Description

  The present invention relates to a packing cushioning material used for protecting an object to be packed from an impact or the like when the object to be packed is packed and transported.

When packing an object to be packed such as a product in an outer box, a packing cushioning material is stored together with the product to protect the product.
As a packing material for packing a so-called built-in stove that is dropped into a countertop of a system kitchen and packed in an upper open outer box, for example, there is one disclosed in JP-A-2005-313977.
This is made by folding a pair of corrugated cardboard sheets, and placing a pair of side pads (4) (4) that are assembled symmetrically along the left and right side walls of the stove body along the side walls of the outer box. As shown in FIG. 6, the rear pad (41) positioned behind the stove body, the bottom pad (42) for placing the areas near both ends of the bottom of the stove body, and the stove body Side pads (40) positioned on both the left and right sides are provided.
When the side pad (4) is housed in the outer box so that it is located on both the left and right sides of the stove body, the rear pad (41) absorbs the impact from the rear to the outer box, and the bottom impact is the bottom pad. (42) absorbs, and the impact from both the left and right sides is absorbed by the side pads (40), and the stove body is packed in a state protected from external impact.
FIG. 6 shows the side pad (4) positioned on the left side when viewed from the front of the outer box.

The side pad (40) is configured as a hollow rectangular cylindrical body having a depth substantially equal to the lateral length of the side wall of the outer box and opened to the front and rear, and an inner plate (402 ) And an outer plate (403) located on the outer box side, and an upper plate (401) and a lower surface (404) that connect these upper and lower sides to each other and maintain a horizontal posture. A bottom pad (42) is placed on the part extended inward.
The side pad (40) has a certain strength in the front-rear direction due to its shape, and is not easily crushed against an impact from the front. As a result, if the front end of the side pad (40) is protruded forward from the front surface of the stove body, the impact from the front of the outer box will be received by the front end of the side pad (40). The front side will be protected. Further, when the side pad (40) receives an impact from the side, the outer plate (403) is deformed inward and the hollow state of the side pad (40) is slightly crushed, thereby absorbing the impact. The side surface of the stove body can be protected.

JP 2005-313977 A

However, in this case, the upper plate (401) of the side pad (40) has a certain level of overall strength against impact from the side, and is in a horizontal posture because it has a structure that is not easily crushed. The impact received from the side of the upper plate (401) may be transmitted to the packaged item as it is.
For this reason, in the side surface portion of the object to be packed, when the strength of the portion where the upper plate (401) abuts is relatively weak, the side surface portion is recessed or deformed by the upper plate (401), and the object to be packed is There is an inconvenience of damaging it.

  The present invention has been made in view of the above circumstances, and in a cushioning material for packing that is housed along at least one side wall of an outer box and is installed on the side of an article to be packed, the longitudinal direction along the side wall An object of the present invention is to improve the cushioning function against the impact from the side by making it easy to be crushed against the impact received from the side while maintaining the strength.

The present invention taken in order to achieve the above-mentioned object has “a side pad that is positioned along at least one side surface of an article to be packed that is stored in the outer box,
The side pad includes an inner plate positioned along the side surface portion of the object to be packed, an outer plate positioned along the side wall of the outer box facing the side surface portion, and between the inner plate and the outer plate. And a hollow substantially rectangular tube body provided with an upper plate connected to each other via an inner fold line and an outer fold line,
The inner fold line and the outer fold line are provided along the longitudinal direction of the upper plate,
The upper plate has inner notches toward the inner fold line and outer notches toward the outer fold line, and the inner notches and outer notches are alternately formed in the longitudinal direction. '' It is.

The technical means operates as follows.
The side pad is housed in the outer box so that the outer plate is positioned along one side wall of the outer box, and the predetermined side surface portion of the package is along the inner plate of the side pad. Store the item to be packed in the outer box. In this stored state, an upper plate is interposed between the side wall of the outer box and the side portion of the package, and an outer fold line that opens the outer notch corresponds to the side wall of the outer box. The inner fold line where the inner notch is opened corresponds to the side portion of the package. These inner notches and outer notches are alternately formed in the longitudinal direction of the upper plate so that one outer notch is located on the outer bend line between two adjacent notches on the inner bend line, for example. Yes.

Since the upper plate has the above-mentioned shape, a certain strength is maintained in the longitudinal direction, and the upper plate is not easily crushed in the longitudinal direction even when an impact is applied to the upper plate in the direction of pressing the end in the longitudinal direction. . On the other hand, it is weak against an impact from a direction perpendicular to the longitudinal direction, and the portion where the inner notch or the outer notch is formed is configured to easily deform upon receiving the impact.
Therefore, when an impact is applied from the outside to the portion of the side wall of the outer box corresponding to the upper plate, the impact is transmitted to the upper plate of the side pad via the side wall, As described above, since the inner notch and the outer notch are alternately opened, the impact is received in the non-formed area of the outer fold line in the outer notch, and is transmitted while being dispersed to the non-formed area of the inner fold line. It will be.
In addition, the region where the inner notch or the outer notch is formed is more easily deformed with respect to the impact than these non-formed regions and can sufficiently absorb the impact, and can soften the impact applied to the object to be packed. .
In addition, an impact is not transmitted to the part which the notch of an upper board respond | corresponds in the said side part of a to-be-packaged item.

In the packing cushioning material, “at least one of the inner cutout and the outer cutout straddles at least one of the inner fold line and the outer fold line and continuously opens to at least one of the inner plate and the outer plate. It's desirable.
In this case, for example, when a side pad is assembled by folding corrugated paper in an unfolded state, at least one of the inner notch and the outer notch is punched in such a manner as to include at least one of the inner bend line and the outer bend line. Therefore, in an assembled state, at least one of the ridge lines formed at the boundary portion between the upper plate, the inner notch, and the outer notch, whose strength is increased by bending, is partially cut away. For this reason, the upper end region of the side pad is easily crushed by the impact from the side, and can sufficiently absorb the impact, so that the impact transmitted to the packaged item can be further alleviated.
In addition, according to the above-described formation of the notches, the corrugated cardboard can be easily folded accurately along the inner fold line and the outer fold line.

In the packing cushioning material, it is preferable that “at least one of the inner notch and the outer notch has an arcuate corner portion”.
In this case, at least one of the inner notch and the outer notch has a shape having an arcuate corner portion, and has a shape without an angular portion. Therefore, even when the outer notch is deformed by an external impact, it is angular. The inconvenience that the upper plate is easily broken from the portion can be prevented.

In the packing cushioning material, “the arcuate corner portion is formed in both the inner notch and the outer notch,
It is preferable that the inner notch and the outer notch are arranged so that each arcuate corner portion corresponds to both sides in the width direction orthogonal to the longitudinal direction of the upper plate.
Although the inner notch and the outer notch are alternately formed in the longitudinal direction of the upper plate, each arcuate corner portion is positioned on both sides in the width direction perpendicular to the longitudinal direction of the upper plate. There are portions where the inner notch and the outer notch are simultaneously opened on both sides of the. As a result, the strength in the width direction is lower than that in which the notch is opened only on one side of the upper plate, and it is more easily crushed against an impact from the side wall direction of the outer box. Therefore, it is possible to sufficiently absorb the impact received by the upper plate and further alleviate the impact transmitted to the package.

In the packing cushioning material, “the inner cutout and the outer cutout are on the other side corresponding to the arcuate corner portion of either the inner cutout or the outer cutout that opens to one side in the width direction of the upper plate. In the range, the other arcuate corner part of the inner notch or outer notch and the corner part formed by the arcuate corner part and the inner fold line or the outer fold line correspond to each other. Is desirable.
In this case, the arcuate corner portion is positioned on one of the both sides along the longitudinal direction of the upper plate, and the corner portion formed between the arcuate corner portion and the high-strength ridge line is arranged on the other side corresponding thereto. Since it is set as the structure to position, fixed intensity | strength can be provided to the part which an outer notch and an inner notch overlap in the said width direction. Thereby, the intensity | strength with respect to the impact of each notch can be ensured, relieving the impact from a side with each notch.

In the packing cushioning material, it is desirable that “the inner notch is formed longer than the outer notch”. By setting the length of the inner notch opened to the packaged object side longer, the number of contact points of the upper plate with the packaged object is reduced, so that the problem of damaging the packaged product can be further prevented. .
Note that the lengths of the inner notch and the outer notch include individual lengths as well as the total length open on the inner fold line and the outer fold line.

Since the present invention has the above configuration, the present invention has the following specific effects.
The upper side plate of the side pad maintains a constant strength in the longitudinal direction along the side wall of the outer box and maintains a configuration that is not easily crushed from both ends in the longitudinal direction. If it is stored in the outer box in a manner that protrudes to the side, the impact from the front of the side wall of the outer box will be received by the end of the upper plate in the longitudinal direction, and the impact will be transmitted to the object to be packed. Can be prevented.
Moreover, the impact received from the side can be released from the inner notch and the outer notch provided alternately in the longitudinal direction of the upper plate, and is distributed without being concentrated on a part and transmitted to the package. At the same time, the upper plate itself is easily crushed by the impact from the side, and can sufficiently absorb the impact. As a result, the impact transmitted by the upper side plate to the package is weakened, and even when the strength of the side surface of the package to which the upper plate corresponds is weak, the portion is recessed or deformed. Inconvenience of being damaged can be prevented, and the packaged item can be reliably protected.

  Depending on the shape, size and number of inner notches and outer notches, as well as the location of formation, the strength of the upper plate against impacts from the side can be adjusted. It is possible to provide a buffer material having strength.

It is a perspective view of the side pad as a conventional cushioning material for packing.

The best mode for carrying out the present invention will be described below with reference to the accompanying drawings.
The embodiment of the present invention is applied to a cushioning material for packing a built-in stove having a stove body (3) and a stove top plate (31), and FIG. 1 is an exploded view showing a state of packing using the same. It is a perspective view.

  As shown in the figure, the stove in this embodiment is formed on the countertop of the system kitchen from the upper end edge of the stove body (3) provided with a grill part (35) in the center and three gas burners. It is a so-called built-in stove in which an outer peripheral flange portion (36) for supporting the periphery of the opened opening is horizontally extended outward, and a stove top plate is provided on the upper surface of the outer peripheral flange portion (36). (31) is placed and used.

  The stove top (31) is configured to have a size substantially matching the outer peripheral flange (36) and has three burner openings for exposing the burner heads (3a) (3b) (3c) of the gas burner. (30a) (30b) (30c) are formed. Rings (37a), (37b) and (37c) for placing the five virtues (33a), (33b) and (33c) are fixed around the burner openings (30a), (30b) and (30c), respectively. An exhaust guard (34) is set in the exhaust opening at the rear.

The outer box (1) for storing the built-in stove according to the above-described embodiment is opened to the upper side made of corrugated cardboard of a size that allows the stove body (3) and the stove top plate (31) to be bundled with various cushioning materials. It is a rectangular box, left and right side walls (1a) (1b) located on the left and right side surfaces (32a) (32b) side of the stove body (3), and front side wall (1c) located on the grill part (35) side And a rear side wall (1d). From the upper ends of the left and right side walls (1a) (1b) and the front and rear side walls (1c) (1d), four lid pieces (11a) to (11d) are connected to each other, and from the lower ends, Four bottom plates are connected.
Cut out the corrugated cardboard along the specified development, fold along the boundary line between the left and right side walls (1a) (1b) and the front and rear side walls (1c) (1d), and the base edge of the bottom plate, and overlap If each part is fastened with tape, the upper open outer box (1) having lid pieces (11a) to (11d) at the upper end is completed.

Next, the lower support pads (2a) and (2b) as packing cushioning materials stored along the left and right side walls (1a) and (1b) of the outer box (1) will be described.
The lower support pads (2a) and (2b) are also constructed by assembling corrugated paper, and are configured symmetrically in order to be positioned along the left and right side walls (1a) and (1b) of the outer box (1). The FIG. 2 is a developed view of the lower support pad (2a) of the lower support pad (2a) (2b), which is positioned on the left side wall (1a) side toward the outer box (1), and FIG. It is a perspective view which shows the assembled state.

  The corrugated paper is cut along the outer periphery of the developed view of FIG. 2 and is punched out along a solid line provided inside to form a cut and a notch. Then, by folding and assembling along the dotted line in the figure, a stove support pad (21) for supporting the lower left end of the stove body (3) as shown in FIG. A lower support pad (2a) having a substantially L-shaped planar shape is completed from the rear pad (22) disposed behind the main body (3).

  The stove support pad (21) of the lower support pad (2a) is a hollow rectangular cylindrical body that is long along the depth direction of the left side wall (1a) of the outer box (1) and has a substantially L-shaped longitudinal section. The lower left end of (3) is placed and the lower pad (21a) that supports the stove main body (3) from below, and the lower left end of the stove main body (3) that is connected to the left side of the upper surface from the side It consists of a side pad (21b) to support.

In the assembled state, the side pad (21b) includes an inner plate (211) positioned along the lower end of one side surface (32a) of the stove body (3) and the left side wall of the outer box (1). From the outer plate (212) located along (1a), the upper plate (213) connected to these upper end sides, and the bottom plate (214) placed on the upper surface of the lower pad (21a), It is formed in a hollow rectangular tube shape that is long in the front-rear direction of the outer box (1).
The inner plate (211), the outer plate (212), and the upper plate (213) are continuous through the inner fold line (25a) and the outer fold line (25b), respectively.

In the developed view shown in FIG. 2, two oval inner notches (20a) are punched out at predetermined positions on the inner fold line (25a), and these on the outer fold line (25b). One outer notch (20b) shorter than the inner notch (20a) is punched between the two inner notches (20a).
Thus, when the inner fold line (25a) and the outer fold line (25b) are folded and assembled into a rectangular cylindrical shape, two inner notches are formed from the upper plate (213) to the inner plate (211) as shown in FIG. (20a) and one outer notch (20b) from the upper plate (213) to the outer plate (212) are open so that they are alternately positioned in the longitudinal direction of the upper plate (213).
The lower support pads (2a) and (2b) are made of corrugated paper as described above, but the inner cutout (20a) and the outer cutout (20b) on the inner fold line (25a) and the outer fold line (25b). ), The structure is easy to bend.

In this embodiment, two front and rear inner notches (20a) and (20a) and one outer notch (20b) in the upper plate (213) are alternately formed in the longitudinal direction of the upper plate (213). However, as shown in FIG. 4, a part of the upper plate (213) is set to open simultaneously on both sides in the width direction.
Specifically, the formation area of the arcuate corner portion (200a) on the front end side of the inner notch (20a) opened toward the rear pad (22) on the inner fold line (25a) side of the upper plate (213) On the side of the outer fold line (25b) corresponding to the range (H) corresponding to a part of the arcuate corner (200b) on the rear end side of the outer notch (20b) and the outer fold line (25b). The corner (201b) on the rear end side formed at the intersecting portion is formed to correspond.
Similarly, on the inner fold line (25a) side of the outer notch (20b) corresponding to the formation area of the arc-shaped corner portion (200b) described above, the arc-shaped corner portion (200a) of the inner notch (20a) is formed. A part and a corner (201a) on the front end side formed at a portion where this part intersects the inner folding line (25a) are positioned.

  The inner notch (20a) closer to the front of the upper plate (213) and the outer notch (20b) described above are the corner (202a) on the rear end side of the inner notch (20a) and the outer notch (20b). The corner (202b) on the front end side is set so as to be located on both sides on the same orthogonal line (L) orthogonal to the longitudinal direction. That is, the front end portion of the outer notch (20b) and the inner notch (20a) closer to the front are not simultaneously opened on both sides in the width direction of the upper plate (213).

As described above, in the above-described embodiment, the inner notch (20a) and the outer notch (20b) closer to the rear of the upper plate (213) are arranged on both sides in the width direction of the upper plate (213). The arc-shaped corner (200a) or (200b) is set so that a part of the other arc-shaped corner (200b) or (200a) and the corner (201b) or (201a) correspond to each other. Therefore, the strength in the width direction of the upper plate (213) in this part is higher than that in which the arcuate corner portions (200a) (200b) are corresponded to the entire area on both sides, and the inner notch ( As in the case of 20a) and the outer notch (20b), the height is lower than that of the structure that is not opened simultaneously on both sides of the upper plate (213).
Thus, the strength in the width direction of the upper plate (213) is adjusted according to the overlapping degree of the front and rear end portions of the inner notch (20a) and the outer notch (20b) on both sides in the width direction of the upper plate (213). can do.

By forming the inner notch (20a) and the outer notch (20b) on the inner fold line (25a) and the outer fold line (25b) on both sides in the longitudinal direction of the upper plate (213), the width of the upper plate (213) Although the strength in the direction is reduced and the structure is apt to be crushed by impact from the side, a constant strength is maintained in the longitudinal direction of the upper plate (213).
Therefore, as shown in FIG. 5, the stove support pad (21) protrudes forward from the front surface of the stove body (3) where the grill portion (35) is provided and is stored in the outer box (1). In this case, the projecting portion receives the impact from the front to the lower end portions on both sides of the front side wall (1c) of the outer box (1).
In order to absorb the impact from the front, the entire area from the inner fold line (25a) to the outer fold line (25b) is further forward than the inner notch (20a) closer to the front in the upper plate (213). The upper notch (10) is opened.

  The lower support pads (2a) and (2b) assembled in a predetermined shape are stored along the left and right side walls (1a) and (1b) of the outer box (1), for example, the outer box (1) When an impact is applied from the left side to the portion corresponding to the upper plate (213) in the left side wall (1a) as shown by the arrow in FIG. 4, the impact is applied to the left side wall (1a of the outer box (1). ), The outer fold line (25b) side of the upper plate (213) is received, but since the outer notch (20b) is formed in this part, the impact is not formed in the outer notch (20b). This is distributed and received in the region, and this is further distributed and transmitted to the non-formed region of the inner notch (20a) on the inner fold line (25a) side.

In this way, the impact received by the outer box (1) can be dispersed so that no concentrated stress is applied to a part thereof, and the upper plate (213) located on the stove main body (3) side as an article to be packed Of the right side, the formation area of the inner notch (20a) does not directly contact the side surface (32a) of the stove body (3), so the right side of the upper plate (213) corresponds to the stove body (3 Even if the strength of a portion of the side surface portion (32a) is low, there is no inconvenience that the portion is recessed or deformed by the upper plate (213).
In this embodiment, the individual lengths of the inner notches (20a) are formed longer than the outer notches (20b), but a plurality of inner notches (opened toward the inner folding line (25a) ( The total length of 20a) may be set longer than the total length of the outer notches (20b) opened to the outer fold line (25b) side.

  Further, by providing the inner notch (20a) and the outer notch (20b) on both sides of the upper plate (213), the upper area of the side pad (21b) including the upper plate (213) is in the longitudinal direction. It is easy to be deformed or crushed in an orthogonal direction. In other words, since the impact from the side can be sufficiently absorbed by the upper area of the side pad (21b), the side part (32a) of the stove body (3) to which the side pad (21b) corresponds is externally applied. It can protect from an impact and can exhibit a sufficient buffer function.

  Further, depending on the degree of overlap of the inner notch (20a) and the outer notch (20b) on the inner fold line (25a) and the outer fold line (25b) of the upper plate (213), the upper plate against the impact from the side ( Since the strength of 213) can be changed, the strength of the side pad (21b) can be adjusted by the article to be packed housed in the outer box (1).

Next, a process of storing the drop-in stove in the outer box (1) using the lower support pads (2a) (2b) will be described.
First, one lower support pad (2a) is positioned on the left side wall (1a) side of the outer box (1), and the other lower support pad (2b) is positioned on the right side wall (1b) side of the outer box (1), The outer plate (212) of the side pad (21b) of each stove support pad (21) is installed in the outer box (1) so as to be along the left and right side walls (1a) (1b).
As a result, the stove support pad (21) of the lower support pads (2a) (2b) is located on the left and right side walls (1a) (1b) side of the outer box (1), and on the rear side wall (1d) side. Then, the rear pad (22) is located.
