The problem to be solved by the invention

However, the above-mentioned packaged objects include not only the plate-shaped packaged objects P2 shown in (b) of FIG. The packaged object P1 to which the circuit board Pb is connected via the flexible circuit Pf.

When such a packaged object P1 is packaged, even if the spacers shown in Patent Documents 1 to 3 are used, when vibration or shock acts, the flexible circuit Pf will bend due to its flexibility. . Therefore, it is difficult to effectively protect the side portion Ps with the flexible circuit Pf by the spacer.

Therefore, in such a case, it is necessary to newly prepare a container body having a storage recess corresponding to the shape of the flexible circuit Pf and the circuit board Pb, and it is difficult to use a general-purpose container body and lid for these packaged objects P1, P2 for packing.

The present invention has been made in view of this point, and its object is to provide a packaging material that can be used even if the packaged object is connected to the circuit board by a flexible circuit at the side of the board and the packaging material is only composed of a board. In the case of any one of the packaged objects, the packaging material can also use the general-purpose container body and lid to package these packaged objects.

solutions to problems

The present invention is made to solve the above problems. The packaging material of the present invention is a packaging material for selecting any one of at least two types of packaged objects for packaging. The at least two types of packaged objects include: The side part of the plate is connected with the first packaged object of the circuit board and the second packaged object constituted by the rectangular plate through the flexible circuit, it is characterized in that the above-mentioned packaging material includes: a container main body, which is formed for accommodating A storage recess of the object to be packaged; and a cover for covering the container body so as to seal the opening end formed in the storage recess, and a side edge of the bottom surface of the storage recess is formed with, In the substrate accommodation recess for accommodating the circuit board of the first object to be packaged, a corner protection member is provided at a corner of the storage recess on the side where the substrate accommodation recess is formed, and the corner protection member is detachable. It fits in at least one of the container body or the lid, and is used to protect the corner of the plate of the first object to be packaged.

According to the present invention, when the first packaged objects are packaged, the first packaged objects are stacked in the storage recess so that the circuit boards of the first packaged objects fall into the substrate storage recess. At this time, since a pair of corner protection members for protecting the corners of the board of the first object to be packaged are arranged at a pair of corners of the storage recess on the side where the substrate storage recess is formed, the second 1. The side of the packaged object to which the circuit board is connected via the flexible circuit is packaged.

Furthermore, when packaging the second objects to be packaged, the second objects to be packaged may be stacked and stored in the storage recess of the container body with the pair of corner protection members removed from the container body. Accordingly, the second packaged object can be protected by the inner wall surface of the storage recess. In this way, even if any one of the packaged object in which the circuit board is connected to the side of the board via the flexible circuit and the packaged object composed of only the board is selected, the general-purpose The container main body and the lid package these packaged objects.

In addition, the shape of the corner protection member is not particularly limited as long as it can protect the corner of the board of the first packaged object, for example, a part of a block-shaped cushioning material can be used to match the board of the first packaged object. The shape of the corners is recessed in a manner corresponding to the shape and the like.

Moreover, as a more preferable technical solution, the above-mentioned corner protecting member includes: a protecting member main body, which is formed with a fitting portion and a pair of corner protecting arm portions, and the fitting portion is used to cooperate with the above-mentioned container main body or the lid body.

As shown in FIGS. 1 to 6 , the packaging material 1 is a packaging material for packaging objects to be packaged, such as a plurality of glass plates, on top of each other. Specifically, the packaging material 1 is used to select any one of at least two types of packaged objects, and to stack multiple sheets of the selected packaged objects for packaging. The at least two types of packaged objects include: as shown in Figure 13 As shown in (a), the first packaged object P1 with the circuit board Pb connected to at least one side part Ps of the rectangular plate Pa via a flexible circuit (thin film circuit) Pf and shown in (b) of FIG. 13 The second packaged object P2 consisting of boards.

The packaging material 1 includes a lid body 10 and a container body 20 . The material of the lid body 10 and the container body 20 is preferably a thermoplastic resin foam molding. Examples of thermoplastic resins include polystyrene resins, polyolefin resins (such as polypropylene resins, polyethylene resins), polyester resins (such as polyethylene terephthalate, polybutylene terephthalate) Glycol ester, polynaphthalene dicarboxylic acid, or polylactic acid), or polycarbonate resin, etc., can use a single resin or a composite of multiple resins. When the object to be packaged is a glass plate or an electronic component, it is preferable to use a foaming raw material that has undergone an antistatic treatment as the packaging material.ビーズNSELM), ピオセラン (registered trademark) L series (LP-30ENTR, etc.), O series (OP-15ENS), S series (SP-40DNT), etc.

As shown in FIG. 1 , the size of the short side direction and the long side direction of the cover body 10 is consistent with the size of the container body 20, and a plurality of strip-shaped grooves 18 are formed on the cover body 10 along its short side direction and thickness direction. , 18,... The outer peripheral edge 11 on the back side of the cover 10 protrudes from the back as a convex line, and fits into an outer edge groove 22b formed outside an opening end (opening) 22a of the storage recess 21 described later. In this way, the container main body 20 can be covered with the lid body 10 so that the opening end 22 a of the storage recess 21 formed in the container main body 20 can be hermetically sealed.

The container body 20 has a bottom 23 and sidewalls 24 standing from the periphery of the bottom 23 , and a storage recess 21 for storing objects to be packaged is formed in the center of the container body 20 by the bottom 23 and the sidewalls 24 . Belt-shaped grooves 28 , 28 , .

In addition, a substrate storage recess 21c is formed on the side edge 21b of the bottom surface 21a of the storage recess 21. The substrate storage recess 21c is arranged on the bottom surface 21a along the side edge 21b and accommodates the circuit board Pb of the first packaged object P1. . Thereby, when stacking a plurality of packaged objects P1, the circuit boards Pb, Pb... that bulge in a fan shape in the vertical direction can be dropped in the board storage recess 21c so as not to protrude from the opening end 22a.

Further, corner recesses 21e, 21e are formed at a pair of corners 21d, 21d on the side of the housing recess 21 where the substrate housing recess 21c is formed. And the bottom surface 21g of the corner recessed part 21e is formed in the position lower than the bottom surface 21a of the accommodation recessed part 21. As shown in FIG. In this way, the corner protection member 30 described later can be detachably fitted into the corner recess 21e of the container body 20, and since the corner protection member 30 abuts against the bottom surface 21g, the packaged object P1 can be suppressed. The corner Pc is drilled under the corner protection member 30 . Also, a pair of recesses 21h are formed at each corner on the side opposite to the side where the board accommodating recess 21c is formed so as to avoid contact with the corners of the board Pa.

The corner protection members 30 and 30 are members for protecting the pair of corners Pc on the side of the circuit board Pb of the sheet Pa connected to when the first packaged object P1 is packaged. Specifically, each corner protection member 30 is composed of a protection member main body 31 and a shock absorber 32 (see FIG. 2( a ) and FIG. 3 ).

A fitting portion 33 for fitting into the corner recess 21e of the container main body 20 and a pair of corner protecting arm portions 34, 34 are formed on the protecting member main body 31. The arm portions 34 , 34 are formed integrally with the fitting portion 33 so as to extend from the corner portion 21 d of the housing recess 21 along each inner wall surface 21 f in a state where the fitting portion 33 is fitted. Furthermore, in order to prevent the stress from concentrating on the base ends between the corner protecting arm parts 34 and 34 due to the impact force acting on the corner protecting arm part 34 from the corner part Pc of the first packaged object P1, the corner Base end portions between the arm portions 34 for protection, 34 are continuous by an R-shaped curved surface 38 . Further, the shock absorbing material 32 is arranged on the surfaces of the corner protecting arm parts 34 , 34 via, for example, an adhesive or an adhesive sheet to protect the corner Pc of the panel Pa.

Here, as shown in FIG. 2( a ), the fitting portion 33 and the pair of corner protecting arm portions 34 , 34 may have a solid structure, but the fitting portion 33 and the pair of corner protecting arm portions 34 , 34 may be a hollow structure with upper and lower openings as shown in (b) of FIG. 2 , and a plurality of reinforcing ribs 34a, 34a, .

Furthermore, the protective member main body 31 is made of a material harder than the container main body 20 and the lid body 10 . For example, the longitudinal elastic modulus of the material constituting the protective member main body 31 is selected to be higher than the longitudinal elastic modulus of the materials constituting the container main body 20 and the lid body 10 . When the container main body 20 and the lid body 10 are made of the above-mentioned foamed resin material, the protective member main body 31 is selected as a non-foamed resin material, and the material of the protective member main body 31 can include polystyrene-based resins, polyolefin-based resins, and polystyrene-based resins. Resin, acrylic, polycarbonate, etc.

Next, the first packaged objects P1 are stacked in the storage recessed portion 21 with the backing paper interposed therebetween so that the circuit board Pb of the first packaged object P1 falls into the substrate storage recessed portion 21c.

The container main body 20 containing the packaged object P1 is covered by the cover body 10, and the outer peripheral edge 11 on the back side of the cover body 10 is fitted into the outer edge groove 22b of the container main body 20 so that the opening end of the container main body 20 is closed. 22a is airtight. In this fitted state, the lid body 10 and the container body 20 are bundled together along the strip-shaped grooves 18 and 28 with three resin bands (not shown) such as PP bands, thereby forming a package.

At this time, as shown in FIG. 4(a) and FIG. 4(b), a pair of corners 21d and 21d on the side of the storage recess 21 where the substrate storage recess 21c is formed are arranged with a A pair of corner protection members 30, 30 for the corner Pc of the panel Pa of the object P1. Thus, when vibration or shock acts on the package, the corner Pc on the side Ps side to which the circuit board Pb is connected via the flexible circuit Pf can be held against by the corner protection member 30 , and the inside of the storage recess 21 can be utilized. The wall faces against the other sides of the first packaged object P1.

In particular, shock absorbers 32 are disposed on the surfaces of the pair of corner protector arm portions 34, 34 extending from the fitting portion 33 of the corner protector 30, so that the first packaged object can be protected by the shock absorbers 32. The part of P1 extending from the corner Pc along each side Ps, and when packing and unpacking, the corner protection member 30 can prevent the contact between the corner Pc of the first packaged object P1 and the container main body. damage to the container body 20 due to contact.

Moreover, when an impact is applied to the corner protection member 30 in the state where the fitting portion 33 is fitted, the corner Pc of the first packaged object P1 contacts the corner protection arm portion 34, and the corner protection arm portion Section 34 flexes. As a result, the impact to the corner Pc of the first packaged object P1 can be cushioned by the corner protecting arm portion 34 .

Here, as in the modified example shown in FIG. 5 , the corner protecting arm 34 of the corner protecting member 30 may protrude from the opening end 22 a of the container main body 20 . In this way, even when the first packaged objects P1 are stacked up to the vicinity of the opening end 22 a of the container body 20 and stored in the storage recess 21 , the corner protecting arm 34 can prevent the first packaged objects stacked on the top from 1 The corner Pc of the packaged object P1 (refer to the dashed-two dotted line in FIG. 5 ) goes over the corner protecting arm 34. Thereby, it is possible to prevent the first packaged object P1 from coming out of the packaging material 1 .

Moreover, when packaging the second object to be packaged P2, as shown in FIG. What is necessary is just to stack and accommodate in the accommodation recessed part 21 of the container main body 20. Since the size of the second packaged object P2 is longer than the plate size of the first packaged object P1 in the short side direction, and is approximately equal to the size of the opening end 22a, the stored second packaged object P2 will be closed. The inner side wall surface 21f of the accommodation recessed part 21 is protected.

In this way, either one of the first packaged object P1 to which the circuit board Pb is connected via the flexible circuit Pf at the side part Ps of the board and the second packaged object P2 composed of only the board is selected and packaged. In the case of objects, these objects to be packaged can be packaged using the general-purpose container body 20 and cover body 10 .
