＜手順１＞
手順１では、図１に示すとおり、外装容器となる段ボール箱１の蓋を開けて開口させた状態（開口部２）にする。
段ボール箱１は、予め粘着テープなどで閉塞された底面１１、４つの側面２１〜２４、４枚の蓋３１〜３４を有しているものである。なお、閉塞前の底面１１は、４枚の蓋３１〜３４と同様のものである。
手順１では、４枚の蓋３１〜３４は、底面１１とほぼ平行になるように拡げられている。
段ボール箱１の上方には、次の手順２で使用するプラスチック製の内袋４０が示されている。
段ボール箱１の大きさは特に制限されるものではないが，例えば、縦４００〜５００ｍｍ、横２５０〜３５０ｍｍ、高さ３５０〜４５０ｍｍのものを使用することができる。
段ボール箱１は、外形が直方体または立方体であるものが好ましいが、それらに限定されるものではなく、外形が円柱形状のもの、角柱形状のものなどでもよい。 <Procedure 1>
In procedure 1, as shown in FIG. 1, the lid of the corrugated cardboard box 1 serving as an outer container is opened and opened (opening 2).
The cardboard box 1 has a bottom surface 11, four side surfaces 21 to 24, and four lids 31 to 34, which are closed in advance with an adhesive tape or the like. The bottom surface 11 before closing is similar to the four lids 31 to 34.
In the procedure 1, the four lids 31 to 34 are expanded so as to be substantially parallel to the bottom surface 11.
Above the cardboard box 1 is shown a plastic inner bag 40 used in the next step 2.
The size of the cardboard box 1 is not particularly limited, but, for example, a length of 400 to 500 mm, a width of 250 to 350 mm, and a height of 350 to 450 mm can be used.
The cardboard box 1 preferably has a rectangular parallelepiped or cubic outer shape, but is not limited to these, and may have a cylindrical outer shape, a prismatic outer shape, or the like.

＜手順２、２'＞
手順２では、図２（ａ）に示すとおり、開口部２からプラスチック製の内袋４０を入れて、内袋４０の袋口４１を段ボール箱１の開口部２の４枚の蓋３１〜３４に沿って外側に拡げる。
内袋４０の大きさ（容積）は、段ボール箱１の内部の底面１１と４つの側面２１〜２４に接触した状態で配置できるものが好ましい。 <Procedures 2 and 2'>
In step 2, as shown in FIG. 2( a ), the plastic inner bag 40 is inserted from the opening 2, and the bag mouth 41 of the inner bag 40 is inserted into the four lids 31 to 34 of the opening 2 of the cardboard box 1. Spread outward along.
The size (volume) of the inner bag 40 is preferably that which can be arranged in contact with the bottom surface 11 and the four side surfaces 21 to 24 inside the cardboard box 1.

手順２'では、その前段階（図１の手順１）において、図２（ｂ）に示すように段ボール箱１の４枚の蓋３１〜３４が４つの側面２１〜２４と同一面を形成するように保持された状態にする。
段ボール箱１が未使用の場合には、図２（ｂ）に示す状態にすることは容易であるが、必要があれば、蓋３１〜３４が４つの側面２１〜２４の境界部分に柔軟性のある枠体、ゴムバンドなどを嵌め込んで図２（ｂ）に示す状態にする。
手順３'では、図２（ｂ）に示す状態の段ボール箱１の開口部２からプラスチック製の内袋４０を入れて、内袋４０の袋口４１を段ボール箱１の開口部２の４枚の蓋３１〜３４に引っかけるようにして外側に折り曲げる。 In step 2′, in the previous step (step 1 in FIG. 1), the four lids 31 to 34 of the cardboard box 1 form the same surface as the four side surfaces 21 to 24 as shown in FIG. 2(b). So that it is held.
When the cardboard box 1 is unused, it is easy to bring it into the state shown in FIG. 2B, but if necessary, the lids 31 to 34 are flexible at the boundary portions of the four side surfaces 21 to 24. A frame body, a rubber band, or the like having a groove is fitted to obtain the state shown in FIG.
In step 3′, the plastic inner bag 40 is inserted from the opening 2 of the cardboard box 1 in the state shown in FIG. 2B, and the bag opening 41 of the inner bag 40 is inserted into the opening 2 of the cardboard box 4 by four pieces. Bend outward as if hooked on the lids 31-34.

＜手順３＞
手順３では、図３（ａ）に示すように、床面１１０上に置いた振動機１００の加振テーブル１０１の上に段ボール１の底面１１を置いた状態で、段ボール箱１に対して振動を加えながら、段ボール箱１内に樹脂付着長繊維ペレット５０を連続投入する。
このとき、段ボール箱１に対して上下方向に振動を加える方法が好ましく、上下方向および左右方向に振動を加える方法がより好ましい。なお、左右方向にのみ振動を加える方法では十分にかさ密度を大きくすることができない。
このようにして段ボール箱１に対して所定方向に振動を加えながら樹脂付着長繊維ペレット５０を詰め込むと、図３（ａ）から図３（ｂ）のように、樹脂付着長繊維ペレット５０のかさ密度を速やかに大きくして、見かけの量を少なくすることができるため、詰め込み時間を短縮できるほか、樹脂付着長繊維ペレット５０の収容量も多くする（収容後のかさ密度を大きくする）ことができるようになる。

In step 3, as shown in FIG. 3A, the cardboard box 1 is vibrated with the bottom surface 11 of the cardboard 1 placed on the vibration table 101 of the vibrator 100 placed on the floor surface 110. While adding, the resin-attached long fiber pellets 50 are continuously charged into the cardboard box 1.
At this time, a method of vertically vibrating the cardboard box 1 is preferable, and a method of vertically or horizontally vibrating is more preferable. Note that the bulk density cannot be sufficiently increased by a method of applying vibration only in the left-right direction.
When the resin-attached long fiber pellets 50 are packed into the cardboard box 1 while vibrating in a predetermined direction in this manner, the bulk of the resin-attached long fiber pellets 50 is changed as shown in FIGS. 3(a) to 3(b). Since the density can be rapidly increased to reduce the apparent amount, the packing time can be shortened, and the amount of the resin-adhered long fiber pellets 50 stored can be increased (the bulk density after storage can be increased). become able to.
As described above, the resin-attached long fiber pellets 50 may be packed while applying vibration, or the resin-attached long fiber pellets 50 may be packed and then vibrated.

A method for accommodating a rod-shaped molded article, wherein the rod-shaped molded article is accommodated in a container,
6 to 50 mm in which the rod-shaped molded body is integrated with the reinforcing long fiber bundle in which the reinforcing long fibers are bundled in a state of being aligned in the longitudinal direction, by adhering the molten thermoplastic resin thereto. Resin-attached long fiber pellets cut into a length of 0.5 to 10 mm in diameter, an aspect ratio of 5 to 100, and a density of 0.90 to 3.80 g/cm ³ ,
When accommodating the rod-shaped molded body in the container, with the container opened, a vertical vibration is applied to the container so that the vibration width of the container is 0.2 to 3.5 mm. While or while the rod-shaped molded body is housed in the container, the vibration width of the container relative to the container is 0.2 to 3.5 mm with the container opened. A method for accommodating a rod-shaped molded body in which vibration is applied in the vertical direction.

A method for accommodating a rod-shaped molded article, wherein the rod-shaped molded article is accommodated in a container,
The rod-shaped molded body, reinforcing long fibers bundled in a state in which reinforcing long fibers are aligned in the lengthwise direction, the surface of the reinforcing long fiber bundle is coated with a thermoplastic resin in a molten state, And, the resin-impregnated long-fiber pellets, which are impregnated into the reinforcing long-fiber bundle and are integrated into one, are cut into a length of 6 to 50 mm and have a diameter of 0.5 to 10 mm, an aspect ratio of 5 to 100, and a density. 0.90~3.80g / cm is ³ things,
When accommodating the rod-shaped molded body in the container, with the container opened, a vertical vibration is applied to the container so that the vibration width of the container is 0.2 to 3.5 mm. While or while the rod-shaped molded body is housed in the container, the vibration width of the container relative to the container is 0.2 to 3.5 mm with the container opened. A method for accommodating a rod-shaped molded body in which vibration is applied in the vertical direction.

A method for accommodating a rod-shaped molded article, wherein the rod-shaped molded article is accommodated in a container,
The rod-shaped molded body, reinforcing long fibers bundled in a state in which reinforcing long fibers are aligned in the lengthwise direction, the surface of the reinforcing long fiber bundle is coated with a thermoplastic resin in a molten state, A resin-attached long-fiber pellet in which the reinforcing long-fiber bundle is integrated without being impregnated into the reinforcing long-fiber bundle and cut into a length of 6 to 50 mm, having a diameter of 0.5 to 10 mm and an aspect ratio of 5 to 100, The density is 0.90 to 3.80 g/cm ³ , and
