3 2,172,823 BAG sPoUT If, llfi llchard HfPi am naick er g wis, h ima maze, 1554, sensin 439,79 1! 1 e The present invention relates to dispensing spouts, and

more particularly relates to a dispensing'spont-for flexible bags to facilitate the pouring of material; from'rsuchb'ags. The primary object of the invention is toprovide a L foldable'dispensing spoiit adapted to" be mounted within flexible bags adjacent thejf tops thereof which spout may be easily and quickly unfolded to i ts pouring. position upon opening of the bag and which spout may beiolded back into the bag and "out of pouring position is desiredto close the spout;

A further, and highly important object of the invention, is in the provision of a flexible bag spout which is disposed entirely within the bag and which will in no manner interfere with the sealing characteristics of the bag when closed, which spout will readily unfold into its pouring position upon opening of the bag.

A still further object of the invention is to provide a pouring spout for paper, cloth and other type bags which necessitates no modification of the conventional bag to which the pouring spout of the present invention,

is attached;

' Figure 2 is a view of the bag with the top opened and the spout extended to its pouring position;

. the pouring spout serves as a guide for dispensing mate- 'In the packaging of fertilizer and other granular materials in heavy paper, cloth and other type bags, when such bags are opened for dispensing the contents t-herefrom, considerable difliculty is encountered .in pouring the contents into any specific. area, this difficulty being increased'when it is desired to pour the granular material, such as fertilizer, into a fertilizing attachment or into a utensil used to refill an attachment hopper. It is almost impossible to perform such operation with the ordinary bag without spilling a certain amount of the. granular material on the ground. V a In accordance with the present invention, aflexible ing a diagonal fold line on each spout section extending 7 or pliable bag 10 of a conventional nature is shown, sealed at its upper end as-by means of the stitchinglz.

Mounted within the bag is a foldable spout 14.

When the stitching on the top of the bag is ripped and the bag is opened, :as .shown in Figure 2, the spout 14. is extended or unfolded-to its pouring position toguide the contents of the bag as such contents are dispensed from the bag. n L .i T

The pouring s'pout14 is initially, as shown inFigure 4, in the shape of' a semi-elliptical blank,; the blank-haw; ing a longitudinal; fold line 16 along the :longitudinal or major axis thereof throughoutits length to' divide the same into'equalpoi'tions 18 'and 20. 1"?

The blank is also provided with a transver'sefold line 22parallel. to and adjacent theef st'raight edgeor minor axis 24 of the blank 14; IThetransverse. fold linedivides each of the equal portions 18 and 200i 'the blank1fin'to a rectangular section 26 and thep'ouring spout sectiondefined'by each of the portions'lfl and 20 bounded bythe fold line 22: andthe major' portion ofthe longitudinal The blank is furtherprovid ed' 'with a diagonal fold line 28 on eachiofithe Tspout'sections extending from the section of the longitudinal and. transverse fold lines 16.--and'. 22, respectively, to the peripheral edge of the' spout section dividing each spout section into inner and outer portions 30 and 32, respectively.

To fold the spout, the blank 14 is first creased along the longitudinal fold line 16 so that the outer portions 32 of the spout sections are brought into abutting relation with one another. Then, the inner portions 30 are folded in superposed relation on the abutting outer portions 32 and the rectangular sections 26 are folded on top of the inner portions 30 so that they are parallel to the longitudinal axis designated -by the fold lines 16 of the spout.

When so folded, the rectangular sections 26 comprise flaps which are attached by means of staples or stitching or the like 34 to the inner surface of the bag adjacent and parallel to the top of the bag.

Normally, when the bag is closed, the shape of the bag maintains the flap 14 in its folded position, as shown in Figure 1, which is somewhere between the complete folded position shown in Figure'6 and the partially opened position shown in Figure 3.

' Upon'opening ofthe bag and flexing. the bag for pouring, the spout 14 unfolds to its open position wherein may be resorted to, falling within the scope of the appended claims. 7

'What is claimed as'new is as follows:
