C illustrating a conventional liquid stocking drum, the drum is formed by connecting upper and lower plates with a body and welding them. So as to drain the liquid in the drum, an inlet hose with a pump is used. At that time, the drum has a generally flat bottom surface. This causes some problems during the draining. Furthermore, since the body of the drum and the upper and lower plates thereof are welded, there is a problem that the liquid in the drum is likely to leak due to the weak connection between them. To solve this problem, many studies have been performed. This is disclosed in Korean Utility Model Registration No. 1980-0002018, which is mentioned in FIGS. 5A and 5B. As shown, a drum is made in such a manner that the bonded end parts 1 ' and 2' for a main wall 1 and a bottom plate 2 are wound outwardly to form a winding-connected part 3 and bonding-connected parts 4 and 4'. In this case, on the bonding-connected parts 4 and 4' of the main wall 1 and the bottom
plate 2 are provided protruded inside and outside wheels 5 and 5' having a generally semicircular section that are in close relation with the winding- connected part 3, such that the inside and outside protruded wheels 5 and 5' are wound and bonded to each other (The reference numerals designated in the above are limited only in FIG. 5A and 5B). However, the conventional drums or containers are developed to improve the bonding capability to prevent the leakage of the liquid therein, but is never studied to improve the structure for easily draining the liquid therefrom.
The conventional liquid drums have some problems that when the liquid is drained by using a pump 5, as shown in FIG. IB, it cannot be drained from the end of the inlet hose, with a result that the rest of liquid 4 still remains on the whole bottom surface of the drum, and that the rest of liquid 4 is processed as waste with the drum, which causes the consumption of resources and the generation of environmental contamination. In spite of the above-mentioned problems, there is no improvements or solutions for the easy draining of the liquid container. On the other hand, to reduce the quantity of the liquid remaining in the container, users often try to make the container itself inclined toward the main port. However, this makes them feel inconvenient in use, and the working efficiency becomes relatively low. In case of using a generally cylindrical container in that way, moreover, since the outer periphery of the lower plate of the container is in a generally round shape the container may be rolled in a circumferential direction, with a result that the liquid can be thrown to unexpected locations.
Disclosure of Invention
To solve the above-described problems, it is an object of the present invention to provide a liquid stocking container having a structure for easy drain that is capable of completely draining the liquid therein. It is another object of the present invention to provide a liquid stocking container having a structure for easy drain that is capable of preventing the container in the shape of a cylinder from being rolled left and right in order not to drain the liquid therein into unexpected locations, even when the container is inclined to drain all the liquid. To accomplish these and other objects of the present invention, there is provided a liquid stocking container having a structure for easy drain according to the present invention, which is provided with a sump on the lower end of a main port that is formed in such a manner that the bottom surface is lowest in a main port side and is higher than the other side, such that the area occupied by the rest of liquid on the bottom surface can be smallest, which gives the advantages of the resource savings and the reduction of wastes.
According to the present invention, there is provided a liquid stocking container having a structure for easy drain, characterized in that a predetermined area of a bottom surface corresponding vertically to a main port has a typical height (which is not changed in height), and a predetermined area spaced farthest apart from the vertically corresponding bottom surface is higher than the predetermined area of the bottom surface to thereby form a elevation portion, whereby the space between the predetermined area of the bottom surface and the elevation portion becomes inclined to form a sump on the predetermined area of the bottom surface.
With the sump on the vertically corresponding bottom surface in a typical metal or plastic container according to the present invention, the rest of liquid all gathers into the sump and all drains from the upper part of the main port by using a pumping hose. On the other hand, the liquid stocking container is selected from the group consisting of a drum, a spare bucket, a fuel tank for automobile, and a fuel tank for a boiler.
According to the present invention, in case of the liquid stocking container in the shape of a generally hexahedral bucket made of a plastic material, the predetermined area of the vertically corresponding bottom surface is set to be lower than the predetermined area spaced farthest apart from the vertically corresponding bottom surface to thereby form the sump, and in order to reduce the area of a support part for supporting the predetermined area having the higher height, the plastic material is molded over a couple of times and a process for a relatively large embossing is added to the surface of the support part.
According to the present invention, furthermore, in case of the liquid stocking container in the shape of a general round, it is provided with a straight or angular rolling prevention line on a predetermined distance of the circumferential edge of the vertically corresponding bottom surface or in the direction to which the liquid is drained.
At that time, when the round drum is inclined in the direction to which the liquid is drained, it is not rolled left and right with the formation of the rolling prevention line, thereby enabling the liquid to be drained in a stable manner.
Especially in case of a liquid stocking container in the shape of a generally cylindrical drum made of a metal material that includes a body and upper and
lower plates, the main port of the upper plate is assembled to correspond vertically to the sump on the lower plate in order for the end part of the inlet hose inserted into the main port to correspond to the sump of the lower plate. The assembling is carried out with the following steps: First, a reference mark is indicated on the edges of the upper and lower plates, respectively; second, the main port is placed on the opposite side by 180° to the reference mark on the upper plate and the sump is formed on the opposite side by 180° to the reference mark on the lower plate; third, the reference marks of the upper and lower plates correspond and fit to the joint lines welded on the body and the body and the upper and lower plates are welded or bent to each other to thereby form the final drum; and fourth, the outer surface of the drum is painted with appropriate colors. In case of the liquid stocking container made of a metal material in the shape of a general square, the step of forming the reference marks on the upper and lower plates is omitted. In case of the liquid stocking container made of a plastic material, its manufacturing process is as follows: First, a mold is formed to make the sump correspond vertically to the main port and make the height of the bottom surface higher than the sump; and second, the container is made by using the mold in a plastic injection molding manner. Moreover, in case of the liquid stocking container in the shape of a general drum, the straight or angular rolling prevention line is formed in the direction perpendicular to the center line of the sump of the lower plate in the step of manufacturing the attached parts of the container or in the step of forming the container, such that when the container with the liquid is inclined to the main port or in the direction to which the liquid is drained, it is not rolled left and right with
ease, thereby preventing the liquid from being thrown in undesirable positions.

FIGS. 5A and 5B are top plan and enlarged views showing the general shape and bonded part of the drum type of liquid stocking container according to the prior art.
Best mode for Carrying Out the Invention
Now, an explanation of the preferred embodiment of the present invention will be described with reference to accompanying drawings.
FIGS. 1A to 1C are top plan, elevation and bottom views showing a conventional drum type of liquid stocking container, and FIGS. 2A to 2C are top plan, elevation and bottom views showing a metal drum type of liquid stocking
container according to the present invention, wherein a sump 4 is formed on the lower plate 2 of the container and the upper and lower plates 3 and 2 are connected to the body 1 of the container.
Referring in detail to the process of forming the sump 4 on the lower plate 2, the container includes the body 1, the lower plate 2 and the upper plate 3. In order for a main port 5 on the upper plate 3 to correspond to the sump 4 of the lower plate 2, a joint line 8 on the body 1 for fitting into the upper plate 3 are considered as the upper and lower references on its circumference. A reference mark 6 is formed on the lower plate 2 and a reference mark 7 on the upper plate 3. In case of fitting the upper and lower plates 3 and 2 into the body 1, the joint line 8 on the body 1 corresponds to the reference mark 6 on the lower plate 2 and the reference mark 7 on the upper plate 3, and if necessary, a partially temporary fixing (for example, spot welding) is carried out thereto to prevent the jointed position from being moved or changed. So as to form the sump 4 on the lower plate 2, a mold with the shape of the sump 4 is manufactured, and also to form a rolling prevention line 9 that is arbitrarily adopted with the reference mark 6, a mold with the shape of the rolling prevention line 9 is of course manufactured. As shown in FIG. 2B, in case where the rolling prevention line 9 is selectively applied in the container according to the present invention, it is formed on the opposite side to the lower end of the joint line 8 on the body 1 or in the direction to which the liquid is drained. After connecting the upper and lower plates 3 and 2 with the body 1, the outer surface is painted. Therefore, the formation of the sump on the bottom surface of the lower plate enables the liquid in the container to all gather into the sump, without any additional external force at the time when the liquid is drained
with the help of a pumping hose. This ensures that the resources are saved and wastes are reduced.
As shown in FIGS. 4A and 4B, in case of the liquid stocking container in the shape of a generally square metal or plastic spare bucket, the predetermined area of the bottom surface of the container that corresponds vertically to the main port 5 is lower than the other side to thereby form the sump 4, and thus, a mold with the shape of the sump 4 is manufactured to form the container.
If the area for a support part 10 for supporting the predetermined area higher than the sump 4 is large, the rest of liquid may be increased. To avoid this problem, therefore, the support part 10 is molded over a couple of times and at that time, a process for forming a relatively large embossing is carried out on the surface of the support part 10 such that the damage on the surface like folds or scars can be prevented. This improves the outer appearance of the container itself. As shown in FIG. 4C, furthermore, in case of the liquid stocking container in the shape of a general round made of a plastic material, the sump according to the present invention is of course formed on the bottom surface thereof. In the same manner as mentioned above, the formation of the sump on the bottom surface enables the liquid in the container to all gather into the sump, without any additional external force at the time when the liquid is drained. This ensures that the resources are saved and wastes are reduced.
Industrial applicability
As set forth in the foregoing, there is provided a liquid stocking container made of a metal or plastic material that is provided with a sump that is formed on
the bottom surface of a lower plate such that the liquid in the container can gather into the sump, without any additional external force at the time when the liquid is drained with the help of a pumping hose. Also, in case of the liquid stocking container in the shape of a general round, there is provided a straight or angular rolling prevention line on the circumferential edge part of the bottom surface such that the container is not rolled left and right at the time when it is inclined toward the direction to which the liquid is drained, which prevents the liquid from being thrown in unexpected locations. Hence, the liquid stocking container according to the present invention ensures that the resources are saved and wastes are reduced. This gives the advantages that the material cost becomes low, the cost for treatment of waste becomes low, and the environmental contamination becomes reduced.
