Definitions

  • containers or cans of metal are generally employed due to the obvious advantages of metal over many other materials for such containers.
  • engine oil packaged for sale to the typical motorist is packaged in a tubular metal container in relatively small quantities, the onequart capacity oil can being the most popular.
  • metal containers used for materials such as oil imparts numerous highly desirable features to such containers including strength and ruggedness so as to resist denting, weathering, puncturing and other damaging effects to which such a container is subjected during handling, shipment and the like.
  • Metal containers are also generally characterized by ready printability of the metal outer surface so as to provide an attractive and readily marketable product. Most importantly, metal is impermeable to the penetrating action of oil and other liquid materials and can be treated to be relatively inert to chemical attack by the packaged material.
  • paper is the most suitable substitute material for metal for containers and many efforts have been made to perfect a wound paper tube either convolutely or spirally wound in which liquid materials such as oil can be packaged and which is impermeable to the penetrating action of the oil.
  • the relatively low cost of paper and the highly developed techniques for winding paper tubes from which the container bodies can be made have brought about considerable development work leading up to such a container.
  • coated papers, laminated papers and the like provide a high degree of impermeability for the inner surface of the wound paper container bodies, the seam onthe inner wall of the container body is a source of leaking or wicking generally and efforts to produce an inexpensive impermeable container acceptable for the packaging of liquid and semiliquid materials have not met with .the desired degree of success.
  • metal for containers has other disadvantages in addition to high cost as disposal of empty metal oil containers has always posed somewhat of a problem due to the non-combustibility of the metal and the difiiculity of collapsing the metal container. Furthermore, the weight of the metal container is always a cost factor to consider when freight costs (are involved.
  • a primary object of this invention is to provide a new and novel method for making a leakproof container body using fibrous material such as paper.
  • Another object of this invention is to provide a new and novel method of forming a leakproof container body for an oil container utilizing fibrous material such as paper which is completely impermeable to penetrating liquids such as oil and which is inexpensive and rugged in construction.
  • a further object of this invention is to provide a new and novel method of spirally winding strip material including paper and metal foil into a tubular body for an oil container in which the spiral seam is completely sealed so as to prevent wicking or leaking of the liquid such as oil packaged in the container.
  • a still further object of invention is to provide a new and novel apparatus for making a leakproof body for the packaging of materials such as oil and the like.
  • Still another object of this invention is to provide a new and novel apparatus for spirally winding paper and metal foil strip material into a le-akproof composite oil container tubular body.
  • This invention further resides in the provision of a new and novel apparatus and method for spirally winding paper strips and foil laminated paper strips together to form a composite oil container tubular body in which the inner spiral seam is completely sealed against oil wicking and leaking and which tubular body may be readily closed at either end with metal ends or the like to provide a rugged, leakproot container of inexpensive construction utilizing readily available material and provided with a pleasing outward appearance.
  • the objects stated above and other related objects in this invention are accomplished by spirally winding a plurality of strips on anelongated rnandrel with adhesive therebetween to form a spiral tube severable into tubular container bodies.
  • the inner strip comprises oil impervious material such as foil laminated paper with the edges of adjacent convolutions in abutting relationship to form a spiral seam.
  • a relatively narrow strip of oil impervious material such as foil coated on its outwardly facing side with a thermoplastic adhesive is spirally wound between the inner strip-and the mandrel across the spiral but-t seam.
  • a portion of the mandrel adjacent the spiral tube forming end is heated to activate the thermoplastic adhesive on the narrow strip and adhesively secure the narrow strip to the inner strip to completely seal the seam.
  • the spiral tube is then cooled to set the thermoplastic adhesive and form an oil impervious ply for the container body.
