SANETARY BUTTLE-STUFPER.

Specification of Letters Patent.

Application nled May 22, 1916. Serial No. 99,039.

T0 all whom it Amay concern.'

Be it known that il, Roscoe P. BUrFiNe- TON, a citizen ot' the United States, residing at Baltimore city, State ot Maryland, have invented certain new and useful llmprove-` ments in Sanitary Bottle-Stoppers, oit which the following is a' specification.

rll`his invention relates to bottle seals, and more particularly to an improvement in the seal shown in my Patent No. 1160571, dated November 11S, 1915.

The object ot' the invention is to provide a bottle seal which is entirely devoid ot metal parts, and which is provided with an outlet to permit the contents of the bottle to be poured out withoutl removing the seal. rl`he outlet is provided with a closure, and these parts are so arranged that the contelits of the bottle do not come in contact with any portion of the seal which may have been touched by the persons fingers, thusremoving all danger ot contamination.

'l` he invention also has for its object to simplify the device disclosed in the patent referred to.

ln order that the invention may be better understood, reference is had to the accompanying drawing in which- Figure 1 is a plan view of the device; Fig.

2 is a cross-section thereof in position on the' bottle; Fig. 3 is a section showing the bottle inverted to pour out its contents; Fig. 4 is a plan view of the sealing disk, and Fig. 5 is a plan view of a closure.

ln carrying out the invention, there is pro vided a circular disk 6 of pasteboard or similar material which is dimensioned to tit tightly in the mouth of the bottle 7, the same having the usual internal shoulder 8 on which the disk seats. The disk 6 has a central opening 9 providing an outlet through which the contents of the bottle may be discharged as shown in Fig. 3. rll`he area of the outlet 9 is such that it may also serve as a vent, thus obvi ating the necessity of providing the disk with an additional opening for this purpose.

Un top of the disk 6 is mounted a closure for the outlet opening 9, this closure being a disk 10 having the same contour as the disk 6. 0d to one side of the center ot the disk 10 is a creaseshown by the dotted line 11. This crease extends entirely across the disk and divides the same into two segments. The smaller one 12 of these segments is permanently fixed to the disk ti below the outlet opening by being pasted thereon in, any suitable inanner, forming a sealed joint between the two disks at the edge ot' the pouring opening, leaving the larger segment 13 tree of the disk@ and serving as a flap to cover the opening 9. The crease 11 forms a closed hinge connection `between the segments to allow the larger segment which forms the closing flap for the opening 9 to be swung open and closed, and to facilitate the operai tion of the flap, the saine is prdvided with av small tab 14 extending from the edge of the flap, the tab being integral with the flap and being toldable over oii top thereof as shown in Figs. 1 and 2. To facilitate the folding of the tab, there is made a transverse crease in the paper at the, junction of the tab and the body ot the flap, this crease being shown by the dotted line 15 in Fig. 5. The tab also has a. central longitudinal crease 1G so that it may be folded on this line when it is grasped to operate theiiap.

-When the device is in sealing position, the disk 6, with the disk 10 on top thereof and closing the opening 9, are in the bottle mouth as shown in Fig. 2, the tab 1t being also folded down, so that there -is nothing pro- ]ecting from the bottle mouth. To pour out the contents of the bottle, the tab 14 is grasped, and the Hap 13 is pulled outward to uncover the opening 9, whereupon the bottle may be tilted to pour out its contents as shown in Fig. 3. The bottle will be so positioned that the iap hangs down, so that it now serves as a pouring spout or lip. 1t will also be noted that the liquid .comes in contact with the under side of the flap, and the tab is behind the Hap, in view ot which it will be evident that there is no danger of the liquid becoming contaminated by coming in contact with any portion ot the device which may have been handled.

rlhe disk 10 will be made ot paradned paper of sufficient thickness to serve the purpose for which it is designed. is the smaller segment 12 is permanently ired to the dfisk 6, the crease 11 forms a substantial hinge joint for the fla-p formed by the larger segment 13, and said Hap, when swung down to cover the opening 9, seats tightly in the bottle mouth and thus terms an efficient closure preventing dust, dirt, insects, etc., from getting into the bottle. No metallic parts are necessary, the entire device being formed ot paper or pasteboard. rlhe structure is also simple and inexpensive and the cost et the Patented Dee.. 12, 19119..

device will be but slightly greater than that of an ordinary sealing cap such as used on milk bottles.

I claim: A bottle seal, comprising a disk provided with a pouring opening having a 'relatively l wide pouring edge, and a combined cover and pouring lip for said disk and opening, said cover and pouring lip having a closed 10 hinged joint formed across the same and a closed connection with said disk, both said closed hinged joint and closed connection with the disk being positioned adjacent said Wide pouring edge.

In testimony whereof I affix my signature 15
