- An insulating shipping container of thef Y generai typeemployed for the storage d and transperttien of perishable teeny-aad to W in:einen-teieeftanticultny@e las plicable, although not limited solely to use with such types of containers, is disclosed more or less diagrammatically in the accompanying drawings purely by way of example for the purpose of explaining and describing the principles and features of the invention. The shipping container 10 illustrated herewith, is characterized by and includes the container body, in the present instance of cylindrical form, but not limited to any particular form or shape, comprising the side wall of insulating material 11, having the mouth member or ring 12 at and forming the open upper end or mouth of the container, and the outer side covering la, together with the bottom 15 formed of insulating material with the outer covering 16, all providing the insulating container having the interior space or well for receiving the materials to be stored or transported in the container. Any suitable or desired insulating closure or cover (not shown) is of course provided for tightly closing and sealing the open or mouth end of the container, by' fitting and sealing onto the annular internal, depressed shoulder or seat 12 formed around the mouth member or ring 12, as -will be readily understood by those skilled in this art.

Vithin the container 10 so formed, a liquid tight lining, such as the metal can or receptacle 20, is snugly and tightly fitted with the open end 21 thereof disposed or terminating a distance below the cover receiving seat or shoulder 12 of mouth ring 12, and alined with and accessible through the open end or mouth of the container, defined by the mouth member 12. The lower end or bottom of the lining or can rests and is supported upon and insulated against temperature exchange by the insulating bottom 157 as will be clear by reference to the accompanying drawings. 1With such liquid tight lining or can 20, considerable diiiiculty has been encountered in securing and mounting thesame within the'container 1 0 against movement and displacement under all conditions of use and handling, and in preventing leakage between the upper end 21 of the can or lining 2O and the adjacent container wall, which in the present inst-ance embodies the mouth member 12 andthe insulating material 1l. p Y

In the example hereof, the mouth ring or member 12 is formed of a suitable material, such as wood, although not restricted to this particular material, having insulating characteristics, and the metal can or other'suitable material lining 20, extends a distance over the inner side of this mouth member, to

- terminate at its open upper end 21 below the cover seat or shoulder 12 of the mouth member. In accordance with the invention, the inner, lowed side or face of themouth ring 12 is cut awa inwardly and upwardly a distance throng the lower end or edge thereof to form the recess or groove 22 therearound having the downwardly facing shoulder 23 at the upper (outer) end thereof (see Fig. 2).

Adjacent the upper end 21 of the can or receptacle 20, the can wall is formed in any suitable manner with a circumferential, exterior bead or rib 24C projecting outwardly therefrom in line with the upper end of mouth ring recess 22 and received in this recess beneath and maintained against outward displacement or movement by the shoulder 23, with the rib 24 preferably relatively tightly bearing against and engaging this shoulder23. Preferably, the upper inner edge 11 of the insulating material 11 of the container wall at the lower end of recess 22 is inclined or rounded inwardly and downwardly from the lower end of recess 22, to can 2O to form in effect a continuation of the recess of decreasing width, as will be clear by reference to Figs. 1 and 2 of the accompanying drawings.

The space formed between the wall of can 20 and the insulating wall 11 and mouth ring 12, by the recess 22, is filled by any suitable sealing material, such as asphalt, to form a seal 25 between the mouth member or ring 12 and the upper end 21 of the container lining or can 20, to prevent leakage or passage of air and/or liquid'therebetween. The location and formation of the seal 25 around the under side of the rib 0r bead 24: of can 20, with the upper side of this bead bearing against mouth ring shoulder 23, while the lower end of the can is supported by the container bottom 15, permits of forces tending to outward movement or displacement of the can being taken up directly vby the shoulder 23 of the mouth ring 20 from rib or bead 24 without affecting seal 25. The forces tending to downward or inward displacement of can 20 are transmitted thereby directly to the container bottom structure 15, also without affecting or submitting seal 25 to any loads or forces. In this manner theA lining or can 20 is secured in position within the container 10, between the container bottom 15 and mouth member shoulder 23, while the seal 25 between the upper end of the can and the container walls is protected against all undesired forces.

The bottom or inner end of the liquid tight lining or can 20, is formed and constructed with a bottom wall having the outwardly turned flange 31 received and suitably locked and sealed within the inwardly and upwardly turned flange 32 of the can side wall, thus forming the depending annular flange joint 33 around the bottom of the can with the bottom wall 30 inset with respect thereto (see Fig. 3). The bottom 15 of the container is formed-of a suitable depth of insulating material and at the inner side thereof is formed with an inwardly or upwardly extended central portion or centering disc 34 which provides an annular groove 35 therearound into which the flange joint 33 of the can 2Ov lits and is suitably sealed if desired, with' the disc portion 34 of the container bottom titting snugly up into the space within flange joint 33 and against the can bottom wall 30.

(Thus, the cam bottom lits downonto, over the 'portion 3470i? bott-om 15 and is maintained y open upper end thereof vand the container wallV by the seal 25. The bottom or inner closed end of the can 20 can likewise be sealed with the adjacent wall and bottom of the container if Vfound expedient, the bottoml v groove 35 providing space for forming such seal, as will be clear by reference to the drawings, and particularly Fig. 3 thereof.

Preferably, asshown by Figs. l and 2 of the drawings, the open upper end 2l of the y lining or can 20, above the lrib or .bead 24,

is inset into the adjacent face 'or' side wall of mouth member 12, as by slightly cutting away the member, so that the finner surface of the upper'end 2l of the can is substantially flush with the inner wall of the mouth member. This eliminates any projection of the upper end edge of can'20, as will be readily understood, although the invention is not so limited. Y v

The-construction of the inner can V20 and cooperating structure of container 10 is simple and permits of `ready assembly. For eX- ample, in assembling a container, the upper end of the can 20 can be inserted from the lower side ofthe ring, the ribAor bead 24 passing freely into position through recess 22, the seal 25 canthen be formed, after which the insulating wall positioned Yaround can 20, -and then the bottom structure 15 applied. The invention thus provides a structure which lends itself to low cost manufacture, and yet which provides a practical and eflicient lining or inner can mounting and securing intoand as an element ofa con.-V

tainer, with the can eiiiciently sealed'to prevent leakage between it `and adjacent container walls. Y

It is also evident that various changes,

i modifications, substitutions and variations j sa might be resorted to without departing from the spirit and scope of my invention, and hence I do not desire to limit myself in all particulars to the enact and specific disclosures hereof. v
