Description

  The present invention relates to a product storage tray for storing a relatively heavy product such as a connecting nail used by a power nailer or the like and holding the product without deformation.

  In general, when shipping products produced in the factory, the products are packed in cardboard cases such as cardboard and transported from the factory to the dealer and from the dealer to the user. When the paper case is loaded onto a pallet or car, or is transported from the car to the work site, the operator places the hand on the paper container and carries it. For example, in a connection fastener such as a connection nail used in a power nailer driven by power such as compressed air, a number of metal fasteners are connected by a flexible connection body and wound in a spiral shape. These connecting fasteners are accommodated in a cylindrical magazine formed on a tool such as a nail driver and are sequentially supplied to the driving portion by a feed mechanism formed on the tool. For this reason, if the cylindrical shape of the connecting fastener housed in a paper container or the like is deformed due to vibration during conveyance or the like, the fastener cannot be supplied. Therefore, in a packaging container for storing such a connected fastener, in order to prevent deformation of the connected fastener due to vibration during transportation, a plastic tray having a large number of cylindrical recesses is used. A plurality of connecting nails are accommodated in the recess, and a tray containing the connecting nails is accommodated in a paper case and packed.

  In addition, conventional product storage trays that store cylindrical products such as connecting fasteners such as connecting nails in paper containers use plastic material as the tray material, so when the used tray is discarded Disposal (incineration, etc.) becomes an environmental problem. At present, from the viewpoint of protecting the environment, it is desired that plastic materials should not be used as much as possible.

  For this reason, a tray made of cardboard like Japanese Patent Application No. 2004-165634 has been proposed and implemented. This tray was formed by bending side pieces at right angles from two opposite sides of the bottom plate, bending the piece between the cuts formed in parallel from the middle of the side pieces to the bottom plate in a bridging manner, and placed on the bottom plate. The bent piece is interposed between two products. Since the tray is made of paper and can be burned and discarded, there is an advantage that the burden on the environment is reduced.

  However, according to the above cardboard tray, there is no problem when one tray is stored and arranged in one cardboard box. However, when two or more trays are stored and arranged side by side in one cardboard box, each tray The side pieces were aligned on the inner surface of the cardboard box. The reason is that by using the recess formed between the bent piece and the inner surface of the cardboard box, the portion of the cardboard box corresponding to the recess is folded inward, and this part is hand-held for easy carrying. It is because it is trying to become. However, when placed side by side in this way, there is nothing between the adjacent products in the two trays, and both products are in direct contact with each other, so the cardboard boxes are in a position where the aligned trays go up and down due to some unexpected cause When the product falls, the upper product hits the lower product strongly, and both products may come into contact and deform. When used in a nail driver while being deformed, there is a problem that the nail feeding becomes poor or the nail is obliquely fed to the injection port of the nail driver and buckled.

  The object of the present invention is to provide a product storage tray that solves the above-described problems in the prior art, has a small impact on the environment, and can satisfactorily hold a product stored therein even by an impact such as dropping. And

  In order to solve the above-mentioned problem, the invention according to claim 1, the side piece is bent vertically from each side of the rectangular cardboard bottom plate, and two parallel cuts formed from the middle of each side piece to the bottom plate. A buffer part is formed by valley-folding both ends of the intermediate piece in between and a part of the intermediate piece being mountain-folded, and between the adjacent buffer parts and the adjacent side pieces having these buffer parts. A product storage space is formed.

  The invention according to claim 2 is characterized in that the end faces of a pair of side pieces facing each other among the side pieces are abutted against and fixed to the inner sides of the adjacent side pieces.

  According to a third aspect of the present invention, a flap is formed at both ends of a pair of side pieces facing each other among the side pieces, and the two side flaps are bent at a right angle, and the side pieces are adjacent to the outside of the flap. It is characterized by polymerizing other matching side pieces.

  According to the first aspect of the present invention, since the products stored in the respective storage spaces are adjacent to each other via the buffer portion, any posture when dropped in a state of being stored in a container such as a cardboard box Since there is a shock absorber between the product that is above and the product that is below it even if it is dropped, the upper product does not directly hit the lower product, so deformation due to impact is small. It can be suppressed. Moreover, since the side piece surrounds all products, it is excellent in product protection.

  According to the invention of claim 2, since the end faces of the side pieces facing each other among the four side pieces are abutted against and fixed to the inner side surfaces of the adjacent side pieces, the two trays are like cardboard boxes. When the two trays are in contact with each other when they are placed side by side in a separate container, the side piece of the side of each tray that is abutted is superposed on the inner surface of the container, and the side pieces that are abutted are superposed on each other By aligning the end faces of the container so that they contact the inner surface of the container at a substantially right angle, even if the container is accidentally dropped so that the two trays are up and down, they overlap between the upper tray and the lower tray. Since the side piece is received and supported by the end face of the side piece superposed on the inner surface of the container, it is difficult to deform. For this reason, the product of the upper tray is well prevented from impacting the product of the lower tray, and the product is not easily deformed.

  According to the third aspect of the present invention, the flaps are formed at both ends of a pair of opposing side surface pieces out of the four side surface pieces, and the side surfaces are outside the flaps in a state where both flaps are bent at a right angle. Since the other side pieces adjacent to the piece are polymerized, when the two trays are accommodated side by side in the container, the side pieces having no flap are polymerized at the site where the two trays come into contact with each other. By arranging the side flaps so that the flaps of the other side pieces face each other, even if the container accidentally drops so that the two trays are up and down, there are two sheets between the upper tray and the lower tray. A side wall piece and two flaps in total form a quadruple structure, and a quadruple wall is formed between the product below the upper tray and the product above the lower tray. Further, the side piece superposed between the upper tray and the lower tray is not easily deformed because it is received and supported by the end face of the side piece provided with the flap. For this reason, the product of the upper tray is well prevented from impacting the product of the lower tray, and the product is not easily deformed.

  FIG. 1 is a perspective view of a product storage tray for storing a relatively heavy product. For example, a cylindrical product such as a product in which a connection fastener such as a connection nail, a connection pin, and a connection screw is wound in a spiral shape is used. It is an example of a tray suitable for storing and packaging products. FIG. 2 shows a development view of the tray. The tray 1 includes a rectangular cardboard bottom plate 2 made of corrugated board, a side piece 3 bent vertically from each side, and a buffer portion formed on the bottom plate 2 from the middle of each side piece 3 in a bridging manner. 4.

  The basic form of the tray 1 of FIG. 1 can be made by valley-folding the bent portion a between the bottom plate 2 and the side piece 3 from the state of FIG.

  Next, the buffer portion 4 forms the intermediate piece 4a between two parallel cuts p, q formed from the middle in the width direction of each side piece 3 to the bottom plate, and when the tray 1 is assembled, The intermediate piece 4a is formed by folding both ends of the bent portions b and c at substantially right angles and then partially folding the bent portions d of the intermediate piece 4a at substantially right angles. The distance L1 between the bent portion d and the valley folding portion c of the bottom plate 2 is between the valley folding portion a of the side piece 3 and the valley folding portion b of the side piece 3 of the intermediate piece 4a. It is formed so as to be substantially the same as the interval L2. For this reason, the upper surface of the buffer part 4 formed by bending the intermediate piece 4 a is substantially parallel to the bottom plate 2, and the side surface of the buffer part 4 is substantially parallel to the side piece 3.

  A product storage space 6 is formed between the adjacent buffer portions 4 and the side surface pieces 3 having these buffer portions 4 and adjacent to each other. In addition, a product storage space 6 is also formed at a center portion of the bottom plate 2 and surrounded by the four buffer portions 4.

  As described above, since the tray 1 is made of paper, it can be recycled after use, and finally burned and discarded, so that the burden on the environment can be reduced.

  By the way, a product suitable for storing in the paper tray 1 is, for example, as shown in FIG. 1, a connection in which a large number of nails are connected at equal intervals by a flexible connection material such as a wire to form a spiral shape. A nail 7, which is not shown, is loaded into a cylindrical magazine provided in a tool such as a nail driver, is sequentially supplied to a driving portion by a nail feed mechanism, and is driven into a material to be driven by a striking mechanism It is.

  Next, the case where the connecting nail 7 is packaged in the product storage tray 1 having the above-described configuration will be described. Usually, as shown in FIG. 3, first, the two trays 1 are accommodated in a corrugated container 8 for a set of two. Then, the connecting nail 7 is stored in the storage space of each tray 1.

  According to the above configuration, the side piece 3 surrounds all products. Since the products 7 stored in the respective storage spaces 6 are adjacent to each other through the buffer portion 4, when dropped in a state of being stored in the container 8, the product 7 that is on the upper side and the product 7 that is on the lower side are displayed. Since the buffer part 4 exists between the upper product 7 and the lower product 7, the upper product 7 does not directly hit the lower product 7. Therefore, the product 7 is well protected without being deformed.

  In the above-described embodiment, adjacent side pieces are only slightly in contact with each other, but as shown in FIG. 4, the side pieces 3a (the other side piece 3a) facing each other among the four side pieces. Is preferably abutted against the inner side surface of the adjacent side piece 3b (the other side piece 3b is omitted), and the abutting portion is preferably fixed. As means for fixing the abutting portions of the side surface pieces 3a and 3b, adhesion by hot melt may be used, or stapling may be used.

  When the two trays 1 are accommodated in the corrugated container 8 for a set of two, the side piece 3 a that abuts the side piece of each tray 1 at the portion where the two trays 1 are in contact with each other. The side pieces 3b that are superposed on the inner surface and abutted against each other are superposed on each other, and are arranged so that their end faces 10 abut on the inner surface of the container 8 at substantially right angles. Then, the connecting nail 7 is stored in the storage space 6 of each tray 1.

  According to the above configuration, even if the container 8 is accidentally dropped in a posture in which the two trays 1 are up and down as shown in FIG. 4, the side piece 3b superposed between the upper tray 1 and the lower tray 1 is Since it is received and supported by the end face 12 of the side piece 3a superposed on the inner face of the container 8, it is difficult to deform. For this reason, the product 7 of the upper tray 1 is satisfactorily prevented from colliding with the product 7 of the lower tray 1, and the product 7 stored inside is hardly deformed and is held well.

  On the other hand, in the configuration in which the end surfaces 12 of the side pieces 3a of the adjacent trays 1 are abutted with each other, the other side piece 3b is not supported, and thus easily bends. There is a risk that the product 7 will collide with the product 7 and the parts wound in a coil shape will be crushed and deformed.

  5 and 6 show that in the tray 1 having the above-described configuration, both ends of a pair of side pieces 3a facing each other among the four side pieces are extended so that the flaps 11 can be bent. It shows an example in the case of being bent and extended so as to overlap the adjacent side piece 3b. In addition, the same thing as the example of FIG. 1 is shown with the same code | symbol.

  In this embodiment, the base part of the side piece 3a, 3b side of the intermediate piece 4a constituting the buffer part 4 is formed wide. This is to increase the strength of the buffer part 4 itself and to make the buffer part 4 closer to the cylindrical product and to reduce rattling.

  When the two trays 1 having the above configuration are put in the cardboard container 8 to store the connecting nail 7, the two trays 1 come into contact with each other when the trays 1 are put side by side as shown in FIGS. The side pieces 3b that do not have the flap 11 are superposed at the site, and are arranged so that the flaps 11 of the other side pieces 3a face each other through these superposed side pieces 3b. Then, the connecting nail 7 is stored in the storage space 6 of each tray 1.

  According to the above configuration, the products 7 stored in the storage spaces 6 are adjacent to each other via the buffer portion 4, so that deformation due to impact can be suppressed to a small level.

  Further, even if the container 8 is accidentally dropped so that the two trays 1 are vertically moved, as shown in FIG. 8, the two side pieces 3b are placed between the upper tray 1 and the lower tray 1. The two flaps 11 have a total quadruple structure, and a quadruple wall is formed between the product 7 below the upper tray 1 and the product 7 above the lower tray 1. Not only is it difficult to deform itself, but there is little risk of direct collision between products. Further, the superposed side piece 3b is not easily deformed because it is received and supported by the end face of the side piece 3a provided with the flap 11 and the flap 11. For this reason, it is well prevented that the product in the upper tray 1 impacts the product in the lower tray 1, and the product is not easily deformed.

  In addition, in this case, it is not necessary to fix the side pieces, so that assembly is easy.
