JP-A-9-58743

  However, as described above, when using a tape to fix the top / bottom part where the packaging film adhesive part is not provided to the plastic container, a separate tape is prepared in addition to the packaging film to wrap the plastic container. There is a problem that the operation of wrapping the plastic container becomes complicated.

  The present invention has been made in view of the problems of the conventional techniques as described above, and in a packaging film sheet in which a packaging film is continuous, without separately preparing means such as a tape, An object of the present invention is to provide a packaging film sheet capable of fixing a packaging film to a container at four longitudinal and lateral ends with the packaging film covering the opening of the container.

In order to achieve the above object, the present invention provides:
A packaging film sheet in which the packaging film fixed to the container at the four vertical and horizontal ends in a state of covering the opening of the container is continuously separated by a separation line,
The adhesive is applied to the area along both sides of the continuous direction in which the packaging film is continuous,
The separation line is
A first separation line extending in a direction orthogonal to the continuous direction inside a region where the adhesive is applied;
Two second separation lines that extend a predetermined length in the continuous direction and are connected to both ends of the first separation line at a part thereof;
From one end of each of the two second separation lines to the side opposite to the first separation line among the both sides in the continuous direction of the packaging film sheet, the direction orthogonal to the continuous direction. Two third separating lines extending in the direction;
From the other end of each of the two second separation lines to the side opposite to the first separation line in the continuous direction both sides of the packaging film sheet, orthogonal to the continuous direction It consists of two 4th separation lines extended in the direction.

  In the present invention configured as described above, when the packaging film sheet is separated by the separation line, the packaging film sheet is firstly arranged from both sides in the continuous direction of the packaging film sheet. Separation by 3 or 4 separation lines, then separation by 2nd separation lines connected to these 3rd and 4th separation lines, and then by 1st separation lines connected to 2nd separation lines It separates, and it will be separated by the film for packaging for every sheet. Here, in this state, either one of the third separation line and the fourth separation line extending from both sides in the continuous direction of the packaging film sheet is not separated. When the separation line is separated by the separation line that is not separated from the third separation line and the fourth separation line and the second separation line connected to the separation line, the second separation line, the third separation line, and the fourth separation line The area surrounded by the separation line and the side of the packaging film sheet is separated from the packaging film sheet. The packaging film separated from the packaging film sheet first has two end portions in the lateral direction by the adhesive applied to the areas along both sides in the continuous direction of the packaging film sheet in a state of covering the opening of the container. Is stuck and fixed to the container. And the adhesive is apply | coated to the area | region enclosed with the 2nd separation line, the 3rd separation line, the 4th separation line, and the side edge of the packaging film sheet isolate | separated from the packaging film sheet. Therefore, using this region as a tape, two end portions in the longitudinal direction of the packaging film are stuck and fixed to the container.

  In this way, in the packaging film sheet in which the packaging film is continuously separated by the separation line, the adhesive film is applied to the regions along both sides of the packaging film sheet. The end portion is adhered and fixed to the container, and the region is surrounded by the second separation line, the third separation line, the fourth separation line, and the side of the packaging film sheet. The two ends in the longitudinal direction of the packaging film will be adhered and fixed to the container, and the container film is covered with the packaging film without any additional means such as tape. The packaging film can be fixed to the container at the four ends.

  Moreover, if it is set as the structure by which the adhesive is not apply | coated to the area | region in which the 3rd separation line was provided among the areas along the continuous direction both sides where the packaging film of a packaging film sheet continues, 4th part The third separation line is easier to separate than the separation line, whereby the separation line that is separated when the first separation line is separated becomes the third separation line on both sides of the packaging film sheet, When the packaging film sheet is separated for each packaging film, the packaging film sheet is surrounded by the second separation line, the third separation line, the fourth separation line, and the side of the packaging film sheet. It is no longer difficult to tell which packaging film the area is used for. For example, when the packaging film sheet in a wound state is pulled out and separated for each packaging film, the packaging film sheet is separated for each packaging film if the front side in the drawing direction is the third separation line. First, only the packaging film is separated, and then remains on the packaging film sheet. The second separation line, the third separation line, the fourth separation line, and the packaging film sheet of the packaging film sheet. By separating the region surrounded by the side edges, the packaging film and the portion used for the packaging film instead of the tape are separated from the packaging film sheet.

  As described above, in the present invention, in the packaging film sheet in which the packaging film is continuously separated by the separation line, the adhesive film is applied to the regions along both sides thereof, whereby the packaging film Two end portions in the transverse direction of the film are adhered and fixed to the container, and the second separation line, the third separation line, the fourth separation line, and the side edges of the packaging film sheet Since the two ends in the longitudinal direction of the packaging film are adhered and fixed to the container by the region surrounded by, the opening of the container can be opened with the packaging film without separately preparing means such as a tape. The packaging film can be fixed to the container at the four vertical and horizontal ends with the portion covered.

  Moreover, in the area | region where the 3rd separation line is provided among the areas along the continuous direction both sides where the packaging film of the packaging film sheet continues, the 4th separation line The third separation line is easier to separate than the first separation line, so that the separation line that is separated when the first separation line is separated becomes the third separation line on both sides of the packaging film sheet. When the packaging film sheet is separated for each packaging film, the area surrounded by the second separation line, the third separation line, the fourth separation line, and the side of the packaging film sheet However, it does not become difficult to understand which packaging film is used.

  In this embodiment, as shown in FIG. 1A, a plurality of single-piece packaging films 3 made of a transparent material are continuously separated by a plurality of separation lines 5 to 8 and rolled onto a core material 2. This is a packaging film sheet 1 that is wound in a shape and drawn out from the state of being wound around a core material 2 and separated into individual packaging films 3 by these separation lines 5 to 8. In addition, the surface of the packaging film sheet 1 that is wound into the core 2 is adhered except for the region where the separation line 7 is provided in the region along both sides in the continuous direction where the packaging film 3 is continuous. The area | region where the separating line 7 is not provided among the area | regions along the continuous direction both sides where the film | membrane 3 for wrapping is applied is the sticking part 4. The pressure-sensitive adhesive for constituting the sticking part 4 is exposed on the inner surface of the packaging film sheet 1 wound around the core material 2, but the packaging film sheet 1 is wound around the core material 2. In the taken state, the adhesive film is not dried because the packaging film sheet 1 is attached to the pressure-sensitive adhesive inside the wound state inside the core material 2, and the adhesive is not dried. The packaging film sheet 1 can be pulled out of the wound state around the core material 2. Moreover, on the surface which becomes the winding state outer side to the core material 2 of the film sheet 1 for packaging, by applying a release agent along the continuous direction both sides where the film 3 for packaging continues, the film sheet 1 for packaging It is also conceivable to make it possible to easily pull out the material from the state of being wound around the core material 2.

  The separation line 5 is the first separation line in the present invention, and as shown in FIGS. 1A and 1B, the packaging film 3 is continuous inside the sticking portion 4. The perforations are formed by alternately and continuously extending the cut portions 5a and the tie portions 5b in a direction perpendicular to the direction, and the cut portions 5a are configured to be rounded at both linear ends. Is directed to the side opposite to the pulling direction of the packaging film sheet 1.

  The separation line 6 is the second separation line in the present invention, and is disposed at both ends of the separation line 5 as shown in FIGS. 1 (a) and 1 (c). It consists of two slits 6a and 6b arranged linearly in a continuous direction. The two slits 6a and 6b extend along the sticking portion 4 in a continuous direction in which the packaging film 3 is continuous, and one end of the slit 6a is separated on the extension line from both ends of the separation line 5. It is rounded and bent so as to go to the separation line 5 and is connected to the separation line 5. Then, a predetermined length extends from the rounded corner to the front side in the drawing direction of the packaging film sheet 1, and further rounded in a direction opposite to the separation line 5 on both sides of the packaging film sheet 1. It is bent towards One end of the slit 6b is disposed at a rounded corner of the slit 6a via a gap, and extends from the end to the winding direction side of the packaging film sheet 1 by a predetermined length. The film sheet 1 is rounded and bent in the opposite direction to the separation line 5 on both sides.

  The separation line 7 is the third separation line in the present invention, and as shown in FIGS. 1A and 1C, cut portions and tie portions are alternately and continuously formed. The shape of the cut portion is the same as that of the separation line 5. And the one end is arrange | positioned so that it may connect to the rounded and bent part of the slit 6a, and it is packaging from the one end to the side opposite to the separation line 5 among the both sides of the packaging film sheet 1. The film 3 is disposed so as to extend in a direction orthogonal to the continuous direction.

  The separation line 8 is the fourth separation line in the present invention, and as shown in FIGS. 1A and 1C, a micro-sewing machine in which cut portions and tie portions extend alternately and continuously. And one end thereof is arranged so as to be connected to the rounded and bent portion of the slit 6b, from one end thereof to the side opposite to the separation line 5 on both sides of the packaging film sheet 1, The packaging film 3 extends in a direction perpendicular to the continuous direction.

  A region surrounded by the separation lines 6 to 8 is a tape portion 9.

  As described above, the packaging film sheet 1 configured as described above is such that the separation lines 5 and 7 are rounded at both ends where the cut portions are linear, and the tips of both ends are the packaging film sheet 1. The blade shape is pressed against the packaging film sheet 1 and formed in the region where the separation lines 5 and 7 are provided. Is not applied, the adhesive does not adhere to the blade mold.

  Below, the effect | action at the time of isolate | separating the film sheet 1 for packaging mentioned above into the film 3 for packaging for every sheet | seat is demonstrated.

  FIG. 2 is a view showing a state in which the packaging film sheet 1 shown in FIG. 1 is separated into the packaging films 3 one by one.

  When the packaging film sheet 1 shown in FIG. 1 is separated into the packaging films 3 one by one, the packaging film sheet 1 wound around the core material 2 is pulled out and the core material 2 is fixed in the packaging state. When the film sheet 1 is pulled in the pulling direction, first, the breaking force is applied to both ends in the continuous direction of the packaging film sheet 1 where the packaging film 3 continues, and the separation line 7 is broken. At this time, the separation line 8 is provided in addition to the separation line 7 at both ends in the continuous direction of the packaging film sheet 1 where the packaging film 3 is continuous. As described above, the separation line 7 is provided. On the other hand, the adhesive is not applied to the area, whereas the adhesive is applied to the area where the separation line 8 is provided, so that the separation line 8 is not easily broken by this adhesive, The separation line 7 is broken without breaking the separation line 8. Moreover, since the separation line 7 has the same configuration as the separation line 5 shown in FIG. 1B as described above, it is possible to avoid the breakage region from being separated from the separation line 8. The operation is the same as that when the separation line 5 is separated, and will be described later.

  When the separation line 7 is completely broken, the slit 6a is connected to the separation line 7. Therefore, as shown in FIG. 2A, the broken portion is separated by the slit 6a. Reach both ends of 5. Here, after the separation line 7 is completely broken, the breaking force applied to the packaging film sheet 1 tends to be directed from the end of the separation line 7 to the front side in the drawing direction of the packaging film sheet 1. However, since the end of the slit 6a arranged to be connected to the end of the separation line 7 is rounded and bent toward the winding direction of the packaging film sheet 1, the packaging film sheet 1 is separated from the separation line 7. 7 is separated along the slit 6a without breaking to the front side of the packaging film sheet 1 in the pulling direction.

  When the packaging film sheet 1 is further pulled toward the front side in the pulling direction, the end of the slit 6a opposite to the separation line 7 is rounded so as to be directed to the separation line 5 so as to be connected to the separation line 5. Therefore, as shown in FIG. 2B, the broken portion of the packaging film sheet 1 is guided to the end of the separation line 5, and the separation line 5 is broken.

  Here, the action when the packaging film sheet 1 shown in FIG. 1 is separated by the separation line 5 will be described.

  FIG. 3 is a view for explaining the operation when the packaging film sheet 1 shown in FIG. 1 is separated by the separation line 5.

  When the broken portion of the packaging film sheet 1 reaches both ends of the separation line 5 and the packaging film sheet 1 is further pulled in this state in the drawing direction, as shown in FIG. In the tie portion 5b, a force that separates from the end of the cut portion 5a of the separation line 5 in the direction of arrow A in FIG. Therefore, in the tie part 5b, it is going to tear to the drawing direction front side of the film sheet 1 for packaging from the both ends of the cut part 5a.

  However, since both ends of the cut portion 5a are directed to the side opposite to the drawing direction of the packaging film sheet 1, in the tie portion 5b, the drawing film sheet 1 is drawn from the both ends of the cutting portion 5a. As a result, the cutting portion 5c of the tie portion 5b is less likely to face the front side in the pulling-out direction of the packaging film sheet 1, as shown in FIG. 3 (b).

  And as shown in FIG.3 (c), before the tie part 5b tears largely in the drawing direction front side of the film sheet 1 for packaging, the cutting part 5c reaches the adjacent cut part 5a, FIG.3 (d). As shown, the packaging film sheet 1 is separated into one packaging film 3.

  Since the packaging film 3 separated one by one breaks the separation line 7 out of the separation lines 7 and 8 as described above on both sides in the continuous direction where the packaging film 3 is continuous, As shown in FIG. 2 (c), on the winding direction side of the packaging film 3, a part of the packaging film 3 is cut out. Has the same shape. Thereby, as for the packaging film 3, the area | region inside the two sticking parts 4 is the drawing direction front side of the packaging film sheet 1, and the winding direction side about the direction which continued as the packaging film sheet 1 Each of the protruding flaps 3b is formed, and in the direction orthogonal thereto, a substantially cross in which flaps 3a protruding by the width of the sticking part 4 toward both sides in the continuous direction of the packaging film 3 are formed. It is the shape of.

  When the packaging film sheet 1 is broken by the separation lines 5 and 7 and the slits 6a to separate the packaging film 3 for one sheet, the winding film sheet 1 side of the packaging film sheet 1 is separated. In this state, the tape portion 9 constituted by the region surrounded by the separation line 8 and the slit 6b is projected. Then, as shown in FIG. 2 (d), the tape portion 9 is separated from the packaging film sheet 1 by breaking the separation line 8. When the separation line 8 is broken from both sides in the continuous direction of the packaging film sheet 1 of the packaging film 3, the other end side of the separation line 8 is rounded and bent in the extending direction of the slit 6b. When the separation line 8 is broken from the slit 6b side, the separation line 8 is rounded and bent from the direction in which the slit 6b extends. In any case, the separation line 8 is wrapped between the separation line 8 and the slit 6b. It is avoided that the film sheet 1 is avoided in a direction not following these. Thus, when the tape part 9 separates from the packaging film sheet 1, a part of the packaging film 3 to be separated next from the packaging film sheet 1 on the front side in the drawing direction is cut out. In addition, since the adhesive is not applied to the area where the separation line 7 is provided as described above, the separation line 7 breaks without breaking the separation line 8 when separating the packaging film 3. When the packaging film 3 is separated, the tape portion 9 protrudes toward the winding direction side of the packaging film sheet 1 of the separated packaging film 3, and the packaging film 3 is formed using the tape portion 9. It can be seen that it is fixed to the container.

  Thus, the packaging film 3 separated from the packaging film sheet 1 is fixed to the container in a state where the opening of the container is covered with the tape portion 9 separated from the packaging film sheet 1.

  Below, the usage method of the packaging film 3 isolate | separated from the packaging film sheet 1 as mentioned above is demonstrated.

  FIG. 4 is an external perspective view showing a plastic container to which the packaging film 3 shown in FIGS. 1 and 2 is attached.

  The packaging film 3 shown in FIGS. 1 and 2 is attached to a plastic container 11 as shown in FIG. As shown in FIG. 4, the plastic container 11 has a rounded opening 13 at a rectangular corner, and a flange 15 having a constant width outside the opening 13. And the foodstuff 12 is accommodated from the opening part 13. As shown in FIG. In this state, since the stored foodstuff 12 spills out from the opening 13, it is necessary to cover the opening 13 with the packaging film 3 shown in FIGS. 1 and 2.

  FIG. 5 is a view for explaining how to cover the opening 13 of the plastic container 11 shown in FIG. 4 with the packaging film 3 shown in FIGS. 1 and 2.

  When the opening 13 of the plastic container 11 shown in FIG. 4 is covered with the packaging film 3 shown in FIGS. 1 and 2, first, as shown in FIG. The packaging film 3 is overlaid on the top. At this time, the size of the portion of the packaging film 3 excluding the flap portions 3a and 3b is the same as that of the opening portion 13 of the plastic container 11, so that only the flap portions 3a and 3b of the packaging film 3 are plastic containers. 11 projecting from the opening 13 and the flange 15.

  Next, as shown in FIG. 5 (b), the flap portion 3a of the packaging film 3 is folded so as to wrap the plastic container 11, and the sticking portion 4 is stuck to the side surface of the plastic container 11, thereby The lateral ends of the packaging film 3 are fixed to the plastic container 11 respectively.

  Then, as shown in FIG.5 (c), the half of the tape part 9 isolate | separated from the packaging film sheet 1 is affixed on the flap part 3b of the packaging film 3, and this flap part 3b is wrapped so that the plastic container 11 may be wrapped. The vertical end of the packaging film 3 is fixed to the plastic container 11 by bending the tape part 9 on the side surface of the plastic container 11.

  Thus, in the packaging film sheet 1 in which the packaging film 3 is continuous, the adhesive is applied to the regions along both sides in the continuous direction in which the packaging film 3 is continuous. After covering the opening 13 of the plastic container 11 with the separated packaging film 3, the two end portions in the lateral direction of the packaging film 3 can be adhered and fixed to the plastic container 11 with this adhesive. The tape part 9 surrounded by the separation lines 6 to 8 of the packaging film sheet 1 and the side edges of the packaging film sheet 1 is separated from the packaging film sheet 1, and the tape part 9 allows the packaging film 3 to be separated. Plastic can be attached and fixed to the container 11 at two ends in the vertical direction, without using a separate means such as tape. 3 packaging film 3 while covering the opening 13 of the plastic container 11 in vertical and horizontal four end portions can be fixed to the plastic container 11 by.

  In addition, as described above, the size of the portion excluding the flap portions 3a and 3b of the packaging film 3 is the same as the opening portion 13 of the plastic container 11, while covering the entire opening portion 13, When the packaging film 3 is bent on the side surface of the plastic container 11, the end of the packaging film 3 does not protrude from the side surface of the plastic container 11.

(Other embodiments)
FIG. 6 is a view showing another embodiment of the packaging film sheet of the present invention, in which (a) is an external perspective view, and (b) is an enlarged view of part A shown in (a).

  As shown in FIG. 6, the present embodiment is different from that shown in the first embodiment in that the separation line 106 is composed of one slit, whereby the position of the separation line 108 is different. The separation line 106 in this embodiment is composed of only the slit 6a on the front side in the pulling direction out of the two slits 6a and 6b shown in the first embodiment, whereby the separation line 108 is separated from the separation line 5. It is arranged on the extension line.

  Also in the packaging film sheet 101 configured as described above, the packaging film sheet 101 is used by being separated into the packaging films 103 one by one, similar to the one shown in the first embodiment.

  FIG. 7 is a view showing a state in which the packaging film sheet 101 shown in FIG. 6 is separated into the packaging films 103 one by one.

  When the packaging film sheet 101 shown in FIG. 6 is separated into the packaging films 103 one by one, the packaging film sheet 101 wound around the core material 2 is pulled out and the core material 2 is fixed in the packaging state. When the film sheet 101 is pulled in the pulling direction, first, the breaking force is applied to both ends of the packaging film sheet 101 in the continuous direction in which the packaging film 103 continues, and the separation line 7 is broken.

  When the separation line 7 is completely broken, the separation line 7 is connected to the separation line 106. Therefore, as shown in FIG. The both ends of the separation line 5 are reached. Here, after the separation line 7 is completely broken, the breaking force applied to the packaging film sheet 101 tends to be directed from the end of the separation line 7 to the front side in the drawing direction of the packaging film sheet 101. However, since the end of the separation line 106 arranged to be connected to the end of the separation line 7 is rounded and bent toward the winding direction of the packaging film sheet 101, the packaging film sheet 101 is separated. Separation is performed along the separation line 106 without breaking from the end of the separation line 7 to the front side in the pulling-out direction of the packaging film sheet 101.

  When the packaging film sheet 101 is further pulled toward the front side in the pulling direction, the end of the separation line 106 opposite to the separation line 7 is rounded so as to be directed to the separation line 5 and is connected to the separation line 5. Therefore, as shown in FIG. 7B, the broken portion of the packaging film sheet 101 is guided to the end of the separation line 5, and the separation line 5 is broken.

  The packaging film 103 separated one by one by separating the separation line 5 is separated from the separation lines 7 and 108 as described above on both sides in the continuous direction where the packaging film 103 continues. Since it will break, as shown in FIG.7 (c), in the winding direction side of the film 103 for packaging, it has a shape where one part was notched. Thereby, the packaging film 103 is the flap part 3b in which the inner region of the two sticking parts 4 protrudes toward the winding direction side of the packaging film sheet 101 in the direction in which the packaging film sheet 101 is continuous. In the direction orthogonal thereto, a substantially convex shape is formed in which a flap portion 3a protruding by the width of the sticking portion 4 toward both sides in the continuous direction of the packaging film 103 is formed. Yes.

  When the packaging film sheet 101 is broken by the separation lines 5, 7, 106 and the single packaging film 103 is separated in this way, the separated packaging film 103 is moved to the winding direction side of the packaging film sheet 101. There is a tape portion 109 protruding from the packaging film sheet 101 via the separation line 108. Then, as shown in FIG. 7 (d), the tape portion 109 is separated from the packaging film sheet 101 by breaking the separation line 108.

  In this way, the packaging film 103 separated from the packaging film sheet 101 is the opening portion of the container using the tape portion 109 separated from the packaging film sheet 101 in the same manner as shown in the first embodiment. It is fixed to the container in a state of covering.

  In the present embodiment, the second separation line extends from both ends of the separation line 5 to the front side in the pulling direction of the packaging film sheet 101. However, the packaging film sheet from both ends of the separation line 5 is used. 101 may extend to the winding side.

  In addition, as the separation lines 5 to 8, 106, and 108 that can separate the packaging films 3 and 103 in the packaging film sheet 1 and 101 shown in the above-described embodiment, the above-described perforations and slits are used. In addition to the micro-sewing machine, the cut portions and the tie portions may be simply arranged alternately, and the separation lines 5 to 8, 106, and 108 may be formed of a single type.
