(cl. y4-?.'1`1)` resilient strapyL'adaptedftointerlock with and This invention relates to receptacles ofthe `type made from sheet material, such, for example, as sputum cups and the like containers which are' intended to be destroyed after use.
In articles of this character it is essential that i' the receptacle be provided witha suitable cover which is normally closed and which may be con"- veniently opened, and it is` the principal object of the present invention to provide va receptacle of tlns Jtype having a normally closedcover inember which is hinged `to the receptacl'egwithout the use of fastening means-other'thantliose constituting an integral part of the cover and receptacle, and which is constructed so that the cover may be quickly and conveniently opened byr a finger of thel hand supportingl or holding the receptacle.
Another object is to provide a covered receptacle formed of two parts, one part being adapted to form the cup and the other part the cover, both parts being formed with'complem'entary interlocking means so designed that ther receptacle may be quickly erected and assembled with the cover so that the parts are not 'subject to accidental separation.
Further objects will be apparent from a vconsideration of the following' description and the accompanying drawings wherein:

In the embodimentshown in Figs. 1 to 3, the
cup is formed from a blank B scored to provide llines of fold (indicated by the dot-and-dash lines of Fig. 1) vand define a bottoni l, kside walls 2,` 3, lA and 5 which are interconnected by'foldable portions 6, 1, 8l and 9. "Theouteriedges ofthe sides 2, 4 and 5 are formed with projections I IJ,

In order to `prevent accidental separation `of. the cup kandcove.'I the `lower section `I8 oftongue 2B may be provided with transverseslits 2liI (Fig...1)deningflocking -tabs 25 (Fig. 4) which are bentdownwardly so as .to engage the strap L and thusprovide `an interlock `which prevents the cover C from being removed fromthe'cup.;4 c Y. f n c Q.
The embodiments shown in Figsf 5to 12 kare generally similar toY that 'shovvn-` in .F.igSL 1 vto 44 and the same or similarreference charactersare appliedto corresponding parts. ln Athe embodiments inFigs. 5 and.6,.the naps; lll?i on side Walls 2 and lIl ,interlock 'with the .fcldaple ,portions s-a,
as showninF'ig. 6, Ato hold the cup in erected position, no provision.beingmade` for a retaining l allge., Sidelwall is formedwith' a tongue 2l).a
The embodiment *shown in Figs'l andk 8 is substantially the same as that of Figs. 5 and 6 except that its tapered tongue 2l]a is provided with transverse slits 2da dening rectangular- -r shaped locking tabs which are bent atvright angles to the face of the tongue to provideanV interlock for preventing the cover from being' separated from the cup.
The embodiment shown in Figs. 9 to l142 :is substantially the same as that of Figs. 1 to 4, ex-
cept that the extension I5a is provided with *a oi" the cover with its edgespinched `between the .fr
cover and the depressed-strap. Inseachembodiment the tongue .0n-,the ,receptaclewhich passes throughthe slits inthe-cover mayfhavefparallel sides but -isspreferably tapered` to` facilitate insertion andto `wedgetightlyagainstthe ends of the slits. While the locking tabs` may be omitted in each embodiment, theyserveto hold the cover Yin .place `more positively. I-tiwill also be noted that Vthe marginal portion-of :the cover overlying the supporting tongue provides a lever-'like handle by means -of which the cover'may be `conveniently swung `open when the cup is held in the hand. By depressing the -strapasaforesaid it is arched downwardly. '.Ihus when itis pressed against the back of thejcu-p .openingthe cover, the arched portion isicompressed andits resili-+ ency tends-to start the 'coveritoward closed'position when the coveris released; VBy locating the strap L in juxtaposition to the back' of the b'o'x, it flexes the back inwardly when fthe cover 'is opened, and this also 'yielding-ly ,urges 'the cover toward closed position when 'the cover is released.
From the foregoing it will be evident that in one aspect an important feature of the invention consists in that'A shoulders are provided on `the aforesaid tongue to engage theledge of one of the slits in the cover, thereby to restrain the tongue from pulling out of the` slits. VThus in the illustrationsthe/e'dges 24 and ,2da ofthe tabs 25 constitute shoulders whichenga'ge the edge of the rearslit in the cover. j
While I have shown and described diierent desirable embodiments of the invention', it ist@ 'be understood 'that 'this ,disclosure .is for the purpose of illustration and that various changes in shape, proportion and arrangement of parts, as well as the substitution of equivalent elements for those herein shown and described, may be mafd'ewithout departing from the spirit and scope of the invention as set forth in the appended claims.
