A Mus ums- 1 SPECIFICATION i; This av-mall relates generally i trash bags.

i A principal object of the. present invention'is to provide an improved trash. bag which isldesignjed particularly; for the disposal of refuse containing germs, orwhich has anodor', and which is accordingly readily adaptab le. so to maintain sanitary conditions;

Another objectof the present invention is to provide an inflatable bag which is particularly adaptablefor in the home. automobile," professional offices wellas hospitals and the'likeiQ t Yet another object of the present invention is to provide an inflatable bag which is readily adaptable for receiving clonlaminated and soiled'paper. tissues, surgical dressings, swabs Yet another object of the present invention is toprovide an inflatable bag which maybe inept in an uninflate'd and eom jand -whichlisj readily inflatable soas to. stand up in a rigid whereinzigl I I g y a FIG; I is a perspective view of the present invention;

FIG. 2 is a cross-sectional view taken on the line 2-2 of FIG.

hand FIG. 3 isa cross-sectional view taken on'the line 3-3 of FIG. Referriiig'now to thedrawing in'detaiLythe reference numeral represents an inflatable bag according to the present invention wherein there is a bag body 11 which is comprised of an outer, expandable shell '12 and anonexpandableinner liner 13 in spaced apart relation soas to provide an air space 1 l4 therebetween. This double wall'construction is provided A top wall 17 made of expandable material comprises only a single thickness and does not include the inner liner, as shown in FIG. 2 of the drawing. The top wall "includes a central slot 18 through which refuse may be deposited into the central compartment 19 within the bag body. I

A tab 20 is secured to a rear edge and rear side of the side of the "following "specification and the accompanyingfdrawing around the side wall .15 of the body aswell as the bottom wall The inflatable bag may be variously modified in tion such as the use of rubber sheeting for the expandable shell and plastic sheeting for the inner liner so as to be nonexpandathinflated air space will hold the air forced therein through the air valve 22..

in" operative use, when it is desired to dispose an item of [refuse,-,the lips of the slot 18 will readily part so as to provide sufficient spacefor introducing therefuseitem; after which the slot ls'willagain close-up thus preventing germs or foul a suggested materialfor the inflatable bag would comprise polyethylene plastic or the equivalengand the .valve 22 may be of inexpensive'rigid plastic. it may berattractively colored so as to hide the refuse containedtherein.

CODSUUC- ble and yet wherein both elements are of airtight material;

it is tobe noted that a plurality of webs-23 may be provided between the outer shell and inner liner, as shown in FIGS. 2 and 3, so to maintain a generally equal space 14 all around .betweenthe shell and liner; the webs being provided at the corners 24 of the inflatable bag.

While various changes may be made in the detailed construction, it is understood that such changes will be within the spirit and scopeof the present invention as is defined by the appended claims. 1 lclaimz y 1, in an inflatable bag, the combination of a bag body said bag body being made collapsed for purpose of compact 1 storage, said bag body having self contained means for being expanded so to stand up in operative use, said means comprising an outer shell and an inner liner, said shell being made of an expandable material, said liner being made of a nonexpandable material, said shell and said liner being in spaced apart relation so to form an air space therebetween so as to maintain said bag body in an erect upstanding position, said bag body including a side wall fully around, a bottom wall, and a top wall, said sidewall and said bottom wall including said outer shell and said inner liner, while said top wall comprises only said expandable outer shell, said top wall including a cen- 7 wall 15, the tab 20 having a slot 21. thereinso as to be readily fitted over a hook or supporting nail orthe like.

. A one way air valve 22 is secured to the expandable shell of the side wall'for the purpose of inflating the air space 14.

between the shell and liner. l t will'thus be readily apparent that the shell and linerare made of an airtight material so that tral slot for purpose of receiving refuse therethrough, and said side wall including a one way air valvesecured to said shell so as to allow entry of air into said air space between said shell and liner. i

2. The combination as set forth in claim 1 wherein a tab is secured to a rear side of said body, said tab extending up wardly-of an upper edge thereof, said tab having an opening therethrough so to be received upon a supporting hook or the like. 3. The combination as set forth in claim 2 wherein a plurality of webs are secured between said shell and liner so to maintain said air space equidistance all around therebetween said webs being located at the corner of said bag body.
