Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a container for drip-spouting a liquid having a relatively high viscosity in the form of drops, and the outer peripheral surface side of the spouting end of the drip-poured liquid The purpose is to prevent dripping due to wraparound.

[Conventional technology]

Alternatively, a liquid having a relatively high viscosity such as an edible condiment or the like needs to be made into a dripping form based on an extremely small amount of one drop when pouring out depending on the purpose of use, and a container for storing this liquid. Therefore, it is required to ensure that the drop pouring can be achieved.

A container having a so-called squeeze property, which has been widely used as a container for storing a liquid of this type, has a body portion that is elastically deformable and a mouth tube having small holes. In this case, the body is grasped in an inverted posture of the container, and the container is pressed and deformed so that the container is dripped and poured out.

[Problems to be solved by the invention]

However, the above-mentioned conventional example can certainly achieve the drop pouring of the liquid, but after completion of the drop pouring,
The liquid remaining on the opening edge of the mouth cylinder causes a liquid dripping phenomenon that flows down to the outer peripheral surface of the mouth cylinder due to its own weight, and this liquid dripping phenomenon causes the inconvenience that the outer surface of the container is soiled by the liquid. .

The liquid dripping phenomenon in this conventional example not only occurs in the above-described form, but also when the upside-down degree of the container is insufficient, that is, when the container is not sufficiently inverted, the body portion of the container body is pressed. It was also generated when the liquid was poured out.
In this case, the liquid that has been dripped and poured out wraps around the outer peripheral side of the opening end of the mouth cylinder while growing in a droplet shape at the tip of the mouth cylinder.
A large amount of liquid is left on the outer peripheral side of the opening end of the mouth cylinder according to the large adhesive force of the liquid itself, and after this residual liquid returns to the erect state, the outer peripheral surface of the container flows down by its own weight on the outer peripheral surface of the mouth cylinder. Will be polluted.

In short, since a highly viscous liquid has a large surface tension and has a large adhesive force to other objects, especially to the mouth tube, a relatively large amount of liquid is applied to the mouth edge of the mouth tube after the liquid is dripped and poured. The liquid inevitably remains in the remaining position,
The liquid remaining at the opening edge of the mouth tube flows down to the outer peripheral surface of the mouth tube according to its own weight in the erect posture of the container.

Therefore, the present invention has a technical problem to draw the liquid remaining at the end edge of the mouth tube opening after the drop pouring out to the central portion of the mouth tube opening using the adhesive force and surface tension of the liquid. It is what

[Means for solving problems]

Hereinafter, the present invention will be described with reference to the drawings showing an embodiment of the present invention.

The dripping and pouring container according to the present invention is a container for pouring out a liquid having a relatively high viscosity in a dripping manner, and is composed of a container body 1, a pouring cylinder 3 and a guide rod 8.

The container body 1 is configured by integrally erecting a mouth cylinder 2 on the upper end of a body having a squeeze property, which is a main body of the container body 1 that stores the liquid having a relatively high viscosity described above. The spout cylinder 3 is tightly assembled to the mouth cylinder 2 of the.

The spouting tubular body 3 has a configuration in which a trumpet-shaped tubular piece 4 that spreads in a trumpet shape is connected to an open end of a linear tubular piece 5 having a thin linear tubular shape.

Further, the guide rod body 8 is positioned upright with a gap serving as a passage for the liquid formed between the guide cylinder body 3 and the inner peripheral surface of the linear cylinder piece 5 described above, and the tip end thereof has a trumpet shape. It is made to project sufficiently from the tip of the tubular piece 4.

Since the tip of the guide rod body 8 that forms a gap as a passage for the liquid between the straight cylindrical piece 5 and the inner peripheral surface thereof is located sufficiently projecting from the tip of the trumpet-shaped cylindrical piece 4, the inside of the trumpet-shaped cylindrical piece 4 is located. A gap that is sufficiently larger than the gap formed between the straight tubular piece 5 and the guide rod body 8 is formed between the peripheral surface and the guide rod body 8, and therefore the pouring cylinder body is formed. At the tip of 3,
Liquid reservoir 13 where the liquid to be poured can grow in a drop shape.
Will be formed.

[Action]

Since the present invention has the above-described structure, when the container body 1 is turned upside down and the body portion is pressed to cause squeeze deformation, the liquid contained in the body portion is guided to the guide rod body 8. It passes through a narrow gap formed between the inner surface of the straight tubular piece 5 and is extruded into the liquid reservoir 13 formed at the tip of the pouring tubular body 3, where it grows in a drop shape according to the surface tension.

In the state where the container body 1 is in a sufficiently upright posture, the liquid that has grown in a droplet form in the liquid reservoir 13 flows down along the protruding guide rod body 8 when dropping due to its own weight, It will be dripped from the tip of this guide rod body 8.

In this case, the liquid portion remaining on the container side without dropping remains on the guide rod body 8, but since the guide rod body 8 stands up in the pouring tube body 3, Even if the liquid that remains adhered to the guide rod 8 flows down due to its own weight, it cannot flow out to the outer peripheral surface side of the pouring cylinder 3.

Further, when the container body 1 is not sufficiently upright and is obliquely upright, the liquid formed in the liquid reservoir 13 in the form of drops is dripped from the trumpet-shaped tube piece 4. At this time, the liquid to be dripped is separated and dripped from the tip of the trumpet-shaped tube piece 4 in a state of receiving a tensile force to the guide rod 8 by the action of the adhesive force of the liquid itself to the guide rod 8.

Therefore, the dripping liquid is the second liquid when the guide rod 8 is not provided.
Compared to the state shown by the dotted line in the figure, as shown in the solid line in FIG.
The drip will be dropped in a state in which the amount of the outer edge of the opening end of the trumpet-shaped tube piece 4 is small.

After the dropping of the liquid, the liquid remaining on the opening end edge of the trumpet-shaped tube piece 4 is attracted to the guide rod body 8 side by the action of the surface tension from the liquid that remains attached to the guide rod body 8.
It does not stop at the opening edge of the trumpet-shaped tube piece 4.

At this time, the liquid that is about to remain at the opening edge of the trumpet-shaped tube piece 4 is, as is clear from the above description of the dropping operation,
Since it can be located only at a portion where the opening edge of the trumpet-shaped tube piece 4 does not wrap around to the outside, the pulling force due to the surface tension of the liquid attached to the guide rod body 8 makes it extremely smooth. Will be sucked into.

〔Example〕

The container body 1 is formed of, for example, a soft synthetic resin so as to have a squeeze property.

The spouting cylinder 3 has an outer diameter substantially equal to the inner diameter of the mouth cylinder 2 of the container body 1, and a flange piece 6 is provided at the tip of a fitting cylinder piece 7 that is closely assembled in the mouth cylinder 2. A thin straight tubular piece 5 is continuously provided, and a trumpet-shaped tubular piece 4 is further provided at the tip thereof.

In the state where the spout barrel 3 is tightly assembled in the mouth barrel 2, the flange piece 6 is mounted on the tip surface of the mouth barrel 2.

Next, the guide rod 8 is attached to the base end of the linear tubular guide piece 9 having an outer diameter slightly smaller than the inner diameter of the linear tubular piece 5, and the assembled tubular piece 12 having an outer diameter equal to the inner diameter of the fitting tubular piece 7. The assembly cylinder piece 12 is closely assembled in the fitting cylinder piece 7, and a narrow gap is provided between the inner peripheral surface of the straight cylinder piece 5 of the pouring cylinder 3 and the guide piece 6. And the guide piece 9 is set to a length such that the tip of the guide piece 9 is sufficiently projected from the tip of the trumpet-shaped tube piece 4.

The inside of the guide piece 9 is a hollow portion 10 that communicates with the fitting tube piece 7. The hollow portion 10 communicates with the outside through a through hole 11 whose tip portion is opened laterally. Is open to the inside of the straight tubular piece 5 of the pouring tube body 3 with the guide rod body 8 assembled to the pouring tube body 3.

Therefore, when the container body 1 is turned over and the body is pressed to increase the internal pressure, the liquid flows from the fitting tube piece 7 to the hollow portion 10 and the through hole.
After passing through 11, it is extruded into a gap formed between the guide rod 8 and the inner peripheral surface of the straight tubular piece 5 and having a small area for the pouring passage, and further advances to the liquid reservoir 13.

Then, in the liquid reservoir 13, the liquid is positioned in a substantially drop shape due to the action of the surface tension according to the viscosity thereof, so that the adhesive force to the guide rod body 8 protruding ahead of the trumpet-shaped tube piece 4 is exerted. As a result, the droplet is dripped in the state of being pulled toward the guide rod body 8 and does not go around to the outer peripheral surface of the trumpet-shaped tube piece 4.

[Effect of device]

As is clear from the above description, the drip dispensing container of the present invention can dispense a liquid having a relatively high viscosity in a drip form by simply pressing the body of the container body, and the dispensing operation is stopped. Then, the liquid that did not drip will surely return to the inside of the container and will not adhere to the outer peripheral surface of the mouth cylinder as a liquid dripping phenomenon. It has many excellent effects such as easy molding.
