SERVICE-COVER FOR MILK-BOTTLES, JARS, @acA Application filed October 23,

To rlZZ whom t may concern:

Beit known that I, BLANoiin Slirrii Pinnen, a citizen of the United States ot America, residing at Grand Rapids, in the county of Kent and State of l\lichigan, haye invented a new and useful Improvement in Service-Covers for Milk-Bottles, Jars, &c., of Which the following is a specification.

My invention relates to improvements in covers for bottles, jars, etc., and more particularly to special coversto close the ori fiees of suoli vessels while in service after the regulation cover, cap or seal provided for closing same has been removed.

The objects of my invention are to provide a device for the purpose which is simple, durable, ellicient, easily cleaned and sterilized, easy and cheap to manufacture,

and capable of being applied or removed by hand Without the use of any tool.. These and other objects of my invention ivill more the following descrip- Y tion.

'suitable material, as, kInercial sheet aluminum or tin, having an My invention consists essentially of the various novel eatiires of construction and arrangement of parts hereinafter more fully described and particularly pointed out in the claims, reference being had to the accompanying drawings illustrating a device embodying in v invention and the best mode contemplated b) me l'or applying` my invention in practice.

A cover constructed in accordai'ice with in v invention consists ot' a single piece of for example, com

\v itli the orilice ot' annular Hat portion for contactinglf annular top suriace adlioining,r the ythe vessel; an annular stillfeiiing` rim at the exterior of the fiat annular contactingr portion; and two diainetrically opposite clamp ing portions in the forni ot lugs or ears, depending from the edge of the annular still'- ening rim, to elastic-ally engage the exterior side surfaces adjacent the orilice of the ves-- sel and thus hold the cover in place against light accidental forces tending to dislodge it. Preferably, to further assist in main1 taining' the flatness of the annular contacting` portion, the cen ralportion, within the fiat annular contacting portion, is offset from the plane of the flat contacting p0rtion.

The` material from which the cover is made is preferably somewhat elastic or springy and the clamping lugs are preferl Specification of Letters Patent.

ably so shaped as to conform approximately to the exterior form of the siifles of the oriA lice olf the vessel ad'ji'icent its iop. 'lhis construction renders it easy to apply the cover to or remove it from the oril'ice ol the vessel by hand, without any tool, and it also provides for automatically adapting the cover to such variances in the external form and diameters of the oriliees et' the vessels of a standard type and size as is commonly met with in the commercial production of such articles.

A cover made .in accordance with my invention is not designed to be used as a leak proof closure to the orifice of the vessel, as is the regulation rover. cap or seal pro vided for that purpose 'for certain bottles, jars, etc., but it is designed to be used as a service cover `for the orilice of' the vessel so as to protect its contents from dust, insects, etc., al'ter the regulationcover. mp or Seal has been removed and its replacement is not desired, For ,fniple, the ,seal generally used for bottles ir. Ywhich niilli and cream are delivered to il' of a ,sott eaidlgioa'rl disk of rather heavy and which lits snugly in a suitable internal the seal out oi' its recess, vvitli the result that the seal is generally so injured in Yiis nioval as to render it inadiipiate or at least undesirable for further service, and such a seal is generally discardiil upon its first removal from the bottle, lvllien the regiilation seal has been removed `from such ay bottle the contents of the bottle are availm able for service as needs nn require from time to time, and the bottle may then be said to be in service. lt is durirgor the period ivliile the bottle is thus in service and its contents being dra un upon as desired that iny special cover is put in service on the bottle to protect its icifiiainimgr contents-- hence l have appropriately designated it a serv ice cover.

Referring now to the accompanying drawings: Figure l is a top View of one form of my improved cover; Fig. 2 is a side view of the upper portion of a common milk bottle having my improved cover, partly in section, thereon; Fig. 3 is a vea-ti cal central section on line A--B of Fig, 52; Fig. Ll is a central cross-section of my iniproved cover showing the central portion 6. annular rim 2 as much as may be necesportion 1.

depressed instead of raised, as is shown in the other figures; Figs. 5 and 6 are side views, partly in section, of a form of my improved cover, showing an additional ear forming a limit stop and facilitating the engagement and disengagement of the cover from the vessel; Figs. 7 and 8 are side'views of my improved cover as applied to a jar or common tumbler.

Like numbers refer to like parts in all of the figures.

Of the parts: 1 is the flat annular portion which contacts with the annular top surface adjoining lthe orifice of the vessel; 2 vis the annular rim formed integrally with and exterior to part 1 to stii'en same; 3 is:

the pair of oppositely disposed lugs, depending from and formed 'integrally with part 2, which by their clamping action hold the cover in place over the or1fice;,4is an additional lug or ear employed in one form of my device, depending from the rim 2, as shown in Figs. 5, 6,7 and 8,*which facilitates the engagement and disengagement of the cover from the vessel; 5v is the central raised or depressed portion within part 1, and 6 isA the annular offset formed integrally with and joining 'parts 1 and 5 and serves toA aid in maintaining the iatness of part 1 against its accidental deformation.

Sanitary considerations require that the cover be of such form in its ,several parts as to avoid the formation of recesses or corners diiiicult of access for thorough cleaning. To satisfy that requirement in my improved cover the annular stiiiening rim 2 and the offset 6 are preferably not formed abruptly, but as shown in the sectionalportions of Figs. 2 and 6.

The annular curved rim 2 is not designed to make contact with the bottle or jar, but serves simply to stillen the fiat contacting ably stands away from the bottle a small amount as shown at 7 in the sectional portion of Fig. 2. This provision insures that the flat contacting portion 1 may be made wide enough to adapt one size of the cover successfully to the top of bottles ofa standard type and size by allowing for the variances commonly met with in their commercial production. Additional stifening of the cross-section of the cover may evidently be provided by forming annular corrugations in parts l and, 5, but as such corrugatlons would make the cleaning of the coverv more difficult I prefer to avoid their employ- 'ment and instead thereof to increase the amount of the oii'set 6 and the depth of the sary to provide any desired degree of stiffness'of the cross-section.

-By making the form of lugs approxi- The rim 2, therefore, prefer-y in a plane practically parallel to its flat surfaces and in a direction at right angles to a line through the middle lof the lugs 3. When used with a jar having a top similar to that shown in Figs. 7 and 8, my improved cover may be applied Aor removed mthe manner above described Aor by vertical movements as may be referred-by the user.

The ,lug 4 facilitates the placing of the cover on the bottle by affording agood surface against which tocpress when forcing the clamping lugs 3 into proper engagement with the sides of the vessel, and it also facilitates the engagement by forming a stop which prevents forcing the cover too far over when applying it. The disengage-f ment of the cover is facilitatedby the lug 4 which affords a hold for the tips of the fingers or nails when withdrawing the cover from the bottle. J

Variations in the forms of the elements of my invention, from those specifically shown and described above, may be made without departing from the essentials of those elements or of the invention as a whole, and I would include as within the scope of my invention such available variations in the form of' its elements as may be found desirable in adapting it to its various possibilities of service.

I declare the above to be so full and clear a specification of my invention as to enable others skilled in the art to which it pertains to make and use the same.

`What I claim as my invention is:

1. A service cover for a bottle, jar or other vessel, comprising, in a single piece of suitable thin and flexible sheet metal, an annular vessel-top-contacting portion, a pair of oppositely disposed securing lugs depending ,from the outer edge of the vesseltop-contacting portion, and a third lug also depending from the outer edge of the vesseltop-contacting portion, and located midway circumferentially thereon between the two securing lugs, to facilitate the manual application of the cover to and its removal from the top of the vessel, substantially as shown and described.

2. A service cover for a bottle, jar or other vessel, comprising, in a single piece of suitable thin and flexible sheet metal, an annular vessel-top-contacting portion. an

lng rim portion, a raised portion within the annular vessel-top-contacting portion whereby an annular offset is provded'at the junction of the two last named portions for the purpose of further stil'ening the cover, and

r10 a third lug` depending from the external annular stifl'ening rin; portionr` and loCated midway cirumferentially thereon between the two securing lugs, to facilitate the manual application of the cover to and its rennvnal from the top ot' the \i.-zsel, substantizlllyy :1s described.

ln te tin|ony hereof I alix my signature to this specification in the presence of two witnesses.
