A further object ot 'theiinventlon' is to 'provide a c n a er th f h'mt r' t p 'wh 'c may be 'made cheaplyffand which "will be *suiliciently rugged to be us'emrm "the shipping and storage r'oi! beverages f such "as beer; milk and the i 1 Y I it I i .1""
Other objects and advantagesof the'inven'tion will be apparent from theftollowing detailed descriptiomftaken' in connection with thew epipanying emwmgs; wherein Ihave shownthe pre- Referring'tothe drawlngs: A, j I Fig; 1 is'a vertical section] through a 'doub1e jalled container constructed'in accordance with the invention; and" plated' applying fthe pnmipms of the 'inv'eiitioh.
' Fig. 2 isa broken vertlcalsection through -the 'containen theview showing the-oppositehalves head-wall! and thezupper halt oilside wall I being formed by a stamping operation from a single r piece of sheet metal, and the lower hall. of the vessel beingv similarly. formed, the halves being then welded together as indicated at' 5 I tovtorm afluid-tlght'receptacie. 1
' "Receptacle [is enclosedin anouterreceptazile designated generally by .thenumeral 8,;said outer receptacle. consisting of: upper and lower head walls sand-"l0; respectively and aside wall ii 10 connecting -said head walls.to form a .-.barrel:- shaped vessel corresponding in shape? to themher receptacle 3. -The=walls. ofthis I outer: containet are also formed of. sheet': metal; thehead walls being I form'edintegrally with the opposite l5 halves'oiaside -wall iipsaid opposite halves being then" assembled" and welded as indicated at l2. The outer head walls 9 and ID are formed toiprovide "beads "or flanges i3 which extend -.outwardly from said headwalls to provide rims for protect- 20 *ing the latter." A filling bung ring l4 isweldedto therim 'portion oi! a filling opening-i5 i'ormed in the inner'receptacle't' showntiriFlg. 2,-this ringex'tends through opening-I6 formed in wall or the outer receptacle.-.;A.=collar YH, 85 formed of heat insulating" material, andtzhavinga circumferential groove l8 formed therein: for receiving the rim portion of opening- 16, insulates bung lring i4=-trom sidewall I in! the outer receptacle. A shoulder: i9,;1ormedlon ring i4, en- 80 gages collar i'l, thelatter being held in place bya metal washer 12 i I which. is welded; tov ring I4- after-{the parts have been assembledain a manner presently to Abe explained. iAll metallic :con'tact betweenrlng l4-'andwall: l'llis thuspre- 35 vented through the'provision oi! insulating collar l1, thereby. eliminating a direct'path'i'Qr conducuts 01 heat mm wall 'Il through ring 14- to Y a tap mung ring 22 apt-eves "inane ad wens 4 and-'9,';said ring being welded into inner head wall 4 and insulated from outer'he'ad wall 9 by a" collar 23 which is formed 'ofinsulating 1 material, said collar-being provided 'with a circumferentialgroove 24101 receivingtheportion of *head wall I which formsithe rim oi anigpening v251-formed'therein1or receiving ring 2);" Collar 23'abuts against a shoulder26 formed on ring 22, and a washer 21, formed of insulating material, fits over collar 23 to lap the rim 0! opening 25 after the parts have been assembled in a manner which will presently be explained. A metal washer 29 is welded to the outer end of ring 22 and serves to hold collar-23 and washer 21 in anchored position on ring 22. All metallic contact between head ring 22 and wall 9 is thus prevented through the provision of insulating collar 23 and washer 21, thereby eliminating direct conduction of heat from wall 9 through ring 22 to wall 4.
In accordance with my invention, means is provided for insulating inner receptacle 3 to prevent conduction and radiation of heat thereto through outerreceptacle 8. My emperiments have shown- 10 that provision of a mass of non-conductive heat insulating material in the space between the inner and outer receptacle walls does not serveto completely prevent transmission of heat to the inner receptacle, this being due to the fact that a very substantial amount of heat is transmitted by radiation and conductance to the walls of the inner receptacle. I have discovered, however, that by using a reflective insulating material, in combination with a mass ofnon-conductive insulating material and by eliminating all metallic connections between the inner receptacle and the outer receptacle, I am able to almost' between top head walls I and- 9, and bottom head walls 5 and Ill. Any suitable non-conductive heat insulating material such as cork, fibre, felt, hair, magnesia and mineral wool, may be used for this purpose. This body of insulating material 3| serves both as an insulating medium, and also as a means for rigidly holding the receptacles in proper spaced relation. I have found that the latter function may be best performed by molding the insulating material to the desired lllshape. If necessary, a small amount of a suitable binder, such as glue, may be incorporated with the mass to render it suitable for molding. In the molding operation the mass is compressed to give it the necessary density and strength to serve as a spacer for preventing contact between the inner and outer' receptacles. By using a molded insulator it is unnecessary to provide reinforcing and spacing ribs to hold the two receptacles in proper spaced relation. The elimi- 59 nation of such ribs, of course, avoids direct metallic contact between the inner and outer receptacle walls, and thereby minimizes conduction of heat to the inner receptacle.
The reflective heat insulating material which is used in combination with the non-conductive material 3| comprises a thin layer or sheet of polished metal which is interposed between the mass 3| and the adjacent walls of receptacles 3 and 8. A sheet of metal foil 32 is interposed between the mass 3| and walls 9, llland ll of the outer receptacle, and a similar sheet of metal foil 33 is interposed between mass it and walls 4, 5 and 6 'of the inner receptacle. Any polished metal foil or thin sheet metal having heat reflective properties may be used t form the sheets 32 and 33. I prefer to use the reflective sheets between the mass and the walls of both the inner and outer receptacles, however, if preferred, one or the other of the sheets 22, 33 may be omitted, the insulator being employed on only one side of the mass 3|. Also, it may be desired to employ a thin sheet of reflective material in the form of an electro-plate deposited. either on the inner surface of the walls of the outer receptacle or on the outer surface of the walls of the inner receptacle, and the use of a reflective material in this manner is considered to be fully within the scope of the invention.
In Fig. 2 I have shown the sequence of steps or operations involved in building up the double walled unit from the half sections of the inner and outer receptacles. The inner receptacle 2 is first made up by welding together the opposite halves thereof as indicated at 1, after which bung rings l4 and 22 are placed in position and welded. The opposite halves of the mass of insulating material 3!, which have been prelimi-- narily molded to shape, and to which sheets 22 and 33 of reflective insulator have been applied, are then placed in position over the opposite ends of the inner receptacle. These molded sections are formed with suitable openings 34 and 3' for receiving rings l4 and 22 respectively. The half sections of the outer receptacle 8 are then placed 1 over the opposed halves of the insulating mass 3 I and the composite half sections are then compressed or forced together over the. ends of theinner receptacle, insulation collars l1 and .22 having been preliminarily placed. in position on ringsl4 and 22, respectively. After the parts have come into abutting relation the opposite halves of the outer receptacle are welded together asindicated at 12, and washers 2| and 2! are then; welded-to the outer ends of rings 14 and 22, re---- spectively,.to complete the unit.
The foregoing detailed description bun given for cleamess of understandingeonlmand. no unnecessary limitations should be understood; therefrom, but the appended claims should--be' construed as broadly as permissible in view ofthe prior art.
What I regard as new and desire to-secure by Letters Patent is:
1. A tap structurefor a double walled receptacle comprising a tubular body secured! the wall of the inner receptacle around the tap opening therein, said body projecting from the inner. receptacle through the wall of the outer receptacle and having a perimetrical channel formed therein for receiving the marginal walls of the tap opening in the outer receptacle, and a mass of heat insulating material disposed in said 'channel between said body and the walls of the outer container.
2. In a double walled sheet-metalreceptacle, a tap structure comprising a metal sleeve secured at its inner end to the wall of the inner receptacle around the tap opening therein, the outer end of said sleeve projecting through the wall of the outer receptacle and the body of said sleeve being cut away to receive the marginal walls of the tap. opening in the outer container, and a body of heat insulating material disposed in the cut away-- portion of said sleeve, said material being'anranged to prevent all metallic contact between said sleeve and the adjacent wall of the outer container.
