Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pouring / injecting valve and a liquid dispenser, and in particular, a flexible inner bag is housed in an outer box formed of cardboard or other thick paper, and an inner bag is used. The present invention relates to a liquid dispenser in which a pouring / injecting valve is connected to the mouth of the.

[Conventional technology]

Generally, a container for extracting an appropriate amount of an alcoholic beverage, a liquid seasoning, a soft drink or the like is provided with a spout valve. This pouring valve is designed so that the liquid in the container is not oxidized when the liquid contained therein is poured out. The present inventor previously proposed a liquid container with a pouring valve in which a closed inner bag is housed in an outer box, and a pouring valve having two valve means is attached to the mouth of the inner bag ( JP-B 57-57337, JP-B 57-5
9150, see Japanese Examined Patent Publication No. 62-29306).

[Problems to be solved by the invention]

However, in the former two of the conventional liquid containers with a pouring valve, bacteria are attached around the pouring port of the pouring valve because of the structure in which the pouring valve always projects outside the outer box. There was a problem that it was easy. Also, the latter type has a structure in which the spout valve is stored in the cosmetic case when not in use, so it is easy to keep the spout valve clean, but the fixed cylinder and the valve cylinder are external. There is a problem that the outer box tends to be large because it extends over the entire depth of the box.

Therefore, an object of the present invention is to eliminate the problems of the conventional liquid container with a pouring valve, prevent bacteria from adhering around the pouring outlet of the pouring valve, and when not in use, in an outer box. It is an object of the present invention to provide a pouring / injecting valve and a liquid dispenser which can be stored in a container and can be configured compactly by shortening the total length of the pouring valve when the valve is closed.

[Means for solving problems]

In order to achieve the above object, the pouring valve according to the present invention comprises:
A valve housing having a valve passage communicating with the inlet port at one end and having a mounting flange at the other end; and a first housing that is housed in the valve passage of the valve housing and communicates with the inlet port. A tubular valve body having a valve opening at the front end and the other end closed at a part of the peripheral wall to open the second valve opening; and a second valve opening of the valve body inserted into the valve body. It is characterized by having a pouring ring for opening and closing.

Further, the liquid dispenser according to the present invention stores the desired liquid in the outer box with the mouth of the flexible inner bag facing downward, and connects the inlet port of the valve housing to the mouth of the inner bag, In a liquid dispenser with a pouring / injecting valve in which a valve body having a first and a second valve opening is incorporated in the valve housing; the valve housing has a right cylindrical valve outer cylinder having an inlet port at its tip. , The outer cylinder of the outer cylinder is concentrically surrounded by the outer cylinder to form an annular pocket groove between the outer cylinder and the outer peripheral surface of the outer cylinder, and the main body cylinder having a helical groove in a part of the peripheral wall is joined. A mounting flange is integrally formed at the end of the main body body, and the valve body is fitted into the valve outer cylinder to close the front end and has a first valve opening in a part of the peripheral wall near the valve body. And has a valve inner cylinder having a second valve opening near the rear end A skirt portion that can be fitted into the pocket groove is integrally formed in substantially the central portion of the outer peripheral surface of the valve inner cylinder, and the helical groove can be engaged at a position on the outer diameter line of the skirt portion that is opposed to the diametric line. Different engagement pin is projected, and a pouring ring capable of opening and closing the second valve opening is rotatably fitted to the inner circumference or the outer circumference of the rear end portion of the valve body. Is.

[Work]

According to the present invention, when it is necessary to pour out an appropriate amount of liquid inside the inner bag, the valve body is rotated and the engagement pin is slid along the helical groove. , The liquid in the inner bag is first from the inlet port of the valve housing
Through the valve opening of the. Therefore, when the spout ring is rotated to align the spout and the second valve port of the valve inner cylinder with each other, an appropriate amount of the liquid stored in the inner bag can be spouted to the outside. After pouring out a desired amount of liquid, the pouring ring is rotated to close the second valve port, and then the valve body is pushed into the valve housing along the helical groove, and the valve of the valve inner cylinder is pushed. The sealing portion may be pressed against the valve seat on the valve outer cylinder side to close the first valve port.

On the other hand, when injecting a liquid beverage or the like into the sealed bag, while the valve body is pulled out from the valve housing, remove the plug and pour the liquid beverage into the valve body through the outer end opening of the valve body, A predetermined amount is filled into the sealed bag from the above part, and then the plug is closed.

Therefore, according to the present invention, since the valve body is stored inside the valve housing to be flush when not in use, dust and miscellaneous bacteria can be maintained clean without adhering to the exposed portion of the spout. At the same time, since the sealing bag and the valve chamber can be inserted with a short movement stroke of the valve cylinder, the spout valve can be made compact. Further, since the skirt portion of the valve body is inserted into the annular pocket groove of the valve housing, the axial length of the valve in the valve closed state can be shortened.
