Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention has a spout that is fitted into the mouth of a bottle projecting diagonally upward, and controls the dispensing operation of the liquid content dispensed from the bottle. The present invention relates to the structure of a spouting tube that is good.

[Conventional technology]

BACKGROUND ART Recently, bottles molded from polyethylene terephthalate resin have come into wide use as bottles for storing liquids such as Japanese sake.

This bottle has a spout that is erected at the top end and projects diagonally upward to make it easier to pour out the stored liquid.
Furthermore, since the entire bottle except the mouthpiece is stored in a rectangular cylindrical presentation box made of cardboard, the appearance is arranged and the bottle is held in the presentation box. Since it can be stretch-molded with a sufficient amount of stretching to make it extremely thin, it has the advantage that the amount of consumed resin material required to mold one bottle is extremely small.

[The problem that the idea attempts to solve]

This type of bottle has the advantage of stabilizing the pouring direction of the liquid to some extent when dispensing the stored liquid because the mouthpiece is in an inclined position. When dispensing the content liquid, a breathing phenomenon occurred in the content liquid being dispensed, and as a result, the force of the content liquid being dispensed suddenly changed intermittently, making it impossible to obtain a good dispensing operation. .

Additionally, when the amount of liquid remaining in the bottle becomes low, the bottle must be brought into an almost inverted state; Since the liquid flows into the spout, the liquid to be dispensed scatters from the mouth opening, making it impossible to achieve stable and constant dispensing to a limited area.

The present invention was devised to solve the above-mentioned conventional problems, and aims to make the dispensing operation of the liquid content dispensed from the bottle stable and good.

[Means to solve the problem]

The means of the present invention for achieving the above object is a spouting tube that is fitted into the mouthpiece of a bottle body with a spout that projects diagonally upward, and the spouting tube is tightly fitted into the mouthpiece. An inner circumferential wall having approximately the same length as the outer circumferential wall is disposed within a cylindrical outer circumferential wall with a gap formed between the inner circumferential wall and the outer circumferential wall, and a bottom plate is connected between the base ends of the outer circumferential wall and the inner circumferential wall. A cylindrical part configured with a cylindrical part, and an elongated cylindrical part that is connected to the gap formed between the outer circumferential wall and the inner circumferential wall and hangs down from the bottom surface of the bottom plate of the cylindrical part with an interval between them. It consists of a ventilator section and a ventilator section.

[Effect]

The pouring tube is assembled to the mouthpiece of the bottle by forcibly and tightly fitting the outer circumferential wall into the mouthpiece of the bottle from the venting tube part. The dispensing tube with this spout has an inner peripheral wall that forms a dispensing passage for the liquid content, and a gap between the outer peripheral wall and the inner peripheral wall and a vent portion that forms an air passage. There is.

In this way, when the bottle is tilted to pour out the liquid with the spout assembled to the spout, the liquid will be poured out through the inner circumferential wall, but at this time, the liquid will be poured out through the inner peripheral wall. At least one of the cylinder parts is located above this inner circumferential wall, so when the internal pressure drops as the content liquid is poured out, this air is released from the gap formed between the outer circumferential wall and the inner circumferential wall. Outside air is continuously sucked into the bottle through the ventilation tube located at the top, and this intake of outside air into the bottle prevents the content liquid being dispensed from "breathing". This also achieves smooth dispensing of the liquid content.

In addition, since the content liquid to be dispensed flows into the inner circumferential wall through the vent pipe sections, the flow direction is regulated by the vent pipe sections, and the flow rate per unit time is regulated. As a result, the maximum flow rate and direction of the dispensed content liquid per unit time can be always stabilized.

Furthermore, since there are multiple ventilation cylinders,
When fitting and assembling the spout tube to the spout tube, at least one vent portion is always located at the upper level, even if the positioning of the spout tube with respect to the spout tube along the circumferential direction is not particularly considered. Since outside air can be sucked in without any hindrance during the operation of dispensing the contents, the operation of assembling the dispensing tube to the spout becomes easy.

〔Example〕

An embodiment of the present invention will be described with reference to the drawings.

The bottle body 1 is made of polyethylene terephthalate resin and is molded extremely thinly by biaxial stretch blow molding, and is erected with the mouth tube 2 protruding diagonally upward, and the bottle body 1 is a rectangular cylindrical shape made entirely of cardboard. When stored in the cosmetic case 3, only the spout 2 protrudes obliquely upward from the slanted wall formed at the top of the cosmetic case 3, and the protruding spout 2 secures a strong assembly with the cosmetic case 3. Achieved retention.

The spout tube 4 has a flange portion 9 at the upper end of the outer circumferential surface of the outer peripheral wall 6, which is the part to be assembled into the spout tube 2, for regulating the assembly limit position of the spout tube 4 into the spout tube 2. Six ventilation tube sections 10 are provided at equal intervals, and the mutually opposing side surfaces of each ventilation tube section 10 are flat surfaces, so that air passing between the ventilation tube sections 10 is provided. In addition, the intervals are set to a value that allows the content liquid to pass smoothly.

The ventilation hole 11 formed at the lower end of each ventilation cylinder part 10 is such that when the content liquid is poured out, the ventilation hole 11 of the ventilation cylinder part 10 located at the uppermost position is located higher, and the ventilation hole 11 is opened at the lower end of each ventilation cylinder part 10, so that the ventilation hole 11 of the ventilation cylinder part 10 located at the uppermost position is located higher, and the ventilation hole 11 is opened at the lower end of the ventilation cylinder part 10. In order to achieve smoother suction into the body 1, an opening is formed at the outer lower end of each vent tube section 10.

[Effect of idea]

Since the present invention has the above-described configuration, it exhibits the following effects.

During the dispensing operation of the liquid content, outside air is sucked into the bottle through at least one vent section, so it is possible to reliably prevent "breathing" during the dispensing operation of the liquid content. A smooth pouring operation can be obtained.

Since the flow rate and outflow direction of the content liquid to be dispensed is regulated by each vent portion, the content liquid always flows out in a constant form, thereby making it possible to obtain stable dispensing of the content liquid.

Of the multiple vent pipes provided, the vent pipe that acts to prevent "breathing" only needs to be located at the top, and by assembling the spout pipe to the spout pipe, there is always one vent pipe. Since the cylinder portion is located at the uppermost position, there is no need to consider positioning when assembling the spout tube to the spout, and therefore, assembly of the spout tube is extremely simple.

Since the flow rate of the liquid to be dispensed can be regulated by the action of multiple vent parts, when the remaining amount of liquid is low, it is possible to pour out the liquid by turning the bottle upside down. Even under such conditions, the flow rate and streamlines of the liquid to be poured out are regulated by the respective ventilation cylinders, so that the liquid can be poured out in a stable and good condition.
