Apparatus and method for forming hinged top cigarette box
First Claim
1. An apparatus for forming a hinged top cigarette box from a one-piece blank, the one piece blank having first and second edges and located therebetween, cut-out and hinge features, the apparatus comprising:
- a. a frame;
b. a hopper connected to said frame for holding a support of one piece blanks;
c. a mandrel rotatably mounted on said frame for wrapping said one piece blank around itself to form a plural layered shell;
d. a pusher bar and a stop disposed adjacent said mandrel, said pusher bar pushing said one piece blank and said stop engaging said cut-out feature to align said first edge of said one piece blank, so that said cut-out and hinge features register with each other when said one piece blank is wrapped around itself;
e. transferring means adjacent to said hopper for transferring a one piece blank from said hopper to said mandrel; and
f. an ultrasonic sealing device movably mounted on said frame and having an acoustical horn for engagement with said mandrel for sealing said one piece blank after said one piece blank has been wrapped around itself.

Abstract
An apparatus for forming a hinged top cigarette box having a cross-section with one or more arcuate surfaces from a one piece blank, the apparatus comprising a mandrel that engages the one piece blank along an edge, and which mandrel rotates to wrap the blank around the mandrel to form a hinged top cigarette box having inner and outer walls. Alternative embodiments of the apparatus may include either an ultrasonic device or wet adhesives to secure the inner and outer walls of the box in proper relation. A method is provided for forming a dual layer hinged top cigarette box having a cross-section with one or more arcuate surfaces wherein a box blank is engaged along one end and then rotated and secured so that the resulting box has its inner and outer layers fixed in proper relation.

13. A method of forming a hinged top cigarette box having dual layers and an arcuate surface from a one piece blank, the one piece blank having first and second edges and located therebetween, cut-out and hinge features, the method comprising the steps of:
-
engaging said first edge of said one piece blank to a mandrel while aligning said one piece blank by abutting a portion of said one piece blank to a stop located near said mandrel; aligning said cut-out and hinge features by rotating said mandrel to wind said one piece blank around itself to form a dual layered shell having inner and outer sleeves and having an arcuate surface; and securing said second edge of said one piece blank to said outer sleeve of said dual layered shell. - View Dependent Claims (14, 15)

16. A method of forming a hinged top cigarettes box having dual layers and an arcuate surface from a one piece blank, said one piece blank having first and second edges and located therebetween, a first portion serving as an inner sleeve and a second portion serving as an outer sleeve, the method comprising the steps of:
-
engaging said first edge of said one piece blank with a mandrel while aligning said one piece blank by abutting a portion of said one piece blank to a stop located near said mandrel; aligning said second portion of said one piece blank with said first portion of said one piece blank by rotating said mandrel to wind said one piece blank around itself to form a dual layered shell having an arcuate surface so that said first and second portions of said one piece blank define inner and outer sleeves, respectively; and securing said second edge of said one piece blank to said outer sleeve of said dual layered shell. - View Dependent Claims (17, 18)
