Application June 28, 1937, Serial No. 150,709 6 Claims. This invention relates to an improvement in dispensing ñttings for liquid containers and gen erally aims to provide a fitting of this character which is self-venting and also embodies the fea 5 ture of a disappearing spout. Another object of the invention is to provide a dispensing fitting of this character which is sim ple and durable in its construction, coinpactly organized, reliable and eflici-ent in use, easily il) manipulated, and easy and comparatively inex pensive to manufacture. . Another important object of the invention is to so construct and organize the nozzle and spout as to insure the effective operation of the scif “ venting feature in actual practice. Other objects `and advantages reside in certainnovel features of the construction, arrangement and combination of parts which will be herein after more fully described and particularly (Cl. 221-11) as indicated at I'I with the margin of the open ing in the top II of the container. A removable closure cap I8 of any suitable construction is provided for the nozzle I2. A disappearing spout designated generally at el. 29 is hingedly connected as at 2| to the outlet ñtting adjacent one end thereof so that the spout may hang downwardly in the can as illustrated in Figure 2 to permit of application of the closure cap I8, or may be swung upwardly and outwardly to the pouring position shown in Figure 1 when cap I 8 is removed. The spout 29 is generally U-shaped in horizontal cross section as» will be understood from the drawing, particularly Figure 3, and is made up of side walls or wings 22 15 disposed in spaced parallel relation and connected transversely at their forward ends by the curved 20 pointed out in the appended claims, reference end portion 23 of the spout. The spout is so shaped in vertical cross section that its side wings 22 and curved forward end wall 23 all have a being had to the accompanying drawing forming vertical portion 24 designed to snugly fit against a part of this specification and in` which: Fig. 1 is a fragmentary View in central vertical longitudinal section illustrating a portion of a 25 top of a container equipped with a dispensing ñtting embodying the invention and showing the spout in its extended or operative position; Figure 2 is a View similar to Figure 1 but illustratingl the disappearing spout hanging down 30 inside the container in its inoperative» position and showing a closure cap applied to the outlet fitting; Figure 3 is a, fragmentary view illustrating the dispensing fitting in top plan; 35 Figure 4 is a sectional view taken on line 4-4 of »Figure 1; and Figure 5 is a similar view taken on line 5-5 of Figure l, parts being broken away and parts being shown in elevation for the sake of illus 40 tration. Referring to the drawing the numeral I0 des ignates generally a metal container which m-ay be of any suitable construction and which is pro vided with a top I I, preferably inset in the man 45 ner indicated in Figures 1 and 2. Thetop II is provided with an oblong opening equipped with a similarly shaped nozzle designated ‘generally at I2. 'I'he nozzle I2 has a vertically disposed upper portion I3 provided around its upper edge with a rolled bead I4 and has an outwardly and downwardly inclining or'ñaring lower portion I5 formed as an integral continuation of the upper portion I3. The Haring lower portion I 5 has a horizontally 55 disposed marginal flange I6 which is interseamed the vertical portion I3 of the nozzle and a down wardly and outwardly daring portion 25 designed to snugly inter?it with the flaring portion I5 of the nozzle when the spout is swung to its pour ing position. Rigid lugs or ribs 2B are pressed out from or attached to the vertical portion I3 of the nozzle and are so positioned as to engage the curving edges 22’ of the spout so that as the spout is swung up to its pouring position these lugs or ribs will force the spout forwardly to cause it to firmly interfit with the portion of the nozzle with which it is associated. In other wo-rds, the spout is so designed, dimensioned and proportioned that its side wings 22 have tight OD 5 spring friction engagement with the inner wall of the nozzle as the spout is swung to its opera tive position. The major axis of the outlet nozzle is substan tially longer than the corresponding axis of the spout so that with the spout in its pouring posi tion there is a substantial venting space 30 rear wardly thereof. The hinge connection 2l is sufri ciently loose or “sloppy” to allow the ribs 26 to exert the camming action described. This ac tion of the lugs lplus the fact that the wings of the spout have snug frictional engagement with the outlet fitting releasably retains the spout in its pouring‘position. In this connection, it will be noted that the forward portion ofthe spout overhangs the bead I4 of the forward portion of the nozzle and when retained in this relation, will not drop back into the container. 'I'he spout, ‘ like the container proper is constituted of sheet metal and hence is possessed of the proper 2 2,129,819 forcing the spout into tight frictional engage amount of still resilience to enable it to be shaped as shown and yet retain its shape and function ment with the nozzle in the extended position of as described in use. the spout. 3. A dispensing fitting for containers compris An important feature of the present invention resides in the structure and organization of the spout and its nozzle to insure self-venting at all times and yet provide for the pouring of as large a stream from the container as is practically desirable. When a person tips the container to 10 pour liquid therefrom, the spout being in its extended or pouring position, there is available a spout of ample proportions to allow a stream of any practical or desirable size to be poured there from, this following from the substantial extent 15 of th-e side wings of the spout as well as its other dimensions. Moreover, there is a substantial space between the rearniost portions of the edges of the wings of the spout and the rear end of the nozzle so that at the rear of the nozzle there is 20 always a substantial venting opening. These fea tures, together with the fact that the extent of the spout and the extent of the venting opening are always within the full View of the person using the container, will of themselves preclude any 25 possibility of the container being so far tilted as to interfere with the eifective self-venting. In fact, this is practically impossible because any attempt to exceed the capacity of the. spout and consequently to obstruct the venting opening at 30 the rear thereof would, if made, result in spilling of the liquid. ing a nozzle secured to the container and pro jecting therefrom, said nozzle being of oblong form, a spout of generally U-shaped form hinged ly supported for pivotal movement with respect to the nozzle and adapted to hang inside the con tainer or to be extended through and beyond the nozzle, said nozzle and said spout having inter engageable vertical portions and also interengage able downwardly and outwardly flaring portions, and rigid camming lugs carried by the nozzle and co-operable with the rear portions of the spout to force said interengageable parts into tight fric tion contact. 4.
