Abstract (en)
A container has a container main body and a cap member threadedly engageable with a neck portion of the container main body. The container of the present invention is characterized in that at least one of male and female screws threadedly engaged with each other is formed as such that the width of a screw groove becomes gradually smaller as it goes toward the terminal end direction of the screw, and a pressure flank and a clearance flank of the male and female screws are contacted each other under pressure at a portion where the width of the screw groove is small at the end of screwing operation. Contrary to the prior art, since the container according to the present invention is constructed as such that the screws as a whole are gradually brought to be contacted under pressure according to advancement of the screwing operation, the container main body and cap member can be surely sealed.
