  • the vessels in accordance with this embodiment before they are used as material for vessels, are handled as combined vessels with vessel portions joined together by especially weak wall portions in sealed condition. It is when they are to be used as vessel material that they are separated at the specially weak line into bottomed cylindrical bodies 112 each having an open end, the vessels thus separated thereafter being shaped into vessels 1 16 of desired form.
  • the closed-ended cylindrical bodies 112 can be kept in excellent sanitary condition, perfectly free from impurities such as germs or foreign matters.
  • the separated vessels are subjected to molding operation just before they are used as materials for vessels, they remain less bulky until the molding operation is done, hence convenient to handle for transportation or storage.
  • the heating operation given to the cylindrical bodies 112 just before the use as vessel material serves to sterilize the interior 115 once again although they have already been sanitarized perfectly.

Between the convex peripheral edges 209 and 210, the combined vessel 204 is separated into two portions along the weak portion projected inwardly of the combined vessel 204 in the form of an acute angle.
  • the separated vessels 211, 212 of closed-ended cylindrical form thus obtained serve as vessels for commercial purposes or as material for vessels.
  • the tensile stress to be produced by bending the combined vessel 204 tends to takes place concentrically at the innermost portion of the weak wall which is inwardly projected in the form of an acute angle, so that the combined vessel 204 can be separated readily.
  • the inward projection of the weak portion 208 which forms an acute angle also acts to produce a notching effect at the innermost portion in the weak wall 208 when the combined vessel is bent and consequently, the notching effect also facilitates the separation of the combined vessel 204.
  • the especially weak portion 208 being projected inwardly of the combined vessel 204 in the form of an acute angle, further serves to guide correctly a cutting instrument such as an edged tool when it is pressed against the intermediate portion of the combined vessel 204 to separate the combined vessel 204 by mechanical cutting off operation. This ensures accurate and facilitated separation to be effected by mechanical cutting operation.
  • the peripheral edges at the mouths of separated vessels in the form of open-ended, bottomed cylinder obtained by separating the combined vessel 204 at the weak wall portion 208 are entirely free from strain or deformation and consequently, there is no need to modify or reform the shape of the mouths when the separated vessels 211, 212 are to be used, as they are, as vessels for commercial purposes or employed as vessel materials to be shaped into the form of desired vessels.
  • the convex peripheral edges 209, 210 as they are, form the mouth brims of the separated vessels 211, 212 obtained by separation as above described, the convex peripheral edges 209, 210, serving as the mouth brims when the separated vessels are used as finished products, can be utilized to great advantage for engagement with closures to be fitted thereto.
  • the convex circumferential edges 209, 210 on both sides of the especially weak portion 208 so formed in advance for separation of the combined vessel 204 can be utilized as they are for receiving a cap or cover therein.
  • the vessel is used for beverage use as a container, such as a milk bottle, whose mouth portion is to be kept in contact with the lip in drinking the contents, the provision of the convex brim serves to' make the vessel feel good to the touch when the brim is brought into contact with the lip.

  • EMBODIMENT 6 Referring to FIG. 16, a sixth embodiment of the present invention will be described below.
  • the side wall of a vessel or vessel material 501 is gathered together from circumferential portions so as to form a closed portion 502 of the combined vessel with a relatively short, linear fused fold 503 positioned diametrically at the center of each vessel forming the combined vessel and with fused folds 504, 504 each extending radially outwardly from each end of the short, linear fused fold 503, the distance between the axis and the extremities of the fused fold being smaller than that between the axis and the side surface of the vessel body.
  • fused folds 504, 504 formed by gathering the side wall of the vessel or vessel material 5.01 inwardly from circumferential portions and spaced apart at opposite ends of the linear fused fold 503 serves, at'the time of fusing operation, to restrict the movement toward the axis of .the vessel or vessel material of the fused sealing wall at the abovementioned two portions to a relatively small extent, this further preventing development of exceedingly great expansion of fused portions 503, 504 when the wall is gathered toward the axis to ensure strong fusion as desired.
  • the radially extending fused folds 504, 504 are spaced apart at two portions, the number of fused folds to be formed at the point where the radial fused folds 504, 504 are concentrated can be reduced as compared with the case where the fused folds 504, 504 are so concentrated as to extend radially from only, one portion, hence reliable fusing can be effected at the concentrated point.
  • the concentrated point of the fused folds is almost free from unexpected objections such as development of an opening to ensure disired fusing operation and yet, during vessel molding operation when the bottom wall is to be expanded, the bottom portion expands from each of the two separated points of concentration and as a result the entire bottom area is expanded with great ease to effect desired vessel molding and to thereby fulfil the objects stated in Embodiment 2.
  • EMBODIMENT 7 Referring to FIG. 17 a seventh embodiment of the present invention will be described.
  • the circumferential portion on opposite sides of the vessel or vessel material forming the combined vessel are gathered together inward to form a fused fold 553 in zigzag form, the distance between the axis and the extremities of each of the fused folds being smaller than that between the axis and the side surface of the vessel body.
  • all of the fused points forming the fused fold 552 can be formed by being gathered from two opposite sides.
  • a fused fold produced by being gathered from two sides markedly facilitates the fusing operation with high reliability.
  • the expansion of the bottom can be achieved uniformly over its entire area at the time of vessel molding operation and objects stated inEmbodiment 2 can thus be achieved.
  • inverted longitudinally aligned hollow articles which comprises extruding a tube of material from an extrusion nozzle, retaining the tube of material by suction while forming the body of the receptacle, deforming and sealing the tube of material to provide a closed end portion of a first receptacle, advancing the tube of material longitudinally relative to the extrusion nozzle a distance sufficient to compensate for subsequent formation of another inverted receptacle, forming longitudinally juxtaposed parallel annular channel areas in said tube of material to provide a weakened, frangible portion lying therebetween, deforming another portion of the advanced tube of material to provide a closed end portion of a second receptacle and severing the extruded material adjacent to said end portion to form separable receptacles.
