Description

  The present invention relates to a packaging cushioning material and a packaging set which together accommodate a packaged item in a packaging box and perform a cushioning function, and in particular, interpose the packaged item interposed above or below the packaged item. The present invention relates to a cushioning material and a packaging set for preventing damage due to movement.

    Conventionally, as a presser lid that is inserted into a packaging box and holds an object to be packed, a folded piece having an engaging projection from the corrugated cardboard to the tip, and a fold line is formed on the folded piece. An engagement hole is formed in the fold, and the bent piece is bent into a mountain shape at the fold line portion, and the engagement protrusion is engaged with the engagement hole to assemble the spacer (patent). Reference 1).

  Conventionally, as a packing cushioning material that can protect the articles stored in the outer box, the bottom plate on which the articles are placed is formed as a polygon with two adjacent sides forming an obtuse angle, with an end plate on one side and a corner plate on the other side. A connecting portion that connects the base end of the end plate and the corner plate is provided, and a diagonal line that is inclined toward the corner plate is inserted at the boundary between the end plate and the connecting portion, starting from the corner of the bottom plate. The thing which put the valley fold line in the both sides of this, and inserted in the outer box is disclosed (refer patent document 2). This cushioning material for packing is used to insert a valley fold line on both sides of the end plate and insert it into the outer box, so that the end plate bends inward along the oblique fold line and the valley fold line. In addition to being pressed down, the corner plate stands up and tilts outward so as to contact two adjacent inner plates of the outer box, and the outer box is reinforced by being supported by the corner plate.

  However, although the former presser lid body has a cushioning effect of moving upward by pressing the entire upper surface of the object to be packed, since it has a structure in which only the upper part of the object to be packed is pressed by the plate surface, It was not possible to regulate the movement to the side.

  In addition, the latter packing cushioning material is to hold the side and upper part of the packed object by the corner plate and the end plate, but a part of the end plate bent upward along the periphery of the packed object is partially provided. The folded corner plate is deformed when a strong impact or an external force in the direction of rotation is applied to the upper or lower side of the package, such as when the entire outer box falls over. Or the article locking state may be released. For this reason, it is impossible to stably control from the upper side to the side, and there is no restriction on the lifting or slugging of the packaged object in the oblique direction against strong impact on the upper side or the lower side or external force in the rotational direction. It was enough.

  In addition to the presser lid and the cushioning material for packing, as shown in FIG. 18, the four sides of the upper presser plate (1 ′) of the object to be packaged (O) are bent downward to form four sheets. The inner extension plate (2 ') is formed, and the extension piece (31', 32 ') at each end of the four sides is folded back to the valley side twice and brought into contact with the inner side surface of the outer box. 102 ′), the first extension piece (31 ′) extending outward and the second extension piece (32 ′) extending upward along the inner side surface of the packing box (102 ′). There is an upper cushioning material that covers and supports O) at the top. The upper cushioning material simultaneously holds the upper and side parts of the article by the upper presser plate (1 ′) and the inner side plate (2 ′) of the four-side circumferential portion, and the second extending piece (32 ′) is a packing box ( 102 '), it has a structure that exhibits lateral movement restriction performance and buffer performance (FIG. 18 (a)).

  However, even this upper cushioning material has a strong impact (external force (F2)) or external force (F1) in the rotational direction on the upper oblique side or lower oblique side when the article is dropped in the upside down direction. ), The first extension piece (31 ') is deformed and stretched obliquely, and the upper presser plate (1') is lifted and covered. The upper corner of the package (O) sometimes received an impact (see the vicinity of the upper right in FIG. 18B).

  The present invention has been made in view of such circumstances, and can stably hold the upper part and the side part of the object to be packed, or can stably hold the lower part and the side part, so that either the upper part or the lower part can be obtained. And a cushioning material for packing that sufficiently exhibits movement restriction performance and cushioning performance in multiple directions including the side part, in particular, strong impact or rotational direction on the upper diagonal side or lower diagonal side of the packaged item It is an object of the present invention to provide a packaging cushioning material that can exhibit upward or obliquely upward movement restriction performance and cushioning performance even when an external force is applied.

Or at least one of the above)).

According to this configuration, in the assembled state, the extension destination portions (32) of the plurality of extension plates (3) are in pressure contact with the inner side surfaces (102S) of the packaging box (102) with a restoring force due to bending. . Accordingly, the top plate (1) and the inner plate (2) move in the upper space (S1) or the side space (S3), or move in the lower space (S2) or the side space (S3). Can be regulated. In addition to this restriction, each of the vertical plates (4) arranged in the plan view peripheral portion of the top plate (1) is erected with one side as the vertical direction, and the inner side surface (102S) or lid of the packing box (102) It will be in the state protruded to at least one of the inner surfaces (102L) (for example, refer FIG. 4).

In addition to this restriction, each of the vertical plates (4) arranged in the plan view peripheral portion of the top plate (1) is erected with one side as the vertical direction, and the inner side surface (102S) or lid of the packing box (102) It will be in the state protruded to at least one of the inner surfaces (102L) (for example, refer FIG. 4). The plurality of protruding vertical plates (4) are arranged radially in plan view as a whole, and one end (side one end (4S) / upper one end (41U)) or connecting piece (5 / 6/7) is close to or in contact with at least one of the inner surface (102S) and the lid inner surface (102L) of the packing box (102), so that the upper space ( The movement in S1) and the deformation of the bending structure of each plate are surely restricted.
In particular, each vertical plate (4) standingly accommodated in the packaging box (102) is provided in an upper space (S1) or a side space (S3) in the radial direction of the packaging box (102) in plan view, that is, in a sectional view. In the packing box (102), the upper corner of the packing box (102) has a single vertical surface and is interposed (see, for example, FIG. 5). Even if an external force (F2) obliquely upward or an external force (F1) in the rotational direction is applied to the packaged object, for example, as shown in FIG. ) The assembled shape of itself will be maintained.

Further, in this configuration, each vertical plate (4) is formed by connecting the front or side of each of the plurality of inner plates (2) with a partial cut line, or the top plate (1). It is preferable that a plurality of portions on each side of the circumference are cut out by a partial cut line and connected. According to this, the movement of the vertical plate connection boundary (24F) of the inner plate (2) or the top plate (1) is effectively restricted.
The top plate (1), the inner plate (2), the extension plate (3), and the vertical plate (4) in the buffer body (100) of this configuration are further configured integrally with a bent portion. Is preferred. For example, as shown in FIG. 1, FIG. 7A, etc., it is preferable that the sheet is developed in a developed state on one side having a cut portion. If it has such an unfolded state, the buffer body (100) in the unfolded state can be obtained by punching out a single piece of paperboard, etc. It can be assembled by a machine such as an automatic folding machine.

  Moreover, in the said structure, it is preferable to accommodate at least the inner surface (102S) of a packaging box (102), or to be accommodated in contact with at least the inner surface (102S) of a packaging box (102). As for how to contact the packing box (102), when at least one of the side end (4S) or the upper end (41U) of the vertical plate (4) is in surface contact with the inner surface of the box (4) When the corner of the plate end of at least one of the side piece end (4S) or the upper piece end (41U) is in contact with a corner formed by two adjacent inner surfaces, from the vertical plate (4) to the upper part or the side part This includes any case where at least one of the continuous connecting pieces (first series connecting piece (5), second connecting piece (6), third connecting piece (7)) is in surface contact with the inner surface of the box.

  Among the above-described configurations, in particular, the vertical plate (4) is in a state where the vertical plate upper portion (41) projects upward or downward from the top plate (1) in an assembled state, and has a single vertical plate. Standing up in each radial direction, upper one end (upper piece end (41U)) or upper connecting piece (first series connecting piece (5) / third connecting piece (7) connected upward from the vertical plate (4). )) Is accommodated in a state in which one of the surfaces is in contact with the lid inner surface (102L) or the bottom surface (102B) of the packaging box (102). Thereby, the movement of the article to be packed (O) in the upper space (S1) or the lower space (S2) is surely restricted or buffered.

  In addition, the planar view radiation direction refers to a direction extending from the vicinity of the center in the plan view to the outside in three or more surrounding directions. Further, the number of the vertical plates (4) is not limited, but a buffer function in a plurality of directions in plan view can be achieved by using a plurality of vertical plates. Further, the vertical plate is connected to either the inner plate (2) or the top plate (1), thereby intervening independently of the buffering function by the extended plate and exhibiting the buffering function.

  [2] In the packing cushioning material, a plurality of vertical plates (4) are connected from the side of each inner plate (2), and this connection boundary (vertical plate connection boundary (24F)) is used as the inner plate. (2) It is preferable to consist of the continuous piece formed by bend | folding diagonally with respect to.

  Each of the vertical plates is extended to the side portion of the inner plate (2) and is in an assembled state in which it is folded back obliquely with the extended boundary as a bent side. When the article to be packed (O) is packed in this assembled state, the upper end (41U) and the side end (4S) of the vertical plate (4) are respectively connected to the inner surface (102L) or the bottom surface (102L) of the packing box (102). 102B) and the inner side surface (102S) adjacent to this can be simultaneously contacted. According to the above configuration, one of the upper and lower sides of the vertical plate (4) and the two sides are the two sides (the lid inner surface (102L) / the bottom surface (102B) of the upper corner of the packaging box (102) in the longitudinal sectional view. And the inner side surface (102S) are accommodated in a state where they can be contacted (see FIGS. 5 and 17). By simultaneously contacting the two corner surfaces 2 in the longitudinal sectional view of the packaging box (102) on either the upper or lower side and the outer side, a vertical and horizontal screen function is achieved.

  Each vertical plate (4) is composed of a connecting piece connected from the side portion of the inner plate (2) surrounding the side portion of the article (O) to be packed, and the connecting piece has a valley with an obtuse bending angle outward. It will be folded and will be in the state which spread to diagonally outward with respect to each inner side board (2) (refer the broken line arrow of FIG. 4). The vertical plate (4) is erected in a state of being firmly supported in the vertical direction by being connected from each side portion of the inner plate (2) folded back in the vertical direction.

  According to the said structure, each vertical board (4) cuts off the specific other side of the adjacent inner side board (2), and is connected and formed in the specific one side of the inner side board (2) used as connection object. (See, for example, FIGS. 1 and 2). In particular, the side portions in the specific direction of each of the plurality of inner plates (2) are partially cut by a partial cut line (4C) having a specific shape, and the vertical plate connecting boundary (24F) has an obtuse angle of more than 90 degrees and less than 180 degrees. In the assembled state in which the bent portion is bent inwardly in the valley folding direction, the vertically converged vertical pieces formed with the upper side longer than the lower side are in the upper space (S1) and the side space (S3) in the assembled state. It will be arranged in. A plurality of vertical plates (4) are connected to one specific side of each inner plate (2) in the same shape, and the plurality of vertical plates (4) are bent inward at substantially the same angle in a substantially uniform direction. Thereby, a some vertical board (4) can be formed, suppressing the fall of whole intensity | strength.

  Moreover, according to the said structure, in order to ensure a vertical board (4) by notching an inner side board (2) without notching a top board (1), ensuring a sufficient protection surface by a top board (1), The formation area of the vertical plate can be obtained relatively freely. For example, in addition to the trapezoidal partial cut line (4C) as shown in FIG. 1, various cut partial lines (4C) shown in FIG. The selection of any one of these partial cut lines (4C) means that the shape of the vertical plate is changed according to the side protection strength required for the inner plate (2), and the vertical plate (4) is interposed. This is a buffering adjustment method for adjusting the regulation strength or buffering property.

  [4] In any of the above packing cushioning materials, the packing box includes a polygonal accommodation space having a plurality of corners in plan view, and the plurality of vertical plates (4) are respectively provided. It is preferable that it consists of a vertical piece which extends toward one of the corners and is in contact with two adjacent inner surfaces constituting the corner.

  As in the above configuration, in the polygonal packaging box in plan view, each vertical plate (4) extends obliquely toward one of the corners of the polygonal storage space in plan view, It is accommodated in the corner portion in a state where it can contact the inner surface. The plurality of vertical plates (4) expands in the planar view radial direction as a whole in the accommodation space, so that the movement of the vertical plates (4) in each direction of the planar view is regulated substantially equally. In particular, the buffering direction due to the interposition of the vertical plate is specified as one direction of the accommodated corner, so that the buffer function to the outside of the stored corner and the plan view of the packaging box adjacent to the corner The buffer function in each direction of the two sides is exhibited. Further, if the number of vertical plates is three or more, it has a buffering function in three or more directions in plan view, and the circumferential uniformity of the buffering function is improved.

(Operation of Example)
In the cushioning material for packing described in the first to tenth embodiments, the top plate (1), the inner plate (2), the extension plate (3), and the vertical plate (4) are integrated with each other through a bent portion. In the assembled state, each extension destination part (32) of the plurality of extension plates (3) is packed with a restoring force due to bending, while being configured and developed in a single-sided development state having a cut part. By pressing each inner side surface (102S) of the box (102), the movement of the top plate and the inner plate in the upper space (S1) or the movement in the side space (S3) is regulated and assembled. In the state, the plurality of vertical plates (4) extend radially in plan view as a whole, and one end (side one end (4S) / upper one end (41U)) or connecting piece (5 / 6/7) are the inner surface (102S) or the inner surface (102L) of the packing box (102), respectively. At least by contact with either, it is possible to restrict the movement of the top plate, the inner plate, and side peripheral plates each upper space (S1) within. In this assembled state, each of the vertical plates (4) arranged radially in a plan view is erected and integrally protrudes from the inner surface (102S) to the inner surface (102L) of the packaging box (102). (See, for example, FIG. 4). Further, each vertical plate (4) has one surface in the vertical direction in the upper space (S1) and the side space (S3) in the radial direction of the packing box (102) in the plan view, that is, in the upper corner in the cross-sectional view. (See, for example, FIG. 5). Even if an external force (F2) obliquely upward or an external force (F1) in the rotational direction is applied to the packaged object, for example, as shown in FIG. ) The assembled shape of itself will be maintained.

  Furthermore, each vertical plate (4) described in Examples 1 to 11 is connected and formed from the front or side of each inner plate (2), or is connected and formed from each circumferential portion of the top plate (1). Therefore, the movement of the vertical plate connection boundary (24F) of the inner plate (2) or the top plate (1) is effectively restricted.

  Furthermore, since the shock absorber (100) described in the first to eleventh embodiments can be easily assembled from the unfolded state of a single plate without a locking operation, a machine such as an automatic folding machine. The assembly by is also possible. However, the above configuration includes both the case where it contacts at least the inner surface (102S) of the packaging box (102) and the case where it contacts at least the inner surface (102S) of the packaging box (102). Further, when the vertical plate (4) is in contact with the packing box (102), the vertical plate (4) is in contact with at least one of the side end surfaces (4S) or the upper one end (41U) of the vertical plate (4). ) To the upper part or the side part (the first series of connection pieces (5), the second connection piece (6), the third connection piece (7)), when contacting at least one side (plate surface), Both are included.

Among the above-described configurations, in particular, the vertical plate (4) described in the first to tenth embodiments is in an assembled state in which the vertical plate upper portion (41) is above the side and above the top plate (1), i. Projecting diagonally upward and having a vertical plate on one side. The vertical plate (4) projecting diagonally upward in this way is either one upper end (upper piece end (41U)) or an upper connecting piece (first continuous contact piece (5)) that extends upward from the vertical plate (4). / Any one surface of the third connecting piece (7) is in contact with the lid inner surface (102L) of the packing box (102), so that it is buffered in the upper space (S1), and the packaged object (O) The movement is surely restricted (see FIGS. 2 and 5).
Moreover, in the packaging set of Example 3 including the said Example 11, as shown in FIG. 17, two buffer bodies (100) are integrated facing a symmetrical direction up and down. Among these, the lower shock absorber (100) has four vertical plates (4) which have a vertical plate on one side and project downward, and the vertical plates (4) of the lower shock absorber (100). ) Each lower one end (upper one end (41U)) is in contact with the inner surface (102L) of the lid of the packing box (102), so that it is buffered in the lower space (S2), and the object to be packed (O) The movement of this is surely regulated.

  In addition, a plurality of vertical plates (4) are provided to extend outward in the radial direction in the plan view and stand up, so that a buffering function in a plurality of directions in the plan view can be efficiently obtained. Further, each vertical plate (4) is connected to a side portion in a specific direction of each of the plurality of inner plates (2), and is assembled so that one end thereof faces the corner portion of the packing box in an oblique direction. Thus, a buffering function in two or more directions (the height direction, one side, and the other side orthogonal to the one side) can be obtained at the same time.

Moreover, in the packaging set of the said Examples 1-3, a some vertical board (4) is provided in a row from the side part of each inner side board (2), and an obtuse angle (above 90 degree | times) is made to this vertical board connection boundary (24F). It consists of a vertical piece that is bent upright with respect to the inner plate (2) at a bending angle of less than 180 degrees, and in the assembled state, the upper one end (41U) and the side one end (4S) 102) is preferably in contact with the inner surface (102L) and the inner surface (102S) at the same time. That is, each vertical plate is extended to the side of the inner plate, and the upper side and the side of each vertical plate are accommodated in contact with two adjacent surfaces in the packaging box (102) simultaneously. It is the structure which specified.
According to the above configuration, the vertical plate (4) is accommodated in contact with the two sides (the lid inner surface (102L) and the inner side surface (102S)) of the upper corner portion of the packaging box (102) in the longitudinal sectional view. (See FIG. 5). By simultaneously contacting the two inner surfaces of the upper corner of the packaging box at the upper side and the outer side, the storage position of the piece is not easily shifted, and the function of pushing in the vertical and horizontal directions is sufficient. Fulfill.

  Each vertical plate (4) is composed of a connecting piece connected from the side portion of the inner plate (2) surrounding the side portion of the article (O) to be packed, and the connecting piece has a valley with an obtuse bending angle outward. It will be folded and will be in the state which spread to diagonally outward with respect to each inner side board (2) (refer the broken line arrow of FIG. 4). The vertical plate (4) is erected in a state of being firmly supported in the vertical direction by being connected from each side portion of the inner plate (2) folded back in the vertical direction.

  Moreover, in the cushioning material for packing of the said Examples 1-10, an inner side board (2) consists of a trapezoid board of the upper convergence shape which formed the lower side longer than the upper side, and a vertical board (4) is an unfolded state. In the trapezoidal plate of the adjacent inner plate, a part of one side part in a specific direction is partially cut away to form a connecting piece connected to the other side part in the specific direction of the inner plate. By vertically bending the boundary (24F) in the valley fold direction with an obtuse bending angle of more than 90 degrees and less than 180 degrees, the vertically converged vertical piece formed with the upper side longer than the lower side in the assembled state is the upper space (S1). ) And the side space (S3).

  According to the said structure, each vertical board (4) cuts off the specific other side of the adjacent inner side board (2), and is connected and formed in the specific one side of the inner side board (2) used as connection object. (See, for example, FIGS. 1 and 2). In particular, by partially cutting a specific direction side portion of each of the plurality of inner plates (2), the other side portion is partially strengthened without reducing the formation and overall strength.

  Moreover, according to the said structure, in order to ensure a vertical board (4) by notching an inner side board (2) without notching a top board (1), ensuring a sufficient protection surface by a top board (1), The formation area of the vertical plate can be obtained relatively freely. For example, in addition to the trapezoidal partial cut line (4C) as shown in FIG. 1, various cut partial lines (4C) shown in FIG. The selection of any one of these partial cut lines (4C) means that the shape of the vertical plate is changed according to the side protection strength required for the inner plate (2), and the vertical plate (4) is interposed. This is a buffering adjustment method for adjusting the regulation strength or buffering property.

  Moreover, in the cushioning material for packing of the said Examples 1-11, a packing box comprises the accommodation space of the planar view square shape which has four corner parts by planar view. Each of the plurality of vertical plates (4) includes four vertical pieces that extend one by one toward all of the corners and are in contact with the inner surfaces of the corners. The vertical plate (4) composed of the four vertical pieces expands along the diagonal line of the planar shape of the packing box (102), is accommodated in the polygonal corner of the packing box, and is viewed in plan view of the vertical plate (4). Movement in the direction is restricted. The buffering direction due to the interposition of the vertical plate is specified in one direction of the accommodated corner, so that the buffering function to the outside of the corner stored and two sides in a plan view of the packaging box adjacent to the corner The buffer function in each direction is exhibited. Further, if the number of vertical plates is three or more, it has a buffering function in three or more directions in plan view, and the circumferential uniformity of the buffering function is improved.
