Definitions

  • ABSTRACT As a method of packing, an article to be packed is roughly packed by a packing film with thermal contractibility; a band or strip like film, which may be adherent to the packing film by heat fusion, is temporarily attached to the packing film around its outer surface; and the packing film is brought into close contact with the article to be packed by utilization of the thermal contractibility of the packing film.
  • the softening and expansion of the packing film immediately before the packing film starts its thermal contraction during a single heating process, causes the adhesion between the packing film and the band or strip like film.
  • This invention relates generally to a method of packing, and more particularly to a method of packing in which an article to be packed ispacked by a packing film with thermal contractibility, and the packing film is placed in close contact with the article to be packed by heating.
  • Another packing method has been proposed, in which a band like film is fixed to a packing cellophane sheet by an adhesive agent, and the article to be packed is packed by the cellophane sheet with the band like film on the inside ofthe cellophane sheet, and then the packing cellophane sheet is closed by an adhesive agent.
  • one end portion of the band like film is exposed to the outside of the cellophane sheet.
  • the exposed end of the band film is pulled .to open the packing formed by the cellophane sheet.
  • a method of packing according to this invention comprises such steps that'an article tobe packed is packed or wrapped with a packing film having thermal contractibility, then the packing film is sealed, a band or strip like film which can be fixed to the packing film in heat fusion is temporarily attached to the packing film, and then they are heated at a predetermined temperaturc, whereby the packing film is brought into close contact with the article to be packed and at the same time the strip or band like film adheres to the packing film by heat fusion.
  • FIG. 1 is a perspective view of a disassembled record jacket to which the packing method of this invention is applied;
  • FIG. 2 is a perspective view of a record jacket wrapped with a packing film
  • FIG. 3 is a perspective view of the record jacket shown in FIG. 2 in which a band like film is roughly attached to the packing film;
  • FIG. 4 is a perspective view of the record jacket which is completely packed by the method of the invention.
  • FIGS. 5A, 5B and 5C, inclusive, are enlarged crosssectional views of a part of the record jacket used for explaining the heat fusion adhesion of the band like film to the packing film and the thermal contraction of the latter;
  • FIG. 6 is a perspective view used for explaining the unsealing of the completely packed record jacket
  • FIG. 7 is a perspective view of an example of the band like film used in the invention.
  • FIG. 8 is a perspective view of a cardboard case or carton which is completely packed by the packing method of the invention and in which articles packed by the packing method of this invention are accommodated.
  • a record jacket 1 generally consists of a thin square record jacket proper 4, which has formed along its upper end edge an opening 2 and accommodated therein a record 3, and a grip or cover 7 which has a pair of gripping members 5 and 6 and grips the opening 2 of the record jacket proper 4 to seal the latter.
  • the packing film 8 is desired to be made of such a synthetic resin that it is transparent or semi-transparent for viewing the record jacket 1 therethrough and has at least thermal contractibility.
  • a polyethylene film can be used as an example of such a packing film with thermal contractibility.
  • the polyethylene film also has heat fusion property.
  • reference numerals 9 and 10 indicate heat sealed portions of the packing film 8, respectively.
  • a band or strip like film 11 is temporarily attached to the packing film 8 along a desired line on the outer surface of the latter.
  • the strip 11 may be made of the material the same-as that of the packing film 8, but the material of the strip 11 is not needed to be limited to the same material as that of the packing film.
  • the strip 11 which is formed to be a ring by heat-sealing both ends of the strip 11 at a heat-seal portion 12 as shown in FIG. 7, is used.
  • one end portion 11a of the ring strip 11 is left free as a tip which will be used for opening the sealed packing.
  • the thus formed ring strip 11 is attached to the packing film 8 on its outer surface.
  • the ring strip 11 may be formed to have a size slightly larger than that of the packing film 8 covering the record jacket 1 loosely, but it is preferred that the ring strip 11 is of a size to be attached firmly to the packing film 8 (or that the packing film 8 be gathered by the ring strip 11 when the latter is attached to the former).
  • the packing film 8 and the strip 11 are contracted at temperature of, for example, about 200C.
  • the packing film 8 and the strip 11 are softened.
  • the packing film 8 which is of a shape as shown in FIG. A before it is heated, is expanded at temperature of about 100C due to the expansion of the sealed air therein which is heated and then is made to contact with the strip 11, as shown in FIG. 58.
  • the packing film 8 and the strip 11 are both softened, so that they adhere to each other.
  • both the packing film 8 and the strip 11 are contracted.
  • the temperature arrives at, for example, about 200C
  • the packing film 8 and the strip 11 are contracted completely as shown in FIG. 5C and they come into close contact with the record jacket 1 to seal up the same perfectly.
  • the end portion 11a of the strip 11 is pulled manually in the direction indicated by an arrow a shown in FIG. 6, and the packing film 8 is cut out along the strip 11 since the strip 11 firmly adheres to the packing film 8, as described above.
  • FIG. 8 A description will be now made with reference to FIG. 8 for the case where the packing method of this invention is applied to a cardboard box or a carton 15, in which articles or goods (not shown), for example, are accommodated.
  • the articles or goods are first inserted into the cardboard box 15 and then the cardboard box 15 is roughly wrapped by a packing film 18.
  • the other processes are carried out in the same manner as that described in connection with FIGS. 1 to 7 to completely pack or seal the cardboard box 15 with the packing film 18 and a strip 21 is also attached to the packing film 18 firmly.
  • the packing is opened, it is su fficient to pull a free end portion 21a of the strip 21 as in the foregoing 5 case.
  • the packing film is brought into close contact with the article to be packed by utilizing the thermal contractibility of the packing film when it is heated, and the band or strip attached to the outer surface of the packing film temporarily adheres to the packing film firmly by the softening thereof immediately before the packing film starts its thermal contraction.
  • the packing can be carried out at the time that the packing film is in close contact with the article to be packed.
  • the packing which is achieved by this invention when the packing which is achieved by this invention is opened, by pulling the free end of the strip or band the packing film can be easily cut out along the adhesion line of the strip to the packing film without injuring the article.
