Packaging
It is said that the public and Congressional concern about deceptive packaging rumpus started because Senator Hart discovered that the boxes of cereals consumed by him, Mrs. Hart. and their children were be- coming higher and narrower, with a decline of net weight from 12 to 10.5 ounces. without any reduction in price. There were still twelve biscuits, but they had been reduced in size. Later. the senator rightly complained of a store - bought pie in a handsomely illustrated box that pictured. in a single slice, almost as many cherries as there were in tile whole pie.
The manufacturer who increases the unit price of his product by changing his package size to lower the quantity delivered can, without undue hardship, put his product into boxes, bags. and tins that will contain even 4 - ounce, 8 - ounce, one - pound, and two - pound quantities of breakfast foods, cake mixes, etc. A study of drugstore and supermarket shelves will convince any observer that all possible sizes and shapes of boxes, jars, bottles, and tins are in use at the same time and, as the package journals show. week by week. there is never any hesitation in introducing a new size and shape of box or bottle when it aids in product differentiation. The producers of packaged products argue strongly against changing sizes of packages to contain even weights and volumes, but no one in the trade comments unfavorably on the huge costs incurred by end- less changes of package sizes, materials, shape, art work, and net weights that are used for improving a product’ s market position.

It evidently does come high, when an average family pays about 200 dollars a year for bottles, cans, boxes, jars, and other containers, most of which can’ t be used for anything but stuffing the garbage can.
