' 4 Claims. 1.

The present invention relates to' a metalhermetically sealed or air-tight tearing strip'container or can having one or more'interior collars arranged inside'of the can and hasparticular reference to a multiple part body having sections spaced apartbut secured tothe collar orrcollars in one or more'circumerential jointswhichcan be soldered from the exterior ofthe container and the container after opening can be hermetically resealed by a replaceable air-tight reclosure'cover. The usual tearing strip' collar container after opening can be recovered as contradistinguishedf from resealed by the detached can endor cover. This being so it is not necessary that the collar be joined to the can body in a sealed joint and" Soldering of the collar to the can bodyy would' appear to make fora simple and efficient air'-v tight reclosure at such junctionk but soldering necessarily must be carried outon the inside"v of` the can body and this presents many manufac turing diiiiculties. n

The present invention contemplates the forming of the body member by joining two'or more separate complete tubular can body sections through the intermediacy of one or more interiorAk beaded collars in such a manner as to cause the bead of the collarto function as a spacer element for the adjacent body elements, this'construction exposing the adjoining edges Aof the body sections4 as well as the collar bead on the outside so'that an eiTcient soldered joint may be easily made at this connection by'exterior soldering.

An object of the invention is the provision ofa multiple part container body joineditogether by i one or more connecting interior collars and'providing a container inwhich the body sections'are spaced apart by the collars With'the lines'of'juncr ture exposed to the outside or container exterior from which it is soldered.

Another object ofthe invention is theprovision of a reclosure tearingfstrip containerconstructed of two independent body sections anda connecting interior collar all joined in an' exter-l iorly soldered joint in which after opening of the container by removal of thetearing strip, theopened container is reclosed in anair-tight jointV by sealing the collar. l

Still another objectisthe provision'ofa tear'-` ing strip collar container ofthe character de`'v scribed in which thecollar carries a reclosure :z which is exposed to accessfor` resealing' purposes by initial opening of the can.

Numerousother objects and advantages ofthe invention'willbe apparent asA it is better understood from the vfollowing description, which, taken in connection with=the accompanying drawings,`

discloses a preferred embodiment thereof.

Referring to the drawingsz- Figure A1 isa perspective viewbf a multiple' body soldered container embodying the present invention;

Fig. 2 is' anenlarg'ed sectionalview taken sub'- stantia'lly along section line'- 2"-2-in Fig. 1; and

Thepre'sentinvention embodies a container formed"r offa'pluralityor vmultiple number of independent*can bodies.v drawings, these body parts may consist of Va body section llfand'a'bodysection 12;- The body sections are each frictionallytt'ed'on a connecting interiorv collar I3. This collar is beaded as at I4`r isexposed'onlthe exteriorof the container.v This construction makes for easy soldering of the parts' as at i5 by applicationv of the solder to the outside Wall and Vthus-lends itselfto arapid commercial I'soldering operation. Obviously ifa longer can isjdesir'edimore than two can body sections can' paused with'fthe'- necessary number of icon'- necting collars:v

screwing the'reclosure cover 35.

From the beaded portion I4, the collar I3 ex'- tends along the interior of the body section II, this being onejof the tightly iitting parts of the collar. At the lower score line 2| the collar wall extends inwardly and upwardly in a double rounded corner 25 which merges into a cylindrical vertical wall 26 spaced inwardly from the body wall.

In other words this wall 26 is of a smaller diam--` eter. At the top the interior wall 26 terminates in an inwardly extending reclosure curl 2'I which provides a smooth mouth and reclosure seat for the upper score line extends into the upper double seam locality I9, this portion of the body wall being designated by the numeral 3|.

A reclosure cover 35 is contained Within the can and is of such construction as to be lightly carried on the interior collar I3 when the can is sealed initially but is made usable as a reclo-V Y merges into a conical wal1r43. At the inside and at the top the conical wall 43 extends by a gently curved corner '44 into a central panel 45. Preferably the plane of the central panel 45 passes through the top of the arched section 38 so that the cover 35 constitutes in effect a flush cover. Cooperating Vthreads 48, 45 are formed respec- The body wall II above v sections thereof spaced apart, an interior spacer tively in the collar wall 26 and in the cover skirt A sealing Ygasket 5Iis disposed in the annular groove formed on the under side of the arch wall 38. At the time'the can is readyV to be initially sections by means of an interposed interior collar insures that the collar can be easily and efficiently soldered within the body.

It is `thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope 0f the invention or sacricing al1 of its material advantages, the form hereinbefore described being Y merely a preferred embodiment thereof.

The gasket 5I isconcerned with the re-Y closing. of the opened container and this light engagement is only a carrying position. When the top cover is seamed onto the can and it is fully sealed (as in Fig. 2) there is no danger of the enclosed reclosure cover 35 becoming unscrewed eventhough it is only loosely applied, as the outer cover Il prevents such displacement. f

Upon removal of the tearing strip 23, the top end closurell together with the detached body wall part SI may be thrown away as no longer of service.
