HENRY LEIDEL, OF NEV YORK, N. Y.

BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 558,397, dated April 14, 1896.

Application filed J' une 7, 1895.

To all whom it may con/cern.-

Beit known that I, HENRY LEIDEL, of New York city, in the county and State of New York, have invented a new and Improved Safety Bottle-Stopper, of which the following is a full, clear, and exact description.

This invention relates to that class of devices known as safety bottle-Stoppers, and designed to prevent the refilling of bottles after the contents thereof have once been removed; and the object of the invention is to provide'a device of this character of a simple and inexpensive construction, which shall present a neat appearance, and which shall be adapted to be made of glass or other fragile material, so that when once applied to a bottle for use it will be in most cases impossible of removal therefrom without breakage.

The invention consists of a valve-chamber formed or provided at the neck of the bottle, and having a valve-seat and a valve inclosed in said valve-chamber, said valve being arranged to open outward, so as to permit the contents of the bottle to be removed, but being adapted to engage said valve-seat when the bottle stands in a vertical position, so as to eifectually prevent any liquid being forced into the bottle from the outside.,

The invention also contemplates certain novel features of construction and combinations of parts, whereby certain important advantages are attained, and the bottle-stopper is made better adapted for use than other similar devices heretofore employed, all as will be Vhereinafter fully set forth.

The novel features of the invention will be carefully defined in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the gures.

Figure l is a sectional view taken axially through the neck of a bottle provided with my improved safety-stopper in its preferred form. Fig. 2 is a similar view showing a modified form of the device. Fig. 3 is a transverse section taken through the upper part of the stopper shown in Fig. 1, and Fig. 4 is a view similar to Figs. 1 and 2, but showing still another form of the improved safety-stopper.

Referring primarily to Figs. 1 and 3, 1 indicates the neck of the bottle, 'provided with serial No. 552,013. (No model.)

a plain circular mouth portion 2, the outer side of which is made to iit in a socket formed in the lower portion of a cap 3 forming the body of the stopper, which cap as well as the other parts of the stopper will be constructed of glass.

The cap 3 is annular in form and is slightly enlarged at its upper part, as indicated at 5, and at the base of saidenlarged upper part the cap 3 is provided with an interiorly-projecting annular flange 4, adapted to -rest against the top or lip of the bottle-neck, as seen in Fig. l, said lip being slightly inclined downwardly or coned toward its outer edge to form a chamber or channel into which runs and is retained a small quantity of liquid for purposes to be hereinafter explained. The cap 3 is open at its top and is adapted to be closed by a cover 6, also of annular form, provided with a central opening 7 and having around its outer part an annular depending skirt or flange S, concentric with and adapted to t inside the open upper part of the cap 3, as seen in Fig. l, and having its lower edge adapted to form a shoulder or abutment to be engaged by the outeripart of a iiat valve 10, formed of a glass disk arranged in the hollow or valve-chambell 9 of the enlarged upper por. tion 5 of the cap 3. 1

The valve 10 is of a diameter to fit loosely in the circular chamber 9 'and is adapted to seat on the inclined upper face of the flange 4 of the cap 3, and at diametrically-opposite points in its periphery said valve is provided with notched recesses or indentations 11, of a depth such that when the valve 10 is in its lowered position (seen in Fig. 1) the passage between the chamber 9 and the interior of the bottle will be closed; but when said valve is in its raised position and its edges engage the shoulder 8 of the cover 6, as when the bottle is inverted, passages will be provided Aat opposite sides of the valve, whereat the contents of the bottle may escape.

The valve will be arranged in the chamber 9 of the cap 3 and the cover G applied to said cap and secured in place either by means of cement or by a blowpipe, after which the cap itself may be secured to the bottle-neck in a similar manner, the bottle having first been filled. A cork or other stopper may then be inserted in the opening 7 in the cover 6 and IOO will serve to hold the valve lO in place on its seat and prevent it from lrattling about, whereby it might become broken, or a cap may be applied over the whole device in a well-known way.

Then it is desired-to remove the contents of the bottle, the cork or cap is removed therefrom, after which the contents may be poured out in the usual way, the valve 10 falling from its seat by gravity when the bottle is inverted in pouring and returning to its seat by gravity when the bottle is returned to its usual upright position. The inclination of the upper face of the ange or valve-seat 4 servesto collect a small volume of the liquid, which acts as a seal to close the space left between the valve 10 and its seat.

Vhen the contents of the bottle have been removed, it will be found to be impossible to refill the bottle again by removing the cap 3 therefrom, since said cap is of a fragile nature and is very securely attached, thereby rendering its removal without breakage usually impossible, so that it will be seen an eiiicient guard is provided against the reiilling of the bottle after its original contents have been withdrawn.

The construction shown in Fig. 2 is of a similar nature to that above described, except that the neck 1 of the bottle is provided with a thickened lip 12, having its upper surface beveled or inclined down and outwardly, as seen at 13, similarly to the flange 4 in the construction seen in Fig. 1, and for a similar purpose. The cap 3 is unprovided with a fiange 4 and fits over the enlarged lip 12 of the bottle-neck 1, being secured thereto by cement or by means of the blowpipe in such a position as to form a chamber 9 between the upper face 13 of said neck and the top of .the cap, which is closed, as indicated at 15,

and provided with a central opening 10 and an integral interior depending flange 14, forming a shoulder to engage the valve 10 and limit the upward movement of the saine in a manner similar to the flange or skirt 8. The said valve 10 may be of the same construction as the valve above described, and the device when applied operates in a substantially similar manner to that shown in Fig. 1.

The construction shown in Fig. 4 is very similar to the devices shown in Figs. 1 and 2, except the stopper is adapted to iit the interior of the bottle. In this form of the device the cap 8 is replaced by a cap 1S of a diame ter adapted to fit the neck 1 of the bottle, which may have a lip 17 or be otherwise formed. The cap 18 is provided at its upper part with an open-topped valve-chamber 9, closed by a cover G of substantially the form shown in Fig. 1 and containing a valve 10 similar to the valve above described. The

valve-seat 21 is beveled and formed interiorly in the cap 18, which is provided at its lower part with a conical passage 19, leading from the valve-chamber 9 into the interior of the bottle and controlled by the valve 10.

The safety-stopper constructed as above described is of an extremely simple and inexpensive construction, neat in appearance, and is not liable to become deranged or broken by ordinary usage. Moreover, it effeetually prevents the refilling of the bottle to which it is applied after the contents thereof have once been removed.

It is evident from the above description that some modification may be made in the construction and arrangement of the parts as herein set forth without material departure from the principles of the invention, and for this reason I do not wish to be understood as limiting myself to the exact form of the device as herein set forth.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patentp 1. In a safety bottle-stopper, the combina tion of a cap having a valve-chamber pro vided with a central valve-seat in its bottom and having its bottom inclined downwardly and outward from said valve-scat to form a channel surrounding the same, a perforated cover over said valve-chamber, a iiatbot tomed valve in the valve-chamber to engage said valve-seat, said valve having a diameter substantially equal to that of the valve-chamber and being provided with notches in its edges, and a stop to limit the upward movement of said valve, substantially as set forth.

2. In a safety bottlestopper, the combina tion of a cap having an open-topped valvechamberprovided with a valve-seat in its bottom, a perforated cover-plate arranged to fit over the open top of the cap, and provided with an annular stop on its under side arranged to depend inside the valve-chamber around the outer wall thereof, a valve consisting of a flat glass plate of a diameter substantially equal to that of the valve-chamber,

said valve being arranged in the valve-chamber and adapted to engage said valve-seat and to play between the valve-seat and the stop on the cover-plate, and having notches in its edges, said notches bein g of a depth adapted when the valve is in its raised position resting against the stop on the coverplate to ex tend inside the annular stop on the coverplate, substantially as set forth.
