ABSTRACT:
A container is described, of a type which includes a resilient cover whose rearward portion is heat sealed to the flange of a container bottom or body and whose front can be bent up to gain access to the recess in the body. The cover is cut from a previously rolled sheet which is arched, and the convex side of the sheet faces upwardly so the front of the container cover tends to stay closed. The cover is heat sealed to opposite side flanges at locations lying forward of the rear of the recess by at least 25% of the length of the recess, to thereby more firmly keep the cover closed. The front of the cover and body are formed with aligned holes forward of the recess, so the container can be stored on a rod without the contents spilling out.
