Description

  The present invention relates to a support sheet and a packaging material set.

  When an article is housed in a box, a support formed of a single sheet material may be disposed in the box. As such a support, one having a holding hole for inserting the lower part of the article in a top panel which is held at a distance from the bottom of the box is widely used. In such a support, in order to improve the function of holding the article, a tongue protruding inside the holding hole is provided, which tongue is bent downward when the article is inserted into the holding hole. Many are designed to be in intimate contact with the side of the article.

  Even with the support as described above, the retention of the article may not be sufficient. For example, if the planar shape of the part to be inserted into the support of the article is circular, there is a possibility of horizontal rotation in the support. The disadvantage of such horizontal rotation is that when the front of the box is opened and the article is displayed, the appearance becomes worse, or the upper part of the article partially protrudes sideward when the projection May come into contact with the inner wall of the box and cause damage. As a specific example, when the article to be stored in the box is potted, the flowers and leaves may be projected asymmetrically in the horizontal direction from the pot inserted into the holding hole and designed to be viewed from a specific direction There is.

  For example, in Japanese Patent Application Laid-Open No. 2000-53181, in a package for storing a potted plant in a box, a support (a lateral deviation regulating member) having a holding hole for inserting a pot is used and the lower end is pierced into the pot It has been proposed to prevent vertical movement and tilting of the pot by using a vertical movement regulating member whose upper end abuts on the ceiling surface of the box.

  Although the above publication does not mention the horizontal rotation of the pot, it is clear that the flowers may be damaged if the potted plant described in the figure rotates horizontally. Also in the vertical movement regulating member of the above-mentioned publication, it is considered possible to prevent the horizontal rotation of the potted plant, for example, by extending the upper end along the diagonal of the ceiling surface. However, the work of inserting such an up and down movement restricting member is complicated, and there is a risk that the up and down movement restricting member may damage the roots of the flower and may impair the appearance when displaying.

JP 2000-53181 A

  In view of the above problems, the present invention has an object to provide a support sheet and a packaging material set capable of suppressing horizontal rotation of an article.

  A support according to one aspect of the present invention made to solve the above problems is a support formed of a single sheet material and disposed in a box and assembled on a support for holding an article. Sheet having an upper surface panel having a holding hole forming portion forming a holding hole having a circular shape in a plan view circular shape into which an article is inserted, and the upper holding hole forming portion is at least a part of the inner edge of the holding hole The plurality of straight folds easy to form and the plurality of tongues extending respectively from the easy folds and bent downward when the article is inserted into the holding hole, the plurality of folds The easy bending line is characterized in that it includes two easy bending lines whose normals are inclined with respect to a straight line connecting the center point thereof and the center of gravity of the holding hole and whose inclination directions are different from each other.

  In the sheet for a support, the plurality of easy-to-bend lines that become the base end edge of the tongue piece are inclined with respect to a straight line connecting the normal point to the center point of the holding hole. When the article is inserted into the holding hole, the tongue piece inclines and presses the side edge of one side to the side of the article. The tongues thus inclined make the friction force asymmetric and allow the article to rotate from the side where the side edges do not contact to the side where the side edges come in contact, but inhibit the opposite side from rotating. The support sheet has two easy-to-bend lines with different directions of inclination, so that rotation of the article in both directions can be prevented by either tongue.

  In the said support sheet, it is preferable that the inclination angle of the normal line of the said bending easy line is 0.5 degrees or more and 5.0 degrees or less. As described above, by setting the inclination angle of the normal to the bending easy line within the above range, it is possible to firmly hold the article while improving the effect of suppressing the rotation of the article by the tongue piece.

  In the sheet for a support, the inclination directions of the normals of the plurality of adjacent easy bending lines may be equal. As described above, by making the inclination directions of the normals of the plurality of adjacent easy bending lines equal, it is possible to prevent the adjacent tongues from inhibiting the rotation suppression effect of the articles by the tongues. Horizontal rotation can be suppressed more effectively.

  In the seat for a support, the tongue piece may be disposed continuously over the entire circumference of the holding hole. In this manner, by arranging the tongues continuously along the entire circumference of the holding hole, more tongues suppress the rotation of the article, thereby more reliably suppressing the horizontal rotation of the article. be able to.

  The packaging material set which concerns on another aspect of this invention is equipped with the sheet | seat for said supports, and the sheet | seat for boxes assembled in the box which accommodates the support formed by assembling the said sheet | seat for said supports. In the package formed by assembling the packaging material set, since the support formed by assembling the support sheet suppresses horizontal rotation of the article, the article can be prevented from being horizontally rotated and damaged. Since the article can be kept facing forward, the appearance when displaying the article is good.

  Here, “circular” means a shape in which the difference between the radius of the circumscribed circle and the radius of the inscribed circle is 10% or less of the radius of the circumscribed circle.

  The support sheet and the packaging material set of the present invention can form a support and a package capable of suppressing horizontal rotation of an article.

It is a top view (development view) showing a packaging material set of one embodiment of the present invention. It is a disassembled perspective view of the package body which assembles the packaging material set of FIG. It is an enlarged plan view of the sheet | seat for supports of the packaging material set of FIG. It is a top view of the sheet | seat for support bodies of embodiment different from FIG.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings as appropriate.

First Embodiment
The packaging material set which concerns on FIG. 1 at one Embodiment of this invention is shown. The packaging material set comprises a support sheet 1 which is itself another embodiment of the invention and a box sheet 2. The support sheet 1 and the box sheet 2 of the packaging material set are each formed of one sheet material.

  As shown in FIG. 2, the support sheet 1 is assembled on a support S supporting an article P to be packaged, and the box sheet 2 is assembled on a box B accommodating the support S. That is, the support S formed by assembling the support sheet 1 is disposed in the box B formed by assembling the box sheet 2 and used to hold the article P.

  As articles P to be packaged using the packaging material set, for example, potted plants etc. can be assumed.

  As a sheet material for forming the support sheet 1 and the box sheet 2, for example, a corrugated sheet, a plastic board, a cardboard etc. can be used, and among them, a corrugated sheet is particularly preferably used. The sheet material forming the support sheet 1 and the sheet material forming the box sheet 2 may be different.

  The corrugated sheet may be a so-called double flute in which each core is sandwiched between three liners, as well as one in which both sides of one core are sandwiched by a pair of liners. It may be a so-called single-faced cardboard in which a liner is attached only to one side of the sheet.

  In FIG. 1, a thick solid line indicates an edge formed by cutting the sheet material, and a thin solid line indicates the back surface of the sheet material (the surface on the side disposed inside the support S in the assembled state and the box B) In the surface disposed on the inner side, creases are formed by pushing.

[Sheet for support]
As shown in detail in FIG. 3, the support sheet 1 has four rectangular side panels (a pair of long sides extending in equal lengths from each side edge of the rectangular top panel 11 and the upper panel 11). A side panel 12 and a pair of short side panels 13).

<Top panel>
The upper surface panel 11 has the holding hole formation part 14 which forms the holding hole H of planar-view circular shape in which the articles | goods P are inserted.

  The holding hole forming portion 14 may be formed to be offset from the center of the top panel 11. In the present embodiment, the holding hole forming portion 14 is disposed at substantially equal distances from the pair of long sides and one short side of the rectangular upper surface panel 11, and the distance to the other short side is large. Thereby, even when the upper part of the article P (for example, a flower or a leaf of a plant planted in the flowerpot) projects asymmetrically in plan view from the lower part (for example, a flowerpot) of the article P inserted into the holding hole H It can position and hold so that the upper part of article P may not contact the side wall of box B.

(Holding hole formation part)
The holding hole forming portion 14 extends from the plurality of linear easy bending lines 15 forming at least a part of the outer edge of the holding hole H and the easy bending line 15, and inserts the article P into the holding hole H And a plurality of tongues 16 which can be bent downward when being pressed.

  The outer edge of the holding hole H in the present embodiment connects between the plurality of (16) bending easy lines 15 and the ends of the bending easy lines 15 and a cutting line 17 which defines the side edges of the tongue 16. It is formed of a part of That is, in the present embodiment, the tongues 16 are arranged continuously over the entire circumference of the holding hole H. Thus, by arranging the plurality of tongues 16 continuously along the entire circumference of the holding hole H, the article P is firmly held so as not to move in the horizontal direction, and the article P is rotated in the horizontal direction. This can be suppressed more reliably.

  More specifically, in the support sheet 1 of the present embodiment, each of the bending easy lines 15 is inclined relative to a straight line Lr whose normal line Ln connects the central point C and the center of gravity G of the holding hole H. There is. Thereby, the tongue 16 is inclined relative to the straight line Lr, and the side edge of one side is pressed relatively strongly against the article P, whereby the friction force between the tongue 16 and the article P becomes horizontally asymmetric in the horizontal direction. . Thereby, the tongue piece 16 suppresses horizontal rotation of the article P in one direction corresponding to the inclination direction to the bending easy line 15.

  In addition, the inclination directions of the normal lines Ln of the bending easy lines 15 are different from each other on the left and right in FIG. That is, in the sheet 1 for supports, the plurality of easy bending lines 15 are such that the eight easy bending lines 15 on the right side are inclined clockwise so that the shape of the holding holes H becomes symmetrical. The book bending easy line 15 is inclined counterclockwise.

  As in the present embodiment, by making the inclination directions of the normal lines Ln of the plurality of adjacent easy bending lines 15 equal, the adjacent tongues 16 have the same side edge (side edge not adjacent) as the article P Since the pressure contact is strong, it is difficult to disperse the contact pressure, and the effect of suppressing the rotation of the article P is increased.

  As a lower limit of the inclination angle with respect to the straight line Lr of the normal line Ln of the bending easy line 15, 0.5 ° is preferable, and 1.0 ° is more preferable. On the other hand, the upper limit of the inclination angle of the normal line Ln to the bending easy line 15 is preferably 5.0 °, more preferably 4.0 °. If the side edge of the tongue piece 16 can not be pressed against the side surface of the article P due to dimensional error or play when the inclination angle of the normal line Ln of the bending easy line 15 does not reach the above lower limit, the article P is rotated. There is a possibility that it can not be suppressed sufficiently. On the contrary, when the inclination angle of the normal line Ln of the bending easy line 15 exceeds the upper limit, the pressure is concentrated on the end of the bending easy line 15 and the sheet material is buckled to stably hold the article. It may not be possible.

  In the present embodiment, each tongue 16 is centered on the bending easy line 15, a pair of cutting lines 17 formed on a straight line passing through the center of gravity G of the holding hole H, and the center of gravity G of the holding hole H. It is demarcated by the tip edge 18 formed in circular arc shape.

  The tongue piece 16 is bent downward at the bending line 15 when inserting the article P into the holding hole H, and abuts on the side surface of the article P. The tongue piece 16 pushes the article P toward the center of the holding hole H by trying to bounce upward by the restoring force (elastic force) of the sheet material. Thus, the support S formed by assembling the support sheet 1 holds the article P in the holding hole H without rattling.

  Adjacent tongues 16 are separated by a cutting line 17. The straight side edge of the tongue 16 defined by the cutting line 17 can abut continuously on the cylindrical or conical side of the article P, so that it is between the tongue 16 and the article P The friction can be increased to improve the anti-rotation effect of the article P.

  In the present embodiment, the tip edges 18 of the plurality of tongues 16 are formed so as to continuously draw a single circle. This facilitates the manufacture of a die for cutting the sheet material to form the leading edge 18.

  As a lower limit of the number of tongue pieces 16, 4 is preferable and 6 is more preferable. On the other hand, 32 is preferable and 24 is more preferable as the upper limit of the number of tongues 16. If the number of tongues 16 is less than the above lower limit, the holding of the article P may be insufficient. On the contrary, when the number of tongues 16 exceeds the above-mentioned upper limit, there is a possibility that the effect which controls rotation of article P may become insufficient because the contact pressure power to the article of each tongue 16 becomes small.

  As a minimum of length (length on normal Ln) of tongue piece 16, 10 mm is preferred and 15 mm is more preferred. On the other hand, as a maximum of length of tongue piece 16, 8 cm is preferred and 5 cm is more preferred. If the length of the tongue piece 16 is less than the above-mentioned lower limit, the friction between the side edge of the tongue piece 16 and the side surface of the article P becomes small and the effect of suppressing the rotation of the article P may be insufficient. is there. On the contrary, when the length of the tongue piece 16 exceeds the above-mentioned upper limit, the tip end edge 18 becomes far from the bending easy line 15, the pressing force against the article P becomes small, and the effect of suppressing the rotation of the article P is not good. It may be enough.

<Side panel>
The side panels 12 and 13 support the upper surface panel 11 so as to float from the bottom surface of the box B in an assembled state, and form a space below the upper surface panel 11. The side panels 12 and 13 maintain a state of being bent at a right angle to the top panel 11 by closely contacting the side wall inner surface of the box body formed by assembling the box sheet 2 by the reaction force of the sheet material.

  The extension length of the side panels 12 and 13, that is, the height of the support S formed by assembling the support sheet 1 is selected so that the position for holding the article P can be optimized.

[Sheet for box]
The sheet | seat 2 for boxes can be assembled to the box B which can accommodate the articles | goods P, and the inner bottom part of this box B is comprised so that accommodation of the support body S which assembles the sheet | seat 1 for supports is possible.

  The box sheet 2 of the present embodiment is continuously provided in the lateral direction, and four side wall panels (a pair of long side wall panels 21 and a pair of short side wall panels 22 which constitute four side walls of the box B in an assembled state) A pair of bottom outer flaps 23 extending from the lower edge of the long side wall panel 21 and a pair of bottom inner flaps 24 extending from the lower edge of the short side wall panel 22; And a pair of in-lid flaps 26 extending from the upper edge of the short-side wall panel 22 and a seam 27 connecting the four side panels in a tubular shape.

  This box sheet 2 is defined in JIS-Z 1507 (2013) as a code number 201, and is generally called A-type. The box sheet 2 is generally connected to the four side wall panels 21 and 22 in the form of a tube by means of a seam 27 and is provided to the user in a flat folded state.

<Advantage>
The sheet 1 for support of the packaging material set is a straight line Lr whose normal line Ln connects the center point C and the center of gravity G of the holding hole H as the bending easy line 15 which becomes the base end edge of the tongue piece 16 When the article P is inserted into the holding hole H, the tongue 16 inclines so that the side edge of one circumferential direction side presses the side edge of the article P against the side face of the article P due to the inclination. The inclined tongues 16 allow the article P to rotate in the direction of pressing the side edge but suppress the rotation to the opposite side. Since the support sheet 1 has two bending easy lines 15 whose inclination directions are different from each other, rotation of the article P in both directions can be prevented by any of the tongues 16.
