Description

  The present invention relates to a skin pack package in which an object to be packaged is sandwiched between a base material and a film.

  A so-called skin pack package is widely adopted as a packaging form for packaging various products. FIG. 19 shows an example of a conventional skin pack package (for example, Patent Document 1). In the skin pack package X shown in the figure, a base material 91 using, for example, a cardboard made of cardboard or the like, and an article 93 to be packaged placed on the base material 91 are covered with a film 92. . In order to improve the protection and appearance of the article to be packaged 93, the space between the base material 91 and the film 92 is generally deaerated, and the film 92 is brought into close contact with the article to be packaged 93. Further, in the skin pack package X, the base material 91 includes a front piece 911 and a rear piece 912. The front piece 911 is located on the packaged object 93 side, and supports the packaged object 93 directly, for example, by inserting the packaged article 93 into a notch. The rear piece 912 is overlapped with the front piece 911 at a position farther from the package 93 than the front piece 911. The rear piece 912 is exposed from the front piece 911 in all directions. Thereby, the film 92 is joined to both the front piece 911 and the rear piece 912.

  When the skin pack package X is manufactured, the front piece 911 is placed at a predetermined position on the rear piece 912. Thereafter, the front piece 911, the rear piece 912 and the package 93 are covered with the film 92, and the space between the front piece 911 and the rear piece 912 and the film 92 is deaerated. The front piece 911 is surrounded on all sides by the exposed portion of the rear piece 912. For this reason, there is no way to positively fix the front piece 911 until the deaeration is completed after the front piece 911 is placed. In such a case, there is a problem that the front piece 911 is displaced with respect to the rear piece 912, and the skin pack package X cannot be manufactured appropriately.

Japanese Utility Model Publication No. 52-165893

  The present invention has been conceived under the circumstances described above, and an object thereof is to provide a skin pack package that can be appropriately manufactured while suppressing peeling of the film.

  A skin pack package provided by the present invention includes a base material, a film covering the base material, and an object to be packaged interposed between the base material and the film, and the base material and the film A skin pack package that is degassed with the base material having a front piece positioned closest to the package object and a rear piece furthest away from the package object, It is constituted by a part of each of the front piece and the rear piece, and has a main plate portion that supports the package, and the main plate portion is a first region where the front piece and the film are joined. And a second region to which the rear piece and the film are joined, and a boundary between the first region and the second region is a non-linear shape, and the first region and the second region Intersects the first direction in which the regions line up In two directions it has reached the both ends of the main plate portion, and characterized in that.

  In a preferred embodiment of the present invention, the boundary between the first region and the second region has a detour part that detours toward the second region in the first direction.

  In a preferred embodiment of the present invention, the entire package is surrounded by the first region.

  In preferable embodiment of this invention, the said to-be packaged object has a part which overlaps with the said detour part in said 1st direction.

  In a preferred embodiment of the present invention, the base material has one end fixed to the main plate portion on the side opposite to the packaged object, and the other end separated from the main plate portion, and It has a back plate part constituted by a part of the rear piece, and the folding line that is a boundary between the main plate part and the back plate part is entirely contained in the first region in plan view. Yes.

  In a preferred embodiment of the present invention, the fold line is located closer to the first region in the first direction than the boundary between the first region and the second region.

  In a preferred embodiment of the present invention, the fold line is included in the bypass portion in the second direction.

  According to the present invention, the boundary between the first region and the second region reaches both ends of the main plate portion in the second direction, so that at one side of the main plate portion in the first direction, The front piece is configured to cross on both sides in the second direction. Thereby, in the manufacturing process of the said skin pack package, the front piece material used as the material of the said front piece can be made into the shape mutually connected by the said adjacent skin pack package. For this reason, unlike the configuration shown in FIG. 19, the front piece material can be appropriately fixed in the step of covering with the film, etc., and the front piece material can be prevented from being unintentionally displaced. it can. In addition, the boundary between the first region and the second region generally tends to be a starting point from which the film peels. For example, a force that can be generated in the manufacturing process of the skin pack package and a force due to distortion of the front piece and the rear piece are likely to act. Even if the force is transmitted to the boundary because the boundary where the action of such a force is a concern is a non-linear shape, the force is aligned in one direction on the film located at the boundary. It does not act, but acts in an uneven state toward a plurality of directions according to the boundary of the non-linear shape. Thereby, it can prevent that peeling of the said film starts at a stretch in the said boundary. Therefore, the skin pack package can be appropriately produced while suppressing the peeling of the film.

  In FIG. 6, a line indicated by a solid line is a line cut by a cutting process performed on the front piece material 101 </ b> A using, for example, a mold. By this cutting process, the hatched region is cut out in FIG. By this cutting, for example, a portion to be the extension portion 111a and a portion to be the narrow width portion 131b are formed. Moreover, the position shift prevention piece 15, the opening scheduled line 16, and the positioning piece 17 are formed by a predetermined cutting line.

  In FIG. 7, a line indicated by a solid line is a line cut by a cutting process performed on the rear piece material 102 </ b> A using, for example, a mold. By this cutting process, the hatched region is cut out in FIG. A cut portion 127 is formed by this cutting. Further, a fold line 121 and a fold line 134 are formed by a predetermined cutting line. The fold line 134 is a part where the rear piece 102 is folded back in the bottom plate portion 13.

  Next, as shown in FIG. 8, the front piece material 101A and the back piece material 102A are overlapped. In this figure, for convenience of understanding, the back piece material 102A is given a light ink color. Further, the misalignment prevention piece 15 and the positioning piece 17 are raised. And the some to-be-packaged goods 3 are mounted in the predetermined location shown in figure. 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.

  Since the boundary 113 reaches both ends of the main plate portion 11 in the x direction, the main plate portion 11 crosses both sides in the x direction on one side of the main plate portion 11 in the z direction. Thus, as shown in FIGS. 6 and 8, in the manufacturing process of the skin pack package A1, the front piece material 101A as the material of the front piece 101 is connected to each other by the adjacent skin pack package A1. It can be. For this reason, unlike the configuration shown in FIG. 19, the front piece material 101A can be appropriately fixed in the process of covering with the film 2 and the like, and it is avoided that the front piece material 101A is unintentionally displaced. it can. Further, the boundary 113 between the first region 111 and the second region 112 generally tends 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. Since the boundary 113 in which the action of such an external force is a concern is a non-linear shape having the bypass portion 113a, even if the external force is transmitted to the boundary 113, the external force is applied to the film 2 located at the boundary 113. It does not work in one direction, but acts in an uneven state in a plurality of directions depending on the shape of the detour portion 113a. 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. Therefore, the skin pack package A1 can be appropriately manufactured while suppressing the peeling of the film 2.

  All of the objects to be packaged 3 are supported by the first region 111. The first region 111 may be a region where the front piece 101 and the rear piece 102 are overlapped. For this reason, the article 3 can be supported more reliably and stably. Since a part of the article to be packaged 3 is supported by the extending portion 111a, the second area 112 surrounds the article to be packaged 3 from three directions. Thereby, while preventing peeling of the film 2, it can avoid that the area | region which does not support the to-be-packaged goods 3 among the main plate parts 11 occupies an improperly large ratio. In addition, the aspect by which the to-be-packaged product 3 is supported by the main board part 11 is not limited to the aspect of this embodiment. For example, the packaging object 3 may be supported across the first region 111 and the second region bottom 112. Or the aspect supported by parts other than the extension part 111a among the 1st area | regions 111 may be sufficient.

  An external force is likely to act on the folding line 121 during the manufacturing process of the skin pack package A1, and also during conveyance and display. By positioning the folding line 121 in which the action of such an external force is a concern in the first region 111 in plan view, it is possible to avoid the external force acting on the folding line 121 from being transmitted to the boundary 113. Therefore, it is suitable for preventing the film 2 from peeling. The structure provided near the lower end of the main plate portion 11 with respect to the boundary 113 can be expected to have an effect of more reliably preventing external force from being transmitted to the boundary 113.

  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. 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.

  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 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. Moreover, it is easy to cut smoothly by putting a finger into the space surrounded by the main plate portion 11, the back plate portion 12 and the bottom plate portion 13. With such a configuration, it is possible to guide the purchaser of the skin pack package A1 so that smooth opening can be started.

  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 18 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.

  FIG. 12 shows a plurality of modified examples of the skin pack package A1. In the modification shown in FIG. 9A, the bypass portion 113a bypasses upward in the z direction, and the vicinity of the upper end thereof is slightly recessed downward. In the modification shown in FIG. 5B, the vicinity of the upper end of the detour portion 113a has a shape protruding locally upward in the z direction. In the modified example shown in FIG. 3C, one side near the upper end of the detour portion 113a has a protruding shape. In the modification shown in FIG. 4D, a constricted portion in the x direction is provided near the upper end of the detour portion 113a. As can be understood from these modifications, the detour portion 113a in the present invention has a specific shape as long as the detour portion 113a detours to the second region 112 side (upper side in the z direction) from the line segment connecting both ends of the boundary 113. Is not particularly limited. This also applies to the embodiments described below.

  Moreover, in the modified example shown to the same figure (d), the upper end part of the front piece 101 which comprises the main board part 11 is return | folded by the back piece 102 side. This is provided to facilitate peeling between the front piece 101 and the rear piece 102 constituting the main plate portion 11 or peeling between the main plate portion 11 and the film 2 when the skin pack package A1 is opened. Yes. Further, the two end portions 113b are formed in an arc shape and are continuously connected to the detour portion 113a. As described above, the both end portions 113b in the present invention are not limited to those having various shapes and having a clear boundary with respect to the detour portion 113a. This also applies to the embodiments described below.

  FIG. 13 shows a plurality of other modifications of the skin pack package A1. In the modification shown in FIGS. 4A and 4B, the boundary 113 does not have the both end portions 113b described above, but has only the detour portion 113a. In the modification shown in FIG. 5A, the bypass portion 113a has a triangular shape, and in the modification shown in FIG. 5B, the bypass portion 113a has an arc shape. As can be understood from these modified examples, the boundary 113 may be configured not to have both end portions 113b, and in these modified examples, the film 2 can be prevented from being peeled off.

  In the modification shown in FIGS. 13C and 13D, the boundary 113 does not have a clear detour portion 113a. In the modified example shown in FIG. 5C, the boundary 113 as a whole is along the x direction, and the specific shape is a triangular wave shape. In the modification shown in FIG. 4D, the boundary 113 is generally along the x direction, and the specific shape is a wavy line shape. As can be understood from these modified examples, the boundary 113 may have a configuration without the detour portion 113a, and the film 2 can be prevented from being peeled also in these modified examples.

  In the modification shown in FIGS. 13E and 13F, the boundary 113 has a shape bulging downward in the z direction as a whole. In the modification shown in FIG. 5E, the boundary 113 has a triangular shape that bulges downward. In the modification shown in FIG. 5F, the boundary 113 has an arc shape protruding downward. Also by these modified examples, the peeling prevention effect of the film 2 can be exhibited. The modifications shown in FIGS. 13A to 13F can be appropriately applied to the embodiments described below.

  14 and 15 show a skin pack package according to the second embodiment of the present invention. The skin pack package A2 of the present embodiment is mainly different from the example of the skin pack package A1 described above in the configuration of the main plate portion 11 and the back plate portion 12. On the other hand, the configuration of the bottom plate portion 13 is the same as the configuration shown in FIG.

  In the present embodiment, as shown in FIG. 15, 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 dimension in the x direction of the detour portion 113a of the boundary 113, and the fold line 121 is included in the detour portion 113a in the x direction. 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 by this embodiment, skin pack packaging A2 can be manufactured appropriately, suppressing peeling of the film 2. Further, as shown in FIG. 15, 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 embodiment, since the fold line 121 and the both end portions 113b do not overlap in the x direction, it is difficult for an external force to be 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.

  16 and 17 show a skin pack package according to the third embodiment of the present invention. In the present embodiment, the folding line 121 is included in the detour portion 113a in the x direction, and is disposed at a position overlapping the detour portion 113a in the z direction. That is, the folding line 121 is positioned above the both end portions 113b in the z direction. In other words, such a configuration can be said to be a configuration in which the z-direction positions of the two end portions 113b are relatively moved downward.

  Since the fold line 121 is included in the detour portion 113a in the x direction, it is possible to prevent the external force applied to the fold line 121 from being transmitted to the first region 131. Moreover, the z direction length of the two side parts 112b of the 2nd area | region 112 can be extended by positioning the two both ends 113b below. This is preferable for increasing the bonding strength between the rear piece 102 and the film 2.

  FIG. 18 shows a skin pack package according to the fourth embodiment of the present invention. The skin pack package A4 of the present embodiment has only the main plate portion 11 and does not have the back plate portion 12 and the bottom plate portion 13 described above. The structure shown in FIG. 2, FIG. 12, FIG. 14 and FIG. 15 can be appropriately employed as the structure of the skin pack package A4 in plan view. In the present embodiment, the skin pack package A4 is not intended to be displayed in an upright posture, but the base material 1 includes the front piece 101 and the rear piece 102. In the area where the front piece 101 and the rear piece 102 are overlapped, for example, a precaution regarding the article 3 to be packaged can be printed on the front piece 101. Thereby, a purchaser can be made to recognize this precaution at the time of opening. Alternatively, it is possible to enclose a manual or the like made of a relatively thin paper material between the front piece 101 and the rear piece 102.

  In the present embodiment, the back plate portion 12 and the folding line 121 for forming the back plate portion 12 are not provided. However, each of the front piece 101 and the rear piece 102, which are separate members, is assumed to be distorted due to the temperature and humidity of the surrounding environment. When such distortion occurs, a force can act on the boundary 113. Also in the present embodiment, since the boundary 113 has the bypass portion 113a, such an effect of dispersing the force can be expected, and the film 2 can be prevented from peeling off.

  The skin pack package according to the present invention is not limited to the embodiment described above. The specific configuration of each part of the skin pack package according to the present invention can be varied in design in various ways.
