Abstract
A receptacle (10) is constructed having first and second broad sides connected along side and bottom edges (12) and (14), respective-ly. These sides are in turn constructed of an outer layer (28) of flexi-ble, durable fabric material, and in one embodiment, an inner layer (26) of the fabric material. In this embodiment, a barrier material (24) may be placed between the inner and outer layers of at least one of the sides. In a preferred embodiment, a flap closure (20) configured as a cuff (40) extends from one of the sides adjacent opening (18), and folds over opening (18) so as to close the opening.

DETAIL~D ~SCRIPTION OF T~E DRAWINGS
l~ Whlle a durable, reu~ahle recetacle 10 as shown in Fig. 1 i~ particularly desoribed in the pre~erred embodiments of this disclosure, it is t~ be appreciated that construction and materials of th~: receptacle may vary without departing : from the scope of ~his invention. A~ shown, recept~cle lO is obasically:a flat~ened pouch or bag stFucture closed on first, e~ond, ~nd third edges 12, 14, and end 16, respectively, with the ~ourth edge l~ being open. As such, article~
requiring:protection of one type or another may be placed in rec0ptacle IO, as~ illu~trated by a dental pick 22 ~dashed lines). Tn ~ddttion to medical instruments, a receptacle lO
: may be e~sily ad~pted for other purpo~es; for instance by constructin~ a proteotive carrier for electroni~ circuit boards by coating a receptaole lO of the pre~ent invention with a st~tio~electricity dissipa~ing Goating..
: In a~medic~l applica~ion, recepti~cle lO may serve a~
an autoclave receptacle `for containing medi~al ~n~trument~
during~sterilizatio~, and for maintaining sterility over a period of time. Thus f~r, tes~s have shown that sterility ~
a re~eptacle of ~he present inventio~ is maintainable up to 3~a~out l~O days. This sterilization re~eptacle ~Fi~s. 1, 2, , ~

material! such as ~ pliable plastic film 24 of from abou~ l to 5 mils thick, a~d which may be NYLON (TM), POLY~STER ~TM), or any other suit~ble sheet ma~erial having barrier properties such a~ to ~lock passage of dirt, dus~, and S microorganiSmS~ Further, the barrier material provides protection against liqui~s that may wet the fabric and possibly contamin~te o~j~cts therein. Ad~itionally, ~he barri~r mat~rial .~hould be sufficientlv rigid to le~d form and strength to the receptacle, whil~ generally conformin~ to ~o the shape of object~pla~ed inside.
A~ shown in Fig. ~, a plas~ic sheet ma~erial h~vina an adhesive layer 2l which becomes adhesively active with applic~tion of heat and pressure m~y be used, ~uch as a ~olyester laminate material distributed bv CREATIVE IMPRINTS
IS of Atlanta Ga. Otherwise/ an adhesive applied, as by a spray apparatus, either to the fabric or barrier material m~y be used ~o bond the f~ric and barrier materia~ ~o~ether. Thi~
b~rrier mater~al, when laminated or bonded to an interior layer of fabric 26 of r~ceptacle lO, has been found to ~o provide the necessary ~ua~iti~s ~ de~cribed above, in ~ddition to being puncture resi~tant. This i~ signifioan~ as me medi~al instruments have sharpened edges or points which, in the instance of certain sharpened and curved dental picks, may penetrate the inner layer of fabric and beGome ~entangled therein. Further, with the inner layer of fabric ~ onded to the ~arrier material, small cuts or breaks in the ; inner layer of fabric do not ravel, a~ the indi~idual broken ~hreads remain bonded to the plastic layer. Thi~ feature is 1' ~ i I ', in~trumental in maintaining integritv of the reGeptacles over ; 3O a~ least ~everal hundred sterilization GyGleS. In addition, i bond~n~ the ~nner layer o~ the receptacle t~ the barrier : material facilit~tes manu~aGture of the reoeptacles hy preventing the pl~stic layer from shiftin~ d~rin~ cutting and stitchin~ operation~.

DETAIL~D ~SCRIPTION OF T~E DRAWINGS
l~ Whlle a durable, reu~ahle recetacle 10 as shown in Fig. 1 i~ particularly desoribed in the pre~erred embodiments of this disclosure, it is t~ be appreciated that construction and materials of th~: receptacle may vary without departing : from the scope of ~his invention. A~ shown, recept~cle lO is obasically:a flat~ened pouch or bag stFucture closed on first, e~ond, ~nd third edges 12, 14, and end 16, respectively, with the ~ourth edge l~ being open. As such, article~
requiring:protection of one type or another may be placed in rec0ptacle IO, as~ illu~trated by a dental pick 22 ~dashed lines). Tn ~ddttion to medical instruments, a receptacle lO
: may be e~sily ad~pted for other purpo~es; for instance by constructin~ a proteotive carrier for electroni~ circuit boards by coating a receptaole lO of the pre~ent invention with a st~tio~electricity dissipa~ing Goating..
: In a~medic~l applica~ion, recepti~cle lO may serve a~
an autoclave receptacle `for containing medi~al ~n~trument~
during~sterilizatio~, and for maintaining sterility over a period of time. Thus f~r, tes~s have shown that sterility ~
a re~eptacle of ~he present inventio~ is maintainable up to 3~a~out l~O days. This sterilization re~eptacle ~Fi~s. 1, 2, , ~

Ad~itionally, ~he barri~r mat~rial .~hould be sufficientlv rigid to le~d form and strength to the receptacle, whil~ generally conformin~ to ~o the shape of object~pla~ed inside.
A~ shown in Fig. ~, a plas~ic sheet ma~erial h~vina an adhesive layer 2l which becomes adhesively active with applic~tion of heat and pressure m~y be used, ~uch as a ~olyester laminate material distributed bv CREATIVE IMPRINTS
IS of Atlanta Ga. Otherwise/ an adhesive applied, as by a spray apparatus, either to the fabric or barrier material m~y be used ~o bond the f~ric and barrier materia~ ~o~ether. Thi~
b~rrier mater~al, when laminated or bonded to an interior layer of fabric 26 of r~ceptacle lO, has been found to ~o provide the necessary ~ua~iti~s ~ de~cribed above, in ~ddition to being puncture resi~tant. This i~ signifioan~ as me medi~al instruments have sharpened edges or points which, in the instance of certain sharpened and curved dental picks, may penetrate the inner layer of fabric and beGome ~entangled therein. Further, with the inner layer of fabric ~ onded to the ~arrier material, small cuts or breaks in the ; inner layer of fabric do not ravel, a~ the indi~idual broken ~hreads remain bonded to the plastic layer. Thi~ feature is 1' ~ i I ', in~trumental in maintaining integritv of the reGeptacles over ; 3O a~ least ~everal hundred sterilization GyGleS. In addition, i bond~n~ the ~nner layer o~ the receptacle t~ the barrier : material facilit~tes manu~aGture of the reoeptacles hy preventing the pl~stic layer from shiftin~ d~rin~ cutting and stitchin~ operation~.

In a simplest embodiment of a closure of a receptacle of the presen~ in~ention, and as shown in Figs. 13a and 13b, a reoept~cle is constructed having an opening 37a which is J~ sealed by autoclave ~ape 33. In this embodiment, the auto~l~ve tape ~erves as th~ olosure.
