Abstract
Abstract A container for transporting and administering flowable contents is provided with a closure comprising two panels and a closure device for positively locking the panels together. The closure device comprises an aperture having a narrow and a wide section in a first panel and an aperture-cooperating tab, hinged to a second panel. The dimensions of the tab are scaled, relative to the dimensions of the aperture, to provide the positive locking feature of this invention. The container is further provided with means for readily observing the contents level therein without the necessity for opening the closure device, these means comprising viewing orifices in one sidewall and light-admitting orifices in an opposing sidewall to provide a satisfactory levelviewing background, these orifices being so oriented on each of the respective sidewalls as to preclude substantial weakening thereof.
