Douche fbags have become a matter of notessity, according :to modern standards of gfceminin hygiene, :to :suchextent that ithey are generally considered. a necessary implement even durin travel. "To :this end, manufacturers theme striven to make the bags in -:s'uch :manner that they may be easily stored in .a :minimum 20f :SDHCB. Despite such facilitation, however, and. for various :reasons, it quite frequently happens that a misty Jfinds herself embarrassed rfqrzneedotone of these items when away ztrom :her domicile. finsuchia case, it is not :a welcome :solutionito purchase :an

It is, therefore, an object of the invention to provide a syringe which is .low in :cost, so :as eto:be disposable after a :single use. .A further olaiec'tjis to provide "a syringe which may zbe consolidated into a comparatively small volume cfor carrying urposes andeasyzmerchandising.
A still further :object is-to zpronide forvassyiringe having easy manipulation whereby filling iscfacilitated and. positive (closing of the ,diller .opening is easily accomplished, permitting evacuation of the bag byrmanualzpressure (thereon.
These and other objects, which will be -apparent, are attained by the invention, -:a preferred form of which is described in the accompanying specificatiim and illustrated in the vdrawings, :in

:01 mani ulation t sw ngs :in ejecting the ailm ts, ,it is desira-ble a .hqkinesm ms he provided .for the tube 3 I! in its folded condition. Any simple clip, or a rubber band, may be adequate for this purpose. However, as a widely used commercial product, the syringe should be complete and fool-proof. A preferred form of clasp, as shown in the drawings, comprises a special form of rubber band in cooperative relation with a pair of knobs 29 on the ring 28 having neck portions 3| to receive the rubber band and prevent too easy removal thereof. The rubber band, which may be cut by conventional methods from specially extruded stock, has two outer loops 32 and a small central. loop 33, the latter being of a size to ensure retention on one of the knobs 29. With the central loop thus mounted, and the tube I 9 in folded condition, the outer loops 32 of the band are grasped by end tabs 35 and stretched across opposite sides of the ring 28 so that each may be looped around the opposite knob. This prevents unfolding. As sold, the bag will contain a watersoluble antiseptic substance 34 and, therefore, the package will be shipped with tube H! in the folded and secured position shown in Fig. 6. Sale of the package with the tube thus folded is of further advantage in that it clearly instructs the user as to the manner of closing and securing the filler opening.
With the nozzle 22 and powder 34 in place, and tube l9 sealed off, the nozzle is folded upon the bag to prevent outflow of the powder. Further folding of the article to provide a minimum of volume for placement in an outer container of wax paper or the like may be accomplished in any convenient manner. The volume of the article when folded will not be much greater than the combined volume of the nozzle 22, ring 28 and powder 34, the actual volume of the plastic bag itself being small.
While a certain preferred form of the invention has been shown and described, the same is not strictly limited thereby, since certain changes in the exact shape, form and arrangement, for instance, of the various parts, may be resorted to without departing from from the spirit or scope of the invention as defined in the appended claims.
