Description

  The present invention relates to a box-shaped packing spacer that receives a product from an upper surface opening and supports the product.

  For example, when a product W such as a charging roller used in the image forming apparatus such as a copying machine shown in FIG. 3 is transported, the product W is supported by inserting both ends in the axial direction into a holder 101 made of cardboard or the like. 101 is inserted into the box-shaped packing spacer 102 as an inner case from the opening on the upper surface and accommodated. Then, the packing spacer 102 in which the product W supported by the holder 101 is accommodated is inserted and accommodated in a similar box-shaped outer case 103 from its upper opening, and is not shown on the upper surface of the outer case 103. A lid was put on, and the outer case 103 was loaded on a vehicle or the like to transport the product.

Patent Document 1 proposes a cardboard packing for packing products.

  However, since the width dimension b2 of the conventional packing spacer 102 shown in FIG. 3 is larger than the width dimension b1 of the holder 101, the holder 101 holds the holder 101 holding the product W in the packing spacer 102. (B2-b1) is generated in the packing spacer 102, and this play causes the holder 101 to play in the packing spacer 102 together with the product W, resulting in problems such as damage to the product W due to vibration or impact during transportation. Was.

  The present invention has been made in view of the above problems, and the object of the present invention is to securely fix the product without play with a simple configuration to reliably prevent damage to the product due to vibration or impact during transportation. It is to provide a packing spacer that can be used.

  In order to achieve the above object, the invention according to claim 1 is a box-shaped packing spacer that receives and supports a product from the upper surface opening, and cuts the opposing portions of a pair of opposing side walls into a rectangular shape. A bent portion that is raised and bent inward is formed, and the distance between the tips of the opposite bent portions is set smaller than the width of the product.

  According to a second aspect of the present invention, in the first aspect of the present invention, a plurality of the bent portions are formed in the longitudinal direction of the side walls.

  According to the first aspect of the present invention, since the distance between the tips of the bent portions formed at the opposing portions of the pair of opposing side walls of the packing spacer is set smaller than the width of the product, it is held by the holder or the like. As the product is inserted into the packing spacer from above, the tips of the pair of bent portions facing each other are expanded and the product is completely inserted into the packing spacer. It is elastically supported without play by the ends of the pair of bent portions and receives an upward biasing force due to the spring property of the bent portions. Accordingly, the product is stored in the packing spacer in a state of being securely fixed without play, and damage due to vibration or impact during transportation is reliably prevented. Further, since the packing spacer is configured by a simple process of cutting and raising a cardboard or the like into a rectangular shape and bending it inward, the above-described effects can be obtained at low cost.

  According to the second aspect of the present invention, since a plurality of bent portions are formed in the longitudinal direction of each side wall of the packing spacer, a long product is reliably supported by the bent portions at a plurality of locations in the longitudinal direction without play. In the packed spacer.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  FIG. 1 is a perspective view showing a packing spacer according to the present invention and a procedure for packing a product using the same, and FIG. 2 is a cross-sectional view taken along line AA of FIG.

  In FIG. 1, reference numeral 1 denotes a holder made of corrugated cardboard or the like, and support portions 1a bent in a U-shape are formed at both ends of the holder 1 in the longitudinal direction. The holder 1 holds a product W such as a long charging roller by inserting both ends of the product W into the support portion 1a. The product W is held in the holder 1 in the present invention. Is inserted and accommodated in the packing spacer 2 according to the above.

  The packing spacer 2 according to the present invention is formed into a channel shape by folding cardboard or the like into a U shape, and its upper surface is open. Then, two opposing portions in the longitudinal direction of the pair of opposite side walls 2a of the packing spacer 2 are cut and raised in a rectangular shape, and the cut and raised portions are bent inward to form a bent portion 2b. . Here, the distance L between the ends of the pair of opposed bent portions 2b of the packing spacer 2 is set to be smaller than the width B of the product (the holder 1 that holds the product W) (L <B). ).

  Thus, when the product W is transported, as shown in FIG. 2, the product W held by the holder 1 is inserted into the packing spacer 2 from above, and as the product W is inserted, the packing spacer 2 is inserted. When the product W is completely inserted into the packing spacer 2, the tips of the pair of bent portions 2 b opposite to each other of the packing spacer 2 are pushed. Is elastically supported without play and receives an upward biasing force due to the spring property of the bent portion 2b. As a result, the product W held in the holder 1 is stored in the packing spacer 2 in a state of being securely fixed without play.

  When the product W held in the holder 1 is stored in the packing spacer 2 in a state of being securely fixed without play as described above, the packing spacer 2 that stores the product W is formed in an elongated box-like outer shape shown in FIG. It is inserted into the case 3 from above. Then, a cover (not shown) is put on the upper surface opening of the outer case 3, and the outer case 3 is loaded on a vehicle or the like to transport the product W.

  As described above, according to the present embodiment, the product W held by the holder 1 is accommodated in the packing spacer 2 in a state where it is elastically supported by the pair of opposed bent portions 2b of the packing spacer 2 without backlash. Therefore, damage caused by vibration or impact during transportation of the product W can be reliably prevented.

  Further, since the packing spacer 2 is configured by a simple process of cutting and raising a corrugated cardboard or the like into a rectangular shape and bending it inward to form the bent portion 2b, the above effect can be obtained at low cost.

  Furthermore, in this embodiment, since the bent portions 2b are formed at two locations in the longitudinal direction of each side wall 2a of the packing spacer 2, the product W such as a long charging roller has two bent portions at the longitudinal direction. It is accommodated in the packing spacer 2 in a state of being reliably supported by 2b without play. In addition, the number of the bending parts 2b formed in the longitudinal direction of each side wall 2a of the packing spacer 2 is arbitrary, and is appropriately determined depending on the length of the product.

It is a perspective view which shows the packing spacer which concerns on this invention, and the procedure which packs a product using this. It is the sectional view on the AA line of FIG. It is a perspective view which shows the procedure which packs a conventional packing spacer and a product using this.
