recense son application ined staren 2 My process relates broadly to the art of sealing cans and particularly to a process for hermetically sealing cans which contain products which deteriorate with exposure to air.
It is the object of my invention to add to the knovvn steps of can labeling a final treatment Whlch'xvill result in rendering the label moisture 'and air-prooi' and which will also seal tightly a printed paper label, which may be pasted over the joint between the can body and lid. It is further my'objeet to coat a printed label with a thin layerol'. varnish su sequent to the application so that the ect of a lithographed can is. Well simulate I have illustrated a preferred application o m process in vconnection with the requirec steps of hermetically sealinga baking powder `package of usual type. The type of can which I have shown has a slip-on cover or lid which telescopes over the open top of the can body.
Referring to the drawings:
Figure 1 is aside elevation of a. can body.
' Figure 2 is a side elevation of a cover for the can.
Figure 3 is a side elevation of the canu'itli the cover attached.,
Figure 4 is a plan View of a label.
Figure 5 is a side elevation after the application of the label to the can Figure 6 is a side elevation of the labeled can after the lnal varnishing step.
The can body, which is generally indicated `at l, has an annular top edge portion 2, which is adapted to 'l'rictio-nally seat a. lid or cover 3. The slip-on cover, as this type of closure may be called, telescopes down over the annular top edge of the can body. A label 4 of sullicient Width to extend approximately from the bottom edge of the can to the top edge of the lid is pasted around the can so as to overlap the joint between the lid and the can body. If a' varnished printed Wrapper is applied to the can, there are usually Wrinkles in the Wrapper which extend lon itudinally from the can joint to the edge of t e Wrapper. Such wrinkles prevent a hermetic seal and then, if unvarnished wrappers are used, the paper itself being clasica QN', OHIC, ASSGNOR T0 THE KENTN BAKING POWDER nro, A consumimos: or omo.

somewhat porous will allow some passa e of air through to the joint of the lid an can.
The diculty with wrinkled wrappers is particularl noticeable when large sized cans are packet. In order to make the Wrapper vfit snugly about the can I have found that if the Wrappers are inoistened prior to their application and then are heated subsequently to their application, the wrappers Will .shrink and tit snugly about the cans. In the case of Wrapping cans that do not have a slip-on cover or which are of small dimensions the use of Wet wrappers and the shrinking ot the Wrappers about the cans is net essential. Notwithstandin a thorough drying of the cansl after t e Acans are wrapped improves the snugness of the fit of the Wrappers.
As a. final `treatnfient to insure a substantiallyy hermetically sealed joint'between the can Vand cover and give the appearance of a hthographed metal body, I coat the side Walls of the .can with varnish. I have indicated a coating of'varnish as applied to the the can at 5, in Figure 6. I preferably utilize my novel process for coating the cans as disclosed in my (3o-pending application, Serial No. 127,602, filed August 6, 1926, which ,application will issue as Patent Number j, 1,622,174, of March 22, 1927. In this process the can is placed between tworollers, to which films of varnish is supplied, one roller which rotates the can, and another roller which rotates at an increased speedand thus builds` up a Wave inthe varnish film which thoroughly coatthe side Walls of the labeled cans. Other device for applying the varnish to the walls of the can may be used, however, and I do not Wish to limit myself to the particular method described in my copending case. It will be apparent that any ridges in the position in which the wrap er overlaps the joint will tend to be smoot ed over with the application of the varnish so that a can having a smoother 'and neater appeamnce will result.
Having thus described'my invention what I claim as new and desire to secure by'Let ters Patent is:
l. The process of labeling cans which n www4:
Consists in moistening the wrappers, applydnmpned Wrapper to tht! side walls of the ing a wrapper to auch can, drying the can s0 as to overlap the, joint between the wra ped can, and mrnishing the side 'walls cover and can, cil-ying the wrapped can, and 10 of t e' cnn subsequent to the application of applying a coating of vannslh tothe dried 5 the wrapper unc drying thereof. and Wrapped can.
