DISPENSING CONTAINER Filed Feb. 5. 1951 Inventor Allomey Patented Aug. 30, 1932 UNITED STATES PATENT OFFICE Application filed February 3, 1931. S'erial 110. 513,203.

This invention relates to improvements in dispensing containers, and more particularly to cardboard boxes embodying means whereby the contents of the box may be sifted out or dispensed when desired, and kept closed at other times to prevent-the contents from accidentally spilling out, and to protect the same against contamination by insects and dampness.

Another object of the invention is to provide a cardboard box with a discharge opening, and closure meansformed in the construction of the box foropening and closing said discharge opening when desired.

A further object is the provision of a folding cardboard boxembod ing the above features of construction-whic does not materially increase the cost of manufacture of the article over the present construction of cardboard boxes.

With these and other objects in view, the invention resides in the certain novel construction, combination and arrangement of parts, the essential features of which are hereinafter fully described, are particularly pointed out in the appended claims, and are illustratcd in the accompanying drawing, in which V Figure 1 is an end elevational view show- 3@ ing the closure member before it is broken from the end wall of the box.

Figure 2 is a similar view with parts broken away showing the closure member broken from the box and in open position. t

In the drawing the box is designated at 28 and includes an outer end wall or flap 29 and an inner wall or flap 30, a portion of the flap or wall 30 is provided with a discharge open-- ing 31 while the outer wall or flap 29 is cut on parallel lines 32, which lines are beyond the confines of the discharge opening 31. The

outer wall or flap 29 is also cut at right angles to the cut 32 as at 33, while perforations 3 1'are provided in the end flaps 29 between the inner ends of the cut 32 and the opposite ends of the cut 33. These lines of perforations extend outwardly beyond the plane of the cut 32 for a purpose to be presentlyexplained. The lines of cut 32terminate adj acent one of the edges of the end wall 29 as at 35. By reference to Figure 1, it will be seen that the cut portions 32 and 33, and the scored or perforated portions 34 and 35 define a closure member '36, which is provided with outwardly extending flanges 37 at its inner end, and which closure member overlies the discharge opening 31.

- In use, these scored or perforated portions 34 and 35 are broken by pushing inwardly upon the closure member 36 which causes the member to separate from the end walls 29. When the closure member 36 is depressed inwardlybeyond the plane of the end wall 29, the same may be pulled outwardly to uncover the discharge opening 31 as shown in Figure 2 of the drawing. When pushed inwardly, the flanges 37 will be disposed in the space between the outer end wall 29 and the inner end wall 30. These walls 29 and 30 are adhesively secured together as at 38 beyond the surfaces disposed in the path of the said flanges, but the adhesive bond or joint between these walls prevents the accidental pulling of the closure member from the box. Besides serving to limit the outward movements of the closure member, the flanges 37 act as guides for assuring a true sliding of the closure member with relation to the end walls of the box. When moving the closure member 36 to a closed position,- the same is pushed inwardly beyond the cut edge 33 on the end wall 29 so as to underlie such edge and prevent accidental separation of the closure member from the box, and if desired, the adhesive between the end wallsmay be omitted adjacent the said out edge as shown in dotted lines in Figure 2.

While I have shown and described what I consider to be the most desirable embodiment of my invention, it will be understood that various changes in construction may be resorted to if desired without in any way departing from the spirit of the invention and I do not limit myself anything less than the whole as covered by the appended claims. 7

Having thus desc ribed the invention, what I claim as new and desire to secure by Letters Patent is i 1. In a cardboard box having a bod protwo p iesof 100 vided with a wall composed o material, the inner ply havin a discharge opening therein, a closure mem r extending inwardly from one edge of said wall and partiall out from the other ply of material and 5 over King said discharge opening to normally seal t e same, said closure member adapted to be punched inwardly to free the same from the ply of material from which it is formed, and to position the closure member below the m plane of said ply-of material, and a pair of outwardly extending wing portion at the inner end of said closure member adapted to slide between the plies of material during movement of said closure member to opened and closed positions when in use.

2. In a cardboard box having a body provided with a wallcomposed of two plies of material, the inner ply having a discharge opening therein, a closure member extending go inwardly from one edge of said wall and partially cut from the other ply of material and overlying said discharge opening to normally seal the same, said closure member adapted to be unched inwardly to free the same from :5 the p y of material from which it is formed, and to position the closure member below the plane of said ply of material, and a pair of outwardly extending wing portion at the inner end of said closure member adapted toslide between the plies of material during movement of said closure member to opened andclosed positions when in use, and means int-he path of sliding movementiof said wing portionsto limit'the outward slidin move- 36 ment of said closure member-after t es'ame has been moved to a position to open said discharge opening.

In testimony whereof I aflix'my signature.
