L. HESCHER, MAIDEN NAME IBAUMANN CLOSURE Filed May 14, 1932 Patented Aug. 27, 1935 UITED STATES dans cLosURE Lotte Hescher, maiden name Baumann, Frankfort-on-the-Main-Wiesenau,

Germany, as-

signor, by mesne assignments, to Harry L. Worthington, San Francisco, Calif., doing business as Worthington Laboratories Application May 14, 1932, Serial No. 611,408 In Italy September 10, 1931 9 Claims.

The invention relates to a closure for the closing of liquid, airor gasproof receptacles made of rubber, rubbered or other material, such as for example ice bags, hot water bottles, water pillows,

5 tobacco pouches and bags in general that are intended to receive objects and to protect them against water or moisture, for example when bathing, in rowing sports or water sports in general which consists of a tube-like lling and draining member that is made of a waterproof material such as rubber or the like, and which may be rolled up from its free end, and as a whole or partially is provided over substantially its width with one or more inserted or superposed parts made of a suitable `material such as of soft metal sheet, wire netting made ci soft metal sheet, or other suitable wire gauze, being made up either of one or of several parts, and serving to maintain the said tube-like filling and draining member in its rolled up position.

The inserted or superposed clamping part or clamping parts may project over the tube-like filling and draining member either at the sides' or at the lower end or at both, so that, in the one case, the tail-like end will come to lie on top of the uppermost layer of the rolled up tube-like draining and filling member, and thus act against the forces that tend to unroll the latter.

The iilling and draining member together with the inserted or superposed clamping part take preferably a shape that tapers towards the top with the object of completely enveloping the inner layers of the filling and draining member by the outer layers and to press them over their entire width tightly together so as to ensure an efiicient closing of the receptacle.

Easy rolling up and safety against unintended unroiling of the layers is obtained by lengthening one of the two wall parts of the tube-like lling and draining member that come to lie ilat upon each other beyond the opening of the receptacle, and by providing over the Width of this prolongation a roller-like reenforced part made `of the same material as the tube-like filling and draining member so as to form a core around which the layers of the said filling and draining member may be rolled up. The central position of this roller-like reenforced part provides an eflicient check against the forces that tend to unroll the layers, since thistendency of unrolling will show itself especially with the inner layers.

The tube-like filling and draining member may, with not too broad and comparatively small bags such as generally serve to receive objects when bathing, rowing or in other water sports, be made (Cl. 15G-3) of a width that corresponds with the width of the bag itself as in this case, there is no necessity for a restriction in width.

The accompanying drawing shows by way of example one method of how the invention may -5 be carried into eiect.

Fig. l shows a iront View of an ice bag with an open not rolled up tube-like filling and draining member that, in one of its wall parts that comes to lie flat upon the other, is provided with an inserted clamping part that is made of a thin and soft metal sheet;

Fig. lo, is a section through the filling and draining member on the line A-B of Fig. l;

Fig. 2 is a front view of the ice bag with the iilling and draining member rolled up;f

Fig. 3 is a perspective view of the rolled up filling and draining member.

Figs. 4, 5, and 6 show certain modiiications and have longitudinally divided clamping parts made of soft metal sheet and inserted into one part oi the iilling and draining member a roller-like reen'forced part being provided at the openingof the receptacle.

Fig. 4 is a iront view of one wall of the filling 25 and draining member into which the clamping part has been inserted;

Fig. 5 shows a longitudinal and Fig. 6 a transverse section through the filling and draining member, whilst Fig. '7 is a front view of the rolled up closing funnel.

In Figs. 1 and 2 the ice bag that is made of rubber, rubbered or other material is denoted by a and its tube-like filling and draining member that is made of the same material by b. The walls of the iilling and draining member fold longitudinally and the two wall parts come to lie iiat upon each other. One of these wall parts is provided with an inserted clamping part c that is made of a suitable material such as of thin, soit nonresilient metal sheet for example. On closing the opening of the receptacle, the wall parts of the` tube-like filling and draining member that lie flat upon each other are rolled up from the opening, as is made clear from Fig. 3. The inserted clamping part c in this embodiment covers almost the full width of the tube-like filling and draining member, and the latter as well as the clamping part taper in sire towards the top. The width of the inserted clamping part, and its form that appropriately suit that of the tube-like filling and draining member, guarantee an ecient and liquidproof closing of the receptacle. The clamping part may A be inserted or superposed on the tube-like filling and draining member in any suitable way, such as by vulcanizing or by any appropriate method. The clamping part that naturally can also be made of a non-metallic suitable material serves to maintain the tube-like filling and draining member in its rolled up position, and further special means may be provided to check the unrolling tendency of the said filling and draining member.

The special closing funnel that forms the object of the invention is easy to manufacture and provides a reliable closing of the receptacle. It is impossible for the rolledup iilling and draining member to open even if it is subjected to pressure from the exterior, as when serving as a seat or the like.

The forms shown in Figs. 4 to 6 are provided with two clamping parts d, e in place of a single one, which are inserted into the walls of the tubelike lling and draining member b, and which are fabric-covered and thus held together whilst they project towards the bottom beyond the iilling and draining member proper so as to form a tail-like extension d1 el. The double walled cover of the clamping part may be so made as to form a kind of bag with an appropriate opening through which the clamping members can easily be inserted or removed. The free end of the other wall part that carries no clamping part is fitted with a roller-like reenforced part ,f so as to facilitate'the rolling up of the filling and draining member on closing the receptacle. The clamping parts d, e of one part of the wall maintain the filling and draining member in its rolled up position in which the two wall parts come to lie upon each other. Eflicient closing of the receptacle is furthermore aided by the free tail-like part d1, e1 of the clamping part that, in the rolled up position of the lling and draining member, comes to lie uppermost and thus acts against the forces that tend toV unroll the said lling and rdraining member. The prolonged parts may be so arranged that they project over the sides instead of over the lower end of the filling and draining member, and may be folded over upon the upper layer in the rolled up state of the filling and draining member.

The longitudinally divided and inserted clamping part as shown in Figs. 4 to 6 presents over the one-piece clamping part the advantage of facilitating the opening and expanding of the tubelike filling and draining member, since these clamping parts at their adjacent edges yield veasily to every eifort and thereby facilitate the manipulation of the. bag.

I am aware that changes in the form and proportion of parts, and in the details of construction of my invention may be made without departing from the spirit or sacrificing the advantages thereof, and I reserve the right to make all such changes as fairly fall within the scope of the following claims.
