Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a side panel that constitutes a pair of side surfaces of a box body that face each other, and an end panel that constitutes a pair of end surfaces of the box body that face each other. The present invention relates to a packaging box that is joined to an end panel to form a rectangular tube-shaped body, and in particular, a packaging box with an exhibition function that can cut out a part of the box to display stored items that are products. .

[0002]

2. Description of the Related Art A conventional blank for a packaging box of this type is made by punching a corrugated board and forming a fold line. In this blank, a pair of side panels and end panels are alternately connected via a fold line. The upper and lower sides of the side panel and the end panel are fold lines, and the upper and lower flaps for closing the top and bottom surfaces of the box body are extended from the fold lines.

All the fold lines between the side panel and the end panel of the blank are bent in the same direction, and both end sides of the side panel and the end panel are joined to each other to form a rectangular tubular body. After that, the lower panel extending from the side panel and the end panel through the fold line is bent back and forth inward, fixed to each other, and the bottom of the box is closed. Furthermore, after storing the stored items from the upper surface of the box, bend the upper flap extending from the side panel and the end panel through the fold line inward,
Close the top of the box.

[0004] Some of such packaging boxes have an exhibition function in which a part of the box body can be cut out in order to display the stored items, which are products, at a retail store. For example, attach a cutting tape at a height slightly lower than the middle of the inside of the side panel and the end panel that are connected, and
This cutting tape is pulled to the outside of the box from two or more points, and at that position the upper part of the side panel and end panel and the upper flap are integrally removed, and the tape is placed on the bottom of the box for storage. Packaging boxes have been used that allow objects to be viewed externally. It is often found in packaging boxes, such as bottles, which store items to be stored in a single stack instead of stacking them in the packaging box.

[0005]

In the packaging box as described above, in order to display the stored items which are the products, the cutting tape is pulled outside the box body to cut the side body and the end panel. When the upper part of the and the upper flap are removed together,
The box remains only the bottom wall and the parts below the side panels and end panels that stand upright, leaving nothing above the contents. For this reason, it is not possible to put another box on it when it is displayed.

Therefore, conventionally, only the uppermost box is put in the display state as described above, and when the stored items in the uppermost box are sold out, the lower box is cut each time, and the display state is displayed. And that is being done. However, this was always troublesome because it was necessary to constantly monitor that the top boxed items were sold out.

In view of the above problems of the conventional packaging box with an exhibition function, the present invention is in a so-called exhibition state in which a part of the box body is opened so that the contents stored therein can be seen from the outside. Also, it is an object of the present invention to provide a packaging box with an exhibition function so that another box cannot be stacked on it.

[0008]

According to the present invention, in order to achieve the above-mentioned object, at least a part of the side flaps 2 and the end flaps 1 are cut and opened so that the contents a in the box can be seen. Even in such a state, at least a part of the upper inner flaps 6, 6 and the upper outer flaps 7, 7 are left so that another box body can be placed and supported thereon.

That is, in the packaging box, the end panels 1 and 1 and the side panels 2 and 2 forming a pair of opposing end surfaces of the box body forming a pair of opposite side surfaces of the box body alternate with each other through a fold line. And the end panel 1 and the side panel 2 at the end are joined together at their sides, and the upper inner flaps 6, 6 that close the upper surface of the box from the side panels 2, 2 and the end panels 1, 1 Outer flaps 7 and 7 are respectively extended, and cutting lines 11 and 11 that cut out a part thereof are formed on at least one of the side panels 2 and 2 and the end panels 1 and 1. In the present invention, in such a packaging box, when at least a part of the side panels 2 and 2 and the end panels 1 and 1 is cut off by the cutting lines 11 and 11, the upper inner flaps 6 and 6 and the upper inner flaps 6 and 6 are cut off. At least a part of the outer flaps 7, 7 remains so that another packaging box to be stacked thereon can be supported from below.

For example, the upper inner flaps 6, 6 are left when the side panels 2, 2 and at least one of the end panels 1, 1 are cut off by the cutting lines 11, 11. The upper inner flaps 6, 6 are supported by a part of the storage item a stored in the box body and hold the upper end of the storage item a. More specifically,
Both sides of the upper flap 6 are separated from the upper edge side thereof, and the upper flap 6 has a stored article holding piece 8 which is bent in a U shape at the central portion and both side portions and held by the upper flap 6, and is stored by the stored article holding piece 8. It surrounds and supports the upper end of the object a.

By doing so, the upper inner flaps 6, 6
Since the container itself is supported from below by the container a and the upper inner flaps 6, 6 support a part of the container a, the upper inner flaps 6, 6 and the container a are firmly held to each other. As a result, the side panel 2,
Even if a part of at least one of 2 and the end panels 1 and 1 is cut off, the shape of the packaging box does not collapse, and another packaging box placed on it can be stably supported from below. .

As still another form, the cutting line 1
When at least a part of at least one of the side panels 2 and 2 and the end panels 1 and 1 is cut off by 1 and 11, the corner portions 16 and 16 of the upper inner flaps 6 and 6 and the corner portions 17 of the upper and outer flaps 7 and 7, respectively. , 17 remain in the end panels 1 and 1 and the side panels 2 and 2, respectively, and the corner portions 16 and 16 and the corner portions 17 and 17 are bonded to each other.

Also in this case, when at least one of the side panels 2 and 2 and the end panels 1 and 1 is cut off by the cutting lines 11 and 11, the corner portions 16 of the upper inner flaps 6 and 6 that remain are cut off. , 16 and the corner portions 17, 17 of the upper and outer flaps 7, 7 are connected to the end panels 1 and 1 and the side panels 2 and 2, respectively, and they are adhered to each other, so that the shape of the packaging box does not collapse. , Another packaging box placed on it can be stably supported from below at its four corners.

BEST MODE FOR CARRYING OUT THE INVENTION Next, embodiments of the present invention will be described specifically and in detail with reference to the drawings.
FIG. 1 is a development view of a blank showing an embodiment of a general packaging box of the present invention. The blank of this packaging box uses a corrugated board in which a core made of a corrugated sheet made of paper is laminated with a liner. A blank before assembly is completed by punching a corrugated board as shown by a thick solid line in FIG. 1 and inserting a polygonal line as shown by a chain double-dashed line. It should be noted that the thick broken line indicates a notch. All the broken lines shown by the two-dot chain line are bent in the same direction with respect to the paper surface of FIG.

In the blank of the packaging box shown in FIG. 1, rectangular end panels 1 and 1 and side panels 2 and 2 are alternately connected via a fold line. The end panels 1, 1 and the side panels 2, 2 have the same height, and the two side panels 2,
2 and the two end panels 1, 1 have the same width, respectively, and the side panels 2, 2 and the end panels 1, 1 have different widths.
It goes without saying that the heights and widths of the side panels 2 and 2 and the end panels 1 and 1 differ depending on the use and the size of the stored items.

A joining flap 3 extends from the side of the end panel 1 at the end via a fold line, and no such joining flap extends at the side panel 2 at the end. In-bottom flaps 4 and 4 extend from the fold lines on the lower sides of the end panels 1 and 1. The length (left and right dimensions in FIG. 1) of the bottom flaps 4 and 4 is slightly narrower than the width of the end panels 1 and 1, and the height (upper and lower dimensions in FIG. 1) is equal to the end panels 1 and 1. Is about 1/2 of the width of.

Outer bottom flaps 5 and 5 extend from the fold lines on the lower sides of the side panels 2 and 2. The length of the outer flaps 5 and 5 (left and right dimensions in FIG. 1) is slightly smaller than the width of the side panels 2 and 2, and the height (upper and lower dimensions in FIG. 1) of the inner flaps 4 is Same as 4.

Upper inner flaps 6, 6 extend from the fold lines on the upper sides of the end panels 1, 1. The length of the upper inner flaps 6, 6 (left and right dimensions in FIG. 1) is slightly smaller than the width of the end panels 1, 1, and the height (upper and lower dimensions in FIG. 1) is the width of the end flaps 2. It is about 1/2.

Upper outer flaps 7, 7 extend from the fold lines on the upper sides of the side panels 2, 2. The length of the upper and outer flaps 7, 7 (left and right dimensions in FIG. 1) is slightly smaller than the width of the side panels 2, 2. The height of the outer upper flaps 7, 7 (upper and lower dimensions in FIG. 1) is the same as that of the outer upper flaps 6, 6. Intermittent cuts are made in the fold line that is the boundary between the side panels 2 and 2 and the upper outer flaps 7 and 7.

Approximately 1/4 of the inner surface of the end panels 1, 1, the side panels 2, 2 and the joining flap 3 from below the inner surface thereof
A continuous cut tape 12 is attached to the position of the height. Further, a pair of short vertical notches 14 and 14 are formed at positions on both sides of the side panels 2 and 2 so as to cut the cut tape 12. Further, in the center of the side panels 2 and 2, the cut tape 12 is also used.
One short vertical cut is made so as to cut, and horizontal short cuts are made at the upper and lower ends of this vertical cut to form finger hooks 13. Therefore, the finger-holding portion 13 has a horizontal H-shaped cut as a whole.

The side panels 2 and 2 are cuts each having a pair of short vertical cuts 14 on both sides thereof and a row of small L-shaped cuts symmetrically arranged on both sides of the cuts. Lines 11 and 11 are formed. This cutting line 11, 11
The lower left and right gaps are defined by the pair of short vertical cuts 14,
It is the same as the interval of 14, and the interval on the left and right above the cutting lines 11, 11 is wider.

A horizontal folding line is formed in the central portion near the upper side of the upper inner flap 6, and a pair of vertical folding lines are formed from both ends of this folding line to the upper side of the upper inner flap 6. A crank-shaped cutting line is inserted outside the pair of vertical folding lines, whereby a stored article holding piece 8 is formed near the upper side of the upper inner flap 6. The parts at both ends of the stored article holding piece 8 are insertion pieces 9 and 9 which are lowered one step by the crank-shaped cutting line.

Furthermore, a pair of vertical cuts are made on the upper side from the fold line of the upper inner flap 6 and the end flap 1, and short cuts are made horizontally at both ends of the cuts, whereby the insertion slit 10 is formed. 10 are formed. Therefore, the insertion slits 10 and 10 are notches having an I shape as a whole. The vertical slits of the insertion slits 10 and 10 are on an extension of the vertical fold line of the stored item holding piece 8.

A packaging box from such a blank is assembled in the following manner in the same manner as an ordinary packaging box. First, all the folding lines between the end panels 1, 1, the side panels 2, 2 and the joining flap 3 are bent in the same direction at an angle of 90 °. Further, an adhesive is applied to the outer surface of the joining flap 3, and the outer surface of the joining flap 3 is attached to the inner surface of the edge portion of the end panel 1. As a result, the side panels 2 and 2 and the end panels 1 and 1 form a rectangular tubular body.

Next, the bottom flaps 4 and 4 are bent inward at an angle of about 90 ° with the bottom surface of the box body facing upward. Further, the outer bottom flaps 5, 5 are bent inward at an angle of about 90 ° to close the bottom surface of the box body and the outer bottom flaps 5, 5
Are bonded to the inner bottom flaps 4 and 4 with a hot melt adhesive or the like, or the outer bottom flaps 5 and 5 are connected to each other with staples and the like.

Next, the box is turned over so that the upper surface side faces upward. In this state, put the required items in the box. After the contents are stored in the box, the upper inner flaps 6, 6 are bent inward at an angle of about 90 °. Further, whether the upper and outer flaps 7 and 7 are bent inward at an angle of about 90 ° to close the upper surface of the box body, and the upper and outer flaps 5 and 5 are bonded to the upper and inner flaps 6 and 6 with a hot melt adhesive or the like. Alternatively, the upper and lower flaps 7, 7 are connected to each other by staples or the like. This state is shown in FIG.

Next, in order to remove a part of the side panel 2 of the packaging box and display the stored items as products,
First, a finger is inserted from the finger-holding portion 13 of the side panel 2, one of the H-shaped cuts is picked with the finger, and the portion near the lower side of the side panel 2 is laterally cut by the cut tape 12 on the back surface. Since the cut tape 12 is cut by a pair of short vertical cuts 14 on both sides, the cut tape 1
The cutting of the side panel 2 by means of 2 stops at this one notch 14. Further, a finger is inserted again from the finger hook portion 13, the other portion cut into the H shape is picked with the finger, and the portion near the lower side of the side panel 2 is laterally cut to the opposite side by the cut tape 12 on the back surface. . Also in this case, the cutting of the side panel 2 with the cut tape 12 is stopped at the other notch 14.

Next, the central portion of the side panel 2 cut by the cut tape 12 is raised, and the side panels are shown in FIG. 1 and FIG. 2 along the cutting lines 11 formed by the cut rows on both sides thereof. The central portion 15 is cut and raised, and the central portion 15 is cut off from the intermittent cuts formed in the fold line between the upper and outer flaps 7, 7. Furthermore, the upper and lower flaps 7, 7
Up, open the upper surface of the box, and cut off the upper outer panel 7 from the intermittent cuts provided at the fold line with the side panel 2. This state is shown in FIG.

In this state, the central portion 15 (FIGS. 1 and 2) of the side panel of the packaging box is cut off and the upper and outer flaps 7, 7 are removed, so that the contents a contained therein can be seen. . Next, as shown in FIG. 4, with the remaining upper inner flaps 6, 6 raised, the stored article holding piece 8 is bent inward from the fold line at the center of the stored article holding piece 8 provided at the tip thereof. At the same time, both sides of the stored article holding piece 8 are bent inward from a pair of vertical fold lines of the stored article holding piece 8, and the insertion pieces 9 and 9 at both ends thereof are inserted into the insertion slits 10 and fixed. . In this state, the stored article holding piece 8 is fixed to the inner surface of the upper inner flap 6 in a state of being bent in a U shape.

Further, as shown in FIG. 5, the upper inner flap 6 is laid down inside the upper surface of the packaging box, and the upper inner flap 6 is placed on the stored item a in the center of the packaging box near the end panel 1. Put. In this state, the upper inner flap 6 has the storage item a.
Is supported from below and the upper end of the stored item a is held by the stored item holding piece 8. Therefore, even if another packaging box is placed on this, the upper inner flap 6 does not bend downward and the packaging box is not distorted by the mutual holding action with the stored item a. . Thereby, another packaging box placed on the upper inner flap 6 can be stably supported from below. Further, since the upper end of the stored item a is held by the stored item holding piece 8, the stored item a will not be pulled out and the support of the upper inner flap 6 will not be lost.

FIG. 6 is a development view of a blank showing another embodiment of the packaging box of the present invention. This blank is basically the same as that shown in FIG. 1, and the same portions are denoted by the same reference numerals. In this embodiment, when the upper inner panel 6, 6 and the upper outer panel 7, 7 close the upper surface of the box, triangular corner portions 16, 16, 17, 17 are provided at the corners of the upper surface of the box.
