TOOTH-POWDER BOX.

SPECIFICATION forming part of Letters Patent No. 722,699, dated March 1 '7, 1903.

' e Application filed November 22, 1901. Serial No. 83,258. (No model.)

T0 all whom, it may concern:

Be it known that LVWILLIAM HENRY HALL, a citizen of the United States of America, and a resident of the city of New York, in the State of New York, have invented anew and useful Improvement in Tooth-Powder Boxes, of which the following is a specification.

This invention relates to the caps or closures of those tooth-powder boxes or receptacles that are adapted both for shipping and storing purposes and for'dispensing the powder; and it consists in a pull-opened closure of improvedv construction, composed of two inseparable sheet-metal parts, both of which are adapted to be inexpensively made by means of dies and without milling, so as to render the closure uniformlyv powder-tight when closed and at the same time easy to open even with moist fingers.

Asheet of drawings accompanies this speciication as part thereof. Y

. Figures l and-2 are respectively front and side views of the improved box-closure closed, and Figs. 3 and 4 like views of the same open, showingit applied to an ordinary boxbody, which is represented by dotted outlines. Fig. 5 represents an axial section through the closed device on a larger scale; and Fig. 6, a cross-section on the line AB, Fig. 5. Fig. 7 represents an axial section through the opened closure on the same scale as Figs. 5 and 6; andv Fig. S, a cross-section on'the lines C D, Fig. 7. Fig. 9 represents anv axial section through the fixed cap of a modified closure, as hereinafter described.

Like letters and numbers refer to like parts in all the figures.

The improved box-closure is composed of two parts l and 2, forming, respectively, a fixed cap l and a slidiugcap 2, as they are hereinafter termed. The xed cap l is adapted by a marginal flange ot to be permanently attached to the top of a box-body 3, of sheet metal, glass, or other suitable material, before or after the same is filled with toothpowder in such a manner as to prevent refilling the box, and thus to confine the use of the box to the brand of powder indicated by its label b, Figs. l and 3. In line with the label b, so as to be unmistakably located when the box is closed, Figs. 1 and 2, the fixed cap l is constructed with an outlet o, Fig. 3 and Figs. 5 to 8, which is cut in the front ot a cylindrical neck d, having a solid or imperforate upper end e. Apart from said outlet c both parts of the improved closure are preferably and conveniently without any opening whatever, so that it is only necessary to adequately guard said outlet in order to render the closure absolutely powder-tight when closed. The sliding cap 2 is snugly iitted to said neck d, which it embraces, and is inseparately attached to the fixed cap 1 by pairs of stop projections f and grooves g, formed in the respective parts, the grooves being longitudinal and preferably and conveniently located at the sides of the closure, Figs. 2 and 4. They are thus'so placed as to distribute the strain when the sliding cap 2 is pulled open, and thus to prevent separating or loosening the sliding cap by such strain. A circumferential enlargement forms a head h on the sliding cap 2 by which to pull the closure open, as represented by the arrows in Figs. l and 2. The head h requires no milling and is otherwise adapted to be formed without interfering with the necessary powder-tight fitof the parts.

The box is closed by a downward push on the sliding cap 2, as represented bythe arrows in Figs. 3 and 4:, and is kept closed/by the frictional contact of the two parts of the closure with each other.

An annular groove in the fixed cap l to coact with the lower edge of the sliding cap 2 when the box is closed is shown at il in Figs. 5 and 7. Such groove t' is not considered necessary and may be omitted, and the shape of the fixed cap l, including that of the outlet c, may be changed as dierent makers or users may prefer, as represented by Fig. 9, and other like modifications will suggest themselves to those skilled in the art.

Having thus described said improvement, I claim as my invention and desire to patent under this specificationl. An improved pull-opened box-closure composed of two sheet-metal parts, one of which is a fixed cap having a neck with an outlet in its front and a closed upper end, and the other part is a sliding cap embracing said neck and said closed upper end and provided with a head'by which to pull it length- IOO Wise to open the box; the respective parts having stop devices indented therein to limit thelongitudinal movementofsaid slidingcap.

2. An improved pull-opened box-closure composed of two sheet-metal parts, one of which is a fixed cap having a neck with an outlet in its front and a closed upper end, and the other part is an imperforate sliding cap embracing said neck and said closed upper end and provided with a head by which to pull it lengthwise to open the box; the respective parts having indented therein diametrically opposite pairs of stop projections and longitudinal stop-grooves, to limit the longitudinal movement of said sliding cap and to distribute the pulling strain.

3. An improved pull-opened box-closure composed of two sheet-metal parts, onel of which is a fixed cap having a neck with an outlet in its front and a closed. upper end, and the other` part is an imperforate sliding cap embracing said neck and said closed upper end and provided with a head by which to pull it lengthwise to open the box; the respective part-s having stop devices indented therein to limit the opening movement of said sliding cap, and said fixed cap having an annular groove to receive the lower edge of the sliding cap when the box is closed, substantiallyr as hereinbefore specified.
