Abstract
The container of this invention has an increased strength in compression. When filled and with a closure the containers can withstand greater compressive force without a resulting deflection. This permits the use of a lighter weight and less costly shipper carton. The containers have a substantially rigid base, and except for rigidifying recesses, a substantially planar base. Further, the sidewalls of the container are substantially devoid of recesses and projections, and particularly, in the region of the base of the container. In addition, the sidewalls have a slight outward taper from an area at an upper part of the sidewall to the base of the container.
Claims14
A cylindrical-like container having a continuous sidewall, a base closing a first end of said sidewall and an opening at a second end of said sidewall having an outward taper of about 1° to about 5° from said second end to said first end and, said sidewall devoid of any one of a recess and a projection at a lower part of said sidewall, to thereby increase the compressive strength of said container when said container is substantially filled with a liquid.
