Description

  The present invention relates to a packaging container for packaging products.

  A conventional packaging container is disclosed in Patent Document 1. The packaging container includes a main body portion and a lid portion. The main body portion has an engaging portion projecting from the outer peripheral surface of one open end. The lid part consists of an outer cylinder (cap body) and an inner cylinder (inner plug). The outer cylinder has an elastically deformable convex portion on its inner surface that engages with the engaging portion. The inner cylinder is formed in a bottomed cylinder shape and is slidable in the axial direction in the outer cylinder.

  In the packaging container having the above configuration, when the lid portion is fitted to the main body portion, the engaging portion and the convex portion are engaged. When the inner cylinder is pressed in the axial direction, the engagement between the engaging portion and the convex portion is released by the sliding inner cylinder. In this state, the lid is removed from the main body by holding the outer cylinder and pulling it in the removal direction.

  If the outer cylinder is gripped and pulled without pressing the inner cylinder of the lid, the lid cannot be removed due to the engagement between the engaging portion and the convex portion. For this reason, a child cannot remove a cover part easily, the accidental ingestion of the content by a child can be prevented, and the safety | security of a packaging container can be improved.

The main body 10 has an opening 11 a on the upper surface of the body 11, and the bottom surface of the body 11 is closed by the bottom surface 17. The body 11 has a plurality of peripheral plates (first peripheral plates) including a side plate 12, a front plate 13, a side plate 14, and a back plate 15, which are successively arranged in the horizontal direction via a folding line 90 (see FIG. 7). The The side plate 12 is bonded with a glue piece 16 provided continuously to the back plate 15 so that the body 11 is formed in a cylindrical shape.

  The front plate 13 is continuously provided with a first projecting piece 13a that is folded outward at a fold line 90 (see FIG. 7) at the periphery of the opening 11a. The first protruding piece 13a protrudes from the upper end of the front plate 13 along the outer surface in a direction away from the opening 11a (downward in the figure). A cutout portion 15 a having a substantially home base shape in plan view with an upper opening is provided at the upper end portion of the back plate 15.

  A concave portion 19 that is recessed toward the inside of the body portion 11 is provided at a corner portion between the front plate 13 and the side plate 14. The concave portion 19 has a planar shape in which the upper end portion (end portion on the opening portion 11a side) and the lower end portion (end portion on the bottom surface portion 17 side) are narrower than the center portion. Thereby, the ridgeline of the side edge by the side of the recessed part 19 of the front plate 13 has the curved part 13k which curves inside. The front plate 13 is curved in a direction protruding forward by the recess 19. In addition, the upper part of the trunk | drum 11 is formed in a rectangular horizontal cross-sectional shape, and the horizontal cross-sectional shape is formed in the pentagon on the recessed part 19. FIG.

  Side flaps 12 a and 14 a are connected to the upper ends of the side plates 12 and 14 via folding lines 90, respectively. At the upper ends of the side plates 12 and 14, convex portions 12c and 14c made of cut and raised pieces by bending the side flaps 12a and 14a are provided on the periphery of the opening 11a. The convex portions 12c and 14c protrude toward the outside of the opening portion 11a.

  5 and 6 show perspective views of the lid 20 as viewed from the front side and the back side, respectively. The lid portion 20 is formed by closing the upper surface of a cylindrical body portion 21 having an opening portion 21a (second opening portion) at the lower end with a top plate 28. The lid 20 is fitted on the main body 10 through the opening 21a.

  The body 21 has a plurality of peripheral plates (second peripheral plates) made up of a side plate 22, a front plate 23, a side plate 24, and a back plate 25, which are successively arranged in the horizontal direction via a fold line 90 (see FIG. 8). The The side plate 22 is bonded with a glue piece 26 provided continuously to the back plate 25, and the body portion 21 is formed in a cylindrical shape.

  A back flap 25a (flap) is connected to the upper end of the back plate 25 via a fold line 90 (see FIG. 8). The back flap 25a is provided with a slit 25d at the boundary with the back plate 25. The slit 25d is formed by a U-shaped cut 25b (see FIG. 8) having both ends arranged on a folding line 90. Further, on the fold line 90 at the boundary between the back flap 25a and the back plate 25, a cut 25c (see FIG. 8) extending outward from both ends of the slit 25d is provided.

  The front plate 23 is continuously provided with a second projecting piece 23a that is folded back inwardly at a fold line 90 (see FIG. 8) at the periphery of the opening 21a. The second protruding piece 23a protrudes from the lower end of the front plate 23 along the inner surface in a direction away from the opening 21a (upward in the drawing).

  A top plate 28 is connected to the upper end of the front plate 23 via a folding line 90. An insertion piece 28 a to be inserted into the slit 25 d is provided at the tip of the top plate 28. The insertion piece 28a has a base portion 28c connected to the top plate 28 and a claw portion 28d protruding in the left-right direction from the base portion 28c. The insertion piece 28 a is inserted into the slit 25 d and the upper surface of the lid portion 20 is closed by the top plate 28. At this time, the claw portion 28d of the insertion piece 28a is engaged with both sides of the slit 25d so that the top plate 28 cannot be easily opened.

  Further, as shown in FIG. 2 described above, the insertion piece 28a is disposed inside the cutout portion 15a in a state in which the lid portion 20 is fitted on the main body portion 10. Thereby, interference with the insertion piece 28a and the backplate 15 of the main-body part 10 is prevented.

  Side flaps 22a and 24a are connected to the upper ends of the side plates 22 and 24 via folding lines 90, respectively. In addition, engagement holes 22c and 24c are provided at upper ends of the side plates 22 and 24, respectively, by bending and raising the side flaps 22a and 24a. With the lid portion 20 fitted on the main body portion 10, the projections 12c and 14c (see FIG. 3) engage with the engagement holes 22c and 24c, respectively.

  Information relating to the product and information relating to a method of removing the lid 20 described later are printed on the front plate 13 of the main body 10 and the front plate 23 of the lid 20. Thereby, while being able to appeal about the goods which are contents, the adult can remove the cover part 20 easily. Instead of printing, a sheet or the like on which the above information is printed may be attached to the front plate 13 and the front plate 23.

  7 and 8 show development views of the main body 10 and the lid 20, respectively. The blank plate 100 that forms the main body 10 and the blank plate 200 that forms the lid 20 are formed by punching a transparent resin sheet. For example, PET (polyethylene terephthalate) or PP (polypropylene) can be used as the material of the resin sheet.

  In addition, the blank board 100 which forms the main-body part 10 should just be a sheet-like member with flexibility, and can use other materials, such as paper. It is more desirable that the blank plate 100 is transparent as in the present embodiment because the contents stored in the main body 10 can be easily visually recognized.

  Moreover, the blank board 200 which forms the cover part 20 should just be a sheet-like member, and can use other materials, such as paper. Since the lock mechanism mentioned later can be visually recognized as the blank board 200 is transparent like this embodiment, the cover part 20 can be removed easily. On the other hand, if the blank plate 200 is opaque, the locking mechanism cannot be visually recognized, so that the child cannot easily remove the lid 20 and safety can be improved.

  In the blank plate 100, a side plate 12, a front plate 13, a side plate 14, a back plate 15, and an adhesive margin piece 16 are sequentially provided via a folding line 90. A first projecting piece 13 a is provided above the front plate 13 via a fold line 90. A notch 15a having a substantially home base shape is formed at the upper end of the back plate 15 by punching.

  Below the front plate 13 and the back plate 15, first bottom plates 73 and 75 are connected via a fold line 90, respectively. In the drawing of the first bottom plates 73 and 75, adhesive pieces 73a and 75a are connected to the right via fold lines 90 inclined by about 45 ° with respect to the bottom of the front plate 13, respectively.

  U-shaped cuts 12b and 14b having both ends arranged on a fold line 90 are provided at the upper ends of the side plates 12 and 14, respectively. Side flaps 12a and 14a are provided above the side plates 12 and 14 via folding lines 90, respectively. Second bottom plates 72 and 74 are continuously provided below the side plates 12 and 14 via folding lines 90, respectively.

  Between the front plate 13 and the side plate 14, a leaf-shaped leaf-shaped region 19b surrounded by a curved folding line 90 made of lead rules is formed. A concave portion 19 (see FIG. 1) is formed by the leaf-shaped region 19b.

  In the blank plate 200, a side plate 22, a front plate 23, a side plate 24, a back plate 25, and a paste margin piece 26 are sequentially provided via a fold line 90. A top plate 28 is connected above the front plate 23 via a fold line 90, and an insertion piece 28 a is connected to the front end (upward in the figure) of the top plate 28 via a fold line 90. A second projecting piece 23 a is continuously provided below the front plate 23 via a fold line 90.

  A back flap 25 a is continuously provided above the back plate 25 via a fold line 90. On the back flap 25a, a U-shaped cut 25b having both ends arranged on a fold line 90 is provided. Further, on the fold line 90 between the back plate 25 and the back flap 25a, a cut 25c extending outward from both ends of the cut 25b is provided.

  Side flaps 22a and 24a are provided above the side plates 22 and 24 via folding lines 90, respectively. Further, U-shaped cuts 22b and 24b having both ends arranged on a fold line 90 are formed on the side plates 22 and 24, respectively.

  Hereinafter, the formation method of the main-body part 10 of the packaging container 1 is demonstrated. In the blank plate 100 of FIG. 7, the side plate 12 is bent at the fold line 90 toward the inner surface side of the front plate 13, and the back plate 15 is bent at the fold line 90 toward the inner surface side of the side plate 14. Then, the inner surface of the adhesive margin piece 16 is bonded to the outer surface of the side plate 12 with a double-sided adhesive tape or the like. In addition, the adhesive regions A1 and B1 are bonded together with a double-sided adhesive tape or the like, and the bonded regions A2 and B2 are bonded to form the bottom portion 17 of the auto bottom structure.

  Thereby, as shown in FIG. 9, the main body 10 is formed in a flat state in which the body portion 11 in which the bottom surface portion 17 is housed is flattened. At this time, since the concave portion 19 is provided only on one side end of the front plate 13, the main body portion 10 can be easily made flat. The main body 10 is transported and stored in a flat state (folded body) with a small volume, and is reduced in volume and discarded.

  When the main body 10 in the flat state is pressed with fingers in the direction in which the fold lines 90 at the left and right ends approach each other, the body 11 is raised in a cylindrical shape. As a result, the side plates 12 and 14 are arranged substantially perpendicular to the front plate 13 and the back plate 15. At this time, the bottom surface of the cylindrical body portion 11 is closed by the bottom surface portion 17 of the auto bottom structure. Further, the first projecting piece 13 a is bent to the outside of the body portion 11. Thereby, the main-body part 10 is formed.

  Next, the formation method of the cover part 20 of the packaging container 1 is demonstrated. In the blank plate 200 of FIG. 8, the side plate 22 is bent toward the inner surface side of the front plate 23 at the fold line 90, and the back plate 25 is bent toward the inner surface side of the side plate 24 at the fold line 90. Then, the inner surface of the adhesive margin piece 26 is bonded to the outer surface of the side plate 22 with a double-sided adhesive tape or the like. Thereby, the cover part 20 is formed in the flat state by which the trunk | drum 21 was crushed flatly, as shown in FIG. Similar to the main body 10, the lid 20 is transported and stored in a flat state (folded body) with a small volume, and is reduced in volume and discarded.

  When the flat lid portion 20 is pressed with fingers in the direction in which the left and right fold lines 90 approach each other, the body portion 21 is raised in a cylindrical shape. Thereby, the side plates 22 and 24 are arranged substantially perpendicular to the front plate 23 and the back plate 25.

  The back flap 25a is bent inward to form a slit 25d (see FIG. 6). The side surface flaps 22a and 24a are overlapped on the back surface flap 25a and bent inward to form engagement holes 22c and 24c (see FIGS. 5 and 6). Next, the top plate 28 is overlapped on the side flaps 22a and 24a and bent inward, and the insertion piece 28a is inserted into the slit 25d. Thereby, the top plate 28 closes the upper surface of the trunk portion 21. Further, the second protruding piece 23 a is bent inside the trunk portion 21. Thereby, the cover part 20 is formed.

  After the main body 10 and the lid 20 are formed, the contents are stored in the body 11 through the opening 11a (see FIG. 3). Thereafter, the side flaps 12a and 14a are bent inward to form convex portions 12c and 14c.

  And the cover part 20 is fitted by the upper part of the main-body part 10 so that the front board 13 and the front board 23 may mutually oppose. Thereby, the opening part 11a is closed by the cover part 20, and the convex parts 12c and 14c of the main body part 10 engage with the engagement holes 22c and 24c of the cover part 20, respectively.

  When the main body portion 10 is inserted into the lid portion 20, the convex portions 12c and 14c slide and elastically deform on the inner surfaces of the side plates 22 and 24, and the deformation is released when inserted into the engagement holes 22c and 24c. At this time, a click sound is generated, and the user can easily recognize that the cover 20 has been securely fitted to the end position.

  FIG. 11 is a side cross-sectional view showing the main part in a state where the lid part 20 is fitted on the main body part 10. When the lid 20 is fitted on the main body 10, the first protruding piece 13a and the second protruding piece 23a do not overlap in the front-rear direction, and the lower end (tip) of the first protruding piece 13a and the second protruding piece 23a It is close to the upper end (tip).

  When taking out the contents of the packaging container 1, the front plate 13 of the main body 10 is pressed with one hand of the user as shown by an arrow PS (see FIG. 1). Thereby, the front plate 13 and the first projecting piece 13a are deformed so as to protrude toward the inside of the body portion 11. FIG. 12 shows a side sectional view of the first protruding piece 13a and the second protruding piece 23a at this time. The first projecting piece 13 a is retracted from above the second projecting piece 23 a by pressing the front plate 13.

  Next, when the lid 20 held by the other hand is slid in the direction of the arrow OP, the second projecting piece 23a passes through the front of the first projecting piece 13a. Thereby, the lid part 20 can be removed from the main body part 10. The convex portions 12c and 14c are elastically deformed and easily escape from the engagement holes 22c and 24c. Thereby, the packaging container 1 is opened and the user can take out the contents from the packaging container 1.

  When the pressing of the front plate 13 is released and the lid portion 20 is slid in the direction of the arrow OP, the lock mechanism including the first protruding piece 13a and the second protruding piece 23a functions. That is, as shown in FIG. 13, the second protruding piece 23a engages with the first protruding piece 13a, and the sliding of the lid portion 20 is restricted. At this time, since the front plate 13 and the first projecting piece 13a project forward by the recess 19, the second projecting piece 23a can be reliably engaged with the first projecting piece 13a. Thereby, since children, such as an infant, cannot remove the cover part 20 easily, the accidental ingestion etc. of a content can be prevented.

  On the other hand, the lid 20 can be removed by a simple method of pressing the front plate 13 and sliding the lid 20. For this reason, adults including elderly people can easily understand how to remove the lid 20. Moreover, even when the removal method of the cover part 20 cannot be understood initially, it can be understood by looking at the information regarding the removal method of the cover part 20 printed on the packaging container 1.

  According to the present embodiment, the lid 20 is removed when the front plate 13 (first circumferential plate) provided with the first projecting piece 13a is deformed by pressing and the lid 20 is slid. Further, when the front plate 13 is released and the lid portion 20 is slid, the sliding of the lid portion 20 is restricted by the engagement between the first projecting piece 13a and the second projecting portion 23a. Thereby, the opening of the packaging container 1 by the child can be prevented without separately providing a movable inner cylinder as in the conventional example in the lid portion 20. Therefore, the safety for children can be improved and the manufacturing cost of the packaging container 1 can be reduced.

  Moreover, the 1st protrusion piece 13a is turned up and formed on the periphery of the opening part 11a (1st opening part) from the front board 13 (1st surrounding board). For this reason, the 1st protrusion piece 13a which protrudes in the direction away from the opening part 11a is easily realizable. Similarly, the second protruding piece 23a is formed by folding back from the front plate 23 (second peripheral plate) on the periphery of the opening 21a (second opening). For this reason, the 2nd protrusion piece 23a which protrudes in the direction away from the opening part 21a is easily realizable.

  Further, the ridge line at one side end of the front plate 13 has a curved portion 13k that curves inward. Thereby, the front plate 13 and the first projecting piece 13a are curved outwardly. Therefore, the first protruding piece 13a and the second protruding piece 23a can be reliably engaged with each other in a state where the pressing of the front plate 13 is released.

  Further, in a state where the lid 20 is fitted to the main body 10, the lower end (tip) of the first protruding piece 13a and the upper end (tip) of the second protruding piece 23a are close to each other. Thus, when the front plate 13 is pressed and the lid portion 20 is slid, the second protruding piece 23a immediately overlaps the front of the first protruding piece 13a. At this time, the lid 20 can be removed even if the pressing of the front plate 13 is released. Therefore, the time for pressing the front plate 13 can be shortened, and the lid 20 can be removed more easily.

  Further, convex portions 12c and 14c projecting outward from the periphery of the opening portion 11a (first opening portion) are provided, and engagement holes 22c and 24c with which the convex portions 12c and 14c are engaged are provided in the lid portion 20. Yes. Thereby, the convex portions 12c and 14c slide on the inner surface of the lid portion 20 and elastically deform, and when inserted into the engagement holes 22c and 24c, the deformation is released and a click sound is generated. Therefore, the user can easily recognize that the lid 20 is securely fitted to the end position.

  The lid 20 has a top plate 28 that closes the upper surface (the surface facing the second opening), and an insertion piece 28 a is connected to the tip of the top plate 28. The insertion piece 28a is inserted into the slit 25d and locked on the side of the slit 25d. Thereby, a child cannot open the top plate 28 easily, and the safety | security of the packaging container 1 can be improved more.

  In addition, the back plate 15 is provided with a notch 15 a in which the insertion piece 28 a is arranged inside with the lid 20 fitted on the main body 10.
