    N° 20,440 A.

The objects of this invention are to simplify the construction of the parts, and to facilitate manipulating the movable member or cap; to render the closure absolutely powder-tight when closed, so that the box may be carried 15 by travellers without danger of annoyance by the escape of powder into travelling bags and trunks; and to prevent refilling the boxes, so that manufacturers of tooth-powder may afford to sell them at low prices in connection with their contents. The improved tooth-powder box comprises a top-part, forming a neck and 20 shoulders, a body which may be of any known or improved construction, and a cap having a neck-lining integral therewith; said top-part and cap being prefer¬ ably and conveniently round in plan view and otherwise adapted to be spun up out of sheet-metal, each in one piece. The powder-outlet is formed by openings in the neck and neck-lining respec- 25 tivelv, said openings coinciding with each other when the outlet is opened, and being tightly covered respectively by solid portions of the neck-lining and neck when the outlet is closed. To facilitate manipulating the cap to open the outlet, an open slot is formed in the neck parallel with the plane of rotation of the cap and a projection to coact 30 as a stop with a closed end of said slot is formed on the neck-lining by a punching tool inserted within the neck-lining. In opening the outlet, the cap is simply turned in the proper direction until stopped by said projection. The two openings that form the powder outlet are then completely aligned with each other. When the outlet is shut, the cap is again stopped by said projection. 35 The lower end of said neck-lining is open and unobstructed, and is expanded to form a flange in contact internally with the shoulders of the top part of the box. Said flange and shoulders coact at all times to prevent the escape of powder between the neck-lining and neck, and to permanently connect the top part 40 and cap with each other by preventing the withdrawal of the neek-lining; the open inner end of the neck-lining facilitates providing it with said flange and with said stop projection by suitable tools before the top part is attached to the body and for expanding the neck-lining as a whole within the neck at the same [Price 8<7.]
