Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a nozzle installed in a liquid filling device, and more particularly to a nozzle having a square tip.

BACKGROUND OF THE INVENTION In a filling device that fills a container with liquid and then seals the mouth of the container, one way to speed up the filling operation is to increase the flow rate during filling. The contents of each container varied due to spillage, the sealing surface at the mouth got wet and the seal was incomplete, and depending on the type of filling liquid, foaming became excessive, causing various problems. Therefore, the flow rate during filling was limited to a certain value or less. From this point of view, in order to quickly fill the liquid, it is conceivable to increase the number of filling nozzles or to increase the effective area of the nozzle tips. In the latter case, the tip of the nozzle is inserted into the container to reduce the distance between the nozzle and the liquid surface, but if the mouth of the container is square, there is no way to increase the effective area of the nozzle. ,
It is obvious that the shape of the tip of the nozzle should also be square.

Prior Art and its Problems From the above-mentioned viewpoint, it has been desired to make the tip of the nozzle of a liquid filling device square. It is generally made into a cylindrical shape for mounting and screwing the strainer holding cylinder (see Japanese Utility Model Application No. 55-6206). In addition, as for the rectangular type, a structure in which a rectangular cylindrical outlet was provided in the liquid container was known, but this outlet was provided integrally with the container and was attached by screwing. Nor was it equipped with a strainer (see Japanese Utility Model Application Publication No. 74512/1983). Therefore, simply combining the two structures described above does not allow the strainer to be easily attached to or removed from the tip of the nozzle.

This invention was made in view of the above points, and it not only increases the effective area of the nozzle tip, but also allows the strainer to be easily attached to or removed from the nozzle tip for replacing or cleaning the strainer. The object of the present invention is to provide a structure in which a cylindrical nozzle body is provided with a square tip.

Means for Solving the Problems A nozzle in a liquid filling device according to the present invention includes a cylindrical nozzle body 12 having a male threaded portion 15 screwed into a female threaded body 10 and a fitting projection 13 at the lower end, and a female threaded body 10. In a nozzle consisting of a rectangular cylinder 1 provided at the lower end of the rectangular cylinder 10, and a strainer 5 held at the inner lower end of the rectangular cylinder 1 by a strainer holding member 6 having a circular through hole 8 in the upper part,
A pair of outward-opening grooves 11 are provided on both sides of the lower end of the female threaded body 10, and a pair of protrusions 3 are provided on the inner surfaces of both sides of the upper end of the rectangular cylinder body 1, respectively, so as to protrude inwardly.
It is characterized in that a pair of protrusions 3 are fitted into a pair of grooves 11, and a fitting protrusion 13 of a nozzle body 12 is fitted into a circular through hole 8 of a strainer holding member 6.

Function In the nozzle according to the present invention, the pair of protrusions 3 on both sides of the upper end of the square cylinder body 1 are fitted into the pair of grooves 11 of the female thread body 10, and the fitting protrusion 13 of the nozzle body 12
is fitted into the circular through hole 8 of the strainer holding member 6. Therefore, the work of removing the strainer 5 from the nozzle body 12 for replacement or cleaning of the strainer 5 involves unscrewing the female threaded body 10 and the male threaded part 15, fitting the groove 11 and the protrusion 3, and aligning the fitting protrusion 13 with the circular shape. This can be done extremely simply by simply unfitting the through hole 8.

Moreover, since the shape of the nozzle tip is square, when filling a container with a liquid with a square mouth, the nozzle tip matches the shape of the mouth and has a large effective area. By inserting the rectangular tip into the rectangular mouth, filling of liquid can be carried out quickly.

Examples Examples of the present invention will be described in detail below. In this specification, the vertical relationship is based on FIG. 1.

1 and 2, reference numeral 1 denotes a rectangular cylinder body forming the main body of the rectangular tip of the nozzle according to the present invention, and 2
3 is a pair of left and right upper extensions provided on both sides of the upper end of the square cylinder 1, and 3 is a pair of inwardly projecting ridges formed horizontally on the upper end inner surface, that is, the opposing surface, of the pair of upper extensions 2. , 4 is an inner flange provided inside the lower end of the rectangular cylindrical body 1, 5 is a plurality of strainers held at the inner lower end of the prismatic cylindrical body 1 by the inner flange 4, and 6 is a strainer provided inside the rectangular cylindrical body 1. It is an inverted square box-shaped strainer holding member that is fitted and holds down the strainer 5. A circular through hole 8 is bored in the center of the top wall 7, and the bottom surface 9 of the top wall 7 has a large diameter downward. It has a tapered surface. Reference numeral 10 denotes a female threaded body having a rectangular outer circumferential surface, and horizontally outwardly opening grooves 11 are formed on both sides of the lower part thereof.
Further, the lower inner surface of the female threaded body 10 is a circumferential surface. A pair of inner protrusions 3 are provided in the pair of grooves 11.
is slidably fitted, and the female screw body 10 is attached to the rectangular tube body 1. 12 is a cylindrical nozzle body,
It has a fitting protrusion 13 with a small outer diameter on the lower side, and has an intermediate part 14 with a larger outer diameter on the upper side thereof,
A male threaded portion 15 is provided above this. Inset flange 1
An annular groove 16 is formed on the circumferential surface of 3, and an annular groove 16 is formed in the groove.
A ring 17 is fitted. and inset flange 1
3 is in the circular through hole 8, and the intermediate part 14 is in the female screw body 10.
The male threaded portion 15 is screwed into the female threaded body 10. Thus, the nozzle according to the present invention is constructed. The fit between the fitting protrusion 13 and the circular through hole 8 prevents the protrusion 3 from sliding against the groove 11. Also, when replacing or cleaning the strainer 5,
First, the female threaded body 10 is removed from the nozzle body 12, then the rectangular tube body 1 is removed from the male screw body 10, and the strainer 5 is extracted from the rectangular tube body 1.

Effects of the Invention According to the present invention, a pair of outward-opening grooves 11 are provided on both sides of the lower end of the female threaded body 10, and a pair of protrusions 3 are provided on the inner surfaces of both sides of the upper end of the rectangular cylinder body 1, respectively, in an inwardly protruding manner. is provided, a pair of protrusions 13 are fitted into the pair of grooves 11, and the fitting protrusion 13 of the nozzle body 12 is fitted into the circular through hole 8 of the strainer holding member 6, so that the strainer 5 can be easily replaced or cleaned. For this purpose, the work of removing the strainer 5 from the nozzle body 12 is simplified by unscrewing the female threaded body 10 and the male threaded part 15, and fitting the groove 11 with the protrusion 3 and the fitting protrusion 13 with the circular through hole 8. This can be done extremely easily by simply removing it. By making the shape of the nozzle tip square in this way, when filling a container with a liquid with a square mouth, the nozzle tip can be inserted into the container and the liquid can be filled quickly. This can shorten work time.
