As illustrated; my improved bag has front and back sidewalls II)` and II, and has end walls I2 `.3:5 and I3 which have center creases I4 for allowing the bag to be folded into flat condition. I'hese walls may-be formed of a' single sheet of paper in l the manner well known in the art. The material from which the walls are formed is preferably a strong paper whichhas been impregnated with x coating preferably contains a small amount of s I siichas benzine,` 'for I have found that the benzine orother solvent aids in enabling' the latex v to form an intimate union with the treated paper.

As shown by Fig?, the latex coatings 30 extend upward of the bottom edges and along the exterior 5# i of sides `IIl and VI`I to cover they lower portion of the sides.` "i The bottom edges are first dcubledback i and pressedtogether against a sidewall toform, anedgesfold I5.'

The multiple fold M `I 5a thus formed is tightly pressed out at its edges,

and preventsthe contents ofthe bag from making the turns in the multiple fold. When the bottom folds are made in the manner just described, the

In the embodiment illustrateda triangular shaped piece 30 is clipped. offsoas to provide" flaps havingtaperfi ving edges. f With the cornersremoved inthis way it' willbe seenthatthe tapered edges I6 a`ndl1, of side flaps I8 Iand4 I9, are evenland llniferm` withy theltapefed 'enges :nella 2| of endfiapszz and 3 5 23..` instead ofv clipping` the corners of the "bag, the end vfolds 24jan`d 25 may simply be slit or torn n down from the top' to form the sideand end aps,

if desired,4 n Itis essential onlythat the ends be severedfrom the sidesat the top, so that thetops of the ends may `be 4turned clown as naps when it l becomes necessary. v p p f fj p The sideflaps I8 and I9 are givena coat of latex on" their inside` surfaces. `A convenient way of doing this is to staokthe bags with the top ends 45 offset so as to expose a portion `of the end of each bag. Then with flaps IB turned down the coat-` ings 26 of latex are administeredtomany bags at one time. Inra similar way coatings 21 of `latex are given to flaps I9 of the bags.` The latex mate-` 50 rial here used should `preferably contain aismall amount of benzine as before explained in connection with the bottom seal. No special precautions needbe takenefor the protection of coatings 26 and 21, for until the bags are to be usedthe end and automatically protect them during packaging and shipment. Due to the peculiar qualities of the latex, it will not adhere to the paper of the end flaps, and consequently there is no danger of the flaps being stuck fast before the bag is used.

` In the 'use of the improved bag, the sides I0 and l I are spread apart, causing the end folds 24 and 25 to be expanded/ When the bagl is completely opened andthe ends 'and sides are at right-angles, the end ` ilaps 22 and 23 are turned downward in a manner illustrated in Fig. 4. vBy creasing the end aps slightly at their base they are caused to remain approximately at right# angles to the body of the ends. If the bag is to be used in a toilet receptacle of rectangular form,

both the side and end flaps may be turned downr as just explained,.and the bag'inserted into the container'so that the side'and end ilaps extend over the top of the receptacle. The flaps then serve as a means of securing the bag in place. For example, a toilet 'seatinay rest upon flaps 22 and 2l and open directly into the bag.

The end flaps 22 land 2:3 whenthus turned down, perform an' important function' in strengthening the ends against falling inward. In ordinaryv types of foldingffbags there is a great tendency for the ends to Atall inward, and this tendency hfas been very troublesome. Where it is essential that the top opening of the bag be fulleand f ree, this tendencyfpresents a serious disadvantage. The end a s 22 and 23 when turned down in the positions own in Fig. 4, make the top edge rigid and al1`tendency of the ends to refoldis overcome. The effect of the flap in preventing' the inward bending Yof the ends is comparable tothe eifect of an angle iron when used to reinforce a member against bending.

If preferred, the flaps may be bent over farther so VthatV the tops of the flaps are directed down'- ward. 'With the flaps turned'backward in this manner the top edge porti has a U-shaped cross-section. In some situa ons it is preferable that theiiaps be turned 'down in this fashion rather than as shownfin-Fig. 4. For instance, theap maybe turned do'wn inside the top edge of a metal container, and :in such'case'the ends are held rigid and prevented from falling inward bythe U-shaped fold. A

,When the bag hasbeen used and is to be disposed of with its contents, the side flaps" I and Il may be easily brought together by pressing only slightlydownwardly and Vinwardly against flaps 22 and 23 at their centers where the creases 1I are. This pressure will'cause the ends Vto fold inwardly with their' fla'ps folded downwardly as indicated in Fig. 5, so that as sidhefiaps I8 and i9 are .brought together, the` endiiapifv will not now keep coatings 26 and 21 apart. `By rmly pressing side flaps I8 and I9 together'with the fingers so as to bring their coatings completely into contact, a very tight and secure sealis formed.

Thus sealed, the bag with its contents may easily be carried to a place of disposal. The bag may be ruptured to allow the contents to spill out and then may be burned.

'I'he bag constructed as just described is not affected by the disinfectants and deodorants which are commonly used in toilets and garbage pails, and the latex coatings employed in this improved bag provide an important safeguard against the spilling of Vsuch disinfectants and waste matter about the premises.

While I have described a specific structure as illustrative of my invention,5it will be understood that many changes in'the construction may be made without. departing from the spirit of my invention. 'I'he foregoing detailed description has been given for clearness of understanding only, and no unnecessary limitations should be understood therefrom, but the appended `claims should be construed as broadly as permissible, in view ofthe prior art.
