Abstract

A carton blank and a method for folding and gluing it into a reclosable carton.

Claims

1. A tamper-evident, top-opening carton comprising:

(A) a receptacle portion having opposite ends and including front, bottom, rear, and top panels hingedly connected to each other in the order stated;

(B) means for closing one end of said carton including

a bottom end flap hingedly connected to the bottom panel;

a rear end flap hingedly connected to the rear panel and adhesively connected to the bottom end flap;

a front end flap hingedly connected to the front panel and adhesively connected to the bottom end flap;

a front cover sealing flap, having (1) a front cover skirt hingedly connected to the top panel, (2) a first adhesive tab adhesively connected to the front panel, (3) a tear strip connecting the front cover skirt to the first adhesive tab, and (4) a corner post flap having (a) a corner hood tab hingedly connected to the front cover skirt, (b) a second adhesive tab adhesively connected to the front end flap, and (c) a first severance line connecting the corner hood tab to the second adhesive tab for severing the corner hood tab from the second adhesive tab when a user initially opens the carton;

a top end flap, hingedly connected to the top panel, having an end cover skirt adhesively connected to the corner hood tab, a third adhesive tab adhesively connected to the rear end flap, and a second severance line connecting the end cover skirt to the third adhesive tab for severing the end cover skirt from the third adhesive tab when a user initially opens the carton;

wherein the top panel, the end cover skirt, the front cover skirt, and the corner hood tab form a reclosable cover for the carton, when a user removes the tear strip and severs the end cover skirt from the third adhesive tab and severs the corner hood tab from the second adhesive tab; and

(C) means for closing the other end of the carton.

2. The carton of claim 1 wherein the means for closing the other end of the carton is substantially identical to the means for closing the one end of the carton.

3. An integral carton blank for forming a reclosable top-opening carton comprising:

(A) front, bottom, rear, and top panels, hingedly connected to each other in the order stated, for forming a receptacle portion having opposite ends;

(B) means for closing one end of said receptacle portion including

a bottom end flap hingedly connected to the bottom panel;

a rear end flap hingedly connected to the rear panel and adapted to be adhesively connected to the bottom end flap;

a front end flap hingedly connected to the front panel and adapted to be adhesively connected to the bottom end flap;

a first cover sealing flap, having (1) a front cover skirt hingedly connected to the top panel, (2) a first adhesive tab adapted to be adhesively connected to the front panel, (3) a tear strip connecting the front cover skirt to the first adhesive tab, (4) a corner post flap having (a) a corner hood tab hingedly connected to the front cover skirt, (b) a second adhesive tab adapted to be adhesively connected to the front end flap, and (c) a first severance line connecting the corner hood tab to the second adhesive tab for severing the corner hood tab from the second adhesive tab;

a top end flap, hingedly connected to the top panel, having an end cover skirt adapted to be adhesively connected to the corner hood tab, a third adhesive tab adapted to be adhesively connected to the rear end flap, and a second severance line connecting the end cover skirt to the third adhesvie tab for severing the end cover skirt from the third adhesive tab;

wherein the top panel, the end cover skirt, the front cover skirt, and the corner hood tab are adapted to form a reclosable cover for the carton; and

(C) means for closing the other end of the receptacle portion.

4. A method of closing an end of a carton tube erected from a carton blank having

(A) a receptacle portion having opposite ends and including front, bottom, rear, and top panels hingedly connected to each other in the order stated;

(B) means for closing one end of said receptacle including

a bottom end flap hingedly connected to the bottom panel;

a rear end flap hingedly connected to the rear panel and adapted to be adhesively connected to the bottom end flap;

a front end flap hingedly connected to the front panel and adapted to be adhesively connected to the bottom end flap;

a front cover sealing flap, having (1) a front cover skirt hingedly connected to the top panel, (2) a first adhesive tab adhesively connected to the front panel, (3) a tear strip connecting the front cover skirt to the first adhesive tab, and (4) a corner post flap having (a) a corner hood tab hingedly connected to the front cover skirt, (b) a second adhesive tab adhesively connected to the front end flap, (c) a first severance line connecting the corner hood tab to the second adhesive tab for severing the corner hood tab from the second adhesive tab when a user initially opens the carton; and

a top end flap, hingedly connected to the top panel, having an end cover skirt adapted to be adhesively connected to the corner hood tab, a third adhesive tab adapted to be adhesively connected to the rear end flap, and a second severance line connecting the end cover skirt to the third adhesive tab for severing the end cover skirt from the third adhesive tab when a user initially open the carton;

wherein the top panel, the end cover skirt, the front cover skirt, and the corner hood tab are adapted to form a reclosable cover for the carton;

said method comprising the steps of;

folding in the bottom end flap and folding out the top end flap;

applying adhesive to the bottom end flap and the top end flap;

folding in the front end flap into contact with the bottom end flap adhesive for adhering the front end flap to the bottom end flap, the corner post flap also being folded to form part of the end of the receptacle because of the adhesive attachment of the second adhesive tab to the front end flap;

folding in the rear end flap into contact with the bottom end flap adhesive for adhering the rear end flap to the bottom end flap; and

folding in the top end flap for adhering the top end flap to the corner post flap and to the rear end flap.

5. The method of claim 4, wherein the carton blank further includes means for closing the other end of the receptacle,

further comprising the step of closing the other end of the receptacle.

6. The method of claim 4, wherein the carton blank further includes means for closing the other end of the receptacle, and further comprising the steps of filling the carton tube with desired product;
