Description

  The present invention relates to a packing tray for storing an object to be packed such as a machine part, and more particularly to a packing tray suitable for holding and transporting an object to be packed.

  Conventionally, among articles to be packed such as machine parts constituting an industrial machine or a vehicle, a light and small packaged article is packed by a vacuum-formed packing tray. The packing tray is formed with a storage recess for storing the packaged object according to the shape of the packaged object. Such an article to be packed is transported as a packing body in a state of being stored in the storage recess of the packing tray.

  However, an object to be packed packed in the packing tray may jump out of the storage recess due to vibration during transportation. In view of such a point, as shown in FIG. 6, a protruding portion 66 that protrudes inward to be engaged with the article to be packed P <b> 1 is formed on the side wall portion 65 a of the storage recess 65 of the packing tray 60. (For example, refer to Patent Document 1 or Patent Document 2). Due to the protrusion 66, the protrusion 66 is locked to the article to be packed P1 in the storage recess 65 at the time of conveyance, so that the object to be packed P1 can be prevented from jumping out of the storage recess 65.

  However, in order to form such a projection 66, the end 66 a on the bottom 65 c side of the storage recess 65 of the projection 66 should be formed so as to spread from the opening 65 b of the storage recess 65 toward the bottom 65 c. The mold must be undercut. And when releasing a shaping | molding die, what is called a shaping | molding die is forcibly extracted and the packaging tray 60 in which the projection part 66 was formed is shape | molded. In this case, the shape of the protrusion 66 is easily deformed by the undercut of the mold. For this reason, depending on the shape of the projection 66 due to this deformation, there are many cases where the locking function does not work.

  Furthermore, even if the projection 66 can be formed into a desired shape, the package P1 is taken out when the package P1 is stored in the storage recess 65 of the packaging tray or from the storage recess 65. In this case, the article to be packed P1 has to get over these protrusions 66. However, when the height of the protrusions 66 is high or the number of the protrusions 66 is large, the article to be packed P1 may not be easily put in and out of the storage recess 65.

  The present invention has been made to solve such a problem, and the object of the present invention is to prevent the object to be packaged from popping out of the storage recess during transportation and the like. It is an object of the present invention to provide a packaging tray that is easy to carry out and that allows an object to be packed to be easily taken in and out of a storage recess.

  In order to solve the above-mentioned problems, the inventors have made extensive studies, and as a result, the conventional packaging tray has a structure that holds the package to be popped out in the upper part of the storage recess for storing the package. However, the problem described above has occurred, but if the structure for holding the packaged goods is held by pressing the side surface of the packaged goods during storage, the moldability of the packaging tray is improved, and further New knowledge was obtained that it was also possible to easily take in and out the object to be packed from the recess.

  In view of such a point, the packing tray according to the present invention is a packing tray in which a storage recess for storing an object to be packed is formed, and the bottom surface of the packing tray is formed from the bottom surface. A protruding columnar part is formed, and the columnar part is deformed while at least the upper part is moved by a pressing force acting from a side surface of the packed object when the packed object is stored, and the columnar part It is formed so as to urge the side surface on which the pressing force is applied by a restoring force due to deformation of the column, and the pressing force is applied to the columnar portion in a state where the article to be packed is stored in the storage recess. A contact surface that is in contact with a side surface of the object to be packed, which is different from the side surface that acts, is formed.

  According to the present invention, when the article to be packed is stored in the storage recess of the packing tray, the upper part of the columnar part is deformed while moving due to the pressing force acting from the side of the article to be packed, and the columnar part is deformed. The side surface on which the pressing force is applied can be urged by the restoring force of. Further, the contact surface of the columnar portion is in contact with the side surface of the object to be packed different from the side surface on which the pressing force acts in a state where the side surface on which the pressing force is applied is biased.

  According to the present invention, the packed object abuts on the contact surface of the columnar part, and the packed object is held in the storage recess by the restoring force of the columnar part. When the body is transported, it is possible to prevent the packaged items from jumping out of the tray.

  Further, since the stored article to be packed is held in the storage recess only by the restoring force acting on the side surface of the article to be packed, the packaged article can be easily taken out from the storage recess. Further, such a columnar portion can be formed by a forming die without being forced to form an undercut.

  Here, the “columnar portion” referred to in the present invention is deformed while at least the upper part is moved by the pressing force acting from the side surface of the packaged object when storing the packaged object, and is restored by the deformation of the columnar part. `` It is formed to urge the side surface to which the pressing force is applied by force '' means that the columnar part is deformed while the upper part of the columnar part is moving in a state where the article to be packed is stored. It has a thickness, material (for example, hardness), size, shape, etc., and when the columnar part is deformed in this way, the deformed columnar part is restored to return to its original shape It means that the columnar part is formed so as to have a thickness, a material (for example, hardness), a size, a shape, and the like that can exert a force (repulsive force against deformation) on the side surface of the package. .

  Further, as a more preferable aspect, the packing tray has a plurality of storage recesses, and the columnar portion is stored in the storage recess adjacent to the packing recess in a state in which the article to be packed is stored. An abutting surface for an adjacent to-be-packaged object that abuts the side surface of the to-be-packaged object is formed.

  According to this aspect, by further providing the contact surface for the packed object adjacent to the columnar portion, the side surface of the adjacent packed object can be brought into contact with the adjacent contact surface for the packed object. As a result, the objects to be packed (adjacent objects to be packed) stored in the adjacent storage recesses can also be held in the tray.

  Furthermore, as a preferable aspect, the base end portion of the columnar portion has an R shape. According to this aspect, even if the columnar portion is deformed when the packaged item is stored, the base end portion has an R shape, so that the columnar portion is easily deformed without being crushed, and the side surface of the packaged item is deformed. Thus, the restoring force can be applied more reliably.

  According to the present invention, it is possible to prevent the object to be packed from popping out of the storage recess during transportation and the like, and it is easy to mold, and the object to be packed is easily taken in and out of the storage recess.

  A packing tray 10 shown in FIG. 1 is a tray for packing an article P to be packed. The upper portion of the packaged object P is formed with a protruding portion Pt protruding on one side, and the protruding portion Pt has a V-shaped groove portion Pc so that the first side surface Pf and the second side surface Ps are formed. Is formed.

  The packaging tray 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), and 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 FIG. 1, a plurality of (2 × 2 pieces in FIG. 1) housing four objects to be packed P are accommodated in the molded packing tray 10 according to the shape of the lower part Pb of the object to be packed P. ) Storage recesses 11 are formed, and these storage recesses 11 are partitioned by a cross-shaped partition wall portion 12.

  Further, a columnar portion 15 protruding from the bottom surface 13 is formed on the bottom surface 13 of the packing tray 10. The columnar portion 15 is formed at a position offset with respect to the V-shaped groove portion Pc of the article to be packed P when the article to be packed P is stored.

  That is, as shown in FIG. 2, the columnar portion 15 is pressed by the side surface 15 b of the columnar portion 15 by the pressing force F <b> 1 acting from the first side surface Pf of the packaged item P when the packaged item P is stored. Then, at least the upper part 15a of the columnar part 15 is elastically deformed while moving, and is formed so as to bias the first side face Pf applied with the pressing force F1 by the restoring force F2 due to the deformation of the columnar part 15. ing.

  Further, the columnar portion 15 is in contact with the second side surface Ps of the packaged object P different from the first side surface Pf on which the pressing force F1 is applied in a state where the packaged product P is stored in the storage recess 11. A contact surface 15c is formed.

  Moreover, in order to ensure the strength of the packaging tray 10 in a state where the restoring force F2 by the columnar portion 15 is applied and the article P to be packed is stored, the thickness of the columnar portion 15 is in the range of 0.3 to 2 mm. The wall thickness of the storage recess 11 other than the columnar portion 15 is preferably larger than the thickness of the columnar portion 15 and in the range of 0.5 to 3 mm.

  According to the present invention, the package body 1 is formed by storing the article P to be stored in the storage recess 11 of the packing tray 10. Here, the article to be packed P abuts on the contact surface 15c of the columnar part 15, and the article to be packed P is held in the storage recess 11 by the restoring force of the columnar part 15, so that the article to be packed P is stored. When the packaging tray 10 (packing body 1) is transported, it is possible to prevent the article P from jumping out from the packaging tray 10.

  Further, since the stored article P is held in the storage recess 11 by the restoring force F2 acting on the first side surface Pf of the package P, the package P can be easily removed from the storage recess 11. It can be taken out. Furthermore, such a columnar part 15 can be molded by a molding die without being forced to form an undercut.

[Second Embodiment]
FIG. 3 is a schematic perspective view for explaining a packing body when an object to be packed is stored in a packing tray according to a second embodiment of the present invention, and FIG. 4 is a view of the packing body shown in FIG. It is a partial top view.

  Note that the packaging tray according to the second embodiment differs from the packaging tray of the first embodiment in the shape of the columnar part and the partition wall part, and the other parts are denoted by the same reference numerals. Detailed description thereof will be omitted.

  As shown in FIGS. 3 and 4, the partition wall portion 12A of the packaging tray 10A according to the second embodiment includes two storage recesses 11, 11 of the four storage recesses 11, 11,. 15 are formed so as to be continuous with 15 therebetween.

  The columnar portion 15 contacts the side surface Pd of the article to be packed P (P2) stored in the adjacent storage recess 11 (11B) in a state where the object to be packed P (P1) is stored in the storage recess 11 (11A). An adjacent contact surface 15d for an object to be packed (second contact surface when the contact surface 15c is the first contact surface) is formed.

  In this way, by further providing an abutment surface 15d for an object to be packed adjacent to the columnar part 15, the object to be packed P (P2) adjacent to the columnar part 15 is obtained by the movement and deformation of the object to be packed P (P1). ) Can be brought into contact with the adjacent contact surface 15d for an object to be packed. Thereby, the article to be packed P (P2) stored in the adjacent storage recess 11 (11B) can also be held in the packing tray 10A.

  Such a columnar portion 15 may be the columnar portion shown in FIG. Fig.5 (a) is a typical perspective view which shows the modification of the columnar part of the packaging tray which concerns on this embodiment, (b) is a typical perspective view which shows another modification of a columnar part. .

  As shown in FIG. 5A, the base end portion 15e of the columnar portion 15A has an R shape. By doing so, even if the columnar portion 15 is deformed when the article to be packed P is stored, the base end portion 15e has an R shape, so that the columnar portion 15A can be easily deformed without being crushed and covered. The restoring force F2 can be more reliably applied to the first side surface Pf of the package P.

  Furthermore, as shown in FIG. 5B, the side surface (specifically, at least the contact surfaces 15c and 15d) of the columnar portion 15B may be a swelled side surface. Thereby, when the second side surface Ps of the article to be packed P and the contact surface 15c come into contact with each other, the contact surface 15c is deformed so as to be crushed by the second side surface Ps of the object to be packed P. The object to be packed P can be stored (while being recessed).

  At this time, due to the elastic deformation of the contact surface 15c, the contact surface 15c on the second side surface of the article to be packed P is caused by a restoring force (repulsive force) that causes the expanded contact surface 15c to return to its original shape. Can press the article P to be packed. Similarly, the contact surface 15d is also a swelled side surface, so that the side surface of the adjacent object to be packed can be pressed by a restoring force.

  Thus, even when the packaging tray in which the article to be packed P is stored is transported, the article to be packed P is held in the storage recess 11 by the restoring force of the further contact surfaces 15c and 15d. Therefore, the to-be-packaged goods P can be prevented from jumping out from the packing tray 10.

  The embodiment of the present invention has been described in detail above, but the present invention is not limited to the above-described embodiment, and the scope of the present invention described in the scope of the claims of the utility model registration is not deviated. Various design changes can be made.

  For example, in the first and second embodiments, as an object to be packed, an object to be packed in which a V-shaped groove is formed on the upper protrusion is packed, but the object to be packed is pressed by the columnar part. The first side surface and the second side surface abutted by the columnar part, and if these side surfaces are formed, the shape of the groove is, for example, U-shaped. A groove or the like may be used. Furthermore, the structure is not limited to the groove, and may be a structure in which two members are branched and connected in the upper part of the packaged object.

  Further, in the first and second embodiments, there are 2 × 2 storage recesses for storing the objects to be packed. However, if the objects to be packed can be urged by the columnar parts, they are stored. The number of recesses is not limited.
