Specification of Letters Patent.

Patented Jan. 3(1 row.

Application filed August 5, 1911. Serial No. 642,499.

To all whom it may concern:

Be it known that I, AARoN SEGALL, a citizen of the United States of America, residing at Manhattan, New York city, New York, have invented certain new and useful Improvements in Sanitary Bottle-Caps, of which the following is a specification.

The drawing is a side view, partly in sec tion, of the upper part of a bottle covered by a cap embodying the features of my invention.

In the form shown, my cap consists of a disk 26, adapted to be inserted within the neck of a bottle and to close the opening of said neck. From the line of that disk there is an upwardly extending flange, sufliciently long to reach the top of the bottle. The disk 26 and the flange are shown as though made of pieces originally separate, but that is not necessary. That was done in this instance to conveniently accommodate the cap to the form of bottle with a recess in the neck as shown in the drawing. The upwardly extending flange conforms in shape to the opening in the neck of the bottle and is constructed to fit snugly therein, the purpose being that it shall fit so as to hold the cap upon the bottle and to insure that result, I construct it with a sharp angle at the cornor wherethis upwardly extending flange and the part closing the neck of the bottle come together, as shown at 27. From the top of this upwardly extending flange, a-

horizontal flange extends outward to or near the outer line of the lip of the bottle. The presence of such flange prevents any dust from settling upon the upper part of the bottle lip and when the cap is removed the bottle will be entirely clean. From this flange, if desired, a further flange 28 may extend down along the outside of the bottle and furnish a further grip to hold the cap in place. The result is that there is a double holding of the cap to the bottle, sufliciently strong to prevent any extensive displacement. Sometimes I run this outer flange down sufliciently to extend in under the outer face of the lip of the bottle and in such case, to permit its easy removal, I slit the material of that flange, as shown at 30. The slits 30 will permit the material of the cap to yield sufliciently to allow of its withdrawal and yet, since the lower edge is integral, the cap is more durable and less liable to be torn apart.

The cap is shown as though the disk part 25 and the remainder of the cap were separate pieces; they are however, in fact, substantially integral, having been preferably made of celluloid and fastened together when in such condition as to result in their permanent cohesion.

As it is sometimes difl'icult to remove this cap, unless special means to-that end be provided, I have also arranged to curve upward a portion of the cap as shown at 35. This has been accomplished by making two parallel slits in the upper layer of the part overlying disk 26 and stretching upward the part between the slits to form a curved loop, The same result might be obtained in other ways. The loop thus provided performs another function in that it may yield slightly to permit the upwardly extending flange to seat itself within the neck of the bottle, but being resilient, it nevertheless furnishes a spring brace to hold that flange in position, thereby giving a better though elastic hold to the cap than if there were no part 35 raised up between the vertical flange walls. The lip is covered and protected from dust, the cap is held on with an elastic grip and prevents spilling of the contents and the depression accommodates a small piece of ice to aid in keeping the contents, with no danger of the water from the melting of the ice, getting into the bottle, since the cap is sanitary and consequently necessarily nonabsorbent.

What ll claim and desire to secure by Letters-Patent, is:

A sanitary cap of non-absorbent. resilient material, adapted for use upon milk bottles,

and comprising a horizontal annular disk, as wide as the top of a milk bottle and adapted to extend to the outer line of the top 'of the bottle to be capped and to the inner line of said top, a downwardly extending wall in the form of a circular flange projecting vertically downward from the interior line of the horizontal disk portion and conforming in outline to the circular interior of the bottle neck to which it is to be applied, and a closing wall extending entirely across the space within said downwardly extending wall, closing said space and aiding in holding said downwardly extending wall in position, with an angle not greater than a right angle at the corner where the lower line of the downwardly extending wall joins the closing wall, some portion of said closing wall being ralsed I between the lines of the downwardly exname to this specification in the presence of tending wall, from the corner aforesaid two subscribing witnesses,' this 1st day of 10 thus constituting a spring holding (ievice, all August, 1911. arranged and combined substantia y as set 5 forth, whereby the cap may be sprung upon AARON SEGALL' the bottle top and held thereon by its own W1tnesses:

resilience. A. G. N. VERMILYA, In testimony whereof, I have signeti my CHARLES B. DAVIS.
