TOOTH-POVJDER-CAN TOP.

Specification of Letters Patent.

latel'ited Feb. 2], 1911.

Application tiled May 9, 1505. Serial No. 259,63?

To all whom it may concern:

ie it known that. l, (oxnao Dniomuimain, a citizen of the United States, residing at San Francisco, in the. county of San Fran (:isco and State of California, have invented certain new and useful lmpriweinents in Tooth-Powder-t an Tops, of which the following is a specification.

This invention relates to a tooth powder can top, of that class in which the can can be opened with one hand in a single operation, and will auton'iatically close upon being released by the hand.

A 11 obj ectof? this invei'ition is to provide a tooth, powder can top of this class which can be. manufaetured at minimum cost oi? time and labor in assembling and positively fixing the several parts of the can top together.

Can tops of the class to which this improvement pertains are provided with a tele scopic cap for the closed neck of the can which neck and cap are perforated to omit the contents of the can when the cap is depressed, against the tension of a spring that normally holds the cap in extended position to close the perforations and prevent pass sage therethrough of air or other material in either direction.

In the accompanying drawing, Figure 1 is a perspective view showing the tooth powder can in use; Fig. 2 is an enlarged vertical section of the top of the can showing the same closed; Fig. 3 is a similar view showing the same open; Fig. 4 is a transverse section of the mouth of the can.

Referring to the drawing, 1 represents the body of the can which is of a cylindrical form closed at the bottom, and 2 represents the top of the can. Said top is continued into a cylindrical neck 3, closed by a top 4, concave on the outside to form a seat for a coiled spring 5. Telescoping over said neck 3 is a cap 6 the upper end of which is concaved on the inside to form a seat 7 for the upper end of said coiled spring. In the side of the neck is formed an orifice 8, and a similar orifice 9 is formed in the cap 6. The spring 5 is compressed between the seats 4 and 7, and tends to press the cap upward or away from the neck, but this movement is limited by an inwardly extending rib 10 in the side of the cap, which enters a groove 11 formed in the outside of the neck, the upper shoulder of said rib engaging the upper end of the groove to limit the upward movement of said cap on said neck. At the same time the engagement of the rib with the groove prevents the cap l. eing turned about the neck, and thus retains these parts in such posit ion that the two orifices S, 9, bear the same angular relation to the. axis of the can. These orifices are formed in the cap and neck respectively in such locations that, when the cap is depressed as far as is perinitted against the. pressure of the coiled spring, the orifice in the cap is brought im inediately over or in register with the oritic-o in the neck, thus providing a tree outlet of the powder or whatever the receptacle may contain. lint upon removing the finger from the top of the cap the spring expands, closing the orifice in the neck, and thus closing the powder can.

It. will be observed with the construction here shown the sprii'ig is entirely removed from contact with the powder while also concealed from view. Thus the can top presents a neat. and attractive appearance, at the same time the powder is maintained out of contact with the spring and prevented from being injured thereby if the spring has become rusty.

The form and arrangement of the rib 10 and groove 11 constitute an important feature of the presentinvention. It will be ob served that the inwardly extending rib 10 reaches the edge of the cap 6. It. can thus be formed in a single operation with the groove 11 by placing the parts in the position shown in Fig. 2 and then stamping the rib l0 and groove 11 in a single operation. On account of the rib 10 extending entirely to the edge of the cap 6, the groove 11 in the neck 3 can be formed by a suitable die' at the same time that the rib 10 is formed, by pressing inward both the metal. of the rib 10 and the groove 11. VVhen'this is done the cap (3 is secured upon the neck 3, and cannot be withdrawn therefrom. This enables the device to be constructed very cheaply for it consists of only three parts, the neck, the cap, and the spring, and only a single operation is required to connect these parts and to form the rib and groove which have a sliding engagement with each other.

The neck is inwardly cupped and the cap outwardly cupped, as shown, in order to hold the spring firmly in position, thus to expedite the work of assembling, and also to jection at the top of the can.

'I claim A tooth powder can top comprising a neck having an orifice and a depressed seat in its top, a cap sliding longitudinally on said neck having an upwardly lmpressed seat in its top and having an orifice in its side adapted, when the cap is depressed to register with the orifice in the neck, a spring between the head of the neck and the cap and seated in said seats and normally extending said cap, the

neck being formed with a groove on the outside, and the cap being formed with an inwardly extending rib entering said groove to prevent rotary movement of the cap on the neck, the end of the rib abutting against the end of the groove to limit the upward movement of the cap, and the rib extending entirely to the lower edge of the cap, substantially as described.

In witness whereof I have hereunto set my hand in the presence of two subscribing witnesses.
