To all 'whom it mafz/ concern.' n

Be it known that I, Lim WnarAMs, a citizen 'of the United States, residing at Texarkana, in the county ofBowie and State of Tekas, have invented 'certain new and useful Improvements in Bottle-Closures, of which the followingv is a specification.

Thisl invention is a bottle cap or closure more particularly adapted for use in connection with milk bottles wherein the cap may be easily removed and replaced without ldanger of breaking and is resiliently held without accidental displacement.

@ne object of the invention is to provide a bottle cap kor closure made of glass 'r porcelain and formed with an overhanging iiange adapted to 'coperate with the lips of the mouth of a bottle and is provided with a knob mounted 'on a shank for removing and replacing the cap.

Another object ofthe invention is to provide a cap or closure having a shank and knob with a resilient retaining member formed of wire adapted to coperat'e with the shank and knob and with the thickened lips of the mouth of a bottle.

A-further object of the invention' is to provide 'a proper closure that will tend* to keep the lips of the mouth ofa bottle in clean and sanitary condition, one .that will be held on the bottle against accidental displacement, one that will be relatively cheap to manufacture, andnone that may be easily cleansed and sterilized for use a second and more times. y l d, v

Broadly stated the invention comprises a closure including a circular 'cap having a disk-like body portion adapted to 4.seat within an annular groove formed adjacent the mouth `of a bottle, said disk having a tiange projecting therefrom and of greater diameter than the disk portion, said flange being adapted to engage with the pouring edge of the lips when the disk portion is seated in the groove, said cap being provided centrally with an annular recess or groove from the center of which there projects upward a shank carrying a knob at its outer end, said groove being concentric to the periphery of the fiange, and a resilient holding means formed of wire having a substantially U- shape and consisting of two wires spaced apart and centrally7 of the transverse portion, said wires being curved and adapted to engage with the shank when the wires are separated to pass over the knob, the vertical portion kof the retaining means being curved at their free ends tel approz'imate the 4curve of the thickened lip of a bottle and also to provide linger engaging portions to permit the quick removal from said bottle.

Une practical form of construction and assembly will be described and illustrated in the accompanying drawings, in 'which- Figure 1 is a detail sectional view through the bottle and cap but showing the wire retaining means and the knob in elevation,

gig. 2 is a top plan view of the assembly, an

Fig. 3 is an 'end elevation of the cap and the wire retaining means detached from a o bottle.

In the preferred: embodiment about to be described the neck 6 of a milk bottle is shown in 'section inFig. 1. The mouth of this bottle is provided with a thickened lip indicated at 6 and interiorly and concentric with the lip is a shouldered groove 7 This groove is concentric to the passage 8 in the neck of the bottle. The shouldered groove 7 connects with the pouring edge 9 with a very slightly rounded corner as more pai'- ticularly shown in Fig. 1.V 4

The bottle closure cmpri'ses a circular cap A that has a disk-like body portion 10 that is adapted to seat and be engaged with the shouldered groove 7 so as to effect a-closure of the passage 8. Connected with the disklike portions 10 is a flange 11 that is of greater diameter than the disk-portion 10. This flange, where it 'joins the disk-like portion 10, forms a shoulder 12 that may be slightly rounded to conform to the rounded corner 9 so as to provide for a more effectual sealing of the contents 0f the bottle.

The flange 11 has one face 13 adapted to rest upon the upper end 14 of the lip portion 6 and adjacent the pouring edge orcorner 9. The upper surface 15 of the flange is provided centrally with an annular recess 16 that is of such depth that it partly lies within the body portion 10. Centrally of this recess 16 there arises a shank 17 carrying at its outer end a knob or button 18.v

This knob or button 18 will provide a linger hold when it is desired to remove the cap A from the mouth of a bottle. The recess 16 will allow the tips of the ngers and thumb to readily grasp the knob 18.

As shown the cap A may be formed of material similar to that from which the bottle is formed but it may be formed of any suitable material such as porcelain if desired.

Any one of the substances employed in the ceramic art may be used. It will be noticed that the under surface 19 is substantially parallel to the upper surface 15.

To retain the cap A in position upon 'the bottle a resilient retaining means generally indicated at B is employed. This retaining means preferably comprises an endless piece of wire and formed in such a manner that when bent upon itself it forms the two spaced and parallel portions indicated at C and D. The portions C and D are complemental and are preferably formed to have approximately a U-shape. The transverse portions indicated at 20 and 21 lie substantially parallel again the surface 15 of the cap and in close engagement therewith. Intermediate the ends of this transverse portion the wires are bent outward slightly as at 22 and 23 to provide a loop that is adapted to engage with the shank 17.

As the means is formed of resilient material the members C and D may be sprung apart so that they will pass over the knob V18 at the curved portions 22 and 23 with very little trouble. When the separating force is removed the two members C and D will springl together and partially encircle the shank 17.

The vertical portion of retaining means are similarly formed. Each vertical yportion comprises a straight section 24 that makes an approximately right angle bend to the transverse portion and thus lies in close contact with the iiange 11. Extending from this straight section 24C there is a curved portion 25 that bends inward and is adapted to more or less conformto the curve of the thickened lip 6 as shown more particularly in Fig. 1.

The extreme lower end 26 is bent in a reverse manner and outward away from the neck 5 lof the bottle to provide a finger hold so that when the closure is placed on a bottle as shown in Fig. 1 the finger may be in- Serted at this point and the closure readily removed from engagement.

From the above description it will be noted that the cap being formed of material such as glass that it may be readily cleansed and sterilized for use a second and more times. It will be noted that the surfaces that come in contact with the contents of the bottle and with the pouring edge are surfaces that may be readily washed. As will be seen from Fig. 1 when the closure is in position that the pouring edge is effectually prevented from contacting with any foreign surfaces so that when the contents are poured they pass over a clean pouring edge.

When it is desired to remove the cap from the bottle the linger may be inserted under the end 26 which will force the vertical section 24 outward so that the curved portion 25 will pass freely over the thickened lip 6. The closure may be then removed entirely from the bottle. When it is desired to remove the cap from the retaining means the portions C and D are sprung apart a sufficient distance so that the knob 18 will pass between the curved portions 22 and 23. A reverse operation will take, place when it is desired to insert a new cap.

A bottle closure comprising a disk having a recess formed in the upper surface, a shank extending upwardly from the recess and having a knob on the upper end thereof, the under side of the knob being flat, and means .for securing the closure to a bottle, said means comprising a substantially inverted U-shaped metal clip formed of a single piece of wire, the upper cross bar of the clip lying flat upon the top of the disk and engaged by the lower surface of the knob, the shank being of such length as to leave a space between the upper surface of the disk and under surface of the knob equal to the thickness of the wire clip.

In testimony whereof I affix my signature in presence of two witnesses.

LEE WILLIAMS.
