Definitions

  • the present invention relates to a wrapping structure comprising an ovelap film for wrapping an object such as for example a tape cassette, a disk cassette and the like such that the overlap film can be opened easily, according to the preamble of claim 1.
  • Such a wrapping structure in known from e.g. EPA-62736
  • a box-shaped object to be wrapped such as, for example, a tape cassette, a disk cassette and the like is wrapped by means of an automatic wrapping machine as shown in FIG. 1.
  • reference numeral 1 denotes a box-shaped object to be wrapped such as a tape cassette, a disk cassette and the like
  • reference numeral 2 denotes a film roll formed by winding an overlap film made of heat shrink, thermal bonding type PP (polypropylene). From this film roll 2, a predetermined length of an overlap film 3 is cut out and the object 1 to be wrapped is wrapped in a so-called caramel wrapping style by means of the overlap film 3.
  • the object 1 to be wrapped is wrapped by means of the overlap film 3 and then an overlap area at ends of the overlap film is sealed by heat treatment (heat seal).
  • FIG. 2 shows an example of the wrapping structure by an overlap film which does not require this cutting film.
  • the overlap film 3 is a film having heat shrink, thermal bonding properties, made of PP or the like ordinarily used and is employed to wrap the box shaped object 1 to be wrapped such as a tape cassette, a disk cassette and the like in the so-called caramel wrapping style.
  • the overlap film 3 is heat-sealed at a portion where the ends thereof are overlapped with each other at the front of the object 1 to be wrapped (sealing portion 4 indicated by hatching) and further is heat-sealed at a portion where the ends thereof are overlapped with each other at the sides of the object 1 to be wrapped (sealing portion 5 indicated by hatching), so that the object 1 to be wrapped is wrapped in a sealed condition.
  • the wrapping structure of this overlap film 3 as shown in FIG. 2 and FIG. 3, has an opening mouth portion 6 at a part of the sealing portion 4 on the front side thereof.
  • the sealing portion 4 comprises bonding portions 4a by heat sealing and the opening mouth portion 6 formed in the center between the bonding portions 4a and has such a structure that when the overlap film is opened, the sealing portion 4 is peeled off by hooking the opening mouth portion 6 with the nail or the like at a fingertip.
  • the opening mouth portion 6 is formed by performing a mat print of an arrow shape on an inner surface (sealing surface) of the overlap film which overlaps on the upper side at the sealing portion 4.
  • this mat print 7 portion loses heat sealing performance (although those portions which are not printed have unimpaired heat sealing performance), so that printed portion serves as a non-bonding portion.
  • the opening mouth portion 6 formed by the mat print is structured so as to pop- up as shown in FIG. 3 and FIG. 4 by heat shrink at the time of heat treatment.
  • the nail or the like at a fingertip is hooked on the popped-up opening mouth portion 6 as shown in FIG. 6 so as to peel off the sealing portion 4, so that the overlap film 3 can be removed easily.
  • the opening mouth portion 6 is not sealed at all, it pop-up largely if it is subjected to heat shrink.
  • an object of the present invention to provide an overlap film wrapping structure in which an opening mouth portion is appropriately peeled to solve the above problem.
  • this is achevied by providing a weak bonding portion by dot print-on both sides of said opening mouth portion.
  • the opening mouth portion can be opened easily and kept to be peeled appropriately. Consequently, there is little fear that the opening mouth portion may be hooked and the sealing portion peeled out during distribution or the like, and the appearance is improved.
  • FIG. 7 shows a preferred embodiment of the overlap film wrapping structure according to the present invention.
  • a basic wrapping structure in the embodiment is the same as the above described conventional example.
  • An overlap film 3 is a film having heat shrink, thermal bonding properties made of PP as used ordinarily, or the like, and is employed to wrap a box-shaped object 1 to be wrapped such as a tape cassette, a disk cassette or the like in a so-called caramel wrapping style.
  • the overlap film 3 is heat-sealed at a portion where ends of the overlap film 3 are overlapped with each other at the front of the object 1 to be wrapped (sealing portion 4 indicated by hatching) and further is heat-sealed at a portion where side ends of the overlap film 3 are bent and overlapped with each other at the sides of the object 1 to be wrapped (sealing portion 5 indicated by hatching). Consequently, the object 1 to be wrapped is wrapped in a sealing condition.
  • the wrapping structure by the overlap film 3 has an opening mouth portion 6 at a part of the sealing portion 4 on the front of the object 1 to be wrapped.
  • the sealing portion 4 has such a structure that: it comprises bonding portions 4a which are bonded by heat sealing and the opening mouth portion 6 formed in the center between the bonding portions 4a; and when the overlap film 3 is opened, the sealing portion 4 is peeled by hooking the opening mouth portion 6 with the nail or the like at a fingertip.
  • This opening mouth portion 6 is formed by performing a mat print in an arrow shape on an inner surface (sealing surface) of the overlap film which overlaps on the upper side at the sealing portion 4.
  • this mat print 7 portion loses heat sealing performance completely (although portions which are not printed retain their heat sealing performance), so that printed portion serves as a non-bonding portion.
  • the opening mouth portion 6 formed by mat print is structured so as to pop-up by heat shrink at the time of heat treatment.
  • the nail or the like at a fingertip is hooked on the popped-up opening mouth portion 6 so as to peel-off the sealing portion 4, so that the overlap film 3 can be removed easily.
  • characters "OPEN” are printed substantially in the center of the mat print portion of the opening mouth portion 6 of the arrow shape, and this character portion is formed by dot printing.
  • This dot printing refers to a printing style in which print is made in a dot pattern formation using print varnish.
  • this dot printing 8 on the sealing surface of the overlap film 3 as shown in FIG. 10, the overlap film 3 is partially heat-sealed through gaps between the dots. That is, the portion of the dot print 8 has a heat sealing performance intermediate between the non printed portion and the mat printed portion (half seal).
  • the "OPEN" character portion formed by this dot print acts as a weak bonding portion 9 by the half seal.
  • the opening mouth portion 6 is the weak bonding portion 9
  • the opening mouth portion 6 is kept in appropriate peeling condition without largely popping-up, as shown in FIGS. 8, 9. This is evident if it is compared with the conventional example shown in FIGS. 3, 4.
  • the "OPEN" character portion is the weak bonding portion 9 by dot print
  • it is also permissible to form the weak bonding portion 9 by making the "OPEN” character portion as a non-printed portion that is, the "OPEN” character portion is formed by printing it in a so-called mortise in mat print).
  • the weak bonding portion 9 having the same heat sealing performance as the dot print can be ensured.
  • weak bonding portions 10 are provided by dot printing on the right and left sides of the mat print portion of the arrow shape of the opening mouth portion 6 in the sealing portion 4.
  • the weak bonding portions 10 are peeled easily, and then the bonding portions 4a are peeled continuously with this weak bonding portions 10.
  • the overlap film can be opened more easily.
  • the weak bonding portions by dot print are provided on both sides of the opening mouth portion, the opening procedure for the overlap film is further facilitated.
  • the weak bonding portion on the opening mouth portion is formed in a character form, it is possible to recognise a position of the opening mouth portion clearly according to the characters upon opening the overlap film. Thus, it is easy to open the overlap film.
  • this weak bonding portion may be formed, for example, as a graphic design or pattern such as an arrow or the like instead of the character form.
