When packing an object to be packed such as a product in an outer box, a packing cushioning member is stored together with the product for product protection.
As a packing structure 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, the one disclosed in JP 2007-161303 A has been proposed. In this case, together with the stove body, as a packing member, side pads are stored in the left and right sides of the stove body, and the front pad is stored in the outer box as a packing member in the front, and the outer peripheral flange of the upper edge of the stove body is stored. On the top, a stovetop is placed via a protective sheet, the front upper pad is packed in front of it, and the top pad is packed in the upper part, and from above, the upper open end of the outer box is attached. It has a packing structure in which the outer box is closed with four extended cover pieces.

  Various packing members such as these side pads, front pads, front upper pads, top pads, etc. are each assembled into a hollow box shape by folding corrugated paper into a predetermined shape. It protects the stove body and the stove top plate during storage and transportation by absorbing external impacts from the front, rear, left, right, and top and bottom, and preventing displacement in the outer box. Yes.

JP 2007-161303 A

  In the above-mentioned conventional one, since there are a large number of shock-absorbing members to be bundled with the stove main body as an object to be packed, a lot of shock-absorbing members must be manufactured. Since these are discarded after use, there is a problem that the environmental load is large.

  This invention is made | formed in view of the said situation, and it aims at reducing the number of the buffer members bundled with a to-be-packaged item in an outer box, and reducing an environmental load.

The present invention taken in order to achieve the above object is, `` an upper open outer box having a side wall opposed to at least one side surface of a packaged object in a stored state with a gap of a predetermined width;
A lid piece that is connected to the upper end side of the side wall and that is folded inward along the upper end side to be in a horizontal posture to close a part or all of the upper open portion of the outer box;
A spacer that is assembled by bending a punched piece formed by punching a part of the lid piece into a shape that opens toward the upper end side,
The spacer has shape holding means for holding the assembled shape, protrudes three-dimensionally along the inner surface of the side wall of the outer box from the lid piece in a horizontal posture, and at least a part of the spacer is located in the gap. is set to,
The base end side of the punched piece is located away from the upper end side of the outer box,
The spacer includes an outer buffer surface portion extending from the base end toward the inside of the outer box, an inner buffer surface portion extending obliquely upward from the lower end toward the side wall of the outer box, and the extended end to the outer buffer surface portion. An upper surface portion extending substantially horizontally toward the
Engagement protrusions are connected to the extended end of the upper surface portion, and an engagement hole is formed at a predetermined position of the outer cushioning surface portion so that the engagement protrusions can be engaged in a retaining state. That's it.

The technical means operates as follows.
The packaged item is stored in the outer box, and the lid piece connected to the upper end side of the side wall of the outer box is bent inward at the upper end side so as to maintain a horizontal posture. Block all or part.
A spacer is protruded from a part of the lid piece by punching a part of the lid piece into a shape that opens toward the upper end side, and bending and assembling the punched piece. When the lid piece is closed, it is positioned along the inner surface of the side wall of the outer box.
A gap of a predetermined width is interposed between at least one side surface of the packaged item in a state of being accommodated in the outer box and the side wall of the outer box facing the package, and at least a part of the spacer is Since it is provided so as to be located in the gap, when the upper open end of the outer box is closed with the cover plate, the spacer is positioned on the side of the packaged item in the stored state and moves to the side wall of the outer box. It functions as a cushioning member that absorbs the external impact and prevents lateral displacement of the packaged item.

In addition, since the shape of the spacer is held by the shape holding means, even if the spacer is forcibly press-fitted between the side wall of the outer box and the side portion of the packaged object and deformed, There is no loss of shape, and the assembled shape can be maintained.
In the present specification, a surface located around the packaged item in a state of being housed in the outer box is referred to as a side surface portion, and a peripheral wall of the outer box facing the side portion is referred to as a side wall. Therefore, when the article to be packaged installed vertically in use is stored horizontally in the outer box, the top and bottom surfaces of the article to be packaged in use constitute a part of the side portion.

In particular, in this case, a hollow body having a substantially triangular cross section is formed as a spacer by the outer buffer surface portion, the inner buffer surface portion, and the upper surface portion, and this is formed on the inner surface of the side wall of the outer box and the cover. It becomes the aspect interposed between the side parts of the package. The shape of the engagement protrusions provided at the extended end of the upper surface portion is maintained by engaging the engagement holes provided at predetermined positions of the outer buffer surface portion in a retaining state. The engagement protrusion and the engagement hole will function as a shape holding means, and the upper surface portion is pushed toward the outer buffer surface portion due to the impact received by the side wall of the outer box, and the outer buffer surface portion is slightly deformed accordingly, Since the spacer is not crushed and the hollow body can maintain a substantially triangular shape, it functions sufficiently as a buffer member.

Further, in the packing structure, a pair of first cuts that extend while the both open ends and the base end side of the punched piece are inclined toward each other from the open ends toward the base end side. And a pair of second cuts extending on the same line as the base end side from both extended ends of the first cut toward both ends of the base end side.
In this case, both the open ends of the punched piece and the base end portion formed shorter than the length between the both open ends are made continuous via the first and second cuts. Thereby, the impact received by the punched piece or the spacer assembled by bending it is absorbed in the first and second cut formation areas, and the punched piece or spacer is unlikely to be damaged from the base end side. Become.
Further, another invention taken in order to achieve the above object is an upwardly opened outer box having a side wall facing a side of at least one side surface of a packaged item in a stored state with a gap of a predetermined width,
A lid piece that is connected to the upper end side of the side wall and that is folded inward along the upper end side to be in a horizontal posture to close a part or all of the upper open portion of the outer box;
A spacer that is assembled by bending a punched piece formed by punching a part of the lid piece into a shape that opens toward the upper end side,
The spacer has shape holding means for holding the assembled shape, protrudes three-dimensionally along the inner surface of the side wall of the outer box from the lid piece in a horizontal posture, and at least a part of the spacer is located in the gap. Set to
The base end side of the punched piece is located on the upper end side of the outer box,
The spacer includes an upper surface portion extending in the horizontal direction from the upper end side, an outer buffer surface portion extending from the extended end into the outer box, and a lower surface portion extending in the horizontal direction from the lower end toward the side wall of the outer box. And an inner buffer surface portion extending from the extended end toward the boundary between the upper surface portion and the outer buffer surface portion, and an engaging projection piece is continuously provided on the extended end of the inner buffer surface portion. An engagement hole is formed along the boundary between the upper surface portion and the outer buffer surface portion so that the engagement protrusion can be engaged in a retaining state .
In this structure, a hollow body having a substantially triangular cross-section formed by the outer buffer surface portion, the lower surface portion, and the inner buffer surface portion is formed as an extended end of the upper surface portion as a spacer, which closes the lid plate. Interposed between the inner surface of the side wall of the outer box and the side surface of the packaged item. The engagement protrusion provided at the extended end of the inner buffer surface portion and the engagement hole provided on the boundary between the upper surface portion and the outer buffer surface portion function as shape retaining means, and the engagement protrusion is engaged with the engagement hole. By stopping, the shape of the hollow body is maintained, and even if the side wall of the outer box receives an impact and the lower surface portion and the outer buffer surface portion are slightly deformed, the spacer is not crushed, and the hollow body shape is reduced. It can hold and exhibit a buffer function.

In the above packing structure, “the remaining part of the lid piece excluding the punched piece is a pressing piece that can be pressed directly or indirectly from above on the upper surface of the packed object in the stored state”. Is desirable.
In this case, when the outer box is closed with the lid piece, the spacer functions as a cushioning member disposed on the side of the packaged object stored in the outer box to absorb the impact and to be packed. To move to the side. Moreover, the other part of a cover piece functions as a pressing piece part, and contact | abuts directly or indirectly on the upper surface of the to-be-packaged item in the accommodation state, and prevents the to-be-packaged item from rising upward.

In the above-mentioned packing structure, `` the packaged object is a heating cooker provided with a stove body and a stove top plate installed at an upper end edge thereof,
A lid piece is continuously provided at the upper ends of a pair of side walls facing each other of the outer box, and the spacer protrudes from each of the pair of lid pieces,
When the upper open portion of the outer box is closed with the pair of lid pieces, each of the spacers is inserted into the gap between the pair of both side walls of the outer box and the opposite side edges of the stovetop facing the outer box. It is desirable to have a configuration.

  When the stove body and the stove top plate are sequentially stored in the outer box, and the outer box is closed with a pair of lid pieces provided on a pair of opposite side walls, a pair of lid pieces provided on each of the pair of lid pieces Since the spacers are respectively inserted between both side edges of the stove top and both side walls of the outer box, the stove top is prevented from moving in the left-right direction.

Since the present invention has the above configuration, the present invention has the following specific effects.
The container to be packed is stored in the outer box, and the upper protruding end of the outer box is closed with the lid piece, and the spacer protruding from a part of the lid piece is placed in the storage state of the side wall of the outer box and the packed object. Since it can be made to function as a buffer member disposed between the side surfaces, it is not necessary to separately prepare a buffer member disposed on the side of the article to be packed. In this way, since the number of buffer members can be reduced, the amount of materials such as corrugated paper used for the buffer members and the amount of waste discarded after use can be reduced, which reduces the environmental burden. In addition to reducing the cost, the cost applied to the buffer member can be reduced.

  Since the spacer can be provided on the lid piece simply by bending the punched piece provided by punching a part of the lid piece and assembling it into a hollow box-like body, the production is easy. Moreover, since the shape can be held by the shape holding means, the strength against the impact received by the side wall on which the spacer is positioned can be secured, and the shape can be sufficiently functioned as a buffer member.

In addition, in the configuration in which the base end side of the punched piece constituting the spacer does not coincide with the upper end side of the outer box and has a predetermined distance, the punched piece is not easily broken from the base end side, and the cross section By using a substantially triangular hollow body, the number of bent portions is reduced, so that the manufacture of the spacer becomes easier.
By engaging engagement protrusions provided at the extended end of the upper surface portion positioned horizontally with engagement holes provided at predetermined positions of the outer buffer surface portion in a retaining state, the substantially triangular shape of the cross section is maintained. At the same time, the impact received by the side wall is received by the upper surface portion located horizontally, so that the packaged body can be sufficiently protected.

  The base end side of the punched piece constituting the spacer is provided on the upper end side of the outer box, and the spacer has an outer buffer surface portion and a lower surface portion on the extended end of the upper surface portion that extends horizontally from the upper end side of the outer box. It is good also as a structure made into the hollow body of a cross-sectional substantially triangular shape from an inner buffer surface part.

  Furthermore, in the case where the both ends of the punched piece and the base end side thereof have a continuous shape via a pair of inclined first cuts and a second cut extending on both sides of the base end side, Breakage from the base end side of the piece or spacer can be further prevented.

  Furthermore, in the structure in which the spacer and the pressing piece portion are provided at the same time on one cover piece, a buffer function is provided on the side and upper side of the packaged item in the stored state by simply closing the outer box with the cover piece. Can be made. Thereby, since a packing member is further reduced, packing work becomes easy and the workability | operativity also improves. In addition, since the weight of the entire outer box in a packed state is reduced, it is easy to carry.

  When the object to be packed stored in the outer box is a heating cooker that places the stove top on the top of the stove body, the spacer functions as a conventional side pad, and the parts other than the spacer of the lid piece are conventional Therefore, the cooking device can be easily and reliably packed with a small number of cushioning members.

The front pad (23) is arranged in front of the grille (35) on the front of the stove body (3), and includes a protective plate (23a) that protects the front of the door of the grille (35) and its left and right sides. Vertical pads (23b) (23b) that maintain the distance between the protective plate (23a) and the front side wall (1c) located on both sides, and horizontal pads that protect the door handle at the lower end of the protective plate (23a) (23c). When the front pad (23) is stored between the front side wall (1c) of the outer box (1) and the door of the grill (35), it protects the vertical pads (23b) (23b) and the horizontal pads (23c). Accessories and the like are accommodated in a range surrounded by the plate (23a) and the front side wall (1c), and a dry battery can be accommodated in the upper open portion of the vertical pads (23b) and (23b). The vertical pads (23b) and (23b) protrude downward from the horizontal pads (23c), and the overall height is set to substantially match the height of the outer box (1).

  With the stove body (3) housed in the outer box (1) together with the pair of lower support pads (2a) (2b) and the front pad (23), the lower ends on both sides of the stove body (3) Supported from below by the lower pad (21a) of the stove support pad (21) of the support pad (2a) (2b), supported from the side by the side pad (21b), and supported from the front by the front pad (23). The rear pad (22) is supported from the back, and each of these pads functions as a buffer member, so that the stove body (3) is protected from the front, rear, left and right, and the outer box (1) Movement in is prevented.

Then, the stove top plate (31) that is entirely covered with the protective sheet (29) is placed on the upper surface of the outer peripheral flange portion (36) of the stove body (3).
In the exhaust hole at the rear of the stove top plate (31), an exhaust guard (34) in a state of being stored in a storage bag is secured to the stove top plate (31) with a tape. ) Is covered with a protective sheet (29) and from the top of the protective sheet (29), the ring (37a) at the periphery of the burner opening (30a) (30b) (30c) of the stove top plate (31) ) (37a), (33b) and (33c) are installed on (37b) and (37c). From above, the upper support pad (24) is placed so as to be in direct contact with the five virtues (33a), (33b) and (33c).

  The upper support pad (24) includes an upper horizontal pad (24a) positioned along the left-right direction of the stovetop (31), and an upper vertical pad (24b) extending perpendicularly at the center and extending rearward. When the upper support pad (24) is placed on the stove top plate (31), as shown in FIG. 4, two burner openings (30a) (30a) ( The burner head (3a) (3b) of the gas burner exposed upward from 30b) and the five virtues (33a) (33b) installed in the surrounding rings (37a) (37b) are formed by the upper horizontal pads (24a). The burner head (3c) and the five virtues (33c), which are pressed from above and located at the rear center of the stove top (31), are pressed from above by the upper vertical pad (24b). The rear end of the upper vertical pad (24b) is set so as to be positioned between the rear end of the stove top plate (31) and the rear side wall (1d).

Then, the lid pieces (11a) and (11b) connected to the left and right side walls (1a) and (1b) of the outer box (1) are folded inward from above the upper support pad (24), as shown in FIG. As shown, the upper open end of the outer box (1) is closed.
As the lid pieces (11a) (11b) are tilted inward, the spacer (10) is attached to the left and right side edges of the stove top plate (31) and the left and right side walls (1a) (1b) of the outer box (1). In the final closed state where the lid pieces (11a) and (11b) have reached the horizontal position, the spacers (10) and (10) are positioned at the left and right ends of the stovetop (31). And the left and right side walls (1a) and (1b) of the outer box (1).
The spacer (10) is configured to retain the original shape by inserting the engagement protrusion (13a) into the engagement hole (13b) in a retaining state, so that the outer buffer surface portion (10b) Even if it is pushed by the stove top (31), it will not be crushed and the buffer function will not be exhibited.

In addition, in the lid pieces (11a) and (11b), the range excluding the region where the spacer (10) is formed is in the final closed state in which the lid pieces (11a) and (11b) are brought into the horizontal posture, and the upper support pads (24 ) Is set so as to function as a pressing piece (16) for pressing the upper horizontal pad (24a) from above.
The upper horizontal pad (24a) is pressed from above at the portion functioning as the pressing piece (16) of the lid piece (11a) (11b), so that the virtues (33a) (33b) are not displaced vertically and horizontally. It can be pressed and fixed on the stove top (31).

  Further, as shown in FIG. 5, when the lid pieces (11a) and (11b) are in a horizontal position, the free end sides of the lid pieces (11a) and (11b) are cut out in front of the punched portions. The presser pieces (14) and (14) are suspended, and the rear part of the presser pieces (14) and (14) presses the five virtues (33a) and (33b) and the stovetop (31) and at the same time The portion is set to a dimension that fits in front of the stove top plate (31) and supports the left and right vertical pads (23b) and (23b) of the front pad (23) from both the left and right sides. Thereby, the lateral displacement of the front pad (23) can also be prevented.

  Thus, by closing the upper open end of the outer box (1) with the lid pieces (11a) and (11b), the spacers (10) and (10) support the stovetop (31) from both sides. Upper cushioning member that functions as a cushioning member, and whose pressing piece (16) presses the stove top plate (31) and the five virtues (33a) and (33b) located on the left and right sides from above via the upper support pad (24) Therefore, it is not necessary to separately prepare a packaging member positioned on both sides or above the stove top plate (31), and the cost and labor required for packaging can be greatly reduced.

After that, the front and rear cover pieces (11c) and (11d) are closed so as to cover the cover pieces (11a) and (11b), and are fastened with tape, thereby completing the packing operation.
At this time, the lid pieces (11c) and (11d) are configured to press the upper vertical pad (24b) of the upper support pad (24) from above. As a result, the five virtues (33c) located at the rear center of the stove top plate (31) are pressed onto the stove top plate (31) by the upper vertical pad (24b).

As described above, since the cushioning member includes only the lower support pads (2a) (2b), the front pads (23), and the upper support pads (24), the conventional packing structure The number of cushioning members is reduced compared to the above, and the weight of the entire outer box in a state in which an object to be packed is stored is reduced, and transportation is facilitated.
In addition, the amount of corrugated paper used can be reduced, and the amount of waste can be reduced, thereby reducing the environmental load.

FIG. 6 is an exploded view of the outer box (100) employed in the packaging structure according to the second embodiment of the present invention.
The outer box (100) of the second embodiment is also similar to the outer box (1) of the first embodiment described above, on the left and right side surfaces (32a) (32b) of the stove body (3). The left and right side walls (1a) (1b) positioned on the side, the front side wall (1c) and the rear side wall (1d) connecting them, the left and right side walls (1a) (1b) and the front and rear side walls (1c) Lid pieces (11a) to (11d) are connected to the upper end of (1d), respectively, and bottom plates (15a) to (15d) are connected to the lower end.

Then, a part of the lid piece (11a) (11b) following the upper end side (12a) of the side walls (1a) (1b) is punched into a substantially U shape that opens toward the upper end side (12a) side, and is punched Although the piece is configured, the base end side (200) of the punched piece does not coincide with the upper end side (12a) of the outer box (1), and is positioned at a predetermined distance from the upper end side (12a).
The first and second fold lines (201) and (202) are sequentially provided in parallel with the base end side (200), and a narrow portion is formed at the center of the free end side of the punched piece. An engaging projection piece (26a) wider than that is projected.

In the second embodiment, a perforated cut is formed along the base end side (200) and the first and second fold lines (201) and (202). For this reason, even when it is folded in a direction perpendicular to the streaks of the cardboard paper, it is easy to bend.

It is located in the gap (S) in an inclined state where the portions abut.

Since the engagement protrusion (26a) is inserted into the engagement hole (26b) in a retaining state, the shape of the hollow body having the substantially triangular cross-section described above can be maintained, so that the outer buffer surface portion (20a) At the same time that the predetermined part is pushed to the side by the stove top plate (31), the bent part along the second fold line (202) is inward by the left and right side walls (1a) (1b) of the outer box (100). Even if the insertion mode is pushed, the hollow body is not crushed, can exhibit a sufficient buffer function, and sufficiently absorbs the impact received by the left and right side walls (1a) (1b) of the outer box (100). can do.
Further, in the state where the stove body (3) is not stored, the spacer (20) is in a state where the lower end portion of the outer buffer surface portion (20a) is slightly inclined toward the center of the outer box (100). Therefore, when the outer cushioning surface part (20a) is forcibly pushed to the side by the left and right ends of the stove top plate (31), the return force acts, and the left and right ends of the stove top plate (31) are moved from both sides. It will be pushed. Accordingly, the stove top plate (31) is supported from both sides by the spacer (20).

In each of the above-described embodiments, the gas stove is adopted as an object to be packaged. However, the present invention is not limited to this as long as the object has a shape having a side surface with which the spacer can come into contact in the housed state. .
Further, as in the above embodiments, the spacer may be provided on both of the pair of double-opening type lid pieces and positioned along the inner surfaces of both side walls of the outer box. It may be of a type that is provided and positioned only along one side wall of the outer box, or may be of a type that is provided on a single piece of a single-open lid.

  In each of the above embodiments, the stove main body (3) as an article to be packed is stored in the outer box (1) (100) so that the outer peripheral flange (36) is located at the upper end, and the stove top plate The spacers (10) and (20) are positioned between the left and right side edges of (31) and the left and right side walls (1a) and (1b) of the outer box (1) and (100).
