Abstract

PROBLEM TO BE SOLVED: To smoothly pour a liquid at a constantly uniform flow rate without a pulsating flow by providing at least one truncated part for introducing air in the longitudinal direction along a circumferential side part from a base part of a liquid spout. SOLUTION: A truncated part 5 for introducing air is provided in the longitudinal direction from a base part of a liquid spout 4 of a container body 1 such as a PET bottle to a limited area 1 leading to an upper part of a circumferential side part 3 so that the sectional area is large at an upper part and gradually smaller to a lower part. When a liquid in the container body 1 is fed, the container body is held by hand with the truncated part 5 side for introducing air upside, and the container body 1 is tilted with the liquid spout 4 downside. Since the outside air immediately reaches the truncated part 5 for introducing air in a tilted condition of the container body immediately before pouring the liquid, the liquid spout 4 is not covered even when the liquid is fed from the liquid spout 4, and the liquid of relatively large quantity can be smoothly discharged without generating a pulsating flow.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid container capable of quickly and smoothly supplying a contained liquid without pulsation.

[0002]

2. Description of the Related Art A conventional container such as a PET bottle has a relatively large-diameter container body with respect to a small-diameter liquid inlet.
Widely used as transparent containers for juice, drinking water, etc.

[0003]

By the way, in this type of liquid container, when the container body is tilted and the liquid is injected, the liquid flowing out from the injection port cannot continuously introduce air from the outside. There was a disadvantage that the flow became a pulsating flow and the liquid could not be injected smoothly at a uniform flow rate. In particular, there was an inconvenience that a pulsating flow was likely to occur at the beginning of the injection.

[0004] Therefore, it is difficult to supply a fixed amount, and there is an inconvenience that the tabletop is often stained by spilling from a cup or the like. In particular, there is a problem that it is not possible to inject liquids well to handicapped elderly people, children and people with disabilities.

SUMMARY OF THE INVENTION The present invention has been made in view of the points described above, and has as its object to provide a liquid container capable of always performing a liquid injection in a uniform liquid supply state. It is to eliminate the inconvenience caused by the pulsating flow.

[0006]

The present invention has solved the above-mentioned problems by providing the following constitution.

(1) A container body having a desired shape, which has a bottom portion and a peripheral side portion and is provided with a liquid injection port at an upper portion and can accommodate a desired liquid,
A liquid container, characterized in that at least one cut-out portion for introducing air is vertically provided along the peripheral side portion from the base of the liquid inlet.

(2) The liquid container according to the above (1), wherein the cut-off portions for introducing air are provided two or more symmetrically.

(3) The cut-off portion for air introduction is vertically provided over a limited area from the base of the liquid inlet to the upper part on the peripheral side. Liquid container.

[0010]

Embodiments of the present invention will be described below.

First, a first embodiment will be described with reference to FIGS.

1 is a container body such as a PET bottle having a bottom portion 2 and a peripheral side portion 3 provided with a liquid inlet 4 at an upper portion, and can store and fill a desired liquid such as juice or drinking water therein.
Reference numeral 5 denotes a cut-out portion for air introduction, which is vertically provided over a limited area 1 extending from the base of the injection port 4 to the upper portion of the peripheral side portion 3, and has a cross-sectional area that is larger at the upper portion and gradually increases toward the lower portion. It is formed small. However, although not shown, the cut-out portion 5 for air introduction may be provided from the base of the liquid injection port 4 of the container body 1 to the middle or the entire area on the peripheral side.

Reference numeral 6 denotes a male screw portion for a cap (not shown) formed on the outer periphery of the liquid inlet 4. The cut-out portion 5 for air introduction is formed from the base of the male screw portion 6. .
Reference numeral 7 denotes a concave groove which is formed as necessary around the upper portion of the container body 1, and is formed as a discontinuous cutout excluding the lower end of the cut-out portion 5 for introducing air.

When the liquid in the container body 1 is supplied, the container body 1 is tilted by inclining the container body 1 by hand so that the cut-out portion 5 for air introduction faces upward. The liquid port 4 faces downward.

The surface L of the liquid in the container body 1 is inclined relative to the container body 1 while the container body 1 shifts from the state shown in FIG. 4A to the state shown in FIG. However, in the inclined state immediately before the liquid injection, the external air immediately reaches the cut-out portion 5 for air introduction from the liquid injection port 4, so that
Since the liquid supplied from the container is under the atmospheric pressure, the container body 1 is tilted until the liquid injection is started as shown in FIG. Since the liquid does not block, a relatively large amount of liquid can be smoothly discharged without pulsation.

Once the liquid injection is started in this way, the container body 1 is gently tilted thereafter from FIG. 4 (d) to (f) to discharge the liquid smoothly and uniformly. Since there is no pulsating flow, constant flow supply is also easy and disadvantages due to pulsating flow, such as liquid spill,
It can prevent dirt on the table.

The upper portion of the cut-off portion 5 for air introduction is formed to have a larger cross-sectional area than the lower portion, so that the tilting operation at the time of liquid injection can immediately increase the surface area of the liquid and increase the efficiency of the liquid injection operation. Can do well.

Incidentally, in order to clarify the inclination direction of the container body 1, the inclination direction can be indicated by an "arrow" or the like.

Next, another embodiment will be described with reference to FIG.

This embodiment has a structural feature in that two cut-out portions 5 for air introduction shown in the above-described embodiment are provided, and all other features are the same as the above-described embodiment. .

That is, the cut-off portion 5 for air introduction is provided from the four circumferences of the base of the liquid inlet 4 of the container body 1a to a desired portion of the peripheral side portion 3 (the upper limited area 1 in the drawing). The tilting direction of 1a can be increased to two places, and the product appearance of the container body 1a is improved.

The operation of the liquid container 1a of the second embodiment thus formed at the time of liquid injection is the same as that of the first embodiment, and the liquid can be supplied smoothly without pulsation. Becomes

Although not shown, the air introducing cut-out portion 5 can be further symmetrically provided with a desired number.

[0024]

Since the present invention has the above-described structure and functions, it can smoothly supply liquid without pulsating flow, and can be applied not only to ready-made PET bottles but also to all liquid containers such as glass and ceramics. It is possible to provide a liquid container that can be implemented and that can be used safely by handicapped persons such as the elderly, the disabled, and children.
