Description

  The present invention relates to a packaging container that accommodates small items such as cosmetics, and more particularly, to a packaging container that has a simple structure and can lock and easily open an upper lid.

  Usually, a packaging container for storing small items such as cosmetics is made of a material such as paper or plastic, and is connected to an upper surface portion composed of an upper lid and a bottom surface portion composed of a lower lid, and between the upper surface portion and the bottom surface portion. As a representative example, a rectangular parallelepiped box made up of a front part, a back part and a side part provided. In addition, some conventional packaging containers provide a box with a locking function by engaging the insertion flaps of the lower lid and the upper lid with the side flaps so that the contents stored in the container do not easily jump out.

  As a conventional lock function, there is a lock mechanism shown in FIG. The packaging container 40 shown in FIG. 9 has a notch 44 formed at the end of the folding line 43 between the lower lid 41 and the lower lid insertion piece 42, and the flaps 45, 46 on the lower lid 41 side. The lower lid 41 is provided with a lock mechanism by providing the insertion portions 47 and 48 to be inserted into the cut portion 44.

  The lock mechanism shown in FIG. 9 may also be used for the upper lid as shown in FIG. The packaging container 50 shown in FIG. 10 has a notch 54 formed at the end of a folding line 53 between the upper lid 51 and the upper lid insertion piece 52, and the flaps 55, 56 on the upper lid 51 side are provided with the aforementioned cuts. Insertion parts 57 and 58 inserted into the insertion part 54 are provided. The lower lid is provided with the same locking mechanism as in FIG. Thereby, a lock mechanism is provided on both the lower lid 41 and the upper lid 51.

  Moreover, as an improved technique in such a packaging container, for example, a packaging box has been proposed that has an appropriate locking function that is easy to open and that can reliably mold the box (see Patent Document 1).

  The packaging box described in Patent Document 1 is a packaging box having a front plate, a side plate, a back plate, a lid, a side flap formed at an end of the side plate, and an insertion flap formed at an end of the lid. Then, the side flap has a locking portion, and the insertion flap has a pressing portion. The pressing portion is disposed at a portion that can be engaged with the locking portion, and includes a concave portion on the front surface side of the insertion flap and a convex portion on the back surface side of the insertion flap, and is folded between the lid portion and the insertion flap. It consists of a combination of a portion that is parallel to the line and a portion that is not parallel to the folding line.

  However, the locking mechanism shown in FIGS. 9 and 10 has a too strong locking strength, and the lid may be damaged when opened and closed several times. Moreover, the packaging box of the above-mentioned patent document 1 shows whether the pressing state of the insertion flap and the locking portion of the side flap are in the process of processing the convex portion formed on the back surface by pressing the pressing portion. In some cases, it is difficult to securely lock the upper lid. Further, since the locking state varies depending on the depth of the pressing portion, an advanced processing technique is required to form a suitable pressing portion. In conventional packaging containers as well as such packaging boxes, it has been difficult to reliably lock the upper lid with a simple structure when accommodating small articles such as cosmetics.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a packaging container that can contain small items such as cosmetics, and in particular a packaging container that can be reliably locked with a simple structure.

Hereinafter, embodiments of the packaging container of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a plan view of a developed state of a packaging container 1 according to an embodiment of the present invention. The packaging container 1 includes a pair of side surfaces that are connected to the back surface portion 2 and the front surface portion 3 facing each other, and both side surfaces of the front surface portion 3, and are connected to the sides of the back surface portion 2 and the front surface portion 3, respectively. The upper lid part 6 connected to the upper part of the parts 4 and 5 and at least one of the rear part 2 and the front part 3 and connected to the upper part of the front part 3 in the illustrated example, and the rear part 2 and the front part 3 Are connected to the lower part of at least one of them, and in the illustrated example, are connected to the lower part of the front cover 3, the lower cover part 7, the upper cover part 6 connected to the upper cover part 6, and the lower cover part 7. A lower lid insertion piece 9, a flap 10, 12 formed at the upper end of the side surface portions 4, 5, and a flap formed at the lower end portion of the side surface portions 4, 5. 11 and 13.

  An adhesive portion 14 that is attached to the inner surface of the side surface portion 4 is continuously provided on the side surface of the back surface portion 2. When the packaging container 1 shown in FIG. 1 is folded along the folding lines that divide each member, assembled, and an adhesive is applied to the bonding portion 14 to bond the bonding portion 14 to the inner surface side of the side surface portion 4, The packaging container 1 is formed in a thin rectangular box as shown in FIG. The packaging container 1 is not particularly limited as long as a general-purpose material such as paper or a plastic sheet can be used, and it is suitable for housing small items such as cosmetics.

  Here, the lower lid of the packaging container 1 is formed with notches 15 at both end portions of the connecting portion of the lower lid portion 7 and the lower lid insertion piece 9, and the insertion portions are formed in a part of the flaps 11 and 13. By forming 16, it can be locked. Such a lower lid is not premised on opening, and therefore, a known strong lock structure can be appropriately employed in addition to the illustrated lock structure.

  In a preferred embodiment of the present invention, a protrusion 20 is formed on the flaps 10 and 12 disposed on the upper lid 6 side. The protruding portion 20 is formed on the side surface (upper surface at the time of assembly) of the flaps 10 and 12 and has a semicircular shape in the illustrated example. In addition, the shape of the projection part 20 is not restricted to a semicircle shape, For example, a mountain shape may be sufficient. Further, the quantity to be formed is not particularly limited, and may be appropriately determined according to the dimensions of the packaging container 1. In any case, it is preferable that the protrusion 20 is formed only on a portion that is locked with a locking piece described later. This is for reliably locking with the locking piece. As shown in FIG. 2, the edge where the protrusion 20 is formed in the flaps 10 and 12, except for the protrusion 20, is slightly spaced from the upper end of the back surface 2, specifically, The size and shape are such that a gap equivalent to the thickness of the upper lid insertion piece 8 is formed. The protruding portion 20 can be formed only in a portion that has a shape, a size, and a shape that do not have this gap, and that engages with the locking piece. Thus, the protrusion 20 generates a force that pushes the upper lid insertion piece 8 when the upper lid insertion piece 8 is inserted. Therefore, the protrusion 20 can be reliably locked to the locking piece.

  Further, the upper lid insertion piece 8 is provided with a cut portion 30, and the cut portion 30 is used as a locking piece 31 that locks the protruding portion 20. The notch 30 is formed at a location corresponding to the position of the protrusion 20 when the packaging container 1 is assembled in a box shape and the upper lid insertion piece 8 is inserted into the box.

  The locking piece 31 is formed by cutting and pushing from below the insertion piece 8. Therefore, the locking piece 31 is formed in a state of protruding in the inner direction of the packaging container 1 (upward direction in FIG. 2). The cutting process and the pressing process can be performed in one process, and can be performed in individual processes. From the viewpoint of work efficiency, it is preferable to perform the cutting process and the pressing process in one step. The locking piece 31 is preferably formed by a U-shaped cut.

  As shown in FIG. 3, when the flap 10 is bent and disposed along the edge of the front portion 2, the protrusion 20 of the flap 10 is located in the gap between the front portion 2 and the flap 10. Further, the locking piece 31 of the upper lid insertion piece 8 protrudes to the inside of the packaging container 1 and locks with the protruding portion 20 of the flap 10 when the upper lid 6 is closed. Thereby, the upper lid of the packaging container 1 can be locked.

  Next, details of how to use the packaging container of the present invention will be described based on FIGS. 4 (a), (b), (c), (d) and (e).

  FIG. 4A is a cross-sectional view of the packaging container 1 in a state in which the upper lid portion 6 and the upper lid insertion piece 8 are developed. In this case, the locking piece 31 formed on the upper lid insertion piece 8 is projected upward.

  Next, as shown in FIG. 4B, the upper lid insertion piece 8 is bent from the folding line 17, the upper lid part 6 is further bent from the folding line 18, and the upper lid insertion piece 8 is bent into the protrusions 20 of the flaps 10 and 12. Plug it into the top.

  When the upper lid insertion piece 8 is further inserted, the locking piece 31 is pushed into the same plane as the notch 30 by the protrusion 20 as shown in FIG. In this state, as shown in FIG. 4 (d), when the upper lid portion 6 is further pushed in, the pressing of the locking piece 31 by the projection 20 is released, and the locking piece 31 is again protruded into the packaging container 1. The Since a clicking sound is made at this time, it can be confirmed that the lock state has been entered.

  When the upper cover 6 is moved in the opening direction in order to open the upper cover with the locking piece 31 protruding inside, as shown in FIG. 4 (e), a U-shape protruding into the packaging container 1 is formed. The tip of the locking piece 31 is brought into contact with the side surface of the protrusion 20 and locked. Thereby, opening of an upper cover can be locked reliably.

  As described above, according to the present invention, the protrusions 20 are formed on the flaps 10 and 12 arranged on the upper lid 6 side, and the locking pieces 31 to be locked to the protrusions 20 are formed on the upper lid insertion piece 8. By providing the cut part 30, the upper lid can be locked with a simple structure. Further, since a clicking sound is made when locked, the user can easily confirm that the locked state has been entered. Moreover, since it forms in the state protruded in the inner direction of the packaging container 1 so that the front-end | tip of the latching piece 31 faces the upper cover part 18, when the upper lid insertion piece 8 is inserted, the latching piece 31 is The protrusion 20 is securely locked. In addition, the box is not a structure that tends to break when the lid is opened like the lock structure of the lower lid, and the upper lid can be easily opened. Moreover, since the latching piece 31 is formed by cutting, when a packaging container is cut out from one raw material sheet with a punching die, a cutting part can be formed simultaneously, and the packaging container 1 is manufactured. Does not increase costs.

  Further, the lid locking mechanism in the packaging container of the present invention is not limited to the case where it is applied to the thin box-shaped packaging container 1 shown in FIGS. This locking mechanism can be applied to a rectangular parallelepiped packaging container 1A, which is a packaging container according to another embodiment of the present invention shown in the developed view of FIG. 5, and is the case of this packaging container 1A. However, the same effect can be obtained.

Further, as a lid locking mechanism in the present invention, the locking piece formed on the upper lid insertion piece 8 of a thin box or rectangular parallelepiped container is not limited to the locking piece 31 shown in FIG. The locking piece of the packaging container 1A shown in FIG. 5 is formed as a convex portion 32 that is linear and formed by pressing. The convex part 32 of FIG. 5 is formed in the state protruded in the container inner side direction (downward in the figure) by pressing, as shown to Fig.6 (a). Further, the protrusions 20 of the flaps 10 and 12 have a force that pushes the upper lid insertion piece 8 when the upper lid insertion piece 8 is inserted, like the packaging container 1 described with reference to FIG. It is set as the structure which produces. As a result, when the upper lid insertion piece 8 is pushed into the packaging container 1A, the tip of the convex portion 32 as the locking piece 32 of the upper lid insertion piece 8 comes into contact with the side surface of the projection 20 of the flaps 10 and 12. So that the opening of the upper lid can be reliably locked.

  Further, in the packaging container 1A of FIG. 5, the locking piece is a convex portion 33 in which a cut is formed by pressing shown in FIG. 6 (b), instead of the convex portion 32 shown in FIG. 6 (a). May be. In FIG.6 (b), the convex part 33 is formed in the state protruded in the state which has the notch 34 in the container inner side direction (downward in the figure). As a result, when the upper lid insertion piece 8 is pushed into the container, like the convex portion 32, the tip of the convex portion 33 comes into contact with the side surface of the protruding portion 20 and is locked, thereby reliably locking the opening of the upper lid. be able to.

  Another embodiment of the packaging container of the present invention will be described with reference to FIG. The locking piece of the packaging container 1B of the present embodiment shown in FIG. 7 includes the locking piece 31 described above with reference to FIGS. 1, 5, and 6, and convex portions 32 and 33 as locking pieces. A plurality (two in the figure) are provided from the connecting portion (folding line 17) with the upper lid portion 6 toward the tip of the upper lid insertion piece 8. The locking piece of the packaging container 1B may form, for example, two convex portions 32 in the vertical direction, may form a convex portion 33 having two cuts 34 in the vertical direction, The convex portion 32 may be formed on the lower side, the convex portion 33 may be formed on the upper side, and the convex portion 32 may be formed on the lower side, and various variations can be set. Furthermore, two or more of the combination of the U-shaped locking piece 31 and the convex portions 32 and 33 can be formed.

  Further, in particular, the locking piece 31 formed on the upper lid insertion piece 8 of the thin box-shaped or rectangular parallelepiped container, and the protrusions 32 and 33 as the locking pieces are shown in the unfolded state of the packaging container 1C in FIG. As shown in the plan view, it is preferably formed at a position d that is 3 mm to 5 mm away from the connecting portion (folding line 17) of the upper lid portion 6. If the distance from the folding line 17 is short, it may be difficult to fold the upper lid insertion piece 8 along the folding line. Moreover, by forming in this position, the locking piece 31, the convex parts 32 and 33 as a locking piece, and the projection part 20 are optimally locked, and the locked state of an upper cover can be improved.
