Definitions

  • the invention is directed to a method of assembling thin-walled container halves.
  • a container is formed of thick-walled cylinder halves, one of which is necked out and the second necked in, the second half being telescoped into the first and the halves are then welded or brazed together.
  • This may be effective for thick-walled containers which retain their shape after reforming, but thin-walled containers, particularly if made from relatively soft metal such as aluminum; are very unstable in retaining their shape and thus are difficult to assemble and in forming the edges, are hard to control. This is especially significant for high-speed production of 400-1000 units per minute.
  • the object of this invention is to provide a novel container as well as a method and apparatus for assembling the container halves which overcome the foregoing problems.
  • the present invention provides a container having a pair of sections positioned end to end, each section having a thin-walled flexible metal body with an open end defined by an end portion, said end portions being telescoped and forming a lap seam, said end portions being radially spaced from each other in said - seam, characterized by an adhesive material in the space between said end portions bonding the same to each other, the adhesive being compressed between the end portions, and both of said end portions being loaded circumferentially.
  • the present invention also provides a method of bonding a pair of container sections end to end wherein each section has a metal thin-walled cylindrical body with an open end defined by an end portion having a raw edge comprising the steps of applying a bead of adhesive material of predetermined width on the interior side of the edge portion of one of said sections, and inserting the other section into said one section while applying a hoop stress to the end portion of said other section to reduce the diameter thereof to slightly less than the internal diameter of said one section, imbedding said end portion of said other section within said bead of adhesive while maintaining said end portion of the other section in radially spaced relation to said end portion of said one section to provide clearance therefrom and thereby leaving a film of adhesive material of predetermined thickness between the external side of the edge portion of the other section and the internal side of the edge portion of the one section, and then releasing the hoop stress on said end portion of said other section to cause excess bonding material to be squeezed out from therebetween and leaving a thin coating of said material therebetween.
  • the container sections are advanced toward each other at opposite sides of a die and the other or inner section is forced through a necking surface in the die and is slightly necked in while the one or outer section is disposed in receiving position.
  • the inner section may have a coating of adhesive applied thereto along its entering edge, although it will be understood the adhesive may be applied within the outer section at its juncture edge portion.
  • the outer section is held round (squared) in the die.
  • the entering portion of the inner section is slightly necked in while relatively advancing the two sections toward each other and while holding them under control so that the inner section easily enters the open end of the outer section.
  • the end portion of the inner section is under compression and after release from the die, springs. outwardly and produces a hoop tension in the end portion of the outer section.
  • the extent of insertion of the end portion of the inner section may be limited to less than the band width of the bead of adhesive so that the raw edge of the inner section is buried within the adhesive material.
  • the adhesive preferably is a vinyl ptastisot material which solidifies on being heated after the container sections are mated.
  • the container sections are released when telescoped and the inner section expands and compresses the trapped adhesive and thus maintains intimate pressed contact between the parts so that they adequately bond with the adhesive as it cures or sets.
  • Suitable adhesive materials for bonding the two container sections together can be any known materials having adhesive properties including vinyl plastisols, thermosetting epoxy resins and thermoplastic resins- such as polyethylene, polypropylene.
  • Other adhesive materials include vinyl plastisol formulations, carboxylated polyolefin resins and especially carboxylated polypropylene resins of the type disclosed in U.S. Patent 3,616,047.
  • FIGs 1 and 2 there are shown two can halves 2 and 3.
  • the upper can section 2 fits into a cylindrical bore 7 in a die assembly 4 and has its lower edge 5 seated upon an inwardly projecting shoulder 6.
  • the bore 7 is of a diameter slightly larger than the outer diameter of the- cylindrical body portion 8 of can section 2 which complementally fits into the bore 7.
  • the shoulder 6 extends radially inwardly of the inner surface of the upper can body 8 and defines an apical guide edge 10 with a frusto conical guide surface 12 open through the bottom side 14 of the die member 4.
  • the lower can body 14 is inserted into the guide 12 and is forced upwardly against the constricture imposed by the upwardly converging guide surface 12 which slightly compresses the open edge portion 16 of the can body 14.
  • the raw edge 18 of the inner or lower can body 14 is forced into the bead of adhesive 20 which may be vinyl plastisol or an epoxy.
  • the adhesive material 20 is laid onto the interior side of the upper container body adjacent to its lower edge and if it is of thermoplastic material it is heated so that the edge portion 16 may be forced into it.
  • the guide edge 10. causes the outer side 20 of the inner edge portion 16 to be spaced radially inwardly from the inner side 19 of the upper portion so that the adhesive is not scraped off by the edge 18 as it is inserted into the upper can body but a predetermined band layer 24 of adhesive material remains in the space 25 and also some of the adhesive material flows over the interior side 26 of the inner upper edge portion 16.
  • the inner edge portion 16 springs outwardly and compresses the adhesive material against the overlapping portion of the outer container section. The adhesive is thus compressively held between the two can parts and excess material is squeezed out so that an excellent thin adhesive bond is obtained which is stressed in shear when the container is filled with pressurized beverages for which this container is primarily intended and the gases load the ends axially.
  • the method of bonding the two can portions has been achieved which not only covers the raw edge of the inner section but also arranges the parts in a manner to obtain adequate adhesive at the interface and also the parts cooperate to squeeze out excessive adhesive material so as to obtain a good adhesive bond by utilizing the spring-back of the material which is preferably aluminum alloy of known kind such as H 19-3004 of about 0,15-0,28 mm (6-11 mils) in thickness although it is also contemplated that steel materials could be used.
