Definitions

  • the present invention relates to a packaging material comprising a packaging sheet opening mechanism.
  • packaging material Many kinds of the packaging material have been conventionally used for packaging each piece of food such as a sushi, confectionery or other items.
  • a packaging material illustrated in Figure 10 is for the sushi, and is used by forming a packaging sheet 100 made from a rectangular transparent plastic film, putting the packaging sheet 100 on a sushi 101 from an upper side so as to adhere closely thereto, folding and attaching an end edge of the packaging sheet 100 to the lower face of the sushi 101, and sealing an folded portion 102 by heating to prevent unnecessary opening (referring to Japanese Patent Application Laid Open No. 3(1991)-53858 ).
  • an primary objective of the present invention is to provide a packaging material having a opening mechanism capable of easily opening a package by only an one-touch operation of pulling an upper face of a packaging sheet packaging a food or other items in counter directions.
  • the packaging material is provided with a packaging sheet opening mechanism comprising a perforated line formed at a packaging sheet, and a belt-shaped cover sheet provided at the inside of the perforated line of the packing sheet so as to position the perforated line approximately at a center in the longitudinal direction, one side end edge in the longitudinal direction of the belt-shaped over sheet being adhered so as not to contact with the perforated line.
  • a transparent, translucent or opaque plastic film is used as the packing sheet and the belt-shaped cover sheet mentioned above.
  • the belt-shaped cover sheet is adhered to the packing sheet with heat sealing, in the packing sheet opening mechanism mentioned above.
  • the belt-shaped cover sheet is adhered to the packing sheet with an adhesive, in the packing sheet opening mechanism mentioned above.
  • the packaging material has the packaging sheet opening mechanism comprising the perforated line formed at a packaging sheet and the belt-shaped cover sheet provided at the inside of the perforated line of the packing sheet so as to position the perforated line approximately at the center in the longitudinal direction, the one side end edge in the longitudinal direction of the belt-like cover sheet being adhered so as not to contact with the perforated line.
  • FIG. 1 is a rectangular packaging sheet and has a packaging sheet opening mechanism 2 approximately at a center thereof in the longitudinal direction.
  • the transparent, translucent or opaque plastic film is suitable.
  • a plastic film comprising polypropylene, polyethylene, polyethylene terephthalate or the like, or a paper coated with these plastics is suitable.
  • a perforated line 3 is formed in overall length approximately at the center in the longitudinal direction of the rectangular packaging sheet 1. Further, a belt-shaped cover sheet 4 is provided at the inside of the perforated line 3 of the packaging sheet 1 so as to position the perforated line 3 approximately center in the longitudinal direction. Further, one side end edge in the longitudinal direction of the belt-shaped cover sheet 4 is adhered to the packaging sheet 1 so as not to contact it with the perforated line 3.
  • the belt-shaped cover sheet 4 may be adhered to the packaging sheet 1 with any one of heat sealing and an adhesive. 5 in the drawings is the adhering portion.
  • the rectangular packaging sheet 1 having the packaging sheet opening mechanism 2 illustrated in Figure 1 or 3 can be made by forming a roll 11 having a continuous packaging sheet opening mechanism 2 and cutting the roll 11 to have the predetermined length, as illustrated in Figure 9.
  • the packaging sheet 1 comprising the above constitution packages a packaged item 6 so as to provide the packaging sheet opening mechanism 2 approximately at the center of the upper face of the packaged item 6, as illustrated in Figure 5 or 8.
  • a round confectionery 6a is packaged with the packaging sheet 1, and the packaging sheet opening mechanism 2 is provided approximately at the center of the upper face of the round confectionery 6a.
  • a sushi 6b is packaged with the packaging sheet 1, and the packaging sheet opening mechanism 2 is provided in a diagonal direction on the upper face of the sushi 6b.
  • both sides of the perforated line 3 in the upper face of the packaging sheet 1 are pulled in counter directions while pressing the both sides by two fingertips respectively, to thereby tear the perforated line 3to the right and left.
  • the packaged item 6 inside the packaging sheet 1 can be easily taken out.
  • the belt-shaped cover sheet 4 covers the perforated line 3 of the packaging sheet 1 from the inside in a fitting state, it can be prevented that various germs, dust or the like that from the outside. Further, since the adhering portion 5 of the belt-shaped cover sheet 4 with the packaging sheet 1 is not contacted with the perforated line 3, there is no obstacle in the cutting work.
