According to the present inventions-these lvaried requirements aresatisi'ied by the provision ofy a glass containerfor `Isupporting laninverted bottle and having a sumpin .combination with an insert of nonfmetallic. materiahsuch-.asgbakeflite or a material having similarlproperties, for cooperation with `a plunger constructed `and mounted in a particularly 4effective nranner. This construction isespecially satisactoryfwhen employed 'in combination with ,certainy otherfea# tures hereafter described in detail.- Bythe prof vision .of ra glass containerthere.isproduceda very `attractive dispenser, 4adaptedjfto pleasingly glass alone.

Another feature ofthe invention .residesin an improved dispenser construction including an improved top and a plunger carried with the'toptand cooperatmg with the insert :to-dispense Vliquid from the sump. The entire structure is simple and inexpensive tomanufactureand yeasyto assemble, besides being readily laccessiblefor cleaning and providing .a minimum ,of surfacesvand spaces for the ,accumulation of ldirt and,y germs.

Other features .of the; invention', including cerf ltain specic improvements, and other advantages, will become apparent in connection; with the following detailed description of .onepreferred form of mvnvention, reference :being had'toftheface eempanying drawing, wherein: '1

In the drawing, there is shown at 1 a container foriiquids including a wall 2, bottom 3, sump 44, andsbase 5. In order to accommodate aninverted-bottle 6 and at the same time make provisionfor. a short, noni-drip spout, such as will i be hereafter .described in detail, the wall 2 is preferably y.generally rcircular but has an oiset por.- tionr'l forming ya Vwall of the lsump liwhich, is

also offset. The container 1 may preferably .be y

formed `as lan integral cast glass unit,V wherein r thexbottom 3 of the reservoir slopes slightly towardthe sump 4 and the base 5 is a flared con,-` tinuation of wall 2,y though these portions ofthev container maytake other ,desired shapes. Rubber .padszS may be secured to the :bottom of .base 5,A in any suitable manner, to form Ia cushion ybectween the .container and any flat surface `9 upon which itis adapted to stand. i ,e

I-The top 10 of the .dispenser may advantageously beprovided with a groove l1 iormed between flanges 12 and. 13 and adapted to .receivecthe upper. edge of wa1l277 about its entire perimeten Ifidesired, spaced feet 14 may be formed on .the top, within,- the groove, to rest on the upper .edge ofithe glass in` [order to prevent the glass from becoming wedged` in the groove. However; while` a .particularly .eifective construction may be achieved in this manner, .one'of these flanges mightpbe Yomitted.,if desired, or some other arrangement vmight be employed for the purpose. indicated. Theflanges 12 and 13 and feet 14 arefpreferably so arrangedcthat air mayenter the interior .of the .container by passing between the flanges .and wall 2 between the feet. The top 10l may 'have an annulares'haped portion 15 forme. ing iacen'tral opening to receive the neck of an inver-ted .bottle .6, and a shouldered portion 16 for seating a -ring 17'of rubber orother cushioning material upon which thebottle is adaptedto rest. i i sAlsosecuredfto. and preferably :formed intesrallwith i.tlietcm A1,0 there may-be provided. a cylindrical sleeve 20 `forming a guide for a tube 2 1c onv,eniently formed o-fmetal and adapted to carry a meneer element 22 for kdisplacing liqu frornfthe'sump. 1'Iube21 serves to convey theliqlld displaced to a glassor kother receptacle heldibelew vthe meuth 23 ef the tube. The tube .2.1isrece'redwithin the .Sleeve 20 and may be rrevided with e key :Medepted t0 Slide in a kev- Way 25 for-med, at-one side of the sleeve, to prevent the tube 21 from turning. A coil spring 26, for raising thetube after it has been depressed, mey-surroundrthe tube ;2.1 and lie snugly between the semeand the inside wall of sleeve 20, resting on shoulder 27 formed on the top 10 and abutting against shoulder 28 on the tube. The lower end of tube 21 preferably extends downwardly into an opening formed centrally of shoulder 27, and has a sliding fit with the walls of the opening.

Through this construction of the top 10 provision is made not only for supporting an inverted bottle carrying a relatively large supply of the liquid to be dispensed, but also for a simple and effective mounting of the discharge tube and plunger construction in the top of the dispenser. Furthermore, the top 10, when composed of metal may be cast, pressed or otherwise formed -asasingle piece, thus greatly simplifying manufacturing operations. l may be removed from the container 1 in a moments time when the device is t be packed for shipping or is to be cleaned after use; i

Fitted into and lining the sump 4, andpreff erably removable therefrom, there is provided a generally cylindrical memberv or insert 30having an opening 31 at the side facing the main portion of the container surrounded by Vwall 2.

and having the balance of its periphery closely adjacent to or in contact with wall 7. The bottom 32 of the opening 31 is preferably adapted to lie at the level of the bottom?, of the container. f, The opening 31 may extend to the top of the inem'- ber 30, or if preferred, may extend upwardly merely a distance sufcient to'permit liquid to flow into thesump. In either case the wall of the insert above the level of bottom 3 will preferably form the greater portion of a cylinder. The upper edge 33 of member 30 preferably abuts against anges 13 on top 10. Ears 34 formed on Ithe member 30 serve to maintain the `member against turning, through abutment with wall 7.

The plunger 22 may have al tubular portion 35 and an enlarged lower end portion 36 'adapted'to have a sliding fit in the member 30,- the side walls 37 of which actas a guide for the plunger. For securing the plunger 22 to tube 20 a threaded sleeve or nipple 40 may be secured totherplungerv in any convenient manner, as by screw threads or by being embedded in the material of the plunger, and it may be adapted to be screwedinto threads 41 atthe lower end of the tube 20. `Abut ment of the upper end 42 of plunger`22 against a surface on the top serves to limit. upward movement of the tube andplunger under the action .of spring 26, thev plunger preferably being of such length and so arranged that when it is in normal, raised position no other Vparts of the displacing mechanism need vbeL in contact with the liquid. VIf desired the arrangement may be such that theplunger is not completely immersed in the liquid even when depressed in the manner. to be explained. In assembling the construction it is merely necessary to insert the spring 26 and tube 21 in the sleeve 20 and screw the threaded sleeve V40k into the tube. The cover' 10 may then be put in place after the memberv30 has been slipped into the container 1.v f

The member 30 and the plunger 22 may pref erably be formed of bakelite or the like, or some other suitablenon-metallic material such as hard rubber. Through this construction not only is accurate measurement of theliquid secured but the imparting of a metallic taste tothe same is avoided and at the Sametime a glass container may be employed both for its attractive appearance and relatively low cost. Moreover, the member 30 besides serving as anac'curate measuring sump acts as a guide for theplunger22, as mentioned. 1 Furthermore, lthe, parts f are fall simple and inexpensive to manufacture, few in number and easily assembled.

The upper end'of the tube 21 adjacent the mouth 23 is preferably constructed so that the lip 45 does not extend horizontally to any appreciable extent but lies generally in line with the front wall of the tube 21, while the portion 46 overliesvtheupper end of thetube and extends outwardly beyondthe lip,.providing curved surface 47 for directing the ow of the liquid. Such aspout is particularly effective, for preventing drip, especially apt to occur with Syrups, and may Lbe employed to good advantage with the off-set sump arrangement, which permits the short spout to lie adjacent the line of the front wall of the dispenser. Moreover, this construction providesl for delivery of the liquid in a di- "frection outwardlyof the device, so that the glass p, into which the fluid is to be delivered need not be held close to or against the device, thus avoiding chipping of glasses.

The operation of the device will no doubt be apparent lfrom the above description of its construction, but it may be here briefly summarized. Upon .placing a bottle in inverted position on the device'as sho-Wn the liquid will ll the container 1 up to the level where it seals the mouth of the bottle, whereupon by depressing the tube 21 and plunger 22A to its'maximum extent of travel a definite-v quantity of syrup will be expelled through'mouth 23. In this manner, the accuracy of measurement is insured by reason of the fact that on the one'hand the level of liquid in the container is always constant as long as there is some liquid in the inverted bottle, due tothe dipseal, and on the other hand the plunger cuts off or segregates an exact quantity of liquid from the bulk rin' thecontainer before the dispensing action begins. There is `thus' always displaced from within 'the plunger the same vamount of liquid. When the device is empty and an inverted bottle is put in place the level of the liquid automatically adjusts itself, and when that bottle is just empty the attendant need only replace it with arfull one. i The possibility of error in operating the device is accordingly reduced to a minimum.

While the invention has been described in 'connectionV with andis particularly adapted for use with an inverted bottle, it will be understood that certain of the features disclosed are similarly advantageous when the liquid is supplied to the container in other manners.

The'terms and expressions which have been employed are used asv terms of description and not of limitation, andthereV is no intention in the use' ofy such' terms and expressions, of excluding any equivalents of the features shown and described, or portions thereof, but it is recognized. that various modifications are possible within/the `scope of the invention claimed.
