Description

  The present invention relates to a liquid storage container such as a polyethylene terephthalate bottle (hereinafter abbreviated as a PET bottle) that stores a liquid such as water, and more particularly to the shape of the container.

  For example, empty 2 liter PET bottles are lightweight and easy to carry, and can be easily obtained. For example, simple tanks for watering potted plants, or dogs or cats It can be used as a water tank for pets.

  FIG. 5 is a top view of a conventional square PET bottle in an inverted state, and FIG. 6 is a side view of a part of the square PET bottle used as the simple tank.

As shown in these drawings, the conventional square PET bottle 50 is provided at the peripheral wall portion 51 (peripheral wall portions 51 a to 51 d) having a substantially rectangular cross-sectional shape and the lower end portion of the peripheral wall portion 51. The bottom wall portion 52 (see FIG. 6), the upper wall portion 53 provided at the upper end portion of the peripheral wall portion 51, and the liquid collecting cylinder portion 54 provided at the upper portion of the upper wall portion 53 are integrally formed. .
Reference numeral 55 in FIG. 5 is a synthetic resin cap screwed into the liquid collecting cylinder portion 54.

  The cap 55 of the empty plastic bottle 50 is removed, water 56 is put into the plastic bottle 50, and the faucet adapter 57 is inserted into the mouth portion of the liquid collecting cylinder portion 54 as shown in FIG. Confirm that the on-off valve 58 is closed.

  As shown in FIG. 6, the PET bottle 50 is placed on a stand 59 in a state of being tilted, and the faucet 60 of the faucet adapter 57 is brought out from the stand 59. One of the peripheral wall portions 51 (in the example shown in the figure, the peripheral wall portion 51a) comes into contact with the upper surface of the base 59 by tilting the PET bottle 50 and placing it on the base 59. In this state, the peripheral wall portion 51a substantially becomes a pet. It becomes the bottom of the bottle 50.

  In this state, a drinking water supply port (not shown) for watering is brought under the faucet 60 of the faucet adapter 57, and the opening / closing valve 58 of the faucet adapter 57 is opened to store in the PET bottle 50. The running water 56 can be poured automatically through the faucet adapter 57.

  When the water 56 is almost full in the pot, the on-off valve 58 is closed to stop the water supply from the plastic bottle 50, and the pot is taken to the pot for watering. When the water supply to the water is repeated, the water level in the plastic bottle 50 gradually decreases.

  By the way, as shown in FIGS. 5 and 6, the conventional plastic bottle 50 has any peripheral wall portion 51 away from the liquid collecting cylinder portion 54. When the water level drops below the liquid collection cylinder portion 54 (see FIG. 6), the water supply to the water supply cannot be performed automatically.

  Then, holding the water bottle with one hand so that the water supply port does not come off from the water tap 60 of the water adapter 57, the bottom wall 52 of the plastic bottle 50 is lifted with the other hand. It is necessary to incline the water 56 remaining in the PET bottle 50 into the water bottle, and the water supply operation becomes complicated.

  In the conventional plastic bottle 50, any of the peripheral wall portions 51 are provided outside the liquid collecting cylinder portion 54, and the plastic bottle 50 is placed in a state where the plastic bottle 50 is tilted as shown in FIG. A large step 61 is formed between one peripheral wall portion 51 (the peripheral wall portion 51a in the example shown in the figure) and the liquid collecting cylinder portion 54.

  The formation of such a large step 61 means that the amount of water 56 that can be automatically supplied by opening the opening / closing valve 58 of the faucet adapter 57 is limited. However, about half of the water 56 can be automatically supplied, but as shown in FIG. 6, the water 56 remaining in the plastic bottle 50 cannot be automatically supplied, and the plastic bottle 50 is lifted diagonally or at that time. There is a problem that the water 56 must be replenished into the PET bottle 50 again.

  An object of the present invention is to provide a liquid storage container that solves the problems of the prior art and increases the automatic supply amount of liquid from a liquid storage container such as a PET bottle and is therefore easy to handle. .

In order to achieve the above object, the present invention provides a peripheral wall provided so as to surround the periphery, a bottom wall provided at a lower end of the peripheral wall, and an upper wall provided at an upper end of the peripheral wall. And a liquid storage container having a liquid collecting cylinder portion provided on the upper portion of the upper wall portion thereof,
In the state where the liquid storage container is laid down sideways, the liquid collecting cylinder portion is provided near the lower peripheral wall portion in the horizontal shape.

  The present invention is configured as described above, and the amount of automatic supply of liquid from the liquid storage container is increased. Therefore, a liquid storage container that is easy to handle can be provided.

It is a side view in the state where the square type plastic bottle concerning the example of the present invention was turned down sideways. It is a top view in the state where the square type PET bottle was inverted. It is the side view which made the cross section the part which shows the state which utilizes the square-shaped PET bottle as a simple tank. It is a top view in the state where the square type plastic bottle concerning other examples of the present invention was inverted. It is a top view in the state where the conventional square type PET bottle was inverted. It is the side view which made the cross section the part which shows the state which utilizes the square-shaped PET bottle as a simple tank.

  FIG. 1 is a side view of a rectangular plastic bottle according to an embodiment of the present invention in a state where the plastic bottle is turned sideways, FIG. 2 is a top view of the rectangular plastic bottle in an inverted state, and FIG. It is the side view which made the cross section the part which shows the state which is utilized as a simple tank.

As shown in these drawings, the square-shaped plastic bottle 10 includes a peripheral wall portion 11 (peripheral wall portions 11 a to 11 d) having a substantially rectangular cross-sectional shape provided so as to surround the periphery, and the peripheral wall portion 11. A bottom wall portion 12 (see FIG. 3) provided at the lower end portion, an upper wall portion 13 provided at the upper end portion of the peripheral wall portion 11, and a liquid collecting cylinder portion 14 provided at the upper portion of the upper wall portion 13 ( (See FIG. 3).
Reference numeral 15 in FIGS. 1 and 2 denotes a cap that is screwed onto the liquid collecting cylinder portion 14.

  As shown in FIG. 5, the conventional square PET bottle 50 is provided with a liquid collection cylinder portion 54 at an intermediate position between the peripheral wall portions 51 a to 51 d. On the other hand, as shown in FIG. 3, the rectangular PET bottle 10 according to the present embodiment is disposed on the horizontal lower peripheral wall portion 11 a where the liquid collection cylinder portion 14 contacts the upper surface of the table 59. It is provided at a close position.

Accordingly, the peripheral wall portion 11b and the peripheral wall portion 11d on the left and right sides facing each other with the liquid collection cylinder portion 14 (cap 15) therebetween are the same as the conventional one, and the distance from the liquid collection cylinder portion 14 (cap 15) is equal. It is.
On the other hand, since the liquid collection cylinder part 14 is provided at a position close to the lower peripheral wall part 11a, the step 16 formed between the peripheral wall part 11a and the lower end part 14a of the liquid collection cylinder part 54 (FIG. 3) is negligible.
The distance between the upper peripheral wall portion 11c and the liquid collecting cylinder portion 14 (cap 15) is longer than that of the conventional case by the amount that the position of the liquid collecting cylinder portion 14 is moved downward.

  Remove the cap 15 of the emptied plastic bottle 10, put water 56 into the plastic bottle 10, and insert the faucet adapter 57 into the mouth of the liquid collection cylinder 14 as shown in FIG. 3. It is confirmed that the rotary on-off valve 58 is closed.

  As shown in FIG. 3, the PET bottle 10 is placed on a stand 59 in a state of being tilted, and the faucet 60 of the faucet adapter 57 is put out from the stand 59. By lowering the PET bottle 10 and placing it on the table 59, the lower peripheral wall portion 11 a comes into contact with the upper surface of the table 59.

  A water supply outlet (not shown) for watering is brought under the faucet 60 of the faucet adapter 57, and the open / close valve 58 of the faucet adapter 57 is opened to store in the plastic bottle 10. Water 56 can be poured automatically through the faucet adapter 57.

  When the water 56 is almost full in the pot, the on-off valve 58 is closed to stop water supply from the plastic bottle 10, and the pot is taken to the pot for watering. When water supply to the water is repeated, the water level in the plastic bottle 10 gradually decreases.

  If the liquid from the plastic bottle 10 is repeatedly taken and the water level in the plastic bottle 10 falls below the liquid collecting cylinder 14 (see FIG. 3), automatic water supply to the water bottle cannot be performed. However, in the conventional plastic bottle 50 shown in FIG. 6, since the distance from the liquid collection cylinder part 54 to the lower peripheral wall part 51a is long and the step 61 is large, the timing at which automatic water supply cannot be performed is early, and FIG. As shown, the residual amount of water 56 in the plastic bottle 50 is large.

  On the other hand, in the plastic bottle 10 according to the present embodiment, the lower peripheral wall portion 11a is close to the lower end portion 14a of the liquid collecting cylinder portion 14, and accordingly, the lower peripheral wall portion 11a and the liquid collecting cylinder portion 54 are arranged. There is very little step 16 formed between the lower end portion 14a. Therefore, most of the water 56 in the plastic bottle 10 can be taken out in a state where the plastic bottle 10 is placed horizontally (in a state where the plastic bottle 10 is laid down sideways), and the residual amount of the water 56 in the plastic bottle 10 is very small. .

  Therefore, unlike the conventional case, there is almost no need to lift the bottom wall portion 52 of the plastic bottle 50, tilt the plastic bottle 50, and pour the water 56 remaining in the plastic bottle 50 into the pot. Water supply work becomes simple.

In the case of this embodiment, it is necessary to place the peripheral wall portion 11a on the table 59 or the like with the peripheral wall portion 11a facing down. The original effect cannot be demonstrated.
Therefore, for example, “Place this side down on the outer surface of the peripheral wall 11a. ”Or, for example,“ Place this side up on the outer surface of the peripheral wall 11c. It is recommended to display a note such as “”.

FIG. 4 is a top view of a square PET bottle according to another embodiment of the present invention in an inverted state.
In this embodiment, the difference from the embodiment shown in FIG. 2 is that, in the embodiment shown in FIG. 2, the position of the liquid collecting cylinder portion 54 is brought closer to the long side peripheral wall portion 11a side. This is a point where the position of the liquid cylinder portion 54 is brought closer to the peripheral wall portion 11b (or the peripheral wall portion 11d) on the short side.
When the square-shaped PET bottle 10 is used for a simple tank or the like, considering the installation stability of the PET bottle 10, the liquid collecting cylinder portion 54 is brought closer to the long side peripheral wall portion 11a as in the embodiment shown in FIG. It ’s better.

In the said Example, although the case where the cross-sectional shape was the PET bottle 10 which has the square surrounding wall part 11 was demonstrated, this invention is not limited to this, For example, a cross-sectional shape has a substantially semicircle-shaped surrounding wall part. Applicable to PET bottles.
In this case, it is necessary to bring the liquid collecting cylinder portion close to the horizontal peripheral wall portion of the substantially semicircular peripheral wall portion.

  In the above-described embodiment, the faucet adapter 57 having the rotary on-off valve 58 is used. However, a faucet adapter having a push-type on-off valve that opens when the push is released and the on-off valve closes when the press is released may be used. Is possible.

  In the above-described embodiment, an example in which a PET bottle is used as a small and simple tank for watering potted plants has been described. However, the present invention is not limited to this, and for example, a pet as a simple tank for supplying water to a pet or the like. It is also possible to use bottles.

  In the above-described embodiment, an example in which water is stored in a plastic bottle has been described. However, the present invention is not limited to this, and can be used as a liquid storage container for storing liquids other than water, such as detergent liquid. It is.

  In the above embodiment, the liquid storage container made of synthetic resin such as a plastic bottle has been described. However, the present invention is not limited to this, and the liquid storage container formed of a material other than the synthetic resin such as a metal thin plate is also applicable. Applicable.
