vBe it known ,that I, WILLrAiu F.l SCHUMAN, a citizen ofthe United. tetes, residing at f Buchanan and ful improvements in Milk and Cream Cans, of which the following is aspecifioation..

The invention relates to Lan improvementscreening the air inlets against the admis-l sion of insects or the like.

2t 1 A `following specification, reference being had- The invention WinI be described in ne particularly to the accompanying drawings, in Which-J Figure 1 is a broken vertical section of a can .and cover therefor, the .latter being shown provided With the improvement Fig. 2 is an enlarged broken vertical section, partly in elevation, of one of the air inlet tubes and cap therefor.

Referring particularly to the drawings,

' my improvement is designed primarily to be incorporated in the cover 1 of an ordinary milk can 2, it being understood 4that the cover and can are, aside from the particulars hereinafter noted, of the usual construction, including a flange 3 tofit snugly Within the mouth flange Il of the can, from Which flange 3 the cover is extended in the form of a aring upper portion 5, the cover at the juncture of 'the flanges 3 and 5 being formed with' a transverse plateG forming the sealing member for the contents of the can when the cover is in place. The plate G is provided with an operating handle 7 by which the cover may be conveniently. removedv and applied, said handle being preferably included wholly Within the planev of the flaring flange 5, and being of less length than the diameter of the plate 6.' f

The plate 6 beyond and preferably in alinement with the handle 7y isformed with openings 8, which openings are preferably Varranged immediately' adjacent the peripheral edges of the plate and in diametrically opposed relation, as shown. Fitted Within the openings 8 and secured to the plate t3 are readily secured in place,`

air Vtubes 9', the lower ends'fof whichterminaterin alinement "with the Ilovv'er edge of the fiang'e -3 of .the cover, While the upper edges 1project a slight distance above the' plate 6, terminating, however, below the' free upper edge of the fiange.' By forming the openings 8 immediately adjacent thev peripheral edges of the plate 6, the Walls of the tubes 9 are adapted in part to -bear throughout that portion of their lengths below the plate 6 against the flange. 3, thereby bracing the tubes against displacement by accident and permitping their being more The tubes 9', which are -open bottom, are each provided -with What I term straining caps 10, comprising disk heads 11` at' top and of adiameter .exceeding that ofthe air tube and depending sleeve-like sections 12 having an exterior diameter corresponding to lthe interior dia-meter of the tubes 9. The sec-- tions 12 are thus adapted for sliding and frictional engagement with the interior survface ofthe air tubes and are perforated at 13 throughout the entire surface,'as clearly shown in Fig. 2. The disk 11 are provided with operating handles 14, preferably in theA form of rings secured to the disks in an appropriate manner.

in use'it isobvious that by adjusting i eitheror both of the straining capseso as to dispose the disks 11- thereof above the upper edge ofthe air tubes that'itf-free circulation of air is permitted through the walls of the caps and through the ai? tubes to the milk or cream in the can, thereby'preventing to a material extent the deteriora.- tion or souring of the contents of the can. it is equally obvious that the air supply to the interior of the can may be regulated by the adjustment ofthe air caps, and also-that With thecaps in place the entrance of insects or foreign niatterto the interior ofV the ca-n is practically prevented WithoutV in terfering with the circulation ofthe air.'

The can and cover described and iilus-I trated are intended to represent any usual or preferred construction of these parts, it

being understood that the improvement is readily applicable to any cover in use. Having thusdescribed the invention what is claimed as new, is v 1. A can cover including a sealing plate, an edge iiange'depending from the plate in one directionand.projecting from the plate in tlm mmnste direction, air tubes secured `one dn'ee'ion and pl'ojeeting from the plate et dmnerenlly opposed rela/tion in the 5 terminating at their lower ends in :dluenaenv 'I5 plete, Suid tubes belng open at both Yends J with the flange extending beow the pnle :1nd ern'lnmtlnn :zt thenflower ends 1n nhnei :md at then uppel` ends below the upper ment w'ih the Hnge extending' below the plate :1nd at their upper ends below the upper edge ogf' the angje projeeting' above the plate, and Caps carried by the upper ends o1 Suid tubes.
