Abstract
Abstract A device for forming the body and bottom of a container of the kind wherein there is an axial seam formed by adhesively-joined overlapping portions of the side and a bottom formed by an upwardly-folded lower end portion of the bottom adhesively enfolded within a downwardly-folded portion of the lower end of the side, said device comprising an ultrasonic side seaming device for welding the side seam, said side seaming device embodying an elongate, ultrasonic horn and means therein defining a planar contact surface containing a stepped-down recess commencing several millimeters from one end for engagement with the side seam and a bottom seaming device comprising an outer mold containing a mold cavity for receiving the bottom, said outer mold containing a centrally-located circular hole, a shaft, a knurling tool supported by the shaft within the mold cavity for rotation about its axis and movement circumferentially within the hole and means circumferentially of the knurling tool defining a circumferential wall and an annular groove of such radial dimensions as to have rolling tangential engagement with the enfolded portion of the body and bottom when moved circumferentially within the hole to cause the enfolded portion to become adhered.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
197 words
A device for forming the body and bottom of a container of the kind wherein there is an axial seam formed by adhesively-joined overlapping portions of the side and a bottom formed by an upwardly-folded lower end portion of the bottom adhesively enfolded with a downwardly-folded portion of the lower end of the side, said device comprising an ultrasonic side seaming device for welding the side seam, said side seaming device embodying an elongate, ultrasonic horn and means therein defining a planar contact surface containing a stepped-down recess commencing several millimeters from one end for engagement with the side seam and a bottom seaming device comprising an outer mold containing a mold cavity for receiving the bottom, said outer mold containing a centrally-located circular hole, a shaft, a knurling tool supported by the shaft within the mold cavity for rotation about its axis and movement circumferentially within the hole and means circumferentially of the knurling tool defining a circumferential wall and an annular groove of such radial dimensions as to have rolling tangential engagement with the enfolded portion of the body and bottom when moved circumferentially within the hole to cause the enfolded portion to become adhered.
Claim 2
Independent Claim
197 words
A device for forming the body and bottom of a container of the kind wherein there is an axial seam formed by adhesively-joined overlapping portions of the side and a bottom formed by an upwardly-folded lower end portion of the bottom adhesively enfolded with a downwardly-folded portion of the lower end of the side, said device comprising an ultrasonic side seaming device for welding the side seam, said side seaming device embodying an elongate, ultrasonic horn and means therein defining a planar contact surface containing a stepped-down recess commencing several millimeters from one end for engagement with the side seam and a bottom seaming device comprising an outer mold containing a mold cavity for receiving the bottom, said outer mold containing a centrally-located circular hole, a shaft, a knurling tool supported by the shaft within the mold cavity for rotation about its axis and movement circumferentially within the hole and means circumferentially of the knurling tool defining a circumferential wall and an annular groove of such radial dimensions as to have rolling tangential engagement with the enfolded portion of the body and bottom when moved circumferentially within the hole to cause the enfolded portion to become adhered.
Claim 3
Dependent Claim
