480. The Collapsible Box.—A box that cannot be refilled for fraudulent purposes. Must be so built that it cannot be opened without destroying it. It would be purchased by every maker of confections.
481. Bottle Stopper.—There are mines of wealth in a cheap substitute for cork. An inventor will some day make a fortune by the inventing of a paper stopper.
482. Combination Cork and Corkscrew.—A bottle stopper which can be removed by simply turning it around like the top of a wooden money-barrel made for children. Must be made to sell cheap.
483. The Collapsible Barrel.—A barrel arranged in a series of parts each one above smaller than the one below, and so contrived that when not filled the parts sink into each other like the pieces of a field glass. A barrel of such convenience for reshipping would be bought by the hundred thousand, and would be full of gold for its inventor.
484. Self-Standing Bag.—A device whereby bags will stand alone with wide-open top while being filled, thus dispensing with the services of an extra man. All shipping merchants would pay largely for such a bag.
485. Barrel Filler and Funnel Cut-Off.—Barrel filling by the ordinary funnel is slow. Provide four openings at the bottom instead of one. A small rubber hose will connect the opening of each barrel, and a cut-off or a string attachment at the end of each hose cuts off the flow when the barrel is full, and permits the contents of the hose to be carried back to the barrel and thence into one of the unfilled barrels, thus avoiding waste.
486. Folding Crate.—The transportation of fruit and other produce would be greatly facilitated and cheapened if some one would invent a folding crate. An empty crate occupies as much room as a full one.
487. Paper Barrel.—Who will invent a paper barrel which will be as serviceable as the present wooden one, and have the advantage of being light? It would have a universal sale.
Section 11. Money in Articles of Trade.
488. The Tradesman’s Signal.—An automatic device for letting the grocer, butcher, baker, etc., know when he is wanted, saving time both to the household and trade. Sure to sell.
