MEASURING DISPENSER FOR GRANULAR SUBSTANCES Filed July 25, 1958 a 2 Sheets-Sheet 2 INVENTOR. azm/ z. FMMAA/ JrraAM/E) United States Patent DISPENSER FOR 'GRANULAR SUBSTANCES MEASURING This invention relates to a measuring dispenser for dry granular substances and more particularly to a measuring dispenser in conjunction with a closed carton containing granular substances.

Heretofore without the use of a measuring cup or other device it is some times difiiicult for the user to estimate exactly how much granular substances has been poured from the carton as for example detergents, soap chips, etc. v A

It is the object of the present invention to provide in a carton enclosing a granular substance, a measuring chamber at one end thereof and associated with an outlet spout whereby said spout will deliver upon tipping of the carton only the contents of the measuring chamber.

It is another object of the invention herein to provide upon the interior of the carton a partition spaced above the bottom wall defining therebetween a measure chamber of predetermined volume, together with a series of angularly inclined inlet defining tabs opening into said chamber whereby with the carton in upright position, the chamber will automatically fill and further wherein upon tipping of the carton for pouring and emptying of the measuring chamber through the spout communication between the measuring chamber and the interior of the carton is cut ofi.

These and other objects will be seen from the following specification and claims in conjunction with the appended drawing in which:

Fig. 1 is a perspective schematic view of a carton illustrating the measuring dispenser therefor.

'.:Fig..'2 is a layout pattern .scored' and slit adapted for forming into the present carton and. measuring device.

Fig. 3 is a diagrammatic fragmentary end view of the assembled carton illustrating the construction of the measuring chamber.

Fig. 4 is a schematic fragmentary perspective view of the folded portion of the carton blank as scored and slit before formation of the inlet defining tabs to the measuring chamber.

Fig. 5 is a similar view illustrating the tabs as formed and folded into series of inlets.

It will be understood that the above drawing illustrates merely preferred embodiment of the invention and that other embodiments are contemplated within the scope of the claims hereafter set forth.

Referred to the drawing, the assembled carton of Fig. 1 is formed from the flat pattern blank, Fig. 2, which has been slit and scored in a conventional manner and which upon proper folding defines the side, end, top and bottom walls of the carton shown in Fig. 1.

The blank includes side wall 11, end wall 12, side wall 13 and end wall 14 with the additional securing flap 15 for completing the carton structure in a conventional and well-known manner.

Adjacent side wall 11 and defined by suitable scoring is bottom Wall 16 with assembly tab 17 at one end, and beyond the horizontal score or fold line 19 is the extension generally indicated at-18 and from which the measure chamberand inlet tabs therefor are formed. Referring to Fig. 3, upon initial assembly of the walls 11, 12, 13 and 14, the extension 18 is first folded along the line 19 so that the member 22 defines a side wall extension engageable with the interior of wall 13.

This extension terminates in the partition 24 which extends between walls 11-13 and is spaced above bottom wall 16 so as to define therewith the measure chamber 37 of predetermined volume.

Partition 24 as indicated in Figs. 1 and 3 terminates in the depending wall element 23 which bears against and is suitably secured to the interior of wall 11. The assembly is further completed by folding of bottomwall 25 against the undersurface of bottom wall 16 and securing thereto in a conventional manner.

The blank shown in Fig. 2 is slit along solid line portions which extend into the interior of the blank.

Referring to Figs. 2, 4 and 5, extension 18 has formed theretli'rough a series of parallel slits 26 which extend across the top of partition 24 and into portions of side wall elements 22-23 which are adapted to be folded along the score or fold lines 9.

Slits 26 at their opposite ends terminate in the notches 27, and the latter terminate in the forwardly extending slits 28. The latter slits terminate in the rearwardly extending slits 29 and the outwardly extending slits 30 which end respectively at Opposite sides of partition 24 adjacent the series of parallel spaced fold lines 31,

This series of slits within extension 18, upon folding of said extension as indicated in Figs. 4 and 5 and upon proper folding of portions defined by said slits define a series of inverted U-shaped tabs 32 whose downwardly depending ends 33 terminate in forward extensions 34 adapted to underlie and retainingly engage partition 24 when the individual tabs 32 have been folded to the position shown in Fig. 5.

At that position the respective notches 27 effectively interlock with free edge portions of partition 24 for fixedly securing the respective angular tabs 32 in the position shown in Figs. 1 and 5.

' The upwardly extending tab top walls 32 while integral with partition 24 are pivotally hinged thereto at 31 and extend upwardly at an acute angle.

The-forward ends of said tabs in cooperation'wi g1 members 33, and of course, the side walls 11 and 13 define a series of'substantially upright elongated .rectane 'gular inlets 35 in communication with measure chamber 37. By this construction the measure chamber 37 will be filled by the gravitational movement of granular substances from the interior of the carton.

As shown in Fig. 5, the formation of the inverted U- shaped inlet defining tabs 3233 leaves within side wall elements 2223 the apertures 36 which, however, are suitably closed by the adjacent carton walls 11-13.

Bottom wall 16 has at one end a conventional tab 38 centrally apertured at 39 defining part of the outlet for measuring chamber 37. Upon assembly of the carton slit tab 40 underlies bottom wall 16, and the end wall 12 registers with upright tab 38. Wall 12 is slit along the line 41 and defines with fold line 42, the hinged tab 43 which provides a closure for the other part to the outlet for the measure chamber in registry with aper ture 39.

A suitable wedge-shaped dispenser spout 44, shown in Fig. 1, is mounted upon the lower end of wall 12, with its wedge shaped sides 45 projecting through the opening in wall 12 defined by the slit 41 and through the aperture 39.

The upright enlargements 46 at opposite ends to the spout retainingly engage interior surface portions of tab 38 and wall 12 for outward limiting swinging movement Patented Oct. 27, 1959 v to the position shown in Fig. 1. The hinged tab 43 is suitably secured to the interior surface of spout 44 and swings open with respect to the apertures 39 and 41 upon manual opening movement of spout 44.

The blank shown in Fig. 2 .is additionally cut scored and slit so as to define a conventional top wall construction which includes top wall 47 with sealing end tabs 50, the end wall tabs 48, and the additional top wall 49 to complete the closure of the present carton. Said carton is normally filled with dry granular substances, such as soap chips, detergents, cleaning powders, or any like granular substances such as rice, barley, sugar, etc.

Initially the interior of the carton as Well as the measuring chamber is filled with the dry granular substance. In view of the fact that the carton is in upright position the granular substances will gravitate through the inlets 35 into the measuring chamber 37 until such chamber is filled. In use with spout 44 open, as shown in Fig; 1, the carton is tilted in a conventional manner up to 90 degrees for emptying measuring chamber 37.

It will be noted that the inlets 35 which are substantially' upright in Fig. 1 will have been rotated into a substantially horizontal position. Accordingly closing off the measuring chamber 37 from the remaining contents of the carton. This means that upon said tilting action, there will be dispensed from the carton only the predeterm'med measured content from chamber 37. Just as soon, however, as the carton is returned to its normal upright position, additional substances will again gravitate filling chamber 37 through inlets 35.

Having described my invention, reference should now be had to the following claims.

I claim:
