Dec. W53 H. @AUST INSULATED HANDBAG Filed June 2, 1952 IN VEN TOR.

DAusT HERBERT Patented Dec. 8, 1953 UNITED STATES PATENT OFFICE INSULATED HANDBAG Herbert Daust, St. Louis, Mo.

Application June 2, 1952, Serial No. 291,200

Claims.

temperature maintenance of articles disposed within the bag.

The handbag of my invention has a top opening and a slide fastener or Zipper for closing the same, and the lining members adjacent the opening are associated together in an improvedv manner so as to afford a smooth, semi-stiff throat portion which facilitates the insertion and removal of articles and whereby engagement of the lining in the Zipper teeth is prevented.

Another object is attained in improved provisions for reenforcing and maintaining the shape of the handbag, particularly at its upper portions which receive the greatest wear by reason of handling, and for securing in proper position and affording protection for the layers of insulating material. The means of my invention renders practical the use of bre glass as insulating material for thehandbag, which material has properties that make itl highly desirable for this purpose but which heretofore, because of its low mechanical strength, has not been satisfactorily so used.

In the drawing, Y

Fig. l is a perspective view of a handbag embodying the features of my invention;

Fig. 2 is a sectional view taken at line 2 2 of Fig. l;

Fig. 3 is a sectional view through a fragmentary end portion of the bag, as indicated by section line 3-3 of Fig. l;

Fig. 4 is a side view showing the lining assembly, and

Fig.k 5 is a sectional view through the upperV part of the lining assembly, as indicated by line 5-5 of Fig. 4.

The reference numeral i il designates the handbag which is seen to comprise a generally rectangular body having a carrying strap li attached to the top end portions thereof. The bag body is made up of an outer or covering envelope of fabric or plastic sheet materialv suitably cut and stitched to form sides I2 and i3,

panels i2 and I3, and by the tape members 20 and 2i of a slide fastener or zipper type of closing unit, indicated generally at 22.

The bag is provided with an insulated lining sack which is secured along its upper edge to the downwardly turned top margins of the side panels and the fastener tapes by rows of stitches 23. The lining sack is unattached of the outer covering at all other points and accordingly it can be turned inside out by drawing it outwardly through the bag opening, so as to expose the lining surface for cleaning and airing. The lining assembly includes a pair of vmoisture resistant side portions 2d and an intermediate partition member 25, all preferably formed of plastic sheeting, a pair of insulating pads 26 consisting, in the present example, of relatively thick layers of libre glass wool, and a pair of stiffener panels 21 of card-board or the like.

In assembly the upper marginal portion of each lining member 2t is folded over the top edge of one of the stiffeners 21 and is securedthereto by means of glue or cement 28 (Fig. 5). In this manner the liners 24 are bonded to the stiifeners throughout a marginal area which extends for a distance of one-half inch or more below the top edge.

The insulating plies 26 have their upper portions disposed between the liners 24 and the stiffeners 21, and have their upper edges spaced well below the top edge of those members. The insulating plies are secured by stitching 29 to the stiffeners.

At the end edges of the lining assembly the l paired lining members 2li and the intervening partition 25 are stitched together as indicated at 30, Fig. 3, the end edges of the insulating plies 2i preferably remaining unsecured. At the bottom edge the liners, partition and insulating plies are all stitched together as indicated at 3|, Fig. 2.

From Fig. 2, it is apparent that the stiffeners 21 are normally angularly related to the outer envelope or cover and to the insulating plies 26, the stiffeners 21 being extended outwardly and downwardly for a distance beyond the insulating plies 26.

' the cover in considerably spaced relation to the ends i4 andl5 and a bottom i6. The side and insulating plies 25.` It will be noted further that i the angularly related stiffeners 21 serve to maintain and realize enclosed insulating air pockets between the cover and the insulating plies 26 The outwardly and downwardly eX- tending portions of stiifeners 21 tend to retain Where padding of bre glass or other material having highfinsulatingfand cushioning value but relativelysmall mechanical strength is used the members 21 are especially desirable to provide reenforcement and protection for those upper parts which are most frequently handled and Sub-v ject to the greatest Wear.

I have described my invention with referencey to a particular handbag but it will be understood that the invention is not limitedV precisely tothe' form of the bag herein shown and described, nor e formed o f thin, exible, waterproof material, ad`

hesive means bonding the uppel` marginalpor.- tions of said liner to said reenforcingfmeans, thereby effecting a stiffening of the throat portion of said liner, an intermediateinsulating layer disposed adjacent the liner and consideru ably spaced from said outer covering, and means securingthe upper edges of said insulating layer to'said reenforoing means, the reenforcing means being normally angularly related to and projected for a distance outwardly of said insulating.

layerso as to tend tohold the outer covering spaced relation to said insulating layer to provide an insulating air pocket.

2,. A handbag Comprising a covering of pliable sheet material formed to provide top, bottom, side and end wall portions, said top wall portion hav.- ing anl .opening extending substantially the full length thereof, slide fastenerclosure meanssecured to thetop Wall portion along the marginsV of .said opening, reenforcng members of relatively'stii sheetmaterial secured to the covering topY wall at the edges of said opening, a sack-Alike liningmember of flexible sheet material,A adhesive; means securing together theupper surface portions of said reenforcing and lining members, and an intermediate layer of insulating material,v said intermediate layer having .upper end portions arranged in under-lapping relation to said reenforcing panels, .the upperend portions of said intermediate layer being secured to said reenforcingY panels in spaced relation to-.the connected upper surface portions of said reenforcingv and lining members and said covering.

3- -A handbag of the character described com-1 pllsingan outer eoveringcf` pliable materiall havins-an opening extending substantiallyithe fullLA length.-.of..the-top ofthe bag, andslide fastenert means .for-.",1osine said opening, a sack-like 1in.- ingassembly disposed within said covering andv secured thereto along the margin of said opensaldi lining assembly comprising paired liner members of relativelythin Waterproof Sheet ma terialiastened together. along their end and bottom edges, a pair of stiifener panels adjacent the.

outer upper A`surfaces of said. lining members,l the outer surfaces considerably spaced from the covering, said' stiffeners beingY normally disposed in an angular relation tov-said covering fand said insulating members, said stiffeners tending to hold the covering from engagement with said insulating members.

4. In a handbag of the character described, a covering layer of pliable sheet material, said covering layer having an opening therein and slidefastener` means for closing the same, a pair ofreenforcing members formed of relatively stiff sheet material, said members being secured along upper edges to said covering layer at .the opposite margins. of said opening, a sack-like inner lining formed of exible, waterproof sheet. material, .the upper marginal portions of said lining sack being folded over the top edges of said reenforcingV members, adhesive means vsecuring together adjacent upper marginal portions of said reenforcing members and said lining sack whereby to provide a stiffened throat portion for the lining sack, an insulating layer envelopiugsaid lining'saol; and secured, at upper edges thereof, 'to the inner sides of said reenforoing members below said stiffened throat portion, the

reenforcing members being extended angularly.
