Meanwhile, on the other side of the sidewall part 12 of the housing recess 11, there is formed a second projection 14 projecting from the sidewall part 12 at a position where a gap d is formed between the projection 14 and an upper edge pb on the other side of the object to be packed P1 housed in the housing recess 11.

Description

  The present invention relates to a packing material for packing an object to be packed such as a part, and more particularly to a packing material that can suitably unpack a package in which the object to be packed is packed with the packing material.

  Conventionally, machine parts (packaged items) such as vehicle parts are packed by a packing material and conveyed. The packing material is formed with a storage recess for storing an object to be packed, and is transported as a package in a state where the object to be packed is stored in the storage recess.

  It is also conceivable that the article to be packed conveyed as a package will jump out of the storage recess due to vibration during conveyance. In view of such points, for example, as shown in FIG. 7, the packaging material 70 is formed with a storage recess 75, and a plurality of protrusions 76 projecting inwardly are formed on the side wall 75 a of the storage recess 75. , 76 (see, for example, Patent Document 1 or Patent Document 2).

  In such a packing material 70, as shown in the drawing, all the protrusions 76, 76... By providing the projections 76 in this manner, the projections 76 are brought into contact with and locked on the upper edge pt of the packaged item P in the storage recess 75. Even if this occurs, it is possible to suppress the to-be-packaged item P from popping out of the storage recess 75.

JP 2001-48269 A JP 2002-302114 A

  However, when packing with the above-described packing material 70, popping out of the packing object P can be suppressed due to vibration during transportation or the like, but the packing object P is taken out from the packing material 70 (the packing body 7 is unpacked). ), Since all the protrusions 76, 76 of the storage recess 75 are in contact with the upper edge pt of the package P, the package P is directed toward the opening 75a of the storage recess 75. It must be moved linearly upward (see arrow in FIG. 7).

  Then, by such a linear movement, when the side surface ps of the article to be packed P tries to get over all the projections 76 and 76 at the same time, the opposing projections 76 and 76 are separated (that is, the storage recesses). The housing recess 75 of the packing material 70 must be deformed so that both sides of 75 are spread. Due to this deformation resistance, the article to be packed P may not be easily removed from the storage recess 75, and the workability of unpacking may be reduced.

  The present invention has been made in view of such points, and the object of the present invention is to unpack the container even when a protrusion for preventing the packaged item from popping out from the storage recess. An object of the present invention is to provide a packing material that can easily take out an object to be packed from a storage recess.

  In order to solve the above-mentioned problems, the inventors focused on the movement of an object to be packed at the time of unpacking as a result of intensive studies. In other words, if the object to be packed can be taken out by turning (turning) from the storage recess instead of moving it linearly upward (toward the opening of the storage recess) and taking it out, We obtained new knowledge that the packaged item can be easily taken out without the side of the package getting over all the protrusions at the same time.

  The present invention is based on this new knowledge, and the packing material according to the present invention is a packing material in which a storage recess for packing an article to be packed is formed, and one of the side walls of the storage recess. On the side, a first protrusion is formed that protrudes so as to come into contact with the upper edge of one side of the article to be packed stored in the storage recess, and on the other side of the side wall of the storage recess The second protrusion protruding so as to form a gap on the opening side of the storage recess is formed with respect to the upper edge of the other side of the article to be packed stored in the storage recess. Features.

  According to the present invention, in the state where the article to be packed is stored in the storage recess (packed state), the first protrusion protrudes so as to come into contact with the upper edge portion on one side of the article to be packed. The object is fixed on one side. On the other hand, a gap is formed between the second protrusion and the upper edge of the other side of the package, but the package is about to jump out of the storage recess due to vibration or the like on the other side In this case, the upper edge of the other side of the article to be packed is locked by the second protrusion. As a result, when the package is transported, even if vibration or the like occurs, it is possible to prevent the packaged item from jumping out of the storage recess.

  In addition, when the package is unpacked, a gap is formed between the upper edge portion and the second protrusion on the other side of the package, so that the package is stored in the storage recess. Using the bottom of the other side of the object as a turning axis, it is possible to easily turn one side of the packed object so as to get over the first protrusion. Thereby, the latching state of the upper edge part of the one side of a to-be-packaged object, and the 1st protrusion can be cancelled | released. After that, if the locked state is released and the posture is inclined (while maintaining this inclination angle), the upper edge of the other side of the article to be packed can be moved by relatively moving the packing material and the article to be packed. The packed object can be easily taken out from the storage recess without overcoming the second protrusion.

  Here, “one side of the side wall of the storage recess” as used in the present invention refers to the side facing the one direction from the center of the storage recess, and “the other side of the side wall of the storage recess” It refers to the side facing the direction opposite to one direction from the center of the recess. Similarly, “one side of the article to be packed” refers to the side facing the one direction from the center of the article to be packed, and “the other side of the article to be packed” is one direction from the center of the storage recess. Means the opposite side.

  If it is possible to prevent the packaged item from popping out of the storage recess during conveyance and to remove the packaged item from the storage recess during unpacking as described above, the gap between the second protrusion and the packaged item can be reduced. The size is not particularly limited. However, more preferably, when the article to be packed is inclined from the packed state in the storage recess, the gap is such that the bottom of the article to be packed on the one side is closer to the storage recess than the first protrusion. The upper edge portion of the object to be packaged on the other side is formed so as to be located closer to the bottom surface side of the storage recess than the second protrusion.

  By forming such a gap, when the other side of the packaged object stored in the storage recess is pivoted on the other side, the second protrusion is easily rotated. Without touching the object, the object to be packed can be surely passed over only the first protrusion, and the object to be packed can be taken out from the storage recess.

  The number of the first protrusions and the second protrusions is not particularly limited as long as it is possible to surely prevent the object to be packed from popping out from the storage recess during the conveyance. However, as a more preferable aspect, at least two of the first protrusions are formed on the side wall portion on the one side. According to this aspect, if there are a total of three protrusions (three points) including at least two first protrusions and at least one second protrusion, the object to be packed can be stably locked in the storage recess. can do.

  Moreover, if the to-be-packaged item can be swung as described above, the shape of the recess such as the storage recess is not particularly limited. However, as a more preferable aspect, an overhanging recess that protrudes from the storage recess is formed on one side of the storage recess in which the first protrusion is formed.

  According to this aspect, by inserting a hand or a finger into the overhanging concave portion and pushing up a part of the object to be packed upward, the object to be packed can be easily turned as described above. Further, it is not easy to visually recognize the difference between the first protrusion and the second protrusion and specify the turning direction. However, in this aspect, in the vicinity of the portion where the protruding recess is formed, Since it can be determined that the protrusion is formed, the turn direction can be easily specified by turning the turn direction.

  Further, when a plurality of articles to be packed are conveyed at a time, it is preferable that a plurality of storage recesses are formed in the packing material. In such an aspect, the first and second protrusions may be formed on either the central side or the edge side, but as a more preferable aspect, the first protrusion is on the central side of the packing material. Preferably, the second protrusion is formed on the edge side of the packing material.

  By forming the first protrusion on the center side of the packing material and forming the second protrusion on the edge side of the packing material, the object to be packed is moved from the center of the packing material toward the edge during unpacking. Can be swiveled. The central part of the packing material is more rigid than the edge part of the packing material, and it is difficult to deform due to its own weight, so the deformation of the packing material when unpacking is suppressed, The packaged item can be stably taken out from the storage recess.

  In this way, when the packing object is stored in the above-described storage recess of the packing material to form a packing body, when the packing body is unpacked, the other side of the packing object in a state of being stored in the storage recess With the bottom of the swivel as a pivot axis, one side of the package is swiveled with respect to the packing material so as to get over the first protrusion, and then the tilted angle with respect to the package is maintained. By moving the package relatively, the packaged object can be unpacked.

  According to the present invention, even when a protrusion for preventing the packaged item from popping out is provided from the storage recess, the packaged item can be easily taken out from the storage recess during unpacking.

It is CC sectional view taken on the line of b), (b) is sectional drawing which showed the state which turned the to-be-packaged item with respect to the packing material.

  A packing material 10 (tray) shown in FIG. 1 is a packing material for packing an object to be packed P1 in which a protruding portion p2 is formed on a plate-like base p1. The packaging material 10 is formed by integrally molding a sheet-like thermoplastic resin, for example, by a thermoforming means such as vacuum forming. Examples of the material include polyolefin resins such as polypropylene (PP) and polyethylene (PE), polystyrene (PS) resins such as impact-resistant polystyrene (HiPS), or polyester resins such as polyethylene terephthalate (PET). The material is not particularly limited as long as it is a resin that can be thermoformed.

  As shown in FIGS. 1-3, the packing material 10 is rectangular shape, and the skirt part 18 is formed so that it may hang down from the periphery. Further, a storage recess 11 for storing the article to be packed P1 is formed inside the packing material 10. A pair of first protrusions 13 and 13 and a pair of second protrusions 14 and 14 are formed on the side wall 12 of the storage recess 11 toward the internal space of the storage recess 11.

  The first protrusion 13 is an upper edge portion on one side of the base p1 of the article to be packed P1 in a packed state in which the article to be packed P1 is stored in the receiving recess 11 on one side of the side wall portion 12 of the storing recess 11. It protrudes from the side wall portion 12 so as to come into contact with pa.

  On the other hand, on the other side of the side wall portion 12 of the storage recess 11, the second protrusion 14 is in a packed state in which the package P1 is stored in the storage recess 11, and is on the base p1 on the other side of the package P1. It protrudes from the side wall part 12 at a position where a gap d is formed between the edge part pb.

  More specifically, as shown in FIG. 3B, when the article P1 is tilted (turned) from the packed state (the state shown in FIG. 3A) in the storage recess 11, the gap d The bottom part (one side bottom part) pc of the article to be packed P1 on one side is located closer to the opening 11a side of the storage recess 11 than the first protrusion 13, and the upper edge part pb of the article to be packed P1 on the other side. However, it is formed so as to be positioned on the bottom surface 11b side of the storage recess 11 with respect to the second protrusion 14.

  In this way, by using the packing material 10 in which the first and second protrusions 13 and 14 are formed in the storage recesses, the packing state of the packaged object P as shown below can be secured and the unpacking operation can be performed. Can be easily performed.

  Specifically, as shown in FIGS. 2 (b) and 3 (a), in a state where the packaged object P is stored in the storage recess 11 and packed, the first protrusion 13 is not packed. Since it protrudes so that it may contact | abut with the upper edge pa of one side of the thing P1, it is being fixed by the one side of the to-be-packaged goods P1.

  On the other hand, as shown in FIG. 2A and FIG. 3A, a gap d is formed between the second protrusion 14 and the upper edge portion pb of the other side of the article P1. However, when the base p1 is about to jump out of the storage recess 11 by vibration or the like on the other side, the upper edge pb of the other side of the article P1 is locked by the second protrusion 14. . As a result, even when vibration or the like occurs when the packing body 1 is transported, the locked state between the packing material 10 and the article to be packed P1 is ensured. It is possible to suppress the package P1 from popping out.

  Further, when taking out the article to be packed P1 from the packing material 10, a gap d is formed between the upper edge portion pb and the second protrusion 14 on the other side of the article to be packed P1. The bottom pd on the other side of the article to be packed P1 stored in the storage recess 11 is set as the pivot axis L (see FIGS. 1 (a) and 3 (a)) so as to get over the first protrusion 13. The protruding portion p2 of the article to be packed P1 can be gripped and one side thereof can be easily turned as shown by the arrow in FIG. Thereby, the latching state of the upper edge pa of one side of the article to be packed P1 and the first protrusion 13 can be released.

  After that, if the object to be packed P1 is moved relative to the packing material 10 in a tilted position after being released from the locked state (so as to maintain this inclination angle θ), the other side of the object to be packed P1 is moved. The to-be-packaged item P1 can be easily taken out from the storage recess 11 without the upper edge portion pb getting over the second protrusion 14.

  In particular, when the object to be packed P1 is tilted from the packed state, the gap d is formed so as to satisfy the positional relationship between the object to be packed P1 and the first and second protrusions 13 and 14, thereby storing the object. When the other side bottom pd of the article to be packed P1 stored in the recess 11 is set as the turning axis L, the one side of the article to be packed P1 is not easily contacted with the second protrusion 14 In addition, it is possible to reliably get over the base p1 only over the first protrusion 13 and take out the article P1 to be packed from the storage recess 11.

  FIG. 4 is a schematic perspective view for explaining an operation of taking out an object to be packed from the packing material according to the second embodiment of the present invention. The difference between the packaging material according to the second embodiment and the packaging material of the first embodiment shown in FIG. 1 is the shape of the storage recess. Therefore, the structure which has the same function as the packaging material of 1st Embodiment attaches | subjects the same code | symbol, and abbreviate | omits the detailed description.

  As shown in FIG. 4, the packaging material 10A according to the present embodiment is a packaging material suitable for packaging a plate-shaped article P2 having no irregularities on the surface, unlike the article P1 shown in FIG. is there. Specifically, an overhanging concave portion 15 is formed in the packing material 10A so as to project toward the edge portion 10a so as to form a continuous space from the storage concave portion 11.

  The overhanging recess 15 is provided on one side of the storage recess 11 in which the first protrusion 13 is formed, and the package is in a state of being stored in the storage recess 11 by an operator putting a finger or hand when unpacking. The space is such that the object P2 can be taken out.

  By providing such an overhanging concave portion 15, a hand or a finger is inserted into the overhanging concave portion 15 even in the case of the to-be-packaged item P2 in which the protruding portion p2 is not formed, such as the to-be-packaged item P1 shown in FIG. Thus, by pushing up a part of the article to be packed P2 upward, the article to be packed P2 can be easily turned as described above.

  Moreover, even if it is a case where any of the to-be-packaged goods P1 and P2 shown in 1st and 2nd embodiment is unpacked, the difference between the 1st protrusion 13 and the 2nd protrusion 14 is confirmed, and to-be-packed Although it is not easy to specify the direction in which the objects P1 and P2 are turned, it is confirmed that the first protrusion is formed in the portion where the protruding recess 15 is formed by providing the protruding recess 15. The overhanging recess 15 can be used to turn the packages P1 and P2 in an appropriate turning direction.

  FIG. 5 is a schematic top view showing a modification of the first and second embodiments, and (a) is a top view showing a modification of the packaging material according to the first embodiment. ) Is a top view showing a modification of the packaging material according to the second embodiment, and the difference from the first and second embodiments is the position of the second protrusion. Therefore, the structure which has the same function as the packaging material of 1st and 2nd embodiment attaches | subjects the same code | symbol, and abbreviate | omits the detailed description.

  As shown in FIG. 5A, the first projections 13 and 13 of the packaging material 10B according to this modification are arranged at the same position as the packaging material 10 shown in FIG. The other side of the side surface of the storage recess 11 is arranged along the turning axis L. By arranging in such a position, it is possible to turn the article P1 to be packed with a smaller gap d (see FIG. 2A) than the packing material 10 of FIG.

  Further, as shown in FIG. 5B, the first protrusions 13 and 13 of the packaging material 10C according to this modification are arranged at the same position as the packaging material 10A shown in FIG. The protrusion 14 is arranged along the turning axis L on the other side of the side surface of the storage recess 11.

  By arranging at such a position, the packaged item P2 is placed in the first space with a smaller gap d (see FIG. 2 (a)) than the packing material 10A of FIG. 4 as in FIG. 5 (a). It can be swung larger than that of the embodiment. In addition, according to this modification, the number of the second protrusions 14 is reduced from two to one, but the two first protrusions 13 and 13 and at least one second protrusion 14 are reduced. If there are a total of three protrusions (three points), the article to be packed P2 can be stably locked in the storage recess 11.

  FIG. 6 is a schematic diagram for explaining a state in which an object to be packed is unpacked from the packing material according to the third embodiment of the present invention, where (a) is a perspective view and (b) is a top view. It is. The packaging material according to the third embodiment is different from the packaging material according to the first embodiment shown in FIG. 1 in the number of storage recesses and the shape thereof. Therefore, the structure which has the same function as the packaging material of 1st Embodiment attaches | subjects the same code | symbol, and abbreviate | omits the detailed description.

  As shown in FIGS. 6A and 6B, the packaging material 10D according to the present embodiment has two (plural) storage recesses 11 and 11 formed therein. Each of the storage recesses 11 and 11 has a symmetrical shape with respect to the center line C of the packaging material 10D, and these storage recesses 11 and 11 are continuous spaces by the protruding recesses 15A. The projecting recess 15A functions in the same manner as the projecting recess 15 of the packaging material 10A shown in FIG.

  Furthermore, a pair of 1st protrusion 13 contact | abutted to the upper edge part pa of one side of the to-be-packaged goods P2 is formed in the center side of 10D of packing materials. On the other hand, the second protrusion 14 for forming a gap with the upper edge portion pb on the other side of the article to be packed P2 is on the edge side of the packaging material 10D along the turning axis L of the packaging material 10D. Is formed.

  According to the packing material 10D configured as described above, as shown in FIG. 6A, the first protrusion 13 is formed on the center side of the packing material 10D, and the second protrusion 14 is formed at the edge of the packing material 10D. By forming on the part side, at the time of unpacking, the to-be-packaged item P2 can be turned as shown from the center of the packing material 10D toward the edge thereof.

  Here, unlike FIGS. 6 (a) and 6 (b), when the first protrusion is formed on the edge side of the article to be packed and the second protrusion is formed on the center side of the packing material, it is opened. At the time of packing, the packaged item is turned from the edge of the packing material toward the center thereof. However, in this case, when trying to get over the first protrusion, the edge of the packing material is deformed so as to be lifted together with the object to be packed, and workability may be reduced. In particular, when the skirt portion 18 is formed as in the present embodiment, the rigidity of the edge portion of the packing material is increased, and deformation that causes the edge portion of the packing material to be lifted is suppressed. In the case of non-packing materials, this phenomenon becomes significant.

  However, when the first protrusion 13 is formed on the center side of the article to be packed P2 as in this embodiment, the center side portion is more rigid than the edge side, and other objects to be packed are included. Since it is difficult to deform due to its own weight, the packaging material (tray) 10D is hardly deformed as described above, and the packaged item P2 can be stably taken out from the storage recess 11 without the above-described deterioration in workability.

  Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the above-described embodiments, and various designs can be made without departing from the spirit of the present invention described in the claims. It can be changed.

  In all of the above-described embodiments, the skirt portion is formed on the packaging material. However, the skirt portion is not necessarily required as long as the rigidity of the packaging material can be maintained. In the first and second embodiments, at least two first protrusions are provided. However, the number of the protrusions is limited as long as the object to be packed can be locked together with the second protrusions. It is not something. Furthermore, in the third embodiment, the packaging material provided with two storage recesses is illustrated, but the number of storage recesses is as long as a series of operations of packing, conveyance, and unpacking can be easily performed. It is not particularly limited.
