To all whom 'it may concern.'

'This invention relates to insulated milk cans. v

An object of the invention is to provide an improved construction of can of this character including an outer` double walled jacket filled with insulating material and an inner vessel of glass, porcelain,. china, or

other non-corrosive material, th e. insulating 'jacket embodying separable sections so arranged with respect to each other and with the inner vessel as to insure against movei ment of theinnervessel longitudinally in Yso the jacket.

In the drawings, forming a portion of this specification and in which like numerals of` reference indicate similar parts in theseveral views:-Figure 1 is a vertical section through myimproved can. Fig. 2 is an enlarged view through a portion ol. the same.

vFig. ,3 is a horizontal section on line 3-3 0f Fig. 1. I ig. flis :i view similar to Fig. 1 showing the funnel attachment applied to the neck of the inner vessel.

The can comprises an outer ii'isulatinf T i jacket 1 and an inner vessel 2, which latter preferably constructed of glass, porcelain.

china, or other non-corrosive inateri al.- The insulating jacket includes a lower section 3 and au upper section t which are detachably connected with eachother as will be hereinafter fully explained. 'The lower section embodies an outer wall 5 and an inner wall.

6. The bottom of the inner walll is disposed above the plane of the bottom of the outer jwall yandvcmhracing the sameexteriorly is the flange 7 o'l" an inner bottom .member 8.

`An outer bottom member S) is located beneath the bottom 8 and in spaced relation thereto and it is f'o'rmed with a depending l outer flange 10 which is embraced by the lower yend of the wall The lower end of the lwall-5 is embraced by an exterior clamp- A.ing band 11. The flange 10 embraces an innerclamping- -band 12. The hands 11 and `12 and the flange 10 are secured to the lower end of the wall 5 by rivets 13. rlhe upper end of the outer wall 5 is disposed below thel plane of the upper end ol'` the wall 6, and as illustrated, it is offset inwardly so as to form a peripheral recess 14. Atsubstantially stepped member connects the Walls' 5 and 6 with each other. This member is provided with the upper and lower vertical flanges 15 and4 16 and an intermediate vertical flange 17. The flange 15. is secured to the wall 6', at 18. The lower flange 161cx tends into the recess 14 and is secured to the offset portion of the wall 5, by rivets 19. An exteriorly threaded ring 20 embraces the flange 15 and is secured thereto by the rivets 18. A similar exteriorly threaded ring 21 is secured by rivets to.the flange 17. In addition to the

rivets

18 and 19 which secures the step ed connecting member with the walls 5 an 6, solder may be used so as to form a perfect air tight joint.

The top section 4 of the insulating jacket includes an inner wall 23 and an outer"wall 24. These walls are connected with each other by the member 2.). This member is stepped and is substai'itially of identical configuration with the hereinbefore describedl stepped connecting member, and as shown,

it is provided with the veltical flanges 26 and Q7 and the horizontal flanges Q8 and 29. An attaching flange 30 is formed on the member Q5 at the upper end thereof and secured by rivets 31 to the lower edge of the wall 23. The vertical flange .26 of the member is secured by rivets 32 to the Wall 24.

This` wallQfl is formed to provide a horizontal shoulder which is designed to rest upon the 'lower horizontal wall 34 of the stepped connecting member hereinbefore described as connecting the

walls

5 and 6 with each other. The flange 26 has secured thereto 'an interior-ly threaded ring 35 which is designed for attachment to the ring 21 so as to securely hold the sections fl and 5 closed against each other.V The wall 93 has secured thereto a vertical collar 36 which is spaced throughout from a similar collar 37 which is secured to the wall Q4. The collar 37 is closed at its top by a cover 38 which is spaced 'from a similar cover 39 which closes the collar 36 at its upper end. The cover 38 is provided with an outwardly flared flange 40 liaviug a circumferential reinforcing bead 41.

The inner vessel .2- is provided adjacent to its upper end with au external shoulder 42. A retaining device 43 is interiorly threaded for adjustment on the ring 20. This device is provided with a series of radial fingers 44 which are designed to engage the shoulder ioe ymembers 8 and 9.

l2 of the liner so as to hold the liner against.-

the top or breast of the inner vessel, as

shown in Fig. l.

The neck of the inner vessel is extcriorly screw-threaded and detachably fit-ted thereto is a cover 46. .et paper disk 47 is located on 'the imderside of the cover which is held against the neck of the inner' vessel when the cover is in its closed position. corel' is provided with a suitable handle 4%. The cover plate 89 of the collar 36 is spaced from the cove' 46 oit the inner vessel so as to 'forni a dead air space 49 therebetween. .Au insulatingl material of mineral wool, iyood, asbestos, or any other suitable nonheat conducting' body is placed in the space between the Walls and Gand between the walls and 24 and also between the

closure members

38 and 39 and between the ljigottom The bottom 9 1s provided With an exhaust opening by means of which the air can be exhausted from the insulating material and from the space between the

Walls

5 and 6 and the bottom members S and 9. A similar opening 51 is formed in the closure member 39 so that the air may be exhausted from the space between the walls 23` and 24 and the

members

38 and 3 rlfhe openings 50 and 5l are sealed by the 'plugs 52 after the air has been exhausted. A supporting member 53 is secured at 54 to the bottom member 8.' This member 53 contacts with the bottom 9 and securely braces the member 8. The member 53 is lsuitably perforated 'at 55 so as to permit the air to be exhausted from Vthe space between the .respective Wallsot the jacket.

A. reinforcing band 56 embraces the wall 5 near the upper end thereof. This band has attachingplates 57 secured thereto and supported by' the plates are handles Eyes 59 and 50 are secured to the sections oi' the insulating jacket and they are connected with each other by a seal Gl. lt will` be understood th/at this seal is applied after the inner vessel is placed in the jacket for shipment. f

To facilitate filling the inner vessel in a sanitary manner or to enable one to pour out its contents Without spillingr the same, l. provide the iunnel attachment GQ. This attachment includes an inner yglass funnel 63 and an outer metal funnel (il. The inner funnel islprovided with an extcriorly threaded neck to which the interiorly threaded neck 6G tot the outer funnel (34C is engaged. ythe length ot' the neck 6G exceeds thaty of the neckt so that a threaded portion 67 of This the neck 66 extends below the plane of the lower end of the neck 65. This portion 67 may be engaged with the exteriorly threaded ncck of the inner vessel. as shown in Fig.' 4. From this construction it will be seen th'at the contents of the inner vessel can be poured without the contents coming in contact with any metal parts, it being an essential object in acan of the characterdescribed for the reason that it has been found from experience that germs or foreign matter will adhere to metal parts and are frequently transferred from one vessel to the other in the pouring operation. The insulating` material which is arranged between the Walls of the insulatingjacket is provided solely for the purpose of preventing the rapid absorption of heat should the outer wall of the jacket become punctured in transit.

I claimzl. In a heat insulated'can, an insulating jacket including inner and outer Walls, the

inner Walls beingextended above the plane of thel outer Walls, a stepped member connectinpthe inner and outer walls together at their upper ends, an inner vessel embraced by the inner walls and having an eX- ternal shoulder occupying substantially the same general plane with the upper end of the said inner walls7 adjustable means on the stepped member having portions extending;a Within the inner Walls and engaging the shoulder of the inner vessel, the said'connecting member 'spacing' the inner and outer walls from each other. a bottom for the outer walls, a bottom for the inner Walls, means interposed between the first and second named bottoms tor spacing them from each other, and aV closure section adjustable on the stepped member and having'a inner and outer walls and provided with a horizontal flange which engages the inner vessel engaging means when said closure section is closed upon the said stepped member.
