Patented Dec. 30, 1952 UNITED STATES PATT' 4OiliiffICE 2,623,368 srILLPRooF GLASS Edward Fzylsen, Hillman, Mich. Applicationiuiy 13, 1950, serial Nu. rzs'gsso provide a formed or molded cover construction which is adapted for positioning over the open end of a uid container and which is provided with a plurality of spaced openings in communication with 'the interior of such container through which the fluid may bewithdrawn or sucked therethrough by a child.

It is the further object of this invention to provide a substantially simplied'container cover construction which is durable and fully effective for the intended purpose.

These and other objects will bel seen'from the following specification and claim inconjunction with the appended drawings in which-'- Fig. l is an elevational section-of-acontainer with the present cover removably vpositioned thereon.

Fig. 2 is a plan view thereof.

Fig. 7 is a plan View thereof. y

Fig. 8 is a section taken on line 8-8 of Fig. 6.

Fig. Sis a section on line 9-9'of Fig. 6.

Fig. 10 is an elevational view of acontainer and cap partially in section-and illustrating a variation in the constructionof the fluidoutlet device; and y Fig. 11 is a plan view thereof.

It `will'be understood that the above drawings illustrate merely preferred embodiments ofthe invention and that other embodiments are contemplated within the scope ofthe claims here- Referring towFigms. l and-2 of the drawing the fluid container I l has a bottom portion generally indicated at l2 whichmay forni a unitary part of the container or whichmay be a removable circular section I3 having anA annular flange 14 Aat`its lower end positioned withinA a corresponding annular recess in the annular shoulder l5 at the lower end of lsaid c'ontainer,'-v.fhose upper end is open as at l1.

A plurality of spacedannular extensions `I8 are formedwithin the outer wall of container Il `adjacent its upper `vend adapted for retaining registry with corresponding annular projections El upon the inner surface -ofthesi'de walls ofthe container cover I9, `whoselower endvfterminates in the annular bead 20. y

Said cover has a circular upperportion 22 within which are formed a series of spaced circularly arranged uid outlet openings 23 f as shown in Fig.` 2. The-cover includes-'an annular centrally depressed portion 24 with a fiat central surface 25 positioned withintthe interior of said container at-its vupper end I1.

In operation a child Ymay drink from the container Il by placing the upper rounded` portion 22 between his' lips and suck through a plurality of outlet openings 23, there being sucient uncoveredopenings remaining in the cover to permit the entry of air to-facilitate the now of iiuid from said container.

While annular `projections or threads 'I8l and 2| are illustrated inFig.` l it is contemplated that these could be entirely eliminated withthe inner surfaces of the `annular cap frictionally bearing against Ithe exterior upper surface of the container Il. On theotherhandthe cap Vmay be secured to the container by` including an annular ange such as the ange 52 shown :in'Fig 6 which is positionable within correspondingv annular recess 50 in the outer surface of i the container.

Figs. 3 and 4 illustrate a variation in the construction shown in Figs. l and 2, there being a container 2t` with open end 2'!l andv a series or" annular projections or threads 28 formed `within the outer surface of said container to cooperatively receive corresponding annularprojections 29 formed within the innersurface of the cap 3@ whose lower peripheralfedge terminates in the annular bead 3| which engages the outer surface of i said container.

Said cap or cover30 includes an upper .annular rounded portion 32 with aplurality-of spaced transverse openings 33 formed-therein infac'ircular arrangementas indicatedfin Fig; 4; providing communication to the interior ofysaid container.

Said cap includes centrally depressed Aannular portion 34 with a `central fiat Aportion 35" positioned within the upper open 'end 21 ofsaid container, there being a plurality of fluid inlet vopenings 365 formed vvithintheV flat portion 35.

A valve disc 31 preferably constructed of soft rubber is positioned below the flat wall and has a stem 38 which is centrally joined thereto and slidably projects upwardly through the circular opening in said flat portion 35 whereby upon inversion of container 26 the said valve will close the openings 39 and prevent the escape of liquid therethrough. Upon the other hand when the container 26 is in upright position it may be reiilled lwithout removal of its cover 30 merely by pouring liquid down into the depressed portion 34 of said cap whence it flows through the openings 35 and into the interior of said container, through opening 39.

Fig. 5 is a plan View illustrating a slight variation of the construction shown in Figs. 1 and 2 inasmuch as the cover lll for container 40 has an upper annular portion 42 within which are formed a plurality of iiuid outlet openings 43 arranged in the arc of a circle. Said cover has an annular depressed portion 44 and a flat portion 95 at the bottom thereof just as in the construction shown in Figs. 1 and 3. Air inlet opening 451s formed within the top portion 42 of said cover, being arranged upon the opposite side of said cover from the arcuate row of openings 43.

A slight variation of the present cover construction is shown in Fig. 6 adapted for container l? with integral bottom 48 and having an upper slightly inwardly inclined open portion 49 with an annular recess 59 formed within its outer surface.

The cover 58 for 'said container includes the annular downwardly extending flanged portion 5i whose inner surface cooperatively 'bears against the exterior surface ofsaid container at its upper end, there being an annular projection 52 upon the interior wall of flange 5| adapted for retaining registry within recess of said container.

Said cover also includes an upwardly extending annularly flanged portion 55 as shown in Fig, 6 through which extend a plurality of downwardly and inwardly inclined crcularly arranged fluid outlet passages ,54, whose lower ends are in communication with the cylindrical bore 56 upon the under side of the horizontal portion of cover 59, and whose upper ends terminate in the rounded top portion 53 of said flange.

The circular disc 59 is positioned Within the bore 56 of the cover 58 and bears upon the upper peripheral edge of container 47 and has formed therein and therethrough a plurality of spaced circularly arranged iluid outlet openings 60 in communication with the interior of ysaid container.

A seco-nd disc 61 is positioned within the bore 56 and rests upon disc 59, the outer peripheral portion 52 of said dise being of reduced thickness. A plurality of inwardly extending arcuate notches 63 are formed through the outer peripheral edge of the disc 6| in spaced relation and are arranged entirely around the periphery of said disc. Thus there is provided adequate passageways 99 and 83 through the discs 59 and 6l within the bore 56 through which fluid from said container may pass and be withdrawn through a plurality of the inclined passages 54.

It is apparentrby this construction that there will be little or no escape of fluid from said container in the event that the same should be accidentally displaced.

While the construction shown in Fig. 6 illus- Y rates the cover flange 5l upon the outside of the container, it is contemplated that said annular iiange could just as well snugly engage the interior surface of the container at its upper end.

'4 Furthermore while the cover is snapped on in view of the annular flange 52 and corresponding recess 59, it is contemplated that said cover could be threaded upon said container in the manner illustrated in Figs. 1 and 3.

The present construction is particularly adapted for the use of young children in teaching them to drink alone from a glass. An accidental upsetting of the glass will cause little or no spilling of the fluid contained therein.

Another variation of the present invention is shown in Fig. 10 which shows a container 64 with upper open end 65 over which is positioned a cover 06 having an annular depending iiange Si which frictionally and cooperatively bears against the outer surface of said container at its upper end.

An elongated arcuate angularly inclined spout 53 is formed upon the top of cover 63 and a plurality of arcuately arranged elongated similarly inclined channels 59 are formed therein and through which a child may withdraw iiuid. it will be noted that an air inlet opening 79 is also provided within cover 55 upon its opposite side as shown in Fig. 10.

Having described my invention reference should now be had to the claim which follows for determining the scope thereof.

I claim:

In combination with a iiuid container having a circular open end, a dome shaped cover removably secured thereover, and an elongated outlet spout of wedge shape in vertical cross-section extending upwardly from one side of said cover in substantial alignment with the side wall of said container and of sufcient horizontal extent to have formed therein a series of substantially v-ertical apertures in communication with the interior of said cover, said cover having formed therein an air inlet opening spaced from said spout, said apertures being in substantial alignment with the side wall of said cover.
