A bottle-type plastic container includes a body and an opening at one end of the container that allows liquid content to be filled into the container and emptied therefrom. The body has a middle height region with front and rear surface portions, and both sides of the rear surface portion are recessed inwards and juxtaposed to each other defining a grip region therebetween. The rear surface portion of the body has a radius of curvature (R2) that is larger that a radius of curvature (R1) of the front surface portion.
