Japanese National Patent Publication No. 9-501128

  However, in the packaging tool in a state of wrapping the packaging object, the tensioned flexible film member presses the placement portion through the packaging object. Therefore, the plate-shaped member is restored from the state in which each standing portion is bent upward to the original state that is not bent, and may be valley-folded again at the second folding line.

  In view of the above-mentioned point, the present invention aims to provide a packaging tool which can maintain a packing subject in a wrapped state.

  In order to achieve such an object, the packaging device of the present invention is a plate-like member on which an object to be packaged is placed and a cylindrical shape into which the plate-like member is inserted, and is placed on at least the plate-like member. A packaging material provided with the flexible thin film member covering the packaging object, wherein the plate-like member is a placing part on which the packaging subject is placed on the front side; An erected portion connected in series via a first foldable foldable fold on both sides, a cross section of the placement portion and the erected portion, and a second foldable foldable fold of the placement portion and the erected portion A tongue, a tongue protruding from the rising part to the placing part through the valley foldable first hinge part provided in the rising part, and a tongue provided in the placing part, the tongue being inserted An insertion portion that opens so that the side edge of the tongue is provided with an engaging protrusion, and the insertion portion bends the upright portion along a first folding line. When the inserted tongue piece is locked, the tongue piece at the base portion on the first hinge part side of the engagement protrusion is less than the width of the tongue piece at the tip of the engagement protrusion. And an engagement recess having a width equal to or greater than

  Since the plate-shaped member is inserted so that the packaging target object mounted in the mounting part may be covered with respect to the cylindrical thin film member, the packaging tool of this invention, An object to be packaged can be sandwiched between the thin film member and the thin film member. At this time, since the gap is increased by valley-folding the placing portion and the both standing portions by the second folding curve, it is possible to easily insert the packaging object.

  Moreover, since the rising part is continuously provided on both sides of the mounting part via the first bending line, the first bending line and the second bending line intersect with each other, When both standing parts are bent above the mounting part by the first folding line, the second folding line that has been folded first is restored to the original unfolded state, and the flexible thin film member is Tensioned and supported by pressing the packaging object against the placement part.

  At this time, the tongue piece provided on the rising portion is valley-folded by the first hinge portion, and the insertion protrusion provided on the placement portion is the engagement protrusion provided on the side edge of the tongue piece. Is inserted into the engaging recess. The engagement recess has a width smaller than the width of the tongue at the tip of the engagement projection and greater than the width of the tongue at the base on the first hinge side of the engagement projection. The engagement projection is locked in the engagement recess and prevented from coming off. Thereby, an upright part is supported by a mounting part in a standing posture via a tongue piece.

  Therefore, in the packaging tool according to the present invention, since the plate-like member is not valley-folded again at the second folding line by being restored from the standing-up state to the original state from the standing-up state, It can be kept wrapped.

  Further, in the packaging tool according to the present invention, the tongue piece is connected to the mounting portion via a mountain foldable second hinge portion provided in the mounting portion, and the first hinge is provided. Part, the second hinge part, and a pair of score lines connecting both ends of the first hinge part and the second hinge part, and the first hinge part and the second hinge part And a third foldable foldable between the second and third folds, and when the rising portion is erected at the first fold, the third fold is bent at the apex on the back side of the placement portion. It is preferable.

  According to this, when the upright portion is raised, the tongue piece protrudes to the back side of the mounting portion while being bent with the third fold line as a vertex by the first hinge portion and the second hinge portion. To go. When the upright portion is further raised, the apex of the tongue piece moves to the placement portion side by rotation about the second hinge portion, and the engagement provided on the side edge of the tongue piece The protrusion is inserted into the engagement recess of the insertion part. For this reason, according to the packaging tool provided with such a configuration, the engagement projection provided on the side edge of the tongue piece can be inserted into the engagement recess of the insertion portion only by raising the rising portion.

  Further, in the packaging tool of the present invention, for example, the cutting line is projected on the side of the first hinge from the tongue in a direction toward the front side and the second projection on the side of the second hinge. A second projecting portion projecting in the direction of the placement portion from the tongue piece, and the tongue piece includes the engagement projecting portion at a portion corresponding to the first projecting portion, while the insertion portion is The engagement recess may be provided in a portion corresponding to the second protrusion.

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

  An article transport packaging tool 1 (hereinafter referred to as a packaging tool 1) of the present embodiment has a plate-like member 2 and a flexible film (thin film member) 3 as shown in FIG. The packaging tool 1 holds the packaging object K between the plate-like member 2 and the flexible film 3 and accommodates it in the outer box 4. The outer box 4 may be 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 partitioned into a placement portion 21 and upright portions 22 and 22 disposed on both sides of the placement portion 21. The plate-like member 2 is made of, for example, cardboard or cardboard board.

  The placing portion 21 is a portion on which the packaged article secured in the central region of the plate-like member 2 is placed. The upright portion 22 is a portion that is connected to the left and right end edges of the placement portion 21 via a first fold line a and is folded upward. The first fold line a corresponds to the first fold line of the present invention.

  The first fold line a is a fold line that can be folded in parallel with the left and right edges of the plate-like member 2. The first crease line a and other crease lines to be described later are formed in a perforated shape by intermittently providing a bending groove on the back surface (not shown), for example. The crease line may be formed by providing, for example, a normal ruled line, a half cut, a curve, or the like on the surface.

  As a result, the rising portion 22 can be bent to a position facing generally vertically upward with respect to the mounting portion 21.

  The plate-like member 2 is formed with a second fold line b that passes through the placement portion 21 and the upright portions 22 and 22 and intersects the first fold line a and a. The second fold line b is a valley foldable fold line parallel to the upper and lower end edges of the plate-like member 2. The second fold line b corresponds to a second bending line of the present invention.

  Further, the plate-like member 2 is formed with three substantially trapezoidal tongue pieces 23 symmetrically on the left and right sides over the placement portion 21 and the upright portion 22. In the present invention, the number and arrangement of the tongues are not limited to this.

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

  As shown in FIG. 3 taking the lower left tongue piece 23 of FIG. 2 as an example, the main body portion 231 is connected to the upright portion 22 at the left end edge via the third fold line c. The third fold line c is a fold line that can be folded in parallel with the left and right edges of the plate-like member 2. The third fold line c corresponds to the first hinge portion of the present invention. Thereby, the main-body part 231 can be rotated with respect to the standing part 22 centering on the 3rd crease line c.

  The connection portion 232 is continuously provided to the placement portion 21 at the right end edge via the fourth fold line d. The fourth fold line d is a fold line that can be folded in parallel with the left and right edges of the plate-like member 2. The fourth fold line d corresponds to a second hinge portion of the present invention. Thus, the connecting portion 232 is pivotable with respect to the placement portion 21 about the fourth fold line d as an axis.

  In addition, as shown in FIG. 3, the tongue piece 23 is formed by providing a pair of score lines 24 with respect to the plate-like member 2. The cut line 24 extends in a zigzag shape from both ends of the third fold line c toward both ends of the fourth fold line d, and the first fold line 24 is formed on the side edge of the tongue piece 23 in order from the third fold line c side. A protrusion 241 and a second protrusion 242 are formed.

  As a result, in the tongue piece 23, the portion corresponding to the first protrusion 241 is the engagement protrusion 233, and in the placement portion 21, the portion corresponding to the second protrusion 242 is the insertion portion (engagement portion). (Concave portion) 25. The width of the insertion portion 25 (corresponding to the width of the tongue piece 23 at the tip of the second protrusion 242) is x, and the width of the engagement protrusion 233 (the tongue at the tip of the first protrusion 241). Y> x ≧ z, where y corresponds to the width of the piece 23 and z indicates the width of the base of the engagement protrusion 233 on the third fold line c side.

  The tongue piece 23 is provided with a valley foldable fifth fold line e at a position connecting the tips of the second protrusions 242 between the third fold line c and the fourth fold line d. Yes. The fifth fold line e corresponds to a third fold line in the present invention.

  By the way, since the first fold line a is not formed on the tongue piece 23, the stress concentrates on the fifth fold line e when the standing portion 22 is erected at the first fold line a. Thereby, the tongue piece 23 is bent with the fifth fold line e as a vertex, and protrudes to the back surface side of the plate-like member 2.

  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-like member 2 is inserted from one opening in the direction along the second fold 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 portion 21 in the present embodiment.

  The length in the circumferential direction of the flexible film 3 is designed to be approximately the same as or slightly larger than the outer circumference in the short direction of the plate member 2 so that the plate member 2 can be accommodated. The flexible film 3 is flexible and can be expanded and contracted, and the plate-like member 2 can be bent along the second fold line b. The flexible film 3 can be designed to be slightly smaller. That is, the length in the circumferential direction of the flexible film 3 can be appropriately selected depending on the size of the packaging object K to be stored.

  In the present 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 and heat welding.

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

  First, as shown to FIG. 4A, the plate-shaped member 2 is bend | folded in valley fold along 2nd fold line b. Subsequently, the object to be packaged K is inserted between the mounting portion 21 of the plate member 2 and the flexible film 3. At this time, as described above, since the flexible film 3 is loosened by bending the plate-like member 2 in advance, the packaging object K can be easily inserted.

  Next, as shown in FIG. 4B, the plate-like member 2 bent along the second fold 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 and tensioned toward the both end edges of the placement portion 21, and presses the packaging object K against the placement portion 21. By this, the object to be packaged K is fixed at a predetermined position.

  Further, as shown in FIG. 4B, the upright portions 22 and 22 are bent toward the surface side of the placement portion 21 along the first fold lines a and a (in the direction of the arrow in FIG. 4B).

  Thereby, as shown to FIG. 4C, the standing part 22 rises gradually and stands above a mounting part as shown to FIG. 4D. At this time, since the tongue piece 23 is inserted into and locked in the insertion portion 25 as the engagement concave portion as the engagement protrusion 233, the erected portion 22 which is erected is restored by the restoring force of the cardboard or the like. Can be prevented. Further, the rising portion 22 is prevented from being bent to the upper surface side of the mounting portion 21 excessively beyond this position.

  Thus, the packaging of the object to be packaged K using the packaging tool 1 is completed.

  In the above description, in FIG. 4B, the plate-like member 2 bent along the second fold line b is returned to its original unfolded state, and then the upright portions 22 and 22 are moved to the first fold lines a and a. At the surface side of the mounting portion 21. However, since the second fold line b and the first fold line a intersect each other, both the fold lines cannot be folded at the same time. The second fold line b that has been restored is automatically restored to the original unfolded state.

  That is, as shown in FIG. 4A, in a state where the packaging object K is inserted between the placement portion 21 of the plate-like member 2 and the flexible film 3, the upright portions 22 and 22 are placed on the placement portion 21. By folding to the surface side, the state shown in FIG. 4B can be omitted, and the packaging shown in FIG. 4D can be completed via FIG. 4C.

  Next, referring to FIG. 5, the operation when the engaging protrusion 233 of the tongue piece 23 is inserted into the insertion portion 25 as the engaging recess is located on the left side of the plate-like member 2 shown in FIG. 2. The tongue piece 23 will be described as an example.

  When the upright part 22 is valley-folded along the first fold line a from the state where the plate-like member 2 is flat, the main body part 231 of the tongue piece 23 is gradually bent with the fifth fold line e as a vertex.

  When the upright portion 22 is further raised, the third fold line c moves while drawing an arc in the right direction (direction approaching the placement portion in the left-right direction). Thus, the main body portion 231 supported by the third fold line c is also moved rightward.

  Furthermore, when the standing portion 22 is made to stand, the main body portion 231 further protrudes to the back surface of the plate-like member 2, and at this time, the connecting portion 232 is pivoted about the fourth fold line d. Guide the bent portion 231 (fifth fold line e) rightward while drawing an arc.

  By the way, the main body 231 includes a first projecting portion 241 and a second projecting portion 242 by a cut line 24 formed in a zigzag manner on the side edge. Therefore, when the rising portion 22 is raised, the engagement protrusion 233 corresponding to the first protrusion 241 of the tongue piece 23 is gradually made to the insertion portion 25 corresponding to the second protrusion 242. It will be inserted.

  Then, when the upright portion 22 is bent approximately 90 ° to a position facing generally vertically upward with respect to the placement portion 21, as shown in FIG. 5, the main body portion 231 is V-shaped with the fifth fold line e as an apex. (About 90 °). At this time, the tip end of the main body portion 231 is continuously connected to the fourth fold line d via the coupling portion 232, and the engagement projection 233 of the main body portion 231 is inserted at the base on the third fold line c side. It is locked to the part 25. As a result, since the plate-like member 2 is formed of corrugated paperboard, the engagement protrusion 233 of the main body 231 is forcibly fitted into the insertion portion 25.

  According to the wrapping tool 1 described above, even if the bent upright portion 22 is to be restored by the restoring force of the cardboard, the tongue piece 23 supported by the upright portion 22 is formed on the mounting portion 21. Since it is locked by the part 25, the said restoration can be prevented.

  Further, at this time, since the base of the engaging protrusion 233 on the third folding line c side is engaged with the insertion portion 25, the standing portion 22 exceeds approximately 90 ° and the placing portion 21 is excessively formed. It is prevented that it bends to the upper surface side of.

  Finally, as shown in FIG. 1, the packaging tool 1 is housed in the outer case 4.

  Since the restoration | restoration is prevented at this time, since the packaging tool 1 is maintained in the state which wrapped the packaging target K, it can accommodate easily.

  Moreover, the packaging tool 1 further has the following characteristic effects, when a wraparound type case is employ | adopted as an outer case.

  First, the wrap-around type case includes a cylindrical main body portion and a closing portion that closes the left and right sides of the main body portion, and each closing portion is connected to the left and right edges of the main body portion via a crease line. And a pair of outer flaps connected to upper and lower edges via fold lines.

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

  When performing this bonding, it is preferable to support the inner flap from the inner direction so that the inner flap does not bend too much in the inner direction of the box when the outer flap is pushed from the outside.

  However, there has been a disadvantage that the inner flap can not be supported from the inside in a state in which one closed portion is closed to contain the product.

  On the other hand, according to the packaging tool 1 of the present invention, since the inner flap can be supported by the standing portion 22 if the standing portion 22 is stored so as to face the closing portion, the closing portion can be easily bonded. It can be carried out.

  Hereinafter, modifications of the present embodiment will be described.

  In the above description, the embodiment has been described in which the tongue piece 23 is connected to the placement portion 21 via the connecting portion 232, but the present invention is not limited to this. That is, since it is sufficient if the engaging protrusion 232 of the tongue piece 23 is forcibly fitted to the insertion portion 25, the connecting portion 232 may be omitted.

  Moreover, although the said description demonstrated embodiment by which the 1st protrusion part 241 and the 2nd protrusion part 242 were formed of the zigzag-shaped cutting line 24, this invention is not limited to this. That is, the cut line 24 may have any shape as long as the first projecting portion 241 and the second projecting portion 242 can be formed, and may be wavy.

  In the above description, the embodiment has been described in which the main body portion 231 is bent in a V shape with the fifth fold line e as the apex, but the present invention is not limited to this. That is, the main body portion 231 may be bent in a U-shape by two fold lines.

  Moreover, in the said description, although flexible film 3 demonstrated embodiment formed to the extent which covers the packaging target K in an axial direction, this invention is not limited to this. That is, it is preferable that the flexible film 3 covers the upright portion 22 side from the fifth fold line e. According to this, since the tongue piece 23 protrudes on the back surface of the plate-like member 2 with the fifth folding line e at the top, the flexible film 3 is pulled downward by the tongue piece 23 so that the packaging object A The bearing capacity can be further improved.
