Definitions

  • ABSTRACT A package for articles comprises a mounting paper having a multi-porous, thermosetting plastics layer bonded to its inner surface, and a covering having a thermoplastic layer bonded to its inner surface. The covering is heat sealed to the mounting paper at the respective peripheral edges.
  • PACKAGE This invention relates to a package capable of holding a surgical instrument or appliance between a mounting paper and a emering which are heat sealed at the respective surrounding side edges. particularly a package involving no unsatisfactory peeling-off of the mounting paper as often occurs during the unpacking operation.
  • thermoplastic coating on the peripheral surface of one sheet.
  • the multiporous coating is applied to a paper. then a poor bonding strength is disadvantageously obtained.
  • a proper temperature control is not effected in an attempt to thermally seal together these two sheets. the shape of these pores is deformed or destroyed at a high temperature involved. Where the shape of these pores is destroyed. both the sheets are firmly sealed through the respective coatings and difficulty is presented in opening the package.
  • An object of this invention is to provide a sanitary. inexpensive package capable of easily gaining access to a packaged article during the unpacking operation.
  • a package for surgical instruments in which a surgical instrument is enclosed between a mounting paper and a coy ering in a manner that the peripheral edge of these members is thermally scaled end to end: characterized in that a thermosetting plastics layer liming a multibore pattern is bonded to a mounting paper so that the thcrmosetting plastics layer can be. during the unpacking operation. removed up to a location where a medical instrument can be taken out. and a thermoplastics layer is bonded to all the inner wall of a covering OPPO- site to the mounting paper.
  • FIG. I is a perspective view of a package according to this invention.
  • FIG. 2 is a partial cross sectional view of the package in which a syringe is partly shown;
  • FIG. 3 is a partial cross sectional view showing a mounting paper and an outer covering of the package
  • FIGS. 4 to 7 are respectively plan views showing a thermosetting plastics layer applicable to the mounting paper of the package according to this invention.
  • FIG. 8 is a partial cross sectional view showing the mounting paper and outer covering of the package.
  • FIG. 9 is a partially enlarged view of FIG. 8.
  • the package according to this invention comprises a mounting paper I and an outer covering 5.
  • a surgical instrument such as a syringe 4 is enclosed. as shown in FIG. 2. between the mounting paper 1 and the outer covering of the package. in a manner that all the peripheral end portion of the package is heat sealed.
  • thermosetting plastics layer 2 having a plurality of cutouts or bores 3 as shown in FIGS. 4 to 7 is covered on the mounting paper 1 of the package according to this invention.
  • the bore 3. when considered from the ease with which the outer covering is stripped off from the mounting paper. is preferably in the geometrical. angular form as shown, for example, in FIG. 6.
  • Use is made. as a thermosetting plastics. of epoxy resins. unsaturated polyester etc.
  • various methods may be adapted. For example. a corresponding bore pattern coated on a drum for offset printing may be easily transferred on a mounting paper. A screen printing method may also be used for this purpose. Since the thermosetting plastics.
  • thermosetting plastics layer 2 is applied from the unsealed end section 8 up to a location at which a packaged article can be taken out.
  • the remaining thermosetting plastics-free section of the mounting paper and the corresponding thermoplastic. outer covering are thermally sealed together to form a strong bond as a whole. In this case. a thermosetting plastics can be saved by a corresponding amount.
  • the outer covering 5 is made of thermoplastic resins such as polypropylene. polycarbonate. saturated polymer etc. As shown in FIG. 3 a thermoplastics layer 6 for thermal scaling is covered all over the inner surface of the covering. Considered from the case in which the plastics layer 6 is thermally fused to form a bond with the thcrmosetting resin it is preferred that the plastics layer 6 have a lower melting point than that of the covering 5.
  • the package so formed is used for enclosing a surgical instrument or appliance.
  • the instrument or appliance is enclosed between the mounting paper I and the outer covering 5.
  • the outer peripheral portion of the covering 5 is heat sealed to the corresponding portion of the mounting paper 1.
  • the plastics layer 6 is softened and enters into the bores or cutout 3 of the plastics layer 2 to cause it to be bonded directly to the exposed portions of the mounting paper. Since the thermosetting plastics layer 2 is not susceptible to heat. the shape of the cutout is not changed. From this it will be understood that the unexposed surface of the mounting paper is intimately supported only by said directly bonded portion.
  • the package according to this invention is more germ-proof than the conventional counterpart in which a multi-porous. thermoplastic coating is applied around a sheet. This will be understandable from the fact that there is the likelihood of germs entering into a contacted portion between thermoplastic coatings and between a thermoplastic layer and a thermosetting plastics layer.
  • a sterilizing gas penetrates into the exposed portion of the mounting paper and a more rapid sterilization can be attained according to this invention than in a case where a thermosetting plastics coating is applied all over the surface of a mounting paper.
  • the covering is easily removed from the mounting paper through said unsealed end section of the cover ing. Since the plastics layer 2 is bonded to the surface of the mounting paper. the sealed portion formed between the mounting paper and the plastics layer 6 is retained as its peripheral area by a tension from the thermosetting plastics layer 2.
  • the outer covering 5 is bent as shown in FIG. 2 in a manner to seal or intimately contact the peeling-off end edge of the mounting paper. This arrangement permits no infiltration of germs and. during the unpacking operation, no access of germs to the sealed portion of a packaged article. Thus, a very sanitary package can be obtained.
  • (1) is a partial peel-off of the paper.
  • a moisture-proof. sterilizing gaspervious plastics film 9 is intimately bonded. as shown in FIGS. 2 and 3, on the outer surface of the mounting sheet. thus preventing swelling of the mounting paper due to moisture as well as infiltration of germs due to water content.
  • a package according to this invention constitutes a significant departure from the prior art counterpart. by applying on the mounting paper a thermosetting plastics layer having a multi-bore pattern. This arrangement prevents an unsatisfactory removal of a mounting paper from a covering as often encountered in the prior art.
  • a package can be manufactured at low cost without the need of employing as a mounting paper a high quality paper or an impregnated paper.
  • a package for an article such as surgical instrument comprising first and second sheets enclosing an article therebetween, said first sheet comprising a paper layer and a thermosetting plastics layer thereon. said thermosetting plastics layer extending over a peripheral portion of said paper layer and having a plurality of cutouts therein exposing underlying areas of said paper layer. and said second sheet comprising a layer of thermoplastic material. wherein said thermosetting layer on said peripheral portion of said first sheet is in contact with a peripheral portion of said thermoplastic material layer of said second sheet, said thermoplastic material of said second sheet extending through said cutouts in said thermosetting plastics layer and being bonded to said exposed underlying areas of said paper layer.
  • thermosetting plastics layer is formed from epoxy resin or unsaturated polyester.
  • said first sheet includes an outer moisture-proof plastics film provided on said paper layer.
  • thermoplastic material layer is turned down along an exposed edge of said paper layer to intimately contact and bond to said exposed edge of said paper layer.
  • a package for surgical instruments comprising first and second sheets enclosing a surgical instrument therebetween.
  • said first sheet comprising a paper layer having thereon a layer consisting of thermosetting plastics selected from the group consisting of epoxy resin and unsaturated polyester.
  • said thermosetting plastics layer extending over a peripheral portion only of said first sheet and having a plurality of cutouts of angular configuration therein exposing underlying areas of said paper layer.
  • said second sheet comprising a layer of thermoplastic material.
  • said layer of thermoplastic material being in contact with said thermosetting plastics layer with portions of the thermoplastic material extending through said plurality of cutouts and being bonded to said exposed underlying areas of said paper layer.
  • a portion of said thermoplastic material layer extending beyond said first sheet along one edge thereof adjacent said peripheral portion and being turned down along said edge in contact with and bonded to said edge of said first sheet.
