Are respectively provided with the lower horizontal perforation lines 62.
Hereinafter, after explaining the mount with shrink film first, the details of the package of the present invention will be explained.

[Mount with shrink film]
7 to 10, the mount 5 with a shrink film includes a mount 2, a tubular shrink film 3, and an adhesive portion 4 that bonds the mount 2 and the shrink film 3.
By inserting the article 9 inside the cylindrical shrink film 3 and thermally shrinking the shrink film 3, the article 9 is held by the shrink film 3, and the article 9 is attached to the mount 2 via the shrink film 3. . The shrink film 3 has a cylindrical shape, but is normally folded into a flat shape as shown in FIGS. 7 to 10 before the article 9 is held.

The sheet material for forming the mount 2 is not particularly limited, and a conventionally known material can be used. Examples of the sheet material include cardboard (including cardboard laminated with thin synthetic resin films), synthetic resin sheets, synthetic resin sheets having a metal vapor deposition layer, foamed resin sheets, and laminated sheets thereof. It is done. The cardboard or synthetic resin sheet is preferably used because it is relatively inexpensive. Examples of the synthetic resin sheet include polyolefin-based, polyester-based, and polystyrene-based sheets, and polypropylene sheets are preferable because they have appropriate rigidity. Further, the mount 2 may be a laminated sheet obtained by laminating a plurality of sheet materials so as to be peeled, a laminated sheet obtained by folding a plurality of sheet materials and overlapping them. By using such a laminated sheet, the mount 2 having a large display area can be configured.
The thickness of the sheet material is not particularly limited, but is preferably about 0.2 mm to 1.5 mm. In the case of thick paper, it is about 0.5 mm to 1.5 mm, and in the case of a synthetic resin sheet, it is about 0.2 mm to 0.6 mm. Moreover, the desired design printing may be given to the surface or / and the back surface of the mount 2 as needed.

  The plan view shape of the mount 2 is formed in a substantially rectangular shape in plan view as shown in FIG. 7, but is not limited to this. For example, the mount 2 may be formed in a substantially triangular shape in plan view, a substantially elliptical shape in plan view, or the like (not shown). Moreover, in order to provide self-supporting property to the package 1, for example, leg pieces or the like may be formed on the mount 2 (not shown). A suspension hole 29 is formed in the upper part of the mount 2. But the said hole for suspension does not need to be formed.

The heat-shrinkable film used for constituting the cylindrical shrink film 3 has flexibility and further heats in at least one direction (one direction becomes the circumferential direction when formed into a cylindrical shape). If it is a film which has a contractibility, it will not specifically limit, A conventionally well-known film can be used. The heat-shrinkable film is obtained by forming a forming material containing a resin component, stretching it in at least one direction, and then heat-aging it at a required temperature.
The heat shrinkability refers to a property of shrinking when heated to a required temperature (for example, 70 ° C. to 100 ° C.). As the heat-shrinkable film, a film that slightly heat-shrinks or stretches in the other direction may be used. The other direction is a direction orthogonal to the one direction in the film plane.

The film forming material is not particularly limited, for example, polyester resins such as polyethylene terephthalate, olefin resins such as polypropylene, polystyrene resins such as polystyrene, cyclic olefin resins, biodegradable resins such as polylactic acid, Examples thereof include a resin composition containing, as a main component, one or a mixture of two or more selected from thermoplastic resins such as vinyl chloride resins. The shrink film 3 including a polyester-based resin film or a biodegradable resin film has a property of easily tearing in a heat shrink direction (a circumferential direction in the case of a cylindrical shrink film 35). For example, the shrink film 3 including a polyester resin film or a biodegradable resin film usually has a tear propagation strength measured in accordance with JIS K 7128-1 of 1.0 N / mm to 5.0 N / mm. . Since the shrink film 3 having such a property that it is easily torn in the heat shrink direction is easily cut along the upper and lower horizontal perforation lines 61 and 62 when the article 9 is rolled, it can be suitably used in the present invention.
The heat-shrinkable film may be a single layer or a laminate of two or more layers. When the heat-shrinkable film includes a biodegradable resin film or a polyester resin film and is a laminate, at least one of the layers is a biodegradable resin film or a polyester resin film.

The heat-shrinkable film may be an opaque film, but when design printing is applied to the cylindrical shrink film 3, it looks beautiful, so it is preferable to use a colorless transparent or colored transparent film.
Moreover, although the thickness of a heat-shrinkable film is not specifically limited, For example, they are 20 micrometers-100 micrometers.

The shrink film 3 is rolled so that one direction of the heat-shrinkable film is a circumferential direction, and one side end including the one side edge 3a is overlapped with the other side end including the other side edge 3b. The two side ends overlapped with each other are bonded to each other with a solvent or an adhesive to form a cylinder. The overlapped and bonded portion 3c is generally called a center seal portion, and this portion is hereinafter referred to as a center seal portion 3c.
The size of the cylindrical shrink film 3 can be appropriately set according to the article 9. In order to insert the article 9, the inner peripheral length of the cylindrical shrink film 3 is slightly larger than the maximum outer peripheral length of the article 9. The axial length of the tubular shrink film 3 may be the same as, or smaller or larger than, the axial length of the article 9.
When the cylindrical shrink film 3 having an axial length larger than that of the article 9 is used, the article 9 is inserted into the article 9 and heated so that the upper part and the lower part of the shrink film 3 Around the peripheral edge of the end surface, the upper part of the shrink film 3 wraps around and adheres to the peripheral edge of the end surface of the article 9, or the lower part of the shrink film 3 contacts the peripheral edge of the end face of the article 9 It goes around and comes into close contact.
In the illustrated example, a shrink film 3 having an axial length larger than the axial length of the article 9 is used. The shrink film 3 is attached to the surface of the mount 2 via an adhesive portion 4. The shrink film 3 is arranged so that the lower edge thereof substantially coincides with the lower edge of the mount 2. Further, as shown in FIG. 9, the shrink film 3 is bonded with its center seal portion 3 c facing the bonding portion 4. Thus, since the center seal part 3c is hidden from the front of the article 9 by adhering the band-like part including the center seal part 3c of the shrink film 3 to the adhesive part 4, it is possible to configure the package 1 that is preferable in appearance. However, the shrink film 3 may be bonded to the bonding portion 4 so that the center seal portion 3 c does not overlap the bonding portion 4.
The shrink film 3 is bonded to the mount 2 such that its axial direction is orthogonal to the lower edge of the mount 2. However, the shrink film 3 may be bonded to the mount 2 so that the axial direction is inclined at an acute angle with the lower edge of the mount 2.

  The bonding portion 4 is a layer that connects the mount 2 and the shrink film 3 and is made of an adhesive or a pressure-sensitive adhesive. The adhesive or pressure-sensitive adhesive is not particularly limited as long as it can firmly bond the mount 2 and the shrink film 3 respectively. Examples of the adhesive or pressure-sensitive adhesive include water-based adhesives, solvent-based adhesives, heat-sensitive adhesives, and pressure-sensitive pressure-sensitive adhesives. The water-based adhesive is an adhesive having fluidity in which a resin component is dissolved or dispersed in water, and is an adhesive that is solidified by drying. The solvent-type adhesive is an adhesive having fluidity in which a resin component is dissolved in a solvent, and is an adhesive that is solidified by volatilization. The heat-sensitive adhesive is an adhesive that does not exhibit tackiness at room temperature and that is tacky by heating and solidifies by cooling. The pressure-sensitive pressure-sensitive adhesive is a pressure-sensitive adhesive that exhibits adhesiveness at room temperature and maintains the adhesiveness for a long period of time. In particular, when the sheet material forming the mount 2 is cardboard, it is preferable to use a moisture-reactive hot melt adhesive from the viewpoint of adhesion to paper.

The bonding portion 4 is provided on the surface of the mount 2 and on a belt-like portion having a predetermined width extending in the axial direction of the shrink film 3. As shown in FIGS. 8 and 10, the bonding portion 4 does not reach the upper edge and the lower edge of the shrink film 3 and is provided corresponding to the midway portion in the axial direction of the shrink film 3.
For example, the bonding portion 4 is provided at a substantially central portion in the width direction of the mount 2, and the lower edge 4 d and the upper edge 4 c of the bonding portion 4 are separated from the lower edge and the upper edge of the mount 2.
The bonding portion 4 extending in a strip shape in the axial direction has two side edges 4a and 4b extending in the axial direction. In this specification, one side edge 4a of the bonding portion 4 is referred to as "first side edge 4a", the other side edge 4b is referred to as "second side edge 4b", and both are collectively referred to as "both side edges". .
The width of the bonding portion 4 (this width is the length between the first side edge 4a and the second side edge 4b) is not particularly limited. If the width is too small, when the article 9 is held on the shrink film 3, the weight of the article 9 cannot be endured, and the shrink film 3 may come off the mount 2. For this reason, the width of the bonding portion 4 is preferably 3 mm or more, more preferably 5 mm or more, and particularly preferably 7 mm or more. On the other hand, if the width of the bonding portion 4 is too large, it is difficult to open the shrink film 3 folded in a flat shape into a cylindrical shape. For this reason, the width of the bonding portion 4 is preferably 15 mm or less, and more preferably 12 mm or less. However, the width of the bonding portion 4 holds the shrink film 3 with an article having a cylindrical body having a diameter of about 1 cm to 7 cm or a non-cylindrical article having the same outer peripheral length as the cylindrical body. Is the case. When an article other than such an article (for example, a very large article) is attached, there may be no problem even if the width of the bonding portion 4 is outside the above range.
Further, the length in the axial direction of the bonding portion 4 is not particularly limited and can be set as appropriate, but if it is too short, when the article 9 is held on the shrink film 3, it cannot withstand the weight of the article 9, etc. There is a possibility that the shrink film 3 is detached from the mount 2. For this reason, 20 mm or more is preferable and, as for the length of the axial direction of the said adhesion part 4, 25 mm or more is more preferable. In the illustrated example, the axial length of the bonding portion 4 is substantially the same as the axial length of the article 9 to be held. However, the length in the axial direction of the adhesive portion 4 may be shorter than the length in the axial direction of the article 9 on the condition that the article 9 does not fall off or become unstable from the mount 2 via the shrink film 3.

In the surface of the shrink film 3, upper and lower horizontal perforation lines 61 and 62 and a pair of left and right vertical perforation lines 71 and 72 are formed. The upper horizontal perforation line 61 and the lower horizontal perforation line 62 extend in the circumferential direction of the shrink film 3, respectively, and the first and second vertical perforation lines 71 and 72 extend in the axial direction of the shrink film 3. The upper horizontal perforation line 61 and the lower horizontal perforation line 62 extending in the circumferential direction may be extended in a direction perpendicular to the axial direction when viewed from the flat shrink film 3, or Further, it may be inclined and extended with respect to a direction orthogonal to the axial direction.
In the present embodiment, the upper horizontal perforation line 61 and the lower horizontal perforation line 62 are extended in the circumferential direction in a state parallel to the direction orthogonal to the axial direction of the shrink film 3.

The first vertical perforation line 71 is provided at a position corresponding to the first side edge 4a of the bonding portion 4 or the vicinity thereof.
The upper end of the first vertical perforation line 71 is disposed at a position corresponding to the upper edge 4c of the adhesive portion 4 or the vicinity thereof. The lower end of the first vertical perforation line 71 is disposed at a position corresponding to the lower edge 4d of the bonding portion 4 or the vicinity thereof. That is, the first vertical perforation line 71 starts from a position corresponding to the upper edge 4c of the bonded portion 4 or the vicinity of the upper side thereof (or an end point), and is axially positioned at the first side edge 4a of the bonded portion 4 or the vicinity thereof. Is a perforation line having an end point (or start point) at a position corresponding to the lower edge 4d of the adhesive portion 4 or the vicinity of the lower side thereof. An upper horizontal perforation line 61 is connected to the upper end of the first vertical perforation line 71, and a lower horizontal perforation line 62 is connected to the lower end of the first vertical perforation line 71.
The second vertical perforation line 72 is provided at a position corresponding to the second side edge 4b of the bonding portion 4 or the vicinity thereof. The upper end of the second vertical perforation line 72 is also arranged at a position corresponding to the upper edge 4c of the bonding portion 4 or the vicinity of the upper side thereof, and the lower end of the second vertical perforation line 72 is also the lower edge 4d of the bonding portion 4 Or, it is arranged at a position corresponding to the lower vicinity thereof. An upper horizontal perforation line 61 is also connected to the upper end of the second vertical perforation line 72, and a lower horizontal perforation line 62 is also connected to the lower end of the second vertical perforation line 72.
In another expression, it can be said that the bonding portion 4 is provided in a belt-like portion between the first and second vertical perforation lines 71 and 72. Two belt-like portions between the first and second vertical perforation lines 71 and 72 can be considered in the circumferential direction of the shrink film 3, and one of them has a shorter interval between the vertical perforation lines.

  The first vertical perforation line 71 and the second vertical perforation line 72 may extend in the axial direction so as to coincide with the first side edge 4a and the second side edge 4b of the adhesive portion 4. The first vertical perforation line 71 and the second vertical perforation line 72 are provided on the first side edge 4a of the bonding portion 4 as shown in FIG. It is preferable to provide it corresponding to the outside vicinity and the outside vicinity of the second side edge 4b. When provided in the vicinity of the outside, the distance between the first vertical perforation line 71 and the first side edge 4a of the bonding part 4 and the distance between the second vertical perforation line 72 and the second side edge 4b of the bonding part 4 are particularly It is not limited and can be set appropriately. But when the said space | interval is too large (a vertical perforation line is separating too much from both side edges), when rolling the article | item 9, there exists a possibility that the shrink film 3 may not cut favorably. From this viewpoint, the distance is preferably 3 mm or less, preferably 10 mm or less, more preferably 5 mm or less, and particularly preferably 3 mm or less.

The upper horizontal perforation line 61 is provided at least above the bonding portion 4. Accordingly, the upper horizontal perforation line 61 may be formed only above the bonding portion 4 (in this case, the length of the upper horizontal perforation line 61 is substantially the same as the width of the bonding portion 4). In addition to the upper side of the bonding part 4, it may extend in the circumferential direction beyond the first side edge 4 a and / or the second side edge 4 b of the bonding part 4. In the illustrated example, the upper horizontal perforation line 61 is formed over the entire circumference of the shrink film 3.

The lower horizontal perforation line 62 is provided at least below the bonding portion 4. Accordingly, the lower horizontal perforation line 62 may be formed only below the bonding portion 4 (in this case, the length of the upper horizontal perforation line 61 is substantially the same as the width of the bonding portion 4). In addition to the lower part of the bonding part 4, it may extend in the circumferential direction beyond the first side edge 4 a and / or the second side edge 4 b of the bonding part 4. In the illustrated example, the lower horizontal perforation line 62 is formed over the entire circumference of the shrink film 3.

It extends in the circumferential direction at the position.

  In this case, the upper horizontal perforation line 61 and the lower horizontal perforation line 62 may extend in the circumferential direction so as to coincide with the upper edge 4c and the lower edge 4d of the bonding portion 4, but are provided in this way. Since the alignment is difficult in manufacturing, the upper horizontal perforation line 61 and the lower horizontal perforation line 62 are located near the upper side of the upper edge 4c and the lower edge 4d as shown in FIG. It is preferable to provide in the vicinity of the lower side. The vicinity of the upper side 4c and the lower side of the lower edge 4d of the bonding part 4 means a part that does not overlap the bonding part 4 in the vicinity of the upper edge 4c or the lower edge 4d of the bonding part 4. . When provided in the vicinity, the distance between the upper horizontal perforation line 61 and the upper edge 4c of the bonding portion 4 and the distance between the lower horizontal perforation line 62 and the lower edge 4d of the bonding portion 4 are not particularly limited and can be set as appropriate. . Since the shrink film 3 is cut well when the article 9 is rolled, the distance is preferably 3 mm or less, preferably 10 mm or less, more preferably 5 mm or less, and particularly preferably 3 mm or less.

Preferably, the article 9 has a shape that rolls easily when pushed out by rubbing with a hand. Examples of such a shape include a cylindrical shape, an elliptical cylindrical shape, a truncated cone shape such as a truncated cone shape and an elliptical truncated cone shape, and those having different-diameter barrels of these external shapes.
The article 9 in the illustrated example has a cylindrical body as a whole.

[Packaging]
The shrink film 3 folded in a flat shape of the mount 5 with the shrink film is opened, and the article 9 is inserted into the shrink film 3. At this time, the article 9 is inserted into the shrink film 3 so that the upper end of the article 9 is near the upper side of the upper horizontal perforation line 61 and the lower end of the article 9 is near the lower side of the lower horizontal perforation line 62. After insertion, the shrink film 3 is thermally contracted by applying heat at a required temperature. The shrinkable shrink film 3 has a central region on the outer peripheral surface of the body portion of the article 9, an upper portion of the shrink film 3 on the peripheral edge of the upper end surface of the article 9, and a lower portion of the shrink film 3 on the lower end surface of the article 9. It is in close contact with the periphery. In this way, the above-described package 1 as shown in FIGS. 1 to 6 is obtained.
In the package 1, the upper horizontal perforation line 61 is located between the upper end of the article 9 and the upper edge 4 c of the adhesive part 4, and the lower horizontal perforation line 62 is the lower end of the article 9 and the adhesive part 4. The upper end of the article 9 is positioned near the upper side of the upper horizontal perforation line 61 and the lower end of the article 9 is positioned near the lower side of the lower horizontal perforation line 62. ing. In the vicinity of the upper side, the distance between the upper end of the article 9 and the upper horizontal perforation line 61 is not particularly limited. For example, it is greater than 0 and equal to or less than 3 mm. Although the distance with the perforation line 62 is not specifically limited, For example, it exceeds 0 and is 3 mm or less.

When opening the package 1, as shown in FIG. 12, the hand A is pressed against the article 9 from the outside of the shrink film 3, and the hand A is placed on one side so that the article 9 rolls to one side in the circumferential direction ( Move to (indicated by the white arrow). In the example shown in FIG. 12, the right hand is placed on the article 9, moved to the left, and the article 9 is rolled counterclockwise when viewed from the lower end surface. Since the belt-shaped region in the axial direction of the shrink film 3 is bonded to the mount 2 in the bonding portion 4, when the article 9 is rolled to one side, the shrink film 3 is pulled, and among the side edges of the bonding portion 4, The tearing force concentrates on the side edge (first side edge 4a) opposite to the one side. When this tearing force acts on the first vertical perforation line 71, a cut line is generated along the first vertical perforation line 71, and the cut line extends upward from the upper and lower ends of the first vertical perforation line 71. Propagation to the horizontal perforation line 61 and the lower horizontal perforation line 62 occurs, and a broken line is generated in the direction of rolling the article 9 along the upper horizontal perforation line 61 and the lower horizontal perforation line 62 (see FIG. 13). Since the area B surrounded by the first vertical perforation line 71 and the upper and lower horizontal perforation lines 61 and 62 is separated from the article 9 by the cut line, the adhesion of the shrink film 3 to the article 9 is released, and the article 9 is It can be completely removed from the mount 2.
Furthermore, since the upper end of the article 9 is located near the upper side of the upper horizontal perforation line 61 and the lower end of the article 9 is located near the lower side of the lower horizontal perforation line 62, the packaging body 1 has a horizontal perforation line 61. , 62, the upper part 31 and the lower part 32 of the shrink film 3 are lifted from the article 9. For this reason, the article 9 can be easily removed from the mount 2 at the stage where the shrink film 3 is cut to about 1/3 to 1/2 of the entire circumference (even if the shrink film 3 is not cut over the entire circumference). It can also be removed.
In addition, that a cut line is generated along the vertical perforation line and the horizontal perforation line means that the cut line is generated substantially along the vertical perforation line and the horizontal perforation line. That is, in addition to the case where the broken line passes through all the through holes of the vertical perforated line and all the through holes of the horizontal perforated line, the broken line does not partially pass through the through hole, and the vertical perforated line Note that this may occur in the direction of the formation of the horizontal perforation line.

When the article 9 is removed from the mount 2, as shown in FIG. 13, it is divided into the first vertical perforation line 71 and the region B, the upper part 31 and the lower part 32 surrounded by the upper and lower horizontal perforation lines 61 and 62. The formed shrink film 3 remains adhered to the mount 2 through the adhesive portion 4.
According to the packaging body 1 of the present invention, even if the article 9 is not picked, it can be easily opened simply by moving the article 9 so as to be rolled by hand. Moreover, the mount 5 with the shrink film of the present invention can constitute the package 1 that can be easily opened just by inserting the article 9 into the mount 5 and thermally shrinking the shrink film 3. The package 1 of the present invention releases the close contact of the shrink film 3 even when the article 9 to be held has a size or shape that is difficult to pick, or even when the opener has difficulty picking the article 9 with an artificial nail or the like. 9 can be easily removed.
Although not particularly illustrated, when the article 9 is rolled to the other side in the circumferential direction at the time of opening (when the article 9 is rolled clockwise as viewed from the lower end surface as opposed to the direction shown in FIG. 12), A cut line is generated from the second vertical perforation line 72, and the close contact of the shrink film 3 can be similarly released.

  The package of the present invention is not limited to the above embodiment, and various design changes can be made within the intended scope of the present invention. Hereinafter, although the modification of this invention is demonstrated, in description of a modification, the description is abbreviate | omitted for the structure and effect similar to the said embodiment (as what was demonstrated), and a term and a code | symbol are used as it is. To do.

In the packaging body 1 of the above embodiment, the upper horizontal perforation line 61 is located between the upper end of the article 9 and the upper edge 4c of the adhesive part 4, and the lower horizontal perforation line 62 is the lower end of the article 9 and the adhesive part. Although not limited to this, the upper horizontal perforation line 61 coincides with the upper end of the article 9 and / or the lower horizontal perforation line 62 is located at the lower end of the article 9. The article 9 may be held by the shrink film 3 (not shown) so as to match the above. Thus, the packaging body in which the upper and lower ends of the article 9 and the positions of the upper and lower horizontal perforation lines 61 and 62 coincide with each other can be rolled and opened, and the article 9 can be easily detached from the mount 2.
14 and 15, the upper horizontal perforation line 61 is positioned between the upper end of the article 9 and the upper edge of the shrink film 3, and / or the lower horizontal perforation line 62 is provided on the article 9. The upper horizontal perforation line 61 corresponds to the upper end surface of the article 9 and the lower horizontal perforation line 62 corresponds to the lower end surface of the article 9 so as to be positioned between the lower end and the lower edge of the shrink film 3. The article 9 may be held on the shrink film 3 so that it is disposed. The arrangement of the upper and lower horizontal perforation lines 61 and 62 is such that the axial length of the shrink film 3 is set with respect to the axial length of the article 9, the position where the horizontal perforation line is formed, and the shrink film of the article 9. 3 can be implemented by appropriately adjusting the insertion position with respect to 3.
If the upper and lower horizontal perforation lines 61 and 62 are arranged corresponding to the upper end surface and the lower end surface of the article 9, it is difficult to generate a cut line along the horizontal perforation line at the time of opening. The upper horizontal perforation line 61 coincides with the upper end of the article 9 or is located between the upper end of the article 9 and the upper edge 4c of the adhesive portion 4, or the lower lateral perforation line 62 coincides with the lower end of the article 9 or It is preferable to be located between the lower end of the article 9 and the lower edge 4d of the bonding portion 4.

Moreover, in the said package 1 and mount 5 with a shrink film, as shown in FIG. 16, the cut line 81 may overlap with a part of 1st vertical perforation line 71, and may be formed. Similarly, a cut line 82 may be formed so as to overlap a part of the second vertical perforation line 72. The cut lines 81 and 82 are lines that divide the shrink film 3. The cut lines 81 and 82 may be arcuate or the like, but are preferably formed in a straight line. The cut lines 81 and 82 are formed in the middle part (preferably in the center in the vertical direction) of the first and second vertical perforation lines 71 and 72 as in the illustrated example. The lengths of the cut lines 81 and 82 are not particularly limited, but if the cut lines are too long, a large opening is generated in the cut lines 81 and 82 when the shrink film 3 is thermally contracted. May be damaged. From this point of view, the length of the cut lines 81 and 82 is preferably 10 mm to 20 mm. By forming the cut lines 81 and 82, when the package 1 is opened, the first vertical perforation line 71 is likely to be cut from the cut line 81, and the article 9 is rolled with a relatively small force to shrink film. 3 can be divided.
Furthermore, in the packaging body 1 and the mount 5 with the shrink film, a cut line 83 may be formed in the vicinity of a part of the first vertical perforation line 71 as shown in FIG. Similarly, a cut line 84 may be formed in the vicinity of a part of the second vertical perforation line 72. In the second modified example, the cut lines 81 and 82 are formed so as to overlap a part of the vertical perforated lines 71 and 72, but the cut lines 83 and 82 are formed in the vicinity of the vertical perforated lines 71 and 72 as in the present modified example. Even if 84 is formed, it is preferable because a cut line is likely to be generated from the cut line 83 to the first vertical perforation line 71 as in the second modification. In the vicinity, the distance between the cut lines 83 and 84 and the vertical perforation lines 71 and 74 is preferably within 2 mm, and more preferably within 1 mm.

  Moreover, in the said package 1 and mount 5 with a shrink film, as shown in FIG. 18, it has a substantially L shape in planar view ranging over the upper end part of the 1st vertical perforation line 71, and the upper horizontal perforation line 61. A cut line 85 may be formed. Similarly, a substantially L-shaped cut line 86 in plan view may be formed across the lower end of the first vertical perforation line 71 and the lower horizontal perforation line 62. Similar cut lines 87 and 88 may be formed between the upper and lower ends of the second vertical perforation line 72 and the upper and lower horizontal perforation lines 61 and 62. By providing such cut lines 85 and 86, the cut line generated along the first vertical perforation line 71 is easily propagated to the horizontal perforation lines 61 and 62 in a direction substantially perpendicular to the first perforation line 71 at the time of opening.

  Furthermore, in the packaging body 1 and mount 5 with a shrink film of the said embodiment, although two vertical perforation lines are provided, only one (for example, the 1st vertical perforation line 71) is provided. It is good (not shown). However, as in the above-described embodiment, the packaging body 1 provided with the first vertical perforation line 71 and the second vertical perforation line 72 has the article 9 placed in either the circumferential direction one side or the other side when opened. Even if it is rolled, it is preferable because a broken line is generated.

Further, in the packaging body 1 and the mount 5 with the shrink film of the above embodiment, both the upper horizontal perforation line 61 and the lower horizontal perforation line 62 are formed over the entire circumferential direction of the shrink film 3, For example, at least one of the upper horizontal perforation line 61 and the lower horizontal perforation line 62 may not be provided in the entire circumferential direction of the shrink film 3. For example, in the example shown in FIG. 19, the upper horizontal perforation line 61 is formed only above the bonding portion 4, and the lower horizontal perforation line 62 is formed only below the bonding portion 4.
Although not particularly illustrated, the upper horizontal perforation line 61 includes a position corresponding to the upper edge 4c of the bonding portion 4 or the vicinity of the upper side thereof, and is about ¼ to ¾ of the entire circumference of the shrink film 3. The lower horizontal perforation line 62 is formed up to about ¼ to ¾ of the entire circumference of the shrink film 3 including the position corresponding to the lower edge 4d of the adhesive portion 4 or the lower vicinity thereof. May be. Since the shrink film 3 (heat-shrinkable film) generally has a property of being easily torn in the circumferential direction rather than the axial direction, the horizontal perforation lines 61 and 62 are at least on the upper and lower edges 4c and 4d of the adhesive portion 4 or in the vicinity of the upper and lower sides thereof. By being formed to include the corresponding position, at the time of opening, the cut line propagates from the upper end and the lower end of the first vertical perforation line 71 to the upper and lower horizontal perforation lines 61, 62, and then the film According to the easy tearability, a cut line is generated in the circumferential direction, and the article 9 can be removed.

  Furthermore, in the packaging body 1 and the mount 5 with the shrink film of the above embodiment, the length in the axial direction of the adhesive portion 4 is set to be substantially the same as the length in the axial direction of the article 9. As shown, the axial length of the bonding portion 4 may be smaller than the axial length of the article 9. Also in this case, the first vertical perforation line 71 (and the second vertical perforation line 72) has its upper end disposed at a position corresponding to the upper edge 4c of the adhesive portion 4 or the vicinity thereof, and its lower end is the adhesive portion. 4 is arranged at a position corresponding to the lower edge 4d of the lower edge 4 or the lower side thereof, and the upper horizontal perforation line 61 and the lower horizontal perforation line 62 are the first vertical perforation line 71 (and the second vertical perforation line 72). Are connected to the upper end and the lower end of the.

In the packaging body 1 and the mount 5 with the shrink film of the above embodiment, the upper horizontal perforation line 61 and the lower horizontal perforation line 62 are formed in a direction orthogonal to the axial direction. For example, FIG. As shown in FIG. 5, the upper horizontal perforation line 61 and the lower horizontal perforation line 62 may be inclined in an acute angle with respect to a direction orthogonal to the axial direction and extended in the circumferential direction. In this case, one end of the upper horizontal perforation line 61 is connected to the upper end of the first vertical perforation line 71 and is formed in the circumferential direction obliquely upward from one end thereof, and the lower horizontal perforation line 62 has one end The portion is connected to the lower end of the first vertical perforation line 71, and is formed in a circumferential direction obliquely downward from one end portion thereof. The inclination angles α and β of the upper and lower horizontal perforation lines 61 and 62 can be set as appropriate. However, if the inclination angle is too large, it is difficult to cause a break in the circumferential direction of the shrink film 3 when the article is rolled during opening. From this point of view, the inclination angles α and β are independently greater than 0 and 60 degrees or less, preferably greater than 0 and 45 degrees or less, more preferably greater than 0 and 30 degrees or less.
In the modification shown in FIG. 21, the upper and lower horizontal perforation lines 61 and 62 are not provided in the entire circumferential direction. The upper and lower horizontal perforation lines 61 and 62 are provided above and below the bonding portion 4. And a configuration example in which only the first vertical perforation line 71 is provided (no second vertical perforation line 72 is provided). However, the present modification is not limited to the case where only the first vertical perforation line 71 is provided, and further, the second vertical perforation line is provided and the upper and lower ends of the second vertical perforation line are described above. Inclined upper and lower horizontal perforations may be connected (not shown).

Furthermore, since the upper and lower horizontal perforation lines 61 and 62 only need to extend in the circumferential direction, for example, as shown in FIG. The first horizontal perforation lines 611 and 621 inclined at an acute angle with respect to the direction orthogonal to the axial direction and the second horizontal perforation lines 612 and 622 parallel to the direction orthogonal to the axial direction may be included. . In this case, one end of the first horizontal perforation line 611 is connected to the upper end of the first vertical perforation line 71 and the other end is connected to the second horizontal perforation line 612. The first horizontal perforation line 621 has one end connected to the lower end of the first vertical perforation line 71 and the other end connected to the second horizontal perforation line 622. However, the first horizontal perforation line 611 may not be connected to the second horizontal perforation line 612, and the first horizontal perforation line 621 may not be connected to the second horizontal perforation line 622. In the illustrated example, the second horizontal perforation lines 612 and 622 are all formed over the entire circumferential direction, but may be partially formed in the circumferential direction.
The packaging body 1 in which the inclined upper and lower horizontal perforation lines 61 and 62 are formed also in the packaging body 1 in the circumferential direction of the shrink film 3 when the article is rolled, as in the above embodiment. 9 can be easily taken out.

Moreover, in the said package 1 and mount with a shrink film, the knob | pick part for opening may be formed in the upper edge of a shrink film (not shown).
In the present specification, the configurations of the above-described embodiment and various modifications have been described. However, the configurations can be appropriately selected and combined from these configurations within the scope of the present invention.
For example, the horizontal perforation line connected to the upper and lower ends of the first vertical perforation line extends in the direction orthogonal to the axial direction, and the horizontal perforation line connected to the upper and lower ends of the second vertical perforation line is the axis. It may be inclined and extended at an acute angle with respect to a direction orthogonal to the direction.
