At this time, the package 3 is positioned by the misalignment prevention piece 15 and the positioning piece 17, and unintended misalignment is prevented.

  Next, the front piece material 101 </ b> A and the rear piece material 102 </ b> A and the plurality of articles 3 are covered with the film 2. The film 2 has a size capable of forming a plurality of skin pack packages A1. In addition, it is preferable that the film 2 is previously heated to a temperature at which the subsequent degassing step can be appropriately performed by a heating device (not shown). More specifically, the temperature of the film 2 is set to such an extent that the film 2 is softened so as to quickly follow the shape of the article 3 to be packaged by the deaeration process and is so-called drawdown. Moreover, when it is not preferable that the package 3 is exposed to a high temperature, the temperature of the film 2 is set in consideration of the heat resistance characteristics of the package 3.

  Prior to the step of covering the front piece material 101A and the rear piece material 102A and the plurality of articles to be packaged 3 with the film 2, and further the step of placing the plurality of articles to be packaged 3, the front piece material 101A and the rear piece material 102A. Is preferably placed on a degassing table (not shown). This deaeration table is used in a deaeration process to be described later, and is composed of, for example, a metal plate in which a plurality of deaeration holes opened on the upper surface are formed. These deaeration holes are connected to a suction source. The degassing table is not particularly limited as long as it can suck air on the mounting surface. For example, a block or plate made of metal or the like, or a porous material such as ceramic. Or a combination thereof.

  Next, the suction source exerts a suction force, and suction is performed from a plurality of deaeration holes of the deaeration table. The front piece material 101A and the rear piece material 102A have through portions formed by the above-described cutting process. These penetrating portions serve as a path for guiding the air between the front piece material 101A and the rear piece material 102A and the film 2 to the plurality of deaeration holes of the deaeration table. In the present embodiment, the cardboard constituting the front piece material 101A and the rear piece material 102A itself has a large number of very fine holes. Accordingly, the air between the front piece material 101A and the rear piece material 102A and the film 2 is deaerated through the substantially whole surface of the front piece material 101A and the rear piece material 102A to the plurality of deaeration holes of the deaeration table. . Thereby, the film 2 is brought into close contact with the front piece material 101A and the back piece material 102A and the plurality of articles 3 to be packaged, as shown in FIG.

  In the present embodiment, a heat-sensitive adhesive is applied in advance to one side of each of the front piece material 101A and the rear piece material 102A. This heat-sensitive adhesive exhibits an appropriate adhesive force when the heat of the film 2 is transmitted. For this reason, the film 2 is adhere | attached on the part exposed from the some to-be-packaged goods 3 among 101 A of front piece materials. Thereby, the first region 111 described above is formed. Further, the film 2 is bonded to a portion of the rear piece material 102A exposed from the plurality of front piece materials 101A. Thereby, the second region 112 described above is formed. Note that air is blown onto the film 2 immediately after the degassing by the degassing table is completed for the purpose of strengthening the adhesion with the above-described heat-sensitive adhesive and quickly curing the film 2 at room temperature. May be attached. Thereby, the film 2 can be cooled more rapidly.

  After finishing the deaeration process, the front piece material 101A, the rear piece material 102A, and the film 2 are cut along a cutting line CL indicated by a solid line in FIG. Thereby, an intermediate product capable of forming a plurality of skin pack packages A1 shown in FIGS. 9 and 10 is obtained. In order to form the skin pack package A1 from this intermediate product, first, the back plate portion 12 is separated from the front piece 101 by bending the rear piece 102 at the fold line 121 so as to be a valley fold. In addition, the front piece 101 is folded so as to be folded in the folding line 130a, and the rear piece 102 is folded so as to be folded in the folding line 130b. The fold lines 130a and 130b are collectively formed by the cutting described with reference to FIG. Thereby, as shown in FIG. 11, the lower ends of the main plate portion 11 and the back plate portion 12 are separated from each other. The fold line 130b also serves as a planned cutting line 136 for opening the skin pack package A1. The planned cutting line 136 crosses the bottom plate portion 13 in the width direction. The planned cutting line 136 is constituted by a short cutting line or a perforation. Next, the rear piece 102 is bent at the fold line 134 so as to be a valley fold. Then, the two engaging convex portions 133 shown in FIGS. 9 and 10 are engaged with the engaging portion 125 of the back plate portion 12 as shown in FIG. Thereby, skin pack package A1 shown in FIGS. 1-5 is obtained.

  In order to open the skin pack package A1 and take out the article 3 to be packaged, for example, the rear piece 102 is cut along the planned cutting line 136 shown in FIGS. Thereby, the back board part 12 and the baseplate part 13 are parted. When the back plate 12 is lifted by holding the lower end of the back plate 12, the back surface of the main plate 11 (front piece 101) and the single side of the back plate 12 (rear piece 102) facing each other can be visually recognized. . It is preferable that notes or the like about the package 3 are printed on either or both of these areas as described above. Thereby, the purchaser can recognize the precautions to be understood before taking out the package 3. Next, in FIG. 5, the vicinity of the lower end of the article 3 is pushed from the left to the right in the figure. Thereby, the cutting of the front piece 101 is started from the hole as the formation mark of the misalignment prevention piece 15 provided in the front piece 101, and the cutting of the front piece 101 proceeds along the planned opening line 16 shown in FIG. . As a result, the article 3 can be taken out.

  Next, the operation of the skin pack package A1 will be described.

  According to this embodiment, as shown in FIGS. 1 and 5, a three-dimensional structure is realized by the main plate portion 11, the back plate portion 12, and the bottom plate portion 13. Thereby, for example, the skin pack package A1 can be erected so that the back plate portion 12 is positioned vertically downward. Therefore, more various display forms can be realized. Further, the bottom plate portion 13 including the front piece 101 and the rear piece 102 is relatively easy to improve the strength. This is suitable for stably displaying the skin pack package A1 in an upright posture. Or there exists an advantage that the front piece 101 and the back piece 102 can be comprised with a relatively thin material. Moreover, in the baseplate part 13 which consists of the front piece 101 and the back piece 102, the opening start point at the time of opening the skin pack package A1 about the boundary of the front piece 101 and the back piece 102, the boundary of these and the film 2, etc. Can be used as In particular, since a finger or the like can be inserted into the space surrounded by the main plate portion 11, the back plate portion 12, and the bottom plate portion 13, the opening operation can be facilitated.

  The bottom plate portion 13 is provided with a first region 131 and a second region 132, and the film 2 is joined across the front piece 101 and the rear piece 102. Thereby, it is possible to join the front piece 101 and the rear piece 102 through the film 2, and there is no need for troubles such as applying a dedicated adhesive for joining the front piece 101 and the rear piece 102. is there. Moreover, in this embodiment, the adhesive layer mentioned above is provided in the whole one side of each of the front piece 101 and the back piece 102. FIG. Thereby, in the 1st area | region 131 and the 2nd area | region 132, the film 2, the front piece 101, and the back piece 102 can be adhere | attached more firmly. In particular, in the present embodiment, as shown in FIG. 4, the full width portion 131a and the narrow width portion 131b are configured. By providing the narrow portion 131b, the second region 132 can be appropriately secured and the strength of the bottom plate portion 13 in the entire length in the y direction can be improved.

  By engaging the engagement convex portion 133 of the bottom plate portion 13 with the engagement portion 125 of the back plate portion 12, the three-dimensional structure of the main plate portion 11, the back plate portion 12 and the bottom plate portion 13 is more reliably and stably achieved. Can be maintained. Further, the bottom plate portion 13 appears on the back plate portion 12 side, and when the skin pack package A1 is observed from the front, the engagement convex portion 133 is hardly visually recognized. This has the advantage that the skin pack package A1 can be displayed with a more beautifully arranged appearance.

  The leg portion 118 of the main plate portion 11 and the leg portion 128 of the back plate portion 12 are end portions of the front piece 101 and the rear piece 102, and are not bent portions. For this reason, the shape of the edge of the leg part 118 and the leg part 128 can be set to an exact straight line shape by cutting. Therefore, the skin pack package A1 can be raised more stably. Further, the bottom plate portion 13 is inevitably narrower in width in the y direction than the main plate portion 11 and the back plate portion 12 in correspondence with the provision of the leg portion 118 and the leg portion 128. However, the strength of the bottom plate portion 13 can be improved by making the central portion in the y direction of the bottom plate portion 13 relatively wide.

  The bottom plate portion 13 is provided with a planned cutting line 136. The planned cutting line 136 is easier to cut than the surrounding portion. Further, by inserting a finger into the space surrounded by the main plate portion 11, the back plate portion 12 and the bottom plate portion 13, it is easy to cut along the planned cutting line 136. With such a configuration, it is possible to guide the purchaser of the skin pack package A1 so that smooth opening can be started.

  The main plate portion 11 is provided with a first region 111 and a second region 112. A boundary 113 between the first region 111 and the second region 112 is generally likely to be a starting point from which the film 2 is peeled off. For example, when the back piece 102 is formed by bending the rear piece 102 at the folding line 121 in the manufacturing process of the skin pack package A1, an external force tends to act near the folding line 121. By providing the fold line 121 in which the action of such an external force is concerned near the lower end of the main plate portion 11 with respect to the boundary 113, it is possible to avoid the external force acting on the fold line 121 from being transmitted to the boundary 113. It is. Therefore, it is possible to prevent the film 2 from being unintentionally peeled off from the boundary 113 during the manufacturing process of the skin pack package A1, and also during conveyance and display. In addition, since the boundary 113 has a shape having the detour portion 113a, even if an external force is transmitted to the boundary 113, the external force does not work in one direction on the film 2 positioned at the boundary 113, and the detour is bypassed. Depending on the shape of the part 113a, it will act in an uneven state toward a plurality of directions. Thereby, it can prevent that peeling of the film 2 starts at a stretch in the boundary 113. FIG. Further, the rear piece 102 of the main plate portion 11 is joined to the film 2 at the top portion 112a and the two side portions 112b. In other words, the second region 112 surrounds three sides of the package 3. Thereby, it is possible to join the film 2 and the back piece 102 more reliably, and the peeling prevention effect of the film 2 can be improved.

  Since the base material 1 is constituted by the front piece 101 and the rear piece 102, for example, the back surface of the main plate portion 11 (front piece 101) and the one surface of the back plate portion 12 (rear piece 102) that face each other are taken into consideration. Can be used as a printing area. Thereby, the printing area can be expanded without increasing the size of the skin pack package A1 itself. Further, since the scheduled opening line 16 is hidden by the back plate portion 12, the packaged product 3 as a product cannot be easily taken out unless the bottom plate portion 13 is opened. Thereby, skin pack package A1 exhibits the function (tamper prevention function) which prevents unintentional opening.

  12 to 23 show a modified example and other embodiments of the present invention. In these drawings, the same or similar elements as those in the above embodiment are denoted by the same reference numerals as those in the above embodiment.

  12 and 13 show a modification of the skin pack package A1. In this modification, the configurations of the main plate portion 11 and the back plate portion 12 are mainly different from the example of the skin pack package A1 described above. On the other hand, the configuration of the bottom plate portion 13 is the same as the configuration shown in FIG.

  In this modification, as shown in FIG. 13, the width of the back plate portion 12 is narrower than the width of the main plate portion 11. The length of the fold line 121 is smaller than the x-direction dimension of the detour portion 113a of the boundary 113. The fold line 121 is located between the two end portions 113b in the x direction. That is, the fold line 121 does not overlap the two end portions 113b in the x direction.

  Two notches 117 are formed in the main plate portion 11. Each cut portion 117 is a cut extending inward from the edge in the x direction of the main plate portion 11. The cut portion 117 is a cut provided in the front piece 101 constituting the main plate portion 11, and this cut is not provided in the rear piece 102. The cut portion 117 is disposed below the both end portions 113b in the z direction. In the present example, the fold line 121 is located between the both end portions 113b and the cut portion 117 in the z direction.

  Also according to this modification, more various display forms can be realized. Moreover, as shown in FIG. 13, the fold line 121 is included in the detour portion 113a in the x direction, and does not overlap the two end portions 113b. From the viewpoint of increasing the bonding strength between the film 2 and the rear piece 102 in the second region 112, it is preferable to arrange the two end portions 113b closer to the lower end and make the two side portions 112b longer. However, if an external force is transmitted from the fold line 121 to the side portion 112b, the film 2 may be peeled off. In the present modification, the fold line 121 and the both end portions 113b do not overlap in the x direction, so that an external force is not easily transmitted from the fold line 121 to the both end portions 113b. Therefore, both end portions 113b can be arranged closer to the lower end, the bonding strength between the film 2 and the rear piece 102 can be increased, and peeling of the film 2 can be prevented.
