Description

  The present invention relates to a skin pack package that sandwiches an object to be packaged between a base material and a film, and a method for manufacturing the skin pack package.

  A so-called skin pack package is widely adopted as a packaging form for packaging various products. FIG. 21 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.

  In the skin pack package X, one side (left side in the figure) of the article 3 is supported by the base material 91. For this reason, the center of gravity of the skin pack package X is located at the approximate center of the article 93 in the left-right direction in the figure. When the skin pack package X is displayed in a stand-up posture, for example, at a storefront, the edge 91c below the base material 91 is brought into contact with a display shelf or the like. Since the center of gravity of the skin pack package X is in the approximate center of the article 93, the skin pack package X is tilted to the right in the figure. In order to suppress this inclination, it is desirable to reduce the portion of the base material 91 between the edge 91c and the edge 93c below the package 3 as much as possible. However, in order to appropriately bond the film 92 to the base material 91, the end edge 91 c of the base material 91 must be separated from the end edge 93 c of the packaged object 93 to some extent. Moreover, as a malfunction regarding the gravity center position of such a skin pack package X, for example, when a suspension hole is provided in the upper portion of the base material 91 and the skin pack package X is suspended, the skin pack package X tilts. Can be mentioned.

The plurality of deaeration holes 71 are open in the plane and are appropriately connected to a suction source such as a pump (not shown). Next, the film material 20 to be the film 2 is placed on the base material 10 and the package 3. At this time, the film material 20 is heated to an appropriate temperature in order to promote appropriate deformation and to exert an adhesive force with the cardboard material.

  Next, a deaeration process is performed. This step is performed by sucking from the plurality of deaeration holes 71 by exerting the suction force of the suction source (not shown) described above. By this suction, the air between the base material 10 and the article to be packaged 3 and the film material 20 is degassed through the base material 10. Since the film material 20 is heated to a temperature at which it can be appropriately deformed, the film material 20 is remarkably stretched along the overhanging portion 12 of the base material 10 and the package 3. Thereby, as described with reference to FIGS. 1, 5, and 6, the film material 20 adheres to each part of the base material 10 and the package 3.

  Next, the base material 10 is cut. In this step, the base material 10 is cut together with the film material 20 along the rear plate parting line 110 shown in FIGS. The shape of the rear plate parting line 110 is substantially the same as that of the rear plate part 11. In the present embodiment, the side located on the x-direction ground side of the rear plate part dividing line 110 crosses the notch 150. Specifically, as shown in FIG. 9, the side of the rear plate parting line 110 is a part of the notch 150 that is a formation mark of the two connecting parts 121 and a formation mark of the front plate part 122. Cross the boundary with the part. Moreover, the said side of the rear-plate part division line 110 is set so that it may correspond with the rear side edge 11c which appeared by forming the overhang | projection part 12. FIG. By performing this cutting, the above-described skin pack package A1 is obtained.

  Next, the operation of the skin pack package A1 and its manufacturing method will be described.

  According to this embodiment, the base material 1 has the rear side edge 11c located in the rear side in the z direction, and the front side edge 12c located in the front side. The edge 3c of the package 3 is located on the top side of both the rear edge 11c and the front edge 12c in the x direction. Accordingly, as shown in FIG. 3, when the skin pack package A1 is displayed on the storefront, the skin pack package A1 is brought into contact with the display shelf by bringing the rear end edge 11c and the front end edge 12c into contact with the display shelf. Can be displayed in a standing state. Since the rear end edge 11c and the front end edge 12c are separated from each other in the z direction, for example, compared to the case where the skin pack package A1 is supported only by the rear end edge 11c, the rear end edge 11c is caused by the deviation of the center of gravity. Therefore, it is easy to avoid the skin pack package A1 becoming unstable. Moreover, since the edge 3c is located in the x direction top side rather than the rear side edge 11c, the film 2 is provided in the site | part located between the rear side edge 11c and the edge 3c among the rear-plate parts 11. FIG. It can be reliably joined. Therefore, the display posture of the skin pack package A1 can be improved while appropriately packaging the article 3 to be packaged.

In particular, in the front plate portion 122, the film 2 covers the front surface 12a and the back surface 12b via both ends in the y direction and the front side edge 12c. With such a configuration, the overhanging portion 12 is firmly fixed by the film 2 together with the article to be packaged 3, although the front end edge 12 c is separated from the rear plate portion 11 to the front side in the z direction. Therefore, when the rear end edge 11c and the front end edge 12c are brought into contact with the display shelf or the like and the skin pack package A1 is erected, the problem that the projecting portion 12 is unintentionally deformed is avoided. Can do.

  Since the front side edge 12c is positioned on the front side in the z direction with respect to the packaged item 3, the packaged item 3 is positioned between the rear side edge 11c and the front side edge 12c in the z direction. Thereby, the center of gravity of the article to be packaged 3 can be reliably supported by the rear side edge 11c and the front side edge 12c, and the skin pack package A1 can be erected in a more stable posture. Moreover, the rear side edge 11c and the front side edge 12c are located in parallel along the y direction. Thereby, when a plurality of skin pack packages A1 are displayed, it becomes easy to display them with the fronts aligned.

  In the manufacture of the skin pack package A1, when the package 3 is placed on the surface 10a, the y-direction position of the package 3 is regulated by the two notches 15 and the z-direction position is the rear plate. 11 and the front plate part 122 can be regulated. Further, by using the positioning piece 16, it is possible to regulate the position in the x direction of the article 3. Thereby, even if the packaged article 3 is, for example, a columnar shape, the position of the packaged article 3 on the base material 10 can be prevented from being unduly shifted.
