Abstract
Abstract A container which has a plastic cutting strip is described wherein the edge of the cutting strip is preferably serrated and the strip is adhered to the container throughout the length of the strip. An apparatus is also described for applying the strip to containers using a continuous length of strip wherein serrating means are mounted on the apparatus for serrating an edge of the strip and cutting and applying means for applying the strip to the container blank is mounted over a conveyor table downstream of a hot melt extruder providing hot melt adhesive on the container blank.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
142 words
AN APPARATUS FOR APPLYING A FLEXIBLE CUTTING STRIP TO A CONTAINER FROM A CONTINUOUS ROLL WHICH INCLUDES MEANS FOR FEEDING A CONTINUOUS STRIP OF A MATERIAL, CONVEYING MEANS FOR PASSING A PLURALITY OF CONTAINERS IN LINE ONE BY ONE, THROUGH AN APPLICATION STATION, AN ADHESIVE EXTRUDER LOCATED ADJACENT THE CONVEYING MEANS FOR APPLYING ADHESIVE TO ONE OF THE CONTINUOUS STRIP AND A CORRESPONDING AREA ON THE CONTAINER, MEANS FOR CUTTING A PREDETERMINED LENGHTH OF THE CONTINUOUS STRIP TO BE APPLIED TO THE CONTAINER, MEANS FOR APPLYING THE CUT PREDETERMINED LENGTH OF STRIP TO THE CONTAINER WITH THE ADHESIVE AT THE APPLICATION STATION, MEANS FOR FORMING A SERRATED EDGE CONTINUOUSLY ALONG ONE EDGE OF THE STRIP PROVIDED UPSTREAM OF SAID CUTTING MEANS, MEANS COORDINATING THE APPLICATION OF ADHESIVE AND MEANS FOR COORDINATING THE APPLICATION OF THE PREDETERMINED LENGTHS OF STRIP TO EACH CONTAINER.

Claim 3
Dependent Claim
53 words
An apparatus as defined in claim 1 wherein the containers are fed in a flat blank form on a conveying means and the means for applying the adhesive includes an adhesive extruder located adjacent the conveying means and adapted to provide an elongated area of adhesive on a predetermined area on the blank.
Claim 4
Dependent Claim
23 words
An apparatus as defined in claim 2 wherein the extruder is operative with hot melt adhesive and is located above the conveying means.
Claim 5
Dependent Claim
120 words
An apparatus as defined in claim 1 wherein the means for forming a cutting edge on the continuous strip includes a shearing plate with a shaped recess on one edge thereof, press rolls engaging opposite sides of the strip for advancing it through the cutting means, a housing mounting the shear plate and the press rolls, a driven shaft mounted in the housing and fly cutting arms on the shaft including cutting tips on the ends of the arms conforming to the shape of the recess in the shear plate, and adapteD to pass in close proximity to the edges of the shear plate forming the recess, thereby serrating the strip as it is being advanced by the press rolls.
Claim 6
Dependent Claim
107 words
An apparatus as defined in claim 1 wherein the application station includes a first movable surface mounted above the conveyor means and a second movable surface mounted on a bracket movable to and from the first movable surface, drive means for driving one of said movable surfaces and means for pressing the second movable surface against the first movable surface for engaging the strip and feeding it onto a container and a cutting blade arranged on the bracket mounting the second movable surface such that it will sever the strip when a predetermined length of the strip has been moved by the first and second movable means.
Claim 7
Dependent Claim
82 words
An apparatus as defined in claim 5 wherein the application station includes a first frame member, a pair of driven rollers mounted on the frame member, a strip feeding path being defined tangent to the peripheries of said rollers, a second frame member movable relative to the first frame member mounting a pair of rollers such that when the frames are in close proximity the rollers on the movable frame will engage the rollers on the fixed frame for feeding the strip.
Claim 8
Dependent Claim
61 words
An apparatus as defined in claim 6 wherein the cutting blade includes a blade defining an aperture in the blade having a cutting edge, said blade being mounted on the moving frame and adapted to move with the movable frame in shearing cooperation with a shearing block on the fixed frame for cutting the strip as the movable frame is retracted.
Claim 9
Dependent Claim
69 words
An apparatus as defined in claim 1 wherein the means for coordinating the application of adhesive includes sensing means for sensing the leading edge of a container blank as it is being advanced on the conveyor means, signal means for operating an adhesive extruder located adjacent the conveying means in response to the sensing means, means for measuring the amount of time that the extruder is to be operated.
Claim 10
Dependent Claim
115 words
An apparatus as defined in claim 6 wherein the means for coordinating the application of the strip to the container includes the piston and cylinder arrangement for positively moving the movable frame from a disengaged retracted position to a position in close proximity with the fixed frame, sensing means for sensing the leading edge of a container blank as it is being advanced on the conveyor means, signal means responsive to the sensing means for actuating the piston and cylinder arrangement to move the movable frame into close proximity with the fixed frame and means for measuring the amount of time that the movable frame is to be in close proximity with the fixed frame.
Claim 11
Dependent Claim
102 words
An apparatus as defined in claim 8 wherein the means for measuring the amount of time includes an electronically-operated clutch responsive to a signal from said sensing means, a disc driven through said clutch, a strip of light-colored material mounted on the periphery of said disc corresponding to the length of the area on which adhesive is to be applied on the container, fiber-optic means sensitive to provide said signal as the length of light-colored material on the periphery of the disc passes thereby, whereby said fiber-optic means will terminate said signal as it reads the trailing edge of the light-colored material.
