Packaging materials and packaging

The present invention relates to a packaging material which can be suitably packaged from at least one of a plurality of plate-shaped packages of different widths.

Conventionally, as a packaging material for packaging a package, a container body and a lid are used. The upper portion of the container body is formed with a housing recess for accommodating the packaged object through the opening, and the lid system is formed to cover the packaged object exposed from the housing recess.

For example, when a plate-shaped packaged object such as a glass substrate is packaged, a plurality of layers of the same size are stacked via a sandwich paper, and are accommodated in a housing recess of the container body. Here, when any one of a plurality of types of packages to be different in width is selected, and when a plurality of sheets are accommodated in the housing recess, it is necessary to prepare a container body in which the housing recess corresponding to the type is formed.

In view of the above, for example, a packaging material is used which is a spacer having a shape corresponding to the size of the plated body to be used at a position opposed to the side portion of the plate at the time of packaging (protective member) The protective member is fitted to the inner wall surface of the housing recess so as to be detachable (see, for example, Patent Documents 1 to 3).

In this case, even if any one of the different types of plates (packaged objects) is selected and the plurality of sheets are stacked and then packaged, the size of the plate of the selected type is selected. It is only necessary to fit the protective member and fit it into the housing recess of the container body. Therefore, the common container body and the lid can be used in combination to package the plate.

However, in the packaging materials disclosed in Patent Documents 1 to 3, the protective member can be selected in accordance with the selected packaged object, and the packaged article is packaged in a common storage body and a cover. However, it is necessary to correspond to a plurality of different widths. The package is prepared with a plurality of protective members, which not only increases the number of components as the packaging material, but also cannot store and manage the protective members that are not selected at the time of packaging.

The present invention has been made in view of the above problems, and an object thereof is to provide a packaging material which can be packaged without selecting one of at least a plurality of plate-shaped packages of different widths for packaging. Pack the case in the case of a number.

The present invention is used to solve the problem. The packaging material of the present invention is a packaging material selected from at least a plurality of plate-shaped packages of different widths and packaged, the packaging material comprising: a container body in which a container is formed a housing recessed portion for accommodating the packaged object; the lid body covers the container body so that the opening end portion formed in the housing recessed portion is sealed; and the side edge protecting member is detachably fitted to the container body or At least one of the cover bodies and protecting side edges on both sides of the selected package; the side protection members form a plurality of side protection arm portions extending radially from the shaft portion And having a length corresponding to the plurality of packaged articles; the container body or the lid body is formed with a fitting recessed portion for the front end surface of the side edge protecting arm portion corresponding to the selected packaged object The side wall surface of the housing recess is exposed to protect the side portion, and is fitted to the side protection member.

In the case of using the packaging material of the present invention, first, one selected from at least a plurality of packages of different widths is used as a package to be packaged. Next, the side protection arm portion corresponding to the selected packaged object is selected, and the side edge protection member is embedded so that the front end surface of the selected side edge protection arm portion is exposed from the inner wall surface of the accommodation recess portion. A fitting recess formed in the container body or the cover.

In this way, by arranging the side protection arm portions by fitting the packages having different widths, even if the packaged objects are packaged, the side edges of the two sides can be aligned, and one side protection is used. The member is disposed to arrange the front end surface of the side protection arm portion. As a result, even if a collision or vibration acts on the package, the front end surface of the side protection arm portion can be pressed against the side portion of the package to protect the packaged object.

In a preferred aspect, each of the side protection arm portions has an identification portion for recognizing a side protection arm portion corresponding to the selected packaged object. According to this aspect, the packaged object can be selected and the identification portion of the side protection arm portion of the side protection member can be confirmed, and the side protection arm portion can be appropriately exposed from the inner wall surface, and in this way, The side protection member is fitted to the fitting recess.

In addition, the arm for protecting the side edge of the protective member is not particularly limited as long as it extends radially from the shaft portion and has a length corresponding to a plurality of packages. However, as a preferred aspect, the side protection members extend four side protection arm portions from the shaft portion so that the side protection members have a cross shape.

According to this aspect, since the punching cushioning material is disposed on the surface of the pair of corner protecting arm portions that are fitted to the fitting portion of the container body or the lid body, the cushioning material can be protected by the cushioning material. A corner portion of the packaged object with the circuit board attached along the side of each side portion. Further, when the fitting portion is fitted, when the impact acts on the corner protecting member, the corner protecting arm portion comes into contact with the corner portion of the packaged object with the circuit board attached thereto, and the corner protecting arm portion is scratched. song. As a result, the corner portion of the second packaged object can be cushioned by the corner protecting arm portion.

In a further preferred aspect, the corner protecting member is fitted to the container body, and the corner protecting arm portion protrudes from the open end of the container body in a state of being fitted to the container body. . According to this aspect, similarly to the above-described side protection member, even if the packaged object with the circuit board is superposed and stored in the housing recess and close to the vicinity of the opening end of the container body, it is possible to borrow The corner portion protecting arm portion suppresses the corner portion of the packaged object that is superposed on the upper layer from exceeding the corner portion protecting arm portion. Thereby, the packaged article can be prevented from flying out of the packaging material.

In the container body, the side portion of the packaged object accommodated in the housing recess is provided along the side portion different from the side portion protected by the side protection member to protect the side portion. A side cushioning member is detachably provided on the inner wall surface of the housing recess.

The selected one of the packaged articles is stacked in a plurality of pieces for packaging. Further, the package PA to which the circuit board is attached and the packaged object PN to which the circuit board is not provided are the above-described four kinds of plate members having different widths.

The side edge portion 21b of the bottom surface 21a of the housing recess 21 of the container body 20 of the present embodiment is provided with a substrate housing recess 21c for housing the circuit board-attached package disposed on the bottom surface 21a along the side edge portion 21b. The circuit board Pb of the PA. By this means, when a plurality of packages PA with the circuit board attached thereto are stacked, the circuit boards Pb, Pb, ... which are fan-shaped in the vertical direction can be hidden so as not to protrude from the opening end portion 22a. It is placed in the substrate housing recess 21c.

Further, the corner recesses 21e and 21e are formed in the corners 21d and 21d on the side of the substrate housing recess 21c in which the housing recess 21 is formed. Thereby, the corner protection member 40 which will be described later can be detachably fitted to the corner recess 21e of the container main body 20.

The corner protecting members 40 and 40 protect the member to which the pair of corner portions Pc of the plate Pa on the circuit board Pb side are connected when the package PA to which the circuit board is attached is packaged.

Further, the corner protecting member body 41 is made of a material harder than the container body 20 and the lid body 10. For example, the Young's modulus of the material constituting the corner protecting member body 41 is selected to be higher than the Young's modulus of the material constituting the container body 20 and the lid body 10. In the case where the container body 20 and the lid body 10 are the above-mentioned foamed resin material, the non-foamed resin material is selected as the corner protecting member body 41, and as the material of the corner protecting member body 41, for example, polystyrene is used. A resin, a polyolefin resin, an acrylic resin, a polycarbonate, or the like.

Thereby, the corner protecting member body 41 is harder than the container body 20 and the lid body 10, and when the package PA with the circuit board attached thereto is slammed or vibrated to the packaged package body, because the load is heavy. Since the corner protecting member 40 is disposed at the corner of the housing recess 21 which is easily concentrated, the damage or defect of the container body 20 can be suppressed.

Further, the punching cushioning material 42 is a sheet which absorbs the impact from the corner portion Pc of the package PA to which the circuit board is attached, and can use natural rubber or isoprene rubber which is softer than the corner protecting member body 41. , butadiene rubber, urethane rubber, styrene-butadiene rubber, nitrile rubber, butyl rubber, ethylene propylene rubber, fluororubber, acrylic rubber, etc., or further foaming such materials, And overlap them in multiple layers.

When the package material PA with the circuit board is packaged as shown in FIG. 8 and FIG. 9( a ), the corner concave portion 21 e of the container body 20 is fitted to the corner protection members 40 and 40 . . Then, the circuit board Pb of the package PA with the circuit board is placed in the substrate housing recess 21c, and the laminated paper 21 is sandwiched between the package PAs with the circuit board. Ways to overlap them.

The container body 20 accommodating the packaged object PA is covered with the lid body 10, and the opening end portion 22a of the container body 20 is sealed. The outer edge 11 of the back surface side of the lid body 10 is fitted to the outer edge groove of the container body 20. 22b. In this fitting state, the cover body 10 and the container body 20 are tied to each other along the band grooves 18 and 28 by a resin band (not shown) such as three PP bands, thereby forming a package. .

At this time, as shown in FIG. 9(a) and FIG. 9(b), a pair of corners 21d and 21d on the side of the substrate housing recess 21c in which the recessed portion 21 is accommodated are formed, and a plate shape for protecting the package PA to which the circuit board is attached is disposed.

The corner portion Pc of the package PA (see the two-dotted line in FIG. 9(c)) with the circuit board attached to the uppermost stage is beyond the corner protecting arm portion 44. Thereby, the package PA with the circuit board attached can be prevented from flying out of the packaging material 1.

Further, when the packaged object without the circuit board is packaged, in a state where the pair of corner protecting members 40 and 40 are taken out from the container body 20, the circuitless recess 21 of the container body 20 may be housed in a closed circuitless circuit. The packaged object of the substrate. Since the size of the packaged object without the circuit board is longer than the plate shape of the package PA to which the circuit board is attached, the opening end portion 22a is slightly the same size, so that the recess 21 is formed. The inner wall surface 21f protects the state of the stored second packaged object PN.

In the case where the width of the packaged object PA on which the circuit board is attached and the packaged substrate having the circuit board are different in the longitudinal direction, the direction of the side protection member 30 may be oriented as shown in the first embodiment. In a proper direction, the side protection member 30 is fitted to the fitting recess 26, and the side edge portion of the selected package is protected by the side protection arm.

In this way, not only the packaged articles having different widths in the longitudinal direction of the plate, but also the packaged circuit board package in which the side portions Ps of the plate are connected to the circuit board Pb via the flexible circuit Pf. In the case of the object PA and any one of the packaged articles selected from the packaged substrate of the circuit-less substrate formed of a plate material, the common container body 20 and the lid body 10 can be used in combination, and the plate-like objects can be packaged.
