BOTTLE-STOPPER.

Specification of Letters Patent.

Patented Sept.. 7, 1920.

Application led February 12, 1920. Serial No. 358,012.

To all whom z't may concern:

Be it known that I, PAUL J HnN'rsonnL,

a citizen of the United States, and resident Vof Baltimore, Maryland, have invented certain new and useful Improvements in Bottle- Stoppers, of which the following is a specification.

ioI

My present invention relates to improvements in bottle Stoppers and is designed as an improvement upon the type' of bottle stopper disclosed in Letters Patent of the United States, granted to me on the 29th day of October 1918. i

The invention aims to provide .a stopper which shall be a unitary article and which may be easily and economically manufactured; and the invention includes the novel features of construction hereinafter described and particularly defined by the appended claim.

My invention is illustrated in the accompanying drawings in which- Figure l is a sectional view of a portion of a bottle illustrating the stopper applied thereinto in the position of pouring out the contents.

y iFig. 2 is a plan view `of a stopper embodying the invention.

Fig. 3 is a .transverse section of the same.

Fig. 3a is a similar view, but with the central portion ruptured and. lifted up to form the pouring opening.

Fig 4 is a plan viewl with the ruptured portion bent back into the position shown in Fi 1. l

' Figs. 5 and 6 are plan views of modified forms.

Referring by reference characters. to this drawing, the numeral 1, designates a milk bottle to which my improved stopper'2, is shown as applied, the rupturable portion being bent or deflected outwardly to form `a pouring flap or lip to serve as a guide to the liquid issuing through the opening formed by rupturing said central portion.

Heretofore it has been regarded as neces- -sary 'to make such Stoppers, having va central indenting it from opposite sides in the man'- ner hereinafter described, an integral flap may be provided which may be ruptured from. the body .of the stopper to provide a pouring opemng in such a manner that the fiap may be swung back into closing positlon in case a portion only of the contents of the bottle have .been removed.

The rupturable flap 2a is formed by cutting o r in'denting the stopper 2, from opposite sldes by cuts or indents which penetrate approximately half way through the thickness of the disk. The lines of out or indent areformed so as to inclose a portion of the desired shape to form the flap, and the lines are out of alinement with each other-that is, the indent or cut (a), in the upper surface of the disk is outside of, or farther removed from the center of the disk than Ais the out 0r indent a in the lower face. When therefore, one edge of the Hap forming y,portion is lifted `up and theflap is pulled upwardly, it is separated along the double lineas indicated in Fig. 3 leaving the disk with a rebate forming a shoulder a2 and the flap with a marginal flange a3, the shoulder forming a seat for the marginal flange when the flap is again closed.

To facilitate the beginning of the rupturing'of the flap I preferably extend or defiect the indent line a to form a tongue or projection af" per surface of the cap adjacent this tongue as indicated at ai to enable the finger nail to be inserted to start the rupturing operation.

As the flap is preferably not intended to be completely severed from the disk but only bent back as indicated in Figs. 1 and 4, I preferably arrange the indents. opposite the starting point to serve as a hinge, the lower indent ha'ving a straight portion a5 and the upper a straight portion a", though at this point the indent may be a mere crease or may be omitted altogether.

I f the central portion is to be removed entirely, both cuts or indents might be made completely circular as shown' in Fig. 5 at a7 and a8 and the tongue a" may be omitted if desired. y

In'Figs. 2 to 5 inclusive I have shown the indents as made by continuous cuts but the and cut out or recess the upindents might be by @way of separated notches or indentations or short disconnected cuts as indicated at a and al Fig; 6.

An opening 3`may be provided to acili- 5 tate the venting action in starting to pour. Having thus described my invention, what I elaim'isl Abottle stopper comprising an 'integral disk of fibrous material having its upper 10 and lower surface provided wlth 'substantially Vcircular weakening indentations, or cuts, the-line on the upper surface being arranged at a Vgreater distance from the center than'the lower2 .the indented line on the up- 'persurace-belng deiected .outward at one point to form a iinger tab, a portion of the material ofthe disk adjacent said tab portion being removed.

In testimony whereof, I afiix m si nature.
