ZBOTTLE- CLOSURE.

/ i To all whom it may concern:

Be it known that 1, Louis HUn'rnwonn, a

on citizen of the United Statds, and a resident of the borough of Br'ookl city and State 5 of New York, have invented certain Improvements in Bottle-Closures, of which the following is a specification.

This inventionjrelatcs to certain improvenients in bottle closures, and more particularly in that-class of such devices which are especially designed and adapted for employment in connection with bottles provided iii-with fillets or lips extended around their months, as milk bottles, for example, and the object 015 the invention is to rovide a device of this general character or a simple and comparatively inexpensive nature, and '"fof a novel and improved construction, which shall be capable of convenient application to and removal from the bottle in connection with which it is'em-ployed, and whichshall I serve, when in plac'euponthe bottle, to effectively seal the same against the accidental discharge of its contents. H The invention consists in C91'tillIl 'Il0V6l featnresof the construction, and combinations and arrangements of the several partsot the improved bottle closure, whereby certain important advantages are attained, and the device is rendered simpler, less expensive and otherwise better adapted and more convenient fol-"use, all as will be'hcri-iii'iafter fully set forth.

The novel features of the invention will be carefullydefined in the claim." I i In the accompanying drawings which serve to illustrate my invention Figurel is a fragmentary view showing the neck ortion of a milk bottle provided with a c osure constructed according to'my invention Fig. 2 is a top view of the improved closure constructed as shown in Fi 1 Fig. 3 is an enlarged sectional. view ta en axially through the bottleneck and closure-and illustrating and Fig. '4 is a view illustrating the forma tion which will be hereinafter expla1nedtion of the blanks from which the metallic adopted for milk bottles and the like, al-

thoughit will be evident that my improvements-are capable of embodiment in closures for other bottles with good results. The device is, however, especially desirable for use upon milk bottles, as will be hereinafter explained.

The bottle neck 1 is provided with anannular outwardly directed fillet or lip 2 extended around its mouth, the upper surface thereof being rounded or curved 1n profile, as indicated at 3, and the lower partof said lip or filletibeing curved or sloped inwardly toward its junction with the wall of the neck portion of the bottle, so as to produce upon said neck a curved outwardly directed shoulder 4, which projects therefrom in annular form and overhangs the lower part of the bottle neck in a well known way.

5 represents the inner member-of my improved closure, which may be conveniently formed "from paper of suitable compressi-' bility and thickness, and may be treated to render it moisture proof. This member is of such diameter that its marginal portions are adapted to be lapped over the rounded upper surface of the bottle lip or fillet, as shown at 7 in Fig. 3, and to be extended downin cylindrical arrangementas shown perimetral surface 2 of the lip or fillet 2. As herein shown, the central portion 6 of this mcmberfi, which is positioned, during use, directly above the bottle mouth to close the same, is slightly depressed below the marginal portions 7 which contact upon the rounded upper surface 3 of the li or fillet.

This inner member 5 will pre erably'bc pressed to substantially the form shown prior to its application tothe bottle so as surface 0 vthe bottle, lip or fillet. When formed from paper or similar substance, the compressible nature of such material' will permit the member to accommodate irreguarities in the surface'of the lip or fillet and thereby insure a tight joint. between the parts, The member 5 may also be formed from molded material, if this be desirable.

10 represents thevouter' metallic member of-my improved closure, the same being or annular piece of thin sheet metal of a diameter adapted -to' fit snugly outside the inner compressible member 5,' and being formed witha centralaperture'12 adapted herein shown as made in the form of aring vention.

to overlie the bottle mouth as clearly shown in Figs. 2 and 3, and whereat the central .shown at- 12 in Fig. 2, for example, printed or otherwise produced upon the top surface of the inner member 5, will be clearly Visible? at the mouth of the bottle .when the closure is in position thereon. This construction vpermits ofv conveniently printing any de the inner member sirable matter upon the compressible inner member. As herein shown, the legend 12 comprises characters representing the date of bottling the milk, so thatthe purchaser mayconveniently inform himself as to the character of, the contents- The depression of the central part of the inner member. as shown at 6, insures accurate contact of the m arginal portions 7 with the top surface 3 of the bottle lip or fillet, but such depression is not essential to my indepressed, the inner edge portion of the annular outer member 10, around the margin of the central .opening 12 thereof may also be depressed, as shown at letin Fig. 3, so as toserve to hold the marginal parts 7 of; the; inner member in accurate contact-- with the bottle lip or fillet, and also lessen the liability of the improved closure being accidentally detached from the engagement of obstructions beneath said inner edge portion of the outer member. Beyond the said inner edge portion 14, the

annular member is given a curved formationin cross section, as shown at 11 so as to conform to that curved marginal part '7 of v 5 whiehfits upon the rounded top surface 3 of the lip or fillet of the bottle, whereby it will be seen that this part 11 of the outer member serves to hold the inner compressible me1nber.in position for accurate contact upon the bottle lip as clearly shown in Fig. 3.

The outer marginal portion of the annular band or member 10 is made in cylindrical form, as shown at 1-5,-and affords an annular flange pendent around the outer part of said outer member and conforming to and adapted to fit snugly against the outer surface'of the cylindrical .pendent part8 of the compressible inner member in such a manner as toreinforce the same around its entire circumference and compel accurate contact of said inner member around the peripheral surface 2 of j the bottle lip or fillet 2. Y

At suitableintervals around the loweredge of the pendent outer flange portion 15, of the outer member 10 are produced downwardly directed. retaining pro'ections or tongues 1,6, 16, the lower ends 0 which are.

directed at inwardinclinations to the sides of the bottle neck, and the lower extremities \Vhere said inner member is sotion' of metal.

the bottle by The construction ofthe device with the 7 of which approach each other, as shown in the drawings, so as to be adapted, when the ji'actions ontongues 16 integrally produced thereon will permit the device to bereadily snapped upon or removed from thebottle without deformation of said retaining tongues, the inwardly inclined lower-ends of said tongues having spring engagement beneath the bottle lip or fillet when the clo sure is in place upon the bottle, so as to securely retain the same in position. As shown herein, there are four of these tongues 16 uponmember 10, the same being spaced at comparatively. wide intervals so as to permit economy in manufacture. When so formed, the metal parts from which the members are produced may'be blanked out from the, sheet in the arrangement indicated in Fig. 4, the tongues of one memberfitting in the spaces between the tongues of other members, as shown at 16, whereby a, ma-- terial economy is attained 1n the consump inner and outer members having the pend entmarginal flanges 8 and 15 contacting and the outer member having the inturned retaining tongues 16, insures a-secure connection between the parts and prevents their separation, thereby permitting the members to be connected in n'lanufacture, so as to be capable of being more conveniently handled during printing of the inner member or application of the date thereto, and during application of the closures to the bottles for use. of the innermember with the outer when the bottle is opened, and serves to retain the inner member within the outer member so that the closure may be returned to the bottle after removal therefrom. The construction of the improved closure with the cylindrical flange, pendent around its outer part also insures a tight joint between such mar inal flange and the peripheral surface 2 of the bottle'lip or fillet 2, so that in case the retainingtongues 16 should not, for any reason, he engaged'beneath the lip or fillet to properly hold the closure in-- contact u onthe top surface 3 of the said lip or fi let, whereby the closure mi ht be tilted up at one side, as shown at. the right-hand side in -Fig. 3, the contact ofthe closure around thc' peripheral surface of 'thelip or fillet will still'sufi'ice to prevent entry of impuritiesor (lischarge'of the contents.

The retaining tongues or projection's 16,

Such connection also insures removal so and comparatively inexpensive nature, and

permits of displayin t herein shown bent outwardly as seen at 17 "the application of well suited for employment 1'}? bottle is" inverted, so as=to efi'ectivel 1 6 are of substantially equal thickness throughout, but their lower extremities are to afford hook like parts which are in registry at different points around the bottle neck, as shown in Figs. 1 and 3. These hook-like parts are .not essential to my invention, but where rovided, they faci itate ihe closure to the bottle by afi'ordin rounded inner surfaces for contact upon t e sloping surfaces at the top of the lip or fillet.

The improved bottle closure constructed according to'.my invention is Particularly connection with milk bottles by reason 0 the convenience with which it may be applied to and removed from the bottle during use, and also by'reason of the security. with which the contents of the bottle are protectedboth against the entry of impurities, or accidental discharge, the closure, when in position upon the bottle, being retained in place by the spring en agement of its retaining tongues 16 beneat P f vent the escape of the contents. It Will also be obvious from the above description that the bottle closure constructed in accordance with iny invention is of an extremely simple e time of bottling the milk, and it will evident that the device is susceptible of some modification without material departure from the rinciples and s irit of the invention an for this reason do not desire to be understood as limiting myself to the precise formation and arrangement of the several parts as the bottle lip even when the herein .set forth in carrying out my inven- I claim and desire to secure by Letters Pat In combination with a bottle neck provided with an annular outwardly directed fillet extended around its mouth, the upper surface thereof being rounded in profile and the lower part of said fillet being sloped,in-. wardly to produce a curved shoulder; of an inner compressible member extending across the-opening of the neck and bein of such diameter that its marginal portion a s over the rounded upper surfaceof the fil et and extended down about the fillet in cylindrical form, the central portionof the member being depressed below the marginal portion, an outer metallic member annular in form and extending over the mouth of the neck and having a central opening to expose the inner member, said outer member having a depressed edge portion surrounding its central aperture and havin a marginal curved portion conforming to t e u'pper curved sur-,
