It is said that the public and Congressional concern about deceptive (欺騙性的) packaging rumpus (喧囂) started because Senator Hart discovered that the boxes of cereals consumed by him, Mrs. Hart, and their children were becoming higher and narrower, with a

　　decline of net weight from 12 to 10-1/2 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 the 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, two-pound quantities of breakfast foods, cake mixes, etc. A study of drugstore (雜貨店) 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 endless changes of package sizes, materials, shape, art work, and net weights that are used for improving a product's market position.

　　When a packaging expert explained that he was able to multiply the price of hard sweets by 2.5, from $1 to $ 2.50 by changing to a fancy jar, or that he had made a 5-ounce bottle look as though it held 8 ounces, he was in effect telling the public that packaging can be a very expensive luxury. It evidently does come high, when an average family pays about $ 200 a year for bottles, cans, boxes, jars and other containers, most of which can't be used for anything but stuffing the garbage can.
