Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a spout that is attached to a liquid container such as an aluminum carton.

(Prior art) Conventionally, in this type of spout, the shape of the spout opening that is opened is narrowed in a part, but this part has a thin wall that forms the spout. This was the part where a ring was attached for taking it off.

(Problem to be solved by the invention) In the case of such a conventional device, when the liquid is removed from the thin wall part and the liquid content is poured out from the spout opening, air exchange is insufficient and the contents are The flow path of the liquid is not constant, which causes a so-called pulsating state. For example, in the case of sake containers, etc., when transferring to a narrow-mouthed sake bottle, etc., there is a drawback that it is easy to spill outside and is difficult to transfer. It was hot.

The present invention was devised in view of these points, and its purpose is to facilitate opening of the closing plate surrounded by a thin wall, and to prevent the liquid from pulsating. This is to ensure that it flows out smoothly.

(Means for Solving the Problems) In order to achieve the above object, the present invention specifies the shape of the spout opening and widens the protruding piece for the finger ring. Therefore, we are trying to solve this problem.

In other words, in the case of the present invention, the shape of the portion that should become the spout opening surrounded by the easily openable thin-walled part provided on the closing plate of the spout tube of the spout body is such that the shape of the spout opening is such that the shape of the spout opening is such that the shape of the spout opening, which is surrounded by the easily openable thin wall portion provided on the closing plate of the spout tube of the spout main body, is By connecting the small grip end-shaped part and the fan-shaped large part from which the liquid content flows out through a narrowed part narrower than the small part, the small part and the large part are formed separately, and the grip end A wide projecting piece for a finger ring is provided protruding along the edge of the shape.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

A is a liquid container such as an aluminum carton made of a material such as paper board laminated with aluminum foil, etc., and a spout B for dispensing the liquid content is attached to an inclined surface or the like at the top of the container.

The spout B is formed by injection molding of synthetic resin and consists of a spout body a attached to the liquid container A and a cap b screwed onto the spout body a.

The spout main body a is attached to the container main body A by a mounting seat plate 1. This mounting seat plate 1 has
When attaching the spout body A to the container body A using an automatic attachment device, a straight edge 1a is formed to serve as a reference for selecting and regulating the direction of the spout opening (described later). There is. Also, the mounting seat plate 1
There is a closing plate 3 on the inside of the pouring screw 2 which projects against the drain.

This closure plate 3 is provided with an easily openable thin part 5 from below, which becomes a pouring opening 4 when the seal is opened. The shape of the portion surrounded by the thin wall portion 5 that should become the spout opening 4 is such that when the bag is opened and becomes the spout opening 4, the small grip end-shaped portion 6 of the vat into which air flows, and the content liquid. A fan-shaped large part 7 from which the water flows out is connected by a narrowed part 8 narrower than the small part 6, and the small part 6 and the large part 7 are separated from each other via the narrowed part 8. . The direction connecting the centers of the small portion 6 and the large portion 7 is parallel to the linear edge 1a of the mounting seat plate 1 described above.

Along the outer edge of this grip end-like small portion 6, there is a wide protruding piece 9 on the inside thereof, and this is a finger hook for tearing off the portion that will become the spout opening 4 surrounded by the thin wall portion 5. A ring 10 is provided.

The cap b, which is screwed onto the spouting barrel 2 of the spout body a, has a concave portion 12 in the center of its top surface 11;
In addition, an inner cylinder 14 is placed inside the outer cylinder 13, and when this cap b is screwed onto the spout screw tube 2 with the outer cylinder 13, the spout screw tube 2 is connected to the outer cylinder 13 and the inner cylinder 14. It has come to fit in between.

In order to pour out the liquid filled and sealed in the container body A equipped with the spout B configured as described above, after unscrewing the cap B from the spouting screw 2 of the spout body A, By hooking a finger onto the finger ring 10 and pulling it, the thin wall portion 5 of the closing plate 3 is first separated from the outer edge of the small portion 6 from the root outer edge of the protruding piece 9, and then separated from the narrowed portion from both side edges. 8. The large part 7 is successively pulled apart and cut into pieces, and the spouting opening 4 is opened.

Here, when the container main body A is gently tilted with the large part 7 of the spout opening 4 facing downward, the content liquid flows out from the fan-shaped large part 7, and the content liquid of this outflow The air exchanged with the container body A flows into the container body A from the grip end-shaped small part 6 which is separated from the large part 7 at the narrow part 8.

(Effect of the invention) The present invention has the outer edge of the small grip-end-shaped part of the butt that is separated from the large fan-shaped part with the narrowed part in the part that should become the spout opening surrounded by the thin-walled part. There is a wide protruding piece for the finger ring protruding along the opening, so if you hit the opening and put your finger on the finger ring and pull it, the wide protruding piece will apply sufficient pulling force. The first fracture is easy to occur along the thin-walled portion, and this fracture progresses from the narrowed portion to the widening straight portion of the fan-shaped large portion and can be easily opened. The dispensing opening opened in this way has a small grip-end-like part and a large fan-shaped part connected by a narrowed part narrower than the small part, so that the content can be poured out. When the main body of the container is tilted during extraction, the liquid content flows out from the large part, and air instead flows in from the small part located away from the large part. The air flows out from the large fan-shaped part, and the air flows in from the small grip-end part, allowing smooth exchange between the liquid and air, which is similar to the conventional outflow port. Unlike the case where the part is slightly constricted, it is difficult to exchange the liquid with air, and the liquid flows out in a pulsating manner. Coupled with the shape, the outflow is smooth, so when the liquid inside is alcohol, for example, when transferring it to a narrow-mouthed container such as a sake bottle, it can be easily transferred without spilling to the outside.
