WATER FILTER CARRYING CASE 1 Filed July 51, 1946 4 Sheets-Sheet 4 Dovld H. Quinn Patented June 28, 1949 UNITED STATES PATENT OFFICE (Granted under the act of March 3, 1883, as amended April 30, 1928; 370 0. G. 757) 4 Claims.

This invention is a continuation-in-part of my copending application Serial No. 666,939, filed May 3, 1946, and relates to improvements in the combined bucket and carrying case structure disclosed therein which is used with a portable water purifier.

One of the objects of this invention is to provide a flexible container serving as a combined bucket and purifier carrying case which is so designed that it will retain an optimum shape.

Another object is to provide said container with suitable means for carrying the instrumentalities which are employed in cleaning the purifier.

Another object is to provide said container with reinforcing means which also serves as a receptacle for a cleaning and regenerative compound.

Another object is to provide said container with a collapsible and foldable canteen and means for carrying the same.

A further object is to provide said container with simplified means for securing the various parts thereof in compact carrying case position.

Still further objects will become more apparent from a consideration of the description to follow, the accompanying drawings, and the appended claims.

Referring to the drawings:

Referring to Figs. 1 and 2, fabric container III comprises generally a bottom II, a somewhat cylindrical portion l2 extending vertically therefrom, an elongated flap 13 forming a continuation of the cylindrical portion and a hinged cover It, the various parts being shown in a position ready for scooping water from a suitable source. After the water has been scooped into the bucket, the portable water purifier I5 is inserted in cylindrical portion [2 and the water is pumped through the purifier by operation of handle Hi, the purified water discharging from effluent tube l1 into a suitable container, all as will be more fully understood by reference to the copending application previously identified. When the structure aforesaid is to be disposed in its carrying case position, flap I3 is wrapped around cylindrical portion 12 and hinged cover I4 is telescoped over the cylindrical portion as best depicted in Fig. 3. The general features so far described are common to both this disclosure and the application previously referred to.

In the previous application, the container is shown with a cut-out portion in one of the side walls. In this invention the top edge 2| of both side walls is constructed straight, that is, parallel to base II. This provides an increased bucket volume without increasing the overall dimensions of the container. Also, in the previous application, the lower portion 22 of fiap I3 is substantially parallel to bottom H, whereas in this invention it is disposed angularly thereto, this feature acting in a strut-like manner to aid in supporting the overhung load of water contained within the flap. If desired, the lower angular portion 22 may be reinforced by incorporating therewith a flexible material which is sufiiciently stiff to add support to the overhung flap 13 but sufficiently flexible to permit the flap to be wrapped around cylindrical portion 12. As examples, a resilient wire of metal or plastic material could be inserted within or adjacent seam 23. On one side of the container, two

vertical sheaths

24, 25 are provided, these being of fabric also, suitably secured to the container by stitching for example. A hole is provided in the bottom of each sheath to permit drainage of any water which might enter therein. Removable tubes 26 are inserted in

sheaths

24, 25 and serve to reinforce the container and also provide receptacles in which the cleaning and regenerating compound 21 may be carried.

The open ends of tubes 26 are sealed by plugs 28 pressed into the tubes and over these are placed caps 29 which tightly telescope over the outside of thert-ubes. Thesercapsmaywbe constructed.-of.=.cellophanecor the like which may easily be removed but provides an effective seal against entry of water or foreign matter. If desired, a partition 30 may be incorporated in tubes 26 dividing same into two compartments. This construction has the advantage that if one plug and cap is removed and a portion-ofthe-compound in one end of the tubeis xusedptheeentry of water or foreign matter into the remaining portion thereof will not affect the compound-in the opposite end of the tuba-thereby reducing the chance of compound spoilage after one of the tube seals is broken. While the tubes 26 may be constructed of any suitable material, a transparent plastic is well adapted to. the, purpose since it is light in weight, .sufficiently resilientto resist shock and .still. act..as a reinforcing means, and further, by reasonofitstransparency the amount of compound used in a cleaning and regenerating operation can :be easily. gauged. .Also, the reserve supply of compound can be readilyascertained.

.In-=distinction .to..the former application, this invention providesa single securing means 3| to retain-the various parts of .-the container in carrying case position. Securing means 3I, which is in the form of .a fabric. strap, has one end secured .ati32 toa-side. of. split cover I4 and its opposite end cooperates with buckle-=33 securedto the lower. portion ,of the container. Intermediate its lengthit passes through, a U-shaped member I34 secured to'thesadjacent side. of splitcover It. Thus .it may be. seen thatabya single securement at..buckle: 33, strap..3I pulls the splitcover to- :gether, pulls it downward to, resist swinging to its-open position and .since. strap 3| overlies "flap I3, the latter is secured in wrapped engagement with-the. remainder of the. container.

.Toprovi-de a. convenientmeans for carrying a canteen withthe unit,strap member'36 is securedat its.,.opposite endsto sheaths "24, '25, respectively, thereby forming a pocket structure into which aiolded canteen may be inserted. This pocket structure may be closed at'the bottom or left open as shown; hinge 31 acting as a pocket bottomtoprevent the canteen from sliding downwardly.

Within. the container in any ,convenient position, a pocket "38 'isgprovi'ded. into which'a cleaning'brush'39 may belinserte'd, 'this brush-being for thepurpose o'f brushingthe outside of the water purifier tubes when :being cleaned.

Referring to'Fig. S'the-canteen structure 40, which is adapted to' be folded and inserted in the pocketformed by strap'36, comprises a pair of rectangular side walls 4I,'a-spout 42, a carrying strap 43, and astrip 44 over'the spout mouth. The entire structure is preferablymade of a vinyl resin, and particularly the vinyl resin known by .the trade name Vinylite whichis a plasticized copolymer of vinyl chloride and vinyl acetate. This ,material [has been found satisfactory for the purpose, since'it' imparts no taste, color, odor,

.or toxinsto. the water, is 1ight;in weight,-trans parent so that thecondition of .the'inside or the canteenmaybe visually inspected, can be easily folded into .a compact package, and has somewhat unusual elastic characteristics in that it may bestressed.beyondtheisoacalled,elasticlimit and still resume its original form. Other ma- 4 terials such as vinylidene chloride and copolymers, etc. could serve the same purpose.

The side walls II of the canteen are bonded together along their edges as indicated by the dotted lines as by cementing, by use of a solvent which-will weld .the sides. together, or by welding by. heat and pressure. Alternately, the canteen body could be formed by a molding process.

..Spout 42 which may be molded as an integral piece has a collar portion 45 which is secured to the canteen-body in any convenient manner such as previously described. The strap 44, secured to thespout -serves to support the spout below the effluent tube I'I. iwhen used with the embodiment shown in Fig. 8a of the previous application, the telescopic effluent tube shown therein would be extended .and mouth .44 would be hung thereover so thabtheliquid discharged from the purifier would be directed downwardly into the spout. The strap. relievesthe operator from the necessity .of hold-ing the canteen spout under the ellluent .tube ieavinghim with one hand to steady the purifier and the other to operate the :pump handle. When water is'being transported in the canteen, carrying strap 43 is placed on a body belt such as a trousers .belt, cartridge belt or the like. 'fTo seal the spout it is folded back upon itself..and secured in that position by a suitable clip'EIl as illustrated in Fig. 8. .In emergency if theclip were lost,the spout .could be retained .in theposition shown in Fig.8 by. binding the fold withstring.

.Fig."7 shows a modified arrangement of the spout, thespout' in this case emanating laterally from the canteen body rather than longitudinally thereof.

.A modified. and preferred form of my container .is-showninFigsf9 through 13. Referring to these figures, the container portion I00 and. elongated .flap IOI have substantially the same configurations and serve the same functions as the containerportion I0 and flap portion I3 shown in Figs. .1 through 3. and described above.

On onesidepf the container,however, three vertical. sheaths IIO,'III, and H2 are provided.

These vertical sheaths extend the full length of the container and arepreferably fabricated of a .singlesheet offabric sewnv or otherwise affixed to the. sideo'f container Hill. The sheaths III] and H2 serve as repositoriesfor tubes26. As described above .in.connection with Figs. 1 and 2, .the tubes 26 will serve to reinforce the. container Hill.

The sheath III serves as a repository for a cleaning brush I I3 .and .thecollapsible canteen I l4..shown in Fig. 14.and described in detail below. The wire brush II 3 is inserted at the top of the. sheath. The canteen is inserted through a slot I [5. cut in the side of the sheath and preferablylocated approximately. midway the length thereof.

The container is provided with cover I20 se cured .tothe outside of sheath III by flexible hinge I21. .Thecover is split to form an inside flap portion"l.22 and overlapping outer flap portion I23. "Male portion I24 and female portion I25 .of a snap fastener are oppositely disposed .onflaps I23. and I22, respectively. A snap fastener female portion I26 is disposed on the inner surface of flap I.22 opposite female portion I25 and adapted to mate with a male portion I2? disposed on elongated .flap .IDI. The function of .these various snap fastener elements will be explained hereinafter.

A split flexible 'strapi'28 is affixed to the lower part of the container and is provided with male and female snap fastener elements I29 and In securing the various parts of the container in carrying case position, the flap IN is folded back around container portion I00. The ends of flexible strap I28 are brought together around the container and the snap fastener elements I29 and 139 secured to each other. The cover I is brought down around the top of the container and snap fastener elements I26 and I21 secured. Flap element I23 is then drawn tautaround the container and snap fastener elements I24 and I25 secured to each other, as shown in Fig. 10.

The collapsible canteen H4 is fabricated of the same materials as the canteen of Figs. 5 through 7. The canteen H4 however is provided with a carrying strap I afiixed to the top of the canteen, and a spout extending laterally from the side of the canteen adjacent the carrying strap. When the canteen is folded and inserted into sheath III through slot H5, the carrying strap I30 will extend outside of the sheath to facilitate ready removal of the canteen from the sheath.
