Description

  TECHNICAL FIELD The present invention relates to a package that holds contents with an overlapped film, and more particularly to an opening structure of a package that has an easy-opening function and a function of preventing erroneous opening during transportation.

  It is useful that the package has a function of easy opening that can be easily opened by hand when the package is opened. As one of the easy-open packaging bodies, plastic packaging bodies that are easy peels that easily peel off the sealing (sealing) location due to weakened adhesive strength of the stacked films are widely used. ing.

  The package bonded with an easy peel is provided with an opening tab. The knob is an unsealed part where the superimposed film is not bonded. When the two pieces of the pick piece are picked and pulled, the adhered film is peeled off and the package can be opened.

  When such a package is opened, there are cases where the two films on the front and back of the unsealed portion are in close contact with each other. In this case, it becomes difficult to grasp the knob, and as a result, it is difficult to open the package. Therefore, measures are taken to make it easier to grasp the knob.

  In Patent Literature 1, the peripheral edges of the first sheet material and the second sheet material stacked on both sides of the preparation are adhered to each other to form a releasable adhesion portion, and the preparation is accommodated in an accommodation portion surrounded by the adhesion portion. A packaging body is disclosed in which each end of the first sheet material and the second sheet material on the close contact portion side is aligned while the other ends are shifted.

Utility Model Registration No. 3145234

  According to the configuration of Patent Document 1, it is possible to easily grasp the tabs provided on the other end sides at the start of opening, and to easily start the separation of the two first sheet materials and the second sheet material. It is supposed to be possible. Thus, by changing the length of one of the front and rear tabs and the length of the other tab, the tabs are easily grasped when the package is opened. If such a non-sealed part is fluttering, the adhesive part may be accidentally peeled off, for example, by being caught while the package is being transported or carried. And when it is made easy to grasp a pick piece like patent document 1, the possibility of mis-opening increases still more. Therefore, a measure for preventing erroneous opening of such a package is required. However, in such a package, it is difficult to express easy opening if erroneous opening is prevented.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a package that is excellent in the protection of contents, has easy opening while preventing erroneous opening, has a simple structure, and is easy to manufacture.

  In order to solve the above-mentioned problems, the present invention provides a packaging body that holds contents by a film that is overlapped, and the packaging body is sealed by a first seal portion, and the contents that hold the contents. In a direction along the second seal portion between the storage portion, the second seal portion in contact with at least a part of the outer edge of the package, the first seal portion, and the second seal portion. An unsealed portion including a corresponding virtual extension line, and has an opening or a cut through the film on the virtual extension line, the virtual extension line from each of the opening or both ends of the cut. Extending in the direction of the outer edge of the package, and having a first cut that intersects the imaginary extension line between at least one opening of the film, or one end side of the cut and the outer edge, The seal portion constitutes at least one of a knob portion that peels off the first seal portion, with the opening or the cut, the first cut, and a tear along the virtual extension line serving as an end portion. It is characterized by that.

  Furthermore, the first cut is characterized by intersecting the opening or a direction in which the virtual extension line extends from the one end side of the cut with an inclination angle.

  Furthermore, the angle formed by the first cut and the virtual extension line is 25 to 75 degrees.

  Furthermore, it has the 2nd notch which cross | intersects with the inclination angle with respect to the direction which the said virtual extension line extends from the said opening part in the other said film, or the other end side of an incision.

  Furthermore, an angle formed by each of the first cut and the second cut with respect to the virtual extension line is 105 degrees to 155 degrees.

  Furthermore, it has the 2nd notch which cross | intersects with an inclination angle with respect to the direction where the said virtual extension line extends from the said opening part in the other said film, or the said one end side of an incision.

  Furthermore, the angle formed by each of the first cut and the second cut is 105 degrees to 155 degrees with respect to the virtual extension line, and the angles formed by the first cut and the second cut differ from each other.

  Furthermore, the first cut and the second cut are all cuts penetrating from the front surface to the back surface of one film, or from the surface layer of any one of the front and back surfaces of the film. It is any one of the half cuts with a cut in the middle of the thickness direction.

  According to the packaging body of the present invention, in the packaging body that holds the contents with the overlaid film, the packaging body is sealed by the first seal part, and the contents storage part that holds the contents; A second seal part in contact with at least a part of the outer edge of the package, a first seal part, and a virtual extension line corresponding to a direction along the second seal part between the first seal part and the second seal part. The virtual extension line has an opening or notch penetrating the film on the virtual extension line, and the virtual extension line extends from the opening part or both ends of the cut to the outer edge of the package, respectively, There is a first cut that intersects the virtual extension line between the opening in the film or one end side of the cut and the outer edge, and the unsealed portion is the opening or cut, the first cut, and the virtual Along the extension Since the incision serves as an end portion and constitutes at least one of the knobs that peel off the first seal portion, there is a step between each break line formed by tearing each of the front and back two films. This makes it easier to grasp each knob. On the other hand, in a state before the film is torn, it is possible to prevent the packaging body from being unsealed. Therefore, it is possible to provide a package that is excellent in the protection of the contents, has easy opening while preventing erroneous opening, has a simple structure, and is easy to manufacture.

  Furthermore, according to the structure in which the first cut intersects with the opening or the direction in which the virtual extension line extends from one end side of the cut, each of the two front and back films is torn. Steps can be surely formed between the respective break lines formed by, so that the respective knobs can be easily grasped.

It is the top view in which the 2nd modification of the package was shown. It is the top view in which the 3rd modification of the package was shown. It is the schematic by which an example in which the opening part was pushed in when the package of FIG. 2 was opened was shown. FIG. 3 is a schematic view illustrating an example of a state after the package of FIG. 2 is torn when the package is opened.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. First, the configuration of the package according to the present embodiment will be described in detail. FIG. 1 is a plan view showing an example of a package 1 according to the present embodiment. In the following, for convenience of explanation, in the state of FIG. 1 where the packaging body 1 is placed, the side on which the breaking line is formed when the packaging body 1 is torn is up, and the front side of the figure is the front side. To do.

  As shown in FIG. 1, the packaging body 1 according to the present embodiment is configured such that the content 100 is held on a superposed film 10. And the package 1 is provided with the content accommodating part 2, the 1st seal | sticker part 3, the 2nd seal | sticker part 4, the non-seal part 5, the notch | incision 6, and the opening part 8 or the notch | incision. The external shape of the package 1 is, for example, a rectangle whose left and right width directions are short sides in plan view. From the viewpoint of the use efficiency of the film 10 at the time of bag making, the outer shape of the package 1 is preferably the illustrated rectangle or square. However, the external shape of the package 1 is not limited to a rectangle or a square, but may be a triangle, a polygon, a circle, an ellipse, or an irregular shape. The shape of the contents 100, the design of the product, etc. Depending on the design, it can be appropriately designed. Note that the package 1 according to the present embodiment is particularly effective when applied to a small package having a width direction of about several tens of millimeters.

  The package 1 is configured by overlapping two films 10 having the same shape. The opposing surface of the overlapped film 10 is sealed by a strip-shaped first seal portion 3 and a second seal portion 4 having a predetermined width. A content container 2 for holding the content 100 is formed in a region where the periphery is sealed by the first seal portion 3 extending in a band shape.

  In the illustration of FIG. 1, the shape of the 1st seal | sticker part 3 is made into the pentagon. The lower side of the first seal portion 3, the left side extending from both ends of the lower side, and the right side are in contact with the outer edge of the package 1. Then, the upper ends of the left side and the right side of the first seal part 3 extend to the middle of the packaging body 1 in the vertical direction. Furthermore, the 1st seal | sticker part 3 has two upper sides extended toward the inner side of the width direction of the package 1, and upper direction from each upper end of a left side and a right side. And the two upper sides are connected in the center of the width direction of the package 1.

  The 1st seal | sticker part 3 has adhere | attached the film 10 so that the heat seal intensity | strength which is easy to peel can be exhibited, and has easy peel property (easy peelability), ie, easy-open property. Such an adhesive that can be easily peeled and opened is also called a weak seal. The heat seal strength of the first seal portion 3 only needs to be such that a person can open it. Specifically, the heat seal strength of the first seal portion 3 is more preferably 4 to 8 N / 15 mm. Note that the heat seal strength of the first seal portion 3 may be even weaker when air does not enter the content storage portion 2 or when the content 100 is a thin plate. On the other hand, the lower side, the left side, and the right side of the first seal portion 3 may be strong seals that have higher heat seal strength than weak seals when peeling is not necessary. In addition, as a heat seal intensity | strength, there exists a thing by the measuring method based on JIS-Z-0238.

  On the other hand, the second seal portion 4 is an outer edge seal portion that contacts at least a part of the outer edge of the package 1. In the illustration of FIG. 1, the second seal portion 4 is in contact with the upper side of the package 1. If the configuration does not include the second seal portion 4, the unsealed region, that is, the overlapped films 10 in the unsealed portion 5 are used as the knobs, and the first seal portion 3 is Easy to peel. Therefore, there is a possibility that the first seal portion 3 for holding the contents 100 may be peeled off due to the pick portion being caught while the package 1 is being transported or carried. Therefore, in the present embodiment, by providing the second seal portion 4, the overlapped films 10 in the package 1 are not easily grasped, and the first seal portion 3 is not intended. It is prevented that it peels off.

  The second seal portion 4 is required to be configured not to expose the knob that opens the first seal portion 3 of the package 1. For this reason, the 2nd seal | sticker part 4 is made into the shape along the outer edge of the package 1, and also the opportunity for peeling of 2nd seal part 4 itself is not formed in the outer edge of the package 1. Made. And when the 2nd seal | sticker part 4 is formed in contact with the outer edge of the package 1, even if it is a weak seal, the package 1 is difficult to open. Therefore, the structure of the above-described second seal portion 4 prevents the packaging body 1 according to this embodiment from being unintentionally peeled off in the initial state.

  In the illustration of FIG. 1, the first seal portion 3 is in contact with the three outer edges of the package 1. However, for example, when the second seal portion 4 is in contact with all four outer edges of the package 1, the first seal portion 3 is not in contact with the outer edge of the package 1. It doesn't matter. More specifically, this is the case, for example, in which each configuration of the content container 2 / the first seal portion 3 / the unsealed portion 5 / the second seal portion 4 is circular from the inside.

  The second seal portion 4 is not necessarily required to be a weak seal. However, it is advantageous that the second seal portion 4 is easily peeled off when the package 1 is opened according to the procedure described later. Even if the tear of one film 10 reaches the second seal portion 4, even if the second seal portion 4 peels off, the tear of the other film 10 does not follow, This is because the propagation of tears in one film 10 proceeds. Furthermore, for example, when the first seal portion 3 is a weak seal and the second seal portion 4 is a strong seal, a weak seal material is applied to the first seal portion 3 when the package 1 is manufactured. This is a measure that only the second seal portion 4 is not provided with the weak seal material. Therefore, the second seal portion 4 is preferably a weak seal.

  A region outside the first seal portion 3 is an unsealed portion 5 in which the opposing surface of the overlapped film 10 is not sealed. The unsealed portion 5 is located in a region between the first seal portion 3 and the second seal portion 4, and in the illustration of FIG. 1, below the second seal portion 4 and in the first seal portion. 3 is located above the upper side. By providing the unsealed portion 5, the first seal portion 3 and the second seal portion 4 are not connected. And the outer edge of the package 1 becomes an end seal by the first seal portion 3 and the second seal portion 4 except in the region of the unsealed portion 5. The packaging body 1 having such a configuration has the first seal part 3 and the second seal part 4 having an easy peel property, as long as the opening end, that is, a trigger is not provided, even if the heat seal strength of the second seal part 4 is weak. The package 1 cannot be opened easily.

  The unsealed portion 5 is preferably set to a predetermined distance L or less at the outer edge of the package 1. That is, it is preferable that the distance between the first seal portion 3 and the second seal portion 4 is set to a predetermined distance L or less at the left and right outer edges of the package 1. More specifically, the unsealed part 5 is designed at the outer edge of the package 1, for example, to such a length that a human finger does not enter. Thus, the unsealed part 5 can suppress more the situation where the package 1 opens unintentionally by being made into the predetermined distance L or less in the outer edge of the package 1. FIG.

  The package 1 is configured such that the second seal portion 4 is removed from the package 1 by tearing the region of the unsealed portion 5 along the second seal portion 4. When the contents container 2 or the first seal part 3 side is separated from the second seal part 4 side, a tear proceeds (propagates) from the opening end of the package 1 and the outer edge of the package 1 An extension line in a direction assumed to reach (at least one of the left and right ends) is referred to as a virtual extension line 7. That is, the unsealed portion 5 includes a virtual extension line 7 corresponding to the tearing direction of the film 10 between the first seal portion 3 and the second seal portion 4 in the region.

  It is preferable that the virtual extension line 7 has a certain distance from the upper end of the first seal portion 3. This is because when the second seal portion 4 is removed from the package 1, the gap between the virtual extension line 7 and the first seal portion 3 becomes a knob portion described later, and the ease of gripping is affected. This is because that.

  The package 1 has an opening 8 that penetrates both the superimposed films 10 on the virtual extension line 7. The opening 8 is preferably provided near the center in the width direction of the package 1. The opening 8 is an opening extending in the width direction of the package 1 or a cut. However, both ends of the opening 8 are positioned away from the left and right outer edges of the package 1. The length of the opening 8 depends on the dimensions of the package 1, particularly the length in the width direction, but if it has a total length of 5 mm or more, it functions as an unsealed end and is preferably about 10 mm in total length. One opening 8 may be provided in the region of the unsealed portion 5 of the package 1. Instead of the opening 8, a cut that does not penetrate the film 10 may be provided.

  The wrapping body 1 has a virtual extension line 7 between one end side (here, the left side) of the opening 8 in at least one of the two films 10 that are superimposed, and the outer edge (here, the left end) of the wrapping body 1. And a cut 6 corresponding to at least one first cut. FIG. 1 illustrates a package 1 having one notch 6 on the left side in the width direction within the region of the unsealed portion 5 in the front film 10.

  The notch 6 is a full cut that penetrates from the front surface to the back surface of one film 10, or a half cut that has a cut from one surface layer of the film 10 or the back surface to the middle of its thickness direction. Any of these processes has been made. The package 1 according to the present embodiment uses, for example, a cut 6 processed by full cut. In addition, the cut 6 formed in the package 1 of this embodiment may be a full cut, a half cut, or both. However, from the viewpoint of manufacturing efficiency, it is preferable to use either a full cut or a half cut.

  According to the configuration in which the notch 6 is either a full cut or a half cut, it is easy to manufacture and, in addition, is effectively grasped as a knob between the respective break lines in the two films on the front and back sides. An easy step can be formed.

  The notch 6 intersects with an inclination angle with respect to the direction in which the virtual extension line 7 extends from one end side of the opening 8. More specifically, in the region of the unsealed portion 5 of the package 1, a notch 6 is formed with respect to a direction (here, the left direction) in which the virtual extension line 7 extends from one end side (here, the left side) of the opening 8. , Extending toward the first seal portion 3 so as to cross downward. Note that the direction of the cut 6 may be reversed. That is, the cut 6 may be arranged so as to extend upward toward the second seal portion 4 and intersect with the direction in which the virtual extension line 7 extends.

  The cut 6 has an angle within a predetermined range with respect to the virtual extension line 7. FIG. 1 shows an example in which the angle α1 formed by the virtual extension line 7 and the cut 6 is 60 degrees. Here, the angle between the virtual extension line 7 and the notch 6 extending to the upper side of the package 1 is used with reference to the virtual extension line 7 extending from the intersection of the notch 6 to the opening 8 side.

  The notch 6 having a predetermined angle with respect to the virtual extension line 7 is changed by passing the direction of the tear propagated to the notch 6 along the virtual extension line 7 through the notch 6 when the film 10 is torn. It has the function to do. Therefore, the break line formed by the crack that propagates through the notch 6 has a shape having a step in the vertical direction in the region of the unsealed portion 5. The unsealed portion 5 from which the second seal portion 4 has been removed has an opening 8, a notch 6, and a tear along the imaginary extension line 7, and the first seal portion 3 is peeled off. Configure at least one of the knobs

  On the other hand, a tear generated when the other film 10 (back film) not having the notch 6 is torn propagates substantially on the virtual extension line 7, and a break line formed by the propagated tear is an unsealed portion 5. In this region, the shape does not have a step in the vertical direction. The unsealed portion 5 from which the second seal portion 4 of the other film 10 has been removed is the other of the knobs that peel off the first seal portion 3 by a break line formed on the substantially virtual extension line 7. Configure.

  The packaging body 1 according to the present embodiment having such a configuration has a step between each break line formed by tearing each of the two front and back films 10, and each grip portion is gripped. It becomes easy. On the other hand, in the state before the film 10 is torn, the situation where the package 1 is accidentally opened can be prevented. Furthermore, since the notch 6 and the opening 8 are formed in the unsealed portion 5, the protection of the contents is not affected. Therefore, it is possible to provide a package 1 that is excellent in the protection of the content 100, has easy opening while preventing erroneous opening, has a simple structure, and is easy to manufacture.

  In addition, in the structure which does not have the notch | incision 6, there is almost no level | step difference in each break line (edge part of a knob | pick part) formed when each of the film 10 of 2 sheets of front and back is torn, and a knob | pick part It is hard to grasp.

  It is preferable that the angle α1 formed by the virtual extension line 7 and the cut 6 described above is an acute angle of 25 to 75 degrees. If angle (alpha) 1 is 25-75 degree | times, the level | step difference which can be easily grasped as a knob | pick part can be formed between each breaking line in the film 10 of 2 sheets of front and back. The angle α1 formed by the virtual extension line 7 and the notch 6 may be an obtuse angle of 105 to 155 degrees. Even if the angle α1 is 105 to 155 degrees, it is possible to form a step that can be easily grasped as a knob between the break lines in the two front and back films 10.

  The cut 6 depends on the size of the package 1 and the angle α1 formed with the virtual extension line 7 described above, but it may be about 10 mm in total length. In addition, in FIG. 1, the linear notch 6 is illustrated. However, the notch 6 may be arcuate or S-shaped, for example. The direction of the tear can be induced by forming the notch 6 in a curved shape.

  Next, the structure of the modification of the package 1 is demonstrated in detail. FIG. 2 is a plan view showing a first modification of the package 1. The package 1 according to the first modification has a cut 6 having a form different from the configuration of the above-described embodiment. In FIG. 2, not only one film 10 (front film) has a cut 6 corresponding to the first cut, but the other film 10 (back film) also has a cut 6 corresponding to the second cut. A package 1 is illustrated. Other features are the same as those in the above-described embodiment.

  In the region of the unsealed portion 5 in one film 10 of the package 1, a notch 6 is formed in the direction (left direction) in which the virtual extension line 7 extends from one end side (here, the left side) of the opening 8. The second seal portion 4 is provided so as to extend in the upward direction toward the second seal portion 4. FIG. 2 shows an example in which the angle α2 formed by the virtual extension line 7 and the cut 6 is 120 degrees. On the other hand, the packaging body 1 according to the first modification further has a notch 6 that intersects with an inclination angle with respect to the direction in which the virtual extension line 7 extends from the other end side of the opening 8 in the other film 10. Have. More specifically, in the region of the unsealed portion 5 in the other film 10 of the package 1, with respect to the direction (right direction) in which the virtual extension line 7 extends from the other end side (right side here) of the opening 8. The notch 6 is provided so as to extend in the upper direction toward the second seal portion 4. FIG. 2 shows an example in which the angle α3 formed by the virtual extension line 7 and the cut 6 is 120 degrees.

  In the left notch 6, the tear of one film 10 has a shape having a step toward the upper side, whereas the tear of the other film 10 propagates on the virtual extension line 7 to the left and has a step. No shape. On the other hand, in the notch 6 on the right side, the tear in the other film 10 has a shape having a step toward the upper side, whereas the tear in the one film 10 propagates on the virtual extension line 7 to the right. The shape does not have. Therefore, on both the left and right sides of the package 1, a step is formed between each break line formed by tearing each of the two front and back films 10.

  Thus, even with the configuration of the packaging body 1 according to the first modified example, a step can be reliably formed between each break line formed by tearing each of the two front and back films 10, respectively. This makes it easier to grasp the knob. And with the configuration in which the angles (α2, α3) formed by each of the cuts 6 with respect to the virtual extension line 7 are obtuse angles of 105 degrees to 155 degrees, between the respective fracture lines in the front and back two films 10 A step that can be easily grasped as a knob can be formed.

  FIG. 3 is a plan view showing a second modification of the package 1. The packaging body 1 according to the second modification has a notch 6 having a position different from that of the configuration of the first modification described above. In FIG. 3, a notch 6 corresponding to a first notch possessed by one film 10 (front side film), a notch 6 corresponding to a second notch possessed by the other film 10 (back side film), and a virtual extension line The package 1 with which the intersection with 7 corresponds is illustrated. Other features are the same as those in the above-described embodiment.

  In the region of the unsealed portion 5 in one film 10 of the package 1, a notch 6 is formed in the direction (left direction) in which the virtual extension line 7 extends from one end side (here, the left side) of the opening 8. The second seal portion 4 is provided so as to extend in the upward direction toward the second seal portion 4. FIG. 3 shows an example in which the angle α4 formed by the virtual extension line 7 and the notch 6 is 120 degrees. On the other hand, the packaging body 1 according to the second modification further has a notch 6 that intersects with an inclination angle with respect to the direction in which the virtual extension line 7 extends from one end side of the opening 8 in the other film 10. . More specifically, in the region of the unsealed portion 5 in the other film 10 of the package 1, with respect to the direction (left direction) in which the virtual extension line 7 extends from one end side (here, the left side) of the opening 8, The notch 6 is provided so as to extend in the upward direction toward the second seal portion 4. FIG. 3 shows an example in which the angle α5 formed by the virtual extension line 7 and the cut 6 is 140 degrees.

  In the notch 6 of one film 10, the tear of one film 10 is directed upward, whereas in the notch 6 of the other film 10, the tear of the other film 10 is directed upward. However, since the notch 6 on the one film 10 side and the notch 6 on the other film 10 side have different angles α4 and α5 formed by the virtual extension line 7, each film 10 is torn. The shape of the break line formed is different. Therefore, a step is formed between the respective break lines formed by tearing the two front and back films 10.

  Thus, even with the configuration of the packaging body 1 according to the second modified example, a step can be reliably formed between each rupture line formed by tearing each of the two front and back films 10, respectively. This makes it easier to grasp the knob. The angles formed by the cuts 6 with respect to the virtual extension line 7 (α4, α5) are obtuse angles of 105 degrees to 155 degrees, and the angles formed by the angles (α4, α5) are different from each other. A step that can be easily grasped as a knob can be formed between the broken lines in the two films 10.

  In addition, although illustration is abbreviate | omitted, the package 1 may be the structure which the notch 6 which one film 10 has, and the notch 6 which the other film 10 has, and the intersection of the virtual extension line 7 do not correspond, In that case, the angles (α4, α5) formed by the cuts 6 with respect to the virtual extension line 7 may be the same.

  FIG. 4 is a plan view showing a third modification of the package 1. The configuration of the package 1 according to the third modification is different from the other embodiments in that the opening 8a is in contact with the cut 6. As illustrated in FIG. 4, the opening 8 a of the package 1 according to the third modification is provided in contact with the left cut 6. As described above, the opening 8 a may be provided so as to be in contact with the notch 6. Furthermore, the opening 8a may be provided so as to contact not only the left notch 6 but also the right notch 6. However, when the opening 8a and the cut 6 are provided in contact with each other, the cut 6 is a half cut. By carrying out like this, the situation where the package 1 is opened accidentally in the state before the film 10 is torn can be prevented.

  In the packaging body 1 illustrated in FIG. 4, the two cuts 6 are in the direction in which the virtual extension lines 7 extend from both ends (left and right sides) of the opening 8 a to the outer edges (left and right ends) of the packaging body 1. , Both extend so as to cross downward toward the first seal portion 3. Thus, the notch 6 of the package 1 according to the present embodiment may be provided in the direction shown in FIG.

  Next, the film which comprises the package 1 of this embodiment is demonstrated in detail. The film 10 constituting the package 1 of the present embodiment may be in the form of a single layer film or may be in the form of a multilayer film in which a plurality of materials are laminated. For example, the film 10 may have a three-layer structure including a surface layer, a barrier layer, and a heat seal layer.

  As the surface layer, for example, a synthetic resin film is used, and in particular, a uniaxially stretched thermoplastic synthetic resin film having directionality in a uniaxial direction, or a biaxial structure having a very large orientation in other directions compared to a unidirectional direction A stretched thermoplastic synthetic resin film is used. More specifically, for example, a biaxially stretched polyethylene terephthalate (PET) film can be used as the surface layer. These stretched films are laminated so that the stretching direction and the extending direction of the virtual extension line 7 coincide with each other, thereby making it easier to tear the film 10 and further stabilizing the directionality thereof. . The surface layer is required to have strength as a base material for the film 10. The thickness of the surface layer is preferably 12 μm to 16 μm. A printed layer may be provided on the back surface of the surface layer.

  For example, a metal foil is used as the barrier layer, and among these, an aluminum (Al) foil is preferably used. The thickness of the barrier layer is preferably 7 μm to 9 μm. The surface layer and the barrier layer can be laminated by dry lamination with an adhesive such as a polyurethane adhesive. Further, the surface layer and the barrier layer may be laminated by melting and extruding a heat-fusible resin such as polyethylene instead of the adhesive, and a general lamination method can be used. In the case of the contents 100 that do not require barrier properties against oxygen, water vapor, or the like, the barrier layer may be omitted.

  The heat seal layer may be any material that is melted by heat and fused to each other so as to exhibit easy peel properties. More specifically, for example, a polyethylene (PE: PolyEthylene) film can be used as the heat seal layer. The thickness of the heat seal layer is preferably 30 μm to 40 μm. Similarly, the barrier layer and the heat seal layer can be laminated by dry lamination with an adhesive such as a polyurethane adhesive. Furthermore, the barrier layer and the heat seal layer may be laminated by melting and extruding a heat-fusible resin such as polyethylene instead of the adhesive, and a general lamination method can be used.

  In the case of a half cut formed only in a single layer (surface layer) of the multilayer film, the cut 6 is preferably formed before the film 10 is laminated. However, the half-cut notch 6 can also be formed after the film 10 is laminated. If it is after lamination | stacking of the film 10, the cut 6 of a half cut can also be formed in several layers including a surface layer. On the other hand, the cut 6 is preferably formed after the films 10 are laminated in the case of full cut. The incision 6 may be either a full cut or a half cut, as long as it is appropriately formed at a location that becomes the unsealed portion 5 after bag making, regardless of the formation method. For example, a blade provided on a roller Can be formed by pressing the film onto the film 10.

  The package 1 is made from the film 10 in which the notches 6 as described above are appropriately formed. As described above, in the present embodiment, two packaging materials are used, and the respective packaging materials are overlapped to form a bag. However, the package 1 may be formed by folding a single film 10. Adhesion of the film 10 when the package 1 is made may be a method using an adhesive. However, since, for example, a polyethylene film is used for the film 10 as a heat seal layer, the film 10 is heat-sealed (heat-sealed) after being superposed so that the heat seal layers of the film 10 face each other. Manufacturing is easy and preferable. In addition, although it is not ask | required whether the two packaging materials which comprise the package 1 are the same material, or a different material, it is better that they are the same material from the ease of manufacture.

  Next, the opening method of the package 1 which concerns on this embodiment is demonstrated in detail. FIG. 5 is a schematic view showing an example of a state in which the opening 8 is pushed in when the package 1 is opened. Here, the opening method about the package 1 in which the notch 6 of FIG. 2 was formed is shown.

  The content container 2 and the first seal 3 side of the package 1 are gripped by either hand, and the second seal 4 side is picked by the thumb and index finger of the other hand. And as FIG. 5 shows, the upper part of the opening part 8 vicinity which is an opening end of the package 1 is pushed in the direction of the arrow which points to the back | inner side. At this time, if the thumb is slid from the upper side of the package 1 and the nail is applied to the opening 8, the opening operation is facilitated. Then, when the thumb is pushed into the back side as it is, or when it is twisted up while being pushed into the back side, a tear propagates from the opening 8, and passes through the notch 6 or without passing through the notch 6. The upper region is separated from the package 1.

  FIG. 6 is a schematic view showing an example of a state after the package 1 is torn when the package 1 is opened. One film 10 (front film) is provided with a cut 6 on the left side. Therefore, the tear propagated from the left side of the opening 8 is directed upward via the notch 6. On the other hand, the tear propagated from the right side of the opening 8 is directed toward the right end of the package 1 along the above-described virtual extension line 7 to form a breaking line 9. The other film 10 (back film) is provided with a cut 6 on the right side. Therefore, the tear propagated from the right side of the opening 8 goes upward through the notch 6. On the other hand, the tear propagated from the left side of the opening 8 is directed toward the left end of the package 1 along the virtual extension line 7 to form a break line 9.

  Thus, a region 11 in which only one film 10 (front side film) is present is formed in the upper left portion of the package 1 after the upper region of the opening 8 is divided, and the other film is formed in the upper right portion. A region 12 where only 10 (back side film) exists is formed. Accordingly, when the upper left region 11 of the package 1 is picked, one film 10 (front film) can be grasped, and when the upper right region 12 of the package 1 is picked, the other film 10 (back film) is grasped. be able to.

  Thus, the one film 10 and the other film 10 can be easily grasped by drawing different trajectories with different break lines and different shapes. And even when the area | region of the unseal | sticker part 5 has adhered, the one film 10 and the other film 10 can be grasped separately separately, respectively.

  Thereafter, the first seal portion 3 is peeled off by being pulled so that the one film 10 and the other film 10 are separated in the front direction and the back direction, respectively, and are held in the content storage portion 2. The existing content 100 is taken out. At that time, since the one film 10 and the other film 10 are securely grasped, the package 1 can be easily opened. In addition, this package 1 is easy to open even for an elderly person who has some anxiety about the operation of a fine fingertip.

  As described above, according to the configuration of the packaging body 1 according to the present embodiment, a step is formed between each rupture line formed by tearing each of the two front and back films 10, and each knob is formed. The part becomes easy to grasp. On the other hand, in the state before the film 10 is torn, the situation where the package 1 is accidentally opened can be prevented. Therefore, it is possible to provide a package 1 that is excellent in the protection of the content 100, has easy opening while preventing erroneous opening, has a simple structure, and is easy to manufacture.

  In addition, the package 1 which concerns on this embodiment demonstrated above, its modification, etc. can be freely combined in the range which does not produce contradiction. For example, the opening 8 can be configured to contact the notch 6 according to any embodiment or modification as illustrated in FIG.

  As described above, in the package 1 that holds the contents 100 with the overlapped film 10, the periphery of the package 1 is sealed by the first seal portion 3 to hold the contents 100. The second seal portion 4 is located between the content storage portion 2, the second seal portion 4 that contacts at least a part of the outer edge of the package 1, the first seal portion 3, and the second seal portion 4. And an unsealed portion 5 including a virtual extension line 7 corresponding to a direction along the direction, and has an opening 8 or a notch penetrating the film 10 on the virtual extension line 7. 8 or first ends that extend in the direction of the outer edge of the package 1 from both ends of the cut, and intersect the virtual extension line 7 between the opening 8 in at least one film 10 or one end side of the cut and the outer edge. Has notch 6 and is not sealed 5, the opening 8, or cut and, a first notch 6, and tears along the imaginary extension 7 is an end, constitutes at least one of the knob portion for peeling the first seal part 3.

  And according to the structure which concerns on this embodiment, a level | step difference is made between each breaking line formed when each of the film 10 of 2 sheets of front and back is torn, and each knob part becomes easy to grasp. On the other hand, in the state before the film 10 is torn, the situation where the package 1 is accidentally opened can be prevented. Therefore, it is possible to provide a package 1 that is excellent in the protection of the content 100, has easy opening while preventing erroneous opening, has a simple structure, and is easy to manufacture.
