2' Claims 1,

My invention relates: to a. cap for milk. and;

other bottles and. may be used as desired for theonly caprequired'for covering a bottle. However, aprlme use for, my. bottlecapis vfor. capping amilk bottle after the ordinary disk. seal. cover, has been removed'from atmillsbottlee The general. custom tor the delivery of mills for householdtconsumption is to use-glass bottles,. the nozzles of whichareprovided with. an inward.

seat into which there ispressed. arfiat disk .01 pasteboard or other suitable material which is held in place by frictional contact within the nozzle.

The above indicated construction. leaves alittle circular. cavity above the disk into. which. there.

is opportunity for the accidental accumulation, of

foreign'matter, andttoavoidthisthere is provided different means for coveringthetop. of, theflbottle with an overriding hood made of a variety of materials, chiefly paper of some sort...

This outside hood. in most cases actslonly as a. protection against the entrance oflforeign matter. to the interior. of the bottle. in, which milk is storedand does notof itself formany realtight,

tight closure of the bottle against. leakage of the contents of the bottle whenv the. bottle, is

unset and that disk being the, only cover then of the bottle.

My cannot only providesifor a. tight closure of. the top of the bottle but it also provides a:

means whereby the diskcap, commonly used, may be engaged and, lifted. from the bottleusing my cap as the instrument for contactingand'lifting;

the diskcap from the bottle.

An object of my invention is to provide a cap, preferably of; metal or other materials which is sumciently stiff and et elasticin nature that it may be sprung onto the top of the bottle and automatically lock itself 'onthe bottle for a complete closure ofthe bottle.

Another object of the invention is to provide a cap of material having a series offspringflngers adapted to extend down on the outside of the bottle topand clamp my'cap into place and those spring fingers constructed in peculiarly desirable shapes;.n,ot;only for holding my cap in place but also to furnish means for using my cap as an instrumentv in removing another cap from the top off the bottle;

Another object of my invention is to provide a cap which furnishes the advantages above mentioned' together with an improved appearance and desirable shape for handling and applying inycap to bottles.

Reference will be had to the accompanying drawings in which Figure l is a perspective view of the top of a bottle with oneform of my cap applied thereto.

Figure 2 is a vertical section on line 2-2 of Figure 1.

Figure 3 is a perspective view indicating how my cap is preferably applied to the top of a bottle but it may be applied by vertical movement also.

Figure 4. is a perspective view indicating the method of using my cap as an instrument in removing an ordinary disk cap from the top of a bottle.

Figure 5 is a vertical section of the top of a bottle showing a modified form of the cap.

Figure 6 is a plan view of the top of my cap, asplaced on a bottle showing a modified form of" the clasping fingers of my cap.

Figure? is a modified form of one .of my clasping fingers.

In the drawings the simplest form of my cap is indicatedby'Figures 1 to 4' inclusive. This cap i provided with the upwardly embossed circular area A" offset at a shoulder 3 to stiffen the bearing seat portion 4 which contacts tightly the top-nose of nozzle 5';of the bottle 6. This bottle is substantially the standardmilk bottle for household delivery supply'having the, seat 'l'for the ordinary disk seal cap, one of which is indicated by B in Figure 4. The bottle 6 is provided with a reinforced ring nozzle 9.

The seat portion 4 is provided with a narrow flange ltladapted to fit snugly to the shape of thetop of the nozzle 5- of the bottle.

On the opposite sides of the flange [0 there extends downwardly the clasping fingers H and i2: Theseclaspingfingers are of spring character and claspsnugly to the portion 9 of the nozzle. Each of the clasps H and I2 are provided with small holes l3 which may be used for hanging the cap on a nail or a hook for supporting the cap when it is not in use on a bottle.

In the ordinary use of my cap as in common commercial practice, the milk will be supplied to the user beingcapped only by a common pasteboard cap indicated by 8 in Figure 4, and mounted in place on the seat I of Figure 2.

The first act of the user in drawing some milk from the bottle is to remove the disk seal cap 8. Many of these disk caps are provided with a wire staple hook on one side thereof, or a portion of the cap has been cut asunder to provide a small lip section M, see Figure 4. It is a bit troublesome to lift out this disk with the ordinary fingers, even though the disk may be provided with a Wire staple or the lip Hi.

I provide my clasping finger l l with an extend the points l5 as shown for the clasping fingers ll.

Yet withal the ends of these fingers l2 may be used to engage the lip M or a wire staple into the disk 8.

A modified form of my fingers l l and I2 is indicated in Figures 6 and 7. This modified form is provided with the clasp body 18, see Figures 6 and '7, which are provided not only with the extending point i5 but is also provided with the outwardly curled over edges ll which act as guides in shoving my cap transversely across the top of the bottle in placing the cap on the bottle. The sheet material of the clasp body It onthe edge opposite the curved edges ll is recessed in an edgewise manner thereby providing a hook shaped projection Hi. This hook shaped projection [8 has its point directed toward the cap and may be used as desired in place of the extending point IS in lifting a disk cap 8 from the top of a milk bottle.

In removing a conventional milk bottle cap an advantage results from using the hook-shaped projection [8 of the ear IS in cooperation with the central downwardly extending point l5, because, when the hook lfi has been inserted into the flap or lip M of the bottle cap, as indicated in Fig. 7, said point l5 may then be indented into the cap and used as a fulcrum to remove the cap by a prying-01f movement, rather than by bodily withdrawing the latter in such a sudden manner as would be likely to cause an out-splash of milk. When it is so used, the widened part of the ear l6 superjacent to the point l5 provides shoulders which prevent too deep a penetration of the point l5 into the cap 8 and assist in prying off the latter. The out-curled parts 51' are also useful as finger-holds to assist the operator in lifting the metallic cap from the bottle.

In the normal use of my cap it will be slid transversely across the top of the bottle as indicated by Figure 3 by moving toward the left the cap shown at the right of Figure 3 and sliding it transversely across the top of the bottle, in which movement the flange Ii] of the cap slides over the top 5 of the nozzle and the fingers ll and I2 will spring outside of the portion 9 of the bottle, and when the movement is complete, bringing the cap concentric with the nozzle of the bottle and the spring action of the fingers will cause the cap to move down snugly on to the top of the nozzle 5 making a complete seal of my cap to the bottle.

However, the cap may be mounted directly over the top of the bottle and pressed vertically downward causing the spring fingers to snap into place and hold the cap to the bottle.

The modified form of the cap as shown in Figure 5 is provided with an inwardly embossed seat 19 which is provided with an overlapping flange 20 on the inside of which is mounted a ring 2| of a gasket character. The lower skirt 22 of the overlapping flange 20 has been slitted up part way in sections to permit a springing actionof the skirt in clamping the outside nozzle of the bottle as this cap is applied to the bottle.

For convenience in handling this cap of Figure 5, there is provided the hand hold knob 23.

As and when desired the cap as shown by Figure 5 may be provided with a pointed clasping "finger 24 as shown in dotted lines in Figure 5.

This pointed finger 24 will be used in prying up a disk cap as indicated in Figure 4.

What I claim is:

1. In a cap of the class described, a central area surrounded by a circular seat portion, a circularflange extending downwardly from the outer edge of said seat portion, two diametrically opposite spring ears each having side edges, said ears extending downwardly from said flange, at least one of said ears having in one of its side edges an arcuate recess which produces a hook with a point suited to hooking onto the fingerhold flap of a'conventional milk bottle cap. said point being directed toward the aforesaid circular flange, said ear having also a central downwardly directed point portion to indent or puncture a conventional milk bottle cap, the latter point portion affording an anchored fulcrum point for use in prying off said conventional cap when the aforesaid hook is applied under the finger-hold flap thereof, said ear which carries said downwardly directed point portion being widened superjacent to said downwardly directed point portion thus affording stop shoulders which prevent more than a slight penetration of the cap by the latter point portion when used as a fulcrum, as aforesaid.

2. In a cap of the class described, a central area surrounded by a circular seat portion, a circular flange extending downwardly from the outer edge of said seat portion, two diametrically opposite spring ears each having side edges, said ears extending downwardly from said flange, at least one of said ears having in one of its side edges an arcuate recess which produces a hook with a point suited to hooking onto the fingerhold flap of a conventional milk bottle cap, said point being directed toward the aforesaid circular flange, said ear having also a central downwardly directed point portion to indent or puncture a conventional milk bottle cap, the latter point portion affording an anchored fulcrum point for use in prying off said conventional cap when the aforesaid hook is applied under the finger-hold flap thereof, said ear which carries said downwardly directed point portion being widened superjacent to said downwardly directed point portion thus affording stop shoulders which prevent.

more than a slight penetration of the cap by the latter point portion when used as a fulcrum, as aforesaid, that edge portion of the aforesaid capremoving ear which is opposite to its cap-removing hook portion being outwardly curled over in relation to the center of the first recited cap, the diametrically opposite ear having a correspondingly outwardly curled over portion, so that said curled ear portions cooperate when engaged with opposite sides of the mouth portion of the milk bottle to guide the cap toward its applied position.
