The present invention relates to a drinking water container. In particular, it relates to a drinking water container that can be installed on a water server to supply the liquid of the contents to the water server side by opening the spout.

In recent years, interest in water has been increasing. For example, it is easy to use natural water or RO water for drinking, safe water for infant milk, etc. at homes, stores, or various facilities. It is said that the demand for water servers is gradually increasing for the purpose of. Along with this, the needs for drinking water containers for water servers are increasing, and various forms have been commercialized.

In many cases, a bottle filled with natural water or RO water can be attached to the water server and the required amount can be pumped out through the water intake. On the other hand, as proposed in Patent Document 1, a drinking water container using a soft material is proposed instead of using a bottle.

For example, as shown in Patent Document 1, generally, in such a container for a water server, a hole is made in the bottom of the bag by a needle provided at the bottom of a bottle holder that receives the drinking water container, and drinking water is discharged. It is designed to be poured out and stored in a cooling tank or a heating tank.

However, in such a drinking water container, a tubular drilling auxiliary member is provided at the drilled portion to prevent the needle and the drinking water container from being aligned at the time of drilling and to prevent misalignment after drilling and setting. Is required.

Further, in the distribution process, in order to prevent dust adhering to the container body in the drilling auxiliary member from being mixed into drinking water at the time of drilling, a peelable lid material is attached to the upper end of the drilling auxiliary member using an adhesive material. It was sometimes installed. Therefore, the problem related to the quality of the container before easy opening has not been solved.

However, when attached using an adhesive material, the adhesive remaining on the drilling auxiliary member after peeling may come into contact with the drinking water, so that the odor of the adhesive material may be transferred to the drinking water and cause deterioration of the taste of the drinking water. ..

Further, Patent Document 2 proposes a mouth plug and a rubber packing provided as a portion provided with a portion to be pierced into the mouth plug itself. However, if the needle is thin, it can be penetrated, but for example, when a large amount of the content liquid is to be taken out and the needle is thickened, it cannot be penetrated well. Therefore, it cannot be said that the work is stable and the opening is not easy.

In addition, Patent Document 3 proposes to open the spout of a liquid container using an insertion part having a hollow needle having a flow path inside. However, in the opening operation, a finger is attached to the pointed tip of the needle. There is a risk of accidental touching, and there is concern that it may lead to injury. Again, this is not an easy opening.

The drinking water container is not limited to the case where drinking water is filled as the content, and if it is a liquid, it can be filled in the same manner as drinking water and used as a liquid container.
