Description

  The present invention mainly relates to a water tank for storing drinking water and considering a convenience when using the drinking water and a water supply apparatus in which a plurality of plastic tanks are stacked.

  In recent years, polytanks are widely used in various fields as containers for storing various liquids. The plastic tank is simple to manufacture and low in cost, is light and can contain a large amount of liquid, has excellent durability, and is stored in a plastic tank as a container for temporarily storing liquid. There are effects such as high convenience.

  As the most general use of the polytank, it is frequently used as a container for storing kerosene as fuel for household stoves. When kerosene is purchased at a gas station, a plastic tank containing 18 liters is used as a container. Kerosene can be put into this plastic tank and stocked at home, and the required amount can be transferred from the plastic tank to an oil stove. This transfer uses a manual or electric pump and does not lift a heavy plastic tank containing kerosene.

  On the other hand, in addition to the case of storing kerosene as fuel for a household stove, it is often used to store drinking water. Famous water called famous water is known all over the country, and many people come from all over the country looking for such water. These people carry a large 18 liter plastic tank in a car and take it home with a lot of water. A person who operates a restaurant or the like often uses natural famous water instead of tap water as water to be provided to customers. In this case, the famous water is stored in a plastic tank and taken home.

  Neighbors sometimes come to pump, so they may pump water into a small plastic container (eg 1.8 liter container) and take it home. If it is a small plastic container of 1.8 liters, it can be used easily, but if you use water in a large plastic tank containing 18 liters, you can not easily lift it by hand, for example, if you transfer it to a cup But it is very inconvenient. You can't use a manual pump to transfer kerosene to an oil stove.

  FIG. 8 shows a conventional general polytank (A). The polytank (A) has holes at two upper ends thereof, one hole is used when water is poured into the polytank (A), and the other hole can be used when water contained therein is used. A cap (b) is attached to one hole, and a bellows type hose (c) is connected to the other hole.

  Therefore, if the handle (d) formed at the upper end is gripped and the polytank (b) is lifted and tilted, water will flow out from the tip of the bellows type hose (c). However, a considerable amount of force is required to lift the 18-liter plastic tank (i), and therefore the elderly and children cannot use the water in the large plastic tank (b).

By the way, various water supply apparatuses using a polytank are known. For example, “Drinking water storage method and apparatus” according to Japanese Patent Laid-Open No. 10-131248 is a method and apparatus for securing drinking water for disasters.
If a faucet and a water storage tank are connected by a hose and water is poured, the water will fill the tank and overflow. In the present invention, if this overflowing water is returned to the faucet with a hose for daily demand, and a full water tank is made detachable, drinking water for several days at the time of disaster can be entrusted to the victim. The tank water is always the latest tap water. The apparatus of the present invention is composed only of a simple water distribution tool, a plastic tank and a hose.

Moreover, the “cap for water tank” according to Utility Model Registration No. 3019814 is easy to use with a simple structure, and can take out the water in the tank little by little and use up the water in the tank without waste. It is a cap for a water tank that can be made.
A hole is made in the central portion of the cap on the tank discharge port side (a commercially available poly tank cap has an insertion hole for attaching the attached discharge hose, and this may be used). A faucet is attached to this hole with a watertight seal through packing.

In this way, if the faucet is installed, the contained water can be drained without lifting the plastic tank, but it cannot be used up completely without leaving it.
"Drinking water storage method and apparatus" according to JP-A-10-131248 "Water tank cap" related to utility model registration No. 3019814

  Thus, in a state where water is filled in a large plastic tank for 18 liters, it is heavy and difficult to lift, and therefore, it is difficult to use the contained water. The problem to be solved by the present invention is this problem, and provides a poly tank and a water supply device that can use almost all of the contained water without lifting the large and heavy poly tank when using the contained water. To do.

  The poly tank according to the present invention is intended for a large one, but is a size that can be carried on the trunk of a passenger car and is generally a poly tank for 18 liters. In the case of a small plastic tank that can be easily lifted with one hand, there is no special inconvenience when using the contained water. Therefore, since the large and heavy plastic tank cannot be lifted and water can be poured out from the outlet hole, the water contained in the plastic tank of the present invention is made to flow out in a state of being tilted sideways.

  Therefore, an open / close valve is attached to the outlet hole and the valve is opened to allow water to flow out of the outlet hole. By the way, the outlet hole is provided on the surface (the lower surface in the collapsed state) side of the poly tank, and almost all the water in the poly tank flows out by opening the valve. Here, the specific structure of the on-off valve is not limited and can be attached to and detached from the outlet hole of the polytank.

That is, an inlet hole and an outlet hole are provided on the upper end surface of the polytank, and a cap (lid) for closing both the holes is screwed and attached. Then, the cap attached to the outlet hole can be removed and the on-off valve can be attached.
However, without providing both the inlet hole and the outlet hole, it is also possible to provide only the outlet hole and fill the polytank with water from the hole. A small air hole is provided on the side opposite to the outlet hole so that the inside of the polytank is not in a vacuum state due to the outflow of water, and the air hole is closed with a cap.

  On the other hand, the plastic tank of the present invention can be used alone, but a plurality of plastic tanks can be stacked to constitute a water supply device. In other words, the water stored in the outlet holes of the individual polytanks can be flowed out by attaching an on-off valve, and the outlet holes and the inlet holes of the respective polytanks are connected with hoses to allow the water in the upper polytanks to flow to the lower polytanks. It is also possible to do so. In this case, an opening / closing valve is attached only to the outlet hole of the lowermost poly tank.

  As described above, the plastic tank of the present invention is large and is not easy to lift in a state where it is filled with water, but it can be used in a state where it is laid down sideways. That is, by removing the cap that closes the outlet hole and attaching an on-off valve, the water contained therein can flow out naturally by opening the on-off valve. Therefore, it is not necessary to lift a heavy plastic tank containing water, and the water in the plastic tank can be used as easily as opening a tap.

And the exit hole is provided in the lower surface side of the plastic tank, and it becomes possible to use it without leaving almost all the water accommodated by opening the on-off valve. Moreover, it can stabilize without falling down by putting down a poly tank to the side, and a plurality of poly tanks can be stacked and arranged. For example, water for one week can be prepared in a poly tank for preparation.
In particular, if a water supply device is configured by stacking a plurality of plastic tanks and the outlet holes and inlet holes of the individual plastic tanks are connected by a hose, an on-off valve is attached only to the lowermost plastic tank and water from all the plastic tanks is poured out. I can do it.

The external view which shows the plastic tank which concerns on this invention. Sectional drawing of an entrance hole part. Sectional drawing of an exit hole part and an air hole part. A state where an open / close valve is attached to the outlet hole and it falls down sideways. Another embodiment showing a plastic tank according to the present invention. 3 plastic tanks stacked. Three plastic tanks are stacked and the individual plastic tanks are connected by a hose. The external view which shows the conventional poly tank.

  FIG. 1 is an embodiment showing a polytank according to the present invention, and its basic form is common to a conventional polytank. In the figure, 1 is a rectangular tank body, 2 is a handle provided on the upper end surface, 3 is an inlet hole cap, and 4 is an outlet hole cap. The tank body 1 having a rectangular parallelepiped shape is rounded so that the corners thereof are not angular, and even if they come into contact with each other, there is no injury.

  By the way, although the tank main body 1 contains water, the cap 3 for inlet holes provided in the upper end surface can be removed and can be inserted from an inlet hole. And when using the accommodated water, the cap 4 for outlet holes is removed and poured out. 2 is an enlarged sectional view of the inlet hole portion of FIG. 1, the inlet hole 5 is provided in the neutral surface of the tank body 1, and an enlarged sectional view of the outlet hole portion of FIG. 1 is shown in FIG. In addition, the outlet hole 6 is provided on the surface side of the tank body 1. That is, it is not located on the neutral surface of the tank body 1 like the inlet hole 5. A small air hole 8 is provided on the side opposite to the outlet hole 6, and an air hole cap 9 is attached to close the air hole 8.

  Since the polytank has a handle 2 on its upper end surface, it can be carried by grasping the handle 2 and placed on a car with the bottom surface 7 facing down or placed in an appropriate place. When the water is stored in the polytank and used, the polytank is arranged with the surface 10 facing down so that the outlet hole 6 is on the lower side. By arranging in this state, almost all of the water flows out from the outlet hole 6 and does not remain in the tank body 1.

  Of course, an opening / closing valve such as a faucet is attached to the outlet hole 6, and the cap 4 for the outlet hole is removed for this purpose. The outlet hole cap 4 is removed and the on-off valve is attached with the plastic tank upright, and then the surface 10 is turned down. If the on-off valve is opened, the water flows out of the on-off valve and can be used for cooking or hand-washing, which is the same as when tap water is used by opening a tap.

  FIG. 4 shows the case where the outlet hole cap 4 is removed and the on-off valve 11 is attached, and the plastic tank is tilted. Therefore, if the knob 12 is turned to open the on-off valve 11, water will flow out. However, in order to place a container (for example, a cup) below the on-off valve 11, the poly tank is set to a predetermined height. It is placed on the pedestal table, and the on-off valve 11 is opened so that the flowing water can be put. Here, the cap 9 for air holes is loosened a little so that the inside of the tank main body 1 may not be in a vacuum state due to the flow of water.

  FIG. 5 is another embodiment showing a plastic tank according to the present invention. As shown in FIG. 1, the outlet hole 4 of the plastic tank is provided so as to face the one side surface 10, and the surface 10 is formed with a concave portion and a convex portion so that they can be overlapped. That is, the one side surface 10 has a concave portion 13 and the other side surface has a convex portion. Therefore, when a plurality of polytanks are stacked, the concave portion 13 of the upper polytank is not fitted to the convex portion of the lower polytank and is not displaced. In addition, the poly tank shown in FIG. 5 is not provided with an inlet hole, and the outlet hole 8 can be used to fill the poly tank with water and to discharge the water contained from the outlet hole 8.

FIG. 6 shows a case where a plurality of plastic tanks are stacked. A mounting table 14 is placed at the lowermost end, and three plastic tanks A ₁ , A ₂ , A ₃ filled with water are stacked on the mounting table 14. Therefore, when using the water from the polytanks A ₁ , A ₂ , A ₃ , the water is used from the upper poly tank A ₃ so that the lower poly tank A ₁ is not burdened. In restaurants and restaurants, a large amount of water is used to provide to customers, but the effect is great by storing and providing famous water in the Polytank A.

  The 18-liter plastic tank A has a large storage capacity, and therefore can be sufficiently used when used as a stock container for storing water to be delivered to customers at restaurants and the like. In addition, by arranging in a tilted state instead of standing up as in the prior art, it can be stably installed without fear of falling.

FIG. 7 shows an embodiment of a water supply apparatus in which _three polytanks A ₁ , A ₂ , A ₃ are stacked and the individual polytanks A ₁ , A ₂ , A ₃ are connected by hoses 15, 15. Outlet holes 6 of the plastic tank A ₁ inlet hole 5 and plastic tank A ₂ are connected by the bellows hose 15, and is also connected by bellows hose 15 and the outlet holes 6 of the plastic tank A inlet hole 5 of the ₂ and plastic tanks A _3.

Then, the outlet holes 6 of the plastic tank A ₁ of the lowermost-off valve 11 is mounted, the water on-off valve 11 plastic tank A ₁ if open by turning the knob 12 can flow out. The poly tanks A ₁ , A ₂ , A ₃ are connected by bellows hoses 15, 15 so that the water in the upper poly tank can flow into the lower poly tank. Therefore, plastic tank A ₁ of lowermost Once emptied, all plastic tank A ₁ by feed water from the inlet hole 5 the plastic tank A _{3 uppermost,} A _2, A ₃ becomes full.

Here, the water supply method of the uppermost plastic tank A ₃ is not particularly limited, may be water from the inlet hole 5 with a conventional plastic tank illustrated in FIG. 8. Also, rather than the inlet hole 5 in the plastic tank A ₃ uppermost, may be provided a large opening in the center of the upper surface 16, it is also possible to feed water from the opening.
By the way, the bellows hose 15 has caps 17 and 18 attached to both ends thereof, the cap 17 can be screwed into the outlet hole 6 and connected, and the cap 18 can be screwed into the inlet hole 5 and connected.
