Benefits of technology

The present invention is for a container with a special design to prevent liquid from dripping when poured out of the container. The container has a recessed portion on the outer surface of the mouth, with an angle of up to 150 degrees. This angle prevents the liquid from flowing along the outer surface of the mouth and getting to the container. This design is easy to form and can be done with a metal mold or cutting work, making it more cost-effective than using special materials for coatings. The technical effect of this design is to prevent contamination and reduce costs while ensuring the liquid is poured out effectively.

Problems solved by technology

However, the containers containing liquids are, without exception, accompanied by a problem of liquid dripping.

Abstract

A container having a mouth portion forming, on the outer circumferential surface thereof, a screw thread for fastening a cap, wherein an arcuate or annular horizontally recessed portion is formed between the upper end of the screw thread and the upper end of the mouth portion or in the screw thread, and the angle θ of the upper wall surface of the horizontally recessed portion is set to be 80 degrees to 150 degrees relative to the vertical direction. The container has a mouth portion forming, on the outer circumferential surface thereof, a screw thread for fastening a cap without forming a coating that covers the mouth portion, and effectively prevents the liquid contained therein from dripping along the outer circumferential surface of the mouth portion when the liquid contained therein is poured out from the mouth portion.

Description

TECHNICAL FIELD[0001]This invention relates to a container having a mouth portion forming, on the outer surface thereof, a screw thread for fastening a cap, and, specifically, to a container for containing liquids such as beverages and liquid seasonings.BACKGROUND ART[0002]The containers can be classified into plastic containers, glass containers, metal containers and the like containers depending on their materials. The containers formed by using any material that have now been widely used are having a mouth portion with which a cap engages by screw. Owing to their excellent sealing capability, these containers have been widely used for containing various kinds of liquids such as beverages and liquid seasonings.[0003]However, the containers containing liquids are, without exception, accompanied by a problem of liquid dripping. Therefore, a contrivance becomes necessary so that, when the liquid contained in the container is poured out through the mouth portion, the liquid that is po...
