Definitions

  • the present invention relates to a sealed bag with unsealing tape. More specifically this invention relates to a sealed bag with unsealing tape provided on the opening-part side of a packaging bag used for packaging foods, drugs or the like therein.
  • bags enable to be easily opened and closed by forming a zipper (an engaging device), which includes a male member and a female member, in an opening-part thereof have been used in many fields such as foods, drugs, daily commodities, and the like.
  • a zipper an engaging device
  • a section between the zipper and a seal part in the opening-part side of the bag is cut in, and then the bag is opened and resealed at the zipper part.
  • a user For opening a sealed bag, a user generally cuts the bag with the conventional type of scissors or tears a part to be cut in with hands from an end part thereof. To facilitate the operation of tearing the part to be cut in with hands, sometimes a notch is formed at a side edge of the bag.
  • Means 1 Formation of a perforated line as a line for tearing on the opening-part side
  • Means 2 Use of laminated film with the inner surface film relatively thick for forming a bag, and formation of a zipper on the inner surface film as well as a perforated line in a part outer from the zipper formed on the inner surface film and closer to an edge of the bag (Refer to Japanese Utility Model Publication No. S52-18254).
  • Means 3 Formation of a cutting-plane line having a specific form (Refer to Japanese Utility Model Publication No. S62-13838)
  • each of the means described above has the problems as described below.
  • the sealing performance is rather low because of the use of a perforated line, and sometimes the bag employing the means 1 may be opened during transportation or in other similar situations.
  • an inner surface side film with a perforated line formed thereon itself can be tone along a straight line, but when the inner surface side film is thermally fused and stuck to the base film, the perforations are filled with materials from the base film due to the thermal effect, which disadvantageously makes it difficult to tear the bag.
  • a main object of the present invention is to provide a sealed bag with unsealing tape which can provide the excellent sealing performance before its use and also which can easily be cut in and unsealed manually.
  • the present invention provides a sealed bag with unsealing tape provided on an opening-part side of a packaging bag
  • the sealed bad according to the present invention comprises band-shaped unsealing tape provided on one inner surface side of the bag and stuck there to in parallel to the opening part of the bag, and is characterized in that a cutout part is formed at an end part of the unsealed tape of the packaging bag on a surface opposite to the side on which the unsealed tape is stuck.
  • Adhesion of the unsealing tape is carried out by using an adhesive or thermally, for instance, by heat-sealing.
  • the tape of the present invention is not limited to the one with the large width, but can be the one with the small width, and even be the one having a form like a string so long as the tearing guide effect can be obtained. Tape with the relatively smaller width is preferable because the tearing guide effect is higher. However, when the width is large, the higher tensile strength can be obtained even if the thickness is small. When the width is small, the high strength can be obtained by making the thickness larger, and the so-called string-formed tape having an oval or circular cross section may be used in the present invention.
  • band-shaped unsealing tape is stuck on one inner surface of a packaging bag in parallel to the opening part thereof, and a perforated line or the like is not provided, and because of the configuration, there is not a space communicating to the outside, so that the excellent sealing performance before the packaging bag is opened is provided without fail.
  • a cutout part is formed on a surface opposite to the surface with the unsealing tape stuck thereon at an end part of the unsealing tape of the packaging bag, therefore the cutout part is present on one surface of the packaging bag as well as on one surface of the unsealing tape, so that the end part of the unsealing tape is exposed in the cutout part and the cutout par can easily be raised.
  • the sealed bag with unsealing tape it is preferable to form, on the packaging bag and/or on the unsealing tape, a pair of cut-in parts each cut in from an end part of the unsealing tape with the terminating edge present at a position inner from the end part of the unsealing tape.
  • a section between the cut-in parts functions like a tab, and the tab-formed section can be pinched as it is when unsealing the packaging bag, so that the operation for manually cut-in and unsealing the bag can easily be performed.
  • the cut-in parts are preferably arranged diagonally against the unsealing tape with the base edges of the cut-in parts arranged outside the unsealing tape.
  • cut-in parts can be formed correctly on one surface of the packaging bag as well as on the unsealing tape without fail.
  • the pair of cut-in parts get closer in a direction toward the depth of the bag (in which cutting-in is performed), so that the cut-plane line can be guided to a specified position (such as a center line of the unsealing tape), and a desired and correct cut-plane line can be acquired without fail, even if the work for cutting in is performed manually.
  • the unsealing tape is preferably drawn uniaxially in the longitudinal direction.
  • drawing means physically drawing a polymeric material into the fiber-like or film-formed state.
  • the strength or elasticity modulus of the polymeric material can be improved, and when a crystalline polymer is drawn at a temperature higher than the glass transition temperature but lower than the melting point, molecules in the non-crystalline portion are drawn in the drawing direction with the crystallinity improved and the molecules are oriented in the drawing direction. As a result, the tensile strength and elasticity modulus become larger.
  • Uniaxially drawing herein indicates drawing in one direction, and for instance, when a film is drawn uniaxially, the strength in the drawing direction becomes stronger than that in the vertical direction to provide an anisotropic material, and when the material is torn, the directivity for being torn in the drawing direction becomes higher.
  • the draw ratio should be 5 times or more, and preferably in the range from 8 to 12 times.
  • the unsealing tape is preferably made of polyolefin-based resin, and the polyolefin-based resin is preferably polyethylene-based resin or polypropylene-based resin.
  • polyethylene there can be enlisted polyethylene, polypropylene, polybutene and the like.
  • polyethylene-based resin there can be enlisted linear low density polyethylene (LLDPE), high density polyethylene (HDPE), low density polyethylene (LDPE) or the like.
  • LLDPE linear low density polyethylene
  • HDPE high density polyethylene
  • LDPE low density polyethylene
  • polypropylene for producing polypropylene-based resin there can be enlisted homopolypropylene, random polypropylene, block polypropylene and the like.
  • the unsealing tape is made of polyolefin-based resin, so that processing such as molding or drawing is performed easy because the polyolefin-based resin has the thermoplasticity, Further, the polyethylene-based resin is excellent in the dampproof capability, waterproof capability, cold resistance, and chemical resistance, and is well adapted to use for packaging a product in the liquid state.
  • the polypropylene-based resin has the small specific gravity, so that the resin can contribute to weight reduction of a packaging bag itself.
  • a zipper comprising a pair of male and female members is preferably stuck to both inner surfaces of the bag.
  • a zipper comprising a pair of male and female members is stuck to both inner surfaces of the bag, and the zipper can repeatedly be opened or closed, so that the sealing performance of the bag can be maintained.
