(1) The gap between the top or bottom side flaps when stapled or glued in a closed position does not exceed one-half inch at any point in addition to the normal gap between the side flaps of an empty container when in a closed position.

(2) The top and bottom side and end flaps on container number 45B shall be 7 ¾ inches wide as measured from the score line to the edge of the flap when in a closed position.

Standard container number 45C shall be standard for lettuce and may have a slight bulge when the lettuce is first placed or packed in it as provided in this section, except that each side flap shall not exceed 7 ⅛ inches.

(3) When a closing device is used to properly close these containers, it shall only be used as a means to assist in closing the carton and is not to be used to apply pressure to the extent that any excessive bulge would be eliminated.

(4) The nonbulge lettuce containers numbers 45B and 45C may have a slight bulge, when the lettuce is first placed or packed in them, on each side, each end, the top, and the bottom. Inspections to determine the requirements of the slight bulge, when possible, shall be made at the time the lettuce is in the field. However, in cases where this is not practical or possible, inspections may be made at the cooler, prior to cooling and loading for final shipment.
