Piker, Wyoming, Ohio, assignor to The Hamilton-Sketch Corporation, Hamilton, Ohio, a corporation of Ohio Filed Jan. 21, 1966, Ser. No. 522,238 11 Claims. (Cl. 62-398) This invention relates to improvements in cooler chests and particularly to such chests when arranged to maintain a container and its contents, while in the chest, at a desired temperature.

The principal object of this invention is, therefore, the provision of a cooler chest adapted to hold or have disposed therein a container which would contain material, such as liquids, to be dispensed at a given temperature, whether hot or cold.

Another object of this invention is the provision of a cooler chest in which is disposed a container for liquids and which container discharges therefrom the liquids in individual servings together with means within the cooler for maintaining the container with its liquid in a cool or cold condition.

Another object of this invention is the provision of a cooler chest wherein removable bottles or other rechargable holders are disposed to embrace a container for beverages, which bottles or other rechargable holders contain a refrigerating or cooling medium for maintaining the beverage in the beverage container in a cold refreshing condition.

Other objects and advantages of the present invention should be readily apparent by reference to the following specification considered in conjunction with the accompanying drawings forming a part thereof and it is to be understood that any modifications may be made in the exact structural details there shown and described, within the scope of the appended claims, without departing from or exceeding the spirit of the invention.

FIG. 1 is a perspective view of the cooler chest of the present invention in its usable operative position.

FIG. 2 is an end elevational view of the cooler chest of FIG. 1.

FIG. 3 is a longitudinal elevational view of the cooler chest of FIGS. 1 and 2 as seen, for example, from the rear side thereof.

FIG. 4 is an end elevational view of the cooler chest of the present invention, similar to FIG. 2, showing the cooler chest in its operative position, such as seen in FIG. 1.

FIG. 5 is a longitudinal sectional view of the cooler as seen from line 55 in FIG. 2.

FIG. 6 is a plan view of the interior of the cover or lid of the cooler chest of the present invention, as seen looking in the direction of the arrows 66 on FIG. 5.

FIG. 7 is a top plan view of the interior of the cooler chest and its contents, as seen looking in the direction of the arrows 7-7 on FIG. 5.

FIG. 8 is a fragmentary, sectional view through the cover or lid of the cooler chest as seen from line 8-8 on FIG. 6.

FIG. 9 is a fragmentary, enlarged, sectional view through the bottom of the cooler chest as seen from line 99 on FIG. 5.

Throughout the several views of the drawings similar reference characters are employed to denote the same or similar parts.

As noted above the present invention rel-ates to a cooler chest for use with a container from which a beverage, such as beer, may be dispensed into individual glasses, mugs, and the like, and which beverage is maintained in 3,338,068 Patented Aug. 29, 1967 its cool or cold condition from start to finish of the dispensing from said enclosed container.

In other words, this invention is adapted for use in dispensing a beverage, such as beer, from a container containing a relatively large amount, or a relatively large number of glasses of said beverage, such as a pony keg and with said keg and its contents maintained in its iced or refrigerated condition from the time it was brewed until the last glass full has been drawn therefrom.

The cooler chest of the present invention, indicated in its entirety by the reference numeral 10, comprises a bottom 11 from the ends of which upstand end walls 12 and 13 which have their similar opposite ends connected to one another by a back wall 14 and a front wall 15, integral with and upstanding from the bottom 11. Hingedly connected, as by hinges 16 and 17 to the upper end of the back wall 14 is a lid or cover 18. The lid or cover 18 is adapted to be releasably latched in its closed position by a latching member or strap 19 cooperating with a latching .pin 20.

As seen in FIG. 5, for example, the cooler chest 10 comprises an outer plastic shell 21 and an inner plastic liner 22 nested with respect to one another to provide a space between said shells in which is disposed insulation 23. It is to be understood that it is the spaced shells together with the insulation therebetween that provide the cooler chest bottom 11, end walls 12 and 13 and front and back walls 14 and 15.

Any suitable or desired method may be employed with respect to forming and positioning said chest shells, that illustrated in the drawings consisting of the inner liner 22 at the upper ends of its end walls and front and back walls having outwardly projecting walls forming top members 24 which are projecting in a substantially horizontal plane for a perceptible distance, that is, the width of the insulation plus the thickness of the outer shell upstanding wall members, all as seen in FIG. 5. At the outer edge of each of said walls top members 24 there is provided an integral downwardly extending flange 25 which controls the upper ends and depends exteriorly of the outer shell end walls, front wall and back wall for thereby effecting a gauge for the spacing of the said inner and outer shells bottom, end walls and front and back walls, from one another. There is disposed within the space between said shells insulation 23 which also effectively locks the cooler chest shell and liner in the positions above set forth. It should be noted that the said insulation 23 is initially in the form of liquids which upon being brought into association with one another chemically react as a foam which readily hardens into the plastic foam insulation, as is well known and this solidified foam insulation positively prevents separation of the inner liner from the outer shell, as illustrated in FIG. 5.

The cover 18 similar to the cooler chest, per se, is formed of an inner liner 26 and an outer shell 27 with said outer shell similar to the chest inner shell having at its outer edge a depending flange 27 that engages with the inner surface and depends below the upstanding wall flange 28 of the lid or cover inner liner 26. The said lid inner liner is provided inwardly of its upstanding flange 28 with a fiat surface 29 that is similar, in size, to and engages with the flat upper wall surface of the chest walls and said flat surfaces are in face contact or engagement with one another on the upper ends of each of the cooler chest end, front and back walls.

The said chest Walls top or flat member 24 is provided substantially centrally thereof with a downwardly projecting groove 30 to receive a similar formed complementary bead 31 downwardly projecting from the lid or cover flat end, side and back walls, top walls or flat faces 29. The

said groove and bead 30 and 31 when interengaged with the lid or cover 16 is in its closed position acts as a seal against any inadvertent loss of cold within the chest, per Se. To further discourage loss of cold from within the chest the cover or lid inner shell 26 is provided at the inner edge of its flat surface or wall 29 with a depending bead or lip 32 which enters the chest at the upper end thereof. This bead or lip 32 engages with the inner surface of the chest end, front and back walls at and just downwardly of the upper ends thereof and serves as a positioning means for positioning the cover with respect to the chest and thereby insures the interengagement of the groove and bead, 30 and 31, and at the same time acts as an additional seal against loss of cold from the chest and the entrance thereinto the warmer atmospheric air.

As disclosed in FIG. a container, here illustrated as what is generally called a pony keg, indicated in general by the reference numeral 33, having each end countersunk to provide a top portion or head 34 and a bottom portion or lower end 35. The bottom end 35 together with the recess outwardly thereof is adapted to embrace an upstanding centering member indicated in its entirety by the reference numeral 36.

The centering member 36 is formed of plastic the same as the inner and outer liners 21 and 22 with said centering member 36 being cylindrical in form and having an upstanding portion which includes a substantially, circular, ring-like top 37 from the inner and outer peripheries of which depends legs 38 and 39. In order that the upstanding ring of the centering device may readily enter the concavity 36 at. the lower end of the keg the said ring has the inner leg thereof of less height than its outer leg 39 with the top connecting portion concaved in connecting the different heights of the legs 38 and 39.

The said centering device 36 has its outer legs 39 integral with an outwardly projecting flange 40 and the lower end of the inner legs 38 are connected by a web or bottom 41.

The centering mechanism 36 may be formed integral with the bottom 42 of the inner shell 22, but, since the kegs 33 are machine spun they may differ in actual size from One another a relatively small amount, but, the dif ference is such that a fixed centering member 36 would encounter possible difiiculty in having successive kegs properly centered; also, and as will shortly be made clear, the cooling devices may be such that a slightly off dimension, or unfamiliarity of the assembly of the parts by the user may again offer difficulty in the assemblying of the parts for return to the original producer.

In all instances, however, the concentricity of the bottom concavity 35 of the keg will permit the entry of the centering member 36 and it has further been found that the material alignment of the keg bottom cavity and centering device is in the longitudinal direction of the chest. As seen, therefore, in FIGS. 5 and 9, the chest inner liner bottom 42 is provided with a undulated upper surface 43 and the centering mechanism flange 40 and base 41 are similarly provided with undulations 43 substantially identical with that of the chest liner bottom. With this arrangement the centering device 36 is held in substantially concentric relation with respect to the chest bottom and will thereby receive enough of the keg bottom concavity to automatically shift the centering device to align axially with respect to the axis of the keg.

As seen in FIGS. 1, 5 and 7, the cooler chest encloses,- on each side of the keg 33, in the longitudinal direction of the said chest, similar cooling devices hereinafter called, as they are each referred to in the trade, a bottle 45 and 46. Since each of these bottles is identical with the other and, in fact, may be interchanged with respect to one another, only one of them will be described in detail.

Accordingly the bottle 45 is of a height slightly less than the height of the keg itself and has at its upper end a top 47 which is, in the broad sense of the word, crescent shaped in a horizontal plane to include the central portion 48 and the side or wing portions 49 and 50. For convenience in assembling the bottles with respect to the chest and keg, the body portion 48 is provided, along one vertical face, preferably the outer face, with inwardly formed reinforcing ribs 51 which permit a slight displacement, if needed or necessary, in the bottle body portion when being positioned.

Extending upwardly from the top 47 of each bottle, substantially on a line centrally longitudinally of the cooler chest, is a neck 52 provided with screw threads 53 through which a closure cap 54 is secured in operative position.

Extending upwardly from the top of each bottle, one on each side of the filling neck and closure cap 54, are lugs 55 and 56 through which the said bottles are engaged for lifting the same from the chest and through which hand-hold pieces the said bottles are lowered into their proper and operative positions.

In other words, each bottle through its upstanding hand-holds 55 and 56 may be removed from the chest and after removal of the cap 54, ice in chopped or cubed form and condition inserted within the bottle, or the bottle may be filled with water and then frozen in a suitable freezer, or a refrigerant in liquid disposed within each bottle and whereupon the bottles are returned to their operative positions. It is understood of course that the kegs 33 upon being filled at the brewery are immediately or shortly thereafter chilled or cooled as is the usual custom, whereupon the said filled keg is disposed within the cooler chest and the bottles disposed adjacent thereto for maintaining the keg and its contents at the cool temperature as desired and which chest with its keg is then shipped to a customer, or to a retail point for subsequent delivery to a customer or user.

The cooler chest is provided at the upper ends of its end walls with thickened portions 57 and 58 eachof which has an under surface 59 and 60 for a users hand in raising and positioning the cooler chest with respect to Y a supporting table or the like. Said table is illustrated in FIGS. 1 and 4 and identified by the reference numeral 61.

The enlarged handle or grip portions 57 and 58 are each further adapted to provide a pivot 62 for the inner end of a leg 63 of a bail type carrying means which also includes a connecting handle 64. As shown in FIGS. 1 and 4 the handle 64 may be arranged to be beneath the back side of the chest and thereby, in effect, level or dispose the longitudinal axis of the chest in a plane substantially horizontal to the upper surface or plane of the table or other support 61 since as seen particularly in FIGS. 1, 2, 3 and 4, the sides of the cooler chest taper downwardly from the top thereof. This tapering of the ends, front and back walls of the chest being for appearance sake as well as of necessity due to the depth of the draw of the chest inner and outer members while in the process of manufacture.

With the cooler chest in position, therefore, as illustrated in FIGS. land 4, the cover or lid extends outwardly therefrom on the hinges 14 and 15 thereof. The said lid or cover, as further illustrated in FIGS. 6 and 8, is provided for a considerable area of the inner or under surface thereof, that is, within the positioning lip 32 with a depressed surface which could and does, as will presently be made clear, act as a supporting bar for glasses or other individual containers for the beverage within the keg.

As illustrated in FIG. 1 the keg 33 has extending from the base of the upper depression or of its top member 34 a dispensing cock 65 which is manually controlled, as is very well-known, for dispensing beverage from the said keg. The filled glasses or other individual containers are then disposed on the now exposed inner surface cover or lid 16 as illustrated in FIG. 1. In order to maintain the said lid or cover 16 in the position thereof as illustrated in FIG. 1, and in solid lines in FIG. 4, use is made of positioning or holding straps 66 and 67 each of which has its inner end secured at 68 to the inner surface of the positioning lip 32 of the cover or lid inner member or liner 20, with each strap having its other end secured as at 69 somewhat below the upper ends of the end walls and 11 to be just below the inner edge of the cover or lid positioning lip.

As illustrated in FIGS. 6 and 8 the said exposed surface of the cover or lid 16, that is the lid-liner, lid-bar, 20, is provided with a series of alternating hills and dales 70 into which any drainage from the glasses or other individual containers will drain so that the upper surface of the lid-bar is not overrunning and thereby cause or permit a drippage from the bottom of said glasses or other containers in transferring them from said lid or cover-bar surface.

The arrangement of the parts are such that an average beer glass or tumbler, as illustrated in FIG. 1 by dot and dash lines 71, will be accommodated while to fill what is known as pilsner glass it will be necessary to drop the said cover or lid from its horizontal position in FIGS. 1 and 4 to the dot and dash position thereof in FIG. 4, and which second position is identified by the numeral 72. In order to drop the said cover or lid 16 the supporting side straps 66 and 67 are each formed in two pieces with the adjacent ends of the pieces connected to one another through a well-known snap fastener 73 and whereby the said lid or cover may be readily arranged in either of its positions in said FIG. 4.

From the foregoing it is believed now evident that there has been provided a cooler for containers, such as kegs, in which beverages of the pressurized type, are contained for dispensing therefrom into glasses, or other separate containers, and otherwise accomplishes the objects initialy set forth.
