BEMOVING DEVICE FOlR; THE CLOSURE-CAPS OF MILK-BOTTLES AND OTHER RECEP- TACLES.

Application filed January 26, 1915. Serial No. 4,569.

To all whom it may concern:

Be it known that I, THOMAS H. TAYLOR, a citizen of the United States of America, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Removin Devices for the Closure- Caps of Milk-Bott es and other Receptacles, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to a removing device for the closure caps of milk bottles and other receptacles and has for its object to provide means, in a manner as hereinafter set forth, for conveniently removing from the mouth ofa bottle or receptacle the 010- sure disk, said disk being what is generally termed a cap and is constructed of flexible material, preferably paper, and when mounted in position is seated within the mouth of a bottle or receptacle against a shoulder formed on the wall of the mouth.

Further objects of the invention are to provide a removing device for the closurers for milk bottles and other receptacles which is simple in its construction and arrangement, readily set up for the purpose of re movin the cap, strong, durable, preventing the spilling of the contents of the receptacle or bottle upon a person during the operation of removing the closure, efiicient in its use, and inexpensive.

With the foregoing and other objects in view the invention consists of the novel construction, combination and arrangement of parts as hereinafter more specifically described and illustrated in the accompanying drawings wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which come within the scope of the claim hereunto appended.

In the drawings wherein like reference characters denote corresponding parts throughout the several views:

Figure 1 is a vertical sectional view of a milk bottle provided with a closure cap and showing the adaptation therewith of a cap removing device in accordance with this invention.

Fig. 2 is a view similar to Fig. 1 with a pulling element shifted to a osition at right-angles to that as illustrate in Fig. 1.

Fig. 3 is a top plan view 'of a removing device.

Fig. 4: is a vertical sectional view, broken away, and

Fig. 5 an inverted plan illustrated in the modified form.

Referring to the drawings in detail 1 denotes the body portion of a milk bottle, 2 the mouth, 3 a shoulder formed on the wall of the mouth and 4 the closure cap for the mouth. The cap 4 is mounted against the shoulder 3 and is of ordinary form of paper disk which constitutes a closure for the mouth of the bottle.

The cap or closure removing device in accordance with this invention includes a guard 5, which is substantially dome-shaped in transverse section and is of such diameter to frictionally engage the periphery of the top of the body portion 1 of the bottle, when the guard is mounted thereon, and under such conditions provide a seal to prevent spilling removlng the bottle closure. The guard 5, centrally thereof, is formed with an upwardly projecting cylindrical extension 6, having its upper end closed by an integral disk 7 ,1 the latter is formed with .a centrally disposed opening 8, the wall of which forms a bearing for the shank of a combined cap piercing and pulling member to be presently referre to The cylindrical extension 6 provides a housing for a portion of the shank referred to, as well as an extended bearing therefor.

Extending down through the opening 8 is a combined cap piercing and pulling membeer and which consists of an elongated shank 9, terminating at its lower end in the base of a triangular shaped combined piercing and pulling element 10. Formed integral with the-shank 9 in proximity to the element 10 is an annular stop 11 and formed integral with the shank 9 exteriorly of the extension 6 is a head 12.

When using the device the guard 5 is mounted upon the top edge of the body porthrough the cap 4, as illustrated in Fig; 1, after which the shank 9 is given a alf turn and then pulled upward, and the element 10 will remove the cap 4 from within the mouth 2, the guard5 is then shifted from ofi the body portion'l and the cap 4 is Patented Mar. 5, 1918.

of the contents ofthe bottle when tion 1, and the element 10 is forced down carried therewith, owing to the position of the element 10.

The guard 5 prevents the spilling of the contents of the bottle when the cap 4 is removed from the mouth.

In the modified form shown in Figs. 4 and 5, the guard which is indicated by the reference character 13 is formed with a series of depending spaced lugs 14:, which engage the closure cap 15 and hold the latter on its seat. The combined cap piercing and pulling member illustrated in Figs. 1 and 5 consist of an elongated shank 16, having a reduced lower end 17 which terminates in a combined triangular-shaped piercing and pulling member 18. The shoulder 19 formed by reducing the lower end of the shank 16 provides a stop which performs the same function as the stop 11. The guard 13 has an upwardly projecting cylindrical extension 20 through which extends the shank 16, the latter snugly fits in the extension 20. The lugs 14, in connection with the base, of the cap piercing and pulling member, couple the cap to the guardwhereby the guard and cap can be removed from the bottle simultaneously.

What I claim is v Abottle cap removing device comprising a guard substantially convex intransverse section of a diameter to frictionally engage the periphery of a bottle at the mouth end thereof to form a seal, a triangular-shaped element capable of piercing the bottle cap and adapted on a half turn thereof to have its base provide means for removing the closure cap on the withdrawal of said element, a shank permanently extending through said guard and formed integral at its inner end with the base of said element centrally thereof, said guard having "means to provide an extended bearing for said shank, a head at the outer end of said shank and permanently arranged exteriorly of said bearing, and a plurality of spaced depending lugs integral with the inner face of the guard, surrounding said shank and capable of engaging the cap to hold it down during the piercing operation and in connection with the base of said element coupling the cap to the guard whereby the latter and the cap can be removed from the bottle simultaneously.

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

THOMAS H. TAYLOR.
