4 Claims. (Cl. 222-455) The present invention relates to containers for finely divided material, and has special reference to cardboard cartons for detergent powder or other nely divided material for household use.

The principal object of the invention is to provide a container of this character having novel and improved means for dispensing the contents thereof .in measured quantities.

Another object of the invention is to provide a container in which such dispensing means is so constructed that it does not add materially to the cost of the container.

The invention is illustrated, by way of example, in the accompanying drawings, in which:

Figure l is a view in perspective of an upper corner portion of my improved carton in its preferred form;

Fig. 2 is a sectional view taken on the line 2-2 of Fig. 1;

Fig. 3 is a sectional view taken on the line 3 3 of Fig. 2;

Fig. 4 is a sectional view corresponding to Fig. 2 but with the carton tilted into position to measure a quantity of its contents;

Fig. 5 is a similar view of the carton in position to discharge the measured quantity; and

Fig. 6 is a reduced plan view of the blank from which the carton is formed.

The carton illustrated -in the drawing may be formed from a blank (Fig. 6) and as customary is provided with front and rear walls 2 and 4, side walls 6 and 7, and top and bottom walls. The top and bottom walls are formed by llaps 8 on the ends of the front and rear walls, and llaps 10 on the ends of the side walls. Upon folding the blank, the llaps 8 on the rear wall 4 are folded over the corresponding aps on the front wall 2. The end aps 10 on the side walls 6 and 7 are folded beneath the ilaps 8, the aps 8 and 10 being pasted together. Also, the outer edge of the side wall 6 may be pro-vided with a narrow ange or ilap 12 which is pasted to the inner side of the outer margin of the front wall 2. The ends of the laps 8 of the front wall 2 may be provided with narrow tabs 14 folded and pasted over :the ends of the side walls.

In accordance with the present invention, the ap 10 on the upper end of the side wall 6 instead of being pasted throughout its area to the underside of the aps 8, it is folded on transverse lines 16 and 18, and the ap is provided with a rectangular opening 20 having one of its longitudinal walls parallel and adjacent 'to the fold line 16.

The side wall 6 is further provided with an opening 22 which extends substantially the width of the side wall. This opening is provided by cutting a tab 24 in the side wall having a depending nger-piece 26. Upon lifting this tab 24 upwardly by means of the linger-piece from the outside of the carton, the slot 22 may be opened, and when the tab is brought down the opening is closed.

Before completely folding and pasting the blank to form the carton, the llap 10 on lthe upper end of the 2,771,227 Patented Nov. 20,1 1956 side wall 6 is folded on the lines 16 and 18 so as to form a horizontal portion 28 and a downwardly and outwardly inclined portion 30 and a ilange 32. This ilange 32 is adhesively secured to the inner side of the side wall 6, and the horizontal portion 28 is adhesively secured to the overlying tlaps 8. The spacing of the fold lines is such that the fold line 16 and lower edge of the Opening 2 0 is positioned substantially flush with the lower edge of the opening 22, and the inclined portion is arranged at an angle of substantially 45 degrees.

During shipment and when the carton is not in use, the tab 24 may be swung down to close opening 22. As this tab is cut out of the material of the side wall and hence is a close t in the opening, and as the finger-piece 26 extends over the securing ilange 32, the tab 24 is eiectively held closed.

To dispense measured quantities of the contents of the carton, the dispensing opening 22 is opened and the carton is tilted sidewise until the llap portion 30 reaches a substantially horizontal position. As it approaches this position the contents of the carton are free to flow by gravity through the opening 20 and into the measuring pocket formed by the inclined portion or baille 30, the portion 28 and the side Wall 6. When the contents of the carton has lled the measuring pocket suiliciently to fill and thus close the opening 20, the llow of the material into the pocket is necessarily stopped, this occurring substantially as the baille 30 reaches or slightly passes its horizontal position during the tilting of the carton. When this occurs, the user then tilts the carton in the opposite direction until the material ilows from the measuring pocket down through the dispensing opening 22, this occurring when the carton has been returned a sulllcient distance toward upright position to permit the contents in the measuring pocket to llow by gravity out through the dispensing opening.

With cartons of the character described that have heretofore been in general commercial use, the dispensing of the contents has been through an opening in the upper end of one side Wall of the carton, and it has been dilllcult to regulate the quantity of material thus dispensed to the desired quantity, with the result that a quantity greater than what was desired might be dispensed.

It will be apparent that with my improved carton an accurately measured quantity may be dispensed at all times.

When the carton has thus been used, the dispensing opening 22 may be tightly Iclosed by means of the ap 24.

It will also be apparent that my improved carton may be easily formed from the same size blank as cartons having no measuring pockets, and that the measuring pocket does not add materially to the cost of the carton.

What I claim is:

1. A container of the class described having front and rear walls, side walls, and top and bottom walls, said top and bottom walls being formed of overlying ilaps on the ends of the front, rear and side walls, the llap on the upper end of one of the side Walls being bent on a line spaced a distance from its inner end to form a downwardly inclined baille having its upper end spaced from the side Wall and its lower end secured to said side wall, said baille, the opposite portion of said side wall and the inner portion of said tlap forming a measuring pocket, the upper end portion of said baille having a slot through which the contents of the container may flow by gravity into said pocket when the container is tilted downwardly to a suitable position, and the portion of the side wall opposite the lower end portion of said baille being provided with a slot so as to permit the contents 'of the pocket to flow from the container when the container isy tilted in the opposite direction to a suitable position.

mentioned ap has the portion thereof between its inner v end and the upper end of the bafe adhesively secured to the underside of the flaps of the front and rear walls that form the top wall ofthe carton, and has 'its outer end portion, adjacent the lower end of the baie, adhesively secured to the side wall.

3. A structure according to claim 2 in which said slot Ain said side Wall extends substantially the width of Asaid Wall, and i's formed by a ap cut in the side Wall adapted to be bent upwardly to open the slot and bent downward- 1y to close the slot, said ap having a linger `tab at its low-er end adapted `when the flap is closed to engagesaid lower end `portion of the baffleiap 4. A structure according to claim 1 in which the slot in the bale extends centrally and is of a length substantially 5 one-third the width of the baffle, and its width is substantially one-third its iength.
