Device for clamping container

Abstract

A device for clamping container comprises a support frame positionable around the container over approximately one half of the circumference thereof, a pair of substantially horizontal support rods provided on the inner side of the frame in the vicinity of respective opposite ends thereof, and a pair of claw plates mounted on the respective support rods upwardly and downwardly rotatable. The support rods extend away from each other in a horizontal plane toward their front ends. The claw plates have inwardly curved edges opposed to each other for the body of the container to partly fit in and each have an upper surface positioned at a higher level than the support rod. The shortest distance between the claw plates through the center of the container corresponds to the diameter of the container body, and the distance between the front ends of the claw plates is smaller than the diameter. The body of the container can be clamped as by embracing merely by pushing the device against the container and is releasable merely by retracting the device from the container without necessitating any cylinder device or other drive source.
