In the device selected for illustrationpthe syringe comp-rises a folding bag of rubber "of other plastic material carrying at its lower end a flexible tube; and it also comprises 'a' box or case which: in this instance is constructed of sheet meta-l, thebox being provided with a hinged top' lid or cover, a' body supporting the bag and ii'iithin'i which the foldedv bag can be disposed',- and a-hinged bottom or lower cover which in one poi sitfonrtansthe bag within they @dse and in an; other position per-mits the bag to-l-l'figf'down beil n drawings; the box or case siiidic'itd generally vat ID', the body at Il; the hinged/top cover at (I2, the hinged bottomA at I3, the bigrt it; medesime tufbj at ls, and the bzzre'atand has a refl'tivelyjshauow uddi.

The ends ofthe b 'odj ies IS areV provided `with flaredhollow or recessed iort'is so that the end portions of the rods can b'ebent to forrn an'ge'd clinching heads 22 by which the' rods are secured iii place, as' shown; feln example, in Fig. y5. At the topf of the bag' the sheetA rubber material is turned up'n itself to provide a part 22a like a hem at the sides and ert'isI of the bag, which is provided at each end Witha through opening E3 in' which the correspondng rod body and its associated sleeve are closely tted: In" this manner the bag at its front' and rear edges at the mouth thereof is se-l cr'ely Amounted uponv the respective attaching rods.

At the forward edge of the bag mouth the at; taching rod l1 has the end portions of its body extending through perforations in the side walls of the'case body, and the rod body is clinched against' the' outer faces of said side walls. lin the ose' of thel -rod |18,however, the rod is utilized in providing a hinge between the lid I2 and the case body. For this purpose the lid I2 is provided with downturned side flanges 24 which adjacent the rear end of the lid are extended to provide hinge lugs 25 positioned outside of and against the side walls of the case body, and these lugs are provided with perforations registering with perforations in the side walls, and the rod body I9 extends through these perforations and is clinched against the outer faces of the lugs 25 in a manner such that the rod body le is rigid with the lid and swings with the lid when the lid is opened and closed.

Preferably the upper edge of the case body is turned inwardly on a gradual curve, as shown at 26, along the sides and ends of the oase body so as to overhang the mouth of the bag to a certain extent and thereby inhibit the spilling or leakage of liquid being poured into the bag.

The lower cover or bottom I3 is provided with side flanges Z'l and with hinging lugs 28 corresponding to parts previously described, and the lugs 28 are outside of and against the side walls of the case body and are hinged by means of short rivet members 29 extending through registering perforations in the hinge lugs and the side walls.

Each of the covers I2 and I3 is provided with a flange 30 at the forward edge and a flange 3l at the rear edge of the same depth as the flanges 2d and 21 except for a fastening portion 22 hereinafter mentioned. The hinge lugs 25 and 28 project laterally beyond the flanges 3i, and when the covers reach the positions shown in Figs. 2 and 4, in which they are vertically disposed, the

flanges 3| have their edges come into engagement with the rear wall of the case body through the length of said wall so as to provide stops. These stops come into action when the cover is swung into a position in which it is at right angles to the body.

The fastening portion 32 of the lid flange, mentioned above, is of somewhat greater depth than the remainder of the flange and is downwardly sloped toward a point at the lower edge, and is provided with a lower tip 33 adapted to contact and ride over a small rivet 34 applied to the front wall of the case body, and there is a frictional interlock between the head of the rivet 34 and a surface of a cup-like recess 35 at the inner part of the fastening portion 32. By this construction an effective snap fastening is provided between the cover and the box body which will hold the cover in the closed position in an effective manner, although permitting convenient opening of the cover when that is desired.

The upper lid I2 is provided with a suitable opening or aperture 36 to be engaged by a nail or hook on the supporting wall, and in use the device has the position shown in Figs. 1 and 2. When in this position, the bag can be lled with a liquid and used in the customary manner. It is important to note that in this position of the parts the case body is strongly braced by the engagement therewith of the upper and lower lids in the manner described above. Therefore, the case body, when the bag is filled with liquid, will not be displaced so as to take a position in which liquid will be spilled out of the bag. After use and removal of liquid from the bag, the device can be readily folded to place it in condition for transport or storage, in which condition the case contains the operative parts and has the appearance shown in Fig. 6, the bag being folded within the case, and the tube together with the pipe I5 and/or other appliances being stored in the case under the folded bag. Before folding the bag, the pipe is removed from the tube, the bag folded at the lower part so as to be stored within the lower part of the case body, and the tube disposed in the bottom of the case body in a convenient manner.

The mouth portion of theibag is of such dimensions that along the sides and ends it is overhung, at least in part, by the inturned edge at the upper part of the case body, and the cross rods are set into the case body so as to be very closely adjacent the front and rear walls of the latter, the result of this arrangement being that the leakage of liquid over the upper edges of the bag, and between the bag and the walls of the case body, is inhibited. The cross rods are permanently connected to the case body, and thereby the bag is permanently connected to it so that there is no difficulty occasioned by the misplacement or loss of the bag element, which is at all times ready for use. The bag mouth lls the case body near the upper edge of the latter, so as to extend substantially from side to side and from end to end. The case body, with its enclosed bag, is strongly supported from the supporting wall through the media of the upper and lower covers in a position in which the case body extends at right angles to the wall.

The construction used for hinging the upper lid is of the most simple and effective kind, the rear cross rod serving as a part of the hinge, thereby reducing to a minimum the number of separate parts used in the assemblage. The hinging axis is near the upper edge of the case body and close to the rear wall of the case body, but within this wall, and is coincident with the axis of the adjacent cross rod.

While the enclosing case for the article is shown A as constructed of metal, other materials, such as plastic material, may be used for this purpose. In any event, the case is preferably relatively rigid so as to serve as a protection for the contents. The case not only protects the syringe parts, but serves to prevent clothing and the like from coming into contact with moisture remaining on the syringe parts after use.

Various modifications and changes in the details can be made without departing from the principles of the invention or the scope of the claims.
