Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pouring tool for a so-called gobel top container, which stores liquids such as milk, juice, sake, soy sauce, vinegar and sauce and has a gable roof top.

[0002]

2. Description of the Related Art A so-called gable top container (hereinafter simply referred to as "container") whose upper part is closed by a gable roof top is usually mainly made of paper and is widely used because of its low price. in use. However, the inside of this type of paper pack cannot be visually inspected, and it is difficult to know how much liquid is in the container, and it is necessary to judge from the weight. Therefore, the stored liquid is not used up immediately after opening, and for example, when pouring out several times so as to transfer it little by little to a tabletop container, dripping occurs due to pulsation depending on the tilt angle of the container. Or
Or there is a problem that only a small amount comes out. In addition, since it is difficult to determine the position where the liquid is poured with respect to the dish to which the liquid is poured and the liquid is likely to be scattered around, it is necessary to take great care when pouring. These are troublesome, especially when you are in a hurry.

In response to such demands, there is a roof-shaped top provided with a spout made of a synthetic resin such as polyethylene or polypropylene on one side for convenience of use a plurality of times. Further, since these containers need to be stored for a relatively long period of time after being opened, they are desired to be hermetically sealed and free from dripping during pouring. In addition, it is necessary to maintain the sealed state until the package is opened.

In response to such a demand, for example, as shown in FIG. 12, there is one in which a spouting tool 3a having a pipe-shaped round spout 4a is attached to a gable roof top 2 of a container 1. However, since there is no air hole in the spout 4a, when pouring a large amount of liquid, so-called pulsation occurs and the amount is not constant, and there is a problem that the liquid is easily scattered around. .

[0005]

Therefore, the inventor of the present application has
As shown in FIG. 13, various experiments were conducted by making a prototype in which an air hole 5a to which a pipe-shaped air intake member was connected was provided inside the extraction port. However, if the air intake member 8a provided integrally with the air hole 5a extends straight into the air space 7 in the upper part of the container 1, the liquid enters the air hole 5a at the time of pouring and air replacement is deteriorated. It has been confirmed that this is easy to do, and that this causes pulsation.

In addition, it is difficult to control the amount of the liquid to be poured out, and it is also difficult to prevent the occurrence of liquid dripping (details will be described in later-described experimental examples). Therefore, the inventor of the present application can obtain an inexpensive pour-out tool for a liquid container, which is easy to adjust the pour-out amount and which can be stably pour-out without pulsation, by further improving the air hole. did it. It is a main technical object of the present invention to provide such a spout.
