Description of the Related Art Small synthetic resin containers, such as sauces and soy sauce, used in ordinary households are provided with an opening-type opening and dispensing cylinder and a lid at the mouth and neck of the container (bottle). Many of them are equipped with a synthetic resin pouring tap equipped with a resin (Japanese Utility Model Laid-Open No. 4-65761). In this case, usually, a synthetic resin of a different material is used according to each function, such as a polyethylene terephthalate resin for the container body and a polyethylene resin for the spout. In addition, in order to maintain and maintain the sterilization and quality of the contents, prevent foreign substances and dust from entering the inside, and prevent mischief from mischief, it is essential that the product be sealed and prevented from falling off. Under certain conditions, the spout cannot be easily removed. Therefore, in actuality, empty containers after use are generally discarded with the spout attached.

In this case, it is necessary to separate a dispensing plug from a container made of a different material. However, the cost of reusing is considerably high because each of them is manually removed by a recycling company. On the other hand, with regard to recyclable garbage, separate collection has also become popular, and if such plastic containers can be easily removed from the container at ordinary households, the cost of reuse can be reduced. This is extremely convenient. Therefore, the present invention seeks to provide a pouring tap that has a contradictory duality of indispensable requirements for the above-mentioned product in the pouring tap and easy removal at the time of disposal. is there.

The joint ridge 4 is engaged with the engagement ridge Ab of the mouth and neck portion Aa, and the lower end surface of the outer peripheral wall 1 is brought into close proximity to the upper surface of the flange Ac of the mouth and neck portion Aa. . Then, it is distributed in the market in this state. The consumer who obtained this, when pouring out the contents,
To open the lid, pull the pull ring 13 strongly, break the closing plate 11 at the thin break line 12 for opening to obtain an opening in the closing plate 11,
The contents are discharged through the opening. After the pouring, the lid Bb may be closed. In the closed lid Bb, the closing cylinder 19 fits into the expansion dispensing cylinder 10 to close it. When the contents are used up, the empty container is discarded. In this case, the cut-and-raised ring 3 is raised upward by breaking the thin-walled fractured small pieces 5 to raise the cut-and-raised ring 3. The finger is strongly pulled upward, and a force is applied to the split part 6 from the base part 8 via the connecting piece 7 to break both the thin splitting lines 2 for splitting, and the outer peripheral wall 1 is split. As a result of the splitting, the outer peripheral wall 1 is loosely fitted to the container body neck and neck Aa.
Can be removed from Aa. By the way, when such a split state occurs on the outer peripheral wall 1 at the stage of distribution in the market, it can be easily detected from the abnormality of the cut-and-raised ring 3 or the split part 6, and it is sufficient to remove this.

In addition, not only can the required condition of the above-mentioned be maintained and secured, but also, by causing the cut-and-raised ring 3 and pulling it up strongly at the spout B, the thin-walled breaking line 2 for splitting is broken and the outer peripheral wall 1 is split. By pulling up the raising ring 3, the spout B can be easily detached from the container A. Therefore, even if the container A and the spout B are made of different materials, it can be used in general households. The port B can be easily removed, so that it can be adapted to the separate collection of the resource garbage without any trouble, the cost of reuse can be reduced, and the cost of the reuse product can be reduced.
