  Next, a method for manufacturing the package 1 will be described below with reference to FIGS.

  First, a plastic sheet 20 shown in FIG. 4 is prepared. The plastic sheet 20 is for forming the packaging case 10. The plastic sheet 20 is formed, for example, by cutting a sheet material made of the above-described resin. In the present embodiment, the plastic sheet 20 is made of, for example, a polyester resin having a thickness of about 0.2 to 0.5 mm. The plastic sheet 20 includes four side plate forming portions 21, bottom plate forming portions 22a and 22b, a cover plate forming portion 23, two inner lid forming portions 23b, a display plate forming portion 24, two locking piece forming portions 25, two A detour piece forming portion 26 and a margin forming portion 27 are provided. In addition, the broken line in this figure is a fold line provided for facilitating the fold process necessary for forming the packaging case 10, for example, a perforated process is performed, or a fine groove is formed. It is configured by being formed.

  Each of the four side plate forming portions 21 has a rectangular shape and is connected to each other in series. The four side plate forming portions 21 are portions to be the four side plates 11 of the packaging case 10. A margin forming portion 27 is connected to the side plate forming portion 21 located at the left end in the drawing. The margin forming part 27 is a part that becomes the margin 17 of the packaging case 10.

  The bottom plate forming portions 22a and 22b are connected to the lower ends in the drawing of the first and third side plate forming portions 21 from the left in the drawing, and are parts constituting the bottom plate 12 of the packaging case 10. The bottom plate forming portion 22a has a substantially square shape, and two U-shaped notches 22c are formed near the center. The bottom plate forming part 22b has a shape having a rectangular part and an insertion locking part 22d connected to the rectangular part. The insertion locking portion 22d has two tongue-like portions protruding in the left-right direction in the drawing.

  The lid plate forming portion 23 is connected to the upper end in the drawing of the side plate forming portion 21 located at the left end in the drawing, and has a substantially square portion and an insertion piece forming portion 23a connected thereto. The lid plate forming part 23 is a part that becomes the lid plate 13 of the packaging case 10. The insertion piece forming portion 23a becomes the insertion piece 13a. The two inner lid forming portions 23b are connected to the upper ends in the drawing of the second and fourth side plate forming portions 21 from the left in the drawing, and have a trapezoidal shape. The display board formation part 24 is connected to the upper end in the figure of the 3rd side board formation part 21 from the left in the figure, and is rectangular shape. In addition, the imaginary line in the drawing is described for convenience in order to represent the boundary between the display plate forming portion 24 and the side plate forming portion 21.

  The two locking piece forming portions 25 are connected to the lower ends in the drawing of the second and fourth side plate forming portions 21 from the left in the drawing via a detouring piece forming portion 26, and the two locking pieces of the packaging case 10 15 is a part. Each locking piece forming part 25 has a body forming part 25a and two blade forming parts 25b. The body forming part 25 a is a substantially rectangular shape and is a part that becomes the body part 15 a of the locking piece 15. The two blade forming portions 25b extend from the body forming portion 25a in the left-right direction in the drawing, and are portions that become the two blade portions 15b of the locking piece 15. Each blade forming part 25b has a trapezoidal shape with a portion connected to the body forming part 25a as a bottom. In this embodiment, the lower end edge in the figure of the trunk | drum formation part 25a and the two blade | wing formation parts 25b comprises the same straight line extended in the left-right direction. The two detour piece forming portions 26 connect the two locking piece forming portions 25 and the two side plate forming portions 21 and have a flat rectangular shape.

  Next, the plastic sheet 20 is sequentially bent. First, the plastic sheet 20 is bent along three folding lines between the four side plate forming portions 21, and the margin forming portion 27 and the inner surface of the side plate forming portion 21 are joined by an adhesive or heat welding. As a result, the plastic sheet 20 is bent as shown in FIG. 5 to form a square tube as a whole. The four side plate forming portions 21 become the four side plates 11. Further, the display board forming unit 24 becomes the display board 14. In addition, after this figure, the plastic sheet 20 partially bent is shown, and the packaging case 10 is not completely formed, but is referred to as the packaging case 10 for convenience of explanation.

  After the four side plates 11 are formed, the fold line between the two inner lid forming portions 23b and the two side plates 11 is bent inward. Thereby, two inner lids 13b are formed. Next, the folding line between the lid plate forming portion 23 and the insertion piece forming portion 23a and the folding line between the lid plate forming portion 23 and the side plate 11 are folded inward. And the insertion piece formation part 23a is inserted in the clearance gap between the display board 14 and the two inner lids 13b. Thereby, the lid plate forming portion 23 becomes the lid plate 13 and the insertion piece forming portion 23a becomes the insertion piece 13a.

  Next, the posture of the packaging case 10 is changed so that the cover plate 13 and the display plate 14 are positioned on the lower side in the vertical direction. As a result, as shown in FIG. 6, the lid plate 13 and the two inner lids 13 b look like a temporary bottom of the packaging case 10, and the packaging case 10 is open upward in the vertical direction. Next, a packaged item 30 that has been filled with the contents 80 is prepared. Then, the package 30 is inserted into the packaging case 10 in a posture in which the lid 31 is positioned below the main body 32 in the vertical direction. As a result, as shown in FIG. 7, the package 30 is held in the packaging case 10 in a posture in which the lid 31 is supported by the lid plate 13 and the two inner lids 13b.

  Next, the folding line between the one locking piece forming part 25 and the bypass piece forming part 26 and the folding line between the bypass piece forming part 26 and the side plate 11 are bent inward. Further, the locking piece forming portion 25 is bent so as to form an arc shape when viewed in the y direction. And the locking piece formation part 25 is inserted in the cavity part 38 of the to-be-packaged product 30 along the dashed-dotted line in a figure. Thus, the locking piece forming portion 25 becomes the locking piece 15 and the bypass piece forming portion 26 becomes the bypass piece 16. When the locking piece forming part 25 is inserted into the cavity part 38, the body forming part 25a becomes the body part 15a, and the two blade forming parts 25b extending in the direction intersecting the body forming part 25a are the two blade parts 15b. It becomes. Further, the other locking piece 15 and the detouring piece 16 are formed by performing the same bending process on the other locking piece forming portion 25 and the detouring piece forming portion 26.

  As shown in FIG. 3, in the cavity portion 38, the two blade portions 15b of the locking piece 15 are bent with respect to the trunk portion 15a along the hollow cavity portion 38 having a cylindrical shape. Resisting this bending, an elastic restoring force is applied to the two blade portions 15b so as to return to a flat state together with the body portion 15a. Due to this elastic restoring force, it is expected that the trunk portion 15 a contacts the filling portion 33 and the two blade portions 15 b contact the outer wall 35.

  Unlike such an embodiment, the bending line between the body forming portion 25a and the two blade forming portions 25b is bent prior to bending the locking piece forming portion 25 in the step shown in FIG. Thus, the body forming portion 25a may be folded so as to extend in the direction in which the two blade forming portions 25b intersect. In this bending process, as shown in FIG. 8, the two blade portions 15 b positively contact the filling portion 33 so as to sandwich the filling portion 33 of the article 30, and the trunk portion 15 a contacts the outer wall 35. Intended. As will be understood from these aspects, locking is performed depending on the material and thickness of the sheet body forming the packaging case 10, the shape and dimensions of the locking pieces 15, and the shape and dimensions of the hollow portion 38 of the packaged object 30. A specific form in which the piece 15 is brought into contact with at least one of the filling portion 33 and the outer wall 35 of the package 30 can be appropriately selected.

  Thereafter, in FIG. 7, the fold line between the bottom plate forming portion 22 a and the side plate 11 is bent, and the fold line between the bottom plate forming portion 22 b and the side plate 11 is bent. Then, the insertion locking portion 22d of the bottom plate forming portion 22b is inserted into the notch 22c of the bottom plate forming portion 22a. Thereby, the bottom plate 12 is formed. By passing through the above process, the package 1 shown in FIGS. 1-3 is completed.

  Next, the operation of the package 1 will be described.

  According to this embodiment, as shown in FIGS. 1 to 3, the locking piece 15 of the packaging case 10 is in contact with at least one of the filling portion 33 or the outer wall 35 in the hollow portion 38 of the packaged object 30. The frictional force generated thereby can prevent the package 30 from rotating or moving with respect to the packaging case 10. Further, since the locking piece 15 has entered the hollow portion 38, it hardly appears on the exterior of the package 1. Furthermore, it is not necessary to provide a gap between the side plate 11 of the packaging case 10 and the outer wall 35 of the packaged object 30 in order to lock the locking piece 15 to the packaged object 30. Therefore, it is possible to appropriately maintain the posture of the package 30 within the packaging case 10 without impairing the appearance of the package 1.

  In particular, when the package 30 is a cosmetic container or the like, a product name or a design pattern is printed on the surface of the package 30. For example, the product name is intended to be located on the front side of the packaging body 1 opposite to the display board 14 in the y direction. According to the package 1 of the present embodiment, when the package 30 is inserted into the packaging case 10, the rotation of the package 30 is suppressed by the locking piece 15, and the product name is prevented from being deviated from the front. it can. When the packaged item 30 is a cosmetic container, since the appearance of the package 1 is regarded as important in addition to this, such a configuration is suitable.

  Since the locking piece 15 has the trunk portion 15a and the two blade portions 15b, the locking piece 15 can be appropriately deformed along the cylindrical cavity 38 as shown in FIG. In addition, when only the trunk portion 15a is connected to the side plate 11 via the bypass piece 16, the locking piece 15 is bent with respect to the side plate 11 or the bypass piece 16 while making the locking piece 15 a relatively wide portion. It is possible to prevent an excessive force from being required. Since the package 30 has a cylindrical shape, the hollow portion 38 has a cylindrical shape. The hollow portion 38 having a cylindrical shape is convenient for preventing the two blade portions 15b from being caught in the hollow portion 38 and the like.

  By supporting the locking piece 15 by the side plate 11, it is easy to make the locking piece 15 easy to insert into the cavity 38 from below in the z direction, and to securely support the locking piece 15. it can. By connecting the locking piece 15 to the side plate 11 via the bypass piece 16, it is possible to avoid the locking piece 15 from being deformed into an unintended shape in order to bypass the outer wall 35 of the package 30. it can.

  By arranging the two side plates 11 to face each other in the x direction across the package 30, the two locking pieces 15 supported by these side plates 11 enter the cavity 38 of the package 30. The to-be-packaged object 30 can be held more reliably.

  FIG. 9 shows a modification of the package 1. This modification is realized by changing a part of the bending process for the plastic sheet 20 shown in FIG. In the bending step for realizing this modification, the two blade forming portions 25b are bent about 180 ° with respect to the trunk forming portion 25a with respect to each locking piece forming portion 25. Thereby, the two blade forming portions 25b are folded over the body forming portion 25a. Then, the locking piece forming portion 25 in this state is inserted into the cavity portion 38. Then, the elastic restoring force which tries to return to the expanded state acts on the two blade portions 15b. Thereby, as shown in FIG. 9, it will be in the aspect which one side of the two blade | wing parts 15b contacts the filling part 33 in the attitude | position pressed by the other blade | wing part 15b. Further, due to the reaction force, the trunk portion 15 a contacts the outer wall 35. Even with such a modification, it is possible to appropriately maintain the posture of the package 30 within the packaging case 10 without impairing the appearance of the package 1. In order to appropriately fold the two blade portions 15b, the length of the blade forming portion 25b of the plastic sheet 20 may be slightly shortened as compared with the case where the embodiment shown in FIG. 3 is realized. preferable.

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

  Providing the two locking pieces 15 is effective for more reliable holding of the article 30 to be packaged, but the present invention is not limited to this, and may be configured to include only one locking piece 15. . Or the structure provided with the three or more latching pieces 15 may be sufficient. The configuration including the body portion 15 a and the two blade portions 15 b is an example of a specific configuration of the locking piece 15, and the specific configuration of the locking piece 15 adopts various configurations in view of holding the article to be packaged 30. it can. The locking piece 15 is not limited to the one supported by the side plate 11, and may be configured to be supported by a portion other than the side plate 11 such as the bottom plate 12. Although the structure provided with the four side plates 11 is suitable for reliably packaging the article 30 to be packaged, for example, by providing only the three or less side plates 11, either direction is open. Also good. Even with such a configuration, the locking piece 15 can be expected to have a function of keeping the package 30 in the packaging case 10. Further, in the configuration in which any direction is open, the packaged item 30 appears in the appearance even in the packaging case 10 made of an opaque sheet.
