TEICHMANN BOTTLE CLOSURE Filed Feb. 7, 1953 rnlnlilvllllllll Vnilrlitlliilll INVENTOR l atentecl Sept. 4, i934 UNITEDF'ST-VAJ TESII- ATENToFFIC J 1,972,542 BOTTLE CLOSURE Henry' l fiiil eic'hniaxin, washingtomla. l Application February 7, 1933,' S erial No. 655,545 4 Claims. (01. 215 55) The invention relates "to a closure for bottles,

particularly bottles in which ginger ale and other beverages are sold. A-bottle of the type to which I refer includes a long neck, terminating in a mouth from which the beverage or other contained liquid is discharged, andmy object is to provide a bottle closure which may be secured in place, without the aid of grooves, ridges, or lugs at or adjacent the mouth of the bottle. In accordance with my invention the upper neck portion of the bottle may be. absolutely smooth, presenting none of the usual grooves or other surface irregularities in-which dust and other impurities may collect. Thus, the bottle is moresanitary in service. 1

It is further the object of my invention to providea bottle closure which may be removed-by hand, that is, without the need of a bottle opener. Additionally, I-aimto provide a closure that may be .removed and replacedat will, so. that, after-- the. bottle has been initially opened and partly emptied, the remaininglcontents of the bottle may atall timesbeefiectively sealed, and'themouth of the bottle kept clean. x

The invention is illustrated in ing drawing, in which Fig. I, is a fragmentary'view of a long-necked-bottle,showing in vertical section the closure of my invention securedin'position of service over the mouth of the bottle Fig.- II is a view in'p'lan fromabove of the closure.

The bottle closure comprises twoprincipal:partst-;,

a-cap and a sleeve-, and Figs. III; IV, andVare.

views in cross-section, illustrating the. various forms in which the sleeve may be made. 1 Fig. VI is a view'in vertical sectionof the cap; Fig.

additionallyshows (in side elevation) a gasket:

member and stopper which normally are assembledwith and form apart of the cap' in serv-'-.

ice: iFig. VII a 'view in bottom plan of the cap without the gasket and'stopper. Fig. 'VIII 'is a View. in plan from above, and a. view partly in side elevation. and partly invertical section, .offacap of modified structure. Fig. IX shows" two similar [views of a cap embodying "still other: modi:-.

fications. And Fig. X is a fragmentary view of a bottle, showing. (partly in' side elevation and. partly in vertical section) the cap structure :of: Fig. IX in position'of service upon the mouth of 1 the bottle.

The bottle closure comprises a cup shaped cap H 7 v I of sheet steel or sheet aluminum of from Nos. 28

1 which ordinarily will be fashioned from sheet rwithin'itheimouth of the bottle, while the side wall theaccompany of the cap overliesand snugly engages the outer, surface 30f the bottle neck. 1 The stopper 2 may be made of cork, rubber, or other suitable yielding material, depending upon the nature of the liquid to bestored within the bottle, and adisk or gasket 4, conveniently of such material, issecured in position against the top of thecap. As will be observed in Fig. I, the stopper plugsthe mouth'and 'snuglyengages the throat surface (5) of the bottle; the gasket 4 rests snugly against the rim or lip 6 of thebottle; and, as mentioned, the side wallof the cap snugly engages the outer surface 3 of the neck. Thus, substantially all of the terminal surfaces of the bottle neck are engaged by thecap, anda hermetic sealing of .the bottle is insured. In accordance with my aim, all of such terminal surfaces are-smooth, affording no indentations'in which liquidfrom within. or impurities from without the bottle may accumulate, as in the hands of the consumer the cap is removedfrom and replacedin position of closure upon the bottle. 1

I provide particularly eflective means for se- A curing the stopper and gasket in assembly with the cap 1. Such meanscomprise an elongate clip 10.- 'Advantageously, the clip 10 is formed of a strip of sheet metal bent double, providing. atwo-legged stem which is rectangular incrosssection-,.cf. Fig. VII. .Manifestly, the two legs a and b are. united at oneend of the clip' and separableat its otherjend. The clip at the bend;

spot-welded or otherwise secured at the top of .the cap; The gasket and stopper are each provided with a passage 11 corresponding in cross-section. with the clip; the gasket and stopper are fitted upon the clip, and the ends of the legs aiandb are bent outward, underlying the bottom .of' the stopper, and effectively securing thezparts in assembly-(cf. Fig. I) i a .A sleeve v '7 is -pre ssed into snug surface-tosurface engagementwith the cap l and theouter surface 3a.,of the bottle neck immediately below the cap. {The sleeve 7 constitutes an outerorf secondar'ylseal for the mouth of. the bottle. The sleeve ordinarily is a preformed tube which is 100 pressedandfcrimped into position of .service upon the bottle neck It is a sleeve of substantial material, as distinguished from the metal foil covers commonly placed over the capped ends of beverage bottlesi-indeed, the sleeve made 105 to '34 U. -S."Stand ardgauge. Such sheet metal is fashioned into a tube, having the meeting edges ofthe sheet united in a lap joint M, as shown 1 inFig. III; Alternatively; the, meeting edges of the sheet may be united in a ship-joint 7b, as indicated in Fig. IV. For reasons presently to be described the sleeve may be fashioned of the corrugated sheet shown in Fig. V, and the meeting edges of the sheet may be lapped, so that several corrugations are nested together, as shown at 70. Additionally, I contemplate that the sleeve may be cut to required length from extruded metal tubing :WhOS8"W&l1:thlCkIlSSSSxCOIe' 10 responds to" the sheet gauges mentioned. I

The side wallof the cap 1 is provided with a raised portion which in assembly is snugly engaged by the outer sleeve '7. In efiect the cap-sv and sleeve are interlocked, so that the consumermay grasp the outer sleeve and work the clo sure free from the bottle. I show thexraised portion in the cap wall as comprising an annular or circumferential bead 12,"a"ndadvantageously" such bead is provided by flaring the peripheral;: rim of the cap 1, as shown in Fig. VI. In Fig.

I it will be perceived how in assembly the: outer."- sleeve 7' interlockswith the bead "12; .it will be observed that the outer #sleeve'? is elongate,.and it will be understood that insposition upon:the, bottle the closure deviceconstitutesineffect a sturdy cylinder which the-consumer may readily grasp. 'I'o open the bottle, thezbottle is heldwin" theleft hand and the closure tightlyigrasped in the right hand, andthe-required forcetis apgcvplied to withdraw the cap and sleeve together from the bottle. The external shape of theolosure, together with itssturdiness, readily admitsv of the application of. .the'iorcerequired to open-'- thebottle, sothat in the hands of the "userzthei bottle may be opened without theaidof-a bottleopeningetooli The removalis more' readily -effected if the device is rotated slowly, before and. while it is being pulled fromthebottle;

It is desirable that the several elements: of the 40 :clo'sure besecured one to another: against rela-e:

tive rotation,- so. thatirotation of. thessleeve 'will.

be accompanied by the rotation of fall; the. clo-.; sure elements. Thus, the. .usuall-adhesioniexisting between the stopper.xand:;bottlezmay' 'bezw -:broken, and theremovalbfthe device facilitated.

To this. end I form the ;..clip- 10 rectangular in? cross-section, and the flatsides' oh the aclipgiri: lying within the correspondingly"shapeda'passages l1 in:the'stopper-2 and thewasher grinsure'ethat 0 sthe; cap, stopper, and. washer are secure :against: relative rotation; Thelegs' afbiof the. clip:10: may, as in Fig; I they areshown, be turnedupii. at. theirtipsc, and pressed-laterally into the 1 body material of -the stopper; to provide-aaddie; =itional means for preventing :rotary Smovementrofi; the stopper within the cap. Ini'makingiai'pro- 1 vision for union of the cap and sleeve, I adva;r 1---- tageously interrupt the peripheral '-bead--on'= the cap at one or more-points13 (cf. Fig.- IX):- eo' 'lhe bead fot interrupted continuity may be formed by rolling the-metal bordering therim" of the cap" (1a)" over and" upon small: wire 14,'. which; .wire, too, may be' interrupted in its extent at the points. 13," 13; "Thus, the. cap structure is rendered 'niore. sturdy1for the service to which itf'is put." WhenjtheOllteI 'f" sleeve.note the sleeve-7min FighX is. pressed '1 intoposition over the cap .andnecklof the .bot-.- tle, the body metal of the sleeve .closely .enga'ges' the bead .15.and nests in theintervals or points.

that will press the outer sleeve into such position of assembly upon the bottle neck.

As indicated in Fig. V, the outer sleeve may be corrugated lengthwise, to render the device in service more secure in the hands of a person opening the bottle. It is contemplated that the corrugations shall in most cases extend only part way of the length of the sleeve, the opposite end regions. of'the sleeve beingrrsmootht'forsnug engagement withthe cap 1 and bottle neck,respectively, while the medial portion of the sleeve is corrugated in the manner mentioned.

1 When the bottle is opened and only part of its contents. are withdrawn, the closure device may be'replaced in position of service, thus constitutingrattemporaryrstopper after its prime function as a bottle sealhasbeen completed. In such use as atemporarystopper, the outer sleeve of the devicer' mayg'be removed and the cap structure 1, 2, 4) used alone, or'the sleeve and cap structure may beusedtogether as a'temporarystopper upon-thebottle."

In= Fig? VIII, I show a modified cap: structure 1b, in which thestopper is provided by shaping in the top wall of the cap' a hollow cylindrical i stud 2a Conveniently,-a:1ining 4c of: compressible material, such as cork,- is:applied to the topwall': and stud within thecap. Ma'nifestly, the caplb may be used exactly as the cap structurel, 2, 4 is used in combin'atio'n with the outer 1 sealing sleeve .7, to provide the closure ofmy invention; Within the boss 2azI securea member 2c,-and (as may .be perceived in. FigQVIIIl the: member 1 may bear numbers; letters,*- or-:other data for designating the bottled liquid. It will be further observed in-Fig. VIII .thatuthe boss 2a-and its cork covering'4c liewithin' thea'im of thecap; indeed,-the:stopper 2 .of: the flrst-described structure terminates within or above :the :rim, :so that; when the cap is placed-aside, the stopper does not come in contact withcdust: or other impurities.
