VENTILATING CAN LID.-

Appncation lea March 2, 1926. Serial No. 91,756.

.self-adjusting and is therefore adapted to fit tightly, of itself, when inserted in acan mouth.

To the attainment of the foregoing, the invention consists in the improvement as hereinafter described and definitely claimed. In the accompanying drawings, forming part of this specification Figure l is a fragmentary elevation of a can with the lid constituting thev best practical embodiment of our invention of which we are aware positioned in the mouth of the can. c n u Figure 2 is an enlarged perspective of our novel lid per se.

Similar numeralsof reference designate corresponding parts in both views of the dra wings. f f

The can l illustrated' is provided with a. mouth 2 and is otherwise of the ordinary well known construction.

Our novel lid is providedwith a top 3,

and a handle It, vand is also provided with a flared upper annular portion 5 which is designed-when the pendent portion of the lid is inserted inthe mouth 2, to prevent dirt from dropping into the said mouth. The chief feature of our invention resides in an annular skirt 6 of sheet metal appropriately connected with'and pendent from the top 8. The said skirt 6 has upper end portions lapped as designated by 7 and connected together by rivets 8, and the skirt also has lapped, lower endportions 9 which are not connected together, and consequently the lower portion of the skirt is self-adJusting, and is adapted to be tightly crowded into the mouth 2 so that ythe frictional contact be- For Ventilating purposes the annular skirtV 6 is provided with spaced upright slots 10, the ends of the said slots lO being preferably rounded as illustrated to facilitatethorough i'cleaning thereof. The slots 10 extendl in series entirely around the skirt 6, and in the preferred embodimentof our invention we also employ in the skirt upper apertures ll, the said apertures ll being, by preference, r arranged in vertical alinement with the slots 10, and one aperture ll to each slot 10.v

`It will be readily understood from the. foregoing that when our novellid ispressed down `in the mouth 2 to the ful-l extent, the flared flange or marginal portion 5 by cooperation with -thevupper edge of the mouth 2 will effectively Vclose the can and exclude atmospheric air therefrom. XVhen, however, the lid is positioned fin the mouth 2 so that portions of the slots 1 0 and the apertures l1 are exposed to the atmosphere, it

will be manifest that the lid will adequatelyl ventilate the can, the amount of ventilation depending upon the extent to which the skirt portion of the lid ismoved downwardly into the mouth 2. Inl this'connection it will be noted'that when but very little ventilation is desired, the skirtportion 6 of the lid is moved downwardly into the mouth 2 to such an extent that the apertures il alone are exposed above the upper edgeof the mouth 2.

The skirt of Vour novel lid' being formed of appropriate'sheetmetal, it follows that .notwithstanding.the foraminous character of tion in order to impart a full, clear and exact understanding of thesaid embodiment. .XVe

confining ourselves to they precise construction disclosed, our invention being defined by our appended. claimswithin the scope of which structural changes and changes in vrelative arrangement may be made without departure from our invention- Having described our invention, what we Yclaim and desire to` Secure by LettersPatent, is

10o do not desire, however, to be und'erstood'as l. A Ventilating earn lid coinprisl g zi top, an upwardly extending outwardlyv flared marginal flangethereon7 a handle on the top, and an annular skirt portion of sheet metal carried by and pendent from the top and. having' upper lapped end l'ortions'eonneeted together and also having lowerglapped end portions tree 'to move with respecttofeach other, and `further h ving in .its lower portions forainina for Ventilating purposes.
