Patented July 2'?, 1915.

Application led October 25, 1913. Serial No. 797,290.

To Z7 1li/:om it may concern .lie it known that l, LEONARD R. STEEL, a eitizenlof the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Shipping-Cans, of which the following is a specification.

This invention relates to shipping cans; and it has for its primary object the provision of a structure of this character which will effectually serve to retain the contents of the can at a practically uniform temperature for a considerable period of time.

Another object of the invention is the provision of a structure of this character which will include an outer vessel of separable sections, an inner vessel removably fitted in the outer vessel, and an intermediate lining of insulating material between the inner and outer vessels and arranged to wholly embrace or completely jacket the inner vessel t0 protect the .same from the outside air.

Another object of the invention is the provision of a structure of this character which will be formed of separable sections that are adapted to he readily separated as the occasion may demand and treated to a sterilizing bath and maintained in a highly sanitaryY condition.

A further object 0f the invention is the provision of a can including an outer sectional vessel having a removable cover and an inner lining of insulated material associated with the walls of the outer vessel in such manner as will prevent certain sections of thelining from separating when the structure is canted.

A further object of the invention is the provision of a structure of this character which will include an outer vessel of separable sections and a cover section and means between the separable sections and the cover section for sealing the latter to prevent tampering with the contents of the can without detection.

Vith these and other objects in View, thel invention consists-of certain novel features of construction, combination and arrangement of parts, as will be hereinafter described and claimed.-

in the accompany-*ing drawings z-Figure l is a side view of the cang-Fig. 2 is a Ver tical section therethrough; Fig. 3 is a horizontal section taken on the line 3 3 of Fig. 2; Fig. i is a perspective view on a reduced sure section i. The lower section'2 is closedr bv a bottom member 5, which is disposed abovethe lower edges of said lower member and provided with a depending outer flange which is embraced by the lower walls of said section 2. Embracing the lower walls of the section 2 and secured thereto and to the flange G by means of rivets 7 is a rei iuforcing ring 8 formed preferably of iiat sheet metal and designed to coperatie in the purpose of the flange G to sufficiently strengthen the bottom of the can and prevent the same from being injured While in transit.

At the upper end the section 2 is embraced b v an annulus 9 riveted to said section, as at 10, and then offset at 11 to overlie the upper edge of said section and then terminally formed to provide a vertical annular iiange il, the latter having diametrieally-disposed fixed threaded studs 12 provided at their outer ends with stop projections 14. rThe breast section 3 has riveted thereto, as at 15, an annulus 16 having diametrically-disposed bayonet slots. 17 whose vertical branches 18 are adapted to initially receive the studs 12, while the horizontal branches 19 of said slots are adapted to subsequently receive the studs when the breast section is rotated, slightly upon the lower section 2. After the sections 2 and 3 have been rotated relatively for the purpose just mentioned, adjusting nuts 20 on the studs may be brought to bear against the annulus 16, and, as a consequence thereof, the studs will be held against accidentally working,r into the vertical branches 18 of said bayonet slots 17, and the sections 2 and 3 held operatively connected with each other.

The breast section 3 is of cylindrical form at its base and from the base said section is gradually curved inwardly at 2l and finally the walls of the section are extended into a vertical flange 22. rl`his flange is embraced b v the depending llange Il ot'aclosurc biectiou 2l. the latter having a crown 25 which tornis a seal to completely cover the inner vessel 2li. Y

'lhe inner vessel to may be constructed of glassporcelain. metal lined with porcelain or any other suitable well known material, and it is preferably provided with a cylindrical body 2T whose walls are merged into a curved breast' 25. rl`he walls ol the breast s lie parallel with the curved walls 21 lorniing the breast ot the section 3 of the outer vessel. '.l`he walls of the breast Q8 are extended into the vertical neck 29 which terminates slightly beyond the outer edge of the flange 22 ot' the. outer vessel in order that the contents of the inner 4vessel may-be poured l'roin the can without said liange 22 forming an obstruction. 'lhe neck 29 of said inner vessel is exteriorlv threaded at :iu to receive a correspondingly threaded [lange 31 ol' a closure 32. This closure carries a lived handle 33 which is adapted to be grasped bv the hand and manipulated in order to eli'ect adjustirent oi the closure onto or ollA of the neck 29, as will be understood ln order t'o prevent the liquid within the vessel :2G i'rom contacting with the metal ot' the closure I preferably provide the latter with an inner disk 34.

lnteiposed between thc inner vessel 26 and the outer vessel 1 is a lining of insulating material which consists of a base section 34 having a bottom 35 interposed between the bottoni 5 oi the outer vessel and the bottoni 3G oi' the inner vessel and at a point below the upper end of the section 2 of the outer vessel the said section 34 of the insulated lining is provided with a stepped portion 3T, which lits a correspondingly stepped portion 38 of au upper breast section 39 of the lining. It is preferred that the upper end of the section 34 of the lining terminates below the upper end of the section 2 of the outer vessel in order that the walls als of'the section 39 of the lining will lap the joint between the sections 2 and 3 of the outer vessel and thereby minimize the possibility ot the. outside air entering within the lining. as will be understood. The br xast section 3f) terminates in a short vertical llange 40 which embraces the neck 29 of the inner vessel, and which is preferably spaced therefrom. Said flange 40 terminates below the outer end of the neck 29 so that the latter will be exposed sufticiently tlwrebeyond to permit the contents of the inner vessel to be poured without said flange l0 forming an obstruction. The insulated lining is completed by a closure section 41 of insulating material having a flange 42 which extends around the neck of the inner vessel and which embraces the fiange 40 of the breast section 39 of the lining. Said fiange 42 is provided with a beveled lower surface 43 which is adapted to rest against the adjacent outer surface 44 of the breast section.

In order to prevent the contents of the inner vessel 2G from being removed from the .an without detection, I lprovide the studs 12 with passages 45. while the flange 23 of the closure 4 is provided with staples 46 that are arranged to mate with the passages 45 and to receive therewith suitable sealing wires 47. In this manner, it is seen that if thc cover 4 is rotated on the outer vessel, said sealing wires will be broken. The cover 4 is provided with an opening 48, in which one end of a chain 49 is connected, the opposite end of the chain having connection with one side ot' the breast section 3 of the outer vessel, as at 50. ln this manner loss of the cover 4 from the section 3 is prevented.

The closure section 41 is provided at its lower end with an exterior-ly arranged reduced portion 42 adapted to receive the vertical upstanding flange 22 of the breast section oi the outer vessel. lt will be noted that by this arrangement, the vertically extending flange 22 is substantially flush with the periphery ot they section 4l. thereby preventing any bulging eti'ect of the flange closure 4 when in active position.

From the construction described. it is seenl that in filling theinner vessel 2G the cover 4 of the outer vessel may be removed together with the cover section 41 of the lining so as to fully expose, the neck end of said inner vessel. Said neck end preferably has a relatively large internal diameter so that the liquid may be freely poured into the vessel without accidentally spilling from the sides thereof. After the. inner vessel is filled, the insulated closer section 41 is placed on the mating breast section 39 and securely fitted thereto so as to minimize the possibility of the air entering the joints between both sections. The section 4 of the outer vessel is then connected with the section 3 and locked thereto by the sealing Wires previously described. Then desired, the breast section 3 of the outer section may be removed from the section 2. so as to expose the breast section 39 of the insulated lining and permit said section and the bottom section 34 to be entirely removed and treated to a sterilizing bath.

incident to the fact that the breast 21 is curved as described and that the breast 28 is arranged with its walls parallel with the walls of the breast 29. the section 39 of the lining will be held against movement in an outward direction when the structure is eanted to pour the contents from the inner vessel. At dialnetrically opposite sides the breast section 3 oi the outer vessel is provided with suitable hand gripsorhandles 51.

mesme inner and outer vessels; a closure for the inner vessel, a closure for the outer vessel, and a closure of insulated material fitting one of the lining sectionsand interposedbetween the closure of the outer vessel and the Closure of the inner vessel.

2. A shipping can comprising an outerr` one end of the outer vessel, a sectional lining of insulating material interposed between the inner and outer vessels and terminating below the outer end of the neck of the innervvessel, a Closure fitting the'neck of the inner vessel, a closure for the outer vessel and a closure interposed between the closureof the inner vessel and the closure ot the outer vessel and removably tting the adjacent end of the lining.

4. A shipping can comprising an outer vessel, an inner vessel, a sectional lining of insulated material interposed between the inner andouter vessels, a closure for the inner vessel, a closure for the outer vessel, and a langed closure of insulated material having a beveled lower edge fitting one of the lining sections .and interposed between the closure of the outer vessel and the closure of the inner vessel, the beveled flange of the last named closure engaging the outer surface of said lining.

5. A shipping can comprising an outer` vessel curved inwardly to provide a vertical flange, a lining of insulated material interposed between the inner and outer vessels, a closure for the inner vessel, a closure .for the outer vessel provided with a flange adapted to embrace the flange of the outer vessel and having a beveled lower edge adapted to contact with the inwardlycurved portion of said outer vessel, a flanged closure for the lining provided exteriorly with a reduced portion for the reception of the flange of the outer vessel, thereby establishing an -air tight joint between the inner and outer vessel.

In testimony whereof I affix my signature in presence of two witnesses.
