10 Claims.

This invention relates to certain new and useful improvements in paper or cardboard cartons for the packaging and convenient dispensing of freely flowing materials, such as talcum powder, tooth powder, and the like.

It has for one of its objects to provide a carton of this character which is made of a single blank of material and embodies as an integral part thereof a self-contained dispensing head including a fracturable portion which normally seals the contents of the carton and which can be readily broken when it is desired to dispense the contents therefrom.

Another object of the invention is to provide a dispensing carton which is simple and inexpensive in construction, which can be readily folded or set up for use, and wherein the dispensing head of the carton is provided with a fracturable selfcontained, captive closure member designed to effectually seal the container-contents until the purchaser desires to make use thereof, when he can readily fracture or separate the closure from its anchored position and thereafter shift it at will to an open or closed position, as desired.

Other features of the invention reside in the construction and arrangement of parts hereinafter described and particularly pointed out in the appended claims.

In the accompanying drawing:

Figure 1 is a perspective view of the dispensing carton embodying our invention. Figure 2 is a top plan view thereof, partly in section, showing the fracturable sealing or closure member in its closed position. Figure 3 is a similar view but showing the closure member in its open position for dispensing purposes. Figure 4 is a fragmentary perspective view of the dispensing end of the carton showing the self-contained closure construction on one of the end walls or flaps in its final assembled position. Figure 5 is a similar view showing the closure construction in its partially folded condition prior to final assembly.

Figure 6 is an enlarged cross section taken on line B--6, Figure 1. Figure '7 is a plan view of the blank from which the carton is made.

Similar characters of reference indicate corresponding parts throughout the several views.

This dispensing carton is made of cardboard or like material, that shown in the drawing, by way of example, being rectangular in shape and formed from a single blank to of cardboard by cutting and scoring the same as indicated at II and I2, respectively, to provide side walls [3, lower closure flaps or end walls i4, and upper closure flaps or end walls l5, I6, I1 and I8, whereby the several walls may be folded or bent in an obvious manner and glued to form the completed carton. At one of its side edges the blank is provided with a longitudinal sealing strip IQ for connecting the side walls into a box-like unit.

The upper group of overlapping closure flaps form the dispensing end of the carton and one of the flaps is provided with an integral and selfcontained, fracturable closure construction which normally closes or seals the carton-contents against discharge and which can be readily opened or unsealed when it is desired to dispense the contents. The foldable end walls l5-ll, inclusive, are each provided with a discharge port or perforation 20 so located that in the folded condition of the carton these perforations register with each other. The end flap l8, which is located outermost in the folded condition of the carton, has dispensing ports 2| therein in register with the companion ports 20 and constitutes the discharge or dispensing controlling element of the carton and for this purpose is preferably provided with an extension 22 including a plurality of interfolding sections 23, 24 and 25. The intermediate section 23, adjoining the flap I8, is substantially of the same dimensions as such flap and is connected thereto by a fold line 26, while the companion sections 2 1, 25 are joined as a unit to the section 23 by a fold line 21 parallel to the fold line 26. The section 24 is comparatively narrow and serves as a marginal sealing strip for the section 25 for securing it to the contiguous faces of the section 23 and flap ill in the assegmbled, overlying folded condition of such parts, as shown in Figures 4, 5 and 6. The companion section 25, which serves as a fracturable end captive sealing-closure for the flap-perforations 20 and 2i, is connected to the adjoining end of the sealing-flap section 24 by a fracturable fold line 28 disposed parallel to the fold 21. The extensionsections are folded in overlying relation against the underside of the flap l8 with the sealable section 24 and the fracturable section 25 disposed between the latter and the intermediate section 23, as shown in Figures 4, 5 and 6. The discharge port or perforation 2| of the latter is adapted to register with the other perforations 20 in the closed condition of the container, and the fracturable section 25 in the folded assembled condition of these parts, overlies and closes these discharge perforations to seal the contents in the container. At its outer or free end the fracturable section is reduced in width to provide a finger tab 29 which, in the folded condition of the parts, is adapted to extend through a companion opening 30 in that portion of the flap l8 and the section 23 adjacent the fold 26, whereby to expose this tab for manual gripping engagement when it is desired to break the seal and render the carton operative for dispensing its contents. It will be noted that the finger tab, in the closed position of the fracturable section 25, is contained within the area of the carton-body. When it is desired to use the carton after purchase and dispense its contents, the user grasps the finger tab and smartly pulls it outwardly to break the fracturable fold connection 28 between the sealed section 24 and the section 25 to thereby uncover the discharge ports 2i, 2! and the remaining alining registering perforations 20 in the end flaps. The tab-forming portion of the end section 25 forms resulting shoulders 3i at opposite sides thereof and those portions of the fold 2d at opposite sides of the opening 30 in the end flap l8 form companion shoulders 32, which shoulders jointly limit the outward displacement of the fracturable end section and thereby retain it captive between the companion section 23 and the underlying flap is. After the closure section is once broken from its companion sealed section 24, it is free to be moved at will to and from an open position.

We claim as our invention:

1. A container of the character described, comprising a cardboard body having overlapping end closure flaps having registering perforations therein, the outermost flap including a plurality of interfolded sections constituting a dispensing head, one of the sections having dispensing perforation therein in line with the remaining flapperforations and the other section having a fracturable connection to the companion first-named section and normally covering the perforation thereof to seal the container-contents.
