When each standing portion is bent upward from the first folding line, the previously folded second folding line is restored to its original unfolded state, thereby tensioning the flexible film member. do.

As a result, the object to be packaged is pressed against and supported by the flexible film member. This packaging tool is housed in an outer box such as a corrugated board in a state in which an object to be packaged is wrapped, and is conveyed as a packaging box.

Japanese Patent Publication No. 9-501128

However, in the packaging tool in which the object to be wrapped is wrapped, the tensioned flexible film member presses the mounting part through the object to be wrapped. As a result, the plate-shaped member may be restored to its original unfolded state from the state in which each of the standing portions is bent upward, and may be valley-folded again at the second folding line.

SUMMARY OF THE INVENTION In view of the above points, an object of the present invention is to provide a packaging tool capable of keeping an object wrapped.

In order to achieve such an object, the packaging tool of the present invention comprises a plate-shaped member on which an object to be packaged is placed, and a cylindrical member into which the plate-shaped member is inserted, and is placed at least on the plate-shaped member. and a flexible thin film member covering the packaged object, wherein the plate-shaped member has a placement portion on which the packaged object is placed on the front side, and a placement portion on which the package object is placed. A rising portion continuously provided on both sides via a first folding line capable of valley folding, and a second folding portion crossing the placing portion and the standing portion and capable of valley-folding the placing portion and the standing portion. a folding line, a tongue protruding from the standing portion to the placing portion via a first hinge portion provided on the standing portion that can be folded into a valley, and a tongue provided on the placing portion, an inserting portion open for insertion, wherein the inserting portion has a width equal to or less than the tongue so as to sandwich the inserted tongue when the standing portion is folded along the first folding line. characterized by being formed

In the packaging tool of the present invention, the plate-like member is inserted into the cylindrical thin film member so as to cover the packaging object placed on the placing portion. An object to be packaged can be sandwiched between the thin film members. At this time, by valley-folding the placing portion and both the standing portions along the second folding line, the gap becomes larger, so that it is possible to easily insert the object to be packaged.

In addition, since the standing portions are continuously provided on both sides of the placing portion via the first folding line, the first folding line and the second folding line intersect, When both of the upright portions are bent above the mounting portion along the first folding line, the previously folded second folding line is restored to its original unfolded state, and the flexible thin film member is formed. With tension, the object to be wrapped is pressed against the placing portion and supported.

At this time, the tongue piece provided on the standing portion is valley-folded by the first hinge portion and is inserted into and held by the insertion portion provided on the placing portion. As a result, the standing portion is supported in the standing posture on the placement portion via the tongue piece.

Therefore, in the packaging device of the present invention, the erected portion is restored to its original state, and the plate member is not valley-folded again along the second folding line. It can be kept wrapped.

Further, in the packaging tool of the present invention, the tongue piece and the insertion portion are configured such that the plate-like member connects the first hinge portion and both ends of the first hinge portion and protrudes toward the placement portion. It is preferable that each is formed by being surrounded by the cut lines of the .

According to this, since the tongue piece and the insertion portion can be formed from one sheet of plate-like member, it is possible to prevent an increase in dust in the manufacturing process.

Further, in the packaging tool of the present invention, the cut lines are inclined and extend from both ends of the first hinge portion toward the placement portion so that the width of the tongue gradually decreases. is preferably provided.

According to this, the inclined portion on the placing portion side can be used as the insertion portion of the present invention. Moreover, since the width of the tongue piece on the side of the standing portion gradually increases due to the inclined portion, it can be easily inserted into the insertion portion.

Further, in the packaging tool of the present invention, the tip of the tongue piece is connected to the mounting portion via a second hinge portion that is provided on the mounting portion and is capable of being mountain-folded. formed by one hinge portion, the second hinge portion, and a pair of cut lines connecting both ends of the first hinge portion and the second hinge portion, and a valley fold between the tip end and the base end; having a possible third folding line, and when the erecting section is erected on the first folding line, the rear side of the placing section is bent into a V shape with the third folding line as a vertex. is preferred.

According to this, when the erecting portion is erected, the tongue piece is bent in a V shape with the third fold line as a vertex by the first hinge portion and the second hinge portion, and is bent into the placement portion. protrude behind the As the standing portion is further erected, the apex of the tongue moves toward the mounting portion by rotating about the second hinge, and the tongue is inserted into the insertion portion. Therefore, according to the packaging tool having such a configuration, the tongue piece can be inserted into the inserting portion simply by raising the standing portion.

In particular, in the packaging device comprising a third fold line, the score lines are a first score line extending from the first hinge portion, a second score line extending from the second hinge portion, and a first score line. and a third cut line extending from the tip to the tip of the second cut line along the extension line of the third fold line so that the width of the tongue becomes small, and the insertion part is formed by the third It is preferable that a stepped portion is provided by the three cut lines, and the tongue is brought into contact with the stepped portion when the standing portion is raised by the first folding line.

According to this, since the tongue provided on the standing portion is sandwiched while being in contact with the stepped portion, the standing portion is more reliably supported in the standing state to wrap the package object. can be maintained at

FIG. 2 is an explanatory cross-sectional view showing the deformation process of the plate member of FIG. 1 from the side;

One embodiment of the present invention will be described based on the drawings.

A packaging tool 1 for transporting goods (hereinafter referred to as a packaging tool 1) of this embodiment has a plate member 2 and a flexible film (thin film member) 3, as shown in FIG. A packaging tool 1 holds an object K to be packaged between a plate-like member 2 and a flexible film 3 and accommodates it in an outer box 4 . This outer box 4 may be used as a packaging box as it is, or two or more boxes may be accommodated in a larger packaging box.

As shown in FIG. 2, the plate-like member 2 is a substantially rectangular plate that is divided into a mounting portion 21 and standing portions 22, 22 arranged on both sides of the mounting portion 21. As shown in FIG. The plate member 2 is made of, for example, cardboard or corrugated cardboard.

The placing portion 21 is a portion for placing the packaged goods secured in the central region of the plate-like member 2 . The standing portion 22 is a portion that is continuous with the left and right edges of the placing portion 21 via the first folding line a and is folded upward. The first folding line a corresponds to the first folding line of the present invention.

The first folding line a is a folding line that is parallel to the left and right edges of the plate member 2 and can be valley-folded. Further, the first folding line a and each other folding line described later are formed in a perforation shape by intermittently forming folding grooves on the back surface (not shown), for example. Also, the crease line may be formed, for example, by providing a normal ruled line, a half cut line, a curved line, or the like on the surface.

As a result, the standing portion 22 can be bent to a position facing substantially vertically upward with respect to the placing portion 21 .

The plate-shaped member 2 is formed with a second folding line b that passes through the placing portion 21 and the standing portions 22, 22 and intersects with the first folding lines a, a. The second crease line b is a crease line parallel to the upper and lower edges of the plate member 2 and capable of being valley-folded. In addition, the second folding line b corresponds to the second folding line of the present invention.

Further, on the plate-like member 2, three substantially rectangular tongue pieces 23 are formed on both the left and right sides over the mounting portion 21 and the standing portion 22, respectively. In addition, in the present invention, the number and arrangement of the tongue pieces are not limited to this.

As shown in FIGS. 2 and 3 , the tongue piece 23 includes a substantially trapezoidal body portion 231 and a substantially rectangular connecting portion 232 .

The main body portion 231 is connected to the upright portion 22 via the third folding line c at the left end edge. The third folding line c is a folding line that is parallel to the left and right edges of the plate member 2 and can be valley-folded. In addition, the third folding line c corresponds to the first hinge part of the present invention.

As a result, the body portion 231 is rotatable with respect to the standing portion 22 around the third folding line c.

The connecting portion 232 is connected to the mounting portion 21 via the fourth folding line d at the right edge. The fourth crease line d is a crease line parallel to the left and right edges of the plate member 2 and capable of being mountain-folded. In addition, the fourth folding line d corresponds to the second hinge part of the present invention.

Accordingly, the connecting portion 232 can rotate with respect to the placing portion 21 around the fourth folding line d.

The body portion 231 and the connecting portion 232 are connected to each other at the right edge of the body portion 231 and the left edge of the connecting portion 232 via the fifth folding line e. The fifth folding line e is a folding line that is parallel to the left and right edges of the plate member 2 and can be valley-folded. The fifth folding line e corresponds to the third folding line in the present invention.

By the way, since the first folding line a is not formed on the tongue piece 23, when the standing portion 22 is raised along the first folding line a, the stress is concentrated on the fifth folding line e. As a result, the tongue piece 23 is bent with the fifth folding line e as the apex, and protrudes toward the back side of the plate member 2 .

The tongue piece 23 described above is formed by providing a pair of cut lines 24 on the plate member 2, as shown in FIG. The cut lines 24 extend linearly from both ends of the third fold line c toward both ends of the fourth fold line d with steps.

Explaining using the upper cut line 24 in FIG. The second cut line 242 extending parallel to the upper and lower edges of the plate-shaped member 2 toward the third and a score line 243 .

Since the pair of upper and lower first cut lines 241 are spaced apart toward the left side, the width of the tongue piece 23 in the vertical direction increases toward the left side. In addition, the 1st cut line 241 corresponds to the inclination part of this invention.

Next, the side of the plate-like member 2 that is separated by the cut line 24 and faces the partly separated tongue 23, that is, the region of the plate-like member 2 where the tongue 23 is cut and opened An insert portion 25 is formed.

The insertion part 25 includes a contact part 251 formed by the third cut line 243, and a holding part 252 formed in a predetermined area along the first cut line 241 from both ends of the third cut line 243 and both ends. and Note that the contact portion 251 corresponds to the stepped portion of the present invention.

The flexible film 3 shown in FIG. 1 is formed of a flexible film made of a synthetic resin film such as polyethylene terephthalate, polyethylene, polypropylene, polycarbonate, and polyvinyl chloride. The flexible film 3 is cylindrical, and the plate member 2 is inserted through one opening in the direction along the second folding line b.

The flexible film 3 needs to be formed so as to cover at least the packaging object K in the axial direction, and is formed so as to cover the placement section 21 in the present embodiment.

The length of the flexible film 3 in the circumferential direction is designed to be about the same as or slightly larger than the outer circumference of the plate-like member 2 in the lateral direction so that the plate-like member 2 can be accommodated therein. The flexible film 3 is flexible and stretchable, and the plate-like member 2 can be bent along the second folding line b. The flexible film 3 can also be designed somewhat smaller. That is, the length of the flexible film 3 in the circumferential direction can be appropriately selected according to the size of the packaging object K to be stored.

In this embodiment, the plate-like member 2 is only inserted into the flexible film 3 and is not fixed, but the present invention is not limited to this. The side plate-like member 2 and the flexible film 3 can also be fixed by adhesive/heat welding.

Next, with reference to FIGS. 4A to 4D, a procedure for packaging an object K to be packaged using the packaging tool 1 will be described.

First, as shown in FIG. 4A, the plate-like member 2 is folded in a valley fold along the second folding line b. Next, the packaging object K is inserted between the mounting portion 21 of the plate member 2 and the flexible film 3 . At this time, as described above, the flexible film 3 is loosened by bending the plate-like member 2 in advance, so that the packing object K can be easily inserted.

Next, as shown in FIG. 4B, the plate-like member 2 that has been folded along the second crease line b is restored to a flat plate shape against the tension of the flexible film 3 . As a result, the flexible film 3 is pulled toward the both edge sides of the mounting section 21 and is tensed, pressing the packaging object K against the mounting section 21 . As a result, the packaging object K is fixed at a predetermined position.

Further, as shown in FIG. 4B, the standing portions 22, 22 are folded toward the surface side of the mounting portion 21 along the first folding lines a, a (in the direction of the arrow in FIG. 4B).

As a result, as shown in FIG. 4C, the standing portion 22 gradually stands up, and as shown in FIG. 4D, stands above the placing portion. At this time, since the tongue piece 23 is inserted into the insertion portion 25 and locked, it is possible to prevent the upright portion 22 from being restored by the restoring force of the corrugated cardboard or the like. In addition, the standing portion 22 is prevented from excessively bending toward the upper surface of the mounting portion 21 beyond this position.

As described above, the packaging of the packaging object K using the packaging tool 1 is completed.

In the above description, in FIG. 4B, the plate-like member folded along the second folding line b is returned to its original unfolded state, and then the standing portions 22, 22 are folded along the first folding lines a, a. It has been described that the mounting portion 21 is bent toward the surface side. However, since the second crease line b and the first crease line a intersect, both crease lines cannot be folded at the same time. The folded second fold line b is automatically restored to its original unfolded state.

That is, as shown in FIG. 4A, in a state in which the object to be packaged K is inserted between the mounting portion 21 of the plate member 2 and the flexible film 3, the standing portions 22, 22 are placed on the mounting portion 21. By folding to the surface side, the state of FIG. 4B can be omitted and the state of packaging shown in FIG. 4D through FIG. 4C can be achieved.

Next, with reference to FIGS. 5A to 5C, the operation when the tongue piece 23 is inserted into the insertion portion will be described.

When the standing portion 22 is valley-folded along the first folding line a from the state of FIG. 5A, the main body portion 231 and the connecting portion 232 are gradually bent with the fifth folding line e as the apex, as shown in FIG. 5B. be.

As the erecting portion 22 is further erected, the third folding line c moves rightward (toward the placing portion in the left-right direction) while drawing an arc. As a result, the main body portion 231 supported by the third folding line c is also moved rightward and comes into contact with the contact portion 251 .

As the standing portion 22 is further raised, the body portion 231 is guided by the tip of the abutting portion 251 and protrudes further to the rear surface of the plate-like member 2 . At this time, since the connecting portion 232 is rotated around the fourth folding line d, the leading end (fifth folding line e) of the body portion 231 is guided rightward while drawing an arc.

By the way, the body portion 231 has a substantially trapezoidal shape and is tapered from the fifth folding line e to the third folding line c. Therefore, as the standing portion 22 is raised, the wider region of the tongue piece 23 is gradually inserted into the holding portion 252 of the insertion portion 25 .

Then, when the standing portion 22 is bent approximately 90 degrees to a position facing substantially vertically upward with respect to the placing portion 21, as shown in FIG. As an apex, it is bent in a V shape (about 90°). Further, the main body portion 231 is strongly pressed against the contact portion 251 of the insertion portion 25 to contact it, and is clamped by the clamping portion 252 . At this time, since the plate member 2 is made of corrugated paperboard, the body portion 231, the contact portion 251, and the sandwiching portion 252 are force-fitted while being mutually deformed.

According to the packaging device 1 described above, even if the folded standing portion 22 tries to restore itself by the restoring force of the corrugated cardboard, the tongue piece 23 supported by the standing portion 22 is not inserted into the insertion portion formed on the placing portion 21. Since it is locked by the portion 25, the restoration can be prevented.

Also, at this time, since the tapered tongue piece 23 is inserted as much as possible into the clamping portion 252 of the insertion portion 25, the standing portion 22 exceeds about 90° and the placement portion 21 is excessively bent. Bending to the upper surface side is prevented.

Finally, as shown in FIG. 1, this packaging tool 1 is housed in an outer box 4. As shown in FIG.

At this time, since the wrapping tool 1 is prevented from restoring as described above, it is maintained in a state in which the wrapping object K is wrapped, so that it can be accommodated easily.

Moreover, the packaging tool 1 further has the following specific effects when a wraparound type case is adopted as the outer box.

First, the wraparound type case has a cylindrical main body and closing parts that close the left and right sides of the main body. It consists of an inner flap and a pair of outer flaps connected to the upper and lower edges via fold lines.

When closing the closing portion, the inner flap is folded along the crease line, an adhesive or the like is applied to the surface of the inner flap, and the outer flap is folded along the crease line and adhered.

When performing this bonding, it is preferable to support the inner flaps from the inside so that the inner flaps are not excessively bent toward the inside of the box when the outer flaps are pushed from the outside.

However, there is an inconvenience that the inner flap cannot be supported from the inside while one of the closing parts is closed and the product is enclosed.

On the other hand, according to the packaging device 1 of the present invention, if the upright portion 22 is housed so as to face the closed portion, the inner flap can be supported by the upright portion 22, so that the closed portion can be easily adhered. It can be carried out.

Modifications of this embodiment will be described below.

In the above description, an embodiment in which the tongue piece 23 is connected to the placement section 21 via the connecting section 232 has been described, but the present invention is not limited to this. That is, since it is sufficient if the tongue piece is force-fitted into the insertion portion (holding portion) narrower than the width of the tongue piece, the connecting portion may be omitted. Furthermore, the inner side cut at the cut line 24 is the tongue piece 23, and the opening formed by removing the tongue piece 23 is the insertion portion 25, but the present invention is not limited to this. That is, a groove portion into which the tongue piece is inserted may be separately formed near the center of the mounting portion in the left-right direction from the tongue piece.

In addition, in the above description, an embodiment in which the contact portion is formed by forming the cut lines 24 in a stepped manner has been described, but the present invention is not limited to this. That is, since it is sufficient for the tongue piece to be force-fitted into the insertion portion (holding portion) narrower than the lateral width of the tongue piece, the contact portion may be omitted.

Further, in the above description, the linear first cut line 241 extending downward to the right from the upper end of the third crease line c is described as the inclined portion of the present invention, but the inclined portion of the present invention is not limited to this. That is, since it is sufficient that the tongue piece can be easily inserted into the insertion portion, the inclined portion may have a curved shape such as a trumpet shape, a stepped shape, or may be formed in a part of the main body portion.

In addition, in the above description, an embodiment in which the flexible film 3 is formed to cover the packaging object K in the axial direction has been described, but the present invention is not limited to this. That is, it is preferable that the flexible film 3 is covered up to the standing portion 22 side of the fifth fold line e. According to this, since the tongue piece 23 protrudes from the back surface of the plate-like member 2 with the fifth folding line e as the apex, the flexible film 3 is pulled downward by the tongue piece 23 so that the object A can be wrapped. It is possible to further improve the bearing capacity to
