CHAMBERED MILK CAN WITH THERMO-PLASTIC INSERTABLE COVER PLATE Filed Dec. 14, 1959 United States Patent ()fiflce Patented Aug. 21, 1952 3,056,216 CHAMBERED MILK CAN WETH THERMO-PLASTIC INSERTABLE CQVER PLATE Lannie F. Norris, Minneapolis, Minn, assignor to Norris Dispensers, Inc., Minneapolis, Minn, a corporation of Minnesota Filed Dec. 14, 1959, Ser. No. 859,202 8 Claims. (Cl. 222184) This invention relates to bulk liquid containers and more specifically to a bulk liquid container of the type having a tube enclosing compartment and having a disposable plastic cover for closing the tube enclosing compartment.
An object of the present invention is to provide a novel bulk liquid container for use with refrigerated sanitary dispensing apparatus and including a tube enclosing compartment closed by a novel disposable plastic closure member having means for positioning and retaining the same in sealing relation with the compartment.
Another object of this invention is the provision in a bulk liquid container, of the type used with refrigerated dispensing apparatus and including an integral tube enclosing compartment, with a disposable plastic closure member for sealingly closing the compartment and being formed of frangible material to permit ready breaking thereof.
A more specific object of this invention is to provide a novel disposable plastic closure cap for closing a tube enclosing compartment of a bulk liquid container and in which the closure cap includes means for assuring proper positioning thereof in sealing relation with the compartment to thereby prevent contamination of the compartment.
These and other objects and advantages of this 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 perspective view of a bulk liquid container embodying the present invention;
FIG. 2 is a fragmentary front elevational view of the container shown in FIG. 1 with the sealing closure cap removed showing the elongated flexible tube contained within the protective chamber formed by the closing shell P;
FIG. 3 is a vertical sectional view showing the lower portion of the bulk liquid container in operative position within a dispensing cabinet;
FIG. 4 is an enlarged vertical section taken on line 44 of FIG. 1 and looking in the direction of the arrows; and
FIG. 5 is an enlarged perspective view of the novel closure cap member.
Referring now to the drawings and more specifically to FIG. 1, it will be seen that one embodiment of this invention may include a container such as a milk can 8 having a relatively large upper mouth portion 9 which is closed by a conventional top cover 10. Container 8 is also provided with conventional carrying handles 11, only one of which is shown in FIG. 1. Container 8 is in the form of a cylinder and includes circumferential walls 12 which extend downwardly from the handle band 811 to the bottom of the container. The bottom 13 of container 8 is provided with an upstanding peripheral flange 13a and the bottom 13 is inserted into the cylinder 12 forming the circumferential walls and is positioned a substantial distance from the lower end of the circumferential Walls as best seen in FIG. 1. A reinforcing bottom band is then pressed into the lower marginal portion of the cylindrical circumferential walls 12 below the container bottom 13 and is secured in place by any suitable means. Container bottom 13 is then securely fixed to the inner circumferential surfaces of cylindrical walls 12 as by electrically welding the upstanding flanged portion 13a thereto. A pressure well is produced which molds the peripheral flange 13a and adjacent irmer circumferential surface of cylindrical wall portions together and permits a subsequent bufling operation to produce a completely smooth joint therebetween.
A recess is then formed in the base flange or skirt of the container by deforming a portion thereof a substantial distance inwardly to provide a depression having a shellreceiving opening formed therein and the portion surrounding the opening or aperture lying in an inclined plane sloping downwardly and inwardly towards the container center. The depression designated by reference numeral 14 and the portion of the base flange surrounding the aperture is designated by the reference numeral 15 as best seen in H6. 3.
Referring now to FIG. 3, it will be seen that the cont ainer bottom 13 is provided with an aperture 16 and a slightly downwardly depressed portion 16:: surrounding the aperture to define a small collector basin. A shell or cup member 17 is inserted into the aperture formed in the depression 14 of the base flange and is provided with a peripheral flange 13 surrounding the mouth opening 19 thereof. Shell member 17 is also provided with an aperture 26 in the top portion thereof and which is adapted to surround the depressed portion 16a formed in the container bottom 13 and is slightly larger than the aperture 16 formed at the bottom of the depressed portion 16a.
Referring now to FIGS. 2 and 3, it will be seen that mouth opening 19 includes a peripheral edge 21 with the lower portion thereof being flattened or straight as at 22. This straight edge portion 22 of peripheral edge 21 has an upwardly projecting retaining lip 23 extending upwardly from the inner edge of flange 18. The upper portion of peripheral edge 21 is provided with a pair of depending tab elements 24 which extend towards and are disposed in opposed relation to lip 23. The function of lip 23 and tabs 24 will be described hereinbelow.
A discharge tube attachment nipple 25 is fixed in opening 16 as by welding to the portion of container bottom 13 surrounding opening 16 and the upper end of nipple 25 is disposed adjacent the bottom of recess portion 16a. Referring again to FIG. 3 and FIG. 4, it will be seen that nipple 25 is inclined slightly from the vertical with its lower end disposed outwardly from its upper end and is adapted to receive in sealed relation thereon a flexible discharge tube 26. The lower end of nipple 25 has a bayonet enlargement formed therearound which, of course, serves to securely hold the upper end of flexible tube 26 thereon. It is also pointed out that prior to the mounting of flexible tube 26 on nipple 25, the entire container 10 is tinned in the conventional manner and the tinning material forms a smooth coating on the surfaces of all the parts so that the interior of shell member 17 is smoothly contoured to thereby permit easy and complete cleaning thereof.
When container 8 is prepared for use, it is first sterilized and a discharge tube 26 is mounted on the nipple 25 and the lower end of the discharge tube is sealed by a plug member which is secured therein. Referring now to FIG. 3, it will be seen that container 8 is arranged for the operation of dispensing liquid therefrom and requires the plugged end of discharge tube 26 to be severed which, of
course, destroys the tube for subsequent use. After the discharge tube 26 is mounted on nipple 2-5, container 8 is then filled with liquid such as milk and the flexible tube 26 is folded and inserted into the compartment defined by the shell member 17 as best seen in FIG. 2.
A uniquely constructed closure cap member generally designated as 27 is provided for closing mouth opening 19 in sealing relationship to thereby prevent contamination of the interior or compartment defined by shell member 17. Cap member 27 is formed as by molding of a resilient but rigid frangible thermo-plastic material to permit ready breaking thereof when it is desirable to place the container 8 in an operative liquid dispensing condition.
Referring now to FIG. 5, it will be seen that cap member 27 is provided with a pair of laterally spaced guide members 30 affixed to inner face 28 and which engage inner opposed surface portions of shell member 17. It will be seen that cap member 27' is of a shape and size to have marginal portions thereof engaging the peripheral edge 21 of mouth opening 19 in sealing relation when the cap mem ber is disposed in mouth closing position.
A pair of spaced apart lip engaging elements 31 are affixed to the inner face 28 of cap member 27 and have lower edges 32 which are inclined with respect to the inner face and cooperatively engage lip 23 of peripheral flange 21 when the cap is in mouth-closing relation. Lip engaging elements extend transversely of the inner face 28 of cap member 27 to thereby define reinforcing portions 31a which serve to impart rigidity to the cap member. Since the cap member 27 is somewhat resilient, the reinforcing portions impart sufficient rigidity thereto which facilitiates breaking of the cap member.
When the cap member is positioned in mouth closing relation, the upper portion thereof is positioned inside tabs 24 while guide members 30 engage inner opposed surfaces of shell member 17 and thereby serve to properly position the cap member against the peripheral edge of the mouth opening. The'lower portion of the cap member is then urged inwardly and lip engaging elements 31 are cammed or snapped behind and retained by lips 23. Thus the interlocking relation of lip engaging elements 31 with lips 23 and interlocking relation of the upper portion of the cap member and tabs cooperatively retain the cap member in mouth closing relation. The marginal portions of the cap member 27 are therefore urged into sealing relation with the peripheral edge 21 of mouth opening 19 so that the interior of shell member 17 along with discharge tube 26 are sealed from the outside thus preventing contamination thereof. Since the cap member 27 is formed of a frangible material, it can be readily broken or ruptured thus requiring no tools for removal thereof.
When container 8 is put into a refrigerated cabinet such as cabinet 33 shown in 'FIG. 3, the closure door 34 of the cabinet 33 is opened and the container is positioned within the cabinet with the base flange 31 supported on the bottom 35' thereof. Cap member 27 is then removed to unseal the compartment formed within shell 17 to permit the tube 26 to be removed from the compartment and inserted downwardly through a tubular valve mounting member 36. Tubular Valve mounting member 36 is provided with a valve 37 having a pinch-cock 38 which closes the tube 26 by pinching the same. The lower end of the tube is then cut off and the tube, of course, is destroyed for subsequent use. Removal of the cap member 27 may be accomplished by breaking the same since the reinforcing portions 31a impart rigidity to the resilient frangible material to permit ready breaking thereof. Of course, cap 27 may also be removed withoutbreaking the member but since the cap is disposable and is formed of frangible material, breaking thereof is the preferred manner of removal.
It will be seen from the foregoing description that I have provided a .novel bulk liquid container having a depressed portion in the lower flange thereof in which a shell member is mounted for completely enclosing a flexible tube communicating with the interior of the container. It will also be seen from the preceding paragraphs that the tube enclosing shell member defines a smoothly contoured compartment to permit ready cleaning and sterilizing thereof and which is sealingly closed by a novel disposable closure cap member in a manner to preclude or greatly minimize contamination of the interior of the compartment. It will also be noted that the novel closure cap is formed of frangible plastic material to permit ready breaking thereof and is arranged and constructed to cooperatively engage the shell member to insure proper seating of the cap member in sealing relation with the shell member. It will further be noted that the novel disposable closure cap includes retaining means arranged and constructed to be interlocked to the tube enclosing shell member whereby the closure cap is positively retained in mouth sealing relation with respect to the shell member.
Thus it will be seen that the tube-enclosing shell of the bulk liquid container is sealingly closed by a uniquely constructed closure member which may be readily applied by a simple operation and which may be readily removed by breaking of the same.
It will, of course, be understood that various changes may be made in the form, details, arrangement and proportions of the parts without departing from the scope of this invention which consists of the matter shown and described herein and set forth in the appended claims.
