Abstract

An improved reclosure carton and blank are provided. The blank uses a minimum of paperboard material in achieving a properly supported top that can easily and repeatedly be opened and closed. The ease of opening the carton is facilitated by pairs of alignment embossments and debossments on portions of adjacent inner and outer first side panels. The top of the carton is supported in its closed condition by top support panel which includes an aperture through which the material stored in the carton can be dispensed. The slide panel then is foldably disposed over the top support panel so as to selectively enable complete closure of the aperture therein. Inner and outer top closure panels then securely close the carton.

Claims

1. A slide top recloseable dispenser carton comprising:

opposed rectangular front and rear walls disposed in spaced parallel relationship;

first and second opposed side walls disposed in spaced parallel relationship and extending between and connecting said front and rear walls, said first side wall including inner and outer panels disposed in face-to-face contacting relationship, said outer panel of said first side wall including a base portion adhered to the inner panel thereof and a hinged portion rotatable about said base portion thereof toward and away from the inner panel;

a bottom wall connected to and extending between the base portion of said first side wall, said second side wall and said front and rear walls; and

a top wall comprising a top support panel articulated to said second side wall and defining the innermost portion of said top wall, said top support panel including an aperture extending therethrough, a slide panel articulated to the hinged portion of the outer panel of said first side wall, said slide panel being disposed in face-to-face contact with said top support panel and covering the aperture therein, and inner and outer top closure panels articulated respectively to said rear and front panels and being folded over said slide panel, said inner top closure panel including an aperture substantially identical to the aperture in said top support panel and disposed in register therewith, said outer top closure panel including an array of perforations defining a removable closure flap in register with the apertures in said inner top closure panel and said top support panel, whereby rotation of said hinged portion of said first side wall enables movement of the slide panel relative to the apertures in the top wall, said top support panel extending substantially the entire distance between said front and rear panels of said carton, whereby said front and rear panels frictionally support said top support panel in a plane generally orthogonal to the first and second side walls of the carton.

2. A carton as in claim 1 wherein the hinged portion of said outer panel or said first side wall includes an outwardly extending embossment, and wherein the inner panel of said first side wall includes an inwardly extending debossment in register with the embossment of the outer panel, whereby said registered embossment and debossment substantially prevent the hinged portion of said outer panel from being adhered to the inner panel of said first side wall.

3. A carton as in claim 2 wherein said base portion of said outer panel is adhered to the inner panel of said first side wall, and wherein the debossment and embossment are substantially in line with the adhesive between said inner and outer panels of said first side wall.

4. A carton as in claim 1 wherein said inner and outer top closure panels include generally registered cutouts at the edges thereof adjacent said first side wall of said carton, said cutouts being dimensioned to facilitate movement of the slide panel relative to said inner and outer top closure panels.

5. A carton as in claim 3 wherein the embossment and debossment define a width between said front and rear panels of said carton greater than the width of the adhesive disposed intermediate the inner and outer panels of said first side wall.

6. A blank for forming a recloseable slide top dispenser carton, said blank comprising:

rectangular outer first side panel, rectangular rear panel, rectangular second side panel, rectangular front panel and rectangular inner first side panel consecutively articulated to one another along parallel fold lines, said outer first side panel, said second side panel and said inner first side panel being of substantially identical size and shape, said front and rear panels being substantially identical, said outer first side panel including a base portion articulated to said rear panel and a hinged portion articulated to said base portion along a fold line extending generally perpendicular to the articulation between said outer first side panel and said rear panel, said hinged portion being separated from said rear panel by a cut line extending collinearly from the articulation between said outer first side panel and said rear panel;

bottom panels articulated respectively to each of said outer first side panel, rear panel, second side panel and front panel;

a top support panel articulated to said second side panel along a fold line extending perpendicular to the articulation between said second side panel and said front and rear panels, said top support panel including an aperture extending therethrough and having a width substantially precisely the same as the width of the second side panel, whereby in the erected carton said front and rear panels can frictionally support said top support panel in a plane generally orthogonal to the first and second side walls of the carton;

a slide panel articulated to the hinge portion of said outer first side panel along a fold line extending perpendicular to the cut line between said hinged portion and said rear panel; and

inner and outer closure panels articulated respectively to said rear and front panels along fold lines extending collinearly from the articulation between said top support panel and said second side panel, said inner closure panel including an aperture substantially identical to the aperture in said top support panel, said outer top closure panel including an array of perforations defining a removeable seal substantially identical in shape to the aperture in said top support panel and in register therewith.

7. A blank as in claim 6 wherein said outer closure panel further includes a cutout adjaent said array of perforations therein, said cutout being dimensioned to facilitate grasping of the removeable seal defined by said array of perforations.

8. A blank as in claim 6 wherein said inner and outer closure panels include cutouts defining edges thereof most distant from said top support panel, said cutouts being dimensioned to facilitate grasping of the slide panel on the carton erected from the blank.

9. A blank as in claim 6 wherein said hinged portion of said outer first side panel includes an embossment extending into said blank so as to be outwardly extending on the carton erected from the blank, and wherein said inner first side panel includes a debossment extending into said blank in a direction so as to be inwardly extending on the carton erected from said blank, said embossment and debossment being substantially identical in shape and being disposed to lie in register with one another on the carton erected from the blank.

10. A blank as in claim 9 wherein the base portion of the outer first side panel includes a strip of adhesive extending generally parallel to the articulation between said outer first side panel and said rear panel and being generally in line with the embossment in the hinged portion thereof.

11. A blank as in claim 6 further comprising a rear flap articulated to said inner first side panel along a fold line extending generally parallel to the fold line between said inner first side panel and said front panel.
