Sept 15, 1970 H. e. ZASTROW DISPENSING CONTAINER Filed June 16, 1969 INVENTOR /7 4/? L0 G. ZAsTRow arm- ATTORNEY United States Patent 3,528,597 DISPENSING CONTAINER Harold G. Zastr0w, Minneapolis, Minn., assignor to Hoerner Waldorf Corporation, St. Paul, Minn., a corporation of Delaware Filed June 16, 1969, Ser. No. 833,356 Int. Cl. B65d /72 US. Cl. 229-17 9 Claims ABSTRACT OF THE DISCLOSURE A dispenser container includes a rectangular body, including a top panel, first side Wall panel, bottom panel and second side wall panel connected in tubular relation. Rear closure flaps are provided to provide a rear closure. A top panel closure flap and side wall closure flaps form a partial front closure. The closure flap hinged to the front of the bottom wall is provided with side wings cut from the lower portions of the front side wall closure flaps to fold inwardly of the side wall panels and form, with the bottom wall closure flap, a hinged dispensing trough.
This invention relates to an improvement in dispensing container and deals particularly in a shipping container which may be used to ship a product and which may be opened up to permit the dispensing of the container contents.
Many of these include a wall panel provided for hinging the wall portion outwardly, the flaps or wings limiting the extent to which the wall portion may be hinged so as to form a dispensing trough. Such containers are useful in the packaging of bulk parts of one type or another, and similar containers have been used as feeders for poultry or for the like. The present invention resides in a device of the same general type. A feature of the present invention resides in the provision of a dispensing container in which the opening into the container through which the goods are dispensed, as well as the trough portion of the device, are formed entirely in the closure flaps of the container. As a result, the container may generally be of conventional form including four rectangularly arranged walls connected in tubular relation at a manufacturers joint. The only unusual feature lies in a modification of three of the closure flaps which are shaped to provide both the dispenser opening and the dispenser trough.
A feature of the present invention resides in the provision of a dispensing container of the type described in which the pivoted wall forming the main panel of the trough comprises one of the short flaps which usually lie inwardly of the remaining closure flaps, and in which the wings which form the ends of the trough are cut from portions of the adjoining overlying flaps. The wings forming the end of the trough are cut in such a manner that marginal portions of the outermost closure flaps overlie marginal portions of the inner closure flap which forms the dispenser trough so as to hold the contents properly enclosed during shipment and storage.
A further feature of the present invention resides in the provision of a dispenser container of the type described in which generally triangular portions are provided on the outermost closure flaps which overlie the ends of the inner flap which forms the main panel of the trough. These generally triangular portions are detachable so that by removing these areas, the trough may be opened in a conventional manner.
A further feature of the present invention resides in the provision of a dispensing trough which may be reclosed if desired. Tab means are provided for engaging the main wall of the trough to hold the trough in a closed position if and when desired.
These and other objects and novel features of the present invention will be more clearly and fully set forth in the following specification and claims.
In the drawings forming a part of the specification:
FIG. 1 is a perspective view of the container in closed position, or in position for storage and shipment.
FIG. 2 is a perspective view of the trough portion of the container after it has been opened.
FIG. 3 is a sectional view through the trough portion of the container and an adjoining portion of the bottom panel thereof, the position of the section being indicated by the line 33 of FIG. 1.
FIG. 4 is a sectional view similar to FIG. 3, but showing the trough in its open position.
FIG. 5 is a diagrammatic view of the blank from which the dispensing container is formed.
In view of the fact that the panels of the container are normally arranged so that the dispenser trough will be at the bottom of the container, the panels will be described in this manner. As indicated in FIG. 5 of the drawings, the container A includes a top panel 10, a side wall panel 11, a bottom panel 12, and a second side wall panel 13 which are hingedly connected together along parallel fold lines 14, 15, and 16. A glue flap or stitch flap may be provided on an end panel of the series and secured to the other end panel of the series in order to connect the walls in tubular relation. In the particular arrangement illustrated, the panels are held in tubular relation by a strip of tape 17.
Closure flaps 19, 20, and 22 are hingedly connected to the panels 10, 11, 12, and 13 respectively along a common line of fold 23. Closure flaps 24, 25, 26, and 27 are hingedly connected to the panels 10, 11, 12, and 13 along a common line of fold 29. Slots 30, 31, and 32 separate the closure flaps 19, 20, 21, and 22. A slot 33 separates the flap 24 from the flap 25.
Perforated lines 36 and 37 extend across the closure flaps 25 and 27 in equally spaced relation to the fold lines 34 and 35 which are aligned with the fold lines 15 and 16 respectively. A cut line 39 extends diagonally from the juncture between the fold lines 34 and 29 to the fold line 36. This provides a triangular section 40 which is defined by a perforated line 41 extending along the fold line 29, the perforated line 36, and the diagonal cut line 39. Outwardly of the triangular removable section 40 is provided a generally trapezoidal wing 42 having an outwardly extending projection 43 on its extremity. The wing 42 forms one side of the dispensing trough.
A diagonal cut line 44 extends from the intersection of the fold lines 35 and 29 to the perforated line 37. This provides a triangular detachable section which is defined by the perforated line 37, a perforated line 46 extending along the fold line 29, and the out line 44. As will be later described, the triangular portion 45 may be removed when the dispensing trough is to be used.
The diagonal cut line 44 also provides a trapezoidal Wing 47 similar to the wing 42 hinged to the closure flap 26 along the fold line 35, and which is provided with an outwardly extending projection 49 at its extremity. The cut lines separating the ends of the wings 42 and 47 from the remainder of the closure flaps 25 and 27 are shaped to provide short downwardly extending projections 50 and 51 which assist in the reclosing of the dispensing trough.
In closing the container, the closure flaps 19 and 21 are folded into a common plane, and the closure flaps 20 and 22 are folded into face contact with the outer surfaces of the inner flaps 19 and 21 to fold into edge abutting relation. A strip of tape 52 is applied over the joint. Preferably the ends of the tape strip 52 extend over the top and bottom panels 10 and 12 as indicated in FIG. 1.
After the container has been filled, the opposite wall of the container is closed. This is accomplished by folding the wings 42 and 47 along the fold lines 34 and 35 into right angular relation with the closure flap 26, and folding these wings inwardly of the vertical wall panels 11 and 13, folding the closure flap 26 and the opposite closure flap 24 into a common plane. The closure flaps 25 and 27 are folded to lie outwardly of the flaps 24 and 26, and a strip of tape 53 is applied to the abutting edges of the closure flaps 25 and 27, as indicated in FIG. 1 of the drawings. The lower portion of the dispensing container then appears as indicated in FIG. 3 of the drawings. The container is shipped in this condition. It will be noted that the triangular areas 40 and 45 overlie the ends of the flap 26 to prevent leakage of the contents.
When the contents are to be dispensed, the tape 53 is slit in substantial alignment with the perforated lines 36 and 37, and the triangular areas 40 anl 45 are grasped and torn out. The trough may then be opened up into the position shown in FIGS. 2 and 4 of the drawings, the projections 43 and 49 engaging against the inner surface of the panels 25 and 27 to limit the extent to which the trough is opened. If it is desired to reclose the dispenser opening, the flap 26 may be swung back, and the upper edge of this flap may be flexed past the projections 50 and 51 to reclose the trough.
