Even if it is not hygienic and the effect as a preservative is remarkable, there are some which are prohibited from being used as a preservative for hygienic reasons. In order to avoid such problems, it is possible to mix antibacterial agents with synthetic resin to form rods, and to form an antibacterial stick with a large surface area by providing irregularities on the surface, and put this in a container together with the content liquid. It is being appreciated. This antibacterial stick has the problems of increased cost due to the provision of a single member in addition to the container and the troublesome work of putting the antibacterial stick together with the contents. Further, even if the surface of the antibacterial stick is provided with irregularities, the area in contact with the contents is still insufficient, and there is a problem that the antibacterial action is not sufficient. In order to avoid the above-mentioned problems related to the rot of the contents of the conventional container, an experiment was conducted to form the container from a synthetic resin mixed with an antibacterial agent. However, although this antibacterial container has a sufficient antibacterial action on the contents, it has been reported that mold is generated on the outer surface after long-term use. Antibacterial agents are relatively expensive to manufacture and nonetheless wasteful of incorporating antibacterial agents throughout the thickness of the container, including exposed outer surfaces that do not require antibacterial action.
