Patented Mar. 18, 1952 COMBINED SIFTING AND POURING sPoUT Milton H. Klausmann, Maplewood, N. J., assign'or to Seal-Spout Corporation, Newark, N. J a corporation of New Jersey Application November 4, 1950, Serial No. 194,133

This invention relates in general to containers or receptacles of the type wherein a combined closure and pouring spout is connected to one wall of the container for movement relatively thereto so as in one position to serve as a closure for a'pouring opening in said wall and inanother position to serve as a spout for pouring the contents of the container through said opening. A pouring spout of this character usually comprises a-body portion of a size and shape to close the-pouring opening in the container, and integral sector-shaped side wings projecting approximately at right angles to the body portion that slide into and out of said opening in frictional engagement with the walls thereof as the spout is actuated to close and open said openings. I

A prime object of the invention is to provide a novel and improved combination of a pouring spout of this character and a sifter so related to each other and to the pouring opening of the container that the contents of the container selectively can be poured or sifted through the pouring opening.

Another object of the invention is to provide such a device which shall include a simple and reliable combination of only two parts one of which constitutes a screen whereby the contents of a container to which the device is attached can be poured directly in a stream through the pouring opening or shaken or sifted through said screen.

Other objects, advantages and results of the invention will be brought out by the following description in conjunction with the accompanying drawings in which Figure 1 is a top plan view of a pouring spout and container embodying the invention showing the device in closed position;

Specifically describing the illustrated embodiment of the invention, the-reference character the ' I designates the body portion of a container at one end of which is a cap 2 forming an end wall.

The container may be formed of any suitable material such as cardboard, fiber board, or the like, and one wall of the container, usually the end wall 2, is provided with a substantially rectangular discharge aperture 3 and a tab 4 integrally connected to said wall at one end of the aperture for hingin'gmovement into and out'of the opening for a purpose to be described.

Cooperating with the container I is a pouring spout 5 hingedly connected to the wall 2 at one .end of the opening so as to overlie and close said opening when in one position and to uncover oropen said opening when in another position. The spout is preferably formed of thin sheet metal bent upon itself to form a fiat body portion 6 and sector-shaped side walls I at the" side edges of said body portion that have arcuat'eouteredges 8 concentric with the axis of swinging ofthe spout. -The spout is of the same width as the aperture or 'opening 3 so as to frictionally engage the outer faces of the side walls I with .the side edges of said aperture, and the body portion 6 at one end overlies the tab 4 and at its other end has an extension 9 beyond the corresponding end of the aperture 5 for a purpose to be explained. The spout may be hingedly connected to the wall 2 in any suitable manner but as shown, a pair of prongs or teeth l0 pro- J'ect from one end of the body portion 6 through the wall 2 and are bent or clinched so as to permit swinging movement of the spout and at the same time prevent the spout from being pulled out of the opening 3. As usual the outer ends of the side walls or wings I are provided with lugs II to engage the underside of the wall 2 for preventing swinging movement of the spout outwardly of the opening 3, the extension 9 limiting ing and of the plate l2 may underlie the body portion 6 of the closure-spout when the latter is in its closed position, shown in Figure 6, and the plate I2 is of such length that its other end may project beyond the corresponding end of the opening 3 so as to completely overlie the opening asshown in Figure 6; With this con-"- struction, it will be seen that the screen or plate I2 can be swung about the tab 4 as a hinge so as to overlie the opening 3 as shown in Figures the plate I2 in overlying relation to the pour-' ing opening 3 may be provided, such as protuberances l5 in the flanges M to engage the inner side of the end wall 2 of the container.

in operation of the device, normally the plate 12 and the spout 5 will be arranged in overlying or closing relation to the pouring opening 3 as shown in Figures 1, 2 and 6. Should itbe de-' sired to sift or shake the contents of the container through the pouring opening 3,- the spout 5 may be swung-out of the opening and away f -rom the plate l2 asshown in Figures 3, 4 and 7. Dur ing the outward movement of the spout,- the plate I2 will be held against movementby the stop protuberancesf. 15. Then by inverting the eentainer and shaking it, the contents will be sifted or sprinkled through the'apertures of the plate I 2; Should it be desired to pour the contentsof the container freely through the; opening 3, both the spout and the plate I! may be'swung outwardly away from the opening 3 as shown in Figure 8. This operation can be easily effected by applying lifting pressure to the free end of the plate 42,

said pressure swinging the plate l2 and through contact of the plate with the body portion; of the spout, also swinging the spout at the same time; Similarly both the plate I2 and the spout may be swung into closed position simultaneously by pressure: against the body portion 6 of the spout tending to force the side walls 1 into the opening; It will be observed by those skilled in the; art

that the device embodying the invention is adaptable to containers for either powderedor granular materials, it being possible? to use the ,moved out of the way for pouring granular materials through the pouring opening 3.

While the now preferred embodiment of the invention has been illustrated and described, it should be understood that the device may be used with other types of containers and may be structurally varied; all within the spirit and scope of the invention.

I claim:

The combination with a container having a substantially rectangular discharge aperture in one wall thereof, of a tab hingedly connected to said wall at one end of the aperture for swinging movement into'and out of said aperture, a pourin'g spout hingedly connected at one end to said wall adjacent the hinging of said tab to open and close said aperture and comprising a body portion overlying said tab with one end portion adapted to project beyond the free end of said tab and the other end of said aperture for engagement with said wall in the closed position of the spout to limit closing movement of the spout and to seal said outer end of said aperture; and sector shaped side walls on said body portion hav-' ing their outer faces'frictionally engaging the side.

edges of said aperture to seal said edges in the closed position of said spout, and a perforate sift: ing plate fastened at one end to said tab for movement therewith to cover and uncover said for engagement withsaid wall when the'plate is in position to cover said opening, saidplate also having side flanges frietionally engagingthe side sifting plate l2 alone for dispensing powdered 5g materials, and the dispensing plate; being easily walls or said s out to form a seal between said plate and said spout.
