SANITARY CAP REMovER Filed April 10, 1930 3nventor Eva Bay/warm omega Patented Sept. 1,; 1931 ,rniiiafl innei iann, b tenements;lemitsnvmm SANITARY car Rel eves a This invention relates to a sanitary cap remover particularly. adapted for the re,-
" I finoval; of the paper or cardboard ca'ps ordi- *nar-ily used onmilk bottlesge.
.The removal otthese paper closure: members orcaps ordinarily used. on milk bottles and similartypes of-containersis sometimes quite rdifiicult. The paper caps are usually forced under an overhanging lip onthe bottle or container to retain the caps in position.
They are also usually bowed slightly inwardly toward the contents of the bottle. This renders their removal most troublesome. If
aniat'tempt is,made-to' force the paper cap inwardly x toward the, bottle, pressure is put upon the liquid in the bottle and the liquid i quite'lt'requently splatters outwardly; It is a common practice for; housewives to puncture the 'paper caps; with a fork, ice pick, or
similar pointed implement in an attempt to remove -;the same. o vI-Iowejver, this operation must be most carefully done or otherwise the gliqiiid will :be forced 4 out of the bottle.
i Someadai'ries now useya special 'capwhich ii'sread-ilyremovable,having a wire forpulling the same out ofthe bottle, or a tab which amayiibebent upwardly togpull the {cap out.
These typesiof caps areexpensivej tomanufacture {and are troublesome to; insert since they;mustbe'positioned with thGWV -IIQYOI tab facing outwardly. I Moreover; it, frequently happens thatithe tabs; orl' wires become de- =,t ached fromt-he caps when an attempt is made to remove, the capsul r Itthe paper (caps aref'reinoved :from' the wbiottlesbypuncturing them with ja-fork or similar *implementthey have a hole through ithe'm and if the user; 1W1ShG'S to retain some -,tion but-the entrance; ofdust or other foreign 1 ef the milk Within the, bottle a for future, use,

it isj anobject ofthisinventionto provide i930.

Z Another object of this inventionis to provide a removingiimplement for the paper caps of milk bottles or vthe like, which is in the form ofa cup for: enclosing the entire end of-the milk'bottle'with a readily mov- Tablepart-thereon "for puncturing the cap,

- Another object of this'invention is to provide acap'remover'for use with milk bottles 'or the like, whichis simple and cheap to'man- 'ufacture, durablezin use, and thoroughly re- H Figure l-lSfi SGCtlOIlill view taken online '-1 1 of Figure 2.

Figures 4 andi5 are detailed views of' my to readily fit over the neck of a milk bottle or other container from which the cap is to be removed. The dependinggwall B -is per with the closed bottom 2; for the reception of a rotatableshaft l'journalled in the wall 3 anclhavi-ng retaining washers 5 thereon for maintaining the handle 'in position. This 1 shaft is prov-ided'with an external manually operable crank 6*forfopearting the same. The shaft v L hassec ured thereto for rotation therewith a "pointed h'ook member 7 which is 4 iT p ng"edevice ncludes a adapted to'p'er'forate through the paper cap :53 toremove'the same. 'Asseen in Figure 3, the
core .5 when secured to the shaft-4 will prevent misplacement of the parts. The entire mechanismis cheapto manpfacture andthoroughlye efiicient inits use; h It isoblieved that the operation of my de- 7 vice will be obvious from the above descripforated adjacent the junction oflsaid wall" tion. The cup-shaped member 1 is positioned over a bottle 18 or the like,- as shown inFigure 3', pressure on the cup-shaped mempapercap 17 is retained by the hook 7. The
paper cap 17 may now be ejected from the remover by a reverse'rotation' of theha-ndle 3, this reverse rotation withdrawing the hook 7 through the slot 16 of the spring When such withdrawal takes place the flower leaf.-
oft'he spring is further compressed and when the pointed end of the hook 7 is withdrawn from the opening in the'cap 17,the cap is forcibly ejected bythe spring out of the cupshapedmember '1. v i
' The cup 1 maybe used as a'cover for the milk bottle to prevent entrance" of foreign matter until all of the milk is used. When thus used as a cover fora milk bottle the fit between the neck of the bottle and the wall 3 nevertheless the entrance of foreign "matter into the bottle is effectively prevented and there is practically no circulation of :air in the bottle. It will be understood that in some cases I may-make the diameter of the casing such that the walls '3 will friotionally engage the neck of a milk bottle,' *whereby a practically air-tightseal willbe obtained. If desired, the cap 17 may be retained within the cup l'and be repeatedly put on 'and taken off from the bottle.
tion is desired, the handle '6 is not rotatedin a may remain associated therewith to function as a handle or'it maybe removed for use with another bottle. V v
The inventionmay be embodied in other If this opera as r reverse direction toeje'ct the cap 12 but re- 7 mains'in the position 'to which itwas'turned when the cap was punctured by the hook 7. Thus the cap 17 may-be accurately positioned 'liack onto thebottleand the cup member 1 specific forms WitllOLlt departing from the spirit or essential characteristics thereof.
The present embodiment is therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come Within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
What I claim and desire'to secure by United States Letters Patent is 1. A device for the removal of the paper cap of a milk bottle comprising a cup-shaped casing adapted to be positioned over the end of the bottle, a rotatable handle member journaled 'in' the depending Wall of said'casing,
a hook secured to and rotatable With said handle member adaptedto puncture through and retain the paper cap when said handle member is rotated in one direction and a, leaf spring bent upon itself, one portion of said leaf spring being bent around said handle member ithin the casing for retaining the leaf spring in position, the other end of said spring being slotted for the passage of said hook therethrough whereby the paper cap is ejected fromsaid casing after removal from the bottle by reverse rotation of said handle member. v I
2. The invention as defined in claim 1 wherein the upper rebent portion of said leaf spring is in surface engagement with the closed bottom of said c'asmg.
In testimony whereof I aflix my slgnature.
