Abstract

A container provided with a mouth portion having a thread for fastening a cap on the outer peripheral surface of the mouth portion is characterized in that an arc-shaped or annular horizontal recess is formed on a portion between the upper end of the thread and the upper end of the mouth portion or on the thread, and an angle (theta) of the upper wall surface of the horizontal recess relative to the vertical direction is set from 80 DEG to 150 DEG. This container provided with the mouth portion having the thread for fastening a cap can effectively prevent a content liquid from dripping along the peripheral surface of the mouth portion when the content liquid is poured out from the mouth portion, without forming a film to cover the mouth portion.

Description

technical field [0001] The present invention relates to a container having a mouth portion formed on its outer surface with threads for fastening a cap, and more particularly to a container for containing liquids such as beverages and liquid condiments. Background technique [0002] Containers can be classified into plastic containers, glass containers, metal containers and other containers according to their materials. A container formed from any material currently in wide use, having a mouth portion threadably engaged with a cap. Due to their excellent sealing ability, these containers have been widely used to contain various liquids such as beverages and liquid condiments. [0003] However, the containers for storing liquid are always accompanied by the problem of liquid dripping. Therefore, it is urgent to create an invention so that when the content liquid is poured out through the mouth, the poured liquid will not drip to the outside along the outer wall surface of t...
