EDWARD o. BERNERS, or Two nrvnns, WISCONSIN.

BOTTLE-CLOSURE.

To all whom it may concern:

Be it known that I, ED\VARD C. Bnnnnns, a citizen of the United States, residing at Two Rivers, in the county of Manitowoc and State of Wisconsin, have invented certain new and useful Improvements in Bottle- Olosures; and I dohereby declare the fol lowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to new and useful improvements in bottle closures and is adapted to be used in connection with bottles provided with a reduced neck in order to facilitate the application of my closure.

An importantobject of my invention is to provide a device of the above mentioned character which employs novel means for securing the closure to a bottle.

A further important object of my invention is to provide a device of the above mentioned character which is constructed of few parts, reliable in its operation and cheap to manufacture.

The above and additional objects are accomplished by such means as are illustrated in the accompanying drawings, described in the following specification, and then more particularly pointed out in the claim which is appended hereto and-forms a part of this application.

\Vith reference to the drawings, wherein I have illustrated the preferred embodiment of my invention as it is reduced to practice, and throughout the several views of which similar reference numerals designate corresponding parts: Figure l is a side elevation of my device as applied to the neck of a bottle. Fig. 2 is a vertical sectional View of my closure showing means for holding it into engagement with the neck of a bottle. Fig. 3 is a detail sectional view taken through the inner end of the closure and bottle neck showing the position of the fastening means relative to the bottle neck. Fig. 4 is a detail sectional view taken on line 4:4: of Fig. 2 showing the manner of mounting the spring catch.

Referring now more particularly to the drawings, the numeral 1 designates as an entirety the neck of a bottle which is reduced at its upper terminal, as indicated at 2, and provides an inwardly extending shoulder or flange 3 at the point of its formation with the body portion of the neck.

Specification of Letters Patent.

Application filed July 29, 1913.

Patented Mar. 17, 1914.

Serial No. 781,897.

A preferably metallic rounded cap 4E in which is mounted a cylindrical section of rubber 5 which is flattened at its upper terminal, as indicated at 6, constitutes the closure forming a part of my invention.

As a means for locking the closure in operative engagement with the bottle neck a spring catch, designated as an entirety by the numeral 7, is inserted through the rut ber section 5 centrally thereof and extends below the outer terminal of the rubber section and terminates in spaced divergent spring arms 8 which are provided with inwardly turned extremities 9 and form the rounded shoulder engaging portion 10. The spring catch 7 is formed of a single piece of resilient wire being bent centrally of its ends to provide spaced parallel portions which are extended through the rubber section 5 centrally thereof from the upper flat terminal through the rounded terminal thereof in such a way that the centrally bent portion is slightly spaced from the upper flat terminal of the rubber cap. The parallel portions described continue from the round ed terminal of the cap 5 in a divergent plane and form the divergent spring arms 8 having inwardly turned rounded extremities 9. It will thus be seen that the secure fastening of the spring catch 7 is provided and that a great resiliency is provided therefor owing to the spaced position of the parallel portions of the catch that are arranged in the central portion and through the rubber section 5.

The lower terminal of the rubber section 5 is rounded, as indicated at 11, and is adapted to engage the upper terminal of the re duced portion 2 of the bottle neck 1 and form an air tight seal when the spring catch 7 is in its operative position.

As a means to prevent the spring catch from being pulled out of the rubber section 5 a pin 12 is inserted between the upper terminal 13 of the spring catch and the rubber section 5, thereby providing the de sired action.

The manner of securing the closure to the neck of a bottle may be briefly described as follows: The catch 4; with the rubber section 5 and spring catch 7 mounted therein is applied to the reduced upper portion of the neck, and the divergent spring arms 8 of the spring catch 7 engage at their rounded shoulder engaging portions 10 the shoulder or flange 3 formed in the bottle neck and serve to hold the lower rounded portion 11 of the rubber section 5 into engagement with the upper edges of the reduced portion of the neck to provide an air tight closure.

It will thus be seen that a closure for hottles having reduced necks is provided which will accomplish all the functions recited in the foregoing specification.

In reduction to practice, I have found that the form of my invention, illustrated in the drawings and referred to in the above description, as the preferred embodiment, is the most efficient and practical; yet, realizing that the conditions concurrent with the adoption of my device will necessarily vary, I desire to emphasize the fact that various minor changes in details of construction, proportion and arrangement of parts may be resorted to, when required, without sacrificing any of the advantages of my invention, as defined in the appended claim.

Having thus described my invention, what I claim is:

In a bottle closure, the combination with a bottle neck having its upper extremity reduced to form an inwardly extending shoulder, of a closure adapted to seal the upper terminal of the neck, said closure comprising a cylindrical resilient body portion having afiat upper terminal and a rounded lower terminal, said rounded lower terminal adapted forengagement with the upper edges of the bottle neck and to extend slightly therewithin, a spring catch formed of a single piece of metal being bent centrally of its ends to provide parallel portions, said parallel portions bein extended through the body portion centra 1y thereof and arranged in spaced relation to each other the centrally bent portions of said spring catch being slightly spaced from the upper flat terminal of the body portion, said parallel portions continuing from the rounded terminal of the body portion in a downwardly extending divergent plane andv forming divergent arms, said divergent arms having their free terminals bent inwardly to provide rounded portions adapted to engage the inwardly extending shoulder of the neck, a pin mounted between the centrally bent portion and upper flat terminal of the body portion and acap fitted upon the upper portion of the body portion. In testimony whereof I aflix my signature in presence of two witnesses.
