The convex portions 12c and 14c (see FIG. 3) are engaged with the engaging holes 22c and 24c, respectively, with the lid portion 20 fitted to the main body portion 10.

Information about the product and information about how to remove the lid 20, which will be described later, are printed on the front plate 13 of the main body 10 and the front plate 23 of the lid 20. As a result, the product as the content can be appealed, and the lid 20 can be easily removed by an adult. 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 forming the main body 10 and the blank plate 200 forming the lid 20 are formed by punching out a transparent resin sheet. As the material of the resin sheet, for example, PET (polyethylene terephthalate) or PP (polypropylene) can be used.

The blank plate 100 forming the main body 10 may be a flexible sheet-like member, and other materials such as paper can be used. 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.

Further, the blank plate 200 forming the lid portion 20 may be a sheet-like member, and other materials such as paper can be used. As in the present embodiment, when the blank plate 200 is transparent, the lock mechanism described later can be visually recognized, so that the lid portion 20 can be easily removed. On the other hand, if the blank plate 200 is opaque, the lock mechanism cannot be visually recognized, so that the child cannot easily remove the lid 20 and the 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 a glue margin piece 16 are connected in order via a folding line 90. A first protruding piece 13a is continuously provided above the front plate 13 via a folding line 90. A notch portion 15a having a substantially home base shape is formed by punching at the upper end portion of the back plate 15.

Below the front plate 13 and the back plate 15, first bottom plates 73 and 75 are continuously provided via folding lines 90, respectively. In the drawings of the first bottom plates 73 and 75, adhesive pieces 73a and 75a are continuously provided on the right side via a folding line 90 inclined by about 45 ° with respect to the bottom of the front plate 13.

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

A leaf-shaped leaf-shaped region 19b surrounded by a curved fold line 90 composed of lead ruled lines is formed between the front plate 13 and the side plate 14. A recess 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 glue margin piece 26 are sequentially provided via a folding line 90. A top plate 28 is continuously provided above the front plate 23 via a fold line 90, and an insertion piece 28a is continuously provided at the front end (upper in the drawing) of the top plate 28 via the fold line 90. A second protruding piece 23a is continuously provided below the front plate 23 via a folding line 90.

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

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

Hereinafter, a method for forming the main body 10 of the packaging container 1 will be described. In the blank plate 100 of FIG. 7, the side plate 12 is bent at the folding line 90 toward the inner surface side of the front plate 13, and the back plate 15 is bent at the folding line 90 toward the inner surface side of the side plate 14. Then, the inner surface of the glue margin piece 16 is adhered to the outer surface of the side plate 12 with a double-sided adhesive tape or the like. Further, the adhesive regions A1 and B1 are adhered by a double-sided adhesive tape or the like, and the adhesive regions A2 and B2 are adhered to form the bottom surface portion 17 of the auto bottom structure.

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

When the flat body portion 10 is pressed by fingers in the direction in which the folding lines 90 at the left and right ends approach each other, the body portion 11 is raised into a tubular 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 tubular body portion 11 is closed by the bottom surface portion 17 of the auto bottom structure. Further, the first protruding piece 13a is bent to the outside of the body portion 11. As a result, the main body portion 10 is formed.

Next, a method of forming the lid 20 of the packaging container 1 will be described. In the blank plate 200 of FIG. 8, the side plate 22 is bent toward the inner surface side of the front plate 23 by the folding line 90, and the back plate 25 is bent toward the inner surface side of the side plate 24 by the folding line 90. Then, the inner surface of the glue margin piece 26 is adhered to the outer surface of the side plate 22 with a double-sided adhesive tape or the like. As a result, as shown in FIG. 10, the lid portion 20 is formed in a flat state in which the body portion 21 is flatly crushed. Like the main body 10, the lid 20 is transported and stored in a flat state (folded body) having a small volume, and is discarded after being reduced in volume.

When the flat lid portion 20 is pressed by fingers in the direction in which the folding lines 90 at the left and right ends approach each other, the body portion 21 is raised into a tubular shape. As a result, the side plates 22 and 24 are arranged substantially perpendicular to the front plate 23 and the back plate 25.

Further, the back flap 25a is bent inward to form a slit 25d (see FIG. 6). The side flaps 22a and 24a are overlapped on the back flap 25a and bent inward to form engaging 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. As a result, the top plate 28 closes the upper surface of the body portion 21. Further, the second protruding piece 23a is bent inside the body portion 21. As a result, the lid portion 20 is formed.

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

Then, the lid portion 20 is fitted on the upper portion of the main body portion 10 so that the front plate 13 and the front plate 23 face each other. As a result, the opening 11a is closed by the lid 20, and the convex portions 12c and 14c of the main body 10 engage with the engaging holes 22c and 24c of the lid 20, respectively.

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

FIG. 11 is a side sectional view showing a main part in a state where the lid portion 20 is fitted to the main body portion 10. When the lid portion 20 is fitted to the main body portion 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 by one hand of the user as shown by the arrow PS (see FIG. 1). As a result, the front plate 13 and the first protruding piece 13a are deformed so as to be convex 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. By pressing the front plate 13, the first protruding piece 13a retracts from above the second protruding piece 23a.

Next, when the lid portion 20 held by the other hand is slid in the direction of the arrow OP, the second protruding piece 23a passes in front of the first protruding piece 13a. As a result, the lid portion 20 can be removed from the main body portion 10. Further, the convex portions 12c and 14c are elastically deformed and easily escape from the engaging holes 22c and 24c. As a result, 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 protruding piece 13a project forward by the recess 19, the second protruding piece 23a can be reliably engaged with the first protruding piece 13a. As a result, children such as infants cannot easily remove the lid 20, so that accidental ingestion of the contents 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. Therefore, adults including the elderly can easily understand how to remove the lid 20. Further, even if the method of removing the lid portion 20 cannot be initially understood, it can be understood by looking at the information on the method of removing the lid portion 20 printed on the packaging container 1.

According to the present embodiment, the lid 20 is removed when the front plate 13 (first peripheral plate) on which the first protruding piece 13a is arranged is deformed by pressing and the lid 20 is slid. Further, when the pressing of 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 protruding piece 13a and the second protruding portion 23a. As a result, it is possible to prevent a child from opening the packaging container 1 without separately providing the lid portion 20 with a movable inner cylinder as in the conventional example. Therefore, it is possible to improve the safety for children and reduce the manufacturing cost of the packaging container 1.

Further, the first protruding piece 13a is formed by folding back from the front plate 13 (first peripheral plate) on the peripheral edge of the opening 11a (first opening). Therefore, the first protruding piece 13a that protrudes in the direction away from the opening 11a can be easily realized. Similarly, the second protruding piece 23a is formed by folding back from the front plate 23 (second peripheral plate) on the peripheral edge of the opening 21a (second opening). Therefore, the second protruding piece 23a that protrudes in the direction away from the opening 21a can be easily realized.

Further, the front plate 13 has a curved portion 13k in which the ridgeline at one side end is curved inward. As a result, the front plate 13 and the first protruding piece 13a are convexly curved outward. Therefore, the first protruding piece 13a and the second protruding piece 23a can be reliably engaged with each other while the pressing of the front plate 13 is released.

Further, in a state where the lid portion 20 is fitted to the main body portion 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. As a result, as soon as the front plate 13 is pressed and the lid portion 20 is slid, the second protruding piece 23a overlaps the front of the first protruding piece 13a. At this time, the lid 20 can be removed even if the pressure on the front plate 13 is released. Therefore, the pressing time of the front plate 13 can be shortened, and the lid portion 20 can be removed more easily.

Further, convex portions 12c and 14c protruding outward from the peripheral edge of the opening 11a (first opening) are provided, and engaging holes 22c and 24c with which the convex portions 12c and 14c engage are provided in the lid portion 20. There is. As a result, the convex portions 12c and 14c slide on the inner surface of the lid portion 20 and are elastically deformed, and when they are inserted into the engaging holes 22c and 24c, the deformation is released and a clicking sound is generated. Therefore, the user can easily recognize that the lid portion 20 is securely fitted to the end position.

Further, the lid portion 20 has a top plate 28 that closes the upper surface (opposing surface of the second opening), and an insertion piece 28a is continuously provided at 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. As a result, the child cannot easily open the top plate 28, and the safety of the packaging container 1 can be further improved.

Further, the back plate 15 is provided with a notch portion 15a in which the insertion piece 28a is arranged inside with the lid portion 20 fitted to the main body portion 10. As a result, it is possible to prevent interference between the back plate 15 and the insertion piece 28a when the lid portion 20 is fitted to the main body portion 10, and the convenience of the packaging container 1 can be improved.

Further, since the lid portion 20 is made of a transparent material, the user can visually recognize the structure of the lock mechanism composed of the first protruding piece 13a and the second protruding piece 23a. Therefore, even an elderly person can easily remove the lid portion 20.

Further, if the lid portion 20 is made of an opaque material, the structure of the lock mechanism including the first protruding piece 13a and the second protruding piece 23a cannot be visually recognized. Therefore, it becomes more difficult for the child to remove the lid portion 20, and the safety of the packaging container 1 can be further improved.

<Second Embodiment>
Next, FIG. 14 shows a perspective view of the packaging container 1 of the second embodiment. For convenience of explanation, the same parts as those in the first embodiment shown in FIGS. 1 to 13 are designated by the same reference numerals. This embodiment is different from the first embodiment in that the recess 19 is omitted. Other parts are the same as those in the first embodiment.

The main body 10 of the packaging container 1 of the present embodiment is not provided with the recess 19, and the horizontal cross-sectional shape of the main body 11 of the main body 10 is rectangular.
