8 Claims.

Thisinvention relates to insulated cabinets for refrigerating anddispensing liquids from relatively large containers I I It hasbeen found that it is much more efficient andeconomical to dispense liquids such as milk fromalargecanobviating the necessity of packaging or bottling the milkand for subsequently opening, said bottle or carton.

Our; Patent No. 2,377,261 discloses conventional cabinet andpi'nch cock valve mechanisms aswell as the novel milk can with a flexible tube fixed to. the bottom thereof topermit the milk to be drained from thescan throughsaid tube when the pinch-cock.valve is open. The departments of health in the various states have approved this general type of milk can and dispenser since the flexible tube is so designed as to requirecomplete replacement thereof and cannot be re-used. It has, however, been a difficult matter to produce a cabinet for refrigerating these large milk containers while permitting quick and easy insertion of the flexible tube through the pinchcock valve mechanism and while providing an effective seal around the peripheral marginal portion of the hinged cabinet closure.

I It is an object of our invention to provide a relatively simple yet highly efficient and ingenious cabinet and'valve mounting member which combines to facilitate insertion of the replacement flexibletube through the valve mechanism while producing ahighly effective seal with the flexible'sealing gasket on the hinged cabinet closure." I

I Itis another object to provide a valve mounting member adapted to be mounted adjacent the bottom of an insulated casing to permit a pinchcocktype of valve to be secured to the bottom portion thereof and provided with a removable closure plate for permitting substantially unrestricted' access to the valve chamber when said plate is removed but closing the front and top portion of said valve mounting member to provide a seal across the front edge of the cabinet bottom when the cabinet closure is closed thereagainst. y 1

I ;More specifically, it is an object to provide a cabinet having insulated sides, top, bottom and rear panels and an insulated front closure with a flexible sealing gasket peripherally mounted around themarginalportion thereof. .The front marginal portion of said cabinet bottom is depressed a substantial distance below the main bottom portion and is provided with a recess therein in which a valve mounting member is securely received,said valve mounting member being constructedwith a front access opening therein which isnormally closed by a removable closure plate which also extends inwardly across the top portion to closely embrace the tube extending downwardly through the valve mechanism. I

Still more specifically, it is an object to provide a valve mounting member having a pair of topflanges sloping downwardly toward the rear thereof and adapted to engage and cooperate with a 'rearwardly sloping top surface of the depression formed in the front marginal portion of the cabinetbottom'to hold said mounting member against forward shifting movement when said flanges are clamped tightly downwardly against said sloping depression.

These and otherobjects and advantages of the invention will more fully appear from the following description made in connection with the accompanying drawings, wherein like reference characters refer to the same or similar parts throughout the several views; and in which Fig. 1 is a front perspective view of our improved insulated" cabinet I and valve mounting member showing the door in open position;

position in the cabinet; I

I Fig. 4 is a front elevational view of only the valve mounting member; and I r top closure sections thereof.

As best shown in Fig. 1 we provide a cabinet having insulated sides I and B, an insulated back panel 9 and top panel 10., An insulated bottom H interconnects intermediate portions of the sides and back panel forming an insulated compartment disposed in spaced relation above the lowerextremities of the sides and back. The front marginalportion of said bottom II has a depressed step Ila. in which the top surface thereof slopes downwardly toward the rear thereof and in which the bottom surface of said step Ila also slopes downwardly toward the rear hinged along one edge to the side 8, to be sealed thereagainst as by the compressible gasket-elements l3 fixed aroundtheperipheral marginal ber l5.

edge portion of the inner surface of said door l2. An upstanding gasket element l3a is fixed along the hinge member and forms the seal along the front edge of side A latch mechanism it is pivotally mounted on the side 7 and engages a projection i5 fixed on the free edge of the door l2 to securely lock the same in closed position.

The compartments may be refrigerated by any conventional refrigeration system, not shown, and adapted to be positioned under the bottom II and enclosed by the downwardly extending sides and back panel. A front closure skirt l2a conceals the refrigeration mechanism from the front and extends across between the downwardly extending side portions.

The front edge of the step Ila has a recess formed therein to receive a valve mounting mem- This valve mounting member I6 has a curved rear wall which is inclined forwardly toward the bottom thereof and the rear of the recess is shaped to conform thereto. A retaining and supporting peripheral flange I! is mounted around the upper portion of said valve mounting member and slopes downwardly toward the rear thereof so that the two front edge portions of said flange are disposed substantially adjacent the horizontally disposed top edge 16a of said mounting member while the rear curved portion thereof is disposed a substantial distance below said top edge. The slope of this peripheral flange is designed to conform to the slope of the inclined step Ha and to engage against the top portion thereof surrounding said recess. A pair of vertically disposed front flanges 18 extend downwardly from the top front edge of flange l1 and have an access opening formed therebetween. A bottom flange l9 interconnects the lower extremities of said front flanges 18. The lower portion of the valve mounting member It has a tubular shankv 20, in'the, form shown integrally formed therewith. Thisidepending shank 20 has a threaded upper portion 2| and has an annular set screw receiving keyway 22 formed a short distance above the lower extremity thereof.

The valve mounting member is initially inserted into the recess formed in the step Ila as best shown in Fig. 3 and thereafter a clamping nut 23 is threadably mounted on the threaded portion 2| of the shank 20 and drawn up tightly against the sloping bottom surface of the step Ila, also as best shown in Fig. 3. A pinch-cock valve assembly designated as an entirety by the numeral 24 is mounted on the lower portion of the tubular shank 20 and is secured thereto as by a set screw 25, best shown in Fig. l. The clamping lever 26 of the valve is pivoted on pin 21; A weight 28 holds the clamping end of lever in tightly clamped closed position.

A relatively large container such as the milk can 29 is mounted in the refrigerated compartment and this container 29 is provided with a discharge sleeve 29a best shown in Fig. 3 and formed in the bottom thereof. A flexible tube 30 is connected to said sleeve 29a and is sealingly plugged at the free end thereof to retain the liquid in the container 29 before the tube is mounted in the pinch-cock valve assembly. The tube is easily inserted through the valve mount ing member by the provision of the open slot between the front flanges l8 and when the valve lever 26 is raised the tube is pushed down through the tubular shank 20 as best shown in Fig. 3.

The lever26 is then released and the plugged end portion of the tube 30 is cut off as disclosed in my foregoing identified patent.

The rear portion of the open top of said valve mounting member I6 is closed by a closure section 3| having a peripheral flange 3la extending around the entire rear portion thereof and having a pair of front retaining hooks 3lb formed at the outer front portions thereof. A tube receiving recess 3 lo is formed in the upper cover portion thereof and closely embraces the tube 30 as best shown in Fig. 3. A pair of retaining dogs 32 are formed on intermediate portions of the sides of top [6a. to receive the hooks 32h thereunder and retain the closure section 3! in closure position. A removable front closure section 33 is adapted to be received against the front flanges l3 and I9 and has a tube receiving recess 33a formed in the rear edge portion thereof to combine with the recess 3m to closely embrace the entire periphery of tube 30 a short distance below the bottom of the container 23 and to maintain the same in clean sanitary condition. The extreme front top edge of the valve mounting member is has a pair of upwardly extending projections 34 best shown in Figs. 3 and 5 and the section 33 has a cooperating recess 33b adapted to'receive said projections 34 and combine with a flange receiving hook portion 330 formed in the bottom of said section 33 and adapted to receive the lower edge of bottom flange l9, to hold said section 33 in closed position across the front face of the upper portion'of said mounting member 6 and the forward portion of the top thereof. This front closure section 33 is, of course, easily removable whenever a new container 29 is to be installed within the chamber of the cabinet and is made of any'suitable material such as spring steel topermit the same to be repeatedly used.

It will be seen that we have provided an extremely ingenious cabinet and mounting member for simplifying and greatly facilitating the replacement of containers within the refrigerated compartment of the cabinet, as well as permitting.

a tight seal to be formed around the marginal periphery portion of the cabinet door [2. The opening provided when the front closure section 33 is removed greatly facilitates insertion of the flexible tube 30 into the shank 20 through the valve mechanism 24 by providing a relatively great accessibility thereto. When the closure section 33 is replaced across the front face of the mounting member i6 aflat surface is provided across the entire frontedge of the step [Ia and a tight seal is permitted around the entire peripheral marginal portion of the door l2. The closure section 33 is the same width as the distance from the extreme edges'of the flanges l3 and completely covers the front surfaces of said flanges, as best shown in Fig. 4. 7 It should be noted that the two cover sections 3| and 33 closely embrace a medial portion of the flexible tube 30 and provides a substantially dead air space surrounding said tube to eliminate a large portion of the heat loss experienced in previous structures. x

It will, of course, be understood that various changes may be made in the form, details, arrangement and proportions'of the various parts without departure from the scope of the present invention, which, generally stated, consists in the matter shown, and described, and set forth in the appended claims.
