Abstract

<P>PROBLEM TO BE SOLVED: To provide a simply structured liquid filling nozzle for filling a container with a liquid efficiently with no bubble generation. <P>SOLUTION: This liquid filling nozzle 1 for filling a container with a liquid is a liquid filling nozzle having a cylindrical body 2 with an open top and a sealable bottom. The body 2 is formed with a plurality of through holes 4 in its peripheral direction from the bottom inside wall face 5 to the bottom side face 3 of the body 2 with the axis line of the body 2 as the center. It is desirable that the holes 4 have a downward inclining angle between 60-90°. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a nozzle used for storing various liquids in a container such as a bottle or a can, and more particularly to a liquid filling nozzle for preventing foaming.

In various current industries, a large number of liquids are used. Such a liquid is filled and stored in a container such as a bottle or a can so as to be easy to use.
In order to fill the liquid, it is required that the filling density is high, the liquid is filled in a short time, and the liquid does not drip after the filling is completed.

  However, the conventional liquid filling nozzle has a structure in which the liquid is ejected from right above the liquid level in the container, so that foaming occurs, and when the liquid reaches the upper part of the container, the foamed liquid overflows from the container. In addition, the surface and the periphery of the container may be soiled and the liquid may be wasted.

Therefore, as shown in Patent Document 1, a liquid filling nozzle has been devised in which a plurality of through holes (supply holes) are formed in an expanded inclined shape on a cylindrical bottom plate. Such a liquid filling nozzle is used. However, the above problem cannot be solved, and when the liquid is filled up to a certain height, foaming occurs, and depending on the filling speed, the liquid overflows from the container as described above.
Registered Utility Model No. 3030690

  The present invention provides a liquid filling nozzle that has a simple structure, does not cause foaming, and can be efficiently filled with liquid.

The present invention relates to a liquid filling nozzle for filling a liquid, wherein an upper portion of a cylindrical body whose lower end portion can be sealed is in an open state, and the cylindrical body is centered on an axis of the cylindrical body from a lower inner wall surface to a lower side surface. The present invention relates to a liquid filling nozzle formed with a plurality of through holes in the circumferential direction.
The present invention also relates to the liquid filling nozzle, wherein the through hole is a through hole having an inclination angle of 60 to less than 90 ° in the downward direction.

  In the liquid filling nozzle according to the present invention, the liquid ejected from the nozzle is completely prevented from directly striking the liquid level in the container, and even when the liquid has foaming properties, the foamed state The liquid overflows from the container, contaminates the surface and surroundings of the container, and the liquid is not wasted.

  In the present invention, the shape and size of the through hole is arbitrarily selected depending on the size of the entire filling apparatus including the liquid filling nozzle, the liquid processing capacity, etc., but the diameter of the through hole is 1 to 3 mm. Is preferably 60 to less than 90 °, and more preferably 70 to 80 °. If the diameter of the through hole is less than 1 mm, the flow rate tends to be small, and if it exceeds 3 mm, dripping from the nozzle tends to occur.

Further, when the inclination angle of the through hole is less than 60 °, foaming tends to occur depending on the filling speed, and when it exceeds 90 °, the container tends not to be filled.
Here, the through-hole having an inclination angle of 60 to less than 90 ° in the downward direction means an angle inclined in the side surface direction of the container with respect to the bottom surface of the container as shown in FIG.

Hereinafter, the liquid filling nozzle of the present invention will be described in detail with reference to the drawings.
1 is a plan view of a liquid filling nozzle according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view taken along line AA of FIG. A plurality of through holes 4 were formed in the circumferential direction from the lower inner wall surface 5 of the cylindrical body 2 toward the lower side surface 3 around the axis of the cylindrical body 2.
In addition, the through-hole 4 formed an inclination angle of 80 ° in the downward direction.

The liquid filling nozzle according to the embodiment of the present invention is structured as described above, so that the nozzle 1 is connected to a filling valve of a conventional filling device, and the nozzle 1 is used as an inlet of a container such as a bottle or can. When the liquid is filled and filled, the liquid is ejected in an oblique direction and filled along the inner wall surface of the container if the through-hole 4 is inclined downward.
The liquid ejected from the nozzle 1 for the reasons described above does not directly hit the liquid surface in the container, and therefore does not foam even when the liquid has foaming properties.

It is a top view of the nozzle for liquid filling which becomes an Example of this invention. It is the sectional view on the AA line of FIG.
