Method and apparatus for making dispensers

A method of attaching a reinforcing pressure sensitive adhesive label strip and a dispensing nozzle projecting therethrough to the outer surface of a flexible, imperforate wall of a closed, generally cylindrical, nondispensing package having an imperforate, collapsible wall and a longitudinal seam so that the nozzle is disposed on a seam-free portion of the wall intermediate the ends of the package, comprising continuously feeding a series of the packages along a given first path of travel;

• rotating the packages individually about their longitudinal axes until the seam of each package is located in a predetermined position;
• continuously feeding a series of nozzles, each having a flange and a projecting outlet and oriented with the projecting outlet downwardly along a second path of travel;
• continuously feeding a series of label strips closely spaced apart along a third path of travel, at least a portion of which lies in a plane common to a portion of the second path and in coincidence therewith and at least another portion of which lies in a plane common to a portion of the first path and in coincidence therewith, each of said strips having an aperture therein located intermediate the ends of the strip, the aperture being adapted to receive said nozzle, and each of said strips having a pressure sensitive adhesive coating on one surface thereof, the orientation of the label strips during their travel being such that the coated surface faces upwardly;
• inserting the projecting outlet of said nozzle into the aperture in said strip at the point of coincidence of the second and third paths while both said nozzles and strips are continuously moving so so to engage the flange of said nozzle with the adhesive coated surface of said strip;
• positioning the nondispensing package with its seam facing downwardly in the space between successive strips parallel to and near the end of a strip at the point of coincidence of the first and third paths while both said packages and strips are continuously moving;
• and rolling the positioned nondispensing package onto the near strip and the flange of said nozzle under pressure so that the strip is bonded to the outer surface of the imperforate, collapsible wall of said package by means of the adhesive coating, thereby reinforcing the imperforate wall while holding the nozzle against the imperforate wall at a location intermediate the ends of the package and away from the seam.

Apparatus for making a dispensing package with a dispensing nozzle positioned thereon from a closed, nondispensing package having an imperforate, collapsible wall and a longitudinal seam so that the nozzle is located on a seam-free portion of the outer surface of the closed package, comprising means for continuously moving a procession of the packages along a first path of travel, means in the first path of travel for uniformly positioning the seams of the packages, means for moving a procession of nozzles in a predetermined orientation along a second path of travel, means for continuously moving a succession of closely spaced pressure adhesive strips having an aperture therein intermediate the ends of the strips along a third path of travel, at least a portion of which lies in a plane common to a portion of the second path and in coincidence therewith and at least another portion of which lies in a plane common to a portion of the first path and in coincidence therewith, means for inserting a nozzle in the aperture at the point of coincidence of the second and third paths of travel, means for positioning a package in the space between successive strips at the point of coincidence of the first and third paths of travel so that the seam of each package is located parallel to and near an edge of a strip with nozzle, said package positioning means continuously moving said packages in unison with said continuously moving strips, and means for rolling the package under pressure onto the strip and nozzle.

Apparatus for attaching a reinforcing strip and a dispensing nozzle projecting therethrough to a collapsible, imperforate wall of a completed, closed, generally cylindrical package having a longitudinal seam so that the nozzle is located on a seam-free portion of the wall, comprising means for feeding a procession of the packages along a first path of travel, means for rotating each of the packages individually about its longitudinal axis until the seam reaches a predetermined position, means for orienting and moving a procession of nozzles along a second path of travel, means for feeding a supply of pressure adhesive strips having an aperture therein intermediate the ends of the strips along a third path of travel, the third path of travel including a portion lying in a plane common to a portion of said second path and in coincidence therewith and thereafter another portion lying in a plane common to a portion of said first path and in coincidence therewith, means for inserting a nozzle through the aperture of each strip at the point of coincidence of the second and third paths of travel, cradle adapted to receive one package at a time with the seam in said predetermined position from said means for rotating the packages near the point of coincidence of the first and third paths of travel, said cradle moving for a time in unison with the supply of labels in said third path and in relation to the labels so as to locate the package just above the labels and the seam of the package near one edge of a strip, and means for rolling the cylindrical package onto the strip at a point downstream of the point of coincidence of the first and third paths with the nozzles projecting outwardly from the package, whereby the strip conforms and adheres to the outer surface of the wall of each package and the nozzle is located on a portion of the wall away from the seam.
