BOTTLE CLOSURE Filed April 2, 1955 INVENTOR K ORNEY r' Of Fi ure 1.

Patented May 4, 1937 UNITED STATES PATENT OFFICE BOTTLE CLOSURE John Henry Moir, Oakland, Calif.

Application April 2,

1 Claim.

Among the objects of the invention are to provide a bottle closure having against the entrance therethrough of bacteria into the bottle; to provide an improved closure,

having a pouring spout, for milk bottles which tended.

Figure 4 is a bottom plan view of the closure Figure is a perspective view mounted on a milk bottle and of the closure as with the pouring spout extended.

sertion in 'made of disk b or straight divergent The disky means of an A portion of the tab, adjacent its free end, is

Qremoved therefrom along the a as to provide a recess chordal lint i3 so I 4 which permits the user to insert his finger nail therein to facilitate movement oi the tab.

1935, Serial No. 14,339 (Cl. 215-51) Mounted on the back of the section 8 is a circular sheet I5 of relatively stiff material such as is provided with a central portion is outlined by a circular slit II, a pair of divergent scores l8 and a transverse slit l9. Each of the scores and slits mentioned above are disposed so that they lie in registry with the separated from the body of the sheet l5 by curved slits 2| which join the slit H, at one end thereof, and at the other end join the transverse slit IS. The purpose of the slit I9 is to permit separation of the portion Hi from the remainder of the sheet l5, when the spout is drawn through the aperture, for the reason that, in the absence of the slit, the portionof the sheet l5 adjacent the hinge of the spout would, due to being bent about a larger radius than the material of the disk, be liable to rupture.

All of the portions of the sheet l5 are adhesively secured to the section 8 with the exception of the wings 20 which maybe prevented from adhering thereto by the application, to the areas underlying the wings, of a coating 22 of paraifin.

It will thus be seen that when the tab portion 9 is moved forward the portion It will, due to its connection therewith,be carried through the aperture 23 created in the section 8 by the removal of the tab 9 therefrom. Simultaneously with the movement of the tab 9 the wings 20 will assume positions vertical to the plane of the portion l6, as shown in Figures 3 and 5. This is caused by the curved edges 24 of the wings bearing against the straight sides of the aperture 23 as they are drawn therethrough.

When the pouring spout is in the position indicated in Figure 5 the contents of the bottle may i be poured therefrom through the aperture 23 and, when it is desired to re-seal the bottle, the spout may be moved back to its normal position flush with the surface of the section 8 whereupon ,the aperture 23 will be closed.

In order to seal the closure against the entrance of bacteria or other contaminating matter into the bottle, it is proposed to provide a sealing sheet 25 of cellophane or other like material which may be adhesively attached to the top surface of the closure. It is preferable that the cellophane be attached by means of a tacky or nonhardening adhesive so that the sealing sheet may be removed and replaced, to re-seal the bottle, several times without the adhesive losing its gripping properties.

Having thus described the invention. it will be seen that an improved closure for bottles or the like has been provided which greatly facilitates the removal of the contents thereof, and at the 5 same time provides means for thoroughly sealing the bottle against the entrance thereinto of contaminating matter. In addition to these features the provision of a pouring spout, oi the proportions indicated, enables the user to pour the con- 10 tents from wide necked bottles in a concentrated stream with the result that the stream may be more readily controlled and losses due to spillage, in transferring the contents of the bottle to other containers, are greatly reduced.

15 What I claim is:

A bottle closure comprising a disk of relatively thick fibrous material having a slit therein defining an opening and a tab complemental to and disposed within said opening, said tab being integrally hinged to said disk at a side of said opening for free movement into and out of said opening so as to open and close the latter, a parent sheet of relatively thin stii'! material overlying one race of said disk, said parent sheet having therein a continuous slit defining a central portionseparable from the remainder of the sheet, said remainder of the sheet being adhesively attached to the disk and said central portion or the sheet comprising an area overlying and adhesively joined to said tab and free wing-shaped areas extending from opposite edges of said tab and overlying surfaces oi. said disk at each side of the opening thereof, and one portion of the continuous slit defining the separable central portion of said parent sheet being disposed immediately overlying the hinge of said tab.
