CONTAINER WITH RECLOSEABLE, COLLAPSIBLE POURING SPOUT BACKGROUND OF THE INVENTION Previous development of the container art, at least insofar as containers for the packaging of various and sundry liquids has progressed in the direction of providing containers with self-opening means. Further, certain of these containers are adapted with pouring spouts that are affixed to the container in some fashion to facilitate the dispensing of the contents from the container. Moreover, containers are now provided with a combined opening means and pouring spout, whereby upon lifting or disengaging the opening means from the top of the container, a pouring spout secured to the underside thereof is withdrawn from a nested position within the container. After withdrawal of the pouring spout, the opening means are removed from the pouring spout so as to permit dispensing of the contents of the container. The opening means have been taught to be threaded closures and also have been taught to be means that are secured to the top of the pouring spout which are removed by tearing at the top of the upward movement of the spout by continued movement of the opening member.

Containers such as mentioned above are intended for use in the storing and dispensing of oil, hazzardous chemicals, fuels, and other household and industrial compositions. As such, an independent opener and/or spout is no longer requiredfor use with the type containers previously described. Moreover, while certainly these prior art containers are an advance in the art, deficiencies are still present. These deficiencies are based on the fact that once opened, the existing containers cannot be conveniently reclosed in such a manner as to prevent spilling and/or evaporation of the contents from within the container before further need at some later time.

The present invention has further improved the container art by providing a container having a collapsible pouring spout that nests within the container and may be withdrawn from within the container to a pouring position. At the end of upward extension of the pouring spout, the cover means are torn or otherwise removed from the top thereof to permit dispensing ofthe contents. The cover for the pouring spout, however, after removal, has integral therewith, a friction or otherwise engaging cap from the pouring spout, whereby if only a portion of the contents are needed,the pouring spout can be tightly reclosed and the contents saved for future use. In fact, the recloseable cover of the present invention even permits recollapse of the pouring spout to its original nested position.

The prior art, though teaching containers with retractable pouring spouts having opening means associated therewith, is deficient in teaching or suggesting a pouring spout having a cover therefor which, once removed, provides a rescaling cap for the pouring spout. In this sense, the prior art is exemplified by Wells, US. Pat. No. 2,533,305; Kuss, US. Pat. No. 2,685,385; Rieke, U.S. Pat. No. 2,895,654; Winstead, US. Pat. No. 3,042,271; Chlystun, U.S. Pat. No. 3,298,577; Peace, US. Pat. No. 3,326,421; Booth et al, U.S. Pat. No. 3,481,515, and Kelbch, US. Pat. No. 3,502,246.

SUMMARYOF THE INVENTION It is an object of the present invention to provide a container having a self-contained, self-opening, recloseable pouring spout.

A further object of the present invention is to provide an improved dispensing container for liquids having a pouring spout nested therein prior to dispensing.

Still further, another object of the present invention is to provide a container having a pouring spout associated therewith, said pouring spout having a recloseable cap removably secured thereto.

Generally speaking, the present invention relates to a container for packaging and dispensing liquids comprising side walls, a top wall secured to said side walls, a pouring spout'secured to said top wall and providing access to the interior of the container therethrough, said pouring spout being collapsible to nest within said container, and cover means removably secured to said pouring spout, said cover means and said spout being adapted for friction reclosing engagement after said cover means is removed from said spout.

More specifically, the present invention relates to a container for packaging and dispensing liquids such as oil, chemicals and the like, the container being selfcontained, in that, a combined cover and opening means is provided on the top of the container which, when lifted, also pulls a pouring spout from its nested position within the container to an extended pouring position. At the top of upward movement of the pouring spout, the combined opening andcovering means are separated from the top of the pouring spout to permit dispensing of the contents of the container. Further, the combined opening and cover means is designed to tear away from the pouring spout at a particular predetermined location, after which, the cover means has depending therefrom a flange that will provide a friction or snap engagement with the upper end of the pouring spout was to reclose the container.

I Depending upon the desires ofthe manufacturer, the container of the present invention may be manufactured in such a manner that reclosing is accomplished by the flange residing within the upper end of the pouring spout; around the upper end of the pouringspout; in snap fitting engagement with a bead adjacent the upper end of the pouring spout; around the upper end of the pouring spout in friction engagement therewith, or the like.

Insofar as construction of the container of the present invention is concerned, the side walls, top wall, pouring spout and cover means may be molded as a unitary item. Additionally, the top, pouring spout and cover means may be molded separately from the side walls and affixed thereto. Likewise, the pouring spout and cover means may be manufactured separately and secured to the top wall in an opening therein, or the cover means may be molded separately from the pouring spout. As can be seen from the above, numerous variations are permissible for the construction or fabrication of the container of the present invention. When the side walls, top wall, pouring spout and cover means are molded as a single unit, the container of the present invention may be molded, then filled and a bottom wall secured thereto. Conversely, the bottom and side walls may be integral and the top wall and spout separated therefrom. The container could then be filled and capped with the top having the spout thereon. As such,

- DESCRIPTION'OF THE SPECIFIC EMBODIMENTS Referring to the Figures, specific embodiments of the present invention will now be described. A container generally indicated as 10 having side walls 12 and a top wall 14 is shown in FIGS. 1 through 3. Secured to the top wall 14 is a pouring spout generally indicated as 20. Pouring spout 2 0 may be integral with top wall 14 as shown FIGS. 1 and 2 or may be secured to top wall 14 in some manner as, for example, in an opening in the fashion indicated in US. Pat. No. 3,298,577 to Chlystun. In any event, pouring spout 20 may be designed in any manner so long as it will nest within "container 10 and can be extended to a pouring posi-- tion. For example, pouring spout 20 could be,designed to telescope into container 10 instead of flexing in accordion or some other fashion. For the purposes of this application, the term collapse refers to any movement or compression of spout 20 into container 10. As shown in FIG. I, pouring spout 20 is comprised of a lower flexible section 22 and an upper flexible section 24. As described hereinabove, pouring spout 2.0 is collapsible to nest within the container 10 as shown by wayv of example in phantom in FIG. 2. Accordingly, pouring spout 20 as shown in FIG. 1, to permit collapsing thereof, bends at areas indicated by 21 and 23 to become nested or recessed within container 10. Adjacent the top portion of pouring spout 20, as shown in FIG. 2, are a pair of

peripheral beads

26 and 28, said beads being separated by a weakened wall portion 29 that serves as a tear line. A cover means 30 is secured to the upper portion of head 28 of pouring spout 20. As shown in FIGS. 1, 2, 3 and 4, cover means 30 is integral with pouring spout 20 and has adjacent one end thereof an opening or gripping member 31 which is designed to receive a finger for lifting to open container 10. Practically speaking, with the container in the closed position, it is desirable for cover means 30 to be secured to the top wall 14 of container 10. Accordingly, cover means 30 is provided with a bead 32 which is provided to permit cover means 30 to be removably heat sealed to top wall 14 when the container is initially fabricated. As such, inadvertent opening of container. 10 prior to use is avoided. Also, removable securing of cover means 30 to top wall 14 holds spout 20 in the collapsed position until the desired time to dispense the contents therefrom.

Upon lifting cover member 30, heat seal 32 breaks away from top wall 14 and cover member 30 withdraws pouring spout 20 from within container 10. At the end of the extension of pouring spout 20 outside of container l0, pouring spout 20 breaks along tear line 29 so as to separate cover member 30 and bead or depending flange 28 from pouring spout 20. With cover member 30 removed, the contents of container 10 may now be dispensed through pouring spout 20. As mentioned earlier, it is often desirable to reclose a container after dispensing some, but not all the contents therefrom. According to the teachings of the present invention, pouring spout 20 may be reclosed as particularly shown in FIG. 4 by replacing cover member 30 over pouring spout 20. Bead or flange 28 now depending from cover means 30, is thus snap fitted into pouring spout 20 and held therein by bead 26. Reopening of spout 20 is thereafter accomplished by again lifting cover member 30 which will overcome the holding power of bead 26 and permit bead 28 to be pulled from within bead 26 of pouring spout 20. Container 10 is then readied for additional dispensing.

A further embodiment of the present invention is shown in FIGS. 5 and 6. FIG. 5 shows 'a portion of a container having side walls 112, top wall 114 and pouring spout 120. For all practical purposes, pouring spout is the same as spout 20 shown in FIG. 2 with the exception that in FIG. 5, head 126 is smaller in diameter than bead 128. Hence, upon upward movement of cover member 130 heat seal 132 breaks from top wall 114 and spout 120 is withdrawn from its nested position within container 110. At the top of upward FIGS. 7 and 8 illustrate still a further embodiment of the present invention wherein a container generally indicated as 210 is shown having side walls 212, and a top wall 214. As shown in FIG. 7, top wall 214 has a skirt 215 depending therefrom with an upturned portion 216 engaging an outwardly and downwardly depending lip 213 of side walls 212 so as to secure top wall 214 thereto. A pouring spout 220 is shown extending outwardly from the top of top wall 214 andbeing divided into a base section 222 and an accordion section 224. As with the pouring spout in the previous Figures, pouring spout 220 collapses to nest within container 210. As best shown in FIG. 8, the upper portion 226 of pouring spout 220 has a bead 227 around the top thereof. Additionally, cover means 230 is not integral with pouring spout 220, but is a separate component thereof. Cover means 230 is provided with a gripping means 231 and a cap portion 232. Cap portion 232 extends downwardly in annular fashion from cover means 230 and resides around pouring spout 220. Cap 232 has a skirt portion 233 depending therefrom and a weakened tear line 234 at the top of skirt portion 233. Skirt portion 233 is heat sealed or otherwise secured to the outer periphery of upper portion 226 of pouring spout 220 as indicated at 235 in FIG. 8. Once cover means 230 is removed from pouring spout 220, cover 230 assumes the appearance as shown in phantom in FIG. 8. Hence, cap 232 of cover means 230 normally resides around bead 227 of pouring spout 220. During opening of container 210, cover means 230 is grasped at gripping member 231 and lifted upwardly. Spout 220 is then withdrawn from its nested position within container 210 to its extended pour position. At the top of the extended position, cap 232 separates from skirt 233 at tear line 234 and is removed therefrom, thereby opening pouring spout 220 to permit dispensing of the contents of container 210. At the desired time thereafter, to reclo'se pouring spout 220, cap 232 is forced over bead 227 to again snap fit therearound.

Still a further embodiment of the present invention is shown in FIGS. 9, l0, and 11. In this embodiment, a container 310 is shown having side walls 312, and atop wall 314 having a pouring spout 320 associated therewith. Pouring spout 320 is shown in a nested position in FIG. 11. A cover member 330 is secured to the upper end of pouring spout 320 in any desired fashion as previously shown. In addition to cover member 330, pouring spout 320 also has a ring 335 secured thereto. Ring 335 is in normal position, as shown in FIG. 11, and is in a raised or lifting position in FIG. 11 in phantom. Hence, for withdrawing pouring spout 320 from its nested position within container 310, ring 335 is lifted as shown in phantom in FIG. 11 and pulled upwardly. The upward pulling on ring 335 thus withdraws pouring spout 320 from within container 310. Thereafter, once released, ring 335 again assumes the approximate 90 bend at the top of pouring spout 320 as shown in FIG. 11. As desired, after pouring spout 320 is in the extended position, cover means 330 are pulled upwardly to separate cover means 330 from pouring spout 320 and thus permit dispensing of the contents of the container therethrough. As described above, the relationship between pouring spout 320 and cover means 330 should be such that pouring spout 320 can be reclosed as desired.

Insofar as materials of construction are concerned for the container and parts thereof according to the teachings of the present invention, plastic may be used exclusively or used in conjunction with metal. Insofar as the plastic is concerned, there are no critical limitations other than that the composition should be inert to the contents of the container and should possess sufficient flexibility in the pouring spout to permit collapse and withdrawal of the spout into and out of the container. Also, while certain specific embodiments have been described above, one is not restricted to the particular designs illustrated. The various types of recloseable cover means may be interchanged with the various types of collapsible spouts. Additionally, when the pouring spout is in the collapsed position with cover means affixed thereto, the cover means may rest within a depression in the top wall so as to be flush therewith or may rest on the top wall and extend thereabove.

Having described the present invention in detail, it is obvious that one skilled in the art will be able to make modifications and adaptations thereto without departing from the scope of the invention.
