SPECIFICATION forming part of Letters Patent No. 660,435, dated October 23, 1900.

Application filed February 3, 1900. Serial No. 3,864.. (No model.)

To fnl/Z 'whom 7115 may concern:

Be it k nowu that we,CA RL GEORGE HILGEN- BERG and HENRY REEVES LoPER, residing at Baltimore, in the State of Maryland, have in vented new and Improved Deutifrioe-Bottlc, of which the following is a specification. Bottles in which dentifrices in the form of powder or liquid are commonly sold have usually com prised a glass body and a metal 1o cap withacork stopper attached. The metalis liable to become corroded and tarnished when the goods are kept in stockfor a considerable time, whereby the bottles become so deterio-Y rated -in appearance as to be unsalable. Labels are also'generally applied in the irst instance to the necks of such bottles for the purpose of covering and concealing'the cork. Bottles have also been provided with stoppers or plugs held in place by a sort of bayonetzo joint.; but the construction was objectionable for various reasons. Plugs have likewise been constructed with central openings or passages having removable valves. We have devised an improvement upon all these forms z 5 whereby new results and advantages are attained.

In carrying out our invention we have devised a novel construction and combination of parts, as hereinafter described.

In the accompanying drawings, Figure 1 is a side View of ourimproved bottle. Fig. 2 is a central longitudinal section of the upper portion of the bottle. Fig. 3 includes perspective views of the bottle-neck, the stopper, and its plug or valve detached from each other.

The large neck 1 of the glass body 2 of our bottle has a coarse interior screw-thread 3, formed adjacent to the top or upper edge. The glass cap or stopper 4 has a corresponding exteriorthread and a lateral radial iange 5, which rests on the top of the bottle-neck 1 when the stopper 4 is screwed into place. The threads 3 3 are made very coarse and short, and the cylindrical body of the stopper is made as short as possible, so that the stopper may be inserted or removed by a slight turn or rotating movement. By making the stopper short an economy is also attained in the discharge-opening 7 of the stopper 4:, as shown 6o` in Figs. 1 and 3. The said body9 ofthe plug has a circumferential groove 10, (seeFig.v3,) and a notch 1l is provided in the adjacent lower portion of the same. This construction ada pts the plug or valve 8 to engage orlock 65 with a small conical projection 12, formed on the interior of the bottle-neck 1, Fig. 3. In inserting the plug Sit is manipulated, so that the conical projection 12 passes up through the notch 11 and into the groove 10, when 7o slight rotation of the plug 8 will obviously produce a locking engagement, so that it will be held securely in place.

It is apparent that to remove the plug'8 requires practically a reversal of the movement by which it was inserted.

The groove 10 forms a complete circle, which arrangement enables it to be readily cleaned by running astring around the valve. The rotation of the latter in the stopper may 8o also produce practically the saine result by reason of the projection l2 traversing the groove.

It will be observed that the body 9 of the valve or plug 8 is made as short as possible, 85

and the projection 12 is also located close to the top of the discharge-passage 7. This construction economizes material and reduces cost of manufacture, as before stated in the case of the stopper 4. The same advantage A9o results from dispensing with the usual lip or collar ou the bottle-neck. The lateral projection of the flange 5 of the cap or stopper 4 practically takes its place.

The bottle is designed chiefly for holding dentifrices in the form of powder, but when employed for holding liquids a cork washer 13 is required, the same being perforated and 'manufacture of the bottle.V 'Ihe saidV cap orgo'4 applied to the body of the plug, as shown. One may also be applied between the stopper et and the bottle-neck.

By the above-described construction We provide a bottle which cannot become corroded or otherwise tarnished, is more ornamental and attractive in appearance, and therefore more salable than those usually employed for the same purpose and which may be produced at less cos A special advantage is obtained by the provisionV of the stopper 4 with a ,central cylindrical passage having a corresponding valve,

both stopper and valve being securely held in place, yet adapted for eas)1 detachment by rotary manipulation.

Having thus described ourinvention, what we claim, and desire to secure by Letters Patent, is-

l. As an improved article of manufacture, the dentifrice holder or bottle comprising the glass body having a neck With a cylindrical opening, the glass cap or stopper attached thereto by a screw-thread, and having a lat ferential groove 10 extending colnpletely around it, and a notch ll leading outl and downward from said groove, as shown and described. i Y
