8 Claims. (Cl. 221-28) Our invention relates to metal containers, such as pails, cans and drums, arranged for containing liquids, and having at the top or side ,thereof a spout for facilitating pouring of the liquid from the container.
An object of the invention is to provide lthe container with an extendible spout which may be projected to a considerable distance from the container proper, yet need not be retracted or ll backed into the contents of the container when not in use.
Another object of the invention is to provide an extendible pouring spout which will permit discharging of the contents from the container, both in the extended and in the retracted positions of the spout, and regardless of the amount of liquid remaining in the container.
A further object of the invention is to provide a spout which may be extended fr'om the container in different curved and angular positions.
A still further object of the invention is to provide a device of the character described, in which all of the parts of the spout and the appurtenances thereof, including a means of insuring the admission of air to the container during the pouring operation, may be combinedand assembled in the form of a single unit and applied as such to the container Walls.
The invention possesses other objects and features of advantage, some of which, with the foregoing, will be set forth in the following description of the preferred form of the invention which is illustrated in the drawings accompanying and forming part of the specification. It is to be understood, however, that variations in the showing made by the said drawings and description may be adopted within vthe scope of the invention as 'set forth incthe claims.
Referring to said drawings:
Figure 1 is an enlarged longitudinal sectional view of the spout unit as applied to a container wall and showing the spout in an extended position for normal use.
Figure 2 is a view similar to Figure 1 but show- 45 ing the spout retracted and covered.
Figure 3 is a side view of a portionv of a container, with parts broken away to show the spout unit.
Figure 4 is a plan view of the container and unit as shown in Figure 3.
Figure 5 is a sectional ,view similar to Figure 2, but showing the unit as applied to a diierent form of container head. l
Figure 6 is a bottom view of the unit 55 tached from the container wall.
as de- Figure 7 is a vsectional view of a unit of somewhat modified design.
As illustrated in the drawings, the spout unit 2 is applied to a head 3 which forms part of a container 4 and has formed therein a discharge 5 opening 6 about which` the unit is disposed. In the embodiment of the invention illustrated in Figures 1 to Il, the head is formed with adiametrically extending upset portion 'I containing the opening 6 and defining on the inner side of l0 the head an inverted channel 8 which gradually decreases in width from a point adjacent one edge of the head and where the opening' 6 is located, to a point at or adjacent the opposite edge of the head. l5
'I'he spout unit, as here shown, is made up with what may be termed inner and outer necks 9 and I0 arranged in concentric relation and in registration-with the opening 6. The necks are formed with base portions each designed for iixed connection with the head, and desirably the base I2 of the inner neck vand the base I3 of the outer neck are arranged to be secured together and applied to the head as a unit. In the present form of the invention, a ring I4 is made part of the unit and such ring holds the-base I2 against the base I3 and forms with the latter the iiange of the unit wherewith'the cooperating ange I6 of the head is interlocked to provide anl effective seamed joint.
The inner neck is arranged to provide anextendible spout and is formed of a plurality of tubular sections I'l of which the base I2 may be' considered one section. The sections are formed progressively one of smaller diameter than the other 3 so that one may nest within another and each is tapered or otherwise formed so that the sections may beextended one from the other to an appreciable though limited extent, and when so extended the jointsv between the sections'will be substantially liquid-tight and the outermost section I1 may be disposed considerably outward from the base section I2 and with its outlet ori-` flce well advanced beyond the rim I8'of the container. The sectionsmay be made progressively smaller in diameter from' the section I2 to the section Il and thus arranged to surround the section I2 and when retracted or collapsed to lie in the space between the inner and outer necks 9 and I0, or as here shown, in order to permit greater facility in manipulation, the diameter of the sections decrease from the section I2 to section I1 to lie within the opening defined by the section I2. In keeping with the latter arrangement, the ring member I4 has a portion I 9 which extends partlyinto the opening 6 and provides a stop or support for the sections when the latter are retracted one within the other, or in other words when the spout is in collapsed position. Desirably the ring portion I9 is perforated or otherwise formed so that the free flow of the contents through the opening 6 will not be interfered with or the capacity of such opening restricted.
A full lip is provided along the outer rim of the section I1' so as to facilitate pouring of liquid from the spout without spilling or running backward along the sides of the latter. Preferably the lip 20 is made large enough to project over and cover all of the other sections when the spout is collapsed as indicated in Figure 2. Furthermore, the sections are preferably so formed and'de- 4 signed, that when in retracted position, the outer end of each of them will lie inwardly ofthe outer end of the outer neck I0, and thus when the sections are so disposed they will be completely shielded by said neck. A cap, 22, may be'positioned on and engaged with the end 2l whenl the spout is collapsed, so as to close the opening 6 and seal the container thereat.
It is important to note that with the device of our invention, no portion is required to protrude into the interior of the container, either in the extended or retracted positions of thespout. In this way, regardless of the amount of liquid in the container or the position in which the container is held during the pouring operation, the free flow of the liquid from the container will in no manner be interfered with. Furthermore, regardless of the depth of the container, the spout may be constructed so as to extend outwardly from the container head practically any amount desired. It is to be also noted that the portion of the base section I2 between the point of attachment of the head and the innermost point of engagement of such section and the next section when the latter is in extended position, is formed in a smooth curve from which the wall of said next section may extend in tangential relation. It will thus be clear that when the sections are extended as indicated in Figure 1, the liquid from the container may flow smoothly and easily into and through the spout. Of importance also is the fact that since the lower section I2 is formed as a fixed part of the container and extends outward therefrom to an appreciable degree, the smooth and free flow of the liquid can under some circumstances be permitted without extending the sections.
A feature of considerable advantage which arises out of the sectional design and of the manner of connection of the sections, is the exible nature of the spout when in extended position. By reason of this construction not only may the spout be extended in different angular relations to the head, but the spout may be extended in a curve so as to position the spout discharge orifice as defined by the lip 20 in considerable angular relation to the orifice 6 and well over the outer neck I0.
Preferably included as a part of the spout unit and arranged for application as such to the container head, is a means insuring the flow of air to the interiorfof the container as the liquid is being poured from the spout. As will be clear from Figures 1 and 2, the outer neck I0 and the base section I2 of the inner neck are spaced to define an annular chamber 26 which bymeans of an opening 21 at the bottom thereof is afforded communication with the interior of the container. i
In order that the chamber may have communication with the uppermost portion ofthe interior marginal portion 32, and when the spout is put .metrically opposite the opening 6. For the operative connection and attachment of the pipe to the spout unit, the portions of the base I2 and the ring I4 at the opening 21 are offset and the ring is formed with a laterally extending socket 29 in which one end of the pipe is rmly but desirably removably held. It will be understood that during the pouring operation, the chamber 26 is uncovered, and therefore the air may iiow freely thereinto and into the pipe during said operation. No restriction of the discharge opening i is entailed, and when the cap is positioned over the unit as in Figure 2, the opening 21 as well as opening 6, is closed and sealed. It will be noted that the channel 8 provides a shielded cav- 20 ity for the reception of the air pipe.
In the form of the invention, illustrated in Figure 5, the unitis simply positioned on the container head with axis of the `discharge opening 6 and of the spout unit perpendicular to the plane of the head. This arrangement avoids the use of the diametrically extending offset in the head, and any desired inclination or curvature in the spout for insuring ready pouring over the rim of the container is effected by flexing the spout u through appropriate relative positioning of the sections;
In Figure '1, a modified form of closing and sealing means is provided for the spout unit. As here shown, the upper portion of the outer neck I0 is extended to provide an integral cap or closure 3| which together with such neck forms a complete and sealed enclosure for the inner neck including the spout sections. The closure portion 3| is connected to the neck by a weakened into initial use the portion 3| may be -readily severed from the remainder of the neck so that the spout sections can be withdrawn and exitended from the enclosing rvck portion I2. Desirably the cap portion 3I in its position before removal from the neck, lies depressed below and inwardly of the rim of the latter so that upon the subsequent removal of the cap portion the rim will remain smooth on the inner side of the neck. A cover 33, designed for threaded engagement with the neck, is provided for closing and sealing the opening in the neck Awhen the cap portion 3| We claim:
