Hereinafter, embodiments of the present invention will be described with reference to the drawings, but the present invention is not limited to the following embodiments. Also, in the drawings referred to below, the same reference numerals denote similar components.

FIG. 1 is an exploded view of one embodiment of the packaging box of the present invention. , a broken line indicating a boundary between the second lid surface portion 22 and the insertion piece 22a, and a broken line indicating a boundary between the folded portion 41 and the first lid surface portion 21 are folding lines. FIG. 2 is a perspective view showing a state in which a packaging box is formed from the developed view of FIG. 1 and the first lid surface portion 21 and the second lid surface portion 22 are opened.

The packaging box of the present invention is formed of a thin sheet material, and the sheet material may be paper, a rigid synthetic resin sheet having flexibility, or the surface of the paper (outside of the packaging box) coated with a resin film. is preferably used.

As shown in FIG. 1, the packaging box of the present invention has a first side portion 11 and a second side portion 12 . The side ends of the first side portion 11 and the second side portion 12 are connected to each other. is continuous with the side end of the second side portion 12, and the paste margin portion 13 connected to the other side end of the second side portion 12 is attached to the other side end side of the first side portion 11, so that the first side portion 11 and the second side portion 12 are connected at both side ends thereof. From this state, when the first side surface portion 11 and the second side surface portion 12 are pulled apart so that their horizontal central portions protrude outward, a substantially elliptical cylindrical body having acute angles at both ends in a horizontal cross section is formed. It is formed. At this time, the lower end sides of the first side surface portion 11 and the second side surface portion 12 are appropriately bent along the dashed line portions extending upward from the lower ends of the first side surface portion 11 and the second side surface portion 12, so that the lower end side of the cylindrical body is bent. The opening can be easily formed.

Next, the paste margin portion 14 connected to the lower end of the first side surface portion 11 is attached to the center portion of the first bottom surface portion 31 on the free end side of the bottom surface portion 30 connected to the lower end of the second side surface portion 12. , the lower opening of the tubular body is closed by the bottom surface portion 30 . A cutting line 11c intermittently penetrating the sheet material 2 is formed at the boundary between the first side surface portion 11 and the paste margin portion 14, so that the paste margin portion 14 can be easily folded. Details of the bottom portion 30 will be described later.

A tubular body is formed, and in a state where the lower opening is closed with the bottom surface portion 30, the article to be packaged is accommodated in the tubular body, and the upper opening is closed. In this embodiment, a first lid surface portion 21 and a second lid surface portion 22 are provided as the lid surface portion that closes the opening, and these are overlapped to close the opening. In the present embodiment, the upper end of the first side surface portion 11 protrudes above the upper end of the second side surface portion 12 by the height of the protruding portion 11b. The folded portion 41 is connected to the first side surface portion 11 via the folded portion 41 having the same height. The connection point with the first cover surface portion 21 is the upper end of the second side surface portion 12 and is at the same height as the connection point between the second side surface portion 12 and the second cover surface portion 22. It becomes possible to overlap the second cover surface portion 22 without a gap.

FIG. 3 is a perspective view showing a state in which the folded portion 41 is folded downward from the state shown in FIG. FIG. 5A shows a plan view of such a state as seen from above.

In the present embodiment, the first lid surface portion 21 is formed in a shape that substantially closes the upper opening of the cylindrical body, and furthermore, the free end side of the first lid surface portion 21 (the connecting portion with the folded portion 41 and the (opposite side) are formed with claw portions 21a and 21b projecting from the free ends. On the other hand, on both ends of the upper end of the second side surface portion 12, convex portions 12a and 12b projecting upward from the upper end are formed, and the second cover surface portion 22 is spaced apart from the convex portions 12a and 12b by a predetermined distance. It is connected to the upper end of the second side portion 12 at the central portion where it is placed.

As shown in FIGS. 3 and 5( a ), when the cylindrical body is covered with the first lid surface portion 21 , the central portion of the free end of the first lid surface portion 21 is separated from the second side surface portion 12 and the second lid surface portion 22 . However, the claws 21a and 21b are in contact with the convex portions 12a and 12b between the connecting portion between the second side surface portion 12 and the second lid surface portion 22 and the convex portions 12a and 12b, It protrudes outward from the upper end of the second side surface portion 12 . Since the claw portions 21a and 21b are in contact with the convex portions 12a and 12b, they are locked to each other by the frictional force generated by the contact, and the first lid surface portion 21 is naturally opened even if the first lid surface portion 21 is not held down. never open.

In addition, in the absence of the claw portions 21a and 21b, when a stress is applied in a direction in which the two connecting portions of the first side surface portion 11 and the second side surface portion 12 are brought closer to each other, the free end side of the first cover surface portion 21 is It floats upward and opens easily, but if there are claws 21a and 21b, the projections 12a and 12b press the claws 21a and 21b, and the first lid surface 21 is easily opened by the frictional force. not open to

Therefore, even if the hand is released after closing the first lid surface part 21, the first lid surface part 21 does not open, and there is no need to hold down the first lid surface part 21 when the second lid surface part 22 is closed. work becomes easier.

In this embodiment, a through hole 11a is formed in the projecting portion 11b of the first side surface portion 11, and a through hole 41a is formed in the folded portion 41. When the folded portion 41 is folded downward, The through hole 41a and the through hole 11a overlap each other to form a hole through which a display hook is passed.

Further, FIG. 4 is a perspective view showing a state in which the second cover surface portion 22 is closed from the state of FIG. 3, and FIG. 5B shows a plan view of this state viewed from above.

In the present embodiment, an insertion piece 22a is formed on the free end side of the second lid surface portion 22 (the side opposite to the connecting portion with the second side surface portion 12) to connect the first lid surface portion 21 and the folded portion 41. At the boundary, an insertion portion 21c for inserting the insertion piece 22a is formed through the sheet material. In the present embodiment, the insertion portion 21c is formed in a hat-like shape protruding toward the first lid surface portion 21, and is bent at a portion corresponding to the brim of the hat. As shown in 5(a), the insertion portion 21c is opened to form an opening between the folded portion 41 and the insertion piece 22a can be easily inserted. In this embodiment, the side edges of the insertion piece 22a are formed in a substantially dogleg shape projecting outward, and the maximum distance between both sides is slightly longer than the horizontal length of the protrusion of the insertion part 21c. , the inserting piece 22a inserted into the inserting portion 21c is locked on both sides of the protruding portion of the inserting portion 21c, making it difficult to come off.

Therefore, in this embodiment, it is difficult to open the once closed first lid surface portion 21, and if it is forced to open, the insertion piece 22a is deformed or torn off, so that it cannot be returned to the original packaging state.

Furthermore, in the present embodiment, in order to facilitate unsealing when taking out the packaged item, one of the side ends where the first side surface portion 11 and the second side surface portion 12 are connected is connected to the first side surface portion 11 and the second side surface portion 12. It is preferable to intermittently form cut lines penetrating the sheet material at the boundary with the second side surface portion 12 . In the present invention, since the protrusions 12a and 12b are formed on both ends of the upper end of the second side surface portion 12, if the protrusions on the side where the perforation lines are formed are used as knobs, the protrusions can be pinched with fingers and pulled. The sheet material can be easily cut open along the line and the tubular body can be unsealed.

In this embodiment, a perforation line 12d that intermittently penetrates the sheet material is formed at the boundary between the second side surface portion 12 and the paste margin portion 13, and the upper end of the paste margin portion 13 is formed with a convex portion 12b It is set lower than Therefore, since the convex portion 12b protrudes above the perforation line 12d, it is easy to pick and pull with fingers.

In addition, a cut line may be provided on the boundary side between the first side surface portion 11 and the second side surface portion 12 on the side of the convex portion 12a in FIG. The boundary between the convex portion 12a and the first side surface portion 11 can be cut to a height equal to the upper end of the second side surface portion 12 (the connection point between the second cover surface portion 22 and the second side surface portion 12). preferable.

Furthermore, in the present embodiment, in addition to the perforation line 12d, intermittent By forming perforation lines 12c and 12e penetrating the sheet material in advance, the sheet material is cut open along the perforation lines 12c and 12e following the perforation line 12d to easily unseal the package and to be packaged. can take things out. In the present embodiment, the perforation lines 12c, 12d, and 12e are configured so that one side of a substantially doglegged or substantially Y shape is arranged linearly with a predetermined gap therebetween, but the shape is not limited to such a shape. It doesn't matter if it's a perforation instead of something.

In addition, in the packaging box of the present invention, the shape of the opening and the lid portion above the cylindrical body is not limited to the above-described embodiment, and any shape can be applied as long as it can enclose the object to be packaged. It is possible to

Next, the configuration of the bottom portion 30 of the packaging box of the present invention will be described with reference to FIGS. 1, 6 and 7. FIG. FIG. 6(a) is a perspective view of the bottom portion 30 closing the lower opening of the tubular body of the package shown in FIG. 1, and FIG. It is a perspective view, and for the sake of convenience, illustration of members other than the bottom surface portion 30 is omitted. 7(a) corresponds to the AA' portion in FIG. 6(a), and FIG. 7(b) corresponds to the BB' portion in FIG. 6(b), respectively. 1 is a schematic partial cross-sectional view in the vertical direction of FIG.

The packaging box of the present invention is a packaging box suitable for items to be packaged, such as mascara, lip balm, and lipstick, which are cylindrical, cylindric, or polygonal. In the present invention, as shown in FIGS. 1 and 7, the bottom surface portion 30 includes a first bottom surface portion 31 positioned on the side of the first side surface portion 11 while closing the opening of the cylindrical body, and a second side surface portion a second bottom surface portion 32 located on the side of the portion 12, the first bottom surface portion 31 having a lower end connected to the lower end of the first side surface portion 11; connected to The upper end of the first bottom surface portion 31 and the upper end of the second bottom surface portion 32 are connected to each other, and as shown in FIG. 7A, the first side surface portion 11 and the second side surface portion 12 face each other. It presents a substantially inverted V shape in a vertical cross-section in the direction.

Further, in FIG. 1, broken lines in the bottom portion 30 are bending lines, and part of the bending lines are formed with cutting lines 34 intermittently penetrating the sheet material so as to facilitate bending. there is In addition, since the perforation line 12e is formed at the boundary between the second side surface portion 12 and the second bottom surface portion 32, bending at the boundary is facilitated. The perforation line 12e may be obtained by intermittently cutting the sheet material, or may be a perforated line or a half cut.

Furthermore, in the present invention, as shown in FIG. The outer circumference of the side has a shape corresponding to the side surface of the item to be packaged. On the second bottom surface portion 32 side, the distance between both sides is equal to or greater than the width of the bottom of the item to be packaged in the horizontal direction, and the outer periphery of the lower end side is the item to be packaged. It has a shape corresponding to the shape of the bottom surface of the object.

This embodiment is for a case where an item to be packaged has a cylindrical shape with a flat bottom surface. The outer circumference 33c on the lower end side of the through hole 33 on the second bottom surface portion 32 side is a linear shape corresponding to the bottom surface of the item to be packaged, and the length of the outer circumference 33c is the maximum length of the bottom surface of the item to be packaged. It is formed to be larger than the diameter.

Since the through-hole 33 having the above configuration is provided in the central portion of the bottom surface portion 30, when the packaging box of the present invention accommodates the object 51 to be packaged, it is shown in FIGS. 6(b) and 7(b). As shown, the bottom portion of the item to be packaged 51 rests on the outer periphery 33c of the through hole 33 on the lower end side on the second bottom surface portion 32 side. In addition, the central portion of the outer circumference 33 a of the through hole 33 on the side of the first bottom portion 31 is in contact with the side surface of the package 51 . In the packaging box of the present invention, since the first side surface portion 11 and the second side surface portion 12 are curved, stress acts in the direction of approaching each other due to the restoring force that tends to return to the flat plate shape. That is, the first bottom surface portion 31 and the second side surface portion 12 are in pressure contact with the item 51 to be packaged and hold the item 51 to be packaged. Furthermore, since the lower end of the item to be packaged 51 is loosely inserted into the through-hole 33 on the second bottom surface portion 32 side, the item to be packaged 51 can move toward the side ends of the first side surface portion 11 and the second side surface portion 12. movement is restricted. Therefore, movement of the object to be packaged 51 within the packaging box is prevented. In addition, when the packaging box is opened, since the lower end side of the article 51 to be packaged is held, there is no danger of it jumping out of the packaging box.

In the present embodiment, since the through hole 33 has a tapered shape in which the distance between the two sides 33b, 33b on the side of the second bottom surface portion 32 decreases downward, the object 51 can be easily accommodated.

In addition, the distance L from the lowest end of the outer circumference of the through hole 33 in the horizontal direction on the first bottom surface portion 31 side to the lowest end on the second bottom surface portion 32 side shown in FIG. It is desirable to make it shorter than the minimum width in the horizontal direction of the bottom of the package 51 so that it does not drop out through the hole 33 . The position of the bottom of the item to be packaged 51 in the packaging box is determined by the height of the lowest end of the outer circumference of the through-hole 33 on the side of the second bottom surface 32 , and the connection point between the second bottom surface 32 and the second side surface 12 . The lower the height T2 from the bottom to the lowermost end, the lower the packaging object 51 is accommodated. The lower the height T3 to the lowermost end of the two bottom surface portion 32, the easier it is to accommodate the items 51 to be packaged. In addition, the higher the height T1 from the connection point between the first bottom surface portion 31 and the first side surface portion 11 to the lowermost end of the through hole 33 on the first bottom surface portion 31 side, the more the object 51 can be packaged on the second side surface. It is housed on the part 12 side. When T1<T2, the outer circumference 33a of the first bottom surface portion 31 of the through-hole 33 is unlikely to act to push the object 51 along the side surface of the object 51 toward the second side surface portion 12. Therefore, preferably T1≧T2, and more preferably T1>T2.

The height of the area for accommodating the item to be packaged 51, that is, in the present embodiment, the height from the outer periphery 33c of the through-hole 33 on the side of the second bottom surface portion 32 to the back surface of the first lid surface portion 21 is the size of the item to be packaged. 51, but in this embodiment, even if there is a gap between the upper end of the item to be packaged 51 and the first lid surface portion 21, the lower end of the item to be packaged 51 is Being held prevents the object to be packaged 51 from moving within the packaging box.

In the present embodiment, the outer periphery 33a of the through-hole 33 on the side of the first bottom surface portion 31 has an arc shape corresponding to the side surface of the item 51 to be packaged. The arcuate or elliptical shape with a radius of curvature facilitates the accommodation of the package 51 . When the object to be packaged 51 has a polygonal columnar shape, the object 51 can be easily accommodated by making the shape corresponding to the outer peripheral shape in the horizontal cross-section.

In addition, in the present embodiment, since the bottom surface of the item to be packaged 51 is planar, the outer circumference 33c of the through-hole 33 on the lower end side on the second bottom surface portion 32 side is linear. It is not limited to such a shape. When the bottom surface of the item to be packaged 51 has a shape that protrudes outward, the bottom surface may have a shape corresponding to that shape or a slightly larger similar shape. When the bottom surface of the item to be packaged 51 has an outwardly convex curved surface, the outer circumference 33c may be formed in an arc shape or an elliptical arc shape having a radius of curvature equal to or greater than the radius of curvature of the curved surface.

In this embodiment, the distance between the two sides 33b, 33b at the lowest end of the two sides 33b, 33b is the minimum distance between the two sides 33b, 33b, and is the length of the outer circumference 33c on the lower end side. The minimum distance is preferably equal to or slightly longer than the minimum width of the bottom of the package 51 in order to prevent the package 51 from moving.

In the above embodiment, the bottom surface portion 30 is connected to the second side surface portion 12 by attaching the margin portion 14 connected to the lower end of the first side surface portion 11 to the first bottom surface portion 31. The invention is not limited to such a form, and the margin portion 14 may be provided on the second side surface portion 12 side.

In the above embodiment, the side to which the folded portion 41 is connected is described as the first side portion, and the side facing the first side portion is the second side portion. The bottom surface portion 30 may be configured in the opposite direction to that of the above-described embodiment, with the side to which 41 is connected as the second side surface portion and the side facing the second side surface portion as the first side surface portion.
